Introductory Delivery Speech Essay

… ¶ … Speech -- My Introduction

I'm a sophomore majoring in engineering, and while that field may not sound very interesting or fascinating to all you future movie stars, hip hop stars, future millionaires, United States Senators and cable TV talk show hosts, let me quickly remind you what some of my engineering predecessors have accomplished in America.

For example, in the 20th Century engineers are responsible for the following achievements: spaceflight, the Internet, numerous useful household appliances (dishwashers, microwaves, vacuum cleaners, and many more), the automobile, the airplane, electrification, television and radios, computers, the telephone, air conditioning and nuclear technologies.

Let's see a show of hands here, how many think that the airplane is the greatest engineering achievement of the 20th Century? You can put your hands down now, you're wrong. How about those who think spaceflight was the greatest engineering achievement? Wrong again. Okay how about computers? Hands? Anyone? Sorry, you have it wrong too. I'll give you one more. How about the invention of the automobile? Who thinks the auto was the top innovation in engineering in the 20th century? Sorry, I'll end this quiz and tell you what the National Academy of Engineering voted as the top engineering invention of the 20th Century.

It was ELECTRIFICATION. Right, the top development of the 20th century allowed electricity from a central station (fired by coal, gas, oil or nuclear) to flow outward through the country on high-tension wires, over the mountains, the fruited plains, the rivers and lakes, into the villages and cities in order to power the factories, schools, stores, hospitals and homes. Without electrification, the nation's economy would stall and children would be reading Tom Sawyer by candlelight, which isn't such a bad idea come to think of it. Save energy, light a candle and read a book.

Seriously though, speaking of the Tom Sawyer -- Huckleberry Finn… [read more]

Hardening and Tempering of Steel Term Paper

… Steel Tempering: Section 8

Increase Hardness

Strength will decrease slightly at temperatures below 400, then increase. Hardness and ductility are largely unaffected by heating at temperatures below 400, but also increase after this temperature is reached. Toughness is imparted at lower levels of heating, and can be diminished by higher heating.

The actual effects of hardening followed by quenching on steel microstructures can vary greatly depending on the specific alloy of steel being tempered, but essentially the heating allows crystalline structures to form in the steel which greatly increase the hardness of the steel, while the tempering and quenching act on these crystals to reduce fracture points and thus decrease brittleness and cracking.

Low tempering temperatures are used to increase toughness, while higher tempering is needed to increase the strength and hardness of steel. Ductility is also affected by higher heats, though to a lesser degree.

Yes

Tempering time can greatly affect the strength and toughness of the steel, with faster times (especially faster quenching) creating much more brittle steels in many instances (though this s actually reversed in certain steels). Overall, however, the temperature of the tempering process appears to have a greater effect on the mechanical properties of the steel produced.

7) There appeared to be greater change in mechanical properties at some times than would be expected based on the published literature. This variance is probably the result of a lack of true precision (and accuracy, possibly) in many measurements as well as the lack of conditions actually controlled to a point that the results of this research would be empirically valid.

8) Impact testing.

9) i. Less than 400/toughness is more important than hardness; high temperatures would cause greater brittleness, and the direction of force applied to the tool during its use could cause it to snap

ii. Temperatures of 400 and greater/the force experienced by the die is compression, and the hardness of the crystal structures formed at these temperatures is required for prolonged use

10) a. Applications: structural elements, making of intricate shapes (cutting dies) Mechanical property: ductility

b. Applications: deep-draw dies, jack-hammers

Use of Nanoparticles in Treatment of Heart Patients Research Paper

… Nano Artery

The Use of Nanoparticles as Plaque-Reducing Agents in Human Arteries

Summary of Current Approaches

Common methods for preventing the buildup of plaque in arteries, which restricts blood flow and has the potential to cause a variety of health problems based on the location of the buildup, include the use of standard stents and newer degradable stents that also employ a controlled release of pharmaceutical compounds that themselves restrict the formation and buildup of plaque in the area of the stent (Chan et al. 2010; Chorny et al. 2010; Kohn & Zeltinger 2005). The fabrication of these stents has improved to the degree that they can be made safely degradable without limitations to functionality, and this has allowed for the controlled release of pharmaceutical compounds that has greatly improved the efficacy of such treatments in the prevention of atherosclerosis and the correction of plaque build up without requiring more invasive and riskier procedures (Kohn & Zeltinger 2005). These stents actually represent two relatively recent engineering advancements in their safe degradability as well as the level of control with which the pharmaceutical-releasing action of these stents can be accomplished (Kohn & Zeltinger 2005).

Major advancements in assessment methods that lead to a determination of the need for intervention and the type of intervention recommended have also taken place in the past decade. Lesions and areas of plaque buildup that could have been repaired with stents often go unnoticed and can lead to sudden cardiac death, as the relatively invasive procedure of intravascular ultrasound was needed for detection (Schoenhagen & Nissen 2003). Newer methods of magnetic resonance imaging MRI) and computed tomography (CT) have been developed that are entirely non-invasive, however, allowing for more accurate and comprehensive assessment that in turn leads to less invasive corrections (Schoenhagen & Nissen 2003).

II. Critique of Current Approaches

Though these approaches are less invasive and more effective at both diagnosing and treating plaque buildup in arteries, and work as preventative methods that are thus more effective at reducing risks from plaque buildup than purely curative methods, there is still a fair degree of invasiveness involved in all stent procedures (Chan et al. 2010; Chorny et al. 2010; Kohn & Zeltinger 2005). In addition, though the ability for control in the rate of release of pharmaceuticals has been greatly increased with the newly-developed stents, there is still a limited window of operational capabilities in terms of timeline and in absolute amounts of drugs delivered through these stents (Kohn & Zeltinger 2005). Both of these aspects of these procedures limit their efficacy and make them undesirable in light of developing technologies (Chan et al. 2010; Chorny et al. 2010).

III. Use of Nanoparticles

Specifically, the use of manufactured nanoparticles to target areas of plaque buildup and delivery pharmaceutical compounds to these areas either as an enhancement to stent use… [read more]

Role of Engineers Book Report

… Role of Professional Engineers

This project consists of an outline of the professional roles and responsibilities of modern engineers in society. In general, engineers are responsible for the efficient application of scientific principles to benefit human societies. More particularly, engineers perform essential operational roles in many industries that could not function without their expertise. Unlike ancient engineers who trained by apprenticeships, modern engineers receive rigorous academic instruction that includes differential calculus in numerous applications. As recent events in the Gulf of Mexico and in Chile illustrate, engineers also have a profound ethical responsibility to make sure that they adhere to acceptable safety principles.

Discussion

Generally, the primary role of modern engineers is to develop methods of improving human society by contributing methods for making work easier and more productive (Harris, Pritchard, & Rabins, 2008; Johnston, Gostelow, & Jones, 1999). The myriad ways that engineers contribute to society include developing transportation systems and the construction of homes, buildings, and other physical structures. Many industries are completely dependent on engineers with specialized training and experience within those particular industries. Two industries that are currently in the news illustrate the importance of engineers: (1) deep water oil drilling, and (2) underground mining. The nation is still coping with the aftermath of BP's Deep Water Horizon disaster in the Gulf of Mexico. Currently, 33 miners are currently trapped under a collapsed mine in Chile, awaiting rescue. Within underwater oil drilling and underground mining, engineers are responsible for the design and manufacture of drilling equipment. They are also responsible for policy and procedure development, and for many aspects of administration and operational supervision of projects (Johnston, Gostelow, & Jones, 1999).

Generally, engineers share a similar formal educational background that consists of traditional core courses within modern engineering: calculus, differential equations, mechanics, fluid dynamics, and strength of materials, among others (Johnston, Gostelow, & Jones, 1999). However, engineers receive more specialized training in particular fields of interest, just as physicians all study the same core medical courses and then specialize in training in different areas of medicine. All engineers require an aptitude for understanding symbolic logic (i.e. mathematics), spatial awareness, and the ability to think critically (Johnston, Gostelow, & Jones, 1999). The particular skills required of engineers are determined by the type of work they do or the nature of the industry in which they are involved.

For example, engineers working in the deep water oil drilling industry specialize in areas such as fluid mechanics, the properties of various materials under high osmotic pressure, oil composition, and other very specific aspects of engineering science that pertains to deep water drilling. Even more particularly, some engineers in that field may focus on drafting skills (such as in connection with equipment design) while others… [read more]


Mousetrap Car Report Book Report

… Engineering Design Project -- Mousetrap Car

This project involves the development of a self-propelled vehicle from a standard mousetrap. To meet that objective, the experimenter must convert a tool designed for a specific use unrelated to locomotion (i.e. trapping mice) into a self-propelled vehicle capable of traveling 10 meters without external propulsion assistance. That process requires a practical design phase and the conceptual consideration of several conceivable approaches to the task. The selected design will be constructed and tested to determine whether the project objective has been achievable.

In general, the design process consists of conceptualizing the expected viability of all of the identifiable ways to achieve the objective. After identifying the design engineering task, the experimenter must eliminate those approaches that are valid in principle but impractical to achieve with the materials provided. Then, the remaining approaches will be considered in terms of relative likelihood of success, cost, and ease of implementation. Usually, that process will also include drawings and the construction and testing of scale prototypes to estimate effectiveness, but the most important phase is testing of the completed design.

Identifying the Engineering Task

In this case, the engineering task consists of two principal issues: (1) eliminating as much resistance (mainly friction) to efficient propulsion as possible, and (2) applying the mechanical energy potential of the mousetrap frame to produce mechanical energy that propels the device forward.

Conceptualizing and Evaluating Different Engineering Solutions

The two methods of generating mechanical propulsion were: (1) altering the trapping bar to exert backwards force against the surface of the floor to produce forward momentum, and (2) altering the trapping bar to propel a weight backwards to generate forward momentum through Newton's Second Law of Motion. In either configuration, two sets of wheels would be mounted on rotating axles. During the conceptualization phase, it was determined that the first approach was impractical because the amount of… [read more]


Synthetic Biology Most Eminent Mr. Darwin Term Paper

… Synthetic Biology

Most Eminent Mr. Darwin-

You would be most surprised, I would hazard to guess, at the many advances the science of biology has been able to take thanks to your contribution of the theory of evolution, especially when combined with technologies and discoveries in other fields. Computer technologies make tasks that would otherwise be prohibitively complicated or time consuming relatively simple and amazingly quick, and other technologies allow scientists to see ever-smaller mechanisms at work in the creation and perpetuation of life. The combination of all of these various scientific pursuits and advances is far greater than the sum of its constituent parts, and is perhaps greater than ever thought possible -- or even advisable.

You see, Charles, one of the many things that these new technologies and discoveries have led to is the establishment of a new branch of science, synthetic biology. This is the application of biological and engineering principles and techniques to the creation of synthetic life-forms, or synthetically-altered life-forms, usually for some direct and explicit practical purpose such as the secretion of a specific chemical or molecule, or performing any number of complex functions. Much of what synthetic biology attempts to do is largely harmless and without ethical issue -- the altering of E. coli bacteria to blink on and off in unison does not carry heavy ethical implications with it, and is even of relatively limited practical use (Science 2004). Other alterations could help find cures for diseases and have many other practical applications.

Other possibilities using the techniques of synthetic biology are not so certain. AMny fear that such… [read more]

Personal Statement When Asked Research Proposal

… Personal Statement

When asked where I would like to pursue my PhD in engineering management, I can never come up with an answer other than the University of Denver. This is not solely because of my positive experiences with the University of Denver during graduate school; instead, I want a PhD from a university that understands the nature of the field of engineering, a university that understands the importance of integration, invention, and progression within the engineering field. No other university has such an understanding of these variables, with special regard to the importance of cross-disciplinary knowledge in engineering. Having obtained Master's Degrees in both engineering and real estate & construction, my dream is to integrate these pursuits in a way that will allow me to pursue progressive technology in a changing world.

Throughout my educational career, I have always believed that the key to success in the field of engineering lies within the ability of the modern engineer to make connections across the disciplines. Indeed, this is what technological progress has been about since the earliest days of humans. At the University of Denver, I feel confident that I can use both my background in engineering, as well as my experience in real estate and construction to make those connections that will allow me to become an asset to this university. Working in a managerial capacity has allowed me to understand how many of these connections can be made. In the past, much of my experience has been in a managerial role, performing tasks such as achieving optimum utilization of resources, interacting with others related to the current task, and achieving communication related goals. In performing these tasks, I came to realize that many of the facets of the construction and real estate world were closely related to the field of engineering. In both… [read more]

Ergonomics Human Factors Term Paper

… Human Factors

According to Health and Safety Executive (HSE), "Human factors refer to environmental, organisational and job factors, and human and individual characteristics, which influence behaviour at work in a way which can affect health and safety." There are three separate categories for concerned with human factors: 1) the job: such as the type of task, workload, work environment, design of displays and controls, and role of procedures. Tasks should be developed with ergonomic principles in mind to account for human strengths and weaknesses, including matching the job to a person's physical and the mental strengths and limitations. 2) the individual: such as competence, skills, personality, attitude and risk perception. Individual characteristics impact behaviour in a variety of complicated ways. Some characteristics as personality are fixed and others as skills and attitudes are variable and can be improved; and 3) the organisation: such as work patterns, workplace culture, resources, communications and leadership. Such factors are frequently forgotten in job design of jobs but have a considerable influence on individual and group behaviour.

Human factor intervention, if done in an all-inclusive comprehensive way, should resolve some of the human errors that cause the injury and/or death of hundreds of individuals. For example, in the Ladbroke Grove rail collision on 5 October 1999, 31 people died and over 400 were injured. "HSE's investigation into the causes of the collision revealed what Thames Trains itself described as 'serious omissions' in its driver training programme. Michael Hodder drove his train through signal SN109 when it was showing red. There are errors and mistakes where someone does not purposely plan to hurt others.

Pursue This Degree or This Degree Combination? Term Paper

… ¶ … pursue this degree or this degree combination? How will it apply to your career goals?

Once upon a time, business employees were neatly divided into management and technical staff. The paths of these two different 'species' seldom intersected, and the two communities spoke a different language. In today's modern business world, the walls between management and technology have begun to break down. Technology is ubiquitous to every facet of commerce, and no technician can overlook the human element of technical design. As an electrical engineer, I have always prided myself on my ability to listen to customers, and to suit my designs to the human needs of those customers I serve, as well as deliver a superior technical product.

In the future, the expanding role of CIO (Chief Information Officers) in managing corporate affairs and the need for managers with technical expertise means engineers with knowledge of how to manage people and to suit designs to relate to human and commercial needs will be in increasing demand. Armed with an MBA, I seek proficiency in both my chosen field and in the science of management with the aim of becoming the ideal engineer and the ideal manager simultaneously, in all of my endeavors.

I wish to gain the necessary knowledge to sharpen my capacity to lead others in my field and in the corporate world in general. The part-time MBA would enable me to continue to learn on the job, but make my work more meaningful, as I learned to relate my experiences with others to what I was learning in the classroom.

Required Essay #2: How will your background and experience enhance the quality and diversity of the entering class of graduate business students? In what ways will you contribute to the learning experiences of your classmates?

My experience as an engineer has made me precise, rigorous, and analytical in my approach to on-the-job problem-solving. I think that my practical view of the world will be an asset to any case study or work team I am a part of in business school. Also, business problems involving technical or engineering problems would benefit from my insight in class discussion. I think I could offer valuable input about developing business solutions to suit technical needs, motivating others to use technology more effectively, and grappling with the problems of adjusting to new technology… [read more]

Crafting and Engineering Software: Contrast Term Paper

… Then he employs the practical tools and crafts of his trade to their best advantage in software construction.

While it is true that software engineers do not have an "absolutely stable core body of knowledge, and knowledge related to specific technologies will never be very stable," they "do have a body of knowledge that is stable enough to call software engineering. That core includes practices used in requirements development, functional design, code construction, integration, project estimation, cost -- benefit trade-off analysis, and quality assurance of all the rest." (McConnell, 1998) In essence, software engineering has the body of accepted troubleshooting procedures to give it the professionalism of engineering, while it still has the spontaneous 'what works for now with the tools I have,' approach that a craft often has, in a creative and interesting fashion.

Engineer a Popular Joke Posted Term Paper

… e. It is better to walk away from college with marketable knowledge and a set of skills, in addition to knowing how to express one's self and to read and think like a college graduate. I consider my love and ability of math and science great gifts. I would like to use my passions for these difficult yet rewarding subjects to give back to the world, for I know these are fields many find quite complicated. But engineers have the power to reform telecommunications, to make it easier for bridges to stand so commuters can better enter the cities of the future, and to create electrical systems that enable quicker and more functional connections between systems and humans.

Yes, the pay of engineers is also an attraction. In 2003, computer engineering graduates received the highest starting salary of all undergraduates entering the workforce -- $51,343, with electrical engineers not far behind. According to CNN Money, employers said that the students they wanted the most had degrees in electrical and mechanical engineering, followed by computer engineering. While job opportunities overall for graduates showed promise, engineers in all fields, particularly computer, electrical, and mechanical engineering were considered to be desirable and holding the greatest potential for expanding in the near and far future. Engineers were held in high social esteem, in comparison to other professions expanding such as accounting. Engineers can give back to the world, as well as reap rewards for themselves and their employers, and I am proud to come from a family of engineers, and shall hopefully count myself one of the profession's memberships in the future.

Hyatt Walkway Collapse the Kansas Term Paper

… However, the engineering firm's responsibility in the issue does not end here. The fabricator, as we know, "changed the design from a one-rod to a two-rod system to simplify the assembly task, doubling the load on the connector," which eventually was a direct cause of the collapse. The fabricator sworn under oath in court that it had telephoned the engineering firm and had obtained the approval for the modifications in the design. The engineering firm upheld that it had never received such a call. Hence, we notice here a lack of communication for which both companies are responsible. In theory, these should have worked closely together and should have cooperated on the implementation on the design and on any additional changes it had required. One phone was made from one part to the other and this was deemed not to have been received.

So, enter responsible character number 3: the fabricator. Quoting again from the engineering website at www.engineering.com,"the fabricator changed the design from a one-rod to a two-rod system to simplify the assembly task, doubling the load on the connector, which ultimately resulted in the walkways collapse." In this sentence, we have both the direct cause of the accident and the direct responsible part for it. We see here both incompetence and malevolence: the fabricator chose to modify the design so that it could assemble the structure quicker and get the work done at lesser costs. We are in no doubt about who carried the greatest responsibility of all, since it is clearly stated that this eventual change was the ultimate cause of the collapse.

Additionally, we should mention that "the engineering firm did receive revised drawings during construction and stamped them with their engineering review seal, authorizing construction," so that there is a partially divided responsibility in the end between the engineering firm and the fabricator.

Resuming those mentioned in the lines here above, there were three parts involved and responsible for the misfortune: the owner, the engineering firm and the fabricator. The owner went to all means to reduce his costs and did not accept on-site representation. The engineering firm was responsible both for the original design, which, as we have seen, did not support the minimum standard required, and because it later stamped and approved the change of plans that could only make things worse. The fabricator, finally, was guilty of consciously changing the designs in order to facilitate his work and as a direct cause of the accident.

System Operational Feasibility Great Deal Term Paper

… The other all-important aspect of a product or system's operational feasibility is maintainability. This consists of the ease, accuracy, safety and economy in the performance of the maintenance functions. If a unit is difficult to repair, the costs of a process can get completely out of hand. While the item is not functioning, interrelated processes stop and labor is at a standstill. If a system works well when it is operational, but causes significant downtime, it is not functioning as expected.

Maintainability is inherent in the product design. It is the ability of an item to be maintained, whereas maintenance is the series of actions that must be taken to restore or retain the product in an effective operational manner. Maintainability can also be defined as a characteristic in design that can be expressed in terms of maintenance frequency factors, maintenance times (or elapsed times and labor hours) and maintenance cost.

It can also be defined as a design and installation aspect expressed as the probability that: an item will be retained in or restored to a specified condition within a given period of time; maintenance will not be required more than x times in a given period, when the system is operated in agreement with prescribed procedures; and the maintenance cost for a system will not exceed y dollars per designated period of time, when the system is operated and maintained as designated.

Maintainability can be measured in terms of a combination of time elapsed, personnel labor hour rates, maintenance frequencies, maintenance cost and related logistic support factors.

In addition, good system design requires that human factors are properly integrated with the hardware, software and data. These include necessary ergonomic, human sensory, physiological and psychological factors. Design for supportability is another factor to consider. System support is defined by Blanchard as the composite of all considerations needed to assure the effective and economic support of a system throughout its programmed life cycle. The elements of support are: maintenance planning, supply support or inventory needed to support equipment, test and support equipment or tools and measurement equipment required to support maintenance, and transportation and handling that support packaging, preservation and safety.

Lastly, but just as important, a system is not feasible unless its cost for construction, operations, use… [read more]

One way the author creates a book that is relevant to the layperson and an engineering student is to use examples of everyday objects and discuss their design, concept, and engineering. The paper clip is an excellent example of one of these case studies the author uses so effectively. Thus, the book is a good introduction to mechanical engineering, and it also gives a background or history of many of the case studies, which help the reader understand the evolution to current designs and how engineering has evolved over the centuries. This is extremely helpful to students who want to understand the "why" of engineering as well as the "how." If there is anything that can be criticized about the book, it is the lack of a conclusion or wrap up of the material. The final chapter covers skyscrapers and their engineering, and the book simply ends there, and seems to leave the reader hanging. It would have been nice for the book to include a final chapter or conclusion, which wrapped up the ideas and theories in the chapters, and gave a final thought on engineering in the future. However, the author did state his feelings early in the book about the ultimate role of engineering. He said, "Engineering is the art of compromise, and there is always room for improvement in the real world" (Petroski 3). This summation of engineering is clear, succinct, and sums up his feelings well. This book makes engineering, and the study of engineering more interesting, and more real to the reader, and to the student.

Study Is to Read Term Paper

… Prior to publication, should someone else exploit material that is unpublished it is considered as stealing of intellectual property. However, it is reported that "many scientist are generous in discussing their preliminary theories or results with colleagues, and some even provide copies of raw data to others to public disclosure to facilitate related work." (Committee on Science, Engineering, and Public Policy, 1995, p.10)

However, scientists are not under any expectation to do so and reported specifically is that "during the initial stages of research, a scientist deserves a period of privacy in which data are not subject to disclosure" ensuring that the individual is able to "advance their work to the point at which they have confidence both in its accuracy and its meaning." (Committee on Science, Engineering, and Public Policy, 1995, p. 10) Therefore, publication "in a peer-reviewed journal remains the standard of disseminating scientific results." (Committee on Science, Engineering, and Public Policy, 1995, p. 10)

Data sharing during collaborations between scientists should be in the nature that promotes research in the given area and that pools all available knowledge and resources to further the area of research while ensuring that scientist are able to ensure the soundness of their findings prior to publication.

Case Studies on Life Cycle Management Essay

… Another scientific study which deftly applies the fundamental aspects of life cycle management theory to the realm of infrastructure design is titled "Life-Cycle Management of Construction Projects Based on Virtual Prototyping Technology," and the jointly authored article which was published in the Journal of Management In Engineering in 2010 provides a clear template for both public and private interests to follow. The authors argue that the traditional model of infrastructure design and implementation is fundamentally flawed based on a lack of life cycle management integration, before making the case that "owing to the different characteristics of projects or industries, the phases of project life cycle are different from each other & #8230; it has been proposed that the available life-cycle phases of conceptual, planning, testing, implementation and closure should be applied to projects" (Guo, Li & Skitmore, 2010). According to literature reviewed by the authors in this article, a foundational aspect of infrastructure design in the modern age must be the application of a life cycle sustainability assessment (LCSA) during the planning and implementation phase of complex projects. The authors assert that the LCSA now the most productive method of assessing an infrastructure project's likelihood of failure in terms of cost, schedule and effectiveness, a theory which they base on the importance of using scope control to assess a project's functionality.

Searching and Understanding a Case Case Study

… That plan might be a BIM unit or some other plan which will be included using the 3-D model. Currently, many of these project management applications as well as the 3-D designs have been created in seclusion. Obligation for the precision as well as co-ordination of price and also time setting information should be contractually resolved (Azhar, Hein and Sketo, 2008).

BIM Potential Issues

The efficiency and financial advantages of BIM towards the AEC business happen to be broadly recognized as well as progressively well grasped. Additionally, the science to apply BIM is easily accessible and quickly developing. However, BIM ownership is a lot sluggish than predicted (Azhar, Hein and Sketo, 2008). There happen to be two major reasons, technical along with managerial.

The technical factors could be extensively categorized into 3 areas (Bernstein and Pittman, 2005):

1. The necessity for well-defined transactional building procedure designs to remove information interoperability problems,

2. The prerequisites that a digitally laid out information be computable, along with

3. The necessity for well-produced functional methods for the intentional trade and implementation of significant data among the many BIM design elements.

The actual management problems group across the execution and usage involving BIM. At this time there isn't any apparent agreement as the best way to execute or make use of BIM. In contrast to a number of other building methods, there is certainly no single record or even treatise about BIM which educates on its usage or practice (AGC, 2005). A number of software companies are making money around the "buzz" involving BIM, and also have programs to deal with specific quantitative elements of it, however they usually do not treat the procedure in its entirety. There exists a demand to standardize this BIM procedure and also to determine the rules with regard to its execution. An additional controversial concern amid the AEC business stakeholders (i.e. proprietors, creative designers and engineers) is who ought to create and control the structure's data designs and in what way should the actual developmental as well as functional expenses be dispersed?

The research scientists as well as professionals need to produce appropriate answers to get over all these issues as well as other related pitfalls. As several researchers, professionals, software distributors and professional agencies happen to be spending so much time to deal with these issues, it really is anticipated that the usage of BIM continues to improve within the AEC marketplace.

In past times facilities administrators had been involved within the building designing procedure in a really constrained way. They executed routine maintenance techniques depending on the as-constructed condition during that time the proprietor takes ownership. BIM patterning might permit facilities administrators to join the project in the foreseeable future much sooner, wherein they could have an impact on the style and engineering. The visual dynamics involving the BIM enables just about all stakeholders to obtain information and facts prior to when the building is finished. This consists of renters, service brokers in addition to routine maintenance… [read more]


Nanotechnology, as Its Name Implies Essay

… Nanotechnology can be used in a wide variety of ways. One of the primary commercial uses of nanotechnology is for polymers. Polymers are used in everyday products such as bumpers and luggage, making them durable and lightweight. Nanotechnology is also used in fabric, and can help make fabrics stain or wrinkle resistant. One use of nanotechnology that most people have experienced in their daily life is the use of protective coatings on glass surfaces to make them glare-resistant. Nanotechnology is also used in health and beauty products such as sunscreens and cleansers. One of the more innovative applications of nanotechnology may be in the food industry, where nano-engineered packages can help improve the longevity of food and nano-manufactured sensors may one day be able to detect food-borne illness (National Nanotechnology Initiative, 2013).

Because nanotechnology is developing at such a rapid pace, it is difficult to truly consider all of the modern advancements in nanotechnology. However, it is widely recognized that the 1981 invention of the scanning tunneling microscope by Gerd Binning and Heinrich Rohrer, which allowed scientists to view individual atoms for the first time, was a breakthrough advance in the field (National Nanotechnology Initiative, 2013). Many of the later advances in nanotechnology focused on discoveries about carbon shape and structure, such as the discovery of the buckyball in 1985, and the discovery of the carbon nanotube in 1991 (National Nanotechnology Initiative, 2013). Another significant advance occurred in 1985, when Don Eigler and Erhard Schweizer demonstrated that they could manipulate individual atoms (National Nanotechnology Initiative, 2013).

Many of the emerging new technologies in nanotechnology seem to integrate multiple scientific disciplines and have health implications. In 2003, " Naomi Halas, Jennifer West, Rebekah Drezek, and Renata Pasqualin at Rice University developed gold nanoshells, which when "tuned" in size to absorb near-infrared light, serve as a platform for the integrated discovery, diagnosis, and treatment of breast cancer without invasive biopsies, surgery, or systemically destructive radiation or chemotherapy" (National Nanotechnology Initiative, 2013). In 2007, scientists used a virus to build a lithium-ion battery (National Nanotechnology Initiative, 2013).

Nanotechnology offers incredible opportunities for science, but could also, like other technologies, have negative applications. In the United States, the use of nanotechnology is governed by the 21st Century Nanotechnology Research and Development Act (P.L. 108-153). In 2004, Britain's Royal Society and Royal Academy of Engineering recognized the potential problems that could arise from the misuse of nanotechnology and called for the government to address those issues. However, at this point in time, there is no international consensus and regulation of nanotechnology.

National Infrastructure Vulnerability Essay

… This is perhaps an over-simplification but this report's length does not allow the author to give the subject justice. Suffice it to say that the management (both IT and non-IT) need to have all procedures and technology current and as cutting-edge as possible and employees need to be hired carefully and trained well so that there is no proverbial egg on the fact if/when a mess is created (UMW, 2013).

IT Security Policy Framework

Establishing an IT security policy that is effective, all-encompassing and proper requires several proverbial "legs" to the stool. A nice offering from tech punditry giant ZDNet offered seven components to an effective IT security policy. Those seven components, in the order in which they were mentioned for the story, were security accountability, network service policies, system policies, physical security, incident handling and response, behavior and acceptable use policies and security training. In short, it's a more drawn out explanation and example of the two broader arenas of counteractions mentioned above, those being user training/handling and they security infrastructure they operate in. The conclusion of the article notes that all of the seven steps mentioned above should be reassessed either quarterly (at a maximum) or at any point in which a configuration change occurs in the IT infrastructure of the firm or agency in question (Taylor, 2001).

Conclusion

In short, there has to be a two-pronged approach with all levels of public and private industry so as to prevent completely preventable data disclosures and other intrusions. Both the private and public sectors have their own responsibilities and callings when discussing this as there are some things that only the private sector can and should do for itself and the same is true of the public sector in the sense of what they must do for themselves for the public betterment as well as what only the government can do for themselves and the private industry.

Security Balance Control Performance and Risk Research Paper

… Security Balance: Control, Performance, And Risk

Describe security principles and objectives and how they relate to the different components of the system-of-systems described in the readings.

System of Systems (SoS) is a concept that "connects the seemingly different parts with the whole to solve large-scale problems" (SoS, 2013, Purdue Engineering). Systems are independent yet are fundamentally connected. A good example of a complex system based upon these principles is that of an airplane. "Many systems…operate various parts of the plane, but the plane flies when all its systems work in tandem and doesn't fly if the systems work independently of each other" (SoS, 2013, Purdue Engineering). From a security perspective, one of the problems with SoS design is that even if the discrete components of the system are secure, when they work in tandem they may not be so and security can become compromised (Waller, Haddock, & Jones 2010:4).

For a system to work optimally there must be a dialogue between the different components. If the whole system or the parts of the interconnecting systems are too secure, conversation between the discrete compartments of the system can be disrupted. Thus, there is always a need to balance security with functionality. Critical components of SoS security include a "boundary check," which means the system has a secure boundary between itself and the outside world; "data flow security" which limits data flow without security measures; "buffer overrun" and "cascade vulnerability," or detecting vulnerabilities when systems are working together (Waller, Haddock, & Jones 2010:14).

Q2. Discuss how the security objectives of confidentiality, integrity, and availability are prioritized in a smart grid environment.

A smart grid is "refers to a class of technology people are using to bring utility electricity delivery systems into the 21st century, using computer-based remote control and automation… smart grid means 'computerizing' the electric utility grid. It includes adding two-way digital communication technology to devices associated with the grid" (Smart grid, 2013, U.S. Department of Energy). This enhances confidentiality because as the network's sensors are continually gathering data, there can be direct two-way communication between the grid and the operating control center, effectively eliminating any 'middleman' in communication and reducing the possibility of impingement by outside sources. Integrity and availability is enhanced because of automation technology as well because the central… [read more]

Regal Marine Product Life Cycle Case Study

… This is because the boats produced by the company must appeal to the customer segments targeted by Regal Marine. In addition to this, Regal Marine is interested in the opinions of dealers and consultants regarding the design of its boats. Customers feel that their opinion is valued by the company, which can significantly increase customer satisfaction. Therefore, it is important to focus on identifying the changing needs of customers in order to develop products that serve their needs and interests. By identifying these needs of customers, Regal Marine can reduce certain risks determined by customers not being interested in the boats the company develops.

3. In its attempt to develop innovative products, Regal Marine uses the Computer Aided Design, CAD, technology. There are several benefits provided by this technology. CAD designs allow the company to reduce the duration of the design stage of its projects. In other words, this technology allows to design boats faster. This means they can be faster produced and commercialized. In addition to this, the technology requires a reduced number of human resources in comparison with traditional drafting techniques that require higher number of employees working on these designs.

The possibility of error can also be reduced in the case of using the CAD technology. This is because the program calculates the variables determined by each design projects. Therefore, the technology allows increased accuracy. It is very important to provide high accuracy in the boats industry. The use of the CAD technology in designing Regal Marine's boats also helps the company establish the performance of the boats it produces. It is important that the company invests in improving the skills of its products.
