What is Automotive Design and Engineering?

The art of designing a car or a truck is nothing short of a miracle.  In this piece I am looking at personal motor vehicles, those that are made with both form and function in mind.  This, to some people, is a very daunting task.  The amount of perfection that people demand in today’s market is almost unfair but somehow all of the engineers and designers can keep up.  People want a vehicle that can reach at least one hundred and thirty miles an hour, zero wind noise, twenty five miles to the gallon minimum, and a sleek attractive body to top it all off.  All the engineers and designers are the people with the amazing minds that create these amazing pieces of art.  What they do is what I want in this piece.  (Fujimoto, 3-24)

            To understand the reason for this paper, you need to know a little bit more about me.  I know this is unconventional but it’s the only way that this paper will make any sense as to why some one would ever want to investigate such a vast field.  Also, why stick to convention if you really want to live.  I am a first year mechanical engineering student at UNC Charlotte.  After I get my bachelors degree in mechanical engineering I hope to get masters in business administration.  With all this work I hope to become the head of automotive design for any car company.  (GM Announces, par.1)

            There is a distinct difference between designers and engineers.  The designers are the people that draw the fancy little pictures of what everyone wants a car to be; big wheels, big engines, and radical lines that could never be made on mass scale for consumer consumption (with today’s technology).  The engineers are the people that take that design and make it doable.  In short the designers are Van Gogh and engineers are Leonardo De Vinci.  Meaning that even though what the designers create is beautiful and simply amazing it has no real purpose and can’t be produced or even function on a custom scale.  Engineers make beautiful things that work like so many of Leonardo De Vinci’s inventions.  (Bob Boniface, par.7)

            There are many aspects of designing a vehicle and designers do play a major part in some of them, mainly in the ascetic aspects of it.  Two of the areas that they have the most say in are the exterior and interior of the car.  But both have to fit the engineer’s numbers for tolerances and so forth.  With the Exterior there are three things that have to be heavily considered besides the obvious safety of passengers and pedestrians and that is aerodynamics, ergonomics, and styling.  Aerodynamics is a highly refined science that vies for position with the other key vehicle design considerations, styling and ergonomics.  (Fujimoto, 223-230)

Early aerodynamics started as more of an art then a science.  Fish were one of the first things to really inspire an aero dynamic design. This is also were the “teardrop” approach evolved from.  But most of the early developments were based on trial and error.  Today there are definite basic principals that every designer and engineer follow to create an aerodynamically efficient vehicle.  Some of the basics are that the underbody should be as smooth as possible.  There should be no sharp angles and the front windscreen should be raked as much as possible.  The front end should start at a low stagnation line and curve up in a continuous line.  That is just a taste of the basic principals but the general idea is to make everything line and contour flow as best it can.  The more interruptions the more drag so if things like door handles and mirrors can flow better or even disappear then designers will jump on it.  (Car Design Online, Aerodynamics, par.1-2)

The interior, unlike aerodynamics, has relatively few things to be held back by.  An interior number one has to fit inside the body of the car and safely hold the passengers in their seats with seat belts and in case of a crash airbags to further protect them.  After that budget and ergonomics are the biggest things that a designer has to worry about.  With an endless list of materials to choose from all with different properties this is one of the biggest factors in designing an interior.  Also one needs to consider how many people can comfortably be sat in the space given.  But ergonomics is not to be forgotten.  People vary dramatically in size and proportion around the world.  And standardizing the production process is the biggest factor of keeping the cost of cars down.  So the main parts of the passenger’s arrangement are adjustable, today more than ever.  Today’s seats can adjust in at least 6 different ways and the streering wheels are no longer just tilting but telescoping as well.  This is were the wheel doesn’t just go up and down like it has but can move in and out to allow the steering wheel to be set to your specific wants.  But things like the gauges and stereo controls are not adjustable in production cars.  In some concept cars they are experimenting with adjustable gauges that would adjust with your height that would be read by a sensor near the sun visor. (Car Design Online, Ergonomics, par. 2-3)

For Engineers there job in creating this vehicle are all the parts that one can’t see but are crucial for the car to work, things such as the engine and transmission.  The engine of the car is an infinitely complex piece of engineering.  Today’s cars, normally, use one of three engines, piston with gas, piston with diesel, or the rotary engine.  The two piston engines are almost exactly the same except for how they combust their fuel.  Gas engines use spark plugs while diesel engines use pure pressure to cause spontaneous combustion.  Though some will use glow plugs (heating element) to help the process along.  Both of these engines have many moving parts that have to work in perfect unison for it to do what it has to do.  Things like springs, belts and pumps can break at any time.  That’s where the rotary motor comes in.  Also known as the Wankel engine after its creator Felix Wankel.  It has an oval like housing with a rounded triangle or epitrochoid shape inside it that rotates around the oval.  It has vastly less moving parts and so is both smaller and lighter.  But it has its disadvantages as well.  While it is more reliable in the short run it wears out much faster then a piston engine and is not as efficient as a piston engine.  So the largest automobile use for this type of engine is for racing but the automobile maker Mazda still has a major investment in personal vehicles with rotary engines.  (Fujimoto, 85-88)

Another unseen component that plays a major part in a vehicles success is the chaise and suspension.  For both there are acceptable variations depending on the application.  The differences for both are directly related.  The Stiffer either the suspension or chaise is the better the vehicle will handle but the worse the ride of the car will feel.  This is because vibrations travel through solids much better then non-solids.  When you have a softer suspension and chaise then the ride will be very comfortable but the body of the car will roll and this shifting weight will throw the handling of the car right out the window.  All of these things are variables that an engineer has to consider when working with the designer to make a great vehicle.  (Fujimoto, 99-105)

To get in this industry where perfection is demanded is not an easy task either.  For the engineers there is a lot of school time involved.  Some have compared getting an engineering degree to pre med for doctors.  With the countless amount of math classes that one has to take just to get his bachelors.  The natural talent that is needed to become an engineer is usually apparent.  Though it is not needed it is usually only those that posses it that make it through all the schooling to a great job.  Most engineers are at least good at math but one of the dead give a ways is the undying need to know how things work.  And to get up to the higher levels of the corporate engineer, like any other job not much helps more then having some good connections.  (GM Announces, par. 2)

With designers it takes a bit less schooling but a lot more natural talent.  The drawings that they have to do for their original design are phenomenal and are almost identical to the end product and have to be.  One example is Bob Boniface he started off his career as an accountant with a Bachelor of Arts degree in psychology and economics from Vanderbilt.  But drew cars in the evenings.  He was eventually talked back into going back to school to College of Creative Studies in Detroit, Michigan and graduated with a bachelor of fine arts. He started at Daimler Chrysler but is now with GM working with Chevrolet concept vehicles.  (Bob Bonifice, par. 1-5)

Another successful designer that I would like to mention, to get an idea of what it takes to become a designer, is Bryan Nesbitt.  His father took him to the campus of the Art Center College of Design in Pasadena, California when he was 12 because he said that he could see his talent.  After studying architecture and industrial design at Georgia Institute of Technology he went to the school that his father took him to and graduated with a Bachelor of Science degree in industrial design.  He also interned at Daimler Chrysler and was later hired by them in 1994 and designed them the PT Cruiser.  In April 2001 he joined General Motors as Chief Designer for Chevrolet. In January 2002, he was appointed Executive Director, Design, Body-Frame Integral Architectures, for all of GM’s North American Brands.  Then in February 2004 was named Executive director of GM Europe Design.  Which means that he is responsible for all Opel, Saab, and Vauxhall design activities.  So as you can see it takes some schooling but a lot of talent.  (Bryan Nesbit, par. 1-10)

When personal motor vehicles first came along back with Henry Ford and others the only way to plan out the design was to draw it out.  There have been many innovations since then.  Some low tech and others mind bogglingly high tech.  One thing that a lot of designers do today well before production is make clay models.  There are several stages to producing a clay model.  First, the scale of the model is determined by using drawings and sketches.  They then make a rig based on these dimensions and they will scale it to be either smaller then the actual size or to the exact actual size of the vehicle.  They put the clay on the form that is part of the rig, a foam core to reduce the amount of the expensive and heavy clay that they have to use.  When it comes to shaping it there used to be only one way to go about it.  That was by hand, manually carving out the model using system of 10-lines. These are the reference points that they use to transfer from the drawings to the model.  From there the designers can either strictly follow their drawings or use templates or they can begin to experiment and develop the form freely.  That’s the beauty of using clay; it can always be reworked and adjusted in tangible form.  (Car Design Online, Modeling, par. 1-3)

In today’s technological world laboring over the clay for weeks is unnecessary.  With today’s technology most of the designing can be done on computers with CAD.  CAD stands for ‘Computer Aided Design.’  These designs done on the computer can give you automatic measurements and can be sent to machines that can recreate them with no manual work.  This technology has even brought clay modeling forward.  Instead of the designers having to carve the entire clay model them selves taking weeks a machine can give the rough out line and then designers can come back and prefect it and change it all they want.  And with the giant leaps with materials they don’t even have to use clay any more to make large three-dimensional models.  After the designers are happy with what the have done in CAD and have made any changes to a clay model and then put that new information into the computer they can make a machine mill down a block of high density foam into a exact replica of the vehicle.  (Car Design Online, Modeling, par. 4)

The Future of design most defiantly lies in computers.  The things we see in the movies are not that far off.  For those who have seen the new movie “Iron man” (2008) when you see him using holograms to make his suit and move it around before he produced it that is a example of were the industry could be in a couple years (Paramount Pictures).  If we ever do reach that point then we may not need to use materials at all before production.  But it’s going to be hard to replace the ability to truly feel what you are working on (Car Design Online, Modeling, par. 4-5).

All of these major tasks have to be completed before a vehicle can even be considered for production.  The way that this paper was worded might have let on that there are only a few people that work on a vehicle at a time but in reality there are full teams of engineers and designers that all have to work one vehicle.  And even with these large teams creating an entirely new vehicle can take years.  And to become one of these few it takes much more then just schooling or talent, it takes determination and patience.  As it does to create one of these works of art.  (Car Body Design, Manufacturing Processes, par. 1-3)

The true importance of this has come painfully apparent over the last couple of months.  The big three of Detroit, General Motors, Ford, and Chrysler, are begging congress to bail them out of their swift fall from being a big as they once were.  This is a perfect example of the free market system; the company with the better product started small but found its way on top of the former big dogs.  I am of course talking about the two big boys from Japan, Toyota and Honda who are now on top of all of Detroit’s big three.  (Fitzgibbons, Patrick, par. 1-2)

There are some very distinct reasons for this.  One of the biggest ones is the rise in energy costs.  The Japanese cars more often then not are more efficient on gas then the American cars.  Also Japan was the first to really capitalize on the Hybrid cars, leaving America to play catch up with their well-established models.  Another big factor was the sub-par quality that was produced back in the 80’s.  The Japanese cars would last a good ten years if you kept the general maintenance up but American cars were falling apart left and right.  (Webster, Larry, par. 2, 5)

That is where I thought that the designers and engineers should have stepped in and made sure that the products that these companies were putting out were any good.  Because now, even though the quality of these cars has stepped up they still carry around the label that their cars are low quality, “Perception trails reality.”  (Webster, Larry, par. 5) For years the Japanese have been making a better product and now the big three are paying for it.  And now they are going to have to do something big to come back to the status that they used to hold, if they can at all.  (Fitzgibbons, Patrick, par. 35)

What it Involves

Distance learning civil engineering involves taking either a Bachelor of Science (B.S.) or a Master of Science (M.S.), in Civil Engineering through the online or distance mode. M.S. in specializations like Structural Engineering, Construction Engineering, Environmental Engineering, Geotechnical Engineering, Transportation Engineering, and Hydraulic Engineering, are also available through distance learning civil engineering.

Though 2-year Associate Degrees are also available, it is only as a bridge to a B.S. Degree, since a Bachelor’s is the minimum entry-level requirement for the industry. However, an Associate Degree in Civil Engineering Technology is acceptable for the career of Civil Engineering Technician.

In the USA, Professional Engineer (PE) license from State Licensing Boards is needed by Civil Engineers if they want to play a role in infrastructure work affecting the public, and the training for the two PE exams, ‘Fundamentals of Engineering’ and ‘Principles and Practice’, are also available through distance learning civil engineering.

Compared with the B.S. degree, there is both more demand as well as options for the M.S. Degree through distance learning civil engineering. The main reason for this is the industry’s increasing demand for specialized civil engineers like Structural or Environmental Engineers. It is also driven by a recent recommendation of the American Society of Civil Engineers (ASCE) to the US State Licensing Boards that the minimum educational qualification for Professional Engineer (PE) license be upgraded from the current Bachelor’s to a Masters level.

Why Civil Engineering?

Unlike many engineering branches, the demand for Civil Engineering has a direct relation with population growth. In fact, this is why Civil Engineering continues to be the largest engineering branch in terms of employment, compared with equally conventional branches like Mechanical Engineering or modern branches like Computer Science, which is mainly due to this direct relation with population growth. More people mean more apartments, and more people also eventually lead to a larger employee pool – thereby increasing both residential and commercial construction.

The demand for Civil Engineering also has a direct correlation with economic growth. This is because, periods of economic slowdown will leave no funds for infrastructure development, while periods of economic growth will provide surplus funds that will be gobbled up in no time by the pending infrastructure needs. In the coming years and decades, economic slowdowns will be better predicted, if not avoided, thanks to the better interventional strategies by institutions like the Federal Reserve. This will leave funds ever available for infrastructure development, and will generate steady demand for Civil Engineers in the coming years.

Most Civil Engineering projects like roads, bridges, tunnels, dams, railway lines, airports, seaports, water supplies, sewage systems, buildings, etc. are also heavy on maintenance and repair, and such regular work contributes to the great demand for Civil Engineers. The need for high-speed, highly-safe mass transportation systems like underground or undersea railways is another major driver for the advancement of Civil Engineering.

Civil Engineering of today is also a professionally satisfying career, with good salaries and technologically updated work. Though average salaries of Civil Engineers are not very high, many of them draw as much as US $95,000 and none of them draw below US $43,500. They also get to work in high-tech areas like earthquake-resistant designs, and make heavy use of tools like Computer Aided Design / Engineering (CAD/CAE).

Why Distance Learning Civil Engineering?

Almost all online or distance courses in any branch of engineering would require work in the industry to meet coursework requirements, as coursework in on-campus labs is not possible. Civil Engineering has the greatest advantage on this front as civil work is abundant everywhere, and this is the main reason why so many Universities and Colleges offer distance learning civil engineering.

It is the best option for technicians, surveyors, and other junior technical staff working in the industry, who want to upgrade themselves to the status of an engineer. Indeed, the majority of those going for a B.S. degree through distance learning civil engineering, are already working in the industry. Practicing Civil Engineers already having a Bachelor’s Degree, also find this the best option, as there is professional pressure on them to specialize further in the field, without upsetting their regular work.

When a Civil Engineer grows from an employee to a Consultant, the Professional Engineer (PE) license will become increasingly important. It is widely expected that soon an M.S. in Civil Engineering would become the minimum educational qualification needed for this, and distance learning civil engineering is the best option for this.

What to Expect From Distance Learning Civil Engineering, in the Future?

As of today, the number of M.S. Degrees in General Civil Engineering is much more than M.S. in the Civil Engineering specializations like Structural, Construction, Environmental, Geotechnical, Transportation, or Hydraulic. However, this scenario will rapidly change, reflecting the increased demand for specialized Civil Engineers. The result will be that Distance Learning Civil Engineering will be offered by more institutions, and that it will be offered with more majors and specializations.

Why Electronics Engineering Technology?

All of today’s booming industrial sectors like telecommunications, medical equipment, control systems, automotive systems, navigational systems, and of course, the consumer appliances sector are bringing out everything from mobile phones to home theatres, and require expertise in Electronics Engineering more than anything else, which explains the demand for Electronics Engineering professionals.

However, to attempt the field through an Engineering Degree can be taxing to those students who are not interested in taking advanced level mathematics (calculus) courses that an Engineering Degree requires, or to endure its long 4-year time frame. For such students, Electronics Engineering Technology is a great option, with its stress on applied or hands-on Electronics Engineering rather than the mathematics-dense and research-oriented Electronics Engineering. The time frame also is much shorter, with an Electronics Engineering Technician requiring only a 2-year Associate Degree to enter the field.

The job opportunities too are tilted in favor of Electronics Engineering Technicians when compared with Electronics Engineers; there are 182,000 Electrical and Electronics Engineering Technicians working in USA, compared with only 143,000 Electronics Engineers. The only drawbacks – a lower level in the hierarchy and the lower starting salaries than Electronics Engineers – can be overcome in the long run, since interested Electronics Engineering Technicians can study further for a 4-year Bachelors Degree, thus qualifying for the senior position of Electronics Engineering Technologist, who enjoys a position and salary comparable to Electronics Engineers. Average salary for Electronics Engineering Senior Technicians / Technologists is US $46,000, very comparable to salaries for Electronics Engineers at US $52,000.

Why Electronics Engineering Technology Distance Learning?

It is estimated that job opportunities for Electronics Engineering Technicians and Technologists would grow at up to 17% every year, for nearly the next 10 years. The requirement of an Associate Degree for entering the field is a relatively recent phenomenon, and a significant percentage of working Electronics Engineering Technicians doesn’t have such a formal degree. The industry preference to degree holders is encouraging such working professionals to get an Associate Degree, and electronics engineering technology distance learning becomes the natural choice. Also, due to the boom in the sector, those already having an Associate Degree will go for a Bachelors Degree so that they can work as a Technologist. And, of course, the growth prospects in the sector are attracting working professionals from other fields to Electronics Engineering Technology. These three factors are driving the huge demand for electronics engineering technology distance learning courses.

Earlier, there were technological hindrances to deliver such a hands-on course through a distance or online model. However, with the development of state-of-the-art systems like National Instruments’ LabVIEW/ELVIS (Educational Laboratory Virtual Instrumentation Suite), which can be used by remote students through a web browser, to virtually perform any electronics experiment, the demand for Electronics Engineering Distance Learning courses are at an all-time high.

Universities and Colleges Offering Electronics Engineering Technology Distance Learning

Electronics engineering technology distance learning courses offer both 2-year Associate and 4-year Bachelors Degrees. While Community Colleges and Institutes dominate the Associate Degree scene, Universities and Polytechnics are the primary sources for Bachelors Degrees. While searching for electronics engineering technology distance learning courses, it should be kept in mind that many US institutions still call the subject Electrical Engineering Technology.

Associate Degrees

Many Community Colleges and Institutes offer 2-year Associate Degrees for electronics engineering technology distance learning, but fully accredited courses are fewer. Whether for employment as an Electronics Engineering Technician or for further pursuance of a Bachelors Degree, it is always better to go for an accredited course. Cleveland Institute of Electronics (CIE), Penn Foster Career School, and Grantham University are three institutions that offer accredited Associate Degrees in the subject.

CIE’s Associate in Applied Science (A.A.S.) in Electronics Engineering Technology boasts of many unique features. Designed from the ground up as a distance learning course, rather than an online adaptation of a regular course, the CIE A.A.S. provides everything that an electronics engineering technology distance learning student might require, in a packaged fashion – complete with printed courseware for over 250 self-paced lessons, videos, and detailed instructions for the over 300 hands-on lab experiments. The only thing missing will be access to an Oscilloscope, and the CIE Bookstore even sells Oscilloscopes at discounted prices to its students! One-to-one instructor support is always available for students. Even the exams can be taken online. A really unique feature of the course is that interested and capable students can complete the course in half or even quarter time, and need only pay for that!

Penn Foster Career School offers an Associate in Specialized Technology (AST) in Electronics Technology, that can be completed fully online, with access to an internet-connected computer being the only requirement. Tuition includes well-written and amply-illustrated printed courseware, tools and equipment for experiments, and unlimited instructor support through website, phone, email, and regular mail. Online open-book exams and end-of-semester proctored exams are other features of this course. The course is self-paced, with longer than 2-year durations allowed.

Grantham University offers an Associate of Science (AS) in Electronics Engineering Technology through the distance mode. The tuition package for the course includes textbooks, lesson guides, grading of all tests, mailing of materials and graded tests from the college, consultation with instructors, and required software. Proctored exams are conducted at the end of every semester, which lend more credibility to this course. Consultation with instructors is available through phone, fax, email, and regular mail. To better facilitate the distance mode of the course, Grantham University even provides a discounted option for its students to buy computers from Dell. However, the main advantage of this course is that full credit transfer is possible to Grantham’s Bachelors Degree in the subject. Grantham is especially popular with military students.

Bachelors Degrees

When it comes to Bachelors Degrees for electronics engineering technology distance learning, even courses with accreditation from the Technology Accreditation Commission (TAC) of the Accreditation Board for Engineering Technology (ABET) are available.

Old Dominion University offers its Bachelor of Science (BS) in Engineering Technology, with Electrical Engineering Technology as Major, and Electrical Systems Technology as optional. The course name follows the earlier US convention of naming Electronics Engineering courses as Electrical Engineering courses. This B.S. indeed has significant stress on Electronics Engineering Technology. In-depth coverage of Electronics includes Linear Electronics, Digital Controls, Microprocessors, Communications, Control Systems etc. High-tech delivery methods like virtual laboratory, streaming video, and satellite broadcast for 1-way video and 2-way audio, are fully utilized. The course is accredited by TAC of ABET.

World College, a wholly owned subsidiary of the Cleveland Institute of Electronics (CIE), offers a Bachelor of Electronics Engineering Technology (BEET) through the distance mode. Features include over 300 lab experiments, online exams, and toll free phones and email for consultation with instructors. Subjects covered include Electronics, Computer Technology, Telecommunications, Electrical Power, and Control Systems. Access to a computer and an oscilloscope are necessary.

Grantham University (described above, under Associate Degrees) also offers a Bachelor of Science (BS) in Electronics Engineering Technology.

The only current limiting factor for electronics engineering technology distance learning seems to be the high costs for implementing virtual labs that can be simultaneously accessed by a large number of students, and once this is solved by better and economical hardware and software, electronics engineering technology distance learning will be provided by more and more Universities, Colleges, and Polytechnic Institutes.

A deceptive process in which crackers “engineer” or design a social situation to trick others into allowing them access to an otherwise closed network, or into believing a reality that does not exist.

However, in a much broader sense, social engineering can indeed take place outside of a technical field or applied to describe a non-I.T. related situation, because in reality, the act essentially involves deceiving another individual into divulging information that should be kept secret.  The following definition better describes social engineering in this light (Social engineering (security), 2009):

Social engineering is the act of manipulating people into performing actions or divulging confidential information. While similar to a confidence trick or simple fraud, the term typically applies to trickery or deception for the purpose of information gathering, fraud or computer system access; in most cases the attacker never comes face-to-face with the victim.

 The goal of this paper aims to explore these many situations that others might not classify as an social engineering act to steal information, and in addition to that goal, explore similar objectives throughout: to create a conversation about social engineering by generating awareness, discuss the many different kinds of social engineering methods, cite examples of real world social engineering events & the people responsible, and finally, cover a list of best practices to avoid social engineering attacks.

        So now that we have established a “working definition” by which to base the foundation of this discussion on social engineering, the next logical step would be to mention a few of the well-known techniques employed in social engineering acts (Granger, 2001). 

A very widely recognized form of social engineering occurs over the phone, which gives all the anonymity in the world a person with malicious intent could ask for.  Those that are particularly vulnerable to this type of threat are help desks, customer service reps, and of course, the common victim: the innocent individual minding their own business at home, on the comfort of their couch.  But just because most of these attacks are known to occur over the phone, does not mean that you are safe when actually using the phone yourself.  What do I mean by this?  IT’s known as shoulder surfing (Dwyer, 2008), or when someone else gleans your PIN number or ATM number by simply standing over your shoulder at either a large airport or phone booth. 

Another great example of why social engineering isn’t just something to worry about at the workplace is how often thieves thrive on another technique known as Dumpster Diving, which involves hackers or anyone with malicious intent attaining information such as: calendars showing when employees might be out of town, policy manuals detailing how internal systems are protected, or even hard drives that can be restored & vital information discovered (Berg, 1995).

But my favorite form of social engineering has to be the form described as Quid Pro Quo.  (Wikipedia, 2009) Imagine, if you will, that the “attacker” attempts to randomly ring up someone claiming to be returning their technical support call; eventually, said attacker will find someone who is grateful to have been called back, who will have no problem following whatever instructions the attack doles out… which will most likely be either a series of malicious commands or the giving up of valuable information (such as a credit card number or name and password).

        While there are certainly many more techniques that could be discussed, I would like to focus the next section on elaborating on the techniques described above with specific, real world scenarios of social engineering taking place.  A very fascinating example of an attacker making the victim believe that he is of a higher authority is described by McAfee Avert Labs and SANS analyst Lennny Zeltser (Kumar, 2009):

Apparently, yellow fliers were placed on vehicles in a parking lot, and the fliers claimed that the vehicles were in violation of parking regulations. The fliers further stated that the owner could visit a certain website to get more information and pictures about the offense.

Now you can imagine the result of this very clever form of social engineering: said victim sees the fliers and once they reach home, attempt to visit the designated website – only to be told to download a toolbar or some other form of disguised malware, which in turn infects their PC with even more malware. 

Kevin Mitnick, who was once one of the most wanted hackers in the U.S. in the late twentieth century, wrote a book entitled The Art of Deception (Mitnick, Amazon, 2009).  In his book, he describes several examples of social engineering, and in one he describes how someone could wait for a snow storm to occur, and then calling the network center posing as a… you guessed it, snowed-in employee.  In other similar examples, Mitnick gives a smaller example of how someone could get a police officer to divulge when he might be out of town, and by scheduling a court date at that specific time; get out of the speeding ticket (Mitnick, Social Engineering Books, 2006).   

        A few of these examples of social engineering are really quite startling.  How can one hope to avoid falling into these tricks when many of them are so clever?  There are a few “best practices” that can be taught which will help falling into the social engineering traps.  Some may be ideal for teaching fellow employees and others might just be applicable to the individual, helping him or her to live a more secure life in regards to their important information’s safety. 

        Some of the best techniques to teach employees, as identified by US-CERT (United States Computer Emergency Readiness Team), are as follows (McDowell, 2004): 

Be suspicious of any phone calls, visits, or email messages from individuals asking about employee or internal information.  Always ask any individual claiming to be of a legitimate organization to verify their claims; this is especially true if they could use your position as a gateway to attain privileged information (for example, you work at a help desk).  Almost never reveal sensitive information over the internet.  Never.  Before doing anything with any amount of sensitive information, consult a higher authority or person with full knowledge of your company’s security policy. Always shred any company documents before discarding them.  Even the slightest bit of information can give an attacker inside knowledge as to who works at the company, their operating hours, or phone numbers.

Richard Steinnon of the website CIO Update decries what is often touted as the “best defense against social engineering:” training.  He stipulates that if you determine a mandatory training in order to sharpen peoples’ awareness is needed in order to avoid social engineering attacks… then you already have a hole in your defenses.  Ultimately, the very best defense against a good social engineering attack is: enforce policy (Stiennon, 2009).

            In conclusion, I have covered a wide ranging of topics all of which involve a discussion centered on Social Engineering.  What began as an initial exploration into the definition of Social Engineering, the discussion then progressed into examples of the varying types of social techniques that attackers employ to trick others into divulging sensitive information. 

Many common examples of real world attacks were also covered and how devastating their implications can be to the victims; corporations or individuals are not safe against any sort of Social Engineering attack.  Chief among those who used to be considered the most dangerous of all, Kevin Mitnick, wrote a book describing in detail how wide-ranging Social Engineering attacks can be. 

And finally, I briefly covered some “best practices” to avoid such social attacks from occurring to you or future employees.  While it may seem obviously to a technically inclined individual, everyone can be a victim of these kinds of attacks when not following the most basic of policies.  Being intelligence with information essentially keeping it to yourself.  But rest assured that there are those out there who are constantly inventing new and dangerous ways in which to trick innocent people into giving away important information.  And it’s only with constant diligence and a re-affirmation to confidentiality can we hope to avoid the trap known as Social Engineering.

Structural steel detailing deals with drawings that are used to determine the requirements for each steel member needed for whatever construction. Structural steel detailing usually has information on specifications, dimensions, sizes, materials needed, and other similar information.

Steel detailing services create an accurate image of each structural element: its placements, connections with other components, and precise dimensions. Steel detailing helps create flawless construction. Structural steel detailing normally starts after the design of the structural framework is done. Using the properties of steel, the steel detail er calculates the forces acting on the connection he is designing. He then consults design tables to arrive at the specific design details of the connection.

For the construction industry, a shop drawing can be confusing. Yet we cannot construct buildings without them! These types of drawings tend to have lots of confusing terms and images. You must have proper professional structural engineering firm to provide good drawing services within your deadline.

Undiscovered mistakes in drawings often leads to unexpected and undesired construction results! This leads to exorbitant economic claims against architects, engineers, and contractors. Some drawings have resulted in expensive construction defects, tragic personal injuries, and the worse of all, loss of life. You have to get this RIGHT!

Outsourcing to a structural engineering firm is the best option! Because the top service providers use the latest technology to provide their clients with the best drawings that exceed their expectations. They need to have a team of professional steel detailer and civil engineers have a track record of providing accurate services according to requirements.

One of the Top Structural Engineering Firm is 7Solutions India. For Information Visit the official site: http://www.7solutionsindia.com/ Free Quotes, and Samples of their business is on there.

What is Mathematics

Mathematics is said to be study of quanities and relations through the use of numbers and symbols.

What is Engineering

Simply Engineering Is the practical application of science to commerce or industry. More complexly while scientist is to know, the engineer to do, that is he brings this knowledge from science to solve practical problems. Engineering also differs from science in that it must take requirements into account including costs, safety, performance and limitations on resources.

History of Engineering

It is assumed that the first engineer was “imhotep” building one of the famous pyramids in 2550 BC. Through out history including the Wonders of the ancient world, exemplify engineering achievements as some of these structures a still standing today. These include the Colleseum, Aqueducts , Pyramids etc.

Areas in Maths and Engineering

The maths and engineering umbrella is very wide and each area is fundamentally important because engineering uses mathematical fundamentals in the calculations of their projects.
