Why Consulting Engineers Insurance is Required?

Sunday, August 29th, 2010

Consulting engineer insurance is an exclusive insurance policy in the field of software engineering in order to protect the interests of consulting engineers. Consulting engineers are a kind of consulting software engineer who takes care of the customer’s interests in a team actually building a software system, application or software product.

The role of consulting engineers is pivotal in the long-established field of civil engineering, which term denotes a person who represents the client’s interests with the architects, builders and other suppliers engaged on a construction project.

These expert people generally monitor or overview the working patterns of the construction team. They also ensure the software under development most closely meets the needs of the customer. Consulting software engineers generally get paid by the customer, thus encouraging them to represent the customers’ interests.

Consulting engineers serve people on the basis of their needs and requirements. You can hire them for privately and publicly as you please them to be. Decide about the brief consultations or go for complete design and coordination of a project and bring efficiency into the work. They are often the technical liaison between architects, process specialists, contractors, suppliers and the client.

These people’s specialty include a broad spectrum of software engineering technologies and skills such as design and redesigns in software process; proper analysis; measurement; project and programme management; coding; testing; configuration management; etc.

You may seek general consultation, seek special reports, create reviews of design, estimation of costs, studies of prevailing rates, project monitoring and oversight, patent assistance and preparation of business impact statements.

Engineering is the top earning college major

Sunday, August 29th, 2010

Engineering-related degrees are the top earning college degrees, according to a survey from the National Association of Colleges and Employers. The data was collected by surveying 200 college career centers across the country.

Engineers hold some of the most important jobs in helping the society we live in. “They are in the background designing and building everything from our cell phones, to the buildings we live and work in, to the medical equipment used to improve our lives,” said UNT assistant professor Dr. Althea Arnold.

The top 15 highest earning college degrees:

Petroleum Engineering – $ 83,121 Chemical Engineering – $64,902 Mining Engineering – $64,404 Computer Engineering – $61,738 Computer Science – $61,407 Electrical Engineering – $60,125 Mechanical Engineering – $58,766 Industrial Engineering – $58,358 Systems Engineering – $57,438 Engineering Technology – $56,447 Actuarial Science – $ 56,320 Aeronautical Engineering – $56,311 Agricultural Engineering – $54,352 Biomedical Engineering – $54,158 Construction Management – $53,199

On the list of 15, engineering-related diplomas took every spot except for one, which belonged to actuarial science majors. Actuarial science is the practice of applying mathematical methods to assess risk in financial industries.

“A degree in engineering is certainly an excellent training for innovation and discovery, which contribute significantly to the welfare of mankind,” said Dr. Nourredine Boubekri, Chairman of the Engineering Technology Department at UNT.

The number one degree, petroleum engineering, has an average starting salary of $83, 121. According to CNN, the high salary is an outcome of petroleum’s growing scarcity.

Fewer students are graduating with math-based majors and more are graduating with liberal-arts majors, according to CNN. Out of the 1,524,000 bachelor’s degrees awarded in 2007 only 450 were in petroleum engineering and 4,492 in chemical engineering, according to the National Association of Colleges and Employers. The low number in math-based majors could be a reason why graduates in the field are paid more than others. There are a larger amount of graduates in other fields, making finding employees not very hard.

“I chose to go with liberal arts because I’m not very strong in math, I could never do what engineers do with numbers and calculations,” said UNT junior Kathleen Brown.

Not every student graduating in engineering enters the job market with a huge salary. Engineering has also been hit by the economic and job crises as well, but still students prove to do better with a math/technology based degree in the tough job market.

“I’ve always wanted to study engineering because of my love for math but especially because I love to take things apart and discover what’s going on and how to improve it.” said Mark Logan who hopes to attend UNT in the spring.

The College of Engineering at UNT is made of 3 departments: the departments of computer science and engineering, engineering technology, and materials science and engineering. These departments offer student research and study, giving students the chance of working towards bachelor’s, master’s or doctoral degrees.

“Engineers are the unsung heroes in our advanced technological society,” said Arnold. “Without engineers, no part of our modern society would exist today.”

History of the Diesel Engine

Sunday, August 29th, 2010

The diesel engine has a long history that is intertwined closely with economic and other issues of the time. The diesel engine was created by Rudolph Diesel. He conceptualized the diesel engine and thought up the principle of its operation. He thought up the concept of the engine that compresses air to the degree where there is a resulting rise in temperature.


The concept followed the principle where when the air enters the chamber with the piston the air ignited due to the high temperatures. This causes the piston to move down and eliminates the need for an ignition source. When Diesel designed his engine it was in a time when there was a demand for a more fuel efficient engine as the steam engine was no where close to efficient.


It was on February 27th, 1892 that Diesel filed a patent in the patent office in Germany for his method and design for the combustion engine. He sourced contracts from companies that manufactured machines and began his experimentation stage. During this stage he constructed working models of his design in an attempt to construct the most efficient engine of that time.


It was in the year 1893 that he was successful in putting out the first model that was able to run with its own power and with an efficiency of approximately 26%. This was more than double the efficiency of the steam engines of that time and was a great stride for the efficient engine and a great start to the engines of today.


It was in February of 1897 that he accomplished a great achievement and produced a diesel engine that ran at 75% efficiency. This was the first one of its kind that was deemed suitable for practical use and was demonstrated at the Exhibition fair in France in the year 1898. This engine in particular was run on peanut oil and in Diesel’s vision was great for the small business owners as well as farmers as it used an economical fuel source that was a biomass fuel. It was his use of a biomass fuel that continued until the 1920′s and is starting again today.


In the past the diesel engine was not considered to be small enough for anything but use that was stationary in nature as they were very heavy and cumbersome. Common uses were on ships and industrial uses. Rudolph Diesel disappeared in 1913 and it was not certain whether he died a natural or unnatural death. Many thought his death was related to the politics of the time and the vast knowledge he possessed and was willing to share with enemies of the German government of the time.


In the 1920′s the engine was redesigned into a smaller and more compact version. This allowed it to be used for a wider range of applications and even in the automobile industry. The development of the diesel engine continued and it was made better and better by other inventors such as Clessie L. Cummins who worked out many of the bugs of the diesel engine such as those concerning size and weight as well as the instability of the fuel system.

The True Meaning of Engineering

Friday, August 27th, 2010

If you have ever wondered what engineering is, you may not be prepared for the huge answer that awaits you. When you delve into it, you will actually realize just how global and varied the industry truly is and there are so many career choices you can follow within Engineering.

What is Engineering?

Basically, to put it into simple terms, engineering is where you solve problems. To add a bit more to it, engineers use technical, as well as scientific knowledge in order to make judgments. By using their imaginations, they come up with solutions to problems either new or old.

It is by using the application of technical and scientific knowledge that engineers put judgment, imagination and reasoning to work in order to come up with new solutions to human problems or new ways to solve old problems. So, if that has left you feeling a bit hazy, the best way to summarize all of this is that engineers are problem solvers.

What Are Some Types of Engineering Out There?

To get a better understanding of engineering, it is a good idea to know about some of the types of engineering there is out there. A broad field of engineering is civil engineering and it can be broken down into smaller parts, too.

To get a basic understanding of civil engineering, they deal with the planning, the construction as well as the maintenance of public buildings that are related to water, civilization and even the earth. This can include working with structures such as bridges, water supplies and trains, etc.

Other types of engineering you may or may not have heard of are computer engineering, construction engineering and mechanical engineering. Mechanical engineering is also another broad field of engineering available, and it deals with the physical principles including the analysis, design, manufacture and maintenance of mechanical systems.

Some other types of engineering careers available are aviation, automotive and also software engineering. As you can see, these are just a few that have been mentioned, but every main category can be split up into lots of different fields. If you wanted to be a software engineer, you could consider being a games software engineer or even a communications software engineer. The choice is entirely yours.

Is Engineering for you?

You may be curious about certain things and about the way they work, or you could be someone who loves to solve problems. If this sounds like you and you want to create certain things that could well change the way that everybody lives, engineering could be the absolutely perfect career for you. So, if that does sound like you, why not inquire a little more to see just how you can take the first steps into working as an engineer.

German Engineering, American Vehicle

Thursday, August 26th, 2010

General Motors has done much to revitalize its Saturn brand in the past eighteen months. The brand known in the past as the home of the haggle-free customer service is now the fastest growing brand in the United States auto market. General Motors has revitalized the brand by infusing the Saturn lineup with German engineering.

With the help of Opel, General Motors has turned Saturn vehicles into the most European-ized American cars in the market. The recently named the 2007 North American Car of the Year, the Saturn Aura has close ties with the Opel Vectra. The Saturn Astra that will be released in the North American market later this year is a rebadged Opel Astra. Another result of the collaboration between Opel and Saturn is the convertible Saturn Sky which is based on the Opel GT.

Another Saturn vehicle with European lineage is the midsize crossover SUV Saturn Vue. The vehicle was designed based on the Opel Antara which is based on the General Motors Theta platform. The Antara and the Vue are designed to be indistinguishable from each other. Both are designed and developed in Germany using the country’s engineering.

The similarity between the European Antara and the American Vue is apparent in its handling. The suspension setting of the Antara mirrors that of the Vue. Both crossover SUVs are equipped with strut-front and multilink-rear suspension settings. According to the manufacturer of the Vue, it will have the same handling and stability as its European sibling.

With German engineering behind the new Vue, handling is improved compared to its predecessor. With more responsive handling, the Vue is considered as a near luxury vehicle. In the past, several Saturn auto models have failed to give the brand an upscale feel. But with the partnership with Opel, Saturn vehicles have become a serious competitor in its segment.

The General Motors Theta platform was revised to give the new Vue its sharper handling and better ride comfort. Vibrations and noise from the engine bay are also reduced, thanks to the specially designed Saturn engine mount which absorbs most of the engine’s vibrations.

The revisions to the automobile platform with the use of German engineering have resulted to an increase in weight. More than 400 pounds were added to the new Vue compared to its predecessor. This increase in weight is a surprise considering that the new Vue has virtually the same dimensions as the old Vue.

The 2008 Saturn Vue will be equipped with a standard 2.4-liter Ecotec engine with the variable valve timing. This engine can produce as much as 169 horsepower. An optional engine for the new Vue includes a 3.5-liter V6 with an output of 222 horsepower. Another engine choice available for the Vue is a 3.6-liter direct overhead camshaft V6 engine with an output of 257 horsepower.

The new Saturn Vue will be competing in the North American auto market directly with the Ford Escape, the Honda CR-V and the Toyota RAV4. In order to compete with these already established nameplates, the Saturn Vue has been given European styling which is aimed to attract young vehicle buyers. The changes made in the exterior of the Saturn Vue gives it a sportier look unlike its predecessor. With the help of Opel, it seems that the Saturn Vue will become a major competition for the Asian brands in its segment.

Software Development Process

Wednesday, August 25th, 2010

A software development process is a structure imposed on the development of a software product. Synonyms include software life cycle and software process. There are several models for such processes, each describing approaches to a variety of tasks or activities that take place during the process. . Let us see the steps involve in any software development.

Domain Analysis

Often the first step in attempting to design a new piece of software, whether it be an addition to an existing software, a new application, a new subsystem or a whole new system, is what is generally referred to as “Domain Analysis”. Assuming that the developers (including the analysts) are not sufficiently knowledgeable in the subject area of the new software, the first task is to investigate the so-called “domain” of the software. The more knowledgeable they are about the domain already, the less the work required. Another objective of this work is to make the analysts who will later try to elicit and gather the requirements from the area experts or professionals, speak with them in the domain’s own terminology and to better understand what is being said by these people. Otherwise they will not be taken seriously. So, this phase is an important prelude to extracting and gathering the requirements.

Software Elements Analysis

The most important task in creating a software product is extracting the requirements. Clients typically know what they want, but not what software should do, while incomplete, ambiguous or contradictory requirements are recognized by skilled and experienced software engineers. Frequently demonstrating live code may help reduce the risk that the requirements are incorrect.

Specification

Specification is the task of precisely describing the software to be written, possibly in a rigorous way. In practice, most successful specifications are written to understand and fine-tune applications that were already well-developed, although safety-critical software systems are often carefully specified prior to application development. Specifications are most important for external interfaces that must remain stable.

Implementation (or coding)

Reducing a design to code may be the most obvious part of the software engineering job, but it is not necessarily the largest portion.

Testing

Testing of parts of software, especially where code by two different engineers must work together falls to the software engineer.

Documentation

An important (and often overlooked) task is documenting the internal design of software for the purpose of future maintenance and enhancement. Documentation is most important for external interfaces.

Software Training and Support

A large percentage of software projects fail because the developers fail to realize that it doesn’t matter how much time and planning a development team puts into creating software if nobody in an organization ends up using it. People are occasionally resistant to change and avoid venturing into an unfamiliar area so, as a part of the deployment phase, it is very important to have training classes for the most enthusiastic software users (build excitement and confidence), shifting the training towards the neutral users intermixed with the avid supporters, and finally incorporate the rest of the organization into adopting the new software. Users will have lots of questions and software problems which lead to the next phase of software.

Maintenance

Maintaining and enhancing software to cope with newly discovered problems or new requirements can take far more time than the initial development of the software. Not only may it be necessary to add code that does not fit the original design but just determining how software works at some point after it is completed may require significant effort by a software engineer. About ? of all software engineering work is maintenance, but this statistic can be misleading. A small part of that is fixing bugs. Most maintenance is extending systems to do new things, which in many ways can be considered new work.

Petroleum Engineering Jobs Are In Demand

Monday, August 23rd, 2010

Petroleum engineers are involved in all the stages of oil extraction procedures. From exploration to recovery , petroleum engineers have the skills and ability to supervise the entire operation. Their educational background in chemistry, physics, math, computer science and geology makes them an important part of the extraction and production procedures of oil and gases. On the field they can hold roles as drilling engineers, reservoir engineers, chemical engineers or analysts.

These are some of the jobs and tasks of a petroleum engineer.

1. Planning and Surveys. When a potential oil site is found the initial task of a petroleum engineer is to get samples from the area. The samples will contain information on the quality, quantity and depth of the oil. After analysis of the area and oil are done, the drilling engineer starts planning the extraction process. The right equipment and instruments are chosen for the drilling and extraction of the oil. Positioning the wells and modifying drilling operations are made by the petroleum engineer to increase productivity. The engineer supervises drilling activities on the oilfield and monitors each stage of the operation.

2. Evaluation and Problem Solving. Reservoir engineers have to know how to recover the oil in the ground utilizing the most effective means at a reasonable cost. They consult with geologists, hydrologists, chemical engineers, metallurgical engineers, and mining engineers for design and testing issues. Operational problems have to be addressed so oil recovery procedures can be maximized. Petroleum engineers are tasked with re-evaluating the processes and assist technical personnel by interpreting the results of the evaluation to ensure the changes made will improve oil recovery procedures.

Implementation. Petroleum engineers coordinate and supervise the installation and maintenance of drilling equipment on the oil field. Placement of wells is decided upon and tests are conducted to make sure the process is done according to design. Installation of drilling and other oil recovery equipment have to meet environmental control measures.

Safety at the drilling site is a major concern. It is also the role of petroleum engineers to ensure that machinery and equipment brought on site have been tested to meet performance requirements. Inspections have to be done regularly during recovery procedures to check if safety measures are met. When recovery procedures are over and all the oil or gases have been extracted, it is the job of petroleum engineers to supervise the organized dismantling of structures at the site. The machinery and equipment must be properly removed from the area as well as any waste products that accumulate during extraction procedures. Areas that have been drilled have to be filled and returned to its normal state.

Petroleum engineers have many job tasks while they are out on the field. Their educational background and the skills they acquire on the job provide them with the ability to choose from a broad list of job positions.
