aerospace engineering degrees

Aerospace engineering can be studied at the advanced diploma, bachelor's, master's, and Ph.D. levels in aerospace engineering departments at many universities, and in mechanical engineering departments at others. A few departments offer degrees in space-focused astronautical engineering. The Delft University of Technology (TU Delft) in the Netherlands offers one of the top European aerospace educational and research platforms, while the programs of the Massachusetts Institute of Technology and Rutgers University are two such examples.[11] In 2009, U.S. News & World Report ranked the undergraduate aerospace engineering programs at the Massachusetts Institute of Technology, Georgia Institute of Technology, and the University of Michigan as the top three best programs for doctorate granting universities in the United States. The other programs in the top ten were Purdue University, California Institute of Technology, University of Maryland, University of Illinois, Stanford University, University of Texas at Austin, and Virginia Tech in that order.[12] The magazine also rates Embry-Riddle Aeronautical University, the United States Air Force Academy, and the United States Naval Academy as the premier aerospace engineering programs at universities that do not grant doctorate degrees.[13] Wichita State University is renowned for its Aerospace Engineering program and also has the third highest research budget for Aerospace Engineering in the United States.[14][15]
In Canada, the University of Toronto has a quality aerospace engineering program. The aerospace program requires the students to go through a competitive program called engineering science. The academic program in aerospace science and engineering at U of T includes undergraduate and graduate studies. At the graduate level U of T offers research-intensive programs leading to MASc and PhD degrees, and a professionally-oriented program leading to the MEng degree. The scope of U of T's research includes aeronautical engineering (aircraft flight systems, propulsion, aerodynamics, computational fluid dynamics, and structural mechanics) and space systems engineering (spacecraft dynamics and control, space robotics and mechatronics, and microsatellite technology). Carleton University and Ryerson University are other top aerospace engineering universities in Canada which offer accredited graduate and under-graduate degrees.[16][17][18]

In 2002, SUPARCO established IST which is a federally chartered public sector institute of Pakistan offering under graduate and graduate degree in Aerospace Engineering. The MS degree at IST is being offered in collaboration with Beihang University (BUAA), China and Seoul National University, South Korea

aerospace engineering

Aerospace engineering is the branch of engineering behind the design, construction and science of aircraft and spacecraft. It is broken into two major and overlapping branches: aeronautical engineering and astronautical engineering. The former deals with craft that stay within Earth's atmosphere, and the latter deals with craft that operate outside of Earth's atmosphere.
While aeronautical engineering was the original term, the broader "aerospace" has superseded it in usage, as flight technology advanced to include craft operating in outer space.[1] Aerospace engineering, particularly the astronautics branch, is often informally called rocket science.[2][3]

Project engineering

for most engineers not involved at the cutting edge of system design and development, technical work accounts for only a fraction of the work they do. A lot of time is also spent on tasks such as discussing proposals with clients, preparing budgets and determining project schedules. Many senior engineers manage a team of technicians or other engineers and for this reason project management skills are important. Most engineering projects involve some form of documentation and strong written communication skills are therefore very important.
The workplaces of electronics engineers are just as varied as the types of work they do. Electronics engineers may be found in the pristine laboratory environment of a fabrication plant, the offices of a consulting firm or in a research laboratory. During their working life, electronics engineers may find themselves supervising a wide range of individuals including scientists, electricians, computer programmers and other engineers.
Obsolescence of technical skills is a serious concern for electronics engineers. Membership and participation in technical societies, regular reviews of periodicals in the field and a habit of continued learning are therefore essential to maintaining proficiency. And these are mostly used in the field of consumer electronics products.[38]

 

Overview of electronic engineering

Electronic engineering involves the design and testing of electronic circuits that use the electronic properties of components such as resistors, capacitors, inductors, diodes and transistors to achieve a particular functionality.
Signal processing deals with the analysis and manipulation of signals. Signals can be either analog, in which case the signal varies continuously according to the information, or digital, in which case the signal varies according to a series of discrete values representing the information.
For analog signals, signal processing may involve the amplification and filtering of audio signals for audio equipment or the modulation and demodulation of signals for telecommunications. For digital signals, signal processing may involve the compression, error checking and error detection of digital signals.
Telecommunications engineering deals with the transmission of information across a channel such as a co-axial cable, optical fiber or free space.
Transmissions across free space require information to be encoded in a carrier wave in order to shift the information to a carrier frequency suitable for transmission, this is known as modulation. Popular analog modulation techniques include amplitude modulation and frequency modulation. The choice of modulation affects the cost and performance of a system and these two factors must be balanced carefully by the engineer.
Once the transmission characteristics of a system are determined, telecommunication engineers design the transmitters and receivers needed for such systems. These two are sometimes combined to form a two-way communication device known as a transceiver. A key consideration in the design of transmitters is their power consumption as this is closely related to their signal strength. If the signal strength of a transmitter is insufficient the signal's information will be corrupted by noise.
Control engineering has a wide range of applications from the flight and propulsion systems of commercial airplanes to the cruise control present in many modern cars. It also plays an important role in industrial automation.
Control engineers often utilize feedback when designing control systems. For example, in a car with cruise control the vehicle's speed is continuously monitored and fed back to the system which adjusts the engine's power output accordingly. Where there is regular feedback, control theory can be used to determine how the system responds to such feedback.
Instrumentation engineering deals with the design of devices to measure physical quantities such as pressure, flow and temperature. These devices are known as instrumentation.
The design of such instrumentation requires a good understanding of physics that often extends beyond electromagnetic theory. For example, radar guns use the Doppler effect to measure the speed of oncoming vehicles. Similarly, thermocouples use the Peltier-Seebeck effect to measure the temperature difference between two points.
Often instrumentation is not used by itself, but instead as the sensors of larger electrical systems. For example, a thermocouple might be used to help ensure a furnace's temperature remains constant. For this reason, instrumentation engineering is often viewed as the counterpart of control engineering.
Computer engineering deals with the design of computers and computer systems. This may involve the design of new hardware, the design of PDAs or the use of computers to control an industrial plant. Computer engineers may also work on a system's software. However, the design of complex software systems is often the domain of software engineering, which is usually considered a separate discipline.
Desktop computers represent a tiny fraction of the devices a computer engineer might work on, as computer-like architectures are now found in a range of devices including video game consoles and DVD players.

Subfields

Electronic engineering has many subfields. This section describes some of the most popular subfields in electronic engineering; although there are engineers who focus exclusively on one subfield, there are also many who focus on a combination of subfields.

Professional bodies

Professional bodies of note for electrical engineers include the Institute of Electrical and Electronics Engineers (IEEE) and the Institution of Electrical Engineers (IEE) (now renamed the Institution of Engineering and Technology or IET). The IEEE claims to produce 30 percent of the world's literature in electrical/electronic engineering, has over 370,000 members, and holds more than 450 IEEE sponsored or cosponsored conferences worldwide each year.

Education and training

Electronics engineers typically possess an academic degree with a major in electronic engineering. The length of study for such a degree is usually three or four years and the completed degree may be designated as a Bachelor of Engineering, Bachelor of Science, Bachelor of Applied Science, or Bachelor of Technology depending upon the university. Many UK universities also offer Master of Engineering (MEng) degrees at undergraduate level.
The degree generally includes units covering physics, chemistry, mathematics, project management and specific topics in electrical engineering. Initially such topics cover most, if not all, of the subfields of electronic engineering. Students then choose to specialize in one or more subfields towards the end of the degree.
Some electronics engineers also choose to pursue a postgraduate degree such as a Master of Science (MSc), Doctor of Philosophy in Engineering (PhD), or an Engineering Doctorate (EngD). The Master degree is being introduced in some European and American Universities as a first degree and the differentiation of an engineer with graduate and postgraduate studies is often difficult. In these cases, experience is taken into account. The Master's degree may consist of either research, coursework or a mixture of the two. The Doctor of Philosophy consists of a significant research component and is often viewed as the entry point to academia.
In most countries, a Bachelor's degree in engineering represents the first step towards certification and the degree program itself is certified by a professional body. After completing a certified degree program the engineer must satisfy a range of requirements (including work experience requirements) before being certified. Once certified the engineer is designated the title of Professional Engineer (in the United States, Canada and South Africa), Chartered Engineer or Incorporated Engineer (in the United Kingdom, Ireland, India and Zimbabwe), Chartered Professional Engineer (in Australia) or European Engineer (in much of the European Union).
Fundamental to the discipline are the sciences of physics and mathematics as these help to obtain both a qualitative and quantitative description of how such systems will work. Today most engineering work involves the use of computers and it is commonplace to use computer-aided design programs when designing electronic systems. Although most electronic engineers will understand basic circuit theory, the theories employed by engineers generally depend upon the work they do. For example, quantum mechanics and solid state physics might be relevant to an engineer working on VLSI but are largely irrelevant to engineers working with macroscopic electrical systems

Typical electronic engineering undergraduate syllabus

Apart from electromagnetics and network theory, other items in the syllabus are particular to electronics engineering course. Electrical engineering courses have other specialisms such as machines, power generation and distribution. Note that the following list does not include the extensive engineering mathematics curriculum that is a prerequisite to a degree.[21][22

ECLECTRONICS

In the field of electronic engineering, engineers design and test circuits that use the electromagnetic properties of electrical components such as resistors, capacitors, inductors, diodes and transistors to achieve a particular functionality. The tuner circuit, which allows the user of a radio to filter out all but a single station, is just one example of such a circuit.


In designing an integrated circuit, electronics engineers first construct circuit schematics that specify the electrical components and describe the interconnections between them. When completed, VLSI engineers convert the schematics into actual layouts, which map the layers of various conductor and semiconductor materials needed to construct the circuit. The conversion from schematics to layouts can be done by software (see electronic design automation) but very often requires human fine-tuning to decrease space and power consumption. Once the layout is complete, it can be sent to a fabrication plant for manufacturing.

Integrated circuits and other electrical components can then be assembled on printed circuit boards to form more complicated circuits. Today, printed circuit boards are found in most electronic devices including televisions, computers and audio players.[20]

MICRO PROCESSORS

In 1969, Ted Hoff conceived the commercial microprocessor at Intel and thus ignited the development of the personal computer. Hoff's invention was part of an order by a Japanese company for a desktop programmable electronic calculator, which Hoff wanted to build as cheaply as possible. The first realization of the microprocessor was the Intel 4004, a 4-bit processor, in 1969, but only in 1973 did the Intel 8080, an 8-bit processor, make the building of the first personal computer, the MITS Altair 8800, possible. The first PC was announced to the general public on the cover of the January 1975 issue of Popular Electronics.

Many electronics engineers today specialize in the development of programs for microprocessor based electronic systems, known as embedded systems. Due to the detailed knowledge of the hardware that is required for doing this, it is normally done by electronics engineers and not software engineers. Software engineers typically know and use microprocessors only at a conceptual level. Electronics engineers who exclusively carry out the role of programming embedded systems or microprocessors are referred to as "embedded systems engineers", or "firmware engineers".

COMPUTERS

A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format.

Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1] Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into small pocket devices, and can be powered by a small battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous.

The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore computers ranging from a netbook to a supercomputer are all able to perform the same computational tasks, given enough time and storage capacity

RADAR RADIO LOCATONS

During World War II many efforts were expended in the electronic location of enemy targets and aircraft. These included radio beam guidance of bombers, electronic counter measures, early radar systems etc. During this time very little if any effort was expended on consumer electronics developments.[19]

TELEVISON

In 1928 [[Philo Farnsworth]] made the first public demonstration of a purely [[History_of_television#Electronic_television|electronic television]]. During the 1930s several countries began broadcasting, and after World War II it spread to millions of receivers, eventually worldwide. Ever since then, electronics have been fully present in television devices.

Modern televisions and video displays have evolved from bulky electron tube technology to use more compact devices, such as [[Plasma displays|plasma]] and [[LCD display]]s. The trend is for even lower power devices such as the [[organic light-emitting diode]] displays, and it is most likely to replace the LCD and plasma technologies.Joseph Shinar ''Organic Light-Emitting Devices'', p. 45, 2003 ISBN 978-0387953434

VACCUM TUBE DETECTOR

The invention of the triode amplifier, generator, and detector made audio communication by radio practical. (Reginald Fessenden's 1906 transmissions used an electro-mechanical alternator.) The first known radio news program was broadcast 31 August 1920 by station 8MK, the unlicensed predecessor of WWJ (AM) in Detroit, Michigan. Regular wireless broadcasts for entertainment commenced in 1922 from the Marconi Research Centre at Writtle near Chelmsford, England.

While some early radios used some type of amplification through electric current or battery, through the mid 1920s the most common type of receiver was the crystal set. In the 1920s, amplifying vacuum tubes revolutionized both radio receivers and transmitters.

EARLY ELECTRONICS

Electronic engineering as a profession sprang from technological improvements in the telegraph industry in the late 19th century and the radio and the telephone industries in the early 20th century. People were attracted to radio by the technical fascination it inspired, first in receiving and then in transmitting. Many who went into broadcasting in the 1920s were only 'amateurs' in the period before World War I.[9]

The modern discipline of electronic engineering was to a large extent born out of telephone, radio, and television equipment development and the large amount of electronic systems development during World War II of radar, sonar, communication systems, and advanced munitions and weapon systems. In the interwar years, the subject was known as radio engineering and it was only in the late 1950s that the term electronic engineering started to emerge.[10]

The electronic laboratories (Bell Labs in the United States for instance) created and subsidized by large corporations in the industries of radio, television, and telephone equipment began churning out a series of electronic advances. In 1948, came the transistor and in 1960, the IC to revolutionize the electronic industry.[11][12] In the UK, the subject of electronic engineering became distinct from electrical engineering as a university degree subject around 1960. Before this time, students of electronics and related subjects like radio and telecommunications had to enroll in the electrical engineering department of the university as no university had departments of electronics. Electrical engineering was the nearest subject with which electronic engineering could be aligned, although the similarities in subjects covered (except mathematics and electromagnetism) lasted only for the first year of the three-year course

TERMINOLOGY

== Terminology ==
The name [[electrical engineering]] is still used to cover electronic engineering amongst some of the older (notably American and Australian) universities and graduates there are called [[electrical engineers]].Allan R. Hambley ''Electrical Engineering'', pp. 3, 441, Prentice Hall, 2004 ISBN 978-0131470460 Some people believe the term 'electrical engineer' should be reserved for those having specialized in power and heavy current or high voltage engineering, while others believe that power is just one subset of electrical engineering (and indeed the term 'power engineering' is used in that industry) as well as 'electrical distribution engineering'. Again, in recent years there has been a growth of new separate-entry degree courses such as '[[information engineering]]' and '[[communication systems engineering]]', often followed by academic departments of similar name.[http://books.google.com/books?id=X6dEAAAAIAAj&dq=electrical+vs+electronic+engineering&lr= Principles of Electrical Engineering]Anthony J. Pansini ''Electrical Distribution Engineering'', p. xiv, The Fairmont Press Inc., 2006 ISBN 978-0881735468

Most European universities now refer to [[electrical engineering]] as power engineers and make a distinction between Electrical and Electronics Engineering. Beginning in the 1980s, the term [[computer engineer]] was often used to refer to electronic or information engineers. However, Computer Engineering is now considered a subset of Electronics Engineering and the term is now becoming archaic.
Smarajit Ghosh ''Fundamentals of Electrical and Electronic Engineering'', p. xxi, PHI Learning Pvt. Ltd., 2004 ISBN 978-8120323162

ELECTRONIC ENGINEERING

Electronics engineering,[1] also referred to as electronic engineering[2][3] is an engineering discipline which uses the scientific knowledge of the behavior and effects of electrons to develop components, devices, systems, or equipment (as in electron tubes, transistors, integrated circuits, and printed circuit boards) that uses electricity as part of its driving force. Both terms denote a broad engineering field that encompasses many subfields including those that deal with power, instrumentation engineering, telecommunications, semiconductor circuit design, and many others.[4]
The term also covers a large part of electrical engineering degree courses as studied at most European universities. In the U.S., however, electrical engineering encompasses all electrical disciplines including electronics. The Institute of Electrical and Electronics Engineers is one of the most important and influential organizations for electronics engineers.

computer science project

Automatic Meter Reading
Its a tedious job to measure the meter reading of all customers, may it be electricity, water or gas. Someone must be employed to go to each client installation and then take the reading on a book. Then all the collected data must be entered into a computer for processing. AMR is the solution to this problem. AMR or automated meter reading is automating the meter reading process by some means. The ususally used methods are by sending the data over by power lines, or by some wireless means as FM or AM. Here we are suggesting a solution in which we use a GSM modem to communicate the meter reading by either GPRS or SMS. The server identifies the meter by reading the sender Id from where the data or the SMS is coming. The server can prepare the bill automatically by looking at the previous meter readings.

As an additional facility the server can send the bill as SMS to each customer. The server may also cut the supply of those customers who are not paying the bill by issuing control commands.

another projects for computer science

1.People usually changes email addresses and mobile number. Before changing numbers, they will have given that number to many. After changing, when they try, the number will not be correct and hence the call will not be connected. Many contacts are lost in a similar way. The project aims to solve this problem by maintaining an online contact base.
Every contact on the mobile or on the desktop is synced with it. So If Frederik changes his mobile number, every contact who syncs to this database will receive an updated contact information. With this application in place there is no hassle when mobile numbers, emails or address details are changed.
2.
Broadband and advancements in voice technologies are changing the way we used to communicate. Long distance telephone calls are made cheaper by services like skype and Jaxter. The same technology is affecting mobile services also. Most new phones have lots of memory and processing power. And with the data services on mobiles improving, its possible to place internet phone calls via mobiles.
J2me provides a SIP API specifically for this purpose. Using this API an application can be developed that can communicate with any SIP service and that includes most of the web telephony people. The costs will come down for long distance calls. The service can use the wifi facility available on most new generation handsets. Local wifi service can use the internet and also provide a means to make phone calls
3.if you have changed your mobile handset, you have experienced this problem. Transferring contacts can become a messy task . The problem becomes significant when you have too many contacts, more than that you can store in your SIM memory. Other wise you can transfer your contacts to your SIM and change the handset. In such a situation an application that allows to sync your contacts online comes very handy. The idea is to develop an online service and a mobile application that works together.
The mobile application will transfer all the contacts to an online database via GPRS. After changing the handset, the same application can be used to download the contacts back to the mobile again. Regular updations will keep a back up copy of your data online also and prevent from data loss.
4.
Bluetooth is one of the hottest technologies these days. Its a very short range low power communication technology. Almost all handheld devices are now equipped with bluetooth technology. A remote control is a perfect application of bluetooth. Since most mobile phones are bluetooth enabled and programmable via java or symbian, a remote control can be developed in 100% code. The program will connect to bluetooth devices around where the remote server program is running.
The server application can be run on any PC device. We can issue various commands to the device from the bluetooth mobile via the program. We can create different server applications to control various programs on a PC like winamp, media player, powerpoint etc. We can either use java or .net to develop the server program.
5.
The aim of this project is to use open source components to bring the power of wikipedia on you mobile phone. The end output will be like this. If I send “Bill Clinton” from my mobile as SMS to a particular number assigned for this service, I will get a call from the service and Ill be able to hear the wikipedia entry for “Bill clinton” as voice.
The different parts of the project are the SMS pull engine, the wiki search engine, the text to speech converter and the voice application engine. All these components are available open source and free. The text to speech to part can be handled by festival speech recognition engine. The voice call and telephony can be handled by the open source pbx - asterisk.
6.
Land rovers are used in areas where humans cannot reach very easily or cannot operate. Situations like bomb disposal etc are dangerous and can use a land rover very efficiently. But it requires that the land rover be controlled remotely. Wifi can be a good option to control the rover from a remote location. The architecture will consist of a remote stations from where the control signals are initiated.
These signals will be transmitted over the internet to a local wifi relay station, which has got a range of a few 100 meters. The land rover device has got a wifi serial hardware which is capable of picking up the signal from the local wifi terminal and then converting it to serial signals so that the micro controller controlling the land rover can understand it. Its also possible to take pictures and send them back to the control station via the same wifi internet link.
7.Think of the long queues in front of theatres when your favorite movie releases. Those are history now with the latest mobile phone technology. Now a days the mobile penetration is so high that almost everyone capable of spending money for a balcony ticket uses a mobile phone. 
Mobile phone provides us with 3 connectivity options.
Voice
SMS (text)
Data
We can use an IVRS to Book a movie ticket. Or we can send an SMS in a pre defined format or we can use GPRS to access a mobile page and book a ticket. Considering all these the most feasible and cost effective means is to use SMS. All phone models support SMS. Its cheaper than making calls. GPRS requires the network to be sophisticated and the phone must support GPRS.
To book a ticket the user sends a message in a predefined format specifying the show and the number of tickets to a special number. On receiving the SMS our system processes it to see if tickets are available for that particular show and gives a confirmation code to the user. The user can use that code to collect his tickets.

8.Bluetooth is an industrial specification for wireless personal area networks (PANs), also known as IEEE 802.15.1. Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers, digital cameras and video game consoles via a secure, globally unlicensed short-range radio frequency. Bluetooth is a radio standard and communications protocol primarily designed for low power consumption, with a short range (power class dependent: 1 meter, 10 meters, 100 meters) based around low-cost transceiver microchips in each device.
OBEX (abbreviation of OBject EXchange, also termed IrOBEX) is a communications protocol that facilitates the exchange of binary objects between devices. It is maintained by the Infrared Data Association but has also been adopted by the Bluetooth Special Interest Group and the SyncML wing of the OMA. One of OBEX’s earliest popular applications was in the Palm III personal digital assistant. This PDA and its many successors use OBEX to exchange business cards, data, even applications.
The project aims to build an obex layer upon the bluetooth radio so that the device using this protocol can use obex to send/recieve binary/text files.

Bluetooth is an industrial specification for wireless personal area networks (PANs), also known as IEEE 802.15.1. Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers, digital cameras and video game consoles via a secure, globally unlicensed short-range radio frequency. Bluetooth is a radio standard and communications protocol primarily designed for low power consumption, with a short range (power class dependent: 1 meter, 10 meters, 100 meters) based around low-cost transceiver microchips in each device.
 Wi-Fi hot spots are very common now a day. Laptops and PDAs use these hotspots to access the internet as these devices have Wi-Fi facility built into it. But mobile phones do not have Wi-Fi facility in them. Nokia is releasing some models with Wi-Fi, but still those models are costly. But lower end models also come with Bluetooth now. So its a better idea to create a Bluetooth hotspot where Bluetooth mobiles can access the internet.
 With this technology mobile phones need not have a GPRS connection or even a SIM card in it to access the internet. This project has two parts, a client application and a server application. The server application runs in a normal PC with Bluetooth dongle. This PC acts as the gateway to the internet for the mobile. The mobile will host the client application which will connect to the server application in a hotspot environment and provide the mobile with internet access.

Bluetooth technology can be very effectively used for authentication and authorization purposes. Many levels of security are built into Bluetooth technology. We can utilize all of that to provide different levels of security to our car. The car lock control can be hard coded so that it responds to commands received from a single transmitter only. The Bluetooth transmitter is identified by using the hardware address which is unique for each transmitter. Another level of security can be added by using the pass key security in Bluetooth. The user will have to enter a pass code to start the engine ignition. The beauty of using Bluetooth technology lies in the fact that we can use ordinary mobile phones with Bluetooth technology in the place of the transmitter. So in effect the user can control his car doors and ignition from his Bluetooth enabled mobile phone. This technology has got significance since the number of Bluetooth enabled mobile phones are increasing
