  • What is it? RADAR to detect position of objects. Counter measures 1. ECM ( e.g. chaff cartridges) 2. Non ECM. Avoiding detection and innovating deception . RCS reductions, acoustics, thermal and other EM emissions.How is it achieved. Absorbs radar waves or deflects to other directions. Minimizes heat and other emissions from engine and other spots. Makes difficult to detect except closely.Vehicle shape and structure.Smooth edges maximum radio wave reflectors.

  • I've played with many of the commercial content management systems (CMSs) currently on the market, and many have certain qualities or features in common. There is one thing, however, that they all have in common: They are all overpriced. Yes, they have hundreds of features. The fact is that when most Webmasters implement a CMS, they usually don't even come close to using half of the features provided by the CMS. Yes, a few Web sites are exceptions, but most don't need all the features and, unfortunately, they don't have anything available as a substitute, or so they believe.

  • Speech and hearing are closely linked human abilities. It could be said that human speech is optimised toward the frequency ranges that we hear best, or perhaps our hearing is optimised around the frequencies used for speaking. However whichever way we present the argument, it should be clear to an engineer working with speech transmission and processing systems that aspects of both speech and hearing must often be considered together in the field of vocal communications. However, both hearing and speech remain complex subjects in their own right. Hearing particularly so....

  • Another study conducted in a kaolin refinery industry produces hazardous by-product such as Al, Fe, and Zn. In kaolin processing, sulphuric acid is used to improve the whitening (Jordao et al., 2002) is discharged to the river waters. This will influence the well being of aquatic organisms that adapted well at close to neutral pH. Also, in order not to affect the colour and whiteness of paper, impurities such as iron oxides is needed to be removed. This can be made through the reduction of Fe(III) to Fe(II) with metallic Zn. Therefore, Zn, Fe, Al are usually present in the discharge....

  • I started exploring telecommunications’ frontiers at the tender age of nine, way back in 1964. That was the year I visited the New York World’s Fair and found myself, quite unexpectedly, drafted into a corporate public relations demonstration. Back then, nearly all U.S. telecommunications—hardware, software and service—was concentrated in the hands of a giant monopoly—the American Telephone and Telegraph Co. AT&T’s showplace at the fair was the Bell System Pavilion. (Fig. Intro.-1).

  • The milk production system in Pakistan is characterized by large numbers of small, geographically dispersed dairy producers who have marketable surpluses of milk but face diseconomies of scale in marketing it to demand centers in distant urban areas. The traditional middlemen who procure milk from rural areas close to the cities offer at best modest returns to the farmers. In the past couple of decades, two institutional developments have taken place in the milk processing sector.

  • carbon dioxide recovery systems In the fermentation process, the yeast feeds on the wort to produce carbon dioxide and alcohol. This carbon dioxide can be recovered with closed fermentation tanks and used later in the carbonation process. The fermentation process generates about 8-10 lbs/barrel wort (3-4 kg CO2/hl) (Lom and Associates, 1998). Typical CO2 scrubber operations require 2 kg of water per kg of carbon dioxide (Dell, 2001). A large brewery can become self-sufficient for CO2 if a well-designed plant is installed to recover CO2 from fermentation. The U.S.

  • The current control problems present natural trend of increasing its complexity due to performance criteria that is becoming more sophisticated. The necessity of practicers and engineers in dealing with complex dynamic systems has motivated the design of controllers, whose structures are based on multiobjective constraints, knowledge from expert, uncertainties, nonlinearities, parameters that vary with time, time delay conditions, multivariable systems, and others.

  • The hydraulic system consists of an oil sump, one or two oil pumps, an air over oil accumulator tank, and piping to the servomotors. Typically, there are two pumps with lead and lag controls so that there is always a backup pump. Some systems will share two pumps between two units so that in an emergency one pump could be used for both units. The accumulator tank is usually sized so that in the event the pumps fail, the gates can still be closed. The size of the valve required to control the large amount of oil...

  • Notwithstanding the tremendous effort to solve the face recognition problem, it is not possible yet to design a face recognition system with a potential close to human performance. New computer vision and pattern recognition approaches need to be investigated. Even new knowledge and perspectives from different fields like, psychology and neuroscience must be incorporated into the current field of face recognition to design a robust face recognition system.
