Matrix Theory and Linear Algebra; Probability. Engineers work on control systems ranging from the everyday, passenger-actuated, as those that run an elevator, to the exotic, as systems for keeping spacecraft on course. Control systems are used extensively in aircraft and ships, in military fire-control systems, in power transmission and distribution, in automated manufacturing, and in robotics. Engineers have been working to bring about two revolutionary changes in the field of communications and control: Digital systems are replacing analog ones at the same time that fiber optics are superseding copper cables. Digital systems offer far greater immunity to electrical noise. Fiber optics are likewise immune to interference; they also have tremendous carrying capacity, and are extremely light and inexpensive to manufacture. Virtually unknown just a few decades ago, computer engineering is now among the most rapidly growing fields. The electronics of computers involve engineers in design and manufacture of memory systems, of central processing units, and of peripheral devices ( Computer). Foremost among the avenues now being pursued are the design of Very Large Scale Integration (VLSI) and new computer architectures. The field of computer science is closely related to computer engineering; however, the task of making computers more “intelligent” (artificial intelligence,), through creation of sophisticated programs or development of higher level machine languages or other means, is generally regarded as being in the realm of computer science. One current trend in computer engineering is microminiaturization . Using VLSI, engineers continue to work to squeeze greater and greater numbers of circuit elements onto smaller and smaller chips. Another trend is toward increasing the speed of computer operations through use of parallel processors, superconducting materials, and the like. This branch of engineering includes activities related to the discovery and exploration of mineral deposits and the financing, construction, development, operation, recovery, processing, purification, and marketing of crude minerals and mineral products. The mining engineer is trained in historical geology, mineralogy, paleontology, and geophysics, and employs such tools as the seismograph and the magnetometer for the location of ore or petroleum deposits beneath the surface of the earth ( Petroleum; Seismology). The surveying and drawing of geological maps and sections is an important part of the work of the engineering geologist, who is also responsible for determining whether the geological structure of a given location is suitable for the building of such large structures as dams. Roper Electronic Engineering Ltd have specialised in the design, manufacture and repair of Automatic Voltage Regulators for the last 15 years. Our main business is the manufacture of replacement AVR's for obsolete unit's and those for special applications. In addition to our own range, we also stock a number of other manufacturers models in common use, including those from Newage/Markon, Contrology, Basler, Leroy Somer, Mecc-Alte and Marelli/Ansaldo. We normally hold around 1000 units in stock at any one time for same day despatch, and custom built units can be supplied on short lead times. Our range covers AVR's for small 2 pole generators up to Static Exciters with excitation currents in excess of 100 amps, as well as AVR's for use with high tension machines up to 11Kv. Our designs include both thyristor phase controlled and transistor pulse width modulated types with accessories such as Power Factor Controllers and Diode Failure Indicators. We can also supply AVR's for DC generators. Other spare parts associated with generators, ie Paralleling C/T's, Rotating Diodes, Power Resistors/Rheostats and Volts Trim Potentiometers are also held in stock. Most other manufacturers AVR's can be repaired if not encapsulated, and a service exchange facility can be provided with certain models. With many years of experience in AVR's and generators, and in particular ECC/ECL, we are able to give advice and assistance for any technical problems which may be encountered. Engineering, term applied to the profession in which a knowledge of the mathematical and natural sciences, gained by study, experience, and practice, is applied to the efficient use of the materials and forces of nature. The term engineer properly denotes a person who has received professional training in pure and applied science, but is often loosely used to describe the operator of an engine, as in the terms locomotive engineer, marine engineer, or stationary engineer. In modern terminology these latter occupations are known as crafts or trades. Between the professional engineer and the craftsperson or tradesperson, however, are those individuals known as subprofessionals or paraprofessionals, who apply scientific and engineering skills to technical problems;
