INTRODUCTION Digital systems design teams are facing exponentially growing complexities and need processes and tools that reduce the time needed to gain insight into difficult system integration problems. A digital system is a data technology that uses discrete (discontinuous) values. By contrast, non-digital (or analog) systems use a continuous range of values to represent information. Although digital representations are discrete, the information represented can be either discrete, suc...

This is a paper about generating sequences with matlab A digital signal processor (DSP) is a specialized microprocessor (or a SIP block), with its architecture optimized for the operational needs of digital signal processing. The goal of DSPs is usually to measure, filter and/or compress continuous real-world analog signals.1.1Generation of Discrete Time SequencesProject 1.1: Delayed Unit Sample SequenceA unit sample sequence is a sequence that has a value of one (1) at n=0, and a value of ze...
ABSTRACTOil spillage which can simply be referred to as the release of oil into the environment (land or water) either through a deliberate act, accident or as a result of equipment failure indeed has an alarming effect on the affected communities due to the fact that it either renders the environmentuseless or sometimes take a longer time for the affected area to have a natural process of attenuation.In addition, having given the necessary compensation to the affected communities in line wit...
ABSTRACTThe rapid increase in energy consumption particularly in the past several decades has raised fears of exhausting the globe’s reserves of petroleum and other resources in the near future. The huge consumption of fossil fuels has caused visible damage to the environment in various forms. Approximately 90% of our energy consumption comes from fossil fuels. Due to industrializations and population growth our economy and technologies today largely depend upon natural resources, which are...
ABSTRACTEnergy conversion engineering (or heat-power engineering, as it was called prior to the Second World War), has been one of the central themes in the development of the engineering profession. It is concerned with the transformation of energy from sources such as fossil and nuclear fuels and the sun into conveniently used forms such as electrical energy, rotational and propulsive energy, and heating and cooling. A multitude of choices and challenges face the modern energy conversioneng...
ABSTRACTThis report is intended for a general insight into cryogenics. Different individuals may have faint ideas about what cryogenics are as much is not known here in Nigeria about what cryogenics are and this report work clearly gave a deeper knowledge of cryogenics Chapter one gives a brief history of cryogenics and the various cryogenic temperatures that have been achieved since 1800 to 1965. Chapter two gives a general knowledge of the fundamentals of cryogenic engineering...
ABSTRACT This technology is so helpful in our everyday life. This paper dealt extensively about the latest technology which is useful for finishing materials with a very high precision. These latest processes are known as Advanced Fine Finishing Processes. In this paper, we gave a thorough insight into some of these processes. With the demand of stringent technological and functional requirements of the parts from micro- to nano-meter range, evolution of ultra-precision finishing processes ...
ABSTRACT In recent times, most of the household appliances are using electric power and as such, electricity shortage has become a major problem throughout the world. Ceiling fan is one of such appliances that consume electric power. The best way to minimize the power consumption of the ceiling fan is to reduce the weight of the ceiling fan blade. Thus, this project work entails the design of a new ceiling fan blade in which case the weight and power consumption was compared to the Panasonic ...
DEFINITION OF A KEY A key is a piece of steel in inserted between the shaft and a hub of the pulley or the gear, mainly to that power. Key are always inserted parallet to the shaft axis. They are need as temporally fastening and are subjected to considerable cursing and shearing stresses. A key - way in a slut or recess in the shaft and hub of a pulley to accommodate a key. KEYS A key is a machine member employed at the interface of a pair of mating male and female circular cross-secti...
INTRODUCTION This section briefly describes the main features of pumps and pumping systems. What are pumps and pumping systems? Pumping systems account for nearly 20% of the world’s electrical energy demand and range from 25-50% of the energy usage in certain industrial plant operations (US DOE, 2004). Pumps have two main purposes: 1. Transfer of liquid from one place to another place (e.g. water from an underground aquifer into a water storage tank) 2. Circulate liquid around a system ...
ABSTRACT The technical report presented below is based on the design of mechanism that can be used to open and shut the windows of mechanical engineering workshop from ground level .this mechanism was designed in order to improve safety and convince in their workshop .in the report, the design analysis were made and materials were selected based on operating conditions of each component. The material of the tilt and turn mechanism is cast iron while the material of the lever (handle) is stain...
ABSTRACT In a developing economy like Nigeria financial resources are scarce commodity. Hence, cheaper means of accomplishing tasks even within the presence of scarce resources are always explored. This paper presents the design and implementation of a software intercom on local area network (LAN). The design provides a solution that eliminates the use of expensive hard-wired intercoms and Private Automatic Branch Exchange (PABX) by making use of only LAN and full multimedia computer allowing...
ABSTRACT The ambient temperature of tropical countries like Nigeria is as high as 40oC during the dry season. This ultimately gives rise to increase in demand for ice which is used to reduce the temperature of water, soft-drinks as well as other uses. This increase in demand for ice block makes the design and construction of a machine which can be used for the production of ice within a short period of time in order to save energy and time imperative and a worthwhile venture. This paper prese...
