An Active Slot-Ring Antenna (ASRA) has been studied through experiments and analysis in order to find the optimum location of the active device so that the best performance in antenna characteristics is realized in terms of power radiated and power…

A new technique of remote sensing of solar-induced fluorescence and reflectance from vegetation covers  has been developed, radiant calibrated, and applied to investigate solar-induced infrared fluorescence (680-730 nm) and reflectance (750-1000 nm) from some tropical plants within the tropical peak…

In this paper, a review of the techniques available in different categories of audio scrambling schemes is done with respect to Residual Intelligibility. According to Shannon's secure communication theory, for the residual intelligibility to be zero the scrambled signal must…

Wind energy is the environmental free and one of the best renewable energy for generation of electric power. The main aim of the paper is “to produce current using multi generator and single rotor”. This paper proposes multi-generator to address…

Weigher is the necessity of a flour mill either to weigh the clean wheat before 1st break rolls or to weigh the final products to calculate extraction rate.  Low cost automatic weighing machine using latest technology of servo control and…

This study focuses on the use of control factors(volume fraction of fibers (A), aspect ratio of fibers (B) and fibers orientation (C)) to determine the optimum tensile strength of plantain fibers reinforced polyester resin. Tensile tests was conducted on the…

Proper impedance matching of a microstrip patch antenna to the feed line is paramount for efficient radiation. However, impedance matching in such a system is not easy and consequently most systems suffer from return losses. The variation of the input…

Test data have shown that the increase in strength of concrete-filled steel tubular (CFST) columns due to confinement are in variable bigger range than the strength without confinement. Different approaches and design philosophies were adopted in different design codes to…

This study of pressurized water reactor design models involves the application of linear regression analysis on two typical Water-Cooled Nuclear Reactor design models, viz Pressurized Water Reactor Design I (PWRD I) and Pressurized Water Reactor Design II (PWRD II). Empirical…

In this paper, the sawdust briquette machine is designed. Sawmill waste is a big problem especially in urban cities in Nigeria. These wastes are burnt openly which is causing environmental pollution. The wastes can be converted to wealth thereby providing…
