Abstract: The main purpose of the project is to evaluate the performance of the boiler and to evaluate the percentage does the boiler accessories involved in improvement of the boiler efficiency, used in the thermal power plant in RINL, and suggested how economically the power is generated by using the by-products available in the Visakhapatnam steel plant. In this report the various benefits and limitations in using the different fuels in the boiler furnace are discussed.

Abstract: The main objective of using jigs and fixtures in an industry is to achieve the Interchangeable Part Concept, and these are mainly used where production of goods is on large scale. The basic elements in the design of indexing type of drill jig is the component model, location, orientation and clamping. The scope of this paper is to design an box type of drill jig for a component having angular holes at 25 deg such the design is validated and verified. The present paper entitled "Design and Analysis of Box type of Drill Jig" is the work done for the design and analysis of Jig. Jigs are mainly used for mass production and for interchangeable parts concept, for a long period in the manufacturing of Jigs. Modeling is done using SOLIDWORKS Software and Analysis by using ANSYS.

Keywords: Design, Interchangeable Part Concept, Jigs, Mass Production

Abstract: This study investigated the effect of add-on-device (side-view mirrors) on the aerodynamic characteristics of a 3-Dimensional Ahmed body using both numerical and experimental methods. It aims at controlling aerodynamic drag on vehicles by determining the optimum mirror position for a simplified vehicle geometry known as Ahmed body model. The rear slant angle of 25° has been used as a benchmark. The geometry is generated in ANSYS '14 design modeler with a single domain of air created surrounding the model after subtracting it from the air enclosure. The turbulent flows around the 3D Ahmed body model was solved using the realizable k-epsilon model with non-equilibrium wall function for near wall treatment with an inlet velocity of 40 m/s. For geometrical optimization, the following were used: distance between the attachment plate and the mirror ranges from 5-20 mm in an............

Abstract: Average annual temperature (1949 – 1976) and (1976 – 2008) and average annual rainfall (1949 – 1976) and (1976 – 2008); for Hydrological Area I {North – Western Nigeria} were analysed by moving averages and trend analysis to determine the trends and impacts of climate variability on water resources of some selected hydrological units of hydrological area I. Time series were performed and the irregular patterns characterised. The observed temperature values have shown an increase of 1.8% while that of the rainfall has increased by 1.2%. The observed maximum values of stream flow discharge in the area were in the year 1989 which coincides with the rise of 1.5% in temperature.........

Abstract: A building is said to have failed when some or part of it cannot perform the function expected of it, which means it has reached a limit stage. This research is focused on the causes, and possible solution to residential building failures in Sokoto State. A total of one hundred and nine (109) Questionnaires were administered to selected professionals in building industry; Architects, Town planners, Civil Engineers, Builders and clients in the study area. Also field study of the area to ascertain the failure of some residential houses in some selected Local Governments of the State was carried out.Primary data were obtained from the analysis of the Questions answered by the respondents using statistical package. The research outcome revealed that 72 experts representing 96%..........
