Modelling and Simulation of the Strength Properties of Ultra-High Performance Fiber Reinforced Concrete Specimens

The strength performance of UHPFRC with micro and hooked-ends steel fibers was studied in this paper using Finite Element (FE) modelling and simulation. The specimens were modelled in geometry, material, constraints, load and boundary conditions using ABAQUS package and dynamic explicit analysis was used to to investigate the crack pattern, failure mode and stress-stain behaviour of the UHPFRC specimens when subjected to uniaxial compression and tension loading. Results from the FE simulation...

Study of Thermal and Tensile Properties of the Thermoset Polymer

ABSTRACT Current advancement in raw material utilization is gradually changing from the conventional petro-based materials into natural materials in order to arrest environmental pollution issue which arises as a result of the non-biodegradability of products obtained from petro-based resources. Plant oil among other alternatives due to its abundance, relatively low cost, non-toxicity and biodegradable nature have been found to be a potential replacement for petro-based feedstock in many in...

Defect Analysis and Productivity Enhancement of Crankcase Casting through Pareto Analysis, POKAYOKE and QC Tools

Abstract: Productivity is a very important aspect in any organization. Productivity means output obtained with respect to how much input is provided. To increase the productivity of any organization it is necessary to study and analyze the rejection data of that organization. This research focuses on the need of following a proper methodology in solving any particular problem. The defects were prioritized using QC tools, Pareto analysis. This research emphasizes on the importance of focusing ...

Will Fiscal Decentralization Stimulate Energy Demand? Evidence From Kenya

This study set out to estimate empirically the effects of fiscal decentralization on energy demand in Kenyan counties, 2013-2017. The finding of this study has established the critical role of decentralization in positively influencing electricity demand at the sub-national level through improved energy efficiency, rises in energy innovation and involving local actors in energy planning processes. This has been qualified by the ability of decentralization to provide necessary economic and fin...

Resilient microgrids designed for power system

Resilient microgrids are being used more frequently to improve the flexibility, resilience, coordinated energy management capabilities, self-sufficiency, and overall reliability of power systems. Power electronics improvements, enhanced control systems, reducing costs, and broad adoption of distributed energy generating technologies like solar photovoltaics and storage are driving this major industry expansion. Microgrids provide backup power sources during grid failures, ensuring resilience ...

Reliability Analysis of Continuous Beam Using Hasofer-Lind Reliability Method

This project work “Reliability analysis of a continuous beam using Hasofer-Lind Reliability Method” was primarily concerned with the effect of varying parameters such as load, modulus of elasticity, moment of inertia and span length on the reliability of a continuous beam. The limit state considered is deflection, and the allowable deflection is specified as L/360. The maximum deflection is 0.0069wL^4/EI and it occurs at 0.446L from either end (AISC, 1986). Reliability analysis, expre...

Basic Principle of Machining and Arc Welding

ABSTRACT This project tittle ‘’basic principle of machining’’ deal with the operations on lathe, milling and some part of arc welding, turning, taper turning, threading, knurling and chamfering, while on milling machine spur Gears were cut, forming a hexagon shape and square shape were all done on milling machine. A simple component/part which contained all the above mention operation were produced in one work piece. In conclusion we are able to produce spurs gears, square thread, an...

Design and Construction of a 4 Way Inter-Communication System

ABSTRACT An intercom is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network. Intercoms are generally mounted permanently in buildings and vehicles. Intercoms can incorporate connections to public address loudspeaker systems, walkie talkies, telephones. Four-way intercommunication system is nothing but the communication within four persons not close to one another. This does not mean w...

Influence of Solar-Exhaust Gas Greenhouse Drying Modes on Viability of Black Nightshade Seeds

In this study, three distinct and unique modes of greenhouse drying are introduced: solar, solar-exhaust gas, and exhaust gas modes of drying. The effect of drying black nightshade seeds in the three modes was studied, using germinability as a measure of quality. In solar mode, seeds were dried from a moisture content of 89.34% (db) to 7.13% (db) with the greenhouse dryer room air temperature range of 14.82-58.46°C and relative humidity of 9.40-88.03%. In solar-exhaust gas mode drying was pe...

Evaluation of Thin Layer Models for Simulating Drying Kinetics of Black Nightshade Seeds in a Solar-Exhaust Gas Greenhouse Dryer

Abstract: The current study aimed to use, besides solar, waste heat from exhaust gas of a diesel engine operated for milling of grain, to dry black nightshade seeds. Assessment of thin layer models for simulating drying kinetics of black nightshade seeds was performed in a solar-exhaust gas greenhouse dryer operated on solar; solar-exhaust gas; and exhaust gas modes. In solar mode, seeds took 11 hours to reach a final moisture content of 7.13% (db) from an initial one of 89.34% (db). In solar...

Performance Assessment of Hybrid Recuperative Heat Exchanger for Diesel Engine Generated Exhausted Gas

Abstract: In this study, the use of supplemental heat energy from exhaust gas of a stationary diesel engine was assessed to explore a new method of drying black nightshade seeds in a solar-exhaust gas greenhouse dryer. The energy recovery potential of a hybrid recuperative heat exchanger (HRHE) was demonstrated with the objective of utilizing the recovered energy from an engine on milling operations to heat a fluid stream of drying air. The results show that 4.45 kW of thermal energy was avai...

Design and Development of a Hybrid Bicycle

This project involved the conversion of a conventional bicycle into an electric hybrid bicycle using a hub motor, battery, controller, throttle, and battery indicator. The selection of a flywheel-based regenerative mechanism was justified based on its superior energy storage capabilities. The challenges faced during the assembly, including bearing and clutch drive iterations, were overcome through the use of multiple bearings, metal casting, and welding. The implementation of an indirect...
