Liquefied Petroleum Gas (LPG) is widely recognized as a safe option for household cooking. However, in settings like Nigeria, within sub-Saharan Africa, hazardous events related to LPG are not uncommon, often resulting from inadequate handling and utilization practices. Despite LPG's growing popularity for its sustainability and efficiency, safety...

When condition-based maintenance (CBM) is combined with proper decision support systems, it leads to enhanced utilization of resources and increased productivity which tends towards business efficiency. The forecasting of the future condition, the remaining operating life, or probability of stable system behavior, based on data from acquired condit...

Soil conditioners like manure and slurry from farmyard and digestate which supply important nutrients to plants are known to contain pathogens that are equally withering to plants. Anaerobic digestion (AD) is an organic or biological process that uses stored energy in organic compounds for biogas production. Ongoing research work has focused on the...

This paper presents the detection of fault prognostics in bearings with the application of extended Takagi-Sugeno fuzzy recursive least square algorithms (extsfrlsa). The nonlinear system is decomposed into a multi-model structure consisting of linear models that are not inherently independent, due to the fuzzy regions defined in extsfrlsa. The ext...

This article focused on the analysis of butt welded joints of a carbon steel pressure vessels reactor under certain conditions to determine a safe operating condition of the system. ANSYS was used to simulate and evaluate the butt welded joints. The welds were analyzed under load, thermal and fluid flow conditions so as to determine the optimum con...

Abstract: A lot of uncertainties and complexities exist in real life problem. Unfortunately, the world approaches such intricate realistic life problems using traditional methods which has failed to offer robust solutions. In recent times, researchers look beyond classical techniques. There is a model shift from the use of classical techniques to t...

Shot peening (SP) is a controlled and systematic process of surface treatment that has a large number of controllable process parameters that make its application highly challenging. It involves the shooting of small and hard metallic balls at a targeted surface, with the aim of enhancing the fatigue strength of the workpiece under unfavorable serv...

The application of shot peening to components and structures induces residual compressive stresses (RCS) on the surface. It has also been identified that fatigue, corrosion fatigue (CF) and stress corrosion cracking (SCC) are lifted by RCS. However, failures still occur in local areas of shot peened components under service conditions at stresses b...

Experimental determination of the effect of annealing on the microstructure and mechanical properties of a cold work 70 - 30 brass, was carried out by subjecting specimens of the material to various degrees of cold-work (20%, 40% and 60%), by straining using a tensile machine. The specimens for each degree of cold work were then annealed at 250 deg...
