Requirements traceability as being mandated by many standards governing the development of systems (e.g. IEEE/EIA 12207) is undoubtedly useful to software maintenance. To many organizations, it is viewed as a measure of system quality and is treated as an important component of their efforts towards achieving process improvement (CMM). However, not much elaboration on what types of information ...

Ethiopia imports all fuel and crude oils from abroad at high cost, transportation of these fluids has been carried out by using various capacity road heavy-duty truck vehicle. Most tanker accidents happen during turning because the fluid splashing in partially loaded tanks uniqueness carrying liquids. This is a result fact that current baffle configurations are effective reducing sloshing when ...

Hand tool mechanisms designed to reduce the risk factors have rarely been studied. In this paper it is analyze trowel firstly designing in CATIA and then its Finite Element Analysis has been carried out by ABAQUS. The main emphasis is on finding stresses by using this software, then removing them by suitable mechanical working on tool & ergonomic change in the design of handle to make it more c...

Machining of thin-walled (aluminium alloy) aerospace structures is a critical process due to the high warpage. Current practices in the fixture design and the choice of cutting parameters rely solely on conservative guidelines and the designer’s experience. This paper presents evaluation of clamping force to fix the work piecein aVacuum fixture using Vacuum pump. The ISCARonline calculator is u...

The need for vehicle production now is an increase in demand at a lower rate. Customers' expectations terms of longevity, effectiveness, and affordability are increasing tremendously. Automobile wheels constructed alloy aluminium or magnesium metals, occasionally combination the two alloys, known as wheels. Because they lighter than steel wheels, superior to motorcycle driving handling. Overdes...
