Abstract: To enhance the design of mechanical system, parametric Accelerated Life Testing (ALT) as systematic reliability method suggests to evaluate the design of mechanical systems subjected to repeated stresses. It involves: (1) a parametric ALT plan formed on system BX lifetime, (2) a load examination, (3) a customized parametric ALTs with the design changes, and (4) an assessment of whether the design(s) of product attains the objective BX lifetime. We suggest a general life-stress model and sample size equation. As a test case, based on market data and a customized ALT, the redesign of hinge kit system (HKS) in a refrigerator was investigated. To carry out parametric ALTs, utilizing a force and moment balance analysis, the mechanical impact loading of HKS were computed in operating the refrigerator door. At the first ALT, the HKS failure occurred in the fracture of the kit housing, and oil damper leaked when the HKS broke. The failure modes and mechanisms found in the 1st ALT were alike to

Abstract: Currently sanitary landfills are considered as the only legal disposal methods of municipal waste in Palestine, its number and capacities are limited due to many constrains, that created a strong need for more control over such facilities in order to maintain them functioning properly and mitigate its impact on human beings and environment. Environmental auditing has been introduced in Palestine as a management tool that instruct the operators on how properly manage and operate the landfills to avoid any negative impact on natural resources, human health and surrounding environment. Literature review, visits and onsite evaluation has been conducted to the sanitary landfills in Palestine, in order to be used as a basis for developing “Environmental Auditing Guidelines on Sanitary Landfills in Palestineâ€, and consequently it has become possible to manage solid waste landfills more effectively and efficiently.
