scale transmission loss facility for flat lightweight panels. Abstract: The design, construction and qualification of a small-scale sound transmission loss (STL) facility are described. STL measurements were made using the sound intensity technique based on ASTM E 2249-02 [1]. The volume of the irregular-shaped reverberant source chamber was 15 m 3 , and the volume of the regular-shaped anechoi...

The Korean government has strived to secure a disposal site for the safe management of radioactive waste since the early 1980s. The 249 th meeting of the Atomic Energy Commission (AEC) held in September 1998 established the “National Radioactive Waste Management Policy”, which aims at completing the construction of a Low and Intermediate Level Radioactive Waste (LILW) disposal facility by 2008,...

This paper introduces a novel passive suspension system for ground vehicles. This system is based on a flexible Electromagnetic Shock Absorber (EMSA). In the proposed system, efforts are made to a) select a high damping coefficient usable in a car b) determine Physical dimensions and geometry not much different from those of the mechanical shock absorbers and c) seletct EMSA weight and volume l...

This research focuses on the need for preserving fruits in rural areas to prevent waste. The solar drier is made of vital chambers i.e. the concentrator chamber (that harvests the solar irradiance), the transport pipe (that transports the heat generated by convection) and hanger chamber (where the fruits are placed). The temperature within the concentrator chamber and hanger chamber was monitor...

This paper addresses the design of an assembly system facility consisting of multiple assembly lines of different shapes. In such a design problem there are two conflicting objectives: (i) to minimize the overall area of the facility; and (ii) to maximize the efficiency of the material handling transportation system. We first address the optimization problem of objective (ii) when replacing obj...
