Disposal of waste electrical and electronic equipment: A household survey of past behaviors and future preferences in Thailand

Households play a crucial role in the management of waste electrical and electronic equipment (WEEE). As waste generators, their decisions at the point of disposal hold a key to a success of WEEE collection. This article presents main findings from a national survey in Thailand about the reported disposal behaviors in the past and the stated disposal preferences in the future. The survey covered t

Implementation Issues for acoustic echo cancellers

The high computational complexity of acoustic echo cancellation algorithms requires application specific implementations to sustain real time signal processing with affordable power consumption. This is especially true for systems where a delayless approach is considered important, e.g. wireless communication systems. The proposed paper presents architectural considerations to reach a feasible har

Test Cost Modeling for 3D Stacked Chips with Through-Silicon Vias

In this paper we have proposed a test cost model for core-based 3D Stacked ICs (SICs) connected by Through Silicon Vias (TSVs). Unlike in the case of non-stacked chips, where the test flow is well defined by applying the same test schedule both at wafer sort and at package test, the most cost-efficient test flow for 3D TSV-SICs is yet undefined. Therefore, analysing the various alternatives of tes

Experimental test-bench development using force control with industrial robots for the analysis of the mechanical response in car seats

Modern safe and high-quality products not only need to have desired properties in terms of geometry, material, features, etc. from a position-interaction point of view. Also compliance, deflection, impact and safety features depending on force-interacting properties are of (increasing) importance. As a key such example, the mechanical response of car seats has been studied, including the contact f
