We have developed a new method to estimate no only stress occurrence, but also various workplace stress types. The method relies on adaptive selection of physiological indices integrated into an intelligent multisteps discrimination process. Preliminary results revealed the method promising to improve estimation accuracy of workplace stress types. The study reported here, has two purposes: inve...

This article describes some fundamentals for an environment-responsive traffic control. It starts with a brief description of the needs to consider environmental aspects in urban traffic control, focusing on noise, particular matters (PM), and nitrogen oxides (NOx). Respective current regulations by law in Europe and Germany are explained. Comparing the regulations for the improvement of air qu...

Workflow has been useful in business area for a long time since it helps business process be well defined and be automated. Recently, its use becomes broader and its original model becomes changed. Recent technology such as smart phone and positioning system brings about more dynamic situation to where the workflow can be adopted. The workflow is not routed by the predefined path and condition....

Individuals with Color Vision Deficiency (CVD) are often unable to distinguish between colors that individuals without CVD can distinguish. Recoloring tools exist that modify the colors in an image so they are more easily distinguishable for those with CVD. These tools use models of color differentiation that rely on many assumptions about the environment and user. However, these assumptions ra...

Acid rain still poses a global problem today, exerting many adverse effects on man, animal, and materials. As its research question, the present study tries to find out whether or not acid rains exist in Akure, Nigeria. For so doing, it determines physico-chemical properties of rain water samples, namely pH, temp, Electrical Conductivity (EC), TDS, acidity, SO4-, NO2-, Cl-, and Free CO2. Accord...

this research aims to apply a model to the study and analysis of environmental and natural resource costs created in supply chains of goods and services produced in thailand, and propose indicators for environmental problem management, caused by goods and services production, based on concepts of sustainable production and consumer behavior. the research showed that the highest environmental co...

Among environmental sounds, we have chosen to study a class of action-related impact sounds: automobile door closure sounds. We propose to describe these sounds using a model composed of perceptual properties. The development of the perceptual model was derived from the evaluation of many door closure sounds measured under controlled laboratory listening conditions. However, listening to such s...
