The notion of “important separators” and bounding the number of such separators turned out to be a very useful technique in the design of fixed-parameter tractable algorithms for multi(way) cut problems. For example, the recent breakthrough result of Chen et al. [3] on the Directed Feedback Vertex Set problem can be also explained using this notion. In my talk, I will overview combinatorial and...

The color sorting machines inspect grains by means of digital cameras and remove contaminants by a short burst of compressed air by using the colour difference. This machine has been successfully used in the rice milling industry for long time. Recently color sorters have begun to find their way into durum semolina milling and also into wheat flour mills.The color sorter are used in the wheat c...

Thermal modeling of an automotive cabin was performed in this paper to predict the inside cabin air temperature. To implement this task, thermal and ventilation loads were estimated and the mass and energy balance conservation equations for dry air and water vapor with considering a new parameter (air circulation ratio) as well as the balance equations of internal components of a cabin were de...

AIM To estimate the quantity of dental amalgam that Ontario dentists release into waste water. METHODS Information from a self-administered postal survey of Ontario dentists was combined with the results of other experiments on the weight of amalgam restorations and the quantity of amalgam waste that bypasses solids separators in dental offices. Algorithms were developed to compute the quanti...

The air cargo terminals (ACTs) recently focus on developing relationship with customers to meet their requirements and enhance loyalty in the competitive environments in Taiwan. The purpose of this study is to explore the effects of service quality, innovation capability and corporate image on customer’s satisfaction and loyalty of ACTs. After reviewing the literatures, the structural equation ...

Two challenges for improving the performance of air cathode, single-chamber microbial fuel cells (MFCs) include increasing Coulombic efficiency (CE) and decreasing internal resistance. Nonbiodegradable glass fiber separators between the two electrodes were shown to increase power and CE, compared to cloth separators (J-cloth) that were degraded over time. MFC tests were conducted using glass fi...

Microbial fuel cells (MFC) with 30% wet-proofed air cathodes have previously been optimized to have 4 diffusion layers (DLs) in order to limit oxygen transfer into the anode chamber and optimize performance. Newer MFC designs that allow close electrode spacing have a separator that can also reduce oxygen transfer into the anode chamber, and there are many types of carbon wet-proofed materials a...
