The urban micro climate is important for the well-being of citizens. With simulation models the urban micro climate can be studied and recommendations can be made to improve the micro climatic situation. However, mainly synthetic scenarios are simulated due to a lack of information. The objective of this paper is to explore the potential of airborne hyperspectral and height data to provide area...

Received Feb 19, 2013 Revised Aug 13, 2013 Accepted Aug 29, 2013 This paper focuses on precision automated pushing of multiple micro objects. An adaptive control system is proposed to accurately push and position the micro objects on a substrate. Each micro object exhibits different characteristics in terms of the surface micro forces governing the manipulation process. The controller is design...

In this work, we analyze the thermodynamics and geometric optimization of thermoelectric elements in a hybrid two-stage thermoelectric micro cooler (TEMC). We propose a novel procedure to improve the performance of the micro cooler based on optimum geometric parameters, cross sectional area (A) and length (L), of the semiconductor elements. Our analysis takes into account the Thomson effect to ...

Micromachining is the most basic technology for the production of miniaturized parts and components. Micro turning is one type of micromachining process which uses a solid tool and its material removal process is almost similar to conventional turning operation. The objective of this paper is to provide a state of the art in the field of micro turning. In recent years, researchers have explored...

Lack of knowledge on soil geotechnical properties can cause many problems in the construction and maintenance of irrigation and drainage networks. In general, all of unconventional soils such as gypsiferous soils can cause some problems to irrigation canals. Some studies have been conducted on a variety of problematic soils, but still there is a need for more research activities and field studi...

Introduction: Considering high prevalence of epileptic disease and considering that 40 percent of epileptic patients are resistant to drug therapy, it needs more researches to find new therapeutic ways. LFS is among the new methods for epilepsy treatments. One possible mechanism involved in the anticonvulsant effect of LFS is increased adenosine. Therefore, in this study the role of adenosine p...
