This study proposes a generic approach for photogrammetric survey using unmanned aerial vehicle (UAV). UAV is one of the powerful equipment that can be used to obtain the earth surface images from certain altitude. UAV can provide a high quality data for GIS analysis. In this study, two persons are needed; UAV operator and ground crew station. A complete set of fixed wing UAV with autonomous fl...

design models of multi- stage, axial flow compressor are developed for gas turbine engines. axial flow compressor is one of the most important parts of gas turbine units. therefore, its design and performance prediction are very important. one-dimensional modeling is a simple, fast and accurate method for performance prediction of any type of compressors with different geometries. in this appro...

the one-dimensional cutting stock problem, has so many applications in lots of industrial processes and during the past few years has attracted so many researchers’ attention all over the world. in this paper a meta-heuristic method based on aco is presented to solve this problem. in this algorithm, based on designed probabilistic laws, artificial ants do select various cuts and then select the...

an important aspect of microarray studies includes the prediction of patient survival based on their gene expression profile. to deal with the high dimensionality of this data, use of a dimension reduction procedure along with the survival prediction model is necessary. this study aimed to present a new method based on wavelet transform for survival relevant gene selection.the data included 204...

Hypoxia or Oxygen deficiency, contributes significantly to the pathophysiology of many human diseases. High altitude is one such kind of environment where hypoxia is a major stress. The changes in the physiology at high altitude, whether short term or long term, help the successful survival of people from thousands of years. This suggests their adaptation to the adverse environment of high alti...
