The paper presents a new approach to the radiation Wipes patternreconstruction from near-field amplitude only measurement over a twoplanar scanning surfaces.This new method for antenna patternreconstruction is based on the global optimization PSO (Particle SwarmOptimization).The paper presents appropriate phaseless measurementrequirements and phase
The efficient operation of agricultural machinery depends on the rational organisation of its maintenance.The most systematic research on the technical service of agricultural machinery has been carried out in GosNITI.An integrated maintenance and repair system for agricultural machinery (TORSELHOZ) has been developed.But this system is currently i
Thermal efficiency and power density improvement are the main research foci of the literature on diesel engines.The Miller cycle is considered to be one of the most promising methods of Freezer Knob diesel engine operation.In this study, a fully variable valve timing and lift mechanism (CD-HFVVS) was studied to determine the possibility of a Miller
This paper reports pedagogical experiences and educational techniques in the field of Mechanics of Structures (Mechanical Engineering degree), resorting to computational tools.Several aspects are addressed, covering CAD (Computer-Aided Design) modelling systems to CAE (Computer-Aided Engineering) solutions, in terms of analysis and validation of me
Planarian flatworms are able to both regenerate their whole bodies and continuously adapt their size to nutrient status.Tight control of stem cell proliferation and differentiation during these processes is the key feature of planarian biology.Here we show that the planarian homolog of the phosphoinositide 3-kinase-related kinase (PIKK) family memb
