The cellular networks are becoming widely used for drone operations under the conditions including long range and beyond- line-of-sight. However, for the countries with many mountain areas and disasters like Japan, the cellular networks sometimes would not be available due to the service area limitation and damages or congestions in their network infrastructure......

Different from the previous conceptual design of configuration synthesis, the main purpose of the configuration synthesis used in the stiffness design is to compare the stiffness performance of different parallel robots. For a class of limbs used in the parallel robots as machining tools, the stiffness performances of different limbs are analyzed, and the comparison results between different limbs are given......

By means of atom probe tomography (APT) and creeping property testing, the affecting of Re/Re on the element’s distribution and creep property of nickel-based single crystal alloy is studied. Results show that the microstructure of alloys consists of cubical y and y phases, and the most of elements Mo, W, Re, Ru, Cr, Co are dissolved in y phase, while the most of Ta, Al, Ni are dissolved in y phase......

Robotic manipulators have positioning problems, speeds, and forces applied on any type of movement. One of the most important activities of industrial robot control is the definition of its movements in three-dimensional space. To perform these movements your joints, need to move and to define these positions in the spaces we need to first calculate the direct kinematics and then the calculation of the literal and numerical inverse kinematics......

The acquisition and processing of EEG and sEMG is an important task in the field of biomechanics. In order to collect bioelectrical signals, new design method of high gain antenna has become a hot topic. This paper proposes a design method of dual-frequency high-gain antenna based on quasi-continuous meta surface. By adding meta surfaces or adding slots to form quasi-continuous meta surfaces to replace the original patch radiating elements, the antenna performance is improved, and new ideas are provided for the realization of high-performance antennas. Based on the theoretical basis of the meta surface to increase the antenna gain, the quasi-continuous meta surface is loaded on the basis of the dual-frequency antenna, which improves the impedance matching of the dual-frequency antenna and at the same time increases the a.....

Renewable energy sources especially wind energy have gained much attention due to the recent energy crisis and the desire to obtain clean energy. Due to vibration, small wind turbines are usually not installed on the structures since the vibration of a wind turbine tower can attain resonance. Resonance is often a contributing factor to many of the vibration problems that occur in wind turbine tower. Small wind turbine exists on National Centre for Energy and Environment, University of Benin with power of 1.0 kW, which creates more vibration on running condition. By reducing vibration in the wind turbine, vibration transformation on the structure will also be avoided so that we can improve performance, lifetime and power quality of wind turbine. Vibration analysis on the small wind turbine model was carried out by perfor..... ReadMore
