In this paper, a novel for high-speed presented. novelty paper the proof concept SynRel machine without Structurally, lamination segments are embedded in an adhesive resin material with high temperature resistance and mechanical strength. Three four-pole have been designed target improving motor torque, compared different ribs configuration. It has shown that proposed...

The interfacial roughness at a buried dielectric–semiconductor interface in an all-polymer field-effect transistor (FET) is characterised by specular neutron reflectivity. Using mixed solvent (toluene–cyclohexane) to deposit poly(9,9-dioctylfluorene-alt-bithiophene) (F8T2) directly on top of poly(methylmethacrylate) (PMMA), we are able fabricate bilayer FET architectures with systematically controlled the polymer–polymer over range approximately 1 3 nm, simply changing ratio. This system has...

A low cost and reliable wafer thinning process for Through Silicon Via (TSV) based three dimensional system in packaging (3D SiP) technology is presented. wafers were first thinned by means of coarse mechanical grinding with a mesh size approximately #325, followed fine #2000. When applying high feed rate to achieve higher material removal during the process, silicon edge crack was observed. It revealed that stress on contacting wheel much larger than those at other locations. Mechanical...

Clustering analysis is an active research branch in the area of data mining due to its simplicity and rapidity. However, K-means algorithm has shortcomings heavily depending on initial clustering center easily falls into local optimum. In this paper, we consider a deep optimization. We put forward first selected algorithm, toward end, novel hybrid based Hybrid Rice Optimization Algorithm were proposed rapidly find optimal cluster centers avoid getting Experimental results show that...

Facing problems with oil production decreasing quickly and water content increasing gradually in S103 well area, the Foam Profile Control was studied on basis of its confirmed agent formula. The facies-controlled geological model area generated using random based Petrel software numerical simulation CMG software. Gas liquid alternating injection pattern optimized as optimal solution through optimization. Two months are cumulative is 0.933 × 107 kg which higher than value subsequent flooding...

In this paper, a bitwise evolutionary genetic algorithm (GA) is proposed to synthesize the power patterns of 4D antenna arrays efficiently. Within binary optimized time sequences arrays, genes 1 and 0 represent switch-on switch-off period antennas, respectively. Gene retention probability, which relates fitness values each individual in whole group, evaluate how good gene is. With crossover operator traditional GA replaced with new method generate next generation. The applied synthesis...

Purpose Recent development of wireless communication devices dictates that miniaturization, multi-functions and high integration are the important factors for antenna structures. This has resulted in requirement antennas with dual or multi-frequency operations. Although dual-band can be achieved through experience-based configuration selection parameter adjustment, it is still a challenging problem to design an specific dual-frequency operations effectively. The purpose paper develop...

Radar sounder technology had been applied to Mars explorations, such as MARSIS (Mars Advanced for Subsurface and Ionosphere Sounding) in 2003 SHARAD (SHAllow RADar) 2005. China is also planning launch the program future. To investigate radar echoes from layered media, we have developed numerical simulation of range at 1-50 MHz rough surface/subsurface model. Furthermore, parameter inversions media. As an example validate these approaches, collect 34 orbits data invert dielectric constant...

Since it was discovered that hippocampus plays a vital role in human memory, enormous investigations on brain memory have been carried out the last few decades. However, so far, there has no report demonstrating how and what form is encoded, stored retrieved. In this paper, we propose holographic model with theoretical analysis to describe mechanism of encoding, storage retrieval brain. The suggests encoding achieved through process hologram generation synapses via interference signal wave...
