A High-frequency and micro-positioning mechanism for the middle-convex and varying ellipse piston machining is developed in this paper. To satisfy the complex profile and high accuracy requirement in piston machining, it uses rolling guide and elastic block to support the linear motor. This mechanism has high rigidity, small damping and high dynamic accuracy. Considering the characteristic of high-frequency...
In this paper, a virtual function signal generator is designed Based on Labview. How to design the generator is introduced in detail. The Virtual Function Signal Generator can generate basic wave such as Sine wave, formula wave, white noise etc. The generator has functions like wave showing and date saving in addition.
To investigate the association of HLA-B*5101 and male Behcet's disease (BD). HLA-B51 antigens and HLA-B51 allele genotyping in 27 BD patients and 53 healthy controls were performed by complement-dependent microlymphocyte toxicity assay, OligoChip and PCR-sequence specific primer (SSP) method. HLA-B51 was found in 63% (17/27) of BD patients and in 15.1% (8/53) of controls < 0.0001, OR = 11.7, 95%...
Window operations which are computationally intensive and data intensive are frequently used in image compression, pattern recognition and digital signal processing. Reconfigurable hardware boards provide a convenient and flexible solution to speed up these algorithms. This paper studies the effect of loop unrolling on the area, clock speed and throughput based on a data schedule method to find the...
