In this paper, we present the principal component analysis (PCA) of shape deformations of bilateral hippocampi in Alzheimer's disease (AD) as derived in the large deformation diffeomorphic metric mapping setting. We investigated the PCA patterns (the scores and loadings) of the bilateral hippocampi for 51 subjects, 28 of which had AD while 23 were normal aging. Student's t-tests were used to select...
In this paper, a Central Pattern Generator (CPG) model of a flexor and an extensor is developed, according to the experiments implemented in a crank-rotation task. The drive torque which achieved the arm movement is obtained by six muscles models consisted of outputs of the CPG model. The parameters of CPG model is optimized by minimum torque-change criterion and genetic algorithm. Finally, the simulation...
Nowadays, the GPGPU technology has accelerated many physics-based simulations. SPH (Smoothed Particle Hydrodynamics) is widely used to simulate complex physical phenomena, which using neighbor search as its key procedure. Sorting and grid based method is one of the widely used neighbor search methods on the GPU. This paper presents a new special sorting method to accelerate the neighbor search procedure...
Machine-to-Machine (M2M) communicationsaims to enablemachines to communicate with each other withouthuman intervention. The M2M traffic is quite different from Human-to-Human (H2H) traffic. Discontinuous reception (DRX) isone of the promising technologies for energy saving in LTE-A networks. The existing works on DRX pay more attention to H2H traffic, especially focusing on DRX in RRC active mode...
The long term evolution (LTE) networks provide high data rate access to support multi-media services at the expense of more power consumption in user equipment (UE). Discontinuous reception (DRX) mechanism is one of the promising technologies for energy saving in LTE networks, which extends UE battery lifetime effectively. The DRX parameters configuration should make a compromise between power saving...
This paper addressed the problem of multi-frame image super resolution and implementation to fingerprint image. The use of computers in fingerprints recognition is highly desirable in many applications where security is an important concern. However, as the performance of fingerprint recognition algorithm relies heavily on the quality of the input fingerprint images. it is essential to incorporate...
The detection and restoration of intensity flicker is a common artifact in the restoration of archived film. Considering the interrelation between the successive frames in the image sequences, a novel approach based on motion compensation is proposed. Three steps search algorithm is introduced to estimate motion vectors, which can detect motion regions more accurately. Besides, threshold method is...
