In this paper, we investigate the social-based recommendation algorithms on heterogeneous social networks and proposed Hete-CF, a social collaborative filtering algorithm using heterogeneous relations. Distinct from the exiting methods, Hete-CF can effectively utilise multiple types of relations in a heterogeneous social network. More importantly, Hete-CF is a general approach and can be used in arbitrary...
By introducing of Compressed Sensing (CS), the computational efficiency of Method of Moments (MoM) can be improved greatly but without significant loss of accuracy. The impact of the construction of underdetermined equation on the possibility of getting accurate recovery solution is analyzed.
In this paper, an automatic speech recognition (ASR) system under ubiquitous environment is proposed, which is successfully implemented in a personalized voice command system under vehicle and living room environment. The proposed ASR system describes a novel scheme of separating speech sources from multi-speakers, detecting speech presence/absence by tracking the higher portion of speech power spectrum...
Direct torque control system of permanent magnet synchronous motor based on second order sliding mode speed controller is introduced to solve the problem that flux linkage and rectangular pulse are both too big in the direct torque control of permanent magnet synchronous motor, it is difficult to control at low speed. This method not only makes the state of system converge in limited time, decreases...
Several parameters influencing the calculation result of bearing capacity are discussed, which indicate bearing capacity coefficient is related to the internal friction angle and length-width ratio of rectangular foundation. Through analyzing ultimate bearing capacity of rectangular foundations using three equations and three theoretical solutions, some useful conclusions are gotten.
We report on a new iterative method for regularizing a nonlinear operator equation in Hilbert spaces. The proposed IIGRA algorithm is combination of nonlinear implicit iterative method and a gradient method for minimizing a modified Tikhonov functional. Under some not very strict assumptions, we will give a convergence result. Finally we present two numerical results for integral equation and parameter...
Present work shows the merits of space vector modulation direct torque control(SVM-DTC) over the conventional direct torque control(conventional DTC). SVM-DTC technique is helpful in solving the basic issues of torque ripple and variable swithing frequency present in the conventional DTC. In order to get the reference voltage vector which is necessary for the SVM-DTC, this paper describes a method...
Power density and heat density of multicore processor system are increasing exponentially with Moore's Law. High temperature on chip greatly affects its reliability, and the cost of packaging and cooling system increases exponentially with power consumption. For a multicore processor, the peak temperature of a block depends on its own power density as well as power density of other blocks on chip...
