the aim of this study was to investigate the effect of the addition of commercial lipase in various forms on the acceleration of the ripening of uf-feta cheese. commercial lipase from aspergillus niger was encapsulated by using silica composition based on sol-gel method. lipase was then added to cheeses in three forms, namely, free lipase, encapsulated lipase, and encapsulated lipase with arabi...

the synthesis of the title compound is described. deprotection of cis(n-trityl-3-azido-4-styryl)-2-azetidinone to cis-(3-azido-4-styryl)-2-azetidinone was found to be accelerated by the special salt effect under acidic condition

Numerical evaluation of the overlap Dirac operator is difficult since it contains the sign function e(Hw) of the Hermitian Wilson-Dirac operator Hw with a negative mass term. The problems are due to Hw having very small eigenvalues on the equilibrium background configurations generated in current day Monte Carlo simulations. Since these are a consequence of the lattice discretization and do not...

This work investigates hardware acceleration of object tracking by parallelising an algorithm for object classification involving decision trees. Object tracking is the process of recognizing and locating a particular moving object in the spatial as well as in the temporal domain of a video stream. One key application of object tracking is video surveillance, to provide an operator in a control...

In recent technology developments General Purpose computation on Graphics Processor Units (GPGPU) has been recognized a viable HPC technique. In this context, GPUacceleration is rooted in high-order Single Instruction Multiple Data (SIMD)/Single Instruction Multiple Thread (SIMT) vector-processing capability, combined with highspeed asynchronous I/O and sophisticated parallel cache memory archi...

A systematic development of higher order spectral analysis, introduced by Dellwo and Friedman, is undertaken in the framework of an appropriate product space. Accelerated analogues of Osborn’s results about spectral approximation are presented. Numerical examples are given by considering an integral operator.

Policy gradient methods are widely used in reinforcement learning algorithms to search for better policies in the parameterized policy space. They do gradient search in the policy space and are known to converge very slowly. Nesterov developed an accelerated gradient search algorithm for convex optimization problems. This has been recently extended for non-convex and also stochastic optimizatio...

In this paper, we propose and analyze an accelerated linearized Bregman (ALB) method for solving the basis pursuit and related sparse optimization problems. This accelerated algorithm is based on the fact that the linearized Bregman (LB) algorithm is equivalent to a gradient descent method applied to a certain dual formulation. We show that the LB method requires O(1/ε) iterations to obtain an ...

Fast corner detector algorithms are important for achieving real time in different computer vision applications. In this paper, we present new algorithm implementations for corner detection that makes use of the graphics processing units (GPU) of commodity hardware. The programmable capabilities of modern GPUs make it possible to speed up counterpart CPU algorithms. For corner detector algorith...
