In the recent high speed processor, floating point ALU (FP ALU) is one of the important units to perform the arithmetic and logical functions of the floating point number. Floating point multiplication is one of the arithmetic operations that take more computational time and when implemented in hardware, it requires more area due to the large number of component. However the advantage of implem...

The fundamental property of Fano varieties with mild singularities is that they have a finite polyhedral Mori cone. Thus, it is very interesting to ask: What we can say about algebraic varieties with a finite polyhedral Mori cone? I give a review of known results. All of them were obtained applying methods which were originated in the theory of discrete groups generated by reflections in hyperb...

A new endmember extraction method has been developed that is based on a convex cone model for representing vector data. The endmembers are selected directly from the data set. The algorithm for finding the endmembers is sequential: the convex cone model starts with a single endmember and increases incrementally in dimension. Abundance maps are simultaneously generated and updated at each step. ...

Axonal growth is believed to depend on microtubule transport and microtubule dynamic instability. We now report that the growth of axon collateral branches can occur independent of microtubule dynamic instability and can rely mostly on the transport of preassembled polymer. Raising embryonic sensory neurons in concentrations of either taxol or nocodazole (NOC) that largely inhibit microtubule d...

Offshore wind resources are abundant. Vertical axis turbines (VAWTs) suitable for working in the sea environment because of their low cost and high reliability. In this paper, an offshore floating inverted cone vertical turbine (ICVAWT) is proposed. The 3D unsteady computational fluid dynamics (CFD) method utilized to model ICVAWT. turbulence SST k−ω used solve Navier–Stokes equation, setting p...

Katsevich formula is currently a hot topic for cone-beam computed tomography (CBCT). The filter in the formula can be computed by a regular discrete Hilbert transform (DHT). A configurable single precision floating-point (SPFP) DHT processor is proposed for accelerating the calculation of filter in Katsevich formula. The configurable processor is of memory based architecture with one pipelined ...

Floating roofs are widely used to store petroleum products with high volatility. This is to prevent the product loss and to ensure safe environment around the storage tanks. However, small number of researches were accomplished. These researches aim at study the design of the floating roof and the associated risks that it faces during operation. In an effort to compensate the lack of knowledge ...

A block floating-point (BFP) implementation provides an innovative method of floating-point emulation on a fixed-point processor. This application report implements the BFP algorithm for the Fast Fourier Transform (FFT) algorithm on a Texas Instruments (TI) TMS320C55x DSP by taking advantage of the CPU exponent encoder. The BFP algorithm as it applies to the FFT allows signal gain adjustment i...

We report on a GPU implementation of the condensation method designed by Abdelmalek Salem and Kouachi Said for computing the determinant of a matrix. We consider two types of coefficients: modular integers and floating point numbers. We evaluate the performance of our code by measuring its effective bandwidth and argue that it is numerical stable in the floating point number case. In addition, ...

This paper evaluates the Collective Neuro-Evolution (CONE) method, comparative to a related controller design method, in a simulated multi-robot system. CONE solves collective behavior tasks, and increases task performance via facilitating behavioral specialization. Emergent specialization is guided by genotype and behavioral specialization di erence metrics that regulate genotype recombination...
