A new version of the E-Cell simulation system,which runs on Windows as well as Linux, has been released as free software under the terms of the GNU General Public License.

The GNU Multiple Precision Arithmetic Library (GMP) is a widely used library for computing with arbitrary precision arithmetic. has functionally complete bindings many programming languages, including .NET, C++, OCaml, Python, Ruby, and Rust, the notable exception of Java. JGMP provides Java wrappers using GMP from within any JVM-based language. been thoroughly tested benchmarked.

The design and implementation of a Monolithic-Kernel Single Board Computer (SBC) Cubietruck GNU/Linux-like operating system on ARM platform in technical details, including boot loader design UBOOT, building the Kernel uImage, design of root file system and init process. The Single Board Computer Operating System (SBC OS) is developed on Linux platform with GNU tool chain. The SBC OS can be used...

We report on a program for the numerical evaluation of divergent multi-loop integrals. The program is based on iterated sector decomposition. We improve the original algorithm of Binoth and Heinrich such that the program is guaranteed to terminate. The program can be used to compute numerically the Laurent expansion of divergent multi-loop integrals regulated by dimensional regularisation. The ...

When multiplying really large integer operands, the GNU Multiple Precision Arithmetic Library uses a method based on the Fast Fourier Transform. To make an algorithm execute quickly on a modern computer, data has to be available in the cache memory. If that is not the case, a large portion of the execution time will be spent accessing the main memory. It might pay off to perform much extra work...

The fundamental block of WiMAX (Worldwide Interoperability for Microwave Access) PHY layer is Orthogonal Frequency Division Multiplexing (OFDM). The main issue raised in OFDM is high Peak to Average Power Ratio (PAPR) due to multicarrier signal. This paper proposes architecture for PAPR reduction to improve network performance of WiMAX in urban areas where typically Non-Line of sight communicat...

Prolog, abbreviation for PROgrammation en LOGique, was designed in 1972 by Philippe Roussel, Alain Colmerauer at the University of AixMarseille and Robert Kowalski at the University of Edinburgh [1]. Since 1972, Prolog has been one of the most popular logical programming language based on Horn clause logic. Intrigued by the interesting history of Prolog, I decided to learn the nature of the des...

Medium access control (MAC) protocols play a vital role in wireless networking. It is well-known that the high control overhead of IEEE 802.11 MAC is the limiting factor on the throughput and delay performance of wireless networks. In our prior work, three polling service-based MAC protocols (PSMACs) are developed to amortize the high control overhead over multiple frame transmissions, thus ach...

R, a dynamic scripting language designed for statistical computing, has grown in popularity in recent years. However, the low performance of R, due to inefficiencies in the interpretation, limits its usability. Our previous study classifies R programs into three types, including Type I (looping over data), Type II (vector programming), and Type III (glue codes). The most serious performance pro...
