The Wingate cycle ergometer test is a widely used test of sustained muscular power. A limitation of the test is the lack of development and retrieval of stored elastic energy due to a lack of an eccentric phase. To measure mechanical power output of the entire stretch-shortening cycle, the test of Bosco et al (1983) was administered to 119 male athletes in 7 different activities during their pr...

StarT-ng is a joint MIT-Motorola project to build a high-performance message passing machine from commercial systems. Each site of the machine consists of a PowerPC 620-based Motorola symmetric multiprocessor (SMP) running the AIX 4.1 operating system. Every processor is connected to a low-latency, high-bandwidth network that is directly accessible from user-level code. In addition to fast mess...

Ng-backmarking with Min-conflict repair, a hybrid algorithm for solving constraint satisfaction problems, is presented in the context of the four main approaches to constraint satisfaction and optimisation: tree-search, domainfiltering, solution repair, and learning while searching. Repair-based techniques are often designed to use local gradients to direct the search for a solution to a constr...

This article deals with the coexistence of two passive optical standards with video transmission using the CATV technology. The paper shows the cross coexistence of standards that are used for an analysis of critical parameters BER. The results of simulations define border parameters for data services in networks with the BER parameter. The designed model has proven that it is able to transfer ...

Cryptocurrencies, based on and led by Bitcoin, have shown promise as infrastructure for pseudonymous online payments, cheap remittance, trustless digital asset exchange, and smart contracts. However, Bitcoin-derived blockchain protocols have inherent scalability limits that trade-off between throughput and latency and withhold the realization of this potential. This paper presents Bitcoin-NG, a...
