hydrogen as an ideal energy carrier can play a very important role in future energy systems for hydro-gen production can be used a variety of technologies and sources. one of the most promising methods for large-scale hydrogen production is thermo-chemical water decomposition using heat energy from nuclear, solar and other sources. the water splitting thermo-chemicals cycles are processes where...

This work focuses on the evaluation of goethite as a catalyst for transformation sulfuric acid into sulfur dioxide, reaction with great interest hybrid electrochemical-thermoelectrochemical Westinghouse cycle hydrogen production. A comparison performance that CuO, Fe2O3, and SiC has been carried out. Moreover, mixture those catalysts was evaluated. The results demonstrate can be used thermal de...

Workers play a crucial role in company, and their workload significantly influences productivity. This research was conducted manufacturing specifically the Warehouse Department (storage section), due to indications of low The objective analyze profiles workers storage section company’s warehouse. analysis using Westinghouse method, which considers skill, effort, condition, consistency analyzin...

One of the most important subjects within the time study activities is tempo rating. Determining the accurate tempo for the workers plays an important role for determining the normal time of the work. There are various methods for determining the pace. One of the basic ones is the Westinghouse method based on four factors that are used while regarding the performance of the operator; skill, eff...

A digital signal processor (DSP) solution is proposed to control an H-bridge DC-DC isolated output power converter. The multiple mode digital controller is evaluated with an existing Westinghouse 1-kW power stage. The digital controller was developed using the dSPACE [1] rapid prototype development system and MATLAB/Simulink. It is evaluated using a real-time digital control development platfor...

This paper focuses on technological discontinuities and late shakeouts in mature industries. The empirical case is combined-cycle gas turbine technology in the power generation industry, where two of four main incumbents (GE, ABB, Siemens and Westinghouse) exited the industry after several years of competition. We show that the vast differences in firm performance are strongly related to variat...

A few years ago Westinghouse innovations in PWR technology resulted a proposal for new type of integral fuel burnable absorbers containing Gadolinium. Preliminary designs loading patterns NPP Krško were made 18 month cycles with standard VANTAGE+ Integral Fuel Burnable Absorbers (IFBA) enriched Boron, as well newly proposed Gadolinium based absorbers. In this paper we investigate the possibilit...

Computational Fluid Dynamics (CFD) has been widely used in pressure drop/hydraulic loss calculations in many industries, including the aerospace and turbo-machinery industry as well as in the nuclear power industry. During the past 30 years, a significant amount of time and effort have been spent in benchmarking the CFD tools and models against test data in aerospace and turbo-machinery industr...
