Standard Methods

with a pocket calculator have been removed. Details of calculations remain for readers to replicate, since otherwise statistical analysis becomes too ‘black box’. References are made to computer packages. Some of the analyses are now available on standard spreadsheet packages such as Microsoft Excel, and there are extensions to such packages for more sophisticated analyses. Also, there is now extensive free software on the Web for doing most of the calculations described here. For a list…

other more popular breeds in meat consumption. Intramuscular fat (IMF) content of pork muscle is considered to be a key factor that influences the sensory characteristics of both meat and meat products [5, 6]. To establish a fast and recognized standard quality of this autochthone meat, it became vital to study and create a physical-chemical characterization. The common techniques to determine meat quality parameters are extremely time consuming, destructive and expensive [7]. Roza de…

Renewable Energies CIEMAT Phone: +34-91-346 6422 - E-mail: felix.avia@ciemat.es Summary The new annex H of the standard IEC 61400-121 for Power Performance Testing of Small Wind Turbines (now in the approving process) was applied at CIEMAT test centre, on the characterization of the BORNAY 1500 Inclin Neo wind turbine. Results and findings obtained are presented. Keywords: Wind standards, autonomous wind systems, power performance evaluation, electrical systems, small wind turbines…

Unified Modeling Language (UML) is a standardized general-purpose modeling language in the field of object-oriented software engineering. The standard is managed, and was created, by the Object Management Group. It was first added to the list of OMG adopted technologies in 1997, and has since become the industry standard for modeling software-intensive systems.[1] UML includes a set of graphic notation techniques to create visual models of object-oriented software-intensive systems. UML is

to a known standard. Calibration to a traceable standard can be used to determine an instrument's bias, precision, and accuracy. In many countries, national standards for weights and measures are maintained by a National Measurement Institute (NMI) which provides the highest level of standards for the calibration / measurement traceability infrastructure in that country. Examples of government agencies include the National Physical Laboratory, UK (NPL) the National Institute of…

structural response, considering random input parameters. Several methods for probabilistic structural analysis have been studied in the last years. Generally, the methods employed are the Monte Carlo simulation method and First Order Reliability Method – FORM and Second Order Reliability Method. The Monte Carlo method is the most simple and evident way to accomplish a probabilistic analysis, and for that reason is widely used. In this method, material properties, loads and other random…

quality. • Technology transfer. VI. THE APPROACH RE-ENGINERRING SOFTWARE There are three different methods to access the software reengineering. The approaches differ in quantity and rate of replacement of existing systems to the target system. Each approach has benefits and risks of its own. 1. Approach BIG BANG BIG BANG approach to replace the entire system at a time, as shown in Figure 6, this method is often used for projects that issue to be resolved immediately. Such as moving to a…

custos. Um fator inelástico e de baixa oferta é o tempo. Quando o foco de diminuição de custos se dirige à economia de tempo, somos obrigados a rever os estudos de Taylor e seus seguidores. Atualmente há muitas empresas no mundo que utilizam o MTM (Methods-Time Measurement), um sistema de tempos pré-determinados desenvolvido por Maynard, Schwab e Stergemerten em 1948, que tem por base os estudos e princípios de Taylor descritos na Administração Científica. A experiência dessas empresas é…

Validação de Métodos: Este trabalho sendo em Excel tende a ser “personalizado demais”. O software deve procurar seguir o guia da Eurachem como regra, mas fornecendo opções adequadas quando preciso, com base em literaturas bem aceitas, como o “Standard Methods” na parte de Microbiologia. - Item 5.4.6 – Incerteza de Medição: O software deve procurar atender ao guia da Eurachem combinando todas as principais fontes de incertezas, mas procurando ter uma interface que facilite esta complexa…
