Cost and schedule measures are the most important support activities for the success of a project; it provides the basis for process improvement and project management. This paper reports practical experiences on using EVM (Earned Value Management) and SPC(Statistical Process Control) in cost/ schedule measure. The analysis of experience data indicates the distributions of CPI(Cost Performance ...

© 2009 Sang-Woong Yoon et al. 601 ABSTRACT⎯This letter presents a high performance 2.4 GHz two-stage power amplifier (PA) operating in the temperature range from -30C to +85C for IEEE 802.11g, wireless local area network application. It is implemented in InGaP/GaAs hetero-junction bipolar transistor technology and has a bias circuit employing a temperature compensation technique for error vecto...

XGIOTTO [5] is a domain specific language for the implementation of embedded software applications with hard temporal constraints. The language is an extension of the original GIOTTO language [6]. In this report we present the XGIOTTO tool chain, composed of the compiler and a specialized virtual machine, Embedded Virtual Machine (EVM). The compiler checks for determinism (absence of races) and...

The objective behind this work is to describe the Extreme Vertices Model in the n-Dimensional Space (nD-EVM) and the way it represents nD Orthogonal Pseudo Polytopes (nD-OPPs) by considering only a subset of their vertices: the Extreme Vertices. There are presented the Regularized Boolean Operators and the way they assure the dimensional homogeneity. Algorithms for performing Regularized Boolea...

Diels-Alder chemistry has been used for the thermoreversible cross-linking of furan-functionalized ethylene/propylene (EPM) and ethylene/vinyl acetate (EVM) rubbers. Both furan-functionalized elastomers were successfully cross-linked with bismaleimide to yield products with a similar cross-link density. NMR relaxometry and SAXS measurements both show that the apolar EPM-g-furan precursor contai...

The error-in-variables-model (EVM) is the most statistically correct non-linear parameter estimation technique for reactivity ratio estimation. However, many polymer researchers are unaware of the advantages of EVM and therefore still choose to use rather erroneous or approximate methods. The procedure is straightforward but it is often avoided because it is seen as mathematically and computati...

Earned Value Management (EVM) is a methodology combining scope, schedule, and resource measurements to assess project performance progress. It involves integrating the three critical elements of covering work cost. Various benefits are associated with use EVM in management. This research aims analyze four units building construction projects using method consisting an analysis performance, esti...

Spectral precoding is a promising technique to suppress out-of-band emissions and comply with leakage constraints over adjacent frequency channels mask requirements on the unwanted emissions. However, spectral may distort original data vector, which formally expressed as error vector magnitude (EVM) between precoded vectors. Notably, EVM has deleterious impact performance of multiple-input mult...

OBJECTIVES Expectancy-Value Model (EVM) is the most structured model in psychology to predict attitudes by measuring attitudinal attributes (AAs) and relevant external variables. Because health value could be categorized as attitude, we aimed to apply EVM to explore its usefulness in explaining variances in health values and investigate underlying factors. METHODS Focus group discussion was c...

In a previous work, Orthogonal Polyhedra (OP) were proposed as geometric bounds in CSG. Primitives in the CSG model were approximated by their respective bounding boxes. The polyhedrical bound for the CSG object was obtained by applying the corresponding Boolean Algebra to those boxes. Also in that paper, a specific and very concise model for representing and handling OP was presented: the Extr...
