An objective of Earned Value Management (EVM) is to provide a means for predicting the outcome of a project. Inherently, the outcome is largely determined in the planning, and of course completion forecasting commonly occurs with analysis of project performance. Having the project plan, management would like to be able to quantify its risk What is the likelihood for having a successful project ...

این مقاله ضمن تحلیل و بسط دو مفهوم ارزش ذاتی و ارزش ابزاری در حوزه طبیعت و محیط زیست و تطبیق آن با رویکردها و نحله های غالب فلسفه و اخلاق محیط زیست به مطالعه این بحث در حوزه حقوقی، بویژه حوزه مربوط به خسارات زیست محیطی و ارزیابی آنها پرداخته است. فرض اساسی این نوشتار براین امر استوار است که هنوز قوانین و رویکردهای حوزه محیط زیست رنگ و بویی مبتنی بر انسان محوری دارند و از رویکردهای طبیعت محوری ک...

BACKGROUND The highest incidence of meningitis occurs during the neonatal period and (then) infancy. Although Bacterial agents are the most dangerous cause of neonatal and childhood meningitis yet viruses especially, enteroviruses (EV), are by far the most common cause of meningitis in this age group. OBJECTIVES The aim of the current study was to evaluate the role of EVs in neonatal and chil...

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 ...

RF power amplifiers in mobile WiMAX transceivers operate in an inherently nonlinear manner. It is possible to amplify the signal in the linear region, and avoid distortion, using output power back-off; however, this approach may suffer significant reduction in efficiency and power output. This paper investigates the use of Doherty techniques instead of back-off, to simultaneously achieve good e...

© 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...

—High peak-to-average ratio power (PAPR) is a critical practical problem for an OFDM system. Many techniques, such as clipping and filtering (ICF), cognitive clipping, have been proposed to deal with the issue. However, it needs to determine the relationship between error vector magnitude (EVM) and clipping ratio (CR). In this paper, we formulate a universal PAPR optimization model with EVM co...

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...
