The aim of this study is to present a new method to predict project time and cost under uncertainty. Assuming that what happens in projects implementation which is expressed in the form of Earned Value Management (EVM) indicators is primarily related to the nature of randomness or unreliability, in this study, by using Monte Carlo simulation, and assuming a specific distribution for the time an...

Dieser Beitrag fokussiert die Frage, wie ein besseres Verständnis für Kommunikationsprozesse und Medienwahl in Innovationswettbewerben erlangt werden kann. Die Virtualisierung von Innovationswettbewerben ermöglicht den Einsatz vielfältiger Medien und verspricht Unternehmen Vorteile gegenüber der traditionellen physischen Integration. Aktuelle theoretische Konzepte erfassen die Art der Kommunika...

In this paper, performance of long term evolution (LTE) over fiber system is investigated by optical frequency multiplication (OFM) method to generate high-order millimeterwave (mm-wave) using a dual-electrode Mach-Zehnder modulator (DE-MZM) in radio over fiber. Here, optical double sideband subcarrier (DSBSC) scheme is adopted to overcome fiber dispersion-induced RF power fading. Experimental ...

Earned Schedule (ES) forecasting of project duration has been researched over several years. Overwhelmingly, in comparison to other EVM-based methods, ES has been affirmed to be better. However, the testing results from a study, which employed simulation techniques, indicated there were conditions in which ES performed poorly. These results create skepticism as to the reliability of ES forecast...

A low-cost rapid-prototyping system using Texas Instruments' (TI) TMS320C30 Evaluation Module (EVM) based on the MathWorks' development software is presented in this paper. The rapid prototyping system serves as an educational tool in learning digital signal processing (DSP) and seeing the concept realized in real time. The development software modules, Simulink, uses graphical block diagrams t...

The Java Virtual Machine Language (JVML) is rapidly emerging as the de-facto standard for representing portable code and Java Virtual Machines (JVMs) are increasingly being used as standard platforms for running applications. But how suitable are the JVMs and the associated JVML for this purpose? This paper argues that JVML has a serious drawback in that it is not extensible enough. This lack o...

This paper presents the estimation of bit error ratio (BER) from error vector magnitude (EVM) for M-ary quadrature amplitude modulation (QAM) formats in optical coherent systems employing carrier phase recovery with differential decoding to compensate for laser phase noise. Simulation results show that the relationship to estimate BER from EVM analysis for data-aided reception can also be appli...

To gratify the requirements of modern wireless communication, linearization of power amplifier (PA) becomes a foremost research field. Several linearization techniques have been introduced time to time. Digital pre-distortion linearization technique is the best linearization technique from other linearization techniques. In this paper, modified memory polynomial function is used to model PA and...
