Due to the nature of this violation, reasonable effort should be made to remove all past references to this paper, and future references should be made to the following article: "Principles of Top-Down Quantitative Analysis of Projects. Part 1: State Equation of Projects and Project Change Analysis" by Pavel Barseghyan, in PM World Today Vol XI, Issue V, May 2009, pp. 1-17 This paper presents the derivation of the state equation of projects that incorporates project size, project duration, project total effort, team size, team productivity and project difficulty. In contrast to existing bottom-up methods of project presentation in the form of statistical relationships between project parameters this new top-down methodology is not a data driven and therefore is more accurate and stable.

A new numerical method based on hybrid of Block-pulse and Rationalized Haar functions for numerical evaluation of integer and fractional order Fourier Bessel (Hankel) transform is proposed in this paper. Hybrid of Block-pulse and Rationalized Haar functions are used as a basis to expand a part of the integrand, rf(r), appearing in the Hankel transform integral. Thus transforming the integral into a Fourier-Bessel series and truncating it, an efficient, stable algorithm is obtained for the numerical evaluations of the Fourier Bessel (FB) transform of order v >-1. The proposed method is quite accurate and stable, as illustrated by given numerical examples with varying degree of random noise terms Εθi added to the data function f(r), where θi is a uniform random variable with values in [-1, 1].

High-quality software needs to meet both functional and non-functional requirements. In some cases, software must accomplish specific performance requirements, but most of the time, only high-level performance requirements are available: it is up to the developer to decide what performance should be expected from each part of the system. In this context, the MARTE profile was proposed by the OMG to extend UML for model-driven development of real-time and embedded systems, focusing on assisting early performance analysis and scheduling. We propose using the MARTE profile to derive the performance requirements of each action in an UML activity diagram from the requirements of the containing activity and some local annotations. In this work, we show how the MARTE profile can be used for this purpose, define algorithms for computing the required throughput and time limit for each action and study their theoretical and empirical performance. The algorithms have been integrated into the Papyrus UML diagram editor and feed back their results into the original model. Running both algorithms on activities with 225 paths requires 10 seconds on average.

Curvelet transform is a new extension of wavelet transform which aims to deal with interesting phenomena occurring along curves. Curvelet transform is particularly a challenging task to classify human organs in CT scans using gray-level information. An efficient implementation of curvelet transform for medical image segmentation and denoising has been presented in this paper. A comparison study has been carried out in this paper between different transforms which reveals that curvelet transform exhibits optimal representation of the region of interest (ROI) with better accuracy and less noise.
