    Reliable population of the condition databases is critical for the correct operation of the online selection as well as of the offline reconstruction and analysis of data. We will describe here the system put in place in the CMS experiment to populate the database and make condition data promptly available both online for the high-level trigger and offline for reconstruction. The system, designed for high flexibility to cope with very different data sources, uses POOL-ORA technology in order to store data in an object format that best matches the object oriented paradigm for \texttt{C++} programming language used in the CMS offline software. In order to ensure consistency among the various subdetectors, a dedicated package, PopCon (Populator of Condition Objects), is used to store data online. The data are then automatically streamed to the offline database hence immediately accessible offline worldwide. This mechanism was intensively used during 2008 in the test-runs with cosmic rays. The experience of this first months of operation will be discussed in detail.Comment: 15 pages, submitter to JOP, CHEP0

    DEAR COLLEAGUES It is my pleasure and honour to welcome you to the website of the Egyptian Fertility and Sterility Society (EFSS). The EFSS has been established for more than twenty five years. The society is dedicated to the promotion of women’s reproductive health. The EFSS has been, for the past two decades, committed to the education, training and research in various disciplines of reproductive health. The society activity varied between holding Annual International Conference, running workshops and organizing national regional meetings. The society also releases its journal twice yearly which hosts review articles written by invited international figures in their fields as well as peer reviewed research articles. You may enjoy the content of the EFSS journal by navigating through this site. Announcements of the society activities as well as scenes of these events and many of the EFSS meetings power point presentations can be accessed through this website. I wish that visiting the EFSS website becomes an unstoppable habit supplying you with valuable information. Yours sincerely Prof. Amr El-Shalakany Secretary General of the Societ

    Recent Research Results on the Conditional Distribution Approach for Data Perturbation

    In this extended abstract, we provide a summary of our recent research on developing a theoretical basis for perturbation methods. We propose that, theoretically, generating perturbed values of the confidential variables from the conditional distribution of the confidential variables given the non-confidential variables, but independent of the original confidential variables. We show that if the perturbed values are generated from this approach, the resulting perturbed values have the same statistical characteristics as the original confidential variables, and maintain all relationships among the variables to be the same after perturbation as before perturbation. Furthermore, since given the nonconfidential variables, the perturbed variables are independent of the original confidential variables, this method also provides intruders with no knowledge gain. For a complete description, please see Muralidhar and Sarathy (2003). In the following sections, we describe our efforts in developing techniques based on this theoretical approach for numerical, confidential variables. Our initial effort focused on the desire to improve the performance of existing additive noise techniques for numerical, confidential variables. One of the key aspects of nois

    Variability@ER’11 - Workshop on Software Variability

    As software requirements constantly increase in size and complexity, the need for methods, formalisms, techniques, tools and languages for managing and evolving software artifacts become crucial. One way to manage variability when dealing with a rapidly growing variety of software products is through developing and maintaining families of software products rather than individual products. Variability management is concerned with controlling the versions and the possible variants of software systems. Variability management gained a special interest in various software-related areas in different phases of the software development lifecycle. These areas include conceptual modeling, product line engineering, feature analysis, software reuse, configuration management, generative programming and programming language design. In the context of conceptual modeling, the terminology of variability management has been investigated, yielding ontologies, modeling languages, and classification frameworks. In the areas of software product line engineering and feature analysis, methods for developing core assets and efficiently using them in particular contexts have been introduced. In the software reuse and configuration management fields, different mechanisms for reusing software artifacts and managing software versions have been proposed, including adoption, specialization, controlled extension, parameterization, configuration, generation, template instantiation, analogy construction, assembly, and so on. Finally, generative programming deals with developing programs that synthesize or generate other programs and programming language design provides techniques for expressing and exploiting commonality of source code artifacts, but also for specifying the allowed or potential variability, whether it is static or dynamic. The purpose of this workshop is to promote the theme of variability management from all or part of these different perspectives, identifying possible points of synergy, common problems and solutions, and visions for the future of the area
