Behaviour of the potentials due to strangeness degree of freedom in ΛΛ6_{\Lambda\Lambda}^6He hypernucleus

Fully correlated study of $_{\Lambda\Lambda} ^6$He hypernucleus has been performed with two- and three- baryon potentials. For the S=-2 sector, various simulations of Nijmegen $\Lambda\Lambda$ potential models have been used. We investigate the role of every strength of the strange sector potentials on the energy breakdown and present a crystal clear understanding of their interplay. Consistency between $_\Lambda ^5$He and $_{\Lambda\Lambda}^6$He depends on the $\Lambda N$ space-exchange strength only. Investigation limits the strength of simulated Nijmegen $\Lambda\Lambda$ potential models. The study is a step forward to determine all the strengths, to reslove A=5 anomaly and to search for $_{\Lambda\Lambda}^4$H in an authentic way.Comment: 4 pages, 1 figur

Quantization in Control Systems and Forward Error Analysis of Iterative Numerical Algorithms

The use of control theory to study iterative algorithms, which can be considered as dynamical systems, opens many opportunities to find new tools for analysis of algorithms. In this paper we show that results from the study of quantization effects in control systems can be used to find systematic ways for forward error analysis of iterative algorithms. The proposed schemes are applied to the classical iterative methods for solving a system of linear equations. The obtained bounds are compared with bounds given in the numerical analysis literature

BdbServer++: A User Driven Data Location and Retrieval Tool

The adoption of Grid technology has the potential to greatly aid the BaBar experiment. BdbServer was originally designed to extract copies of data from the Objectivity/DB database at SLAC and IN2P3. With data now stored in multiple locations in a variety of data formats, we are enhancing this tool. This will enable users to extract selected deep copies of event collections and ship them to the requested site using the facilities offered by the existing Grid infrastructure. By building on the work done by various groups in BaBar, and the European DataGrid, we have successfully expanded the capabilities of the BdbServer software. This should provide a framework for future work in data distribution.Comment: Paper based on the poster from the 2003 Computing in High Energy and Nuclear Physics (CHEP03), La Jolla, Ca, USA, March 2003, 4 pages, LaTeX, 0 figures.

Potential Contribution of Sharia Micro Financing on Poverty Reduction in Slum Communities in Makassar

Poverty is a problem faced by many countries. A country that has a high number of poor people, will always face various cases as a result of poverty, namely low education, high unemployment, health problems, criminal cases and prone to security problems. That is because the poor people not only lack money, but also do not have access to health services, food and education, so they are vulnerable to illness, malnutrition, and unable to get a good education. Considering its impact on people\u27s lives, it is deemed necessary to take actions that can reduce poverty. Governments in many countries and International institutions have also sought to help the poor throughout the world, through microfinance programs. This effort has succeeded in reducing poverty at the global level. On the other hand, poverty is still quite high. The dependence of the poor on poverty alleviation programs from the government often leads to community dependence on the government. They are just waiting for help to stay alive, so they cannot get out of the cycle of poverty. Therefore, in efforts to alleviate poverty, the important thing to do by the government and institutions involved in poverty reduction is to encourage the independence of the poor so that they can get out of the poverty circle by their own efforts. One effort to encourage the independence of the poor is to provide capital so that they can build their own business activities. In some circumstances, microfinance can be a strategy to provide a way out for the poor to escape poverty. This study aims to identify the potential contribution of Islamic microfinance to reduce poverty in slums in Makassar. The method used in this study is qualitative, in which data are collected through in-depth interviews with slum communities who have not been touched by access to financial institutions. Other interviews were conducted with the management of Islamic microfinance institutions. Interviews found that urban communities living in slums wanted to access financial institutions, but did not have the opportunity. While from the LKMS, it was stated that there are many financing programs provided for the poor. This shows that the opportunity to reduce poverty is very good with the large potential contribution of LKMS in encouraging the independence of the poor through business activities
