Electromigration (EM) is re-emerging as a significant problem in modern integrated circuits (IC). Especially in power grids, due to shrinking wire widths and increasing current densities, there is little or no margin left between the predicted EM stress and that allowed by the EM design rules. Statistical Electromigration Budgeting (SEB) estimates the reliability of the grid by considering it entirely as a series system. However, a power grid with its many parallel paths has much inherent redundancy. In this work, we propose a new model to estimate the MTF and reliability of the power grid under the influence of EM, which accounts for these redundancies. We refer to this as the mesh model.To implement the mesh model, we also develop a framework to estimate the change in statistics of an interconnect as its effective-EM current varies. The proposed algorithm is quite fast and has an overall observed empirical complexity of O(n 1.5−1.6 ). The resultsindicate that the series model, which is currently used in the industry, gives a pessimistic estimate of power grid MTF and reliability by a factor of 3-4.ii

In Lebanon, the majority of organizations work as Small and Medium Enterprises (SMEs). SMEs play an important role in the monetary improvement of numerous countries. This paper utilizes current viewpoints to analyze the variables influencing venture, efficiency and development of SMEs in Lebanon. It explores main factors affecting investment and productivity as follows: flexibility,customers and employee’s relations, motivation of the owners, education of the labour force, access to infrastructure, access to finance, size of firms and other business climate variables. Other business climate variables are insecurity, bribe or corruption, the amount of time that businesses spend dealing with government regulation, poor power availability, etc. The most concerning issue for small and medium sized enterprises (SMEs) is not the idea or the product provided and neither its customers, but their needs. High costs of operations and office space are basics to the survival of a private venture. Incubators come as a reaction to the necessities of SMEs in key strides of a business, for example, commencement and market entrance. An incubator aims to have a positive effect on the economic health of an area, of a community even on a country.
