Abstract

Blocking probability has been one of the key performance indexes in the design of wavelength-routed all-optical WDM networks. Existing research has demonstrated that an effective Routing and Wavelength Assignment (RWA) algorithm and wavelength conversion are two primary vehicles for improving the blocking performance.. The Weighted least-congestion routing and first-fit wavelength assignment (WLCR-FF) algorithm considers both the current traffic load and the route lengths jointly. In this paper, Numerical study was conducted  over ring  and mesh-torus and NSFNET topology. A comparison was made between WLCR-FF and a wide variety of existing routing algorithms like static routing, fixed-alternate routing and least-loaded routing. The results conclusively demonstrate that the WLCR-FF algorithm can achieve much better blocking performance in the presence of sparse or/and full wavelength conversion.

Abstract

Composites structures are widely used both in military and commercial aircraft industries. Design of tapered composite skins is quite laborious and time consuming. Optimization of these composite skins is essential for realizing the full benefits offered by composites. Composite skins are optimized in two stages. In the first stage, thicknesses of various zones of composite skin along with the percentage of fiber orientations is computed using gradient based algorithms. In the second stage, the stacking sequence generation is performed mostly using knowledge based engineering approaches using rules and heuristics. The stacking sequence generation is a combinatorial problem and is quite complex. Such combinatorial problems can be solved elegantly by genetic algorithms. The available genetic algorithm based stacking sequence approaches are mostly theoretical and are demonstrated mainly as research and academic problem for laminates of constant thickness with few constraints. In this paper a genetic algorithm based approach for stacking sequence generation of tapered composite skins with multiple zones is presented. This approach is scalable and can solve large size composite skin generation problems with reasonably good number of constraints. The paper also demonstrates the usefulness of the current approach by solving few large scale stacking sequence generation problems in real life aircraft industry.

Abstract

Despite various developmental programmes announced by the Government time and again, incidence of poverty in the country still remains high. Self Help Groups (SHGs) represent a form of intervention that is a radical departure from most of the existing poverty alleviation programmes proved as an effective strategy of poverty alleviation, human development and social empowerment. The SHGs have been recognized as useful vehicles to help the poor in accessing financial resources, which were hitherto not available to them and has helped them break away from the clutches of exploitative moneylenders. Economic self-reliant people play a more active role in decision-making and are able to contribute to the economic growth. Access to financial services and the subsequent transfer of financial resources to poor people enable them become the economic agents of change. In this paper, an attempt has been made to analyze the impact of SHG in alleviation of poverty in India. The author also made an effort to show how SHGs become successful as a model of inclusive growth.It is observed that the percentage of BPL population is less in the states where there is large number of SHGs.

Abstract

Inclusive Growth model is accepted widely to incorporate social justice in development and in India, Inclusiveness, was a critical element in the strategy of IXth Five Year Plan. It was to achieve by ensuring broad-based growth and was combined with programmes aimed at overcoming deficiencies in critical areas, which affect large numbers of the vulnerable sections of the population. Financial inclusion is one of the area, where such programmes are planned and implemented. This paper attempts to provide discussions on the financial inclusion programmes in India basically with reference to finance to poor and women empowerment. Analysis of national agenda for reforms in the financial sector, key issues on financial inclusion, and evaluation of the financial inclusion programmes in India in terms of financing poor, financing women empowerment activities.
