Nickel–rubber nanocomposites were synthesized by incorporating ferromagnetic nickel nanoparticles in a natural rubber as well as neoprene rubber matrix. Complex dielectric permittivity and magnetic permeability of these composites were evaluated in the X-band microwave frequencies at room temperature using cavity perturbation technique. The dielectric loss in natural rubber is smaller compared to neoprene rubber. A steady increase in the dielectric permittivity is observed with increase in the content of nickel in both the composites. The magnetic permeability exhibits a steady decrease with increase in frequency and magnetic loss shows a relaxation at 8 GHz. The suitability of these composites as microwave absorbers is modeled based on the reflection loss which is dependant on the real and imaginary components of the complex dielectric permittivity and magnetic permeability.

IT and related services played a major role for India’s current 9.2. GDP growth. Organized retailing in India is one more example for its open economy. The IT industries where able develop a demand for Indian talents all over the world and improved their living standards. It directly impacts only a small minority of Indian population while organized retail affects every single Indian and every sector of Indian society. The paper gives a glimpse of the slow evolution of retail market over the years in India and its contribution for economic growth. The likely positive impact of this revolution in different sectors is enumerated. Paper addresses its ability to manipulate consumption pattern of society, increased customer satisfaction and likely change in the market shares of the different types of sellers. Paper discusses its flip sides like increasing social tension among families below poverty line and greater loss of self employment opportunities by this revolution. The main theme of enquiry of this paper is what it all means for the Indian society.

This paper presents Reinforcement Learning (RL) approaches to Economic Dispatch problem. In this paper, formulation of Economic Dispatch as a multi stage decision making problem is carried out, then two variants of RL algorithms are presented. A third algorithm which takes into consideration the transmission losses is also explained. Efficiency and flexibility of the proposed algorithms are demonstrated through different representative systems: a three generator system with given generation cost table, IEEE 30 bus system with quadratic cost functions, 10 generator system having piecewise quadratic cost functions and a 20 generator system considering transmission losses. A comparison of the computation times of different algorithms is also carried out.
