Abstract :

In a photovoltaic system, its power output is heavily reliant to the irradiance instantaneously and this make the efficiency of DC/DC converter using in the photovoltaic system reduces, especially during low irradiance period. This paper proposes a new DC/DC converter to improve the efficiency of a PV system. The main idea of the new DC/DC converter is developed a DC/DC converter with variable capacity to meet the variation in the output power of the photovoltaic system. The designed converter is combined from multi-small DC/DC converters to obtain a high enough capacity and these small DC/DC converters are able to switch on/off to change the percentage of power flowing through such as the power loss in small DC/DC converter is reduced.  This designed converter is verified via experiment shoots. The results indicate that the efficiency of proposed converter is higher than that with a conventional DC/DC converter.

Abstract :

The problem of alienation has been a persistent issue of man since the beginning of civilization and it has been discussed in the history of philosophy since beginning. But as a serious issue the problem of alienation come in to existence after the development of industrialization and technology in a mass scale. Some twentieth century thinkers, philosophers, psychologist, sociologist, and religious scholars prescribed the way to come out from alienation. But in contemporary philosophy the existentialists took the issue of alienation most seriously. They gave their own approach on this issue and propagate a humanistic point of view as a way to come out from alienation. They try to make the philosophy free from the clutches of objectivity and bring the man in center again. Other contemporary western philosophers also influenced by existential movement. For them also the problem of alienation is a serious issue especially the famous philosopher and psychologist Erich Fromm. Fromm observes that in twentieth century man finds himself in a highly mechanical culture dominated by technology. Because of over use and emphasis on technology man becomes alienated from his own personal being. Both existentialists and Erick Fromm believes that man’s subjectivity is lost in the highly technical and mechanical contemporary world. The main issue for these thinkers is not only to understand the concept of alienation but to find out the ways to eliminate the alienation. Through which a human can understand his true being and meaning of life. This is a descriptive paper. The objective of the paper is to explore the issue of alienation in contemporary world and to suggest the ways to come out from the alienation with special reference to Existentialism and Erick Fromm.

Abstract :

In the treatment of water to fight against corrosion, there are several techniques that can slow down this phenomenon and thus extend the service life of the pipes. Among these techniques, the use of corrosion inhibitors is one of them. It is in this context that the evolution of the aggressive and turbulent nature of the water of the Lubumbashi River has been studied experimentally through the determination of indicators such as pH, chemical potential, total alkalimetric titre, calcium hardness THCa, free chlorine content, dissolved oxygen content, SO42- sulfate ion content and Ryznard and Langelier index. Numerous relationships between the dose of the inhibitor and the physicochemical parameters of water have been established. Similarly, it has also been shown that the dose variation of the inhibitor is related to the Langelier index and the Ryznard index. Thus it follows that with the dose of 0.30ml / L, an appreciable decrease in dissolved oxygen, which is the main oxidant in basic medium, is recorded. The use of the inhibitor has a positive effect on corrosion because it acts directly on all physicochemical parameters and on all oxidants. Subject to economic analyzes, the dose of 0.30 ml / L is more advisable especially as it would prevent in the cooling circuit degradation of the thermal coefficient and the formation of precipitates in the exchangers occasioned.

Abstract :

This paper proposes an incorporated algorithm for solving the power economic dispatch problem (PEDP) of generating units with fuel changes. The particle swarm optimization (PSO) enhances the proposed method efficaciously find and accurately search. The multiple updating (MU) can help the incorporated algorithm prevent deforming the augmented Lagrange function and caused difficultly in searching an optimal solution. The incorporated approach (PSO-MU) combines the PSO and a MU that has benefits of adopting a widespread area of punishment parameters and a small-size population. The proposed PSO-MU has been demonstrated on a practical ten power generators system; each generating unit is composed of two or three fuel sources. The entire generating cost of PEDP got by the proposed algorithm has been competed with previous researches for validating its efficacy. Simulation results of three examples clearly show that the incorporated algorithm is an effective alternative for solving PEDP of generating units with fuel changes in the realistic operation of power system.

Abstract :

Distributed power generation (DG) projects have the advantages of being close to load centers and easy to consumption. These characteristics, together with the incentive of subsidy policy, have led to the rapid development of DG projects in China. However, subsidies put a lot of fiscal pressure to the government. We need to explore other models that can encourage DG investment. Based on the supply chain coordination theory, both centralized and decentralized decision-making modes are discussed in the paper. The capacity investment and coordination models of profit distribution and risk allocation between the DG owners and investors are designed under the constraint of market demand. The research shows that the risk sharing model and the modified profit sharing model can achieve the optimal DG capacity in the centralized decision-making mode. Both of them can realize the coordination of the supply chain. The design and implementation of these mechanisms can promote the scientific and sustainable development of China's DG to some extent.
