Man’s history and development endeavours have beenadvancing alongside a trail of ecological ramifications and climate change. Since prehistoric times, scientists have not recorded an accelerated shift in the ecologyof the planet during any other epoch beside that of modern man. The paper seeks to explore how man’s history and developmentaffects ecologyand climate. It uses desk analysis to recollect data from global assessment reportsand runs a One paired Sample Means t-Test, 1 tailed, 8 df, at Pearson Correlation value 0.458 and 0.5 alpha level. Findings show that, there is globalclimate change, seen in global warming trends; andimbalance in ecological footprint, seen in depletion of air, water and land sinks. The t-Test reveals significant net loss of global forest cover.The study also,apparently found that, processes ofdevelopment generally tend to damage ecology. Therefore,the study recommends a refocus to sustainable means of development.

Fuel cells are called the fourth electricity power generation after water, nuclear power generation devices. Fuel cells are widely recognized as very attractive devices to obtain directly electric energy from the electrochemical combustion of chemical products. When fuel cells are continuously supplied fuel and oxidant, electricity can be made constantly. According to the different electrolytes, fuel cells can be divided into different types among them, alkaline fuel cell is best as compared to others ones. Due to the activation overvoltage at the cathode is generally less than that with an acid electrolyte and there are very few standard chemicals that are cheaper than potassium hydroxide. These fuel cells have longer lifetimes, and do not require expensive noble metal catalysts to be used. Noble metal catalysts may be used, but less is needed to achieve a similar reaction rate. The main objective of the study is to use different kind of alcohols in alkaline fuel cell and determined the characteristics at different parameter.

Adequate and consistent energy supply is often regarded as a major factor in the development of any country. To add to this, the depletion of fossil fuels has also emphasised the need for alternate renewable energy solutions to meet global energy needs without inflicting any serious environmental impacts. Solar energy is globally acknowledged for its vast potential, as a source of providing most of the heating, cooling and electricity needs of the world. One of the most effective uses of solar energy is water heating. The use of solar energy to heat water has been proven to be a very economical, efficient and environmental friendly option for domestic as well as commercial applications. This study compares the feasibility of domestic solar water heater installation in three major cities of Pakistan i.e. Lahore, Karachi and Peshawar. The results show the solar water heater installation is most feasible in Peshawar, among the three selected cities.

In this paper the natural convection heat transfer from a horizontal plate embedded in a porous medium saturated with a nanofluid is numerically analyzed. By a similarity approach the partial differential equations are reduced to a set of two ordinary differential equations. In order to evaluate the influence of nanoparticles on the heat transfer, Ag and Cuo as the nanoparticles were selected. Results show that heat transfer rate (Nur) is a decreasing function of volume fraction of nanoparticles.

Since large power transformers belong to the most valuable assets in electrical power networks it is suitable to pay higher attention to these operating resources. Thermal impact leads not only to long-term oil/paper-insulation degradation; it is also a limiting factor for the transformer operation. Therefore, the knowledge of the temperature, especially the hottest spot (HST) temperature, is of high interest. This paper presents steady state temperature distribution of a power transformer layer-type winding using conjugated heat transfer analysis, therefore energy and Navier-Stokes equations are solved using finite difference method. Meanwhile, the effects of load conditions and type of oil on HST are investigated using the model. Oil in the transformer is assumed nearly incompressible and oil parameters such as thermal conductivity, special heat, viscosity, and density vary with temperature. Comparing the results with those obtained from finite integral transform checks the validity and accuracy of the proposed method

The dye-sensitized solar cells (DSSC) have gained the last decades an important place among photovoltaic technologies due to their low-cost of implementation and their performance, which becomes more efficient. The experimental data for this type of cells are enriched and accumulated quickly, given the enthusiasm for this new technology. The present work treats the equivalent circuit of a dye-sensitized solar cell (DSSC) for a model in an exponential, and by using the results of some works, we shall make a simulation by the software Scilab to obtain the characteristics (I-V), then we will study the influence of every parameter on the curve.

Employing Resistive Superconducting Fault Current Limiters (RSFCL) is one of the practical and effective methods to improve the transient stability of a power system by limiting the fault current. Regarding technical and economical constraints, optimal sizing and allocation of RSFCLs in a power system is of significant importance. It is the purpose of this paper to propose an algorithm based on the Particle Swarm Optimization (PSO) in order to improve the transient stability of a power system by optimal sizing and allocation of RSFCLs. The proposed algorithm is next applied to the New England 39-bus test system as a case study and the results are simulated in Matlab. Simulation results reveal that in the case of employing RSFCLs with sizes and locations resulted from the optimization algorithm, the transient stability of the power system under study is improved. Furthermore, it seems that the optimal locations of RSFCLs are to some extent near the fault location.

In Databases one of the active research fields is mapping relational databases (RDB) into Resource Description Framework (RDF). An enormous data is kept in the form of relational databases and accessing of data is done in the semantic web. The data stored in RDB is to be efficiently mapped to the semantic web or RDF for data availability to the users. There is a definite need for improvement in technologies for efficient mapping languages from RDB to RDF in semantic web. This paper presents an up-to-date survey of different RDB to RDF mapping languages proposed in recent times. It outlines the main features or characteristics to be considered for efficient mapping in different scenarios. The main objective of this content, pictures identification of limitations existing in the mapping languages. It also enhances the comparisons between each language and helps researchers to propose further better proposals in their future scope of work to improve better mapping techniques.

A way of exploiting the solar energy is to use cells photovoltaic which convert the energy conveyed by the incidental radiation in a continuous electric current. This conversation is based on the photovoltaic effect engendered by the absorption of photons. A part of the absorbed photons generates pairs electron-hole in which an electric field created in the zone of load of space of a junction p–n. Thus, the junction p-n, its characteristics, its components and its dimensions are the parameters responsible of the efficiency and the performances of a solar cell. To study this, we are going to use a very known software in the mode of the simulation of solar cells, the PC1D, and we are going, at the end, to draw a conclusion around the ideal parameters that a good solar cell has to have.

This paper contributes to design a Wind Emulator coupled to 1.5 kW Induction generator for Wind Energy Conversion System. A wind turbine emulator (WTE) is important equipment for developing wind energy conversion systems. It offers a controllable test environment that allows the evaluation and improvement of control schemes for electric generators that is hard to achieve with an actual wind turbine since the wind speed varies randomly. In this paper a wind emulator is modelled and simulated using MATLAB. Verification of the simulation results is done by experimental setup using DC motor-Induction generator set, LABVIEW and data acquisition card.

Mathematical heat transfer equations for finned double pipe heat exchangers based on experimental work carried out in the 1970s can be programmed in a spreadsheet for repetitive use. Thus avoiding CFD analysis which can be time consuming and costly. However, it is important that such mathematical equations be evaluated for their accuracy. This paper uses CFD methods in evaluating the accuracy of mathematical equations. Several models were created with varying; geometry, flue gas entry temperature, and flow rates. The analysis should provide designers and manufacturers a judgment on the expected level of accuracy when using mathematical modelling methodology. This paper simultaneously identifies best practices in carrying out such CFD analysis.

Energy dependent small developing island states are besieged to sustain potential rate of growth. This is due to increase in energy prices and lack of evidence based policy on long term sustainable energy use. This paper examines the long run relationship between economic growth, export and electricity consumption in Fiji over the period 1981-2011. Employing Granger causality test it is found that there is cointegrating relationship between economic growth, export and electricity consumption. The casual relationship between the variables was investigated within the error correction model framework. We found that in the long run causality runs from electricity consumption and export to economic growth. Based on this empirical analysis some important policy implications are suggested.

ZnO thin film were deposited by spray pyrolysis on glass substrates, using zinc nitrate as precursor with different molar concentrations varying from 0.05M to 0.2 M. To study the structural proprieties of the film , the different technique was used as the X-ray diffraction, atomic force microscopy (AFM), Raman scattering , and FTIR . The optical properties were explored by transmission, reflectivity and Photoluminescence techniques. The ZnO thin films obtained in this paper are polycrystallines, the grain size increases when the molar concentration of Zn precursor was increasing. The films are transparent in visible region, this transmission values decreases when the molar concentration increase caused by the increasing of surface roughness

A detailed investigation covering piped gas flow characteristics in high pressure flow conditions. Such flow analysis can be resolved using established mathematical equations known as the Fanno condition, which usually cover steady state, or final flow conditions. However, in real life, such flow conditions are transient, varying with time. This paper uses CFD analysis providing a split second “snapshot” at what happens at the pipe outlet, and therefore, a closer understanding at what happens at the pipe’s outlet in high pressure gas flow condition. In this example air was selected for simulation purposes. In HVAC applications, such gas flow conditions can occur in typical applications such as; air compressors releasing high pressure air through a pipe, or compressor over pressure refrigerant gas being released into the atmosphere via a discharge pipe. Investigation has shown that rather than a steady mass flow rate condition occurring at the pipe outlet, calculated by the Fanno flow condition, a spiked increase in flow rate occurs at the beginning,and then stabilizing after a few seconds, with relatively minor ripples in flow rate. Other observations were also made and commented. CFD results in mass flow rate were compared with the mathematically derived results, differences were recorded. The CFD analysis showed how the k-omega turbulence model performed well, with the processor stabilizing at an early stage.

Solving the unit commitment (UC) problem is one of the most complicated issues in power systems that its exact solving can be calculated by perfect counting of entire possible compounds of generative units. UC is equated as a nonlinear optimization with huge size. Purpose of solving this problem is to programming the optimization of the generative units to minimize the full action cost regarding problem constraints. In this article, a modified version of ant colony optimization (MACO) is introduced for solving the UC problem in a power system. ACO algorithm is a powerful optimization method which has the capability of fleeing from local minimums by performing flexible memory system. The efficiency of proposed method in two power system containing 4 and 10 generative units is indicated. Comparison of obtained results from the proposed method with results of the past well-known methods is a proof for suitability of performing the introduced algorithm in economic input and output of generative units.

A concept of a liquid tin anode-indirect carbon air fuel cell (LTA-ICFC) are described. Experimental setups for analysis of LTA-ICFC polarisations of an operational electrochemical reactor of the LTA-ICFC are presented. Results from Electrochemical Impedance Spectroscopy (EIS) Analysis of the electrochemical reactor of the LTA-ICFC are shown and analysed.The rate-determining step of the system is concluded. The charge-transfer resistance did not show considerable differences at 700-800 °C. This can be implied that the charge-transfer resistance is not the rate-limiting step of the transport processes of the fuel cell. The increase of the Warburg impedance concurrently with the resistance to fit mass-transport loss (R3) suggests that the rate-limiting step for the LTA-ICFC in voltage recovery mode is the diffusion of the oxide ions through SnO2 layer. The increment of mass transport lost, R3, of the cell causes the slowly increase of the cell’s voltage over the voltage from 0.7-0.8 V at 700, 750, and 800 °C.
