Abstract

Fossil fuels is the main energy resource now a day with the advantage of generating gigantic electricity at a given location. Fossil resources, however, are subject to exhaustion rendering energy resources risks. The process of electricity generation from fossils fuels may be less costly compared to other schemes however this advantage comes at the expense of increased pollution, greenhouse gases emission contributing to overall global warming. Sustainable energy production requires reusable energy resources. Each renewable energy resource is characterized by a unique characteristic set and advantages, making it suitable for application of specific nature and location. In a hybrid system, the cummulative sum of the powers generated by the constituent systems should match the load demand rendering its implementation complex mainly due to the non linear behavior of the renewable energy resources and the non linearity of the fuel consumption curve. The dissimilar load demand pattern and the limit on the operation of the battery also poses a constraint. Controlling the process of any compound power source system in an optimal manner is essential and challenging to achieve low overall system cost.

Abstract

The aircraft complex systems (ACS) contains the auxiliary power unit (APU) based gas turbine, the performance assessment is totally cramped to inspection of different kind of parameters. So many other parameters can be observed in Quick Access Recorder (QAR) returns the APU condition from different aspects not having enough attention. The investigation intends to propose incorporated performance indicators by feature extraction many observing parameters. To approve the effectiveness of the strategy by anomaly identification, the clustering analysis is conducted. This technique can possibly effectively evaluate performance of some complex aircraft systems for early cautioning and prevent degradation at early stage. The parameters of Rowens model for APU based gas turbines in unique studies are assessed by utilization of accessible operational and performance data. Here, the work is planned to make understanding into different parts of the APU model and to present simple and comprehensive strategy to extract the parameters out of basic physical laws, focusing especially on researchers to let their interest in dynamic models and simulations. Gas turbine parameters are approximated by using straightforward thermodynamic assumptions, resulting great performance. In this paper, the step response of the simulation model is also simulated for number of scenarios and is presented here.

Formation Control of Unmanned Vehicles via Extended Feedback Consensus

Vol. 5, Issue 10, PP. 211-215, October 2018

Published online Formation Control of Unmanned Vehicles via Extended Feedback Consensus

PDF

Abstract

This paper has considered the problem of formation control of multiple quadrotor using a diversiﬁed feedback linearization technique. Taking the advantage of double integrator which normally can achieve any unrestrained shape, we have devised a linearization technique that is made possible using extended feedback. The technique has the ability of transmuting the dynamics of a quadrotor’s reference point to four double integrators in accordance with yaw angle and position of quadrotor in the space. The traditional exact feedback technique require a jerk (which is the derivative of acceleration) but it is not an issue for the extended feedback method. Ending by the conclusion the section numerical example elucidate formation control of quadrotor by using reference point and center of masses of the quadrotors.

Signal Path Loss Measurement for Future Terahertz Wireless Propagation Links

Vol. 5, Issue 10, PP. 193-197, October 2018

Published online Signal Path Loss Measurement for Future Terahertz Wireless Propagation Links

PDF

Abstract

Terahertz Band (100GHz-10THz) offers larger bandwidth and ultra-higher data rates and is visualized as a key technology to alleviate the capacity limitation and spectrum scarcity of the currents wireless networks. There are some competent development and design challenges in the realization of wireless terahertz network. Signal high path loss is one of the major constraints for enabling wireless communication networks in the terahertz band. Thus for the consummation of wireless propagation links in the THz band an equivalent signal path loss model is designed incorporating the major peculiarities of the wireless channel that accounts for terahertz wave propagation in LoS propagation. The equivalent path loss model for terahertz LoS propagation is developed and simulated in matlabR. The simulation results are compared with the lognormal path loss model results.

Abstract

Electrocatalytic activity at cathode in Polymer Exchange membrane fuel cell (PEMFC) is sluggish and requires a most active catalyst. Till now Platinium (Pt) is considered as the most feasible and active catalyst for Oxygen reduction reaction at cathode. It is most expensive and also faces the problem of poisioning due to carbon monoxide, hence a more reactive, durable catalyst is required to meet the demand for commercialization. In this study a novel non platinum group metal (N-PGM) Ni nanotubes were prepared by using hydrothermal technique using transition metal precursor with profound insight.Ni nano tubes were obtained after pyrolyzing Ni Zeolitic Imidazolate Framework (Ni/ZIF) at 800 0C under inert nitrogen atmosphere.It’s electro catalytic performance was examined by Linear Sweep Voltammetry (LSV) done with Rotating Disk Electrode (RDE) evaluation shows that, Ni nanotubes owns splendid electro catalytic behavior for Oxygen Reduction Reaction (ORR) in basic environment. It depicts a current density of -2.6mA/cm2 and an over potential of -0.28V Vs. Saturated Calomel Electrode (SCE), and RDE Results were obtained at 400,800,1200 and 1600 rpm in 0.1M KOH solution while the Ni/ZIF shows the minimum -1.4 mA/cm2..The Pt/C catalyst was also analyzed in the same environment for comparison purpose having a current density of -4.6 mA / cm2. The results reflect that Ni nanotubes is promising catalyst for Proton exchange membrane (PEM) fuel cell.

Abstract

Electrical energy is one of the most important component in the development of any society. Electrical energy is primarily generated from fossil fuels, nuclear power or hydro but an increasing gap between demand and generation is leading is to find an alternative energy sources that produce clean energy and meet our increasing needs while maintaining the secure and reliable operation of power system. Presently Pakistan is facing extreme energy crisis and the situation is even worse in remote areas that are deprived from basic facility of electrical energy. These areas are normally gifted from natural resources that can play a key role in overcoming this problem. Run on River hydro generating units, solar Photovoltaic cells and Biomass generating units are able to generate clean electrical energy and meet the local demands; however, it is important that the frequency and voltage of that area is maintained within in the specified for the secure operation of power system. The voltage control plays important role in stable and reliable power supply. This research project will model a standalone micro grid where electrical energy will be generated from alternative sources of energy that are renewable i.e. hydro, solar irradiations and biomass resources, and then will employ specific technique for voltage control. This study will analyze the system behavior in different seasons when the load demand varies.

Abstract

This paper presents the effect of fly ash as reinforcement on mechanical behavior of aluminum alloy. 5% by weight of untreated fly ash was used as a reinforcement to fabricate the composite samples by sand casting technique. Tensile, Hardness and Fatigue tests were carried out for the samples. It has been observed that by the addition of fly ash to aluminum alloy improves the ultimate tensile strength(UTS) and hardness by 15.87% and 5.64% repectively as compared to sand casted simple aluminum alloy.Similarly fatigue tests reveal that fly ash reinforced aluminum composite has greater fatigue life than the unreinforced aluminum alloy.

Abstract

Rural electrification requires to be designed in a sustainable way to improve the quality of life of rural communities. Pakistan is facing an acute energy crisis for years now. Pakistan’s energy mix mainly depends on indigenous natural gas and oil. Due to imports of oil and rapid decrease in gas reserves, there is a significant burden on the economy of Pakistan, which has forced the planners and policy makers to look for renewable energy sources. Micro Hydro Power (MHP) is an example of renewable energy which can be sustainable economically, environmentally and socially as Pakistan is rich in micro-hydro power especially the northern side. This paper analyses the outcomes from a field survey which is conducted in district Shangla, KPK Pakistan, where different agencies have implemented different MHP Projects (MHPPs). The quantitative and qualitative analyses have been used for comparing two MHPPs based on electricity tariff, community involvement, effect on the society and other factors. Quite a few issues were found due to lack of knowledge or unskilful operators in maintenance and operation in these MHPPs which are barriers to sustainable development. This research work concludes that these MHPPs requires proper management, quality work and skilful operators to have a sustainable and reliable system for the community. The MHPPs area already contributing significantly in the development of local communities.

An investigation on the Flow Behavior in the Airfoil of a Flapping Wing

Vol. 5, Issue 9, PP. 138-146, September 2018

Published online An investigation on the Flow Behavior in the Airfoil of a Flapping Wing

PDF

Abstract

In this investigation, the two-dimensional dynamic analyses of the wing airfoil of a swing-wing micro air vehicle (MAV) were carried under restrained pitching and flapping oscillations, which varied in the 10-degree oscillation range and the 0.1-10 reduced frequency range. The flow was in a laminar flow with a Reynolds number of 1100. The objective of this simulation was to study the flow behavior in the dynamic motions in a dynamic stall regime. Similar studies on the dynamic stall regime with low Reynolds numbers have not resulted in a particular numerical solution and have separately studied the parameters influencing the numerical solution. The most critical dynamic motions that require utmost precision in numerical analyses were reviewed and validated in this research. The results of the numerical research analyses were compared to the experimental results obtained with a water tunnel.

In-situ Combustion: Reservoir Candidacy/Project Selection Criteria(s) For Niger Delta Heavy Oil Reservoirs

Vol. 5, Issue 9, PP. 130-137, September 2018

Published online In-situ Combustion: Reservoir Candidacy/Project Selection Criteria(s) For Niger Delta Heavy Oil Reservoirs

PDF

Abstract

There is a drastic need for the oil companies operating within the onshore(s) and offshore(s) of Nigeria to critically start looking at the various possibilities of heavy oil production from the nation’s various fields located in the Niger Delta region using already available Enhanced Oil Recovery techniques/methods such as In-situ combustion (ISC), CHOPS and SAGD. This study focused on In-situ combustion as a means of enhancing likely heavy oil production in the Niger Delta using the Nelson & McNeil 1961 ISC model. The study developed applicable screening criteria(s) for both reservoir candidacy and ISC project selection in the Niger Delta. Corresponding programs and flow-charts that would allow petroleum engineers in the Niger Delta to theoretically evaluate production performances using his/her computer(s) was also developed. It was discovered also during our course of work that all six reservoirs considered in both Case 1 (Venezuela reservoir) and Case 2 (Niger Delta reservoirs) met this study’s reservoir candidacy selection criteria(s) for possible applicability of an ISC project performance evaluation(s) with respect to enhancing oil production. These reservoirs were further graded / ranked based on their theoretical ISC project performances as calculated and evaluated using a well known ISC model as documented in the ISC handbook.

Published online Existence Criteria and Hyers-Ulam Theorem for a Coupled P-Laplacian System of Fractional Differential Equations

PDF

Dealing with high order coupled systems of FDEs through nonlinear p-Laplacian operator. We analyze existence, uniqueness & Hyer-Ulam stability (HUS) of the solutions by means of topological degree method. For this purpose, we transform the supposed problem into an integral system via Green�s function(s) and assume certain operator equivalent to the integral form of the problem. Then after, the results are proved with some necessary assumptions.

Published online Geomechanical Principles of Hydraulic Fracturing Method in Unconventional Gas Reservoirs

ePub PDF

Abstract

Unconventional gas production from shale formation is not new to oil and gas experts worldwide. But our research work was built around hydraulic fracturing technique with focus on the Perkins Kern-Nordgren (PKN) 1972 hydraulic fracturing model(s). It is a very robust and flexible model that can be used on two major shale reservoirs (with the assumption of a fixed height and fracture fluid pressure). The essence was to compare detailed geo-mechanical parameters extracted from wire-line logs with Perkin-C model to select the right well as candidate for simulation. It aided in the prediction production of shale gas from tight shale formations. These also helped in reviewing safe and economical ways of obtaining clean energy sources. Based on similarities in well and formation properties our research team subjected IDJE-2 well (located in the Agbada shale Formation of Niger Delta, Nigeria) to various conditions, equations and assumptions proposed by the study model while also validating our results with the PENOBSCOT L-30 well, located in Canada (with existing profound results from stimulations). The PENOBSCOT L-30 well (Case 1) and IDJE-2 well (Case 2) were both subjected to same conditions, equations and assumptions as applicable to the study model to enable us compare and evaluate stimulation performances. But both cases tend to react differently. However the fluid behavior at constant injection time increases at about 99.64%. Whereas, the maximum width at wellbore shows that a constant increase of fracture width will yield an increase in propant permeability, tensile strength and Poissons ratio for Case 1 & 2. Our research results show how rock properties can affect fracture geometry and expected production rates from stimulated shale reservoir formations

Novel Approach to Develop an Efficient Boost Converter by Using Coupled Inductors

Vol. 5, Issue 4, PP. 61-67, April 2018

Published online Novel Approach to Develop an Efficient Boost Converter by Using Coupled Inductors

PDF

Abstract

This paper focuses on the new approach to develop an efficient Boost Converter by using coupled inductors. In order to eliminate voltage spikes, a buffer circuit is used in the converter. Coupling coils generate leakage flux, and energy in the leakage flux causes voltage spikes. With a high boost ratio, the active switches in the converter can maintain the proper duty cycle, which can significantly reduce voltage and current stress. Since the main switch and the auxiliary switch can be turned on by the zero voltage switching, the switching loss is reduced, and the conversion efficiency is significantly improved. In this paper, an experiment was conducted by building a 200W boost converter model. The results show that the conversion efficiency is greater than 90%, and the surge phenomenon can be effectively suppressed. Finally, the feasibility of low-voltage input systems was verified by photovoltaic and battery system.

Abstract

There are millions of texts store in both off line and online forms. To utilize these documents properly, there is need of organizing these documents systematically and lots of applications are available for this purpose. Text classification is an important area of image processing deal with how the document belongs to its suitable class or category. Like other languages, Arabic language is also very rich and complex inflectional language which makes Arabic language very complex for ordinary analysis. In this review paper, we focus on the published research, especially in the field of Arabic text classification. Regard these all, three different types of feature extraction techniques are also implemented to extract features from different images of Arabic characters and presents a performance results of these techniques. From the result, it can be concluded that the combination of Linear binary pattern descriptor and Legendre moment, based moments features outperform and increase the accuracy of the LBP classifiers from 91.99 % to 93.12%.

Published online Optimizing Computations in Intermittently Powered Wireless Sensor Nodes

PDF

Abstract

Communicating man and machine is always beneficial when their linkage is for information exchange. Information Communication Technologies (ICT) thus seek for such technologies and communication schemes where it can eliminate the use of frequent, time to time re-programming as well as charging/ topping up the battery resource. For the same purpose, researchers are always into the development of such Wireless networking based schemes where the battery constrains are minimized. Internet of things (IoT) is one of these emerging technologies. This research focuses on the implementation of IoT based techniques to minimize the battery re-charge time by studying the behavior of motes (Nodes in IoT) with respect to its information exchange, network throughput and power management. The research uses capacitor driven motes that can accept data wirelessly and transmit it directly after its reception or can restart the mote while the data is being preserved in its Read only flash. There different scenarios have been sequentially analyzed for incremental number of nodes from 2 to 15, whereas the capacitance is calculated for nominal data transfer. The results conclude that once the deployment of the network goes from scares to densely populated network, the charge due to the modeâ™s capacitance exponentially optimizes. The research concludes that lower number of nodes must be greater in order to use higher capacitance values whereas lower network density must follow the strategy of broadcasting its data without writing it on Read only flash memory.

Design of Optimal Linear Quadratic Gaussian (LQG) Controller for Load Frequency Control (LFC) using Genetic Algorithm (G.A) in Power System

Vol. 5, Issue 3, PP. 40-49, March 2018

Published online Design of Optimal Linear Quadratic Gaussian (LQG) Controller for Load Frequency Control (LFC) using Genetic Algorithm (G.A) in Power System

PDF

Abstract

Nowadays power demand is increasing continuously and the biggest challenge for the power system is to provide good quality of power to the consumer under changing load conditions. When real power changes, system frequency gets affected while reactive power is dependent on variation in voltage value. For satisfactory operation the frequency of power system should be kept near constant value. Many techniques have been proposed to obtain constant value of frequency and to overcome any deviations. The Load Frequency Control (LFC) is used to restore the balance between load and generation by means of speed control. The main goal of LFC is to minimize the frequency deviations to zero. LFC incorporates an appropriate control system which is having the capability to bring the frequency of the Power system back to original set point values or very near to set point values effectively after the load change. This can be achieved by using a conventional controller like PID but the conventional controller is very slow in operation. Modern and optimal controllers are much faster and they also give better output response than conventional controllers. Linear Quadratic Regulator (LQR) is an advanced control technique in feedback control systems. It’s a control strategy based on minimizing a quadratic performance index. In despite of good results obtained from this method, the control design is not a straight forward task due to the trial and error involved in the selection of weight matrices Q and R. In this case, it may be hard to tune the controller parameters to obtain the optimal behaviour of the system. The difficulty to determine the weight matrices Q and R in LQR controller is solved using Genetic Algorithm (G.A). In this research Paper, G.A based LQG controller which is the combination of LQR and Kalman Filter is feedback in LFC using MATLAB/SIMULINK software package. Reduction in frequency deviations and settling time was successfully achieved by using LQG Controller with LFC based on G.A.

Published online Effect of Sandstone on Concrete Procedure With Plastic Synthetic Aggregate

PDF

Abstract

In this research work, the effect of sandstone (SS) on concrete produced with plastic synthetic aggregate (PSA) was investigated. A mix proportion of 1:1.6:3.6 with water cement ratio of 0.50 were used. The percentage replacement of coarse aggregate (CA) with plastic synthetic aggregate and plastic synthetic aggregate/sandstone used were 0%, 5%, 10%, 20%, 30% and 40%. Concrete cubes of 150mmxl50mmxl50mm of CA/PSA and CA/PSA/SS were cast and cured at 3.7,28,60 and 90 days respectively. At the ends of each hydration period, the concrete cubes were crushed and their .compressive strength was determined. The result of compressive strength of 5-40% replacement of coarse aggregate with plastic synthetic aggregate ranges from 8.07-36.7lN/mm2 as against 24.55- 41.21N/mm2 for the control test. The result of the compressive strength of 5-40% replacement of coarse aggregate with plastic synthetic aggregate and sandstone ranges from 5.05-31.75N/mm2 as against 24.58- 41.21N/mm2 for the control test. The workability for 5-40% replacement of coarse aggregate with plastic synthetic aggregate ranges from 15-68mm as against 8mm for the control test (0% replacement).

A Novel Method for Insulation Testing of High Voltage Electrical Equipment

Vol. 5, Issue 2, PP. 32-36, February 2018

Published online A Novel Method for Insulation Testing of High Voltage Electrical Equipment

PDF

Abstract

Different equipment’s are used to test the insulation of electrical machines and measure the break down voltages of different materials, e.g. Rogowski Profile, Borda Profile and fluke insulation tester. These testing techniques works on a common principle of applying a very high voltage across the insulating material and keep increasing the voltage which increases the electric field until the breakdown voltage is reached where the insulation breaks down. Different materials are tested via insulation testers to determine their breakdown voltages so that the corresponding correct materials are used accordingly in different situations. Devices with higher impurities causes sparks and arcing, so dielectrics having higher breakdowns should be used as their insulation, otherwise, a suitable dielectric should be used. This paper offers a novel method to overcome the above-mentioned problems using an insulation testing device that should be automated, less bulky, less expensive, portable and which shall be easy to use with higher degree of safety.

Grid Integration of Multistring Photovoltaic Plants with Modular Multilevel Converter

Vol. 5, Issue 2, PP. 16-20, February 2018

Published online Grid Integration of Multistring Photovoltaic Plants with Modular Multilevel Converter

PDF

Abstract

This paper presents the application of Modular Multilevel Converter (MMC) for connecting multistring photovoltaic generation plant. The proposed approach makes it possible for an increased PV plant capacity to be integrated with the grid, while also improving efficiency of conversion and power quality. To increase the efficiency of individual PV module, a DC-DC boost converter is employed with maximum power point tracking (MPPT). The MPPT is implemented by employing Perturb & Observe (P&O) algorithm. The PV modules with DC-DC boost converters are connected in parallel to form a DC bus which is connected to the utility grid with MMC. The MMC inverts the DC bus voltage for interfacing to the grid while maintaining the DC bus voltage constant. The simulation of the overall system in Simulink/MATLAB verifies the validity of the proposed system.

Static VAR Compensator for Weak Grid Systems

Vol. 5, Issue 1, PP. 10-15, January 2018

Published online Static VAR Compensator for Weak Grid Systems

PDF

Abstract

In our daily routine life majority of electric loads usedare inductive in nature. Adequate supply of active power and reactive power must be supplied to these loads to ensure proper operation. If not provided with required active power and reactive power, these inductive loads burdens the system unnecessarily. Hence resulting in low power factor.In a local electrical distribution system it in uneconomical to upgrade existing network for improvement of power factor.In weak grid system residential consumers use voltage stabilizers to cope up with poor quality of voltage, while industrial consumers use switched capacitors. But voltage stabilizers regulate the voltage on cost of drawing more current from system. On the other hand switched capacitors technology is not robust enough to handle instant variations in power demand. Low power factor on local grid systems can be addressed using static var compensators. In this paper designing of SVC for local grid system is discussed.
