Title: Kinematic modeling for PID position control of a new three-fingered robotic hand
Author (s): K. Nasir, R. L. A. Shauri, N. M. Salleh and N. H. Remeli
Abstract:

A new design of a three fingered robotic hand has been developed and verified for a grasping task based on a set of predetermined angle position. However, the robotic hand has limitation in integrating measurement from external sensors to create its own 3D position vector’s trajectory. Therefore, it is required to create a new mathematical kinematics equation for the hand that relates between the direct joint angles and the position vector of the finger-tip in order to produce motion based on Cartesian coordinates. The study derived the kinematics based on the joint and link dimensions of Finger 1 and 3 using geometrical approach due to their different styles of motion. Simulation results verified the correctness of the equations where the proposed inverse kinematics has correctly converted the position vector of tip-end to the required motor angles of each finger joint. Consequently, the kinematics is verified to be able to provide the angle references for the position control of the motors in real-time experiment according to the varied fingertip positions. The output of this study is beneficial to the robot control when trajectory needs be generated based on sensor information. Besides, individual control of separate finger joints between the fingers could increase the grasping flexibility and be a good reference for the development of the robot arm in future study.

Abstract:

A series of experiments have been conducted in order to determine the optimal concentration of polyvinyl alcohol (PVA) for deposition of electrochromic nickel hydroxide films onto fluorine-doped tin oxide (FTO), using cathodic template deposition method. Fundamental physicochemical properties of electrolytes for cathodic template deposition method with different concentration of PVA have been studied. It was found that higher concentrations of PVA resulted in higher adhesion of films to FTO substrate and higher performance; however, excessive concentrations resulted in degradation of film performance. It was also found, the electrolyte viscosity is directly dependant on PVA concentration, however, no correlation between PVA concentration and conductivity have been found. A hypothesis was proposed to explain such behavior.

Author (s): Raed S. Al-Wasify, Alaa K. Mahmoud, Samar R. Hamed, Israa E. Abdelaziz and Shimaa R. Hamed
Abstract:

Untreated slaughterhouse wastewater contains high concentrations of organic matters, suspended solids, and pathogenic microorganisms which have destroying effects on the environment. Thus, slaughterhouse wastewater should be treated properly before discharging into the environment. A pilot model was installed that consisted of three treatment stages; bioadsorption, coagulation and aeration. The first stage used Moringa oleifera seed husks and pods as a bioadsorbent. The second stage used M. oleifera seeds extract as natural coagulant and followed by the third stage (aeration stage). M. oleifera seed husks and pods proved a good ability to remove total suspended solids (TSS), total bacterial count (TBC), total coliforms (TC) and Escherichia coli, without significant removal of organic matters. A significant increase in organic matters represented in chemical oxygen demand (COD), biological oxygen demand (BOD), total Kjeldahl nitrogen (TKN) and total phosphorus (TP) concentrations after the coagulation stage. The aeration stage succeeded to remove this occurred increase in the coagulation stage. The overall average removal percent after aeration stage were 95.68%, 95.89%, 70.15%, 82.98%m 83.91%, 90.49%, 90.58% and 88.66% for COD, BOD, TSS, TKN, TP, TBC, TC and E. coli, respectively. The obtained results indicated the suitability of using M. oleifera seed husks, pods, and extracts in slaughterhouse wastewater treatment.

Abstract:

Domestic refrigerator is used in almost every household for preserving food, cooling water, freezing ice and many more. This research is done on a domestic refrigerator which is powered by solar panel. It is an attempt to analyze the effect of COP on a refrigerator. This experiment is conducted on a domestic refrigerator in which extra D.C. axial fans have been fitted in the back panel of refrigerator and these extra fitted fans cool the condenser faster than that of without fan. Therefore, the heat transfer from the condenser is more. In this experiment it is found that average coefficient of performance (COP) of domestic refrigerator with D.C. axial fans is higher than that of without D.C. axial fans by 0.038 in the studied range. This increment in COP is obtained due to the extra fans fitted in the back panel. It is also observed that the refrigeration effect (RE) of refrigerator with fan is about 7.02% higher than that of without fan.

Title: Finite element analysis of reinforced concrete deep beams strengthened in shear with CFRP
Author (s): Ahmed Abdullah Mansoor, Wisam D. Salman and Ali Lafta Abbas
Abstract:

A paper presents a numerical analysis using ANSYS finite element program to develop a model for expecting the performance of seven lightweight aggregate reinforced concrete deep beams with 28 days compressive strength 26MPa and density of 1950Kg/m3 strengthened in shear by externally bonded CFRP. All beams have same dimensions (150mm width, 400mm depth and 1400mm length), longitudinal steel reinforcement ratio p=0.0115 and shear steel reinforcing Φ5@100mm. CFRP strips 50mm width are used for strengthening. The effective variable parameters were: a/d ratio, CFRP spacing, orientation and number of layers. The results obtained from the ANSYS finite element model got good agreement when compared to the experimental results [1] which were done for the same deep beams with the same material properties, internal reinforcement and strengthening schemes. The results show that the ultimate load and deflection predicted by numerical analysis is less than experimental results by 9% and 5.7% in average respectively. By using CFRP strips in shear strengthening, the ultimate load has increased by 18%, 13.6%, 32% and 27.3% for vertical, horizontal, inclined and double vertical layers, respectively for a/d=1. For a/d =0.8 the increase is 10% for vertical strips. It is recommended that the CFRP is placed such that the principal fiber orientation is either normal to the longitudinal beams axis or normal to the line joining the applied load and supports (strut path) to resist higher tensile stresses and strains distributed along it.

Title: Experimental evaluation of the energy performance of a photovoltaic generator in a process of optimization of mechanical compression refrigeration
Author (s): Adingra Kouassi P. A., Toure Siaka, Traore Diakaridja and Wanignon Fassinou F.
Abstract:

The design of a photovoltaic generator is generally obtained from the energy characteristics of the solar collector and from the daily light energy that falls on its surface. The optimization of this design depends essentially on the daily sunshine rate, the size of the photovoltaic generator and the energy behavior of the associated load. This article proposes an optimization of the performances of a photovoltaic generator through a concrete evaluation of the capacity electrochemical battery to install for the supply of a 150-liter DC refrigerator. In an experimental study, we characterized the solar energy potential of the city of Abidjan (Côte d'Ivoire-West Africa) and evaluated the energy performance of a photovoltaic generator (250 Wp/100 Ah) linked to a mechanical compression refrigerator. The results showed a mean daily irradiation between 3.5 and 5 Kwh/m2 for 6.5 hours of average insolation per day and a maximum photovoltaic energy production of 48 Ah/d of the solar panel. We obtained a maximum daily consumption of 30 Ah over a cumulative period of 12 hours of operation of the motor-compressor. The balance between production and consumption has confirmed a surplus of energy generated by the solar panel that can reach 45 Ah in front of an energy demand of the motor-compressor between 4 and 8 Ah, during the period of insolation. This experimental approach allows for an improved planning of the capacity electrochemical battery to install in photovoltaic solar refrigerators.

Title: MMF based fault-ride in distribution networks
Author (s): C. Malathi and Siddappa Naidu

Abstract:

Accurate location of the fault in the line of a distribution network using mathematical morphological filtering technique is implemented in the paper. Different sorts of methods have been proposed for FL in distribution systems. FL methods can be grouped into three: (i) impedance-based methods (ii) traveling wave-based methods and (iii) methods based on neural networks. The Estimation of the fault distance by relating apparent impedance with the pre-known line data is done. The results location accuracy decreases due to the application of distribution networks with some laterals, sub-laterals, and load taps. Traveling wave-based, in contrast, is an FL method which is been widely used in transmission lines. Classification of methods based on wave-head identification, characteristic frequencies, single-end, two-end, and multi-end. Morphological filters such as dilation-erosion difference filter, Open Close-Close Open filter and Close-Open Difference Filter used in MM is utilized for the of accurate and fast detection of the fault location. The simulation studies are performed in MATLAB environment and voltage/current waveforms obtained at different nodes are transferred to MATLAB and analyzed by using MM for the exact location of the fault. and to analyze the impact on the detection of the fault. MM is the time domain approach for the above-said objective whose simplicity and accuracy are the attractive feature for fault location in power system signal.

Title: End-Length-offset influence on the bending rigidity of linear tapered T-Beams
Author (s): Myriam Rocio Pallares M., Maria Fernanda Cabrera Silva and Karen Melissa Diaz Rojas
Abstract:

In this study, a calculation system in Maxima (GNU) was implemented, based on the numerical integration of the flexibility parameters to obtain the elements of a T-beam stiffness matrix with linear haunches including zones of infinite rigidity (rigid end off-sets) and shear/axial deformations. The length of these zones is assumed as half the width of the beam-column joint. The goal is to demonstrate that, an analysis based on the geometry between centroidal axes without considering joint stiffness, tends to exhibit greater flexural strength, overestimating the lateral deformations, which can be important when calculating the lateral displacement of frames. The flexural rigidity parameters of a T-beam with and without zones of infinite rigidity were determined through the calculation of the flexibility integrals using the three-point Gaussian quadrature rule of integration. Increases in stiffness (%) were determined when rigid end off-sets were considered.

Title: Experimental investigation of cylinder deactivation impact on engine performance and emission for SI engine
Author (s): N. A. Abas, N. Tamaldin and A. K. M. Yamin
Abstract:

Cylinder deactivation is one of the promising fuel efficiency strategy that offers lower fuel consumptions and exhaust emissions by allowing the multi-cylinder gasoline engine running with smaller engine displacements at part load operation. Cylinder deactivation technology has been developed by several vehicles manufacturers and extended to as large as 6.5l V12 engine and as low as e3.5l V6 engine. Only few manufacturer has developed a 1.4 liter inline, 4-cylinder engine which is Volkswagen TSI Polo BlueGT. This is because the effectiveness of the cylinder deactivation concept depends on the power to weight ratio, engine balancing, and other factors. However, in this study an effective cylinder deactivation system is implemented for smaller engine displacement. The aims of this study are to investigate the potential of cylinder deactivation strategy for small SI engine with 1.3 liter in improving the fuel economy and emission at part load. The skip fire cycle method was applied to cylinder deactivation strategy using a relay-based system which was built to enable the manual control of ignition and injection for each cylinder. The effectiveness of the skip fire cycle method is measured at steady state for fuel consumption, emissions and vibration. To verify the feasibility and effectiveness of the skip fire cycle, a manual CDA was developed and set up to a research vehicle. The measurements show the improvements of fuel consumptions and exhaust emissions at the expense of the engine power loss and vibration. The results show the CDA strategy could be successfully implemented to small displacement engine with an improvement of the fuel consumption and emission.

Title: Determination of the PV module surface temperature based on neural network using solar radiation and surface temperature
Author (s): Aiat Hegazy, E. T. El Shenawy and M. A. Ibrahim
Abstract:

Photovoltaic (PV) energy is widely used over the world as the main step to solve the electricity shortage problems. Also, in remote and rural areas the use of PV systems can be considered the most important and more efficient source of electricity for different domestic applications and water supplying systems. Since the performance of any PV system is directly influenced by weather data such as ambient temperature or solar radiation, the accurate estimation of these parameters is essential for good design and operation. Different attempts have been carried out to determine the PV module surface temperatures using mathematical models of the PV module, empirical formula and by neural networks. Neural network (NN) doesn’t require any analysis of the system or scientific details; it only needs data from the system for training purposes. The present research describes the estimation of the PV module surface temperature using NN based on measured ambient temperatures and incident solar radiation. The NN is composed of input layer with two inputs (solar radiation and ambient temperature), hidden layer that has eight neurons and output layer to estimate the PV module surface temperature. Error back propagation algorithm was used to train the NN based on the measured data pairs at various working conditions. The result showed that, the estimation accuracy of the PV module surface temperature by the NN reached more than 96% of the measured value for clear and sunny days.

Title: A fuzzy approach for grammatical analysis of English text
Author (s): V. Ramaswamy and J. Sangeetha
Abstract:

True grammar checking of a language is more complex. One can mark to some extent a whole appropriate grammar for a natural language, but there is generally variety of exceptions in genuine practice that a formal grammar is of negligible help in writing a grammar checker. The most significant parts of a grammar checker of a natural language is a dictionary of complete set of the words in that particular language, accompanied with the part of speech of each word. The fact that all the words can obtain many different parts of speech significantly enhances the complexity of every grammar checker. The proposed work is based on the natural language processing for Grammatical Analysis of English Text. The work has the base idea of the syntactical and the grammatical analysis of the English text by tokenization without the use of the trained data sets. Grammar checking without the data set is the main advantage of the proposed system where in the new patterns can be added to the system without any training to the system.

Title: Enhancement the turbulent heat transfer by using finned converging-diverging nozzles
Author (s): Khudheyer S. Mushatet and Zahraa K. Ali
Abstract:

The present work shows the effect of insertion converge-diverge conical-nozzle turbulators fitted with triangle fins inside a heated circular pipe on turbulent flow heat transfer, friction and overall performance index. The study is performed experimentally for turbulent flow system with use of air as a working fluid for a range of Reynolds number between 10000 to 50000. The conical nozzles integrated with triangle fins are utilized as turbulators to generate more complex mixing flow along the pipe wall. The plane conical nozzles turbulators are used for three various pitch ratios (Pr=1.0,1.5 and 2), and those fitted with triangle fins are tested at pitch ratio Pr=1.0 with two various area ratios of 0.064 and 0.149 respectively. The heat transfer of conical turbulators integrated with triangle fins is enhanced by 274% as compared with plain pipe and 55% as compared with inserted conical nozzle turbulators alone for the larger area ratio (Ar =0.149). In the addition, the Conical nozzle turbulators fitted with triangle fins give optimum overall thermal performance as compared with unfinned conical nozzle turbulators and plane tube.

Abstract:

In this article, the results of a Creep and Relaxation studies in asphalt mixtures are presented. Initially, a description of the conceptual model of the material and the details of the viscoelastic characterization in asphalt mixtures using the Creep test are shown. Then, the Creep phenomenon is represented using a generalized Kelvin model with calibrated parameters [9]; also the relaxation model is developed using the direct and inverse transformation of Carson Laplace. For the modeling process of the two phenomena, a symbolic calculation code was programmed using MAXIMA-CAS and Maple software. Finally, we conclude that the generalized Kelvin rheological model fits the Creep laboratory data, and, the calculated relaxation function simulates the phenomenon correctly. This function was also compared with the approximate analytical model of Schapery (1965) and the result data were satisfactory.

The dataset involved processing of two band wavelengths: Alpha (8-12 Hz) and Beta (12-22 Hz) to derive appropriate results and to analyze theoretical and practical level and to keep a track of appropriate changes that occur in the waveform. To ensure repeatability of results so as to enhance the performance of the subjects to increase attention level and practice the task, experiment protocol was finalized. Our experimentation and analysis show that the results of the experiment and numerical investigation have a good correlation to the analysis of EEG Data. This paper concludes with the remarks on the Alpha and Beta waves of the selected electrodes and the comparison between each subject to show that these tasks did have an overall positive effect.

Title: Multi nozzle parallel to improve efficiency cross flow turbine
Author (s): Corvis L. Rantererung, Titus Tandiseno and Mika Malissa
Abstract:

Cross flow turbine is a rotating device that takes energy from the flow of water emitted through a nozzle. Energy potential water can be converted into kinetic energy on nozzle of water turbine . A stream of water coming out from a nozzle that has a high speed hits the turbine blade. After hitting the blade the direction of the flow velocity changes so that a momentum changes which results in the turbine runner spinning. The impulse turbine is the same pressure turbine because the flow of water coming out of the nozzle is the same as the surrounding atmospheric pressure. All high energy places and pressures when entering the turbine road blade are converted into speed energy. The use of parallel multi nozzle is very effective to improve the performance of cross flow turbines as a driver of electricity generation.

Title: Novel fault detection on three-phase transmission line using modified artificial neural network with wavelet based analysis
Author (s): M. Nithyavelam and Siddappanaidu
Abstract:

Fault type identification and fault distance calculation are the major phases of reliability improvisation in power transmission in terms of fault restoration. This paper proposes a novel approach for fault discovery of three-phase double transmission line, which is primarily based upon the Discrete Wavelet Transformation (DWT) and Modified neural network algorithm. The proposed identification requires double side three phase measured values of transmission current and voltage also considers the shunt capacitance. Three phase currents of most effective one end are measured and discrete features are extracted using discrete wavelet transform. Those features are then used as inputs to the modified neural network algorithm. The training data set for modified neural network algorithm is obtained by way of simulating the ten extraordinary kinds of faults the use of diverse values of fault inception angles and fault resistances, so that the accurate consequences may be received. The proposed modified neural network algorithm employs twenty inputs and best one output for classifying the faults. The distinctiveness of the proposed approach is that all the features, inputs used in developing the algorithm are normalized, in order that the approach may be used for any system with none significant changes. The simulation of the Three-phase transmission line network and discrete wavelet Transformation analysis are achieved inside the toolboxes of MATLAB® and modified neural network algorithm codes also are written in MATLAB®.

Title: Qualitative comparisons of elicitation techniques in requirement engineering
Author (s): Olatunji J. Okesola, Kennedy Okokpujie, Rowland Goddy-Worlu, Afolakemi Ogunbanwo and Olamma Iheanetu
Abstract:

It is often emphasized that the quality of elicited requirement is mostly influenced by the elicitation techniques employed to gather software requirements. Many elicitation techniques have been presented in requirement engineering but they are hardly adopted in practice as the available empirical and comparative evaluations are inadequate to guide the software industry on which technique is better. Classifying a selection of seven requirement elicitation techniques as collaborative, individual or contextual, this study compares the popular techniques using two groups of qualitative criteria - terms of information collection and quality of feedback information. The evaluation results are tabulated and the findings are depicted by spider diagrams. The study concludes that each technique has its strengths and weaknesses, the factors software engineers should weigh when selecting appropriate techniques for requirement elicitation.

Title: RMS current based passive islanding detection of DG using adaptive linear neural network
Author (s): Anu Radha and Shimi S. L.
Abstract:

Distributed generators (DG) are gaining more attention in present century due to reliability and better power quality. With the increase in the use of DG, the nature of distribution is changing which causes technical issues. One of these issues is related to islanding detection. A real-time islanding detection based on ADALINE and d-q Theory is proposed in this paper. Five ADALINE neural networks are used to evaluate RMS current in d-q frame and one of these ADALINE is used to evaluate the phase angle in d-q frame using phased-locked loop (PLL). Change in RMS value of current is compared with threshold limit to detect islanding. Islanding detection unit is used to send a trip signal to DG side circuit breaker to disconnect the DG from load in case of islanding. Simulation results are validated using the real-time HIL OP4510 at different load conditions.

Title: ASH hole variation in rice husk biomass furnace with parallel flow heat exchanger to drying box temperature
Author (s): I. Gede Bawa Susana, I. Made Mara, I. Dewa Ketut Okariawan, Ida Bagus Alit and I. G. A. K. Chatur Adhi Wirya Aryadi
Abstract:

The process of drying food ingredients naturally has an impact on the low quality of the products due to the non-optimal drying temperature. Moreover, in the rainy or cloudy day, the drying process cannot be carried out. In addition, for the rural communities, the drying process that is done automatically or using mechanization is difficult to be done because of the high operational costs. In this way the method of conversion of rice husk biomass energy using a furnace equipped with ash holes and heat exchangers are placed inside the furnace. The results of this research revealed that on several furnace ash hole diameters were found that the larger the hole diameter of the ash hole is directly proportional to increase the drying box temperature. For the ash holes with a 12 mm in diameter, the mean temperature and highest temperature of the drying box were 72.79oC and 109.20oC respectively.
