EGC receiver using single radio frequency chain and single matched filter over combined rayleigh and rician fading channels

Zachaeus K. Adeyemo and Isaac A. Ojedokun

Mobile satellite communication (MSC) system has become an essential part of the world telecommunication infrastructure. However, it is characterized by multipath fading effects. Equal Gain Combining (EGC) which was one of the techniques previously used to address this problem also suffers from hardware complexity. A modified EGC (mEGC) with single radio frequency chain and single matched filter was developed to mitigate the effects and reduce the hardware complexity. The performance of mEGC was evaluated using Bit Error Rate (BER) and the processing time. The results at mobile speed of 120 km/hr and signal-to-noise ratio (SNR) of 6 dB; BER of 0.0063, 0.0503, and 0.0693 were obtained as against 0.0114, 0.0504, and 0.0695, for the conventional EGC with 4QAM, 16QAM, and 64QAM, respectively, also, the processing time of 0.0313s, 0.0156s, and 0.0157s were obtained for mEGC as against 0.0469s, 0.0469s, 0.0417s respectively for convectional. The modified EGC receiver gave approximately the same BER performance when compared with the conventional EGC receiver and thus reduced hardware complexity.

Norzilah Musa, Siti Z. Z. Abidin and Nasiroh Omar

In networked collaborative working environment, users are involved with either repeatable or exclusive task. These variety tasks required the collaborative system to support it dynamic and creative solutions especially in sharing the communication media. Most of the related research is objectively focusing on the alignment of user behavior in shared activities. There is not much research conducted concerning on sharing communication media components in creative collaborative activity in details. In this paper, we analyze collaborative work application systems focusing on the communication module in four common areas; business, health, education and manufacturing. Based on the analysis, communication media sharing elements are formed into three layers. In each layer, media sharing element and its functions are identified. Then, we proposed a general software framework for communication media sharing for creative collaborative activities. The framework is functioning as a platform for users to manage their dynamic creative solutions to accomplish complex task.

An exploratory study on blind users’ mental model in computer accessibility

The growing needs in the area of HCI has led to many new researches focusing on user-centric design, investigating the problems faced by a computer user and ways to produce an effective yet efficient design. Often, designers need to acquire the knowledge and the experience of the users to produce a good interface design. This can be referred as a wise exploitation of user’s mental model. The paper serves as a preliminary study which explores the mental model of blind users as a contribution in improving the accessibility of computer applications. Based on the blind user’s perception, imagination and interpretation, the study indicates that touch sensation plays an important role in improving the representation of a computer application to them. Associating touch sensation with information familiar to the blind users enhances the learning process.

Zhang Qin, Huang Xiaoqing and Liu Wenbo

Abstract:

Fractal coding has been proved useful for image compression, and it is also proved effective for image retrieval. In the paper, we present a statistical method called variable bandwidth kernel density estimation to analyze fractal coding parameters. Then retrieve images using the retrieval index constructed with this method. Experimental results show that the proposed method with a variable optimized bandwidth performs better than those with a fixed bandwidth and the histogram method both in retrieval rate and retrieval speed. In this paper, the Average Retrieval Rate (ARR) can reach 72.40%, which is more than that obtained by the existing methods.

Descriptive statistics was chosen as a technique to evaluate the mean and reliability of attention attribute; perceptual arousal (PA), inquiry arousal (IA) and variability (V) inside the proposed integration model to achieve the student attention in education environment.

Design of linear polarization antenna for wireless MIMO application

K.A.Abd. Rashid, M.N. Husain, A.R. Othman, M.Z. Abd.Aziz, M.M. Saad, M. Senon, M.T. Ahmad and J. S Hamidon

This paper presents the design of the linear polarized antenna for wireless MIMO communication system. It is impossible to fulfil the demand of the wireless communication system due to limitations in channel capacity on single input single output (SISO) systems. Multiple input multiple output (MIMO) system has become a famous research field for the next generation wireless communication system in order to overcome this problem. Since polarization diversity is effective to avoid the fading loss caused by multipath effects, therefore, polarization diversity becomes one of the most important techniques that can be used to enhance MIMO system performances. It can be utilized to improve the communications channel capacity and utilize the frequency spectrum with frequency reuse technique. Therefore, the development of linear polarized antenna is significant in order to improve the wireless MIMO system performance based on polarization diversity technique. Polarization diversity can be utilized to double the frequency spectrum to realize frequency reuse and improve the communications capacity. This project is to design an antenna that can provide linear polarization to reduce the signal losses.

Deployment of optimized algorithm for mpeg-4 data over wireless multimedia sensor network

Abstract:

Typical Wireless Sensor Network (WSN) always deals with scalar data such as temperature. These types of data are suitable for low rate networking technology such as IEEE802.15.4. Transmitting a video for IEEE 802.15.4 raised other challenges for bandwidth limited sensor networks like WSN. The optimization method able to determine the optimal limit for quantization scale, group of picture and frame per second in order to suit the WSN environment. Changing these parameters affects the bandwidth requirement and video quality in term of Peak Signal to Noise Ratio (PSNR). This project aims to create an embedded code in TelG mote according to this concept. Results from experiment show improvements in packet delivery ratio of 28% for Akiyo qcif file, 27% for Foreman qcif file and 9% for Mobile qcif file. This work proved that the method has successfully increased the network performance.

Positioning of antenna to locate PD in power transformer

Irfan Ali Soomro and M N R Baharom

Abstract:

Partial discharge (PD) online monitoring is an effective tool of examining the conditions of insulation and detecting faults in power transformers. From literature it is acknowledged that, the PD detection is not adequate to take a decision about intervening, so the location of fault is necessary to evaluate the hazard to corrective actions. The aim of this experiment is to determine the location of antenna to obtain the strong PD signal. The method used is an experimental work in the laboratory. A sample of two antenna model is made, one antenna is considered as a PD source (transmitting antenna) and other is used as a receiver. The height of transmitting antenna is kept at 25cm. Measurements have been taken by changing the distance between antennas from 15cm and 30cm and also varying height of receiving antenna from 3cm to 45cm. After analyzing the results, it is found that the strong signal has been received when receiving antenna’s height is same as transmitting antenna. Otherwise receiving antenna catches weak signal if the height of receiving antenna is lower or higher than 25cm. It means that the receiving antenna only received strong signal when both antennas are face to face with each other. It is concluded that many antennas must be used for locating the PD source. So that PD location can easily be found and can perform necessary actions on it.

Approximation of the starting time of radial flowregime under variable wellbore storage conditions in vertical wells

Freddy Humberto Escobar, David Alexander Olaya and María Victoria Medina

It has been observed that wellbore storage changes either increasingly or decreasingly when a well test is run in a producing hydrocarbon well. It causes alterations of the time at which radial flow initiates which normally takes longer time than in wells with constant wellbore storage. This also leads to difficulties in establishing the actual radial flow regime and therefore the interpretation may not be accurate. So far, only for cases of constant wellbore storage the starting time of the radial flow regime can be predicted. In this work, the available mathematical modeling was used to simulate pressure tests with variable wellbore storage to study their behavior so empirical expressions were developed to estimate the starting time of the radial flow regime when wellbore storage is no longer constant. The expressions were validated using synthetic examples.

Performance and emission characteristics of citronella oil in single cylinder diesel Kirloskar engine

J. Rajesh Kumar, S. Prabhakar and Kiran Raj

India imported about 2/3rd of its petroleum requirements which involved a cost of approximately Rs. 80, 000 crores in foreign exchange. Even 5% replacement of petroleum fuel by bio-fuel can help India save Rs. 4000 crores per year in foreign exchange. The country has been hit hard by the increased cost and uncertainty and so is exploring other energy sources occurring bio-diesel extracted from trees is one such alternative under consideration. Bio-diesel would be cheap to produce as it can be extracted from certain species of tree that are common in many parts of India. However, as the biodiesel is produced from vegetable oils and animal fats, there are concerns that biodiesel feedstock may compete with food supply in the long-term. Hence, the recent focus is to find oil bearing plants that produce non-edible oils as the feedstock for biodiesel production. Citronella oil is used as a input for biodiesel production via transesterification. Diesel fuel is much higher use than any other gasoline fuels because diesel engines have many adaptable domestic uses like small irrigation water pumbing systems, light weight four/two seated auto cab and car engine small electricity generators etc. Citronella biodiesel fuel properties are observed and tested in the fuel testing laboratory with standard procedure. Then an experimental set up is construct to study the performance of a small Kirloskar Diesel in the internal combustion engine by using different blends of Citronella Oil based biodiesel under different Operation Conditions. We have to determine the optimum performance of this citronella biodiesel. NOx emission from the test engine can be measured by chemical luminescent detector type NOx analyser.

Analysis and simulation of isolated wind diesel hybrid power system

The present day energy scenario clearly shows the large potential demand for the electrification of remote rural places which can be met easily through the stand alone renewable energy systems. The hybridization of these stand alone renewable energy systems increases the reliability of self sufficient power supply for off grid locations [1]. This work describes the characteristic features of a standalone hybrid Wind-Diesel microgrid. The modelling and simulation of a standalone Wind/Diesel system with individual system components i.e., Diesel Set and Wind Set are simulated and described in detail. The effect of penetrative variations with change in wind speed and the impact of position and length of transmission line on reactive power compensation in the microgrid are effectively demonstrated by simulation results.

Prospects and challenges of composites in a developing country

Haruna V.N, Abdulrahman A.S, Zubairu P.T., Isezuo L. O, Abdulrahman M. A and Onuoha D.C.

In spite of the tremendous progress that has been made in the discipline of material science and engineering, there still remain technological challenges, including the development of even more sophisticated and specialized materials such as composite materials. This research is geared towards exposing the prospects and the drawbacks of the development of composite materials. The review of literatures shows the trends of composite materials in the developing countries. The most important advantages of composite over the conventional steel are light weight, corrosion and fatigue resistance, high stiffness and strength. The equipment to adopt this technology is rarely available in some developing countries. A challenge for future growth is the simulation of technology upgrading and dynamism through technology transfer. Most developing countries desire rapid industrialization, export enhancement, self reliance and minimizing the import in order to achieve a robust economy. However, strengthening the link between research institutes and industries will contribute immensely to the development of composites in these countries and also add to the participation in the composites market.

Development and performance analysis of a domestic solar still

A. Iqbal and M. Ahmad

Potable water is a basic need for the habitants of an area. In Pakistan, almost 53% of total population does not have access to safe and sufficient drinking water because of brackish/saline water. The brackish/saline water could be economically desalinized by solar desalinization (distillation). To solve this problem, a solar still was designed, fabricated and installed at Agricultural and Biological Engineering Institute, National Agricultural Research Centre, Islamabad. The solar still was developed with mild steel sheet having 2 m² area, the inlet water depth was kept 2 cm, angle of glazing (glass) was kept 15⁰, and the basin base was painted black to absorb the solar radiation. The performance of the solar still was evaluated from June to December, 2011. The parameters measured/calculated were: ambient temperature, inlet water temperature, vapours temperature, basin water temperature, basin temperature, wind speed, solar radiation, and productivity (output) of the solar still. The average daily productivity of the solar still for months of June, July, August, September, October, November, and December was 5738 ml, 3937 ml, 2637 ml, 1837 ml, 2082 ml, 1620 ml, and 1510 ml, respectively. The productivity of the solar still was higher during the month of June (5738 ml) as compare to its productivity during the month of December (1510 ml), this was because of higher solar intensity during the month of June. The average productivity of solar still from June to December was 3000 ml and the overall efficiency was 22%. The average cost of desalination was predicted Rs 3.9 per litre.

Jonathan Romero C., Jorge I. Chavarro, Alan Garrido and Helmer A. Guzman

This paper presents a new methodology for evaluating the performance of irrigation systems, taking into account indicators of efficient use of water resources and tools for intelligent systems such as fuzzy logic. The objective was to propose a fuzzy logic system as a tool to evaluate the performance of irrigation systems, from a set of indicators of efficiency of water use. The system was validated for the cultivation of cocoa (Theobroma cacao) in the climatic conditions of the north part of Huila state, Colombia. Treatments (T) were: T1: drip irrigation, T2: surface irrigation, T3: control without irrigation. The experimental design was completely randomized block with three replicates per treatment. The Fuzzy Logic Toolbox of Matlab (MathWorks) was used to implement the fuzzy logic system. The output variable of the system was the performance of the irrigation system (%) and the input variables were index rate income from irrigated area cultivated ($ ha^-1) and the Relative water supply. The results of the study show that cocoa cultivation and under the climatic conditions of the north of Huila, the technique of surface irrigation performance has a "High" (91.3 %), on the contrary treatment without irrigation presents a performance "Low" (17 %) and drip irrigation has a performance "Medium" (50 %). This type of system as implemented in the agricultural sector and specifically in the evaluation of irrigation systems tools are innovative and can help decision making of professionals in such sector.

K. Muthukumar, S. Jayalalitha and S Hari Charan Cherukuri

This work aims at minimizing the power loss in radial distribution system by placing optimally sized shunt capacitors at appropriate locations in the proposed test system. The power flow solution of the proposed test network is obtained using Backward/forward sweep based load flow methodology for different types of load models. The rating of the capacitors to be placed in the test system is optimized using artificial bee colony algorithm which is a nature inspired Meta-heuristic search technique mimics the foraging behavior of the honey bee swarm. The sensitive nodes which are prone to voltage collapse are identified for installation of the shunt capacitors by voltage stability index computation. The rigidness of the proposed optimization approach searching towards the optimal solution is tested on IEEE 69 bus radial test distribution system for different load models.

Relationship for slots width, antenna directivity, and the 3dB HPBW of an RLSA antenna at 12.4 GHz using regression analysis

S.Z Iliya, T.A Rahman and Y.A Abdulrahman

The quest to optimize performance of the radial line slots array (RLSA) antenna continued to unfold. Attempt is made at studying slots width variation in radial line slot array antenna (RLSA) and its effect on the 3dB half power beam width (3dB HPBW) in this submission. It is aimed at formulating a polynomial equation that best describes the relationship between them. The polynomial equation in turn relates to the directivity of the RLSA antenna. The minimum number of slots in the first ring were restricted to (n1) =12 and, (n1) =14, this is used to manipulate slots concentration on the radiating surface. The restriction is owed to the fact that much cluster of slots in the first ring resulted to a deteriorating performance in terms of directivity values recorded from CST 2012 simulations, for the 12.4 GHz regression analysis in this study. Results obtained from the polynomial equation formed were compared with measured and simulated directivity values and showed good agreement.

Performance evaluation of self organization protocols using AODV routing protocol

A. Maizate, N. El Kamoun and M. Agnaou

Recent advances in wireless sensor networks have led to many new protocols for self organization specifically designed for sensor networks where energy awareness is an essential consideration. It is one of the major research areas in computer network field today. The WSN has important applications such as disaster management, combat field reconnaissance, border protection and security surveillance. Sensed data need to be delivered to the base station using multihop and must cope with the network unreliability problem and the energy consumption. For minimum energy consumption, all the steps from node deployment to network architecture (Clustered Network) and from environment sensing to communicating the sensed data to base station (routing) should carefully be designed. Few routing and self organization protocols take into consideration of these problems. It is a great challenge of the hierarchical self organization protocols to provide network survivability through redundancy features. In this paper, a short literature review of the existing self organization protocols and routing protocols are carried out. Then, a comparison of self organization protocols was performed using a reactive routing protocol, Ad hoc On Demand Distance Vector (AODV). This comparison addresses network survivability and redundancy issues. Finally, conclusion was drawn based on the research and future direction for further research is identified.

Alternatives to natrosol as thickener in the production of emulsion paint

Akpa Jackson Gunorubon and Uku Misel

Alternative thickeners to an industrial thickener (natrosol) in the production of emulsion paints were investigated. Four starch grades; native starch, native starch modified with sodium acetate, native starch modified with sodium acetate plus fumaric acid and native starch modified with sodium acid mixed with adipic acid were tested as possible alternatives to natrosol. The physio-chemical properties such as viscosity, density, pH, drying time and durability of the paints produced with these starches as thickeners were compared with paint produced with the industrial thickener (natrosol). There were improvements in these properties in paints produced from the modified starches compared with paint produced from the native starch. The paint produced with native starch modified with sodium acetate and furmaric acid had properties closest to the paint produced with the industrial thickener. The viscosity, density, pH and drying time of the paint produced with sodium acetate and furmaric acid are 61cp, 1.53g/cm³, 8.43 and 26mins compare to 60cp, 1,54g/cm³, 8.5 and 25mins for paint produced with the industrial thickener. All paints produced with alternative thickeners deteriorated in properties with time (when observed after three weeks of storage).

Rehabilitation device is used as an exoskeleton for peoples who had failure of their limb. Arm rehabilitation device may help the rehab program to who suffered with arm disability. The device is used to facilitate the tasks of the program and minimize the mental effort of the user. Electromyography (EMG) is the techniques to analyze the presence of electrical activity in musculoskeletal systems. The electrical activity in muscles of disable person is failed to contract the muscle for movements. To minimize the used of mental forced for disable patients, the rehabilitation device can be utilize by analyzing the surface EMG signal of normal people that can be implemented to the device. The objective of this work is to model the muscle EMG signal to torque for a motor control of the arm rehabilitation device using Artificial Neural Network (ANN) technique. The EMG signal is collected from Biceps Brachii muscles to estimate the elbow joint torque. A two layer feed-forward network is trained using Back Propagation Neural Network (BPNN) to model the EMG signal to torque value. The performance result of the network is measured based on the Mean Squared Error (MSE) of the training data and Regression (R) between the target outputs and the network outputs. The experimental results show that ANN can well represent EMG-torque relationship for arm rehabilitation device control.
