A Computer-Based Comparative Performance Analysis of QPSK and 4-QAM Schemes in Fading Channels[ ]


Amongst the industry trend of modulation schemes are the QPSK and QAM schemes. The 4QAM scheme is one of the categories of QAMs, and is an equivalent of the QPSK scheme in terms of number of information bits transmitted per symbol. In this research, not only are the two schemes compared in Rayleigh and Rician fading environment, comparison was also made to find out the BER performance differences of each scheme in the fading channels by applying SNR/BER as key performance indicator. With a design modeled in Simulink for this purpose, various instances of simulations were run and the resulting values of SNR/BER over different time period recorded for QPSK and 4QAM in the fading channels. By ensuring proper signal alignment and comparing the experimental product of SNR and BER with the theoretical expression SNR x BER = 1, the data set obtained and thus, the results are considered reliable. Findings show that 4QAM is generally a better modulation scheme but, is preferable in Rayleigh fading channel at the cost of transmission stability. It was also established that QPSK is an ideal choice in Rician environment than it is in Rayleigh fading environment

Performance Study of an Aero-Derivative Gas Turbine System with a Coalescer Filter at Varying Operating Conditions[ ]


The performance of an aero-derivative industrial gas turbine (ADIGT) with a coalescer filter at varying operating conditions is presented. The study determines the aptness of an ADIGT for power generation in two extreme locations. The ADIGT was modeled to operate at conditions of Usan offshore oilfield and Maiduguri desert in Nigeria. For all operating conditions of decrease TET, corresponding decrease in AFR was observed. For ambient temperatures between 15 and 38OC in both environments the AFR, OPR, and IPD declined to above 0.5 %. Equally, for conditions below ISO and 1.8 % drop in TET, a 2.4% loss in AFR and 1.6% gain in OPR were attained. The estimated IPD and AFR values exist at about 90% validity with the experimental. However, for ADIGT to be suitable for power generation in these locations, it will require system modification and the use of inlet air pre-cooling system to bring the ambient air close to ISO.

The XPS, depth profile analysis and photoluminescence studies of pulsed laser deposited SrAl2O4:Eu2+, Dy3+ thin films prepared using different laser fluencies[ ]


SrAl2O4:Eu2+, Dy3+ thin films were grown on silicon (Si) (111) substrates using the pulsed laser deposition (PLD) technique to investigate the influence of the laser fluence on the structure, morphology and photoluminescent properties of the films. The atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray Diffraction (XRD), energy dispersive x-ray spectroscopy (EDS), photoluminescence (PL) spectroscopy and the x-ray photoelectron spectroscopy (XPS) were used to characterize the films. The SrAl2O4:Eu2+, Dy3+ thin films gave two green PL emissions peaks coming from Eu2+ ions occupying the two Sr2+ sites in the SrAl2O4 host lattice. The green emissions were attributed to 4f65d1 ? 4f7 transitions of Eu2+. The films with well-defined grains gave superior PL intensity and long afterglow characteristics. The EDS and XPS results showed that the films consisted of all the major elements (i.e. Sr, Al and O) present in SrAl2O4:Eu2+, Dy3+ material. The carbon (C) and the Si peak from the substrate were also identified. The XPS depth profile results showed a linear relationship of the film thickness with the laser fluence. The variations of surface morphological and topographical properties of the films with the laser fluencies are discussed.

Analysis and Rectification of Factors Contributing Delays in Construction of Power Projects[ ]


This paper aims at identifying various factors of delays during the capacity planning and the execution phase of BoP by using suitable delay analysis techniques. Delay analysis is the technique used to identify causes of delay and the impact they have on the progress and completion of a project. It is necessary in some form for claims for extensions of time and cost of prolongation. Without it a contractor will fail to demonstrate any entitlement.It is crucial to any claim that the most appropriate method of delay analysis is adopted. If we choose a method that fails to deal with issues such as culpable delays, concurrent delays and changes in logic then the claim might be easily rebutted. Whereas, using a sophisticated method for a simple issue can be a waste of time and money. A number of factors influence the selection of approach including the requirements of the contract, quality of the contractor’s planned programme, quality and extent of records and the complexity of the issue.

Segmentation of Tooth and Pulp from Dental Radiographs[ ]


Teeth and pulp segmentation for periapical radiographs is one of the most critical tasks for effective segmentation in periapical radiographs, and the process is difficult due to noise, low contrast, and uneven illumination of the dental radiographs. For accurate segmentation, images must be preprocessed either by image enhancement or image transformation or both so that the aforementioned problems will be reduced as much as possible. In this work, proposed an effective scheme to segment each tooth and pulp in periapical radiographs. The method consists of four stages: image enhancement using Contrast Limited Adequate Histogram Equalization(CLAHE), local singularity analysis using Hölder exponent, connected component analysis, and tooth segmentation using Chan-Vese segmentation.

Environmental and Performance Impact of Jatropha Biodiesel Blends on Combustion in Compression Ignition Engine[ ]


In this study, extracted oil from jatropha seeds was used to produce neat (pure) biodiesel through transesterification, and this converted biodiesel was used to prepare biodiesel/diesel blends. This study presents the preliminary research results of an investigation carried out on the potentiality of different biodiesel blends as an alternative fuel for compression ignition engines at load and no load conditions. The main objective of this research is to compare selected emissions of petroleum diesel with jatropha biodiesel fuel blends (B10, B20, B30, and B100) and B10* treated by ozonation. B20 produced the lowest CO concentration for engine test. B50 produced higher CO2 than other fuels for all engine tests, where B20 gave the highest. The biodiesel and biodiesel/diesel blend fuels produced higher NOx for various engine tests as expected. SO2 formation showed an increasing trend as the percentage of diesel increased in the fuels. Overall, we may conclude that B20 is the optimum fuel blends.

Hydrogeologic Conditions of Crystalline Basement Aquifers in Kauru Area of Kaduna, Nigeria[ ]


The paper assessed the hydrogeologic conditions of the crystalline basement rocks underlying the Kauru Area of Kaduna using data obtained from 26 producing wells in the area. Certain hydrogeologic characteristics of the aquifer which affect well productivity were investigated and analyzed. The minimum, maximum and the averages of the range of values of the hydrogeologic parameters were presented. The water table contour map of the area was prepared from the static water level data, and it shows that water table is generally deeper around the northwest-southeast axis of the middle section of the study area than at the southwest and northeast flanks of the LGA boundary. Graphical representation of screen lengths and specific capacities revealed that screen length has a direct effect on the specific capacity. Regolith thickness and saturated thickness showed a near-parallel variation from one well location to the other. The Pearson Product Moment Correlation analysis showed a strong positive correlation value of 0.746 between yield and drawdown, a weak correlation value of 0.48 between pumping rate and drawdown, and a very weak correlation value of 0.071 between yield and regolith thickness in the study area. The Regression Analysis, on the other hand showed that while drawdown rate has very strong and fairly strong linear relationships with yield and pumping rate respectively, yield has a very weak linear dependence on regolith thickness.

EXPERIMENTAL INVESTIGATION ON PRESSURE DROP CHARACTERISTICS OF BI-MODAL SLURRY FLOW IN A STRAIGHT HORIZONTAL PIPE[ ]


In the present experimental investigation, the pressure drop measurements are done over a length of 4.0 m in 50 mm NB diameter pipe line under fully developed flow conditions using a pilot plant test loop for narrow sized silica sand slurry and bi-modal slurry. The bi-modal slurry consists of narrow sized silica sand and fly ash as fine particles in different proportions keeping the overall efflux concentration. The deposition velocity characteristics of the abovementioned slurries are also measured experimentally. For bi-model slurry, at an efflux concentration of 20.4% (by weight), the pressure drop reduces considerably with addition of the fine particles and the reduction in pressure drop is more at lower velocities. Further, at efflux concentration of 33.9% (by weight), the pressure drop reduces at higher rate for low velocity region as compared to high velocity region with addition of the fine particles. The bi-model slurry shows slight reduction in deposition velocity with increase in percentage of fines for both efflux concentrations.

A GIS Model for Site Selection of Industrial Zones in Sri Lanka[ ]


Site selection of industrial zones in Sri Lanka has become a critical issue and a sensitive decision making process that may create a range of socioeconomic and environmental problems over time. Hence, several site selection criteria and appropriate methods for establishing industries have to be concerned by the decision makers and authorities before locating industrial zones in particular regions. Though, at present the enormous data volume and complex criteria regarding this field are available, the suitable site selection process is still problematic. Therefore, this paper assumes that, in some extent, such failures can be overcome by applying Geographic Information System (GIS) and Multi-criteria Decision Making Techniques into the site selection process of industrial zones.

Decreasing Musculoskeletal Complaints by Developing Product Design based on Ergonomics Participatory[ ]


The farming tools are vary, but nevertheless there are still some design of farming and building tools only consider the function but do not consider the wants and needs of users. Farmer are given product that are ready to use produced by large industry while construction workers only hammering the nail using ready to use hammer every day. Some tools only consider the function and have not adjusted to anthropometry of hands so that there are potential of force postures in operating, handle is not comfortable, early Complaints frequently happen when operating tools which is signed by spontan rest. Using of tools which does not consider the wants of users will effect to increase of postural stress of workers. Therefore design that considering the wants and needs of users by using participatory ergonomic approach is needed. This research is an experimental research using the post test only control group design because population of farmer considered homogen. Subjects totaled 46 are chosen randomly. Musculoskeletal complaints are measured by questionnaire Nordic Body Map (NBM). Result of questionnaire are compared and analyzed. Result shows that there is meaningful decrease between average score of musculoskeletal complaints when using conventional sickle with new design of sickle, but in use of hammer, there is no meaningful decrease because the change is only 3.681%. Redesign of tools based on user need could decrease musculoskeletal complaint as 15.517%

A Study on the Major Causes of Labour Unrest and Its Effect on the RMG Sector of Bangladesh[ ]


Labour unrest is one of the important issues in RMG sector of Bangladesh. Letting this issue unsolved could lead Bangladesh RMG sector to a place, where other competing countries become a threat in the international market of RMG. To find out the causes behind labour unrest, data collection has been carried out by questionnaire and interview methods. 20 workers & 20 staff from different garment factory of Dhaka, Savar, Gazipur and Narayanganj have been brought under the questionnaire method. The major causes of labor unrest or turbulence have been explored from the responses of the respondents. These are- irregularities in payment, low wage, mistreatment of the workers by managers/ officers, rumor, absence of trade union, conspiracy, non-execution of labor laws, unruly nature of the workers and political intervention. In key issues regarding labor unrest such as investigating the incidents of labor unrest, bridging the gap between the factory owners and workers, improving law and order situation, majority of the respondents want the involvement of ‘tripartite committee’ (a committee formed by the representatives of Government, factory owners and workers) which indicates a bright prospect of public-private cooperation in addressing labor unrest in the RMG sector of Bangladesh. If private sectors with their first-hand knowledge and experience cooperate with public agencies having power and authority, labor unrest in the RMG sector of Bangladesh is supposed to be solved.

Face Recognition and Retrieval Using Association Rules in Android Operating System[ ]


The task of face recognition has been actively researched in recent years. The goal of this paper is to implement face detection and face recognition system on the Android Operating System for use on mobile devices. After difficulties were experienced while attempting to inte-grate the two Components, a Visual Basic implementation was accomplished instead. In this paper, we present face detection algorithm was successfully implemented on Android Operating System version (4.3) which involved programming in Java language version 6 and face recognition system successfully implemented in programming language visual basic 6.0. The main idea of the proposed system depends on the fact that any face image person has multi unique features. These features are different from one face image to another. Our proposed algorithm depends on moment invariants to extract features from the face image person to extract association rules between these features to recognition face images person and retrieval. And then each face image is sored with its association rules in the association rules database to be used in face image recognition and retrieval systems. Where using canny edge detection in moment invariant. In this paper the features vector that represent the face features consists of seven features. The proposed system tested on dataset consists of 300 images for 30 persons for each person 15 images in different lighting conditions, varied in expression, orientations, illumination, skin color, background, ages, and faces shapes (the mouth and eyes are open or closed, with or without glasses, male and female... etc.). The achieved training rate was 100% and recognition rate 84.3% and the average of precision 82%.
