      • Abstract: The target of this project depends on IT administration arrangement of Sonali Bank Limited (SBL). The framework makes the administration procedure speedier and solid which will be especially steady for the association. It likewise gives distinctive sorts of reports of various classes that help the higher administration in taking choice. For outlining reason, Entity relationship graph and Data word reference are utilized. In our temporary position report, we have attempted to concentrate on utilizing programming for Lunch administration framework for smooth administration of extra parts. Hence, we have exclusively worked for lunch administration framework in Sonali Bank IT Dept. Our proposed programming will have the capacity to demonstrate the present status of while taking a lunch administration. The framework will diminish some of manual strides between request passages to item conveyance prepare. That is the reason; the item circulation framework will be quicker contrast with existing procedure. The all division can be effectively gotten lunch appropriation; office give could make vital strides. In general, the framework will guarantee speedier conveyance to the client. To finish our project we have utilized Oracle in backend and Oracle shape developer as front end stage. In addition, we have built up the report utilizing Oracle reports R6i.This programming is finished trailed by some strategy; these are Preliminary Investigation, System Analysis, System Design, Programming, Coding, Testing and Conversion..

      • Abstract: Obstacle detection is an active research area in the field of image processing. On road obstacle detection is an important problem in the area of intelligent transportation systems, driver assistance systems and automated guided vehicles. The proposed algorithm detects all obstacles on road using a single onboard camera which is mounted on a travelled vehicle in real-time for driver assistance. When the obstacle found in front of travelled vehicle using morphological filtering then the driver assistance system gives warning to the driver for avoiding collision. Experimental results are given for real time on road obstacle detection..

      • Abstract: Present paper deals with the assessment of water quality of Mithi River, Mumbai. The river was studied over a period of one year. Six different sites with ecological importance and and geographical variation sites were identified and selected for evaluation of its physico - chemical nature. The results obtained from different parameters studied were pH (6.12-7.84), Sodium (2.4mg/l - 68mg/l), Potassium (8.72mg/l - 746mg/l), Magnesium (135mg/l - 2808mg/l), Total Phosphorous (0.039 mg/l - 2.10 mg/l), Total Kjeldahl Nitrogen (0.8 mg/l - 3.35 mg/l) and Chloride (1.26 mg/l – 3.9 mg/l). Each of which less or greater in quantity, contributes to the ecosystem significantly. Majority of the parameters exhibited higher levels at sampling stations 2, 3 and 4 indicating pollution load due to domestic sewage discharge and addition of effluents from nearby industries..

      • Abstract: A fluid flowing over an object has a tendency to drag the object along its flow direction. An object passing through a fluid which is stationary there is a tendency to slow the object down. For a stationary object in a fluid which is flowing there is a tendency to move the object in the fluid flowing direction .These tendencies of flowing fluid is known as drag. While moving through air airplanes also subjected to several drags. Airplanes subjected to pressure drag or form drag due to flow separation which is based on the pressure difference between the upstream and downstream surfaces of the object. Airplanes also subjected to Skin friction drag which results from the viscous shear of the fluid flowing over the object surface. In order to overcome these drags airplane wings cross section airfoils are designed very carefully. National Advisory Committee for Aeronautics, or NACA, developed and tested "families" of airfoils. Some of the most successful of these were the NACA four-digit and five-digit series. The necessary coordinates for designing NACA airfoil profiles are available in online. UIUC also provide coordinates for designing NACA airfoil profiles. But the present work describes the way of designing NACA four digit airfoils without taking any coordinates from available sources like google or any other search engines. Using C programming with the help of NACA provided equations a generalized source code is designed .Which will provide coordinates for designing any NACA four digit airfoil profiles .With the help of this obtained profile the wing model is also constructed using solid works. Using solid works model the real model was constructed using wood. The chord of regular surface airfoil is 21 cm and the span is also 21 cm. The airfoil profile taken for the model construction is NACA-4415 which is a four digit cambered airfoil.The present work also show some figures of an airfoil by applying certain surface modifications in form of dimples..

    Investigation of some geotechnical properties of the tropical soil in Abia state, Nigeria

      • Abstract: Knowledge of the basic soil properties is inevitable in effective foundation designs for the stability and sustainability of the sub-structures. Any compromise in this direction normally leads to waste of resources or structural failures in the foundation. The risk is high in depositional formations that are characterized with significant settlement in foundation. Since the tropical soil in Nigeria is of depositional formation, the study therefore investigates the geotechnical properties of the tropical soil in Abia state to form a data base for effective design of foundations in the area. Laboratory tests were therefore conducted on sets of soil samples collected from various locations in the state. The soil tests were centered on the index properties of the soil which include; Gradation, Atterberg Limits, Moisture Content, Specific Gravity and Compaction tests. With the test results of the index properties of the soil, appropriate models which link index properties to strength properties in the area were used to calculate the values of California Bearing Ratio (CBR) and Unconfined Compressive Strength (UCS) of the soil. The analyses show that the tropical soil is composed of Coarse Grained soil of predominantly Silty Sand (SM). Although about 80% of the soil grain is retained in the 0.002mm sieve; it falls short of group A-4 in AASHTO soil classification but, belongs to group A-5 soil classification. Findings from the compaction tests show that moisture content of the soil at 5% is considerably lesser than the optimum water content at 11%. Considering this and the plastic index of 8, the soil is considered plastic in nature and stable for foundation works. Because the CBR and UCS are at 2.83kn and 21kn/m2 respectively, the CBR is low but considered not good enough to be used for base construction on roads except for sub-base constructions since; the average value is not up to 80% measure of the standard CBR value..

      • Abstract: Micro strip antennas suffer from narrow bandwidth. The dimension of the microstrip feed line and ground plane can play important role in proper impedance matching. A good matching results an enhancement of the bandwidth. This paper demonstrates the bandwidth enhancement of a square micro strip antenna in by using feed line shape and ground plane. Conventional microstructure antennas have larger ground plane. The effect of the ground plane is to confine the waves and hence increases the directivity of the Antenna. The dimensions of the ground plane and feeding technique have a direct effect on the variations of the input impedance and resonant frequency. The effect of feed dimension and ground plane on the return loss and bandwidth is observed and presented in the paper. By changing shape of the feeding line and ground plane a 575 MHz bandwidth is obtained with maximum return loss at -29d B. The simulations are conducted using FHSS, and results of the simulation are presented in the paper..
