 Abstract

In this paper we present the patient specific system proposed for accurate and robust detection of ECG heartbeat pattern. In recent years many works have been proposed for ECG data classification. Detection of any disorder in heart rhythm or any change in morphological pattern which an indication of arrhythmia so finding that change for the treatment of heart patients at the early stage play an vital role . we required an effective diagnostic system as human eyes are poorly suited to detect the morphological variation of ECG signal also it is difficult for doctors to analyze long ECG records in the short period of time .In this proposed system feature extraction for the morphological feature, which are projected onto a lower dimensional feature space using Principal Component Analysis (PCA) and temporal feature from ECG data. Artificial neural network ANNs is used for pattern recognition. ANN is powerful tools for pattern recognition, as it having potential to learning complex and nonlinear surfaces. The ECG pattern classification performance strongly depends on the characterization power of the features extracted from the ECG data and the design of the classifier. Nonstationary ECG signal is effectively analyzed by the TI-DWT due to its time�frequency localization properties. PCA is well-known statistical method that has been used for data compression, data analysis, redundancy and dimensionality reduction, and feature extraction. PCA is the optimal linear transformation in which we ?nds a projection of the input pattern vectors onto a lower dimensional feature space that retains the maximum amount of energy among all possible linear transformations of the pattern space .The proposed classification system can adapt significant interpatient variation in ECG patterns by training the network structure, and thus we achieves higher accuracy over larger datasets.

Abstract Aim: The objective of the present study was to analyze the prevalence of various factors in knee pain patients and to identify the association of knee pain with balance and joint proprioception in knee pain patients. Method: This was a descriptive co-relational study design that was carried out from September 2018 to April 2019 with a convenient sample size of 75 patients having knee pain, aged between 30 and 65 years (both males and females). The patients were assessed for knee pain and disability by WOMAC questionnaire. For balance and joint Proprioception subjects were tested on the Y-Balance test and CPM (Continuous Passive Motion) machine. Result: The present study revealed that the prevalence of knee pain was higher in women who were housewife�s (47.4%). A significant inverse relationship was found between Balance and NPRS, Balance and WOMAC. A significant relationship was found between joint proprioception deviation and NPRS, joint proprioception deviation and WOMAC. Conclusion: In the present study gender, older age, and greater BMI were associated with knee pain and disability. Knowing specific risk factors of individuals with knee pain and possible association with each factor is important as it may help to develop specific treatment or management strategies.

Abstract - Bio-diesel has become one of the most versatile alternative fuel options for diesel engine applications. The recent bio-diesel researches in India receives its attention towards Jatropha curcas oil based bio-diesel. In India plants bearing seeds which are rich in oil has been found mainly Jatropha curas (Ratan jot) and Pongmia Pinnata (Karanja) which are grown in our suitable climatic conditions (Patil and Singh, 1991). The use of bio-diesel is economically feasible and a strategic option, to meet the increasing demand of energy requirement of the nation. Out of various non-edible oil resources, Jatropha curcas oil is considered as an alternate fuel for compression ignation engines. The present study describes the process used for blending of Jatropha oil with diesel. For finding mechanical parameters. A vertical water cooled diesel engine used under study for various measurements. Jatropha oil blended in the proportion of 20,40 and 60 percent (by volume) respectively in the diesel. The specific fuel consumptions at various loads has calculated under study. Respective performance analysis has evaluated. In has found that the minimum fuel consumption was found with B60 blend as 0.1966 Kg/KWh and maximum B.T.E of 43.67% obtained at 70% load conditions, shown as 32% increase as compare to diesel with full load operations. At the same time there were decrease of 3.3% and 1.6% in volumetric efficiency and mechanical efficiency respectively at full load operations with B60 blend of diesel oil.

 Abstract

Box culverts are very important part of a transportation network as they provide a cost-effective alternate to substantial bridges. A culvert is a structure that allows water to flow under a road ways, railways, or similar obstruction from one side to the other side. A culvert may be made from a pipe, reinforced concrete or other material. Culverts are commonly used both as cross drains for channel release and to pass water under a road at natural drainage and river crossings. A culvert may be a bridge like structure designed to allow vehicle or pedestrian traffic to cross over the watercourse while permitting suitable opening for the water. Culverts can be of different shapes such as arch, slab and box. These can be constructed with different material such as masonry (brick, stone etc.) or reinforced cement concrete. Since culvert pass through the earthen embankment, these are subjected to same traffic loads as the road carries and therefore, required to be designed for such loads. This Paper deals with box culverts made of RCC, without cushion. The size, invert level, layout etc. are decided by hydraulic considerations and site conditions. The scope of this Paper has been further restricted to the structural design of box. The structural design involves consideration of load cases (box empty, full, surcharge loads etc.) and factors like live load, effective width, braking force, dispersal of load through fill, impact factor, co-efficient of earth pressure etc. Relevant IRC Codes are required to be referred. The structural elements are required to be designed to withstand maximum bending moment and shear force. The Paper provides full discussions on the provisions in the Codes, considerations and justification of all the above aspects on design. Box Culverts are required to be provided under earth embankment for crossing of water course like streams, Nallas across the embankment as road embankment cannot be allowed to obstruct the natural water way. The culverts are also required to balance the flood water on both sides of earth embankment to reduce flood level on one side of road thereby decreasing the water head consequently reducing the flood menace. Culverts can be of different shapes such as arch, slab and box. These can be constructed with different material such as masonry (brick, stone etc) or reinforced cement concrete. Since culvert pass through the earthen embankment, these are subjected to same traffic loads as the road carries and therefore, required to be designed for such loads. The size, invert level, layout etc. are decided by hydraulic considerations and site conditions. The cushion depends on road profile at the culvert location. The structural design involves consideration of load cases (box empty, full, surcharge loads etc.) and factors like live load, effective width, braking force, dispersal of load through fill, impact factor, co-efficient of earth pressure etc. Relevant IRC Codes are required to be referred in the analysis and design of box culverts. The aim of this project is to analyse the box culvert using STAAD PRO software. The structural elements of box culvert are designed to withstand maximum bending moment and shear force. The results obtained from STAAD are almost similar to manual calculations.

 Abstract

Concrete is the mostly used construction material. However, Cement, an essential constituent of concrete, its production leads to release of significant amount of CO2, a greenhouse gas. For the production of one ton of Portland cement approximately one ton of CO2 with other greenhouse gases are created. The global cement industry emits about 7% of greenhouse gas to the atmosphere. As environmental issues are playing an important role towards sustainable development of cement and concrete industry so we need to replace cement by using waste material. One of the waste material is Glass. Tons of waste glass is being produced annually all over the world and this waste is disposed as landfills but as a matter of fact the waste of glass doesn�t decompose in the environment. On one hand Large scale production of cement is causing environmental problems and on other hand depletion of natural resource. In this paper cement is been partially replaced by milled waste glass that is waste glass powder with the increment of 5% from 0% to 30%. Test was taken for Workability, Compressive and Flexural strength for 7 and 28 days and compared with the result of conventional concrete. So by getting good test results it shows that cement could be partially replaced by milled waste glass.
