PC Based Low Cost Energy Meter Billing System for Home and Commercial Buildings[ ]


Meter reading is an important part of billing system for residential and commercial buildings. The importance of an effective and efficient billing system cannot be over emphasized. This is very critical as small errors can lead to substantial loss of revenue. This often does not reflect the exact or true electricity consumption of such buildings, resulting in an inefficient bill mainly due to human errors. Thus, it is essential to have an efficient and effective system for this measurement purposes. This paper is about the design and construction of a personal computer (PC) based power monitoring system. It is made up of integrated circuits, active and passive hardware devices and a Visual Basic software program which is used for programming the PC serial port. This design monitors the amount of electrical power used, up to 600 watt, transmitting data through a central receiving unit connected to a PC via USB serial (COM) port. The PC displays and stores the data for future recall and simple cost analysis. The device is used to measure accurately the electric power consumed by a residential or commercial buildings which is more economical compared to the electromechanical devices. Utility companies can directly monitor and control electrical power supply billing of its distributed consumers without engaging the services of human oriented meter readers. The meter displays the consumed power per minute. The potential of the developed system are mainly the advantages of virtual instrumentation, flexibility, lower built cost and high performance, high accuracy in power monitoring and power management.

Protective effect of black tea extract during chemotherapeutic drug induced oxidative damage on normal lymphocytes in comparison with cancerous K562 cells[ ]


Daunomycin and adriamycin have been widely used as chemotherapeutic drugs against varied number of cancers, however, non-targeted cytotoxicity has been limiting their therapeutic ratios. In the present study, protective effect of black tea, rich in natural antioxidants has been investigated against drug induced oxidative damage in normal lymphocytes and compared with erythroleukemic K562 cells. Pre-treatment with black tea extract (BTE) significantly reduced loss of cell viability, generation of ROS, mitochondrial dysfunction, DNA damage, activation of caspase-3 and apoptosis in normal lymphocytes compared to K562 cells. HPLC analysis confirms that extracellular BTE penetrate the cell membrane in both types of cells and also regulate the activity of endogenous antioxidant enzymes. The changes in the mRNA expression of bax, bcl2, p53 and Nrf2 were also followed to evaluate regulation of drug induced apoptosis by BTE. The findings demonstrate that black tea is a promising chemo-protective agent which can be supplemented along with chemotherapeutic drugs to reduce oxidative damage to non-targeted cells.

Mathematical Modeling and Simulation of Photovoltaic Solar Module in Matlab-Mathworks environment[ ]


This paper presents a mathematical modeling and simulation of a photovoltaic solar module. Mainly an accurate mathematical model for computing Maximum Power output of a photovoltaic PV module is presented. The model for PV panel is developed based on the single-diode photovoltaic model, found in the literature, including the effect of the series resistance. A typical 60 W photovoltaic panel is selected for simulation in Matlab-Mathworks environment. The essential parameters, required for modeling the photovoltaic module, are taken from datasheets provided from manufactures’. Current-Voltage and Power-Voltage characteristics are obtained, for the selected module, from simulation and compared with the experimental curves. On the other hand, this model is used to compute and to investigate the variation of Maximum Power output of a PV module with temperature and irradiance intensity levels. A validation of the proposed mathematical model is performed by an interactive analysis and comparison between simulation results and the typical PV module datasheet. The simulation results are well matched with the experimental data.

A Review: Image Segmentation Using Genetic Algorithm[ ]


Image segmentation is an important and difficult task of image processing and the consequent tasks including object detection, feature extraction, object recognition and categorization depend on the quality of segmentation process. In this paper we suggest Genetic Algorithm to solve the problem of image segmentation. The problem was treated as optimization problems based GA. GAs is used to segment an image by using an optimization function without any threshold values. GAs based image segmentation can provide more accurate results than traditional segmentation methods. The genetic procedure provided a faster convergence to the optimal solution. This is because the sampling strategy allows exploring the solution space by a strategy that is not biased. The preliminary results indicate that GA-based methods perform better than the traditional methods in terms of quality. Also, by developing hybrid algorithms such as GAs and Artificial Neural Networks (ANNs) we can reduce the processing time and increase the visual quality of the final segmentation underscoring the advantages of hybrid algorithms.

The present work deals with the development of an artificial olfactory system as a nondestructive instrument to be used for classification of different fruits and exploration of its application in measurement of fruit ripening stages. The fruits chosen for this study are Guava, Orange and Banana. The developed system comprises of an array of eight metal oxide semiconductor gas sensors, odor delivery system, interface circuit board, data acquisition card and self programmed Data acquisition as well as analysis software using LabVIEW. The design of this tool focused on studying the response of a sensor array to various VOC vapors released by fruit during ripening and optimizing the data acquisition, signal preprocessing, storage, feature extraction parameters using principle component analysis. It was found that developed e-nose can discriminate the patterns of volatile organic compounds (VOCs) from three fruits taken for experimentation. These three fruits, as analysed by the principal component analysis (PCA). With further validation and development, this e-nose may become very useful for monitoring the exhaled as a screening device for discriminating the fruits. This e-nose can also be used for classification and grading of different climacteric fruits on the basis of their ripening stages.

EFFECT OF DEVIATIONAL CURING ON THE STRENGTH PROPERTIES OF CONCRETE[ ]


Concrete failures at site are associated to several reasons; right from concrete mix design, properties of materials used, mixing, placing, compaction, curing procedures and many more. There are many misconceptions about the duration of curing of concrete, especially when we refer to site conditions. Improper curing is considered as one of the significant reasons for concrete failures in columns, beams, slabs, pavements, etc, evident in the form of cracks, which are easily noticeable by the naked eyes. Unfortunately, curing is not given much importance on most of the sites which leads to reduction in the durability of the structure.

Special Relativity Contradicted by Oscillation[ ]


This paper deals with breakdown of Lorentz tansformations before oscillatory sequence of events. Lorentz tansformations are the basis of Einstein's special realtivity.Till to date none has found any pitfall in the theory. Any contradiction pointed towards the theory either ended in an apparent paradox or ended in a misunderstanding of the proposer himself. But the author here shows how the Lorentz transformations wrongfully transform even the simplest oscillatory motion rendering two sides of the transformed equation not equal. Therefore the author proposes this conjecture for settling the dispute and invoke new thinking. Einstein's theory although is the theory of clock synchronisation but is helpless before any kind of oscillation. In reality without oscillatory sequence of events we never can construct a clock and Lorentz transformation is expected to support this; but it is unfortunate that the matter turned really grave when Lorentz transformations want to transform an oscillation from one inertial frame to another. Perhaps Lorentz transformations are not final statement of transformation of event from one inertial frame to another.
