ZigBee Based Home Security Alert System: An Integrated Approach
C.P. Jeba Samuel,S. Prakash,M. Ananda Kumar,D. Manivannan
Journal of Artificial Intelligence , 2013,
Abstract: In remote home monitoring security system, embedded devices play a vital role. In this study, GSM, ARM and ZigBee are used to establish a security for smart home. In this study, LPC2148 is used as Microcontroller Unit (MCU), Resistance Temperature Detectors (RTD) to observe temperature, smoke sensor to detect the presence of smoke and vibration sensor over doors and windows to detect forced entry, overall system safeguard the home from burglary. On entering the correct password, MCU disarms the security feature else it activates the alarms and sends image of the burglar to amenable persons through ZigBee and whenever there is smoke or fire MCU sends SMS to owner as well it automatically activates safety measures like, opening window turns on the exhaust fan and sprinkler.
LRS Bianchi type -V cosmology with heat flow in scalar: tensor theory
Singh, C.P.;
Brazilian Journal of Physics , 2009, DOI: 10.1590/S0103-97332009000600002
Abstract: in this paper we present a spatially homogeneous locally rotationally symmetric (lrs) bianchi type -v perfect fluid model with heat conduction in scalar tensor theory proposed by saez and ballester. the field equations are solved with and without heat conduction by using a law of variation for the mean hubble parameter, which is related to the average scale factor of metric and yields a constant value for the deceleration parameter. the law of variation for the mean hubble parameter generates two types of cosmologies one is of power -law form and second the exponential form. using these two forms singular and non -singular solutions are obtained with and without heat conduction. we observe that a constant value of the deceleration parameter is reasonable a description of the different phases of the universe. we arrive to the conclusion that the universe decelerates for positive value of deceleration parameter where as it accelerates for negative one. the physical constraints on the solutions of the field equations, and, in particular, the thermodynamical laws and energy conditions that govern such solutions are discussed in some detail.the behavior of the observationally important parameters like expansion scalar, anisotropy parameter and shear scalar is considered in detail.
Rethinking regulation: international banks in Asian emerging markets
C.P. Chandrasekhar
PSL Quarterly Review , 2011,
Abstract: Financial systems in Asian emerging market economies are seen as resilient because of their performance during and after the 2008 crisis. But such assessments focus on the current status rather than the direction of evolution of those systems, many of which are being substantially liberalised. One consequence is the growing presence of foreign banks in these markets, invited on the grounds that they would enhance competition and induce domestic banking systems to adopt better technologies and practices. By contrast, it is here maintained that what they are likely to do is alter banking behaviour in ways that are inimical to growth and inclusion and increase instability.

Predictive model on the effect of restrictor on transfer function parameters on pneumatic control system
Ukpaka, C.P
Chemistry Internatioanl , 2016,
Abstract: Mathematical model was developed to monitor and predict the influence of restrictor or the characteristics of the functional parameters of the transfer function for pneumatic control system. The force acting from bellow is directly proportional to the effective cross-sectional area of the base which yielded extension of the bellow in both horizontal and vertical as well as its extension rate is dependent on the influence of the restrictor. The pneumatic controller represents the main force control operator in many industrial applications, where it’s static and dynamic characteristics play an important role in the overall behavior of the control system, the total differential expression obtained in terms of restrictor pressure change per unit change in time was presented. The general solution equation established was resolved using the mathematical concept of laplace transformation as well as application of partial fraction which yields PR(t) = . The effect of the restrictor on the characteristics of the pressure was monitored, predicted and simulated using the MATLAB program approach. Result obtained reveals increase in restrictor pressure with increase in time. Restrictor pressure is influence by the capacitance, input pressure of bellow characteristics as well as other functional parameters.

International Journal of Electronic Business Management , 2010,
Abstract: In this study, we develop a collaborative inventory system consisting of one supplier and one buyer. The objective is to maximize the total profit of the whole system when shortage caused by the imperfect quality can be completely backordered. To ensure mutual benefits to every player, a negotiation mechanism is incorporated to share the profit between both players according to their contribution. A deteriorating inventory system with finite replenishment rate and price sensitive demand is set to simulate a real situation of the high-tech, short life cycle and perishable fashion product. A numerical example and sensitivity analysis are carried out to illustrate the model.
Statistical Modeling of Breast Cancer Relapse Time with Different Treatments
C. Cong,C.P. Tsokos
Journal of Applied Sciences , 2010,
Abstract: In the present study, we extended the work that was published in performing statistical modeling on the breast cancer data containing patients in two different treatments, namely radiation plus tamoxifen and tamoxifen alone and compared the results and identified the attributable variables along with interactions that relates to reoccurrence of breast cancer based on the consistent results obtained from accelerated failure time model and cox proportional hazard model where interactions of attribute variables are introduced. Cox proportional hazard model is also chosen over accelerated failure time model to calculate the appropriate survival curves of relapse time for patients in different treatment groups. In addition, we have developed and applied the cure rate model which gives a better insight on the cure rate of the two breast cancer treatments from a different perspective.
Information and communication technologies and health in low income countries: the potential and the constraints
Chandrasekhar,C.P.; Ghosh,J.;
Bulletin of the World Health Organization , 2001, DOI: 10.1590/S0042-96862001000900010
Abstract: this paper outlines the potential offered by technological progress in the information and communication technologies (icts) industries for the health sector in developing countries, presents some examples of positive experiences in india, and considers the difficulties in achieving this potential. the development of icts can bring about improvements in health in developing countries in at least three ways: as an instrument for continuing education they enable health workers to be informed of and trained in advances in knowledge; they can improve the delivery of health and disaster management services to poor and remote locations; and they can increase the transparency and efficiency of governance, which should, in turn, improve the availability and delivery of publicly provided health services. these potential benefits of icts do not necessarily require all the final beneficiaries to be reached directly, thus the cost of a given quantum of effect is reduced. some current experiments in india, such as the use of personal digital assistants by rural health workers in rajasthan, the disaster management project in maharashtra and the computerized village offices in andhra pradesh and pondicherry, suggest creative ways of using icts to improve the health conditions of local people. however, the basic difficulties encountered in using icts for such purposes are: an inadequate physical infrastructure; insufficient access by the majority of the population to the hardware; and a lack of the requisite skills for using them. we highlight the substantial cost involved in providing wider access, and the problem of resource allocation in poor countries where basic infrastructure for health and education is still lacking. educating health professionals in the possible uses of icts, and providing them with access and "connectivity", would in turn spread the benefits to a much wider set of final beneficiaries and might help reduce the digital divide.
A Combination of Genetic Algorithm and ART Neural Network for Breast Cancer Diagnosis
C.P. Sumathi Punitha,T. Santhanam
Asian Journal of Information Technology , 2012,
Abstract: Medical diagnosis is one of the major problems in medical application. This includes the limitation of human expertise to diagnose disease manually. Extensive amount of knowledge and data stored in medical databases require specialized tools for analysis and effective usage of data. Breast cancer is one of the most common types of cancer in women in many countries. An intelligent tool, which will help in diagnosing the breast cancer, is the need of the hour. Researchers have found that Neural Network (NN) capabilities can help them to improve this domain and the use of Genetic Algorithms (GA) to optimize the input space. As many researchers have discovered, NNs and GAs may be combined which will result in highly successful adaptive systems. The performance of genetic algorithms and Adaptive Resonance Theory (ART) neural network for increasing the accuracy and objectivity of breast cancer diagnosis using the well-known and widely accepted Wisconsin Breast Cancer Data (WBCD) is examined in this study.
