Automatic Bus Recognition Through Mobile
S.Nagendram, Y.Harikrishna
International Journal of Computer Trends and Technology , 2012,
Abstract: This paper presents a GPS (global positioning system) to track the vehicle in the remote areas. Here based on the latitude and longitude values of the vehicles anywhere on the globe, a microcontroller which will process the information and switch the GSM (global system for mobile communication) to send SMS to the users about present location, time, date, speed of the vehicle. In this method we give mobile number, bus number, line number, speed, date, to the controller center. Those who are subscribed to the controller centre it automatically sends the sms to the user through GSM modem. Here we create a program to the controller center to send an sms message to a User. Whenever it arrives near to the junction or crosses the junction it automatically update the further information regarding the location by using the GPS system and sends the SMS to the user by using the GSM modem. GSM modem and micro controller are combined for the purpose of automatic bus recognition with a smart phone. The method works in real time applications in terms of recognition rate and reliability.
SCARP: Secure Congestion Aware Routing Protocol for Wireless Sensor Networks
Ch.Radhika Rani,S.Nagendram,Subba Reddy Oota
International Journal on Computer Science and Engineering , 2011,
Abstract: Wireless sensor networks sense various kinds of information, process them locally and communicate it to the outside world via satellite or Internet. In the near future, sensor networks will play a major role in collecting and disseminating information from the fields where ordinary networks are unreachable for various environmental and strategical reasons. Hence it is increasingly likely that sensorswill be shared by multiple applications and gather heterogeneous data of different priorities. With such concentration on wireless sensor networks, vital issues like security and congestion control are to be taken care of. We propose Secure Congestion Aware Routing protocol (SCARP), a protocol designed for mitigating congestion by dedicating a portion of network to forward high-priority traffic primarily andalso satisfies the major security properties like data authentication, data secrecy, replay protection, freshness with low energy consumption which are the major factors affecting the wireless sensor networks.
ZIGBEE Based Voice Control System for Smart Home
Y. Bala Krishna,S. Nagendram
International Journal of Computer Technology and Applications , 2012,
Abstract: This paper details the overall design of a wireless home automation system (WHAS). This is fuelled by the need to provide supporting systems for the elderly and the disabled, especially those who live alone. The automation centre’s on recognition of voice commands and uses low-power RF ZigBee wireless communication modules which are relatively cheap. The home automation system is intended to control all lights and electrical appliances in a home or office using voice commands. The zigbee can receive the voice and send the voice data to the ARM9 controller and then the controller converts the voice into required format and then again send the data through the zigbee to the another zigbee and to the micro controller where the devices are attached to it. Based on the message it received it either turns ON/OFF the devices.
Efficient Resource Scheduling in Data Centers using MRIS
S. NAGENDRAM,J.VIJAYA LAKSHMI,D.VENKATA NARASIMHA RAO,CH.NAGA JYOTHI
Indian Journal of Computer Science and Engineering , 2011,
Abstract: Scheduling the resources is decisive in shared data centers. Today scheduling algorithms focus only on onedimensional resource models, infact the multiple resources (e.g. Memory, Storage, CPU and Networkbandwidth) can be consumed concurrently. There is a lot of demand for multiple resources in cloud computing which allows various users to share a data center. This paper depicts resource scheduling problemto a bounded multi-dimensional knapsack problem, taking into account the requirement dependency among multi-dimensional resources. Due to the NP hardness of B-MDKP, we present Multi-dimensional ResourceIntegrated Scheduling (MRIS), an inquisitive algorithm to obtain the approximate optimal solution. MRIS will be highly efficient and achieves high performance for a various set of workloads.
Study of the Structural and Electrical Properties of Cr-Doped BiFeO3 Ceramic  [PDF]
S. S. Arafat, S. Ibrahim
Materials Sciences and Applications (MSA) , 2017, DOI: 10.4236/msa.2017.810051
Abstract: Multiferroic BiFe1-xCrxO3 (x = 0.2 and 0.4) ceramics were synthesized in a single phase. The effects of Cr3+ substitution on the crystal structure, dielectric permittivity and leakage current were investigated. Preliminary X-ray structural studies revealed that the samples had a rhombohedral perovskite crystal structure. The dielectric constant ε' significantly increased while the dielectric loss tanδ was substantially decreased with the increase in Cr3+ substitution. The temperature effect on the dielectric properties exhibited an anomaly corresponding to magneto-electric coupling in the samples and was shifted to lower temperatures with the increase in Cr3+ substitution. The leakage current density also reduced in magnitude with the increase in the Cr3+ substitution.

S. S. Sandhya, S. Somasundaram, S. Anusa
Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.66086
Abstract: Let \"\" be an injective function. For a vertex labeling f, the induced edge labeling \"\" is defined by, \"\" or \"\"; then, the edge labels are distinct and are from \"\". Then f is called a root square mean labeling of G. In this paper, we prove root square mean labeling of some degree splitting graphs.
A Parameter Estimation Model of G-CSF: Mathematical Model of Cyclical Neutropenia  [PDF]
S. Balamuralitharan, S. Rajasekaran
American Journal of Computational Mathematics (AJCM) , 2012, DOI: 10.4236/ajcm.2012.21002
Abstract: We investigate the FFT (Fast Fourier Transform) model and G-CSF (granulocyte colony-stimulating factor) treatment of CN (Cyclical Neutropenia). We collect grey collies and normal dog’s data from CN and analyze the G-CSF treatment. The model develops the dynamics of circulating blood cells before and after the G-CSF treatment. This is quite natural and useful for the collection of laboratory data for investigation. The proposed interventions are practical. This reduces the quantity of G-CSF required for potential maintenance. This model gives us good result in treatment. The changes would be practical and reduce the risk side as well as the cost of treatment in G-CSF.

Fuzzy Based Intelligent Monitoring of Critical Lines in the Restructured Power Market  [PDF]
S. Rajasekaran, S. Sathiyamoorthy
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.79191
Abstract: Restructured electric market environment allows the power wheeling transactions between the power producers and customers to meet the growing load demand. This will lead to the possible of congestion in the transmission lines. The possible contingencies of power components further worsen the scenario. This paper describes the methodology for the identification of critical transmission line by computing the real power and reactive power performance indices. It also demonstrates the importance of fuzzy logic technique used to rank the transmission lines according to the severity and demonstrated on IEEE-30 bus system.
Error Correction Circuit for Single-Event Hardening of Delay Locked Loops  [PDF]
S. Balaji, S. Ramasamy
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.79210
Abstract: In scaled CMOS processes, the single-event effects generate missing output pulses in Delay-Locked Loop (DLL). Due to its effective sequence detection of the missing pulses in the proposed Error Correction Circuit (ECC) and its portability to be applied to any DLL type, the ECC mitigates the impact of single-event effects and completes its operation with less design complexity without any concern about losing the information. The ECC has been implemented in 180 nm CMOS process and measured the accuracy of mitigation on simulations at LETs up to 100 MeV-cm2/mg. The robustness and portability of the mitigation technique are validated through the results obtained by implementing proposed ECC in XilinxArtix 7 FPGA.
