Secure Model to Generate Path Map for Vehicles in Unusual Road Incidents Using Association Rule Based Mining in VANET

引用

Journal of Electronic Science and Technology 2018年第2期16卷 153-162页

作者： arun malik Babita Pandey Chia-Chun Wu Department of Industrial Engineering and Management National Quemoy UniversityQuemoy 89250

Logical behavioral arrangements are a class of conventional arrangements to illustrate the happening of incidents in an appropriate and structured approach in vehicular ad hoc network （VANET）. These incidents are characterized as a list of path segments that are passed through by the vehicles for the duration of their journeys from a pre-decided local source to a local destination in a structured manner. A set of proper description illustrating the paths traversed by the vehicles as logical behavioral arrangements is describedin this paper. The data gathering scheme based on secure authentication to gather the data from the vehicles is proposed in this paper. This proposed data gathering scheme based on secure authentication is compared with the existing data gathering schemes by using veins framework and the results of analysis reflect that the proposed scheme outperforms among others. The data collected from the vehicles by the proposed data gathering scheme is stored at distributed road side units （RSUs）. From these collected paths, the common and frequent paths opted by the vehicles in a certain region are determined by using frequent arrangement mining approach. An estimation model is used to decidethe next path and the whole path map opted by the vehicles in unusual situations like accident, jams, or a particular time of day. The proposed scheme will helpthe society in reducing the waiting time in vent of emergency or normal working days.

Correlation of Electric Cardiometry and Continuous Thermodilution Cardiac Output Monitoring Systems

引用

World Journal of Cardiovascular Surgery 2014年第7期4卷 101-108页

作者： Vishwas malik arun Subramanian Sandeep Chauhan Milind Hote Department of Cardiac Anesthesiology All India Institute of Medical Sciences New Delhi India Department of Cardiothoracic and Vascular Surgery All India Institute of Medical Sciences New Delhi India

Purpose: Impedance Cardiography (ICG) with its drawbacks to reliably estimate cardiac output (CO) when compared to reference methods has led to the development of a novel technique called Electrical Cardiometry (EC). The purpose of this study was to compare EC-CO with the Continuous CO (CCO) derived from Pulmonary Artery Catheter (PAC). Methods: 60 patients scheduled to undergo coronary artery surgery necessitating the placement of PAC were studied in the operating room. Standard ECG electrodes were used for EC-CO measurements. Simultaneous CO measurement from EC and PAC was done at three predefined time points and were correlated. Results: A significant high correlation was found between the EC-CO and CCO at the three time points. Bland and Altman analysis revealed a bias of 0.08 L/min, a precision of 0.15 L/min, with a narrow limit of agreement (-0.13 to 0.28 L/min). The percentage error between the methods was 3.59%. Conclusion: The agreement between EC-CO and CCO is clinically acceptable and these two techniques can be used interchangeably. Mediastinal opening has no effect on the correlation between these two modalities.

Intensity Dependent Nonlinear Absorption in Direct and Indirect Band Gap Crystals under Nano and Picosecond Z-Scan

引用

Optics and Photonics Journal 2012年第2期2卷 98-104页

作者： Dimple Sharma Poonam Gaur Bharam Pal malik Nageshwar Singh arun Gaur Department of Physics Deenbandhu Chhotu Ram University of Science and Technology (D.C.R.U.S.T) Murthal Sonipat India Department of Physics Hindu P.G. College Sonipat India Laser Systems Engineering Division (L.S.E.D.) Raja Rammanna Centre for Advanced Technology (CAT) Indore India

The nonlinear absorption properties of direct (GaN) and indirect (CdI2) band gap crystals have been studied by using an open aperture Z-scan technique under fundamental (1064 nm) and frequency doubled (532 nm) wavelength respectively with 10 ns or 60 ps pulse durations. Direct band gap crystal exhibits two and three photon absorption at all input irradiances. On the other hand, at low input irradiance the indirect band gap crystal exhibits saturable absorption (SA). At higher input irradiances two and three photon absorption becomes dominant. A monotonic increase of the nonlinear absorption coefficients with increasing laser pulse duration from 60 ps to 10 ns is observed for GaN and CdI2 crystals.

Revised national tuberculosis control programme in India has limited co-hort-wise information about what happens to patients diagnosed with multidrug resistant TB (MDR-TB). We determined the pre-treatment loss to follow-up (non-initiation of treatment by programme within 6 months of diagnosis) and time from diagnosis to treatment initiation in Bhopal district, central India (2014). Pre-treatment loss to follow-up was 13% (0.95 CI: 7%, 23%), not significantly different from the national estimates (18%) and median time to initiate treatment was seven days, lower than that reported elsewhere in the country. Bhopal was performing well with reference to time to treatment initiation in programmatic settings.
