A simple spectrophotometric method is presented for the rapid determination of copper at a trace level using 2,5-dimercapto-1,3,4-thiadiazole (DMTD) as a new spectrophotometric reagent. The method is based on the reaction of non-absorbent DMTD in a slightly acidic (0.002-0.014 mol dm(-3) sulfuric acid) aqueous solution with copper(II) to produce a highly(More)
In this study, five compounds, lupeol (1), epilupeol (2), β-sitosterol (3), stigmasterol (4) and p-methoxybenzaldehyde (5) were isolated from the petroleum ether and dichloromethane fractions of a methanolic extract of the stem bark of Delonix regia. Antimicrobial screening of the different extracts (15 μg mm-2) was conducted by the disc diffusion method.(More)
Association of a true observer guaranties electronic cash not to be double-spent by any means. Java card is a smartcard which represents one of the smallest computing platforms. A major challenge influencing the design and implementation of e-cash observer in Java card is the limited availability of computing resources in it. In this paper, we show a new(More)
Telemedicine encompasses methods for electronically transmitting medical information to sustain and/or improve patient's health condition by using information and communication technology. Different countries of South Asia have tried to introduce telemedicine services from different perspectives for the rural people where health care facilities are poor(More)
This paper describes an on-line e-voting system security implementation to reduce attacks. E-voting is gaining popularity in applications that require high security. E-voting is the electronically voting process via Internet. The system represents security analysis against large-scale attacks performed by rationally thinking attackers. Electronic Voting(More)
This paper presents a novel approach to analyze the purity of pulse crops by applying machine vision technique. The research concentrated on describing issues related to the development and use of machine vision system for agricultural image interpretation especially for pulse crops. Pulse crops of different stages from different places were collected,(More)
Long Term Evolution (LTE) is the new standard specified by Third Generation Partnership Project (3GPP) on the way towards the 4G mobile network. The LTE introduces enhance data link mechanisms to support successful implementation of new data services across the network. The incorporated scheduling mechanisms can significantly contribute to this goal. In(More)
In distributed data mining, secrecy of private data input of parties with similar background, is achieved by Secure Multi Party Computation (SMC). One of the mostly used tool of SMC is secure sum protocol which has been modified by researchers using many techniques to provide utmost security. In this paper, we propose another novel secure sum protocol to(More)
