Synthesis of Diallyl Thioether under the Influence of Ultrasound Assisted Multi-Site Phase-Transfer Catalysis Condition – A Kinetic Study |
||||||||
Allyl bromides afford the corresponding sulfide derivatives upon treatment with aqueous sodium sulfide under multi-site phase-transfer catalysts (MPTC) and ultrasound irradiation conditions. The use of phase-transfer catalysis and sonochemistry has been compared and demonstrated in these nucleophilic substitution reactions. The kinetics of reaction depends on the effect of amount of catalyst, agitation speed, quaternary ammonium salts, amount of sodium sulfide, amount of sodium hydroxide, organic solvents, temperature and frequency of the ultrasound waves on the conversion of allyl bromide was investigated in detail. A kinetic model was built from which a pseudo-first order rate law is sufficient to describe the behavior of the reaction. The observed peculiar phenomena were also explained satisfactorily.

||||||||
In this paper we have described the signature scheme inwhich an individual can sign a document ormessage onbehalf of entire group. Here, a group blind signaturescheme has been proposed. Our scheme combines the already existing notions of blind signatures and group signatures. It is an extension of Camenisch and Stadler'sGroup Signature Scheme [12] that adds the blindness property.One important requirement of
electronic cash systems is the anonymity of customers.Unconditional anonymity is also very well suited to support criminals inblackmailing...........

||||||||
A sensor interface device is essential for sensor data collection of industrial wireless sensor
networks (WSN) in IoT environments. The Internet of Things (IoT) environment, each sensor connected to the device is required to write complicated and cumbersome data collection program code. In the proposed method we overcome the drawback present in existing system by using wireless sensor network. We are designed a system by using ARM 32-bit micro controller which supports different features and algorithms for the development of industrial automation systems. Using ARM controller we can connect all types of sensors and we can connect 8 bit microcontroller based sensor network to ARM controller using different wireless technology called Zigbee. Many open source libraries and tools are available for ARM-Linux wireless sensor network development and controlling. We can monitor and control the wireless sensor network remotely using internet and web server.

A Review Paper on Earned Value Analysis |
||||||||
Earned value is the measurement of work. It is used to evaluate the progress of a project based on the cost of work performed up to the project status date. The earned value calculation enables to conduct comparative study of original cost estimate and the actual cost. This helps in evaluating economic status of the project. Despite of having various benefits, the earned value analysis (EVA) is not being used in India extensively as compared to developed countries. A detailed review on application of EVA has been presented in this paper.

Comparative Evaluation of Electrostatic Sprayer with Powered Mist Blower |
||||||||
Theknapsack mist blower is one of the most popular and versatile pesticide application equipment in India due to its simplicity, ease of operation and inexpensiveness. However these sprayers have to overcome certain constraints like low deposition efficiency, poor distribution and low penetration into dense plant canopy. The introduction of electrostatic sprayer could overcome these lacunas with its application efficiency by about 80% with 50% less spray chemical ingredients. Both the sprayers were evaluated for comparative assessment of performance both under laboratory and filed conditions. The evaluation was done for deposition efficiency and
biological efficacy............

An Efficient Biometric Multimodal Fingerprint and Iris using an SVM Classifier and Adaptive Neuro Fuzzy Inference System (ANFIS) |
||||||||
ecent times witnessed much advancement in the field of biometric and multimodal biometric fields. This is typically observed in the area, of security, privacy, and forensics. Even for the best of unimodal biometric systems, it is often not possible to achieve a higher recognition rate. Fusion of matching scores of multiple biometric traits is becoming more and more prevalent and is a very likely approach to boost the system's accuracy. The finger print and iris are among the most promising biometric authentication that can accurately identify and analysis a person as their unique qualities can be rapidly extracted during the recognition process. This biometric recognition and verification often deals with non-ideal scenarios such as faint images, off-angles, reflections, expression changes

Intrusion Tolerance System Using VM Balancing In Virtual Environments |
||||||||
Computing systems that provide useful services to clients are connected to the Internet. Unfortunately, there are malicious clients who make them susceptible to attacks. Even though security solutions such as an intrusion prevention or firewall can be used to protect such attacks, it is not always possible to defend systems against attacks completely. The studies on intrusion tolerant system (ITS) have been proposed to maintain the proper services in threatening environments. In this paper, we propose an ITS using VM balancing scheme which can balance online virtual machines within each of hosts. The proposed method reduces the damage of VM escape that allows an attack to move from one virtual machine to another virtual machine in a host. By this method, the proposed scheme can guarantee the minimum of services to clients, even under malicious intrusion such as VM escape.

A Comparative Study on the Efficiency of Koh Impregnated and H3PO4 Impregnated Jackfruit Leaf Based Carbon as Adsorbent for Removal of Ni from Its Aqueous Solution |
||||||||
This research work investigates the efficiency of H3PO4and KOH impregnated jackfruit leaf powder
based carbon as adsorbent to remove Ni from wastewater. The removal characteristics of Nickel using both the
adsorbents were investigated under various operating variables like contact time, adsorbent dosage, initial metal
concentration, solution pH, temperature and stirring speed. The results showed that the H3PO4impregnated
jackfruit leaf powder based carbon is a better adsorbent than the KOH impregnated adsorbent. The experimental
results were found to fit well with langmuirand freundlich isotherms.The maximum adsorption capacity of
theH3PO4impregnated adsorbentwas found to be 62.98 mg/g and that of the KOH impregnated adsorbent to be
54.66 mg/g.
