Abstract

The experiments were carried out to study the kinetics of mentha oil extraction from mentha leaves (Mentha arvensis L.) and the quality analysis was carried out for the oil extracted. The oil was extracted from mentha leaves at three different moisture contents of 74.30 per cent (fresh leaves), 42.30 per cent (shade dried) and 19.35 per cent (sun dried) using hydro distillation method. Various physicochemical tests were carried out on the oil extracted. The results revealed that the hydro distillation process took more time for oil extraction and oil recovery was less. Various physicochemical properties such as acid value, refractive index, specific gravity, saponification values and solubility in water did not show significant variations with respect to oil extracted by differently pretreated mentha leaves.

Abstract

The objective of this paper was to investigate experimentally the effect of water-cooled condenser in a household refrigerator. The experiment was done using HFC134a as the refrigerant and Polyol-ester oil (POE) oil as the lubricant. The performance of the household refrigerator with air-cooled and water-cooled condenser was compared for different load conditions. The results indicate that the refrigerator performance had improved when water-cooled condenser was used instead of air-cooled condenser on all load conditions. Water-cooled condenser reduced the energy consumption when compared with the air-cooled condenser between 8% and 11% for various load conditions. There was also an enhancement in coefficient of performance (COP) when water-cooled condenser was used instead of air-cooled condenser. The water-cooled heat exchanger was designed and the system was modified by retrofitting it, instead of the conventional air-cooled condenser by making a bypass line and thus the system can be utilized as a waste heat recovery unit. The hot water obtained can be utilised for household applications like cleaning, dish washing, laundry, bathing etc. Experimental result shows that about 200 litres of hot water at a temperature of about 58ºC over a day can be generated and thus the system signifies the economic importance from the energy saving point of view.

Abstract

With the advent of cloud computing, it has become increasingly popular for data owners to outsource their data to public cloud servers while allowing data users to retrieve this data. For privacy concerns, secure searches over encrypted cloud data has motivated several research works under the single owner model. However, most cloud servers in practice do not just serve one owner; instead, they support multiple owners to share the benefits brought by cloud computing. In this paper, we propose schemes to deal with Privacy preserving Ranked Multi-keyword Search in a Multi-owner model (PRMSM). To enable cloud servers to perform secure search without knowing the actual data of both keywords and trapdoors, we systematically construct a novel secure search protocol. To rank the search results and preserve the privacy of relevance scores between keywords and files, we propose a novel Additive Order and Privacy Preserving Function family. To prevent the attackers from eavesdropping secret keys and pretending to be legal data users submitting searches, we propose a novel dynamic secret key generation protocol and a new data user authentication protocol. Furthermore, PRMSM supports efficient data user revocation. Extensive experiments on real-world datasets confirm the efficacy and efficiency of PRMSM

Abstract

In today's world, network is becoming compulsory technology even in a normal human life ranging from a student to a professional. In every field networks are being used. In olden days networks are formed by connecting the computer systems through cables. As the days are going on more number of computer systems are connected to the network. As a result network size gets increased and networks like LAN, MAN, WAN came into existence. Huge networks with cables has so many disadvantages like, if the cable is damaged there will be no communication between the system, and since one cable may be shared between many users the communication may become slower, and the users may put heavy load on the communicating cable than it's capacity which may cause congestion. To overcome all these demerits of wired networks wireless networks are proposed. In wireless networks there are no communicating physical cables. The system will communicate with each other by using radio or infra red waves which travels through air. The wireless networks will also suffer from so many problems like node mobility, , high error rate, long latency and even congestions. In this paper we are going to discuss various congestion control mechanisms in wired and wireless networks and their merits and demerits

Abstract

The main objective of the paper is to Enhance distributed load rebalancing algorithm to cope with the load imbalance factor, movement cost, and algorithmic overhead. The load rebalance algorithm is compared against a centralized approach in a production system and the performance of the proposal implemented in the Hadoop distributed file system for cloud computing applications. The cloud applications process large amount of data to provide the desired results. Data volumes to be processed by cloud applications are growing much faster than computing power. This growth demands on new strategies for processing and analyzing the information. The paper explores the use of Hadoop Map Reduce framework to execute scientific workflows in the cloud. Cloud computing provides massive clusters for efficient large computation and data analysis. In such file systems, a file is partitioned into a number of file chunks allocated in distinct nodes so that Map Reduce tasks can perform in parallel over the nodes to make resource utilization effective and to improve the response time of the job. In large failure prone cloud environments files and nodes are dynamically created, replaced and added in the system due to which some of the nodes are over loaded while some others are under loaded. It leads to load imbalance in distributed file system. To overcome this load imbalance problem, a fully distributed Load rebalancing algorithm has been implemented, which is dynamic in nature does not consider the previous state or behavior of the system (global knowledge) and it only depends on the present behavior of the system and estimation of load, comparison of load, stability of different system, performance of system, interaction between the nodes, nature of load to be transferred, selection of nodes and network traffic. The current Hadoop implementation assumes that computing nodes in a cluster are homogeneous in nature.

Abstract

Wireless Sensor Network (WSN) consists of mostly tiny, resource-constraint, simple sensor nodes, which communicate wirelessly and form ad hoc networks in order to perform some specific operation. Due to distributed nature of these networks and their deployment in remote areas, these networks are vulnerable to numerous security threats that can adversely affect their proper functioning. However, their characteristics such as the broadcast nature of the medium, spatial diversity, and significant data redundancy, provide opportunities for new design principles to address these problems. There has been recent interest in employing network coding in wireless networks. This paper explores the case for network coding that offers packet flow un traceability and message content confidentiality against traffic analysis using WSN which gives better performance in WSN life span and nodes energy consumption. Theoretical analysis and simulative evaluation demonstrate the validity and efficiency of the proposed scheme.
