An understanding of the mechanisms of heat transfer is becoming increasingly important in today’s world. Conduction and convection heat transfer phenomena are found throughout virtually all of the physical world and the industrial domain. A thermal insulator is a poor conductor of heat and has a low thermal conductivity. In this paper we studied that Insulation is used in buildings and in manufacturing processes to prevent heat loss or heat gain. Although its primary purpose is an economic one, it also provides more accurate control of process temperatures and protection of personnel. It prevents condensation on cold surfaces and the resulting corrosion. We also studied that critical radius of insulation is a radius at which the heat loss is maximum and above this radius the heat loss reduces with increase in radius. We also gave the concept of selection of economical insulation material and optimum thickness of insulation that give minimum total cost.

The Semantic Web is deemed to be the next major step in associating information in the web. It facilitates the linkage of data between two related sources and to be understood by the machine. Ontology is the essential building block of the semantic web for making the machine to communicate with other machines. Constructing the ontology for the general domain is very tedious and the construction of Medicinal plant ontology to be one of the most useful ontology for the average person to understand the usage of medicinal plants. Earlier research on ontology design methodologies shows that constructing ontology using manual process is tedious, but it is difficult to create the ontology automatically, since the sources of the input are in different forms, like, structured, semi structured, or unstructured data. In this paper, we present an automated ontology construction methodology for the medicinal plants. Java is used to extract the Wikipedia web pages related to medicinal plants, Java enabled application (Jena) is used for the automated construction of ontology, and Protégé is used for verifying the consistency of the ontology. Jena with SPARQL is used for inferring the usage of Indian medicinal plants. An Automated Knowledge framework for the Indian Medicinal Plants (AKIMP) is developed based on this proposed concept. The system is exhibited for fifty thousand concepts and gives the related information from Traditional Knowledge Digital Library (TKDL)[12] and Wikipedia web pages. Thus, it is possible to construct the automated knowledge base to retrieve the required resultant webpage based on the users’ need. This automated ontology construction methodology is an improvised method in analyzing the use of medicinal plants.

Pages: 13 - 16
Online wellness programs have been assisting well-being condition monitoring, illness modelling and validation OF grounded medical treatment by medical text mining. There exists a discernible gap in community based health forums between the online health seekers and providers. A cavernous learning structure is used to infer the diseases given the queries of health seekers. This scheme has two key components. The first globally mines the discriminant medical signatures from raw features. The second estimates the raw features and their signatures as input nodes in one layer and hidden nodes in the subsequent layer. The inter-relations between these two layers are found. All-encompassing trials on a real-world dataset labelled by online doctors show the noteworthy performance gains.

Pages: 17 - 23
Nowadays, authentication is one of the important fields in information security. Strong text-based password could provide certain degree of security level. However, the fact that, those strong passwords are difficult to memorize by the users. Graphical authentication has been proposed as an alternative solution to text-based authentication. Many researches shows that humans can remember images better than text. In recent years, many networks, computer systems and Internet based environments used graphical authentication technique for authentication. But this graphical authentication technique has many limitations. CAPTCHA is a programme that protects website against bots by generating and grading tests that human can pass but current computer program cannot. This paper present a new technology called Captcha as gRaphicalPassword (CaRP). CaRP combines both CAPTCHA and graphical password scheme. CaRP offers protection against dictionary attacks, relay attacks, shoulder surfing attacks. With the rapid development of internet, the number of people who are online also increases tremendously. The misuse and abuse of internet is growing at an alarming rate. Restriction of access is performed by introducing the concept of blacklisting of IP address.

Pages: 24 - 28
For concrete construction, one problem that a constructor often encounters is that there is a large amount of fraction of reinforcing steel caused by cutting. This study shows a method of reducing waste from the cutting. The reinforcing steel used in concrete is virtually 100% recycled from other metal products. More than 7 million tons of scrap steel is recycled into reinforcing bars every year, virtually the entire feedstock. This recycling avoids massive energy expenditure - one ton of steel reinforcing bars would otherwise require about 2,500 pounds of ore, 1,400 pounds of coal, and 120 pounds of limestone. The steel industry believes that sustainable development must meet the needs of the present without compromising the ability of future generations to meet their own needs. Within this, a green economy delivers prosperity for all nations, wealthy and poor alike, while preserving and enhancing the planet’s resources. The main objective of this study is to experimentally investigate the flexural behavior of RC beam containing coupler rebars and welded rebar and the experimental parameter is grade of concrete. Coupler and welding methods are used in this study to find which method will give more strength between both. Experimental results revealed that the coupler beam gives more strength than the welded beam but not more than the control beam specimen for 7 days and 14 days and 28 days. From the above observation it is suggested that we can use couplers in the rebar joining than the welding of rebar which gives better strength and also avoids congestion.

Pages: 37 - 42
The project first makes the attempt to formally address the problem of authorized data deduplication. Here apart from the traditional deduplication systems, the differential privileges of users are further considered in duplicate check besides the data itself. It shows the proposed authorized duplicate check scheme incurs minimal overhead compared to normal operations. The one of the advantage of cloud is that it is cost efficient, so cloud users can tolerate a certain amount of delay in order to reduce cost during information retrieval. The two issues which is addressed here in such an environment is privacy and efficiency. Here two efficient information retrieval for ranked query (EIRQ) schemes to reduce querying overhead is introduced. In EIRQ users can retrieve files on demand by choosing queries of different ranks. It is useful when a large number of matched files are there and the user only needs a subset of them.

Pages: 43 - 53
The aim of this study is to evaluate the performance of students using a fuzzy expert system. The fuzzy process is based solely on the principle of taking non-precise inputs on the factors affecting the performance of students and subjecting them to fuzzy arithmetic to obtain a crisp value of the performance. The system classifies each student's performance by considering various factors using fuzzy logic. Aimed at improving the performance of fuzzy system, several defuzzification methods other than the built methods in MATLAB have been devised in this system for producing more accurate and quantifiable result. This study provides comparison and in depth examination of various defuzzification techniques like Weighted Average Formula (WAF), WAF-max method and Quality Method (QM). A new defuzzification method named as Max-QM which is extended from Quality method that falls within the general framework is also given and commented upon in this study.
