The RETE algorithm is an efficiently organized pattern matching algorithm for implementing production rule systems, used to determine which of the production rules should fire based on its data store. This paper presents how RETE algorithm can be used to improve the efficiency of expert system recommendation. The ‘COURSE FINDER’ is an expert undergraduate course recommendation system. This system...
Genetic algorithm is one of the optimization techniques, successfully applied in nuclear reactor environment for a variety of applications. Nuclear fuel management optimization is a classical nuclear engineering problem, which has been studied extensively and several techniques, including genetic algorithms, have been used for its solution. The study presented in this paper addresses the overall procedures...
Color image segmentation is an emerging topic in current image processing research. There exist different techniques for the same. Region based approach like watershed algorithm is one of them. But, watershed approach normally results in problems like over segmentation, noise, etc. In this paper, an efficient approach for the color image segmentation is proposed. Here, the input image is converted...
In this model, we propose an innovative recruitment system using social networking websites like Twitter and LinkedIn along with code repository hosting website GitHub and competitive coding platforms like SPOJ. It is aimed to develop advanced search engines to automatically sort the job-seekers based on job offer requirements using various data mining and machine learning techniques. Vritthi allows...
MANET is collection of wireless nodes which are connected to each other, but all nodes are independent. They can communicate each other via intermediate nodes or directly. In order to increase the lifetime of the network, routing must be energy efficient. Routing protocols like DSR, ECDSR, AODV, TORA, DSDV, EEAODR, and EPAR are proposed for MANET. Design of energy efficient routing protocol is the...
EEG contains immense information about the brain activity which cannot be understood completely by visual inspection. Powerful signal processing algorithms in EEG analysis can greatly assist the physicians and neurologists to extract such hidden information. It has been found that EEG being a time-varying and non-stationary signal, can be analyzed by non-linear methods. In this paper we tried to evaluate...
Down syndrome is a genetic disorder in which disrupts infants, physical and cognitive development. Down syndrome is characterized by the absence of nasal bone during the late first trimester of pregnancy. Presently Down syndrome is identified by visually examining the ultra sonogram image of foetus of 11 to 13 weeks of gestation for the presence of nasal bone. The visually identification by the change...
Modern active phased array radars are made to optimize the size, weight and power without compromising its capability to combat with advanced electronic warfare. To accomplish this task, the signal is digitized at element level or at sub-array level and processed with the help of advanced digital signal processor. Proving the capabilities of this firmware at bench level helps to reduce the overall...
In this competitive world, business is becoming highly saturated. Especially, the field of telecommunication faces complex challenges due to a number of vibrant competitive service providers. Therefore, it has become very difficult for them to retain existing customers. Since the cost of acquiring new customers is much higher than the cost of retaining the existing customers, it is the time for the...
Many of the text mining applications contain a huge amount of information from document in the form of text. This text can be very helpful for Text Clustering. This text also includes various kind of other information known as Side Information or Metadata. Examples of this side information include links to other web pages, title of the document, author name or date of Publication which are present...
This paper presents speech encryption based on four-dimensional hyperchaotic systems. Higher order chaotic systems can generate pseudo random numbers (PRN) of more complex dynamical properties. Hyper chaotic sequence is proofed with good randomness and unpredictability. In this approach, the speech scrambles are compressed by DCT to reduce residual intelligibility. Coefficients are then masked by...
Adapting to the latest technological advancement is the only means for sustainability and growth for any organization in this era of fast growing business world. Cloud computing have proved to be a great boon for business development as it provides servers across the globe for storing data securely and performing computations on them. However security challenges still pose a great threat for using...
High performance applications requires high processing power to compute highly intensive and complex applications for research, engineering, medical and academic projects. In the traditional way, an organization will have to pay very high costs to run an HPC (High Performance computing) application. The organization has to purchase highly expensive hardware for running an HPC application and maintaining...
Hierarchical clustering is of enormous importance in data analytics especially because of the exponential growth of the real world data. Frequently these data are unlabelled and there is small prior domain knowledge offered. In this work the plan is to improve the efficiency by introducing a set of methods dealt with synthetic and real data on agglomerative hierarchical clustering followed by k-means...
Search reranking is regarded as a common way to boost image retrieval precision. The problem is not simple especially when there are multiple features to be considered for search, which often happens in image retrieval. This paper proposes the combination of Circular reranking and Time-based reranking methods for improving the precision of image retrieval. Circular reranking utilises multiple features...
MANET, a self-organizing network of various devices responsible for seamless communication. Routing protocols involved in the communication adopts new strategies to assure energy, security, traffic minimization, overhead. Dynamic nature of the MANET requires the modification in routing protocols for performance improvement. This paper presents the detailed survey of strategies involved in the implementation...
In today's world, the daily hustle-bustle does not permit a human being to devote time for manually summarizing various lengthy documents. Hence it is of utmost importance to devise an application that will facilitate automated text summarization. Not only will this application save time but also render higher scope of efficiency. This application will allow the user to automatically summarize relevant...
