Optimal Assembly Plan and Control of Networks
The routing problem of jobs/customers arriving in a network of parallel queues, constitutes a problem of queuing theory with important applications. Consider N parallel queues each with finite buffer size. The buffer size of queue i is denoted by Ni and it is equal with the number of processors in the queue. Jobs arrive according to a Poisson process with rate λ. A controller assigns new arrivals to queues. Arriving jobs, that find all buffers occupied, are lost according to the system. A job assigned to a processor may not change in the future. The time it takes for a job to be processed is exponentially distributed with rate μ. Processing times and arrival times are all assumed to be independent. The problem is the determination of the assembly plan of such systems and their control. The criterion that is used is the minimisation of sum of the services quality cost and server holding cost.
Optimal server allocation; optimal control of parallel queues; service level agreement.

|Adaptive Bounding Box Searching Method Implementation for the Character Number Motor Vehicles Analysis|
Motor vehicle license plate detection system based on mobile is a motor vehicle license plate area detection system by using smart phone with windows phone operating system version 7.5. The pictures taken by smart phone camera are processed with high-pass convolution in order to get character objects on license plate. The outcome of convolution further is marking license plate's character candidates with adaptive bounding box searching method. License plate's character candidates obtained will be selected again to form a vehicle license plate. In this research 150 image samples were tested, where 50 images were tested with image taken distance of 1 – 1.5 meter, 50 images were tested with image taken distance of 1.5 – 2 meter, and 50 images were tested with image taken distance of 2 – 2.5 meter. From the research it was obtained that the highest success rate was at image taken distance of 1.5 – 2 meter which was 90%.

|Etude du comportement des objets java dans le Tas|
L'allocation et la libération explicite des données dans la mémoire provoquent une quantité importante d'erreurs dans les langages de programmation .Or, avec L'apparition du java comme un langage Orienté objet qui possède la technique de la gestion de la mémoire d'une façon automatique simplifie les programmes et élimine une préoccupation du développeur qui ne se soucie ni de l'allocation d'objet ni de sa libération, contribuant de ce fait à s'abstraire facilement du matériel .pour ceci un grand nombre de technique
ont été développées pour gérer la mémoire à objet automatiquement. Après une présentation de l'état de l'art dans ce domaine, on va pencher sur notre approche proposée pour gérer les objets java dans le Tas .on clôtura ce manuscrit par une simulation.

|Semantic Role Extraction and General Concept Understanding in Malayalam using Paninian Grammar|
The collection of methods by which human languages convey meaning is called meaning structure of a language. It includes many conventional form-meaning associations, word-order regularities, tense systems, conjunctions and quantifiers, and a fundamental predicate-argument structure. In the Dravidian language, Malayalam, the Karaka theory, is useful for both the syntax analysis and semantic analysis of Malayalam sentences. Here proposes a system that builds semantic structure from a given Malayalam text using semantic roles (karakas) extraction. Semantic structure can be utilized for solving many language computing tasks such as Conceptual Indexing, Conceptual searching and retrieval, automatic question answering, automatic text summarization, syntactic and semantic analysis of Malayalam documents, etc.

|Lossy and Lossless Current-mode Integrators using CMOS Current Mirrors|
Analogue design has been historically viewed both in voltage-mode and current-mode dominated form of signal processing. In literature wide variety of techniques and circuits are available for the design of different current-mode signal processing circuits suitable for VLSI implementation. In this paper we present the major current-mode building blocks using complementary CMOS current-mirror pairs such as current adders and current integrators (lossy and lossless). These building blocks form the basic constitutional blocks for the implementation of second-order continuous-time current-mode active filters. All the proposed circuits presented in this paper were tested in SPICE using 0.5μm CMOS process parameters provided by MOSIS (Agilent) and the results thus obtained were in accordance with the theoretical values.

|Information Extraction and Rule Prediction Using DiscoTEX|
Text Mining is a process of deriving high quality information from the text. Text mining usually involves processing of the unstructured document, extracting features from the document and storing it in the database and finally using KDD techniques rules are evaluated. IE module is use to convert the corpus text into a structured database from which rules are mined. This paper describes a system called DiscoTEX (Discovery from Text Extraction) which integrates IE(information extraction) module with the KDD module. For
DiscoTEX an IE learning system Rapier (Robust Automated Production of Information Extraction Rules) is used which automatically creates the structured database.

|Effects of Carburizing on Wear Properties of Steels|
The present investigation is the over view of carburizing process and its effect on wear properties various types alloy steels. Carburising is one of the process of surface hardening and sufficient toughness at the core for increasing hardness over the surface of steel component so that wear resistance at the surface of steel component of steel component can be improve. Aim of carburizing is to increasing carbon content in low
carbon steel at the surface.

|Enhancing collaborative filtering in music recommender system by using context based approach|
Recommender Systems analyse some user and item interactions to help users by recommending the most relevant, feasible and appropriate items from a wide range and pool of items and resources. We propose to enhance the collaborative filtering methodology in recommender systems by considering the content as well as the context based approach towards recommendation. The rating of items and the contextual information of users are expected to enhance the relevance constraint by taking into account the user's mood and activity implicitly by using respective API's to capture and consider the contextual features of the user. The methodology and technique of reduction based approach and user based rating prediction will be used to accomplish the desired results for the proposed recommender system.
