Speech Recognition System Based on Hidden Markov Models



INTRODUCTION


The field of Automatic Speech Recognition (ASR) is about 60 years old.
First speech recognizer was invented at BELL LABS in 1950
Development of ASR increased gradually until the invention of Hidden Markov Models

A Web Service for evaluation of load balancing strategies for distributed web server systems

Number of users accessing the Internet is increasing quite rapidly and it is common to have more than 100 million hits a day for popular web sites. For example, netscape.com website receives more than 120 million hits a day. The number of users is expected to continue increasing at a fast rate and hence any website that is popular, faces the challenge of serving very large number of clients with good performance. Full mirroring of web servers or repl ....etc

A Review of Hidden Markov Models for Context-Based Classification
Historical Note
• “Classification in Context” was well-studied in pattern recognition in the 60’s and 70’s
– e.g, recursive Markov-based algorithms were proposed, before hidden Markov algorithms and models were fully understood
• Applications in
– OCR for word-level recognition
– remote-sensing pixel classification
Context-Based Classification Problems
• Medical Diagnosis
– classification of a patient’s state over ....etc

ABSTRACT
The increase in Internet-based transactionsand communications offers new opportunitiesfor hackers to disrupt business operations withDDoS attacks. Organizations that are notadequately protected risk losing customers,revenue, and their good reputations. Thisthesis discusses the challenges of identifying,countering, and avoiding crippling DDoSattacks. With the proposed comprehensiveSelf-Defending Network, organizations candeploy layers of defense to detect and mitigatethe effects of DDoS attacks. The convenience,efficiency, and ....etc

ABSTRACT
The concept of a middleware was introduced to facilitate communication between entities in a heterogeneous distributed computing environment. The main task of an event-based middleware is to disseminate data to all interested parties in a largescale distributed system. Hence, an event model is needed to describe how data, and interest in that data, is expressed in the system i.e. event publication and event subscription respectively. In our system, we represent an event as an object and the event model is illustrated using a sample a ....etc

Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ....etc
