SVM BASED SPOKEN NUMERALS RECOGNITION FOR PUNJABI LANGUAGE by Satbir Kaur 

Abstract

The advances in digital signal processing technology had led the introduction of speech processing in several applications like speech compression, enhancement, synthesis, and recognition. In this thesis the problem of speech recognition is studied and a speaker dependent, medium vocabulary, isolated numerals speech recognition system has been developed for Punjabi language. The study implements the Support Vector Machine based isolated numerals speech recognizer in three steps. The primary step performs the end point detection, framing and windowing of the speech signal. The second step includes speech feature extraction using Mel Frequency Cepstral Coefficients. Finally, in the last step the Support Vector Machine is primarily used as recognizer and classifier for numeral of Punjabi language. The system is ready to understand the spoken utterances in Punjabi language, by removing the unwanted noise and unsuitable data from the speech signal and then translating the speech wave into quality of feature vectors. These vectors are given to SVM to predict the spoken word in written form. The Support vector machine classifier is wide used and given high accuracy. SVM has the ability to deal with high dimensional knowledge and is used in many real world problems like text categorization, character recognition and classification.

STUDY OF SELF COMPACTING CONCRETE MADE WITH BINARY AND TERNARY CEMENTIOUS BLENDS OF GROUND GRANULATED BLAST-FURNACE SLAG AND RICE HUSK ASH by Brahamjot S. Chaswall 

Abstract

Sustainable development in construction industry is aimed at improving the quality of life for everyone now and for the next generations. It encompasses environmental, economic and social dimensions, as well as the concept of stewardship, the proper management of resources used in construction and particularly concrete production in India being the second largest producer of cement in the world. The future challenge for the construction industry in India is clearly to meet the growing demand for infrastructure development and housing while at the same time limiting the impact of its burdens in CO2 emissions due to construction by use of alternative materials in construction and supplementary cementing materials as partial replacements to Ordinary Portland Cement.As we know concrete occupies unique position among the modern construction materials. Concrete is a material used in building construction, consisting of a hard, chemically inert particulate substance, known as aggregate (usually made for different types of sand and gravel), that is bond by cement and water. Concrete is normally used in the frame structure. But there is some limitation like compaction, surface finishes, maintaining strength at congested area. Due to these limitations we are trying to make self- compacting concrete with the use of mineral admixture. Self-Compacting Concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. Self-Compacting Concrete has properties that differ considerably from conventional concrete. This study investigates the workability and Compressive Strength properties of Self-Compacting Concrete containing Ground Granulated Blast Furnace Slag and Rice Husk Ash with super plasticizer and viscosity modifying agent. EUCOPLACANT 721 was used as super plasticizer and STRUCTRO 100 was used as Viscosity modifying agent. In this experimental program, trials were made at varying replacement levels (10%, 20%, 30% and 40%) of Ground Granulated Blast Furnace Slag and (5%, 10%, 15% and 20%) of Rice Husk Ash. The workability properties of SCC such as filling ability, passing ability and segregation resistance are evaluated using workability tests such as slump flow, V-funnel and L-Box tests. The compressive strength of the cubes at 7 days and 28 days are also obtained. The result obtained from the study proves that use of GGBS increases the Compressive strength of SCC by replacing cement to a percentage of 30% ,if the percentage is taken more than 30% the Compressive strength of SCC decreases. In case of GGBS and RHA combination the strength is highest by replacing cement with 5% of RHA and 30% of GGBS.
