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.

FEASIBILITY STUDY OF HYBRID; SOLAR AND BIOMASS POWER PLANT by Aanchal Jain 

Abstract
The thesis is the study of combined solar and biomass hybrid arrangement for the generation of electric power. In developing country like India, the electricity demand is rising continuously but the coal reserves for electricity generation are at the verge of depletion. So there is a need of paying attention towards the alternative sources of energy generation. Renewable energy sources are the best choice as they provide clean energy and overcome global warming. But there are certain problems in operating these sources as stand-alone systems. So it will be highly beneficial if both stand-alone systems work together as hybrid system because hybrid system will provide reliable and continuous power without depending upon main system and support farmers financially by consuming biomass from their fields. The present study intends to fulfill high electricity demands by utilizing solar  energy and biomass (agri-residue) potential available in different villages of Hoshiarpur. The objective of thesis is to investigate the feasibility of hybrid solar-biomass power plant in village Binjon in Hoshiarpur district of Punjab. On the basis of data collected from different organizations and dealers, the biomass potential, per unit cost of generation from hybrid system and payback period is analyzed using MATLAB. The proposed hybrid system is designed with per unit cost of Rs 8.39. Less per capita expenditure is an index of development of any nation and by using such hybrid systems we can get less per capita expenditure values

Durability Properties of Self Compacting Concrete with Recycled Aggregate and Silica Fume by Mohd Ishfaq 

Abstract
Concrete is widely used construction materials. As we know, it is a mixture of coarse aggre-gates, fine aggregates, binded together by cement with addition of water. Concrete which is highly flow able and can fill the form work under its own weight, consolidates without any mechanical vibration is known as selfcompacting concrete, thus cause self-compaction. Such concrete accelerate the time of placement, reduce the labour work needed for consolidation, finishing and reduces environmental pollution. The so called first generation SCC is used mainly for repair applications and in restricted areas where it is not possible to reach easily, comprising sections that present limited access to vibrate. It has been used in applications justifying the higher material and quality control cost when considering the simplified placement and handling requirements of the concrete. Silica fume is one of the best improvements of the rheological as well as the mechanical and good chemical properties. It also improves the dura-bility of the concrete. In this present study, tests on replacement of coarse aggregates with recycled aggregates and replacement of silica fumes with cement had been done. Tests were conducted for fresh prop-erties of self compacting concrete, i.e. filling ability, passing ability, segregation resistance, so as for obtaining fresh properties according to SCC EFNARC 2002 concrete mix. The different durability properties such as chloride penetration depth, abrasion resistance, were determined on various concrete mixes. Their compressive strength was also found. Replacement by silica fume decreases chloride penetration depth, depth of wear. Concrete mix having 50% recycled aggregate and 10% silica fume replacement had comparable durability in term of the chloride depth, abrasion resistance.
