Optimal High-Performance CMOS Self Cascode Current Mirror
In this paper, the current mirror presented, having low voltage and mixed mode structure has been proposed. The performance of self-cascade MOSFET current mirror is optimized with high output impedance and can operate at 1 V or below. This review paper presents a comparative performance study of self cascode current mirror with other current mirrors.To meet the need of the present era of low power portabale electronic equipment, many voltage design technique has been developed. This led to analog designers to look for innovative design technique such as self-cascade CMOS current mirror. In this paper investigate the merits and demerits of various current mirror circuit. For this first, develop basic current mirror and then cascode current mirror, Wilson current mirror and finally current mirror based selfcascode current mirror. The result is analyzed through spice simulation

A Novel Approach of Sensorized Glove for Paralyzed Person
The master purpose of the paper is to build sensorized glove system, designed to provide a comfortable communication using synthesized speech for the convenience of the paralyzed person. Usually, a paralyzed people with half of their body paralyzed (speechless) communicate with society through their sign language which is difficult to be understood by the majority of people. The intended system is configured to solve this problem. The movement of user’s finger of this glove will be changed into synthesizing speech to carry an audible message to receivers. The glove is occupied with the no of flex sensors which are constructed using bend sensitive resistance element. For every particular movement, flex sensor generates a proportional change in resistance of various elements. This mechanism sends a unique set of signal to microcontroller and voice IC which is pre-programmed to give the desired command. Thus, the developed system is used to establish a communication bridge among paralyzed (or speechless) and normal person.

Study of Concrete as Partially Replacement of Cement with Coal Bottom Ash (CBA)
The coal-fired thermal power plants are the main source of coal bottom ash. Coal Bottom Ash is used as a replacement of both sand and cement depending on the size of bottom ash. The present study will provide the better understanding of mechanical and durability properties of concrete in which cement is partially replaced with bottom ash. The present thesis would contribute to the efforts being made in the field of concrete technology towards the development of concretes possessing good strength and durability properties along with economic and ecological advantage. Based on the study, valuable advice will be given to concrete structures. In the present experimental study, the various strength properties like the compressive strength of cement mortar and concrete and also durability properties like Acid attack and water absorption test on both ordinary concrete and coal bottom ash Concrete, best coal bottom ash concrete mix is carried out and compared with ordinary concrete mix for economic and ecological study. In this study different percentage of ordinary and ground coal bottom ash is used. It was found that with an increase in the amount of coal bottom ash, standard consistency, initial and final setting time increases at the same time workability of concrete decreases. It was also found that initial days strength is less for bottom ash concrete compare to control mix, but as the age increases, they show good improvement in strength due to the pozzolanic reaction. Optimum dosage is observed to be 5% GBA which shows more strength compared to control mix at 56 days. It was found that with an increase in the amount of bottom ash resistance to acid attack increases. GBA shows more resistance to acid attack compared to OBA. With the increase in the amount of bottom ash water absorption capacity of concrete increases, also as the age increases for all the mix water absorption capacity decreases. It was also found that at optimum dosage i.e at 5% replacement of cement with GBA it is also economical and also the amount of CO2 Emitted is also decreased that means it is also environmentally friendly compared to control mix.

An Experiment of Concrete Partially Replacement of Brick Kiln Dust
Sustainable resources management and development have been at the forefront of important issue concerning the construction industry for the past several years. Specifically, the use of sustainable building materials and reuse waste materials is gaining importance and becoming common place in many areas. As one of the most commonly used construction materials in the world, concrete composed of natural aggregate, natural sand, cement and water, out of these raw material for concrete, cement can be manufactured in industries but natural aggregates are non renewable resources and depleting at an alarming rate, results in scarcity of good quality natural occurring aggregates (coarse and finer one). In the present study the hardened properties like compressive strength, split tensile strength, and also durability properties like, CSAT and UPV test were carried out on Brick kiln dust concrete. The percentage of bricks kiln dust that partially and fully replaced by fine aggregates by weights were 0%, 10%, 20%, 30%, 40% and 50%. Experiments were conducted for both Ordinary Concrete and bricks kiln dust Concrete with different percentages of BKD. It is observed from the experimental results and its analysis, that the compressive strength of concrete, splitting tensile strength of concrete increases with addition of low Percentage of bricks kiln dust. The results show that the optimum replacement of recycled bricks kiln dust with fine aggregates was 30%. Up to 30% replacement, it is possible to gain the same strength as conventional concrete

A Study of Professionalism of College Teachers
The present study is related to measurement of professionalism of college teachers and to find out whether is there any significant difference towards professionalism of college teachers as far as the gender of the teacher , teachers working in various faculties and teaching experience are concerned. In this study, a Likert type five point attitude scale of twenty statements was developed and used by the researcher. Fifty six teachers working in different stream of Rajkot (Gujarat) were selected as the sample, among them 28 were male teachers and 28 were female teachers. Analysis and scoring of the study were done by t-Test and f-Test. The findings revealed that Gender, faculties i.e. Arts, Science, Commerce & Education and teaching experience had significant effect upon teachers attitude towards professionalism

A Survey on Detection of Glaucoma using Fundus Images
Glaucoma, an eye disease, is often referred to as the silent thief of sight. The damage done by glaucoma is irreversible. There are many types of glaucoma. Early detection and treatment of glaucoma is the only solution. Till date, many works have been done towards automatic glaucoma detection using Fundus Images (FI) by extracting structural features. Structural features can be extracted from optic nerve head (ONH) analysis, cup to disc ratio(CDR) and Inferior, Superior, Nasal, Temporal (ISNT) rule in Fundus Image for glaucoma assessment. But unfortunately, the works till date fall short of expected accuracy in this regard. A review of automated glaucoma detection techniques is presented in this paper.
