A study has been made to determine the optimum percentage of manufactured and for making High Performance Concrete. Concrete cubes of size 100 x 100 x 100 mm, Cylinder specimens of size 150 mm diameter and 300 mm height and Prisms specimens of size 100 x 100 x 500 mm were prepared for the High Performance Concrete with partial replacement of natural sand by M-sand along with partial replacement of cement by 7.5 % Silica fume constantly for all mixes. The compressive strength, Split Tensile Strength and Flexure Strength and were found out at 7, 14, and 28 days. The concrete used in this investigation was proportioned to target a mean strength of 60 MPa and W/B ratio was 0.32. The investigation revealed that the concrete exhibits excellent strength with 60 % replacement of natural sand by manufactured sand with 7.5 % Silica fume. Hence M-Sand can be used in concrete as a viable alternative to natural sand for the Environmental friendly High Performance Concrete in the Construction industry.

Abstract: This paper addressed that most large companies have been adopting some form of research and Development (R & D) activities. A survey of executives belongs to technology-intensive (T-I) industries in India showed that R & D was the most important key category for investment. In many cases, the implementation of an R &D activity was a long and expensive ordeal that involved extensive reconstructing of business and reengineering of processes. While the potential benefits of R & D have been extolled frequently and much has been written about individual company experiences, only limited evidence has been produced that implementation of R & does, on average, lead to enhanced performance. Several research studies have validated that research and innovation provides productivity and profitability advantages. This study seeks to extend prior work by performing a longitudinal study of implementation of R & D activities in a specific industry.

Abstract: Normally the machine which is used to print woven fabric is used to print knitted fabric. But the property of the knitted fabric is different from woven fabric. Tubular knitted fabric is having two layers when flattened. Fabric is elastic in nature. Normal machine can print one side and has to dry the paste second side again and we have to heat the fabric to dry to finish the printing of tubular knitted fabric it has to be printed side by side. But in this present machine both sides can be printed by passing the fabric and paste and again we have to dry and print the second side. But in this method printing on both sides can be printed simultaneously. So the fabric can be heated only once to complete the printing. So the thermal energy required to heat the fabric once is conserved and is equal to Cpf (T2-T1) per kg of fabric printed.

Abstract: Textile printing is a term used for applying colours to fabric in different designs and patterns. In textile printing the whole fabric s uniformly dyed and the patterns are well defined. The textile fabric printing forms a part of the textile finishing process. In fabric printing, the designs are applied to the fabric by three methods-roller method, flat screen and rotary screen method. Rotary printing is where images that are to be printed are curved around the cylinder. Any kind of substance can be printed using a rotary printer such as paper, cloth, etc. The rotary printer consists of a tubular screen through which print paste is forced into the fabric. The rotary printing is most commonly used these days for apparel fabrics. The knitted fabric is mostly printed in the rotary as there is no stress such as stretching and pulling of the fabric should not take place. The existing rotary printing devices are designed to print woven fabric and also knitted fabric. These machines can print the fabric only on one side. Tubular knitted fabric has two layers when flattened. We have to print the fabric one side, dry and again we have to batch and print on another side. But the present machine can print the fabric on both sides simultaneously. The rotary screen circumferences meeting tangentially and rotating in opposite directions. The edges of the squeezing blades and the tangential contact line of two screens meet in a single line. The fabric is fed from top to bottom at the same speed as that of the peripheral speed of rotary screen. The two screens are connected with two end ring which are connected to gears which in turn is connected to a single shaft. The fabric passes between two screens and the two squeezing blades squeeze the printing paste and the colour penetrates through the screen and gives the desired design. To dry the printing paste on two sides ' single pass through drier will enough. To complete the printing on both sides of the tubular knitted fabric single pass will do. But in conventional machine the fabric has to be dried twice to get the print on both sides. Instead of heating fabric twice it is enough to heat fabric only once to complete print on both sides. Thermal energy required to heat the fabric one time is saved by this machine.

Abstract: Process control applications need smooth operation and noiseless operation of BLDC motor is required. Owing to many advantages of BLDC motors, they possess a trade off they exhibit torque pulsations. These pulsations can cause acoustical noise and vibration; this will entirely affect the system in high precision and high stabilization applications. In higher speeds torque pulsations can be filtered out by inertia of the load itself. However, at low speeds, when they are most noticeable, torque pulsations can greatly limit the performance. Torque ripple is caused by both the BLDC motor and the controller design .A novel approach is presented in this paper to minimize the ripples by developing a Cascade type hybrid controllers, which will have very good performance which will reduce the ripples in torques. PID controllers and Neural Netrwork controllers are designed and tested in the BLDC motor by using MATLAB.

Abstract: Commodity driven composites which are categorized as lower price composites are mostly made of natural fibre. Natural fibre composites are mainly price-driven commodity composites, which have useable structural properties at relatively low cost. The manufacture, use and removal of traditional composite structures usually made of glass, carbon and aramid fibres are considered critical because of the growing environmental consciousness. Therefore this research work involves eliminating the problem involved in the existing composite with the help of natural fibres, over traditional reinforcing fibres such as glass and carbon. The following work illustrates the manufacture and tested values of one such composite manufactured from plant fibre which is used as green manuring plant called Crotalaria juncea. Woven orientation of biaxial, biaxially stitched and unidirectional mat, in 2 layers and 3 layers separately are mixed with polyester resin and plates are prepared and the results acquired derive the usefulness of the material for required application.

The following work illustrates the manufacture and tested values of one such composite manufactured from plant fibre which is used as green manuring plant called Crotalaria juncea. Retted fibres after alkali treatment is taken and plate preparation is done using polyester resin mixed with random orientation of the fibre of lengths 20, 30, 40 and 50mm to a weight of 21, 28, 31, 35, 42 and 45 g as the first part. In the second stage woven orientation of biaxial, biaxially stitched and unidirectional mat, in 2 layers and 3 layers separately are mixed with polyester resin and pates are prepared. Both the stages are tested for tensile and flexural properties such that the breakeven value of each property is analyzed, and the results acquired derive the usefulness of the material for required application.
