Footstep power generation using piezoelectric transducers
The man has needed and used energy at an increasing rate for the sustenance and well-being since time immemorial. Due to this a lot of energy resources have been exhausted and wasted. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India where the railway station, temples etc., are overcrowded all round the clock.When the flooring is engineered with piezoelectric technology, the electrical energy produced by the pressure is captured by floor sensors and converted to an electrical charge by piezo transducers, then stored and used as a power source. And this power source has many applications as in agriculture, home application and street lighting and an energy source for sensors in remote locations.

Offline handwriting recognition using neural networks
Handwriting recognition system can be defined as the ability of a computer to intelligently recognize the handwritten text by the user. The handwriting recognition is considered to be an open research topic due to the fact that every human being has a unique handwriting as well as there are numerous languages which are being used worldwide in written form. A neural network can be designed for recognizing handwritten texts in any language required. As different people have different handwriting styles, the task of recognizing the handwriting is a difficult task. As of today, the OCR (Optical Character Recognition) Engines are primarily focused on machine printed texts or handwritten texts which are written in block letters. By recognizing the texts in the handwritten text images by the user into letter codes is becomes usable digitally in computers and text processing applications.

Bioleaching of industrial waste foundry sand by Aspergillus sp. treated as biofertilizer for the growth of herbal plants – Coriandrum sativum.
The present work aims to investigate the potential of Aspergillus sp. in the bioleaching of waste foundry sand and to support the growth of Coriandrum sativum. The WFSs were from aluminum, iron and steel foundries. This study also assesses the availability of Al, Cd, Co, Cu, Fe, Mg, Ni, Pb, and Zn in WFS. Although there were differences in the amounts of metals accumulated by the various plant species, excessive amounts of heavy metals were not taken up, regardless of WFS treatment. Hence, our study is designed to bioleached the metals present in waste foundry sand using Aspergillus sp. and to use it as a biofertilizer for the growth of Coriandrum sativum. The waste foundry sand was collected from different regions around Chennai and Coimbatore districts. The physical properties such as coloration like (black, and light black). Texture (Round and spherical), Moisture (0.75, 0.97), temperature (Room Temperature), solubility (dissolved and settled) and pH were measured (5-9) using standard protocols. The chemical properties of treated and untreated waste foundry sand were observed. The analyzed shows increase the level of aluminum and iron and decreased levels of Copper and Zinc in waste foundry sand. The waste foundry sand was bioleached using Aspergillus sp. The treated and untreated sand was later used for growing Coriander sapling under controlled conditions and observed for the metal absorption after growth. Our observations provide a supportive document on bioleaching of WFS by Aspergillus sp. was adequate in the growth of herbal plant Coriandrum sativum.

Analysis of machining parameters of aluminum power mixed EDM process
Scientifically emerging industries like automotive, defense, aerospace, electronics, nuclear power, metallic molds and dies require materials of high strength, high-temperature resistant alloys like carbides, super alloys, haste-alloys etc. Manufacturers strive hard to produce these components at lower cost and of esteem quality as they have a direct impact on the profit earned by the firm. Hence, the productivity can be improved by increasing the material removal rate (or) by reducing the machining time of the product. Addition of a fine conductive powder to the dielectric fluid decreases its insulating strength and consequently increases the inter-electrode space causing an easy removal of the debris.The process variables of PMEDM play a considerable role in material removal mechanism. Performance of the PMEDM process depends upon characteristics like powder type, concentration, particle size, electrode area and workpiece constituents. As a result, the process becomes more stable, thereby, improving the material removal rate (MRR) and surface finish. Moreover, the surface develops high resistance to corrosion and abrasion. In this study, we have chosen the OHNS (Oil Hardened Non-Shrinking) die steel as workpiece material. A copper electrode and brass electrode with a diameter of 10 mm were used to cut the workpiece in EDM. Commercial kerosene has been chosen as the dielectric fluid. The consequence of the Machining parameters such as Pulse ON time, Pulse OFF time and current over the Machining time and Surface Roughness has been analyzed. The interaction study is made by Response Surface Methodology.

Interactive physiotherapy
Technological progress made in the field of computer science with the passage of time has become ever-present in the lives of the majority of people. This form of progress can also be used in medical rehabilitation as an interactive game based physiotherapy. Physical therapy is always a big part of rehabilitation, but as time goes by, patients tend to get tired and demotivated due to repetitive and tedious exercises. It’s hard and time-consuming to book an appointment with a good physiotherapist. So, an interactive motion detection system with the help of Kinect can be a boon to this problem. It works as a mirror because it helps patients in the perception of moments offering a visual feedback. The use of interactive physiotherapy makes the treatment more encouraging, stimulating the human senses (mainly body movements)

A comprehensive view of encryption and automatic file updating system
Lately, the information that can be stored and analyzed in the petabyte scale datasets also known as Big Data has proved to be immensely utilitarian due to its innumerable applications such as analysis of user’s choices which can be used in the manipulation of options provided to a user by various firms and organizations. This is intended for the benefit of the user can be highly beneficial and fructuous. This Big Data is stored in storage places called as Cloud that have other kinds of data directly provided by users stored as well. Applications of these data directly provided by users usually entail storing large data chunks in certain designated locations by the users so that the user does not have to worry about managing data storages for the same. These applications have led to opening up of a whole new plethora of possibilities, trends, and engagements. Unfortunately, not all of these are legit and we can see malpractices cropping up every day due to manipulation of user’s personal data for odious uses and ill-intentions. That being said, one must not undermine the cumulative storage size required for storing these magnanimous data. [Problems]: This means the major concerns for data storage in Cloud today are two. The first one is managing large data storage locations. The second one is the safety of stored data from Machiavellian sources that unceasingly try to get hold of intricate data for malicious purposes. [Solution]: Therefore this research aims at finding a way out of these prevalent problems. This is achieved by aiming at the two major problems. The first one is dealt with using distributed file storage system which can be employed by an organization to store intricate personal data in their own computing systems. This would enable them the assurance of no data leakage by a foreign data storage firm that would have been managing their data on its own cloud. Using this distributed file system would also hold the organization accountable for any data breaches and hence the security of data could be managed in a better way. The second problem of security against malicious data intrusions is dealt with using encryption and decryption techniques while storing and retrieving data. The encryption-decryption technique utilized in this research is RSA. [Result]: By performing the aforementioned steps, the two major concerns that come with storing personal data on the cloud can be handled efficiently.
