Soil contamination by heavy metals is a major problem at many contaminated sites now a day. According to EPA’s list of priority pollutants cadmium, chromium, copper, lead, mercury, nickel, and zinc are the most hazardous heavy metals found at many soil contaminated sites. Many techniques are employed for the decontamination of soils. This consists of various physiochemical as well as biological methods. Among these process soil washing is a physiochemical method, which has a very high efficiency for heavy metal removal from contaminated soils. It is a simple, ex situ remediation technology. In this process by the addition of washing water, heavy metals can be transferred from the degraded sediment to wash solution. This process can be enhanced by addition of acid washing, chelating agents or surfactants. Particle size always plays an important role in the removal of heavy metals. In this research paper an attempt has made to soil washing technology for removal of Pb and Cr from contaminated soil with the help of different combination of EDTA and DI water cycle. Another attempt has also made to find out the effect of particle size i.e. soil, silt and clay on the soil washing.

Cloud computing and Infrastructure-as-a-Service (IaaS) are emerging and promising technologies, however their faster-pased adoption is hampered by data security concerns. At the same time, Trusted Computing (TC) is experiencing an increasing interest and revived interest as a security mechanism for IaaS. In this paper we present a protocol and We address the lack of an implementable mechanism to to ensure the launch of a virtual machine (VM) instance on a trusted remote compute host. Relying on Trusted Platform Module operations such as binding and sealing to provide integrity guarantees for clients that require a trusted VM launch, we have designed a trusted launch protocol for VM instances and images in public IaaS environments. We also present a proof-of-concept implementation of the protocol based on OpenStack, an open-source IaaS platform. The results provide a basis for the use of TC mechanisms within IaaS platforms and pave the way for a wider applicability of TC to IaaS security.

In the history of internal combustion engine development, hydrogen has been considered at several phases as a substitute of hydrocarbon-based fuels. Starting from the 70’s, there have been several attempts to convert engines for hydrogen operation. Together with the development in gas injector technology it has become possible to control precisely the injection of hydrogen for safe operation. Here we are using stainless steel plate as electrode in the electrolytic cell, the electrolyte being water and NACL salt. The electrolytic cell we used is a 12V battery case made of plastic. The cross sectional layers are cut such that the stainless steel plate fix in the battery case. The plates are separated by very small distance and the plates are given parallel holes for electron flow to be uniform. The power source to the kit is provided by a 12V and 9Ams battery. We used a transparent tube to supply the hydrogen produced in the kit to the air hose tube of our motor cycle. In order to keep the battery charged we used two 6 Amp diode to power the battery while running. There is a separate switch to power the kit and to protect the battery from getting drained. The stainless steel plates are of 50cm length, 25cm height, 2 millimeter thickness. The battery case can hold up to 5 liters of electrolyte. The use of hydrogen with petrol to power the vehicle has resulted in increase in vehicle mileage, accelerating speed with most important task of reduction in exhaust emission.

The present study deals with the force and stress distribution within the anteromedial (AM) and posterolateral (PL) bundles of the anterior cruciate ligament (ACL) in response to an anterior tibial load with the knee at full extension was calculated using a validated three dimensional finite element model (FEM) of a human ACL. The interaction between the AM and PL bundles, as well as the contact and friction caused by the ACL wrapping around the bone during knee motion, were included in the model. The AM and PL bundles of the ACL were simulated as incompressible homogeneous and isotropic hyperelastic materials. The validated FEM was then used to calculate the force and stress distribution within the ACL under an anterior tibial load at full extension. The AM and PL bundles shared the force, and the stress distribution was non-uniform within both bundles with the highest stress localized near the femoral insertion site. The contact and friction caused by the ACL wrapping around the bone during knee motion played the role of transferring the force from the ACL to the bone, and had a direct effect on the force and stress distribution of the ACL. This validated model will enable the analysis of force and stress distribution in the ACL in response to more complex loading conditions and has the potential to help design improved surgical procedures following ACL injuries.

Sense amplifiers are extensively used in memory. Sense amplifiers are one of the most vital circuits in the periphery of CMOS memories. We know that memory is the heart of all digital systems. Today all worlds are demanding high speed and low power dissipation as well as small area. We know that speed and power dissipation of memory is overall depends upon the sense amplifier we used and their performance strongly affects both memory access time, and overall memory power dissipation. So it is important to design a good sense amplifier which performs well in both speed and power dissipation. In this dissertation, an implementation of a most efficient sense amplifier is done by comparing the best known sense amplifier in today. The dissertation focuses on design, simulation and performance analysis of sense amplifiers. In this thesis, current latch sense amplifier and body bias controlled current latch sense amplifier are designed and results compared. The result shows that the body bias controlled current latch sense amplifier is performing best. The result also shows a novel sense amplifier which consumes small power at same time its speed is faster than other sense amplifiers.

This work deals with the application of Computational Fluid Dynamics (CFD) for cyclone modeling on three-dimensional unstructured mesh using the Reynolds Stress turbulence model, a standard k-ε or a k-ω model and Large Eddy simulation. Large-eddy simulations (LES) is performed on the gas flow in a cyclone at Re = 280,000. Numerical analysis of flow characteristics and separation efficiency in a high-efficiency cyclone is carried out. The model is only estimated the cyclone's performance under the limited environments; it is difficult to obtain a general model for all the types of cyclones. The purpose of this study is to find out the flow characteristics and separation efficiency numerically using ANSYS Fluent software. The Reynolds stress model (RSM), standard k-ε model and Large Eddy simulations are used in this work to know the flow separation characteristics. The models represent the 3-D, time-dependent flow analysis. CFD velocity profiles, and pressure drops for all the time-dependent flows are compared and discussed. Some details of the flow in the relatively small region in the vicinity of the inlet have strong influence on the separation process is checked with the simulations. The cyclone flow field pattern is simulated and analyzed with the aid of velocity components and static pressure contour plots.

Grinding wheels are made of natural or synthetic abrasive minerals bonded together in a matrix to form a wheel. For manufacturers, grinding wheels provide an efficient way to shape and finish metals and other materials. Grinding wheels are the only way to create parts with precision dimensions and high-quality surface finishes. At this time, grinding wheels are used in almost every industry. Manufacturing of a grinding wheel consist of mixing abrasive grains, binders and bonding materials. Three important components, abrasive grains with binders and bonding materials, make up any grinding wheel. The, additives are mixed to create a wheel with the properties necessary to shape a particular material in the manner desired. Abrasive grains include the central part of any grinding wheel, and the toughness and friability of the grinding materials will significantly affect the behavior of a given wheel. In the next step the ingredient mix is poured into the mold and compressed by a hydraulic press. Most grinding wheels are manufactured by the compression method, in which a mixture of components is pressed into shape at room temperature. The wheel is then fired at 200 0C-1260 0C depending upon the type of the bond. The purposes of the firing are to melt the binder around the abrasives and to convert it to a form that will resist the heat and solvents encountered during grinding. Variety of furnaces is used to fire grinding wheels. After firing, wheels are moved to a finishing area, where holes are reamed to the specified size and the wheel circumference is made concentric with the center. Some work may be necessary to correct thickness or parallelism of wheel sides, or to make a special contour on the side or circumference of the wheel. Sometimes balancing of large wheels is necessary to reduce the vibration that will be generated when the wheel is spun on a grinding machine.

Data Mining can be defined as an activity that extracts some new nontrivial information contained in large databases. Traditional data mining techniques have focused largely on detecting the statistical correlations between the items that are more frequent in the transaction databases. Also termed as frequent itemsets mining, these techniques were based on the rationale that itemsets which appear more frequently must be of more importance to the user from the business perspective .In this paper we throw light upon an emerging area called Utility Mining which not only considers the frequency of the itemsets but also considers the utility associated with the itemsets. The term utility refers to the importance or the usefulness of the appearance of the itemset in transactions quantified in terms like profit , sales or any other user preferences. This paper presents a novel efficient algorithm FUFM (Fast Utility-Frequent Mining) which finds all utility-frequent itemsets within the given utility and support constraints threshold. It is faster and simpler than the original 2P-UF algorithm (2 Phase Utility-Frequent), as it is based on efficient methods for frequent itemset mining. Experimental evaluation on artificial datasets shown here, in contrast with 2P-UF, our algorithm can also be applied to mine large databases.

This paper involves the review of the Shadow Detection and Removal in still images. No prior information has been used such as background images etc. for finding the shadows. It is a very challenging issue for the computer vision system that shadows effect the perception of artificial intelligence based machines in appropriately detecting the particular object as shadows also picked by them and detected as false positive objects. Also in surveillance, it affects the proper tracking of humans such as at airports. We proposed a method to remove shadows which eliminates the shadow much better than existed methods. RGB space has been used of the images and some morphological operations also applied to get better results.

To fulfill the requirement for steel with higher strength while retaining its formability, advanced high strength steels (AHSS) was developed. Several authors worked on the first generation AHSS steels with Dual phase structure and successfully achieved high strengths as compared to conventional counter-parts but could not achieve good formability. Several authors worked to overcome this problem and substantially improved the ductility and strength by forming second generation AHSS. However, DP steels were not formed (in second generation). Second generation steels (included ASS, TWIP steels etc.) were dependent on expensive alloy additions and were not cost effective. Authors became successful in achieving good strength and ductility but because of alloying, the weldability suffered. Finally, a few authors have reported their work on third generation AHSS, where first generation dual phase steels have been modified through suitable alloy additions to improve formability, strength and toughness. Work has been reported where carbon has been reduced to improve weldability. There is extremely limited work has been done for production of dual phase multipurpose steels with controlled cooling.

Nowadays construction materials are increasingly evaluated by their ecological characteristics. Concrete recycling gains importance because it protects natural resources and eliminates the need for disposal by using the readily available concrete as an aggregate source for new concrete or other applications. The concrete in this paper is produced by utilizing alternative and recycled waste materials such as fly ash and recycled concrete aggregates to reduce energy consumption, environmental impact, and usage of natural resources. The inferior quality of recycled aggregate (RA) has restricted its use to low-grade applications such as roadwork sub-base and pavements, while its adoption for higher-grade concrete is rare because of the lower compressive strength and higher variability in mechanical performance of RA. A new concrete mixing method, two-stage mixing approach (TSMA), was advocated to improve the quality of RA concrete (RAC) by splitting the mixing process into two parts. In the current paper we will discuss two parameters on which the concrete made by TSMA has been tested for strength characteristics viz. compressive strength and flexural strength. These parametric properties are compared with the conventional concrete with the variation of percentage of recycled coarse aggregates(RCA) and fly ash.

A brain-computer interface (BCI), sometimes called a mind-machine interface (MMI), or sometimes called a direct neural interface (DNI), synthetic telepathy interface (STI) or a brain-machine interface (BMI), is a direct communication pathway between the brain and an external device. BCIs are often directed at assisting, augmenting, or repairing human cognitive or sensory-motor functions.Research on BCIs began in the 1970s at the University of California Los Angeles (UCLA) under a grant from the National Science Foundation, followed by a contract from DARPA.[1][2] The papers published after this research also mark the first appearance of the expression brain-computer interface in scientific literature.The field of BCI research and development has since focused primarily on neuroprosthetics applications that aim at restoring damaged hearing, sight and movement. Thanks to the remarkable cortical plasticity of the brain, signals from implanted prostheses can, after adaptation, be handled by the brain like natural sensor or effector channels.[3] Following years of animal experimentation, the first neuroprosthetic devices implanted in humans appeared in the mid-1990s.

Combustion phenomena related to Froude number and Stroukal number were investigated in diffusion flames under various gravity levels. The Froude number of the fuel was controlled by gravity level, diameter of the nozzle, and fluid flow rate. Theoretical analysis is presented to laneway flame length model based on dimensional analyses. Analysis results indicate that flame length relates to heat release rate, fire source diameter, combustible matter diffusivity, etc. Based on Similarity principle, the laneway fire experiment plant has been setup. And using a video camera, the data of the experiment is recorded. Experiment results indicate that flame length is directly proportional to heat release rate, fire source diameter and combustible matter diffusivity. And a semi-empirical formula on flame length has been got using the least-square program to fit the experimental data. The results are of importance for flame radiation calculation and fire risk analysis. Flame is an important parameter for any combustion process which is responsible for either the complete or incomplete combustion process. There are certain factors which influence the flame length and diameter such as fire source diameter or nozzle diameter, equivalence ratio, quality of fuel, heat release rate etc. Investigation of flame length and diameter is more relevance in the rational design of combustion chamber, be it for an internal engine or for a furnace. The flame represents the zone of combustion, its length is a measure of the intensity of combustion and therefore of heat release. So, this paper reviews about the flame behavior on the basis of flame length and diameter.
