This paper deals with the latest technology called the sixth sense. It's a wearable interface that augments the physical world around us with the digital information. It's just born concept which allows user to connect with the internet seamlessly. Without use of keyboard, mouse we can see videos access, change, move data simply. But this concept bottle necks lead to modification of the same by using commands instead of gestures. Speech IC is used as a database for commands which will be initially trained for storage. It performs the corresponding commands accessing the operation from the mobile device connected to it and action is projected using a projector over any surface. It's more possibly to be implemented in future because of its cost constraints.Have you ever thought of doing your daily works digitally? What happens if the digital world is merged into the real world? For example, imagine taking a picture with your hands. Or imagine dialing a phone with the palm of your hands. A web cam pinched in a piece of paper becomes an I-pad. Wouldn’t that be interesting? This is made possible by a technique known as ‘Gestural interface’. It is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms interface. Using this technique, a new technology known as the ‘Sixth sense technology’ has been developed.

SQL injection is a code injection , used to attack the data-driven applications, in which malicious SQL statements are added into an entry field for execution (e.g. to dump the database contents to the attacker). SQL injection should exploit a security vulnerability in an application's software, for instance, when user input is incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and suddenly executed. SQL injection is mainly known as an attack vector for websites but it can be used to attack any type of SQL database.

A video encoder is software that enables compression of digital video; the format of the compressed data adheres to a video compression specification. The compression is usually lossy. Historically, video was stored as an analog signal on magnetic tape. Around the time when the compact disc entered the market as a digital-format replacement for analog audio, it became feasible to also begin storing and using video in digital form and a variety of such technologies began to emerge. Audio and video call for customized methods of compression. Engineers and mathematicians have tried a number of solutions for tackling this problem. There is a complex relationship between the video quality, the quantity of the data needed to represent it (also known as the bit rate), the complexity of the encoding and decoding algorithms, robustness to data losses and errors, ease of editing, random access, and end-to-end delay.

The Cloud Computing is one of the emerging modern technologies that need to meet the emerging business needs for agility, flexibility, cost reduction and time-to-value. The developments in cloud computing paradigm necessitate faster and efficient performance evaluation of cloud computing servers. The advanced modeling of Cloud servers are not feasible one due to nature of cloud servers and diversity of user requests.This issue necessitates calculating performance of cloud servers and should be capable of handling several millions of requests in few seconds. It is so possible through the specialized computing facility called Virtualization and even with it, very hard to serve plenty of requests continuously or simultaneously without delay or collision. We proposed a new mechanism to overcome these performance problems and to aim for optimize their performance; we can achieve this goal with help of queuing theory.To tackle the problem of optimizing the performance of cloud servers, we model the cloud servers with multitenant architecture as an M/G/m/m + r queuing system with single task arrivals and a task buffer of finite capacity. In this model focusing on input buffer size, number of servers, mean number of request, responseand etcas metrics for performance. The proposed algorithm named approximate Analytical model, and is equivalent to the combination of Transformation based Analytical Model & an Approximate Markov Chain Model with supporting calculations works out to bring the optimized performance evaluation of cloud servers.

In Wireless Sensor Network (WSNs), gather the data by using mobile sinks has become popular. Reduce the number of messages which is used for sink location broadcasting, efficient energy data forwarding, become accustomed to unknown earthly changes are achieved by a protocol which is projected by a SinkTrail. The forecast of mobile sinks’ location are done by using logical coordinate system. When sensor nodes don’t have any data to send, at that time they switch to sleep mode to save the energy and to increase the network lifetime. And due to this reason there is a chance of the involvement of nodes that are in sleeping state between the path sources to the mobile sink which is selected by the SinkTrail protocol. Before become the fully functional and process the information, these sleeping nodes can drop the some information. Due to this reason, it is vital to wake-up the sleeping nodes on the path earlier than the sender can start transferring of sensed data. In this paper, on-demand wake-up scheduling algorithm is projected which is used to activates sleeping node on the path before data delivery. Here, in this work the multi-hop communication in WSN also considers. By incorporating wake-up scheduling algorithm to perk up the dependability and improve the performance of on-demand data forwarding extends the SinkTrail solution in our work. This projected algorithm improves the quality of service of the network by dishonesty of data or reducing the loss due to sleeping nodes. The efficiency and the effectiveness projected solution are proved by the evaluation results.

The salinity tolerance of four rice genotypes, at germination and early seedling stages was evaluated using six salinity levels of Nacl and Kcl. Data regarding final germination percentage, germination energy percentage, plumule and radical length and seedling dry weight were recorded. Salinity decreased the various parameters studied in different varieties and the degree of inhibition increased with increasing salinity level. At 20 dS m-1 salinity level, germination was completely inhibited for all four genotypes. Using seedling dry matter reduction as the criteria, the genotypes were categorized as tolerant (T), moderately tolerant (MT), moderately susceptible (MS) or susceptible (S). Jhelum showed greater dry matter accumulation and better salt tolerance during germination and early seedling growth compared to other three genotypes. The results suggest that Jhelum can be recommended to be cultivated on the slightly saline soils.

This paper attempts to examine the way as how Genetic Algorithm (GA) can be employed in finding the best solution amongst a given number of possible solutions, the basic principle being extracted from the evolution and adaptation of organisms. The thought of Genetic Algorithm primarily originates from the perception of Charles Darwin who thought that combination of selection and variation is what that makes evolution of organisms perfectly adaptable to the environment. As generations pass, better adaptable organisms are born and the system slowly reaches to a most favorable point. GA makes use of this principle and eventually converges to the best “optimal� solution amongst a set of given solutions. In searching for a solution, a population of candidate is generated, evaluated, selected, and reproduced with modification to produce the candidate population until no further improvement can be made or after certain numbers of generations have generations have evolved, as according to the need of the problem.

Mobile Ad Hoc Networks (MANET) are autonomous and decentralized wireless systems. MANETs consist of mobile nodes that are free in moving in and out in the network. The main classes of routing protocols are Proactive, Reactive and Hybrid.[1] A Reactive (on-demand) routing strategy is a popular routing category for wireless ad hoc routing. In black hole attack, a malicious node sends the route reply message(RREQ) to the source node in order to advertise itself for having the shortest path to the destination node. we propose a new route maintenance algorithm to avoid black hole attacks. We propose this algorithm based on AODV (Ad-hoc On-demand Distance Vector routing protocol).

This paper described a hybrid methodology that can be deployed in the development of an intelligent critical sensitive system. To obtain this methodology, we interfaced the internationally accepted Structured System Analysis and Design Methodology (SSADM) and the Fuzzy Based Design paradigm. The SSADM was deployed for the systems study and preliminary design while the Fuzzy Based Design Methodology was deployed as the paradigm for an alternative design applied in developing both linear and non-linear systems for embedded control. The resulting methodology was successfully deployed to implement an intelligent traffic control system for a typical ‘+’ in an Eastern Nigerian city. The work demonstrated that embedded systems required a hybrid methodology because in addition to the specialized design paradigm, there would be a need for a detailed study of the systems current operating environments.

Captcha is a popular real user detection or autobot/robot rejection technique used in websites for Desktops. Captcha is also in use in some of the mobile websites. Captcha are difficult to read on the smartphone and portable computer screens. Users stuck in zooming in/zooming out while reading and filling the captcha and other required fields. Old aged users feel it more difficult to view and type the catpcha. So, there is a strong need of image based easy captcha-like technique to detect the real users and to avoid the autobot/robot tools, which are used to exploit the website databases. In this research we have proposed a visual/graphical alternate to captcha. In this research, we are proposing the development of a new captcha-like technique which will facilitate the user to enter a graphical captcha instead of text based captcha. Users will see a full image and a chunk from the image (sub-image). User will have to tap on the image area, which matches the chunk (sub-image). Further, the system will crop the image to that particular area in some particular size, which will be then forwarded to the server for the real-user authentication. Server side will match the chunk with the cropped image (which is a user input). If chunk is matched with the cropped image, the user will be marked a real user, otherwise a new captcha-like will be sent to the user for re-authentication. If user will fail for a fixed number of times, the server-side will mark the user as a autobot and will block the user for some time.

Energy efficiency is an important concern in wireless mobile ad hoc networks, because the mobile nodes in ad hoc networks communicate without an aid of an infrastructure on limited battery capacity. Here a new routing algorithm called Position Based Hybrid Routing (PBHRA) describes effective use of bandwidth and extend the battery life of the mobile nodes. This is done, by reducing the computational time in the proposed algorithm. The mobile nodes in MANETS do not have a centralized Administration. Hence in PBHRA, the central node for controlling the route determination acts as Master node which directs and controls the other nodes. The performance evaluation of the algorithm

The brain and spinal column make up the central nervous system (CNS), where all vital functions of the body are controlled. When tumors arise in the central nervous system, they are especially problematic because a persons thought processes and movements can be affected. These tumors can also be difficult to treat because the tissues surrounding a tumor that may be affected by surgery or radiation may play a vital role in functioning. There are two broad types of cancers occurring within this system. primary tumors originate in the central nervous system, whereas secondary tumors migrate from cancers located elsewhere in the body, such as breast cancers. Secondary, or metastatic, brain tumors, are more common than primary brain cancers. This section focuses on primary stages on brain cancer.

Our project aim is to build a handheld device that would help deaf and dumb people to communicate with others in every day spoken language such as English. Deaf and dumb often communicate via sign language, a kind of representation of words through hand and finger positions. But it has got serious limitations because it is not easy to understand by a normal listener on the opposite and to make things worse, not many in the world know sign language at all. Also, it is difficult to represent all the words of a plain language like English into a sign language symbol. Even if there is one, then learning and using them would be tough and cumbersome. In this paper, we will focus on the history of communication technologies that have given better access to the world for those with sensory disabilities. The areas that will be covered are communication technologies that improve or augment hearing and vision, and technologies that support alternatives strategies to communication without hearing and/or vision.
