 Abstract

According to the World Health Organisation report on disability, currently about 15% of world population lives with some type of disability out of which 2-4 % people experience significant difficulties in their day to day activities .There are cases of patients using wheelchair are not only limited to paralysed people but also blind ,physically handicapped and people having neuromuscular and spinal cord issues . Many of them uses electrically powered wheelchairs (PWC) that are the most helpful tool allowing individuals to complete daily tasks with greater independence and community environments. We provide solution for them by introducing Tongue Drive System (TDS). This system comprises PIC microcontroller and uses current continuity principle. According to movement of tongue, wheelchair will move in respective direction. Also IR sensor is provided which will help to detect obstacle present in the path..

 Abstract

In this paper we have presented a model to control robotic arm through human gestures using accelerometer. A three axis accelerometer is mounted on human hand in order to perform the action of robotic arm according to the action of human hand. Accelerometer is connected to the LPC2148 Microcontroller which is programmed to take analog readings from accelerometer and transmit them using Bluetooth to the receiving unit at robotic arm. Movements of the robotic arm are achieved through Servo-Motor are a type of electromechanical actuators that do not rotate continuously like DC/AC or stepper motors; rather, they are used to position and hold some object.They are used where continuous rotation is not required so they are not used to drive wheels (unless a servo is modified). The arm is also equipped with a gripper to facilitate the pick and drop facility.The main aim is to control the robotic arm using human gestures wirelessly with smooth movement over a range.

 Abstract

The aim is to study and modify car body by keeping concepts and phenomena of automotive aerodynamics in consideration. In first phase, detail study of aerodynamic behavior of a car segment by considering drag coefficient, frontal pressure, rear vacuum and down-force. To measure drag coefficient in particular and observing airflow around the body numerical and CFD analysis is to be used. At the same time to decrease vehicle's resistance and to increase down-force, a comparative numerical analysis is to be performed. There are two means of measuring the drag, the first is by simulating the air flow via computational fluid dynamics (CFD) suite, and the second is by using wind tunnel experiment. For practical analysis approach, wind tunnel set up can be used. As a result of this project we will be able to get a perfect aerodynamic car design with reduced drag-force, higher efficiency, better performance and less fuel consumption.

 Abstract

The present paper investigates the amalgamation of various cultures, ethnicity, and generations collaborating and creating a distinct culture of their own. The shadow lines creates a platform for the intermixing of cultures and ethnicity across borders. Amitav Ghosh illustrates the possibility of a multicultural oriented society where every individual has a recognized identity. The borders remain as a subsidiary concern of a particular person. In the novel, Tridib is portrayed as a philosophical person who is fascinated by the love of a person across borders. Ila also represents a cross-cultural relationship with Nick Price irrespective of their ethnicity which justifies the multiculturality in the novel. This paper further explores the different ethnic or national cultures across borders in the postcolonial era. The existence of different cultural identity in the contemporary period produced a space of their self. A cosmopolitan perspective can be studied into the characters of The Shadow Lines reflecting the unprejudiced contemplation of homogenous society.

 Abstract

Common objective of network traffic engineering is to minimize the maximum link utilization in network in order to accommodate more traffic and reduce the chance of congestion. TE plays a critical role in determining the performances and reliability of a network. Major challenge in Traffic engineering is how to cope with unpredictable changes in traffic demand. Traffic engineering (TE) is an important network application, which studies measurement and management of network traffic, and designs reasonable routing mechanisms to guide network traffic to improve utilization of network resources, and better meet requirements of the network quality of service (QoS).

 Abstract

The internet connects almost everything and is accessible by almost anywhere in the world. However, traditional IP networks are complex and very hard to manage. It is difficult to reconfigure it to respond to changes made. Also, managing the network infrastructure has become a complicated and time-consuming task. Recently, Software Defined Networking (SDN) has gained the attention of researchers due to the ease of centralized control and programmability of the network. SDN is characterized by its two distinguished features, including decoupling the control plane from the data plane and providing programmability for network application development. This paper first presents a generally accepted definition of SDN with the potential need for SDN. This paper provides a snapshot of the related work done by various researchers. Finally, we conclude this survey paper with some open research challenges

 Abstract

Botnets are the preeminent normal vehicle of digital criminal action. They're utilized for spamming, phishing, dissent of-benefit assaults, animal power breaking, taking non-open information, and digital fighting. A botnet (additionally alluded to as a zombie armed force) might be a scope of net PCs that, however their mortgage holders are ignorant of it, are got twist of to forward transmissions (counting spam or infections) to elective PCs on the web. Amid this paper, we tend to propose a two-organize approach for botnet identification. The essential stage distinguishes and gathers arrange irregularities that are identified with the nearness of a botnet while the second stage recognizes the bots by breaking down these peculiarities. Our approach abuses the ensuing 2 perceptions: (1) botmasters or assault targets are less demanding to discover because of the give with a few elective hubs, and (2) the exercises of contaminated machines are a considerable measure of correlative with each other than those of customary machines

 Abstract

In cloud, an effective way to ensure security is using Data Access Control. But, data access control becomes a very challenging issue in cloud storage systems due to untrusted cloud servers and data outsourcing. To overcome this problem multi-authority Attribute Based Encryption is employed. In this different sets of attributes along with the corresponding decryption keys are issued to users by the attribute authorities. Ciphertext Policy Attribute Based Encryption (CP-ABE) is a promising cryptographic technique based on these attributes. A user is able to decrypt a ciphertext if and only if his attributes satisfy the ciphertext access structure in which each user is associated with a set of attributes and the data is encrypted using access structures. However, attribute revocation becomes cumbersome for this scheme. The proposed solution enables the multi-authority to revoke user attributes with minimal effort. By uniquely integrating the technique of proxy re-encryption and CP-ABE, attributes can be revoked with minimal effort. This enables the authority to delegate the most laborious tasks to proxy servers.

ABSTRACT Image can be improved using different image enhancement techniques. It includes different types of operations like image segmentation, Clustering, smoothing, etc. Basically in the process of Image segmentation features having homogenous characteristics are identified. The Input for the system is color image. The image gets converted into horizontal and vertical shape histogram. Then cluster formation is done using hill climbing technique and k means clustering. K Means clustering consider colour intensity as criteria. Sequential probability ratio test checks similar characteristics between different regions. Merging of these regions follows dynamic region merging algorithm. Depending on similar properties partitions are merged. The output is enhanced segmented image. Nearest neighbour graph technique is helpful to speed up the above process. This improved image is useful in the field of medical as well as security purpose
