Semi-quantum protocols that allow some of the users to remain classical are proposed for a large class of problems associated with secure communication and secure multiparty computation. Specifically, first-time semi-quantum protocols are proposed for key agreement, controlled deterministic secure communication and dialogue, and it is shown that the semi-quantum protocols for controlled deterministic secure communication and dialogue can be reduced to semi-quantum protocols for e-commerce and private comparison (socialist millionaire problem), respectively. Complementing with the earlier proposed semi-quantum schemes for key distribution, secret sharing and deterministic secure communication, set of schemes proposed here and subsequent discussions have established that almost every secure communication and computation tasks that can be performed using fully quantum protocols can also be performed in semi-quantum manner. Some of the proposed schemes are completely orthogonal-state-based, and thus, fundamentally different from the existing semi-quantum schemes that are conjugate coding-based. Security, efficiency and applicability of the proposed schemes have been discussed with appropriate importance.

In the present research, vibration and instability of orthotropic graphene sheet subjected to thermo-magnetic fields are investigated. Orthotropic visco-Pasternak foundation is considered to analyze the influences of orthotropy angle, damping coefficient, normal and shear modulus. New first-order shear deformation theory is utilized due to accuracy of its polynomial functions compared to other theories of plate. Motion equations are obtained by means of Hamilton’s principle and then solved analytically. Influences of various parameters such as small scale, magnetic field, orthotropic viscoelastic surrounding medium, thickness and aspect ratio of single layer graphene sheet on the vibration characteristics of nanoplate are discussed in detail. The results indicate that the stability of single layer graphene sheet is strongly dependent on applied magnetic field. Therefore, the mechanical behavior of single layer graphene sheet can be improved by applying magnetic field. The results of this investigation can...

Today the world is confronted with the twin crisis of fossil fuel depletion and stringent emission norms, because of the environmental awareness. The disposal and degradation of waste plastic is a major issue and scarcities of fuel were major focus area of the researchers. In this virtue the waste plastic fuel extraction makes more attention to the researchers. In this research work focused to find the performance of the waste plastic fuel and compared to diesel. The waste plastic fuel extract from thermal cracking method this process the polymer chains were breakdown into useful lower molecular weight compounds and it becomes plastic pyrolysis it can be utilized as a fuel. The properties of the waste plastic fuel is obtained by various testing process and which is analyze and compare with the fossil fuel diesel. It is found that almost it has similar properties to the diesel and almost all properties of the pyrolysis is closer to that of diesel. The characteristics of the pyrolysis were tested in the engine test bed. The pyrolysis / waste plastic fuel can be directly used in diesel engines over the entire load spectrum smoothly without any major modification. The performance of the waste plastic fuel / pyrolysis is evidenced that it is one of the best alternative fuel as well as the waste plastic can be converted into a useful fuel

Efficient Video Watermarking Technique for Quality Loss of Data

Objectives: The system aims at developing an intelligent video surveillance system which analyses the behavior of moving object and classifies it as standing, walking (normal behavior) and bending (abnormal behavior). The proposed system is also capable of detecting the persons moving into the restricted region providing the user with an ease to select the area of its own choice, thereby eliminating the problem of static region of interest. Methods/Statistical Analysis: In this paper we have detected the moving objects and tracked them using Kalman Filter on the basis of id assigned to each moving object. The direction of the moving object is labeled as right, left, up and down. The experiments are conducted in the corridors and pathways at Lovely Professional University on various persons with different heights. Neural network is used to validate our work and helps us in setting an experimental threshold which decides when the person bends or walks. This eliminates the need of any special detector which estimates the human pose, thereby reducing the cost. The neural network produces an efficiency above 95% which is quite promising. The implemented system follows a new approach of eradicating the problem of static region of interest and helps us to generate an alert when a person enters into an illegal entry zone. Findings: The objective of the proposed work is to turn the passive cameras into active cameras. The system finds out the direction of the moving object with an accuracy lying between 86.9% and 100%. The existing systems deploy special detectors for pose estimation making the system very costly. The implemented system eradicates the need of such detectors. Neural network validates the abnormal bending behavior producing an efficiency above 95%. The proposed approach eliminates the problem of static region by allowing the user to define its own region of interest before the process starts. This region of interest is regarded as restricted region. When the person enters into the restricted region, the system generates an alert and marks it as illegal entry. This will reduce the time of the humans to monitor every single camera installed in the campus as the system will generate an alert in case of an illegal entry which is regarded as an abnormal event. There are three events in the dataset for illegal entry and the system detects all the three events correctly. We can also track the trajectory of every individual which can be useful if any mischievous activity is performed by that individual. Application/Improvements: With intelligent and automated systems, performance can be increased and cost can be reduced. The manpower can be reduced, thus increasing accuracy. The implemented system has its shortcomings as if it leaves the frame and enters again, the system will assign it a new id. The accuracy of calculating the direction can be improved.

In next generation wireless system such as Long Term Evolution (LTE) and Worldwide Interoperability Microwave Access (WIMAX) the major issue is to maintain the quality of service of a network. User required always best connected services anytime and anywhere. Due to increase in number of user on particular network, load is increased on a network. Due to high load handover is required but in many situations unnecessary handoff and handoff failure is initiated, which lags the performance of a network. To overcome this problem we have used RSS vertical handover decision method with some additional parameters to improve the performance in 4G heterogeneous networks.

Enhanced VHD Making Algorithm for 4G Heterogeneous Networks

Partial transmitted sequence (PTS) is the most important technique for the minimization of problem peak to average power ratio (PAPR) found in multicarrier system i.e., Orthogonal Frequency Division Multiplexing (OFDM). But PTS scheme undergo a very difficult and complex process of designing random phase sequences which are used for optimization of subblocks of data stream in time domain after applying Inverse Fast Fourier Transform (IFFT) so that the problem PAPR can be minimized. Hence in this paper we are proposing a technique in which we have used hadamard matrix for the optimization of sub-blocks of data stream in time domain after IFFT along with discrete cosine transform. So this proposed technique drastically reduced the complexity of designing phase sequence and help in recovering the same information back at the receiver side with the help of index of individual rows of hadamard matrix. Simulation results are presented under multiple sub carriers (N)=64,128 and 256, classic frequency domain partition partial transmitted sequence(CFDP-PTS)=3 and 4 shows a significant gain (dB)of around 3.8 and 1.4 in comparison of conventional OFDM system and traditional PTS technique respectively under N=128 and CFDP=4.
