Object tracking is one of the well-known topic in computer Vision sphere with challenging and problematic tasks that frames come with problems like overlapping, camera motion blur, changing object appearance, environmental variations and so on. Using OpenCV based CSRT (Channel and Spatial Reliability Tracking) tracker itself, without integration object detection part may face problems which mentioned above. To overcome that challenges we integrated deep learning based object detection with CSRT tracker and got better tracking results.

Conducting reputation management is very important for Internet of vehicles. However, most of the existing researches evaluate the effectiveness of their schemes with settled attacking behaviors in their simulation which cannot represent the scenarios in reality. In this paper, we propose to consider dynamical and diversity attacking strategies in the simulation of reputation management scheme evaluation. To that end, we apply evolutionary game theory to model the evolution process of malicious users’ attacking strategies, and discuss the methodology of the evaluation simulations. We further apply our evaluation method to a reputation management scheme with multiple utility functions, and discuss the evaluation results. The results indicate that our evaluation method is able to depict the evolving process of the dynamic attacking strategies in a vehicular network, and the final state of the simulation could be used to quantify the protection effectiveness of the reputation management scheme.

Aspect oriented programming (AOP) helps programmers for separating crosscutting concerns. All programming methodologies support split up and encapsulation of concerns. In object-oriented programming (OOP) crosscutting aspects are distributed among objects. It is hard to attain crosscutting in OOP as it is scattered in different objects. In AOP crosscutting concerns are addressed using one entity called aspect. This paper discusses varieties of existing slicing techniques of AOP. Also, we discuss a novel method to calculate dynamic slice of AOP. To represent AOP Aspect Oriented System Dependence Graph (AOSDG) is used. The complexity of this new approach is equal or improved as related to certain prevailing approaches.

We experimentally investigate a mechanical squeezed state realized in a parametrically-modulated membrane resonator embedded in an optical cavity. We demonstrate that a quantum characteristic of the squeezed dynamics can be revealed and quantified even in a moderately warm oscillator, through the analysis of motional sidebands. We provide a theoretical framework for quantitatively interpreting the observations and present an extended comparison with the experiment. A notable result is that the spectral shape of each motional sideband provides a clear signature of a quantum mechanical squeezed state without the necessity of absolute calibrations, in particular in the regime where residual fluctuations in the squeezed quadrature are reduced below the zero-point level.

Advancement in ubiquitous techniques and the need of wide coverage network march towards convergence of networks. Mobile cellular network (MCN) is the largest network which can be the master network for this purpose and Wireless sensor network (WSN) can converge with MCN to form a single platform. As the world is moving towards machine to machine communication possibilities where WSN plays the major role. Hence there is a need to study the performances of the MCN-WSN convergence network. In this paper we have proposed an analytical model to accept the request from both WSN and MCN part and acceptances rate use certain probability to enter into a process at mobile node using processing sharing (PS) scheduling. The service rate is reduced to half of it's original rate to satisfy the processor sharing simultaneously for both WSN and MCN part. The performance factors like utilization, throughput is calculated and the analysis is done using graphs in numerical section.

This Ubiquitous application of cell phones leads to an idea of using cell phones as a carrier of sensor data, which can create a larger network. This represents an idea of heterogeneous network such as cellular network and wireless sensor network to emerge as WSN-MCN convergence network. These mutually benefit both the network but the resource allocation that shares spectrum resources between cellular users and WSN user is critically challenging. We propose a reservation based resource sharing scheme that reserves a part of the spectrum for cellular users and rest part of the spectrum is dynamically allocated to users of both the network. An analytical model has been developed to determine various performance factors of the converged network in terms of channel allocation. The proposed model is compared with existing schemes and numerical results are presented in the form of graphs.

Anomaly detection is one approach in intrusion detection systems (IDSs) which aims at capturing any deviation from the profiles of normal network activities. However, it suffers from high false alarm rate since it has impediment to distinguish the boundaries between normal and attack profiles. In this paper, we propose an effective anomaly detection approach by hybridizing three techniques, i.e. particle swarm optimization (PSO), ant colony optimization (ACO), and genetic algorithm (GA) for feature selection and ensemble of four tree-based classifiers, i.e. random forest (RF), naive bayes tree (NBT), logistic model trees (LMT), and reduces error pruning tree (REPT) for classification. Proposed approach is implemented on NSL-KDD dataset and from the experimental result, it significantly outperforms the existing methods in terms of accuracy and false alarm rate.

Phenomenological models aiming to join gravity and quantum mechanics often predict effects that are potentially measurable in refined low-energy experiments. For instance, modified commutation relations between position and momentum, that accounts for a minimal scale length, yield a dynamics that can be codified in additional Hamiltonian terms. When applied to the paradigmatic case of a mechanical oscillator, such terms, at the lowest order in the deformation parameter, introduce a weak intrinsic nonlinearity and, consequently, deviations from the classical trajectory. This point of view has stimulated several experimental proposals and realizations, leading to meaningful upper limits to the deformation parameter. All such experiments are based on classical mechanical oscillators, i.e., excited from a thermal state. We remark indeed that decoherence, that plays a major role in distinguishing the classical from the quantum behavior of (macroscopic) systems, is not usually included in phenomenological quantum gravity models. However, it would not be surprising if peculiar features that are predicted by considering the joined roles of gravity and quantum physics should manifest themselves just on purely quantum objects. On the base of this consideration, we propose experiments aiming to observe possible quantum gravity effects on macroscopic mechanical oscillators that are preliminary prepared in a high purity state, and we report on the status of their realization.

Recent optomechanical experiments have observed nonclassical properties in macroscopic mechanical oscillators. A key indicator of such properties is the asymmetry in the strength of the motional sidebands produced in the probe electromagnetic field, which is originated by the noncommutativity between the oscillator ladder operators. Here we extend the analysis to a squeezed state of an oscillator embedded in an optical cavity, produced by the parametric effect originated by a suitable combination of optical fields. The motional sidebands assume a peculiar shape, related to the modified system dynamics, with asymmetric features revealing and quantifying the quantum component of the squeezed oscillator motion.
