There have been insurmountable obstacles for sharing instructions with disabled students but now they can be easily overcome by using the free programs TeamViewer in combination with Skype, Krut Computer Recorder and Zoomtext because they allow to transmit all instructional material in accessible format in real time from the lecture computer directly to the screen of the disabled student. Moreover, they allow for efficient one on one tutoring by allowing the visually impaired student to follow with Zoomtext without limiting the visual field of the online instructor. These programs can be used to extend computer lab hours and thus give more time to disabled students to complete their lab assignments. Logging remotely into the instructor's computer allows beaming lectures directly into the screen of visually impaired students. These programs can enhance online collaborations even for non disabled people and help to better integrate disabled people into an increasingly specialized and competitive workforce. © 2016 IEEE.

We work on the reconstruction scenario of pilgrim dark energy (PDE) in f(T,TG). In PDE model it is assumed that a repulsive force that is accelerating the Universe is phantom type with (wDE<-1) and it is so strong that prevents formation of the black hole. We construct the f(T,T G) models and correspondingly evaluate equation of state parameter for various choices of scale factor. Also, we assume polynomial form of f(T,TG) in terms of cosmic time and reconstruct H and wDE in this manner. Through discussion, it is concluded that PDE shows aggressive phantom-like behavior for s=-2 in f(T,TG) gravity. © 2014 Springer Science+Business Media Dordrecht.

In the present work, we study the consequences of considering a new family of single-field inflation models, called power-law plateau inflation, in the warm inflation framework. We consider the inflationary expansion is driven by a standard scalar field with a decay ratio Γ having a generic power-law dependence with the scalar field ϕ and the temperature of the thermal bath T given by Γ(ϕ,T)=CϕTaϕa-1. Assuming that our model evolves according to the strong dissipative regime, we study the background and perturbative dynamics, obtaining the most relevant inflationary observable as the scalar power spectrum, the scalar spectral index and its running and the tensor-to-scalar ratio. The free parameters characterizing our model are constrained by considering the essential condition for warm inflation, the conditions for the model evolves according to the strong dissipative regime and the 2015 Planck results through the ns–r plane. For completeness, we study the predictions in the ns–d ns/ d ln k plane. The model is consistent with a strong dissipative dynamics and predicts values for the tensor-to-scalar ratio and for the running of the scalar spectral index consistent with current bounds imposed by Planck and we conclude that the model is viable. © 2017, The Author(s).

Voice transmission over the internet is the fundamental requirement of every organization. As a result various technologies have been introduced for the reliable transmission of voice over internet. Voice over Internet Protocol (VoIP) has emerged as a need for improvement of quality for a voice call. In this paper real time implementations have been performed for the VOIP over MPLS (Multi-Protocol Label Switching) network that ensures the quality of services for voice and other traffics as well. On the basis of study and hands on experience we have made certain conclusions and recommendations for a better QoS. The results for these experiments are quiet encouraging for the VOIP in term of Mean Opinion Score, Packet loss, and delay. © 2017 IEEE.

We discuss the warm inflation in the presence of standard scalar field model and modified Chaplygin gas in brane-world scenario. We consider weak and strong dissipative regimes with generalized dissipative coefficient. We extract various inflationary parameters. For example, we analyze the behavior of different ratios (ratio of dissipative co-efficient and Hubble parameter Γ/3H, ratio of temperature and Hubble parameter T/H, scalar-to-tensor ratio r) with respect to spectral index ns for the weak and strong dissipative regimes through parametric plotting. It is found that T/H and Γ/3H satisfied the required conditions in both dissipative regimes. It is also noted that the spectral index (ns ) attain the range ns = 0:96+0.10 -0.10. It is remarked here that our results are consistence with observational data WMAP7, WMAP9, and recent Planck data. © 2017 Chinese Physical Society and IOP Publishing Ltd.

In this paper, we consider interacting pilgrim dark energy (Hubble horizon as an infrared cutoff) with cold dark matter in flat universe. We develop the equation of state parameter in this scenario which shows the consistency with pilgrim dark energy phenomenon. In this framework, we analyze the behavior of scalar field and corresponding scalar potentials (which describe the dynamics of the scalar fields) of various scalar field models, graphically. The dynamics of scalar fields and potentials indicate accelerated expansion of the universe which is consistent with the current observations. © 2015, Springer Science+Business Media Dordrecht.

Purpose: The purpose of this paper is to analyze the recent global situation on waste of electric and electronic equipment (WEEE) management and recommend policy directions for designing environmental strategies. Design/methodology/approach: Qualitative research approach is adopted to review studies on WEEE management in developed and developing countries. The focus is to critically consider the available options for its safe management. Findings: Approximately 40-50 million tons of WEEE is generated worldwide annually and most of it is dumped in the developing countries. WEEE is not a challenge to be faced by a single country as it has trans-boundary effects and ultimately the contamination reaches back to the developed countries with a lapse of time. Research limitations/implications: Data availability on WEEE generation and disposal is in initial stages. Practical implications: Developing countries in Asia and Africa do not have resources to handle WEEE. The unregulated and unsafe WEEE management practices in these countries let hazardous materials to disseminate into the marine life and global ecosystem. Originality/value: The paper recommends policy directions to deal with the emerging issue that may have globally far reaching consequences. © Emerald Group Publishing Limited.

Ontologies can be built on systems that can evolve continuously. Ontologies analysis and appraisal are performed for measuring the eminence of an ontology. Ontologies evaluation is used to automatically reveal conceivability problems. For evaluating dynamic ontologies in semantic web and to set the weights to the neurons, Classical Neural Network (CNN) has to face a number of challenges such as the absence of discrete algorithm, limited memory capacity, time-consuming training due to the declarative nature of ontologies. CNN cannot provide low-cost learning. In CNN, data is non-linear and hard to analyze. Recently, with the rapid development of technology, there are a lot of applications such as dynamic ontologies creation and evaluation require to low-slung learning cost. However, the computational power of CNN, is that it cannot provide low-slung learning cost. On the other hand, Quantum Neural Network (QNN) can be a good computational network instead of CNN approaches. In this paper, we present a new computational approach for dynamic ontologies evaluation to the Quantum Perceptron Neural Network (QPNN) can achieve low-slung learning cost. The proposed Quantum Neural Network can construct self-adaptive activation operators that have the capability to accomplish the learning process in a limited number of iterations and thereby, reduce the overall computational cost. The proposed approach is capable to construct its own set of activation operators to be applied widely in both quantum and classical applications to overcome the linearity limitation of classical perceptron. © 2015 IEEE.

The proposal of pilgrim dark energy is based on the speculation that phantom-like dark energy possesses enough resistive force to preclude the black hole formation in the later universe. We explore this phenomenon by assuming the generalized ghost version of pilgrim dark energy. We find that most of the values of the interacting (ξ 2) as well as pilgrim dark energy (u) parameters push the equation of state parameter towards phantom region. The squared speed of sound shows that this model remains stable in most of the cases of ξ 2 and u. We also develop ωΛ-ωΛ ′ plane and observe that this model corresponds to thawing as well as freezing regions. Finally, it is shown that the non-interacting and interacting generalized ghost versions of pilgrim dark energy correspond to ΛCDM limit on the statefinder plane. © 2014 Springer Science+Business Media Dordrecht.

Any reform in education leverages reform in teacher education. The National Accreditation Council for Teacher Education developed Standards for Accreditation of Teacher Education Programs including specific standards relating to Education for Sustainable Development (ESD). Data from 103 teacher education programs (TEPs) accredited during the first 2 years evidenced that TEPs in the earlier phases remained low on ESD while those accredited later were found to be better. Data and feedback also reveal that TEPs are working to meet the prerequisite ESD indicators—nonaccredited ones before submission for accreditation and the accredited ones for improved ratings. Thus, accreditation is effective in overall quality enhancement of TEPs and is helping them to adopt ESD concepts and practices. © 2015, Copyright © Taylor & Francis Group, LLC.
