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 study the reconstruction scenario of modified gravity with a dynamical dark-energy model filling the universe. In this context, we consider the Modified f(R) Horava-Lifshitz Gravity with a new agegraphic dark-energy model using the power-law form of the scale factor. We construct a modified f(R) Horava-Lifshitz model and check its behavior along its argument. To discuss the accelerated expansion of the universe, some cosmological parameters are discussed as well. The equation-of-state parameter represents the phantom behavior of the universe as well as the statefinder diagnostic pair gives the phantom and quintessence regions. Also, the stability analysis is carried out through squared speed of sound which points out the stable modified f(R) Horava-Lifshitz model except in a small time interval. © Società Italiana di Fisica/Springer-Verlag 2014.

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 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.

Let L be a distributive lattice and R(L) the associated Hibi ring. We compute reg R(L) when L is a planar lattice and give bounds for reg R(L) when L is nonplanar, in terms of the combinatorial data of L. As a consequence, we characterize the distributive lattices L for which the associated Hibi ring has a linear resolution.

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.

This paper explains our antenna design for Near Field Communication. A lot of NFC tags are available in the market that can be used for different purposes. However most of these tags are vendor made and are normally designed in a way that they do not fit in for all the situations. Most of these tags are circular or square in shape with a fixed diameter and cannot be used in wearable items like watches, wrist bands, and rings etc. To overcome this difficulty we have developed our own custom antenna for passive NFC tag that is well suited for wearable items like wrist bands etc. © VDE VERLAG GMBH, Berlin, Offenbach, Germany.
