Active thermographic studies using non stationary coded thermal wave imaging methods facilitate deeper sub surface analysis with better depth resolution even with relatively low peak powers. They exhibit a variation in detection capability due to their diversity in shape and frequency content etc., In order to compare the ability of these schemes in spite of their diversity, a common feature based...
Virtualizing the educational contents and resources as well as conceptual entities would form VOs and CVOs for WoO paltform. which provides dynamicity and intelligence through composition and collaboration for self-directed learning in smart learning environment. Semantic ontology in WoO platform supports dynamic composition and collaboration among objects, VO and CVO, for intelligent learning model...
This paper tackles the problem of categorizing materials and textures by exploiting the second order statistics. To this end, we introduce the Extrinsic Vector of Locally Aggregated Descriptors (E-VLAD), a method to combine local and structured descriptors into a unified vector representation where each local descriptor is a Covariance Descriptor (CovD). In doing so, we make use of an accelerated...
This paper reports on some salient characteristics of how a large (21-foot wide) whiteboard wall mediates and facilitates the work of a software development team. While most research on whiteboards report on their use in design conversations, our data show this large whiteboard wall fulfilling 59 different uses over a 17 month period. This paper describes this whiteboard wall, categorizes the uses,...
This paper presents an automatic algorithm which generates depth map for 2D to 3D conversion. The depth map is generated by fusing global depth gradient and local depth refinement. First, the proposed algorithm judges the scene type of the input image. Then, it generates global depth gradient of the image according to its scene type. At last, local depth refinement is implemented by using warm/cool...
CAM systems are most widespread way to create cnc programs. Possibility of optimization, simulation of machining, shorter lead time, and flexibility are biggest benefits. Some of most used CAM systems are GibbsCam, PowerMill, AlphaCam, Surfcam, and Edgecam. Next article shows making of NC program in Edgecam. Edgecam was chosen because is user friendly and simple programs can be created without deeper...
This paper presents the comparison of the features of three dissimilar feeding methods namely co-axial probe, microstrip line and co-planer feeding for a thermally stable resonator antenna (TSRA). First, nanoparticles have been developed by using proper synthesis process and then mixed in accordance with their temperature coefficients such as to achieve thermal stability. The Nicholson-Ross-Weir conversion...
Etextbooks offer the potential to change the way faculty teach and students learn. One approach to providing etextbooks enables faculty to custom tailor traditional "flat" paper textbooks from major publishers by embedding videos and annotating them with comments. We conducted a lab study in which participants read a chapter in a computer networking book either in paper form, or using an...
In the IS discipline, the formulation of design principles is an important vehicle to convey design knowledge that contributes beyond instantiations applicable in a limited context of use. However, their formulation still varies in terms of orientation, clarity, and precision. In this paper, we focus on the design of artifacts that are oriented towards human use, and we identify and analyze three...
IT systems are, without a doubt, fundamental to almost all facets of modern life, including government operations, commerce and manufacturing, financial systems, education, communications, energy production and distribution, and transportation. However, given the global connectedness of such systems, they are under constant attack from a variety of actors ranging from automated malware and so-called...
Rogue websites support their operations through advertising, where advertising networks facilitate the placement of advertising banners paid for by advertisers who seek the most "relevant" eyeballs. While mainstream advertisers risk harm to their brands by being associated with illicit activities on the internet, they also risk harms to users through the co-location of ads for high-risk...
With the widespread coverage of the Internet, e-learning environments have greatly advanced. Students have increasing opportunities to access and interact both with course materials and with classmates. However, the functionalities of e-learning systems nowadays may not satisfy students across the full range of courses, especially computer software courses. The study makes use of the social networking...
This paper proposes an education assistive technology system based on a graphic haptic electronic board for improving the effects of education for the visually impaired in a special education environment for both low-vision and blind students. The system comprises of authoring and teaching SW for educators, viewer SW for students with low vision, and graphic haptic electronic board HW for blind students...
In the present EEG coherence study, we investigate the brain activation patterns and resource allocation strategies of high-intelligent individuals as compared to low-intelligent individuals while they solve linguistic problems with two levels of complexity. Results of our study supports both efficiency and resource hypothesis. Our findings suggest that high intelligent individuals allocate fewer...
Media coverage and public perception of topics such as child labor, exploitation of workers, and ecological malpractice have risen considerably over the last years. A rising number of executives therefore consider sustainability issues both in their companies and in companies' supply chains. However, a holistic approach towards sustainability requires management control (also referred to as management...
In this paper, we present a method for physics-based dynamic deformation simulation of 3D object. In interactive virtual deformation simulation, there are many common linear and non-linear elasticity models for various deformable situations. We discuss constitutive models of common materials and analyze their differences. On account of their homogeneous and isotropic material properties, these models...
Quantum dots (QDs) backlight brings several advantages to LCDs, including wider color gamut, higher light efficiency, enhanced ambient contrast ratio, and over 100X smaller color shift. The prime time for QD-enhanced LCDs is around the corner.
We implement amorphous-Al2O3 as а thermally-conductive shield in metallo-dielectric nanolasers, and demonstrate an electrically pumped device. Joint consideration of various design parameters reveals that this design allows the laser to dissipate heat through its shield, aiding thermal management in nanoscale devices.
In a future society with limited access to fossil fuels, technologies for efficient on demand delivery of renewable energy are highly desirable. In this regard, methods that allow for solar energy storage and on demand solar driven energy generation are particularly relevant since the sun is the most abundant energy source.
A single-interface between double-negative and double-positive media acts as a robust perfect-lens whose unbounded resolution endures loss and frequency offsets — unlike existing designs. Its mechanism and performance are reported and compared to the slab lens.
