In this work we investigate the consequences of running gravitational coupling on the properties of rotating black holes. Apart from the changes induced in the spacetime structure of such black holes, we also study the implications to Penrose process and geodetic precession. We are motivated by the functional form of gravitational coupling previously investigated in the context of infra-red limit of asymptotic safe gravity theory. In this approach, the involvement of a new parameter ξ~ in this solution makes it different from Schwarzschild black hole. The Killing horizon, event horizon and singularity of the computed metric is then discussed. It is noticed that the ergosphere is increased as ξ~ increases. Considering the black hole solution in equatorial plane, the geodesics of particles, both null and time like cases, are explored. The effective potential is computed and graphically analyzed for different values of parameter ξ~. The energy extraction from black hole is investigated via Penrose process. For the same values of spin parameter, the numerical results suggest that the efficiency of Penrose process is greater in quantum corrected gravity than in Kerr Black Hole. At the end, a brief discussion on Lense-Thirring frequency is also done. Copyright © 2017, The Authors. All rights reserved.

This study follows the new concept of the OnLine Electric Vehicle (OLEV) using the wireless charging technology as one of contactless electric power transfer technologies for Electric Vehicle (EV) charging. This electric transport system, which has been developed by Korea Advanced Institute of Science and technology (KAIST), allows vehicles to charge their battery while in motion. In this paper, we used integer programming to find the minimum total investment cost that considers the OLEV system with a multiple route; afterwards, we introduced the resolution of this problem with the particle swarm optimization as the particles showed their robustness against nonlinear optimization problems.

Nowadays, videos are mostly multiplexed with au-dios and wrapped in a multimedia container format. With speedy consumption of videos being a norm these days, authenticating video files (video + audio) becomes a challenging task. Conventional authentication schemes only focus on individual track such as audio or video. Therefore, in this work, we propose an authentication system where authentication values from video and audio are weaved by exploiting data embedding techniques in the compression/media layer and system layer. Specifically, the authentication value from video is embedded into audio, and vice versa. The authentication values for both audio and video are generated by using the key embedded in the system layer and cryptographic hash function. As a proof of concept, the ideas are implemented on MP4 format container and evaluated using various short movie clips downloaded from YouTube. Results suggest that imperceptible quality degradation and insignificant file size increment were achieved.

Underestimating facility location decisions may penalize its performance over time. Those penalties usually have been studied from the economic point of view analyzing its impact on profitability. At the same time, the concern about the obtaining of sustainability is gaining importance leading to seek for renewable energy sources to reduce greenhouse gas emissions. However, little attention has been paid on choosing a location considering environmental criteria. Thus, this work aims at determining a biorefinery location considering its impacts on natural resources. Thus, a mixed integer linear programming model is developed taking into account the crop location and the biomass production seasonality to obtain an apposite location that minimizes environmental impact. © Copyright AGH-UST, Kraków, Polska, 2016.

Fingerprint classification is one of the most common approaches to accelerate the identification in large databases of fingerprints. Fingerprints are grouped into disjoint classes, so that an input fingerprint is compared only with those belonging to the predicted class, reducing the penetration rate of the search. The classification procedure usually starts by the extraction of features from the fingerprint image, frequently based on visual characteristics. In this work, we propose an approach to fingerprint classification using convolutional neural networks, which avoid the necessity of an explicit feature extraction process by incorporating the image processing within the training of the classifier. Furthermore, such an approach is able to predict a class even for low-quality fingerprints that are rejected by commonly used algorithms, such as FingerCode. The study gives special importance to the robustness of the classification for different impressions of the same fingerprint, aiming to minimize the penetration in the database. In our experiments, convolutional neural networks yielded better accuracy and penetration rate than state-of-the-art classifiers based on explicit feature extraction. The tested networks also improved on the runtime, as a result of the joint optimization of both feature extraction and classification. Copyright © 2017, The Authors. All rights reserved.

Tabletop systems support simultaneous multi-user multi-touch interaction to select and manipulate digital contents such as text, images, and videos directly and in a natural way. These digital contents require the proper orientation to perform co-located collaborative tasks. To achieve this, some orientation techniques are also proposed in different domains. But, the orientation issue is still reported for collaborative medical image analysis around tabletop systems. The presence of the inappropriate digital content-orientation on tabletop displays limits the collaborative medical image analysis. It also decreases the visibility, accessibility and readability of digital contents during co-located collaborative interaction. This paper presents a user study to evaluate usability of the two different orientation techniques for diagnosing and monitoring of medical images from the user perspective. Subsequently, the comparative analysis of those techniques is presented and discussed based on the obtained data. The findings suggest that the manual-orientation technique provide better usability as compared to the global-orientation technique for diagnosing and monitoring the medical images. Finally, the future work is suggested based on the obtained findings to enhance the usability.

The two-dimensional boundary layer flow of an Oldroyd-B fluid in the presence of nanoparticles is investigated. Convective heat and mass conditions are considered in the presence of thermal radiation and heat generation. The Brownian motion and thermophoresis effects are retained. The nonlinear partial differential equations are reduced into the ordinary differential equation （ODE） systems. The resulting ODE systems are solved for the series solutions. The results are analyzed for various physical parameters of interest. Numerical values of the local Nusselt and Sherwood numbers are also computed and analyzed.

Classical novae are cataclysmic binary star systems in which the matter of a companion star is accreted on a white dwarf1,2. Accumulation of hydrogen in a layer eventually causes a thermonuclear explosion on the surface of the white dwarf3, brightening the white dwarf to ~105 solar luminosities and triggering ejection of the accumulated matter. Novae provide the extreme conditions required to accelerate particles, electrons or protons, to high energies. Here we present the detection of gamma rays by the MAGIC telescopes from the 2021 outburst of RS Ophiuchi, a recurrent nova with a red giant companion, which allowed us to accurately characterize the emission from a nova in the 60 GeV to 250 GeV energy range. The theoretical interpretation of the combined Fermi LAT and MAGIC data suggests that protons are accelerated to hundreds of gigaelectronvolts in the nova shock. Such protons should create bubbles of enhanced cosmic ray density, of the order of 10 pc, from the recurrent *** of the 2021 outburst of the nova RS Oph in very-high-energy gamma rays by the MAGIC telescopes is reported. Investigation of the gamma-ray emission provides evidence for acceleration of protons within the nova shock, which then propagate outwards to create bubbles of enhanced cosmic ray density.
