Geothermal potential mapping of Northeast Morocco (Bekrane-Ahfir) using remote sensing data and GIS

Geothermal energy is part of the renewable energy mix. It is used for heating, air conditioning and sometimes even for the production of electricity. Prospecting for such a resource proves to be a difficult and capital-intensive task. To overcome this constraint, we have used remote sensing which is an adequate tool to guide the prospecting through the elaboration of hydrothermal resource potential maps at the level of zones that present a favorable potential for exploitation (hyper-tectonized sites, volcanic sites, faulted sites, sites with hot geological formations, seismic zones...). The objective of this work is to carry out a study on the North-East of Morocco (Berkane Province), in order to identify favorable sites for geothermal exploitation such as geologically and hydrogeologically active sites. The methodology adopted consists in processing the images of the OLI (Operational Land Imager) and TIRS (Thermal Infrared Sensor) sensors of the Landsat-8 satellite in order to extract spectral indices (Clay mineral Index and Ferrous mineral Index,) detecting a geothermal activity and the surface temperature map (LST) using muticriteria analysis method (MCA). ) in the north-eastern part of Morocco. The results obtained show an almost perfect concordance of the distribution of the above-mentioned indices, with the map of lineaments which are considered as heat drains from the depth to the surface. Moreover, a correct correlation was established during the validation of these results with the map of the inventory of hydrothermal springs identified in the study area.

Achieve high throughput 128 bits FPGA based Advanced Encryption Standard. Background: Field Programmable Gate Array (FPGA) provides an efficient platform for design an AES cryptography system. It provides the capability to control each bit using HDL programming language such as VHDL and Verilog which results from an output speed in Gbps rang. Objective: Use Field Programmable Gate Array (FPGA) to design high throughput 128 bits FPGA based Advanced Encryption Standard. Method: Pipelining technique has been used to achieve the maximum possible speed. The level of pipelining includes round pipelining and internal component pipelining where a number of registers are inserted in particular places to increase the output speed. The proposed design uses combinatorial logic to implement the byte substitution. The s-box was implemented using composed field arithmetic with 7 stages of pipelining to reduce the combinatorial logic level. The presented model has been implemented using VHDL in Xilinx ISETM 14.4 design tool. Result: The achieved results were 18.55 Gbps at a clock frequency of 144.96 MHz and an area of 1568 Slices in Spartan3 xc3s1000 hardware. Conclusion: The results show that the proposed design reaches a high throughput with acceptable area usage compared with other designs in the literature.
Creation of double-well potentials in a surface-electrode trap towards a nanofriction model emulator

Abstract We demonstrate a microfabricated surface-electrode ion trap that is applicable as a nanofriction emulator and studies of many-body dynamics of interacting systems. The trap enables both single-well and double-well trapping potentials in the radial direction, where the distance between the two potential wells can be adjusted by the applied RF voltage. In the double-well configuration, parallel ion strings can be formed, which is a suitable system for the emulation of the Frenkel–Kontorova (FK) model. We derive the condition under which the trap functions as an FK model emulator. The trap is designed so that the Coulomb interaction between two ion strings becomes significant. We report on the microfabrication process for such downsized trap electrodes and experimental results of single-well and double-well operation with calcium ions. With the trap demonstrated in this work we can create atomically accessible, self-assembled Coulomb systems with a wide tuning range of the corrugation parameter in the FK model. This makes it a promising system for quantum simulations, but also for the study of nanofriction in one and higher dimensional systems.

Utilization Of Information Technology In The Field Education (E-education)

The development of information technology makes it easy to communicate the exchange of information so that the place, time and distance are no longer an obstacle. The development of information technology so rapidly could not be separated from the development of computer engineering. Advances in computer and information technology also provides a positive impact on education. Application areas of computer technology and information technology are the most influential in the field of education is the use of computer networks and the Internet. With the internet information services to target students are not limited space, where time and distance. Through the internet information services can be provided as a source of learning, learning media can be studied according to the speed of learners. Media study is not limited to letters and pictures but can be combined with graphics, animations, video, audio together so that the media is better known as multimedia. Positive influence of Internet use for education in developing human resources education should be able to follow the development of science and technology applications. Applications include the industrial world so that graduates are able to meet the demands of the workplace competencies. Based on these facts one way to be able to follow the rapid development of science and technology is to always access the information up to date and all it can in the can over the internet. However, its implementation is still required in support of infrastructure and human resource capabilities well as providers, managers and information users.
THE EMOTIONAL INFECTION OF THE VIRTUAL INNOVATION PROJECT TEAM

Emotional infection is considered as a social and psychological mechanism of transferring the mental mood of the manager to the virtual project team and stakeholders of the projects. Emotional impact in the face of direct contact and the inclusion of the virtual team members in certain mental states have an impact on the effectiveness of project management. The main objective of emotional infection analysis is educated and creates the organization of new behavior in adverse, deadly, and aggressive external conditions the manager or virtual team. In times of global crisis and depression 2.0, the emotional behavior of the innovation project manager and his infection with the project team is exacerbated by external uncertainty. The stakeholder infection model is based on an understanding of the life cycle of the project manager, which is presented as a curve for personal changes of the manager of innovative communication projects and programs. Emotions are considered in content, reflecting the various aspects and meanings that caused them. To apply the psychophysiological formula for assessing the impact of the emotional state of the virtual team of innovative projects, these influences have been transformed into a competent model for managing these projects.
Central Feature Learning for Unsupervised Person Re-identification

The Exemplar Memory (EM) design has shown its effectiveness in facilitating the unsupervised person re-identification (RE-ID). However, there are obvious defects in the update strategies with most existing results, such as the inability to eliminate static errors and ensure convergence stability of learning. To address these issues, in this paper, we propose a novel center feature learning scheme to improve the update strategies of the traditional EM design for unsupervised RE-ID problems. First, the EM module is regarded as a center feature of a cluster of images, then the goal is transformed into pulling the similar images close to while pushing the dissimilar images away from the center feature space. Second, in order to provide effective guidelines on reducing static errors, we propose an error-memory module to improve the central feature learning performances. In addition, an error-prediction module is designed as well to ensure the stability of convergence. Besides, a camera-invariance learning strategy is also introduced to further improve the proposed algorithm. Finally, extensive comparative experiments are conducted on Market-1501 and DukeMTMC-reID datasets to demonstrate the effectiveness and improvements of the proposed method over existing results.

Identification of Multiple Image Steganographic Methods Using Hierarchical ResNets

Image deformations caused by different steganographic methods are typically extremely small and highly similar, which makes their detection and identification to be a difficult task. Although recent steganalytic methods using deep learning have achieved high accuracy, they have been made to detect stego images to which specific steganographic methods have been applied. In this letter, a staganalytic method is proposed that uses hierarchical residual neural networks (ResNet), allowing detection (i.e. classification between stego and cover images) and identification of four spatial steganographic methods (i.e. LSB, PVD, WOW and S-UNIWARD). Experimental results show that using hierarchical ResNets achieves a classification rate of 79.71% in quinary classification, which is approximately 23% higher compared to using a plain convolutional neural network (CNN).

Quasi-classical rules for qubit spin-rotation error suppression

Abstract A frequently encountered source of systematic error in quantum computations is imperfections in the control pulses which are the classical fields that control qubit gate operations. From an analysis of the quantum-mechanical time-evolution operator of the spin wavefunction, it has been demonstrated that composite pulses can mitigate certain systematic errors and an appealing geometric interpretation was developed for the design of error-suppressing composite pulses. Here we show that these same pulse sequences can be obtained within a quasi-classical framework. This raises the question of whether error-correction procedures exist that exploit entanglement in a manner that can not be reproduced in the quasi-classical formulation.

Fine-Grained, Language-Based Access Control for Database-Backed Applications

Context: Database-backed applications often run queries with more authority than necessary. Since programs can access more data than they legitimately need, flaws in security checks at the application level can enable malicious or buggy code to view or modify data in violation of intended access control policies. Inquiry: Although database management systems provide tools to control access to data, these tools are not well-suited for modern applications which often have many users and consist of many different software components. First, databases are unaware of application users, and creating a new database user for each application user is impractical for applications with many users. Second, different components of the same application may require different authority, which would require creating different database users for different software components. Thus, it is difficult to use existing tools to properly limit the authority an application has when executing queries. For this reason, we consider a new, language-based approach to application-specific database security. Approach: Prior work has addressed the difficulty of running applications with least privilege using capability-based security and software contracts, which we adapt to the setting of database-backed applications. Knowledge: This paper's main contribution is the design and implementation of ShillDB, a language for writing secure database-backed applications. ShillDB enables reasoning about database access at the language level through capabilities, which limit which database tables a program can access, and contracts, which limit what operations a program can perform on those tables. ShillDB contracts are expressed as part of function interfaces, making it easy to specify different access control policies for different components. Contracts act as executable security documentation for ShillDB programs and are enforced by the language runtime. Further, ShillDB provides database access control guarantees independent of (and in addition to) the security mechanisms of the underlying database management system. Grounding: We have implemented a prototype of ShillDB and have used it to implement the backend for a lending library reservation system with contracts for each endpoint to evaluate the performance and usability of ShillDB. Further, we benchmark individual database operations in ShillDB to better understand the language's performance overhead. Importance: Our experience indicates that ShillDB is a practical language for enforcing database access control policies in realistic, multi-user applications and has reasonable performance overhead. ShillDB allows developers to reason about security at the component level, safely compose components, and reuse third-party components with their own application-specific database security policies.
Image encryption under spatial domain based on modify 2D LSCM chaotic map via dynamic substitution-permutation network

Image encryption has become an important application aspect of information security. Most attempts are focused on increasing the security aspect, the quality of the resulting image, and the time consumed. On the other hand, dealing with the color image under the spatial domain in this filed is considered as another challenge added to the proposed method that make it sensitivity and difficulty. The proposed method aims to encode a color image by dealing with the main color components of the red (R), green (G), and blue (B) components of a color image to strengthen the dependence of each component by modifying a two dimensional logistic- sine coupling map (2D- LSCM). This is to satisfy the statistical features and reduce time-consumption, and benefit from a mixing step of the second of advanced encryption standard (AES) candidates (serpent block cipher) and modified it to achieve in addition of confusion and diffusion processes. The experimental results showed that our proposed method had the ability to resist against statistical attacks and differential attacks. It also had a uniform histogram, a large key space, complex and faster, closer Shannon entropy to 8, and low correlation values between two adjacent pixels compared with other methods.
