In particular by their consumption and their supply of electricity. A large part of the new generations of connected objects will only be able to develop if it is possible to make them entirely autonomous in terms of energy. Some manufacturers are therefore developing products capable of recovering energy from their environment. Vital solutions in certain contexts, such as the medical industry. Energy recovery from the environment is a reliable solution to solve the problem of powering wireless connected objects. This paper presents and study a optically transparent solar patch antenna in frequency band of 2.4 GHz for connected objects in the future standard 5G for energy harvesting and RF transmission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=5G" title="5G">5G</a>, <a href="https://publications.waset.org/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/search?q=wireless%20communications" title=" wireless communications"> wireless communications</a>, <a href="https://publications.waset.org/search?q=antenna" title=" antenna"> antenna</a>, <a href="https://publications.waset.org/search?q=solar%20cell." title=" solar cell."> solar cell.</a> </p> <a href="https://publications.waset.org/10011874/antenna-for-energy-harvesting-in-wireless-connected-objects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10011874/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10011874/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10011874/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10011874/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10011874/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10011874/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10011874/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10011874/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10011874/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10011874/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10011874.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">812</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Meshed Antenna for Ku-band Wireless Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Chokri%20Baccouch">Chokri Baccouch</a>, <a href="https://publications.waset.org/search?q=Chayma%20Bahhar"> Chayma Bahhar</a>, <a href="https://publications.waset.org/search?q=Hedi%20Sakli"> Hedi Sakli</a>, <a href="https://publications.waset.org/search?q=Nizar%20Sakli"> Nizar Sakli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this article, we present the combination of an antenna patch structure with a photovoltaic cell in one device for telecommunication applications in isolated environments. The radiating patch element of a patch antenna was replaced by a solar cell. DC current generation is the original feature of the solar cell, but now it was additionally able to receive and transmit electromagnetic waves. A mathematical model which serves in the minimization of power losses of the cell and therefore the improvement in conversion performance was studied.

First, the reduction phase applies a polynomial reduction strategy; that is used for reducing the size problem. Second, the adaptive search procedure is applied in order to attain a feasible solution Finally, the performances of two versions of the proposed algorithm are evaluated on a set of randomly generated instances.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=combinatorial%20optimization" title="combinatorial optimization">combinatorial optimization</a>, <a href="https://publications.waset.org/search?q=max-min%20optimization" title=" max-min optimization"> max-min optimization</a>, <a href="https://publications.waset.org/search?q=knapsack" title=" knapsack"> knapsack</a>, <a href="https://publications.waset.org/search?q=heuristics" title=" heuristics"> heuristics</a>, <a href="https://publications.waset.org/search?q=problem%20reduction" title=" problem reduction"> problem reduction</a> </p> <a href="https://publications.waset.org/11073/the-multi-scenario-knapsack-problem-an-adaptive-search-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11073/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11073/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11073/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11073/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11073/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11073/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11073/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11073/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11073/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11073/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11073.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1618</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> The Knapsack Sharing Problem: A Tree Search Exact Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Mhand%20Hifi">Mhand Hifi</a>, <a href="https://publications.waset.org/search?q=Hedi%20Mhalla"> Hedi Mhalla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, we study the knapsack sharing problem, a variant of the well-known NP-Hard single knapsack problem.

This work treats the texture characterization of trabecular bone radiographs. The aim was to analyze according to clinical research a group of 174 subjects: 87 osteoporotic patients (OP) with various bone fracture types and 87 control cases (CC). To characterize osteoporosis, Fractal and MultiFractal (MF) methods were applied to images for features (attributes) extraction. In order to improve the results, a new method of MF spectrum based on the q-stucture function calculation was proposed and a combination of Fractal and MF attributes was used. The Support Vector Machines (SVM) was applied as a classifier to distinguish between OP patients and CC subjects. The features fusion (fractal and MF) allowed a good discrimination between the two groups with an accuracy rate of 96.22%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Fractal" title="Fractal">Fractal</a>, <a href="https://publications.waset.org/search?q=micro-architecture%20analysis" title=" micro-architecture analysis"> micro-architecture analysis</a>, <a href="https://publications.waset.org/search?q=multifractal" title=" multifractal"> multifractal</a>, <a href="https://publications.waset.org/search?q=SVM" title=" SVM"> SVM</a>, <a href="https://publications.waset.org/search?q=osteoporosis." title=" osteoporosis.

The extension mechanism is provided by UML profiles for RTES. It aims at improving an easily-understood method of system design for non-experts. On the other hand, one of the key items of the co- design methods is the Hardware/Software partitioning and scheduling tasks. Indeed, it is mandatory to define where and when tasks are implemented and run. Unfortunately the main goals of co-design are not included in the usual practice of UML profiles. So, there exists a need for mapping used models to an execution platform for both schedulability test and HW/SW partitioning. In the present work, test schedulability and design space exploration are performed at an early stage. The proposed approach adopts Model Driven Engineering MDE. It starts from UML specification annotated with the recent profile for the Modeling and Analysis of Real Time Embedded systems MARTE. Following refinement strategy, transformation rules allow to find a feasible schedule that satisfies timing constraints and to define where tasks will be implemented. The overall approach is experimented for the design of a football player robot application.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=MDE"
