Throughout this work, outputs of two optimization techniques are compared with each other in terms of antenna placements and coupling results.

In this paper, taking a 9-element nonuniform linear array as an example and the desired radiation pattern corresponding to a Chebyshev distribution as the optimization objective, optimize the excitations and locations of the elements.

The synergy effect of energy and water has rarely been considered in the process of energy and water saving in China, where its contribution cannot be maximized. Energy sectors consume large amounts of energy and water when producing massive energy, which makes them both energy and water intensive. Therefore, the synergy effect in these sectors is significant. This paper assesses and optimizes the synergy effect in three energy sectors under the background of promoting energy and water saving. Results show that: From the perspective of critical path, chemical industry, mining and processing of non-metal ores and smelting and pressing of metals are coupling points in the process of energy and water flowing to energy sectors, in which the implementation of energy and water saving policies can bring significant synergy effect. Multi-objective optimization shows that increasing efforts on input restructuring can effectively improve synergy effects; relatively large synergetic energy saving and little water saving are obtained after solely reducing the energy and water intensity of coupling sectors. By optimizing the input structure of sectors, especially the coupling sectors, the synergy effect of energy and water saving can be improved in energy sectors under the premise of keeping economy running stably. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20path" title="critical path">critical path</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20sector" title=" energy sector"> energy sector</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-objective%20optimization" title=" multi-objective optimization"> multi-objective optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=synergy%20effect" title=" synergy effect"> synergy effect</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a> </p> <a href="https://publications.waset.org/abstracts/62192/synergy-effect-of-energy-and-water-saving-in-chinas-energy-sectors-a-multi-objective-optimization-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62192.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">360</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3889</span> Investigation on the Behavior of Conventional Reinforced Coupling Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akash%20K.%20Walunj">Akash K.

The behavior of coupled shear walls is mainly governed by the coupling beams. The coupling beams are designed for ductile inelastic behavior in order to dissipate energy. The base of the shear walls may be designed for elastic or ductile inelastic behavior. The amount of energy dissipation depends on the yield moment capacity and plastic rotation capacity of the coupling beams. In this paper, an analytical model of coupling beam was developed to calculate the rotations and moment capacities of coupling beam with conventional reinforcement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20studies" title="design studies">design studies</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20model%28s%29" title=" computational model(s)"> computational model(s)</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20study%2Fstudies" title=" case study/studies"> case study/studies</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=coupling%20beam" title=" coupling beam"> coupling beam</a> </p> <a href="https://publications.waset.org/abstracts/3310/investigation-on-the-behavior-of-conventional-reinforced-coupling-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3310.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">476</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3888</span> Flexible Coupling between Gearbox and Pump (High Speed Machine)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naif%20Mohsen%20Alharbi">Naif Mohsen Alharbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper present failure occurred on flexible coupling installed at oil anf gas operation.

This report provides the study intentionally for continues operation optimization, utilize the advanced opportunity and implement a improvement. Objective: The main objectives of the investigation are identifying the root causes, solving and developing the technology designs or bad actor. Ultimately, fulfilling the operation productivity, also ensuring better technology, quality and design by solutions. This report provides the study intentionally for continues operation optimization, utilize the advanced opportunity and implemet improvement. Method: The method used in this project was a very focused root cause analysis procedure that incorporated engineering analysis and measurements. The analysis method extensively covers the measuring of the complete coupling dimensions. Including the membranes thickness, hubs, bore diameter and total length, dismantle flexible coupling to diagnose how deep the coupling has been affected. Also, defining failure modes, so that the causes could be identified and verified. Moreover, Vibration analysis and metallurgy test. Lastly applying several solutions by advanced tools (will be mentioned in detail). Results and observation: Design capacity: Coupling capacity is an inadequate to fulfil 100% of operating conditions. Therefore, design modification of service factor to be at least 2.07 is crucial to address this issue and prevent recurrence of similar scenario, especially for the new upgrading project. Discharge fluctuation: High torque flexible coupling encountered during the operation. Therefore, discharge valve behaviour, tuning, set point and general conditions revaluated and modified subsequently, it can be used as baseline for upcoming Coupling design project.

The connectivity among these class members and the relationship between the class and other classes play an important role in determining the quality of an object-oriented system. Class cohesion evaluates the degree of relatedness of class attributes and methods, whereas class coupling refers to the degree to which a class is related to other classes. Researchers have proposed several class cohesion and class coupling measures. However, the correlation between class coupling and class cohesion measures have not been thoroughly studied. In this paper, using classes of three open-source Java systems, we empirically investigate the correlation between several measures of connectivity-based class cohesion and coupling. Four connectivity-based cohesion measures and eight coupling measures are considered in the empirical study. The empirical study results show that class connectivity-based cohesion and coupling internal quality attributes are inversely correlated.

Among them, the capacitive coupling wireless power transfer, also named Capacitive Coupling Wireless Power Transfer (CCWPT), has been researched to overcome the drawbacks of other approaches. The CCWPT has many advantages such as a simple structure, low standing power loss, reduced Electromagnetic Interference (EMI) and the ability to transfer power through metal barriers.

The purpose of this research had been to investigate the problem of anti-phase synchronization for complex delayed dynamical networks with output coupling. The coupling configuration is general, with the coupling matrix not assumed to be symmetric or irreducible. The amount of the coupling variables between two connected nodes is flexible, the nodes in the drive and response systems need not to be identical and there is not any extra constraint on the coupling matrix. Some pinning controllers are designed to make the drive-response system achieve the anti-phase synchronization. For the convenience of description, we applied the matrix Kronecker product. Some new criteria are proposed based on the Lyapunov stability theory, linear matrix inequalities (LMI) and Schur complement. Lastly, some simulation examples are provided to illustrate the effectiveness of our proposed conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-phase%20synchronization" title="anti-phase synchronization">anti-phase synchronization</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20networks" title=" complex networks"> complex networks</a>, <a href="https://publications.waset.org/abstracts/search?q=output%20coupling" title=" output coupling"> output coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=pinning%20control" title=" pinning control"> pinning control</a> </p> <a href="https://publications.waset.org/abstracts/38055/anti-phase-synchronization-of-complex-delayed-networks-with-output-coupling-via-pinning-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38055.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">394</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3881</span> Substrate Coupling in Millimeter Wave Frequencies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vasileios%20Gerakis">Vasileios Gerakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Fontounasios%20Christos"> Fontounasios Christos</a>, <a href="https://publications.waset.org/abstracts/search?q=Alkis%20Hatzopoulos"> Alkis Hatzopoulos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A study of the impact of metal guard rings on the coupling between two square metal pads is presented.

The FAT method, also called RIFF method (Filtered Windowed Inverse Resolution), allows to identify the force distribution from local vibration field. In order to only identify the external force applied on a structure, it is necessary to quantify the fluid-structure coupling, especially in naval application, where the fluid is heavy. This method can be decomposed in two parts, the first one consists in identifying the fluid-structure coupling and the second one to introduced it in the FAT method to reconstruct the external force.

The method concerns the optimized geometry of a structure that may be used to host the tuning elements, which are typically RF (Radio Frequency) switches. The tuning elements themselves, and their performance during tuning, are not the focus of this paper. The designed resonator is able to reconfigure its fractional bandwidth by adjusting the inter-coupling level between the degenerate modes, while at the same time improving its response by adjusting the external-coupling level and keeping the center frequency fixed. The inter-coupling level has been adjusted by changing the dimensions of the perturbation element, while the external-coupling level has been adjusted by changing one of the feeder dimensions. The design was arrived at via optimization. Agreeing simulation and measurement results of the designed and implemented filters showed good improvements in return loss values and the stability of the center frequency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dual-mode%20resonators" title="dual-mode resonators">dual-mode resonators</a>, <a href="https://publications.waset.org/abstracts/search?q=perturbation%20theory" title=" perturbation theory"> perturbation theory</a>, <a href="https://publications.waset.org/abstracts/search?q=reconfigurable%20filters" title=" reconfigurable filters"> reconfigurable filters</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20defined%20radio" title=" software defined radio"> software defined radio</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitine%20radio" title=" cognitine radio "> cognitine radio </a> </p> <a href="https://publications.waset.org/abstracts/118849/improving-the-frequency-response-of-a-circular-dual-mode-resonator-with-a-reconfigurable-bandwidth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118849.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">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3875</span> Mutual Coupling Reduction between Patch Antenna Array Elements Using Metamaterial Z Shaped Resonators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oossama%20Tabbabi">Oossama Tabbabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mondher%20Labidi"> Mondher Labidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fethi%20Choubani"> Fethi Choubani</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20David"> J.

Uniform nodes are ensured at the interfaces of the coupling element with each waveguide. Then, equilibrium and continuity conditions are enforced at the interfaces. Wave propagation properties of each waveguide are calculated using the WFE method and the coupling element is modelled using the FE method. The scattering of waves through the coupling element, on which damage is modelled, is determined by coupling the FE and WFE models.

The coupling medium is placed between the scanned object and the ultrasound transducers. Water with varying temperature was used as the coupling medium. The water temperature is gradually varied between 25 to 40 degrees. This heating process is taken with care in order to avoid the bubble formation. Rise in the photoacoustic signal is noted through an unfocused transducer with frequency of 2.25 MHz as the temperature increases.

Also the temperature is transmitted to PC through a serial communication.

In this method piezoelectric transducers are normally held in direct contact with the concrete surface. The current study aims to test the hypothesis that a preferential coupling effect might exist i.e. that the speed of sound measured depends on the couplant used. In this study, different coupling media of varying acoustic impedance were placed between the transducers and concrete samples made with constant aggregate content but with different compressive strengths. The preliminary results show that using coupling materials (both solid and a range of liquid substances) has an effect on the pulse velocity measured in a given concrete. The effect varies depending on the material used. The UPV measurements with solid coupling were higher than these from the liquid coupling at all strength levels. The tests using couplants generally recorded lower UPV values than the conventional test, except when carbon fiber composite was used, which retuned higher values. Analysis of variances (ANOVA) was performed to confirm that there are statistically significant differences between the measurements recorded using a conventional system and a coupled system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title="compressive strength">compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=coupling%20effect" title=" coupling effect"> coupling effect</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic" title=" ultrasonic"> ultrasonic</a> </p> <a href="https://publications.waset.org/abstracts/40930/effect-of-coupling-media-on-ultrasonic-pulse-velocity-in-concrete-a-preliminary-investigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40930.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">321</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3870</span> Cross Coupling Sliding Mode Synchronization Control of Dual-Driving Feed System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hong%20Lu">Hong Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Fan"> Wei Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongquan%20Zhang"> Yongquan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Junbo%20Zhang"> Junbo Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A cross coupling sliding synchronization control strategy is proposed for the dual-driving feed system.

These rods can be linked together via U-coupling easily. The system is self-stimulated and may cause instabilities due to the inherent behavior of the coupling. In this study, each rod includes an elastic shaft with an angular stiffness and structural damping. Moreover, the mass of shafts is considered via attached solid disks. The impact of the system architecture and shaft mass on the instability of such mechanism are studied. Stability charts are plotted via a method based on Floquet theory. Eventually, the unstable points have been found and analyzed in detail. The results show that stabilizing the driveline is feasible by changing the system characteristics which include shaft mass and architecture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coupling" title="coupling">coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20systems" title=" mechanical systems"> mechanical systems</a>, <a href="https://publications.waset.org/abstracts/search?q=oscillations" title=" oscillations"> oscillations</a>, <a href="https://publications.waset.org/abstracts/search?q=rotating%20shafts" title=" rotating shafts"> rotating shafts</a> </p> <a href="https://publications.waset.org/abstracts/98061/stability-of-a-self-excited-machine-due-to-the-mechanical-coupling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98061.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">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3865</span> Ultrastrong Coupling of CdZnS/ZnS Quantum Dots and Breathing Plasmons in Aluminum Metal-Insulator-Metal Nanocavities in Near-Ultraviolet Spectrum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Li">Li Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Wang"> Lei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chenglin%20Du"> Chenglin Du</a>, <a href="https://publications.waset.org/abstracts/search?q=Mengxin%20Ren"> Mengxin Ren</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinzheng%20Zhang"> Xinzheng Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Cai"> Wei Cai</a>, <a href="https://publications.waset.org/abstracts/search?q=Jingjun%20Xu"> Jingjun Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Strong coupling between excitons of quantum dots and plasmons in nanocavites can be realized at room temperature due to the strong confinement of the plasmon fields, which offers building blocks for quantum information systems or ultralow-power switches and lasers.

The Qi system comprises a power transmission pad and a compatible receiver in a portable device which is placed on top of the power transmission pad, which charges using the principle of electromagnetic induction. An alternating current is passed through the transmitter coil, generating a magnetic field. This, in turn, induces a voltage in the receiver coil; this can be used to power a mobile device or charge a battery. The efficiency of the power transfer depends on the coupling (k) between the inductors and their quality (Q) The coupling is determined by the distance between the inductors (z) and the relative size (D2 /D). The coupling is further determined by the shape of the coils and the angle between them. If the receiver coil is at a certain distance to the transmitter coil, only a fraction of the magnetic flux, which is generated by the transmitter coil, penetrates the receiver coil and contributes to the power transmission. The more flux reaches the receiver, the better the coils are coupled. <p class="card-text"><strong>Keywords:</strong> <a
