The simulation method is based on the non-equilibrium Green's function formalism. It has been found that the dilation in the band-to-band tunneling (BTBT) window near the source induced by the electrostatic effects of the upward gate work function, is efficient in mitigating the BTBT mechanism as well as its associated detrimental effects. As result, improvements in terms of switching characteristics have been reached, where lower leakage current, reduced ambipolar behavior, and improved current ratio are recorded. The obtained results indicate that the upward gate work-function technique is an intriguing improvement method that can be applied to boost the performance of other nano-FETs suffering from the BTBT such as the graphene nanoribbon field-effect transistors.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132876965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The excessive application of wires also increases the possibility of a short circuit and fire sparks. Wireless power transfer (WPT) is an excellent alternative for this problem that would eliminate cables and increase electrical safety. The current challenge of wireless power transfer is distance and misalignment. This paper investigates the effect of EH with WPT. The system works under a wide band of frequencies from 26 Hz to 30 Hz and various accelerations from 0.14 g to 0.19g. The harvester was implemented with electronic components and experimentally tested to determine the maximum generated power which is 330 m W at 560 Ω as load impedance at 29 Hz of the resonance frequency. Results showed that at an ideal distance and alignment and under different accelerations, the output voltage of the rectifier increased to 4.2 V at 0.19 g, and the DC-DC converter is stable to 3.2 V. The output voltage of the receiving coil is decreasing as the distance and the lateral misalignment are decreasing. The output voltage of the receiving coil value is obtained when the system is in ideal alignment and distance. The system can work under a wideband of distance from 0 mm to 8 mm and a wideband of lateral misalignment from 0 mm to 5 mm.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132376104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adaptive fuzzy models are employed to online approximate some uncertain smooth functions. Unlike many neighboring works, this paper carefully solves the open problem of the feasibility of the virtual control laws in the barrier Lyapunov function-based control design framework. By using disturbance observers in a backstepping framework, the estimation errors due to the use of a priori bounded virtual control law are appropriately compensated and the “explosion of complexity” is practically avoided. The proposed controller ensures the convergence of the output tracking error to an arbitrarily tiny neighborhood of the origin, boundedness of all closed-loop signals and no-violation of the predefined state constraints. A numerical example is provided to validate the effectiveness of the proposed method.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133756683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The implemented FBG network allows the estimation of the vibration positions on the aircraft wings. Based on the measurements taken and if the wing vibration exceeds a preset threshold, the decision is made to reduce the aircraft's speed in order to decrease the vibrations. A series of laser pulses is transmitted to the deployed FBG arrays to achieve this goal. When an external strain is applied to the wing, the deployed FBG responds by shifting the reflected wavelength proportionally. A data acquisition module estimates the FBG displacement and fiber elongation in a given FBG point in the wing based on the wavelength of the reflected optical pulse.","PeriodicalId":253898,"journal":{"name":"2022 19th International Multi-Conference on Systems, Signals & Devices (SSD)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122171248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the various methods that aim to overcome this issue is to select groups of nodes that are disjoint and are called dominating sets (DS). Each group carry out the tasks on behalf of their nearby nodes. This helps to prolong network lifespan by distributing data collection responsibilities across these groups, such that one group is responsible for handling these tasks then, after a certain period of time, another group replaces it, and so on. The goal of this paper is to identify energy-aware disjoint DSs that extend the lifetime for a given network with heterogeneous energy.
