In this paper, a continuous beam scanning leaky-wave antenna (LWA) is proposed for terahertz (THz) applications. The proposed LWA uses Ridge Gap Waveguide (RGW) technology which is alternated with silicon rods. As its primary advantage, this LWA has gapless dispersion with linear behavior, which is often suffered by conventional LWAs. Also, the equivalent circuit of LWA is provided that verifies the proper closure of the bandgap. As operating frequencies increase from 430 to 550 GHz, the proposed LWA achieves a continuous beam steering about 85°, scanning from forward to broadside and then the backward direction with stable high gains and no degradation at broadside. The proposed LWA provides a simple solution for THz applications.

Residential buildings are estimated to have a significant percentage of energy consumption in the world. Demand-side management (DSM) improves the grid stability by providing economic incentives with increasing flexibility in demand and reducing a peak to average ratio. The success of applications in DSM heavily depends on the welfare and satisfaction of consumers, or a significant reduction of the customers electricity bill. In this paper, the genetic algorithm is used to optimize the problem. Moreover, two scenarios are discussed. In the first one, occupants have announced their preferred time of household appliances usage. On this basis, the scheduled for the use of household appliances is optimally determined in order to minimize the cost of electricity usage in addition to meeting end-user preferences on when to use devices. In the second one, customers are offered a significant reduction in their electricity bill by changing the operation time of some of their household appliances. The proposed model is implemented for the hottest day of 2018 in New York City. The results demonstrate that the consumers preference is satisfied, and the peak load is declined down to the value, which is desirable for the utility. Besides, the model doesn't produce a new peak load when the power price is low. Hence the system stability is increased, which reflects the significant effectiveness of this model.

Transformer-less inverters are widely used in grid-tied photovoltaic (PV) applications due to their characteristics such as higher efficiency and lower price. In common-ground transformer-less PV inverters, the neutral point of grid is connected to the negative polarity of the PV panel directly to bypass the parasitic capacitances and to mitigate the leakage current. In this study, a single phase transformer-less grid-tied inverter is proposed and to obtain the unique characteristics of the recommended grid-connected topology, the series-parallel switching technique of the switched capacitor module in a packed unit is applied. Also, by utilizing the common grounding method, the leakage current is eliminated. The provided inverter can generate three-level output voltage waveform. To generate the switching gate pulses of utilized power switches, the peak current controller method is applied. The injected power flows (active and reactive powers) are adjusted using peak current control (PCC) method. Finally, a completely adjusted sinusoidal current can be delivered to power grid. In the next section, the operation procedure, comparison results are presented. Finally, to verify the accurate operation and the theoretical equations of the proposed inverter, simulation results are presented.

Commercial biopotential electrodes for Electromyography (EMG), Electrocardiography (ECG) and Electroencephalography (EEG) are rigid and inflexible. Due to the use of conductive gels and the adhesive pads, these electrodes are disposable, thus unsuitable for long-term use. Flexible dry electrodes in the literature have been reported to record the biological signals relatively well. Although there are still challenges in this emerging field of research to overcome in the near future. In this manuscript, we have fabricated flexible dry electrodes to record the surface EMG (sEMG) signals. Five hand motions are classified based on the sEMG signals recorded by our electrodes as well as commercially available wet rigid electrodes. The recognition accuracy reaches proximately 85% and 82% for the sEMG signals recorded by the dry and wet electrodes, respectively. Gaussian SVM algorithm is used as the most appropriate classifier here. The classifier accuracy is found out to be relatively similar comparing the commercial wet electrodes to our fabricated dry counterparts.

Non-Orthogonal Multiple Access (NOMA) is an enabling technique proposed for the Fifth Generation (5G) and beyond. In NOMA every Resource Block (RB) such as a time slot, subcarrier, or spreading code is assigned to multiple users. Consequently, as the main goal of NOMA compared to Orthogonal Multiple Access (OMA) techniques, the number of supported users for each RB increases. Regarding the situation of the network, higher total network rate, fairness, Energy Efficiency (EE) and Spectrum Efficiency (SE), as the lateral NOMA goals compared to OMA, can be also achieved. In this paper, maximizing fairness by satisfying the required Quality of Service (QoS) for all users is investigated. Theoretical and simulation results present the superiority of the proposed model in optimizing fairness.

Stroke is the principal cause of death all over the world. Lesion detection is a crucial step in diagnosis and therapy of patients with stroke lesion. MRI is useful device in lesion segmentation that produces different brain image series, such as T1, T2 and FLAIR. Nowadays, automatic methods for detecting lesion are preferable to semi-automatic methods due to their speed, flexibility and availability. So, the efficiency of these methods in detecting lesion is important. LST-Lesion segmentation tool by SPM is an automatic tool which is most commonly used to detect Multiple Sclerosis (MS) lesions. Moreover, the LST has been investigated for detecting of stroke lesions. In this study the operation of this tool is examined both in the old version (SPM8) and the new one (SPM12) in a wide range of lesion volumes of ischemic stroke. The results show that LST can be used as an automated tool for detecting of stroke lesions but it works better in old version. Also, the performance of the LST in detection of lesions is improved by two feature maps. These feature maps separate missed and abnormal pixels. These two properties have more effects in detection of large lesions which are detected with high quality.

With an increased interest in utilizing the mmWave, beamforming has drawn more attention in recent years. Aside from all the improvements obtained via beamforming, it is an adherent technique in mmWave systems due to the severe path loss in such systems. Practical considerations have emerged hybrid structures for implementing this technology. Hybrid beamforming systems rely on phase shifters in their analog stage. Designing tunable phase shifters with high precision is hard and costly, hence in practical systems, discrete phase shifters are favored. In this paper, we propose a novel method to design the hybrid beamforming system. The focus of this paper is to formulate the hybrid beamforming design problem with discrete phase shifters in a discrete optimization problem form and provide simple methods to obtain its solution. The proposed methods are computationally efficient and can provide comparable performance to the current line of work in this field.

In generalized frequency division multiplexing (GFDM) technique, the data symbols are transmitted on different time and frequency by using non-orthogonal pulse shapes. This causes two dimensional self-interference (SI) among the transmitted symbols. Recently, a modified version of GFDM, coded GFDM (CGFDM), has been introduced avoiding the noise enhancement during SI cancellation by providing a unitary SI matrix. In this paper, we generalize the CGFDM idea to be used in the uplink of a multiuser transmission scenario, and develop a zero-forcing (ZF) receiver to detect data symbols of multiple users. Simulation results show that the proposed ZF based transceiver outperforms the conventional ZF based generalized frequency division multiple access transceiver when the number of subsymbols is high and the prototype filter is less localized, with just a slight increase in computation complexity.

In the current article, we describe a resistive switching random access memory based on a homogenized mixture of Graphene oxide(GO) and PEDOT:PSS(PP). To make a comparison, memory devices with GO and PP were fabricated and characterized too. It is found that blending previous materials significantly change the hysteresis properties of memories in a good way. In our experiment, the structure Al/GO-PP(1:1)/ITO demonstrated good switching behavior with approximately 102 on/off current ratio, low 3V set/reset voltage, high 6000 sec retention time, symmetrical hysteresis curve and small energy consumption.
