Digital Terrestrial Multimedia Broadcast (DTMB) has high signal coverage and strong stability, so it can be used in Ambient Backscatter Communication (AmBC). To solve the problem of signal detection performance degradation of traditional algorithm in high backscattering rate scenes, this paper presents a signal detection algorithm based on DTMB frame structure. By introducing preamble, the receiver can not only detect the reflected link signal from the received signal, but also perceive the corresponding relationships between the information symbol and the DTMB signal frame; by introducing training symbol, the receiver can get the decision threshold of the information symbol, and then complete the demodulation of the information symbol. Simulation results show that the proposed algorithm significantly improves the signal detection performance.

Accurate photon detection probability (PDP) modeling is important for the optimized design of single-photon avalanche diodes (SPADs) using modern standard CMOS technologies. To ensure a planar active region of a SPAD, the edge of the depletion region must have a lower electric field, so a lower doping concentration is needed. However, this edge effect may have a negative impact on the total PDP, especially for small-sized SPADs. In this paper, we proposed an enhanced PDP modeling process by combining the Technology Computer-Aided Design (TCAD) simulations with machine learning (ML) techniques. Using this ML-TCAD PDP model, we investigated the influence of the edge effect on the PDP of SPADs by varying the diameter of the SPADs from 1.75 μm to 8.75 μm. After generating the sample simulation data, Gaussian process regression (GPR) and deep neuron network (DNN) are applied to train the model. With the application of principal component analysis (PCA), the accuracy of the trained models was significantly improved. Overall, this ML-TCAD PDP model provides an optimized and accelerated design process for SPADs, thus saving simulation time and reducing the design iterations required in the traditional design process of SPADs.

The ECG signals are one of the most important signals to check the human heart’s condition. On monitoring the heart continuously, a large amount of ECG signal data will be produced. So, there is a need for efficient compression techniques. Discrete Anamorphic Stretch Transform (DAST) is one of the most efficient techniques. It is a one-dimensional complex transform that includes the phase recovery technique for recovering the phase from the magnitudes. This paper deals with implementing the phase recovery block in Field Programmable Gate Array (FPGA), which will recover the phase by using magnitudes. Phase recovery block plays a key role in reconstructing the phases from the magnitudes. First, the required signal is passed through the linear filter or phase recovery filter. Then the phase value is estimated using a noniterative algorithm depending on the linearity and causality conditions. The new approach for the phase recovery block is also used for any complex signal transmission. The input ECG signal is taken from the MIT-BIH Arrhythmia database and implementation is carried out in Artix-7 NEXYS 4 DDR FPGA Board. The performance of the phase recovery block is quantified in terms of hardware and computational complexity.

An impetuous popularity of electric vehicles (EVs) is of great concern in the field of automobile research. Since electric vehicles run through electric motor so it is important to have reliable DC-DC boost converter which can give stable required voltage for the motor controller. In this paper a modified cascaded DC-DC boost converter has been presented. The proposed boost converter can achieve high gain at intermediate duty cycle thereby lowering down the conduction loss, which will be ideal for EVs motor controller and other renewables energy applications. The analysis of the proposed converter is performed both in ideal and non-ideal conditions. The analysis of MOSFET’s junction temperature has also been performed in order to confirm its viability for EV’s motor controller and other renewable energy applications.

In recent years, the development of prosthetic limbs has increased due to the various studies that have been carried out around Biomechanics. These technological advances have allowed many amputee patients to return to their daily activities and, in some cases, to recover their social life. However, there are still limitations for some types of prostheses such as passive prostheses, mainly those intended for people with transtibial amputations since they do not perform the physiological function of the joints. Therefore, in-depth research on transtibial prostheses has been carried out. The search period spans from the year 2018 to the year 2021. Information was considered in a simplified and well-structured manner on the design of a transtibial electromechanical prosthesis. Therefore, we will analyze its main features related to its design and application in the patient.

This paper presents a novel optimal control algorithm for coordinated force and motion control of multi rover robotics system with mecanum wheels while manipulating a common payload. Such a system with kinematical rolling conditions lead to non-holonomic constraints. The proposed control algorithm focuses on the minimization of joint torques, the rover-mecanum wheel moments as well as the contact force / moments made with the payload. A quadratic cost function in terms of the joint torques, the wheel moments and the contact forces and moments are minimized to overcome the so called joint torque saturation problem commonly seen while manipulating a common payload and also to provide an optimum solution for such an underdetermined system with non-holonomic constraints Furthermore, the proposed control algorithm provides an on-line trajectory generation capability while manipulating a common payload for both the rovers and the arms simultaneously. The computer simulation results show that the control algorithm works efficiently and the minimum joint torques, and the contact forces and moments can be obtained while the end-effectors are manipulating and tracking a desired payload trajectory.

Various researchers have studied how to increase the performance of thermoelectric cooling devices by optimizing their module design. In the present study, the researchers investigate whether a truncated square pyramid leg geometry results to a higher COP than a symmetrical rectangular leg by varying the middle and contact areas. The values of the input parameters for the thermal-electric analysis were generated using a sphere packing design. Then, the different leg geometries were modelled in FUSION 360 and simulated in ANSYS to determine the COP from the resulting hot and cold side temperatures. Afterward, a mathematical model was generated using Gaussian Process modelling to model COP as a function of the middle and contact areas. By maximizing the desirability function of the model, results show that for the experimental design space considered for this study (contact area: 0.108 mm2 < AC < 1.000 mm2; middle area: 1.150 mm2 < AM < 2.560 mm2), the highest COP was attained at AC = 1.000 mm2 and AM = 1.150 mm2. The researchers therefore conclude that an asymmetrical truncated square pyramid leg geometry yields a higher COP compared to a symmetrical rectangular leg geometry, which is consistent with the results of past studies.
许多研究者研究了如何通过优化热电冷却装置的模块设计来提高其性能。在本研究中，研究人员通过改变中间和接触面积来研究截断的方形金字塔腿几何形状是否比对称矩形腿产生更高的COP。热电分析的输入参数值是用球体填充设计生成的。然后，在FUSION 360中对不同的支腿几何形状进行建模，并在ANSYS中进行仿真，从而根据所得的冷热侧温度确定COP。然后，利用高斯过程建模建立了COP作为中间和接触面积函数的数学模型。通过最大化模型的期望函数，结果表明，对于本研究考虑的实验设计空间(接触面积:0.108 mm2 < AC < 1.000 mm2;中间面积:1.150 mm2 < AM < 2.560 mm2)，在AC = 1.000 mm2和AM = 1.150 mm2时COP最高。因此，研究人员得出结论，与对称的矩形腿的几何形状相比，不对称的正方形金字塔腿的几何形状产生更高的COP，这与过去的研究结果一致。

In order to satisfy the current needs of urban grassroots governance, a novel city hotline service ontology is constructed to improve the efficiency and effectiveness of city hotline service in this paper. Firstly, the TOVE method is applied to construct government hotline service ontology for urban grassroots governance based on the cases of city hotline service. Secondly, the necessary concepts are defined, including the hierarchical relationships, attributes, and constraints among the seven modules of the city, personnel, organization, government, hotline appeal, hotline complaint object, and hotline processing results. Finally, the city hotline service ontology is built with the protégé ontology development tool and then tested in hotline scenarios of different urban grassroots governance. The testing results verify the validity and practicability of the proposed ontology so that the needs of hotline service are met in urban grassroots governance.
