Advanced networks born after the development of the commercial Internet, those networks are the infrastructure of the national research and education networks around the world, acting as Internet version 2 for each country. The backbone internet infrastructure is so expensive that just a few internet service providers in a country can invest and deliver these networks. Therefore, when academics wish to explore management in these backbone internet networks a simulator or emulator must be used and GNS3 is often chosen because it supports backbone routers and Gbps links. Advanced networks have evolved and updating the backbone infrastructure until Gbps and using backbone routers. In this work a connectivity and management emulator for the backbone topology of different advanced networks in the globe is explored and, its capabilities and limitations are shown, but when approaching the real backbone infrastructure, CANARIE is chosen.

Nowadays, a carbon nano (CN) structure is used in a variety of biomedical applications, including cancer disease diagnostics and subsequent treatments. Among the various types of CN, carbon nanotube (CNTs) has been implemented by many research groups for an array of life science applications. Because of the microstructure shape of Nanotube they can be widely used in carrier and separation applications. Conjugation of CNTs with proteins, drugs and magnetic nanoparticles provides the chance of targeting and trajectory manipulation. Moreover, the force needed for crossing through a specific area such as cell membrane or tissue is essential for successful targeting. In this paper, we studied functionalized CNTs' controlled delivery crossing through the cell membrane. All interaction effects have been carried out by MD (Molecular Dynamics Simulation). Mathematical modelling of the cell membrane and proposed delivery system as an input-output (velocity-force) system has been considered. Dynamics equations of CNTs were defined in the time and frequency domain using control theory methods. This system dynamic helps the researcher to analyze the movement dynamics of an accurate model during the time. Data are collected from MD simulation and a linear model is estimated. This model has been calculated by the identification method based on the MATLAB toolbox.
如今,碳纳米(CN)结构被用于各种生物医学应用,包括癌症疾病诊断和后续治疗。在各种类型的碳纳米管中,碳纳米管(CNTs)已被许多研究小组用于一系列生命科学应用。由于纳米管的微观结构,其在载体和分离领域有着广泛的应用。碳纳米管与蛋白质、药物和磁性纳米颗粒的结合提供了靶向和轨迹操纵的机会。此外,穿过特定区域(如细胞膜或组织)所需的力对于成功靶向是必不可少的。在本文中,我们研究了功能化碳纳米管通过细胞膜的控制传递。所有相互作用效应均由分子动力学模拟(MD)进行。考虑了细胞膜的数学模型和作为输入-输出(速度-力)系统提出的递送系统。利用控制理论方法在时域和频域定义了碳纳米管的动力学方程。该系统动态有助于研究人员在此期间准确分析模型的运动动态。从MD仿真中收集数据,估计线性模型。利用MATLAB工具箱中的辨识方法对该模型进行了计算。

A new multispectral camera configuration based on multiple sensors with multiple filters using CMOS sensors and MIPI protocol in a mobile processing technology platform is described. We introduce two schemes using the camera either in video mode or in trigger mode of operation. We show how accurate time management makes it possible to multiplex MIPI coded image data and achieve fast imaging. We compare the schemes. As system simplicity and low power consumption were our goals, we have no image buffer memory and our scheme is asynchronous in nature. However we will discuss means to decrease intra frame latency.

This paper reports on a novel solution for fault detection, identification, and recovery in autonomous underwater vehicles using partially observable Markov decision processes (POMDP). It explains the reasoning for using - POMDP model-based fault manager over traditional static look-up tables. A generic long-endurance AUV was simulated with selected sub-systems as a proof-of-concept. The POMDP was applied to the fault management system to determine the actions of the vehicle given a fault in either the environment or vehicle. The simulation test bed that was developed is described. The results from simulations were performed using both synthetically generated and actually measured bathymetry data. The results are very encouraging.

Internet of Things (IoT) and IoT applications will experience significant growth as the fifth-generation (5G) of wireless technology matures and becomes more widely adopted. How to power on billions of low power wireless IoT devices has initiated a new interest in energy harvesting. The 5G technology will open new opportunities to design circuits to efficiently extract energy from millimeter waves to power on IoT devices. In this paper, an energy harvesting circuit is designed and simulated using Advanced Design System (ADS) which is compatible with 5G technology. A microstrip patch antenna with −17.35 dB return loss at 11.02 GHz is designed and implemented. A rectifier using a Schottky diode is also designed to operate at high frequencies. Simulation results indicate that the proposed solution can extract energy from incoming waves at 11.02 GHz and generate 1.18 V across an IoT sensor with an efficiency of 87%.

Discharge voltage of insulation is pivotal in the design of High Voltage systems. In this work, a machine learning algorithm is used to develop a model to predict the discharge characteristics of air. Finite Element Method (FEM) simulations have been performed to extract different electric field and energy features of air gaps in the range 5mm-40mm under lightning impulses of positive polarity. While developing the model, these features along with gap lengths are considered. The features have been used for training a machine learning algorithm based on Gaussian Process Regression (GPR) to develop the model. The results obtained from the model are validated with measured experimental data. A good comparison between the predicted data and the measured data establishes the accuracy of the predicted model. The proposed methodology is compared using different kernel functions.

In this work, a non-magnetic RF balun is implemented for 3 T magnetic resonance imaging (MRI) scanners operating at 128 MHz to transform a balanced input signal from a dipole or loop antenna into an unbalanced output signal. It is fabricated on a low-cost, copper cladded four-layer printed circuit board (PCB), FR4 with a thickness of 1.57 mm and a copper thickness of 35 µm, with overall footprint of 11.6 mm × 12.2 mm. A comparison among the ADS RF momentum simulations and the measured results indicates a good agreement with the measured insertion and return losses of better than −1 dB and −13 dB, respectively, in a 50 Ω termination setting.

Live RF Image Transmission using OFDM with RPi and PlutoSDR 使用带有RPi和PlutoSDR的OFDM实时射频图像传输

Orthogonal frequency-division multiplexing (OFDM) is a multi-carrier digital communication technique which addresses digital communication problems like intersymbol interference (ISI), low data rates, and inter-carrier interference (ICI). It uses multiple low data rate carriers to assemble a high data rate communication system. Each low data rate carrier has enough long symbol periods which then eliminates ISI. Orthogonality allows each carrier frequency to be closely spaced, although overlapped, without ICI. The contribution of this paper is to show that real-time OFDM RF communications is possible and assess its performance. This was achieved by integrating several embedded platforms: a light-weight processor, web camera, and software define radio using the Mathworks MATLAB environment. This is an efficient way to transmit live images or video feeds for monitoring and surveillance purposes. The work focused on transmitting live images at a constant rate from the web camera to the software defined radio, which relayed it to another software defined radio at a remote location.
正交频分复用(OFDM)是一种多载波数字通信技术,它解决了数字通信中诸如码间干扰(ISI)、低数据速率和载波间干扰(ICI)等问题。它使用多个低数据速率的载波组成一个高数据速率的通信系统。每个低数据速率载波具有足够长的符号周期,从而消除ISI。正交性允许每个载波频率虽然重叠,但间隔很近,没有ICI。本文的贡献是表明实时OFDM射频通信是可能的,并评估其性能。这是通过集成几个嵌入式平台实现的:轻量级处理器、网络摄像头和使用Mathworks MATLAB环境的软件定义无线电。这是一种传输实时图像或视频馈送的有效方式,用于监视和监视目的。这项工作的重点是将实时图像以恒定的速率从网络摄像机传输到软件无线电,软件无线电将其转发到远程位置的另一个软件无线电。

The existing Adaptive Notch Filter (ANF)-based frequency estimation methods have problems of slow convergence speed, unstable error and limited selection of iterative initial values. In this paper, a frequency estimation method based on the indirect average plain gradient algorithm is proposed. It uses a new error function applied to the second-order adaptive Infinite Impulse Response (IIR) notch filter. The proposed error function is the mean value of the weighted average of the squares of the two signals outputted by Finite Impulse Response (FIR) and IIR sections of the ANF. It has better gradient characteristics, and arbitrary initial value can be selected for the following iterative calculation. The theory and simulation show that the proposed algorithm, compared with other indirect gradient algorithm, improves the convergence speed and estimation accuracy with little addition of the computation, while it is superior in varying-frequency signal tracking performance.
现有的基于自适应陷波滤波器(ANF)的频率估计方法存在收敛速度慢、误差不稳定以及迭代初值选择有限等问题。本文提出了一种基于间接平均平面梯度算法的频率估计方法。它采用一种新的误差函数应用于二阶自适应无限脉冲响应陷波滤波器。所提出的误差函数是由有限脉冲响应(FIR)和有限脉冲响应(IIR)部分输出的两个信号的平方加权平均值的平均值。它具有较好的梯度特性,可以选择任意初始值进行后续迭代计算。理论和仿真结果表明,与其他间接梯度算法相比,该算法在不增加计算量的情况下提高了收敛速度和估计精度,同时具有较好的变频信号跟踪性能。
