MODELING AND SIMULATION METHODS MATRIX
The most commonly used methods used for modeling and simulation of circuits and
systems are Vector Fitting (VF) and Spice respectively. The popularity of VF is mainly
due to its compatibility with a well known commercial tool like Spice. This one-way
solution shows several limitations, mainly due to the origin the tool, conceived initially
for the design of Integrated Circuit where the effect of signal propagation can be
neglected in most applications and the circuit can be described by Ordinary Differential
Equations (ODE). This limitation is the main reason why more than thirty years ago both
DWS and PWLFIT were developed as industrial products having wideband circuits and
systems as targets [3]. The recent development of the automated version of
PWLFIT[1,2,4] opens the door also to hybrid PWL/VF[5,8,9] methods. This further
possibility expands up to six the number of possible alternatives to modeling and
simulation methods. These alternatives can be represented as elements of a 2X3 matrix
(Fig. 1) where for each cell the main features of the related method are summarized.

The feasibility of such alterative methods has been already demonstrated in some pilot
applications [5,8,9,10].
In particular the Hybrid method, where PWLFIT and VF are applied to separated time-
domain windows of the same response under analysis, can be applied to both
simulators to overcome the limitations of a method alone.
Experimental comparative analysis of the two main alternatives Spice/VF and
DWS/PWLFIT are shown in [6,7].

in this paper, a novel harmonic modeling technique by utilizing the concept of multi -terminal components is presented and applied to frequency scan analysis in multiphase distribution system. The proposed modeling technique is based on gathering the same phase busses and elements as a separate group (phase grouping technique, PGT) and uses multi-terminal components to model three-phase distribution system. Using multi-terminal component and PGT, distribution system elements, particularly, lines and transformers can effectively be modeled even in harmonic domain. The proposed modeling technique is applied to a test system for frequency scan analysis in order to show the frequency response of the test system in single and three-phase conditions. Consequently, the effects of mutual coupling and transformer connection types on three-phase frequency scan responses are analyzed for symmetrical and asymmetrical line configurations.

Analysis of Impact of Graph Theory in Computer Application

IRJET Journal

At the present time whole information and communication technology industry contributes to the global carbon emission. With the aim of reducing the carbon footprint and the operating cost of wireless networks, overall energy reduction is required in the region of two to three orders of magnitude. Meanwhile, significant increase of the network spectrum efficiency is needed to cope with the exponentially increasing traffic loads. Due to this factors spatial modulation (SM) has recently established itself as promising transmission concept which belongs to single-radio frequency large scale multiple input multiple output (MIMO) wireless system. Spatial modulation MIMO takes advantage of whole antenna array at the transmitter, while using limited number of radio frequency chains. The multiple input multiple output multiplies capacity by transmitting different signals over multiple antennas and orthogonal frequency division multiplexing (OFDM), which divides a radio channel into many closely spaced sub channels to provide more reliable communication at high speeds. The system calculate the bit error rate (BER) for multicast multiple input multiple output system with the spatial modulation (SM) and study the effect of signal to noise ratio on bit error rate. MATLAB software is use to simulate system. The simulation results show that bit error rate decreases as signal to noise ratio increases. System reaches zero bit error rate for the value of signal to noise ratio greater than 18dB. System has provided less bit error rate for large signal to noise ratio which improves system performance.

Jamming aware traffic allocation for multiple-path routing using portfolio se...

Saad Bare

Multiple-path source routing protocols allow a data source node to distribute the total traffic among available paths. we consider the problem of jamming-aware source routing in which the source node performs traffic allocation based on empirical jamming statistics at individual network nodes. We formulate this traffic allocation as a lossy network flow optimization problem using portfolio selection theory from financial statistics. We show that in multisource networks, this centralized optimization problem can be solved using a distributed algorithm based on decomposition in network utility maximization (NUM). We demonstrate the network's ability to estimate the impact of jamming and incorporate these estimates into the traffic allocation problem. Finally, we simulate the achievable throughput using our proposed traffic allocation method in several scenarios.

Analysis of Hill Road Network Structure in Developing Countries

IJRTEMJOURNAL

The purpose of this paper is to identify the critical road links and intersections in a road network which have a great influence on the road network. A framework of road network structure measurement model is proposed. The node importance number and the link importance number are introduced in this model to define road network structure. Using this model, the critical components of the road network can be identified. Then, necessary interventions in a road network can be designed to improve its structure either adding a new link/s or upgrading the properties of the existing link/s or node/s (e.g. geometry, safety, capacity). The road network of the hill town of Tansen in Nepal is analyzed by using this model. The network structure measurement method proposed in this paper can be generalized to hill road network in developing countries

Automated Piecewise-Linear Fitting of S-Parameters step-response (PWLFIT) for...

Piero Belforte

An innovative full time-domain macromodeling technique for general, linear multiport systems is described. The methodology is defined in a digital wave framework and timedomain simulations are performed via an efficient method called Segment Fast Convolution (SFC). It is based on a piecewiseconstant (PWC) model of the impulse response of scattering parameters, computed starting from a piecewise-linear fitting of their step response (PWLFIT). Such step response is directly available from time-domain reflectometer measurements (TDR/TDT) or equivalent simulations. The model-building phase is performed in a fast automated framework and an analytic formulation of computational efficiency of the SFC with respect to the standard time-domain convolution is given. Two application examples are used to verify the PWLFIT performance and to perform a comparison with macromodeling methods defined in the frequency-domain, such as Vector Fitting (VF). Index Terms—Digital wave models, time-domain macromodeling, S-parameters, step response.

VECTOR VS PIECEWISE-LINEAR FITTING FOR SIGNAL AND POWER INTEGRITY SIMULATION

Piero Belforte

The basic concepts of two fitting methods suitable for signal and power integrity simulation up to multi-gigabit/sec rates are presented. The traditional method is based on Vector Fitting (VF), a well known technique to approximate complex functions of frequency by a rational polynomial expression in terms of poles and residues. The second is a full time-domain approach mainly based on behavioral models supported by the Digital Wave Simulator. PWLFIT/DWS advantages over VECTFIT/Spice can be summarized with the 3S acronym: SIMPLICITY, STABILITY and SPEED. SIMPLICITY because the pwl fitting of a time-domain behavior is a very fast, explicit and intuitive process that doens't need the solution of implicit equations as required by Vector fitting. Time-domain S-parameter of actual devices in matched conditions shows simpler behaviors than the corresponding impedance in the frequency domain. STABILITY because the use of Digital Wave processing is intrinsically very stable. Extracted pwl behaviors processed by fast convolution within DWS are unconditionally stable if the source behavior is stable. This means that NO numerical conditioning is required. As known Vector Fitting often require numerical conditioning to get stable results. SPEED: time-domain pwl fitting is a very fast process. DWS simulations are also very fast even at very small time steps required by multigigabit system analysis. DWS/SPICE typical speedups are 100X for traditional VF derived RLC-TL circuits and up to 10000X when using pwl Behavioral Models in time domain.

Digital Wave Simulation of Lossy Lines for Multi-Gigabit Applications

Piero Belforte

Frequency domain Vector Fitting (VF) is a well known technique to generate circuital models of a spatially discretized lossy transmission lines from theoretical formulation of losses. The sub-picosecond time steps required by multi-gigahertz bandwidths and short transmission lines included in the models, determine long Spice simulation times. A 100X speedup can be gained using the Digital Wave Simulator (DWS) instead of Spice. DWS processes the waves of a Digital Network built up connecting together scattering blocks (circuit elements, nodes and S-parameter multi-ports) coming from a Spice-like description. Being a DSP wave processor instead of a classical nodal equations solver, DWS is computationally very fast and numerically stable. Comparisons with commercial simulators like Microcap11 and CST Cable Studio show a good matching of results. A further 10-100X simulation speedup is obtained if Piecewise-Linear Fitting (PWLF) is used to describe the time-domain behaviors of Scattering Parameters. Single or multiple cell Behavioral Time Models (BTM) can be extracted by PWLF from TDR/TDT measurements and processed by DWS fast convolution algorithms. A setup de-embedding can be performed by pwl breakpoints optimization to fit actual measurements. A RG58 coaxial cable is analyzed and its VF-derived eye-diagrams are compared to PWLF measurement-derived results. At multi-gigabit rates significant differences, due to cable physical implementation effects, are observed. The modeling/simulation alternatives (VF/Spice, VF/DWS and PWLF/DWS) are compared together and the advantages of PWLF/DWS in term of simplicity, stability and speed are highlighted.

Multigigabit modeling of hi safe+ flying probe fp011

Piero Belforte

This document describes the modeling methodology used to assess the performance of these probes in terms of allowed digital bandwidth of signals chosen for temporary fault insertion trials. This methodology is based on time-domain characterization of Scattering parameters (TDR/TDT) and subsequent extraction of a Behavioral Time-domain Model (BTM) [13] of the probe itself. This technique called PWLFIT (Piece-Wise Linear FITting) [14] [15]is supported by the Digital Wave Simulator DWS [16] [17] and its companion tool DWV [18] developed starting in the early '90s for very fast modeling and simulation of high-speed circuits and systems.

5G Coupler Design for Intelligent Transportation System (ITS) Application

IJECEIAES

Aiming to achieve 3-dB coupling, operating in fifth generation (5G) technologies, this paper introduces a new design of tight coupling coupler that will be operated in 5G technologies. Two stubs and two slots have been implemented into the 3-dB coupler design in order to achieve impedance matching between the ports and to give better coupling performances, respectively. Moreover, a study on the stubs’ and slots’ effects towards the S31 of the 3-dB coupler has also been presented in this paper. The proposed coupler is designed on Rogers RO4003C substrate. The simulation results and the analytical study on the stubs and slots implementation show that both stubs and slots affect the performance of the coupling coefficient.

Beamforming for millimetre-wave (mmWave) frequencies has been studied for many years. It is considered as an important enabling technology for communications in these high-frequency ranges and it received a lot of attention in the research community. The special characteristics of the mmWave band made the beamforming problem a challenging one because it depends on many environmental and operational factors. These challenges made any model-based architecture fit only special applications, working scenarios, and specific environment geometry. All these reasons increased the need for more general machine learning based beamforming systems that can work in different environments and conditions. This increased the need for an extended adjustable dataset that can serve as a tool for any machine learning technique to build an efficient beamforming architecture. Deep MIMO dataset has been used in many architectures and designs and has proved its benefits and flexibility to fit in many cases. In this paper, we study the extension of collaborative beamforming that includes many cooperating base stations by studying the impact of User Equipment (UE) speed ranges on the beamforming performance, optimizing the parameters of the neural network architecture of the beamforming design, and suggesting the optimal design that gives the best performance for as a small dataset as possible. Suggested architecture can achieve the same performance achieved before with up to 33% reduction in the dataset size used to train the system which provides a huge reduction in the data collection and processing time.

IJECEIAES

In recent years, the wireless spectrum has become increasingly scarce as demand for wireless services has grown, requiring imaginative approaches to increase capacity within a limited spectral resource. This article proposes a new method that combines modified symbol time compression with orthogonal frequency division multiplexing (MSTC-OFDM), to enhance capacity for the narrow-band internet of things (NB-IoT) system. The suggested method, MSTC-OFDM, is based on the modified symbol time compression (MSTC) technique. The MSTC is a compressed waveform technique that increases capacity by compressing the occupied symbol time without losing bit error rate (BER) performance or data throughput. A comparative analysis is provided between the traditional orthogonal frequency division multiplexing (OFDM) system and the MSTC-OFDM method. The simulation results show that the MSTC-OFDM scheme drastically decreases the symbol time (ST) by 75% compared to a standard OFDM system. As a result, the MSTC-OFDM system offers four times the bit rate of a typical OFDM system using the same bandwidth and modulation but with a little increase in complexity. Moreover, compared to an OFDM system with 16 quadrature amplitude modulation (16QAM-OFDM), the MSTC-OFDM system reduces the signal-to-noise ratio (SNR) by 3.9 dB to transmit the same amount of data.

Digital Wave Simulation of Quasi-Static Partial Element Equivalent Circuit Me...

Piero Belforte

This is an extended version of the paper published on IEEE Transactions on EMC, October 2016. PEEC modeling is a well established technique for obtaining a circuit equivalent for an electromagnetic problem. The time domain solution of such models is usually performed using nodal voltages and branch currents, or sometimes charge and currents. The present paper describes a possible alternative approach which can be obtained expressing and solving the problem in the waves domain. The digital wave theory is used to find an equivalent representation of the PEEC circuit in the wave domain. Through a pertinent continuous to discrete time transformation, the constitutive relations for partial inductances, capacitances and resistances are translated in an explicit form. The combination of such equations with Kirchhoff laws allows to achieve a semi-explicit resolution scheme. Three different physical configurations are analyzed and their extracted Digital Wave PEEC models are simulated at growing sizes using the general-purpose Digital Wave Simulator (DWS). The results are compared to those obtained by using standard SPICE simulators in both linear and nonlinear cases. When the size of the model is manageable by SPICE, an excellent accuracy and a speed-up factor of up to three orders of magnitude are observed with much lower memory requirements. PEEC model sizes manageable by DWS are also an order of magnitude larger than SPICE. A comparative analysis of results including the effect of parameters like the simulation time step choice is also presented.

Interoperator Dynamic Spectrum Sharing (Analysis, Costs and Implications)

CSCJournals

This paper addresses Dynamic Spectrum Sharing (DSS) between two wireless operators. The Universal Mobile Telecommunication System (UMTS) network is used as a case study. The proposed protocol is evaluated under the uniform and non-uniform traffic conditions. The underlying principles of the algorithm can be deployed in the UMTS extension Band (2500MHz-2690MHz) which is yet to be allocated or the re-farmed GSM spectrum (900MHz/1800MHz). The simulation results for the proposed protocol shows that significant spectrum sharing gains can be obtained. However such spectrum efficiency gain need to be carefully balanced with the complexity in terms of latency (delays) and additional overhead it brings to the network. The results show that significant spectrum sharing gain of 4.0 % and 2.0 % can be obtained under uniform and non-uniform traffic conditions

A NOVEL ROBUST AND LOW-COMPLEXITY SPACETIME CODES FOR INDUSTRY 4.0 SYSTEMS

ijwmn

This paper proposes different robust and low-complexity space time codes which provide more reliability for industrial automation. An innovative synchronized uplink system configuration for an Industrial Environment is proposed. Mathematical framework for estimating the channel phase of each Slave Node (SN) is developed. Furthermore, the channel is practically estimated based on an innovative method using parallel sequence spread spectrum (PSSS) implemented in Universal Software Radio Peripheral (USRP). The proposed space time codes are applied in the uplink of an industrial communication system where the channel is modelled using Quasi Deterministic Radio Channel Generator (Quadriga) which follows a geometry-based stochastic approach. Simulation results exposed that the proposed codes surpass Alamouti code for Industrial Automation. The bit error rate (BER) performance demonstrates that the achieved coding gain for the proposed codes is higher than Alamouti code leading to more robust communication. Furthermore, a low complexity decoders based on minimum mean squared error (MMSE) and zero forcing (ZF) algorithms are designed at the receiver side. The proposed codes give a predominant execution against the state-of-the-art space time codes for Industry 4.0.

A parallel-plate capacitor implemented by a rectangular double-sided printed circuit board is characterized by means a stimulus signal injected at a corner. Both frequency-domain (VNA) and time-domain (TDR) techniques are utilized to determine the step response of the reflected wave (S11) to be compared to the theoretical behavior of the equivalent parallel plate capacitance. A commercial application is utilized to convert the frequency domain tabulated data of the frequency response into the corresponding TDR response. A very accurate and fast 2D TLM (Transmission Line Model) model can be easily extracted from these single time-domain experimental responses.

An Approach to Detecting Writing Styles Based on Clustering Techniques

ambekarshweta25

An Approach to Detecting Writing Styles Based on Clustering Techniques Authors: -Devkinandan Jagtap -Shweta Ambekar -Harshit Singh -Nakul Sharma (Assistant Professor) Institution: VIIT Pune, India Abstract: This paper proposes a system to differentiate between human-generated and AI-generated texts using stylometric analysis. The system analyzes text files and classifies writing styles by employing various clustering algorithms, such as k-means, k-means++, hierarchical, and DBSCAN. The effectiveness of these algorithms is measured using silhouette scores. The system successfully identifies distinct writing styles within documents, demonstrating its potential for plagiarism detection. Introduction: Stylometry, the study of linguistic and structural features in texts, is used for tasks like plagiarism detection, genre separation, and author verification. This paper leverages stylometric analysis to identify different writing styles and improve plagiarism detection methods. Methodology: The system includes data collection, preprocessing, feature extraction, dimensional reduction, machine learning models for clustering, and performance comparison using silhouette scores. Feature extraction focuses on lexical features, vocabulary richness, and readability scores. The study uses a small dataset of texts from various authors and employs algorithms like k-means, k-means++, hierarchical clustering, and DBSCAN for clustering. Results: Experiments show that the system effectively identifies writing styles, with silhouette scores indicating reasonable to strong clustering when k=2. As the number of clusters increases, the silhouette scores decrease, indicating a drop in accuracy. K-means and k-means++ perform similarly, while hierarchical clustering is less optimized. Conclusion and Future Work: The system works well for distinguishing writing styles with two clusters but becomes less accurate as the number of clusters increases. Future research could focus on adding more parameters and optimizing the methodology to improve accuracy with higher cluster values. This system can enhance existing plagiarism detection tools, especially in academic settings.

Hierarchical Digital Twin of a Naval Power System

Kerry Sado

A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Simulation-modeling matrix

1. Piero Belforte MODELING AND SIMULATION METHODS MATRIX May 5 2021 1 MODELING AND SIMULATION METHODS MATRIX The most commonly used methods used for modeling and simulation of circuits and systems are Vector Fitting (VF) and Spice respectively. The popularity of VF is mainly due to its compatibility with a well known commercial tool like Spice. This one-way solution shows several limitations, mainly due to the origin the tool, conceived initially for the design of Integrated Circuit where the effect of signal propagation can be neglected in most applications and the circuit can be described by Ordinary Differential Equations (ODE). This limitation is the main reason why more than thirty years ago both DWS and PWLFIT were developed as industrial products having wideband circuits and systems as targets [3]. The recent development of the automated version of PWLFIT[1,2,4] opens the door also to hybrid PWL/VF[5,8,9] methods. This further possibility expands up to six the number of possible alternatives to modeling and simulation methods. These alternatives can be represented as elements of a 2X3 matrix (Fig. 1) where for each cell the main features of the related method are summarized. Figure 1

2. Piero Belforte MODELING AND SIMULATION METHODS MATRIX May 5 2021 2 The feasibility of such alterative methods has been already demonstrated in some pilot applications [5,8,9,10]. In particular the Hybrid method, where PWLFIT and VF are applied to separated time- domain windows of the same response under analysis, can be applied to both simulators to overcome the limitations of a method alone. Experimental comparative analysis of the two main alternatives Spice/VF and DWS/PWLFIT are shown in [6,7].
