Connection and routing parameters of wireless sensor networks are considered for static topologies and uniform distribution of nodes. Most of the studied models do not take into account the parameters of message connectivity and their delivery time between unevenly distributed nodes. in the proposed study, models of connectivity analysis and message delivery between unevenly distributed nodes are developed. Models of wireless sensor networks with uniform and normal distribution of nodes and research on the network connectivity parameter for these models are proposed. Network models with different types of distributions are built based on the Erdosh-Rani random graph model, which allows describing of the connectivity of wireless sensor networks as the connectivity of a random graph, that is, to determine the connectivity of wireless sensor networks with the probability of finding the distance between two vertices of the graph. simulation models with a uniform and normal distribution of nodes are implemented to investigate the probability of network connection. The choice of these types of distribution is explained by possible real distributions of nodes in the studied area.

For high resolution SAR ADC, the noise and distortion will significantly degrade the performance, thus should be considered carefully during design. This paper presents a behavioral modeling of SAR ADC in Simulink. The model includes the performance limitations such as clock jitter, capacitor mismatch, sampled KT/C noise for switches, noise and offset of comparator and S/H on-resistance distortion. The simulation results of the proposed model provide guidance in choosing the circuit structure and determine spec breakdown of each block in the SAR ADC, which increases the design efficiency with fast design iterations. © 2023 IEEE.

The challenge of predicting the reliability of solder joints in high-power LED packages by Finite Element Analysis (FEA) is crucial for the automotive industry. Focusing on the thermo-mechanical stresses between LED package and the PCB, *** aluminum insulated metal substrate (Al-IMS), this paper analyzes the crack formation in the solder joints for seven different ceramic-based LED packages. The model is validated by data from a large experimental study, covering typical two pad and three pad footprint design for LED package and five solder materials. The data set contains experimental data of nearly 1,800 LED packages, including over 40,000 Transient Thermal analyses (TTA) and 9,000 Scanning Acoustic Microscopy (SAM) measurements. The paper investigates different post-processing approaches related to FEA simulations for surfacemounted devices (SMD) LED assemblies, recognizing the limitations of approaches used for Ball Grid Array (BGA) packages due to the large difference in geometry and pad layout. The primary goal of the FEA model is to correctly predict the reliability of different pad designs, *** or three pad footprints for different solders and develop the universal lifetime model. The methodology includes detailed thermomechanical simulations via Ansys. The paper compares the behavior of SAC305 and SAC105. Each LED package undergoes five thermal cycles, ranging from-40 °C to 125 °C, to assess accumulated creep strain. The Coffin Manson model is utilized for the lifetime prediction of the solder joint. To the best of the author s knowledge, the paper presents for the first time a model which is validated for different pad designs and answers the question: Is a threepad or a two-pad preferable for solder joint reliability? The results show a good agreement, i.e. R 2=96% for critical path averaging, of simulation outcomes for ceramic LED packages with thick film metallization. However, some variability is noted for ceramic LED packages with thin film ce

This paper proposes a globally optimized behavioral modeling algorithm using cascaded feed-forward neural network in conjugation with Particle Swarm optimization (PSO) for fully printed VO2 based RF switches. The proposed model makes use of varied set of operating conditions (geometric dimensions and operating temperature) over a frequency range of 0.01 to 33 GHz. The modeling algorithm enables flexibility in selecting the optimized hyperparameters such as number of neurons in each hidden layer, and activation function at each layer. The developed model is tested for both interpolation and frequency extrapolation cases up to 40 GHz to establish the validity and robustness of the modeling algorithm. An excellent agreement between the measured and the modeled performance over a broad frequency range demonstrates a good generalization capability and successful model development strategy. The proposed model is then evaluated within a commercial circuit simulator (Keysight's ADS) to demonstrate usefulness in RF circuit design. © 2023 IEEE.

Epoxy resins are widely used in molding electrical insulators and electronic components due to their superior dielectric properties and mechanical strength. However, due to poor process control along with the complex geometry of their components, parts can entail air pockets, cracks, or deformations driven by residual stresses. To address these challenges, this research uses the Computational Fluid Dynamics (CFD) software Autodesk Moldflow Synergy 2023 to visualize epoxy resin flow behavior and predict the curing behavior as it flows through the mold using respective models. When simulating the mold-filling behavior, comprehensive thermo-mechanical data are required for both uncured and cured states of cycloaliphatic epoxy resins. Therefore, it was crucial to thoroughly characterize the material to obtain precise material parameters for using them in simulations, as these parameters play a vital role in the accuracy of the simulations. Python-based formulations of the Prout-Tompkins cure kinetic and Cross-Castro-Macosko viscosity models are used to comprehensively analyze the flow front and curing behavior during an Automatic Pressure Gelation (APG) process. This research provides valuable insights into the behavior of epoxy resin when molded in complex scenarios. It enables the design of optimized molds while allowing for fast and efficient evaluation and optimization of process parameters, ultimately reducing high rejection rates as safety critical parts, like insulators, need to be flawless. © 2024 IEEE.

For the first time, the electrothermal characteristics of the stacked 2T0C memory array were modeled based on the material properties, electron transport mechanism of InGaZnO4 (IGZO) and basic Fourier heat flow equation utilizing the technology computer-aided design (TCAD) tool. According to the proposed electrothermal model, the multi-layer stacked 2T0C memory array would bring severe self-heating issue from the thermal crosstalk among layers. The temperature rising of stacked 2T0C cells decrease the retention time severely due to the temperature instability of IGZO thin-film transistors TFTs. Furthermore, several advanced device-level strategies were proposed to ameliorate the heat accumulation problem.

With the development of communication technology, the performance of digital-to-analog converters as the last link in signal processing is particularly important. This paper analyzes the errors of current rudder DAC and their effect on DAC performance. Different compensation methods are proposed to compensate for or eliminate the errors. Through system modeling, it is concluded that under the conditions of static parameters DNL90dB and SNDR>70dB, the random matching error should be less than 0.001, the gradient error less than 1E-5 and the admittance rate less than 1E-7. The correctness of the theoretical analysis can be verified through system modeling and simulation, providing accurate guidance direction for circuit design and greatly shortening the design cycle. © Published under licence by IOP Publishing Ltd.
