In many networked embedded systems, crucial factors for correct functionality are the network’s real-time capability, determinism, and reliability. Besides these requirements, a high network performance in terms of throughput and latency is desired. One of the applied techniques to improve performance is cut-through communication. It allows to forward messages as soon as the packet header is pr...

We present a phase shift datuming and migration algorithm for the data acquired on a nonnat surface. First of all, we formulate the exploding reeector modeling scheme for a nonnat recording surface. Then, the migration scheme is found as the conjugate operator of the modeling operator. In order to get the correct migration and datuming operators, the forward modeling must be physically reasonab...

Nowadays, Hidden Markov models are extensively utilized for modeling stochastic processes. These models help researchers establish and implement the desired theoretical foundations using Markov algorithms such as Forward one. however, Using Stability hypothesis and the mean statistic for determining the values of Markov functions on unstable statistical data set has led to a significant reducti...

the present article investigates the application of high order tsk (takagi sugeno kang) fuzzy systems in modeling photo voltaic (pv) cell characteristics. a method has been introduced for training second order tsk fuzzy systems using anfis (artificial neural fuzzy inference system) training method. it is clear that higher order tsk fuzzy systems are more precise approximators while they cover n...

This paper presents a full-wave, whole-system modeling of Microwave Imaging Tomography (MWT) systems, to be used as forward model in reconstruction (inverse) algorithms. The full geometry including antennas and their ports is simulated via a Finite Element Method (FEM) approach. A new technique is used to compute the antenna operation in the system, which provides a general method to enforce th...

Modeling data via artificial neural networks (ANN) is not a new concept. Most of the underlying techniques have been known since the 1940s. It has to be pointed out though that a series of recent advances in how the networks are trained and utilized form the foundation of today's Deep Learning ecosystem. It is a fair statement that the recent advances brought forward by Deep Learning reflect a ...
