Terrestrial sensor systems and platforms regularly rely on photovoltaic cells as their primary power source. With a rechargeable battery backup, solar modules provide these remote sensor systems with reliable, simple, and predictable power. For these terrestrial systems, power predictions are well established and engineers developing power budgets have multiple avenues for estimating daily average...
The development of renewable energy technologies is an inevitable requirement to cope with environmental, economic and political challenges. Solar energy is regarded as one of the most promising types among renewable energy sources. So, the characterization of solar parameters is a significant process in solar energy installations. In this paper, we use three different curve fitting methods called...

It was approbation of suggested approach for the region.
RF CMOS technology provides a platform for the production of analog, digital and RF circuits on a single chip for futuristic high-level integration. This facilitates the need for a robust compact model for RF FinFETs to study the circuits in a precise and convenient way. In this paper, we have characterized 14-nm N-channel bulk FinFETs by performing two-port S-parameter measurements. Further, BSIM-CMG...
In order to study the charging characteristics of aerospace dielectric materials and analyze the influence of the material thickness on the equilibrium potential and the charging time, the differential equation of the surface potential is obtained.

Present and future link (SerDes) design requires a strong and effective coupling between high-speed circuit design, optimization, and digital communications, its problems are different that new solutions are required. This paper proposed an analytical wireline channel model for path loss prediction for effective electronic circuits and systems design. Proposed model closely match experimental data...
A new method of constructing nonparametric dynamic model of the human oculomotor system on the basis of experimental data “input-output” is developed, considering nonlinear and inertial properties of the rectus muscles of the eye. A technology for tracking eye movement is based on the videos. It is possible to determine the dynamic characteristics of the oculomotor system functions as a transition...
Modeling and Simulation (M&S) has become an essential tool in the development, testing and verification of operational software in a complex multi-domain, multi-threaded heterogeneous system of systems environment. The complex systems of today encompass mix of hardware sub-systems (with varying degree of capabilities), software environments (comprising a plethora of development environments, operating...
Modeling helps explain the fundamental physics hidden behind experimental data. In the case of material modeling, running one simulation rarely results in output that reproduces the experimental data. Often one or more of the force field parameters are not precisely known and must be optimized for the output to match that of the experiment. Since the simulations require high performance computing...
Batch and stream processing represent the two main approaches implemented by big data systems such as Apache Spark and Apache Flink. Although only stream applications are intended to satisfy real-time requirements, both approaches are required to meet certain response time constraints. In addition, cluster architectures continuously expand and computing resources constitute high investments and expenses...
In this research, we try to model soot dynamics in a gasoline engine by using measurement data.

The constructed soot model will be utilized for further developing and improving transient injection control.
Public safety has been discussed for many years, but how to use and understand crime data is still difficult. Limitations of previous research were mainly restricted by technology. The significant technological advance since last century provided a tool for researchers to compute large amount of data and complicate models while shrinking process time too. This research tried to combine results from...
Decision tree model is one of data mining method for builds classification models in the form of a tree structure. These methods are produced various ways of splitting a data set into branch like segments that call nodes. Today, forecasting method is very importance for every side especially agriculture. Because some farmers who want to predict their crops for each semester. This paper describes about...
Data acquisition systems for large-scale high-energy physics experiments have to handle hundreds of gigabytes per second of data, and are typically implemented as specialized data centers that connect a very large number of front-end electronics devices to an event detection and storage system. The design of such systems is often based on many assumptions, small-scale experiments and a substantial...
The visual simulation system which the docking process of replenishment at sea is constructed based on MultiGen Creator and Vega Prime. In a bid to modeling and driving of the visual simulation, a large number of the real-time data should be transformed for simulation in which the entire process of replenishment at sea. According to the complicated power and movement state of the docking mechanism...
Solving inverse problems is central in geosciences and remote sensing. Very often a mechanistic physical model of the system exists that solves the forward problem. Inverting the implied radiative transfer model (RTM) equations numerically implies, however, challenging and computationally demanding problems. Statistical models tackle the inverse problem and predict the biophysical parameter of interest...
The Eclipse Modeling Framework (EMF) is the official Eclipse modeling framework. It provides code generation facilities for building tools and applications based on structured data models.
