Internal model control (IMC) offers an intuitive control structure and simple tuning philosophy, which makes it appealing to industrial applications. In our recent work [1], we proposed composite adaptive IMC (CAIMC) which simultaneously identified the model and the inverse in the IMC structure. It demonstrates good performance and auto-tuning capability in simulations and experiments. In this paper,...
The regression analysis is a considerable statistical instrument applied in many sciences. The ordinary least squares is a conventional method used by Regression Analysis. In regression analysis, the least squares ratio method outperforms than the ordinary least squares method, especially in case of the presence of outliers. This paper includes a novel approach to M-estimators, named the weighted...
This paper presents the analysis of the modeling error of an approximate model in a Static Light Scattering (SLS) problem for the morphological characterization of particle systems through the estimation of the Particle Size Distribution (PSD). The modelling error of the employed approximate model called the Local Monodisperse Approximation (LMA) is obtained by means of processing simulated data generated...
In wireless fading channels, the path-loss exponent (PLE) is one of the most fundamental parameters to characterize the channel propagation. It has an important impact on the received signal strength (RSS)-based localization in wireless sensor networks (WSN). On the other hand, the communication range of a sensor in a WSN depends on the transmission power and on the environment (outdoor or indoor)...
This paper is devoted to the description of software for statistical analysis of lifetime data. Software “LiTiS” allows constructing parametric and semiparametric accelerating life testing models with right censored and left truncated data. The overview of main parts of user interface and some properties of the software are presented in the paper.
Spark has grown both in popularity and complexity in recent years. In order to use available resources in an efficient way, users need to understand how the behavior of their applications is affected by the size of the datasets and various configuration settings. Indeed, Spark allows users to specify many configuration parameters and understanding the impact of these choices with respect to the application...
This paper proposes a novel and highly scalable multistage packet-switch design based on Networks-on-Chip (NoC). In particular, we describe a three-stage Clos packet-switch fabric with a Round-Robin packets dispatching scheme where each central stage module is an Output-Queued Unidirectional NoC (OQ-UDN), instead of the conventional single-hop crossbar. We test the switch performance under different...
The analytical expressions for trapezoidal and triangular signals arbitrary order q integral factors of harmonics are obtained by using the infinite series harmonic synthesis formulae. Since the only first order coefficient of the differential factors of harmonics can be calculated this way for these signals, the before offered LabVIEW virtual instrument is modified for the up to third order integral...
As the speed metric of Massively Parallel Multi-Processors System-on-Chip (MP2SoC) systems has increased over time, another metric has become more important: power consumption. Finding a tradeoff between power consumption and performance early in the design flow of MP2SoC systems in order to satisfy time-to-market is the design challenge of Electronic Design Automation (EDA) tools. This paper presents...
The propose of this study aims to use eyeball model approach and algebra-geometric to analyze 3-D gaze estimation. Which stereo gaze directions calculate from 3-D coordinates of the value of Cornea Center and Pupil Center of left and right eyes. Then stereo gaze directions are used to get point of gaze (POG) of 3-D coordination. The experimental is designed in three conditions, (i) no head movement...
Graphical models and the corresponding linear structural equation model can be used as a mathematical language for describing a causal-effect relationship. A common problem is argued about which covariates in the diagram should be used to estimate the causal effects. The primary aim of this paper is to show different covariates selection for estimating the causal effects and we evaluated the asymptotic...
This article is devoted to the information reliability of radar systems. Main attention focuses on the radar system human-operator reliability, and to factors that decrease it. The possibilities of it level increase by the introduction of redundancy are explored. Optimal levels of redundancy for the radar system human-operator reliability are defined.
Computer based simulation technology remains one of the most popular approaches in the research field. It has the advantages with comparison to analytical methods for some applications. However, it requires implementing procedures devoted to the determination of developing simulation model's parameters in order to provide better performance and accuracy of the results. In the paper, the developed...
Energy consumption is a major problem in Wireless Sensor Networks (WSNs) since in most scenarios nodes operate on batteries with reduced size and low capacity. Battery lifetime estimation is therefore crucial to evaluate the network behavior over time. In addition, battery lifetime estimation is a major challenge since it depends on many factors, such as the duty cycle of supported applications and...
In this paper, we study the performance of hybrid cognitive radio systems that combine the benefits of interweave and underlay systems by employing a spectrum sensing and a power control mechanism at the Secondary Transmitter (ST). Existing baseline models considered for performance analysis assume perfect knowledge of the involved channels at the ST, however, such situations hardly exist in practical...
Engine control applications include computational activities that adapt their behavior as a function of the engine speed, referred to as adaptive variable-rate (AVR) tasks. Although a substantial amount of work has been done to analyze the timing behavior of real-time applications with AVR tasks, most of the authors assumed the knowledge of the instantaneous engine speed at any instant. In practice,...
Simulation and analytical tools are useful modeling methods to solve complex optimization problems. In this paper, we propose a simulation optimization framework called "Multi-fidelity Optimization with Ordinal Transformation and Optimal Sampling" (MO2TOS) when multi-fidelity models are available, and prove its efficiency by analyzing its convergence mechanism. The MO2TOS is a two-stage...
Software development mostly adopts two kinds of methodologies; Traditional and Agile. In both methodologies, software changes are inevitable due to the dynamic nature of the software development project itself. One of the factors that influences the effectiveness of the change acceptance decision is the accuracy of the change effort estimation. There are two current models that have been widely used...
Software effort estimation consists of those procedures and activities which help to predict most accurate development effort as well as cost of a software product. After analyzing various proposed concept and theories regarding this we tried to give a new concept which works over partition of a data set. The partition procedure depends over the correlation of input features as well as output features...
The solution of a fundamental problem at quality metering and comparison of objects with an arbitrary origin is offered. It is based on the use of system analysis principles, statistical and expert-analytical methods and methods of mathematical modeling. A model developed allows describing an object through quality metering under conditions when its investigation or estimation is carried out by one...
