This paper proposes a Time Delay nonlinear dynamic model of HIV-1 (Human Immunodeficiency Virus type 1), introducing the drug consumption efficiencies as the controlling input for the model. The paper also represents the fuzzy T-S representation and the corresponding Fuzzy T-S controller. The controller parameters are tuned using LMIs (Linear Matrix Inequalities). The main focus is on the stabi...

The paper substantiates the possibility of applying mathematical theory continuous problems optimal partitioning sets n-dimensional Euclidean space, which belong to non-classical infinite-dimensional programming, solution artificial intelligence and pattern recognition. recognition both in conditions certainty uncertainty are formulated. A particular attention is paid application methods for co...

The Automated Software Engineering Group (ASE) at NASA Ames Research Center is a research group investigating state-of-the-art veri cation and program generation technologies. As part of this e ort, the ASE recognize the importance of UML within NASA's software projects (e.g., the Mission Data System at the Jet Propulsion Lab, Pasadena) and are currently developing ways in which ASE technologie...

Abstract Regression test selection (RTS) approaches reduce the cost of regression testing evolving software systems. Existing RTS based on UML models use behavioral diagrams or a combination structural and diagrams. However, in practice, are incomplete not used. In previous work, we proposed fuzzy logic approach called FLiRTS that uses sequence activity this introduce 2, which drops need for re...

Adequate coverage is one of the main problems for distributed wireless sensor networks and The effectiveness of that highly depends on the sensor deployment scheme. Given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. In this paper, we apply fuzzy logic system to...

This contribution presents a new approach, based on Fuzzy Prototypical Knowledge Discovery, to predict the maintainability of class diagrams done using the Unified Modelling Language (UML), which has great importance on the final quality of object-oriented information systems (OOIS). The prediction model is built from metrics values obtained at the early phases of OOIS life-cycle. We will start...

-The paper deals with an analytical tool proposed as a pre-processing stage for the fuzzy control of a servodrive. Several relations are aimed to optimize both the correlation of the plant / controller parameters and the real-time implementation. This study is focused on positioning systems, where the fast response and the accuracy are very important. The results as simulation diagrams, on-line...

Defining a complete methodology for the developing of an application is a challenge for many software engineering specialists. Although many such methodologies have been developed, few of them take into consideration all the aspects that can come up while developing complex applications. Many times, although a general outline for the methodology is being defined, for some important features, li...

The subject of the study is design of multi-valued (analog) CMOS fuzzy controllers. A functional completeness of summing amplifier with saturation in a multivalued logic of an arbitrary value proven in previous works gives a theoretical background for analog implementation of fuzzy devices. Compared with the traditional approach based on explicit fuzzification / defuzzification procedures analo...
