This article reports efforts to devise frameworks for quickly and easily characterizing 13 different supervisory control applications developed and tested by the international participants in a North Atlantic Treaty Organization working group on supervisory control of multiple uninhabited vehicles (UVs). Multiple prior frameworks for supervisory control are reviewed, and two novel ones (a more ...
The kinetics of thermal decomposition of AlIII -, CrIII -, FeIII ,CeIII and LaIII -alginate complexes have been studied using thermogravimetry (TG) and differential thermogravimetry (DTG) techniques in static air. However, the TG curves showed three distinct stages of weight loss, the DTG curves indicated the presence of a series of thermal peaks associated with the TG curves. The results revea...
This report describes the ethical and legal aspects of assisted reproduction technology (ART) that have been instituted in Asian countries. The data were collected by a questionnaire circulated to ART units in Asia. These are Taiwan, Singapore, Korea, Indonesia, Thailand, Japan, Iran, India, Jordan, Malaysia, China, Israel, Hong Kong, Pakistan, Lebanon, Saudi Arabia, and Persian Gulf countries....
In the presence of nuisance parameters, we derive an explicit higher order asymptotic formula to compare the expected lengths of conndence intervals given by likelihood ratio statistics arising from the usual proole likelihood and various adjustments thereof. Highest posterior density regions, with approximate frequentist validity, are also included in the study.
This paper deals with the design and parameter identification of hydrodynamic models based on the mass density conservation equation properly closed by suitable relations linking mass velocity to the local density profiles. The contents are proposed in three parts. First, various experimental data are phenomenologically interpreted and constrained into suitable analytic models. Then the above m...
In this paper, the unsteady oscillatory flows of a generalized Burgers’ fluid in a rotating frame are investigated. The constitutive equations of the generalized Burgers’ fluid are used in the mathematical formulation of the problem. The solutions are obtained by using the Laplace transform method. The graphical results are displayed and discussed for various parameters of interest. It is found...
The Zone System has been the established methodology for precisely gauging and managing contrast in photography since the 1940s. In the contemporary digital era, only a small number of mostly film photographers expose their images according to original Zone technique with its quantitative scale for engaging differences in illumination. Nevertheless the principles and parameters of Zone methodol...
Although it was proven by Vapnik that SVM is capable of finding optimal solutions, the full success can be achieved only if the adaptive process parameters (C and kernel functions parameters) are set to proper values. Manual parameters tuning is sometimes tricky. We propose a new way of automatic selection of the parameters. The criterion used to estimate C and kernel parameters aims in optimal...
Fault detection, fault isolation and fault diagnosis are addressed within a statistical framework. The corresponding inference problems are stated. Several statistical tools for solving these inference problems are described. Particular emphasis is put on dealing with nuisance parameters and deciding between multiple hypotheses. How to use these tools for solving FDI problems is discussed. An e...
Genotype-environment interaction was studied in seven genotypes of chickpea under four different cultural environments. Significant variation for genotype (G), environment (E) and G × E interactions were found for the characters days to maturity, plant height, pods/plant, seeds/plant, 100-seed weight and seed yield/plant. On the basis of stability parameters the genotypes Barichola-2, Barichola...
