Because some genes have been cloned that have a known biochemical or physiological function, genetic variation can be measured in a population at loci that may directly influence a phenotype of interest. With this measured genotype approach, specific alleles or haplotypes in the probed DNA region can be assigned phenotypic effects. In this paper we address several problems encountered in implem...
Phylogenetic analyses of genetic data arising from 144 gene loci are used to describe the interrelationships among 24 widely used inbred strains of mice. An unordered-parsimony analysis gives a cladogram that is virtually identical to the known genealogy of the mouse strains. A loss-parsimony analysis is used to evaluate the hypothesis that the observed patterns of genetic divergence among thes...
In this paper, we establish a convergence result for equilibria in systems of social interactions with many locally and globally interacting players. Assuming spacial homogeneity and that interactions between different agents are not too strong, we show that equilibria of systems with finitely many players converge to the unique equilibrium of a benchmark system with infinitely many agents. We ...
This paper addresses the problem of fault detection and isolation of wind turbines using a mixed Bayesian/Setmembership approach. Modeling errors are assumed to be unknown but bounded, following the set-membership approach. On the other hand, measurement noise is also assumed to be bounded, but following a statistical distribution inside the bounds. To avoid false alarms, the fault detection pr...
Entropy generation in adiabatic flow of highly concentrated non-Newtonian emulsions in smooth tubes of five different diameters (7.15–26.54 mm) was investigated experimentally. The emulsions were of oil-in-water type with dispersed-phase concentration (φ ) ranging from 59.61–72.21% vol. The emulsions exhibited shear-thinning behavior in that the viscosity decreased with the increase in shear ra...
This paper addresses the problem of estimating the 3D model of an object from a sequence of images where the object is visible from different point of views. In particular, the paper considers the case of turntable image sequences, i.e. images captured under circular motion. A new method is hence proposed for this problem, which consists of determining the image point correspondences of each 3D...
Theoretical considerations often suggest that ecological parameters of insects evolve rapidly, so that close taxa differentiate or distant ones converge. Phylogenetic analysis provides evidence both for and against such hypotheses. Ecological data may be incorporated into phylogeny reconstruction or evaluated against existing cladograms. Explicit statements regarding definition of alternative c...
A method is presented to optimize chromosomal data on a cladogram. This procedure simultaneously considers variation at the nucleotide and locus levels including nucleotide substitution, insertion and deletion, locus insertions and deletion, and gene rearrangement. Locus labeling is not a requirement of the procedure and such annotation will result from the dynamic homology analysis of the chro...
The paper deals with a step-wise analytic hierarchy process (AHP) applied by a group of decision makers wherein nobody has a dominant position and it is unlikely to come to terms with respect to either the weights of different objectives or expected utilities of different alternatives. One of the AHP outcomes, that is the consistency index is computed for each decision maker, for all other deci...
Project delivery system selection is an essential part of project management. In the process of choosing appropriate transaction model, many factors should be under consideration, such as the capability and experience of proprietors, project implementation risk, and so on. How to make their comprehensive evaluations and select the optimal delivery system? This paper proposes a decision-making a...
