In a family of nine members, two had systemic lupus erythematosus and seven positive serological test results for syphilis. None of the affected subjects had a history or physical signs of syphilis, but two had positive results to the Treponema pallidum immobilisation test. The explanation for these findings is not known, but possibily they were all false-positive reactions.

This paper investigates the solutions to the functional equations that arise inter alia in Undiscounted Markov Renewal Programming. We show that the solution set is a connected, though possibily nonconvex set whose members are unique up to n* constants, characterize n* and show that some of these n* degrees of freedom are locally rather than globally independent. Our results generalize those ob...

Multi-objective De Novo linear programming (MODNLP) is problem for designing optimal system by reshaping the feasible set (Fiala [3] ). This paper deals with MODNLP having possibilistic objective functions coefficients. The problem is considered by inserting possibilistic data in the objective functions coefficients. The solution of the problem is defined and established under the using of effi...

in this paper,  a heuristic algorithm is proposed in order to solve a nonlinear lexicography goal programming (nlgp) by using an efficient initial point. some numerical experiments showed that the search quality by the proposed heuristic in a multiple objectives problem depends on the initial point features, so in the proposed approach the initial point is retrieved by data envelopment analysis...

In this paper, the efficient multi-step differential transform method (EMsDTM) is applied to get the accurate approximate solutions for strongly nonlinear duffing oscillator. The main improvement of EMsDTM which is to reduce the number of arithmetic operations, is thoroughly investigated and compared with the classic multi-step differential transform method (MsDTM). To illustrate the applicabil...

Nous pr esentons un algorithme parall ele d eterministe pour la r esolution d'un syst eme d' equations lin eaires Ax = b sur un corps de caract eristique nulle. Cet algorithme s'ex ecute en temps O(log 2 n) et utilise O(M(n)) processeurs arithm etiques si M(n) est le nombre de processeurs requis pour le produit de matrices en temps O(log n). Abstract. We present a deterministic parallel algorit...

We present eecient algorithms for solving Legendre equations over Q (equivalently, for nding rational points on rational conics) and parametriz-ing all solutions. Unlike existing algorithms, no integer factorization is required , provided that the prime factors of the discriminant are known.

here‎, ‎we aim to develop a new algorithm for solving a multiobjective linear programming problem‎. ‎the algorithm is to obtain a solution which approximately meets the decision maker's preferences‎. ‎it is proved that the proposed algorithm always converges to a weak efficient solution and at times converges to an efficient solution‎. ‎numerical examples and a simulation study are used to...
