decision making and problem solving are especially important skills for business and life. as an innovation leading corporate, sony has gradually lost their superiority in innovation and core competences under more and more intensive competition environment. this report is made to investigate sony current procedure on its solving problems and making decision, analyze approaches and tools used b...

the aim of this paper is to introduce a new approach for obtaining the numerical solution of singulary perturbed boundary value problems based on an optimal control technique. in the proposed method, first the mentioned equations are converted to an optimal control problem. then, control and state variables are approximated by chebychev series. therefore, the optimal control problem is reduced ...

a bstract   background: midwifery profession is required to bring solutions to problems and a midwife is expected to be an assertive person and to develop midwifery care. this study was planned to examine the relationship between assertiveness and problem‑solving skills of midwives.   materials and methods: this cross‑sectional study was conducted with 201 midwives between july 2008 and februar...

Chomsky cannot help wondering at the fact that we, despite so vast evidence, have little knowledge about the obvious evidence. A good example, I think, is the child’s way of first language acquisition. A great many researchers have studied various aspects of child language acquisition at different stages of the child’ life and have brought to light many details of language development. However,...

objective: interventions for people suffering from borderline personality disorder (bpd), such as dialectical behavior therapy, often include a problem-solving component. however, there is an absence of published studies examining the problem-solving abilities of this client group in iran. the study compared inpatients and outpatients with bpd and a control group on problem-solving capabilities...

in this paper, we investigate the goursat problem in the class c21(d)cn0 (d  p) c00 (d q)for a third order pseudoparabolic equation. some results are given concerning the existence and uniquenessfor the solution of the suggested problem.

n this paper, we apply picard’s iteration method followed by adomian decomposition method to solve a nonlinear singular cauchy problem of euler- poisson- darboux equation. the solution of the problem is much simplified and shorter to arriving at the solution as compared to the technique applied by carroll and showalter (1976)in the solution of singular cauchy problem.

this paper is devoted to the proof of the unique solvability ofthe inverse problems for second-order differential operators withregular singularities. it is shown that the potential functioncan be determined from spectral data, also we prove a uniquenesstheorem in the inverse problem.
