this paper provides an analysis of persian verbs within the framework of optimality theory. to be more specific, it mainly cocentrates on past and present stems of persian verbs. since analyzing this subject within the derivational framework would result phonological rules which are not natural, it is analysed by optimality theory which is one of the constraint-based approach. based on this, we...

In order to solve the A-body Schrödinger equation both accurately and efficiently for open-shell nuclei, a novel many-body method coined as Bogoliubov perturbation theory (BMBPT) was recently formalized applied at low orders. Based on breaking of U(1) symmetry associated with particle-number conservation, this must operate under constraint that average number particles is self-consistently adju...

During the last 25 years the complexity and functionality of software systems has increased dramatically. Software systems have to be updated and restructured continuously [22]. In some cases it might be a solution to implement a completely new system from scratch but in the majority of cases the costs and the risks are too high and a solution for successful software evolution is needed [76]. N...

The System Resource Constraint Theory intends to research growth of economy under different classes of system resource constraint. By analogy between ecology system and economic system, from the angle of total nature resource, total supply ability and total market volume, the theory focuses on the constraint condition and development characteristic of economy as well as the various game charact...

The goal of theory of constraints (TOC) is to maximize output, which is achieved byidentifying and managing the critically constrained resources. To manage the constraints, Goldrattproposed five focusing steps (5FS). If we increase constrained output, the output of system will beincreased. In this paper, we focus on step four of the 5FS and use the remained capacity of nonconstraintto elevate t...

the present research aims to study the effects of syllabic structure in standard tajiki persian on the pronunciation of standard iranian persian words and the joint loanwords in these languages. this descriptive study used optimality theory, as a recent branch of generative grammar, to analyse the errors. to that end, ten tajiki-speaking persian learners, studying at imam khomeini international...
