Soft Constraints at Interfaces
نویسندگان
چکیده
Assuming that grammar is best modeled as a set of modules each representing a constraint system, like other human cognitive faculties, these constraint systems are bound to disagree and soft constraints are needed for conflict resolution among modules. This paper outlines an approach to incorporate soft constraints among grammar modules. The paper first goes over the issue of modularity and conflicting requirements. It then summarizes a generalized theory of soft constraint satisfaction (SCSP). It then outlines a linguistic constraint system based on SCSP theory. Finally, it shows how the type antecedent constraints of HPSG can be extended in an SCSP-based framework to allow for constraint violations and gradient constraints.

Analysis of Laminated Soft Core Sandwich Plate Having Interfacial Imperfections by an Efficient C0 FE Model
An efficient C0 continuous two dimensional (2D) finite element (FE) model is developed based on a refined higher order shear deformation theory (RHSDT) for the static analysis of soft core sandwich plate having imperfections at the layer interfaces. In this (RHSDT) theory, the in-plane displacement field for the face sheets and the core is obtained by superposing a globally varying cubic displa...
متن کاملOn the Displacement-Stress Continuous Finite Elements
For the analysis of composite media, three different compatible and mixed finite element formulations are presented which apriori enforce the continuity of stresses as well as displacements at the element interfaces. The formulations are applied for the analysis of hi-material interfaces in two problems often encountered in the field of orthopaedic biomechanics, that is the fixation analysis in...
متن کاملConstraints Analysis of Poultry Production at Dzongu Area of North Sikkim in India
A study was conducted at five villages of Dzongu, North Sikkim in India to identify various constraints faced by the farmers during poultry production. Selection of respondents of poultry farmers was done on the basis of Simple Random Techniques. The data were collected from each respondent through structured questionnaire as well as self observations. The study indicated that the input (82.25%...

In this paper, natural frequencies of the sandwich plates with soft flexible core and composite face sheets are obtained. Three-Dimensional (3D) finite element method (FEM) is used for constructing and analyzing of the sandwich plates to obtain their natural frequencies. Continuity conditions for transverse shear stresses at the interfaces as well as transverse flexibility and transverse normal...

University course timetabling problem is a complicated problem and finding a computer-aided solution for it was a subject to work for many years. To solve this problem, we must assign courses to timeslots with respect to hard and soft constraints. Hard constraints are those which must be necessarily met (some of them could be neglected with high costs). Our aim is to meet as many soft constrain...
