Auxetic cellular solids in the forms of honeycombs and foams have great potential in a diverse range of applications, including as core material in curved sandwich panel composite components, radome applications, directional pass band filters, adaptive and deployable structures, filters and sieves, seat cushion material, energy absorption components, viscoelastic damping materials and fastening...

objective: the purpose of this study was to examine the impact of early family-centered psychological and educational interventions on adaptive behaviors in children with down syndrome (ds). method: utilizing an experimental pretest-posttest control group design, parents of 36 children with ds were selected in isfahan. vineland adaptive behavior scale was used to assess adaptive behavior. resul...

The goal of this paper is to describe a new approach to a content creation and delivery mechanism for a programming course. This approach is based on the concept of creating a large repository of learning objects, each of which consists of the core material, code examples, supplementary notes, and review questions. A learning object will be uniquely described by a XML document and presents an i...

Designing adaptive learning activities, i.e. activities which provide learner-dependant variant learning experiences, is an inherently demanding pedagogical task. Designing adaptive elearning activities should not add disproportionate technical difficulties to the task. IMS-Learning Design purports to provide a pedagogically neutral and technically smooth environment for the design of education...

the synthesis of nano- structured cobalt through a controlled chemical process followed by heat treating at various temperatures is studied. the product is characterized by icp, xrd, fesem , and tem, indicating that the as- synthesized particles have an amorphous structure with 1.76 for co/b ratio, an average size of 50 nm. the transformation of intermediate phases into single phase nano- cryst...

this paper presents fuzzy and conventional performance of model reference adaptive control(mrac) to control a dc drive. the aims of this work are achieving better match of motor speed with reference speed, decrease of noises under load changes and disturbances, and increase of system stability. the operation of nonadaptive control and the model reference of fuzzy and conventional adaptive contr...

Introduction:  Breast  cancer  is  a  leading  cause  of  death  among  females  throughout  the  world.  Currently,  radiologists are able to detect only 75% of breast cancer cases. Making use of computer-aided design (CAD)  can play an important role in helping radiologists perform more accurate diagnoses.   Material and Methods: Using our hybrid method, the background and the pectoral muscle...

Background: The exposure of cell lines to low-dose irradiation leads to changes at molecular level, which may induce adaptive response. We examined radio-adaptive doses effect on human colorectal adenocarcinoma cell line (HT29) and human fetal fibroblasts (MRC5) cell line followed by hyper and hypo fractionation regimes, with main purpose to decrease cell viability in HT29, and at the same time...
