Abstract To study the impact of various defects associated close to surface layer CdTe material, we use scanning laser Transient Current Technique. This gives us an overview different compositional inhomogeneities, such as dislocations, grain boundaries, and tellurium inclusions. Particularly, reconstructed high resolution spatial images provide a map electrically active defects. Each point con...

effective elastic properties for carbon nanotube reinforced composites are obtained through a variety of micromechanics techniques. an embedded carbon nanotube  in  a  polymer  matrix  and  its surrounding  interphase  is  replaced with an equivalent fiber for  predicting  the  mechanical  properties of  the  carbon  nanotube/polymer composite. the effects of an interphase layer between the nan...

the usage of ceramic composites in order to improve the workability and properties of clay already has past a long history behind. in spite of the fact that clay by its own is a flexible and appropriate material for sculpting and ceramic making, it also carries some problems, flaws and imperfections (such as cracking, heaviness and etc.) which make it somehow troublesome to work with. from the ...

Arising as a new class of energetic material, nanoporous energetic silicon holds great potential for applications such as fuzing and thrust generation, which require large power output. In this paper we address fabrication and material characterization as well as monolithic integration of a hotwire initiator and packaging; the first steps toward a fully integrated MEMS/IC/energetic material sys...

PURPOSE The objective of this study was to describe the process of elaboration and evaluation of multimedia material for caregivers about velopharynx, speech, and primary palatoplasty in babies with cleft lip and palate. METHODS The elaboration of the material involved an interdisciplinary relationship between the fields of Speech Language Pathology and Audiology, Dentistry and Arts. The defi...

This paper presents an Abaqus/Explicit simulation of the impact event when a golf club hits a golf ball. This is a challenging subject for finite element simulations because of it is characterized by high strain rate behavior. The simulation emphasizes accurate material characterization and realistic model construction. Specifically, an advanced nonlinear viscoelastic material model from Veryst...

In this paper, we present characterizations of pairs of graphs whose join graphs are 2-minimally nonouterplanar. In addition, we present a characterization of pairs of graphs whose join graphs are 2-minimally nonouterplanar in terms of forbidden subgraphs.

For the family of graphs with xed-size vertex cover k, we present all of the forbidden minors (obstructions), for k up to ve. We derive some results, including a practical nite-state recognition algorithm, needed to compute these obstructions.
