Hilbert frames theory have been extended to frames in Hilbert $C^*$-modules. The paper introduces equivalent $*$-frames and presents ordinary duals of a constructed $*$-frame by an adjointable and invertible operator. Also, some necessary and sufficient conditions are studied such that $*$-frames and ordinary duals or operator duals of another $*$-frames are equivalent under these conditions. W...

in this study, for evaluating ductility of ordinary concentrically braced frames (ocbfs) and special concentrically braced frames (scbfs) which are x- braced in two adjacent middle spans, 16 steel ordinary concentrically braced frames and 16 special concentrically braced frames are studied. the results confirm that, although most of ordinary concentrically braced frames, which are x-braced, can...

BACKGROUND The 2012 visit to Canada of Olivier De Schutter, the United Nations Special Rapporteur on the Right to Food, led to a public rebuff by Canadian governmental officials. This paper adapts the frame-critical policy analysis of Schön and Rein (1994), to explore the rhetorical basis for this conflict. This examination is offered as an illustrative example of how food insecurity is framed ...

in this paper we proved that every g-riesz basis for hilbert space $h$ with respect to $k$ by adding a condition is a riesz basis for hilbert $b(k)$-module $b(h,k)$. this is an extension of [a. askarizadeh,m. a. dehghan, {em g-frames as special frames}, turk. j. math., 35, (2011) 1-11]. also, we derived similar results for g-orthonormal and orthogonal bases. some relationships between dual fram...

development of new methods in seismic analysis and increasing application of performance based seismic design necessitate the study of the seismic performance of structures designed based on iranian regulations. in this study the seismic performance of steel moment-resisting frames designed based on the tenth code of the iranian national building regulations is investigated. frames are differen...

Textiles for apparels are constructed by innovative methods in construction by weaving or knitting to get the end product requirements of better strength, extension, elasticity, hand and resistance to abrasion. Woven and knitted fabrics are widely used and known for their respective properties of firm shape and elastic properties. Their drawback of rigidity and deformation of shape are overcome...

The evolution of damage in a woven composite results from the interaction and competition among several elementary mechanisms which are greatly influenced by the microstructure. Thus, in order to develop a model as close as possible to the physics, it is necessary to observe, understand and describe each mechanism on the most appropriate scale. In this work, the construction of a woven composit...

Woven coronary artery is extremely rare. It is characterised by thin channels arising from the coronary artery and reanastamosis at the distal portion. A 62-year-oldman was diagnosed of coronary artery disease. Coronary angiography showed 3-vessel coronary artery disease. The distal right coronary artery derived 3 twisting thin channels, and the inferior thin channel sprouted second-class thin ...

We present an extension of the theory of graph rotation systems, which has been a widely used model for graph imbeddings on topological surfaces. The extended model is quite beyond what is needed to specify graph imbeddings on surfaces, and it can be used to represent and generate link structures immersed on surfaces. Since link structures immersed on surfaces can be viewed as woven images in 3...
