We propose and analyze a generalized self-healing key distribution using vector space access structure in order to reach more flexible performance of the scheme. Our self-healing technique enables better performance gain over previous approaches in terms of storage, communication and computation complexity. We provide rigorous treatment of security of our scheme in an appropriate security frame...

The objective of this study was to develop a new optimal parallel algorithm for matrix multiplication which could run on a Fibonacci Hypercube structure. Most of the popular algorithms for parallel matrix multiplication can not run on Fibonacci Hypercube structure, therefore giving a method that can be run on all structures especially Fibonacci Hypercube structure is necessary for parallel matr...

In this paper a new low profile Substrate Integrated Waveguide (SIW) probe-fed H-plane horn antenna structure with improved gain is proposed. The proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...

introduction: hospital has a complex and special structure and the important question that hospital management facing with is how technology can change structure. in the near future, no factor like it is able to change the structure of organization. this research is a way to know the effect of it on triple dimensions of organization structure includes complexity, formalization, and centralizati...

introduction: in recent years spatial justice has gained special importance among planners and geographers. since the urban public services form the structure, shape and the nature of the physical, social and urban space, inequities in their distribution cause irreversible negative effects on the structure and the nature of city and social segregation of the people, and serious challenges in th...
