The satellite industry is clearly committed to revisit and revamp the role of satellite communications within the 5G ecosystem. Central technologies being adopted in 5G networks such as Software Defined Networking (SDN) and Network Function Virtualization (NFV) are also anticipated to become key technological enablers for improved and more flexible hybridization of both satellite and terrestria...

The purpose of this paper is to attitude estimation of Nano-satellite which requires navigation sensors data to less cost function and effection movement of Nano-satellite focus of the research is to using data of navigation sensors and methods to achieve the requirement of the attitude estimation. in this paper the following attitude estimation of the according to direction of sun of the Nano-...

The main purpose of the present study is to examine the role of TV satellite programs on family cohesion in Yazd city. The study was conducted as a survey. The sample size of divorce of people were 211 and for married ones were 323. Those divorced respondents were selected using stratified sampling and married respondents were selected using random sampling. The instrument used here was a quest...

Introduction: Satellite cells are known as the main regenerative cell type in skeletal muscles. Our study established a modified digestion and preplating method for the isolation of slow or weak adherent cells for the enrichment of satellite cells. Low-survival rate of these primary stem cells prompted us to address whether cell culture medium substitution might change cell viability status. M...

ecotones are zones of gradual changes from an ecological system to another.ecotones monitoring could be important to find out the reason for changes and limits. inthis research satellite data were used to analyze the ecotone boundary in fars steppicrangelands using irs liss iii and pan data of year 2006. the real vegetation map andecotones prepared through geo-eye images from google earth softw...

in this paper, a finite-time control scheme is presented for stabilization ofthe satellite chaotic attitude around its equilibrium point whenits attitude is confused by a disturbed torque. controllers and settling timeof stabilizaton are obtained, based on the lyapunov stability theoremand finite-time control scheme. this method is satisfied for any initial condition.numerical simulations are ...

U sers of communications satellites often ignore the actual hardware in space the makes their applications possible. To help fill this gap, we review some recent trends and developments of the kinds of satellites that operators are launching. This is not intended to encompass all of the systems and services that make up the industry, but rather selects some of the more salient elements that can...
