in this paper, efforts are made to compare the safety of steel moment resistant frames designed according to different editions of the iranian code of practice for seismic resistant design of buildings. also, failure risk of a low and medium height frame which designed for high and low seismicity regions according to three editions of the code are evaluated. first, the testing cases were design...

With the realization of larger and more complex space installations, an increase in surface area exposed to atomic oxygen (AO) ultraviolet (UV) effects is expected, making structural integrity structures essential for future development. In a low Earth orbit (LEO), AO UV degradation can have devastating consequences polymer composite satellites installations. Composite materials such as carbon ...

This paper addresses a major challenge in the residential solar industry: automated design of cost-effective, efficient rooftop photovoltaic (PV) installations. Optimal designs choose system components, locations, and wiring to minimize cost while meeting desired energy output and complying with all physical and legal constraints. We present a novel lower bound for the energy produced by a PV i...

Media architecture has emerged as a relevant field of study within HCI since its inception at the turn of the century. While media architecture has the potential to radically affect the social space into which it is introduced, much research in the field was initially carried out through experimental installations in public spaces, often with higher emphasis on examining the properties of this ...

Software installation provides an attractive entry vector for malware: since installations are performed with administrator privileges, malware can easily get the enhanced level of access needed to install backdoors, spyware, rootkits, or “bot” software, and to hide these installations from users. Previous research has been focused mainly on securing the execution phase of untrusted software, w...

Denote by Fin(v) the set of all integer pairs (t, s) for which there exist three Latin squares of order v on the same set having fine structure (t, s). The set Fin(v) with v ≥ 2 and v = 5, 6, 7, 8 is determined in [2]. In the present article the set Fin(8) is finally determined. Some results on Fin(v) with 5 ≤ v ≤ 7 are also updated.

The paper presents mainly the possibility of introducing on process distributed and decentralized modular structures which use programmable logical automates, thereby offering all the facilities for real time control and additionally the possibility of interactive interfacing with a PC by developing an open architecture system. To this end, a modular structure in open architecture system is dev...

doing a piece of research on acquisition of second language phonetics theoretically will justify the exact stages of language trans- fer and further predicts the existence of systematicity and difficulty order (eckman, 2008). the present research is an attempt to provide new evidence for the efficacy of second language acquisition to devel- opmental stages of acquisition of phonological structu...
