In Iran and some other countries, elastomer bearings in seat-type bridges are used with no sole/masonry plates and there is no positive connection between superstructure and substructure. Different codes have diverse provisions regarding the coefficient of friction (μ) between elastomer bearing and superstructure/substructure and also the design strength of shear keys (Vsk). Developing a finite...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
Background and objective: The land subsidence is commonly associated with many risks. This phenomenon can cause substructure and natural damages, and ultimately leads to an increased risk in society and the economy. The most studies are focused on modeling and its techniques, except for two case studies in Tehran: the risk of subsidence phenomenon and the elements exposed to this risk which has...
Polydimethylsiloxane (PDMS) has been synthesized by ring-opening polymerization of octamethylcyclotetrasiloxane (D4) in microemulsion with acidic catalyst. The structure and properties of microemulsion were characterized by Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FT-IR), Photo Correlation Spectroscopy (PCS). The effect of the variation in pH value, amoun...
The continuous increase in the complexity of current designs generates logic circuits that are less immune to soft errors. As the soft error rate increases, Concurrent Error Detection (CED) techniques are becoming ever more essential. A plethora of research efforts have been expended in developing CED techniques that provide high levels of reliability [1, 2, 3]. Yet, the high overhead associate...
The satellite observations such as the Cluster mission with four-point measurements show some local fluctuations in the density gradient in the vicinity of the plasmapause. These structures are found over a broad range of spatial scales, with a size from 20 to 5000 km. Also, the simultaneous observations of the kilometric continuum by IMAGE (Imager for Magnetopause-to-Aurora Global Exploration)...
In our lives, reality becomes a game, and in the same way, the game becomes reality, the game is an exercise, simulation of real life on a smaller scale, then it extends itself into reality. This article aims to make a connection between decision making in game which comprises all the issues that intervene in the process and further making a connection with real life. The method for identificat...
small area estimation is a technique used to estimate parameters of subpopulations with small sample sizes. small area estimation is needed in obtaining information on a small area, such as sub-district or village. generally, in some cases, small area estimation uses parametric modeling. but in fact, a lot of models have no linear relationship between the small area average and the covariat...
The Gauß–Manin connection is an extra structure on the de Rham cohomology of any algebraic variety, ∇ : H dR/k −→ Ωk ⊗k H dR/k (its definition will appear below). If one believes the Hodge conjecture then for a given pure Hodge structure H there is at most one connection ∇ such that H is a Hodge substructure of a cohomology group of a smooth projective complex variety with ∇ induced by the Gauß...
