Many liquid storage tanks around the world have affected by earthquakes. This structure can store dangerous chemical liquids. Hence dynamic behavior of ground supported rectangular storage tanks is very important due to their applications in industrial facilities. In current research, the seismic behavior of two water storage rectangular concrete tanks is examined. For this purpose, these tanks...

the functional response is an important characteristic of predator–prey interactions that determinate which predator species or stage classes of predator is the most effective for pest control. host plant morphological characteristics are the effective factors on predator’s functional response. the objective of this study was to determine whether differences in trichome density of wheat cultiva...

In this paper, we prove that a mean system utilization smaller than one is necessary condition for the feasibility of real-time systems. Such systems are defined as stable . Stable have two distinct states: transient state, followed by steady-state where same distribution response times repeate...

Endurance Time Acceleration Functions are specially predesigned intensifying excitation functions that their amplitude increases with time. On the other hand, wavelet transform is a mathematical tool that indicates time variations of frequency in a signal. In this paper, an approach is presented for generating endurance time acceleration functions (ETAFs) whose response spectrum is compatible w...

As a key issue in distributed monitoring, time series data are a series of values collected in terms of sequential time stamps. Requesting them is one of the most frequent requests in a distributed monitoring system. However, the large scale of these data users request may not only cause heavy loads to the clients, but also cost long transmission time. In order to solve the problem, we design a...

Thin films of SnO2 nanowires were successfully prepared by using chemical vapor deposition (CVD) process on quartz substrates. Afterwards, a thin  layer of palladium (Pd) as a catalyst was coated on top of nanowires. For the deposition of Pd, a simple and low cost technique of spray pyrolysis was employed, which caused an intensive enhancement on the sensing response of fabricated sensors...
