in practice, foundations are settled on the soft layers of soil, so the ground must be designed as well as the structure. wave propagation and hysteresis damping of soil layers may alter the seismic response of flexible-base design in comparison to controversial fixed-base. lots of uncertainties about this issue, necessitate most of seismic design standards including iranian standard no. 2800 t...

Since their emergence in 1970's, wireless networks have become increasingly popular in the computing industry. These networks provide mobile users with ubiquitous computing capability and information access regardless of the location. There are currently two variations of mobile wireless networksinfrastructured and infrastructure less networks. The infra-structured networks, also known as Cellu...

Wireless Mesh Network (WMN) is an ad-hoc network with a fixed network infrastructure (see an example in figure 1). The physical structure of a WMN includes base stations, a backbone and mobile stations. The base stations (also known as mesh routers or mesh points) are static wireless nodes, forming the network infrastructure and providing wireless network access to the mobile stations. The back...

Let F (x1, . . . , xm) = u1x1 + · · · + umxm be a linear form with relatively prime integer coefficients u1, . . . , um. For any set A of integers, let F (A) = {F (a1, . . . , am) : ai ∈ A for i = 1, . . . , m}. The representation function associated with the form F is RA,F (n) = card ({(a1, . . . , am) ∈ A m : F (a1, . . . , am) = n}) . The set A is an asymptotic basis with respect to F if RA,...

Compressed sensing (CS) has been verified that it offers a significant performance improvement for large quantum systems comparing with the conventional quantum tomography approaches, because it reduces the number of measurements from O(d2) to O(rd log(d)) in particular for quantum states that are fairly pure. Yet few algorithms have been proposed for quantum state tomography using CS specifica...

This study develops a fuzzy sliding mode controller (FSMC) based on a variable boundary layer. A fuzzy inference mechanism is used to on-line tune the thickness of the boundary layers of the controller. Minimum rule base has been used for the fuzzy inference system which results in low calculation effort. The aim of this paper is to design a controller which will eliminate the chattering of FSM...

We give exact and approximation algorithms for computing the Gromov hyperbolicity of an n-point discrete metric space. We observe that computing the Gromov hyperbolicity from a fixed base-point reduces to a (max,min) matrix product. Hence, using the (max,min) matrix product algorithm by Duan and Pettie, the fixed base-point hyperbolicity can be determined in O(n) time. It follows that the Gromo...

In this study, the seismic behavior of isolated- and fixed-base regular irregular reinforced concrete structures was investigated. For purpose, a three-dimensional, eight-story reference building model without any irregularity designed in accordance with Turkish Building Earthquake Code (TBEC-2018). Later, models irregularities were created using model. isolators fixed supports, fiber hinges us...

The influence of soil-structure interaction in the analysis and design of a 6-storey and basement reinforced concrete frame building is investigated. Models simulating two different conditions: namely soil-structure interaction, and fixed-base behavior are considered. The influence of the soil structure interaction in the dynamic behavior of the structure is reflected in an increase in the vibr...
