The following study deals with the updating the finite element model of structures using the operational modal analysis. The updating process uses an evolutionary optimization algorithm, namely bees algorithm which applies instinctive behavior of honeybees for finding food sources. To determine the uncertain updated parameters such as geometry and material properties of the structure, local and...

This paper is concerned with the design and analysis of a fully adaptive eigenvalue solver for linear symmetric operators. After transforming the original problem into an equivalent one formulated on `2, the space of square summable sequences, the problem becomes sufficiently well conditioned so that a gradient type iteration can be shown to reduce the error by some fixed factor per step. It th...

The web resource Regulatory Sequence Analysis Tools (RSAT) (http://rsat.ulb.ac.be/rsat) offers a collection of software tools dedicated to the prediction of regulatory sites in non-coding DNA sequences. These tools include sequence retrieval, pattern discovery, pattern matching, genome-scale pattern matching, feature-map drawing, random sequence generation and other utilities. Alternative forma...

application of radioactive isotopes is the treatment of choice around the globe for many cancer sites. in this technique, the accuracy of the radiation delivery is highly dependent on the accuracy of radiation dosimetry around individual brachytherapy sources. moreover, in order to have compatible clinical results, an identical method of source dosimetry must be employed across the world. this ...

Force field-based calculations of all-silica zeolites show the role fluoride as a structure-directing agent (SDA). Calculations fully packed organic and SDAs were possible with an updated version zeoTsda software, based on Monte Carlo+Lattice Energy Minimization. Comparison between fluoride-containing fluoride-free using same SDA allowed us to predict which zeolite phase is obtained in hydroxid...

Jujube (Ziziphus jujuba Mill.) fruit is an important medicinal plant in Iran. The harvesting time is a crucial for jujube fruit quality. Several characteristics of jujube fruit when harvested at four development stages; white mature (light green), crisp mature (white-red), fully mature (red) and fully ripe (dehydrated brown) were evaluated. Fruit weight, diameter, volume, pulp to stone ratio, f...

An updated checklist of the scorpion fauna of Iran, as well as a brief history of taxonomic research on scorpions of Iran is presented. The checklist is based on records of scorpion species whose presence has been confirmed in Iran through field expeditions, examination of scorpion collections, literature review, and personal communications from researchers. The scorpion fauna consists of 51 sp...

The ever-growing use of various vehicles for transportation, on the one hand, and the statistics ofsoaring road accidents resulting from human error, on the other hand, reminds us of the necessity toconduct more extensive research on the design, manufacturing and control of driver-less intelligentvehicles. For the automatic control of an autonomous vehicle, we need its dynamic...
