in this paper the control algorithm for controlled civil structures subjected to earthquake excitation is thoroughly investigated. the objective of this work is the control of structures by means of the pole placement algorithm, in order to improve their response against earthquake actions. successful application of the algorithm requires judicious placement of the closed-loop eigenvalues from ...

The designated fiber stress values published in the American National Standards Institute Standard for Poles, ANSI O5.1, no longer reflect the state of the knowledge. These values are based on a combination of test data from small clear wood samples and small poles (<55 ft (<17 m)) and field experience up to the time of adoption of the standard in 1965. A number of changes over the past 35 year...

This paper presents a new fast-acting backup protection strategy for future hybrid ac-dc distribution networks. By examining the impedance measured by distance relay measuring from “ac-side” of network, unique characteristic is established faults occurring on “dc-side” an embedded medium-voltage dc (MVDC) link, interconnecting two 33 kV network sections. Based identified characteristic, appropr...

s | 91 Methods: Forty-five right-handed patients with PD who met the diagnostic criteria in Structured Clinical Interview for DSM-V and twenty-two healthy control were examined by means of MRI at 3 Tesla. We used the FreeSurfer software package to create a three-dimensional model of the cortical surface for estimating the cortical thickness. In order to test the effect of the gene polymorphism ...

To test the "traction fiber" model for metaphase positioning of bivalents during meiosis, kinetochore fibers of maloriented bivalents, induced during recovery from cold arrest, were analyzed with a liquid crystal polarizing microscope. The measured birefringence retardation of kinetochore fibers is proportional to the number of microtubules in a fiber. Five of the 11 maloriented bivalents analy...

Posterior polar plasm of the Drosophila egg has been shown to function autonomously in germ cell determination after transplantation to either the anterior or mid-ventral region of the early embryo. By means of similar transplantations, we have tested the ability of polar plasm of Drosophila immigrans to induce the formation of pole cells in a Drosophila melanogaster embryo. After the transplan...

CONTEXT AND OBJECTIVE Patellar tendinopathy is a common condition in sports. It may occur at any location of the patellar tendon, but the most commonly affected area is the inferior pole of the patella. Among various diagnostic tests, the one most used is palpation of the inferior pole of the patella. The aim of this study was to investigate the prevalence of pain complaints among individuals w...
