The paper introduces a method for adaptive deductive synthesis of state models, complex objects, with multilevel variable structures. makes it possible to predict the objects using data coming from them. are collected sensors installed on Multilevel knowledge graphs (KG) used describe observed objects. new develops previously proposed inductive and methods, allowing context be taken into accoun...

a large number of authors have studied to find out how to control scouring around a pier along direct stream. the objective of this research is then to study a scour pattern around such piers on curves rivers due to the fact that there may be a difference between a flow pattern on a direct line and the meander. thus, this study tries to check whether the use of cable and collar alone and in a c...

in this paper, a new approach to modify cable tension measuring mechanism is described; furthermore, the constructed boards which amplify load cell output are introduced. this approach has some advantages including of providing feedback for motors, evaluating the robot’s ultimate load carrying capacity, improving the motor control system and estimating the vibrating deflections of the end effec...

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

in this paper robust pid control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. in dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. to develop the idea of control for cable robots with elastic cables, a robust pid control for cable driven robots with ideal rigid cables is firstly de...

Submarine lifelines (pipelines and cables) often cross areas characterized by earthquake-related geohazards (tectonic faulting, landslides seabed liquefaction). Avoiding geologically hazardous increases the length (i.e., cost), whereas a potential crossing may detrimentally affect structural performance of infrastructure, requiring more sophisticated design approaches and/or costly probably imp...

This paper presents the main findings when approaching an optimization problem proposed to us by a telecommunication company in Austria. It concerns deploying a broadband telecommunications system that lays optical fiber cable from a central office to a number of end-customers, i.e., fiber to the home technology. End-customers represent buildings with apartments and/or offices. It is a capacita...

Distributed fiber optic sensing presents unique features that have no match in conventional sensing techniques. The ability to measure temperatures and strain at thousands of points along a single fiber is particularly interesting for the monitoring of elongated structures such as pipelines, flow lines, oil wells, and coiled tubing. Sensing systems based on Brillouin and Raman scattering are us...

One of the major challenges to providing full-rate digital subscriber line (xDSL) access to residential customers in rural or remote locations is the use of existing copper infrastructure. First, copper is not particularly good for moving high frequencies over extended distances. Second, much of the existing copper in the United States is of diminished quality. Third, digital loop carriers, bri...
