The Jean River near Wabush, Labrador is crossed by two railways and an access road by twin 6m diameter culverts . They are heavily strutted inside their barrels to counteract some significant shape deformation, and are deemed not suitable to sustain the increased volume of rail traffic serving the development of the Bloom Lake mines. The owner requested the design and construction of a replacement scheme for an additional design life of 20 years with a time sensitive schedule for completion of the work during the 2013 construction season. This VE concept for the design of live load relief spans …

Active Tuned Mass Damper Control Of Wind Turbine Nacelle/Tower Vibrations With Damaged Foundations, Breiffni Fitzgerald
Active Tuned Mass Damper Control Of Wind Turbine Nacelle/Tower Vibrations With Damaged Foundations, Breiffni Fitzgerald
Breiffni Fitzgerald
The aim of this paper is to develop an active structural control scheme to control wind turbine nacelle/tower out-of-plane vibration. An active tuned mass damper (ATMD) is designed an placed inside the turbine nacelle. An EulerLagrangian wind turbine model based on energy formulation is developed for this purpose, which considers the structural dynamics of the system and the interaction between in-plane and out-of-plane vibrations. Also, the interaction between the blades and the tower including the ATMD is considered. The wind turbine is subjected to gravity and turbulent aerodynamic loadings. A three-dimensional (3D) model of a wind turbine foundation is designed …

Backend Framework And Software Approach To Compute Earthquake Parameters From Signals Recorded By Seismic Instrumentation System, Raman Attri
Raman K. Attri
Computation of seismic parameters and its interpretation from the recorded earthquake signal is empowered by digital data acquisition systems. This enables seismologist to automatically compute all the relevant parameters. Futuristic applications require extensive software development to implement seismic prediction and forecasting models. While developing such models, software developer prefer to write their own in-house analysis & modeling software with complete control over the required computations and models. This paper presents simplified mathematical framework of the seismic events and back-end computational software logic & algorithm to provide a simple framework to software engineers develop customized seismic analysis & computation software.
Non-Contact Detection Techniques And Technologies For Detection Of Objects In Air, Under-Ground And Under-Water, Raman Attri
Non-Contact Detection Techniques And Technologies For Detection Of Objects In Air, Under-Ground And Under-Water, Raman Attri
Raman K. Attri
In this white paper, we will present review and compilation of various object detection techniques currently available in different scenarios and situations. Automatic Object detection in the air, beneath other materials, under water and under the earth surface as well as over the surface is one of the advanced sciences employing many principles of multiple engineering domains together. “See-through” methods – seeing beyond the visible objects, has been inherent desire of human being since the practice of science. Not only this, a craving to detect the objects without directly “seeing upon” them with naked eyes calls upon some automatic procedures …

A Simplified Overview: How The Earthquake Parameters Are Computed From Recorded Seismic Signals?, Raman Attri
A Simplified Overview: How The Earthquake Parameters Are Computed From Recorded Seismic Signals?, Raman Attri
Raman K. Attri
The earthquake phenomenon is one of the unpredictable and complex geo-logical phenomenon happening under the earth surface. The recording and its interpretation of recorded earthquake signal have always been a prime concern of the seismologists. This paper discusses in a very simplified manner how these complex parameters are computed.

In late June 1998, a major storm event occurred in the Adirondack Mountains in the vicinity of Keeseville, New York about 150 miles north of Albany. This storm resulted in unprecedented damage to the Canadian Pacific Railway (CPR) Canadian Mainline along the shores of Lake Champlain. The storm caused 14 major embankment failures and washouts, numerous minor failures, severe bridge foundation scour and a major mainline derailment.

Since a long time leading organisations have been advocating the need of implementation of IT in a centralised manner on the distributed geological data monitoring centres. In the era of IT, it is highly important to access, share and analyse related data on a common platform for fast retrieval of information in centralised as well as in distributed mode. In this article a concept to integrate Geo-Scientific Instrumentation systems to Information Technology has been highlighted. The vision to create a Geo-Scientific Information System (GSIS) would be an approach where a centralised web-enabled database of the data acquired & transmitted by …
