  • Comparison between seismic retrofitting solutions for existing reinforced concrete buildings: a case study

    In assessing the safety of existing buildings, the specific actions dedicated to the knowledge of the structure delineate the parameters of the linear or non–linear analysis aimed at identifying the most appropriate structural intervention. In this context, the present paper collects the seismic analysis of a school building in reinforced concrete, illustrating the different stages concerning the ...

  • An environmentally–friendly integrated seismic imaging for coal exploration in the Miocene Soma Basin, Western Turkey

    Seismic reflection data from target depths of several hundred metres have been acquired and processed as an aid for lignite exploration in the Miocene Soma Basin, western Turkey. An environmentally–friendly approach was followed by acquiring the data with mini–vibroseisseismic source along crooked lines, using available mountain/forest and village roads; quality control tests were conducted to ...

  • The use of shallow high resolution seismic reflection data to determine drilling locations at the Apache powder superfund site.

    INTRODUCTION Groundwater contamination at the Apache Powder Superfund Site in Cochise County, Arizona includes dissolved nitrate-N and perchlorate. Past studies have determined that these contaminants migrate laterally from a perched zone underlying Apache Nitrogen Products, Inc. operating areas into the shallow aquifer of the San Pedro River alluvium (shallow aquifer). The base of both the ...

  • AMETEK PI wins stack gas/emissions analyzer category bronze medal award in control magazine reader choice awards

    Every single interaction between customer and supplier is an oppor-tunity for providing good solutions. After awhile, these positive mo-ments really begin to add up. Despite the huge effort and extreme consistency required, the best vendors almost re¬ exively deliver useful products and services, and con-tinually develop and release new improvements and innovations. Con-sequently, over ...

  • GPR: a new tool for structural health monitoring of infrastructure

    Abstract Recent developments in acquisition methodology, data acquisition systems, post-processing software, and the availability of user friendly high-frequency antennas have enabled the GPR user to generate accurate three dimensional images of the interior of concrete structures. Four case studies are discussed with emphasis on output that is readily understood by the ...

  • Brüel & Kjær accelerometers - 65 years of excellence

    The Thirties Already before the two young engineers Per V. Brüel and Viggo Kjær graduated as Masters of Electrical Engineering in 1939, they had decided to start a company together. However, they felt it was necessary to learn more and get some practical experience before actually going ahead, so P.V. Brüel became assistant to professor P.O. Pedersen in the newly created ...
