(DFI, 2009-10)Jet grouting is a ground improvement technique that has become widely adopted over the past three decades, yet relatively little data has been published about performance characteristics of mixes under adverse conditions, ...

(American Society of Civil Engineering (ASCE), 2009-11)Aerial Light Detection and Ranging (LiDAR) offers the potential to auto-generate detailed, three-dimensional (3D) models of the built environment in urban settings. Auto-generation is needed as manual generation is not ...

(International Association of Bridge and Structural Engineers, 2009-05)The use of aerial laser scanning to detect change in infrastructure and buildings after major disasters has become increasingly common in recent years to help prioritize interventions. More recent efforts are being invested ...
-
(International Society of Photogrammetry and Remote Sensing, 2009-02)In recent years, three-dimensional (3D) data has become increasingly available, in part as a result of significant technological progresses in Light Detection and Ranging (LiDAR). LiDAR provides longitude and latitude ...
-
(American Society of Civil Engineering (ASCE), 2009-03)The ultimate goal of the project reported herein was to determine whether or not a readily quantifiable threshold data density could be established to accurately predict subsurface lithology. A study area in Dublin Ireland ...

(American Society of Civil Engineering (ASCE), 2009-11)In many tunneling and excavation projects, free-field vertical ground movements have been used to predict subsidence and empirical limits have been employed to evaluate risk. Validity of such approaches given the reality ...
-
(Bentham Science Publishers, 2009)A spatial information system (SIS) is critical to the hosting, querying, and analyzing of spatial data sets. The increasing availability of three-dimensional (3D) data (e.g. from aerial and terrestrial laser scanning) and ...
-
(American Society of Civil Engineering (ASCE), 2009-07)Despite tremendous advances by women in the natural and applied sciences, where in selective fields women have surpassed men in the earning of doctoral degrees for more nearly 20 years, female enrollment levels in engineering ...
-
(Elsevier, 2009-12)The determination of the natural frequencies and mode shapes of structures requires an analytical, semi-analytical or numerical method. This paper presents a new semi-analytical approach to determine natural frequencies ...
-
(Elsevier, 2009-08)This work gives a semi-analytical approach for the dynamic analysis of beams and plates rest-ing on an elastic half-space with inertial properties. Such calculations have been associated with significant mathematical ...
