Comparison of Deflection Patterns of Simply Supported and Fixed Supported Beam Structures [PDF]

open access: yes, 2018
When designing a building, the most of the important component is the roof. The selection of roofs for building depends on factors like type of building, type of foundation, roofing materials, roof loads, the climate, economy, the availability of ...

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Prestress Loss Distributions along Simply Supported Pretensioned Concrete Beams

open access: yesElectronic Journal of Structural Engineering, 2016
The prestressing forces in prestressed tendons undergo a process of reduction over a period of time. A common assumption is that prestress loss is constantly distributed throughout the span of a simply supported pretensioned concrete beam.

Dynamic analysis of a simply supported beam with crack [PDF]

open access: yes, 2011
The crack present in the structure changes the physical nature of it as well as changes the dynamic response towards the vibration. For the analysis the depth and location of the crack are important parameters which change the response.

Wavelet based experimental damage calibration using beam-moving load interaction model [PDF]

open access: yes, 2010
This paper presents a study of wavelet based prediction curves for the extent of damage using experimental data from the spatial domain. The methodology is illustrated through experiments on a simply supported beam traversed by a model two-axle ...
