A scanning cavity microscope [PDF]

open access: yesNature Communications, 2015
AbstractImaging the optical properties of individual nanosystems beyond fluorescence can provide a wealth of information. However, the minute signals for absorption and dispersion are challenging to observe, and only specialized techniques requiring sophisticated noise rejection are available.

Studies on mechanical behavior of glass epoxy composites with induced defects and correlations with NDT characterization parameters [PDF]

open access: yes, 2007
Degradation in mechanical properties (compression, flexural and ILS) of glass epoxy composite laminates with induced defects (simulating delaminations) was studied. The defects were characterized by using the A-scan ultrasonic pulse-echo technique.

Standardisation in Ultrasonography: Principle and Diagnostic Significance

open access: yesActa Medica, 2004
Disadvantage of ultrasonography is its dependence on subjective assessment of displayed images. The way how to minimize both intraobserver and interobserver differences is creation of standard conditions for examination including a quantitative approach ...

Craniolacunia in A neonate; A clinical and CT scan illustrative case report

open access: yesClinical Case Reports, 2021
Neural tube defects can be accurately diagnosed prenatally. Every effort must be made to get this and its associations with Craniolacunia right, especially in low‐resource settings.

A scan for new N=1 vacua on twisted tori [PDF]

open access: yes, 2009
We perform a systematic search for N=1 Minkowski vacua of type II string theories on compact six-dimensional parallelizable nil- and solvmanifolds (quotients of six-dimensional nilpotent and solvable groups, respectively).

Ultrasonic characterization of defective porcelain tiles

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2012
The aim of this work is the optimization of ultrasonic methods in the non-destructive testing of sintered porcelain tiles containing defects. For this reason, a silicon nitride ball, carbon black and PMMA (Polymethylmethacrylate) were imbedded in ...

Procedural Point Cloud Modelling in Scan-to-BIM and Scan-vs-BIM Applications: A Review

open access: yesISPRS International Journal of Geo-Information, 2023
Point cloud processing is an essential task in many applications in the AEC domain, such as automated progress assessment, quality control and 3D reconstruction. As much of the procedure used to process the point clouds is shared among these applications,

Tracking the built status of MEP works: Assessing the value of a Scan-vs-BIM system [PDF]

open access: yes, 2014
Mechanical, electrical, and plumbing (MEP) works constitute a large portion of construction costs and thus need to be appropriately tracked. Assessment of the built status of MEP works in construction projects is however typically limited to ...
