Cone penetration testing (CPT) in Antarctic firn: an introduction to interpretation [PDF]

Journal of Glaciology, 2014
AbstractCommercial cone penetration testing (CPT) equipment was adapted to allow penetrative testing in hard polar firn to depths of 10 m. The apparatus is hydraulically driven, rate-controllable and able to penetrate firn with a resistance of 10 MPa. It can be mounted on many types of typical polar vehicles, requiring connection to only hydraulics and

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Deterministic and Probabilistic Analyses of the Bearing Capacity of Screw Cast in Situ Displacement Piles in Silty Soils as Measured by CPT and SDT

The Baltic Journal of Road and Bridge Engineering, 2023
The bearing capacity of screw cast in situ displacement piles is mostly unexplored. There is also insufficient research on piles in silty soils. Therefore, five cone penetration tests (CPT) and one piezocone penetration test (CPTu) using direct methods ...

Interest and effort in learning and performance

British Journal of Educational Psychology, EarlyView.
Abstract Background Interest and effort are key motivational constructs in educational psychology, yet their interplay in learning remains underexplored. Building on Dewey's (Interest and effort in education, 1913) view that effort complements interest in fostering academic achievement, this research examines their relationship across different ...

Layered effects on soil displacement around a penetrometer [PDF]

, 2017
The interpretation of cone penetration test (CPT) data is important for the in-situ characterisation of soils. Interpretation of CPT data remains a predominately empirical process due to the lack of a rigorous model that can relate soil properties to ...

Soil classification based on cone penetration test (CPT) data in Western Central Java [PDF]

AIP Conference Proceedings, 2018
This study presents a modified friction ratio range for soil classification i.e. gravel, sand, silt & clay and peat, using CPT data in Western Central Java. The CPT data was obtained solely from Soil Mechanic Laboratory of Jenderal Soedirman University that covers more than 300 sites within the study area.

Decline of Visual Function and Risk of Legal Blindness With Age in RPGR‐Associated Retinal Degeneration: A Multicenter Study

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background This retrospective multicenter longitudinal analysis analysed the loss trajectory of best recorded visual acuity (BRVA) and Goldmann visual field (GVF) in RPGR‐associated retinal degeneration (RPGR‐RD). Methods Patients with genetically confirmed RPGR‐RD were classified into rod‐cone (RC), cone/cone‐rod (CR) and female‐carrier ...

Investigation of Solution Accuracy in PFEM Simulations Using Benchmark Problems

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT The simulation of large topological changes, such as those occurring in Cone Penetration Testing (CPT) and vibratory pile driving, remains a major challenge in computational geomechanics. Excessive mesh distortions render classical approaches like the Finite Element Method (FEM) unsuitable, emphasizing the need for alternative methodologies ...
