Material Tests and Mesoscale Computer Model for Ballistic Impact on Carbon Fiber Composite
Two-dimensional (unidirectional) and 3-D woven carbon fiber reinforced plastic (CFRP) panels were produced by Albany Engineered Composites. Coupons were machined from the laminates for various mechanical tests in tension, torsion, and delamination.

Ballistic and numerical simulation of impacting goods on conveyor belt rubber
Impact loading is an important process in the transport industry as it causes wear and failure of critical components. Conveyor belts are of particular importance as they are used in practically every industry where large quantities of goods are moved over short (<10 m) or long distances (>1 km).

Computational Modeling of Decision Making Enhances the Adversity Researcher's Toolbox
Abstract Over the past decades, there has been major progress in our understanding of how adversity influences cognitive abilities and strategies. However, most of this research is based on raw performance, such as response times and accuracy. These measures are informative about decision‐making outcomes but tell us little about cognitive processes. In

Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

A new stopped‐flow instrument allows kinetic measurements of reactions 10 milliseconds after initiating them by mixing in a flow cell inserted into a standard NMR probe and spectrometer. High‐speed video, pressure and NMR line‐shape data are used to characterise mixing and stopping, and a protodeboronation reaction with a 5‐millisecond half‐life used ...

Experimental verification of numerical simulation of projectile impact on ballistic shields
Abstract In this work, the author presents experimental verification of numerical simulation of projectile impact on constructional shields. The experimental tests were performed at a unified test stand to investigate ballistic resistance of materials in field conditions.

Muscle Mitochondrial Oxidative Capacity and Cognitive Decline Over up to a Decade: Sex Differences
Skeletal muscle mitochondrial oxidative capacity is linked to cognition and predicts cognitive decline primarily in men. Underlying mechanisms appear to differ by sex, likely through a metabolic‐drive pathway in men and a hematologic‐inflammatory pathway in women.

Recent Progress and Future Prospects of LWIR T2SL InAs/GaSb Detectors on GaAs
InAs/GaSb LWIR type‐II superlattices (T2SLs) on GaAs substrates are cost‐effective and offer higher yield. However, due to a relatively large lattice mismatch, a high density of threading dislocations is created, which is detrimental to device performance.

Modeling and Simulation of Ballistic Impact
Numerical simulations are increasingly becoming an important tool to obtain efficient designs of protective structures, and the existing literature shows that many phenomena can be accurately described by standard methods and models. This thesis, specifically, focuses on novel methods of modeling and simulating ballistic impact.

Buried Unstrained Germanium Channels: A Lattice‐Matched Platform for Quantum Technology
ABSTRACT Strained germanium (ε$\varepsilon$‐Ge) and strained silicon (ε$\varepsilon$‐Si) buried quantum wells have enabled advanced spin‐qubit quantum processors. However, in the absence of suitable lattice‐matched substrates, ε$\varepsilon$‐Ge and ε$\varepsilon$‐Si are deposited on defective, metamorphic SiGe buffers, which may impact device ...
