Theory of entropic security decay: The gradual degradation in effectiveness of commissioned security systems
… its continued efficacy (steady state) or its degradation over time. The purpose of this multi-phase study was to develop the concept and define the term entropic security decay. Phase one presented documentary benchmarks for security decay. This phase was broken into three stages; stage one …

A gradient-damage theory for quasi brittle fracture
… at the onset of damage. Instead there is a gradual degradation of the strength of the material, which is the result of microscale decohesion/damage micromechanisms. In this thesis we discuss the formulation of our gradient-damage theory for quasi-brittle fracture using the virtual-power …

Distributed associative memory
… simultaneously. Statistical inference ensures gradual degradation of the performance as an associative memory is overloaded. Since many definitions of associative memory capacity rely on the existence of catastrophic failure a new definition of capacity is provided. In spite of some …

Development of Carbon-Based, Controlled-Release Soil Ameliorants Through Chemical Pathways
… revealed that washed CBCRFs exhibited more gradual degradation profiles, consistent with chemical stabilization rather than mere physical adsorption. Collectively, these results confirm that the CCT® process effectively carbonizes diverse lignocellulosic residues and produces …

Synthetic Studies Towards Mescengricin
… Unfortunately, the reaction stalled at 336 and gradually degraded upon increasing the reaction time. Next, 336 was subjected to acidic and basic conditions, however, this led to the reformation of 334 and heating the reaction led to gradual degradation. The second attempt focused on the …

A STUDY OF THE THERMAL CYCLING PERFORMANCE OF SOLDER JOINTS IN AREA ARRAY PACKAGING
… quality of the electronic component and system. Gradual degradation of the electronic components decreases efficiency of the system, and lack of reliability can lead to a significant loss. Efforts at achieving better quality and reliability of electronic components involve the inspection of …

Developing a spectroscopy-based high throughput assay for anthocyanin content in corn
… However, anthocyanins are susceptible to gradual degradation when exposed to certain food processing techniques or even due to prolonged/improper storage of food products that contain them. Although chemical assays to determine total anthocyanin content (TAC) exist, they are cumbersome, …

Log-Driven Robust Anomaly Detection and Root Cause Localisation for Distributed Computing Systems
… normal and abnormal activities and reveal gradual degradation trends that appear before failure, which is useful for early warning. The second contribution, LogAR, addresses robustness to logging noise and wording variation. LogAR couples semantic vectorisation of messages with an …

Dating Death: Forensic taphonomy and the postmortem interval
… specific phenomenon. Human hair exhibited a gradual degradation over time but this was dependent on the characteristics of the burial environment. Decompositional changes included colonisation by fungi, erosions to the cortical surface and formation of tunnels and breaks to the hair shaft. …

Delamination damage of carbon fiber-reinforced polymer composite laminates under cyclic shear-induced loading conditions
… for all the loading cases. A normalized gradual degradation rule was used to present the degradation for interlaminar shear strength ( ), penalty stiffness ( ) and the critical Mode-II energy release rate ( ) which cover the wide range of interlaminar failure mode from wear PTTA out to …

Effect of cooling rate and stacking sequence on the fatigue behavior of notched quasi-isotropic APC-2 laminates
… Fast cooled specimens of layup A showed a gradual degradation in the modulus till failure while slow cooled specimens of the same layup showed a more drastic reduction as they approached failure. No such distinguished behavior was observed in the specimens of layup B. Scanning Electron …

Phosphorylation of polyglycans, especially glycogen and starch
… branched α-1,4 glucan chains. Synthesis and degradation of transitory starch and of glycogen are accomplished by a set of enzymatic activities that to some extend are also similar in plants and animals. Chain elongation, branching, and debranching are achieved by synthases, branching enzymes, …
