Perception of added airflow resistance in humans
Respiration Physiology, 1966Abstract Detection of added airflow resistance was measured in various conditions with human subjects and thresholds for perception of resistances compared. Thresholds for perception were markedly different in some conditions of the experiments when expressed in terms of the absolute amount of resistance added. However, when thresholds were expressed

Intrusion-resistant ad hoc wireless networks
MILCOM 2002. Proceedings, 2003The subversion of the routing function in ad hoc networks can lead to denial of network service. Ad hoc networks are particularly vulnerable to denial of service (DoS) attacks launched through compromised wireless routers or "intruders". Current routing algorithms for such networks contain few, if any, mechanisms for providing robust network operation ...

Silicon-Added Bilayer Resist (SABRE) System
SPIE Proceedings, 1988A new silylated resist process has been developed that provides the advantages of trilayer photoresist processing in a simpler bilayer format. In this new process, silicon for oxygen plasma etch resistance is added to a conventional photoresist layer after it has been exposed and developed.

Dissolution-resistance of glass-added hydroxyapatite composites
Metals and Materials International, 2009Hydroxyapatite (HA) has generated a great deal of interest as a promising implant material. However, its poor mechanical properties induced by severe dissolution in biological milieu limit medical applications and lead to clinical failure. In this study, HA ceramics with 30P2O5-30CaO-40Na2O glass (1.0 wt.% and 2.5 wt.%) were prepared to improve the ...

Simulation of Added Resistance in High Waves
Volume 11: Prof. Robert F. Beck Honoring Symposium on Marine Hydrodynamics, 2015A vessel traveling across the sea experiences waves. The waves produce forces on the vessel resulting in added resistance. The forces are caused by the combination of wave and vessel motion. A variety of methods for prediction of added resistance in waves exists. The complexity and accuracy varies significantly. This paper focuses on numerical solution

Added Resistance of Moonpools in Calm Water
Volume 6: Nick Newman Symposium on Marine Hydrodynamics; Yoshida and Maeda Special Symposium on Ocean Space Utilization; Special Symposium on Offshore Renewable Energy, 2008The additional ship resistance due to water oscillations in an open moonpool as constructed in drillships can be obtained through model tests. The oscillation has a dominant frequency and character, and the amplitude increases with forward speed. The resonant oscillation mode can be piston or sloshing.

Longitudinal Changes in Insulin Resistance, Cognition, and AD Biomarkers across the AD Continuum
Alzheimer's & Dementia, 2023AbstractBackgroundTo determine if 3‐year changes in serum insulin resistance (IR) were related to changes in brain volume and glucose uptake, cognition, and CSF biomarkers in cognitively unimpaired and impaired older adults.MethodAlzheimer’s Disease Neuroimaging Initiative data was downloaded for 275 aged adults (55‐89 years).

Added Resistance of Ships in Waves
Journal of Hydronautics, 1978A new method is presented for computing the added resistance of a ship advancing at constant mean speed and heading in regular waves. It is shown that the added resistance, even though it is a second-order quantity, can be expressed as a product of first-order terms that are all computed by computer programs presently in use for predicting the linear ...

Resisting flooding attacks in ad hoc networks
International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II, 2005Mobile ad hoc networks will often be deployed in environments where the nodes of the networks are unattended and have little or no physical protection against tampering. The nodes of mobile ad hoc networks are thus susceptible to compromise. The networks are particularly vulnerable to denial of service (DOS) attacks launched through compromised nodes ...

Prediction of added resistance using genetic programming
Ocean Engineering, 2018Abstract In recent years, the increasing demand for a reduction of carbon emission has made hydrodynamic design and the optimization of hull design more important. For appropriate hydrodynamic design, the added resistance needs to be predicted. However, as existing methods including computer simulations or experiments require considerable amounts of ...
