this paper reviews the current literature examining the pervasive symptom of fatigue experienced in three of the most common degenerative neurological conditions: multiple sclerosis (ms), parkinson’s disease (pd) and post-polio syndrome (pps). the existing literature can be considered under four headings definition and prevalence, type, cause, impact of fatigue. fatigue is a common symptom in d...

local scouring around bridge piers is a natural phenomenon caused by the erosive process of flowing stream on alluvial beds. the 3d flow field around bridge piers interacting with the bed materials increases complexity of local scour process. the local scour depth develops in accelerated flows and if it is not predicted correctly, the bottom level of local scour hole will exceed the original le...

this paper presents a finite element analysis and its related experimental test of corrugated steel web beams subjected to fatigue loading. a particular focus in this study was set on the fatigue failure arising from the web-to-flange welded joint of the corrugated steel web beam. a detailed three-dimensional finite element model which explicitly includes the geometry of the web-to-flange welds...

Di erential Power Analysis (DPA) on smart-cards was introduced by Paul Kocher [11] in 1998. Since, many countermeasures have been introduced to protect cryptographic algorithms from DPA attacks. Unfortunately these features are known not to be e cient against high order DPA (even of second order). In these paper we will rst describe new specialized rst order attack and remind how are working hi...

Increasingly large numbers of people communicate today via electronic means such as email or news forums. One of the basic properties of the current electronic communication means is the identiication of the end-points. However, at times it is desirable or even critical to hide the identity and/or whereabouts of the end-points (e.g., human users) involved. This paper discusses the goals and des...

The undergraduates' graduation design (thesis) of independent colleges is an important practice link in teaching program and a main course on the training of talents. In order to further enhance the quality of the undergraduates' graduation design (thesis) of independent colleges, common problems of teaching link such as lack of administration systems, irregular guidance of teachers and inheren...

The increasing availability of highly caffeinated beverages, including energy drinks, in the United States has resulted in a rise in consumption by children and adolescents. In addition, there is mounting evidence that these products are often consumed by youth for their perceived fatigue-mitigating and mood- or performance-enhancing effects. Although such perceptions by children and adolescent...
