A swimmer falls overboard in an equilateral triangle lake in a fog. If the edge length of the triangle is 1, what is the shortest length swimming path that ensures the swimmer will reach the shore? Swimming one unit straight in any direction certainly reaches the shore. The problem was originally posed in 1963. Besicovitch showed shortly afterward that a 3-link chain of length 3 √ 21/14 = 0.981...

The author has attempted to highlight this link by demonstrating an association between postural alignment of the scapula and a structural alteration in pectoralis minor muscle length. Connections between pectoralis minor muscle length and pathomechanical alterations in scapular kinematics,1 between pain and impairment and alterations in scapular kinematics,2 and even directly between postural ...

This paper starts with developing kinematic and dynamic model of a snake shape robot in serpentine locomotion and finishes with actual experimentation. At the beginning the symmetrical and unsymmetrical serpenoid curves are introduced. Kinematics and dynamics of a snake robot on flat and inclined surfaces are obtained for a general n-link robot. SimMechanics toolbox of MATLAB software is employ...

Finite type invariants of knots or links can be defined combinatorially using only link projections in S. In this setting it can be seen that every Jones-type polynomial invariant (quantum invariants) is equivalent to a sequence of finite type invariants. See [B2, BN] and references therein. Although Vassiliev’s original approach to finite type knot invariants ([V]) rests on topological foundat...

from the time that civil engineers have used steel in building structures, they tried to increase its strength so as to produce more economic and lighter structures by using more elegant sections. increase of steel strength is not always useful for all members of a steel structure. in some members under certain conditions, it is needed to reduce the strength as much as possible to improve the b...

Full-length or nearly full-length RNA genome sequences for 98 rhinovirus (RV) A isolates (from the Enterovirus genus of the Picornaviridae family), representing 43 different genotypes, were resolved as part of ongoing studies to define RV genetic diversity and its potential link to respiratory disease.

The widespread installation of millions of Infrared Data Association (IrDA) infrared (IR) ports in mobile devices for wireless communication applications necessitates for throughput performance optimization of the IR links at the IrDA link access protocol (IrLAP) link layer. For IrDA connectivity, link-layer throughput optimization is important for any line bit-error rate (BER). The paper provi...

As the Internet becomes increasingly heterogeneous, the issue of congestion avoidance and control becomes ever more important. And the queue length, end-to-end delays and link utilization is some of the important things in term of congestion avoidance and control mechanisms. In this work we continue to study the performances of the New-AIMD (Additive Increase Multiplicative Decrease) mechanism ...
