The optimisation is made by using an ES coded in Matlab (POLAND 2002) in connection with Simulink and a multi-body simulation software. The multi-body model is composed of four rigid bodies (trunk, upper arm, forearm/hand). They are connected with joints (hip, shoulder, elbow). The motion of the segments towards each other is realized with “massless motors”. The maximum tangential velocity of t...

This paper proposes a novel micro/nano scale manufacturing system using optical tweezers and chemical linkages for manufacturing twoand threedimensional micro/nanostructures. A holographic multiple trap optical tweezer system is first used to trap particles in a desired pattern. The particles are then connected to form rigid units using suitable chemistry. Connection schemes based on gold seedi...

We investigate characterizations of the Galois connection sInv–Aut between sets of finitary relations on a base set A and their automorphisms. In particular, for A = ω1, we construct a countable set R of relations that is closed under all invariant operations on relations and under arbitrary intersections, but is not closed under sInvAut. Our structure (A, R) has an ω-categorical first order th...

this study proposes a new linear approximation for solving the dynamic response equations of a rocking rigid block. linearization assumptions which have already been used by hounser and other researchers cannot be valid for all rocking blocks with various slenderness ratios and dimensions; hence, developing new methods which can result in better approximation of governing equations while keepin...

considering recent developments in earthquake engineering, researchers has detected different effects of earthquakes far and near from the fault. investigations that have been done in this area show that near fault earthquakes have shorter time period comparing far fault earthquakes and in the velocity of near fault earthquakes, there are one or more impacting pulses with a big domain and perio...

Polyamines are known to play important roles in the proliferation and differentiation of many types of cells. Although considerable amounts of polyamines are synthesized and stored in the testes, their roles remain unknown. Ornithine decarboxylase antizymes (OAZs) control the intracellular concentration of polyamines in a feedback manner. OAZ1 and OAZ2 are expressed ubiquitously, whereas OAZ-t/...

Connections of I-beam to CHS column in buildings are either simple (fin plate connection, directly welded beam connections) and flexible or rather complex rigid (external diaphragm connections). The passing-through I-beam-to-CHS connections made by laser cutting technology offer a solution that limit the amount welding enhance stiffness joint. An experimental campaign has been carried out inves...
