About the Edition

The problem of loss of stability of marine vehicles under cross track en-or control in the presence of mathematical versus actual system mismatch is analyzed. Emphasis is placed on studying the response of the system after initial loss of stability of straight line motion. Center manifold reduction and integral averaging techniques are used in order to study the bifurcations to periodic solutions and stability of the resulting limit cycles. Numerical integrations are utilized to confirm the theoretical results and to establish regions of asymptotic stability. The methods used in this work demonstrate the significance of nonlinear terms in assessing the final response of the system...

Path Planning and Control The basic framework of Path Planning and Control starts with programming an objective for the autonomous vehicle to achieve. To accomplish this task, the machine must choose a path and adjust to obstacles, terrain, and changing conditions in order to reach its destination safely. The general framework adopted leads to integrated solutions to TC-PF problems that unfold in three steps: 1) Generation of Deconflicted Trajectories for a group of vehicles, 2) Path Following for each vehicle along its assigned path, and 3) Coordination of the relative motion of the vehicles along their paths, so as to guarantee deconfliction.

Dynamic instability in the mechanics of elastic structures is a fascinating topic, with many issues still unsettled. Accordingly, there is a wealth of literature examining the problems from different perspectives (analytical, numerical, experimental etc.), and coverings a wide variety of topics (bifurcations, chaos, strange attractors, imperfection sensitivity, tailor-ability, parametric. Accurate path control of surface ships and underwater vehicles along prescribed geographical paths is a basic problem that is becoming increasingly important, par-ticularly as the missions of ocean vehicles become more complicated with strict requirements for performance. In order for a control .

It is assumed that the Hopf’s transversality condition is violated and certain other conditions prevail. In one of the cases, the system exhibits a cusp shape bifurcation path which exists for either positive or negative values of the system by: 6.

A., "On the Nonlinear Dynamics of Pursuit Guidance for Marine Vehicles," submitted for publication to the J. of Ship Research, A new method is proposed for analyzing the nonlinear dynamics and stability in lane changes on highways for tractor-semitrailer under rainy weather. Unlike most of the literature associated with a simulated linear dynamic model for tractor-semitrailers steady steering on dry road, a verified 5DOF mechanical model with nonlinear tire based on vehicle test was used in the lane change simulation.

Numerical results show a flow transition scenario with two Hopf bifurcations B 1 and B 2, occurring in critical Reynolds numbers Re c1 y Re c2, respectively. Fundamental frequencies ω 1 and ω 2, and super harmonic combinations of both develop as the Reynolds number increases from a laminar to higher transitional flow regime.

In the first, a linearly increasing path deviation is observed, whereas in the second the loss of stability is accompanied by the generation of self-sustained oscillatory motions around the commanded path.

Nonlinear analysis reveals the occurrence of both static and Poincaré-Andronov-Hopf bifurcations. The nonlinear dynamic responses and stability of marine vehicles are investigated when they are excited by regular waves.

When the vehicles are under the condition of a two-to-one internal or autoparametric resonance in which the natural frequency of the pitch mode is twice that of the roll mode, they may exhibit large-amplitude responses in an indirectly excited mode by the direct excitation.

The tumor suppressor protein p53 is a critical hub in the comprehensive transcriptional network that inhibits the growth of cells after acute stress stimulation. In this paper, an integrated model of the p53 signaling pathway in response to DNA damage is proposed and the p53 stability and oscillatory dynamics are analyzed.
