An analogue of the Euler top is considered for a pseudo-Euclidean space under consideration. In cases when geometric integral or area vanishes bifurcation diagrams moment map are constructed and homeomorphism class each leaf Liouville foliation determined. For arc diagram, one two possible mutual arrangement moments inertia, types singularities in preimage small neighbourhood this (analogues Fo...

to provide reliable information concerning reproductive potential of hippodamia variegata goeze and its prey (aphis fabae), their related life tables were studied under controlled laboratory conditions (at 23?c). the unprocessed data of life tables were analyzed taking the euler-lotka as the basis model. standard error of population growth parameters was calculated using the jackknife re-sampli...

parameter identification techniques are particularly attractive to determine the inertial parameters of robot manipulators and manipulated payloads. these parameters are particularly needed in implementation of a model-based controller for robot manipulators. in this paper, the inertial parameters of a manipulated rigid-body object have been estimated. the newton-euler equations will be employe...

Grandmont (1985) found that the parameter space of even the simplest, most classical models is stratified into bifurcation regions. But in such classical models all policies are Ricardian equivalent and all solutions are Pareto optimal. As a result he was not able to reach conclusions about policy relevance of his dramatic discovery. Barnett and He (1999,2002) subsequently found transcritical, ...

BACKGROUND Osteoporosis (OP) and osteoarthritis (OA) are two common musculoskeletal disorders that affect the quality of life in aged people. An inverse relationship between OP and OA was proposed four decades ago. However, the difference in microstructure of the trabecular bone of these two disorders by high-resolution MRI (HR-MRI) has not been compared. The primary objective of the study is t...

In this paper we establish passivity for the system which describes the attitude motion of a rigid body in terms of minimal three dimensional kinematic parameters In partic ular we show that linear asymptotically stabilizing controllers and control laws without angular velocity measurements follow naturally from these passivity properties The results of this pa per extend similar results for th...
