Postural control can be defined as the control of the body’s position in space for the purposes of balance and orientation [1]. A definition of balance is the ability to maintain or return the body's centre of gravity within the limits of stability that are determined by the base of support (i.e., the area of the feet) [2]; while spatial orientation defines our natural ability to maintain our b...

Tracking a trajectory is a demanding task when flexible robots are being considered. To tackle this problem this paper introduces a model-based differential geometric approach. In the design process a control structure will be proposed that allows the choice of an arbitrary dynamic response of the controlled system within certain limits. The result is a complex feedback structure with inherent ...

The emergence of budget airlines, the advent of new sales channels, the disappearance of traditional fare-class fences, and other on-going changes in the airline industry pose serious challenges to traditional revenue management models, which make some rigid and unrealistic assumptions. One of these is that passengers who do not get the fare they want book and travel on other airlines or do not...

Abstract Fluid dynamic equations are used to model various phenomena arising from physics, engineering, astrophysics, geophysics. One feature is that they take place at different time and length scales it important understand which occur according the use of single or interactions them. From a mathematical point view, these physical behaviours give rise singular limits and, consequently analysi...

This communication shows that the concept of Brownian trapping with drift can be applied to improve quantitative molecular measurements. It has the potential to combine the robustness of end-point spatially resolved readouts, the ultrasensitivity of digital single-molecule measurements, and the large dynamic range of qPCR; furthermore, at low concentrations of analytes, it can provide a direct ...

the flowering phase of apple trees is the most critical step in relation with low temperatures and frost events. therefore, forecasting the time of flowering is important. if a model can predict the exact time of flowering, it would be feasible to care for flowers agianst late spring freezing (lsf). in this study, we evaluated three temperature-base chilling models namely: chilling hours (ch), ...

This book gathers together our joint work (through 2008) on the closely connected topics of repeated games and reputation effects, along with related papers on more general issues in game theory and dynamic games. Since this work studies, among other things, the way that long-run interactions facilitate cooperation, and our collaboration began in 1980, it seems fitting that the papers appear in...

In this paper, we present FBAC (Flexible Bound Admission Control) algorithm using softness profile to reduce handover blocking probability over WLAN and WAAN (Wide Area Access Network). FBAC algorithm utilizes dynamic resource allocation scheme to decrease the blocking probability of vertical handover connections within the limited capacity of system. Based on FBAC algorithm, we derive the hand...
