A scheme is proposed for ground plane obstacle detection under conditions of variable camera geometry. It uses a predictive stereo matcher implemented in the PILUT architecture described below, in which is encoded the disparity map of the ground plane for the different viewing positions required to scan the work space. The research is the extension of Mallot et al's (1989) scheme for ground pla...

The indirect field oriented control method is widely used for induction motor drives. This method needs a speed sensor such as a shaft encoder not only for the speed control but also for the torque control. The application of the speed sensor reduces the sturdiness of the system and make it expensive. Therefore, a drive system without speed sensors is required. Although the direct field oriente...

As introduced in Chapter 11 (Thomson, 2015), Fair Division refers to the general problem of fairly dividing a common resource among agents having different —and sometimes antagonistic— interests in the resource. But under this general term one can actually gather a cluster of very different problems, all calling for different solution concepts: after all, one can easily figure out that we canno...

This paper concerns statistical disclosure control methods to minimize information loss while keeping small the disclosure risk from different data snoopers. This issue is of primary importance in practice for statistical agencies when publishing data. It is assumed that the sensitive data have been identified by practitioners in the statistical offices, and the paper addresses the secondary pr...

Zero-net mass-flux jet based control of flow separation over a stalled airfoil is examined using numerical simulations. Two-dimensional simulations are carried out for a NACA 4418 airfoil at a chord Reynolds number of 40,000 and angle of attack of 18 deg. Results for the uncontrolled flow indicate the presence of three distinct natural time scales in the flow corresponding to the shear layer, s...

In this paper, a closedloop strategy in the vertical plane is derived in order to determine the thrust direction of a launch vehicle in terms of velocitiestobe gained The two velocities-to-be-gained are utilized, here, for a given altitude and zero vertical speed in a specied nal time The formulation is obtained for constant gravity assumption, but it works when the velocitiesto-be-gained are o...

The "zero-position" of the shoulder joint described by Saha (1961) is recognized as a mechanical position between scapula and humerus, and the "scapular plane" is widely accepted as a mechanical plane at the shoulder joint. On the basis of biomechanical concepts of the "zero-position" and the "scapular plane", the authors designed the "zero-position" functional shoulder orthosis. This orthosis ...

In 1971 a “missing memristor” was proposed by a circuit theorist named Leon Chua as a 4 fundamental passive circuit element defined by a non-linear relationship between electric charge and magnetic flux linkage. In 2008 a research group from Hewlett-Packard led by Stan Williams claimed credit for finding this “missing memristor” based on the observation of a zero-crossing hysteresis effect. I r...

This paper describes the validation of a two-level computational scheme dedicated to PWR assembly calculations within the framework of the DRAGON v4 lattice code. The first level uses the interface current method for both the subgroup-based self-shielding and main flux calculation, with a 172-group XMAS energy discretization. The second level uses the method of characteristics preconditioned wi...

The jets in the equatorial Pacific Ocean of a realistically forced global circulation model with a horizontal resolution of 1=12:5 cause a strong loss of phase coherence in semidiurnal internal tides that propagate equatorward from the French Polynesian Islands and Hawaii. This loss of coherence is quantified with a baroclinic energy analysis, in which the semidiurnal-band terms are separated i...
