This paper describes the development and implementation of a dynamic positioning system for Remotely Operated underwater Vehicles (ROVs) which is based on a mechanical Passive Arm (PA) for position measurement. The system, named DPSROV, is suited for tasks which require precise positioning within a limited range around a working site. The DPSROV was conng-ured aiming at easy installation in mos...

Using far-infrared 240μm and near-infrared K band data from the COBE/DIRBE instrument, we model the Galactic stellar and dust distribution. Making the assumption that the Galaxy is transparent in the 240μm band, the dust emission is modeled using the following components: a warped exponential disk of scale length 0.26R⊙, a spiral arm component as mapped by HII regions, and a feature coinciding ...

This study provides a design procedure for the self tuning adaptive control of a CD arm controller. The inputs are the forces of the mechanical actuators while the outputs are related to the tracking accuracy of the arm. The data was measured in closed loop, and then through a two-step procedure converted to open loop equivalent data the inputs are highly colored. Rely on the obtained model, th...

In this paper, I examine the effect of introducing heterogeneity between players in models of strategic experimentation. I consider a two-armed bandit problem with one safe arm and a risky arm. There are two players and each has an access to such a bandit. A player using the safe arm experiences a safe flow payoff . The risky arm can either be good or bad. A bad risky arm is worse than the safe...

Rule-based formalisms are ubiquitous in computer science. However, a difficulty that arises frequently when specifying or programming the rules is to determine which effects should be propagated by these rules. In this paper, we present a tool called ARM (Automatic Rule Miner) that generates rules for relations over finite domains. ARM offers a rich functionality to provide the user with the po...

This paper presents the NEURARM, a novel robotic platform specifically designed for performing joint experiments between neuroscience and robotics. The NEURARM replicates the main functions and characteristics of the human arm during the execution of planar movements for reaching and catching a moving object. The NEURARM is a 2-d.o.f. planar robotic platform actuated by means of four linear hyd...

We present a photometric study of the neglected open cluster Berkeley 53. We derived its fundamental parameters, such as the age, the interstellar reddening, and the distance from the Sun, based on BV photometry combined with near-infrared JHK S data. The structure and the mass function of the cluster were also studied and the total number of members and the total mass were estimated. The clust...

This paper details the investigation into assessment of a commercially available photoreceiver. A critical analysis of performance evaluation of the photoreceiver in relation to its Responsivity and Time Response are carried out. A standard Helium-Neon laser operated at 632.8nm was used as the stimulating light source in order to achieve the desired measurements. The measurements clearly show h...
