In recent years, ultraviolet (UV) bands have received increasing attention from the ocean colour remote sensing community, as they may contribute to improving atmospheric correction and inherent optical properties (IOPs) retrieval. However, most satellite sensors do not UV bands, accurate retrieval of reflectance (Rrs) data is still a challenge. order address this problem, study proposes hybrid...

BACKGROUND The 92 capsular serotypes of Streptococcus pneumoniae differ greatly in nasopharyngeal carriage prevalence, invasiveness, and disease incidence. There has been some debate, though, regarding whether serotype independently affects the outcome of invasive pneumococcal disease (IPD). Published studies have shown variable results with regard to case-fatality ratios for specific serotypes...

The forced oscillation technique (FOT) is gaining clinical acceptance, facilitated by more commercial devices and clinical data. However, the effects of variations in testing protocols used in FOT data acquisition are unknown. We describe the effect of duration of data acquisition on FOT results in subjects with asthma, chronic obstructive pulmonary disease (COPD) and healthy controls. FOT data...

Several molecular assays to detect resistance to Rifampin, the Fluoroquinolones, and Aminoglycosides in Mycobacterium tuberculosis (M. tuberculosis) have been recently described. A systematic approach for comparing these assays in the laboratory is needed in order to determine the relative advantage of each assay and to decide which ones should be advanced to evaluation. We performed an analyti...

This paper describes a new system to automatically generate, evaluate and execute assembly sequences. With the commands generated by the system, robots are enabled to assemble complex products without explicit robot programming. Our approach uses CAD-models, symbolic spatial relations and a robot work cell description as input. The system provides a user-friendly interface to define the goal st...

Social interaction between humans takes place in the spatial dimension on a daily basis. We occupy space for ourselves and respect the dynamics of spaces that are occupied by others. In human-robot interaction, the focus has been on other topics so far. Therefore, this work applies a spatial model to a humanoid robot and implements an attention system that is connected to it. The resulting beha...

We studied the electronic energies and phonon frequencies of polydiacetylene 4-BCMU thin films at high pressures up to 50 kbar using Raman scattering under preresonant and resonant conditions. Pressure-induced changes in the resonant Raman scattering (RRS) include (1) hardening of the most strongly coupled phonon frequencies, (2) dispersion of the RRS frequencies with the laser excitation coL, ...

We have developed a robust qualitative method for robot exploration, mapping, and navigation in large-scale spatial environments. An environment is large-scale if its spatial structure is at a signi cantly larger scale than the sensory horizon of the observer. Experiments with a simulated robot in a variety of 2-D environments have demonstrated that our method can build an accurate map of an un...

An ACT-R cognitive model is used to control the spatial behavior of a virtual robot that is embedded in a three-dimensional virtual environment, implemented using the Unity game engine. The environment features a simple maze that the robot is required to navigate. Communication between ACT-R and Unity is established using a networkbased inter-operability framework. The ability of the robot to l...

It is essential for successful human-robot interaction that the robot is able to both qualitatively understand the intended meaning of the human’s utterances and to react to them in the continuous real world. In this paper we present a number of novel techniques that collectively allow a robot to interpret and execute spoken commands describing manipulation goals involving qualitative spatial c...
