Collision-Free Coordination of Fiber Positioners in Multi-object Spectrographs

Denis Gillet, Jean-Paul Richard Kneib, Laleh Makarem

Many ber-fed spectroscopic survey projects, such as DESI, PFS and MOONS, will use thousands of fiber positioners packed at a focal plane. To maximize observation time, the positioners need to move simultaneously and reach their targets swiftly. We have pre ...

Augmenting Learning Activities with Contextual Information Scent

Nan Li

Students often have information needs while carrying out a multitude of learning activities at universities. When information is needed for investigating a problem, the student may interrupt the work and switch to an information seeking task. As Internet c ...

A Conjoined Electron and Thermal Transport Study of Thermal Degradation Induced During Normal Operation of Multigate Transistors

A 3-D full-band particle Monte Carlo (MC) simulator, with full electron and phonon dispersion and a 2-D quantum correction is self-consistently coupled to a phonon MC simulator. The coupling entails feeding the phonon data obtained from the 3-D electrical ...

Tunable grating with active feedback

Herbert Shea, Samuel Rosset

We report on the use of capacitive self-sensing to operate a DEA-based tunable grating in closed-loop mode. Due to their large strain capabilities, DEAs are key candidates for tunable optics applications. However, the viscoelasticity of elastomers is detri ...

Metabolic modeling and experimental studies on carbon and energy metabolism of Mycobacterium tuberculosis

Muhittin Emre Özdemir

Tuberculosis is an ancient human disease affecting millions of people every year. The common causative agent, Mycobacterium tuberculosis, is a peculiar pathogen that can persist in the host tissues for decades. Many of the key attributes of M. tuberculosis ...

Immersive singularity-free full-body interactions with reduced marker set

Ronan Boulic, Daniel Raunhardt

Despite the large success of games grounded on movement-based interactions the current state of full-body motion capture technologies still prevents the exploitation of precise interactions with complex environments. The first key requirement in the line o ...
