In-situ annealing characterization of atomic-layer-deposited Al2O3 in N2, H2 and vacuum atmospheres

2019

Tarkista embargo, kun artikkeli julkaistu. Atomic-layer-deposited Al 2 O 3 films can be used for passivation, protective, and functional purposes in electronic devices. However, as-deposited, amorphous alumina is susceptible to chemical attack and corrosion during manufacturing and field-use. On the contrary, crystalline Al 2 O 3 is resistant against aggressive chemical treatments and corrosion. Here, high-temperature treatments in N 2 , H 2 , and vacuum were used to crystallize alumina which exhibited different crystalline phases. The annealing process was monitored continuously in situ by measuring the film temperature and surface reflectance to understand the crystallization kinetics. Ex…

Web system to support analysis of the Tile Calorimeter commissioning

2008

This article describes the set of computer systems that support the data analysis and quality control during the Tile Calorimeter commissioning phase. The Tile Commissioning Web System (TCWS) encapsulates the steps to retrieve information, execute programs, access the outcomes, register statements and verify the equipment status. TCWS integrates different applications, each one presenting a particular view of the commissioning process. The TileComm Analysis stores plots and analysis results, provides equipment-oriented visualization, collects information regarding the equipment performance, and outlines its status in each test. The Timeline application provides the equipment status history …

Deployment of a WLCG network monitoring infrastructure based on the perfSONAR-PS technology

2014

The WLCG infrastructure moved from a very rigid network topology, based on the MONARC model, to a more relaxed system, where data movement between regions or countries does not necessarily need to involve T1 centres. While this evolution brought obvious advantages, especially in terms of flexibility for the LHC experiment's data management systems, it also opened the question of how to monitor the increasing number of possible network paths, in order to provide a global reliable network service. The perfSONAR network monitoring system has been evaluated and agreed as a proper solution to cover the WLCG network monitoring use cases: it allows WLCG to plan and execute latency and bandwidth te…

Oxygen-deficient Co3O4 submicron porous sphere films as highly active supsercapacitor electrodes

2021

Abstract Herein, we report Co3O4 films with different content of oxygen vacancies and shapes of particles for supercapacitor electrodes. Under the similar area ratio of OII peak in the XPS spectrum of oxygen elements, the specific capacitance of electrode films with hollow spongy-like particles (963 F/g under a scan rate of 5 mV/s) is 1.6 times higher than that of the electrodes with solid irregular particles (596 F/g), indicating the effect of particle shapes on electrochemical properties. The films composed of submicron porous spheres and containing highest content of oxygen vacancies exhibited the specific capacitances as high as 1700 F/g under the scan rate of 5 mV/s. By contrast, after…

Realism Score for Immersive Virtual Reality Systems and Driving Simulators

2016

International audience; Traditional 2D or 3D quality assessment methods are not sufficient to assess the realism of the outputs of a simulator/immersive virtual reality system. We propose an assessment method based on a scoring system through a new approach. The objective of this paper is to propose a score scale for any simulator or immersive display system that would represent how close to the human visual system the signals that are sent through the display are. Weighted items considered are contrast, acuity, frames per seconds, brightness, field of view and the number of color available.

Designing Touchless Gestural Interfaces for Public Displays

Nell’ultimo decennio, molti autori hanno studiato la possibilità di utilizzare le interfacce a gesti come strumento innovativo per supportare l’interazione con i computer. Inoltre, le recenti innovazioni tecnologiche hanno permesso di installare display interattivi in ambienti privati e pubblici. Tuttavia, l’interattività di tali display è spesso basata sull’uso di touchscreen, mentre tecnologie come i dispositivi Kinect-like vengono adottate molto più raramente, soprattutto se si considera l’ambito dei display pubblici. Al giorno d’oggi, l’opportunità di studiare le interfacce touchless per i display pubblici è diventata concreta, e rappresenta il campo di studio di diversi ricercatori. L’…

2019

Master's thesis Mechatronics MAS500 - University of Agder 2019 Today, process automation is the primary area of development in the shotcrete industry. Automaticshotcrete operations can yield an increase in operational efficiency and personnel safety as well asreductions in cost and environmental impact. This thesis develops a framework for automaticapplication of shotcrete using the AMV 4200H and provides an automatic spraying mode usinginteroceptive sensing. The shotcrete vehicle is equipped with a five degrees-of-freedom manipulatorand is currently operated manually. Our contributions include solving the forward kinematicsthrough the Denavit-Hartenberg convention, and the inverse kinemati…

User-Centered Design for Biomedical Literature Search User Interfaces

2019

Biomedical literature search tools are crucial resources for the work of physicians, biologists, and bioinformatics. Many of the genetic-medical diagnoses depend on the findings in these literature resources. Despite the importance and value of the information stored in these resources, the user interface (UI) implemented by such tools present several usability problems converting the query and interpretation of the information into complex and time-consuming tasks. In this sense, an user-centered design (UCD) approach can improve the usability of these UIs facilitating the interaction, analysis, and comparison of biomedical information, and, consequently, improving the productivity of prac…

Hydrogen influence on the structure and properties of amorphous hydrogenated carbon films deposited by direct ion beam

2008

Abstract The present work provides results for amorphous hydrogenated carbon (a-C:H) films grown by direct ion beam deposition method. Acetylene and its mixtures with hydrogen were used. The films were characterized by Rutherford backscattering spectrometry, elastic recoil detection, Raman spectroscopy, ellipsometry, infrared spectroscopy, and microhardness measurements. These techniques indicated that an admixture of hydrogen yields a lower deposition rate, a higher content of total and bounded hydrogen in the a-C:H films, and a lower film density. The optical and mechanical properties depend on both, hydrogen concentrations in the gas phase and in the films, and show a strong diamond-like…
