Crystal structure and Hirshfeld surface analysis of (2E)-3-(3-bromo-4-fluorophenyl)-1-(3,4-dimethoxyphenyl)prop-2-en-1-one
2018
The title compound is constructed from two aromatic rings (3-bromo-4-fluorophenyl and 3,4-dimethoxyphenyl), which are linked by a C=C—C(=O)—C enone bridge and form a dihedral angle of 17.91 (17)°. In the crystal, molecules are linked by C—H⋯O hydrogen bonds enclosing rings of (14) graph-set motif to form layers parallel to (10).
Integration Data Model of the Bathymetric Monitoring System for Shallow Waterbodies Using UAV and USV Platforms
2022
Changes in the seafloor relief are particularly noticeable in shallow waterbodies (at depths up to several metres), where they are of significance for human safety and environmental protection, as well as for which the highest measurement accuracy is required. The aim of this publication is to present the integration data model of the bathymetric monitoring system for shallow waterbodies using Unmanned Aerial Vehicles (UAV) and Unmanned Surface Vehicles (USV). As part of this model, three technology components will be created: a hydroacoustic and optoelectronic data integration component proposed by Dąbrowski et al., a radiometric depth determination component based on optoelectronic data u…
Activated carbon from hydrolysis lignin: Effect of activation method on carbon properties
2022
This study presents the effects of different activation methods to produce activated carbon from the hydrolysis lignin. Pretreatment of the feedstock with common mineral acids (HCL, HNO3, and H3PO4), different steam rates for physical activation, and different chemical activating agents (ZnCl2, Na2CO3, and KOH) for chemical activation were investigated. The pretreated biomass was carbonized and activated in one-stage process and the surface characteristics, such as total pore volume, pore size distribution and specific surface area, were investigated. The results showed that the activated carbon surface properties were not greatly affected by acid pretreatment. Brunauer-Emmett-Teller (BET) …
Status and Prospects of Kanki : An Open Source Cross-Platform Native iRODS Client Application
2016
The current state of development of project Kanki is discussed and some prospects for future development are laid out with reflection on the results of the research IT infrastructure project at the University of Jyväskylä. Kanki is a crossplatform native iRODS client application which was introduced to the iRODS community at the iRODS Users Group Meeting in 2015, and later released as open source. A total of 9 releases have been made, from which the latest 6 have been available in addition to the source code as pre-built binary packages for x86-64 CentOS Linux 6/7 and OS X 10.10+. The Kanki build environment at the University of Jyväskylä is running out of Jenkins continuous integration for…
Development of a Native Cross-Platform iRODS GUI Client
2015
This paper describes activities on the research IT infrastructure development project at the University of Jyväskylä. The main contribution is a cross-platform iRODS client application with a rich graphical user interface. The client application is fully native and builds from a single C++ codebase on all of the platforms on which iRODS 4.0 is supported. The application has a responsive UI with native look & feel and enables drag & drop integration to the desktop. This is made possible by basing the development of the client application on top of the Qt 5 framework and an object-oriented C++ framework for iRODS which is being developed with the client application. The objectoriented framewo…
Aesthetic Appeal and Visual Usability in Four Icon Design Eras
2016
Technological artefacts express time periods in their visual design. Due time, visual culture changes and thus affects the design of pictorial representations in technological products, such as icons in user interfaces. Previous research of temporal aspects in human-computer interaction has been focusing on particular interaction situations, but not on the effects of design eras on user experience. The influence of icon design styles of different eras on aesthetic and usability experiences was studied with the method of primed product comparisons. Affective preferences and their processing times were analysed in order to examine visual usability in terms of semantic distance and aesthetic a…
FPI Based Hyperspectral Imager for the Complex Surfaces : Calibration, Illumination and Applications
2022
Hyperspectral imaging (HSI) applications for biomedical imaging and dermatological applications have been recently under research interest. Medical HSI applications are non-invasive methods with high spatial and spectral resolution. HS imaging can be used to delineate malignant tumours, detect invasions, and classify lesion types. Typical challenges of these applications relate to complex skin surfaces, leaving some skin areas unreachable. In this study, we introduce a novel spectral imaging concept and conduct a clinical pre-test, the findings of which can be used to develop the concept towards a clinical application. The SICSURFIS spectral imager concept combines a piezo-actuated Fabry–Pé…
Variables cognitives i factors de personalitat dels subjectes amb millor control d’una Interfície Cervell Computadora
2022
Objectiu :La interrelació entre l’humà i la màquina en una tasca amb una Interficie Cervell-Computadora ( BCI de les sigles en anglès) es especialment transcendental. Hi ha subjectes incapaços d’aprendre a manipular-la( Illiteracy). El present treball analitza la influència del tipus de paradigma de control , les habilitats atencionals , els trets de personalitat i la resposta d’afrontament de la resposta davant el fracàs a l'hora d’utilitzar-la. Mètode: Hem emprat dues mostres de 89 i 191 estudiants de 1er i 2n curs de la Universitat de València en dos estudis consecutius els anys 2016 i 2017. S’han aplicat test de personalitat i qüestionaris sobre activitats rutinàries, avaluació atencion…
Molecular mechanics models for the image charge, a comment on “including image charge effects in the molecular dynamics simulations of molecules on m…
2017
We re-investigate the image charge model of Iori and Corni (Iori and Corni, J. Comput. Chem. 2008, 29, 1656). We find that a simple symmetrization of their model allows to obtain quantitatively correct results for the electrostatic interaction of a water molecule with a metallic surface. This symmetrization reduces the magnitude of the electrostatic interaction to less than 10% of the total interaction energy. © 2017 Wiley Periodicals, Inc.
