Optimization of solution-processed oligothiophene:fullerene based organic solar cells by using solvent additives
(Beilstein Institut, 2013-10)
The optimization of solution-processed organic bulk-heterojunction solar cells with the acceptor-substituted quinquethiophene DCV5T-Bu-4 as donor in conjunction with PC61BM as acceptor is described. Power conversion ...
Aspects to take into account in the application of mechanical calculation to high temperature low sag conductors
(The Institution of Engineering and Technology, 2010-05)
Reconductoring with high temperature low sag (HTLS) conductors is an alternative to the traditional uprating methods. The obtained rating increase depends on the mechanical and thermal behaviour of the conductor. In this ...
STM study on the self-assembly of oligothiophene-based organic semiconductors
(Beilstein Institut, 2011-11)
The self-assembly properties of a series of functionalized regioregular oligo(3-alkylthiophenes) were investigated by using scanning tunneling microscopy (STM) at the liquid-solid interface under ambient conditions. The ...
FTT-MA: A Flexible Time-Triggered Middleware Architecture for Time Sensitive, Resource-Aware AmI Systems
(MDPI, 2013-05)
There is an increasing number of Ambient Intelligence (AmI) systems that are time-sensitive and resource-aware. From healthcare to building and even home/office automation, it is now common to find systems combining ...
An Embedded Stress Sensor for Concrete SHM Based on Amorphous Ferromagnetic Microwires
(MDPI, 2014-11)
A new smart concrete aggregate design as a candidate for applications in structural health monitoring (SHM) of critical elements in civil infrastructure is proposed. The cement-based stress/strain sensor was developed by ...
Classifier Subset Selection for the Stacked Generalization Method Applied to Emotion Recognition in Speech
(MDPI, 2016-01)
In this paper, a new supervised classification paradigm, called classifier subset selection for stacked generalization (CSS stacking), is presented to deal with speech emotion recognition. The new approach consists of an ...
Tension and Ampacity Monitoring System for Overhead Lines
(IEEE, 2013-01-01)
Real time monitoring allows the determination of the line state and the calculation of the actual rating value. The real time monitoring systems measure sag, conductor tension, conductor temperature or weather related ...
A Novel Micro- and Nano-Scale Positioning Sensor Based on Radio Frequency Resonant Cavities
(MDPI, 2014-06)
In many micro- and nano-scale technological applications high sensitivity displacement sensors are needed, especially in ultraprecision metrology and manufacturing. In this work a new way of sensing displacement based on ...
A method for the sag-tension calculation in electrical overhead lines
(Praise Worthy Prize, 2011-06)
The sag and tension values of overhead conductors are influenced by the creep developed during the line lifetime. This paper presents a method for the sag-tension calculation of overhead conductors that is characterised ...
Flexible Strain-Tension Calculation Method for Gap-type Overhead Conductors
(IEEE, 2009-07)
Commercially available sag-tension programs give good results for most practical applications. However, they have some limitations concerning gap-type conductors. A separate aluminum and core creep calculation is needed ...
