A simple opto-fluidic switch detecting liquid filling in polymer-based microfluidic systems

A novel detection scheme for detection of liquid levels and bubbles in microfluidic systems, using the principle of total internal reflection (TIR) is presented. A laser beam impinges on the side walls of a channel which are inclined at 45deg. In an unfilled channel of such a "V-groove", TIR deflects the beam by 90deg into a simple light detector. Upon the presence of liquid, the refractive index in the channel changes, thus eliminating deflection by TIR. The detection principle is robust, requiring no calibration, and tolerating alignment errors of the laser larger than the width and depth of the microfluidic channels. The machining of the V-groves can seamlessly be integrated into common polymer microfabrication schemes such as injection molding

Translator Attitudes towards Translator-Computer Interaction – Findings from a Workplace Study

Today technology is part and parcel of professional translation, and translation has therefore been characterised as Translator-Computer Interaction (TCI) (O’Brien 2012). Translation is increasingly carried out using Translation Memory (TM) systems which incorporate machine translation (MT), referred to as MT-assisted TM translation, and in this type of tool, translators switch between editing TM matches and post-editing MT matches. It is generally assumed that translators’ attitudes towards technology impact on this interaction with the technology. Drawing on Eagly/Chaiken’s (1995) definition of attitudes as evaluations of entities with favour or disfavour and on qualitative data from a workplace study of TCI, conducted as part of a PhD dissertation (Bundgaard 2017) and partly reported on in Bundgaard et al. (2016), this paper explores translator attitudes towards TCI in the form of MT-assisted TM translation. In doing so, the paper has a particular focus on the disfavour towards TCI expressed by translators. Moreover, inspired by Olohan (2011), who applies Pickering’s “mangle of practice” theory and analyses resistance and accommodation in TCI, the paper focuses on how translators accommodate resistances offered by the tool. The study shows that the translators express disfavour towards MT in many respects, but also acknowledge positive aspects of the technology and expect MT to play a significant role in their future working lives. The translators do not make many positive or negative comments about TM which might indicate that TM is a completely integrated part of their processes. The translators seem to have a flexible and pragmatic attitude towards TCI, adapting to the tool’s imperfections and accommodating its resistances

Fra Lygten til Lorteøen: Forslag til letbane fra Nørrebro til Sundbyvester Plads

Artiklen baserer sig på specialeopgaven på uddannelsen til landskabsarkitekt. Under titlen ”Fra Lygten til Lorteøen” omhandler specialet, der blev afsluttet i september 2014, et forslag til en letbanelinje fra Nørrebro st. over Nørreport og København H til Amager. Forslaget tager udgangspunkt i de problemstillinger, som den nuværende busdrift skaber i korridoren i dag. Problemer som ikke bliver løst med en metrocityring. I artiklen argumenteres for, at det er muligt, under hensyntagen til øvrige trafikformer og bymiljø, at etablere en letbane som en forlængelse af en eventuel letbane på Frederikssundsvej, og at valget mellem letbane og metro ikke et enten eller, men at systemerne har hver deres styrker, og derfor kan supplere hinanden. Med letbanen vil de trafikale vilkår for cyklister og fodgængere blive forbedret, samtidig med at fremkommeligheden for biltrafikken prioriteres. Sidst men ikke mindst inddrages konkrete eksempler på, hvordan anlægget af letbanen bidrager til at skabe en række nye og forbedrede byrum langs strækningen
