This thesis investigates the impact of different factors on public displays that use touch and mid-air gestures. We present a novel application for public displays: MirrorTouch — a game combining touch interaction with mid-air gesturing through depth sense. We studied the impact of these factors through a series field studies. We show that clear affordances are important to communicate both mod...

Article history: Received 21 October 2011 Received in revised form 19 June 2012 Accepted 21 June 2012 Available online 21 July 2012 This article analyzes the adoption of B2B-e-business technology in German automotive supplier companies during the internet hype period, i.e. in the very early stage of technology diffusion. While from the outset e-business was assumed to be used by companies in or...

Conjugated polymers based on the donor of an asymmetric 5H-dithieno[3,2-b:2′,3′-d]pyran (DTPa) and the acceptors of benzo[d][1,2,3]triazole (BTA) or di-fluorinated benzo[d][1,2,3] triazole (ffBTA) with thiophene as π-bridge were designed and synthesized. Two asymmetric-buildingblock-containing polymers (ABC-polymers) possess a strong and broad absorption in the range of 300–750 nm and medium op...

The spectroscopy and photodissociation dynamics of the vinoxy ~CH2CHO! radical B̃( A9) ←X̃(A9) transition have been investigated by fast beam photofragment translational spectroscopy. We show conclusively that excitation to the B̃ state is followed by predissociation, even for the origin transition. Two photodissociation channels are observed: ~1! CH31CO, and ~2! H1CH2CO, with a branching ratio of...

This paper investigates the effectiveness of the Memoryless Simplification approach described by Lindstrom and Turk [14]. Like many polygon simplification methods, this approach reduces the number of triangles in a model by performing a sequence of edge collapses. It differs from most recent methods, however, in that it does not retain a history of the geometry of the original model during simp...

Deep CNNs are known to exhibit the following peculiarity: on the one hand they generalize extremely well to a test set, while on the other hand they are extremely sensitive to so-called adversarial perturbations. The extreme sensitivity of high performance CNNs to adversarial examples casts serious doubt that these networks are learning high level abstractions in the dataset. We are concerned w...

Boars (entire male pigs) consume less feed than barrows (castrated male pigs) under practical ad libitum feeding conditions, but the knowledge about possible reasons is only limited. Since the lysine and energy contents of the diet are known to be important determinants of voluntary feed intake, it was of interest if sex specific responses to selected dietary lysine-toenergy ratios could explai...

Watson, the winner of the Jeopardy! challenge, is a state-of-the-art open-domain Question Answering system that tackles the fundamental issue of answer typing by using a novel type coercion (TyCor) framework, where candidate answers are initially produced without considering type information, and subsequent stages check whether the candidate can be coerced into the expected answer type. In this...
