This essay reflects on the ”-ology of technology”, pace Brian Arthur (2009), as conveyed in theformal (i.e. mathematical) treatment of technology and innovation in economic theory. In thedecades from the 1970s economists of the evolutionary strand have levied criticism on the way inwhich technology is handled in mainstream economics. Some of this criticism has concerned theassumptions made in part

This thesis describes experiments involving laser-plasma-based acceleration of electrons and protons, using the techniques of laser wakefield acceleration (LWFA) and target normal sheath acceleration (TNSA). By using extremely high accelerating field strengths, up to the order of TV m-1, it is possible to reach high kinetic particle energies over very short distances.The multi-terawatt laser syste

Traditionally, the law has been considered as devoid of emotions, however recent research has begun to analyze the courtroom as an emotional scene. The emotion norms of the courtroom are thus interesting to explore and, as the courtroom work and emotions of de- fense lawyers have received little sociological attention, this will be the focus of this paper. The aim here is to show the emotions that

High temperatures have a direct impact on body functions. Heat waves increase mortality risks due to myocardial infarction, stroke, and pulmonary disease. Cold temperatures also increase mortality, but with a longer latency. A recent study found only a small difference between the minimal mortality temperature (MMT) and the temperatures at which mortality rose steeply, although the majority of dea

The field of high dynamic range imaging addresses the problem of capturing and displaying the large range of luminance levels found in the world, using devices with limited dynamic range. In this paper we present a novel tone mapping algorithm that is based on K-means clustering. Using dynamic programming we are able to not only solve the clustering problem efficiently, but also find the global op

Mites can sensitize and induce atopic disease in predisposed individuals and are an important deteriorating factor in patients with allergic rhinitis, asthma, and atopic dermatitis. Although Pyroglyphidae mites have been extensively studied, very scarce reports are available on Cheyletidae spp. especially regarding human respiratory pathology. The main objective of the present study is to investig

BACKGROUND: Life satisfaction (LS) is an overall goal in the long-term management and rehabilitation of persons with Parkinson's disease (PD). However, very little is known about LS in persons with PD and no study has examined factors associated with their LS. OBJECTIVE: To describe LS in persons with mild to moderate PD and to evaluate the association with gender, age, years since diagnosis, and

In this paper we present a system for performing low rank matrix factorization. Low-rank matrix factorization is an essential problem in many areas including computer vision, with applications in e.g. affine structure-from-motion, photometric stereo, and non-rigid structure from motion. We specifically target structured data patterns, with outliers and large amounts of missing data. Using recently
