On the impossibility of a fixed point proof of the fundamental theorem of algebra. Seminar on mathematical analysis

The author shows that the proofs of \n B. H. Arnold\en [Amer. Math. Monthly 56 (1949), 465--466; MR0031725 (11,195h)] and \n I. Niven\en [ibid. 57 (1950), 246--248; MR0035738 (12,4c)] of the fundamental theorem of algebra, based on the Brouwer fixed point theorem, are incomplete. Both Arnold and Niven recognized that the proofs are invalid, and they remarked that no easy remedy seems to save their

Résumé : Le français écrit est caractérisé par de nombreuses marques morphologiques qui ne se prononcent pas. Cet article pose la question de savoir quand et sur quels constituants de la phrase les apprenants de français L2 font l’accord en nombre, souvent silencieux, à l’écrit. Dans une optique de développement qui s’inspire des travaux de Bartning et Schlyter (2004) dans le domaine du français p

Controlled by the standard? - The effects of quality assurance on professions

This paper will focus the effects of quality assurance in the Swedish health care sector and the auditing business. Our aim is to analyse, the two professions, doctors' and auditors', role in the development. The main issue is in what way the two professions have intervened in the development, introduction and implementation of the quality assurance programmes in the two fields amd whether or not

A Sequential Lot Sizing Heuristic with Optimal Average Performance

Diffusion, Influence and Best-Response Dynamics in Networks : An Action Model Approach

Threshold models and their dynamics may be used to model the spread of ‘behaviors’ in social networks. Regarding such from a modal logical perspective, it is shown how standard update mechanisms may be emulated using action models – graphs encoding agents’ decision rules. A small class of action models capturing the possible sets of decision rules suitable for threshold models is identified, and s

Time extraction from real-time generated football reports

This paper describes a system to extract events and time information from football match reports generated through minute-by-minute reporting. We describe a method that uses regular expressions to find the events and divides them into different types to determine in which order they occurred. In addition, our system detects time expressions and we present a way to structure the collected data usin

Vi riskerar att drabbas av övervakningshysteri.

Det var mycket vi inte trodde oss veta innan en amerikansk dataanalytiker tog sin hårddisk och flydde undan världens kanske mäktigaste underrättelsetjänst. Man skulle också kunna lägga till ett ”ännu”. För det kan förstås ändras med tiden. Ingen lyssnar på vad vi säger till varandra. Ingen läser vad vi skriver till varandra. Ännu. Puh.
