The Old Guard Under a New Order: K. O. Friedrichs Meets Felix Klein
2018
Constance Reid’s recent tribute to K. O. Friedrichs (Reid 1983) undoubtedly brought back fond memories to those who knew the man and his many achievements (see also Reid 1986). It was a great pleasure for me to interview Friedrichs in January 1982, only about a year before his death. He was already in very delicate health. His wife Nellie (see Biegel 2012) was kind enough to arrange the interview, but warned me beforehand that her husband tired rather easily and was somewhat hard of hearing. Nevertheless, he was extremely forthcoming in discussing his early career with me, and quick to dismiss some of my faulty misconceptions regarding Gottingen mathematics in the 1920s, which was the main …
La giurisprudenza del Collegio di Garanzia dello Sport nel suo quarto anno di attività
2018
This essay analyzes the decisions of Sport Guarantee Committee issued in the year 2018. It follows the previous essay dedicated to the jurisprudence of Sport Guarantee Committee during the past three years of activity, published in this same journal, with the dual aim of updating with respect to the issues already dealt with therein and of enlargement with regard to new issues. As well as the previous, the present essay, for the function prformed by the Author within the Sport Guarantee Committee, carries a reasoned analysis, but with a merely descriptive cut, of the main jurisprudential approaches expressed in the decisions of the Guarantee Committe, with the aim to extrapolate the rules a…
Responses of Young Peach Trees to Root Confinement
1994
Rooted cuttings of Nemaguard peach [Prunus persica (L.) Batsch.] were grown in 0.18-, 0.36-, 0.90-, and 2.40-liter containers for 16 weeks to study the influence of root confinement on growth, gas exchange, water uptake, and leaf carbohydrate and nutrient content. An automatic nutrient-solution dispensing system was used to ensure uniform fertility among treatments and to prevent drought stress. Leaf area and stem length were reduced by root confinement 6 to 7 weeks after transplanting, and differences among treatments increased throughout the experiment. Final tree dry weights were reduced by 51% over a 13-fold reduction in rooting volume, but dry weight partitioning was largely unaffected…
Evaluation of Insurance Products with Guarantee in Incomplete Markets
2008
Abstract Life insurance products are usually equipped with minimum guarantee and bonus provision options. The pricing of such claims is of vital importance for the insurance industry. Risk management, strategic asset allocation, and product design depend on the correct evaluation of the written options. Also regulators are interested in such issues since they have to be aware of the possible scenarios that the overall industry will face. Pricing techniques based on the Black & Scholes paradigm are often used, however, the hypotheses underneath this model are rarely met. To overcome Black & Scholes limitations, we develop a stochastic programming model to determine the fair price of the mini…
Designing and pricing guarantee options in defined contribution pension plans
2015
Abstract The shift from defined benefit (DB) to defined contribution (DC) is pervasive among pension funds, due to demographic changes and macroeconomic pressures. In DB all risks are borne by the provider, while in plain vanilla DC all risks are borne by the beneficiary. However, for DC to provide income security some kind of guarantee is required. A minimum guarantee clause can be modeled as a put option written on some underlying reference portfolio and we develop a discrete model that selects the reference portfolio to minimize the cost of a guarantee. While the relation DB–DC is typically viewed as a binary one, the model shows how to price a wide range of guarantees creating a continu…
Road restraint systems monitoring with stereoscopic dip-technique
2015
Road restraint systems (RRS) are used to protect vehicle occupants from dangerous roadside elements such as rigid obstacles, slopes, utility poles, etc. The crashes on a road restraint system damage its structure and, therefore, the functional behavioral; for this reason is required monitoring the RRS into their operational conditions. The research addresses the problem of the measurement of safety barrier (SB) deformations by means digital image processing technique (DIP). This technique is founded on the analysis of high resolution photos/videos, obtained by means of 3D camera installed into a data vehicle. The DIP technique has been used for evaluating the longitudinal safety barriers de…
Storiografia e architettura: il caso Gurlitt/Valguarnera
2012
En 1916, Cornelius Gurlitt - historien allemand d’architecture qui a beaucoup contribué à la réévaluation de l’art baroque - travaillait à la seconde édition de son «Histoire du Baroque en Italie». L’equipe de recherche qu’il avait envoyé en Sicile, avait effectué un relevé complet de la villa Valguarnera à Bagheria, l’un des ensembles monumentaux parmi les plus importants de l’Italie méridionale. Mais cette seconde édition de son œuvre ne fut jamais publiée et ce précieux relevé semble avoir disparu
Bivariate analysis of taekwondo actions: The effectiveness of techniques and tactics in an Olympic taekwondo championship.
2020
This paper describes the effectiveness of technical-tactical actions performed during a tournament. A total of 14,145 actions of the 2012 London Olympic Games were analysed. Differences emerged in the use of tactics, techniques, zones, legs and guard to score. Regarding tactics, anticipatory counterattacks were the most effective for scoring one and three points. Circular techniques were the most effective for scoring one point, linear to score three points, and spin techniques to score two and four points. Actions to the chest results in a score of one to two points and actions to the head in a score of three to four points. The rear leg was more effective in scoring one, two and four poin…
