Existence and comparison results for a singular semilinear elliptic equation with a lower order term
2014
This paper deals with the homogeneous Dirichlet problem for a singular semilinear elliptic equation with a first order term. When the datum is bounded we prove an existence result and we show that any solution can be compared with the solution to a suitable symmetrized problem.
Jalkalihasten sähköinen aktiivisuus ja reaktiovoimat joukkuevoimistelun harppa- ja rengashypyissä
2010
Takala, Henni 2010. Jalkalihasten sähköinen aktiivisuus ja reaktiovoimat joukkuevoimistelun harppa- ja rengashypyissä. Liikuntabiologian laitos, Jyväskylän yliopisto, 48 sivua. Joukkuevoimistelu on yksi voimistelulajeista, joka on kehittynyt suomalaisesta naisvoimistelusta. Joukkuevoimistelu perustuu tyyliteltyyn ja luonnolliseen kokonaisliikuntaan, jossa kaikki liikkeet sitoutuvat toisiinsa sulavasti ja jatkuvasti luoden kuvan, että edellinen liike synnyttää aina seuraavan. Kilpailuohjelman tulee sisältää monipuolisesti hyppyjä, tasapainoja ja vartalonliikkeitä. Tämän tutkimuksen tavoitteena oli selvittää lihasten aktivaatiomallit ja alustaan tuotetut reaktiovoimat joukkuevoimistelun harpp…
Desarrollo de productos avanzados para la misión SEOSAT/Ingenio
2016
SEOSAT/Ingenio es la futura misión española de observación de la Tierra en el óptico en alta resolución espacial. Mientras que los productos de imagen a Nivel 1, radiancias geo-referenciadas a nivel de sensor, se encuentran en una fase avanzada de desarrollo existiendo para ello un contrato industrial, los productos de Nivel 2 deben ser desarrollados por los propios usuarios. Este hecho limita el uso de las imágenes a la comunidad científica, restringiendo sus posibles aplicaciones fuera de ésta. Así pues, bajo el marco de un proyecto coordinado y motivados por ofrecer productos de Ingenio/SEOSAT de Nivel 2 a disposición de cualquier usuario, se origina y desarrolla este trabajo. En este ar…
Diversity of meiofauna in the lacustrine profundal zone: Bathymetric differences and influence of environmental factors
1993
The diversity and species richness of total meiofauna, Harpacticoida and Oligochaeta in relation to depth and other environmental variables were studied at nine stations and in two profundal depth zones in Lake Paijanne which includes both oligotrophic and eutrophicated or organically loaded areas.
Portfolio performance evaluation with generalized Sharpe ratios: Beyond the mean and variance
2009
The main purpose of this paper is to present a theoretically sound portfolio performance measure that takes into account higher moments of the distribution of returns. First, we perform a study of the investor's preferences to higher moments of distribution within expected utility theory and discuss the performance measurement. To illustrate the investor's preferences to higher moments and the computation of a performance measure, we provide an approximation analysis of the optimal capital allocation problem and derive a formula for the Sharpe ratio adjusted for skewness of distribution. This performance measure justifies the notion of the Generalized Sharpe Ratio (GSR) introduced by Hodges…
Mooring Line Components With Semi-Brittle Behavior: Verification of Fitness for Purpose
2011
Low impact energy for Charpy V Notch (CVN) specimens and associated low Crack Tip Opening Displacement (CTOD) values have occurred on several occasions in high strength steel offshore mooring components. In the present work an Engineering Critical Assessment (ECA) for shackles has been carried out to demonstrate fitness for purpose. Typical values for CVN and CTOD are 17 Joules and 0.01 mm respectively at design temperature. The purpose of the present work is to demonstrate that even in the case where normal quality requirements are not met, the shackles may still have enough structural integrity and fatigue durability to withstand the load spectrum in the field during the planned target se…
New Theoretical Solution of the Stage-Discharge Relationship for Sharp-Crested and Broad Weirs
2012
In this paper, the outflow process of a sharp-crested and broad weir is studied using the dimensional analysis and the incomplete self-similarity theory. The new stage discharge is theoretically deduced and its testing is carried out using measurements both available in literature and obtained by laboratory runs carried out in this investigation.
New theoretical solution of the outflow process with a weir with complex shape
2016
AbstractIn this paper, the outflow process of a weir with an irregular shape is studied using dimensional analysis and the incomplete self-similarity theory. The new unique stage–discharge relationship, which is deduced theoretically, represents a novel and comprehensive equation to describe the weir outflow process for a full range of flow and different geometric variables of weirs, including finite-crested weirs, broad-crested weirs with positive or negative crest slope, broad-crested weirs with an upstream, downstream, or both upstream and downstream crest ramps, and, triangular weirs with an upstream or downstream ramp. Finally the proposed stage–discharge relationship is calibrated usi…
The harp: a vehicle crash test apparatus for full-scale crash test experiments
2012
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-012-3960-3 The current paper describes an apparatus for full-scale vehicle crash test experimentation. This apparatus is referred to as the harp. In brief, the harp may either accelerate a trolley which is impacted into a test vehicle or the test vehicle itself may be accelerated and impacted into an object such as a barrier, a pole, or another vehicle. If a trolley is accelerated, it is equipped with load cells to record the axial crushing force. If a test vehicle is accelerated, it is equipped with a three-ax…
Volatility-Managing International Equity Risk Factors
2018
Recent research (see Moreira and Muir, 2017) suggests that volatility-managed portfolios take less risk when volatility is high produce large alphas, increase Sharpe ratios, and produce large utility gains for mean-variance investors. We extend this literature by investigating the profitability of volatility-managing the Fama and French (2017) local risk factors in international equity markets. Our general findings indicate that volatility-managing adds value for local risk factors in Europe and Asia, whereas in Japan we find no such evidence. Confirming earlier studies, we find that a risk-based story is unlikely to explain our results.
