An EEMD Aided Comparison of Time Histories and Its Application in Vehicle Safety
2017
In the context of signal processing, the comparison of time histories is required for different purposes, especially for the model validation of vehicle safety. Most of the existing metrics focus on the mathematical value only. Therefore, they suffer the measuring errors, disturbance, and uncertainties and can hardly achieve a stable result with a clear physical interpretation. This paper proposes a novel scheme of time histories comparison to be used in vehicle safety analysis. More specifically, each signal for comparison is decomposed into a trend signal and several intrinsic mode functions (IMFs) by ensemble empirical mode decomposition. The trend signals reflect the general variation a…
Taideteollisuuden hyvät, pahat ja ristiriitaiset : kriisikeskustelua muotoilusta 1970-luvun Suomessa
2011
Työssä on perehdytty taideteollisuuden kriisikeskusteluun, jota käytiin 1970-luvun loppupuolella Helsingin Sanomien kulttuurisivuilla sekä alan ammatillisissa julkaisuissa. Debattiin osallistui sisustusarkkitehtejä, teollisia muotoilijoita, taiteilijoita ja taidehistorioitsijoita. Työn keskeisin ongelma on, mitä eliitti tarkoitti taideteollisuuden kriisillä 1970-luvulla. Mikä oli keskustelua käyneiden kirjoittajien mielestä ongelman ydin? Miten se ilmeni? Kirjoittajilta kysytään, mistä ongelmat johtuivat ja millaisia ratkaisuja he tarjosivat. Lisäksi kysytään, miten määriteltiin taideteollisuuden yhteiskunnallinen tehtävä. Työssä pyritään tuomaan esille nekin ongelmat, jotka ovat kätkeytyne…

Meu caro amigo Lucio, Ciao
2012
Quando eu era criança, imaginava que tudo na Itália tinha o cheiro e a forma das músicas de Lucio Dalla. Do primeiro Lucio Dalla. Hoje, Dalla representa um pouco a imagem triste da decadência da parte mais bela do país onde escolhi viver. Um pouco como aquelas virgens deprimidas e infelizes que a religião católica impõe aos seus fiéis. Na gênese, Lucio Dalla era de esquerda, genial, "malgré lui". Em 1976, pouco antes que eu nascesse, seu amigo Chico Buarque, que o tinha conhecido quando exilado na Itália, lhe escreveu uma carta sobre um Brasil em plena ditadura. Uma das músicas mais visionarias da historia da MPB: "Meu Caro Amigo".
Inter and intra-guild interactions in egg parasitoid species of the soybean stink bug complex
2002
Abstract – The objective of this research was to evaluate the parasitism behavior of Telenomus podisiAshmead, Trissolcus basalis (Wollaston) e Trissolcus urichi Crawford (Hymenoptera: Scelionidae) oneggs of Nezara viridula L., Euschistus heros F., Piezodorus guildinii Westwood and Acrosternumaseadum Rolston (Heteroptera: Pentatomidae), in no choice and multiple choice experiments. For allparasitoid species, the results demonstrated the existence of a main host species that maximizes thereproductive success. The competitive interactions among the parasitoid species were investigated inexperiments of sequential and simultaneous release of different combinations of parasitoid pairs on thehosts…

The interactive effects of various nitrogen fertiliser formulations applied to urine patches on nitrous oxide emissions in grassland
2017
AbstractPasture-based livestock agriculture is a major source of greenhouse gas (GHG) nitrous oxide (N2O). Although a body of research is available on the effect of urine patch N or fertiliser N on N2O emissions, limited data is available on the effect of fertiliser N applied to patches of urinary N, which can cover up to a fifth of the yearly grazed area. This study investigated whether the sum of N2O emissions from urine and a range of N fertilisers, calcium ammonium nitrate (CAN) or urea ± urease inhibitor ± nitrification inhibitor, applied alone (disaggregated and re-aggregated) approximated the N2O emission of urine and fertiliser N applied together (aggregated). Application of fertili…
Computational Structures and SAPT Interaction Energies of HXeSH···H2Y (Y=O or S) Complexes
2018
Ab initio calculations of the structures, vibrational spectra and supermolecular and symmetry-adapted perturbation theory (SAPT) interaction energies of the HXeOH and HXeSH complexes with H2O and H2S molecules are presented. Two minima already reported in the literature were reproduced and ten new ones were found together with some transition states. All complexes show blue shift in Xe&ndash
Non-linear analysis of plane steel prestressed truss in fire
2002
The concept of analysis of 2-D static loaded prestressed steel trusses till failure during fire using a modified method of forces is presented. Failure of steel trusses in fire is based on the criterion of stresses. Behaviour of steel is described by non-linear constitutive model (based on hypo-elastic Ramberg-Osgood formula and Dorn creep theory) and Plem proposition (for string). Both models are approximated in calculations by hyperbolic Norton-Bailey rule. Fire simulates thermal force as an action of high temperature that increases linearly up to some level. The complete formulation of this method is illustrated by the algorithm of model parameters identification. Analysis of results for…
Modelling of Emissions from Large Biogas Plants
2015
Głównym celem wskazanym w „Wytycznych dla rozwoju biogazowni rolniczych w Polsce w latach 2010-2020” jest budowa biogazowni rolniczych przetwarzających zasoby biomasy w odpowiednich dla gminy warunkach. W Czechach produkuje się około 6,5% energii ze źródeł odnawialnych. Biogazownie, w przeciwieństwie do elektrowni słonecznych i wiatrowych, pracują stabilnie przez cały rok. Biomasa powinna być kluczowym źródłem realizacji zobowiązań czeskich wobec UE, w ramach których przyjęto produkcję 13% energii ze źródeł odnawialnych w 2020 roku. Dotychczasowe doświadczenia z działającymi 317 biogazowniami rolniczymi wykazały, że istnieją poważne problemy z właściwym ulokowaniem nowo zaprojektowanych bio…
