Alder pollen in Finland ripens after a short exposure to warm days in early spring, showing biennial variation in the onset of pollen ripening
2017
We developed a temperature sum model to predict the daily pollen release of alder, based on pollen data collected with pollen traps at seven locations in Finland over the years 2000–2014. We estimated the model parameters by minimizing the sum of squared errors (SSE) of the model, with weights that put more weight on binary recognition of daily presence or absence of pollen. The model results suggest that alder pollen ripens after a couple of warm days in February, while the whole pollen release period typically takes up to 4 weeks. We tested the model residuals against air humidity, precipitation and wind speed, but adding these meteorological features did not improve the model prediction …
Probabilistic Evaluation of the Adaptation Time for Structures under Seismic Loads
2016
Abstract In this paper, a probabilistic approach for the evaluation of the adaptation time for elastic perfectly plastic frames is proposed. The considered load history acting on the structure is defined as a suitable combination of quasi-statical loads and seismic actions. The proposed approach utilizes the Monte Carlo method in order to generate a suitable large number of seismic acceleration histories and for each one the related load combination is defined. Furthermore, for each load combination the related adaptation time is determined, if any, as the optimal one for which the structure is able to shakedown under the unamplified applied actions. A known generalized Ceradini's theorem i…
Reinventare spazi nella dinamica dell’abitare. Un racconto su Giancarlo De Carlo
2019
Fra le riflessioni su modalità ed esperienze costruite, non tralasciano le vicende biografiche, sembra quasi apparire Andrea De Carlo che nel ‘girare’ il cannocchiale avverte: ‘Il primo scopo che ci si dovrebbe porre è dunque di ricostruire la consapevolezza dell’unità del territorio; dimostrando che ogni territorio ha un ‘disegno’, è intessuto di innumerevoli stratificazioni, percepibili una per una o nelle loro varie sovrapposizioni, dal dettaglio all’insieme e viceversa, secondo cosa e come si mette a fuoco nell’osservazione’. Il saggio rivela alcune ricognizioni dentro le architetture di De Carlo e le sottese strategie di progetto. Queste rappresentano in qualche modo una questione rile…
The efficiency of the incentives for the public buildings’ energy retrofit. The case of the Italian Regions of the “Objective Convergence”
2017
Gli obiettivi di riduzione del consumo energetico e delle emissioni di gas serra, enunciati in molte Direttive europee, hanno posto in risalto la necessità di promuovere interventi di miglioramento dell’efficienza energetica del patrimonio edilizio esistente. Le amministrazioni locali, in particolare, dovrebbero assumersi la responsabilità di diffondere la cultura ambientale anche effettuando interventi di retrofit negli edifici pubblici di loro proprietà, sulla base di diagnosi energetiche degli edifici, di proposte progettuali e di verifiche del raggiungimento della convenienza finanziaria, che può essere agevolata dall’erogazione di incentivi. L’Unione Province d’Italia (UPI) nel 2013, n…
Identifying territories using presence-only citizen science data : An application to the Finnish wolf population
2022
Citizens, community groups and local institutions participate in voluntary biological monitoring of population status and trends by providing species data e.g. for regulations and conservation. Sophisticated statistical methods are required to unlock the potential of such data in the assessment of wildlife populations. We develop a statistical modelling framework for identifying territories based on presence-only citizen science data. The framework can be used to jointly estimate the number of active animal territories and their locations in time. Our approach is based on a data generating model which consists of a dynamic submodel for the appearance/removal of territories and an observatio…
Charged jet cross sections and properties in proton-proton collisions at $\sqrt{s}=7$ TeV
2015
The differential charged jet cross sections, jet fragmentation distributions, and jet shapes are measured in minimum bias proton-proton collisions at centre-of-mass energy $\sqrt{s}=7$ TeV using the ALICE detector at the LHC. Jets are reconstructed from charged particle momenta in the mid-rapidity region using the sequential recombination $k_{\rm T}$ and anti-$k_{\rm T}$ as well as the SISCone jet finding algorithms with several resolution parameters in the range $R=0.2$ to $0.6$. Differential jet production cross sections measured with the three jet finders are in agreement in the transverse momentum ($p_{\rm T}$) interval $20<p_{\rm T}^{\rm jet,ch}<100$ GeV/$c$. They are also consistent w…
A comprehensive guide to the physics and usage of PYTHIA 8.3
2022
This manual describes the PYTHIA 8.3 event generator, the most recent version of an evolving physics tool used to answer fundamental questions in particle physics. The program is most often used to generate high-energy-physics collision "events", i.e. sets of particles produced in association with the collision of two incoming high-energy particles, but has several uses beyond that. The guiding philosophy is to produce and reproduce properties of experimentally obtained collisions as accurately as possible. The program includes a wide ranges of reactions within and beyond the Standard Model, and extending to heavy ion physics. Emphasis is put on phenomena where strong interactions play a ma…
Mannerheim ja muuttuvat tulkinnat : mediatisoitunut kansalaisuskonto 2000-2010-lukujen kulttuurikiistoissa
2019
Marsalkka Mannerheim esiintyi usein uutisotsikoissa vuosina 2001–2014. Keskustelua synnytti aika ajoin Renny Harlinin ja Markus Selinin Mannerheim-suurelokuvahanke. Lööppeihin nousi myös Katariina Lillqvistin nukkeanimaatio Uralin perhonen, jossa Mannerheimia muistuttava hahmo seikkailee Keski-Aasiassa ja sisällissodan Suomessa, ottaa kirgiisinuorukaisen rakastajakseen ja teloittaa punaisten pahvikuvia. Kesällä 2012 tuli julki tieto Ylen Mannerheim-elokuvaprojektista, jossa Mannerheimia esittää tummaihoinen kenialainen. Kirjassa tarkastellaan näiden kolmen Mannerheim-aiheisen teoksen ympärillä käytyjä mediakeskusteluja, joissa produktiot sijoitetaan kulttuurin kentille eri tavoin. Erilaiste…

SNP and SML estimation of univariate and bivariate binary–choice models
2008
We discuss the semi-nonparametric approach of Gallant and Nychka (1987, Econometrica 55: 363–390), the semiparametric maximum likelihood approach of Klein and Spady (1993, Econometrica 61: 387–421), and a set of new Stata commands for semiparametric estimation of three binary-choice models. The first is a univariate model, while the second and the third are bivariate models without and with sample selection, respectively. The proposed estimators are root-n consistent and asymptotically normal for the model parameters of interest under weak assumptions on the distribution of the underlying error terms. Our Monte Carlo simulations suggest that the efficiency losses of the semi-nonparametric a…
