Modeling and Backstepping Control of the Electronic Throttle System
2013
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/871674 Open access Electronic throttle is widely used in modern automotive engines. An electronic throttle system regulates the throttle plate angle by using a DC servo motor to adjust the inlet airflow rate of an internal combustion engine. Its application leads to improvements in vehicle drivability, fuel economy, and emissions. In this paper, by taking into account the dynamical behavior of the electronic throttle, the mechanism model is first built, and then the mechanism model is transformed into the state-space model. Based on the s…
A Sub-Supersolution Approach for Robin Boundary Value Problems with Full Gradient Dependence
2020
The paper investigates a nonlinear elliptic problem with a Robin boundary condition, which exhibits a convection term with full dependence on the solution and its gradient. A sub- supersolution approach is developed for this type of problems. The main result establishes the existence of a solution enclosed in the ordered interval formed by a sub-supersolution. The result is applied to find positive solutions.
Location of solutions for quasi-linear elliptic equations with general gradient dependence
2017
Existence and location of solutions to a Dirichlet problem driven by $(p,q)$-Laplacian and containing a (convection) term fully depending on the solution and its gradient are established through the method of subsolution-supersolution. Here we substantially improve the growth condition used in preceding works. The abstract theorem is applied to get a new result for existence of positive solutions with a priori estimates.

The War Heroine in the Finnish Organization : Lotta Svärd
2017
This paper focuses on a Finnish women’s paramilitary organization called ‘Lotta Svärd’ in a wartime context, from 1939 to 1944. During the Second World War, thousands of members of the organization served as volunteers with the Finnish Army. The primary data for this study consist of the organization’s magazine, Lotta Svärd, as well as archival documents stored in the Finnish War Document Archives. This study seeks to explore what kind of war heroine was constructed in Lotta Svärd. We found four representations of the heroine: Mother, Soldier, Body and Holy Sacrifice. While war histories are mainly written by men and for men, this study is intended to contribute to research by presenting wo…
Il sistema di copertura del Teatro Politeama di Palermo
2012
In the project of the Politeama’s Theater in Palermo, the Architect Almeyda summarizes, in an expressive and model balance, the technological component and geometrical/spatial shape, providing optimal solutions to a structural and functional problems. Thanks to its typological approach, thanks to its technological aspects and, specifically, thanks to its size and its style, the work offers us some interesting reflections about the technical choices carried out for the construction. The Author, basing on some original Almeyda’s drawings, deepens the geometric and compositional system of the roof. The daring and complex construction carried out in iron and glass, modern and progressive in for…
Una città reiventata
2007
A partire dall’esame del documento che elenca le ragioni dell’iscrizione di Ragusa nella World Heritage List, il saggio propone un inquadramento critico, previa contestualizzazione storica, delle vicende ricostruttive avviate a seguito del terremoto del 1693 nella città di Ragusa. Nel quadro comitale, l’opzione dello sdoppiamento si rivela “singolare” e offre lo spunto per indagare sincronicamente due diverse problematiche: nel caso della città superiore, quella afferente la fondazione ideale di uno spazio urbano, condotta attraverso l’adozione di un piano urbanistico che rendeva immediatamente leggibile l’innesto delle gerarchie sociali; nel caso dell’antico sito, in assenza di un piano no…

"Voi sen ajan terveyssisaria!" : lappilaisen terveyssisaren muisteltu työ 1930-luvun lopulta 1960-luvun alkuun
2016
Tässä tutkimuksessa tarkastelen terveyssisar Tytti Huotarin tekemää työtä pienessä lappilaisessa Pelkosenniemen kunnassa 1930-luvun lopulta 1960-luvun alkuun saakka. Huotari on isoäitini ja hän kirjoitti vuosia työuransa jälkeen muistelmat, joissa hän paneutuu kuvaamaan tekemäänsä työtä ja siihen vaikuttaneita olosuhteita. Nämä muistelmat muodostavat toisen puolen tutkimuksen lähdeaineistosta. Lisäksi täydennän ammatinharjoittajan itsensä muistoja kyläläisille tekemilläni haastatteluilla, joissa he kertovat omia kokemuksiaan terveyssisaren työstä. Tutkin, miten Huotari kertoo työstään, millaista kuvaa rakentaa itsestään terveydenhuollon ammattilaisena ja myös sitä, mitä hän jättää kertomatt…
