Off-diagonal estimates for bi-parameter commutators
2022
Tutkimme kahden parametrin singulaari-integraalien kommutaattoreiden rajoit-tuneisuutta iteroitujen avaruuksien[b, T]:Lp1Lp2→Lq1Lq2välillä kunqi, pi∈(1,∞)ja erityisesti fraktionaalisessa tilanteessaqi6=pi. Yhteensä seitsemässä ta-pauksessa yhdeksästä saavutamme täyden karaterisoinnin rajoittuneisuudella symboliabkoskevillaoskillatorisilla testiehdoilla. We study the boundedness of commutators of bi-parameter singular integrals between mixed spaces [b,T]:Lp1Lp2→Lq1Lq2 in the off-diagonal situation qi,pi∈(1,∞) where we allow qi≠pi. Boundedness is fully characterized in terms of oscillatory testing conditions on the function b for a total seven out of the nine possible arrangements of the inte…
Operācijas laika ietekme uz apendektomijas rezultātu
2018
Kopsavilkums Nosaukums: Operācijas laika izvēles ietekme uz apendektomijas rezultātu Fons: Apendektomija ir viena no pasaulē visbiežāk veiktajām akūtajām ķirurģiskajām manipulācijām. Vēsturiski to veic nekavējoties un neatkarīgi no diennakts laika. Tomēr ir svarīgi jautāt, vai laika izvēle ietekmē klīnisko rezultātu. Mērķis: Pētījuma mērķis ir izvērtēt, vai apendektomiju ir iespējams aizkavēt vai arī tiešas ķirurģiskas iejaukšanās gadījumā rezultāts būs labāks. Materiāli un metodes: Šis ir retrospektīvs pētījums ar nejauši atlasītiem pacientiem ar apendektomiju, kas veikta Rīgas Austrumu klīniskajā universitātes slimnīcā 2015. un 2016. gadā. Vērtējuma parametri; vecums, dzimums, ķirurģiskai…

Linee guida per le comunita’ per minori. Uno strumento per la definizione di standard di funzionamento.
2012
Le comunità e le strutture residenziali si possono connotare come “setting terapeutici”, capaci di generare un clima di spessore affettivo, sviluppare nuove, sicure e funzionali possibilità di esperienze interpersonali, assicurare un regolare svolgimento del percorso di crescita e la creazione di uno spazio mentale dedicato all’elaborazione di un progetto per il minore (Giannone, 2005; Brunori, Raggi, 2007; Bastianoni, Taurino, 2009). Il network della Community of Communities lavora ad un processo sistematico di miglioramento della qualità delle Comunità terapeutiche per bambini e adolescenti attraverso la formulazione di standard grazie ai quali le equipe e gli utenti delle comunità posson…

AMBIENTE COSTRUITO E SOSTENIBILITÀ – Materiali riciclati e Design for Disassembly tra ricerca e buone pratiche
2020
In the context of environmental emergency of which the construction sector is one of the main causes – since it consumes 40% of the (embodied and operational) energy and produces about a third of the total waste – and due to the ambitious objectives set by the international community and by many countries to reduce the environmental impact of buildings during their whole life cycle, this paper wants to make a contribution to the understanding of the state of the art on cycle-based research activities, sustainable experiments and good practices that the building industry and the academy have implemented in recent years. In particular, it refers to cycle-based theoretical and experimental act…
Strictly convergent algorithm for an elliptic equation with nonlocal and nonlinear boundary conditions
2012
The paper describes a formally strictly convergent algorithm for solving a class of elliptic problems with nonlinear and nonlocal boundary conditions, which arise in modeling of the steady-state conductive-radiative heat transfer processes. The proposed algorithm has two levels of iterations, where inner iterations by means of the damped Newton method solve an appropriate elliptic problem with nonlinear, but local boundary conditions, and outer iterations deal with nonlocal terms in boundary conditions.
Reducing whole-body vibration exposure in backhoe loaders by education of operators
2012
Author's version of an article published in the journal: International Journal of Industrial Ergonomics. Also available from the publisher at: http://dx.doi.org/10.1016/j.ergon.2012.03.001 Whole-body vibration is a health hazard for operators of construction machinery. The level of whole-body vibration exposure on the operator is governed by three different factors; performance of the suspension system of the machine, planning of the work and the skills of the operator.In this research work it is investigated whether there is a potential in bringing down the level of whole-body vibration exposure by educating operators of backhoe loaders. This is carried out by an experimental setup. Six ex…
Estabilización de modelos económicos dinámicos con control óptimo en tiempo continuo
1990
En esta Tesis de Licenciatura se lleva a cabo el estudio de un problema determinado de optimización dinámica y sus aplicaciones en el campo de la Ciencia Económica. Un problema de optimización consiste, fundamentalmente, en la búsqueda de un extremo de una función o un funcional objetivo que proporcione un máximo o un mínimo para esa función. Cuando se habla de optimización dinámica hay que incorporar el factor tiempo al problema, en todas y cada una de las diferentes variables que intervienen, lo que afectará a los modelos matemáticos que se empleen para representar el comportamiento y las relaciones existentes entre dichas variables. También afecta al funcional objetivo a optimizar. Así, …
StateOS : A Memory-Efficient Hybrid Operating System for IoT Devices
2023
The increasing significance of operating systems (OSs) in the development of the internet of things (IoT) has emerged in the last decade. An event-driven OS is memory efficient and suitable for resource-constrained IoT devices and wireless sensors, although the program’s control flow, which is determined by events, is not always obvious. A multithreaded OS with sequential control flow is often considered clearer. However, this approach is memory-consuming. A hybrid OS seeks to combine the strengths of the event-driven approach with multithreaded approach. An event-driven cooperative threaded OS represents a hybrid approach that supports concurrency by explicitly yielding control to another …
