Suomi ja viro oppijan mielessä : näkökulmia taivutusmuotojen prosessointiin
2006
Kielenoppijan äidinkielen eli lähdekielen (L1) ja opittavan kielen eli kohdekielen (L2) rakenteita ja sanastoa vertaillaan usein toisiinsa, koska havaittujen erojen ja yhtäläisyyksien oletetaan olevan jossakin suhteessa kielenoppimisen kulkuun ja oppijoiden kielellisiin tuotoksiin. Oletus perustuu käytännön kokemuksiin, mutta enenevästi myös tutkimustietoon (ks. erityisesti Kaivapalu 2005). Lähde- ja kohdekielen suhteen olemuksen tutkimuksellinen määritteleminen on kuitenkin haastavampi ja mutkikkaampi tehtävä kuin pelkkä kielten ja oppijoiden puheen ja kirjoituksen vertailu. peerReviewed
High-Reynolds-number turbulent cavity flow using the lattice Boltzmann method
2018
We present a boundary condition scheme for the lattice Boltzmann method that has significantly improved stability for modeling turbulent flows while maintaining excellent parallel scalability. Simulations of a three-dimensional lid-driven cavity flow are found to be stable up to the unprecedented Reynolds number $\mathrm{Re}=5\ifmmode\times\else\texttimes\fi{}{10}^{4}$ for this setup. Excellent agreement with energy balance equations, computational and experimental results are shown. We quantify rises in the production of turbulence and turbulent drag, and determine peak locations of turbulent production.

Designing a graphics processing unit accelerated petaflop capable lattice Boltzmann solver: Read aligned data layouts and asynchronous communication
2016
The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently, general-purpose graphics processing units (GPUs) have become available as high-performance computing resources at large scale. We report on designing and implementing a lattice Boltzmann solver for multi-GPU systems that achieves 1.79 PFLOPS performance on 16,384 GPUs. To achieve this performance, we introduce a GPU compatible version of the so-called bundle data layout and eliminate the halo sites in order to improve data access alignment. Furthermore, we make use of the possibility to overlap data transfer between the host central processing unit and the device GPU with com…
Virtuālas ģeogrāfiskas sētas uzstādīšana suņa atrašanās vietas ierobežošanai izmantojot Globālās pozicionēšanas sistēmu
2018
Sistēmas mērķis ir spēja reāllaikā ierobežot suņa pārvietošanos noteiktā virtuālā ģeogrāfiskā sētā pēc iespējas saudzīgākā veidā. Tas tiks panākts izmantojot arduino, akselerometru, GPS moduli, GSM/GPRS moduli, skaņas signālu, ultraskaņas signālu un tīmekļa vietni, kurā būtu iespējams uzstādīt šīs koordinātes un redzēt suņa atrašanās vietu. Šajā kvalifikācijas darbā tika izstrādāta daļa no šīs sistēmas, kas ir tās kodols – suņa ierobežošana ar skaņas signālu balstoties uz GPS un akselerometra datiem.
Virus influenzali H1N1pdm e riassortanti isolati dal suino
2011
Sin dai primi giorni della circolazione del virus pandemico H1N1-2009 nella popolazione, è stata segnalata la trasmissione del virus dall’uomo a specie animali diverse (suino, tacchino, cane, gatto). La trasmissione di virus influenzali dall’uomo agli animali non rappresenta solo un problema limitato al settore zootecnico, ma un problema di sanità pubblica per il ruolo di “serbatoio” dei virus influenzali rappresentato da tali specie. Il suino non ha sinora dimostrato un ruolo epidemiologico importante nella diffusione di (H1N1)pdm all’uomo; tuttavia ciò non esclude, che a seguito dell’evoluzione virale, o di fenomeni di riassortimento, da tale specie emergano e si trasmettano all’uomo viru…
Baculovirus-mediated immediate-early gene expression and nuclear reorganization in human cells
2007
Baculovirus, Autographa californica multiple nucleopolyhedrovirus (AcMNPV), has the ability to transduce mammalian cell lines without replication. The general objective of this study was to detect the transcription and expression of viral immediate-early genes in human cells and to examine the interactions between viral components and subnuclear structures. Viral capsids were seen in large, discrete foci in nuclei of both dividing and non-dividing human cells. Concurrently, the transcription of viral immediate-early transregulator genes (ie-1, ie-2) and translation of IE-2 protein were detected. Quantitative microscopy imaging and analysis showed that virus transduction altered the size of …

Equivalence of viscosity and weak solutions for a $p$-parabolic equation
2019
AbstractWe study the relationship of viscosity and weak solutions to the equation $$\begin{aligned} \smash {\partial _{t}u-\varDelta _{p}u=f(Du)}, \end{aligned}$$ ∂ t u - Δ p u = f ( D u ) , where $$p>1$$ p > 1 and $$f\in C({\mathbb {R}}^{N})$$ f ∈ C ( R N ) satisfies suitable assumptions. Our main result is that bounded viscosity supersolutions coincide with bounded lower semicontinuous weak supersolutions. Moreover, we prove the lower semicontinuity of weak supersolutions when $$p\ge 2$$ p ≥ 2 .
