A Time-Non-Homogeneous Double-Ended Queue with Failures and Repairs and Its Continuous Approximation
2018
We consider a time-non-homogeneous double-ended queue subject to catastrophes and repairs. The catastrophes occur according to a non-homogeneous Poisson process and lead the system into a state of failure. Instantaneously, the system is put under repair, such that repair time is governed by a time-varying intensity function. We analyze the transient and the asymptotic behavior of the queueing system. Moreover, we derive a heavy-traffic approximation that allows approximating the state of the systems by a time-non-homogeneous Wiener process subject to jumps to a spurious state (due to catastrophes) and random returns to the zero state (due to repairs). Special attention is devoted to the cas…

Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses
2021
The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…
Vertex corrections for positive-definite spectral functions of simple metals
2016
We present a systematic study of vertex corrections in the homogeneous electron gas at metallic densities. The vertex diagrams are built using a recently proposed positive-definite diagrammatic expansion for the spectral function. The vertex function not only provides corrections to the well known plasmon and particle-hole scatterings, but also gives rise to new physical processes such as generation of two plasmon excitations or the decay of the one-particle state into a two-particles-one-hole state. By an efficient Monte Carlo momentum integration we are able to show that the additional scattering channels are responsible for the bandwidth reduction observed in photoemission experiments on…
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.
Lipid Binding Controls Dimerization of the Coat Protein p24 Transmembrane Helix
2019
Abstract Coat protein (COP) I and COP II complexes are involved in the transport of proteins between the endoplasmic reticulum and the Golgi apparatus in eukaryotic cells. The formation of COP I/II complexes at membrane surfaces is an early step in vesicle formation and is mastered by p24, a type I transmembrane protein. Oligomerization of p24 monomers was suggested to be mediated and/or stabilized via interactions within the transmembrane domain, and the p24 transmembrane helix appears to selectively bind a single sphingomyelin C18:0 molecule. Furthermore, a potential cholesterol-binding sequence has also been predicted in the p24 transmembrane domain. Thus, sphingomyelin and/or cholestero…
Few-body insights of multiquark exotic hadrons
2018
In this contribution we discuss the adequate treatment of the $4-$ and $5-$body dynamics within a constituent quark framework. We stress that the variational and Born-Oppenheimer approximations give energies rather close to the exact ones, while the diquark approximation might be rather misleading. Hall-Post inequalities provide very useful lower bounds that exclude possible stable states for some mass ratios and color wave functions.
Taloyhtiöistä tulevaisuuden energiatuottajia : muutospolut vuoteen 2035 ja murrosareena tiedon yhteistuotannon menetelmänä
2020
Noin neljännes Suomen asuntokannasta koostuu taloyhtiöistä. Niistä merkittävä osa tarvitsee lähivuosina korjauksia, joiden avulla voidaan kehittää rakennuskannassa tapahtuvaa hajautettua energiantuotantoa esimerkiksi aurinkopaneelien ja lämpöpumppuratkaisujen avulla. Vuonna 2018 voimaan tullut EU:n energiayhteisösääntely luo yhdessään meneillään olevat kansallisten sääntelymuutosten kanssa perustan, jonka varassa taloyhtiöt voivat vahvistaa kansalaisten energiantuottajaroolia tulevaisuudessa. Murros taloyhtiöiden kestävään energiantuotantoon on haaste, joka edellyttää useiden yhteiskunnan osa-alueiden näkökulmien ja toimijoiden kokoamista yhteen. Tätä tavoitetta varten järjestettiin vuonna …
Statistical Approximation of Fourier Transform-IR Spectroscopy Data for Zinc White Pigment from Twentieth-Century Russian Paintings
2017
We present a statistical model for approximation of experimental Fourier transform-IR spectroscopy (FTIR) data for paint samples from paintings of different ages. The model utilizes random variations in some parameters (initial ageing rate, degree of change in ageing rate and time at which the change occurs). We determine the parameters characterizing variation in the paint composition and the storage conditions for the paintings. The numerical calculation is qualitatively consistent with the experimental data. In the proposed model, changes in the initial composition of the paint and the storage conditions make about the same contribution to the experimentally observed scatter in the data …
Sakē popularitātes kritums Japānas modernajā sabiedrībā: iemesli un risinājumi
2017
Bakalaura darba nosaukums ir “Sakē popularitātes kritums Japānas modernajā sabiedrībā: iemesli un risinājumi”. Šajā darbā autore ir izpētījusi sakē vēsturi no seniem laikiem līdz mūsdienām. Darba mērķis ir uzzināt iemeslus sakē popularitātes kritumam mūsdienu Japānā kā arī izprast, ko sakē nozīmē Japāņiem. Inovāciju parādīšanas Japānā nenozīmēja veco, tradicionālo vērtību aizmiršanu. Japānas sabiedrībā vecais un jaunais daudzos gadījumos ir gājis roku rokā. Viens no pierādījumiem tam ir šajā darbā aprakstītais fenomens, ka mūsdienu japāņi dzer gan tradicionālo sakē, gan importētos dzērienus. Bakalaura darbs sastāv no 50 lpp. Tajā ir 3 nodaļas. Pirmajā nodaļā stāstīts par vispārējo sakē vēst…
