Application independent greedy particle tracking method for 3D fluorescence microscopy image series

2012

Single-particle tracking is computationally a challenging problem, and usually solved with local methods. Local methods suffer from defects in the image data or in the detection of particles, such as temporal disappearing of particles. A particle tracking method has to provide a solution also to real disappearing and appearing of particles as a result of merging and splitting. Here, we present an efficient, greedy algorithm as a solution to the particle tracking problem. This improved local method is application independent, as it has high configurability of the function used to solve particle correspondence. To demonstrate the accuracy of the method, we apply it to real microscopy image da…

PENGAJARAN APRESIASI NILAI-NILAI CERITA RAKYAT “EMPAT RAJA” DALAM PEMBELAJARAN BAHASA INDONESIA SEBAGAI MODEL PEMBELAJARAN KONTEKSTUAL DI KABUPATEN R…

2016

The main focus of the research is to reveal educative values contained in Empat Raja “Four Kings” Folklore. It is hoped that this research can serve as an Indonesian language teaching medium with contextual learning model containing local or Papuan literatures, especially folklores from Raja Ampat areas. Contextual learning model is a model in implementing literature appreciation learning which helps the teachers to tie the materials and students' real world. The method used in this research was descriptive-qualitative with data collection which were obtained from Empat Raja “Four Kings” folklore. The data were collected by usinginterview and observation technic and were analyzed by using v…

Individual and shared digital repertoires : older adults managing digital services

2023

The rise of public and other non-recreational digital services is based on the idea of catering to the daily needs of the citizens cost-efficiently and with ease. Previous research has approached the use of digital services mainly from the perspective of an individual, while the significance of shared practices of use has attracted only a little attention. In this article, we (1) examine the incentives and limitations associated with the use of non-recreational digital services, which either encourage or discourage older adults to use them. Based on the first question, we then ask (2) how older adults in this study manage those non-recreational digital services they have chosen to use. Our …

Visibility in mediated borderscapes : The hunger strike of asylum seekers as an embodiment of border violence

2018

In 2012, two Afghan asylum seekers camped outside the Parliament building in Helsinki during a hunger strike that lasted for 72 days. Although the protest was very visible in the city space, the mainstream media and most politicians ignored it. This paper analyzes the protest and its mediation through the concepts of borderscape and visibility. Using methods of visual and discourse analysis, we examine the ways in which the hunger strike protest – and its mediation – negotiate the (in)visibility of borders. We show how the city can be a site for both policing and for politicizing asylum issues. In particular, we focus on the ways in which protesting asylum seekers embody borders and border …

Robust optimality of linear saturated control in uncertain linear network flows

2008

We propose a novel approach that, given a linear saturated feedback control policy, asks for the objective function that makes robust optimal such a policy. The approach is specialized to a linear network flow system with unknown but bounded demand and politopic bounds on controlled flows. All results are derived via the Hamilton-Jacobi-Isaacs and viscosity theory.

Agent-based model for the rescheduling of Individual and collective daily activities under uncertainties

2020

Daily activity schedule are popular for people duringdaily life. While, when executing the schedule on the real road network, there are always some disruptions disturbing the planned schedule. To deal with this problem, daily activity rescheduling is necessary. This thesis regards the disruptions from the activity schedule execution environment as unexpected events (uncertainties). It establishes agent-based models to simulate the activity rescheduling decision process from the aspects of individual activity rescheduling and joint trip renegotiating.For the individual activity rescheduling, the model in this thesis wants to explore the relationship between a pair of episodes (two connected …

Charge transport through spin-polarized tunnel junction between two spin-split superconductors

2019

We investigate transport properties of junctions between two spin-split superconductors linked by a spin-polarized tunneling barrier. The spin-splitting fields in the superconductors (S) are induced by adjacent ferromagnetic insulating (FI) layers with arbitrary magnetization. The aim of this study is twofold: On the one hand, we present a theoretical framework based on the quasiclassical Green's functions to calculate the Josephson and quasiparticle current through the junctions in terms of the different parameters characterizing it. Our theory predicts qualitative new results for the tunneling differential conductance, $dI/dV$, when the spin-splitting fields of the two superconductors are…

Magnetic field-controlled 0−π transitions and their experimental signatures in superconductor-ferromagnet-superconductor junctions

2019

Superconductor-ferromagnet-superconductor Josephson junctions are known to exist in the $0$ and $\pi$ states with the transitions between them controlled by the temperature and ferromagnetic interlayer thickness. We demonstrate that these transitions can be controlled also by the external magnetic field directed perpendicular to the layers. By varying the ratio of diffusion coefficients in superconducting and ferromagnetic layers, these field-controlled transitions can be made detectable for arbitrary large value of the exchange energy in the ferromagnet. We also show that the $0$-$\pi$ transitions in the perpendicular field can be observed as the specific features of the flux-flow conducti…
