Graafisen käyttöliittymän automaattinen testaus
2012
Tässä kandidaatintutkielmassa tutkitaan graafisten käyttöliittymien automaattista testaamista. Pyritään selvittämään, mitä työkaluja tähän on tarjolla ja miten niiden käyttäminen eroaa toisistaan, sekä mitä elementtejä käyttöliittymästä näillä voidaan testata.
Proton‐Gated Ring‐Closure of a Negative Photochromic Azulene‐Based Diarylethene
2020
Abstract Proton‐responsive photochromic molecules are attractive for their ability to react on non‐invasive rapid optical stimuli and the importance of protonation/deprotonation processes in various fields. Conventionally, their acidic/basic sites are on hetero‐atoms, which are orthogonal to the photo‐active π‐center. Here, we incorporate azulene, an acid‐sensitive pure hydrocarbon, into the skeleton of a diarylethene‐type photoswitch. The latter exhibits a novel proton‐gated negative photochromic ring‐closure and its optical response upon protonation in both open and closed forms is much more pronounced than those of diarylethene photoswitches with hetero‐atom based acidic/basic moieties. …
Transmission and host and mate location in the fish louse Argulus coregoni and its link with bacterial disease in fish
2007
FM Matthias Bandilla osoittaa väitöstutkimuksessaan, että kirjolohen kalatäitartunnalla on selkeä yhteys Flavobacterium columnare -infektioon, joka on yksi ongelmallisimmista bakteeritaudeista suomalaisessa kalanviljelyssä tällä hetkellä. Vaikka heikko kalatäitartunta ei aiheuta kalan kuolemaa, yhdessä bakteerialtistuksen kanssa se voi olla tappava. Vastaavien vuorovaikutusten ymmärtäminen olisi tärkeää vesiviljelyn kannalta, koska erilaisten mikrobien aiheuttamien tautien ja loisten yhteisesiintyminen kalanviljelylaitoksella on ennemminkin sääntö kuin poikkeus.Kalatäi (Argulus coregoni) on pääasiassa lohikaloilla esiintyvä äyriäispintaloinen, jonka levinneisyys ulottuu koko pohjoiselle vyö…
Network Capacity Estimators Predicting QoE in HTTP Adaptive Streaming
2022
The aim of adaptive HTTP streaming technology is preserving the best possible video streaming quality for viewers in heterogeneous network conditions. This can be achieved by making multiple quality versions of the video available. Switching between versions during playback should be imperceptible and fluent. The decision about quality-level switching is typically based on network capacity estimation and buffer occupancy, which predict the risk of stalling. Since quality-level switching and stalling are directly evident to the user, they are often classified as influence factors of quality of experience (QoE). In this paper, we observe different network capacity estimators and buffer behavi…
Search for weakly decaying b -flavored pentaquarks
2018
Investigations of the existence of pentaquark states containing a single $b$ (anti)quark decaying weakly into four specific final states J/$\psi K^+\pi^- p$, J/$\psi K^- \pi^- p$, J/$\psi K^- \pi^+ p$, and $J/\psi \phi (1020) p$ are reported. The data sample corresponds to an integrated luminosity of 3.0/fb in 7 and 8 TeV pp collisions acquired with the LHCb detector. Signals are not observed and upper limits are set on the product of the production cross section times branching fraction with respect to that of the $\Lambda_b$.
Sporotrichoid Cases of Mycobacterium Marinum Skin Infection.
2010
Mycobacterium marinum belongs to the slow growth photochromogenous mycobacteria group. It is pathogenic for fish and human beings in which it can cause cutaneous nodular and ulcerative lesions, sometimes with sporotrichoid arrangement. We report three cases of sporotrichoid Mycobacterium marinum infections successfully treated with prolonged antibiotic therapy. Tropical fish aquaria and, more in general, the water environment were identified as the source of infection.
Densité et mobilité des poissons sous la glace, sur une zone de pêche à la senne de deux lacs finlandais, par écho-intégration.
2000
The density and movements of fish under ice were studied with single-beam mobile surveys and fixed location split-beam surveys, as well as exploratory fishing in winter-seining areas of two shallow Finnish lakes during winter 1999. Fish schooled near the bottom during the day but the schools dispersed and fish ascended at night. Single and split-beam target strength distributions corresponded fairly closely with the length distribution of seine catch samples. Estimated fish densities were greater at night than in daylight. The swimming speed of smelt (Osmerus eperlanus) was 0.18 m·s -1 in daylight and 0.36 m·s -1 at night. The corresponding figures for vendace (Coregonus albula) were 0.11-0…
Regional and age-dependent differences in the effect of wind on the migratory routes of Eleonora's Falcon.
2015
During migration, birds can show different responses to wind in relation to distance to the goal, experience, ecological barriers and visibility of landmarks. We analysed the effect of wind (tailwinds and crosswinds) on daily movement rates (forward and perpendicular) of Eleonora’s falcons using ARGOS satellite telemetry, during their trans-continental autumn migration to Madagascar, in relation to the different crossed regions and individuals’ age class. Our results showed that the effect of wind on daily movement rates was not uniform, being stronger in the farthest region from the migration goal, the Sahara desert, with adults being more affected than juveniles in this region. In the Sah…
Muscle-Tendon Interaction During Human Dolphin-Kick Swimming
2019
Without high impact forces, it is not clear how humans can utilize tendon elasticity during low-impact activities. The purpose of the present study was to examine the muscle-tendon behavior together with the electromyographic (EMG) activities of the vastus lateralis (VL) muscle during the human dolphin-kicking. In a swimming pool, each subject (n = 11) swam the 25 m dolphin-kicking at two different speeds (NORMAL and FAST). Surface EMGs were recorded from the VL and biceps femoris (BF) muscles. Simultaneous recordings of the knee joint angle by electro-goniometer and of the VL fascicle length by ultrasonography were used to calculate the muscle-tendon unit and tendinous length of VL(L-MTU a…
Arm swing during skating at different skiing speeds affects skiing mechanics and performance
2018
Arm swing has been shown to lead to greater maximal speed and movement economy in cross -country skiing. The current study aimed to investigate how arm swing alters skiing mechanics and contributes to performance and acceleration of the athlete’s centre of mass (COM). While skiing on snow seven highly skilled cross -country skiers simulated V2 -alternate skating without using ski poles and with double or single arm swing and without arm swing . During leg push -off the linear momentum of the body increased due to arm swing. Simultaneously, linear momentum of the arm(s) decreased in arm swing trials, indicating a transfer of momentum from arms to the rest of the body and being more prevalent…
