Marine technologies' control networks analysis and optimization for failsafe operations examined for class certification

2014

Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 This thesis presents a suggested solution to improve Marine Technologies (MT) bridgesystems. MT is advancing their technology and use Ethernet as a base. This is new in theoffshore world and certification companies have yet to create clear lines to certify thesenetwork systems. Systems continue to get approved with their current protection, butmeasurements are needed to advance their protection and comply with new demands. Thethesis will go through their current demands and interpret them to optimize MT’s systems andgive the certification companies a clear line to follow. The thesis will analyze MT’s …

Experimental investigation of the kink effect and the low frequency noise properties in pseudomorphic HEMT’s

2005

The kink effect in low-noise pseudomorphic (AlGaAs/InGaAs) HEMT's has been examined in detail by investigating the steady-state and pulsed I-V characteristics, the behavior of the output conductance dispersion and the performance of the gate leakage current to understand its origin. No clear evidence of impact ionization occurrence in the InGaAs channel at kink bias conditions (V-DS.kink = 1.5 V) has been found, thus suggesting that the predominant mechanism should be attributed to trap-related phenomena. A significant rise of the gate current has been found at very high drain voltages (far from V-DS.kink) associated with low drain current values which is probably due to impact ionization o…

Smēķēšanas un perivaskulāro taukaudu savstarpējā mijiedarbība asinsvadu veselībā

2021

Darba mērķis bija novērtēt cigarešu smēķēšanas un perivaskulāro taukaudu ietekmi uz kopējās miega artērijas sieniņas IMT. Pētījumā piedalījās 9 personas vecuma 18-25 gadiem ar atšķirīgu smēķēšanas statusu. Veica antropometriskos mērus ķermeņa svara raksturojumam; ar ultrasonogrāfiju noteica PVAT daudzumu, mērot kopējās miega artērijas EMT; kā arī IMT, ko izmanto aterosklerozes agrīnā diagnosticēšanā. Nelielā pētījuma dalībnieku skaita dēļ, rezultāti tika salīdzināti ar citu zinātnisko pētījumu datiem, kas iegūti ar līdzīgām metodēm. No literatūras analīzes izriet, ka PVAT akumulācija var rosināt artēriju sieniņu sabiezināšanos, savukārt smēķēšana mijiedarbojas ar endotēlija funkciju. Smēķēt…

The individualized music therapy assessment profile as an initial assessment tool of social emotional functioning

2012

An assessment in music therapy clinical practice is an essential part of the therapy process.Based on the assessment the therapist is able to recognize the needs of the client and plan the influential interventions in the therapy. A music therapy assessment evaluates a client´s individual strengths and weakness in both musical and non-musical areas. Many of the music therapy assessment tools have been created for a specific population, not as a comprehensive music therapy assessment tool. The IMTAP is one of the first comprehensive assessment instruments addressing a variety of diagnoses. It has been developed by a team of experienced music therapists in Music Therapy Wellness Clinic at Cal…

Concentration measurements in molecular gas mixtures with a two-pump pulse femtosecond polarization spectroscopy technique

2001

0021-9606; Recently, we have demonstrated the ability of the Raman-induced polarization spectroscopy (RIPS) technique to accurately determine concentration or polarizability anisotropy ratio in low-pressure binary molecular mixtures [E. Hertz, B. Lavorel, O. Faucher, and R. Chaux, J. Chem. Phys. 113, 6629 (2000)]. It has been also pointed out that macroscopic interference, occurring when two revivals associated to different molecules time overlap, can be used to achieve measurements with picosecond time resolution. The applicability of the technique is intrinsically limited to a concentration range where the signals of both molecules are of the same magnitude. In this paper, a two-pump puls…

Moisture source in the Hyblean mountains region (south-eastern Sicily,Italy):Evidence from stable isotopes signature

2006

Abstract Here the authors present results of an isotope study on precipitation collected during a 2-a period from a rain-gauge network consisting of 6 stations located at different elevations in the Hyblean Mountains (HM) region, in south-eastern Sicily. The slope of the local meteoric water line ( δD  = 6.50 δ 18 O + 9.87) obtained for the region suggests that precipitation is affected by evaporation during rainfall events. The main variations in rainwater isotope composition are due to seasonal effects and elevation. An average 2 H excess value of +21.2‰ was found for precipitation events less affected by evaporation (i.e. when the rainfall was >65 mm/month). The spatial distribution of O…

PD-1-induced T cell exhaustion is controlled by a Drp1-dependent mechanism

2020

AbstractPD-1 signalling downregulates the T cell response, promoting an exhausted state in tumor-infiltrating T cells, through mostly unveiled molecular mechanisms. Drp1-dependent mitochondrial fission plays a crucial role to sustain T cell motility, proliferation, survival and glycolytic engagement and, interestingly, such processes are exactly those inhibited by PD-1 in tumor-infiltrating T cells. Here we show that the signature of PD-1pos CD8+ T cells infiltrating MC38-derived murine tumor mass is having downregulated Drp1 activity and more fused mitochondria, compared to PD-1neg counterparts. Also, PD-1pos lymphocytic elements infiltrating human colon cancer rarely express active Drp1. …
