Vibration analysis using a mobile phone accelerometer

V této bakalářské práci se zabývám otázkou, zda lze pro měření vibrací použít mobilní telefon. Z tohoto důvodu jsem provedl experiment k porovnání dat naměřených mobilním telefonem s hodnotami naměřenými profesionální měřící technikou. Dále jsem se zaměřil na vyhledání nejčastěji používaných akcelerometrů v mobilních telefonech a v neposlední řadě na nalezení a porovnání vhodných aplikací na zaznamenání vibrací mobilním telefonem.The bachelor thesis deals with the question whether or not measurements of vibrations can be taken with a mobile phone. For that purpose I made an experiment to compare data measured with a mobile phone and data measured with professional gauging equipment. I also focused on finding the most commonly used accelometer in mobile phones as well as on finding and comparing suitable mobile apps for recording vibrations with mobile phones.

U radu se istražuje povijest razvoja ornamenata i njihova primjena u namještaju kroz signalizaciju, značenje znakova i vizualnu komunikaciju. Cilj rada je analizom obličja i funkcija objediniti pojedina vremenska razdoblja i primijeniti ih sa područjima rada na Zavodima Šumarskog fakulteta Sveučilišta u Zagrebu Drvnotehnološkog odsjeka. Krajnji rezultat su prijedlozi konceptualnih rješenja primjenom specifičnih ornamentalnih uzoraka, te idejna razrada odabranih signalnih natpisa za svaki Zavod fakulteta

Comparative analysis of the lambda-interferons IL-28A and IL-29 regarding their transcriptome and their antiviral properties against hepatitis C virus.

Specific differences in signaling and antiviral properties between the different Lambda-interferons, a novel group of interferons composed of IL-28A, IL-28B and IL-29, are currently unknown. This is the first study comparatively investigating the transcriptome and the antiviral properties of the Lambda-interferons IL-28A and IL-29. Expression studies were performed by microarray analysis, quantitative PCR (qPCR), reporter gene assays and immunoluminometric assays. Signaling was analyzed by Western blot. HCV replication was measured in Huh-7 cells expressing subgenomic HCV replicon. All hepatic cell lines investigated as well as primary hepatocytes expressed both IFN-λ receptor subunits IL-10R2 and IFN-λR1. Both, IL-28A and IL-29 activated STAT1 signaling. As revealed by microarray analysis, similar genes were induced by both cytokines in Huh-7 cells (IL-28A: 117 genes; IL-29: 111 genes), many of them playing a role in antiviral immunity. However, only IL-28A was able to significantly down-regulate gene expression (n = 272 down-regulated genes). Both cytokines significantly decreased HCV replication in Huh-7 cells. In comparison to liver biopsies of patients with non-viral liver disease, liver biopsies of patients with HCV showed significantly increased mRNA expression of IL-28A and IL-29. Moreover, IL-28A serum protein levels were elevated in HCV patients. In a murine model of viral hepatitis, IL-28 expression was significantly increased. IL-28A and IL-29 are up-regulated in HCV patients and are similarly effective in inducing antiviral genes and inhibiting HCV replication. In contrast to IL-29, IL-28A is a potent gene repressor. Both IFN-λs may have therapeutic potential in the treatment of chronic HCV
