This project deals with implementation of a first order Sigma–Delta AD converter on the FPGA. This ADC is design for an audio signal processing. ADC is build up partially from digital blocks implemented in FPGA (programmed using VHDL) and from few analog components placed external to FPGA. Output from ADC is PCM signal. Data from ADC is created UDP datagram, which is sent to PC via network connection. Income data are received in created program, which save data to text file. This text file is processing in MATLAB.

Machine-to-Machine (M2M) communications are used for several purposes, forinstance to transmit information derived from measurements collected frommonitoring instruments. M2M communications also allow intelligent devices toexchange real-time data without human intervention. Through a literaturesurvey regarding M2M, Mobile Communications, and Communication Protocolsfor M2M, such as the Constrained Application Protocol (CoAP), we found thatthe CoAP-UDP model is more suitable for M2M systems, than the HTTP-TCPapproach. Additionally, CoAP supports a DTLS implementation to provide endto-end security to protect communications. Consequently, CoAP was the selectedtechnology that allowed us to achieve the goal of designing a low-cost, scalable,secure, and standard-based communication solution for the company supportingthe project: Solelia Greentech. This company is the largest provider inScandinavia of solar chargers for electrical vehicles. The development andexperimental implementation of this solution was also successfully accomplished.We created a prototype that is able to gather information from a pulse generator(e.g. smart meter), process the data, run a CoAP server, and transmit dataresources to CoAP clients through a secure DTLS channel. Furthermore, aperformance analysis of the system and other existing Web server alternativeswas performed. As a result of this process, we concluded that the CoAP serverwe developed reaches between four and seven times higher throughputs than thecompared systems. Therefore, this project represents a viable alternative forexisting solutions on the market. / Machine-to-machine (M2M) kommunikation används för flera syften, till exempel överföra information från mätningar som samlats in från övervakningsprogram instrument. M2M kommunikation gör det också möjligt att intelligenta enheter utbyter data i realtid utan mänsklig inblandning. Genom en litteraturstudie om M2M, mobil kommunikation, och kommunikationsprotokoll för M2M, såsom Constrained Application Protocol (CoAP), fann vi att CoAP-UDP-modellen är mer lämpade för M2M-system, än HTTP-TCP strategi. Dessutom, CoAP stöder ett DTLS genomförande som bidrar med end-to-end säkerhet för att skydda kommunikation. Följaktligen CoAP var den valda tekniken som tillät oss att uppnå målet att utforma en billig, skalbar, säker och standardbaserad kommunikationslösning för företag som stödde projektet: Solelia Greentech. Detta företag är den största leverantören i Skandinavien av solar laddare för eldrivna fordon. Utveckling och experimentella genomförande av denna lösning var också lyckat fulländad. Vi skapade en prototyp som kan samla information från en pulsgenerator (t.ex. smarta mätare), process data, köra en CoAP server, och överföra dataresurser till CoAP-klient genom en säker DTLS kanal. En prestandaanalys av systemet och andra befintliga webbservern alternativ utfördes. Som en följd av denna process, vi drog slutsatsen att CoAP servern vi utvecklat når mellan fyra och sju gånger högre genomloppstid än de jämförda systemen. Därför Detta projekt är ett lönsamt alternativ för befintliga lösningar på marknaden.

Avena sativa L. (2n = 6x = 42, AACCDD genome composition) or common oat is the cereal grain possessing the highest levels of water-soluble seed (1-3,1-4)-β-D-glucan (β-glucan), a hemicellulose important to human health due to its ability to lower serum LDL cholesterol levels. Understanding the mechanisms of β-glucan accumulation in oat endosperm is, consequently, of great interest. We report a genome-wide association study (GWAS) to identify quantitative trait loci (QTLs) controlling β-glucan production in oat, identifying 58 significantly associated markers. Synteny with the barley (Hordeum vulgare L.) genome identified four major regions of interest, the CslF and CslH gene families along with UGPase and AGPase as candidate genes. Subgenome-specific expression of the A, C, and D homoeologs of major β-glucan synthase AsCslF6 revealed that AsCslF6_C is the least expressed in all tissue types and time points, with low-β-glucan varieties recording the highest proportion of AsCslF6_C expression. In order to further investigate the candidate genes identified in our GWAS study and gain a greater understanding of the other cell wall polysaccharides that comprise the total fiber content in oat we sought to characterize five additional genes. Accordingly, we cloned and sequenced the three homoeologs of AsUGP and AsAGPS1. AsAGPS1 is the small subunit 1 gene of the enzyme ADP-glucose pyrophosphorylase (AGPase), which is responsible for catalyzing the first committed step in the starch biosynthesis pathway through the production of ADP-glucose. AsUGP is the gene the codes for UDP-glucose pyrophosphorylase (UGPase) an enzyme responsible for the reversible production of UDP-glucose (UDPG). UDPG is used directly or indirectly as a precursor for the biosynthesis of cell wall polysaccharides. In high β-glucan mutant line ‘OT3044’ we observed increased expression of AsUGP with a corresponding reduction of AsAGPS1 expression. Similarly, we observed an inverse expression pattern in low-fiber mutant line ‘OT3018’, wherein AsUGP expression was decreased in favor of AsAGPS1 expression. Further, we also found evidence that these changes in both AsUGP and AsAGPS1 expression are due primarily to up- or down-regulation in the A-genome homoeoalleles. Additionally, we characterized genes in the CslC family (CslC4, CslC9) and CslA family (CslA7) responsible for xyloglucan and glucomannan synthesis, respectively. High-fiber line ‘HiFi’ showed the least amount of overall expression of these three genes, raising the possibility that the increased β-glucan is due to a reduction in other hemicelluloses. After analyzing homoeolog-specific expression in multiple genes we observed that the A genome consistently had the most highly expressed homoeoallele, hinting at a universal preference for expression of this subgenome. We present hypotheses regarding multiple points in carbohydrate metabolism having the potential to alter β-glucan content in oat.

The goal of the project was to create independent system, which is able to supervise remote site using Ethernet network. It can measure temperature and check state of door magnetic contact. Gained information are sent over network to the cenral node, which is able to present them on web page. In the project are also discussed important network protocols needed for implementation of the system, hardware used for implementation and software of the system.
