DSP IMPLEMENTATION OF A DIGITAL NON-LINEAR INTERVAL CONTROL ALGORITHM FOR A QUASI-KEYHOLE PLASMA ARC WELDING PROCESSEverett, Matthew Wayne 01 January 2004 (has links)
The Quasi-Keyhole plasma arc welding (PAW) process is a relatively simple concept, which provides a basis for controlling the weld quality of a subject work piece by cycling the arc current between a static base and variable peak level. Since the weld quality is directly related to the degree of penetration and amount of heat that is generated and maintained in the system, the Non-Linear Interval Control Algorithm provides a methodology for maintaining these parameters within acceptable limits by controlling the arc current based upon measured peak current times. The Texas Instruments TMS320VC5416 DSK working in conjunction with Signalwares AED-109 Data Converter provides a hardware solution to implement this control algorithm. This study outlines this configuration process and demonstrates its validity.

Σχεδιασμός συστήματος DSP για επεξεργασία εικόνας με κίνηση σε δύο άξονες και έλεγχο από απόστασηΓκοτσόπουλος, Μιχαήλ 20 September 2010 (has links)
Αντικείμενο της εργασίας αποτελεί η ανάπτυξη συστήματος βασισμένου σε DSP για τη λήψη και επεξεργασία εικόνας υψηλής ανάλυσης με δυνατότητα ρύθμισης της γωνίας λήψης μέσα στο χώρο μέσω πρωτότυπου μηχανισμού που κινείται με τη βοήθεια δύο βηματικών κινητήρων και ελέγχου της διάταξης από απόσταση μέσω σύνδεσης δικτύου με το πρωτόκολλο TCP. Η δικτυακή επικοινωνία, επεξεργασία, μεταφορά και αποθήκευση των δεδομένων εικόνας στηρίζονται στην κάρτα DSK TMS320C6416, που βασίζεται στον DSP 6416 της Texas Instruments, ενώ ο έλεγχος της κάμερας και η οδήγηση των βηματικών κινητήρων επιτυγχάνονται με τη χρήση της θυγατρικής κάρτας DSK-EYE Gigabit, πυρήνα της οποίας αποτελεί ένα FPGA της οικογένειας Cyclone II της ALTERA και περιλαμβάνει τον OV5610 αισθητήρα εικόνας 5.2 Megapixel. Ένα γραφικό περιβάλλον επιτρέπει στο χρήστη της εφαρμογής τον έλεγχο της διάταξης και τη ρύθμιση των παραμέτρων για τη λήψη και επεξεργασία εικόνας ανάμεσα στις οποίες είναι η ρύθμιση φωτεινότητας, κέρδους, ανάλυσης της εικόνας, κατεύθυνσης και γωνίας κίνησηςγια κάθε κινητήρα ξεχωριστά και επιλογή του αλγορίθμου επεξεργασίας της αρχικής εικόνας. / A remote controlled DSP-based system for high resolution image capturing and processing, featuring 2-axis rotational motion was developed using the TMS320C6416 DSK board, which is based on TMS320C6416T DSP. A prototype device holding a pair of bipolar stepper motors and a gear set providing proper gear ratio and holding torque, is used for motion transmission to the 5.2 Megapixel Omnivision OV5610 camera module, connected to the Bitec DSK-EYE Gigabit daughtercard, which is built around a FPGA of the ALTERA Cyclone II family. The remote operation of the whole system is carried out over a network connection via the dedicated Ethernet adapter of the DSK-EYE board, using the TCP/IP protocol. The device is controlled by means of a Graphical User Interface (GUI) which grants access to some key parameters of the image sensoring process, allowing for easy adjustment of gain and exposure values, stepper motor control and image processing algorithm selection

Röstigenkänning genom Hidden Markov Model : En implementering av teorin på DSP / Speech Recognition using Hidden Markov Model : An implementation of the theory on a DSK – ADSP-BF533 EZ-KIT LITE REV 1.5Bardici, Nick, Skarin, Björn January 2006 (has links)
This master degree project is how to implement a speech recognition system on a DSK – ADSP-BF533 EZ-KIT LITE REV 1.5 based on the theory of the Hidden Markov Model (HMM). The implementation is based on the theory in the master degree project Speech Recognition using Hidden Markov Model by Mikael Nilsson and Marcus Ejnarsson, MEE-01-27. The work accomplished in the project is by reference to the theory, implementing a MFCC, Mel Frequency Cepstrum Coefficient function, a training function, which creates Hidden Markov Models of specific utterances and a testing function, testing utterances on the models created by the training-function. These functions where first created in MatLab. Then the test-function where implemented on the DSK. An evaluation of the implementation is performed. / Detta examensarbete går ut på att implementera en röstigenkänningssystem på en DSK – ADSP-BF533 EZ-KIT LITE REV 1.5 baserad på teorin om HMM, Hidden Markov Model. Implementeringen är baserad på teorin i examensarbetet Speech Recognition using Hidden Markov Model av Mikael Nilsson och Marcus Ejnarsson, MEE-01-27. Det som gjorts i arbetet är att utifrån teorin implementerat en MFCC, Mel Frequency Cepstrum Coefficient funktion, en träningsfunktion som skapar Hidden Markov Modeller av unika uttalanden av ord och en testfunktion som testar ett uttalat ord mot de olika modellerna som skapades av träningsfunktionen. Dessa funktioner skapades först i MatLab. Sedan implementerades testprogrammet på DSP:n Texas Instruments TMDS320x6711. Sedan utvärderades realtidstillämpningen. / Nick Bardici, nick.bardici@gmail.com Björn Skarin, bjorn.skarin@exallon.sigma.se

Biodegradation Experiments of Polymeric Materials: Monitoring and Analysis / Bionedbrytning av Polymera Material: Undersökning och AnalysOjala, Sini January 2021 (has links)
Plastskräp har blivit ett global problem på grund av nedskräpning och otillräcklig avfallshantering. Användning av biologiskt nedbrytbart material kan underlätta problemet, även om det inte är en universallösning. Produkter gjorda av biologiskt nedbrytbart material skall ändå till avfallshantering eftersom nedbrytningen kan vara långvarig och variera mycket beroende av omgivningen. Därmed är användningen av biologiskt nedbrytbart material endast berättigat då det är svårt att samla in materialet eller avskilja det från organiskt material. Studiens mål var att undersöka biologiskt nedbrytbara material som kan användas i produkter som fungerar under många olika driftsförhållanden och inte kan återställas efter användning. I den litterära delen av denna studie definieras nedbrytning genom egenskaper och förhållanden som påverkar nedbrytningsprocessen. Nedbrytning av polyestrar och cellulosa och de standardprocessarna som används i nedbrytningsexperimenten betraktades. Standardprocesserna för nedbrytning studerades för att få en klarare inblick i den eftertraktade nedbrytningsgraden och de standardiserade förhållandena för nedbrytningen i olika miljöer. En sammanfattning av olika nedbrytningsexperiment och analysmetoder är också inkluderade för att försäkra att experimenten som utfördes är både giltiga och jämförbara med andra forskningsresultat inom fältet. I detta forskningsprojekt utfördes nedbrytningsexperiment i färskvatten- och hemkompostmiljöer. Målet med projektet var att bedöma ifall materialen kunde brytas ned i ett brett spektrum av miljöer, ifall de var mindre skadliga för naturen än konventionella material som används av dagens industri och för att uppskatta nedbrytningstakten. Nedbrytningstiden var 140 dagar och experimentet utfördes med 10 olika material: betecknade som A-J. Materialen analyserades 8 gånger under nedbrytningsperioden förutom materialen I och J som analyserades en gång efter 140 dagar. Materialen analyserades mekaniskt, strukturellt och termiskt med hjälp av dragprovning, FTIR och DSC. Provernas viktförändring bestämdes också. Nedbrytning observerades visuellt från provernas yta och genom mekaniska prover. Materialen som placerades i hemkomposten visade klara tecken på nedbrytning då färgen hade förändrats och förstärkningsfibrerna hade blivit synliga. Materialen som placerats i hemkompostmiljö visade också klara tecken på tillväxt av mikroorganismer och biomassa som uppstått på ytan av materialen. Sammanfattningsvist, visade materialen B, C och G de mest lovande resultaten med klara tecken på biologisk nedbrytning och de hade en snabbare nedbrytningstakt än de andra materialen som undersöktes. Material D visade klara tecken på biologisk nedbrytning på ytan men dess nedbrytningstakt var uppskattad att vara mycket långsammare. Därmed rekommenderas det att använda material A, B, D och G istället för konventionella icke biologiskt nedbrytbara material. Dessa material har potential att sänka den negativa inverkan och de långsiktiga riskerna av plastskräp för miljön. / Plastic debris has become a global crisis due to littering and misplaced waste management. The use of biodegradable materials can ease the problem, but it is not always the answer. Products made of biodegradable materials are still to be waste managed since biodegradation can be a long process and is highly dependent on the environment conditions. Hence, the use of biodegradable materials is justified only when retrieving the product after use is impossible or prohibitively expensive or separating it from organic matter is difficult. This study was made to investigate biodegradable materials that can be used in products that are operating in broad range of operational conditions and cannot be retrieved back after use in most cases. In the literature part of this study the biodegradation is defined along with properties and conditions that affect the biodegradation process. Biodegradation of polyesters and cellulose, and standards used in the biodegradation experiments were reviewed. Biodegradation standards were studied in order to have a clearer picture of the pursued degree of biodegradation and standardized properties in the biodegradation experiments. Review of different biodegradation tests and analysis methods are included as well to ensure that the experiments performed in this work are valid and comparable with other biodegradation studies. In this study, the biodegradation experiment was conducted in freshwater and home compost environments. The aim was to determine if the materials were able to biodegrade in wide range of environments, to make sure they are less harmful than the conventional materials used in the industry and to estimate the rate of biodegradation. The duration of the experiments were 140 days with 10 different materials: A – J. The materials were analyzed 8 times during the aging period, except materials I and J, which were analyzed only once after 140 days. The samples were analyzed mechanically, structurally, and thermally using tensile test, FTIR and DSC measurements, respectively. Also, the samples weight changes were analyzed. The degradation was visually observed from the surfaces of the samples and from mechanical testing in both experimental environments. Home compost environment showed clear signs of biodegradation where reinforcement fibers became visible and changed the color of some of the samples. Also, home compost samples had microorganisms growing on them, and biomass was developing around them. To conclude, material B, C and G had the most promising results with clear signs of biodegradation and had faster estimated biodegradation rate compared with the other studied materials. Material D had signs of biodegradation on the surface as well. However, the biodegradation rate was estimated to be much slower. In conclusion, it is recommended to use the studied materials A, B, D and G instead of the conventional non-biodegradable polymers. These materials have potential to lower the negative impact and long-term risks of plastic debris to the environment.
