Development of support and drive systems for defiberization drum

Diplomityön tarkoituksena oli kuidutusrumpulaitteiston käytön- ja kannatuksen kehittä-minen. Työ rajattiin laajuutensa vuoksi koskemaan tuotesarjan viittä pienintä kokoa. Työn alkuosassa käsitellään kuidutuksen teoriaa ja siihen soveltuvia laitteistoja. Käytön suunnittelun kannalta olennaista käynnistystehon tarvetta on tarkasteltu lähtökohdaisesti fysiikan avulla. Perustietoja teorialle on haettu aiemmista tutkimuksista sekä kirjallisuu-desta. Tarkastelun tuloksena teoriaa on kehitty ja se on saatu vastaamaan todellisuutta aiempaa paremmin. Kannatuksen ja käytön toteuttamisvaihtoja etsittäessä on käytetty systemaattisen koneen-suunnittelun keinoja. Saatuja ideoita on arvioitu teknillis-taloudellisin perustein ja näistä on valittu parhaat vaihtoehdot jatkokehitykseen. Jatkokehitysvaiheessa ratkaisuvaihto-ehtoja on tarkasteltu komponenttitasolla ja näistä on tehty yksityiskohtaiset kustannus-laskelmat. Työn tuloksena on esitetty kannatuksen ja käytön toteutusvaihtoehto, jonka avulla voidaan saavuttaa merkittäviä kustannussäästöjä. Korkea, 30 prosentin kustannussäästö-tavoite saavutettiin.

Development and Analysis of a Drum-Shaped Compact Microstrip Antenna

The thesis is the outcome of the experimental and theoretical investigations on a new compact drum-shaped microstrip antenna. A new compact antenna suitable for personal communication system(PCS), Global position System(GPS) and array applications is developed and analysed. The generalised cavity model and spatial fourier transform technique are suitably modified for the analysis of the antenna. The predicted results are compared with experimental results and excellent agreement is observed. The experimental work done by the author in related fields are incorporated as three appendices in this thesis. A single feed dual frequency microstrip antenne is presented in appendix A.Appendix B describes a new broadband dual frequeny microstrip antenna. The bandwidth enhancement effect of microstrip antennas through dielectric resonator loading is demonstarted in Appendix C.

Food of the Red Drum, Sciaenops ocellata, from Mississippi Sound

Examined digestive tracts of the red drum in Mississippi Sound contained mostly decapod crustaceans. Crustaceans accounted for 34 of 59 encountered taxa, more than reported from any other region. Nevertheless, the general diet for 104 fish with food contents out of the 107 examined is similar to that reported for red drum in several other studies from other areas. In addition to crustaceans, fishes followed by polychaetes occurred as the most important items (in 99, 43, and 15% of the drum with food, respectively). Blue crabs occurred in even more drum than the frequently encountered penaeid shrimps. Other commercial species were negligible in the diet. Sixteen large drum from Georgia beaches were also examined; unlike those from Mississippi, many of these contained echinoderms, but not polychaetes or penaeids. We suggest that the red drum’s migrations may be regulated by optimal abundance of specific types of dietary organisms.

Population biology of the barbel drum Ctenosciaena gracilicirrhus (Metzelaar, 1919) (Perciformes: Sciaenidae) in Caraguatatuba Bay, Southeastern Brazil

This study evaluated the population biology of Ctenosciaena gracilicirrhus (Perciformes: Sciaenidae) in a shallow non-estuarine coastal area of southeastern Brazil. Monthly samples were taken from October 2003 through October 2004, in two distinct areas at depths from 1 to 4 m. C. gracilicirrhus was generally among the most abundant fish species during the period. Its density was significantly higher in a single sampling month, May 2004, in the South area, which may be explained by its migratory behavior together with its preference for deeper areas. Such behavior may lead to bias in community estimates that use few or only seasonal samples. C. gracilicirrhus individuals ranged from 4.0 to 10.2 cm long, with a main mode from 7.5 to 9.0 cm and a significant decrease in mean size from June onward. The estimation of body growth parameters was compromised by this population feature. Similarly, the prey spectrum was difficult to determine because of the deteriorated condition of the stomach contents, although crustaceans were clearly the most important items ingested. Amphipoda was the only subgroup that could be identified more precisely, mainly by the construction of their tubes.

Can You Hear the Shape of a Drum?

If you had perfect pitch and listened to a recording of the sounds a drum made when struck, could you determine the shape of the drum? This question is an example of an inverse problem; inverse problems arise in medical imaging, oil prospecting, spectroscopy, and many other fields. We’ll first discuss the analogous question in the simpler setting of plucking a string. Then we’ll tackle the problem for drums and see that there are some surprises. Finally, I will give a brief indication of how this problem relates to some of my recent research. The emphasis will be on the ideas rather than on the technical details, so there will be pretty pictures instead of equations.

Social Networking Obliterates Etiquette: Thumbs Drum in Rise of Multitasking Rudeness

This pilot study investigates selected etiquette issues that appear to have arisen with the prevalence of hand-held electronic communications. Researchers surveyed college undergraduates, graduates, and faculty about the appropriateness of multitasking when others are present, whether they thank people with a hand-written note, by telephone, or by email, and the appropriateness of their preferred means of saying thank you. This study raises questions about etiquette issues when using electronic communications.
