Σχεδιασμός και κατασκευή ηλεκτροακουστικού συστήματος απόδοσης χαμηλών συχνοτήτων

Σταματάκης, Ιωάννης 01 October 2012 (has links)
Η αναπαραγωγή χαμηλών συχνοτήτων γίνεται διαμέσου ηχείων μεγάλου όγκου και μεγαφώνων μεγάλης διαμέτρου κώνου και μεγάλης μαγνητικής επαγωγής. Είναι δυνατός ο διαχωρισμός του φάσματος χαμηλών συχνοτήτων σε τρεις περιοχές και η αναπαραγωγή της κάθε περιοχής από ξεχωριστό ηχείο. Λογω της χαμηλής ανάλυσης του ανθρωπίνου συστήματος ακοής στις χαμηλές συχνότητες, η ανακατασκευή του φάσματος χαμηλών συχνοτήτων από τα τρία ηχεία δεν είναι απαραίτητο να είναι επίπεδη. Έτσι το κάθε ηχείο περιλαμβάνει ειδικό μεγάφωνο το οποίο αναπαράγει σε υψηλή στάθμη κοντά στη συχνότητα συντονισμού του. Το μεγάφωνο αυτό μπορεί να έχει μικρή διάμετρο και μικρή μαγνητική επαγωγή που σημαίνει μικρών διαστάσεων μαγνήτη και μπορεί να εγκατασταθεί σε καμπίνα μικρού όγκου. Έτσι το φάσμα χαμηλών συχνοτήτων αναπαράγεται από σύστημα μειωμένων διαστάσεων σε σχέση με το συνηθισμένο και με υψηλότερη απόδοση. Η σχεδίαση και η κατασκευή ενός τέτοιου συστήματος αναπαραγωγής χαμηλών συχνοτήτων είναι το αντικείμενο της παρούσας εργασίας. / Low frequency reproduction can be done through large dimention loudspeakers and big magnetic force. Low frequency spectrum can be divided into three small regions and each one can be reproducted via independent loudspeakers. Because of the low resolution of the human auditory system in such frequencies, it's not necessary for the frequency response to be flat. Each speaker has a specially designed loudspeaker with high sensitivity at the resonance frequency. The resulted speaker will have small dimentions. The final system will have smaller overall dimentions compared to the usual basswoofers. The design and construction of such a system is the sybject of the thesis.

Three Newly Commissioned Works for Bass Clarinet: A Recording and Performance Practice Guide

January 2012 (has links)
abstract: New works for the bass clarinet as a solo instrument are uncommon. In the interest of expanding the repertoire of the bass clarinet, three new works for bass clarinet were commissioned from three different composers, all with different instrumentations. The resulting works are Industrial Strength for bass clarinet and piano by Kenji Bunch; Dark Embers for two bass clarinets by Theresa Martin; and Shovelhead for bass clarinet and interactive electronics by Steven Snowden. Although all three works feature the bass clarinet, they are all very different and pose unique challenges to the performer. To accompany these pieces, and as an aid to future performers, a performance practice guide has been included with recommendations for individuals who wish to perform these works. Included in the guide are recommended fingerings, practice techniques, and possible adjustments to the bass clarinet parts designed in collaboration with the composers that make the works more technically accessible. Accompanying this guide are full scores of all three works, a recording of them performed by the author, and a chart that contains recommended altissimo fingerings. / Dissertation/Thesis / D.M.A. Music 2012

Foram realizadas análises hematológicas e parasitológicas de 159 peixes, sendo 20 espécimes selvagens e 20 cultivados em cada estação do ano. Pseudorhabdosynochus beverleyburtonae foi o parasito mais abundante, com as maiores intensidades e dominância relativa média em todas as estações. Neobenedenia melleni foi observado em todas as estações, com aumento gradativo do número de parasitos das estações mais frias para as mais quentes e maiores prevalências e intensidades médias no verão. Helicometrina nimia, com exceção dos peixes selvagens no verão foi encontrado em todas as estações. Pseudempleurosoma sp. e larvas de Contracaecum sp. apresentaram prevalências baixas e ocorreram em peixes selvagens e cultivados no outono e primavera, respectivamente. Os maiores valores no percentual de hematócrito em peixes de cultivo, contagem total de eritrócitos e leucócitos nos peixes de ambas as origens, redução no número de trombócitos em peixes selvagens e de linfócitos nos peixes cultivados, além das maiores prevalências e intensidades médias de infecção por N. melleni ocorreram no verão. No outono, ocorreram as maiores intensidades médias de infecção por P. beverleyburtonae nos peixes de ambas as origens, além da maior contagem total de trombócitos em peixes selvagens, redução no número de linfócitos e aumento no número de monócitos nos peixes cultivados. Estes resultados sugerem que N. melleni possui maior influência sobre as características sanguíneas da garoupa verdadeira quando comparado a P. beverleyburtonae e que altas intensidades de parasitos potencialmente patogênicos podem favorecer surtos de doenças em condições de cultivo desta espécie.

ALTERNATIVE FEEDING STRATEGIES TO MAXIMIZE MARINE FEEDSTUFF REPLACEMENT IN LARGEMOUTH BASS Micropterus salmoides CULTURE WHILE MAINTAINING PRODUCTION PERFORMANCE

Coursey, Andrew Richard 01 August 2011 (has links)
ANDREW R. COURSEY, for the Master of Science degree in Zoology, presented 24 June 2011 at Southern Illinois University Carbondale TITLE: ALTERNATIVE FEEDING STRATEGIES TO MAXIMIZE MARINE FEEDSTUFF REPLACEMENT IN LARGEMOUTH BASS Micropterus salmoides CULTURE WHILE MAINTAINING PRODUCTION PERFORMANCE Advisors: Chris Kohler and Jesse Trushenski Harvest of marine resources for feedstuff production is at its maximum sustainable yield and alternative feedstuffs are needed to supply livestock production for an expanding human population having a growing desire for seafood. Aquaculture is currently the fastest growing sector of agriculture, but the high cost and limited supplies of marine feedstuffs for aquafeeds could ultimately limit production of foodfish. Replacement of marine feedstuffs poses a dilemma, however, as replacement of fish meal can affect animal growth, and replacement of fish oil in aquafeeds leads to altered fillet fatty acid profiles without the maximum benefit of high omega-3 (n-3) and long-chain polyunsaturated fatty acids (LC-PUFA) content. Two feeding trials were conducted to determine if poultry byproducts can replace fish meal and fish oil in diets for largemouth bass Micropterus salmoides without affecting production performance or fillet fatty acid composition. Poultry byproducts were able to replace fish meal and fish oil while maintaining production performance of largemouth bass, however, the altered fatty acid profiles of the feeds were reflected in the fillets. Finishing diets containing high levels of fish oil were implemented to restore n-3 and LC PUFA concentrations in the fillet. Twelve weeks of finishing proved suitable to partially restore n-3 and LC-PUFA concentrations while limiting the overall use of marine resources in the largemouth bass production cycle.

Population Demographics, Connectivity, and Recruitment Sources of Spotted Bass in Smithland Pool of the Ohio River

Abell, Nicholas 01 December 2017 (has links)
Understanding spatial patterns in population demographics and the principal natal environments supporting riverine fish populations are important for fisheries management. Although the black basses are among the most popular groups of game fishes in North America, relatively little information exists regarding demographics and environmental history of spotted bass Micropterus punctulatus in riverine environments. Fin ray microchemistry was used to identify natal environment and age estimates from sectioned fin rays used to estimate growth and mortality rates for spotted bass in Smithland pool of the Ohio River and three tributaries. Spotted bass were collected from 2014-2016 in headwater reaches of tributaries using electrofishing, angling, and a seine net, while electrofishing was used exclusively in the Ohio River and lower tributary reaches. Spotted bass in the Ohio River generally lived longer and grew larger than conspecifics in tributaries, although mortality rates were not definitively different. Differences in water Sr:Ca and Ba:Ca among the Ohio River and tributaries were reflected in fin rays from age-0 and age-1 fish. Eighteen percent of spotted bass ≥ age-2 captured in the Ohio River originated in tributaries, whereas 15% captured in tributaries originated in the Ohio River. Although most fish remained in their natal environment, small tributaries can be a supplemental recruitment source for spotted bass populations and fisheries in large rivers. This study highlights the utility of fin rays for microchemical analysis and age estimation of spotted bass.
