A single-station method for the detection, classification and location of fin whale calls using ocean-bottom seismic stations
No full textPassive seismic monitoring in the oceans uses long-term deployments of Ocean Bottom Seismometers (OBSs). An OBS usually records the three components of ground motion and pressure, typically at 100Hz. This makes the OBS an ideal tool to investigate fin and blue whales that vocalize at frequencies below 45Hz. Previous applications of OBS data to locate whale calls have relied on single channel analyses that disregard the information that is conveyed by the horizontal seismic channels. Recently, Harris, Matias, Thomas, Harwood, and Geissler [J. Acoust. Soc. Am. 134, 3522-3535 (2013)] presented a method that used all four channels recorded by one OBS to derive the range and azimuth of fin whale calls. In this work, the detection, classification, and ranging of calls using this four-channel method were further investigated, focusing on methods to increase the accuracy of range estimates to direct path arrivals. Corrections to account for the influences of the sound speed in the water layer and the velocity structure in the top strata of the seabed were considered. The single station method discussed here is best implemented when OBSs have been deployed in deep water on top of seabed strata with low P-wave velocity. These conditions maximize the ability to detect and estimate ranges to fin whale calls.Peer reviewe
Educação cigana: entre-lugares entre escola e comunidade étnica
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Gradução em EducaçãoO presente trabalho traz a apresentação e análise sobre a etnia cigana, tendo em vista três enfoques principais: O primeiro, relata os principais aspectos da história dos ciganos no mundo e no Brasil. O segundo enfoque, apresenta alguns dispositivos legais da Constituição de 1988 e os atuais processos de interlocução dos ciganos com as Políticas Públicas brasileiras. O terceiro enfoque relata os contextos educativos intra-grupo e algumas reflexões sobre os mesmos. Também apresenta o relato de um estudo de caso, realizado com uma família cigana residente no município de Palhoça/SC/ Brasil, suas idéia sobre educação e que valores atribuem à escola formal e à comunidade étnica. A metodologia de pesquisa consistiu em: revisão bibliográfica; trabalhos de campo e aplicação de entrevistas. Pela própria complexidade que envolve o tema, foi que não optamos por nenhum referencial teórico específico, mas buscamos estabelecer um grupo de autores com os quais nos identificamos, e que, poderiam contribuir com nossas reflexões e inquietações. Foram eles: Alberto Melucci; Cliford Geertz; Homi Bhabha; Paulo Freire; Luiza Cortesão; Márcia Ondina Ferreira; Reinaldo Matias Fleuri; José Marin; Tomaz Tadeu Silva; Paola Falteri; Nadir Esperança Azibeiro e Francesco Susi, dentre outros. De acordo com as observações realizadas constatamos preliminarmente que: A questão da influência das sociedades não-ciganas, na identidade étnica cigana, foi e continua sendo historicamente uma grande preocupação dos ciganos; que em nível mundial, e particularmente no Brasil, já existem políticas públicas para as minorias étnicas, dentre elas a cigana; que os ciganos vêm mantendo uma relação com a escola, mesmo que fragmentada e fragilizada; que apesar dos ciganos reconhecerem a necessidade de freqüentarem a escola como forma de se alfabetizarem, o maior valor a que eles atribuem, é a relação intra-étnica, portanto, a sua própria cultura
Regional Products, Regions' Reputation and Commercial Strategies: A Tale of Two Cheese Suppliers
No full textNetworks of firms producing and selling regional products to domestic and foreign markets are influencing the direction and options of local development. Regional products are embedded in historical tradition and geographic, cultural and social specificity. Most of the local activities are performed by clustered SME's in well defined geographical areas. To study the mechanisms and factors which favour spontaneous development in specific areas and make SME's competitive through cluster development we used case study methodology. An evolutionary perspective of "Casa Matias" and "Casa dos Queijos", two portuguese SME's, is expected to illustrate which key factors triggered the firm's cheese business and, simultaneously, examine organisational practices with particular emphasis on cluster formation and internationalisation process. From this analysis we expected to conceptualise a specific policy scheme to help developing spontaneous entrepreneurship, cooperation between clustered SME's and local collective development.

Passiivisen UHF RFID:n potentiaali reaaliaikaisessa henkilöpaikannusjärjestelmässä beach volley -kentällä
No full textElämme ajassa, jossa informaation määrä ja merkitys kasvaa valtavalla nopeudella. Dataanalytiikka kehittyy ja kerätyn datan arvo kasvaa jatkuvasti. Myös tiedonkeruumenetelmät
ja -tekniikat edistyvät, joten niiden luomia uusia mahdollisuuksia voitaisiin hyödyntää entistä laajemmin valmennuksen ja pelitaktisen analyysin tukena palloilulajeissa.
Tavoitteena oli tutkia passiivisen UHF RFID:n potentiaalia reaaliaikaisessa henkilöpaikannuksessa beach volley -kentän puoliskoa vastaavalla alueella. Tätä varten toteutettiin kohtuullisen laajat mittaukset JAMK:in pääkampuksen liikuntasalissa käyttäen ToP Tunniste
Oy:n lainaamaa neljän antennin RFID-laitteistoa. Mittauksissa kerättyä dataa käsiteltiin
Microsoft Excel-taulukkolaskentaohjelmalla havainnollisempaan ja tulkittavampaan muotoon. Sitten kehitettiin kolme erilaista laskentatapaa, joilla antennien mittaamien etäisyyksien pohjalta saadaan arvioitua kohteen sijainti mittausalueella. Näitä laskentatapoja vertailtiin toisiinsa staattisten tunnetuissa pisteissä olevien kohteiden paikantamisessa ja sovellettiin myös liikkuvan kohteen paikantamiseen.
Mittaustuloksista oli selvästi havaittavissa valitun tekniikan ja metodien riittämättömyys
erityisesti liikkuvan kohteen paikannukseen. Staattistenkin kohteiden paikantamisessa ilmeni epätarkkuutta ja paikoin suuriakin hajontoja. Neljällä tunnisteella varustettua staattista kohdehenkilöä paikannettaessa saavutettiin pienimmillään n. 2,56 metrin poikkeamakeskiarvo todellisesta sijainnista. Pelkkiä tunnisteita paikannettaessa päästiin n. 1,6 metrin
poikkeamakeskiarvoon, mutta sekin on 6 m * 6 m mittausalueella merkittävän suuri virhe.
Passiivinen UHF RFID ei tulosten perusteella ollut ainakaan tutkimushetkellä vielä valmis
pelaajien reaaliaikaiseen paikantamiseen beach volley -kentällä. Toivottavasti tulevaisuudessa tekniikan kehitys mahdollistaa tämänkin käyttötarkoituksen.We live in an era, where the amount of information and its significance is growing on a
huge pace. Data analysis evolves and the value of gathered data is increasing all the time.
The methods and technologies we use to gather the information are also improving and
enabling more use cases, like supporting the coaching and tactical analysis in ball games.
The objective was to study the potential of UHF RFID based real-time localization system
when locating individuals in an area comparable to a half of a beach volleyball court. To do
that, quite many measurements were done in the JAMK main campus gym using 4-antenna RFID-system lent by ToP Tunniste Oy. The data gathered in the measurements was
processed in Microsoft Excel to achieve more illustrative form. Then, three different ways
of approximating the position of the target based on the distance estimates from the antennas were developed. These three means were compared against each other in localizing static targets in known locations and later applied to locate a moving target.
From the results it is easy to point out the insufficiency of the chosen technology and
methods when it comes to localization of a target, especially when it is moving. Even locating the static targets was proven inaccurate and the deviation was very large at times.
When locating an individual with 4 tags as a static target, the best result was 2,56 meters
of average deviation from the actual location. With a floating target of 4 tags the best result was 1,6 meters of average deviation, but that is a very notable too in a 6 m * 6 m area
of measurement.
According to the results UHF RFID, at the time of the study took place was not ready for
real-time localization of the players on a beach volleyball court. Hopefully, technical advancements in the future will make this use case possible too
