Towards Active Course Marks for Autonomous Sailing Competitions

This paper describes the environmental monitoring / regatta beacon buoy under development at the Laboratory of Autonomous Systems (LSA) of the Polytechnic Institute of Porto. On the one hand, environmentalmonitoring of open water bodies in real or deferred time is essential to assess and make sensible decisions and, on the other hand, the broadcast in real time of position, water and wind related parameters allows autonomous boats to optimise their regatta performance. This proposal, rather than restraining the boats autonomy, fosters the development of intelligent behaviour by allowing the boats to focus on regatta strategy and tactics. The Nautical and Telemetric Application (NAUTA) buoy is a dual mode reconfigurable system that includes communications, control, data logging, sensing, storage and power subsystems. In environmental monitoring mode, the buoy gathers and stores data from several underwater and above water sensors and, in regatta mode, the buoy becomes an active course mark for the autonomous sailing boats in the vicinity. During a race, the buoy broadcasts its position, together with the wind and the water current local conditions, allowing autonomous boats to navigate towards and round the mark successfully. This project started with the specification of the requirements of the dual mode operation, followed by the design and building of the buoy structure. The research is currently focussed on the development of the modular, reconfigurable, open source-based control system. The NAUTA buoy is innovative, extensible and optimises the on board platform resources.

A maritimidade portuguesa : a extensão da plataforma continental

As potencialidades da plataforma continental estendida são enormes e variadas, desde as que podem ser obtidas através de sectores tradicionais – como portos e marinas ou turismo náutico – até as que advirão de novos sectores como a exploração dos fundos do mar ou a energia das ondas, entre outras. Com efeito, devido ao alargamento resultante das negociações nas Nações Unidas, é praticamente garantido que Portugal passe a controlar um espaço marítimo, acrescido de 2.1 milhões de km2, isto é, vinte vezes a extensão da sua superfície terrestre. A maritimidade de Portugal constitui um traço profundamente marcado na sua história, bem como nas suas tradicionais práticas económicas, sociais e simbólicas. Na verdade, os últimos anos testemunharam a criação de um amplo consenso quanto ao papel determinante que o desenvolvimento costeiro, a superfície e o comprimento dos limites do “Mar Português” terá no futuro do país. Da articulação entre o Território Nacional, o Oceano Atlântico e o Continente Europeu, associada à confluência das vias de comunicação marítimas que ligam a Europa à América do Norte e do Sul configurar-e-ão os aspectos essenciais do designado “Espaço Estratégico de Interesse Nacional Permanente”. A área geográfica prioritária para o desenvolvimento das acções militares de Defesa Nacional e dos interesses vitais permanentes inclui assim – para além do Território Nacional – o Espaço Interterritorial, o Mar Territorial (MT), o espaço aéreo sob responsabilidade nacional e a Zona Económica Exclusiva (ZEE). O País é titular de soberania no território continental e nos arquipélagos da Madeira dos Açores, para além de estar comprometido com alguns Estados da CPLP, que têm no Atlântico Sul uma importante e poderosa presença. Pela geografia e pela definição dos interesses dos Estados e dos grandes espaços em que estão incluídos, Portugal está na articulação da segurança do Atlântico Norte com a segurança do Atlântico Sul. Esta realidade acarreta novos desafios para a Defesa Nacional, assumindo como preocupações acrescidas o terrorismo, o tráfico e a pirataria marítimas, entre outras.

Yacht charter in Portugal- developing a business model for a sailing charter company

Given the signals that Portugal can be a great destination for charter sailing, the purpose of this work is to disprove this. Thereby the model of Porter’s five forces has been used to analyze the Portuguese yacht charter market, whereas a SWOT analysis should give an overview and compare the Portuguese market with the well running charter market of Croatia. The research outcome on the supply side as well as on the demand side should then serve as a foundation for establishing a model of a sailing charter company in Portugal, explained with the aid of the Canvas model.

Distribuição geográfica da fauna e flora da Baía de Guanabara

The author studied, the horizontal and vertical distribution of most common part of the flora and fauna of the bay of Guanabara at Rio de Janeiro. In this paper the eulittoral, poly, meso and oligohaline regions were localised and studied; and the first chart of its distribution was presented (fig. 2). The salinity of superficial waters was established through determinations based on 30 trips inside the buy for collecting biological materials. Some often 409 determinations which were previous reported together with the present ones served for the eleboration of a salinity map of the bay of Guanabara (fig. 1). This map of fig. 2 shows the geographic locations of the water regions. EULITTORAL WATER REGIME — Fig. 3 shows the diagram scheme of fauna and flora of this regime. Sea water salinity 34/1.000, density mean 1.027, transparent greenish waters, sea coast with moderate bursting waves. Limpid sea shore with white sand, gneiss with the big barnacle Tetraclita squamosa var. stalactifera (Lam. Pilsbry. Vertical distributions: barna¬cles layers with a green region in which are present the oyster Ostrea pa-rasitica L., the barnacles Tetraclita, Chthamalus, Balanus tintinnabulum var. tintinnabulum (L.) e var. antillensis Pilsbry in connection with several mollusca and the sea beatle Isopoda Lygia sp. Covered by water and exposed to air by the tidal ritms, there is a stratum of brown animals that is the layer of mussels Mytilus perna L., with others brown and chestnut animals : the Crustacea Pachygrapsus, the little crab Porcellana sp., the stone crab Me-nippe nodifrons Stimpson, the sea stars Echinaster brasiliensis (Mull. & Tr.), Astropecten sp. and the sea anemones Actinia sp. Underneath and never visible there is a subtidal region with green tubular algae of genus Codium and amidst its bunches the sea urchin Lycthchinus variegatus (Agass.) walks and more deeply there are numerous sand-dollars Encope emarginata (Leske). The microplancton of this regime is Ceratiumplancton. POLYHALINE WATER REGIMB — Water almost sea water, but directly influenced by continental lands, with rock salts dissolved and in suspension. Salinity: 33 to 32/1.000. This waters endure the actions of the popular nicknamed «water of the hill» (as the waters of mesohaline and oligohaline regimes), becoming suddenly reddish during several hours. That pheno¬menon returns several times in the year and come with great mortality of fishes. In these waters, according to Dr. J. G. FARIA there are species of Protozoa : Peridinea, the Glenoidinium trochoideum St., followed by its satellites which he thinks that they are able to secret toxical substances which can slaughter some species of fishes. In these «waters of the hill» was found a species of Copepoda the Charlesia darwini. In August 1946 the west shore of the Guanabara was plenty of killed fishes occupying a area of 8 feet large by 3 nautical miles of lenght. The enclosure for catching fishes in the rivers mouthes presents in these periods mass dead fishes. The phenomenon of «waters of the hill» appears with the first rains after a period of long dryness. MESOHALINE WATER REGIME — Fig. 4 shows the the diagramm scheme. Salt or brackish water from 30 to 17/1.000 salinity, sometimes until 10/1.000. Turbid waters with mud in suspension, chestnut, claveyous waters; shore dirty black mud without waving bursting; the waters are warmer and shorner than those of the polihaline regime. Mangrove shore with the mangrove trees : Rhizophora mangle L., Avicennia sp., Laguncularia sp., and the »cotton tree of sea» Hibiscus sp. Fauna: the great land crab «guaimú» Cardisoma guanhumi Latr., ashore in dry firm land. There is the real land crab Ucides cordatus (L.) in wetting mud and in neigh¬ bourhood of the burrows of the fiddler-crabs of genus Uca. On stones and in the roots of the Rhizophora inhabits the brightly colored mangrove-tree-crab («aratu» Portuguese nickname) Goniopsis cruentata (Latreille) and the sparingly the big oyster Ostrea rhizophorae Guild. Lower is the region of barnacles Balanus amphitrite var. communis Darwin and var. niveus Darwin; Balanus tintinnabulum var. tintinnabulum (L.) doesn't grow in this brackish water; lower is the region of Pelecipoda with prepollency of Venus and Cytherea shell-fishes and the Panopeus mud crab; there are the sea lettuce Ulva and the Gastreropod Cerithium. The Paguridae Clibanarius which lives in the empty shells of Gasteropod molluscs, and the sessile ascidians Tethium plicatum (Lesuer) appears in some seasons. In the bottom there is a black argillous mud where the «one landed shrimps» Alpheus sp. is hidden. OLIGOHALINE WATER REGIME — The salinity is lower than 10/1.000. average 8/1.000. There are no barnacles and no sea-beetles Isopods of genus Lygia; on the hay of the shore there are several graminea. This brackish water pervades by mouthes of rivers and penetrates until about 3 kilometers river above. While there is some salt dissolved in water, there are some mud crabs of the genus Uca, Sesarma, Metasesarma and Chasmagnatus. The presence of floating green plants coming from the rivers in the waters of a region indicated the oligohaline waters, with low salt content because when the average of NaCl increases above 8/1.000 these plants die and become rusty colored.

Relaciones ontogénicas y espacio-temporales en la dieta del calamar gigante (Dosidicus gigas) en Perú, utilizando un Modelo Aditivo Generalizado

El calamar gigante Dosidicus gigas (d'Orbigny, 1835) es un depredador importante en el ecosistema del Perú. Se postula que el papel del calamar gigante varía teniendo en cuenta la talla, tiempo, hora, temperatura y distribución espacial. Para comprobar esta hipótesis se aplicó un modelo aditivo generalizado (GAM) en datos biológicos de alimentación de 4178 calamares gigantes capturados por la flota industrial pesquera a lo largo del litoral peruano (3ºS a 18ºS) desde 2 a 299 millas náuticas (mn) de distancia a la costa desde el año 2004 a 2009 realizados por el Laboratorio de Ecología Trófica del Instituto del Mar del Perú (IMARPE). La talla de los calamares estudiados fluctuó entre 14 y 112 cm de longitud de manto (LM). En total 43 item-presa fueron registrados, los grupos más importantes fueron los cefalópodos (Dosidicus gigas), Teleosteii (Photichthyidae, Myctophidae y Nomeidae) y Malacostraca crustáceos (Euphausiidae). Las presas principales fueron D. gigas (indicando canibalismo) en términos gravimétricos (% W=35.4), los otros cephalopodos en frecuencia de ocurrencia (FO=14.4), y los eufáusidos en términos de abundancia relativa (% N=62.2). Estos resultados reflejan una alta variabilidad de la dieta, y un espectro trófico similar en comparación con otras latitudes en ambos hemisferios (México y Chile). Los modelos GAM muestran que todas las variables predictoras fueron significativas en relación a la variable respuesta llenura estomacal (p <0.0001). La llenura estomacal fue mayor en los individuos juveniles, también durante la noche hubo mayor consumo, mientras no se reflejaron tendencias en la alimentación con relación a la temperatura superficial del mar (TSM), pero espacialmente se observan cambios en la dieta, aumentando el porcentaje de llenura a medida que esta especie se aleja de la costa. Por lo tanto se concluye que la dieta del calamar gigante depende de la talla y su distribución espacio-temporal.

The relationship between fear of falling and foot clearance in older people

Introduction : Fear of falling (FOF) is associated with falls and modifications in gait parameters. Foot clearance during walking is directly linked to tripping and falling. The relationship between FOF and foot Downloaded from http://gerontologist.oxfordjournals.org/ at Université & EPFL Lausanne on January 23, 2013 436 The Gerontological Society of America clearance has never been evaluated. Methods : Participants (N=568, aged 66 to 71 years, 57.2% women) underwent gait parameters measurements using footworn sensors. Specific foot clearance parameters evaluated included maximal and minimal heel and toe clearances and their variability. FOF was assessed using a single question. Results : Overall, 27.4% of the participants reported FOF. Compared to the others, participants with FOF had decreased maximal heel (28.9 vs 30.4 cm, p<.001) and toe clearance (12.5 vs 13.8 cm, p<.001), and decreased minimal toe clearance variability (SD 3.7 vs 4.0 cm, p<.001). Conclusion : These preliminary results suggest a relationship between FOF and foot clearance parameters. Multivariate analyses are underway.

Variabilidad espacial de la pesquería de Dosidicus gigas (d’Orbigny, 1835) calamar gigante del 2004 al 2012

Se efectuó un análisis de la distribución espacial de operaciones de pesca de la flota calamarera industrial dentro y fuera de la zona económica exclusiva peruana (ZEE) con relación a la temperatura superficial de mar (TSM) y concentración de clorofila-a (Cl-a) para el periodo 2004-2012. La data de operaciones de pesca se dividió en tres periodos en función a distancia a la costa considerando regulaciones de pesca, de enero 2004 a octubre 2010, de noviembre 2010 a diciembre 2011 y 2012. Durante el primer periodo, se identificaron dos patrones mensuales de distribución espacial, de enero a julio fue a lo largo del litoral desde Paita (5°S) hasta San Juan de Marcona (15°22’S) y de agosto a diciembre entre Chimbote y Paita. En el segundo periodo, las operaciones de pesca formaron pequeñas concentraciones y puntos de pesca dispersas debido a la restricción de pesca dentro de las 80 millas náuticas desde noviembre del 2010. Durante el 2012 la flota se localizó fuera de la ZEE. Las mayores concentraciones de la flota se ubicaron entre 30 a 90 millas náuticas de la costa. Mayores concentraciones de pesca se localizaron en Paita-Chimbote (5°-9°S) y Callao- San Juan de Marcona (12°03’-15°22’S). Las faenas de pesca se realizaron en un rango amplio de TSM entre 14,1 y 26,8 °C, con mayor incidencia en temperaturas entre 18,4 a 22 °C, con tendencia a localizarse en áreas de mayor temperatura durante los últimos años. Respecto a la clorofila-a, la flota faenó entre concentraciones de clorofila-a de 0 a 9,5 mg/m3 dentro de la ZEE, y entre 0,2 y 0,5 mg/m3 fuera de la ZEE. Se observó un patrón de distribución de flota, asociado a las anomalías de temperatura superficial de mar del área El Niño 1+2, a la distribución latitudinal y una variabilidad cíclica mensual de la TSM.

Role of glast-positive glial cells during photoreceptor development

Purpose: Taking advantage of two transgenic lines, glast.DsRed and crx.gfp, that express fluorescent proteins in glial and photoreceptor cells respectively, we investigate the role of glast-positive glial cells (GPCs) in the survival/differentiation/proliferation of age-matched photoreceptor cells. Methods: Primary retinal cells were isolated from newborn transgenic mouse retina (glast.dsRed::crx.gfp) at postnatal day (P0/P1) and propagated in defined medium containing epidermal growth factor (EGF) and fibroblast growth factor 2 (bFGF). By flow-sorting another population of pure GPCs was isolated. Both populations were expanded and analyzed for the presence of specific retinal cell markers. Notably, the primary cell culture collected from the transgenic line glast.dsRed::crx.gfp showed a conspicuous presence of immature photoreceptors growing on top of GPCs. In order to reveal the role of such cells in the survival/differentiation/proliferation of photoreceptors we set up in vitro cultures of retina-derived cells that allowed long-term time-lapse recordings charting every cell division, death and differentiation event. To assess the regenerative potential of GPCs we challenged them with compounds mimicking retinal degeneration (NMU, NMDA, Zaprinast). Mass spectrometry (MS), immunostainings and other molecular approaches were performed to reveal adhesion molecules involved in the relationship between glial cells and photoreceptors. Results: Both primary cell lines were highly homogenous, with an elongated morphology and the majority expressed Müller glia markers (MG) such as glast, blbp, glt-1, vimentin, glutamine synthetase (GS), GFAP, cd44, mash1 and markers of reactive Müller glia such as nestin, pax6. Conversely, none of them were found positive for retinal neuron markers like tuj1, otx2, recoverin. Primary cultures of GPCs show the incapability of glial cells to give rise to photoreceptors in both wild type or degenerative environment. Furthermore, primary cultures of pure GPCs challenged with different compounds did not highlight the production of new glial cell-derived photoreceptors. Adhesion molecules involved in the contact between photoreceptors and glial cells are still under investigation. Conclusions: Primary glia cells do not give rise to photoreceptor cells in wt and degenerative conditions at least in vitro. The roles of glial cells seem to be more linked to the maintenance/proliferation of photoreceptor cells.

Emergency Department Use by oldest-old Patients Between 2005 And 2010 in a Swiss University Hospital

Introduction: Population ageing challenges Emergency Departments (ED) with a population shift toward higher age groups. Patients aged 85+, represent the fastest growing segment, leading to more prevalent complex situations within ED. Method: Retrospective analysis of 56'162 ED visits of patients at the University of Lausanne Medical Center (CHUV), from 2005 to 2010. Results: ED visits of 65+ patients increased from 8'228 to 10'390/year, representing 6 patients/day more (+26%). 85+ Patients increased by +46% vs +20% for the 65-84 (+20% ED visits of people 18-64y). Median age of the 65+ ED patients increased from 78.7 to 79.3 years. 85+ patients were more likely than 65-84y patients to come from a NH setting (13% vs 4%) and to be hospitalised (70% vs 59%). Median length of stay difference between both age groups extended from 2 hours 08 min in 2005 to 2 hours 45 min in 2010. First reason to visit ED was fall/injury for 85+ patients (27%; 65-84: 18%) and a cardiovascular disorder for patients aged 65-84y (18%; 85+: 16%). Part of high degree of emergency cases (42%) and readmission to ED within 30 days (8%) were similar for both age classes (similar proportions in 2005 and 2010 for these 3 issues). Conclusion: Patients aged 85+ are the fastest growing group admitted to ED. Compared to younger counterparts, they use more ED ressources and the differences are increaseing overtime. ED addressing specific needs of geriatric patients would improve their care and lead to a better use of available resources.

Climate Change Impacts on Iowa, 2010, January 1, 2011

Today, perhaps without their realization, Iowans are factoring climate change into their lives and activities. Current farming practices and flood mitigation efforts, for example, are reflecting warmer winters, longer growing seasons, warmer nights, higher dew-point temperatures, increased humidity, greater annual stream flows, and more frequent severe precipitation events (Fig. 1) than were prevalent during the past 50 years. Some of the effects of these changes (such as longer growing season) may be positive, while others (particularly the tendency for greater precipitation events that lead to flooding) are negative. Climate change embodies all of these results and many more in a complex manner. The Iowa legislature has been proactive in seeking advice about climate change and its impacts on our state. In 2007, Governor Culver and the Iowa General Assembly enacted Senate File 485 and House File 2571 to create the Iowa Climate Change Advisory Council (ICCAC). ICCAC members reported an emissions inventory and a forecast for Iowa’s greenhouse gases (GHGs), policy options for reducing Iowa’s GHG, and two scenarios charting GHG reductions of 50% and 90% by 2050 from a baseline of 2005. Following issuance of the final report in December 2008, the General Assembly enacted a new bill in 2009 (Sec. 27, Section 473.7, Code 2009 amended) that set in motion a review of climate change impacts and policies in Iowa. This report is the result of that 2009 bill. It continues the dialogue between Iowa’s stakeholders, scientific community, and the state legislature that was begun with these earlier reports.

Iowa Plan for Energy Independence, 2007

Iowa’s first annual Energy Independence Plan kicks off a new era of state leadership in energy transformation. Supported by Governor Chet Culver, Lieutenant Governor Patty Judge, and the General Assembly, the Office of Energy Independence was established in 2007 to coordinate state activities for energy independence. The commitment of the state to lead by example creates opportunities for state government to move boldly to achieve its goals, track its progress, measure the results, and report the findings. In moving to energy independence, the active engagement of every Iowan will be sought as the state works in partnership with others in achieving the goals. While leading ongoing efforts within the state, Iowa can also show the nation how to effectively address the critical, complex challenges of shifting to a secure energy future of affordable energy, cost-effective efficiency, reliance on sustainable energy, and enhanced natural resources and environment. In accordance with House File 918, “the plan shall provide cost effective options and strategies for reducing the state’s consumption of energy, dependence on foreign sources of energy, use of fossil fuels, and greenhouse gas emissions. The options and strategies developed in the plan shall provide for achieving energy independence from foreign sources of energy by the year 2025.” Energy independence is a term which means different things to different people. We use the term to mean that we are charting our own course in the emerging energy economy. Iowa can chart its own course by taking advantage of its resources: a well-educated population and an abundance of natural resources, including rich soil, abundant surface and underground water, and consistent wind patterns. Charting our own course also includes further developing our in-state industry, capturing renewable energy, and working toward improved energy efficiency. Charting our own course will allow Iowa to manage its economic destiny while protecting our environment, while creating new, “green collar” industries in every corner of Iowa. Today Iowa is in a remarkable position to capitalize on the current situation globally and at home. Energy drives the economy and has impacts on the environment, undeniable links that are integral for energy security and independence. With the resources available within the state, the combination of significant global changes in energy and research leading to new technologies that continue to drive down the costs of sustainable energy, Iowa can take bold strides toward the goal of energy independence by 2025. The Office of Energy Independence, with able assistance from hundreds of individuals, organizations, agencies, and advisors, presents its plan for Iowa’s Energy Independence.

Muovituotteen markkinakartoitus ja markkinoinninsuunnittelu

Oy Finnpak Ab haluaa parantaa valumuovituoteryhmänsä markkina-tuntemusta ja kartoittaa potentiaaliset asiakkaansa Suomen ja Ruotsin markkinoilla. Diplomityön tavoitteena on selvittää edellä olevat asiat, sekä tarkastella yrityksen nykytilaa ja miettiä, mitä kehittämistä yrityksen nykyisessä markkinoinnissa on. Saatujen tietojen perusteella muodos-tetaan toimintorunko, markkinointisuunnitelma, jota käytetään hyväksi lähivuosien liiketoimintastrategioiden suunnittelussa.Potentiaalisista asiakkaista saadut tiedot perustuvat kyselytutkimukseen. Tutkimus suoritettiin soittamalla ensin valitun teollisuussektorin yrityksiin ja kohdeyrityksille lähetettiin tutkimuslomake.Työssä saatujen tulosten mukaan sekä sisäisessä että ulkoisessa markkinoinnissa on huomattavasti parantamisen varaa. Tärkein työssä esiin tullut uudistus valumuovipuolella oli tuotekehityksen maksullistaminen. Ylivoimaisesti suurin työssä esiin tullut projekti on kuitenkin yritysnimen yhtäläistäminen nykyisen tuotenimen kanssa. Yrityksen nimi on tarkoitus uudistaa vuoteen 2003 mennessä, joka on yrityksen neljäskymmenes toimintavuosi.

Procurement and inventory management in product ramp down

Tuotteiden elinkaaret elektroniikkateollisuudessa ovat lyhentyneet entisestään. Paineet uusien kehittyneempien tuotteiden lanseeraamiselle ovat kasvaneet. Huonosti hoidettu tuotevaihto voi aiheuttaa merkittäviä kustannuksia yritykselle mikäli alasajon kustannusvaikutusta tulokseen aliarvioidaan. Työ käsittelee markkinoilta poistuvan tuotteen materiaalivirtojen hallintaa tuotevaihdon aikana. Lähtökohtana työssä oli kehittää toimintatapa miten tuotteen alasajon aikana tulisi toimia sekä mallintaa hankintaketju riskien ja pullonkaulojen löytämiseksi. Päätavoitteena oli materiaalivaraston arvon minimoiminen sekä ylijäämämateriaalien hyödyntäminen. Työn merkittävimpiä tuloksia oli hankintaketjun materiaalivirtojen seurantaan kehitetty Excel työkalu sekä alasajon liittyvien työvaiheiden kuvaaminen.
