Fitness, Flexibility, and Suspension: An Aquatics Facility on Washington, D.C.'s Southwest Waterfront

Biesiadny-Mrstik, Michelle Marie 02 July 2004 (has links)
To create a legible building, the structure's form must describe and reinforce the mission of the organization that inhabits it. This proposal for a regional competition, training and recreational aquatics facility demonstrates ideas of physical fitness through an exploration of muscles, cables, tension, joints, and bones. The building is part of a larger urban strategy for redeveloping the Washington Channel waterfront in Southwest Washington, D.C. Early images of transformed beach glass, thread, and basswood generated the inspiration for the basic architectural components: the wall, the columns, and the suspended jewels. The following document gives definition to the basic elements. / Master of Architecture

A Domain-Specific Language for Aviation Domain Interoperability

Comitz, Paul H 01 January 2013 (has links)
Modern information systems require a flexible, scalable, and upgradeable infrastructure that allows communication and collaboration between heterogeneous information processing and computing environments. Aviation systems from different organizations often use differing representations and distribution policies for the same data and messages, limiting interoperability and collaboration. Although this problem is conceptually straightforward, information exchange is error prone, often dramatically underestimated, and unexpectedly complex. In the air traffic domain, complexity is often the result of the many different uncoordinated information processing environments that are used. The complexity and variation in information processing environments results in a barrier between domain practitioners and the engineers that build the information systems. These divisions have contributed to development challenges on high profile systems such as the FAA's Advanced Automation System and the FBI's Virtual Case File. Operationally, difficulties in sharing information have contributed to significant coordination challenges between organizations. These coordination problems are evident in events such as the response to Hurricane Katrina, the October 2009 Northwest Airlines flight that overflew its scheduled destination by more than 100 miles, and other incidents requiring coordination between multiple organizations. To address interoperability in the aviation domain, a prototype Domain-Specific Language (DSL) for aviation data, an aviation metadata repository, and a data generation capability was designed and implemented. These elements provide the capability to specify and generate data for use in the aviation domain. The DSL was designed to allow the domain practitioner to participate in dynamic information exchange without being burdened by the complexities of information technology and organizational policy. The DSL provides the capability to specify and generate information system usable representations of aviation data. Data is generated according to the representational details stored in the aviation metadata repository. The combination of DSL, aviation metadata repository, and data generation provide the capability for aviation systems to interoperate, enabling collaboration, information sharing, and coordination.

Sound Characteristics of the Large Yellow Croaker, Larimichthys crocea and Phylogeny of the Western Pacific Sciaenid Genera Inferred by Molecular Evidence

Lo, Pei-chun 13 July 2011 (has links)
The fishes of the family Sciaenidae have been known to vocalize during the reproductive season, and it is known that in most species only the male calls. Sounds are produced by vibration of the sonic muscles, which set the swim bladder into resonance. In addition, they also emit sounds by the same mechanism while being disturbed. The large yellow croaker, Larimichthys crocea (Perciformes, Sciaenidae) is one of the important commercial fish species distributed in South China Sea, East China Sea and southern Yellow Sea. In the past years, they have been overfished because of their high fishery value. Many aquatic farms started to culture economically important sciaenids because of the established artificial propagation technique. Now large yellow croakers have been successfully cultured in Fuchien Province, China. Unlike most sciaenids, the sonic muscles are only possessed by male, both male and female large yellow croakers have sonic muscles. This species provides the best opportunity to investigate the characteristics of sounds produced by different genders. The aims of this study were 1) to describe the hand-held disturbance sounds in large yellow croakers, 2) to describe the sounds produced during courtship and spawning in large yellow croakers being injected hormone (LHRH-A3), 3) to investigate the phylogenetic position of large yellow croaker in relation to other sciaenid fishes, and 4) to understand the evolutionary path of swim bladder morphology in the family Sciaenidae. The results show that 1) the pulse numbers of hand-held disturbance sounds in large yellow croaker can reach 23; 2) The reproductive sounds consisted of 1 to 7 pulses which started at about 1400 hr, and both vocal activity (no. sounds/min) and pulse numbers per call would increase with time. However, spawning occupied at the time slot when pulse numbers per call reached 7 in the unisex pond. The sounds in the ponds with only males or females can only recorded the sounds with 1 to 2 pulses; 3) The genus Collichthys was the sister taxon of large yellow croaker. Morphology of the swim bladder in Collichthys is similar to large yellow croaker; 4) Morphology of swim bladder evolved from simple to complex forms. Finally, Larimichthys, Collichthys, and other sciaenid genera distributed in the Indo-western Pacific Ocean including Miichthys, Boesemania, Bahaba, Panna, Atrobucca, Otolithes, Pterotolithus, Chrysochir, Paranebris, Protonibea, Pennahia, Nibea, Dendrophysa and Johnius form a monophyletic group with a bootstrap value of 100. Most of the members have the complex swim bladders with many appendages except Boesemania, Bahaba and Paranebris. Presence of simple form of the swim bladder in these three genera is inferred as a result of morphological reversal.

The swim bladder of Glaucosoma buergeri (Perciformes: Glaucosomatidae) and the histological and biochemical characteristic of its associated muscles

Wu, Kuo-Chang 12 August 2005 (has links)
The swim bladder of Glaucosoma hebracium is specialized by having two side membranes extending dorsally from the side to the vertebrae. This characteristic supports the morphology of the Glaucosomatidae. There is a pair of reddish muscles connecting the skull and the swim bladder of the Glaucosoma hebracium. This type of muscle is likely to involve with sound production. However, vocalization has not been reported in the Glaucosomatids. As direct recordings for sound production in live specimens of this species could not easily be carried out, function of these swim bladder muscles was assessed by means of biochemical assay. Activities of Citrate synthase (CS) and L-lactate dehydrogenase (LDH), known to involve with energy supply during muscle contraction were assessed. Two-dimensional gels for the white muscle, tail region red muscle and swim bladder muscles were compared to reveal difference of protein expression. Results show that CS activity of the swim bladder muscle was higher than the white muscle. But LDH activities in these two types of muscles were not significant different. As high activities in CS reflecting aerobic nature of the tissue, the present dataset suggests that the swim bladder muscles should involve with sound production. Proteomics analyzes identified 14 proteins from the swim bladder muscle, one of them are related to energy production (ATP synthase beta chain). Two-dimensional gels show some different spots from these three type muscles. These results help us to find some different proteins in these three types of muscles of this fish. In conclusions base on these evidence in morphology, histology, enzyme activity assay and two-dimensional gels, the swim bladder muscles should involve with sound production in G. hebracium.

Erhöhung der Antriebsleistungen beim Startsprung im Sportschwimmen

Graumnitz, Jens 29 August 2011 (has links) (PDF)
Die vorliegende Arbeit soll den Nachweis erbringen, dass mit einem spezifi-schen Trainingsprogramm, welches aus einer Kombination von Techniktrai-ningsformen besteht, Teilkörperbewegungen beim Absprung vom Block so op-timiert werden, dass quantifizierbare Verbesserungen im Startabschnitt erzielt werden können. Ausgangspunkt ist die auf Wettkampfanalysen und Leistungsdiagnosemaßnahmen basierende Annahme, dass bei der Mehrheit der deutschen Nationalmannschaftsschwimmer erhebliche Reserven in der Ausführung der Absprungbewegung vom Block bestehen. Die Folge sind Nachteile der deutschen Sportler im Startabschnitt gegenüber der internationalen Konkurrenz. Ein spezielles Techniktrainingsprogramm wird als Trainingsintervention in einer Nachwuchstrainingsgruppe erprobt. Die Intervention erstreckt sich über zehn Wochen. Während der ersten sechs Wochen wird in wöchentlich vier Teiltrainingseinheiten ein Programm zur Sensibilisierung der Teilköperbewegungen absolviert. In weiteren vier Wochen erfolgt wöchentlich einmal ein Messplatztraining. Neun Wochen nach Abschluss des ersten Interventionszeitraumes wird die Intervention wiederholt. Im Vergleich mit einer Kontrollgruppe können über das gesamte Trainingsjahr 2007/2008 für die Interventionsgruppe größere Entwicklungsraten bei den Startleistungsmerkmalen nachgewiesen werden. Die gewonnenen Erkenntnisse unterstreichen die Notwendigkeit eines sorgfältig geplanten und kontinuierlich durchgeführten Techniktrainings zur Verbesserung der azyklischen Absprungbewegung vom Block ohne, dass die Entwicklung an-derer Leistungsvoraussetzungen beschränkt wird.

Sezónní pravděpodobnostní hydrologické předpovědi / Seasonal probabilistic hydrological forecasting

Šípek, Václav January 2014 (has links)
Seasonal hydrological forecasts represent a very current topic, especially in the context of extreme hydrological events that have taken place at the end of the 20th and beginning of the 21st century. These events are represented by large scale floods and long lasting periods of drought. This has led to a need for the effective water management strategies. These management strategies have to be able to efficiently distribute water resources both in the space and time. Seasonal hydrological forecasting systems constitute an essential part of water management strategies, as they enable the runoff estimation in a sufficient advance. This thesis deals with the seasonal hydrological forecasting system with a one month lead. The aim of this study is to apply three forecasting methods using an experimental watershed in the Czech Republic. The first method is represented by the reference climatology approach, the latter by the well-tested Ensemble Streamflow Prediction system (ESP), and the last by its newly proposed modification. This modification (modified ESP - mESP) is based on the restriction of input data established on their relations to the large scale climatological variables and patters. The first part of the thesis is focused on the investigation of possible relations among hydrometeorological...

A Comparison of Three Breaststroke Turns and Their Effects on Swimming Fifty Yards

Courtway, Robert Franklin, 1927- 05 1900 (has links)
The problem with which this study was concerned was that of comparing three methods of executing the competitive breaststroke turn and their effects on swimming fifty yards. The turns utilized were the AAU, NCAA, and somersault. A related purpose was that of analyzing the time a breaststroke competitor was to be submerged on the glide following the turn. One hundred four male, senior swimmers from teams in the Arkansas AAU were rated on five components of the breaststroke. Twenty-nine advanced and thirty novice breaststrokers were selected from this group to participate in this study. The subjects were timed for a distance of fifty yards using, in order, the AAU, NCAA, and somersault turns.

Morphology of otolith, swim bladder, and phylogenetic relationships of acropomatids (Perciformes: Acropomatidae)

Huang, Yin-Hsiang 31 August 2010 (has links)
Basioccipital foramen (bof) is found in four acropomatid species, including Apogonops anomalus, Doederleinia berycoides, Neoscombrops annectens, and Synagrops japonicus belonging to four genera. This structure is just near the fish¡¦s inner ear and to which the anterior diverticulae of the swim bladder in the species protrudes. This configuration is though to be closely related to enhance hearing capabilities and an important synapomorphic system to the phylogeny of acropomatids. The structural parameters of the sagittae (i.e., otolith area, otolith sulcus area, ratio of sulcus to area, otolith weight, hair cell density in otolithic macula, and the stereocilia number per hair cell bundle) were estimated, measured, and analyzed. The data of the parameters from the ¡¥bof-possessing¡¦ acropomatids are lower than that of the ¡¥non-bof¡¦ acropomatids. These values infer a probable poorer auditory capability of the ¡¥bof-possessing¡¦ acropomatids. COI, cytochrome b, and rhodopsin sequences of 12 species in five acropomatid genera (i.e., Acropoma, Doederleinia, Malakichthys, Neoscombrops, Synagrops) were analyzed to resolve the issue whether the configuration between ¡¥bof¡¦ and anterior diverticulae of swim bladder representing synapomorphic characters. The constructed Bayesian and maximum parsimony trees indicate that the ¡¥bof-possessing¡¦ acrpomatids do not form a clade. These results suggest that thses specialized structures (¡¥bof¡¦ and anterior swim bladder diverticulae) have developed more than once in Acropomatidae (i.e., a case of convergence).

Improvements for Waran-patients in Finspång / Förbättringsarbete för Waran-patienter i Finspång

Lennartsson, Emma January 2014 (has links)
Närsjukvården i Finspång har idag 540 patienter som är i behov av, och behandlas med det blodförtunnande läkemedlet Waran. Läkemedlet ges till de som drabbats av blodpropp (bentrombos/lungemboli), förmaksflimmer eller har klaffproteser. Patienterna besöker i stor del den mottagning som finns på Finspångs Lasarett men det finns de som av olika anledningar inte kan ta sig till mottagningen, främst beroende på att de lider av andra sjukdomar som gör att de har svårt att förflytta sig längre sträckor. Därför besöks de i hemmet och där tar DS de prover som behövs. Grunden till projektet Närsjukvården i Finspång-Förbättringsarbete för Waran-patienter i Finspång, är att hitta andra lösningar på hur situation kan förändras och därigenom också förbättras för de patienter där provtagningen måste ske i hemmet. Projektet har resulterat i en analys kring fyra olika scenarier som alla medförde förbättringar både vad gäller kostnader, transporter och tid. För att få en inblick i vilka scenarier som användes beskrivs de nedan. Scenario 1a visar en bild över situationen som den såg ut när fösta kartläggningen skedde i och med det första besöket på Närsjukvården i Finspång. Scenario 1b visar en bild över hur hanteringen av patienterna fungerar vid andra kartläggningen på Närsjukvården i Finspång. Här har vissa patientbesök redan ersatts med att patienterna själva, med hjälp av CoaguChek, genomför kontroll av sitt INR-värde. Scenario 2 liknar scenario 1a men istället för en distriktssköterska (DS) är det en biomedicinsk analytiker (BMA) som besöker patienterna och genomför provtagningen. Scenario 3 ger en bild över hur det ser ut när det är en DS som gör hembesöken men att provtagningen nu sker med hjälp av CoaguChek. Scenarier har därefter analyserats sinsemellan med fördelar och nackdelar och projektet har kommit fram till den lösning som projektet anser vara den bäst lämpade för hanteringen av Waran patienterna.
