Forecasting the Inland Empire's Economic Recovery

Franklin, Jesse C. 01 January 2010 (has links)
The Inland Empire -Riverside and San Bernardino Counties - was one of the hardest hit areas in all of the United States during the Great Recession. Home prices have declined over 50%, significantly more than the 25% decline in the surrounding Los Angeles County, and housing starts have declined to over 90% from 2005. The Inland Empire has one of the highest unemployment rates in the US at 14.8%. This paper attempts to forecast the recovery for the Inland Empire. Employing univariate forecasts along with VAR(12) forecasts, focusing on housing starts and unemployment rates as the underlying variables, we find that there is little hope for a recovery over the next 3 years. The model predicts unemployment to either rise even more or, at best, remain stagnant. Housing starts are predicted to remain constant over the next three years.

Swimming in four goldfish (Carassius auratus) morphotypes: understanding functional design and performance through artificial selection

Li, Jason 05 1900 (has links)
Although artificially selected goldfish exhibit swimming performance decrements, with the most derived morphotypes more affected, they can be utilized to explore functional design and movement pattern principles in aquatic vertebrates. Drag, steady swimming kinematics (tailbeat frequency, amplitude, stride length), energetics (standard and active metabolic rate), fast-start performance (average and maximum velocity and acceleration), stability in yaw and roll and propulsive muscle ultrastructural characteristics (mitochondrial volume density and spacing, myofibril diameter and capillary to fibre ratio in red and white muscle) were measured for four morphotypes: common, comet, fantail and eggfish, of comparable length (≈ 5 cm). A performance “pairing” (common and comet; fantail and eggfish) was a recurrent theme for most performance parameters. Vertebral numbers (30), segment lengths (≈ 0.85 mm) and standard metabolic rates (≈ 140 mg O2 kg-1 hr-1) are exceptions where values are the same. Fantail and eggfish drag and drag coefficients (referenced to frontally projected area ≈ 0.6 - 0.9) were higher (requiring more thrust at any given velocity) than those for the more streamlined common and comet (≈ 0.3 - 0.6; P < 0.05). This is reflected in kinematics; tailbeat frequency and stride length at any given velocity for the common and comet are lower and higher respectively than that of the fantail and eggfish (P < 0.05). Common and comet fatigue times are not significantly different from that of their ancestor, Crucian carp (P > 0.05), and are lower than those of the fantail and eggfish (P < 0.05). The cost of transport of the common and comet (≈ 0.6 mg O2 kg-1 m-1) is accurately predicted from the mass scaling relationship for fish (P > 0.05), but values for the fantail and eggfish (≈ 1.3 mg O2 kg-1 m-1) are not (P < 0.05). Eggfish steady swimming (dorsal fin absent) was characterized by rolling and yawing motions associated with significant energy losses. Common and comet fast-start performance (average velocity ≈ 0.45 m s-1, maximum velocity ≈ 1.2 m s-1, average acceleration ≈ 7.5 m s-2, maximum acceleration ≈ 35 m s-2) was similar to that of other locomotor generalists (e.g. trout). Eggfish maximum acceleration (≈ 5 m s-2) is poor due to the absence of inertial and lifting contributions to thrust from the dorsal fin and energy wasting rolling motions. Artificially selected fish can bear upon fitness related adaptations associated with form and movement, providing insights into the “performance envelope” of natural systems subject to ecological speciation.

No. of bitstreams: 1 Marcel Hubert Dissertacao.pdf: 1313483 bytes, checksum: ad53bacae4de2359a042c168a30c1940 (MD5) Previous issue date: 2005-08-09 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / It aimed to determine a procedure to evaluate the swimming starts through biomechanical methods. For this descriptive and exploratory study one analyzed the starts of 4 s tate andnational level swimmers, members of the swimming team from Doze de Agosto Club (Florianópolis, SC). Data were collected in the swimming pool of Doze de Agosto Club and treated in the Aquatic Biomechanics Research Laboratory of Santa Catarina State University. An underwater force plate was used. The force plate was fixed as a starting block in the opposite side of the original blocks. Two video cameras placed outside and inside the water were used in order to provide a lateral view of the starting block and of the swimming pool up to 15m (according to swimming rules it is the maximum distance for the swimmer to be completely submerged after the start). Light-emitting diodes were placed in the image field of the video cameras and connected to a signal synchronizer. Starting procedures conformed to the swimming rules of an official Freestyle event. Data were post-processed by SAD 32 System. For kinematic data InterVideo WinProducer 3 e CorelDraw&#63194; software were used. Descriptive statistics was used to characterize data and Pearson s correlation was used to verify the relationship between the variables and the start performance (&#945;=0,05). One verified there is a relationship between the variables angle of entry, flight distance and time in 5m and the start performance in the three different measured distances (10m, 15m and distance of the beginning of the stroke); the vertical force peak and the time in 10m were correlated to the performance measured in 15m and in the beginning of the stroke; the horizontal force peak, the resultant force, the takeoff angle, the distance of the beginning of the stroke and time of the underwater phase were only correlated to the time of the beginning of the stroke; there was a relationship between the block time and the time in 15m; there was also a relationship between the time of the beginning of the stroke and the time in 10m. The flight time was the only variable that did not present any correlation to the performance. One verified that the most adequate distance to evaluate the start performance was 10m; and three executions were enough to analyze the start variables. / Esta pesquisa teve como objetivo determinar um procedimento para se realizar avaliações das saídas na natação, através de medições biomecânicas.Participaram deste estudo 4 nadadores de níveis estadual e nacional, integrantes da equipe de natação do Clube Doze de Agosto, Florianópolis, SC. Os dados foram coletados na piscina do clube Doze de Agosto e tratados no Laboratório de Biomecânica Aquática do Centro de Educação Física, Fisioterapia e Desportos - CEFID/UDESC. Para a coleta de dados foi utilizada uma plataforma de força subaquática fixada sobre um suporte simulando o bloco de partida, posicionada na borda contrária a dos blocos da piscina. Simultaneamente, foram utilizadas duas câmeras de vídeo posicionadas dentro e fora da piscina, de forma que proporcionassem uma visão lateral e superior do bloco de partida e da piscina, até uma distância de 15m (distância máxima permitida pelas regras para que o nadador permaneça submerso). Um emissor de sinal luminoso (LED) ligado a um sincronizador de sinais foi enquadrado no campo de imagem de todas as câmeras e o sinal de partida foi dado seguindo procedimentos oficiais de partida de uma prova de nado Livre. Os dados obtidos por dinamometria foram pós-processados pelo sistema SAD-32. Para a cinemetria foram utilizados os softwares de edição de imagens InterVideo WinProducer 3 e CorelDRAW&#63194;. Para a caracterização dos dados foi utilizada a estatística descritiva e para a verificação da relação entre as variáveis e a performance foi utilizada a correlação de Pearson (&#945;=0,05). Verificou-se que as variáveis: ângulo de entrada, distância de vôo e tempo em 5 m têm relação com a performance na saída nas três distâncias testadas, já as variáveis pico máximo de força vertical e tempo em 10 m têm relação com a performance apenas nas distâncias de 15 m e de início do nado. As variáveis: pico máximo de força horizontal, força resultante, ângulo de saída, distância de início de nado e tempo submerso têm relação somente com o tempo de início de nado. O tempo de bloco tem relação com o tempo em 15 m e o tempo de início de nado com o tempo em 10 m. Das variáveis testadas somente para o tempo de vôo não foi encontrada correlação. A distância determinada como mais adequada para obtenção do tempo de performance foi 10 metros. O número mínimo e suficiente de execuções encontrado para analise das saídas foi de três.

AOT kompilering för minskad starttid av Java-baserade tjänster / AOT compilation to reduce startup time for Java-based services

Pergler, Oscar January 2023 (has links)
Software engineering architectures, such as microservices and serverless, have been increasingly adopted for their ability to address architectural challenges through a modular approach. This modularity involves isolating components and assigning them specific responsibilities independently of other components. Java, a computationally robust language, is frequently utilized in microservice architectures; however, the Java Virtual Machine (JVM) is often criticized for its slow and unpredictable startup times in these environments. This study investigates the startup time, response time, and CPU load of Java services compiled with either the JVM or GraalVM. A microservice system comprising three testable Java services was developed and monitored to identify any differences in the aforementioned metrics. The results indicate that GraalVM outperforms the JVM in terms of startup time. However, the impact of GraalVM on response time is not statistically significant enough to reject the null hypothesis. Additionally, GraalVM demonstrates lower CPU usage during cold starts. From an environmental perspective it is important to note that the shortened start time potentially comes at the cost of an increased development time depending on the complexity of the system and the seniority of the developer. / <p>Det finns övrigt digitalt material (t.ex. film-, bild- eller ljudfiler) eller modeller/artefakter tillhörande examensarbetet som ska skickas till arkivet.</p><p>There are other digital material (eg film, image or audio files) or models/artifacts that belongs to the thesis and need to be archived.</p>

Visualisering av tidssynkroniseradekraftdata vid sprintstarter på en mobilenhet / Visualization of time synchronizedforce data at sprint starts on a mobiledevice

Mayta Lavalle, Ricardo, Ernst, Reutergårdh January 2022 (has links)
Tillämpning av instrument vid utövande av explosiva idrottsgrenar, för att mäta en atlets kraftproduktion, kan användas vid analys för att fastställa hur bra en atlet presterar. Dessa typer av instrument finns på marknaden och är oftast tillämpade för sprintstarter och har funktionen att man kanfånga en atlet på film och koppla en händelse till det data som hämtats in via instrumentet. Nackdelenmed dessa system är att de antingen är väldigt dyra eller är i avsaknaden av att vara smidiga ochportabla då de oftast levereras med mycket kringutrustning.Syftet med detta examensarbete var att utveckla ett system bestående av en mobilapplikation, samtlogik till en mikrokontroll som registrerar den horisontella kraften vid sprintstarter från en analogkälla. Insamlade data beräknas och skickas sedan med hjälp av BLE-kommunikation till mobilapplikationen som presenterar kraftdata för användaren.Utöver detta var syftet även att få inhämtad kraftdata tidssynkroniserad mot en mobil enhet för attgöra det möjligt att utvärdera händelser mot externa källor som IMU och höghastighetsfilm.Resultatet av arbetet visar att det är möjligt att hämta samplade kraftdata från en mikrokontroll viaBLE-kommunikation. Det går även att presentera beräknade kraftdata visuellt för en slutanvändaremed en mobilapplikation och få händelserna tidssynkroniserade med hjälp av tidssynkroniseringsalgoritmer. Resultaten kan emellertid förbättras genom fortsatt utveckling av detta system. / The application of instruments in the practice of explosive sports, to measure an athlete's force production, can be used to determine how well an athlete performs. Present instruments on the marketare most often applied to sprint starts and function to capture an athlete on film, and link the eventto the data retrieved from the instrument. The disadvantages with present day systems are that theyare either too expensive or lack flexibility and portability as they are usually delivered with a lot ofperipherals.The purpose of this thesis was to develop a system of a mobile application and logical code to a microcontroller that register horizontal forces at sprint starts from an analog source. The collected datawas calculated and transmitted using BLE communication to the mobile application which presentsthe force data to the user.Moreover, the purpose was also to have the acquired force data time-synchronized with a mobile device to make it possible to evaluate events against external sources such as IMU and high-speed film.The result for the logic developed throughout this work demonstrate that it is possible to retrievesampled force data from a microcontroller via BLE communication. It was possible to present thecalculated force data visually to an end user with a mobile application and have the events time synchronized using time synchronization algorithms. However, the results can be further improved bydevelopment of the system.

The feature of the character envisaged here is the overmuch dependence that this woman cherishes towards man. In the second place, the analysis of a clinical case of a 40- years old woman who called herself a Medea of life when she looked for therapy. Finally, Winnicott`s Theory of Human Maturation as a theoretic approach useful to understand the case in question. As a result, the articulation of these points points out to the importance of winnicottian clinic as an alternative care to patients with flaws in primitive development, i.e., in preedipic stage, when is at stake the continuity of the being, not sexuality / O presente trabalho parte de três pontos principais. Em primeiro lugar, o mito de Medéia a mulher que mata os filhos para se vingar do marido. O aspecto enfocado na figura da personagem é a excessiva dependência que essa mulher nutre em relação ao homem. Em segundo, a análise de uma mulher de 40 anos que se autodenominou "uma Medéia da vida" ao procurar terapia, utilizando para isso o método clínico. E, finalmente, a Teoria do Amadurecimento Humano de D. W. Winnicott como abordagem teórica para compreender o caso em questão. O resultado da articulação desses pontos aponta para a importância da clínica winnicottiana como uma alternativa para cuidados com pacientes com falhas no desenvolvimento primitivo, ou seja, na fase pré-edípica, quando o que está em jogo é a continuidade do ser e não a sexualidade

Analýza českých mluvených projevů nerodilých mluvčích / An Analysis of Verbal Czech Language Usage by Non-native Speakers

Pémová, Petra January 2017 (has links)
(in English): The work in this diploma contains an analysis of speech accuracy and fluency of Russian speaking and English speaking students of Czech language, based on case studies. For these case studies two Russian speaking students and two English speaking students were chosen to take part. The results were compared to the results of one native Czech speaker. The accuracy and fluency analysis was carried out based on the language principles of Rod Ellis. Within the accuracy analysis, the number of error free clauses and the average number of mistakes per one hundred words were measured. Accuracy of speech is examined through concrete grammatical phenomena like the usage of reflexive particle se/si and the usage of the verb to be in the past tense. The work in this diploma also considers the ability of analysed speakers to switch between language codes and to distinguish features of formal and spoken Czech language (spoken language in informal situations). The fluency of speech is studied based on the speech rate of all analysed speakers by counting the number of syllables per one hundred words. Subsequently, the number of false starts, repetition of words or phrases, the frequency of usage of parasite words and hesitation sounds were also examined. One of the diploma hypothesis is the statement...

The Development of a Three Minute Realtime Sampling Method to Measure Social Harmony during Interactions between Parents and their Toddlers with Autism

Cunningham, Isabel L. 08 1900 (has links)
Training parents of a child with autism to increase the frequency of their child's social behavior may improve the quality of parent-child interactions. The purpose of this methodological study was to develop a direct observation method for rapidly sampling social harmony between parents and their toddlers with autism during parent training interactions. The current study used a pre and post probe design, with benchmark comparisons to test the discriminability of the measurement protocol across two sets of data. The first set of data came from pre and post training videos from a parent training program for children with a diagnosis of autism or at risk for a diagnosis. The second set of data came from videos of typically developing toddlers and their parents. The results of the study show that the measurement system differentiated in the level of harmonious engagement between the benchmark sample and the sample including children diagnosed with autism. The results are discussed in the context of future directions and the utility of the measurement system for behavior analytic practices in parent training and other settings where rapport and complex interactional behaviors are an intervention priority.

Kulturně společenské centrum u brněnské přehrady - architektonická studie objektů pro kulturně společenské i sportovní akce / The cultural and community centre near the Brno dam - the architectural design of buildings for cultural and social and sports events

Šmihula, Michal January 2010 (has links)
The design of cultural centre is situated in part Kozia Hôrka( well-known city swimming pool), in its advantage takes natural scenery and calm atmosphere of place. Into action of performance brings a message in form of body of reservoir, function of centre is divided into small parts placed in area Kozia Hôrka. Orientation of objects comes mainly from local natural ispirations. Complex is multifunctional in concept, counts with several sorts of culture - sports events. Whereby the main function of swimming pool is preserved and added for higher comfort of inhabitants. Architecture of objects comes from idea of floating leaf on water level and body of reservoir. Objects stylizely illustrate this idea. The design takes the game of solids of organic and strictly ortogonal shapes. Two mutual opposites, in interaction. Objects smoothy and with respect encroach the environment, which is enough marked by human. Simplicity in used materials ( glass, steel, wood ) give transparency and purity to whole solution.
