Autonomous Vehicles and Commercial Real Estate

Hardly a day goes by without the release of a handful of news stories about autonomous vehicles (or AVs for short). The proverbial “tipping point” of awareness has been reached in the public consciousness as AV technology is quickly becoming the new focus of firms from Silicon Valley to Detroit and beyond. Automation has, and will continue to have far-reaching implications for many human activities, but for driving, the technology is here. Google has been in talks with automaker Ford (1), Elon Musk has declared that Tesla will have the appropriate technology in two years (2), GM is paired-up with Lyft (3), Uber is in development-mode (4), Microsoft and Volvo have announced a partnership (5), Apple has been piloting its top-secret project “Titan” (6), Toyota is working on its own technology (7), as is BMW (8). Audi (9) made a splash by sending a driverless A7 concept car 550 miles from San Francisco to Las Vegas just in time to roll-into the 2016 Consumer Electronics Show. Clearly, the race is on.

Pianificazione di coperture fotogrammetriche mediante RPAS

Il seguente elaborato di tesi tratta il problema della pianificazione di voli fotogrammetrici a bassa quota mediante l’uso di SAPR, in particolare è presentata una disamina delle principali applicazioni che permettono di programmare una copertura fotogrammetrica trasversale e longitudinale di un certo poligono con un drone commerciale. Il tema principale sviluppato è la gestione di un volo fotogrammetrico UAV mediante l’uso di applicativi software che permettono all’utente di inserire i parametri di volo in base alla tipologia di rilievo che vuole effettuare. L’obbiettivo finale è quello di ottenere una corretta presa fotogrammetrica da utilizzare per la creazione di un modello digitale del terreno o di un oggetto attraverso elaborazione dati in post-processing. La perfetta configurazione del volo non può prescindere dalle conoscenze base di fotogrammetria e delle meccaniche di un veicolo UAV. I capitoli introduttivi tratteranno infatti i principi della fotogrammetria analogica e digitale soffermandosi su temi utili alla comprensione delle problematiche relative al progetto di rilievo fotogrammetrico aereo. Una particolare attenzione è stata posta sulle nozioni di fotogrammetria digitale che, insieme agli algoritmi di Imagine Matching derivanti dalla Computer Vision, permette di definire il ramo della Fotogrammetria Moderna. Nei capitoli centrali verranno esaminate e confrontate una serie di applicazioni commerciali per smartphone e tablet, disponibili per sistemi Apple e Android, per trarne un breve resoconto conclusivo che le compari in termini di accessibilità, potenzialità e destinazione d’uso. Per una maggiore comprensione si determinano univocamente gli acronimi con cui i droni vengono chiamati nei diversi contesti: UAV (Unmanned Aerial Vehicle), SAPR (Sistemi Aeromobili a Pilotaggio Remoto), RPAS (Remotely Piloted Aicraft System), ARP (Aeromobili a Pilotaggio Remoto).

Cambios de CEO y presidentes de directorio en el Perú : un enfoque para las empresas peruanas con mayor frecuencia de negociación en la BVL de 1992 al 2014

Esta investigación tiene como objetivo determinar si los anuncios de cambios de CEO y presidentes de Directorio de las empresas listadas en la Bolsa de Valores de Lima (BVL) afectan el valor de la firma en los días cercanos al anuncio. Fue la pronta salida de Steve Jobs como CEO de Apple Inc., a causa de una enfermedad mortal, lo que nos generó el cuestionamiento respecto a cuál sería el desempeño que tienen las acciones cuyas compañías pasan por eventos similares. Como se sabe, el mercado castigó la acción de Apple el día de la muerte de Steve Jobs, con caídas superiores al 2% el día del anuncio. ¿Tendrían los mercados desarrollados y emergentes el mismo comportamiento?, ¿los eventos de cambio de CEO generan las mismas reacciones en los países emergentes? Grande fue nuestra sorpresa al observar, a nivel local, cambios en la gerencia general como en Backus & Johnston (3/9/2013) sin un efecto significativo en el mercado, pues incluso el mercado no negoció dicho valor hasta el 19/9/2013. Con el objetivo de obtener una respuesta a las consultas inicialmente planteadas, se aplicó la metodología denominada Event Analysis, la cual ya ha sido utilizada para evaluar la existencia de retornos anormales ante cambios en CEO y presidentes de Directorio en mercados desarrollados como EE. UU., Países Bajos, Australia, España, etc., y también en mercados emergentes como Colombia, Chile y México. Nuestro estudio para el mercado peruano consistió en una muestra conformada por las cincuenta empresas cuyas acciones son las de mayor frecuencia de negociación en la BVL. Se tomó en consideración todos los eventos de cambio de CEO y presidentes de Directorio entre 1992 y el 2014. De acuerdo con los resultados de la investigación realizada, la existencia de retornos anormales en los cambios de CEO y presidentes de Directorio no son estadísticamente significativos, por lo que no podrían ser usado para generar estrategias del tipo Event-driven por parte de los hedge funds. La razón predominante es la alta volatilidad de los resultados y la poca profundidad del mercado que cuenta con poca liquidez; asimismo, el hecho de tener eventos relevantes que no son tomados en cuenta por el mercado.

Future Bloom and Blossom Frost Risk for Malus domestica Considering Climate Model and Impact Model Uncertainties

The future bloom and risk of blossom frosts for Malus domestica were projected using regional climate realizations and phenological (= impact) models. As climate impact projections are susceptible to uncertainties of climate and impact models and model concatenation, the significant horizon of the climate impact signal was analyzed by applying 7 impact models, including two new developments, on 13 climate realizations of the IPCC emission scenario A1B. Advancement of phenophases and a decrease in blossom frost risk for Lower Saxony (Germany) for early and late ripeners was determined by six out of seven phenological models. Single model/single grid point time series of bloom showed significant trends by 2021-2050 compared to 1971-2000, whereas the joint signal of all climate and impact models did not stabilize until 2043. Regarding blossom frost risk, joint projection variability exceeded the projected signal. Thus, blossom frost risk cannot be stated to be lower by the end of the 21st century despite a negative trend. As a consequence it is however unlikely to increase. Uncertainty of temperature, blooming date and blossom frost risk projection reached a minimum at 2078-2087. The projected phenophases advanced by 5.5 d K-1, showing partial compensation of delayed fulfillment of the winter chill requirement and faster completion of the following forcing phase in spring. Finally, phenological model performance was improved by considering the length of day.

UNPROVEN INNOVATION: IPADS IN K-12 ENVIRONMENTS

Nationally, the education sector spends more than 5 billion dollars annually on digital tools, “yet seldom are technology solutions factored into any viable equation for improving student academic achievement” (Moersch, 2014, p. ix). Consider the following case in point: In July 2014, Apple announced that in just 3 years, the company had sold more than13 million iPads to educational institutions worldwide (Cavanagh, 2014). Put into perspective, that represents more than 5.2 billion dollars spent by the education industry to purchase iPads, which is the equivalent of the annual salaries of 89,655 teachers (“High School Teacher: Salary,” 2014). Despite such vast expenditures, there have been very few attempts to evaluate the efficacy of these digital tools on improving academic achievement. This research involved a quantitative data review of participant (student and teacher) survey data to explore one of the country’s largest K-12 iPad implementation undertakings in an effort to identify (a) best practices and (b) lessons learned from implementing the iPad into K-12 educational environments. It should be noted that the school system forming the basis of this research already had administered and collated the surveys used in this study.

A new species of gall midge (Diptera: Cecidomyiidae) feeding on ornamental Cordyline fruticosa(Asparagaceae) in Australia

Larvae of an undescribed gall midge were found feeding on leaves and stems within leaf sheaths and between leaf blades of potted plants of Cordyline fruticosa (Asparagaceae) in a production nursery in Queensland. The following varieties of the host plant were infested: Apple Blossom', Glauca', Kilauea', Negra', Pink Diamond, 'Purple Prince' and Willy's Gold'. The new species, Dasineura cordylineaeKolesik sp. nov., is described and its cytochrome oxidase unit I mitochondrial gene segment is sequenced. The new species is the first known gall midge feeding on a plant species of the genus Cordyline. Orange larvae induce oval shallow swellings on the leaf and stem tissue, which becomes necrotised during the later stage of larval feeding. Necrotic areas remain visible to the end of leaves' lives and decrease the market value of the plants. In the production nursery investigated, the lesions caused by the gall midge provided an entry for a fungal infection by Fusarium sp. inflicting further injury to plants. Larvae of the new species were preyed on by larvae of Gaurax sp. (Diptera: Chloropidae). This is the first worldwide record of Chloropidae preying on Cecidomyiidae.

Preocupações, problemas e interesses dos alunos no quadro da gestão curricular

O estudo e a evolução das teorias curriculares têm apontado, nos sistemas de ensino ocidentais, para a necessidade de o currículo, definido a nível central, poder ser reconstruído e gerido de forma flexível e em articulação com as pessoas e os contextos em que se supõe ser materializado (Apple, 1997; Escudero, 2007; Giroux, Penna & Pinar 1981; McDaniel, 2008). Significa isto que a escola e o professor podem e devem desempenhar um papel central na reconstrução dos programas de ensino e das orientações ministeriais. Neste sentido, a elaboração de projetos educativos e curriculares constitui um espaço fulcral para essa reconstrução, embora em dados disponíveis ao nível do nosso pais se reconheçam que nem sempre as escolas e/ou os professores encaram a elaboração dos projetos educativos e curriculares como instrumento de deliberação autónoma em relação aos diversos componentes do currículo (Esteves, 2002), podendo facilmente resultar numa tarefa formal e burocrática, “lateral e exterior em relação ao currículo nuclear a desenvolver quotidianamente” (Freire, 2005, p. 89). Para tal situação podem contribuir diversas variáveis, desde politicas de controlo externo dos resultados escolares as questões mais técnicas, entre as quais se inscreve a capacidade de se planear a ação educativa com os atores dando, também, expressão aos seus interesses e desejos e/ou considerando aspetos que possam ser para eles significativos. É particularmente no âmbito desta última capacidade que, na presente reflexão, se aprofunda o levantamento de problemas em contexto escolar, de modo a que estes possam ser objeto de atenção aquando do planeamento da intervenção educativa.

La distribution et la diffusion du livre québécois dans la sphère numérique : le cas de l’Entrepôt numérique (ANEL – De Marque)

En 2008, le Québec fait son entrée dans le marché du livre numérique. Cette année-là, l’Association nationale des éditeurs de livres du Québec (ANEL) s’associe avec l’entreprise De Marque pour créer l’Entrepôt numérique (www.entrepotnumerique.com), une plateforme de diffusion et de distribution de livres numériques québécois. Sa structure permet de stocker et de gérer les fichiers numériques, tout en offrant aux éditeurs une interface personnalisée afin que chacun puisse commercialiser ses titres en quelques étapes simples. Dès le départ, les instigateurs de ce projet font le pari de mettre en place une infrastructure de diffusion-distribution propre aux Québécois et qui répond à l’internationalisation du marché du livre. Mais les enjeux sont nombreux pour les professionnels du système-livre du Québec qui tentent de s’adapter aux nouvelles structures et de se frayer un chemin dans la sphère numérique. À la fois d’ordre technologique, économique et culturel, ces enjeux posent la double question de la commercialisation d’une nouvelle forme de livre et de la présence de la culture québécoise sur le web. En effet, face à la multiplication des titres et devant l’espace infini de la Toile, comment assurer la circulation et la promotion du livre numérique ? Comment adapter les circuits traditionnels à un nouveau format de livre qui se distingue de la forme fixe du livre imprimé que l’on connaît ? Et comment, surtout, la culture québécoise peut-elle prendre place auprès de géants internationaux comme Amazon, Google ou Apple ? Ayant précisément pour mandat d’offrir une solution de diffusion numérique simple et efficace aux éditeurs québécois et canadiens-français, l’Entrepôt numérique distribue la production de 148 éditeurs, donnant ainsi aux lecteurs un accès à un catalogue mutualisé comptant 17 144 publications. Plus de 750 000 livres numériques ont été vendus depuis 2009 et de nombreuses ententes de partenariat ont été signées avec 194 revendeurs provenant de 58 pays. Or, en assurant la circulation et la commercialisation des titres dans l’espace numérique, l’Entrepôt numérique participe à la mutation du secteur de la diffusion-distribution au Québec. Il illustre ainsi les évolutions techniques, économiques et structurelles du marché. S’intéresser à l’Entrepôt numérique comme objet d’étude, c’est donc s’intéresser aux enjeux (technologiques, culturels, économiques) pouvant se dégager des nouvelles stratégies de circulation et de commercialisation du livre numérique implantées au sein de la filière québécoise.  Trois chapitres composent ce mémoire. Le premier propose un historique de l’Entrepôt numérique. En décrivant à la fois les enjeux de départ, les acteurs impliqués et l’évolution de la plateforme, il permet de situer les conditions culturelles, commerciales et éditoriales ayant permis le développement de cette plateforme. Le deuxième chapitre, qui examine les mécanismes de distribution via l’Entrepôt numérique, met en lumière les différents jalons qui marquent le passage de la distribution traditionnelle à la distribution du livre numérique. Enfin, le troisième chapitre porte sur les mécanismes de diffusion du livre numérique de la plateforme et illustre ainsi les nouvelles conditions de promotion du livre dans la sphère numérique. En somme, la présentation de l’historique de l’Entrepôt numérique et l’examen des mécanismes de diffusion et de distribution de la plateforme permettent d’offrir une meilleure préhension des transformations et enjeux émanant de l’industrie du livre numérique au Québec, entre 2007 et 2015.

Postharvest light treatments increase skin blush in mango fruit

Skin colour is an important quality parameter that influences mango fruit marketability. The mango industry is interested in controlled induction of skin blush in mangoes. It is desirable to understand the control of anthocyanin accumulation in mango skin. Among environmental factors known to induce anthocyanin accumulation in plants, light is the most studied. Light exposure induces pigmentation in various fruits, including apple, strawberry and grape. The effect of different light qualities on skin blush in mango fruit has received relatively little attention. The objective of this study was to assess anthocyanin accumulation and blush in response to blue, red and far red light from light-emitting diodes (LEDs) as applied to harvested mango fruit skin during storage at 12°C. Except for red light, the other wavelengths induced anthocyanin accumulation and skin blush as compared to the dark control treatment. Anthocyanin concentration and a∗ values were highest in blue light exposed fruit skin. This wavelength enhanced phenylalanine ammonia lyase activity in the mango skin, which may be associated with increased pigmentation. LED light treatment did not affect other fruit quality parameters at 21 days of storage, including firmness, total soluble solids and titratable acidity. Overall, the findings suggest that postharvest treatment with blue light can induce skin blush in mango fruit, which potentially may enhance their commercial value.

Desenvolvimento e aplicação de modelo de calibração multivariada para determinação de açúcares e ácidos orgânicos em bebidas comerciais utilizando espectroscopia no infravermelho

The routine analysis for quantization of organic acids and sugars are generally slow methods that involve the use and preparation of several reagents, require trained professional, the availability of special equipment and is expensive. In this context, it has been increasing investment in research whose purpose is the development of substitutive methods to reference, which are faster, cheap and simple, and infrared spectroscopy have been highlighted in this regard. The present study developed multivariate calibration models for the simultaneous and quantitative determination of ascorbic acid, citric, malic and tartaric and sugars sucrose, glucose and fructose, and soluble solids in juices and fruit nectars and classification models for ACP. We used methods of spectroscopy in the near infrared (Near Infrared, NIR) in association with the method regression of partial least squares (PLS). Were used 42 samples between juices and fruit nectars commercially available in local shops. For the construction of the models were performed with reference analysis using high-performance liquid chromatography (HPLC) and refractometry for the analysis of soluble solids. Subsequently, the acquisition of the spectra was done in triplicate, in the spectral range 12500 to 4000 cm-1. The best models were applied to the quantification of analytes in study on natural juices and juice samples produced in the Paraná Southwest Region. The juices used in the application of the models also underwent physical and chemical analysis. Validation of chromatographic methodology has shown satisfactory results, since the external calibration curve obtained R-square value (R2) above 0.98 and coefficient of variation (%CV) for intermediate precision and repeatability below 8.83%. Through the Principal Component Analysis (PCA) was possible to separate samples of juices into two major groups, grape and apple and tangerine and orange, while for nectars groups separated guava and grape, and pineapple and apple. Different validation methods, and pre-processes that were used separately and in combination, were obtained with multivariate calibration models with average forecast square error (RMSEP) and cross validation (RMSECV) errors below 1.33 and 1.53 g.100 mL-1, respectively and R2 above 0.771, except for malic acid. The physicochemical analysis enabled the characterization of drinks, including the pH working range (variation of 2.83 to 5.79) and acidity within the parameters Regulation for each flavor. Regression models have demonstrated the possibility of determining both ascorbic acids, citric, malic and tartaric with successfully, besides sucrose, glucose and fructose by means of only a spectrum, suggesting that the models are economically viable for quality control and product standardization in the fruit juice and nectars processing industry.

mHealth in Urology: A Review of Experts' Involvement in App Development

Smartphones are increasingly playing a role in healthcare and previous studies assessing medical applications (apps) have raised concerns about lack of expert involvement and low content accuracy. However, there are no such studies in Urology. We reviewed Urology apps with the aim of assessing the level of participation of healthcare professionals (HCP) and scientific Urology associations in their development.

Nutritional and chemical characterization of food products enriched with biological produced fruits of Vaccinum myrtillus L

Vaccinum myrtillus L. belongs to Ericaceae family, being commonly known for its sweet small fruits: the blueberries. Widely consumed in fresh, these fruits are also used in jams and marmalades due to their digestive and hypoglycemic properties and also due to the presence of several bioactive compounds [!]. Therefore, it has become a very appealing matrix in the development of functional products that, beyond their nutritional properties, will add a long-term beneficial physiological/health effect [2]. In the present work, three novel blueberry based products developed by RBR Foods Company (Portugal), were characterized in terms of their nutritional and chemical properties: carbohydrates, ash, proteins, fat and energetic value (following official methods of food analysis), fatty acids profile (by CG-FID), soluble sugars (by HPLCRI), organic acids (by HPLC-DAD) and tocopherols (by HPLC-fluorescence). The products result from a mixture of the fruits with rose petals (PI), marigold petals (P2) and apple and goji berries (P3). The blueberry fruits were used as control sample. The nutritional profile of the novel products was very similar to the control sample: the carbohydrates were the most abundant macronutrient, followed by proteins and total fat. Regarding sugars, fructose, glucose and sucrose were identified in all the samples. P 1 and P2 didn't show significant differences in comparison to the control, however, P3 revealed a lower concentration of sugars. In terms of fatty acids composition, all the studied samples presented higher contents in polyunsaturated fatty acids, especially due to the contribution of linoleic and alinolenic acids. The results of tocopherols revealed that the control sample only presented two isoforrns of tocopherols, a- and y-tocopherol, being the same observed in P3. However, P 1 revealed the presence of all the isoforrns of tocopherols, while P2 was lacking otocopherol; which is related with the contribution of rose and marigold petals, respectively. The a-tocopherol isoforrn was the most abundant in all the studied samples. Overall, this work contributed to the nutritional characterization of novel blueberry based products and is a part of a wider project that aims the detailed study of these products, namely their potential to be used as functional foods.
