Lösning för direktsänd videolänk för produktionen Go’kväll i SVT / Remote located live broadcast solution for contribution for the SVT-production Go’kväll

Frost, Per January 2014 (has links)
Magasinprogrammet Go’kväll sänder i regel fem program per vecka under hela vinterhalvåret. Programmet produceras och sänds ut av SVT allmän-TV i Umeå. Till vissa delar av programmet önskas gäster som uttalar sig om aktuella ämnen. Vid några tillfällen har redaktionen upplevt att man inte kunnat plocka in de mest optimala gästerna för kommentarer på grund av rent logistiska skäl, i regel att den efterfrågade gästen i fråga inte kunnat närvara fysiskt i Umeå, ofta på grund av kort varsel, något som nuvarande programutformning kräver av alla som medverkar i direktsändning. Det som efterfrågades var en lösning för att kunna inkludera konceptet gäst via direktlänk i kortare segment av programmet. I utgångsläget fanns ingen budget eller möjlighet till stora ekonomiska investeringar just för detta ändamål. Problemformuleringen blev därför: Hur implementerar man konceptet gäst via länk med hjälp av de resurser SVT idag och inom den närmsta framtiden förfogar över? TV-verksamheten inom SVT är primärt indelad i tre olika divisioner: allmän-tv (dit hör exempelvis barn-, nöje-, fakta- och kulturprogram), nyheter (nyhetsbevakning, sport, regionala nyheter etc.) och SVTi (teknisk utveckling). Allmän-TV (ATV) produceras av SVT på fyra orter som är Stockholm, Göteborg, Malmö och Umeå. De fyra ATV-orterna har utrustning för att sända HDTV och producerar även i HD. Nyheter, och framförallt de regionala nyheterna inkluderar redan i dagsläget olika direktsända inslag från fältet i sina produktioner men skillnaden är att allt produceras i det gamla SD-formatet. I praktiken innebär detta att HD endast kan sändas mellan ATV-orterna och sedan ut i rutan utan att infrastrukturen ändras. Den stora utmaningen blev följaktligen att hitta en lösning där så mycket av befintlig infrastruktur och personalresurs som möjligt kan utnyttjas och samtidigt möta de krav på bildkvalitet som efterfrågas. Med hjälp av intervjuer och interna dokument kartlades befintliga resurser och resultatet blev att möjligheter för att lösa problemet med hjälp av befintlig infrastruktur och bemanning torde vara fullt genomförbart och möjligt att implementera snarast. / The talk-show Go'kväll (Good evening) broadcast five shows per week during the autumn, winter and spring. The show is produced and broadcasted by the non-news section (ATV) of SVT in Umeå. In some parts of the show, guests who gives comments to various recent events is wanted. Some particular times, the editorial staff has experienced that the most ideal guests could not be present in the show, mainly according to the circumstance that they have to be physically present in the studio in Umeå in order to participate in the show, often made impossible by travel logistics. The production wanted a solution for using the concept of remote located quests participating live via video link in chosen segments of the show. There was no economical budget for the project, so the question was: How to implement the concept of using remote located quests live in Go'kväll, only using present infrastructure and other resources? The TV-operations within the company of SVT is divided into three different divisions, ATV, News section (news, sport) and SVTi (Technichal development). ATV is produced and broadcasted from Stockholm, Gothenburg, Malmö and Umeå. These four facilities produce and broadcast in HD-format while the news division mainly broadcasts in SD. Practically, this means that with no change at all in infrastructure, HD can only be transmitted between and from the ATV-locations. The main challenge then, become finding a solution where as much as possible of resources in terms of infrastructure and staff could be used and also meet the requirements of video quality. By making interviews and reading internal working documents, existing resources were surveyed and the results shows that possibilities to solve the problem using existing technical infrastructure and labour exists and should be implementable instantly, if requested.

The impact of inflation risk on forward trading and production

Broll, Udo, Wong, Kit Pong 11 September 2014 (has links) (PDF)
This note examines the behavior of a competitive firm that faces joint price and inflation risk. Given that the price risk is negatively correlated with the inflation risk in the sense of expectation dependence, the firm optimally opts for an over-hedge if the firm's coefficient of relative risk aversion is everywhere no greater than unity. Furthermore, banning the firm from forward trading may induce the firm to produce more or less, depending on whether the price risk premium is positive or negative, respectively. While the price risk premium is unambiguously negative in the absence of the inflation risk, it is not the case when the inflation risk prevails. In contrast to the conventional wisdom, forward hedging needs not always promote production should firms take in inflation seriously.

Ambiguity and the Incentive to Export

Broll, Udo, Wong, Kit Pong 11 September 2014 (has links) (PDF)
This paper examines the optimal production and export decisions of an international firm facing exchange rate uncertainty when the firm's preferences exhibit smooth ambiguity aversion. Ambiguity is modeled by a second-order probability distribution that captures the firm's uncertainty about which of the subjective beliefs govern the exchange rate risk. Ambiguity preferences are modeled by the (second-order) expectation of a concave transformation of the (first-order) expected utility of profit conditional on each plausible subjective distribution of the exchange rate risk. Within this framework, we show that ambiguity has no impact on the firm's propensity to export to a foreign country. Ambiguity and ambiguity aversion, however, are shown to have adverse effect on the firm's incentive to export to the foreign country.

Analyse und Bewertung ausgewählter zukünftiger Biokraftstoffoptionen auf der Basis fester Biomasse

Müller-Langer, Franziska 23 February 2015 (has links) (PDF)
Etwa ein Drittel des Gesamtendenergieverbrauchs entfällt auf den Transportsektor, dessen Energieverbrauch zu rund 98 % über fossile Kraftstoffe (maßgeblich Mineralöl) abgedeckt wird [70], [71], [91]. Gleichzeitig ist der Transportsektor eine der Hauptursachen für den Ausstoß anthropogener Treibhausgasemissionen. Mobilität (insbesondere von Personen und Gütern) ist für die gesellschaftliche und wirtschaftliche Entwicklung unverzichtbar und nach wie vor ein überdurchschnittlich wachsender Bereich [103]. Weltweit wird sich die Anzahl der Kraftfahrzeuge von ca. 700 Mio. Personenwagen im Jahr 2000 auf etwa 1,3 Mrd. Personenwagen im Jahr 2030 nahezu verdoppeln; gleiches gilt für den damit einhergehenden Verbrauch an Endenergie [302]. Hingegen wird in Deutschland von einem um 9 % sinkenden Energieverbrauch gegenüber 2005 auf 2 EJ/a im Jahr 2030 ausgegangen; in den Mitgliedsstaaten der EU-27 hingegen wird ein Anstieg um 14 % gegenüber 2005 auf 17,7 EJ/a im Jahr 2030 erwartet [71], [72].

DAISY book production at the National Organization of the Blind (ONCE)

Pérez Arnaez, Rafael 15 June 2011 (has links) (PDF)
DAISY book production at the ONCE, with the digitization and subsequent reformatting of our stacks to the DAISY standard, has pursued two key objectives: to digitize our collection as quickly and efficiently as possible and to lower the production costs of digital talking books in DAISY format. This discussion describes the highlights of that process.

Towards a ready-to-use, DAISY-aware library management system

Hinderer, Sebastian, Burger, Dominique, Marmol, Bruno 12 July 2011 (has links) (PDF)
Both integrated library management systems and DAISY production and manipulation tools become widespread. We study how they could be combined to build a ready-to-use digital library with DAISY as its core format. The obtained framework should cover the entire book processing, from digital files provided either by publishers or by scanning printed material, until the delivery of DAISY content to end-users in a possibly secured way. We first give a functional description of the framework we have in mind. Then, we examine the existing tools of interest and give some tracks for further software developments.
