Barnum, Jil 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / Hierarchical Data Format (HDF) is a public domain standard for file formats which is documented and maintained by the National Center for Super Computing Applications. HDF is the standard adopted by the F-22 program to increase efficiency of avionics data processing and utility of the data. This paper will discuss how the data processing Integrated Product Team (IPT) on the F-22 program plans to use HDF for file format standardization. The history of the IPT choosing HDF, the efficiencies gained by choosing HDF, and the ease of data transfer will be explained.

Specifika alternativních rozhlasovýh formátů pro posluchače mladších věkových kategorií / The Specifies of Alternative Radio Formats Targeted Towards Young Adult Listeners

Kopecká, Mariana January 2013 (has links)
The thesis on The Specifies of Alternative Radio Formats Targeted Towards Young Adult Listeners reflects radio broadcasting which is mainly targeted on young listeners. It focuses on the current image of this broadcasting in terms of Czech media environment. At first, the thesis familiarises its readers with basic terms that are used in connection with the issue of radio formats. Then it continues with the overview of music and journalism genres, which are crucial for the distinction between various radio formats. The closing chapter of the theoretical part introduces two radio stations which were chosen to represent the cathegory of alternative radio format; these are Radio 1 and Radio Wave. In the following empirical part, a one-week broadcasting of these particular stations is being analyzed. Afterwards, a summary of the main similarities and differences between the stations is presented. The main attributes of alternative radio format as such are summed up then. In the final chapter, the thesis presents an additional public opinion research, which explores the image of alternative radio held by young audience. For the sake of clarity, the findings of this thesis are presented from the most general facts to the most concrete ones.

Les "produits résiduaires organiques" pour une intensification écologique de l'agriculture : ressources, déchets ou produits ? : sociologie des formats de valorisation agricole / "Residual organic product" for ecological intensification of agriculture : resource, waste or product? : sociology of agricultural valorization formats

Joncoux, Steve 21 November 2013 (has links)
Les "déchets" organiques sont utilisés pour fertiliser les terres agricoles depuis l’avènement de l’agriculture. Longtemps considérés comme des ressources, les résidus organiques urbains ne deviennent des déchets qu’au début du 20ème siècle. Ils sont alors délaissés par le monde agricole et entassés dans des décharges. Aujourd’hui leur valorisation s’impose comme un des axes majeurs des politiques de gestion des déchets. En parallèle, l’agriculture cherche les voies d’une augmentation de la production qui soit respectueuse de l’environnement. A la croisée de ces deux problématiques, le programme de recherche ANR "ISARD", qui constitue à la fois le cadre et l’objet de cette étude, vise à une "Intensification écologique des Systèmes Agricoles par le Recyclage des Déchets". Différents "produits résiduaires organiques" sont ainsi appelés à devenir de véritables intrants agricoles, sûrs et efficaces, participant à l’intensification de l’agriculture. Leur intégration dans des dispositifs industriels de normalisation, leur conférant le statut de produit commercial, apparaît comme le moyen le plus adapté pour répondre à ces attentes. En suivant les enseignements des sociologies pragmatistes prenant en compte le rôle des objets dans l’action, c’est à la description des différentes formes sociotechniques de la valorisation agricole (ressource, déchet, produit) que se consacre ce travail. La prise en compte d’une pluralité de formes de valorisation permet d’insister sur les déplacements induits par une logique "produit" et les reconfigurations qu’elle provoque, notamment par rapport à la pluralité des mondes agricoles. / Organic "waste" has been used to fertilize agricultural land since the very beginning of agriculture. Urban organic residue, which has been considered a resource for a long time, only became a real "waste" at the beginning of 20th century, being then abandoned by farmers and packed into dumps. Today, after its reduction, its valorisation is becoming a major goal of waste management public policies. At the same time, the agricultural world is trying to reach an increased production with less environmental impact. Poised between these two issues, the ISARD research program, which is both the subject and the framework of this study, aims at an "ecological intensification of agricultural production systems through waste recycling". As a consequence, various "residual" organic matters are destined to become safe and efficient agricultural inputs, taking part of the agricultural intensification by strengthening the fertilization ecosystem services naturally provided by soils. Their integration in normalized industrial systems, making them real commercial products, seems to be the best way to come up to these expectations. This work devotes itself to describe the various socio-technical forms of agricultural valorisation (resource, waste, product), following the teachings of pragmatist sociologists by taking the role of objects in action into account. The plurality of valorisation forms allows this study to lay stress on the changes brought by a "product" approach and the related social reconfiguration possibly conflicting with a number of agricultural worlds.

Outils de spatialisation sonore pour terminaux mobiles : microphone 3D pour une utilisation nomade / Tools of sound spatializing for mobile terminals : 3D microphone for a mobile usage

Palacino, Julian 04 November 2014 (has links)
Les technologies nomades (smartphones, tablettes, . . . ) étant actuellement très répandues,nous avons souhaité, dans le cadre de cette thèse, les utiliser comme vecteur pour proposer au grand public des outils de spatialisation sonore. La taille et le nombre de transducteurs utilisés pour la captation et la restitution sonore spatialisée sont à ce jour la limitation principale pour une utilisation nomade. Dans une première étape, la captation d’un opéra pour une restitution sur des tablettes tactiles nous a permis d’évaluer les technologies audio 3D disponibles aujourd’hui. Les résultats de cette évaluation ont révélé que l’utilisation des quatre capteurs du microphone Soundfield donne de bons résultats à condition d’effectuer un décodage binaural adapté pour une restitution sur casque. Selon une approche inspirée des méthodes de localisation de source et le concept de format « objet », un prototype de prise de son 3D léger et compact a été développé. Le dispositif microphonique proposé se compose de trois capsules microphoniques cardioïdes. A partir des signaux microphoniques, un algorithme de post-traitement spatial est capable, d’une part, de déterminer la direction des sources et, d’autre part, d’extraire un signal sonore représentatif de la scène spatiale. Ces deux informations permettent ainsi de caractérisercomplètement la scène sonore 3D en fournissant un encodage spatial offrant le double avantage d’une compression de l’information audio et d’une flexibilité pour le choix du système de reproduction. En effet, la scène sonore ainsi encodée peut être restituée en utilisant un décodage adapté sur n’importe quel type de dispositif.Plusieurs méthodes de localisation et différentes configurations microphoniques (géométrie et directivité) ont été étudiées.Dans une seconde étape, l’algorithme d’extraction de l’information spatiale a été modifié pour prendre en compte les caractéristiques réelles in situ des microphones.Des méthodes pour compléter la chaîne acoustique sont proposées permettant la restitution binaurale ainsi que sur tout autre dispositif de restitution. Elles proposent l’utilisation de capteurs de localisation présents sur les terminaux mobiles afin d’exploiter les capacités qu’ils offrent aujourd’hui. / Mobile technologies (such as smartphones and tablets) are now common devices of the consumer market. In this PhD we want to use those technologies as the way to introduce tools of sound spatialization into the mass market. Today the size and the number of traducers used to pick-up and to render a spatial sound scene are the main factors which limit the portability of those devices. As a first step, a listening test, based on a spatial audio recording of an opera, let us to evaluate the 3D audio technologies available today for headphone rendering. The results of this test show that, using the appropriate binaural decoding, it is possible to achieve a good binaural rendering using only the four sensors of the Soundfield microphone.Then, the steps of the development of a 3D sound pick-up system are described. Several configurations are evaluated and compared. The device, composed of 3 cardioid microphones, was developed following an approach inspired by the sound source localization and by the concept of the "object format encoding". Using the microphone signals and an adapted post-processing it is possible to determine the directions of the sources and to extract a sound signal which is representative of the sound scene. In this way, it is possible to completely describe the sound scene and to compress the audio information.This method offer the advantage of being cross platform compatible. In fact, the sound scene encoded with this method can be rendered over any reproduction system.A second method to extract the spatial information is proposed. It uses the real in situ characteristics of the microphone array to perform the sound scene analysis.Some propositions are made to complement the 3D audio chain allowing to render the result of the sound scene encoding over a binaural system or any king of speaker array using all capabilities of the mobile devices.

Documenting the implementation of sandtray therapy with clients in a rural school

Oosthuizen, Corneli January 2017 (has links)
The purpose of this study was to document the process of ASL students (n=12: male=1; female=11) using sandtray therapy as educational psychology assessment and intervention technique, with young people (Grade Nine clients, n=65) in a high-risk, highneed rural school. The aim of the study was to inform knowledge on educational psychology intervention in South Africa given the need for knowledge on relevant psyhological techniques in an ecology of resource constraints, adversity and diversity. The Common Factors Model of therapeutic alliance framed the study by taking cognisance of the therapeutic relationship and therapist skills in the use of sandtray therapy with clients in the given context. A single design case study was used with a phenomenological epistemology. Qualitative data sources included observations (captured in field notes), observations (captured visually and audiovisually), as well as ASL students’ written reflections. Thematic data analysis revealed three main themes: the sandtray process and format used in a rural school; the role of the sandtray in therapeutic alliance; and the enabling and restricting roles of the rural school context during the sandtray therapy. The research findings indicated that by making certain adaptations to the standard sandtray therapy process, it could be implemented successfully as educational psychology assessment and intervention technique with clients in a high risk high need rural school. Steps that could be implemented according to the standard process and format of sandtray therapy included introduction of the sandtray and miniatures, the postcreation phase as well as documenting the completed sandtray. Steps that were adapted for implementation within the rural school context included the setup step, the creation of the sandtray as well as the cleanup of the sandtray. These adaptations were necessary as a result of certain barriers and enablers within the context of the rural school. Barriers included multilingualism, lack of privacy and group format constraints. The sandtray itself, selection of miniatures as well as the collectivist nature of clients’ culture were identified as enablers. This study can therefore inform knowledge on Educational Psychology intervention in South Africa. / Dissertation (MEd)--University of Pretoria, 2017. / Educational Psychology / MEd / Unrestricted

The Effect of Item Format on Computation Subtest Scores of Standardized Mathematics Achievement Tests

Carcelli, Larry 01 May 1981 (has links)
The effect on childrens' scores of different item formats used in standardized mathematics achievement tests was investigated. Second grade students were given a mathematics computation test using formats derived from five standardized achievement tests. Identical content was tested with each format . Differences in test scores between types r0f formats were statistically significant at p(.001 (F = 45.25). These results indicate that what a student appears to know is substantially influenced by the format of the particualar test used in measuring achievement. These differences are not accounted for by the rno~mative scaling of the different tests. Greater attention should be ~i,en to the effect of test item format in selecting and administering cac1 i evemen t tests.

An Overview Of An Instrumentation Hardware Abstraction Language

Hamilton, John, Fernandes, Ronald, Koola, Paul, Jones, Charles H. 10 1900 (has links)
ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / In this paper we provide the motivation for a neutral instrumentation hardware abstraction language that is focused on the description and control of instrumentation systems and networks. We also describe the design approach and structure of such a language that meets the needs. The language design is described according to the three roles it must serve: (1) as a descriptive language for specifying and describing the components and configuration of an instrumentation system, (2) as a command language for issuing configuration and data commands to instrumentation hardware and (3) as a query language for requesting the current state of instrumentation hardware.

Meric, Burak, Graul, Michael, Fernandes, Ronald, Jones, Charles H. 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper presents the description of a new XML-based data display language called Data Display Markup Language (DDML) that can be used as an interlingua for different data display configuration formats. Translation of data display configuration between various vendor- formats can be accomplished by translating in and out of DDML. The DDML can also be used as a vendor-neutral format for archiving and retrieving display configurations in a test and evaluation (T&E) configuration repository.

Practical Decom List Switching

Devlin, Steve 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada / With more complex vehicle designs, the frequency and number of measurements contained in telemetry data streams has dramatically increased. One way of improving the use of bandwidth is to change the sample rate, quantity, or type of measurements dynamically. A telemetry front end must be programmable to handle different formats. In a front end that decommutates and routes measurements, a decom list is a control program, which defines the location, size, orientation, and identity of the measurements. To deal with dynamic format changes, a telemetry front end must be able to switch between decom lists. A practical approach to decom list switching must address the needs of error avoidance, packet switching, and the location of switching keys in any portion of the format. Switching between formats should not be restricted to a preprogrammed sequence, but should allow multiple destinations from a particular decom list. A practical and flexible implementation of decom list switching is detailed along with an explanation of how this implementation solves a variety of decommutation problems.
