New methods to reduce leakage errors in planar near-field measurements

This paper describes two methods to cancel the effect of two kinds of leakage signals which may be presented when an antenna is measured in a planar near-field range. One method tries to reduce leakage bias errors from the receiver¿s quadrature detector and it is based on estimating the bias constant added to every near-field data sample. Then, that constant is subtracted from the data, removing its undesired effect on the far-field pattern. The estimation is performed by back-propagating the field from the scan plane to the antenna under test plane (AUT) and averaging all the data located outside the AUT aperture. The second method is able to cancel the effect of the leakage from faulty transmission lines, connectors or rotary joints. The basis of this method is also a reconstruction process to determine the field distribution on the AUT plane. Once this distribution is known, a spatial filtering is applied to cancel the contribution due to those faulty elements. After that, a near-field-to-far-field transformation is applied, obtaining a new radiation pattern where the leakage effects have disappeared. To verify the effectiveness of both methods, several examples are presented.

Student Independent Projects Environmental Studies 2007: Redesigning the Corner Brook Waterfront

In recent decades, urban planning has seen a rise in waterfront revitalization. This is important concerning Corner Brook, where the possible permanent closure of the Mill would have devastating consequences for the surrounding area. Corner Brook is located on the West Coast of Newfoundland, Canada, and has a population of 20,083 (WWW.statcan.ca, 2007). Corner Brook Pulp and Paper Ltd. (CBP&P) dominates the local economy and is located on the city's waterfront. With the realization that the heart of any city is the waterfront, if there is one present, many cities started revitalization trend in order to bring life back to the community and restore the local economy (Robertson, 1999). In the past, waterfronts were dominated with industry, shipping, and the navy. Today, the focus has shifted to leisure, recreation, tourism, and residential and commercial activity. Along with economic factors, the visual aspect of the waterfront is also Important (Albrecht, Bode, & Evers, 2003; Hoffman, 1999). Although this trend started out larger cities, such as Toronto, it has now spread to smaller centers, similar to the size of Corner Brook (Hoyle, 2000). What differs between the various sizes of the cities is what the main focus of the waterfront will be following the revitalization. With the tourism economy making a strong foothold in Newfoundland, the waterfront would provide the possibility to extend it even further. Yet, the most important aspects of the new waterfront will be to ensure environmentally safe measures (Slocombe, 1993) and making sure that as many jobs as possible will be generated. The generation of new jobs is especially important considering the loss of the Mill, which has provided the city and surrounding area with paying employment.

Contrary Voices: Heine, Holderlin, and Goethe in the music of Hanns Eisler

Contrary Voices examines composer Hanns Eisler’s settings of nineteenth-century poetry under changing political pressures from 1925 to 1962. The poets’ ideologically fraught reception histories, both under Nazism and in East Germany, led Eisler to intervene in this reception and voice dissent by radically fragmenting the texts. His musical settings both absorb and disturb the charisma of nineteenth-century sound materials, through formal parody, dissonance, and interruption. Eisler’s montage-like work foregrounds the difficult position of a modernist artist speaking both to and against political demands placed on art. Often the very charisma the composer seeks to expose for its power to sway the body politic exerts a force of its own. At the same time, his text-settings resist ideological rigidity in their polyphonic play. A dialogic approach to musical adaptation shows that, as Eisler seeks to resignify Heine’s problematic status in the Weimar Republic, Hölderlin’s appropriation under Nazism, and Goethe’s status as a nationalist symbol in the nascent German Democratic Republic, his music invests these poetic voices with surprising fragility and multivalence. It also destabilizes received gender tropes, in the masculine vulnerability of Eisler’s Heine choruses from 1925 and in the androgynous voices of his 1940s Hölderlin exile songs and later Goethe settings. Cross-reading the texts after hearing such musical treatment illuminates faultlines and complexities less obvious in text-only analysis. Ultimately Eisler’s music translates canonical material into a form as paradoxically faithful as it is violently fragmented.

Desempenho internacional de empresas exportadoras: um modelo estrutural baseado em capacidades organizacionais e ambiente

The internationalization as an organizational phenomenon fundamentally strategic had as theoretical contributions some Schools that throughout the decades 60, 70, and 80 developed behavioral and economic approaches in order to explain the process. The behavioral approach deals with the perception of phenomenon as a gradual process from the perspective of the executives behavior (JOHANSON and VAHLNE, 1977; HALLÉN and WIEDERSHEIM - PAUL, 1979; CZINKOTA, 1985). This phenomenon in permanent theoretical and managerial evolution made an opportunity to build this investigation, whose goal is to analyse the impact comes from organizational capabilities and the external environment on the international performance of exporting firms. For both, were used as theoretical basis two types of analysis for the comprehension of international performance: Strategic Management - Industrial Organization and Resource-Based View and International Businesses - Current Economic and Behavioral. It was made a cross-sectional survey-based explanatory research, including 150 exporting companies with operations in the Northeast of Brazil. A conceptual model was made with eight constructs and eight research hypotheses, representative of the effects of external factors on international performance. The data were processed using the Exploratory Factor Analysis and Structural Equation Modeling. The structural equations model was reespecified and estimated through the use of the maximum-likelihood method up to achieve adequated values of indexes of adjustment. As the main theoretical contribution, were identified organizational and physical resources which shows the importance of the management skills development, of the learning capability and capability to establish strategic alliances abroad. That because the knowledge, as the operational point of view as in its strategic application, offers to organization conditions of market positioning which can create opportunities sustainable competitive advantages and which impact the performance of international companies

Gutes Lernen und gute Lehre. Welchen Beitrag leistet die Qualitätssicherung. Beiträge zur 3. AQ Austria Jahrestagung 2015

Die Publikation zur AQ Austria Jahrestagung 2015 widmet sich dem Lernen und Lehren an Hochschulen und den vielfältigen Wandlungsprozessen durch die zunehmende biographische, soziale und kulturelle Diversität der Studierenden sowie elektronischen Medien. Student-centred Learning (SCL) gewinnt verstärkt an Bedeutung. Diese Wandlungsprozesse treffen nicht nur Studierende, Lehrende und die Hochschulen als Institutionen, auch die Qualitätssicherung in Studium und Lehre. Der Beitrag von Prof. Nacken zeigt auf, welche Chancen und Herausforderungen sich durch SCL in verschiedensten Bereichen ergeben. Er geht auf das Projekt „Studierende im Fokus der Exzellenz“, die Entwicklung der Charta für gute Lehre und aktuelle Trends und Probleme bei digitaler Lehre ein. Die studentische Perspektive zeigt Umsetzungsmöglichkeiten und Maßnahmen in Richtung Studierendenzentrierung auf. In den weiteren Beiträgen wird auf Didaktik und Qualitätssicherung, Determinanten studentischen Lernerfolgs, alternative Formen der Lehrevaluation und die Sichtbarmachung von non-formal und informell erworbenen Kompetenzen eingegangen und zwei beschäftigen sich mit Einsatzmöglichkeiten und Veränderungen durch neue Medien. Mit Beiträgen von: Nacken, Heribert; Hanft, Anke; Pichl, Elmar; Treml, Beate; Pellert, Ada; Künzel, Manfred; Haas, Lena; Martens, Thomas; Metzger, Christiane; Haag, Johann; Froschauer-Neuhauser, Elisabeth; Meyer Richli, Christine; Schulz, Ramona; Kämmerer, Frauke; Gornik, Elke A.; Freiberger, Diane; Birke, Barbara; Müller, Claude; Woschnack, Ute; Baumgartner, Alexander; Erlemann, Jennifer; Penßler-Beyer, Anja; Bergsmann, Evelyn; Weißemböck, Josef.
