Ein Ziel der Arbeit war die Entwicklung eines Verfahrens zur 3D-Positionierung auf Basis elektrooptischer Pseudostreckenmessung. Ein zweites Ziel war die Entwicklung eines Reflexgoniometers zur zweiachsigen Winkelmessung. Im Rahmen der Arbeit wurden die Grundlagen zur instrumentellen Umsetzung beider Verfahren erarbeitet, die Genauigkeitspotentiale ermittelt und mögliche Anwendungen für die einzelnen Schlüsseltechnologien und deren Kombination abgeleitet. In einer Prototyp-Entwicklung wurden Vorschläge für die wesentlichen Funktionselemente des räumlichen Weg- bzw. Winkelmesssystems gemacht. Hierzu gehören das kardanisch aufgehängte Etalon, die temperaturstabilisierte Laseroptik und die temperaturkalibrierte CCD der Winkelmesseinheit (Reflexgoniometer), die Systeme zur Erzeugung und Detektion ultrakurzer Laserpulse, eine elastische Optik, Möglichkeiten zur Formung des transversalen Strahlprofils, das TCSPC-System und die zur Auswertung und Kalibrierung notwendigen Algorithmen, wie z.B. die Autokollimation eines Lasers. ("Veröffentlicht von der Deutschen Geodätischen Kommission Reihe C (Dissertationen) unter der Nummer C 614 (München 2008; ISBN 3 7696 5053 0; 2; 144 S.") / One goal of the thesis was the development of a method for three-dimensional positioning based on electro-optical measurement of pseudo ranges. Another goal was the development of a reflex goniometer for biaxial angle measurement. Within the scope of this thesis the basics for the instrumental realisation of both methods were developed, the accuracy potentials were determined and possible applications for the separate key technologies and their combination were deduced. In a prototype development proposals were made for the main functional elements of the spatial distance and angle measurement systems. These include the gimbal mounted etalon, the temperature stabilised laser optics and the temperature calibrated CCD of the angle measurement device (reflex goniometer), the systems for creation and detection of ultrashort laser pulses, an elastic optical device, possibilities of transversal beam shaping, the TCSPC system and the algorithms which are necessary for analysis and calibration, e.g. the autocollimation of a laser.

Social Impact Assessment (SIA) is the process of analyzing, monitoring and managing the social effects of planned or implemented development interventions. The primary purpose of SIA is to bring about a sustainable and equitable biophysical and social environment. SIA is a prerequisite in FAO and World Bank aided projects which cover sectors of mining, agriculture, fishery, dams and transportation. In forestry it has the great potential of enhancing sustainable forest management, taking into account rural development objectives and local needs. SIA can be applied before and after the implementation of projects and programs. In the context of recent policy changes in China, the Natural Forest Protection Program (NFPP) has been implemented in a “top-down” process from 1998 to 2010. A large part of the forests on main river basins in Western regions are being conserved with severe restrictions for commercial use. The social effects of the NFPP are still debatable, indicating a need for conducting a SIA of the NFPP using a systematic conceptual approach. Objectives of the research are: (1) To understand how and to what extent the NFPP affected the local forest-dependent communities and their households; (2) To identify the local strategies currently used to cope up with the impacts; and (3) To develop the optimal strategies likely supported for a better harmonization between livelihood and the NFPP implementation in different regional contexts. The empirical research is approached through quantitative and qualitative social research methods for data collection and analysis. For the case studies, four villages with a total number of 175 respondents were selected for field surveys where questionnaires, interviews and group discussions were employed. The research findings indicate that, the NFPP has significant impacts on the population characteristics, institutional arrangements and infrastructure and public services at the community level and at household level, the income derivation, expenditure, labour time distribution, perceptions on public health/safety and changing values of forests perceived by individuals. The research reveals that, synthesizing de facto impacts of the NFPP makes potential negative social impacts predictable. The policy-makers and project teams implementing the NFPP should be aware that, the NFPP results in dynamic change processes which include the de facto and potential impacts as well as the influence factors; among these, contribution of strategies derived from local communities and households as the spontaneous reactions to cope with the NFPP impacts should be taken into consideration. Recommendations are given referring to a better implementation of the NFPP and the need for future researches concerning the SIA for sustainable forest management in different regional contexts. / Social Impact Assessment (SIA) ist ein Prozess, der Analyse, Monitoring und Bewältigung der sozialen Effekte geplanter oder durchgeführter Entwicklungsinterventionen umfasst. Das Hauptanliegen von SIA ist, eine nachhaltige und gerechte biophysische und soziale Umwelt zu schaffen. SIA ist für Projekte der FAO und der Weltbank in den Sektoren Bergbau, Landwirtschaft, Fischerei, Talsperren und Transport eine Grundvoraussetzung. Für die Forstwirtschaft ergibt sich daraus das Potenzial, nachhaltige Waldbewirtschaftung zu stärken und dabei die Ziele ländlicher Entwicklung und lokale Erfordernisse zu berücksichtigen. SIA kann vor und nach der Durchführung von Projekten und Programmen angewendet werden. Im Zusammenhang mit den aktuellen politischen Veränderungen in China wird das Natural Forest Protection Program (NFPP) im Zeitraum von 1998-2010 nach dem top-down-Verfahren durchgeführt. Die sozialen Auswirkungen des NFPP sind noch immer umstritten. Das unterstreicht die Notwendigkeit der SIA unter Anwendung einer systematischen konzeptionellen Herangehensweise. Ein besonders kritischer Faktor dabei ist, dass ein erheblicher Anteil der Wälder in den Wassereinzugsgebieten wichtiger Flussläufe in den westlichen Regionen durch strikte Einschränkungen der kommerziellen Nutzung geschützt wurden. Die Ziele der Forschung sind: (1) Aufzeigen wie und in welchem Ausmaß das NFPP die örtlichen waldabhängigen Gemeinden und ihre Haushalte beeinflusst hat; (2) Identifizieren lokal entwickelter und angewandter Strategien, um die Auswirkungen des NFPP zu bewältigen; und (3) Entwickeln optimaler Strategien für eine bessere Harmonisierung der Lebensgrundlagen mit der Umsetzung des NFPP in unterschiedlichen regionalen Kontexten. Die empirische soziale Forschung bedient sich quantitativer und qualitativer Methoden zur Datensammlung und Datenanalyse. Für die Fallstudie wurden vier Dörfer mit insgesamt 175 Befragten ausgewählt. Bei der Primärdatenerhebung kamen Fragebögen, Interviews und Gruppendiskussionen zur Anwendung. Die Forschungsergebnisse zeigen, dass das NFPP signifikanten Einfluss ausübt auf Größe und Anteil armer Bevölkerung, auf institutionelle Rahmenbedingungen, die Infrastruktur und den öffentlichen Dienstleistungssektor auf Gemeindeebene. Auf Haushaltsebene wurde signifikanter einfluss nachgewiesen für die Generierung von Einkommen, die Ausgaben, die Arbeitszeitverteilung, die Vorstellungen über Gesundheitswesen und Sicherheit als auch auf die Wahrnehmung der sich verändernden Werte des Waldes. Es wird ersichtlich, dass durch Zusammenführen der de facto-Auswirkungen des NFPP potenzielle negative soziale Einflüsse vorhersagbar werden. Entscheidungsträger und Projektteams sollten sich darüber bewusst werden, dass das NFPP zu dynamischen Veränderungsprozessen führt, welche die de facto- und potentiellen Auswirkungen sowie die Einflussfaktoren betreffen. Dies schließt den Beitrag der lokal entwickelten Strategien ein. Empfehlungen betreffen die bessere Umsetzung des NFPP sowie die Notwendigkeit weiterer Forschung hinsichtlich der SIA im Zusammenhang nachhaltiger Waldbewirtschaftung in verschiedenen regionalen Kontexten.

The concept of outlier detection by statistical hypothesis testing in geodesy is briefly reviewed. The performance of such tests can only be measured or optimized with respect to a proper alternative hypothesis. Firstly, we discuss the important question whether gross errors should be treated as non-random quantities or as random variables. In the first case, the alternative hypothesis must be based on the common mean shift model, while in the second case, the variance inflation model is appropriate. Secondly, we review possible formulations of alternative hypotheses (inherent, deterministic, slippage, mixture) and discuss their implications. As measures of optimality of an outlier detection, we propose the premium and protection, which are briefly reviewed. Finally, we work out a practical example: the fit of a straight line. It demonstrates the impact of the choice of an alternative hypothesis for outlier detection. / Das Konzept der Ausreißererkennung durch statistische Hypothesentests in der Geodäsie wird kurz überblickt. Die Leistungsfähigkeit solch eines Tests kann nur gemessen oder optimiert werden in Bezug auf eine geeignete Alternativhypothese. Als erstes diskutieren wir die wichtige Frage, ob grobe Fehler als nicht-zufällige oder zufällige Größen behandelt werden sollten. Im ersten Fall muss die Alternativhypothese auf das Mean-Shift-Modell gegründet werden, im zweiten Fall ist das Variance-Inflation-Modell passend. Als zweites stellen wir mögliche Formulierungen von Alternativhypothesen zusammen und diskutieren ihre Implikationen. Als Optimalitätsmaß schlagen wir das Premium-Protection-Maß vor, welches kurz überblickt wird. Schließlich arbeiten wir ein praktisches Beispiel aus: Die Anpassung einer ausgleichenden Gerade. Es zeigt die Auswirkung der Wahl einer Alternativhypothese für die Ausreißererkennung.

The major aims of this paper are to present how we can improve the students understanding and involvement in mathematics by using a programming/graphic calculator. I will use differentials as examples such as differentiation ,integrals and differential equations, creating lines of slopes for differential equation of the type y’= f(x,y) . Find the solution of some differential equations by using regression and create the graph connected to the differential equation. As we have different approaches to solving a problem, it is a hope the students interest in mathematics will improve. The tools used will be programming, graphic commands as plot, f-line, etc. One goal is also to show how we can create small programs solving problems in mathematics. For many students this will be a stepping stone for further work with programming. The programs used can be copied using the program FA 124 that can be downloaded from Casios homepages. On request I can send you the programs.

The major aims of this paper are to present how we can improve the students understanding and involvement in mathematics by using a programming/graphic calculator. I will use differentials as examples such as differentiation ,integrals and differential equations, creating lines of slopes for differential equation of the type y’= f(x,y) . Find the solution of some differential equations by using regression and create the graph connected to the differential equation. As we have different approaches to solving a problem, it is a hope the students interest in mathematics will improve. The tools used will be programming, graphic commands as plot, f-line, etc. One goal is also to show how we can create small programs solving problems in mathematics. For many students this will be a stepping stone for further work with programming. The programs used can be copied using the program FA 124 that can be downloaded from Casios homepages. On request I can send you the programs.
