Geographic applications of ERTS-1 data to landscape change

The analysis of landscape change requires large area coverage on a periodic basis in order to analyze aggregate changes over an extended period of time. To date, only the ERTS program can provide this capability. Three avenues of experimentation and analysis are being used in the investigation: (1) a multi-scale sampling procedure utilizing aircraft imagery for ground truth and control; (2) a densitometric and computer analytical experiment for the analysis of gray tone signatures, comparisons and ultimately for landscape change detection and monitoring; and (3) an ERTS image enhancement procedure for the detection and analysis of photomorphic regions

Institutional change in the German wage bargaining system: The role of big companies

Despite the emergence of new production systems, Europeanization and economic internationalization, the national arrangements of wage bargaining systems have not been eroded. The paper highlights the factors that counteract the pressures for a straightforward decentralization with reference to Germany. Firstly, the maintenance of peaceful labour relations is a major advantage for big companies in centralized wage bargaining systems. Secondly, big companies have been able to achieve labour cost control and the differentiation of working conditions by drawing up pacts for employment and competitiveness at the company level. Thirdly, they have succeeded in introducing a higher degree of flexibility into the collective agreement framework. The main argument will be that institutional change has taken other forms than expected. Whereas the formal institutional setting has remained relatively stable, the functioning of the German wage bargaining system has changed. -- Trotz der Verbreitung neuer Produktionssysteme, der Europäisierung und der wirtschaftlichen Internationalisierung sind nationale Tarifverhandlungssysteme in den meisten Ländern stabil geblieben. Dieses Working Paper hebt am Beispiel Deutschlands die Faktoren hervor, die dem Dezentralisierungsdruck entgegen wirken. Für Großunternehmen ist auch unter veränderten Bedingungen die Vermeidung von Konflikten einer der Hauptvorteile zentraler Tarifverhandlungssysteme. In dem gegebenen institutionellen Rahmen haben Unternehmen Möglichkeiten gefunden, über Standortsicherungsvereinbarungen auf Unternehmensebene die Arbeitsorganisation zu flexibilisieren und Arbeitskosten zu senken. Zudem konnten sie Tarifverträge flexibler gestalten und Öffnungsmöglichkeiten einfügen. Als Ergebnis wird festgehalten, dass institutionelle Veränderungen andere Formen angenommen haben als erwartet. Während die formalen institutionellen Rahmenbedingungen verhältnismäßig stabil geblieben sind, hat sich die Funktionsweise des deutschen Tarifverhandlungssystems verändert.

The verification of LANDSAT data in the geographical analysis of wetlands in west Tennessee

The reliability of LANDSAT imagery as a medium for identifying, delimiting, monitoring, measuring, and mapping wetlands in west Tennessee was assessed to verify LANDSAT as an accurate, efficient cartographic tool that could be employed by a wide range of users to study wetland dynamics. The verification procedure was based on the visual interpretation and measurement of multispectral imagery. The accuracy testing procedure was predicated on surrogate ground truth data gleaned from medium altitude imagery of the wetlands. Fourteen sites or case study areas were selected from individual 9 x 9 inch photo frames on the aerial photography. These sites were then used as data control calibration parameters for assessing the cartography accuracy of the LANDSAT imagery. An analysis of results obtained from the verification tests indicated that 1:250,000 scale LANDSAT data were the most reliable scale of imagery for visually mapping and measuring wetlands using the area grid technique. The mean areal percentage of accuracy was 93.54 percent (real) and 96.93 percent (absolute). As a test of accuracy, the LANDSAT 1:250,000 scale overall wetland measurements were compared with an area cell mensuration of the swamplands from 1:130,000 scale color infrared U-2 aircraft imagery. The comparative totals substantiated the results from the LANDSAT verification procedure

Pedestrian Prediction by Planning using Deep Neural Networks

Accurate traffic participant prediction is the prerequisite for collision avoidance of autonomous vehicles. In this work, we predict pedestrians by emulating their own motion planning. From online observations, we infer a mixture density function for possible destinations. We use this result as the goal states of a planning stage that performs motion prediction based on common behavior patterns. The entire system is modeled as one monolithic neural network and trained via inverse reinforcement learning. Experimental validation on real world data shows the system's ability to predict both, destinations and trajectories accurately
