The German Information Systems Perspective

This paper provides an overview of the development of the Information Systems (IS) discipline in German universities for French readers. First, we briefly introduce particularities of the German university system which influence the IS discipline. Then we sketch the historic development of the IS discipline in Germany and describe the discipline\u27s actual associations and most important institutions. After deliberating prevailing research topics we give a survey of the course syllabus. Finally we briefly assess the future of the German IS discipline

Acreage, Residency and Excess-Land Sale: Striking a Balance between Modern Agriculture and Historic Water Policy

This comment examines acreage and residency limitations on federally subsidized water. The first issue addressed by the author is whether the present 160-acre irrigation entitlement should be raised to conform with modern agriculture. The second issue addressed by the author is the requirement that any purchaser of excess land would be required to reside within fifty miles of the land. The author concludes by examining current proposals for sale of excess land owned by persons not meeting the acreage limitation and by non-residents as well as legislation recommending government purchase of excess land, sale to would-be buyers lacking money and financing, and federally guaranteed loans to buyers

An Overview of the Potential of Solar Radiation as an Energy Source for Residential Heating in Northern Utah

Americans across the nation are showing an increased awareness of the problems caused by the rapid and uncontrolled growth our country has undergone over the last fifty years. It is apparent to most that we can no longer abuse our natural resources as if they were inexhaustable. In the last few years, there has been a specific concern for prices, consumption, and energy conservation. These real concerns are moving us towards a reconsideration of our living habits that will certainly affect the future of residential planning and site design

Elimination of Domain Boundaries Accelerates Diffusion in MOFs by an Order of Magnitude: Monolithic Metal‐Organic Framework Thin Films Epitaxially Grown on Si(111) Substrates

Many properties of the emerging class of metal-organic frameworks (MOFs) depend crucially on defect concentrations, as in case of other solids. In order to provide reference systems with nearly perfect structure and low defect density, a procedure to grow MOFs epitaxially on cm-sized Si(111) single crystals is developed. The crystalline metal-organic thin films are in high registry with the substrate\u27s crystal lattice, as demonstrated by synchrotron-based grazing incidence X-ray diffraction (GI-XRD) experiments. The corresponding reduction of MOF defect density is shown to have striking effects on the properties of these porous frameworks. The most pronounced difference concerns mass transport. An increase in the diffusion coefficient of guest molecules by one order of magnitude relative to the same MOF materials with normal defect densities is observed

Searching with Consistent Prioritization for Multi-Agent Path Finding

We study prioritized planning for Multi-Agent Path Finding (MAPF). Existing prioritized MAPF algorithms depend on rule-of-thumb heuristics and random assignment to determine a fixed total priority ordering of all agents a priori. We instead explore the space of all possible partial priority orderings as part of a novel systematic and conflict-driven combinatorial search framework. In a variety of empirical comparisons, we demonstrate state-of-the-art solution qualities and success rates, often with similar runtimes to existing algorithms. We also develop new theoretical results that explore the limitations of prioritized planning, in terms of completeness and optimality, for the first time.Comment: AAAI 201
