Altering the time base required physically changing the ramp generator. In this article a new method of generating the sweep deflection ramps is presented that permits changing the sweep rate by computer control without replacing the ramp generator. A logic level signal can now be used to change sweep rates without the need for invasive component changes. This new development permits fast and e...

in the present work, b-zsm-5 zeolite membranes were synthesized on porous tubular α-alumina supports by several subsequence in situ crystallization hydrothermal treatments. the tio2- bohmite and ɣ- alumina intermediate layers were applied to improve the lattice matching between zeolite layer and the support. the uniform membrane intermediate layers with low permeation resistance were prepared o...

Given a set images of the same scene, the goal of video-based rendering methods is tocompute new views of this scene from new viewpoints.In this thesis,we focus on the Plane Sweep method. This method divides space in parallelplanes and each point of each plane is processed independently in order to know if it lies onthe surface of an object of the scene.Our main contribu...

We present the first release of the C++ libraries of the Exacus project of the Max-PlanckInstitut für Informatik. We explain the structure of the libraries and the software design for the numerics library and the sweep-line algorithm library in more detail.

We present a new polygon decomposition problem, the anchored area partition problem, which has applications to a multiple-robot terrain-covering problem. This problem concerns dividing a given polygon P into n polygonal pieces, each of a speciied area and each containing a certain point (site) on its boundary. We rst present the algorithm for the case when P is convex and contains no holes. The...

When we search from a huge amount of documents, we often specify several keywords to narrow the result of the search. Though the searched documents contain all keywords, positions of the keywords are usually not considered. As the result, the search result contains some meaningless documents. In this paper, we propose two algorithms for nding documents in which all given keywords appear in neig...

Object-based systems present particular challenges for state space exploration. Objects can be dynamically created and discarded, and can be referenced via object identifiers. Consistent relabelling of object identifiers in a state leads to a state that is superficially different but behaviourally equivalent to the original. Similarly, object-based systems can include garbage which has no effec...

Two novel applications of the plane sweep paradigm are demonstrated, namely, for the computation of extended viewsheds on gridded DEMs and for class interval selection on TIN-based DEMs. In both cases, the e ciency of the plane sweep algorithm is signi cantly better than a straightforward approach. The algorithms are presented by rst giving the plane sweep method as a general approach that requ...

FeNi binary nanowires with gradient composition are fabricated by the electrodeposition method. The energy dispersive spec-trometer line-sweep results show that the composition changes gradually along the wire axis. The gradient FeNi nanowires exhibit polycrystalline and crystal twinning at different areas along the nanowire axis, with a textured face-centered cubic structure. The static and dy...

In some more complicated tasks the use of multiple robots can be advantageous, as there are some tasks that are just not achievable by a single robot. Teams of cooperating robots can accomplish more and faster than individual robots, as is the case in the intruder detection problem. Here, two off-line algorithms are presented for intruder detection in a known environment. In the first approach,...
