Introduction: The straight skeleton of a polygon in 2D was first defined by Aichholzer et al. [2]. It is the geometric graph whose edges are the traces of vertices of shrinking mitered offset curves of the polygon, see Figure 1, left. Straight skeletons are a versatile tool in computational geometry and have found applications in diverse fields of industry and science. E.g., Tomoeda et al. use ...

Kalikow proved that the [T, T−1] transformation is not isomorphic to a Bernoulli shift [3]. We show that the scenery factor of the [T, T−1] transformation is not isomorphic to a Bernoulli shift. Moreover we show that it is not Kakutani equivalent to a Bernoulli shift.

Simulation is one of the effective tools for the assessment of waterway designing. The system constitution and procedure of waterway simulation are introduced, and key technologies of waterway simulation system are analyzed, including vessel dynamics modeling, vessel traffic flow modeling, waterway scenery modeling and assessment methods. Moreover, the design the simulation system of inland wat...

Let (Zn)n∈N be a d-dimensional random walk in random scenery, i.e., Zn = ∑n−1 k=0 Y (Sk) with (Sk)k∈N0 a random walk in Z d and (Y (z))z∈Zd an i.i.d. scenery, independent of the walk. The walker’s steps have mean zero and some finite exponential moments. We identify the speed and the rate of the logarithmic decay of P( 1 nZn > bn) for various choices of sequences (bn)n in [1,∞). Depending on (b...

For presenting virtual objects in a real space, mixed reality (MR) technique is very effective to simulate an overview of a scenery. In interior design, for instance, the coordinates of the arrangements and the colours of the items need to be determined based on various layout plans. We propose a new framework for interactively arranging and rendering virtual objects in real space by manipulati...
