We consider a team of k identical, oblivious, and semi-synchronous mobile robots that are able to sense (i.e., view) their environment, yet are unable to communicate, and evolve on a constrained path. Previous results in this weak scenario show that initial symmetry yields high lower bounds when problems are to be solved by deterministic robots. In this paper, we initiate research on probabilis...

Let D be a connected region inside a simple polygon, P . We define the angle hull of D, AH(D), to be the set of all points in P that can see two points of D at a right angle. We show that the perimeter of AH(D) cannot exceed in length the perimeter of D by more than a factor of 2. This upper bound is tight. Our result can be generalized to angles different from 90◦, and to settings where region...

We propose an abstract framework for Design Space Exploration (DSE) in the context of model-based embedded system development. The goal is to enable the integration of a set of concrete DSE methods addressing different system characteristics and design goals while still having a common understanding of design artifacts.

results researchers have reported that mirnas can repress the expression of important cancer-related genes and might be helpful in the diagnosis and treatment of cancer. during the past two decades, numerous studies have shown that mirnas play an essential role in inhibiting hcc via several different pathways. deregulated mirnas may contribute to carcinogenesis, indicating that mirnas can act a...

Abstract. The site selection procedure for a high-level radioactive waste repository in Germany is based on the Repository Site Selection Act (StandAG, 2017), which comprises three phases. In phase 2 Federal Company Radioactive Waste Disposal (BGE) will conduct surface exploration. Based exploratory findings, further developed preliminary safety analyses, common requirements and criteria, poten...

Examining the relevance of 'animal personality' involves linking consistent among- and within-individual behavioural variation to fitness in the wild. Studies aiming to do this typically assay personality in captivity and rely on the assumption that measures of traits in the laboratory reflect their expression in nature. We examined this rarely tested assumption by comparing laboratory and fiel...

The multi-robot exploration problem is to explore an unknown graph of size n and depth d with k robots starting from the same node. For known graphs a traversal of all nodes takes at most O(d + n/k) steps. The ratio between the time until cooperating robots explore an unknown graph and the optimal traversal of a known graph is called the competitive exploration time ratio. It is known that for ...
