Multi-robot systems present unique challenges for the experimenter. There are three key components for conducting successful multi-robot experiments: 1) Defining platformindependent metrics for evaluating algorithm performance, 2) determining the ground truth of the robot’s physical configuration and network connectivity, and 3) designing a usable system, with centralized data collection and ha...

Scientists often run experiments to distinguish competing theories. This requires patience, rigor, and ingenuity—there is often a large space of possible experiments one could run. But we need not comb this space by hand—if we represent our theories as formal models and explicitly declare the space of experiments, we can automate the search for good experiments, looking for those with high expe...

This paper uses prediction error identification to distinguish control-relevant system changes in closed-loop operation from variations in disturbance characteristics. The approach consists of a hypothesis test to verify whether an identified model of the true system lies in a set containing all models that exhibit adequate closed-loop performance. To increase the detection probability, i.e. th...

A taxonomy of requirements for advanced experiment control systems (ECS) is derived from basic and application-oriented research scopes independently from implementation considerations. Every demand within the taxonomy is described in detail with an emphasis to its potential impact on the ECS-design. On top of the Java 2 Enterprise Edition architecture for web-enabled scalable business applicat...

The local search with orthogonal design of experiment in its neighborhood determination (ODLS) outperforms the local search with the conventional neighborhood when the objective function includes noise. This models practical optimization problems that contains uncontrolled or unobserved variables. ODLS is robust and e cient since it shares all evaluations for direction determination of each var...

The utilization of frequency spectrum for space-to-ground communications applications has generally progressed from the lowest available bands capable of supporting transmission through the atmosphere to the higher bands, which have required research and technological advancement to implement. As communications needs increase and the available spectrum in the microwave frequency bands (3–30 GHz...

The allocation of facilities and customers is a key problem in the design of supply chains of companies. In this paper, this issue is approached by partitioning the territory in areas where the distribution points are allocated. The demand is modelled through a set of continuous functions based on the population density of the geographic units of the territory. Because the partitioning problem ...

This study explored tradeoffs between two research methodologies – scientifically based research and design experiments. We conducted this exploration through a case study of one teacher's four-year implementation of a multimedia learning environment called Astronomy Village®. During the first year of her implementation, she participated in the scientifically based summative evaluation of Astro...
