This work proposes linear time strategies to optimally configure the phase shifts for reflective elements of an intelligent reflecting surface (IRS). Specifically, we show that binary beamforming can be solved in maximize received signal-to-noise ratio (SNR). For general K-ary beamforming, develop a approximation algorithm guarantees performance within constant fraction (1+\cos(\pi/K))/2 global...

This paper introduces a self-configuring middleware that manages the processes of context information acquisition and representation from smart closed environments, targeting the development of context aware applications. The environment context information is modeled using three sets: context resources, context actors and context policies. The context model artifacts are generated and administ...

This paper introduces a self-configuring middleware that manages the context information acquisition and representation processes targeting the development of context aware applications. The context information is represented in a programmatic manner, readable for the applications build on top of the middleware, using the RAP context model. An agent based context model management infrastructure...

Simultaneous localisation and categorization of objects in medical images, also referred to as object detection, is high clinical relevance because diagnostic decisions often depend on rating rather than e.g. pixels. For this task, the cumbersome iterative process method configuration constitutes a major research bottleneck. Recently, nnU-Net has tackled challenge for task image segmentation wi...

Configuring a security experiment can be tedious, involving many low level and repetitive configuration tasks. In order to make DETER’s capabilites accessible to users at all skill levels, we have designed and implemented a Security Experimentation EnviRonment (SEER) that provides security researchers the ability to create, plan, and iterate through a large range of experimental scenarios with ...

The goal of configuring a massive, complex multiagent system can be viewed as a distributed search problem in which each agent attempts to choose a correct configuration. This research presents a technique that can simultaneously function as the problem decomposition and solution aggregation components in such a distributed search environment. The method is tested in a number of large multi-age...

The performance of many envisioned applications in shortrange wireless ad hoc networking will critically rely on the promptness of the self-configuring network procedures. In that sense, a fundamental problem in ad hoc networks, is the device discovery and/or network initialization. In this paper we propose a randomized distributed algorithm for rapid device discovery during the deployment of a...
