In this work, we introduce OmniDrones, an efficient and flexible platform
tailored for reinforcement learning in drone control, built on Nvidia's
Omniverse Isaac Sim. It employs a bottom-up design approach that allows users
to easily design and experiment with various application scenarios on top of
GPU-parallelized si... | http://arxiv.org/abs/2309.12825v1 |
Inspired by the swarming or flocking of animal systems we study groups of
agents moving in unbounded 2D space. Individual trajectories derive from a
``bottom-up'' principle: individuals reorient to maximise their future path
entropy over environmental states. This can be seen as a proxy for keeping
options open, a prin... | http://arxiv.org/abs/2303.17906v2 |
Much research on Machine Learning testing relies on empirical studies that
evaluate and show their potential. However, in this context empirical results
are sensitive to a number of parameters that can adversely impact the results
of the experiments and potentially lead to wrong conclusions (Type I errors,
i.e., incorr... | http://arxiv.org/abs/2309.05381v1 |
The integrating sphere (IS) is an indispensable tool for measuring
transmission and scattering of materials and their colorimetry, as well as
other photometric tasks. The accuracy of its data depends critically on port
sizes used for measurement and control, usually defined by trial and error or
brute-force optical sim... | http://arxiv.org/abs/2309.15192v1 |
This is a review article on the quantum toroidal algebras, focusing on their
roles in various solvable structures of 2d conformal field theory,
supersymmetric gauge theory, and string theory. Using $\mathcal{W}$-algebras as
our starting point, we elucidate the interconnection of affine Yangians,
quantum toroidal algebr... | http://arxiv.org/abs/2309.07596v2 |
Joint Communication and Sensing (JCAS) is foreseen as one very distinctive
feature of the emerging 6G systems providing, in addition to fast end reliable
communication, the ability to obtain an accurate perception of the physical
environment. In this paper, we propose a JCAS algorithm that exploits a novel
beamforming ... | http://arxiv.org/abs/2309.06850v1 |
This letter investigates a fluid antenna system (FAS) where multiple ports
can be activated for signal combining for enhanced receiver performance. Given
$M$ ports at the FAS, the best $K$ ports out of the $M$ available ports are
selected before maximum ratio combining (MRC) is used to combine the received
signals from... | http://arxiv.org/abs/2309.07582v1 |
In the double-cone ignition inertial confinement fusion scheme, high density
DT fuel is rapidly heated with high-flux fast electrons, which are generated by
short and intense laser pulses. Gold cone target is usually used to shorten the
distance between the critical surface and the compressed high density DT core.
The ... | http://arxiv.org/abs/2305.19469v1 |
Electronic Health Record (EHR) has become an essential tool in the healthcare
ecosystem, providing authorized clinicians with patients' health-related
information for better treatment. While most developed countries are taking
advantage of EHRs to improve their healthcare system, it remains challenging in
developing co... | http://arxiv.org/abs/2302.01281v1 |
Robust header compression (ROHC), critically positioned between the network
and the MAC layers, plays an important role in modern wireless communication
systems for improving data efficiency. This work investigates bi-directional
ROHC (BD-ROHC) integrated with a novel architecture of reinforcement learning
(RL). We for... | http://arxiv.org/abs/2309.13291v1 |
A phase field approach is proposed to model the chemotaxis of Dictyostelium
discoideum. In this framework, motion is controlled by active forces as
determined by the Meinhardt model of chemical dynamics which is used to
simulate directional sensing during chemotaxis. Then, the movement of the cell
is achieved by the ph... | http://arxiv.org/abs/2302.14854v1 |
Information on archives from the 1950s of 15 astronomical observatories is
provided beginning with a list of correspondence and other information related
to astronomy of the Copenhagen University Observatory in the 1950s. The
Appendix contains information from the 14 other observatories about their
archives from those ... | http://arxiv.org/abs/2309.09746v1 |
Domain shift caused by, e.g., different geographical regions or acquisition
conditions is a common issue in machine learning for global scale satellite
image processing. A promising method to address this problem is domain
adaptation, where the training and the testing datasets are split into two or
multiple domains ac... | http://arxiv.org/abs/2309.11109v2 |
