A broadcast strategy for multiple access communication over slowly fading channels is introduced, in which the channel state information is known to only the receiver. In this strategy, the transmitters split their information streams into multiple independent information streams, each adapted to a specific actual channel realization. The major distinction between the proposed strategy and the ...

We use a block-fading model, with coherence interval T where M independent users simultaneously transmit to a single receiver equipped with N antennas in a flat-fading environment, where each user has sole access to one of M transmit antennas, and where nobody has any channel state information. The fading is described by an M × N complex-valued propagation matrix H, which remains constant for T...

This paper presents a planner that can solve the k-robust MAPF planner which is based on the Conflict-based search (CBS) (Sharon et al. 2015) MAPF solver. CBS does not explicitly search the n-agent state space. Instead, agents are associated with constraints of the form 〈ai, v, t〉, which would prohibit agent ai from occupying vertex v at time step t. A consistent path for agent ai is a path tha...

We present a novel approach to self-organisation of coordinated behaviour among multiple resource-sharing agents. We consider a hierarchical multi-agent system comprising multiple energy-dependent agents split into local neighbourhoods, each with a dedicated controller, and a centralised coordinator dealing only with the controllers. The coordinated behaviour is required in order to achieve a b...

In this paper, a new frequency domain approach towarb blind channel identification for multirate communication systems is described. Users are first separated based on different cyclic frequencies corresponding to their respective symbol rates, thereby resulting in a single-user (blind) identification scenario. The algorithm proposed in [3] is then used to estimate the channels for each rate. C...

The vertical transition energies for butadiene have been calculated using the CIS/6-3 1 1 (2+)G* theoretical model. The observed energies were satisfactorily reproduced. The charge distribution for each of the excited states was calculated so that the change from the ground-state distribution could be examined. The nature of the Rydberg states are discussed. Quantitative information on the degr...

Reinforcement Learning (RL) allows an agent to discover a suitable policy to achieve a goal. However, interesting problems for RL become complex extremely fast, as a function of the number of features that compose the state space. The proposed research is to decompose a core problem into tasks with only the features required to solve the task. The core agent then uses the reward for the task, w...

Introduction: Low frequency fluctuations in T2*-weighted MR images have been used to map functional connectivity (FC) in both humans and rats [1, 2, 3, 4]. Previous studies performed on rats have demonstrated the presence of networks within somatosensory as well as visual systems [2, 3, 4]. Although multiple slices were acquired in two of the studies [3, 4], those studies focused on functional ...
