Evolutionary Computation is used to automatically evolve small cell schedulers on a realistic simulation of a 4G-LTE heterogeneous cellular network. Evolved schedulers are then further augmented by human design to improve robustness. Extensive analysis of evolved solutions and their performance across a wide range of metrics reveals evolution has uncovered a new human-competitive scheduling technique which generalises well across cells of varying sizes. Furthermore, evolved methods are shown to conform to accepted scheduling frameworks without the evolutionary process being explicitly told the form of the desired solution. Evolved solutions are shown to outperform a human-engineered state-of-the-art benchmark by up to 50%. Finally, the approach is shown to be flexible in that tailored algorithms can be evolved for specific scenarios and corner cases, allowing network operators to create unique algorithms for different deployments, and to postpone the need for costly hardware upgrades.

MapReduce (MR) computing paradigm and its open source implementation Hadoop have become a de facto standard to process big data in a distributed environment. Initially, the Hadoop system was homogeneo...
Systematic reviews are increasingly using data from preclinical animal experiments in evidence networks. Further, there are ever-increasing efforts to automate aspects of the systematic review process...
A seminal work by Sheridan and Verplank (1978) depicted ten levels of automation, ranging from no automation to an automation that acts completely autonomously without human support. These levels of a...
Previous studies have observed a positive association between automation risk and employment loss. Based on the job insecurity-health risk hypothesis, greater exposure to automation risk could also be...
Lip augmentation procedures with hyaluronic acid dermal fillers have become increasingly popular worldwide because full lips are often considered beautiful and youthful. The goal of a lip augmentation...
The proposed study design is a randomized controlled trial, split mouth design, to compare the two different vertical augmentation procedures: Titanium mesh (Ti-mesh) technique and Guided ...
The investigators plan to use functional neuroimaging (fMRI) to understand the brain systems affected when hypnosis and hypnotic analgesia are augmented with repetitive transcranial magnet...
The purpose of this study is to (1) compare the response of civilians with Posttraumatic Stress Disorder(PTSD) currently receiving sertraline without an optimal response to risperidone aug...
This study evaluates the potential negative effect of cement augmentation in the femoral head on viability of the head. Half of the participants will have the standard intramedullary nail ...
The study will look at real-times adhernce monitoring with Portal-724 MEMS cap. It integrates medication bottle, Smart Cap, Pill Dispenser, Embedded Computer, Embedded Cellular Modem and T...
Communications networks connecting various hardware devices together within or between buildings by means of a continuous cable or voice data telephone system.
Communications via an interactive conference between two or more participants at different sites, using computer networks (COMPUTER COMMUNICATION NETWORKS) or other telecommunication links to transmit audio, video, and data.
Communications using an active or passive satellite to extend the range of radio, television, or other electronic transmission by returning signals to earth from an orbiting satellite.
The use of automatic machines or processing devices in libraries. The automation may be applied to library administrative activities, office procedures, and delivery of library services to users.
An approach, process, or methodology which emphasizes credible evidence and the best available scientific knowledge, judiciously integrated to achieve the best possible outcomes in structural design. For example, the design of a new OUTPATIENT CLINIC might incorporate a review of published research on outpatient clinic design, decisions on similar past projects, along with interviews with staff and consumers.
Standard antiretroviral therapy (ART) consists of the combination of at least three antiretroviral (ARV) drugs to maximally suppress the HIV virus and stop the progression of HIV disease. Huge reductions have been seen in rates of death and suffering whe...
