Full Downlink Channel Reconstruction using Incomplete Uplink Channel Measurements in Massive MIMO networks

While more and more antennas are integrated into a single mobile user equipment to increase communication quality and throughput, the number of antennas used for transmission is commonly restricted due to the concerns on hardware complexity and energy consumption, making it impossible to achieve the maximum channel capacity. This paper investigates the problem of reconstructing the full downlink c

Weighting according to location in computer-assisted glaucoma visual field analysis

In recent years several aids for automated interpretation of visual field data have been suggested. We believed that incorporation of thorough knowledge of normal visual field variability would allow improvements in the performance of such aids since more attention would be paid to field results in areas with low physiological variability. Two visual field models for classification of fields in gl

Investigation of effects of intake temperature on low load limitations of methanol partially premixed combustion

Methanol has unique properties as a fuel, and partially premixed combustion has promising results with high engine efficiency and low emissions. Low load studies with methanol partially premixed combustion are scarce, and the effect of intake temperature on low load methanol partially premixed combustion still remains an intriguing question. This study aims to investigate the effect of intake temp

The yield of screening symptomatic contacts of multidrug-resistant tuberculosis cases at a tertiary hospital in Addis Ababa, Ethiopia.

BackgroundEarly detection and treatment of multidrug-resistant tuberculosis (MDR-TB, resistant to isoniazid and rifampicin) is an urgent global priority. Identifying and tracing close contacts of patients with MDR-TB could be a feasible strategy to achieve this goal. However, there is limited experience with contact tracing among patients with drug-resistant tuberculosis both globally and in Ethio

User Localization using Random Access Channel Signals in LTE Networks with Massive MIMO

Recent studies show that real-time precise user localization enables to deliver accurate beamforming in MIMO systems without the need for channel estimation. This paper presents new solutions for accurate user localization in massive MIMO LTE systems. A key novelty of the developed schemes is the ability to locate users during LTE's random access channel synchronization procedure before they are c

Properties of the CsI(Tl) detector elements of the CALIFA detector

In the RB experiment at FAIR, charged particles with energies up to 600 MeV and forward boosted -rays with energies up to 20 MeV need to be detected in scattering experiments. Calorimeters for nuclear physics experiments of this kind, using relativistic radioactive ion beams, require high energy resolution and high efficiency for simultaneous detection of strongly Doppler shifted -rays and high-en

Genetic correlations and their dependence on environmental similarity : insights from livestock data

Genetic correlations for a trait across environments are predicted to decrease as environments diverge. However, estimates ofgenetic correlations from natural populations are typically defined across a limited environmental range and prone to very largestandard errors, making it difficult to test this prediction. We address the importance of environmental distance on genetic cor-relations by employiGenetic correlations for a trait across environments are predicted to decrease as environments diverge.

Fake drugs that could kill are on the rise in Western countries – here’s why

Fake medicines – illegal and substandard pharmaceuticals – have until now largely been a problem in low and middle-income countries. Ranging from lifestyle products to lifesaving medicines, such products are now also on the rise in the Western world. The spread is concerning, as fake medicines can be completely ineffective or extremely toxic.

On imitation dynamics in potential population games

Imitation dynamics for population games are studied and their asymptotic properties analyzed. In the considered class of imitation dynamics - that encompass the replicator equation as well as other models previously considered in evolutionary biology - players have no global information about the game structure, and all they know is their own current utility and the one of fellow players contacted

Technical Committee on Networks and Communication Systems [Technical Activities]

The IEEE Control Systems Society (CSS) Technical Committee on Networks and Communication Systems (TC-NCS) focuses on areas that involve the interplay among networks, communication, and systems control. The TC is organized into eight working groups, Control of Network Systems, Information Networks and Control, Networked Sensing and Sensor Networks, Optimization and Game Theoretic Methods in Network
