Source-Channel Coding under Energy, Delay and Buffer Constraints [PDF]
, 2014 Source-channel coding for an energy limited wireless sensor node is investigated. The sensor node observes independent Gaussian source samples with variances changing over time slots and transmits to a destination over a flat fading channel.

Power Switching Protocol for Two-way Relaying Network under Hardware Impairments [PDF]
, 2015 In this paper, we analyze the impact of hardware impairments at relay node and source node (i.e. imperfect nodes) on network performance by evaluating outage probability based on the effective signal to noise and distortion ratio (SNDR).

A New Phase Sequence Exchanging Control Method for Reducing Impulse Current and Voltage
IEEE Access, 2019 Phase sequence exchanging technology (PSET) is a recently developed emergency control technology for out-of-step power systems. The PSET system does not satisfy the condition of synchronization however, and will produce impulse current and impact torque.

Study on Harmonic Impedance Estimation and Harmonic Contribution Evaluation Index
IEEE Access, 2020 Harmonic impedance estimation and suitable evaluation index selection are the key steps of harmonic contribution evaluation. Most of the traditional harmonic impedance estimation methods are only applicable to the scenario, where the background harmonic ...

Mutual Dependence between Sustainable Energy- and Sustainable Agriculture Policies-from the Global and European Perspective [PDF]
, 2012 Agriculture is one of the economic sectors to which the EU commitment to reduce emissions of greenhouse gases applies. Like any other economic sector, agriculture produces greenhouse gases and is a major source of the non- CO2 greenhouse gases methane ...

Energy Management Policies for Energy-Neutral Source-Channel Coding
, 2011 In cyber-physical systems where sensors measure the temporal evolution of a given phenomenon of interest and radio communication takes place over short distances, the energy spent for source acquisition and compression may be comparable with that used ...

Vacuum local and global electromagnetic self-energies for a point-like and an extended field source
, 2013 We consider the electric and magnetic energy densities (or equivalently field fluctuations) in the space around a point-like field source in its ground state, after having subtracted the spatially uniform zero-point energy terms, and discuss the problem ...

Young neutron stars with soft gamma ray emission and anomalous X-ray pulsar
, 2017 The observational properties of Soft Gamma Repeaters and Ano\-malous X-ray Pulsars (SGR/AXP) indicate to necessity of the energy source different from a rotational energy of a neutron star.
