On Long Memory Origins and Forecast Horizons
J. Eduardo Vera-Valdés
Most long memory forecasting studies assume that the memory is generated by the fractional difference operator. We argue that the most cited theoretical arguments for the presence…
Localised Wannier functions in metallic systems
Horia Cornean, David Gontier, Antoine Levitt +1
The existence and construction of exponentially localised Wannier functions for insulators is a well-studied problem. In comparison, the case of metallic systems has been much less…
Predicting the dissolution kinetics of silicate glasses using machine learning
N. M. Anoop Krishnan, Sujith Mangalathu, Morten M. Smedskjaer +3
Predicting the dissolution rates of silicate glasses in aqueous conditions is a complex task as the underlying mechanism(s) remain poorly understood and the dissolution kinetics ca…
Analysis of Latency and MAC-layer Performance for Class A LoRaWAN
R. B. Sørensen, D. M. Kim, J. J. Nielsen +1
We propose analytical models that allow us to investigate the performance of long range wide area network (LoRaWAN) uplink in terms of latency, collision rate, and throughput under…
Quantum spill out in few-nanometer metal gaps: Effect on gap plasmons and reflectance from ultrasharp groove arrays
Enok J. H Skjølstrup, Thomas Søndergaard, Thomas G. Pedersen
Plasmons in ultranarrow metal gaps are highly sensitive to the electron density profile at the metal surfaces. Using a fully quantum mechanical approach, we study the effects of el…
An Enhanced Access Reservation Protocol with a Partial Preamble Transmission Mechanism in NB-IoT Systems
Taehoon Kim, Dong Min Kim, Nuno Pratas +2
In this letter, we propose an enhanced Access Reservation Protocol (ARP) with a partial preamble transmission (PPT) mechanism for the narrow band Internet of Things (NB-IoT) system…
A New Transferable Interatomic Potential for Molecular Dynamics Simulations of Borosilicate Glasses
Mengyi Wang, N. M. Anoop Krishnan, Bu Wang +3
Borosilicate glasses are traditionally challenging to model using atomic scale simulations due to the composition and thermal history dependence of the coordination state of B atom…
Resolvent expansion for the Schrödinger operator on a graph with infinite rays
Kenichi Ito, Arne Jensen
We consider the Schrödinger operator on a combinatorial graph consisting of a finite graph and a finite number of discrete half-lines, all jointed together, and compute an asymptot…
Utilizing Domain Knowledge in End-to-End Audio Processing
Tycho Max Sylvester Tax, Jose Luis Diez Antich, Hendrik Purwins +1
End-to-end neural network based approaches to audio modelling are generally outperformed by models trained on high-level data representations. In this paper we present preliminary…
Timed Comparisons of Semi-Markov Processes
Mathias Ruggaard Pedersen, Nathanaël Fijalkow, Giorgio Bacci +2
Semi-Markov processes are Markovian processes in which the firing time of the transitions is modelled by probabilistic distributions over positive reals interpreted as the probabil…
Reliable Video Streaming over mmWave with Multi Connectivity and Network Coding
Matteo Drago, Tommy Azzino, Michele Polese +2
The next generation of multimedia applications will require the telecommunication networks to support a higher bitrate than today, in order to deliver virtual reality and ultra-hig…
Peierls' substitution for low lying spectral energy windows
Horia D. Cornean, Bernard Helffer, Radu Purice
We consider a magnetic Schrödinger operator perturbed by a weak magnetic field which slowly varies around a positive mean. In a previous paper we proved the appearance of a `L…
New binary and ternary LCD codes
Carlos Galindo, Olav Geil, Fernando Hernando +1
LCD codes are linear codes with important cryptographic applications. Recently, a method has been presented to transform any linear code into an LCD code with the same parameters w…
Cramér-Rao Bounds for Blind Multichannel Estimation
Elisabeth de Carvalho, Dirk Slock
In some estimation problems, not all the parameters can be identified, which results in singularity of the Fisher Information Matrix (FIM). The Cramér-Rao Bound (CRB), which is the…
Linear and nonlinear optical response of crystals using length and velocity gauges: Effect of basis truncation
Alireza Taghizadeh, F. Hipolito, T. G. Pedersen
We study the effects of a truncated band structure on the linear and nonlinear optical response of crystals using four methods. These are constructed by (i) choosing either length…
Time Series Management Systems: A Survey
Søren Kejser Jensen, Torben Bach Pedersen, Christian Thomsen
The collection of time series data increases as more monitoring and automation are being deployed. These deployments range in scale from an Internet of things (IoT) device located…
Conditional Generative Adversarial Networks for Speech Enhancement and Noise-Robust Speaker Verification
Daniel Michelsanti, Zheng-Hua Tan
Improving speech system performance in noisy environments remains a challenging task, and speech enhancement (SE) is one of the effective techniques to solve the problem. Motivated…
Using Session Types for Reasoning About Boundedness in the Pi-Calculus
Hans Hüttel
The classes of depth-bounded and name-bounded processes are fragments of the pi-calculus for which some of the decision problems that are undecidable for the full calculus become d…
Response to 'Burden of proof: A comprehensive review of the feasibility of 100% renewable-electricity systems'
T. W. Brown, T. Bischof-Niemz, K. Blok +3
A recent article 'Burden of proof: A comprehensive review of the feasibility of 100% renewable-electricity systems' claims that many studies of 100% renewable electricity systems d…
Joint Separation and Denoising of Noisy Multi-talker Speech using Recurrent Neural Networks and Permutation Invariant Training
Morten Kolbæk, Dong Yu, Zheng-Hua Tan +1
In this paper we propose to use utterance-level Permutation Invariant Training (uPIT) for speaker independent multi-talker speech separation and denoising, simultaneously. Specific…
Optical third harmonic generation in black phosphorus
F. Hipolito, T. G. Pedersen
We present a calculation of Third Harmonic Generation (THG) for two-band systems using the length gauge that avoids unphysical divergences otherwise present in the evaluation of th…
On parabolic final value problems and well-posedness
Ann-Eva Christensen, Jon Johnsen
We prove that a large class of parabolic final value problems is well posed.This results via explicit Hilbert spaces that characterise the data yielding existence, uniqueness and s…
Enabling Self-aware Smart Buildings by Augmented Reality
Muhammad Aftab, Sid Chi-Kin Chau, Majid Khonji
Conventional HVAC control systems are usually incognizant of the physical structures and materials of buildings. These systems merely follow pre-set HVAC control logic based on abs…
