This paper deals with estimation of the waveform of a single event-related potential, sERP. An additive noise model is used for the measured signal and the SNR of the disturbed sERP is approximately 0 dB. The sERP is described by a series expansion where the basis functions are damped sinusoids. The fundamental basis function is estimated by the least squares Prony method, derived for colored nois
The adaptive Least Absolute Shrinkage and Selection Operator (aLASSO) method is an algorithm for simultaneous model selection and parameter estimation with oracle properties. In this work we derive an adaptive LASSO type estimator for diffusion driven stochastic differential equation under weak conditions, specifically that the algorithm does not rely on high frequency properties.All conditional m
This paper deals with the issue of former border railway stations (FBRSs) in Poland in the context of their problematic heritage. Since the creation of those borders coincided with the development of the railway network in the 19th century, the FBRSs, now deprived of their past function, remain scattered throughout the landscape as confusing components of a troubled history in an even more confusi
A rigid-body model of a finger interacting with a trackball is considered. The proposed system is a suitable candidate for studying trajectory generation when interaction plays an important role, such as in assembly and manipulation tasks. The mathematical model consists of a ball with a spherical joint constraint, a finger with three degrees of freedom, and the Coulomb friction model. From first
Consider a pattern graph H with l edges, and a host graph G which may contain several occurrences of H. In [15], we claimed that the time complexity of the problems of finding an occurrence of H (if any) in G as well as that of the decision version of the problem are within a multiplicative factor O˜(l3) of the time complexity for the corresponding problem, where the host graph is guaranteed to co
The minimum and the maximum of t independent, identically distributed random variables have (Formula presented.) and Ft for their survival (minimum) and the distribution (maximum) functions, where (Formula presented.) and F are their common survival and distribution functions, respectively. We provide stochastic interpretation for these survival and distribution functions for the case when t > 0 i
In this study, numerical simulations are performed to investigate the effect of dimple location on the flow structure and heat transfer characteristics in a 90°-turned channel with pin fins. Results of the flow structure, heat transfer on the endwall, and friction factor are included in this study. It is found that the dimple location has an impact on the flow structure and heat transfer both for
Abstract: A search is presented for a new, light boson with a mass of about 1 GeV and decaying promptly to jets of collimated electrons and/or muons (lepton-jets). The analysis is performed with 20.3 fb−1 of data collected by the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a centre-of-mass energy of 8 TeV. Events are required to contain at least two lepton-jets. This
A new Modelica library is presented that is used to model safe hierarchical state machines in combination with any Modelica model, e.g., controllers, logical blocks, and physical systems described by differential-algebraic equations. It has been designed for simple usage, to guarantee safety properties and to harmonise with the design of the new Modelica_EmbeddedSystems library. Furthermore, new b
This paper suggests an approach to conceptualize problems of unsustainability situations by embedding the Drivers-Pressure-State-Impact-Response (DPSIR) scheme within a system of jurisdictional levels represented by Torsten Hägerstrand’s system of nested domains. Taken together these frameworks offer one way to decipher complex situations at different levels by identifying specific problem areas,
The end-to-end assignment of bandwidth to node-pairs (demands) in a communication network can be considered fair if it is distributed according to the max-min fair (MMF) principle. This paper investigates the problem of obtaining an MMF allocation if each demand is required to use exactly one path (i.e., to use unsplittable flows). First it is shown that the problem is NP-hard, both if each demand
We consider a probabilistic model for workload input into a telecommunication system. It captures the dynamics of packet generation in data traffic as well as accounting for long-range dependence and self-similarity exhibited by real traces. The workload has stationary increments as observed in high-speed data networks for certain periods. Such periods with peak demand can be studied with this mod
