Abstract:
Random numbers (RNs) have applications in many areas: lottery games, gambling, computer simulation, and, most importantly, cryptography [N. Gisin et al., Rev. Mod. Phys. 74 (2002) 145]. In cryptography theory, the theoretical security of the system calls for high quality RNs. Therefore, developing methods for producing unpredictable RNs with adequate speed is an attractive topic. Early on, despite the lack of theoretical support, pseudo RNs generated by algorithmic methods performed well and satisfied reasonable statistical requirements. However, as implemented, those pseudorandom sequences we

The basic reproduction number R0 is a concept which originated in population dynamics, mathematical epidemiology, and ecology and is closely related to the mean number of children in branching processes (reflecting the fact that the phenomena of interest are well approximated via branching processes, at their inception). Despite the very extensive literature around R0 for deterministic epidemic models, we believe there are still aspects which are not fully understood. Foremost is the fact that R0 is not a function of the original ODE model, unless we also include in it a certain (F,V) gradient

We distinguish two cases: LoD2 models are available and they are not. We apply Multi-Photo Geometrically Constrained Least Squares Matching for different kind of point measurements.

Abstract:
In this work, we study two simple yet general complexity classes, based on logspace Turing machines, that provide a unifying framework for efficient query evaluation in areas such as information extraction and graph databases, among others. We investigate the complexity of three fundamental algorithmic problems for these classes: enumeration, counting, and uniform generation of solutions, and show that they have several desirable properties in this respect. Both complexity classes are defined in terms of non-deterministic logspace transducers (NL-transducers). For the first class, we consider

Recently, increased computational power and data availability, as well as algorithmic advances, have led machine learning (ML) techniques to impressive results in regression, classification, data generation and reinforcement learning tasks.

To deal with difficulties arising from partitioning the fuzzy graph and its connectivity where forbidden induced subgraphs are a raised consideration, this work introduces the concept of k-secluded vertex sets in graph theory. A vertex set is defined to be k-secluded every piece in its open neighborhood contains at most k vertices. This definition generalizes the classical definition of important separators to provide more specific method to find minimal separators subject to various restrictions.

Developments in UAV sensors and platforms in recent decades have stimulated an upsurge in its application for 3D mapping.

However, in the context of 3D city mapping, further 3D modeling is required to generate 3D city models which is often performed manually using, e.g., photogrammetric stereoplotting.

Abstract:
Quadrilles were a popular genre of group dancing in the nineteenth century. Existing melodies were normally used to accompany the dancing sessions, but the monotony of their repetition and the cost of a professional piano player capable of improvising were an issue. Thus, the idea of a “machine” that would be able to endlessly produce quadrille music at no cost was suggesting itself. The Quadrille Melodist, a paper-based system for the generation of piano pieces, was published in nineteenth-century Victorian London by John Clinton, a “professor in the Royal Academy of Music.” Already in 1650,

Point clouds are a crucial data type for mmWave radar and are widely used in sensing applications such as human tracking and activity recognition. However, for indoor human sensing, the point clouds obtained by mmWave radar are often sparse. Previous studies attribute the sparsity to the limited sensing capabilities of mmWave radar, underestimating the impact of CFAR---a key algorithmic component of mmWave systems---on point cloud quality. Through empirical studies, we find that the spatial-based CFAR widely used in existing works suffers from a severe energy masking issue. This is because the
