Average-Case Quantum Query Complexity [PDF]

open access: yes, 2000
We compare classical and quantum query complexities of total Boolean functions. It is known that for worst-case complexity, the gap between quantum and classical can be at most polynomial.

MGC-VSLAM: A Meshing-Based and Geometric Constraint VSLAM for Dynamic Indoor Environments

open access: yesIEEE Access, 2020
Visual Simultaneous Localization and Mapping (VSLAM) system is considered to be a fundamental capability for autonomous mobile robots. However, most of the existing VSLAM algorithms adopt a strong scene rigidity assumption for analysis convenience, which

Instability of a Uniform Plankton Distribution [PDF]

open access: yesModeling, Identification and Control, 1981
For a plankton model system, a horizontally uniform distribution becomes unstable if the zooplankton component carries out diurnal vertical migrations in an ocean with a speed difference between the currents in upper and lower waterlaycrs. With turbulent

Complete Study of an Original Power-Exponential Transformation Approach for Generalizing Probability Distributions

open access: yesAxioms, 2023
In this paper, we propose a flexible and general family of distributions based on an original power-exponential transformation approach. We call it the modified generalized-G (MGG) family.

Uniform distribution and algorithmic randomness

open access: yes, 2012
A seminal theorem due to Weyl states that if (a_n) is any sequence of distinct integers, then, for almost every real number x, the sequence (a_n x) is uniformly distributed modulo one. In particular, for almost every x in the unit interval, the sequence (

The Maximum Uniform Message Distribution Problem

open access: yesIEEE Access, 2018
This paper introduces the maximum uniform message distribution (MUMD) problem, which can be present in delay-tolerant communication networks, where the destination of the messages is not present in the network.

Quantum wiretap channel with non-uniform random number and its exponent and equivocation rate of leaked information

open access: yes, 2013
A usual code for quantum wiretap channel requires an auxiliary random variable subject to the perfect uniform distribution. However, it is difficult to prepare such an auxiliary random variable.

Stability of second-order recurrences modulo pr

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
The concept of sequence stability generalizes the idea of uniform distribution. A sequence is p-stable if the set of residue frequencies of the sequence reduced modulo pr is eventually constant as a function of r.

Towards the field binary population: Influence of orbital decay on close binaries

open access: yes, 2012
Surveys of the binary populations in the solar neighbourhood have shown that the periods of G- and M-type stars are log-normally distributed. However, observations of young binary populations suggest a log-uniform distribution.

A Simulation and Experiment on the Optimization Design of an Air Outlet Structure for an Air-Assisted Sprayer

open access: yesAgriculture, 2023
In response to the issues of low-velocity zones and non-uniform jet velocity distribution in the airflow field of traditional air-assisted orchard sprayers, an arc-shaped air outlet suitable for axial-flow air-assisted systems is designed.
