A systematic literature review on long‐term localization and mapping for mobile robots

Journal of Field Robotics, Volume 40, Issue 5, Page 1245-1322, August 2023., 2023
Abstract Long‐term operation of robots creates new challenges to Simultaneous Localization and Mapping (SLAM) algorithms. Long‐term SLAM algorithms should adapt to recent changes while preserving older states, when dealing with appearance variations (lighting, daytime, weather, or seasonal) or environment reconfiguration. When also operating robots for

Unified Approach to Fractional Calculus Images Involving the Pathway Transform of Extended k‐Gamma Function and Applications

Advances in Mathematical Physics, Volume 2022, Issue 1, 2022., 2022
A path way model is concerned with the rules of swapping among different classes of functions. Such model is significant to fit a parametric class of distributions for new data. Based on a such model, the path way or Pδ transform is of binomial type and contains a family of different transforms.

Certain Properties of Generalized M‐Series under Generalized Fractional Integral Operators

Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021
The aim of this study is to introduce new (presumed) generalized fractional integral operators involving I‐function as a kernel. In addition, two theorems have been developed under these operators that provide an image formula for this generalized M‐series and also to study the different properties of the generalized M‐series.

Relation of Some Known Functions in terms of Generalized Meijer G‐Functions

Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021
The aim of this paper is to prove some identities in the form of generalized Meijer G‐function. We prove the relation of some known functions such as exponential functions, sine and cosine functions, product of exponential and trigonometric functions, product of exponential and hyperbolic functions, binomial expansion, logarithmic function, and sine ...

Fractional q‐Integral Operators for the Product of a q‐Polynomial and q‐Analogue of the I‐Functions and Their Applications

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
In this article, we derive four theorems concerning the fractional integral image for the product of the q‐analogue of general class of polynomials with the q‐analogue of the I‐functions. To illustrate our main results, we use q‐fractional integrals of Erdélyi–Kober type and generalized Weyl type fractional operators. The study concludes with a variety

Small Flux Superpotentials for Type IIB Flux Vacua Close to a Conifold

Fortschritte der Physik, Volume 68, Issue 11-12, December 2020., 2020
Abstract We generalize the recently proposed mechanism by Demirtas, Kim, McAllister and Moritz[1] for the explicit construction of type IIB flux vacua with to the region close to the conifold locus in the complex structure moduli space. For that purpose tools are developed to determine the periods and the resulting prepotential close to such a ...

Unraveling spatiotemporal variability of arbuscular mycorrhizal fungi in a temperate grassland plot

Environmental Microbiology, Volume 22, Issue 3, Page 873-888, March 2020., 2020
Summary Soils provide a heterogeneous environment varying in space and time; consequently, the biodiversity of soil microorganisms also differs spatially and temporally. For soil microbes tightly associated with plant roots, such as arbuscular mycorrhizal fungi (AMF), the diversity of plant partners and seasonal variability in trophic exchanges between

On Transformation Involving Basic Analogue of Multivariable H‐Function

Journal of Function Spaces, Volume 2020, Issue 1, 2020., 2020
In this article, fractional order q‐integrals and q‐derivatives involving a basic analogue of multivariable H‐function have been obtained. We give an application concerning the basic analogue of multivariable H‐function and q‐extension of the Leibniz rule for the fractional q‐derivative for a product of two basic functions.

HQET quark-gluon vertex at one loop [PDF]

, 2001
We calculate the HQET quark-gluon vertex at one loop, for arbitrary external momenta, in an arbitrary covariant gauge and space-time dimension. Relevant results and algorithms for the three-point HQET integrals are presented.
