Analyzing the Performance of Ideological and Political Education in Universities: A Neutrosophic Approach to Handling Truth, Indeterminacy, and Falsehood in Students' Responses [PDF]

open access: yesNeutrosophic Sets and Systems
This paper presents a new way to evaluate ideological and political education (IPE) in universities using neutrosophic logic. Unlike traditional surveys that only show if students agree or disagree, this method looks deeper by also measuring how unsure ...

Noise Infusion as a Confidentiality Protection Measure for Graph-Based Statistics [PDF]

open access: yes, 2015
We use the bipartite graph representation of longitudinally linked employer-employee data, and the associated projections onto the employer and employee nodes, respectively, to characterize the set of potential statistical summaries that the trusted ...

Refined Upper Bounds on Stopping Redundancy of Binary Linear Codes [PDF]

open access: yes, 2015
The $l$-th stopping redundancy $\rho_l(\mathcal C)$ of the binary $[n, k, d]$ code $\mathcal C$, $1 \le l \le d$, is defined as the minimum number of rows in the parity-check matrix of $\mathcal C$, such that the smallest stopping set is of size at least

A Discriminative Model for Early Detection of Anthracnose in Strawberry Plants Based on Hyperspectral Imaging Technology

open access: yesRemote Sensing, 2023
Strawberry anthracnose, caused by Colletotrichum spp., is a major disease that causes tremendous damage to cultivated strawberry plants (Fragaria × ananassa Duch.).

Spectrophotometric calibration of low-resolution spectra

open access: yes, 2020
Low-resolution spectroscopy is a frequently used technique. Aperture prism spectroscopy in particular is an important tool for large-scale survey observations. The ongoing ESA space mission Gaia is the currently most relevant example.

On Fuglede’s conjecture and the existence of universal spectra [PDF]

open access: yes, 2006
Recent methods developed by, Too [18], Kolountzakis and Matolcsi [7] have led to counterexamples to Fugelde's Spectral Set Conjecture in both directions.

Recovery of eigenvectors from eigenvalues in systems of coupled harmonic oscillators

open access: yesPhysical Review Research, 2020
The eigenvector-eigenvalue identity relates the eigenvectors of a Hermitian matrix to its eigenvalues and the eigenvalues of its principal submatrices in which the jth row and column have been removed.

AN APPLICATION OF ROLL-INVARIANT POLARIMETRIC FEATURES FOR CROP CLASSIFICATION FROM MULTI-TEMPORAL RADARSAT-2 SAR DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Crops are dynamically changing and time-critical in the growing season and therefore multitemporal earth observation data are needed for spatio-temporal monitoring of the crops.

Partially shared buffers with full or mixed priority [PDF]

open access: yes, 2011
This paper studies a finite-sized discrete-time two-class priority queue. Packets of both classes arrive according to a two-class discrete batch Markovian arrival process (2-DBMAP), taking into account the correlated nature of arrivals in heterogeneous ...
