Enhanced Gas-Sensing Performance of Fe-Doped Ordered Mesoporous NiO with Long-Range Periodicity

Journal of Physical Chemistry C, 2015
This paper reports the effect of mesoporous morphology and metal doping on the gas-sensing behavior of ordered mesoporous nickel oxide (NiO) materials.

Traffic transformer: Capturing the continuity and periodicity of time series for traffic forecasting

Trans. GIS, 2020
Traffic forecasting is a challenging problem due to the complexity of jointly modeling spatio‐temporal dependencies at different scales. Recently, several hybrid deep learning models have been developed to capture such dependencies.

Point-to-Periodic and Periodic-to-Periodic Connections [PDF]

open access: possibleBIT Numerical Mathematics, 2004
The authors consider computing and continuing connecting orbits in parameter dependent dynamical systems. Some details of algorithms for computing connections between equilibria and periodic orbits, and between periodic orbits are given. The theoretical foundation of these techniques is given in the seminal work of \textit{W.-J. Beyn} [Contemp.

The work function of the elements and its periodicity

, 1977
A new compilation, based on a literature search for the period 1969–1976, is made of experimental data on the work function. For these 44 elements, preferred values are selected on the basis of valid experimental conditions.

Automatic and Generic Periodicity Adaptation for KPI Anomaly Detection

IEEE Transactions on Network and Service Management, 2019
Key performance indicator (KPI) anomaly detection (AD) is critical to ensure service quality and reliability. Due to the effects of work days, off days, festivals, and business activities on user behavior, KPIs may exhibit different patterns within ...

The role of periodicity in perceiving speech in quiet and in background noise.

Journal of the Acoustical Society of America, 2015
The ability of normal-hearing listeners to perceive sentences in quiet and in background noise was investigated in a variety of conditions mixing the presence and absence of periodicity (i.e., voicing) in both target and masker.

Carbon structures with three-dimensional periodicity at optical wavelengths

Science, 1998
Porous carbons that are three-dimensionally periodic on the scale of optical wavelengths were made by a synthesis route resembling the geological formation of natural opal.

Periodicity, Directionality, and Randomness: Wold Features for Image Modeling and Retrieval

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1996
One of the fundamental challenges in pattern recognition is choosing a set of features appropriate to a class of problems. In applications such as database retrieval, it is important that image features used in pattern comparison provide good measures of

On Periodic Solutions of the Periodic

Results in Mathematics, 1988
By treating the periodic Riccati equation $${\rm\dot{z}=a(t)z^2+b(t)z+c(t)}$$ as a dynamical system on the sphere S, the number and stability of its periodic solutions are determined. Using properties of Moebius transformations, an exact algebraic relation is obtained between any periodic solution and any complex-valued periodic solution.

Among the Periodicals

Childhood Education, 1991
Abstract In keeping with the theme of this issue, the reviews in this column are related to children and violence. The articles examine the effects that unsafe conditions have on children's lives and social and cognitive development, and on their behavior.
