A Novel Subspace Decomposition with Rotational Invariance Technique to Estimate Low-Frequency Oscillatory Modes of the Power Grid.

Publication Type: Academic Journal

Source(s): Journal of Electrical & Computer Engineering. 5/29/2023, p1-11. 11p.

Abstract: This paper proposes modified Karhunen–Loeve transform with total least square estimation of signal parameters using rotational in-variance technique (MKLT-TLS-ESPRIT) to approximate the low-frequency oscillatory modes. MKLT decreases the impact of high...

Investigation of the Process of Evolution of Traces of Explosives Carried by Fingerprints Using Polarimetric Macrophotography and Remote LF/LIF Method.

Publication Type: Academic Journal

Source(s): Photonics. Jul2023, Vol. 10 Issue 7, p740. 8p.

Abstract: The results of a study of the degradation of the cyclotrimethylenetrinitramine (RDX) traces carried in fingerprints depending on the fingerprint number are presented. The surface concentration of the trace was assessed using macrophotography in polariz...

An Approach to Canonical Correlation Analysis Based on Rényi's Pseudodistances.

Publication Type: Academic Journal

Source(s): Entropy. May2023, Vol. 25 Issue 5, p713. 21p.

Abstract: Canonical Correlation Analysis (CCA) infers a pairwise linear relationship between two groups of random variables, X and Y. In this paper, we present a new procedure based on Rényi's pseudodistances (RP) aiming to detect linear and non-linear relations...

Optomechanics-Based Quantum Estimation Theory for Collapse Models.

Publication Type: Academic Journal

Source(s): Entropy. Mar2023, Vol. 25 Issue 3, p500. 10p.

Abstract: We make use of the powerful formalism of quantum parameter estimation to assess the characteristic rates of a continuous spontaneous localization (CSL) model affecting the motion of a massive mechanical system. We show that a study performed in non-equ...

Estimation of compositeness with correction terms.

Publication Type: Conference

Source(s): EPJ Web of Conferences. 11/18/2022, Vol. 271, p1-4. 4p.

Abstract: The compositeness X is defined as the probability to observe the composite structure such as the hadronic molecule component in a bound state. One of the model-independent approaches to calculate X is the weak-binding relation. However, when the scatte...

Machine Learning Techniques for Estimating Soil Moisture from Smartphone Captured Images.

Publication Type: Academic Journal

Source(s): Agriculture; Basel. Mar2023, Vol. 13 Issue 3, p574. 25p.

Abstract: Precise Soil Moisture (SM) assessment is essential in agriculture. By understanding the level of SM, we can improve yield irrigation scheduling which significantly impacts food production and other needs of the global population. The advancements in sm...

Water Quality Assessment of Wenyu River with Variable Weight Cloud Model.

Publication Type: Academic Journal

Source(s): Nature Environment & Pollution Technology. Mar2023, Vol. 22 Issue 1, p63-72. 10p.

Abstract: The water resource is an important guarantee of social and economic sustainable development. The improvement of water's ecological carbon sequestration ability is a direct response to the goal of "double carbon". Water quality directly affects its carb...

Influence of the Curing Process on the Fatigue Strength and Residual Strength of a Fiber Composite Estimation Using the Theory of Markov Chains.

Publication Type: Academic Journal

Source(s): Advances in Science & Technology Research Journal. 2023, Vol. 17 Issue 2, p53-62. 10p.

Abstract: The paper deals with the influence of quality failure of matrix post-curing on the strength of such complex and difficult “new generation” materials as fiber composites, especially those with polymer matrix. The performed statistical analysis of the co...

Several Tree-Based Solutions for Predicting Flyrock Distance Due to Mine Blasting.

Publication Type: Academic Journal

Source(s): Applied Sciences (2076-3417). Feb2023, Vol. 13 Issue 3, p1345. 23p.

Abstract: Blasting operations involve some undesirable environmental issues that may cause damage to equipment and surrounding areas. One of them, and probably the most important one, is flyrock induced by blasting, where its accurate estimation before the opera...

Robust Statistics for Portfolio Construction and Analysis.

Publication Type: Academic Journal

Source(s): Journal of Portfolio Management. 2023 Quantitative Tools, Vol. 49 Issue 9, p105-139. 35p.

Abstract: Asset returns and factor exposures frequently exhibit small fractions of extreme outliers, which are often associated with fat-tailed distributions and can have very adverse influence on classical least-squares regression estimators and sample covarian...
