Forecasting Blood Demand Using the Support Vektor Regression Method (Case Study: Blood Transfusion Unit-PMI Central Lombok)

open access: yesJISA (Jurnal Informatika dan Sains), 2023
Blood is an important component produced by the human body. Blood is also a very vital part of human survival. When blood levels in the human body are less than they should be, the way to overcome this is by donating blood or blood transfusion.

Sampling and Reconstruction of Graph Signals via Weak Submodularity and Semidefinite Relaxation

open access: yes, 2017
We study the problem of sampling a bandlimited graph signal in the presence of noise, where the objective is to select a node subset of prescribed cardinality that minimizes the signal reconstruction mean squared error (MSE).

Spin Liquid in the Multiple-Spin Exchange model on the Triangular lattice: 3He on graphite

open access: yes, 1998
Using exact diagonalizations, we investigate the T=0 phase diagram of the Multi-Spin Exchange (MSE) model on the triangular lattice: we find a transition separating a ferromagnetic phase from a non-magnetic gapped Spin Liquid phase.

How much does volatility influence stock market returns? Empirical evidence from India

open access: yesIIMB Management Review, 2023
The purpose of this paper is to establish and estimate the extent of the volatility anomaly (VA). We examine the impact of the beta, variance, relative-beta, and relative-variance measures on the stock returns for NIFTY500 companies, for the 10-year ...

Adaptive computation of multiscale entropy and its application in EEG signals for monitoring depth of anesthesia during surgery [PDF]

open access: yes, 2012
Entropy as an estimate of complexity of the electroencephalogram is an effective parameter for monitoring the depth of anesthesia (DOA) during surgery.

Almon-KL estimator for the distributed lag model

open access: yesArab Journal of Basic and Applied Sciences, 2021
The Almon technique is widely used to estimate the parameters of the distributed lag model (DLM). The technique suffers a setback from the challenge of multicollinearity because the explanatory variables and their lagged values are often correlated.

Scalable Hash-Based Estimation of Divergence Measures

open access: yes, 2018
We propose a scalable divergence estimation method based on hashing. Consider two continuous random variables $X$ and $Y$ whose densities have bounded support.

In vitro properties of patient serum predict clinical outcome after high dose rate brachytherapy of hepatocellular carcinoma

open access: yesMolecular Oncology, EarlyView.
Following high dose rate brachytherapy (HDR‐BT) for hepatocellular carcinoma (HCC), patients were classified as responders and nonresponders. Post‐therapy serum induced increased BrdU incorporation and Cyclin E expression of Huh7 and HepG2 cells in nonresponders, but decreased levels in responders.

Investigation on the Effects of Structural Dynamics on Rolling Bearing Fault Diagnosis by Means of Multibody Simulation

open access: yesInternational Journal of Rotating Machinery, 2018
The present study aims to combine the fields modal analysis and signal processing and to show the use of Frequency Response Function (FRF), as a vibration transfer path, in enhancing reliability and abilities of the next generation vibration-based ...

RIDGE LEAST ABSOLUTE DEVIATION PERFORMANCE IN ADDRESSING MULTICOLLINEARITY AND DIFFERENT LEVELS OF OUTLIER SIMULTANEOUSLY

open access: yesBarekeng, 2022
If there is multicollinearity and outliers in the data, the inference about parameter estimation in the LS method will deviate due to the inefficiency of this method in estimating.
