Sentiment analysis:towards a tool for analysing real-time students feedback [PDF]

open access: yes, 2014
Students' real-time feedback has numerous advantages in education, however, analysing feedback while teaching is both stressful and time consuming. To address this problem, we propose to analyse feedback automatically using sentiment analysis.

Time-domain analysis of RF and microwave autonomous circuits by vector fitting-based approach [PDF]

open access: yes, 2019
This work presents a new method for the analysis of RF and microwave autonomous circuits directly in the time-domain, which is the most effective approach at simulation level to evaluate nonlinear phenomena. For RF and microwave autonomous circuits, time-

Time Domain Vibration Analysis of an Ice Shelf

open access: yesJournal of Marine Science and Engineering
A method is presented to calculate the vibrations of an ice shelf floating in shallow water under different boundary conditions. One condition is that there is no flux, which reduces all calculations and the other is that there is no pressure at the ...

Search for HRV-parameters that detect a sympathetic shift in heart failure patients on ß-blocker treatment

open access: yesFrontiers in Physiology, 2013
Background: A sympathetic shift in heart rate variability (HRV) from high, beat-to-beat, to lower frequencies may be an early signal of deterioration in a monitored patient. Most chronic heart failure (CHF) patients receive ß-blockers. This tends to

Thermoacoustic instability - a dynamical system and time domain analysis

open access: yes, 2014
This study focuses on the Rijke tube problem, which includes features relevant to the modeling of thermoacoustic coupling in reactive flows: a compact acoustic source, an empirical model for the heat source, and nonlinearities.

TIME Domain Analysis of Sound Signals for Bearing Damage Identification [PDF]

open access: yes, 2014
Time domain analysis requires less computational time compared to the frequency domain. Analysis is performed directly on the signal without any conversion at all.

Real‐World Pediatric Blinatumomab Administration: Access to Outpatient Care Delivery and Impact of a Hospital‐Dispensed Model

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Blinatumomab has been shown to be highly effective for patients with pediatric B‐ALL and has recently become standard of care therapy. Due to its past use in the clinical trial setting, there is limited information available about real‐world administration.

Fatigue life study of the door on the new-type 160 km/h railway box wagon

open access: yes机车电传动, 2023
During train operation, influenced by track irregularity or random wind load, the vehicle body is continuously under the impact of random vibration loads, which will cause fatigue damage to the vehicle structure in severe cases. To ensure train operation
