Wavelet Method for Denoising Pressure Data for Transient Analysis
RN Ayitey Akoto, BK Mussey, AO Igbokoyi
Jun 09, 2026· Vol.Volume 5· 810 views

Unlike the Fourier theory that lacks scaling and translation parameters, the wavelet theory provides a new platform for the so-called de-oising workflow where noise in a signal or set of data is reduced. This work demonstrates how the wavelet transform can be used as a de-noising tool to denoise pressure transient data for PTA. The target is to create a smoother yet representative data pattern out of a noisy set of data. Two flow regimes were clearly identified from a noisy set of pressure transient data – spherical and radial flow regimes. The data points were then fitted to simple mathematical models describing spherical and radial flows. The p-values from the Chi-squared distributions were less than 0.05, indicating a perfect fit of the data points to the models.

Examining English Language Learning Anxiety and Student Achievement at Takoradi Technical University in Ghana

Literature shows that English language learning anxiety (ELLA) has a debilitating effect on English language achievement (ELA) and that knowledge of ELLA is essential for successful language acquisition. Yet, most of these studies focus on English as a foreign language, leaving studies on English as a second language on the fringes of current literature, though the two are distinct. Thus, this paper examined the link between ELLA and ELA among Takoradi Technical University students. It also determined the individual relationships of ELLA components with the students’ ELA. Using Horwitz et al.’s (1986) Foreign Language Classroom Anxiety Scale and students’ Examination scores, this paper tested students’ ELLA and ELA respectively with a sample of 351 students. A negative correlation was found between ELLA and ELA. Though the components of ELLA: Communication apprehension (CA), Test anxiety (TA) and Fear of negative evaluation (FNE), were negatively correlated with the students’ ELA, CA was most strongly correlated with ELA. Apparently, even in the context of English as a second language, the students were anxious when it comes to classroom communication. It is recommended that teachers support and encourage an interest in learning English and use classroom activities that are less likely to induce fear.
