    Wind speed influenced weather predictions, aerospace operations, and maritime operations, construction projects. This research aims to examine the relationship between Pulau Langkawi wind speed data during the southwest monsoons in 2019 and 2020. To model wind speed data that follows a normal distribution. An error-in-variables model (EIVM) is utilised, which is a linear functional relationship model (LFRM). The QQ-plots will be utilised to investigate the adequacy of the model’s fit. The maximum likelihood estimation (MLE) approach is employed to estimate the parameters of the model, while the covariance is calculated using the Fisher Information matrix. As a result, it is found that the estimated values demonstrate consistency and reduced dispersion. Thus, the findings could lead to a better knowledge of wind energy prediction

    Open Access (OA) is the new publishing model that allows unrestricted access and reuse of research outputs. OA accelerates discovery in the sense that researchers can freely read and build on new findings based on other research. While public seems to welcome more involvement in OA among academics, many researchers are still discussing about the challenges that they face to publish with OA journals including the issue of article processing charge (APC) and the quality of OA journals. This paper examines several aspects relate to OA publication such as publication productivity, citation impact, subject coverage, and publishing cost of Universiti Sains Malaysia (USM) based on SCOPUS data from 2013 to 2015. The findings show that School of Medical Sciences, Physics and Pharmacy dominated the OA publications. Thus, it also indicates that science-based researchers are highly inclined towards publishing in OA as compared to non-science researchers. Top three OA journals in the list are Plos One (Multidisciplinary), Acta Chrystallographica Section E (Chemistry) and Electronic Journal of Geotechnical Engineering (Engineering, Geology). Most of the authors tend to publish in Quartile 3 journals (43%), followed by Q2 (28%), Q1 (16%) and Q4 (13%). However, with regard to citation impact per paper (average), every paper in Q1 journal received 6.25 citations, followed by Q2 (2.8 citations), Q3 (1.33 citations) and Q4 (0.87 citation). The APC range of OA publication found to be from RM0 to RM15, 000 per paper. The study provides useful insights about OA publication among USM researchers which can guide other researchers who wish to engage with OA in the future. Further study can be done by interviewing authors, to further explore on the OA research funding, strategy in choosing OA journals to publish in and also the motivation in publishing with OA
