The machine learning approach is widely used to investigate human activities, such as in the art field. In the music industry, a song's popularity is essential to predict before it is released. In this paper, we were interested in predicting the popularity of songs using the __-nearest neighbor regression. The Spotify app was used to gather some information related to the audio features of a song, i.e., song duration, instrumentalness, loudness, acousticness, danceability, energy, liveness, speechiness, audio valence, key, audio mode, tempo, and time signature. This research used mixed-type variables; thus, the dissimilarity is measured using the Gower distance. In addition, two weighting methods were also compared to predict song popularity. Using 10-fold cross-validation, we found that the inversely proportional weights-distance showed better prediction performance when compared with equal weight. Moreover, we also found the best performance in predicting the song popularity is obtai.....

This study aims to characterise 4-Sulfocalix[4]arene (SC[4]) thin films using Atomic Force Microscopy (AFM) in analysing its thickness and surface morphology. Quartz substrates were cleaned using ultrasonic cleaning with an Elmasonic P70H. SC[4] thin films were then fabricated on a quartz surface using WS-400BZ-6NPP/A1/AR1 model spin coater from Laurel Technologies, producing thin films with 5, 10, 15, and 20 layers. Each thin film was characterised in the tapping mode of the AFM Park System NX-10. Scans were conducted on different film areas of different scales, and the data were analysed using XEI Data Processing and Analysis Software. Height measurements obtained via Line Profile analysis revealed a progressive increase in film thickness with the additional layers, demonstrating a significant linear relationship. AFM images showed precise 2D and 3D surface topography, indicating that the thin films became uneven and non-uniform with the addition of more layers. The findings demonstr.....

X-Ray shielding efficiency of sand reenforced plastic concrete blocks synthesized using sand and waste sachet water plastic in the percentage ratio of 50:50, 30:70, 10:90 and 0:100 has been studied in this paper. The density of the synthesized concrete blocks and their x-ray shielding characteristics were measured using a densitometer and a set of x-rays shielding fixed diagnostic x-ray machine and digital Geiger counter respectively. The density value decreased as the sand percentage decreased from 1.922 gcm-1 to 1.250 gcm-1 with an increasing plastic percentage, resulting from the substitution of sand with lighter plastic. The linear attenuation coefficient (LAC) and the mass attenuation coefficient (MAC) values increased with an increase in the percentage of plastic while the tenth value layer (TVL) and half value layer (HVL) decreased with increase in the percentage of plastic in the concrete material. The value of the mean free path (MFP) appeared higher when more sand composition.....

ChatGPT has taken the world by storm in recent years with its ability to interact and respond in a _human way_ form. Despite the warm reception, there are also concerns regarding integrity, plagiarism and worry about too much reliance on ChatGPT. Nevertheless, just like with other technologies, resistance is futile, yet its benefit must be embraced while maintaining some guidelines to be adhered. This paper presents the implementation of ChatGPT in teaching and learning theoretical parts of Introduction to Networking course. Though this is a laboratory-embedded course, the cognitive skills part still contributes to 40% of the assessment. It is challenging to maintain engagement and attract the attention of students during lecture sessions compared to laboratory sessions. Therefore, ChatGPT is utilized in various techniques to achieve the mentioned objective. Keywords: ChatGPT, Education, Teaching, Learning, Networking..

Tuberculosis (TB) transmission frequently occurs in a household or group within a population, resulting in a variety of spatial patterns. However, the apparent spatial clustering of TB may represent the ongoing transmission or colocation of associated risk factors, which can vary significantly based on the type of data available, the analysis methods used, and the dynamics of the underlying population. This study aims to review the spatial analyses used for monitoring the trends involving and associations between risk factors and TB cases by applying the concept of spatial epidemiology. The role of the Geographic Information System in spatial epidemiology is discussed. Previous studies involving spatial analysis of TB cases - which include kriging, spatial autocorrelation, kernel density estimation, hotspot analysis, and regression analysis - are reviewed. The type of analysis was chosen based on the purpose of each study, which could explain the role of the transmission to reactivatio.....
