Evaluating Compressed Sensing Matrix Techniques: A Comparative Study of PCA and Conventional Methods
Advance Sustainable Science, Engineering and Technology (ASSET)
Vol 7
, No 2
(2025)
This research examines the performance of various compressed sensing matrix techniques, with a focus on Principal Component Analysis (PCA) compared to conventional methods. By applying these techniques to a range of high-dimensional datasets, we assess their effectiveness in reducing data dimensionality while preserving essential information. Our results demonstrate that PCA consistently outperforms traditional methods in terms of both accuracy and computational efficiency. These findings have s...

This study addresses taxonomic uncertainty surrounding color variants of Procambarus clarkii in aquaculture and conservation contexts. We investigated whether commercially significant color morphs represent distinct subspecies or phenotypic variations of a single species. Using the cytochrome c oxidase subunit I (COI) gene as a molecular marker, we analyzed four color morphs (blue, white, orange, and brown) from aquaculture facilities in Banyumas Regency. DNA extraction, PCR amplification, and s...

Development of Electromagnetic-Based Physical Pendulum Practical Tools Using Infrared Sensors
Jurnal Penelitian Pembelajaran Fisika
Vol 16
, No 2
(2025)
Abstract. Basic physics practicums often face measurement accuracy constraints due to limited tools and human error. This study aims to develop an electromagnetic-based physical pendulum practicum tool using an infrared sensor and measure its feasibility in basic physics practicum lectures 1. The method used is Research and Development (R&D) with a descriptive quantitative approach and a 3D development model. The data analysis technique uses a Likert scale with a range of 1-5 which is conver...

Spectral and Molecular Modifications of Hydrophilic Silica Aerogel: A Study on Doping Effects and Structural Evolution
Advance Sustainable Science, Engineering and Technology (ASSET)
Vol 7
, No 2
(2025)
Silica gel has recently become an interesting material because of its importance in many applications in several fields such as medicine and sustainable technology. It has been found that the impregnation of some materials improves the synthetic properties of silica. Silica gel was prepared via mixed TEOS: ethanol: hydrochloric acid with molar ratios of 2:10:1.5. After doping with Diethyl in different concentrations 10-4, 10-5, and 10-6) g/cm3, the molecular properties were studied by examining...

This paper compares two single balanced mixer designs for ultra-wideband (UWB) of RF front-end at frequencies ranging from 3 to 10 GHz. The proposed mixer designs use two balun topologies for varying mixer performances. Thus, Design 1 incorporates a Coupled Line Balun and Design 2 incorporates a Branch Line Balun. Both designs make use of Skyworks' SMS7621 Schottky diodes, which have a low junction capacitance, and the Rogers RO4350B substrate, which has a dielectric constant of 3.48. The Coupl...
