The advent of the fourth industrial revolution (4IR) offers promising improvements in operational efficiency and profitability for various industries, and can be a key component to leapfrog the many sectors of manufacturing in the Philippines. This will necessitate the reskilling and upskilling of Filipino automation engineers and instrumentation technicians to commission and maintain smart technologies...

Industrialization has a major impact on the ecosystem and the natural water composition particularly in places close to cities andmanufacturing areas. Copper (Cu2+) ion is one of the heavy metals present in the industrial effluent and is considered to be a toxicheavy-metal contaminant accounting to its extreme persistence and bioaccumulation. Current techniques for determining Cu2+ions...

This study used carbon rods from spent zinc-carbon batteries as a source of exfoliated graphite (EG) to produce conductive filament composites for fused deposition modeling 3D printing. The EG filler was prepared through microwave irradiation, while the resulting 3D printable electroconductive EG composites were prepared using polylactic acid (PLA) and polyethylene glycol (PEG) as the...

Diabetic retinopathy is a serious complication needing prompt diagnosis and medication to avert vision loss. Lesions caused by the condition are difficult to track because they are hidden behind the eye’s structure in small and subtle forms. To extract relevant features., we created a robust pipeline using multiple preprocessing techniques., image segmentation architecture (DR-UNet) with...

Coffee plays a cultural part in the lives of people. Eight out of ten adults in the Philippines drink an average of 2.5 cups of coffee per day, and nine out of ten households have coffee in their pantries. In 2021, it is reported that coffee will be an approximately PHP 3.0 billion (USD 5...

For high-resolution, high-accuracy applications, re-cent DPWM (digital PWM) researches use long DFF arrays, resulting in clock skew that may compromise DPWM performance. This study proposed a DPWM based on a matrix phase shifter and clock gating technique which only selects a specific row of DFFs during operation depending on the required level of Vo. The proposed...

Interactive Whiteboard (IWB) Systems are increasingly being used to replace traditional whiteboards in educational activities, making them more efficient and interesting for both teachers and students. However, no studies have been conducted to investigate how age, educational level, and employment status can impact the adoption and usage of IWB systems in the educational setting. The...

Jackfruit is a fruit native to South and Southeast Asia that is now cultivated all over the world due to its adaptability, as it can be eaten both ripe and unripe. This study was conducted to accurately identify the Jackfruit’s ripeness. Four MQ families have been identified as the most effective for classifying the ripeness...

Filipino Sign Language (FSL) is a distinctive form of sign language with its own set of pose, gestures, and grammar, which can cause a challenge in terms of identifying it. Earlier researches have identified three categories of sign language recognition methods, these are the gloves-based, vision-based and hybrid. Existing studies are only limited to recognizing...

The Low-Cost Microplastic Filtration System is a device designed to aid in the resolution of the growing problem with microplastics. With an estimated 48 million shopping bags and 164 million sachets used daily (Philippine research uncovers microplastics inside a regularly eaten fish, 2020), the Philippines is one of the most prolific users of single-use plastics....
