Identifying lethal vector and non-vector mosquitoes can become difficult for a layperson and sometimes even for experts, considering their visual similarities. Recently, deep learning (DL) became a solution to assist in differentiating the two mosquito types to reduce infections and enhance actions against them. However, the existing methods employed to develop a DL model for...

This paper presents a design of an exoskeleton robot to aid in lower-body rehabilitation of patients who have trouble with walking. The robot is intended for people who suffered from spinal cord injuries, brain trauma, cerebral palsy, Parkinson’s disease, and stroke. Specifically, a robot for rehabilitation can aid therapists and patients by letting the robot...

In this paper, we find a special type of non-traceable cubic bridge graph called well-formed graph whose central fragment is isomorphic to a hairy cycle and whose branches are pairwise isomorphic. We then show that a well-formed graph can be partition into isomorphic subgraph. Some properties of a well-formed graph such as perfect matching, matching number, decomposition...

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...
