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...

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...

Improper sitting posture is a common issue affecting many individuals, even young ones. Prolonged periods of sitting, whether at work, studying, or at home, can lead to back pain and other health problems. The study focused on the software’s material specifications and system flow required to create the system. The engineering design process involved using...

The current 5G network needs to achieve a considerably larger link capacity and ultra-low latency to enhance mobile broadbands and support emerging mobile applications and massive IoT. Thus, implementing MIMO-OFDM Spatial Multiplexing and Hybrid Beamforming techniques helped increase the information capacity using multiple transmit and receive antennas. At the same time, these can improve the...

Providing universities with high technology-enabled automation tools to support the administrative decision-making processes will enable them to achieve their objectives. For an institution to succeed in its everyday tasks, it should come up with the emerging and modernized management services constituted, among others, by cloud, mobile, and business analytics technology. With this, the institution’s operations...

In this paper an FPGA-based radio transceiver that operates on a frequency band from unused TV white space – specifically 512 MHz – 518 MHz – is presented. The investigation was done to introduce an application of TV white space and FPGA hardware in creating a communication system for disaster rescue operations and in hopes...
