The primary objective of this study is to segment the uterine fibroids (leiomyoma) from the ultrasound images of the uterus through semantic segmentation, followed by second-order statistical feature extraction using the Gray-level Co-occurrence Matrix (GLCM). The next objective of the study is to compare the performance of the state-of-the-art method namely Vision Transformer (ViT) with...

This research study proposes an Intelligent Parking Lot Management System (IPLMS) utilizing real-time license plate recognition technology to address parking management challenges arising from rapid urbanization and increased vehicle ownership. The system enhances the four-stage license plate recognition process (preprocessing, positioning, character segmentation, and character recognition) with variable precision recognition, recognition result voting, and idle/active...

A negative voltage generator was developed that can be used in the drivers of smart window films (SWF), which have typical operating voltages of ±8 to ±10 V. It consists of four Negative Charge Pump (NCP) stages and a 4-phase non-overlapping Clock Generator (CG), where the 4 NCP stages are configurable by external digital signals....

This paper presents a highly-efficient dual-mode HV (high voltage) buck converter which operates at both light and heavy load currents. For the conversion efficiency to be improved at two different load conditions, the dual-mode design composed of pulse width modulation (PWM) and pulse frequency modulation (PFM) was implemented using TSMC 0.5-µm HV CMOS process. The...

This research illustrates a DC–DC buck converter with a pulse width modulation (PWM) feedback control loop and capable of power supply voltage range from VDD to 2.5× VDD, which is equivalent to 5–14 V. It is a single chip with area of 1.379 × 0.813 mm² using 0.5 µm HV CMOS process, where high voltage...

This paper presents a Schmitt-trigger-based SRAM with a separated read port, which significantly improves read static noise margin (RSNM) and consumes low energy. Post-layout simulation results show that the proposed design performed better than the conventional 6T SRAM cell. The SNM of the designed cell is 1.16 mV higher than the conventional 6T SRAM cell...

Combining the Finite Element Method (FEM) and Boundary Element Method (BEM) opened a wide array of solutions for ordinary and partial differential equations deemed helpful for engineers and scientists. These methods were applied in various branches of sciences and engineering, especially in computational electromagnetics. This study used computational software to illustrate the coupled FEM-BEM solution...

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...
