The world is currently undergoing the fourth Industrial Revolution (4IR), in which information plays a crucial role in everyday life. However, those with visual impairments are unable to access information by visual means. Approximately 237 million individuals worldwide suffer from vision impairment. The Refreshable Braille Display (RBD) is considered the most advanced and significant instructional tool for the visually impaired (VI), garnering interest from scientists and researchers worldwide. There are numerous technologies available to actuate the RBD. A comprehensive and meticulous examination of the existing technologies is necessary to make the proper choice of actuating technology in relevant applications. This paper aims to categorize the published articles based on the different types of actuation technologies that exist, and to examine each technology in terms of its benefits, drawbacks, and technical and economic parameters such as cost, power consumption, frequency, durability, etc. The analysis demonstrated that the electromagnetic actuation method is the most suitable approach from both an economic and technical standpoint. The authors proposed a RBD that utilizes the electromagnetic actuation approach. This method involves the use of a permanent magnet, electromagnet, and a cam in each braille pin. The proposed method is anticipated to fulfill all the necessary criteria and specifications of a braille display. The authors have already finished creating the computer-aided design (CAD) model of the proposed approach.

One of the most critical challenges in today’s rapidly expanding electrical world is maintaining power quality, efficiently distributing electricity without significant losses is difficult, and it's crucial to ensure that the quality of power remains within acceptable limits. The versatile dual control methodology of the Unified Power Quality Conditioner (UPQC) offers an effective solution to manage power distribution and address power quality issues. UPQC compensates for both current and voltage irregularities in reactive loads while also eliminating harmonics in the load current under distorted supply conditions. This project explores various techniques to enhance power efficiency, starting with the use of a UPQC integrated with a PID controller to address power efficiency challenges. To further improve power quality, an advanced solution using a UPQC with an ANFIS controller has been implemented, significantly enhancing performance.

The prevalence of breast cancer has led to increased interest in its classification among healthcare scholars. Deep learning techniques and self-attention-based transformers have gained popularity in breast image analysis. However, self-attention’s quadratic complexity limits its capacity and interpretability, disregarding sample-to-sample association. To address this issue, a study introduces a novel attention mechanism called External Attention Multi-Layer Perceptron (EAMLP). EAMLP utilizes two external, tiny, learnable, shared retention units implemented with linear and normalization layers. By leveraging the linear complexity of external attention, this approach reduces operational complexity while considering all data point connections. The study evaluates the proposed model’s effectiveness using two publicly available datasets: Breast Histopathology Images and the BreakHis dataset. The model’s performance is assessed using different image sizes and numbers of dense layers. Additionally, a self-attention-based transformer is experimentally tested for comparison. The results demonstrate that the proposed model achieves a maximum accuracy of 95.73%.
