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...

The acceptability of food is significantly increased by the addition of herbs, spices, and medicinal plants. These biomaterials improve the shelf-life of food, delay its oxidation, and impart health-promoting properties as natural therapies. The physical and chemical properties of aromatic and medicinal plants are determined by their moisture content since water is the most significant...

Understanding how employees act at work to save energy and the meaning for sustainability and environmental protection is essential. This research aimed to analyze the influences of Subjective Norms (SN), Descriptive Norms (DN), and Environmental Knowledge (EK) on employees’ intention to save energy (ISE) in the Philippines (PH) and the Dominican Republic (DR). The effects...

This study utilized the Unified Theory of Acceptance and Use of Technology (UTAUT) model to analyze the adoption and utilization of field incident management system (IMS) in a manufacturing organization. The study specifically focused on the role of behavior as a key factor in the adoption and utilization of incident management system. Data was collected...

Due to the demand for IoT technologies, the concept of CPS was explored in this paper. CPS refers to the coordination and communication of physical processes and computing elements connecting the physical and digital worlds. With the increasing number of smart buildings, the researchers considered the automation control of various facilities in a smart building...

This paper attempts to describe the signifier choice of student artists in thematic representations of digital visual arts and determine its implications for digital pedagogy. Utilising a qualitative approach to research and covering a corpus of six digital artworks of student artists, the semiotic analysis utilising Peirce’s (1991) sign modes showed the student artists’ preference...

The onset of the COVID-19 pandemic showed how food supply could become unstable when lockdowns and curfews hamper transportation and delivery logistics. Difficulties arose in producing and selling agricultural products (e.g., vegetables, fruits, meats, and others). Supermarkets had limited or no stock of food supplies. In other cases, deliveries were postponed or canceled due to...

This study proposed a novel approach to personalized medication management using wearable sensors and IoT (Internet of Things) technology. The aim is to develop a medication reminder system that is tailored to the individual needs of patients, taking into account their specific medication schedules and dosages. The system uses wearable sensors to monitor the patient’s...

Solution concentration and several dip cycles are key factors that determine the thickness and quality of perovskite quantum dot (PQD) films. Dip coating is an effective technique used for depositing solution-processed PQDs in substrates which are common passivation layers in solar cells. The optimum dip-coating parameters for depositing cesium lead halide PQDs on GaAs substrates...

Due to the significant impact of the fault on power systems and the failure of protection devices, power system operators and researchers have given reliability a great deal of consideration. The modern IEC 61850 standard is used recently to improve communication systems in digital substations and allow signals to be shared between the devices. Differential...
