Selective Laser Sintering Process
Selective laser sintering (SLS) is a well-established technology that is used for additive manufacturing. Significant efforts have been made to improve SLS by optimizing the powder deposition, laser beam parameters, and temperature settings. The purpose is to ensure homogeneous sintering and prevent geometric and appearance inaccuracies in the manufactured objects.

Energy Optimization Techniques in UAV-Based Cellular Networks
Wireless communication networks have been witnessing unprecedented demand due to the increasing number of connected devices and emerging bandwidth-hungry applications. Although there are many competent technologies for capacity enhancement purposes, such as millimeter wave communications and network densification, there is still room and need for further capacity enhancement in wireless communication networks, especially for the cases of unusual people gatherings, such as sport competitions, musical concerts, etc.  Unmanned aerial vehicles (UAVs) have been identified as one of the promising options to enhance capacity due to their easy implementation, pop-up fashion operation, and cost-effective nature. The main idea is to deploy base stations on UAVs and operate them as flying base stations, thereby bringing additional capacity where it is needed. However, UAVs mostly have limited energy storage, hence, their energy consumption must be optimized to increase flight time.

Microgrid Frameworks
Microgrids technologies are seen as a cost effective and reliable solution to handle numerous challenges, mainly related to climate change and power demand increase. This is mainly due to their potential for integrating available on-site renewable energy sources and their flexibility and scalability. The particularity of microgrids is related to their capacity to operate in synchronization with the main grid or in islanded mode to secure the power supply of nearby end-users after a grid failure thanks to storage solutions and an intelligent control system.

Solid Matrices as a Metal Source
Metal recovery through recycling refers to reprocessing waste into new metal products to reduce greenhouse gas emission levels, conserve natural resources, and manage energy consumption. In Europe, metal recycling in household solid waste is integral to sustainable waste management. Metal supply depends on specific geological, physical, and industrial conditions, so one supply metric does not fit all metals. With waste production, a growing pool of metals is created, a pool of renewable resources that can replace limited metals from enrichment deposits in the geosphere.

Two-Stage Fuzzy Traffic Congestion Detector
This research presents a two-stage fuzzy-logic application based on the Mamdani inference method to classify the observed road traffic conditions. It was tested using real data extracted from the Padua–Venice motorway in Italy, which contains a dense monitoring network that provides continuous measurements of flow, occupancy, and speed. The data collected indicate that the traffic flow characteristics of the road network are highly perturbed in oversaturated conditions, suggesting that a fuzzy approach might be more convenient than a deterministic one.

Operational Business Artifacts and Agility
Agility, a necessary condition for sustainable performance, should be a key competence of organizations in dynamic markets today. Organizations have to move faster than the market around them, both in terms of decision-making and capability development over time, to maintain a competitive advantage. Agility should therefore not only be seen as a tactic, but rather as a strategic goal by itself. Aligning information systems and businesses at the strategic implementation stage (i.e., operational level) is reported to enhance organizational agility. More specifically, reengineering business behaviors as business services, similar to the service-oriented architectural pattern in software design, is also reported to lead to flexibility and agility in organizations, as long as business knowledge is adequately modelled and interfaces between services are clearly defined. Consequently, business artifacts at the operational level of the business, if adequately modelled, represent an operational agility capability of a business.

Intelligent Micro-Cogeneration Systems for Residential Grids
Historical residential grid data were analysed to develop a machine learning-based demand prediction model for electricity and hot water. Thermal energy storage was integrated into the Micro-cogeneration system to enhance flexibility. An optimization model was created, considering efficiency, emissions, and cost while adapting to real-time demand changes. A control strategy was designed for the flexible operation of the Micro-cogeneration system, addressing excess thermal energy storage and resource allocation. The proposed solution’s effectiveness was validated through simulations, with results demonstrating the Micro-cogeneration system’s ability to efficiently address high electricity and hot water demand periods while mitigating power demand failures from renewable energy sources.

Foot Ulcers in Patients with Diabetes
Unawareness of the risk associated with diabetic foot ulcers (DFU) is a significant contributing factor to the mortality of diabetic patients. Evolving technological advancements such as deep learning techniques can be used to predict the symptoms of diabetic foot ulcers as early as possible, which helps to provide effective treatment to DM patients.

Electrochemical Biosensors for Monitoring the Water Quality
Electrochemical biosensors are advantageous analytical devices or tools that convert a bio-signal by biorecognition elements into a significant electrical response. Biosensors have many advantages over the conventional lab-based method, including low costs, portability, fast response time, less usage of reagents, and the capability to continuous monitor the complex wastewater. Such sensors significantly benefit from sensing the minimum level in polluted water, such as wastewater.

The Importance of Photoacoustic Tomography Image Post-Processing
Photoacoustic tomography (PAT) is a promising imaging technique that utilizes the detection of light-induced acoustic waves for both morphological and functional biomedical imaging. However, producing high-quality images using PAT is still challenging and requires further research. Besides improving image reconstruction, an alternative way to address this issue is through image post-processing, which enhances and optimizes the reconstructed PAT image. Image post-processing methods have rapidly emerged in PAT and are proven to be essential in improving image analysis performance.
