Surface Charge Accumulation on Insulators in DC GILs
Gas-insulated power transmission lines (GILs) can replace cables and overhead transmission lines, playing an important role in DC transmission systems. However, the influence of surface charge accumulation on insulation reliability cannot be ignored as the operational voltage of the DC GIL increases.

Brazil’s Formal E-Waste Recycling System
Disruptive innovation has led to the increased obsolescence and accelerated replacement of electrical and electronic equipment, resulting in the rapid growth of waste electrical and electronic equipment (e-waste) worldwide. However, amidst the challenges in e-waste management, the recovery of secondary raw materials from e-waste presents an attractive business opportunity.

E-Commerce User Experience in the Last-Mile Delivery
The role of last-mile delivery implies the complexity of managing the flood of parcels in cities, along with the demands for and complexity of omnichannel retailing. The last-mile delivery process involves different stakeholders, such as consumers, logistics providers, and retailers. The last-mile delivery concept presents a chain of storage and transport process steps. Each chain starts at the depot and ends with a handover element. The process chain consists of one or multiple transport and storage process steps moving the shipments closer to the customer. Customer experience in the last-mile delivery process can be a key factor in a customer’s decision to return to the same retailer or brand. Customers are increasingly looking for reliable delivery, as well as flexibility in choosing the time and place of delivery. For this reason, retailers and logistics service providers (courier services) need to focus on providing an efficient and quality experience in the last-mile delivery process to meet customer needs and maintain competitiveness. In addition, the user experience in the product delivery process plays a key role in increasing the user satisfaction.

Postal Digital Transformation Dynamics
The system dynamics approach revealed that the postal sector can be described as a complex phenomenon due to intricate interdependent variables that interact in a dynamic setting. The complex nature of the postal sector is further amplified by multiple feedback systems of non-linear relations.

Methanol as a Biochemical and Bioenergy Carrier
There is a growing interest in the production of biofuels and biochemicals from renewable biomass. Biomass in the form of woody and agricultural residues, municipal solid waste and other organic refuse is becoming popular as a feedstock for biofuel and biochemical production through thermochemical and biological routes. Methanol, a widely used industrial chemical, also has clean fuel properties due to its high-octane number, low flammability, low emissions and high engine performance.

Types of High-Temperature Fixed-Bed Particle Solar Receivers
Among a large number of receivers, the fixed-bed Particle Solar Receiver (PSR) represents a new pathway to high temperature with maximum overall thermal efficiency. The incoming solar radiation can penetrate deeper into the fixed-bed PSR filled with semi-transparent quartz and ceramic particles (spheres or Raschig rings), resulting in an increased volumetric effect. The semi-transparent PSR is full of the quartz glass spheres and/or quartz glass Raschig rings with smooth surfaces for high-temperature applications. The opaque PSR utilizes the ceramic material (e.g., silicon carbide, zirconium oxide and aluminium oxide) or a high-temperature alloy as heating particles. The mixed PSR is defined as a PSR that is full of mixed particles with various optical performances, namely, some quartz glass particles and other opaque particles.

Secure Sensor Prototype in a Blockchain Application
The security of Industrial Internet of Things (IIoT) systems is a challenge that needs to be addressed immediately, as the increasing use of new communication paradigms and the abundant use of sensors opens up new opportunities to compromise these types of systems. In this sense, technologies such as Trusted Execution Environments (TEEs) and Hardware Security Modules (HSMs) become crucial for adding new layers of security to IIoT systems, especially to edge nodes that incorporate sensors and perform continuous measurements.

Product Engineering Modelling in Aesthetic Design Education
By progressively embracing the general principles of integrated, parametric, interdisciplinary design that considers the manufacturing elements of the imagined product, the modern aesthetic designer is called upon to broaden their knowledge and abilities. Especially when there is a need to produce complex shapes, when cost-effective, there are also numerous 3D printing technologies available today, to be used both in the conceptual phase (prototyping) and for actual production.
