Wind Turbine Blade Fault Diagnosis Method
Wind turbines have shown a maximization trend. However, most of the wind turbine blades operate in areas with a relatively poor natural environment. The stability, safety, and reliability of blade operation are facing many challenges. Therefore, it is of great significance to monitor the structural health of wind turbine blades to avoid the failure of wind turbine outages and reduce maintenance costs.

Orthopedic Implants in Biomaterials Using Additive Manufacturing Technologies
The additive manufacturing (AM) process is used for joining materials to make objects from 3D model data, usually layer upon layer, contrary to subtractive manufacturing methods. This technology plays a significant role in fabricating orthopedic implants, especially parts of hip implants (HI), such as femoral head, stem, neck, polyethylene linear, acetabular shell, and so on, using biomaterials. These biodegradable resources are those that can be utilized as tissue substitutes since they are accepted by live tissues.

Wind Energy Harvesting and Conversion Systems
Wind energy harvesting for electricity generation has a significant role in overcoming the challenges involved with climate change and the energy resource implications involved with population growth and political unrest. Indeed, there has been significant growth in wind energy capacity worldwide with turbine capacity growing significantly. This confidence is echoed in the wind power market and global wind energy statistics. However, wind energy capture and utilisation has always been challenging. Appreciation of the wind as a resource makes for difficulties in modelling and the sensitivities of how the wind resource maps to energy production results in an energy harvesting opportunity. An opportunity that is dependent on different system parameters, namely the wind as a resource, technology and system synergies in realizing an optimal wind energy harvest.

Single-Phase Fault Tolerant Multilevel Inverters Topologies
Multilevel inverters (MLIs) are used in a variety of industrial applications in high- and medium-voltage systems. The modularity, high-power output from medium voltages, and low harmonic content are some of the advantages of MLIs. The reliability of MLIs is quite important. The reliability is affected by different kinds of faults occurring in the MLIs. In MLI circuits, switching devices are the most vulnerable components and have a major involvement in all types of faults. As an outcome, it is necessary to take proper corrective action in the event of a fault.

Grid-Forming Virtual Power Plants
Virtual Power Plants (VPPs) are efficient structures for attracting private investment, increasing the penetration of renewable energy and reducing the cost of electricity for consumers. It is expected that the number of VPPs will increase rapidly as their financial return is attractive to investors. VPPs will provide added value to consumers, to power systems and to electricity markets by contributing to different services such as the energy and load-following services. Grid forming inverters (GFM) are used to connect distributed energy sources and devices into a unique resource and convert it to Alternating Current. GFMs are especially suited to connecting VPPs to the main power grid.

Reuse of Municipal Solid Waste in Construction
Society is highly dependent on natural resources such as rocks (aggregates) and minerals. Although they are an abundant resource on the planet, their recovery is slow in terms of human lifespan, and from this fact, they are considered non-renewable resources. The construction industry currently consumes around 3000 million tons of natural resources annually and is responsible for 34% of greenhouse gas emissions into the atmosphere. An alternative to reduce this over-extraction is the substitution of aggregates and cement for municipal solid waste (MSW), which represents the application of the circular economy principles. This approach and the waste management hierarchy are described, with a focus on the Latin America and the Caribbean situation. MSW is composed of several fractions, such as organic waste, paper, cardboard, metals, plastic, and glass, among other valuable materials. Areas of opportunity for their reuse in the construction industry have been demonstrated worldwide: a) plastics as substitutes for aggregates or reinforcing fibers, or replaced construction elements such as bricks; b) glass in the production of concrete, mortar, and asphalt pavement; c) paper as a hygrothermal and lighting regulator in buildings, among others.

Deep Learning towards Digital Additive Manufacturing
Machine learning is a type of deep learning. First in the machine learning (ML) process is the manual extraction of relevant image characteristics. These characteristics are also used to classify the image according to its particular characteristics. Researchers focused primarily on digital additive manufacturing, one of the most significant emerging topics in Industry 4.0.
