Optimization Control Strategies in Building Energy Management Systems
Due to rising energy demands, the industrial revolution has brought with it a slew of new issues. This phenomenon fosters the development of more resource-efficient control approaches. The building sector has a huge potential to mitigate energy demand using intelligent energy management systems (IEMS) and the concept of the internet of energy (IoE). The IoE combines features of a smart grid and the internet of things (IoT). The IoT refers to internet-based architecture in two ways: communication allows the system to be monitored and controlled in real-time via cloud computing or another internet service. It is proven that the potential of IoE-based building energy management systems (BEMS) will enhance the performance of future building energy utilization. The key idea of BEMS is monitoring and controlling the energy consumption in buildings with the aim of reducing emissions. The design of BEMS has taken into account factors such as efficiency, scalability, robustness, flexibility, and an ability to sense the environment and make decisions autonomously.

Artificial Intelligence Approach of Hosting Capacity Analysis
Distribution network operators face technical and operational challenges in integrating the increasing number of distributed energy resources (DER) with the distribution network. The hosting capacity analysis quantifies the level of DER penetration on the network without violating power supply qualities, such as over voltage, under voltage, transformer and feeder overloading, and protection failures that may be caused due to the high penetration of the DER. Artificial Intelligence (AI) techniques could be a useful tool for quantifying the hosting capacity of the network, real-time monitoring of the DER and network parameters and ensuring quality power supply to the consumers.

Peculiarities of Streamline Flowing of Bodies with Droplets
The gas dynamics of heterogeneous flows with dispersed admixtures in the form of solid particles or liquid droplets has been one of the most rapidly developing areas of the mechanics of multiphase (two-phase) media. This is due to the numerous engineering applications of such flows (steam generators, facilities for the thermal pretreatment of coal, heat exchangers with two-phase working fluid, sand and bead blasting facilities, dust collectors of different types) and their wide distribution in nature (tornados, dust storms, volcanic eruptions, snow, rain). One of the most important classes of two-phase flows is the flow of gas with an admixture of solid particles or droplets near the limiting surfaces and when flowing around bodies and obstacles.

Tool Condition Monitoring of Cutting Capability by Thermography
A Tool Condition Monitoring (TCM) system is presented that automatically classifies tool wear of turning tools into four classes. A cutting tool was monitored with infrared (IR) camera immediately after the cut and in the following 60 s. The Convolutional Neural Network Inception V3 was used to analyse and classify the thermographic images, which were divided into different groups depending on the time of acquisition. Based on classification result, one gets information about the cutting capability of the tool for further machining.

Electric Vehicle Charging Systems
The high-voltage battery is a crucial element for electric vehicles (EVs) traction systems. It is the primary energy source that must be regularly recharged to reach the autonomy declared by the manufacturer. Therefore, an EV charging system is required to ensure the battery charging process.

Hydroponic Cultivation
The increasing demand for food, the lack of natural resources and arable land, and the recent restrictions on energy consumption require an immediate solution in terms of agricultural activities. The soil loss, the crop/soil contamination, and the greenhouse gas emissions were the criteria for the environmental comparison of conventional agriculture and hydroponics. As for resource consumption, the water consumption rates (L/kg), energy consumption rates (kWh), and energy required (kW) were the criteria for comparing conventional agriculture with hydroponics.

Controlling Upper Limb Prostheses Using Sonomyography
A ground-breaking study by Zheng et al. investigated whether ultrasound imaging of the forearm might be used to control a powered prosthesis, and the term “sonomyography” (SMG) was coined by the group. Ultrasound signals have recently garnered the interest of researchers in the area of HMIs because they can collect information from both superficial and deep muscles and so provide more comprehensive information than other techniques. Due to the great spatiotemporal resolution and specificity of ultrasound measurements of muscle deformation, researchers have been able to infer fine volitional motor activities, such as finger motions and the dexterous control of robotic hands.

E-Fuels
Power-to-X (PtX) are fuel production pathways in which electricity is converted into various gaseous or liquid fuels, such as e-hydrogen, e-methanol, e-methane, dimethyl ether (E-DME), e-ammonia, or e-diesel. These fuels are also named electrofuels (e-fuel) or power-to-liquid (PtL) and are mentioned in the Annexes of the RED II amendments as alternative options for the decarbonisation of the transport sector. Some of these molecules still contain carbon atoms, thus producing CO2 when used for energy production. The carbon source for the synthesis of e-fuels has to be carefully analysed to define them really carbon neutral.

Power Electronics and Battery Cooling Methods
The global promotion of electric vehicles (EVs) through various incentives has led to a significant increase in their sales. The prolonged charging duration remains a significant hindrance to the widespread adoption of these vehicles and the broader electrification of transportation. While DC-fast chargers have the potential to significantly reduce charging time, they also result in high power demands that the grid and hence may require local battery energy storage systems (BESS) for peak shaving applications. A high power demand also creates high losses and cooling methods play an important role in overall efficiency, sound pollution, system size, reliability, and lifetime of the system.

Circular Product Readiness Method
Design indicators can be used by companies to track circular design implementation, which can yield insights into their performance and opportunities for improvement. Existing indicator methods either lack depth with regard to circular design, are incomplete, or do not use design semantics.
