Short-Term Load Forecasting Method
Electricity consumption varies in short-, medium-, and long-term periods, which cover three forecast time horizons. They range, respectively, from one hour to a week, one week to a year, and more than a year. They are based on several factors, such as climate, region, and sector (residential, industrial, commercial). Residential loads consume most of the electricity generated. Short-Term Load Forecasting (STLF) is important for cost reduction, energy savings, fine scheduling, and safety assurance.

Active Distribution Networks with Fault Current Limiters
To cope with the increasing energy demand, power systems, especially distribution networks, face many challenges. These networks have become complex and large, and their stability and reliability are not easy to be handled. The integration of renewable energy resources and at the same time limiting their accompanied high fault currents is one of the approvable suggestions. Many solutions have appeared to restrict the fault currents, but fault current limiters (FCLs) arise as an efficient and promising solution to whether to interrupt or limit the fault currents to allowable limits.

Reconfigurability with Metamaterials
Metamaterials exhibit properties in terms of subwavelength operation or phase manipulation, among others, that can be used in a variety of applications in 5G communication systems. The future and current 5G devices demand high efficiency, high data rate, computational capabilities, cost-effectiveness, compact size, and low power consumption. This variation and advancement are possible when the antenna design is revised to operate over wideband, high gain, and multiband and has characteristics of compact size, reconfiguration, absorption, and simple ease of fabrication. The materials loaded with antennas or, in the same cases, without antennas, offer the aforementioned characteristics to bring advancement in order to facilitate users.

Messaging Queuing Telemetry Transport Characteristics
The Messaging Queuing and Telemetry Protocol (MQTT) is a subscription and publishing service-based communication with a centralized server. MQTT is used in manufacturing industries due to its open-source moldable nature, petroleum and natural gas, health, weather, home automation, smart farming, smart metering, remote, etc. In this research, a QoS-0 based MQTT is developed in such a manner that the transparent MQTT protocol uses Transmission Control Protocol (TCP) based connectivity with various rules for retransmission of contents if the requests are not entertained for a fixed duration. The research explores ways to improve the overall content delivery probability. The parameters are examined over transparent gateway-based TCP network after developing mathematical model for the proposed retransmission based mutant QoS-0.

Versatile Electronics for Microwave Holographic RADAR
The NATO SPS G-5014 project has shown the possibility of using a holographic RADAR for the detection of anti-personnel mines. To use the RADAR on a robotic scanning system, it must be portable, light, easily integrated with mechanical handling systems and configurable in its operating parameters for optimal performance on different terrains. The novel contribution is to use software programmable electronics to optimize performance and to use a time reference to obtain synchronization between the RADAR samples and the position in space, in order to make it easy to integrate the RADAR on robotic platforms.

HH Ferry Route
The HH Ferry route (About the name: Helsingør–Helsingborg; Helsingør is Danish for Elsinore) is a very old shipping route which connects Helsingør on Zealand, Denmark and Helsingborg, Scania, Sweden across the northern, and narrowest part of the Øresund. Due to the short distance, which is less than 3 nautical miles, is it one of the world's busiest international car ferry routes, with around 70 daily departures from each harbour. The oldest-known written mention of the route dates to the German traveller Adam of Bremen in the 11th century, but it has likely been in use much longer. Before 1658, the route was a domestic Danish route. For several centuries, the route has been run regularly by various Danish shipping lines. Its significance grew during the 1950s, but since the inauguration of the Øresund Bridge in 2000, at the southern end of the Øresund, it has lost some significance but remains as one of the world's most important ferry routes, particularly as a cheaper alternative to the bridge tolls. Since 1952, passports have not been required for Scandinavian and Finnish citizens.

Road Anomaly Detection, Deep Learning-Based Methods and Visual-SLAM
The proliferation of autonomous vehicles (AVs) emphasises the pressing need to navigate challenging road networks riddled with anomalies like unapproved speed bumps, potholes, and other hazardous conditions, particularly in low- and middle-income countries. These anomalies not only contribute to driving stress, vehicle damage, and financial implications for users but also elevate the risk of accidents. A significant hurdle for AV deployment is the vehicle’s environmental awareness and the capacity to localise effectively without excessive dependence on pre-defined maps in dynamically evolving contexts.

Graphene Flexible Photodetectors
In recent years, optoelectronics and related industries have developed rapidly. As typical optoelectronics devices, photodetectors (PDs) are widely applied in various fields. The functional materials in traditional PDs exhibit high hardness, and the performance of these rigid detectors is thus greatly reduced upon their stretching or bending.

DC Ultra-Fast Charging Station
The battery charging procedure has different definitions and requirements. One of the most important definitions is the battery C rating. The battery capacity is usually rated at 1C (1C current). A 400 V battery with 100 kWh capacity can be charged or discharged with 250 A within one hour. This means that with the use of 1 kA of current, the battery can be recharged in 15 min. Therefore, an increase in C rating yields a faster charging or discharging time. However, C rate increase has technically some limitations, including increases in internal energy losses, battery thermal tolerance, and reducing battery’s life-cycle. The 6C rate of charging is considered as an ultra-fast charging method according to the US Department of Energy (DOE). As a result, a trade-off exists between ultra-fast charging and battery health. Different possible configurations of DC ultra-fast charging stations are AC-coupled, DC-coupled, and hybrid-coupled.

Thin Film Lithium-Ion Battery
The thin film lithium-ion battery is a form of solid-state battery. Its development is motivated by the prospect of combining the advantages of solid-state batteries with the advantages of thin-film manufacturing processes. Thin-film construction could lead to improvements in specific energy, energy density, and power density on top of the gains from using a solid electrolyte. It allows for flexible cells only a few microns thick. It may also reduce manufacturing costs from scalable roll-to-roll processing and even allow for the use of cheap materials. thumb|right|Lithium Ion Battery

Recycled Silicon and Silicon-Based Thermoelectrics for Power Generation
Silicon is the second most earth-abundant element in the earth’s crust, and the most abundant element used in modern-day technologies. Its popularity partially stems from the nontoxic and relatively unreactive nature of derivatives, such as silica and silicates, at room temperature. Consequently, the sheer volume of silicon being used has accelerated the rate of production of waste materials.
