Driving Cycles for Estimating Vehicle Emission Levels
Standard driving cycles (DCs) and real driving emissions (RDE) legislation developed by the European Commission contains significant gaps with regard to quantifying local area vehicle emission levels and fuel consumption (FC). The aim of this paper was to review local DCs for estimating emission levels and FC under laboratory and real-world conditions. This review article has three sections.

Driving Mechanisms/Motion of Screw Drive
In recent years, interest in in-pipe robot research has been steadily increasing. This phenomenon reflects the necessity and urgency of pipe inspection and rehabilitation as several pipe networks have become outdated around the globe. In-pipe robots can be divided into several groups in accordance with their locomotion principles, each with its own advantages and best suited application scope. Research on the screw drive in-pipe robot (SDIR) has had a rising trend due to the robot’s simple driving mechanism design and numerous advantages.

DRL-Based Load-Balancing Routing Scheme for 6G Space–Air–Ground Integrated-Networks
Due to the rapid development of air-ground integrated network (SAGIN), satellite communication systems have the advantages of wide coverage and low geographical environment requirements, and are gradually becoming the main competitive technology of 6G. Low Earth orbit (LEO) satellite network has the characteristics of low transmission delay, low propagation loss and global coverage, and its exploration has become the main research object of contemporary satellite communication.

Drone Applications Fighting COVID-19
The non-military use of drones is becoming more widespread, which the media is now increasingly reporting. Drone applications fighting Covid-19 can be divided into different types of groups: surveillance of an area with a visual camera, detection of fever-infected people with a thermal camera, communication with an on-board installed loudspeaker or QR code flag and three different logistic tasks such as transportation of essentials, health products and disinfectants.

Drone Architecture for Crowd Monitoring and Analysis
Crowd monitoring and analysis is an important evolving applications of unmanned aerial vehicle or drones. From preventing stampede in high concentration crowds to estimating crowd density and to surveilling crowd movements, crowd monitoring and analysis have long been employed in the past by authorities and regulatory bodies to tackle challenges posed by large crowds.

Drone Detection and Defense Systems
Drones are small and low-cost unmanned aerial vehicles (UAVs). With the decrease in the cost and size of drones in recent years, their number has also increased exponentially. As such, the concerns regarding security aspects that are raised by their presence are also becoming more serious.

Drone Fault Detection Based on Failure Mode Databases
Drones have become an indispensable component of modern equipment systems, and as the number of components in these systems continues to increase, so does their complexity. Consequently, the requirements for system quality—particularly reliability, maintainability, and functionality—are also becoming increasingly stringent. Sensor data fusion, fault detection, fault-tolerant estimation, and fault-tolerant control are all important means of ensuring UAV safety. Among these methods, researchers tend to place particular emphasis on fault detection, which can be broadly divided into two categories: model-based approaches and data-driven approache.

Drone Scheduling for Emergency Power Material Transportation
Stable material transportation is crucial for quickly restoring power systems after disasters. Drone-based material transportation can bypass the limitations of ground transportation and reduce transportation time. However, the current UAV flight trajectory distribution optimization model cannot meet the needs of emergency relief material distribution in mountainous areas after disasters. Having a sound emergency distribution plan can significantly speed up the recovery of your distribution system.

Drone-Integrated Geographic Information System Technology
Drones, also known as unmanned aerial vehicles (UAVs), have gained numerous applications due to their low cost, ease of use, vertical takeover and landing, and ability to operate in high-risk or hard-to-reach areas. Geographic Information System (GIS) refers to a field of science that involves the study of the lands, features, inhabitants, and phenomena of the Earth. GIS is a comprehensive framework that includes the processes of acquiring, retaining, modifying, examining, and presenting geographical data in an effective and streamlined way.
