Economic Prospects of  Hydrogen Fuel Cell Vehicles
The economic implications of public transportation powered by hydrogen fuel cell has been investigated. Due to the long working period and the high number of daily driven kilometers, the public transportation sector, especially the taxis sector, is considered one of the leading contributors to the energy and environmental problems related to transportation sector. Therefore, there is an urgent need to investigate the expected implications and feasibility of using hydrogen fuel cell technology as a new alternative in taxi fleets.

Economy Car
An economy car is an automobile that is designed for low-cost purchase and operation. Typical economy cars are small (compact or subcompact), lightweight, and inexpensive to buy. Economy car designers are forced by stringent design constraints to be inventive. Many innovations in automobile design were originally developed for economy cars, such as the Ford Model T and the Austin Mini. The alternative approach, other than innovating to build a low-cost car, is to build a stripped-down, no-frills version of a conventional car. Gordon Murray, the Formula 1 and McLaren F1 designer, said when designing his new Murray T.25 city car: "I would say that building a car to sell for six thousand pounds and designing that for a high-volume production, where you have all the quality issues under control, is a hundred times more difficult than designing a McLaren F1, or even a racing car. It is certainly the biggest challenge I've ever had from a design point of view."

Edge Computing for Traffic Characterization
Traffic flow analysis is essential to develop smart urban mobility solutions. Although numerous tools have been proposed, they employ only a small number of parameters. To overcome this limitation, an edge computing solution is proposed based on nine traffic parameters, namely, vehicle count, direction, speed, and type, flow, peak hour factor, density, time headway, and distance headway.

Edge Computing in Manufacturing Industry
The primary goal of edge computing (EC) is to reduce the time required to transfer large amounts of data. With the ability to analyze data at the edge, it is possible to obtain immediate feedback and use it in the decision-making process. However, the implementation of EC requires investments not only in infrastructure, but also in the development of employee knowledge related to modern computing methods based on artificial intelligence. Future research in EC should particularly cover areas where actions require immediate decision making and the processing of big data, such as autonomous control of robots, vehicles, or entire factories. The second area of research should be technologies related to mobile edge computing, for example, telecommunications and all issues related to 5G technology.

Edge Couplers
Silicon photonics has drawn increasing attention since recent decades and is promising to act as a key technology for future daily applications due to its various merits including ultra-low cost, high integration density owing to the high refractive index of silicon and compatibility with current semiconductor fabrication process. Optical interconnects is an important issue in silicon photonic integrated circuits to transmit light and fiber-to-chip optical interconnects is vital in application scenarios like data centers and optical transmission systems. There are mainly two categories of fiber-to-chip optical coupling, that is off-plane coupling and in-plane coupling. Grating couplers work under the former category while edge couplers function as in-plane coupling. In this paper, we mainly focus on edge couplers in silicon photonic integrated circuits. We deliver an introduction to the research background, operation mechanism and design principles of silicon photonic edge couplers. The state-of-the-art of edge couplers is reviewed according to different configurations as to the device structure, identifying the performance, fabrication feasibility and applications. In addition, a brief comparison between edge couplers and grating couplers is conducted. Packaging issue is also discussed and several prospective techniques for further improvements of edge couplers are proposed.
