Battery Management System Application
Electric Vehicles (EV) and Hybrid EV (HEV) use Lithium (Li) ion battery packs to drive them. These battery packs possess high specific density and low discharge rates. However, some of the limitations of such Li ion batteries are sensitivity to high temperature and health degradation over long usage. The Battery Management System (BMS) protects the battery against overvoltage, overcurrent etc., and monitors the State of Charge (SOC) and the State of Health (SOH). SOH is a complex phenomenon dealing with the effects related to aging of the battery such as the increase in the internal resistance and decrease in the capacity due to unwanted side reactions. The battery life can be extended by estimating the SOH accurately.

AlGaN Ultraviolet (UV)-B/-C Lasers
The development of electrically pumped semiconductor diode lasers emitting at the ultraviolet (UV)-B and -C spectral bands has been an active area of research over the past several years, motivated by a wide range of emerging applications. III-Nitride materials and their alloys, in particular AlGaN, are the material of choice for the development of this ultrashort-wavelength laser technology. Despite significant progress in AlGaN-based light-emitting diodes (LEDs), the technological advancement and innovation in diode lasers at these spectral bands is lagging due to several technical challenges.

Smith Electric Vehicles
Smith Electric Vehicles (also known as Smith's) was a manufacturer of electric trucks. The company, founded in 1920 in the north of England, moved its headquarters to Kansas City, Missouri in 2011. In 2015, Smith idled its manufacturing and it ceased all operations in 2017. Smith was a manufacturer of the world's largest range of zero-emission commercial electric vehicles, with gross vehicle weights (GVWs) from 3,500 to 12,000 kilograms (7,700 to 26,500 lb). From 2010 to 2015, the company produced over 800 commercial electric fleet vehicles. Formerly based in Washington, Tyne and Wear, it manufactured vehicles for the European, Canadian, Southeast Asian and US markets. Smith was formerly part of the Tanfield Group, which trades on the London Stock Exchange's Alternative Investment Market. Tanfield established a Delaware corporation, Smith Electric Vehicles US Corp (SEV US Corp), in 2009 to penetrate the North American market. The company headquarters is in Kansas City, Missouri. In March 2010, the US company indicated that it wanted to buy out its UK counterpart. After a poor multi-year trading history, Smith's UK branches were shut down. This included Smith Electric Vehicles (Europe), which was put into administration, and Smith Technologies (which entered liquidation).

Printed Electronics
Printed electronics are manufactured in a process of registering thin functional material (ink) layer combinations on a low-cost substrate that may be recycled and/or naturally degraded in nature. Correspondingly, the manufacturing process is composed of three complementary stages: material selection, printing and post-printing. The materials for the printed electronics are principally inks of conducting, semiconducting or dielectric characteristics and substrates, which are derived from synthetic or natural polymers.  The inks are transferred with a master through direct contact to the substrate in case of contact printing, while they are deposited onto the substrate typically through nozzles in case of non-contact printing. Posterior to the printing process, it is often necessary to conduct sintering/curing in order to reach the desired functional ink and substrate characteristics. The inks, substrate and the printing technology along with the post printing requirements must be carefully evaluated for quality, repeatability and life-time aspects of the yield.

Plug-in Electric Vehicles in France
The adoption of plug-in electric vehicles in the France is actively supported by the French government through a bonus-malus system through which provides subsidies towards the purchase of all-electric vehicles and plug-in hybrids with low CO2 emissions. The government also provides non-monetary incentives; subsidies for the deployment of charging infrastructure; and long term regulations with specific targets. Additionally, France passed a law in December 2019 to phase out sales of cars that burn fossil fuels by 2040. (As of September 2021), there were 687,876 light-duty plug-in electric vehicles in use in France, consisting of 453,143 all-electric passenger cars and commercial vans, and 234,733 plug-in hybrids. Of these, over 50,000 were fully electric light commercial vehicles. The split among type of powertrain is influenced by the rules of the government subsidies, which favors pure electric vehicles over plug-in hybrids. The plug-in passenger car segment attained a market share of 0.5% in 2013, rose to 1.2% in 2015, 2.2% in 2018, and climbed to 2.8% in 2019. Despite the global strong decline in car sales brought by the COVID-19 pandemic, plug-in electric car sales in France during the first six months of 2020 achieved a record sales volume of 65,267 units, and a market share of 9.1%. (As of December 2019), France listed as the world's second largest market after China for light-duty electric commercial vehicles, with a stock of 49,340 utility vans in circulation. The market share of all-electric utility vans attained 1.2% of new vans registered in 2014, rose to 1.8% in 2018, but declined to 1.7% in 2019. The Renault Zoe has led all-electric car sales in France since 2013, and is the country's all-time best selling plug-in electric car with more than 100,000 units registered through June 2020. The electric utility van segment has been led by the Renault Kangoo Z.E. with over 21,000 units sold through February 2019.

Emergency Communication Networks
Emergency communication refers to the communication means and methods needed for the extensive use of various communication resources to support rescues, including emergency rescues, and the necessary communication in the case of natural or manufactured emergencies. Because of the characteristics of disasters, making effective use of limited resources to provide the best communication services is a key problem. Unlike the traditional communication network, the emergency communication network is a complex network, and enables the implementation of emergency rescue activities and provides the primary conditions for the realization of emergency rescue functions. Its network structure has a significant impact on rescue efficiency. In different emergency situations, the demand for emergency communication is different, and the technical means used are different. Emergency communication mainly has the following characteristics: uncertainty of time and place; uncertainty of capacity demand; high degree of timeliness of the emergency communication; complexity of the environment; uncertainty of the degree of damage to the communication network itself; and diversification of information.

CDSSs in cardiac surgery diagnosis
The advances achieved in recent decades regarding cardiac surgery have led to a new risk that goes beyond surgeons’ dexterity; postoperative hours are crucial for cardiac surgery patients and are usually spent in intensive care units (ICUs), where the patients need to be continuously monitored to adjust their treatment. Clinical decision support systems (CDSSs) have been developed to take this real-time information and provide clinical suggestions to physicians in order to reduce medical errors and to improve patient recovery.

Applications of IRS-Assisted UAV Communication
A intelligent reflecting surface (IRS) can intelligently configure wavefronts such as amplitude, frequency, phase, and even polarization through passive reflections and without requiring any radio frequency (RF) chains. It is predicted to be a revolutionizing technology with the capability to alter wireless communication to enhance both spectrum and energy efficiencies with low expenditure and low energy consumption. Similarly, unmanned aerial vehicle (UAV) communication has attained a significant interest by research fraternity due to high mobility, flexible deployment, and easy integration with other technologies. IRS and UAV can combine together to achieve unparalleled opportunities in difficult environments. Both technologies can achieve enhanced performance by proactively altering the wireless propagation through maneuver control and smart signal reflections in three-dimensional space.
