Battery Charging Techniques for Unmanned Aerial Vehicles
Unmanned Aerial Vehicles (UAVs) are intended to be controlled remotely, either through predefined trajectories or through a radio controller. UAVs are now essential components in both civilian and military applications. UAVs, on the other hand, are energy-hungry devices that deplete batteries within minutes of operation. Due to limited battery capacity, UAVs have short flight times.

Fresh Fish Preservation
Fresh fish is a highly perishable food characterized by a short shelf-life, and for this reason, it must be properly handled and stored to slow down its deterioration and to ensure microbial safety and marketable shelf-life. Modern consumers seek fresh-like, minimally processed foods due to the raising concerns regarding the use of preservatives in foods, as is the case of fresh fish. Given this, emergent preservation techniques are being evaluated as a complement or even replacement of conventional preservation methodologies, to assure food safety and extend shelf-life without compromising food safety.

Biofuel production from different sources
Due to the depletion of fossil fuels, biofuel production from renewable sources has gainedinterest. Malaysia, as a tropical country with huge resources, has a high potential to produce differenttypes of biofuels from renewable sources. In Malaysia, biofuels can be produced from various sources,such as lignocellulosic biomass, palm oil residues, and municipal wastes. Besides, biofuels are dividedinto two main categories, called liquid (bioethanol and biodiesel) and gaseous (biohydrogen andbiogas). Malaysia agreed to reduce its greenhouse gas (GHG) emissions by 45% by 2030 as theysigned the Paris agreement in 2016. Therefore, we reviewed the status and potential of Malaysia asone of the main biofuel producers in the world in recent years. The role of government and existingpolicies have been discussed to analyze the outlook of the biofuel industries in Malaysia.

Digital Applications in Energy Sector
Digitalization is a transformation process which has already affected many parts of industry and society and is expected to yet increase its transformative speed and impact. In the energy sector, many digital applications have already been implemented. However, a more drastic change is expected during the next decades. Good understanding of which digital applications are possible and what are the associated benefits as well as risks from the different perspectives of the impacted stakeholders is of high importance. On the one hand, it is the basis for a broad societal and political discussion about general targets and guidelines of digitalization. On the other hand, it is an important piece of information for companies in order to develop and sustainably implement digital applications. This entry provides a structured overview of potential digital applications in the German energy (electricity) sector on the basis of a literature review.

BMW 5 Series Gran Turismo
The BMW 5 Series Gran Turismo (also referred to as "5 Series GT") models are the 5-door fastback versions of the F10 5 Series model range and use the model code F07. The F07 uses the F10 platform and shares many components with the other 5 Series models. It was released in 2009. Engine choices were turbocharged straight-6 petrol, straight-6 diesel and V8 petrol. At launch, all models were rear-wheel drive ("sDrive"), with all-wheel drive ("xDrive") models being added in 2010. For the following G30 generation, the Gran Turismo models were moved to the 6 Series model range and renamed the G32 6 Series Gran Turismo.

Continuous Casting Practices for Steel
Continuous casting practices for steelmaking have been constantly evolving ever since the early 1930s, when Junghans was first researching ways to pour liquid steel into an open-bottomed, water-cooled mold, to withdraw the partially solidified steel out of it, continuously, in the form of a round or square billet or slab. He envisioned that once these continuously cast shapes had become fully frozen, their solidified ends could be cut off for further processing. In this way, they could be transformed into “rebar” to reinforce concrete, or into bars from which nails, bolts, tire cord wire, etc., could be fashioned, etc. However, long before that, Sir Henry Bessemer had proposed a far more elegant approach, involving two, contra-rotating rolls, into which liquid steel is poured, to produce a thin solidified sheet of steel directly, within a few milliseconds. This is referred to as a Near Net Shape Casting Process. After 150 years of trying, CASTRIP, a subsidiary of NUCOR, BHP, and IHI, made this process a commercial success, where many previous attempts had failed. However, there is an even better NNSC process, referred to as HSBC, or "Horizontal Single Belt Casting", that has also been commercially successful. The HSBC process is capable of casting many different grades of steel, unlike the Bessemer CASTRIP process, by casting ~10 - 15mm thick strips, that can then be rolled down to a final sheet ~1.5 - 0.5mm. thickness, in a one-step continuous process.

Financial Assessment of Renewable Energy Projects
Financial assessment of renewable energy projects is to help decision-makers invest in renewable energy sources (RES) technologies, it is essential to have reliable indicators capable of measuring a project’s total performance. Despite the global increase in renewable energy sources (RES) investments associated with economic and population growth, few studies have presented a comprehensive evaluation mechanism for RES projects, mainly due to the multiplicity of variables capable of influencing the viability of these endeavors. Therefore, building models that allow an efficient and holistic measurement is a difficult task.

Types of Steel Liners
There are significant levels of concern about both the safety assessment and financial evaluation of the whole hydropower system, especially at early project stages. In addition, there is a variety of reliable and accurate methods for analysis, design, and optimization of steel pressure liners in hydropower plants. Several countries have developed specific regulations and codes for the design, installation, and safety evaluation of under-pressure piping, as well as estimates of the potential risks associated with failure. This article reviews the current methodologies and codes available for design and safety assessment of either unstiffened or stiffened pressure steel liners in hydropower plants.
