Operative Forecasting of Electric Energy Consumption
Balancing the production and consumption of electricity is an urgent task. Its implementation largely depends on the means and methods of planning electricity production. Forecasting is one of the planning tools since the availability of an accurate forecast is a mechanism for increasing the validity of management decisions. Both classical and modern forecasting methods have been identified when forecasting electric energy consumption. Classical forecasting methods are based on the theory of regression and statistical analysis (regression, autoregressive models); probabilistic forecasting methods and modern forecasting methods use classical and deep-machine-learning algorithms, rank analysis methodology, fuzzy set theory, singular spectral analysis, wavelet transformations, Gray models, etc. Operational forecasting is the research subject of many scientists; it touches upon the issues of operational management of the operating modes of power facilities.

The Lean Blowout Prediction Techniques
The lean blowout is the most critical issue in lean premixed gas turbine combustion. Decades of research into LBO prediction methods have yielded promising results. Predictions can be classified into five categories based on methodology: semi-empirical model, numerical simulation, hybrid, experimental, and data-driven model.

U-Boat Campaign
The U-boat Campaign from 1914 to 1918 was the World War I naval campaign fought by German U-boats against the trade routes of the Allies. It took place largely in the seas around the British Isles and in the Mediterranean. The German Empire relied on imports for food and domestic food production (especially fertilizer) and the United Kingdom relied heavily on imports to feed its population, and both required raw materials to supply their war industry; the powers aimed, therefore, to blockade one another. The British had the Royal Navy which was superior in numbers and could operate on most of the world's oceans because of the British Empire, whereas the Imperial German Navy surface fleet was mainly restricted to the German Bight, and used commerce raiders and unrestricted submarine warfare to operate elsewhere. In the course of events in the Atlantic alone, German U-boats sank almost 5,000 ships with nearly 13 million gross register tonnage, losing 178 boats and about 5,000 men in combat. Other naval theatres saw U-boats operating in both the Far East and South East Asia, the Indian Ocean and the Mediterranean and North Seas.

Dragon 2
Dragon 2 is a class of reusable spacecraft developed and manufactured by U.S. aerospace manufacturer SpaceX, intended as the successor to the Dragon cargo spacecraft. The spacecraft launches atop a Falcon 9 Block 5 rocket and returns via ocean splashdown. When compared to Dragon, Crew Dragon has larger windows, new flight computers and avionics, redesigned solar arrays, and a modified outer mold line. The spacecraft has two planned variants – Crew Dragon, a human-rated capsule capable of carrying up to seven astronauts, and Cargo Dragon, an updated replacement for the original Dragon. Crew Dragon is equipped with an integrated launch escape system in a set of four side-mounted thruster pods with two SuperDraco engines each. Crew Dragon has been contracted to supply the International Space Station (ISS) with crew under the Commercial Crew Program, with the initial award occurring in October 2014 alongside Boeing CST-100 Starliner. Crew Dragon's first non-piloted test flight to the ISS launched in March 2019. Cargo Dragon will supply the ISS with cargo under the Commercial Resupply Services-2 (CRS-2) after a January 2016 selection alongside Northrop Grumman Innovation Systems' Cygnus and Sierra Nevada Corporation's Dream Chaser. SpaceX's first CRS-2 mission with the Cargo Dragon is slated to occur in August 2020 after SpaceX's final CRS-20 mission with the original Dragon spacecraft. The Crew Dragon capsule that flew in the first test flight was scheduled to be used in a flight abort test before it unexpectedly exploded during a test of its SuperDraco engines on 20 April 2019. An investigation into the explosion was completed on 15 July 2019 and resulted in changes to vehicle plumbing. The in-flight abort test was conducted on 19 January 2020 at 15:30 UTC. The first crewed launch is scheduled for April 2020.

Aeroflot Fleet
The Aeroflot passenger fleet consists of narrow-body and wide-body aircraft from six aircraft families: the Airbus A320, the Airbus A330, the Airbus A350, the Boeing 737, the Boeing 777, and the Sukhoi Superjet 100. As of March 2020, there are 247 passenger aircraft registered in the Aeroflot fleet. For most of its history, Aeroflot's fleet consisted almost entirely of aircraft built by Soviet manufacturers such as Antonov, Ilyushin, and Tupolev. Following the Soviet Union's dissolution and subsequent partition of the airline, Aeroflot began replacing its old Soviet aircraft with modern Western and some new-generation Russian models. Aeroflot's CEO Vitaly Saveliev intends to make its fleet younger in accordance with its corporate strategy to keep the airline competitive with other international airlines.

BeiDou Navigation Satellite System
The BeiDou Navigation Satellite System (BDS) is a Chinese satellite navigation system. It consists of two separate satellite constellations. The first BeiDou system, officially called the BeiDou Satellite Navigation Experimental System and also known as BeiDou-1, consists of three satellites which since 2000 has offered limited coverage and navigation services, mainly for users in China and neighboring regions. Beidou-1 was decommissioned at the end of 2012. The second generation of the system, officially called the BeiDou Navigation Satellite System (BDS) and also known as COMPASS or BeiDou-2, became operational in China in December 2011 with a partial constellation of 10 satellites in orbit. Since December 2012, it has been offering services to customers in the Asia-Pacific region. In 2015, China started the build-up of the third generation BeiDou system (BeiDou-3) in the global coverage constellation. The first BDS-3 satellite was launched on 30 March 2015. As of January 2018, nine BeiDou-3 satellites have been launched. BeiDou-3 will eventually consist of 35 satellites and is expected to provide global services upon completion in 2020. When fully completed, BeiDou will provide an alternative global navigation satellite system to the United States owned Global Positioning System (GPS), and is expected to be more accurate than the GPS. It was claimed in 2016 that BeiDou-3 will reach millimeter-level accuracy (with post-processing), which is ten times more accurate than the finest level of GPS. According to China Daily, in 2015, fifteen years after the satellite system was launched, it was generating a turnover of $31.5 billion per annum for major companies such as China Aerospace Science and Industry Corp, AutoNavi Holdings Ltd, and China North Industries Group Corp.

Wapama (Steam Schooner)
Wapama, also known as Tongass, was a vessel last located in Richmond, California. She was the last surviving example of some 225 wooden steam schooners that served the lumber trade and other coastal services along the Pacific Coast of the United States . She was managed by the National Park Service at San Francisco Maritime National Historical Park until dismantled in August 2013. Wapama was designated a National Historic Landmark in 1984; the designation was withdrawn in 2015.

International Council of Societies of Industrial Design
The International Council of Societies of Industrial Design (Icsid) was founded in 1957 from a group of international organizations focused on industrial design. Today Icsid is a worldwide society that promotes better design around the world, and has since been renamed the World Design Organization in January 2017. Today, WDO includes over 140 member organizations in more than 40 nations, representing an estimated 150,000 designers. The primary aim of the association is to advance the discipline of industrial design at an international level. To do this, WDO undertakes a number of initiatives of global appeal to support the effectiveness of industrial design in an attempt to address the needs and aspirations of people around the world, to improve the quality of life, as well as help to improve the economy of nations throughout the world. WDO holds United Nations Special Consultative Status which empowers them to make change, and works towards addressing the United Nations Sustainable Development Goals.
