Multi-Criteria Decision Making (MCDM) Methods and Concepts
Multi-criteria decision-making (MCDM) is one of the main decision-making problems which aims to determine the best alternative by considering more than one criterion in the selection process. MCDM has manifold tools and methods that can be applied in different fields from finance to engineering design. This entry aims to provide a survey on the MCDM concept, its applications, main categories, and different methods. The final section provides manifold information and statistics on the published works in the MCDM fields. Some of the main methods are also listed in this section.

Ulteo Open Virtual Desktop
Ulteo Open Virtual Desktop (OVD) was an open-source Application Delivery and Virtual Desktop infrastructure project that could deliver applications or a desktop hosted on a Linux or Windows server to end users. It was an open source alternative to Citrix and VMware solutions and was, as of June 2012, the only presentation virtualization solution supporting both Linux and Windows applications. It was created by Gaël Duval, who previously created Mandriva Linux. The software seems to be withdrawn, website is unavailable.

Internationalized Country Code Top-Level Domain
An internationalized country code top-level domain is a top-level domain in the Domain Name System (DNS) of the Internet. IDN ccTLDs are specially encoded domain names that are displayed in an end user application, such as a web browser, in their language-native script or alphabet, such as the Arabic alphabet, or a non-alphabetic writing system, such as Chinese characters. IDN ccTLDs are an application of the internationalized domain name system to top-level Internet domains assigned to countries, or independent geographic regions. Although the domain class uses the term code, some of these ccTLDs are not codes but full words. For example, السعودية (as-Suʻūdiyya) is not an abbreviation of "Saudi Arabia", but the common short-form name of the country in Arabic. Countries with internationalized ccTLDs also retain their traditional ASCII-based ccTLDs. As of August 2018 there are 59 approved internationalized country code top-level domains, of them at least 47 used. The most used are .рф (Russia) with over 900,000 domains names, .台灣 (Taiwan) with around 500,000 and .中国 (China) with over 200,000 domains. Still as of 2018 around 20 countries using non-Latin script do not have an internationalized country code top-level domain, including Japan .

Artificial Intelligence for Digital Heritage Innovation
Artificial intelligence (AI) is a game changer in many fields, including cultural heritage. It supports the planning and preservation of heritage sites and cities, enables the creation of virtual experiences to enrich cultural tourism and engagement, supports research, and increases access and understanding of heritage objects. Despite some impressive examples, the full potential of AI for economic, social, and cultural change is not yet fully visible.

Building Information Modelling and Project-Lifecycle
The Architecture, Engineering, Construction and Operations (AECO) industry constitutes a cornerstone of a country’s economy and is predicted to account for circa 15% of the World’s Gross Domestic Product (GDP) by 2030. Construction outputs create critical infrastructure and buildings that cumulatively constitute the built environment which provides the basis for society and other industries to flourish; hence, the economic contribution is perhaps greater than the estimated “direction” contribution to the GDP. Annually, the AECO industry is responsible for nearly 40% of the total energy use, 32% of CO2 emissions and 25% of the generated waste in Europe. Furthermore, in many developing countries, the construction industry has undergone substantial fluctuations to accomplish its local economic objectives. As a result, many developing countries’ financial procedures are in the process of improvement. In these countries, construction projects frequently face several time-schedule delays. Furthermore, the industry is faced with numerous productivity issues stemming from the lack of adoption of emerging technologies or concepts such as Building Information Modelling (BIM), blockchain, Internet of Things (IoT) and Industry 4.0. As a result, the construction industry in developing countries does not achieve government goals for society and clients, and a need for developing “overall success construction projects” that are resource-efficient has been underlined in the literature.

6G Cellular Networks
There are continued advances in the internet and communication fields regarding the deployment of 5G-based applications. It is expected that by 2030, 6G applications will emerge as a continued evolution of the mobile network. Blockchain technology is one of the leading supporting technologies predicted to provide a secure and unique network to 6G-enabled devices, transactions, and applications. It is anticipated that the 6G mobile networks will be virtualized, have cloud-based systems, and aim to be the foundation for the Internet of Everything.

Wolfram Alpha
Wolfram Alpha (also styled WolframAlpha, and Wolfram|Alpha) is a computational knowledge engine or answer engine developed by Wolfram Alpha LLC, a subsidiary of Wolfram Research. It is an online service that answers factual queries directly by computing the answer from externally sourced "curated data", rather than providing a list of documents or web pages that might contain the answer as a search engine might. Wolfram Alpha, which was released on May 18, 2009, is based on Wolfram's earlier flagship product Wolfram Mathematica, a computational platform or toolkit that encompasses computer algebra, symbolic and numerical computation, visualization, and statistics capabilities. Additional data is gathered from both academic and commercial websites such as the CIA's The World Factbook, the United States Geological Survey, a Cornell University Library publication called All About Birds, Chambers Biographical Dictionary, Dow Jones, the Catalogue of Life, CrunchBase, Best Buy, the FAA and optionally a user's Facebook account.
