Question: Bluebottle (formerly known as AOS and now as A2) is a modular, object-oriented Operating System with unconventional features, it has automatic and garbage collected memory management and provides soft real-time features and is developed at which science, technology, engineering and mathematics university in the city of Zürich, Switzerland?

full_context: Document 1: Objective-C: Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language used by Apple for the OS X and iOS operating systems, and their respective application programming interfaces (APIs) Cocoa and Cocoa Touch prior to the introduction of Swift.
Document 2: Bartok (compiler): Bartok is an optimizing compiler and managed runtime system for Common Intermediate Language (which .NET languages compile to), being developed by Microsoft Research. It aims to be efficient enough to be usable for writing operating systems. It provides services such as automatic memory management and garbage collection, threading, and marshalling data to and from native code, as well as verification of CIL code. Bartok is written in C#, including the garbage collector. Bartok is being used by Microsoft Research for the implementation of Singularity, a highly-dependable operating system written almost entirely in managed code.
Document 3: OSv: OSv (stylized OS) is a cloud computing focused computer operating system released on September 16, 2013. It is a special-purpose operating system built to run as a guest on top of a virtual machine, thus it does not include drivers for bare-metal hardware. It is a unikernel, designed to run a single Linux executable or an application written in one of the supported runtime environments (such as Java). For this reason, it does not support a notion of users (it's not a multiuser system) or processes - everything runs in the kernel address space. Using a single address space removes some of the time-consuming operations associated with context switching. It uses large amounts of code from the FreeBSD operating system, in particular the network stack and the ZFS file system. OSv can be managed using a REST Management API and an optional command line interface written in Lua.

The current King of Sweden Carl XVI Gustaf is its High Protector.
Document 5: University of St. Gallen: The University of St. Gallen (in German: "Universität St. Gallen") is a research university located in St. Gallen, Switzerland. Established in 1898, it is specialized in the fields of business administration, economics, law, and international affairs. The University of St. Gallen is also known as HSG, which is an abbreviation of its former German name "Handels-Hochschule St. Gallen".
Document 6: ETH Board: The Board of the Swiss Federal Institutes of Technology (ETH Board, German: "Rat der Eidgenössischen Technischen Hochschulen", French: "Conseil des écoles polytechniques fédérales") is the strategic unit elected by the Swiss Federal Council to manage the Swiss Federal Institutes of Technology Domain (ETH Domain).
Document 7: ETH Zurich: ETH Zurich (Swiss Federal Institute of Technology in Zurich; German: "Eidgenössische Technische Hochschule Zürich" ) is a science, technology, engineering and mathematics university in the city of Zürich, Switzerland. Like its sister institution EPFL, it is an integral part of the Swiss Federal Institutes of Technology Domain (ETH Domain) that is directly subordinate to Switzerland's Federal Department of Economic Affairs, Education and Research. The school was founded by the Swiss Federal Government in 1854 with the stated mission to educate engineers and scientists, serve as a national center of excellence in science and technology and provide a hub for interaction between the scientific community and industry.
Document 8: Object-oriented user interface: In computing, an object-oriented user interface (OOUI) is a type of user interface based on an object-oriented programming metaphor. In an OOUI, the user interacts explicitly with objects that represent entities in the domain that the application is concerned with. Many vector drawing applications, for example, have an OOUI – the objects being lines, circles and canvases. The user may explicitly select an object, alter its properties (such as size or colour), or invoke other actions upon it (such as to move, copy, or re-align it). If a business application has any OOUI, the user may be selecting and/or invoking actions on objects representing entities in the business domain such as customers, products or orders.
Document 9: Politecnico di Studi Aziendali: The Politecnico di Studi Aziendali (Polytechnic University of Business Studies), formerly also referred to as Politecnico di Lugano (Polytechnic University of Lugano), is an unaccredited distance learning, proprietary, for-profit university located in Zug, Switzerland (previously: Roveredo, Agno, Lugano) operated by ISSEA SA. Degrees or other qualifications from unaccredited institutions may not be accepted by civil service or other employers. Some unaccredited institutions have formal legal authorization to enroll students or issue degrees, but in some jurisdictions (notably including the United States) legal authorization to operate is not the same as educational accreditation.
Document 10: Huazhong University of Science and Technology: The Huazhong University of Science and Technology (HUST; ) is a public, coeducational research university located in Wuhan, Hubei province, China. As a national key university, HUST is directly affiliated to the Ministry of Education of China. HUST manages Wuhan National Laboratories for Opto-electronics (WNLO) at Wuchang, which is one of the five national laboratories in China.
Document 11: Aqua (user interface): Aqua is the graphical user interface (GUI) and visual theme of Apple's macOS operating system. It was originally based around the theme of water, with droplet-like components and a liberal use of reflection effects and translucency. Its goal is to "incorporate color, depth, translucence, and complex textures into a visually appealing interface" in macOS applications. At its introduction, Steve Jobs noted that "one of the design goals was when you saw it you wanted to lick it".
Document 12: IT University: IT University is a joint department between Chalmers University of Technology and the University of Gothenburg in Sweden. This joint venture offers a great scope for cooperation between researchers with different areas of expertise and academic specialties within the field of information technology.
Document 13: University of Bern: The University of Bern (German: "Universität Bern" , French: "Université de Berne" , Latin: "Universitas Bernensis" ) is a university in the Swiss capital of Bern and was founded in 1834. It is regulated and financed by the Canton of Bern. It is a comprehensive university offering a broad choice of courses and programs in eight faculties and some 150 institutes. With around 17,512 students, the University of Bern is the third biggest University in Switzerland.
Document 14: Open Platform for Robotic Services: The Open Platform for Robotic Services (OPRoS) is an open source platform based on components. It provides an Integrated Development Environment (IDE) for developing components and monitoring robots, a robot framework for controlling the components in the robot and managing their faults, a simulator for simulation of components and contents, a server for managing the component repository and agents for execution of the proxy services instead of the components in the robot, and a test and evaluation system for components, contents, and developed SW. Especially, The IDE consists of Component Editor, Component Composer, and Task Editor. OPRoS was started in 2007, the source code has been available since August 2009.
Document 15: Bluebottle OS: Bluebottle (formerly known as AOS and now as A2) is a modular, object-oriented Operating System with unconventional features. It has automatic and garbage collected memory management and provides soft real-time features and is developed at ETH Zurich. It is the next generation Native Oberon, the Oberon operating system for bare PC hardware. It is small and fast and supports multiprocessor computers. It is completely based on an upward-compatible dialect of the Oberon programming language called Active Oberon. Its user interface supports a "point-and-click" metaphor to execute commands from text, similar to clicking hyperlinks in a browser. The interface is a zooming user interface. More and detailed information can be found in the Russian wikipedia article about A2 (operating system).
