Satisfaction Equilibrium
In game theory, a satisfaction equilibrium is a solution concept for a class of non-cooperative games, namely games in satisfaction form. Games in satisfaction form model situations in which players aim at satisfying a given individual constraint, e.g., a performance metric must be smaller or bigger than a given threshold. When a player satisfies its own constraint, the player is said to be satisfied. A satisfaction equilibrium, if it exists, arises when all players in the game are satisfied.

Minix 3
MINIX 3 is a small, Unix-like operating system. It is published under a BSD-3-Clause[lower-alpha 1] license and is a successor project to the earlier versions, MINIX 1 and 2. The project's main goal is for the system to be fault-tolerant by detecting and repairing its faults on the fly, with no user intervention. The main uses of the system are envisaged to be embedded systems and education. (As of 2017), MINIX 3 supports IA-32 and ARM architecture processors. It can also run on emulators or virtual machines, such as Bochs, VMware Workstation, Microsoft Virtual PC, Oracle VirtualBox, and QEMU. A port to PowerPC architecture is in development. The distribution comes on a live CD and does not support live USB installation. MINIX 3 is believed to have inspired the Intel Management Engine (ME) OS found in Intel's Platform Controller Hub, starting with the introduction of ME 11, which is used with Skylake and Kaby Lake processors. It was debated that MINIX could have been the most widely used OS on x86/AMD64 processors, with more installations than Microsoft Windows, Linux, or macOS, because of its use in the Intel ME. The project has been dormant since 2018, and the latest release is 3.4.0 rc6 from 2017, although the MINIX 3 discussion group is still active.

Camp Lazlo
Camp Lazlo (stylized as CAMP LAZLO!) is an American animated television series created by Joe Murray for Cartoon Network. It was produced by Cartoon Network Studios. The show revolves around Lazlo, a spider monkey who attends a Boy Scout-like summer camp with a cast of anthropomorphic animal characters. The series has a style of humor similar to the Nickelodeon series Rocko's Modern Life (which Murray also created and is most known for) SpongeBob SquarePants and The Powerpuff Girls. The series premiered on Cartoon Network on July 8, 2005 at 8:00 p.m. ET/PT with five seasons, 61 episodes, and an hour-long television special. During its run, the series won three Emmy Awards and three Pulcinella Awards, and was also nominated for another Emmy and an Annie Award.

Lempel-Ziv Complexity
The Lempel-Ziv complexity is a measure that was first presented in the article On the Complexity of Finite Sequences (IEEE Trans. On IT-22,1 1976), by two Israeli computer scientists, Abraham Lempel and Jacob Ziv. This complexity measure is related to Kolmogorov complexity, but the only function it uses is the recursive copy (i.e., the shallow copy). The underlying mechanism in this complexity measure is the starting point for some algorithms for lossless data compression, like LZ77, LZ78 and LZW. Even though it is based on an elementary principle of words copying, this complexity measure is not too restrictive in the sense that it satisfies the main qualities expected by such a measure: sequences with a certain regularity do not have a too large complexity, and the complexity grows as the sequence grows in length and irregularity. The Lempel-Ziv complexity can be used to measure the repetitiveness of binary sequences and text, like song lyrics or prose. Fractal dimension estimates of real-world data have also been shown to correlate with Lempel-Ziv complexity.

Lustre (File System)
Lustre is a type of parallel distributed file system, generally used for large-scale cluster computing. The name Lustre is a portmanteau word derived from Linux and cluster. Lustre file system software is available under the GNU General Public License (version 2 only) and provides high performance file systems for computer clusters ranging in size from small workgroup clusters to large-scale, multi-site systems. Since June 2005, Lustre has consistently been used by at least half of the top ten, and more than 60 of the top 100 fastest supercomputers in the world, including the world's No. 1 ranked TOP500 supercomputer in June 2020, Fugaku, as well as previous top supercomputers such as Titan and Sequoia. Lustre file systems are scalable and can be part of multiple computer clusters with tens of thousands of client nodes, tens of petabytes (PB) of storage on hundreds of servers, and more than a terabyte per second (TB/s) of aggregate I/O throughput. This makes Lustre file systems a popular choice for businesses with large data centers, including those in industries such as meteorology, simulation, oil and gas, life science, rich media, and finance. The I/O performance of Lustre has widespread impact on these applications and has attracted broad attention.

Virtual Reality Games in Cultural Heritage
The use of Virtual Reality (VR) games in cultural heritage has been growing. VR Games have increasingly found their way into museums and exhibitions, highlighting the increasing cultural value associated with games and the institutionalization of game culture. VR appears to be a very promising technology in facilitating experiences in the field. It offers significant results concerning the types of technologies used, the types of games used, as well as the different types of experiences for the user. Usage of VR games in the cultural heritage area is associated with multiple learning gains, increased visit motivation, and dynamic engagement.
