Sun-3

Sun-3 is a series of UNIX computer workstations and servers produced by Sun Microsystems, launched on September 9, 1985. The Sun-3 series are VMEbus-based systems similar to some of the earlier Sun-2 series, but using the Motorola 68020 microprocessor, in combination with the Motorola 68881 floating-point co-processor (optional on the Sun 3/50) and a proprietary Sun MMU. Sun-3 systems were supported in SunOS versions 3.0 to 4.1.1_U1 and also have current support in NetBSD and Linux. Models are listed in approximately chronological order. {| class="wikitable" !Model !Codename !CPU board !CPU MHz !Max. RAM

Assessing the Tightly-Baffled, Long-Legged Divertor (TBLLD) concept in TCV

Holger Reimerdes

The Swiss Plasma Center is upgrading the TCV tokamak to test a tightly baffled, long-legged divertor (TBLLD), a novel concept that promises to enhance power exhaust capabilities with minimal modification to the magnetic configuration [1,2]. Simulations using the SOLPS-ITER code indicate that a TBLLD can improve TCV’s power exhaust capability by an order of magnitude compared to the unbaffled configuration [2]. Tight baffling sustains a high poloidal neutral density gradient, thereby, increasing the neutral

Applicability of CIE Supplementary Photometry for Glare Prediction under Colored Daylit Scenes

Marilyne Andersen

In this study, we examined the influence of daylight transmitted through colored glazing on discomfort glare by exposing 56 participants to four daylight conditions with the sun disc visible in their field of view. The conditions varied only in the glazing color (red, blue, green, and neutral) toward the sun while having similar transmittance and glare metric values. Results showed a strong influence of color on glare perception, with more participants reporting glare under red and blue conditions compared

Sun Shines on Architecture

La relation entre l’architecture et le soleil façonne profondément la conception et la construction des bâtiments depuis des millénaires. Pourtant, l’intégration de l’énergie solaire à l’environnement bâti est jusqu’à aujourd’hui resté plutôt marginal. Bien que le soleil ait toujours été là, source d’énergie et de beauté, faut-il attendre l’épuisement des ressources fossiles pour nous tourner véritablement vers lui ? Le manifeste de la Solar Biennale l’affirme : son heure est enfin venue, mais il ne suffit

Linux

Linux (ˈlɪnʊks ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the use and importance of GNU software in many distributions, causing some controversy.

NetBSD

NetBSD is a free and open-source Unix operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems. The NetBSD project focuses on code clarity, careful design, and portability across many computer architectures. Its source code is publicly available and permissively licensed.

Sun-2

The Sun-2 series of UNIX workstations and servers was launched by Sun Microsystems in November 1983. As the name suggests, the Sun-2 represented the second generation of Sun systems, superseding the original Sun-1 series. The Sun-2 series used a 10 MHz Motorola 68010 microprocessor with a proprietary Sun-2 Memory Management Unit (MMU), which enabled it to be the first Sun architecture to run a full virtual memory UNIX implementation, SunOS 1.0, based on 4.1BSD.

Trip to Mars

A spaceship is launched from Earth to Mars. We want its trajectory’s perihelion to correspond to the Earth’s position when it launched, and the aphelion to correspond to Mars’ position when it arrives (see diagram). We consider Earth and Mars to be on circular coplanar orbitals with R_(E)u2004=u20041u2005 AU and R_(M)u2004=u20041.52u2005 AU (1 AU = 1 astronomical unit = average distance from Sun to Earth= 149.6u2005×u200510⁹xa0m). The Earth’s revolution period T_(E) lasts one year. We don’t know the spacesh
