NEOS Server. The NEOS Server is an Internet-based client-server application that provides free access to a library of optimization solvers. Its library of solvers includes more than 60 commercial, free and open source solvers, which can be applied to mathematical optimization problems of more than 12 different types, including linear programming, integer programming and nonlinear optimization.

The server is managed by the Wisconsin Institute for Discovery at the University of Wisconsin-Madison. Most of the solvers are hosted by the University of Wisconsin in Madison, where jobs run on a cluster of high-performance machines managed by the HTCondor software. A smaller number of solvers are hosted by partner organizations: Arizona State University, the University of Klagenfurt in Austria, and the University of Minho in Portugal. The  server was developed in 1996 by the Optimization Technology Center of Argonne National Laboratory and Northwestern University.

Structure 
The NEOS (Network-Enabled Optimization System) project was launched in  at Argonne National Laboratory and Northwestern University to develop a method to share optimization software resources over the Internet. The server went live in 1996, one of the first examples of software as a service.

The NEOS Server is an Internet-based client-server application that provides access to a library of optimization solvers. The server
accepts optimization models described in modeling languages, programming languages, and problem-specific formats. Most of the linear programming, integer programming and nonlinear programming solvers accept input from AMPL and/or GAMS. Jobs can be submitted via a web page, email, XML RPC, Kestrel or indirectly via third party submission tools  SolverStudio for Excel, OpenSolver, Pyomo, JuMP (through the Julia package NEOS) and the R package rneos. NEOS uses the HTCondor software to manage the workload on a dedicated cluster of computers.

USNS John Lewis. USNS John Lewis (T-AO-205) is a United States Navy replenishment oiler and the lead ship of  her class. She is part of the Military Sealift Command fleet of support ships.

Ray Mabus, then Secretary of the Navy, announced on 6 January 2016 that the ship would be named in honor of John Lewis. Lewis was a civil rights leader and a United States representative from 1987 to 2020.

Construction

Construction was authorized for the first six ships in the class on 30 June 2016. National Steel and Shipbuilding Company began construction of John Lewis on 20 September 2018, with completion scheduled for November 2020. 

The John Lewis class will be equipped with a basic self-defense capability, including crew-served weapons, degaussing, and AN/SLQ-25 Nixie torpedo decoys, and has space, weight, and power reserves for close-in weapon systems (CIWS) such as SeaRAMs.

She was christened on 17 July 2021, the first anniversary of Lewis's death. After completing sea trials with the Navy's Board of Inspection and Survey, John Lewis entered non-commissioned U.S. Navy service under the control of the Military Sealift Command on 27 July 2022.

Rescue of stranded sailor
On 12 December 2022 while traversing from Pearl Harbor to San Diego, John Lewis received a distress call approximately  south of San Diego and  west of the coast of Mexico. A  sailboat had suffered damage with torn sails and had been drifting for five days. Once the sailor was located, he was checked by the medical crew, then fed and clothed. The sailor was then transported to San Diego, where he did not require hospitalization.

Anti-Aircraft Target Rocket M2. The Anti-Aircraft Target Rocket M2 was a  rocket developed and used by the United States Army during World War II. It was designed to serve as a training target for anti-aircraft guns, capable of simulating attacks by low-flying aircraft. The nosecone of the rocket was ogival, and it was fitted with oversized fins to aid in tracking of the rocket by trainees. 

Shipped with two to three rockets in a package, the Target Rocket Projector M1 was used for the rocket's launching platform. It consisted of a set of launching rails on a two-wheeled trailer and weighed ; capable of being elevated to 60 degrees, it allowed the rocket to be launched at random angles and directions to increase the effectiveness of the training exercises, and could fire up to two rounds per minute. A modification of the basic rocket, designated as the Anti-Aircraft Training Rocket M2A1, replaced the basic M2 in service; it added a flare that ignited on launch to aid in visual tracking of the target that burned for approximately 30 seconds after launch.

Zener ratio. The Zener ratio is a dimensionless number that is used to quantify the anisotropy for cubic crystals. It is sometimes referred as anisotropy ratio and is named after Clarence Zener. Conceptually, it quantifies how far a material is from being isotropic (where the value of 1 means an isotropic material).

Its mathematical definition is

where  refers to Elastic constants in Voigt notation.

Cubic materials
Cubic materials are special orthotropic materials that are invariant with respect to 90° rotations with respect to the principal axes, i.e., the material is the same along its principal axes. Due to these additional symmetries the stiffness tensor can be written with just three different material properties like

The inverse of this matrix is commonly written as

where  is the Young's modulus,  is the shear modulus, and  is the Poisson's ratio. Therefore, we can think of the ratio as the relation between the shear modulus for the cubic material and its (isotropic) equivalent:

Universal Elastic Anisotropy Index
The Zener ratio is only applicable to cubic crystals. To overcome this limitation, a 'Universal Elastic Anisotropy Index (AU)'  was formulated from variational principles of elasticity and tensor algebra. The AU is now used to quantify the anisotropy of elastic crystals of all classes.

Tensorial Anisotropy Index
The Tensorial Anisotropy Index AT  extends the Zener ratio for fully anisotropic materials and overcomes the limitation of the AU that is designed for materials exhibiting internal symmetries of elastic crystals, which is not always observed in multi-component composites. It takes into consideration all the 21 coefficients of the fully anisotropic stiffness tensor and covers the directional differences among the stiffness tensor groups.

It is composed of two major parts and , the former referring to components existing in cubic tensor and the latter in anisotropic tensor so that   This first component includes the modified Zener ratio and additionally accounts for directional differences in the material, which exist in orthotropic material, for instance. The second component of this index  covers the influence of stiffness coefficients that are nonzero only for non-cubic materials and remains zero otherwise.

where  is the Coefficient of variation for each stiffness group accounting for directional differences of material stiffness, i.e. In cubic materials each stiffness component in groups 1-3 has equal value and thus this expression reduces directly to Zener ratio for cubic materials.

The second component of this index  is non-zero for complex materials or composites with only few or no symmetries in their internal structure. In such cases the remaining stiffness coefficients joined in three groups are not null

Fwupd. fwupd is an open-source daemon for managing the installation of firmware updates on Linux-based systems, developed by GNOME maintainer Richard Hughes. It is designed primarily for servicing the Unified Extensible Firmware Interface (UEFI) firmware on supported devices via EFI System Resource Table (ESRT) and UEFI Capsule, which is supported in Linux kernel 4.2 and later. Previously, the initiation of UEFI firmware updates within an operating system could, on most systems, only be performed using Microsoft Windows or DOS-specific software. ESRT allows the firmware to expose updatable components to the operating system, which can pass a UEFI capsule with updated firmware for processing and installation on the next boot. Updates can be exposed via a command line tool, or within graphical package managers (such as GNOME Software) via a D-Bus interface.

Linux Vendor Firmware Service
The Linux Vendor Firmware Service (LVFS) provides resources and support for helping vendors package their firmware updates to support the use of this framework, and serves as an online repository for obtaining these updates. To provide a test case on systems where ESRT is not yet supported, fwupd is also able to update firmware on the ColorHug color calibrator.

Adoption
Several Linux distributions use fwupd, including:

 Arch from 2017-06-13
 Debian 9 (Stretch) or newer
 Ubuntu 16.04 (Xenial) or newer
 Fedora 22 or newer
 RHEL and CentOS 7.4 or newer
 openSUSE 15.0 or newer

In December 2015, it was revealed that Hughes had been working with a Dell developer to test the system on actual hardware, and that its Dell Edge Gateway product will support firmware servicing via fwupd. Hughes reported that the company was also "considering expanding out the LVFS support to all new models supporting UEFI updates". In August 2018, Lenovo joined the project and provides update support for a wide range of their devices.

In September 2019, Acer joined the project, with initial support for their Aspire A315 model. Starting from December 2019, Google requires that firmware updates can be applied with fwupd for certified Chromebooks.
