IBM Secure Service Container. IBM Secure Service Container is the trusted execution environment available for IBM Z and IBM LinuxONE servers.

History
In 2016 IBM introduced the z Appliance Container Infrastructure ("zACI") feature for the IBM z13, z13s, LinuxONE Rockhopper, and LinuxONE Emperor servers, delivered via a driver (firmware) update (driver level 27). IBM originally conceived its trusted execution environment as best suited for software "appliances," such as its own z/VSE Network Appliance, zAware, and GDPS Virtual Appliance offerings. As IBM improved zACI and broadened its applicability, the company quickly changed its name to IBM Secure Service Container (SSC) when the IBM z14 and LinuxONE Emperor II models launched in 2017.

Details
IBM Secure Service Container consists of a combination of hardware, firmware, and software technologies that are commercially available in recent IBM Z and IBM LinuxONE servers. The hardware and firmware elements are primarily extensions to IBM's PR/SM logical partitioning technologies which are Common Criteria Enterprise Assurance Level (EAL) 5+ certified for separation and isolation. A logical partition (LPAR) type of "SSC" is available, and up to 16 TiB of usable main system memory can be allocated per LPAR (the limit as of the IBM z14 and IBM Emperor II server models introduced in 2017).

IBM also supplies a generalized, open source-based software framework for SSCs in the form of IBM Secure Service Container for IBM Cloud Private and a paired, firmware-based enabling feature. This generalized software framework facilitates running conventional virtual machines (VMs) and Docker containers on Linux within the SSC, without requiring special programming to adapt to SSC architecture. In other words, the IBM Secure Service Container (SSC) is the outer "envelope" within which VMs and software containers (such as Docker containers) run in a highly secure, trusted execution environment.

IBM uses SSCs to host many of its own public cloud services, including IBM Cloud Hyper Protect Services. First adopters of IBM SSC technologies include organizations with extremely demanding security requirements, including digital asset and cryptocurrency firms such as Digital Asset Custody Services (DACS). Most organizations using IBM Secure Service Container also rely heavily on the services that IBM's FIPS 140-2 Level 4 certified Crypto Express hardware security modules and Trusted Key Entry (TKE) equipment provide, although these IBM Z and IBM LinuxONE system features can also be used separately, on their own.

Gold(III) sulfide. Gold(III) sulfide or auric sulfide is an inorganic compound with the formula . Auric sulfide has been described as a black and amorphous solid. Only the amorphous phase has been produced, and the only evidence of existence is based on thermal analysis.

Claims
Early investigations claimed to prepare  auric sulfide by the reaction of lithium tetrachloroaurate with hydrogen sulfide:

Similar preparations via chloroauric acid, auric chloride, or gold(III) sulfate a claimed proceed in anhydrous solvents, but water evinces a redox decomposition into metallic gold in sulfuric acid:

Conversely, it is claimed that cyclo-octasulfur reduces gold(III) sulfate to a mixture of gold sulfides and sulfur oxides:

Auric sulfide has also been claimed as the product when auric acetate is sonicated with cyclo-octasulfur in decalin.

Auric sulfide is claimed to react with nitric acid as well sodium cyanide.  It is claimed to dissolve in concentrated sodium sulfide solution.

Heywood interconnector. The Heywood interconnector is a 275 kV AC overhead electricity transmission line with two circuits connecting the electricity grids in South Australia and Victoria, two states of Australia. Both are part of the National Electricity Market. The nominal capacity of the interconnector is 650 MW since an upgrade in 2016. The interconnector was commissioned in 1988 and was the first connection between the two state electricity grids.

Routing 
The Victorian end of the interconnector is the substation at Heywood. The South Australian end is the South East substation near Mount Gambier. When constructed, the Heywood Interconnector project created the new 275 kV links from South East substation through the Tailem Bend substation to the Para Substation at Gould Creek on the outskirts of Adelaide as Para was the closest 275 kV substation to Heywood at the time. The 2016 upgrade included a new substation named Black Range at Willalooka (halfway between the South East and Tailem Bend substations) with series compensation to improve transmission efficiency.

Function 
When the Heywood interconnector was built in 1988, the primary purpose was to move cheaper coal-powered electricity from Victoria to South Australia. In later years, it has been used to an increasing degree to transport wind-powered electricity from South Australia to Victoria.

The 2016 South Australian blackout occurred because multiple windfarms reduced power during a major thunderstorm, after a tornado caused multiple towers on transmission lines to collapse. The Heywood interconnector became overloaded, as the missing generation was automatically drawn from Victoria. The tripping of the interconnector lead to an islanding of the SA power system, which fell into a rapid frequency decline.

Asynchrony (game theory). In game theory, asynchrony occurs when gameplay does not proceed in consistently paced rounds. A system is synchronous if agents in a game move in lockstep according to a global timing system, whereas "in an asynchronous system, there is no global clock. The agents in the system can run at arbitrary rates relative to each other."

Tungsten pentafluoride. Tungsten(V) fluoride is an inorganic compound with the formula WF5. It is a hygroscopic yellow solid. Like most pentafluorides, it adopts a tetrameric structure, consisting of [WF5]4 molecules.  In this way, each W center achieves octahedral coordination.

Production
Tungsten(V) fluoride is produced by the reaction of tungsten and tungsten hexafluoride:
W + 5 WF6  →  6 WF5

At room temperature, it disproportionates to the tetra- and hexafluoride:
2 WF5  →  WF4  +  WF6

Tucker armored car. Among the initiatives of American industrialist Preston Tucker during World War II was the Tucker armored car (also known as the Tucker Tiger Tank even though it was not a tank).

Some prototypes of the high-speed armored car were tested, but no operational models were ordered.  
The vehicle was designed with a very powerful V12 engine, so it could travel at  on road and  off road.  The vehicle was conceived as being armed with a primary armament of a  anti-aircraft gun capable of firing 120 rounds per minute, mounted in an aircraft-style spherical gun turret. The turret would have been supplemented by  machine guns on production vehicles. The vehicle was promoted as being so fast it would chase aircraft, allowing it to hit them with more rounds than fixed gun batteries or slower vehicles.

Long after the war, when Tucker faced the Securities and Exchange Commission, Tucker's press agents produced a highly-colored half-hour film entitled Tucker: The Man and his Car for the Commission members. This film implied that the Tucker armored car and the Tucker gun turret, which were never operational weapons, had been important weapons in World War II. Steve Lehto and Jay Leno, who worked to debunk misconceptions about Tucker's career and importance during World War II, attribute the misconceptions to Tucker's promotional movie.

Assembly line feeding problem. The assembly line feeding problem (abbr. ALFP) describes a problem in operations management concerned with finding the optimal way of feeding parts to assembly stations. For this, various cost elements may be taken into account and every part is assigned to a policy, i.e., a way of feeding parts to an assembly line. The most common policies are:
 Line stocking (also: line side stocking, pallet to work-station, etc)
 Boxed-supply (also: Kanban, batch  supply, etc.)
 Sequencing 
 Stationary kitting (also:  indirect supply, trolley to workstation)
 Traveling kitting (also:  indirect supply, kit to assembly line)

These policies differ with respect to the way parts are brought to the line as well as in the way parts are handled before they are brought to the line. E.g., in line stocking, parts are brought to the line directly in the way they are stored in the warehouse. In the other policies, quantities are reduced (boxed supply) and different part variants are sorted in the order of demand (sequencing, stationary, and traveling kitting).

History 
The problem was formally introduced by Bozer and McGinnis in 1992 by means of a descriptive cost model. Since then, many contributions have been made in both, quantitative and qualitative manners. E.g., a more qualitative contribution is done by Hua and Johnson investigating important aspects of the problem, whereas more recent contributions focus rather on quantitative aspects and use mathematical optimization to solve this assignment problem to optimality

Mathematical problem statement 

This model minimizes the costs  when assigning all parts (index:i) to a feeding policy (index:p) at all stations (index:s) , if there is a demand for a part at a station . Using a certain policy at a station  incurs some cost  as well as some other costs  are incurred when a policy is used at any station, .

All assembly line feeding problems of this type have been proven to be NP-hard
