For a duplex printer, the `ps-spool-*' and `ps-print-*' commands will insert blank pages as needed between print jobs so that the next buffer printed will start on the right page.

- An Introduction to Duplex Stainless Steels .
- Duplex Stainless Steels and their characteristics.
- Duplex Stainless steels were developed more than 70 years ago in Sweden for use in the sulfite paper industry. Duplex alloys were originally created to combat corrosion problems caused by chloride-bearing cooling waters and other aggressive chemical process fluids. ...
- Called Duplex because of its mixed microstructure with about equal proportions of ferrite and austenite, duplex stainless steels are a family of grades, which range in corrosion performance depending on their alloy content. ...
- The first-generation grades were alloys of chromium, nickel and molybdenum and while they provided good performance characteristics, welds had low toughness due to excessive ferrite, which limited the use of Duplex steel to a few specific applications.
- Coinciding with the 1970's development of offshore gas and oilfields in the North Sea, a second-generation Duplex was introduced and quickly became the Duplex steel of choice. With deliberate addition of nitrogen as an alloying agent, both improved toughness in the heat-affected zones of welds and excellent chloride corrosion resistance was achieved thus quickly becoming the workhorse of stainless steels, accounting for more than 80% of duplex use. ...
- Duplex alloys are essentially a compromise possessing some of the ferritic stress corrosion cracking resistance and much of the superior formability of the common austenitic stainless alloys, at a cost saving over the high nickel alloys.
- The development of the Duplex stainless steels has continued, graded for their corrosion performance depending on their alloy content. Today, modern duplex stainless steel can be divided into four groups:.
- Lean Duplex such as 2304, which contains no deliberate Mo addition; .
- 2205, the work-horse grade accounting for more than 80% of duplex usage; .
- 25 Cr Duplex such as Alloy 255 and DP-3; .
- Super Duplex; with 25-26 Cr and increased Mo and N compared with 25 Cr grades, including grades such as 2507, Zeron 100, UR 52N+, and DP-3W .

- Architecture Studies Done for High-Rate Duplex Direct Data Distribution (D4) Services.
- A study was sponsored to investigate a set of end-to-end system concepts for implementing a high-rate duplex direct data distribution (D4) space-to-ground communications link. ...
- A duplex direct link (uplink plus downlink communication paths) between a low-Earth-orbit spacecraft and a principal-investigator-based autonomous Earth station .
- A hybrid link using both direct and relay services to achieve full duplex capability .
- A dual-mode concept consisting of both a duplex direct link and a space relay duplex link operating independently .
- The service categories shown in columns two and three represent possible D4 service between spacecraft in low Earth orbit and the ground station using two different types of space-based transmitters in both simple duplex and relay configurations. As shown in column two, a duplex link using a single-beam phased array develops an average throughput of 210 Gbits per day, whereas a dual-beam phased array can average 221 Gbits per day (column three). ...
- The dual-mode architecture combines a simplex high-data-rate direct downlink, using the user datagram protocol (UDP) instead of transmission control protocol (TCP), combined with a low-data-rate, full-duplex TCP/IP link using a satellite communications service such as Inmarsat or the Tracking and Data Relay Satellite System (TDRSS) Multiple Access. ...

12. E2Epi | Duplex Mismatch
- e2epi.internet2.edu
- What Is A Duplex Mismatch?.
- A duplex mismatch is a common cause of end-to-end performance problems. ... It is due to a failure in the protocol used to negotiate whether an Ethernet connection can have traffic flowing only in one direction at a time (half-duplex) or in both directions at the same time (full-duplex). It is apparent that a mismatch occurs when one machine is set at full-duplex and another at half-duplex. ...
- When auto-negotiate meets auto-negotiate, the transmission rate is full-duplex; .
- When half-duplex meets auto-negotiate, the rate is half-duplex. ...
- However, when auto-negotiate meets full-duplex, auto-negotiate converts to half-duplex and not, as you would expect, to full-duplex -– the auto-negotiation capability is programmed to assume half-duplex unless it meets another machine set at auto-negotiate.
- If, for any reason, one side believes it is full-duplex, and the other half-duplex, the side that is full-duplex may send packets when the other side is not expecting them, and those packets are dropped. To avoid these problems, a common campus network recommendation is to always force both sides to full-duplex. ...
