Self orthogonal trajectories are a family of curves whose family of orthogonal trajectories is the same as the given family. This is a term that is not very widely used.
Most Nazi scientific efforts were guided by military considerations, they were especially fruitful in the areas of rocket propulsion, jet propulsion, and missile guidance. To name a few:
V-1: The first operational, powered, UAV (Unmanned Air Vehicle), first pulse-jet-propelled air craft, first cruise missile.
V-2: The first operational, short range, ballistic missile. It achieved sub-orbital space flight at an altitude of approximately 80 km.
Rheinbote: The second operational, short range, ballistic missile, designed to replace or augment large bore artillery pieces.
Ruhrstahl X-4: The first wire-guided ATA (Air-To-Air) missile, developed & tested, but never deployed.
ME163: The first operational, manned, rocket-propelled air craft.
ME262: The first operational, manned, jet-propelled air craft.
Der Wasserfall (The Waterfall): The first developed, but never deployed, rocket-propelled STA (Surface To Air), guided missile. Today it would be called a SAM.
Henschel Hs 293: The first operational, Anti ship, Rocket-propelled, guided missile (It began as Fritz X, a stand-off, radio-controlled, gliding bomb (also, a first); then the engine was added to allow low altitude delivery and to increase range and stand-off distance.)
Henschel Hs 293D: As above, but television guided (never deployed).
Cyrus McCormick and John Deere changed agriculture with machines that worked well on midwestern prairies.
Poor design processes would be where the design doesn't meet the specification and requirements agreed with the customer. If the customers needs aren't met then that forms bad relations with said customer
polling interrupt is alternative to the vector interrupt ,
it requires that the interrupt handler poll or send a signal to each device in turn in order to find out which one is sent the interrupt request.....

A MAN is a relatively new class of network, it serves a role similar to an ISP, but for corporate users with large LANs.They typically use wireless infrastructure or Optical fiber connections to link their sites.
1.The network size falls intermediate between LANs and WANs. A MAN typically covers an area of between 5 and 50 km diameter. Many MANs cover an area the size of a city, although in some cases MANs may be as small as a group of buildings or as large as the North of Scotland.
2.A MAN (like a WAN) is not generally owned by a single organisation. The MAN, its communications links and equipment are generally owned by either a consortium of users or by a single network provider who sells the service to the users. This level of service provided to each user must therefore be negotiated with the MAN operator, and some performance guarantees are normally specified.
3.A MAN often acts as a high speed network to allow sharing of regional resources (similar to a large LAN). It is also frequently used to provide a shared connection to other networks using a link to a WAN.
Paddle wheels, turned by the flow of water in a stream or river were connected to a main drive shaft, and pulleys of various sizes were used to vary the amount of power needed for individual tasks. The most common use of paddle wheels was probably the manufacture of flour, where wheat was ground between millstones, which were turned by the power of the paddle wheel, but furniture factories and textile mills also took advantage of the free power that was generated by water seeking lower ground.
Steam was also widely used in industry by the early 1900's, and so for the first time, factories didn't necessarily need to be located in flood zones, unless they needed the waterways to transport their products. Also, because of steam's ability to be used anywhere, some of the first cars and trucks were powered by steam as well.

In database management, a flat file is one that holds all the information in a single table.
By contrast, a relational database has two or more tables having a defined relationship to each other.
A flat file is not related to any other table.
Examples
Flat file
You could keep details of a DVD collection in a flat file. Some of the fields might be:
title
date purchased
length
year issued
Relational database
A retail business might have a database with three tables:
products [one record for each type of item for sale]
customers
products&customers [each sale constitutes a record in this table. The table is related (linked) to each of the other two tables]
Tables and files
"Table" is a database term, "file" a computer term. Some database management programs make each table into a separate file. Others store all the tables in a single file.
Gland steam is used in engineering to prevent air from entering the steam chest.
The greatest invention of Mother Nature is rivers. There are many different streams that flow in different orders, some being perennial or intermittent. They all follow different stream drainage patterns and no two are alike. Some of them even contain waterfall which are a breathtaking sight to see.
It doesn't--this is just an urban legend. Pressurized airplanes can usually maintain cabin pressure with one or more windows completely missing, but even if they lost all cabin pressure, the pilots would use oxygen masks and the emergency masks would drop in front of the passengers. Then the airplane would descend to under 10,000 feet where you wouldn't need oxygen.
a freezer is colder and is for storing food
a garage is useful for storing many things and is alot bigger
