  Neuroscience For Kids - Explore the nervous system
The peripheral nervous system is divided into two major parts: the somatic nervous system and the autonomic nervous system.
The autonomic nervous system is divided into three parts: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.
The enteric nervous system is a meshwork of nerve fibers that innervate the viscera (gastrointestinal tract, pancreas, gall bladder).

  File system - Wikipedia, the free encyclopedia
File systems may use a storage device such as a hard disk or CD-ROM and involve maintaining the physical location of the files, or they may be virtual and exist only as an access method for virtual data or for data over a network (e.g.
The file system software is responsible for organizing these sectors into files and directories, and keeping track of which sectors belong to which file and which are not being used.
A disk file system is a file system designed for the storage of files on a data storage device, most commonly a disk drive, which might be directly or indirectly connected to the computer.

 Twelve leverage points - Wikipedia, the free encyclopedia
To the degree that the observer is within the system, or "part of it", awareness and manipulation of these levers is an aspect of self-organization.
She started with the observation that there are levers, or places within a complex system (such as a firm, a city, an economy, a living being, an ecosystem, an ecoregion) where a "small shift in one thing can produce big changes in everything" (compare: constraint in the sense of theory of constraints).
She describes a system as being in a certain state, and containing a stock, with inflows (amounts coming into the system) and outflows (amounts going out of the system).

 System and Structure
A system is an internally organised whole where elements are so intimately connected that they operate as one in relation to external conditions and other systems.
Structure is the type of connection between the elements of a whole.
Structure implies not only the position of its elements in space but also their movement in time, their sequence and rhythm, the law of mutation of a process.

 Understanding Federal and State Courts - Educational Outreach
Know the structure of the federal court system and a typical state court system and be able to discuss the similarities and differences between the two.
The federal court system deals with issues of law relating to those powers expressly or implicitly granted to it by the U.S. Constitution, while the state court systems deal with issues of law relating to those matters that the U.S. Constitution did not give to the federal government or explicitly deny to the states.
Most state court systems are made up of (1) two sets of trial courts: (a) trial courts of limited jurisdiction (probate, family, traffic, etc.) and (b) trial courts of general jurisdiction (main trial-level courts); (2) intermediate appellate courts (in many, but not all, states); and (3) the highest state courts (called by various names).

 Anthony Wilden - System and Structure
Both the new structural and the new systemic-cybernetic approach seem in fact to bespeak a veritable epistemological revolution in the life and social sciences, about which we shall be hearing a lot more in the next decade (if we survive it, that is).
And since 'structuralism' is indeed the property of a class, then we may correctly identify it as a system of ideological rationalization - which is not the same, however, as saying that it has no value.
Lévi-Strauss's mistaken analogy between a context-free system and a context-bound system - and all the subsequent edifice erected on it by the structuralists - is derived from a confusion between language and communication.

 CSC 3453 File System Structure   (Site not responding. Last check: 2007-10-18)
The superblock describes the filesystem; this enables the file system task (or another operating system, like Linux) to identify the filesystem and determine where important data are found in the partition.
When a partition is mounted using the mount() system call, the file system tasks reads the partition's superblock from disk and kept in memory so it can determine where to find important blocks in the partition.
At boot time, the file system task retrieves the superblock for the root partition (which is identified in the kernel's data).

The Top Level Structure of the Domain Names In the Domain Name System (DNS) naming of computers there is a hierarchy of names.
In the country TLDs, there is a wide variation in the structure, in some countries the structure is very flat, in others there is substantial structural organization.
In the case of top-level domains that are country codes this means that there is a manager that supervises the domain names and operates the domain name system in that country.

 Understanding the Federal Courts   (Site not responding. Last check: 2007-10-18)
The structure of the federal court system has varied a great deal throughout the history of the nation.
The Constitution merely provides that the judicial power of the United States "be vested in one Supreme Court, and in such inferior courts as Congress may from time to time ordain and establish." Thus, the only indispensable court is the Supreme Court.
If the federal court system is viewed as a pyramid, at the top is the Supreme Court of the United States, the highest court.

A speech recognition system according to claim 8, wherein said dictionary is composed of names of places, roads, structures, gasoline service stations, convenience stores, and family restaurants which exist in any or designated area of said plurality of areas, and the number of words of each area being limited to a certain number.
The speech recognition system may be used in a car navigation system and may be constructed such that when any number or designated number of words or sentences made an object of speech recognition are prepared and defined as a dictionary.
For example, in a car navigation system, the dictionary is the assembly of words which include the names of roads, places, structures and streets, street numbers, and the names of intersections, gasoline service stations, convenience stores, family restaurants and so forth and words which are required for necessary and minimum conversations.

 System control structure of the IBM eServer z900
System control is therefore increasingly delegated to a set of other “little helpers” in the system outside the scope of the operating systems.
A requirement known from previous systems is that the hardware has to keep its steady state; i.e., all of the output devices must retain their state, even if the code is no longer running.
The system structure of the hardware management for z900 systems [2] establishes the SE platform as a firewall between the service network and any outside network.

 Management System Structure   (Site not responding. Last check: 2007-10-18)
To assist this, each of these areas must structured in such a way that the structure helps to drive implementation as well as improvement of activities vital to the control of risk.
The structure starts with a need assessment, management statement and coordination, then goes to the establishment of the standing plan for the activity/attention area concerned and ends with assessment of activities, evaluation of results and the periodic review and improvement.
The generic structure can be seen as an extension of the Deming circle PDCA (Plan - Do - Check - Act) as well as an application of the model that I use to demonstrate the main ingredients for success.

 darwiche98a Abstract   (Site not responding. Last check: 2007-10-18)
Abstract: This paper presents a comprehensive approach for model-based diagnosis which includes proposals for characterizing and computing preferred diagnoses, assuming that the system description is augmented with a system structure (a directed graph explicating the interconnections between system components).
We show that if the system structure does not contain cycles, then there is always a linear-size consequence in NNF which can be computed in linear time.
For arbitrary system structures, we show a precise connection between the complexity of computing consequences and the topology of the underlying system structure.

 OAA System Structure
Figure 1 presents the structure typical of a small OAA system, showing a user interface agent and several application agents and meta-agents, organized as a community of peers by their common relationship to a facilitator agent.
In many systems, the facilitator is also used to provide a global data store for its client agents, which allows them to adopt a flboard style of interaction.
In some systems, this agent is implemented as a collection of ``micro-agents'', each monitoring a different input modality (point-and-click, handwriting, pen gestures, speech), and collaborating to produce the best interpretation of the current inputs.

 Implementing an Operating System > 1 System Structure   (Site not responding. Last check: 2007-10-18)
If a system is worried about data being corrupted in transit, it should arrange for each file to be checksummed at the time it is written and the checksum stored along with the file.
However, by starting with a minimal system consisting of little more than a protection mechanism and then adding protected modules to the kernel one at a time until reaching the functionality desired, a minimal system can be built for the application at hand.
In fact, the kernel itself can be structured entirely of such threads, so that when a user does a system call, instead of the user's thread executing in kernel mode, the user's thread blocks and passes control to a kernel thread that takes over to do the work.
