Unreferenced date June 2008 Hierarchical modulation , also called layered modulation , is one of the signal processing techniques for multiplexing and modulation modulating multiple data streams into one single symbol stream, where base layer symbols and enhancement layer symbols are synchronously overplayed before transmission. Hierarchical modulation is particularly used to mitigate the cliff effect in digital television broadcast, particularly mobile TV , by providing a lower quality fallback signal in case of weak signals, allowing graceful degradation instead of complete signal loss. It has been widely proven and included in various standards, such as DVB T , MediaFLO , UMB Ultra Mobile Broadband , a new 3.5th generation mobile network standard developed by 3GPP2 , and is under study for DVB H . Hierarchical modulation is also taken as one of the practical implementations of superposition precoding, which can help achieve the maximum sum rate of broadcast channels.

Hierarchical incompetence is the often observed inability of organisations to achieve the aims set for them. This can be due to the over simplification of issues and the loss of tacit knowledge about issues as they ascend a hierarchical organization .There is often an inbuilt tendency for people up the hierarchy to discount information coming from those lower down, particularly if it questions conventional wisdom of the hierarchy. There is a tendency for lateral communication across the various departments, fiefdoms, etc. to be stifled either actively by management, or by self imposed isolation. ref cite book last David first Andrews title The IRG Solution Hierarchical Incompetence and how to overcome it publisher Souvenir Press location London date 1984 pages 200 220 isbn 0285626620 ref Conversely, ref citation url http www.claverton energy.com energy experts library downloads worldenergypolicy The IRG Solution Hierarchical Incompetence and how to overcome it publisher Souvenir Press location London date 1984 pages 200 220 isbn 0285626620 ref the hierarchies only easily deliver simple messages which cascade down to the lower levels.

Hierarchical routing is method of routing in networks that is based on hierarchical addressing. Background Most Transmission Control Protocol Internet Protocol Internet protocol suite TCP IP routing is based on a two level hierarchical routing in which an IP Network address address is divided into a computer network network portion and a Server computing host portion. Gateways use only the network portion until an IP datagram reaches a Gateway computer networking gateway that can deliver it directly. Additional levels of hierarchical routing are introduced by the addition of subnetworks. Description Hierarchical routing is the procedure of arranging routers in a hierarchical manner. A good example would be to consider a corporate intranet . Most corporate intranets consist of a high speed backbone network . Connected to this backbone are routers which are in turn connected to a particular workgroup. These workgroups occupy a unique local area network LAN . The reason this is a good arrangement is because even though there might be dozens of different workgroups, the span of this particular description is only 2. The span of a network is the maximum hop count to get from one host to any other host on the network. Even if the workgroups divided their LAN network into smaller partitions, the span could only increase to 4 in this particular example. Considering alternative solutions with every router connected to every other router, or if every router was connected to 2 routers, shows the convenience of hierarchical routing. It decreases the complexity of network topology , increases routing efficiency, and causes much less congestion because of fewer routing advertisements. With hierarchical routing, only core routers connected to the backbone are aware of all routes. Routers that lie within a LAN only know about routes in the LAN. Unrecognized destinations are passed to the default route. References FS1037C External links http www.isi.edu nsnam ns doc stable node310.html ... more details

Portal Free software Hierarchical INTegration , or HINT for short, is a computer Benchmark computing benchmark that ranks a computer system as a whole i.e. the entire computer instead of individual components . It measures the full range of performance, mostly based on the amount of work a computer can perform over time. A system with a very fast processor would likely be rated poorly if the Computer bus buses were very poor compared to those of another system that had both an average processor and average buses. For example, in the past, Apple Macintosh Macintosh computers with relatively slow processor speeds 800 MHz used to perform better than x86 based systems with processors running at nearly 2 GHz. HINT is widely known Who date March 2009 for being almost immune to artificial optimization. HINT can be used by many computers ranging from a calculator to a supercomputer.

A storage violation occurs when a task computers task modifies, or attempts to modify, computer storage that it does not own. Types of storage violation Storage violation can, for instance, consist of writing to or freeing storage not owned by the task. A common type of storage violation is known as a stack buffer overflow where a program attempts to alter a memory location beyond its allocated memory. Avoidance of storage violations Storage violations can occur in transaction systems such as CICS in circumstances where it is possible to write to storage not owned by the transaction such violations can be reduced by enabling features such as storage protection and transaction isolation . Detection of storage violations In systems such as CICS, storage violations are sometimes detected by the CICS Kernel computing kernel by the use of signatures , which can be tested to see if they have been overlaid. Some programming languages use software bounds checking to prevent these occurrences. Some program debugging software will also detect violations during testing.
