Heap (data Structure)
In computer science, a heap is a specialized tree-based data structure which is essentially an almost complete tree that satisfies the heap property: in a ''max heap'', for any given node C, if P is a parent node of C, then the ''key'' (the ''value'') of P is greater than or equal to the key of C. In a ''min heap'', the key of P is less than or equal to the key of C. The node at the "top" of the heap (with no parents) is called the ''root'' node. The heap is one maximally efficient implementation of an abstract data type called a priority queue, and in fact, priority queues are often referred to as "heaps", regardless of how they may be implemented. In a heap, the highest (or lowest) priority element is always stored at the root. However, a heap is not a sorted structure; it can be regarded as being partially ordered. A heap is a useful data structure when it is necessary to repeatedly remove the object with the highest (or lowest) priority, or when insertions need to be intersper ...

Treap
In computer science, the treap and the randomized binary search tree are two closely related forms of binary search tree data structures that maintain a dynamic set of ordered keys and allow binary searches among the keys. After any sequence of insertions and deletions of keys, the shape of the tree is a random variable with the same probability distribution as a random binary tree; in particular, with high probability its height is proportional to the logarithm of the number of keys, so that each search, insertion, or deletion operation takes logarithmic time to perform. Description The treap was first described by Raimund Seidel and Cecilia R. Aragon in 1989; its name is a portmanteau of tree and heap. It is a Cartesian tree in which each key is given a (randomly chosen) numeric priority. As with any binary search tree, the inorder traversal order of the nodes is the same as the sorted order of the keys. The structure of the tree is determined by the requirement that it ...

Beap
A beap, or bi-parental heap, is a data structure where a node usually has two parents (unless it is the first or last on a level) and two children (unless it is on the last level). Unlike a heap, a beap allows sublinear search. The beap was introduced by Ian Munro and Hendra Suwanda. A related data structure is the Young tableau. Performance The height of the structure is approximately \sqrt. Also, assuming the last level is full, the number of elements on that level is also \sqrt. In fact, because of these properties all basic operations (insert, remove, find) run in O(\sqrt) time on average. Find operations in the heap can be O(n) in the worst case. Removal and insertion of new elements involves propagation of elements up or down (much like in a heap) in order to restore the beap invariant. An additional perk is that beap provides constant time access to the smallest element and O(\sqrt) time for the maximum element. Actually, a O(\sqrt) find operation can be implemented i ...

Skandha
(Sanskrit) or ( Pāḷi) means "heaps, aggregates, collections, groupings". In Buddhism, it refers to the five aggregates of clinging (), the five material and mental factors that take part in the rise of craving and clinging. They are also explained as the five factors that constitute and explain a sentient being’s person and personality, but this is a later interpretation in response to sarvastivadin essentialism. The five aggregates or heaps of clinging are: # form (or material image, impression) () # sensations (or feelings, received from form) () # perceptions () # mental activity or formations () # consciousness (). In the Theravada tradition, suffering arises when one identifies with or clings to the aggregates. This suffering is extinguished by relinquishing attachments to aggregates. The Mahayana tradition asserts that the nature of all aggregates is intrinsically empty of independent existence. Etymology () is a Sanskrit word that means "multitude, qua ...

Holocaust Education And Avoidance Pod
''Cryptonomicon'' is a 1999 novel by American author Neal Stephenson, set in two different time periods. One group of characters are World War II-era Allied codebreakers and tactical-deception operatives affiliated with the Government Code and Cypher School at Bletchley Park (UK), and disillusioned Axis military and intelligence figures. The second narrative is set in the late 1990s, with characters that are (in part) descendants of those of the earlier time period, who employ cryptologic, telecom, and computer technology to build an underground data haven in the fictional Sultanate of Kinakuta. Their goal is to facilitate anonymous Internet banking using electronic money and (later) digital gold currency, with a long-term objective to distribute Holocaust Education and Avoidance Pod (HEAP) media for instructing genocide-target populations on defensive warfare. Genre and subject matter ''Cryptonomicon'' is closer to the genres of historical fiction and contemporary techn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Explosive, Armor-Piercing
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate either body armour or vehicle armour. From the 1860s to 1950s, a major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly-armoured interiors. From the 1920s onwards, armour-piercing weapons were required for anti-tank warfare. AP rounds smaller than 20 mm are intended for lightly-armoured targets such as body armour, bulletproof glass, and lightly-armoured vehicles. As tank armour improved during World War II, anti-vehicle rounds began to use a smaller but dense penetrating body within a larger shell, firing at very high muzzle velocity. Modern penetrators are long rods of dense material like tungsten or depleted uranium (DU) that further improve the terminal ballistics. History The late 1850s saw the development of the ironclad warship, which carried wrought iron armour of considerable thickness. This ...

Heap (mathematics)
In abstract algebra, a semiheap is an algebraic structure consisting of a non-empty set ''H'' with a ternary operation denoted ,y,z\in H that satisfies a modified associativity property: \forall a,b,c,d,e \in H \ \ \ \ a,b,cd,e] = ,c,b.html"_;"title=",[d,c,b">,[d,c,be=_[a,b,[c,d,e.html" ;"title=",c,b">,[d,c,be.html" ;"title=",c,b.html" ;"title=",[d,c,b">,[d,c,be">,c,b.html" ;"title=",[d,c,b">,[d,c,be= [a,b,[c,d,e">,c,b">,[d,c,be.html" ;"title=",c,b.html" ;"title=",[d,c,b">,[d,c,be">,c,b.html" ;"title=",[d,c,b">,[d,c,be= [a,b,[c,d,e. A biunitary element ''h'' of a semiheap satisfies [''h'',''h'',''k''] = ''k'' = [''k'',''h'',''h''] for every ''k'' in ''H''. A heap is a semiheap in which every element is biunitary. The term ''heap'' is derived from груда, Russian for "heap", "pile", or "stack". Anton Sushkevich used the term in his ''Theory of Generalized Groups'' (1937) which influenced Viktor Wagner, promulgator of semiheaps, heaps, and generalized heaps.C.D. Hollings & M ...

Heap Leaching
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas ''in situ'' mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used in modern large-scale mining operations as it produces the desired concentrates at a lower cost compared to conventional processing methods such as flotation, agitation, and vat leaching. Additionally, dump leaching is an essential part of most copper mining operations and determines the quality grade of the produced material along with other factors Due to the profitability that the dump leaching has on the mining process, i.e. it can contribute substa ...
