Hall–Janko Group
In the area of modern algebra known as group theory, the Janko group ''J2'' or the Hall-Janko group ''HJ'' is a sporadic simple group of Order (group theory), order : 604,800 = 2733527 : ≈ 6. History and properties ''J2'' is one of the 26 Sporadic groups and is also called Hall–Janko–Wales group. In 1969 Zvonimir Janko predicted J2 as one of two new simple groups having 21+4:A5 as a centralizer of an involution (the other is the Janko group J3). It was constructed by as a rank 3 permutation group on 100 points. Both the Schur multiplier and the outer automorphism group have order 2. As a permutation group on 100 points J2 has involution (mathematics)#group theory, involutions moving all 100 points and involutions moving just 80 points. The former involutions are products of 25 double transportions, an odd number, and hence lift to 4-elements in the Covering_groups_of_the_alternating_and_symmetric_groups, double cover 2.A100. The double cover 2.J2 occu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamilton–Jacobi Equation
In physics, the Hamilton–Jacobi equation, named after William Rowan Hamilton and Carl Gustav Jacob Jacobi, is an alternative formulation of classical mechanics, equivalent to other formulations such as Newton's laws of motion, Lagrangian mechanics and Hamiltonian mechanics. The Hamilton–Jacobi equation is a formulation of mechanics in which the motion of a particle can be represented as a wave. In this sense, it fulfilled a long-held goal of theoretical physics (dating at least to Johann Bernoulli in the eighteenth century) of finding an analogy between the propagation of light and the motion of a particle. The wave equation followed by mechanical systems is similar to, but not identical with, the Schrödinger equation, as described below; for this reason, the Hamilton–Jacobi equation is considered the "closest approach" of classical mechanics to quantum mechanics. (particularly the discussion beginning in the last paragraph of page 491) The qualitative form of this conne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptoperiod
A cryptoperiod is the time span during which a specific cryptographic key is authorized for use. Common government guidelines range from 1 to 3 years for asymmetric cryptography, and 1 day to 7 days for symmetric cipher traffic keys. Factors to consider include the strength of the underlying encryption algorithm, key length, the likelihood of compromise through a security breach and the availability of mechanisms of revoking keys. In traditional cryptographic practice, keys were changed at regular intervals, typically at the same time each day. The code word for a key change, in NSA parlance, is HJ or Hotel Juliet in the NATO phonetic alphabet. When cryptographic devices began to be used in large scale, those who had to update the key had to set a specific time to synchronize the re-key. This was accomplished at the hour (H) the Julian (J) Date changed, among crypto-accountants, managers and users the jargon "HJ" became the accepted term meaning it was time to change the crypto- ...

List Of Latin-script Digraphs
This is a list of digraphs used in various Latin alphabets. In the list, letters with diacritics are arranged in alphabetical order according to their base, e.g. is alphabetised with , not at the end of the alphabet, as it would be in Danish, Norwegian and Swedish. Substantially-modified letters, such as (a variant of ) and (based on ), are placed at the end. Capitalisation only involves the first letter ( becomes ) unless otherwise stated ( becomes in Dutch, and digraphs marking eclipsis in Irish, are capitalised on the second letter, i.e. becomes ). Apostrophe Source: (capital ) is used in Bari for . (capital ) is used in Bari for . is used in the Wu MiniDict Romanisation for dark or ''yin'' tone .

Hj-reduction
The phonological history of English includes various changes in the phonology of consonant clusters. H-cluster reductions The H-cluster reductions are various consonant reductions that have occurred in the history of English, involving consonant clusters beginning with that have lost the (or become reduced to ) in some or all dialects. Reductions of /hw/ The cluster (spelled ⟨wh⟩ since Middle English) has been subject to two kinds of reduction: * Reduction to before rounded vowels (due to being perceived as a with the labialization characteristic of that environment). This occurred with the word ''how'' in the Old English period, and with ''who'', ''whom'' and ''whose'' in Middle English (the latter words having had an unrounded vowel in Old English). * Reduction to , a development that has affected the speech of the great majority of English speakers, causing them to pronounce ⟨wh-⟩ the same as ⟨w-⟩ (sometimes called the ''wine–whine merger'' or '' g ...

Hajji
Hajji (; sometimes spelled Hajjeh, Hadji, Haji, Alhaji, Al-Hadj, Al-Haj or El-Hajj) is an honorific title which is given to a Muslim who has successfully completed the Hajj to Mecca. Etymology ''Hajji'' is derived from the Arabic ' (), which is the active participle of the verb ' ('to make the pilgrimage'; ). The alternative form ' is derived from the name of the Hajj with the adjectival suffix -''ī'' (), and this was the form adopted by non-Arabic languages. Use ''Hajji'' and its variant spellings are used as honorific titles for Muslims who have successfully completed the Hajj to Mecca. In Arab countries, ' and ' (pronunciation varies by varieties of Arabic, Arabic dialect) is a commonly used manner of addressing any older person respectfully if they have performed the pilgrimage. It is often used to refer to an elder, since it can take years to accumulate the wealth to fund the travel (particularly before commercial air travel), and in many Muslim societies to a respected ...

Handjob
A handjob (also spelled hand job) is a manual sex act involving a person stimulating the penis or scrotum of another by using the hand. This is done to induce an erection for sexual pleasure, sexual arousal and may result in orgasm and ejaculation. A handjob can be performed as either foreplay or as non-penetrative sex. It is analogous to fingering (manual stimulation of the vulva or vagina). Someone may give a handjob so as not to engage in penetrative sexual activity. Besides avoiding the risks associated with sexual penetration, such as sexually transmitted infections (STIs) or pregnancy from penile-vaginal sex, some people engage in non-penetrative sex to preserve virginity. Practice General The main aspect of a handjob is manual stimulation of the penis by stroking with the hand, rubbing with the fingers, or some combination. One common technique is to move the hand (or both hands) up and down on the shaft, glans, and frenulum. The movements and speed of the action ...

Hitler-Jugend
The Hitler Youth ( , often abbreviated as HJ, ) was the youth wing of the German Nazi Party. Its origins date back to 1922 and it received the name ("Hitler Youth, League of German Worker Youth") in July 1926. From 1936 until 1945, it was the sole official boys' youth organisation in Germany (although the League of German Girls was a wing of it) and it was partially a paramilitary organisation. It was composed of the Hitler Youth proper for male youths aged 14 to 18, and the German Youngsters in the Hitler Youth ( or "DJ", also "DJV") for younger boys aged 10 to 14. With the surrender of Nazi Germany in 1945, the organisation '' de facto'' ceased to exist. On 10 October 1945, the Hitler Youth and its subordinate units were outlawed by the Allied Control Council along with other Nazi Party organisations. Under Section 86 of the Criminal Code of the Federal Republic of Germany, the Hitler Youth is an "unconstitutional organisation" and the distribution or public use of its s ...

Holden HJ
The Holden HJ is a series of automobiles which were produced by Holden in Australia from 1974 to 1976. The HJ series was released on 4 October 1974 and was an improved and facelifted version of the superseded Holden HQ series which had been in production since 1971. Model range All HJ models, aside from the One Tonner, were easily identified from the HQ by having a squared-off frontal treatment with wraparound indicator lights. The rear of the sedan models featured a new bumper and wraparound triangular taillights, while all other body styles kept the previous HQ's rear styling. Sedan and wagon also had revised rear quarter panels. The mainstream passenger car range consisted of 4-door sedan and 5-door wagon models in three trim levels. * Belmont sedan * Belmont wagon * Kingswood sedan * Kingswood wagon * Premier sedan * Premier wagon The Premier was distinguished from the cheaper models by a four headlight frontal treatment. Wagons rode on a wheelbase which was three inch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Jupiter
Hot Jupiters (sometimes called hot Saturns) are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter (i.e. Jupiter analogue, Jupiter analogues) but that have very short orbital periods (). The close proximity to their stars and high surface-atmosphere temperatures resulted in their informal name "hot Jupiters". Hot Jupiters are the easiest extrasolar planets to detect via the radial velocity, radial-velocity method, because the oscillations they induce in their parent stars' motion are relatively large and rapid compared to those of other known types of planets. One of the best-known hot Jupiters is . Discovered in 1995, it was the first extrasolar planet found orbiting a Sun-like star. has an orbital period of about four days. General characteristics Though there is diversity among hot Jupiters, they do share some common properties. * Their defining characteristics are their large masses and short orbital periods, spanning 0.36–11.8 ...
