Detailed chronostratigraphic biodatums and lithofacies in combination with correlative seismic horizons recognized two 3rd order depositional sequences designated as Sequence 1 and Sequence 2 in stratigraphic order within Miocene in KD field. The biostratigraphic correlation has brought out that the Sequence 1 in shelf well GS-AD is sandrich and bounded by unconformable sequence boundaries, whereas coeval sequence in slope wells KDA and KDB, bounded by correlative conformities are dominated by clay rich system deposited during highstand sea-levels in earlymiddle Miocene. The clays are planar bedded with glauconite and pyrite nuggets with abundant deepwater benthics in association with shelf derived foraminifera, inferring that these clays were derived into intraslope basins mainly as debris flow/slump process. The Sequence 2 in wells KDA and KDB is represented by multiple sands with mudstone alternations, deposited during lowstand Sea-Levels. Biofacies are mixed with dominantly shelf derived benthics and the tests are commonly broken, abraded and occasionally ferruginised, suggesting reworking into intraslope basins as a result of relative Sea-Level fall during middle and late Miocene. The occurrence of abundant Paleocene to early Miocene dinoflageIlate cyst assemblage are also suggesting reworking process into upper slope by network of active channel system and were redeposited by Gravity-Flow processes into intraslope basins. The present study indicates each intraslope basin acting as an independent petroleum system and matured organic rich Paleogene beds lying at the bottom are contributing hydrocarbons to middle Miocene reservoirs through active growth fault system.Keywords

We associate characteristic equations with a Farey fraction and define fundamental solutions for them. The concept of a tribe is defined for the fraction with the help of these solutions, and some interesting results about these tribes are obtained. We also study the nature of symmetrical elements about a fraction.Keywords

Hamiltonian metrics are introduced on an almost quaternion real manifold. It is proved that every almost quaternion para-compact real manifold admits a Hamiltonian metric. It is established that there is a bijective correspondence between the set of all Hamiltonj.an metrics on an almost quaternion real manifold of dimension 4m with respect to the -canonical almost quaternion structure and the homogeneous space Θ{GL(m,H)}/Θ{Sp(m)}.Keywords

The term, Big Data ‘has been coined to talk to the large bulk of information that can't be forbidden by ancient data-handling techniques. Massive information continues to be a unique thought, and within the following literature we have a tendency to will elaborate it in a very palpable fashion. It commences with the thought of the topic in itself together with its properties and therefore the 2 general approaches of addressing it. The excellent study more goes on to elucidate the applications of huge information altogether various aspects of economy and being. The employment of huge information Analytics once group action it with digital capabilities to secure business growth and its visualisation to form it graspable to the technically indentured business analyzers has been mentioned exhaustive. Aside this, the incorporation of huge information so as to boost population health, for the betterment of finance, medium trade, food trade and for fraud detection and sentiment analysis are represented. The challenges that square measure impeding the expansion of huge information Analytics square measure accounted for exhaustive within the paper. This subject has been white into 2 arenas- one being the sensible challenges faces while the opposite being the theoretical challenges. The hurdles of securing {the information|the info|the information} and democratizing it are detailed amongst many others like inability to find sound information professionals in needed amounts and software system that possess ability to method data at a high speed. Through the article, the authors will decipher the notions in associate degree intelligible manner embodying in text many use-cases and illustrations.
