A SURVEY ON CHURN ANALYSIS AND PREDICTION IN VIDEO ON DEMAND
Consumer loyalty is a key measure of achievement. Despondent clients will not be staying around the service. When there are unhappy clients once in a while voice their disappointment before leaving. Streaming administration, motion pictures, and television shows are gushing over the internet, not being downloaded, so we should be associated with the internet all through your watch instantly experience. Hence, to help them recognize to disappointed clients†from the get-go in their relationship. Doing as such would permit streaming administration to find a way to enhance client's joy†before it's excessively late. To distinguish the purposes behind clients who are producing from the spilling administration furthermore anticipating what number of clients will get stick around the gushing administration.Â
Iodidotris(triphenylphosphine)copper(I) acetonitrile solvate
The title compound, [CuI(C18H15P)3]·C2H3N, was obtained from the reaction of triphenylphosphine and copper(I) iodide in acetonitrile. The monomeric form of the complex has slightly distorted coordination of Cu by the I atom and three P atoms. The crystal structure is stabilized by C—H⋯π interactions between phenyl H atoms and phenyl rings. In addition, the complex molecules exhibit C—H⋯N hydrogen bonds between phenyl H atoms and acetonitrile N atoms. The crystal used was an inversion twin, with nearly equal component populations of 0.522 (8) and 0.478 (8)
PAC-learning is Undecidable
The problem of attempting to learn the mapping between data and labels is the
crux of any machine learning task. It is, therefore, of interest to the machine
learning community on practical as well as theoretical counts to consider the
existence of a test or criterion for deciding the feasibility of attempting to
learn. We investigate the existence of such a criterion in the setting of
PAC-learning, basing the feasibility solely on whether the mapping to be learnt
lends itself to approximation by a given class of hypothesis functions. We show
that no such criterion exists, exposing a fundamental limitation in the
decidability of learning. In other words, we prove that testing for
PAC-learnability is undecidable in the Turing sense. We also briefly discuss
some of the probable implications of this result to the current practice of
machine learning
Chlorido(1-cyclopentylidene-4-ethylthiosemicarbazidato-κ2 N 1,S)diphenyltin(IV)
The Sn atom in the title compound, [Sn(C6H5)2(C8H14N3S)Cl], is pentacoordinated with a trigonal-bipyramidal coordination geometry. The 1-cyclopentylidene-4-ethylthiosemicarbazidate (cpetsc) ligand coordinates through the S atom and the N atom bonds to the cyclopentyl group, forming a five-membered ring with the Sn center. The chloride ligand and the coordinated N atom are in axial positions. In the crystal structure, intermolecular N—H⋯Cl hydrogen bonds form chains along [101]
Effectiveness of static bicycle on improving paediatric endurance in spastic diplegic cerebral palsy children
INTRODUCTION : Spastic diplegia ‘s particular type of brain damage inhibits the proper development of upper motor neuron function,impacting the motor cortex,the basal ganglia and the corticospinal tract.This abnormally high muscle tone that results creates life long difficulty with all voluntary and passive movement in the legs and in general creates stress over time.Constant spasticity ultimately produces pain,muscle/joint break down.
OBJECTIVE : It is an experimental study design to determine the
effectiveness of static bicycle on improving pediatric endurance n spastic diplegic
cerebral palsy children.
DESIGN: The study was Pre-test and post-test experimental group design.
PARTICIPANTS : A sample of 40 spastic diplegic cerebral palsy children were divided in to 2 groups :
Group A :Experimental group :Treated with static bicycle
Group B : Control group treated with traditional stretching and
mat activities.
OUTCOME MEASURES : Pediatric endurance was measured using 600-yard walk run test and 30 sec walk test.
RESULTS : Statistically group A was significant when compared to group B which received
stationary bicycle.
CONCLUSION : The study concludes that stationary bicycling in beneficial in improving
paediatric endurance in patients with spastic diplegic cerebral palsy.Thus, this study accepts
the alternate hypothesis
Chloridodiphenyl{[1-(1,3-thiazol-2-yl-κN)ethylidene]-4-phenylthiosemicarbazidato-κ2 N 1,S}tin(IV) methanol monosolvate
The title compound, [Sn(C6H5)2(C12H11N4S2)Cl]·CH4O, is formed during the reaction between 2-acetylthiazole 4-phenylthiosemicarbazone (Hacthptsc) and diphenyltin(IV) dichloride in methanol. In the crystal structure, the Sn atom exhibits an octahedral geometry with the [N2S] anionic tridentate thiosemicarbazone ligand having chloride trans to the central N and the two phenyl groups trans to each other. The Sn—Cl distance is 2.5929 (6), Sn—S is 2.4896 (6) and Sn—N to the central N is 2.3220 (16) Å. The MeOH molecules link the Sn complexes into one-dimensional chains via N—H⋯O and O—H⋯Cl hydrogen bonds
Relativistic spin precession in the binary PSR J11416545
PSR J11416545 is a precessing binary pulsar that has the rare potential to
reveal the two-dimensional structure of a non-recycled pulsar emission cone. It
has undergone of relativistic spin precession in the
years since its discovery. In this paper, we present a detailed Bayesian
analysis of the precessional evolution of the width of the total intensity
profile, to understand the changes to the line-of-sight impact angle ()
of the pulsar using four different physically motivated prior distribution
models. Although we cannot statistically differentiate between the models with
confidence, the temporal evolution of the linear and circular polarisations
strongly argue that our line-of-sight crossed the magnetic pole around MJD
54000 and that only two models remain viable. For both these models, it appears
likely that the pulsar will precess out of our line-of-sight in the next
years, assuming a simple beam geometry. Marginalising over suggests
that the pulsar is a near-orthogonal rotator and provides the first
polarization-independent estimate of the scale factor () that
relates the pulsar beam opening angle () to its rotational period ()
as : we find it to be at 1.4
GHz with 99\% confidence. If all pulsars emit from opposite poles of a dipolar
magnetic field with comparable brightness, we might expect to see evidence of
an interpulse arising in PSR J11416545, unless the emission is patchy.Comment: Accepted for publication in Astrophysical Journal Letter
A report on rare occurrence of a mushroom coral, Cycloseris cyclolites (Lamarck, 1801) in Gulf of Mannar, India
333-334The frequent heavy–scale climatic oscillations and the recent local disturbances on the reefs worldwide were a menace for biodiversity sustenance. The major concern is that many species of Scleractinian corals could have been lost while being unaware of their existence. The recent survey yielded Cycloseris cyclolites after 29 years in the reef areas of the Gulf of Mannar Marine National Park
Oral Health Promotion: Evidences and Strategies
Oral health promotion is for upliftment of oral health of community rather than an individual and has long‐term impact. Since Ottawa Charter for health promotion is implemented, significant advancements have happened in oral health promotion. Under comprehensive health programs, India has been running oral health promotion programs, and these evidences are shared here. Such examples are apt learning and execution to any part of world having similarities. The chapter put forward the strategic view points to consider further oral health promotion aspects and based on the needs. The authors have gathered various examples from national programs implemented in India. The authors discuss how these programs are linked to the Oral health promotion concept. For example, National tobacco control program which currently running across many states in India, how the banning on tobacco products near school premises helped to reduce the incidence is discussed. The worldwide literature and evidences of oral health promotion strategies are explained. The evidences and strategies mentioned can be significant for another region of world. Unless published, many programs remain hidden and are loss of valuable evidences to oral health science
