Studies on properties and estimation problems for modified extension of exponential distribution

The present paper considers modified extension of the exponential distribution with three parameters. We study the main properties of this new distribution, with special emphasis on its median, mode and moments function and some characteristics related to reliability studies. For Modified- extension exponential distribution (MEXED) we have obtained the Bayes Estimators of scale and shape parameters using Lindley's approximation (L-approximation) under squared error loss function. But, through this approximation technique it is not possible to compute the interval estimates of the parameters. Therefore, we also propose Gibbs sampling method to generate sample from the posterior distribution. On the basis of generated posterior sample we computed the Bayes estimates of the unknown parameters and constructed 95 % highest posterior density credible intervals. A Monte Carlo simulation study is carried out to compare the performance of Bayes estimators with the corresponding classical estimators in terms of their simulated risk. A real data set has been considered for illustrative purpose of the study.Comment: 22,

The purpose of the research is to analyse the effect of the USAge of learning strategies preview, question, read, reflect, ricete, review on fifth grade child story reading students' skills in 15th state elementary school in south Pontianak. The method that has been used was experiment method with forms of Pre-experimental design in the stake one group pretest posttest design. Research population of the entire fifth grad consists of 24 students in 15thstate elementary school in south Pontianak. The research sample was a class sample that is class fifth. Based on the result of data analysis, the mean of pre test was 63,26 and the mean of post test was 69,56. The hypothesis test result using t-test (Polled Variance) with dk 22 on 5 % significant level as known as table t = 1,717 obtained count (table t = 1,717). Then Ha accepted and Ho rejected. It could be conclude that there is an learning strategies preview, question, read, reflect, ricete, review on fifth grade child story reading students' skills in 15th state elementary school in south Pontianak. The result of the calculation on the effect size is 1,02 (high criteria). It means that the USAge of learning strategies preview, question, read, reflect, ricete, review gave high influence (effect) on fifth grade child story reading students' skills in 15th state elementary school in south Pontianak

The Higgs Potential in the Type II Seesaw Model

We perform in the type II seesaw setting, a detailed study of the dynamical features of the corresponding general renormalizable doublet/triplet Higgs potential that depends on five dimensionless couplings and two mass parameters after spontaneous symmetry breaking, and highlight the implications for the Higgs phenomenology. In particular, we determine i) the complete set of tree-level unitarity constraints on the couplings of the potential and ii) the exact tree-level {\sl all directions} boundedness from below constraints on these couplings. When combined, these constraints delineate precisely the theoretically allowed parameter space domain within our perturbative approximation. Among the seven physical Higgs states of this model, the mass of the lighter (heavier) CP-even state h0 (H0) will always satisfy a theoretical upper (lower) bound that is reached for a critical value mu_c of mu (the mass parameter controlling triple couplings among the doublet/triplet Higgses). Saturating the unitarity bounds we find m_h0 < {\cal O}(0.7 - 1 TeV), while the upper bound for the remaining Higgses lies in the several tens of TeV. However, the actual masses can be much lighter. We identify two regimes corresponding to mu > mu_c and mu < mu_c. In the first regime the Higgs sector is typically very heavy and only h0 that becomes SM-like could be accessible to the LHC. In contrast, in the second regime, somewhat overlooked in the literature, most of the Higgs sector is light. In particular the heaviest state H0 becomes SM-like, the lighter states being the CP-odd Higgs, the (doubly) charged Higgses and a decoupled h0, possibly leading to a distinctive phenomenology at the colliders.Comment: 55 pages, 9 figures, no major changes, references added, a comment added to sec 3.1, typos correcte

Behaviors of Some Soybean Cultivars (Glycine max L.) Yield to Planting Dates and Different Phosphorus Fertilizer Rates

Soybean production components such as planting date, cultivars and phosphorus fertilizer rates affected soybean yield. Two field experiments conducted in extensive field at El-Gahrbia district, Egypt during 2015 and 2016 seasons. The goal of this research was aimed to investigate the influence of sowing date at 1th May, 15th May and 31th May and three phosphorus fertilization rates, i.e. 0, 37.2 and 74.4 kg P2O5/ha on the performance of three soybean (Glycine max (L.) Merrl) cultivars i.e. Crawford, Giza 22 and Giza 111 on growth, yield and seed quality. The tallest plants, the thick stem, highest branches number/plant, pods number/plant, seed number/pod, weight of 1000 seed and seed yield/ha were recorded from sown early on first May in the both seasons. The tallest plants, the thick stems and highest number of branches/plant were recorded from sown Crawford cultivar. Whereas maximum number of pods/plant and number of seed/pod were found from sown Giza 111 cultivar in the both seasons. Increasing phosphorous fertilizer rates significantly increased all studied cultivars of seed yield and yield components. Tallest plant, the thick stem, the highest branches number/plant, pods number/plant, seed number/pod, weight of1000 seed and seed yield/ha were produced from phosphorous fertilizer at a rate of 74.4 kg P2O5/ha in the first and second seasons, respectively

Study of Wave and Tidal Currents at the Coastal Waters of Pasir Jambak Padang City West Sumatra Province

This research was conducted in July 2016 at the coastal waters of Pasir Jambak Padang City West Sumatera Province with intention to determine the characteristics of wave and tidal currents. The stasion observation way is determined by using a purposive method. Research location divided into three stations, where each station consists of three sampling points, the distance between stations of approximately 100 m. Performed during 15 days of observation. Every station was placed parallel to the coastline, a distance less than 100 meters from the beach toward the Sea. High wave at high tide ranges from 0.21 - 0.33 m and 0.23 - 0.35 m at low tide. Wave period ranges from 1.54 to 2.23 seconds at high tide and 1.43 to 1.97 seconds at low tide. Wavelength ranges between 3.86 to 7.8 m at high tide and 3.35 to 6.08 m at low tide. Current velocity ranges between 0.37 to 0.64 m/sec at high tide and 0.36 to 0.51 m/sec at low tide. At the high tide the flow towards the southeast and at the low tide towards to the southwest
