The purpose of this work is to calculate Surge and Swab pressure in oil wells with eccentricity between drill string and wellbore or casing string. Analysis of this phenomenon, in which the fluid is confined between two eccentric cylinders, are made. The conformal mapping is used to lead the eccentric domain into the concentric domain, since the usual models correspond to concentric geometries. The results of this study, using the proposed methodology, are presented and discussed.

Several thousand core-collapse supernovae (CCSNe) of different flavors have been discovered so far. However, identifying their progenitors has remained an outstanding open question in astrophysics. Studies of SN host galaxies have proven to be powerful in providing constraints on the progenitor populations. In this paper, we present all CCSNe detected between 2009 and 2017 by the Palomar Transient Factory. This sample includes 888 SNe of 12 distinct classes out to redshift z ≈ 1. We present the photometric properties of their host galaxies from the far-ultraviolet to the mid-infrared and model the host-galaxy spectral energy distributions to derive physical properties. The galaxy mass functions of Type Ic, Ib, IIb, II, and IIn SNe ranges from 105 to 1011.5 M☉, probing the entire mass range of star-forming galaxies down to the least-massive star-forming galaxies known. Moreover, the galaxy mass distributions are consistent with models of star-formation-weighted mass functions. Regular CCSNe are hence direct tracers of star formation. Small but notable differences exist between some of the SN classes. Type Ib/c SNe prefer galaxies with slightly higher masses (i.e., higher metallicities) and star-formation rates than Type IIb and II SNe. These differences are less pronounced than previously thought. H-poor SLSNe and SNe Ic-BL are scarce in galaxies above 1010 M☉. Their progenitors require environments with metallicities of Copyright © 2020, The Authors. All rights reserved.

Maintenance shares significant operating costs in an organisation. It is considered as a main pillar of the organisational performance. Lean thinking can be incorporated into maintenance activities through applying its principles and practices. Lean maintenance is a prerequisite for lean manufacturing systems. The exhaustive literature review has been conducted to collect the up-to-date maintenance strategies and activities, lean principles and practices in the lean maintenance process. The scope of this paper includes eight types of waste (non-value added maintenance activities), maintenance value stream mapping and a scheme of lean maintenance practices. The output of this paper is a proposed roadmap to apply lean thinking in a maintenance process. © 2015 The Authors

Internet penetration in developing countries depend on a variety of factors, including the Gross Domestic Product (GDP), the density of telephone connections, and the density of personal computer users. Internet kiosks have been deployed in 21 rural ditrict areas of Garut Regency to facilitate internet access for local/district government as well as for the community who have no access to internet. Each district was equiped with 10 PCs, a printer, a scanner, and an internet connection either using DSL or cellular access technology. The program was government sponsored through the Ministry of Communications and Information of the Republic of Indonesia. This program was also designed to provide education and training for the district internet kiosks operator as well as for the staffs of information technology at Garut Regency, on understanding, efficient use, management, maintenance, as well as the ethical/professional use of information to upgrade their skills. This study was then conducted to evaluate factors affecting internet penetration in rural areas of Garut Regency, West Java of Indonesia. © 2015 IEEE.

A search for heavy resonances decaying into a W or Z boson and a Higgs boson produced in proton−proton collisions at the Large Hadron Collider at s=13 TeV is presented. The analysis utilizes the dominant W→qq¯′ or Z→qq¯ and H→bb¯ decays with substructure techniques applied to large-radius jets. A sample corresponding to an integrated luminosity of 139 fb−1 collected with the ATLAS detector is analyzed and no significant excess of data is observed over the background prediction. The results are interpreted in the context of the heavy vector triplet model with spin-1 W′ and Z′ bosons. Upper limits on the cross section are set for resonances with mass between 1.5 and 5.0 TeV, ranging from 6.8 to 0.53 fb for W′→WH and from 8.7 to 0.53 fb for Z′→ZH at the 95% confidence level.

This paper describes a search for beyond the Standard Model decays of the Higgs boson into a pair of new spin-0 particles subsequently decaying into b-quark pairs, H→aa→(bb¯)(bb¯), using proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider at center-of-mass energy s=13 TeV. This search focuses on the range 15 GeV≤ma≤30 GeV, where the decay products are collimated; it is complementary to a previous search in the same final state targeting the range 20 GeV≤ma≤60 GeV, where the decay products are well separated. A novel strategy for the identification of the a→bb¯ decays is deployed to enhance the efficiency for topologies with small separation angles. The search is performed with 36 fb−1 of integrated luminosity collected in 2015 and 2016 and sets upper limits on the production cross section of H→aa→(bb¯)(bb¯), where the Higgs boson is produced in association with a Z boson.

The aims of this research were to study: 1) correlation between creative thinking skill with vocational maturity; 2) correlation between competency achievement with vocational maturity; and 3) correlation between creative thinking skill and competency achievement with vocational maturity simultaneously. In this research, creative thinking skill (X1) and competency achievement (X2) were independent variables and dependent variable was vocational maturity (Y). The population of this research was entire of vocational high school students grade XI Computer and Network engineering. The total number of population was 337 students. The sampling technique used was proportional random sampling, so the total number of sample was 182 students. This research used quantitative approach and the kind of research was descriptive correlational. The analysis data used descriptive analysis, classic assumption test, and hypothesis test were consist of correlation product moment and multiple regression. Correlation product moment was used to determine relationship between dependent variable with each independent variable partially, whereas multiple regression was used to determine correlation between independent variables with dependent variables simultaneously. The results showed that there was a positive and significant correlation between creative thinking skill with vocational maturity. It was observed from the magnitude of Coefficient Correlation (R) = 0.606. And then, there was a positive and significant correlation between competency achievement with vocational maturity. It was observed from the magnitude of Coefficient Correlation (R) = 0.733. There was positive and significant correlation simultaneously between creative thinking skill and competency achievement with vocational maturity. It was observed from the magnitude of R = 0.769 and R square = 0.591. Based on the result of this research could be concluded that ha (hypothesis alternative) was accepted and ho (hypothesis 0)

Experimental investigation on liquid film asymmetry in air-water horizontal annular flow

引用

AIP Conference Proceedings 2016年第1期1737卷

作者： Andriyanto Setyawan Deendarlianto Indarto Fredrick Neo 1Graduate Program Department of Mechanical and Industrial Engineering Faculty of Engineering Gadjah Mada University Jalan Grafika No. 2 Yogyakarta 55281 Indonesia 3Department of Refrigeration and Air Conditioning Engineering Politeknik Negeri Bandung Bandung 40123 Indonesia 2Department of Mechanical and Industrial Engineering Faculty of Engineering Gadjah Mada University Jalan Grafika No. 2 Yogyakarta 55281 Indonesia

The asymmetry of circumferential liquid film thickness distribution in an air-water horizontal annular flow has been experimentally investigated using superficial gas and liquid velocity of 10 – 40 m/s and 0.025 to 0.4 m/s, respectively. In general, the film at the bottom of the pipe will be thicker than that of the side and the top. The asymmetry parameter could be expressed in the ratio of average film thickness to the bottom film thickness or the ratio of the top-to-bottom film thickness. Measurement using compact multiple probe instrument shows that the circumferential film thickness distribution is strongly affected by superficial gas velocity. The higher gas velocity results in the more uniform liquid film circumferential distribution. In comparison to the existing correlations, the asymmetry parameter resulted from the experiment shows a good agreement. It is also shown from the experiment that a less symmetry of film thickness distribution is resulted when the gravity force is dominant. A more symmetry distribution is resulted when the inertial force takes control.
