Pengembangan Media Pembelajaran Virtual dan Interaktif untuk Mensimulasikan Instalasi Jaringan Listrik di SMK 2 Surakarta

Pembelajaran instalasi listrik di SMK sering menjadi masalah karena harus tersedianya peralatan yang harus selalu membeli perangkat nyata namun setelah itu perangkat yang digunakan untuk pembelajaran tidak digunakan kembali dan juga yang penting adalah ternyata cara pembelajaran seperti ini kurang efektif karena biasanya dilakukan secara berkelompok. Pada saat pembelajaran dilakukan secara berkelompok maka ada siswa yang hanya mengandalkan hasil kerja rekan-rekannya dan ada yang tidak memperhatikan terhadap pelajaran yang diberikan akhirnya tidak menerima manfaat dari pembelajaran tersebut. Untuk itu dikembangkan sebuah media interaktif yang ditujukan untuk mensimulasikan rangkaian listrik sederhana sehingga bisa dicoba secara langsung oleh masing-masing siswa secara menarik dan interaktif sehingga setiap siswa akan menjadi senang belajar instalasi listrik dan mendapat manfaat serta bisa menyerap materi yang diinginkan

Observation of Muon Neutrino Disappearance with the MINOS Detectors in the NuMI Neutrino Beam

This Letter reports results from the MINOS experiment based on its initial exposure to neutrinos from the Fermilab NuMI beam. The rates and energy spectra of charged current ν_μ interactions are compared in two detectors located along the beam axis at distances of 1 and 735 km. With 1.27×10^(20) 120 GeV protons incident on the NuMI target, 215 events with energies below 30 GeV are observed at the Far Detector, compared to an expectation of 336±14 events. The data are consistent with ν_μ disappearance via oscillations with Δm_(32)^2|=2.74_(-0.26)^(+0.44)×10^(-3)  eV^2 and sin^2(2θ_(23))>0.87 (68% C.L.)

First observations of separated atmospheric ν_μ and ν̅ _μ events in the MINOS detector

The complete 5.4 kton MINOS far detector has been taking data since the beginning of August 2003 at a depth of 2070 meters water-equivalent in the Soudan mine, Minnesota. This paper presents the first MINOS observations of ν_μ and ν̅ _μ charged-current atmospheric neutrino interactions based on an exposure of 418 days. The ratio of upward- to downward-going events in the data is compared to the Monte Carlo expectation in the absence of neutrino oscillations, giving R^(data)_(up/down/R^(MC)_(up/down) = 0:62^(+0.19)_(0:14)(stat.) ± 0.02(sys.). An extended maximum likelihood analysis of the observed L/E distributions excludes the null hypothesis of no neutrino oscillations at the 98% confidence level. Using the curvature of the observed muons in the 1.3 T MINOS magnetic field ν_μ and ν̅ _μ interactions are separated. The ratio of ν̅ _μ to ν_μ events in the data is compared to the Monte Carlo expectation assuming neutrinos and antineutrinos oscillate in the same manner, giving R^(data)_(ν_μ/ν̅ _μ) / R^(MC)_(ν_μ/ν̅ _μ) = 0.96^(+0:38)_(0.27)(stat.) ± 0.15(sys.), where the errors are the statistical and systematic uncertainties. Although the statistics are limited, this is the first direct observation of atmospheric neutrino interactions separately for ν_μ and ν̅ _μ

Search for the disappearance of muon antineutrinos in the NuMI neutrino beam

We report constraints on antineutrino oscillation parameters that were obtained by using the two MINOS detectors to measure the 7% muon antineutrino component of the NuMI neutrino beam. In the Far Detector, we select 130 events in the charged-current muon antineutrino sample, compared to a prediction of 136.4 ± 11.7(stat)^(+10.2)_(-8.9)(syst) events under the assumption │Δm^2│ = 2.32 X 10^(-3) eV^2, sin^2(2θ) = 1.0

First Direct Observation of Muon Antineutrino Disappearance

This Letter reports the first direct observation of muon antineutrino disappearance. The MINOS experiment has taken data with an accelerator beam optimized for ν̅ _μ production, accumulating an exposure of 1.71×10^(20) protons on target. In the Far Detector, 97 charged current ν̅ _μ events are observed. The no-oscillation hypothesis predicts 156 events and is excluded at 6.3σ. The best fit to oscillation yields |Δm̅ 2|= [3.36=_(-0.40)^(+0.46)(stat)±0.06(syst)]x10^(-3)eV^2,sin^2(2θ̅)=0.86 _(-0.12)^(+0.11)(stat)±0.01(syst). The MINOS ν̅ _μ and ν̅ _μ measurements are consistent at the 2.0% confidence level, assuming identical underlying oscillation parameters

The social shaping of packaged software selection

As organisations increasingly engage in the selection, purchase, and adoption of packaged software products, howthese activities are carried out in practice becomes increasingly relevant for researchers and practitioners. Ourfocus in this paper is to propose a framework for understanding the packaged software selection process. Thefunctionalist literature on this area of study suggests a number of generic recommendations, which are based onrational assumptions about the process and view the decision making that takes place as producing the “besttechnology solution.’” To explore this, we conducted a longitudinal, in-depth study of packaged software selectionin a small organisation. For interpretation of the case, we draw upon the Social Construction of Technology, atheoretical framework arguing that technology is socially constituted and regarding the process of development ascontradictory and uncertain. We offer a number of contributions. First, we further our understanding of packagedsoftware selection with the critique that we offer of the functionalist literature, drawing insights from the emergingcritical/constructivist literature and expanding our domain of interest to encompass the wider environment. Second,we weave this together with our experiences in the field, drawing on social constructivism for theoretical support, todevelop a framework of packaged software selection that shows how various actors shape the process

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

Uncomfortable truths - teamworking under lean in the UK

A recent contribution in this journal – Procter, S. and Radnor, Z. (2014) ‘Teamworking under Lean in UK public services: lean teams and team targets in Her Majesty’s Revenue and Customs (HMRC)’ International Journal of Human Resource Management, 25:21, 2978–2995 – provides an account of teamworking in the UK Civil Service, specifically Her Majesty’s Revenue and Customs (HMRC), focused on the relationship between recently implemented lean work organisation and teams and teamworking. Procter and Radnor claim in this work that it delivers a ‘more nuanced’ analysis of lean in this government department and, it follows, of the lean phenomenon more generally. Our riposte critiques their article on several grounds. It suffers from problems of logic and construction, conceptual confusion and definitional imprecision. Methodological difficulties and inconsistent evidence contribute additionally to analytical weakness. Included in our response are empirical findings on teamworking at HMRC that challenge Procter and Radnor’s evidential basis and further reveal the shortcomings of their interpretation

Critical Reading Across the Engineering Disciplines

Engineering students spend a significant amount of time discovering, evaluating, and reading/interpreting information. This book chapter discusses the existing knowledge around undergraduate engineering student information and critical reading practices and presents a case study that provides a successful pedagogical strategy to address these salient issues in the classroom
