    Kebutuhan akan 4G LTE sangat pesat di banding dengan teknologi sebelumnya 4G LTE sangat mumpuni dalam segala hal, oleh karena itu Telkomsel sangat terpacu untuk menjaga akan kualitas dari performasi 4G LTE Telkomsel pun melakukan Global Frequency Retune (GFR). Oleh karena itu, untuk mengetahui performansi teknologi LTE Telkomsel dilakukanlah penelitian terhadap performansi bandwith 10MHz dan 15MHz. Untuk wilayah Bukit & Jakabaring didapatkan hasil yaitu RSRP sebesar 100% untuk ≥(-100 ) dBm, SINR pada wilayah Bukit 94.34% >0dBm, dan wilayah Jakabaring 70.27% dan troughput pada wilayah Bukit 72.57% ≥ 2 Mbps dan di Jakabaring 48.28%

    The purpose of this study was to explore the facets of the hidden curriculum in a Junior Science College from the perspective of students labelled as gifted. This college is set up specifically for gifted and high academic achiever students. A qualitative approach was chosen to gather the data from former students and current teachers of this college. The data was collected from three focus group interviews with 16 former students, individual interviews with four students and 6 teachers, observations of school activities and document reviews. The data was analysed manually, codes and categories were identified and a rich description based on the categories was written to answer the research question. The results showed that the hidden curriculum is the result of the practices, procedures, rules, relationships, structures and physical characteristics of the Special Education Program (SEP). Eight themes were identified which resulted in the learning of intrapersonal and interpersonal skills. The study concluded that the hidden curriculum facilitated the transmission of social norms while the learning improved positive interpersonal and intrapersonal skills in the students, in spite of the restrictive nature of the special education program. According to the results, it can be concluded that flexibility and creativity in instruction promotes positive traits in students and teachers

    Nucleon-Nucleon Correlations and Two-Nucleon Currents in Exclusive (e,eNNe,e'NN) Reactions

    The contributions of short-range nucleon-nucleon (NN) correlations, various meson exchange current (MEC) terms and the influence of Δ\Delta isobar excitations (isobaric currents, IC) on exclusive two-nucleon knockout reactions induced by electron scattering are investigated. The nuclear structure functions are evaluated for nuclear matter. Realistic NN interactions derived in the framework of One-Boson-Exchange model are employed to evaluate the effects of correlations and MEC in a consistent way. The correlations correlations are determined by solving the Bethe-Goldstone equation. This yields significant contributions to the structure functions W_L and W_T of the (e,e'pn) and (e,e'pp) reactions. These contributions compete with MEC corrections originating from the π\pi and ρ\rho exchange terms of the same interaction. Special attention is paid to the so-called 'super parallel' kinematics at momentum transfers which can be measured e.g. at MAMI in Mainz.Comment: 14 pages, 8 figures include

    Correlation effects in single-particle overlap functions and one-nucleon removal reactions

    Get PDF
    Single-particle overlap functions and spectroscopic factors are calculated on the basis of the one-body density matrices (ODM) obtained for the nucleus 16O^{16}O employing different approaches to account for the effects of correlations. The calculations use the relationship between the overlap functions related to bound states of the (A-1)-particle system and the ODM for the ground state of the A-particle system. The resulting bound-state overlap functions are compared and tested in the description of the experimental data from (p,d) reactions for which the shape of the overlap function is important.Comment: 11 pages, 4 figures include

    A Self-Consistent Solution to the Nuclear Many-Body Problem at Finite Temperature

    Full text link
    The properties of symmetric nuclear matter are investigated within the Green's functions approach. We have implemented an iterative procedure allowing for a self-consistent evaluation of the single-particle and two-particle propagators. The in-medium scattering equation is solved for a realistic (non-separable) nucleon-nucleon interaction including both particle-particle and hole-hole propagation. The corresponding two-particle propagator is constructed explicitely from the single-particle spectral functions. Results are obtained for finite temperatures and an extrapolation to T=0 is presented.Comment: 11 pages 5 figure

    Convex-Cyclic Weighted Translations On Locally Compact Groups

    Full text link
    A bounded linear operator TT on a Banach space XX is called a convex-cyclic operator if there exists a vector xXx \in X such that the convex hull of Orb(T,x)Orb(T, x) is dense in XX. In this paper, for given an aperiodic element gg in a locally compact group GG, we give some sufficient conditions for a weighted translation operator Tg,w:fwfδgT_{g,w}: f \mapsto w\cdot f*\delta_g on Lp(G)\mathfrak{L}^{p}(G) to be convex-cyclic. A necessary condition is also studied. At the end, to explain the obtained results, some examples are given

    A qualitative study on personal information management (PIM) in clinical and basic sciences faculty members of a medical university in Iran

    Background: Personal Information Management (PIM) refers to the tools and activities to save and retrieve personal information for future uses. This study examined the PIM activities of faculty members of Iran University of Medical Sciences (IUMS) regarding their preferred PIM tools and four aspects of acquiring, organizing, storing and retrieving personal information. Methods: The qualitative design was based on phenomenology approach and we carried out 37 interviews with clinical and basic sciences faculty members of IUMS in 2014. The participants were selected using a random sampling method. All interviews were recorded by a digital voice recorder, and then transcribed, codified and finally analyzed using NVivo 8 software. Results: The use of PIM electronic tools (e-tools) was below expectation among the studied sample and just 37 had reasonable knowledge of PIM e-tools such as, external hard drivers, flash memories etc. However, all participants used both paper and electronic devices to store and access information. Internal mass memories (in Laptops) and flash memories were the most used e-tools to save information. Most participants used "subject" (41.00) and "file name" (33.7 ) to save, organize and retrieve their stored information. Most users preferred paper-based rather than electronic tools to keep their personal information. Conclusion: Faculty members had little knowledge about PIM techniques and tools. Those who organized personal information could easier retrieve the stored information for future uses. Enhancing familiarity with PIM tools and training courses of PIM tools and techniques are suggested
