Aplikasi Pengelolaan Data Praktikum Laboratorium Komputer STMIK Widya Cipta Dharma Berbasis Intranet
UPT. Laboratorium komputer STMIK Widya Cipta Dharma merupakan sebuah unit kerja yang memberikan pelayanan akademik. Laboratorium Komputer mempunyai fungsi sebagai tempat proses pembelajaran. Dalam kegiatan praktikum pada laboratorium komputer mahasiswa menggunakan komputer tetap dalam praktikum mata kuliah tersebut karena data-data praktikum hanya ada pada komputer tersebut tanpa mempunyai penyimpanan data yang baik. Apabila mahasiswa maupun dosen ingin meminta data-data tersebut meraka harus menghubungi admin laboratorium tersebut mendapatkan data-data praktikum tersebut lalu membuka komputer mahasiswa tersebut untuk disalin data-datanya. Hal ini tidak efisien dalam melakukan pertukaran data ditambah komputer digunakan oleh banyak mahasiswa membuat data -data praktikum menumpuk dan dapat tercampur dengan data mahasiswa lain.
Penelitian ini dibuat untuk mengatasi berbagai kendala yang dihadapi oleh Laboratorium Komputer STMIK WICIDA. Dalam membangun aplikasi ini menggunakan metode pengembangan sistem waterfall, metode pengujian blackbox dan pengujian beta, database MYSQL dan menggunakan bahasa pemrograman PHP (PHP Hypertext Preprocessor), dreamweaver sebagai webeditor, apache sebagai webserver local, flowchart, Data Flow Diagram dan Entity Relationship Diagram sebagai alat bantu perancangan sistem.
Dengan adanya aplikasi pengelolaan data praktikum berbasis intranet ini diharapkan dapat membantu laboratorium komputer STMIK WICIDA dan memberikan kemudahan dalam pengelolaan data praktikum

Combining social network analysis and the NATO Approach Space to define agility. Topic 2: networks and networking
This paper takes the NATO SAS-050 Approach Space, a widely accepted model of command and control, and gives each of its primary axes a quantitative measure using social network analysis. This means that the actual point in the approach space adopted by real-life command and control organizations can be plotted along with the way in which that point varies over time and function. Part 1 of the paper presents the rationale behind this innovation and how it was subject to verification using theoretical data. Part 2 shows how the enhanced approach space was put to use in the context of a large scale military command post exercise. Agility is represented by the number of distinct areas in the approach space that the organization was able to occupy and there was a marked disparity between where the organization thought it should be and where it actually was, furthermore, agility varied across function. The humans in this particular scenario bestowed upon the organization the levels of agility that were observed, thus the findings are properly considered from a socio-technical perspective
Slow flows of an relativistic perfect fluid in a static gravitational field
Relativistic hydrodynamics of an isentropic fluid in a gravitational field is
considered as the particular example from the family of Lagrangian
hydrodynamic-type systems which possess an infinite set of integrals of motion
due to the symmetry of Lagrangian with respect to relabeling of fluid particle
labels. Flows with fixed topology of the vorticity are investigated in
quasi-static regime, when deviations of the space-time metric and the density
of fluid from the corresponding equilibrium configuration are negligibly small.
On the base of the variational principle for frozen-in vortex lines dynamics,
the equation of motion for a thin relativistic vortex filament is derived in
the local induction approximation.Comment: 4 pages, revtex, no figur
Velocity profiles in shear-banding wormlike micelles
Using Dynamic Light Scattering in heterodyne mode, we measure velocity
profiles in a much studied system of wormlike micelles (CPCl/NaSal) known to
exhibit both shear-banding and stress plateau behavior. Our data provide
evidence for the simplest shear-banding scenario, according to which the
effective viscosity drop in the system is due to the nucleation and growth of a
highly sheared band in the gap, whose thickness linearly increases with the
imposed shear rate. We discuss various details of the velocity profiles in all
the regions of the flow curve and emphasize on the complex, non-Newtonian
nature of the flow in the highly sheared band.Comment: 4 pages, 5 figures, submitted to Phys. Rev. Let
Trust in vehicle technology
Driver trust has potentially important implications for how vehicle technology is used and interacted with. In this paper, it will be seen how driver trust functions and how it can be understood and manipulated by insightful vehicle design. It will review the theoretical literature to define steps that can be taken to establish trust in vehicle technology in the first place, maintain trust in the long term, and even re-establish trust that has been lost along the way. The paper presents a synthesis of the wider trust literature, integrates key trust parameters, describes practically how to measure trust, and presents a set of principles for vehicle designers to use in assessing existing design decisions and justify new ones
On the evolution of credibility and flexible exchange rate target zones
This paper considers the optimal management of exchange rate target
zones by regarding the operation of a target zone as a dynamic signalling
game between the monetary authorities and the financial markets. A Sequential
Open Loop (Feedback) policy of sterilised intervention is proposed
that depends critically on the evolution of the policy maker’s credibility as opposed
to the open loop precommitment strategy that has been implemented,
for instance, in the Exchange Rate Mechanism of the EMS and in the Bretton
Woods system. The width of the target zone and re-alignments are in turn
determined optimally given the policy maker’s credibility. This flexible target zone proposal is shown through simulation to stabilize the exchange rate to
a substantial degree while retaining considerable flexibility and robustness in
response to shocks
Velocity Profiles in Slowly Sheared Bubble Rafts
Measurements of average velocity profiles in a bubble raft subjected to slow,
steady-shear demonstrate the coexistence between a flowing state and a jammed
state similar to that observed for three-dimensional foams and emulsions
[Coussot {\it et al,}, Phys. Rev. Lett. {\bf 88}, 218301 (2002)]. For
sufficiently slow shear, the flow is generated by nonlinear topological
rearrangements. We report on the connection between this short-time motion of
the bubbles and the long-time averages. We find that velocity profiles for
individual rearrangement events fluctuate, but a smooth, average velocity is
reached after averaging over only a relatively few events.Comment: typos corrected, figures revised for clarit
Upper ocean mixing controls the seasonality of planktonic foraminifer fluxes and associated strength of the carbonate pump in the oligotrophic North Atlantic
Oligotrophic regions represent up to 75% of Earth's open-ocean environments. They are thus areas of major importance in understanding the plankton community dynamics and biogeochemical fluxes. Here we present fluxes of total planktonic foraminifera and 11 planktonic foraminifer species measured at the Oceanic Flux Program (OFP) time series site in the oligotrophic Sargasso Sea, subtropical western North Atlantic Ocean. Foraminifera flux was measured at 1500 m water depth, over two ~ 2.5-year intervals: 1998–2000 and 2007–2010. We find that foraminifera flux was closely correlated with total mass flux, carbonate and organic carbon fluxes. We show that the planktonic foraminifera flux increases approximately 5-fold during the winter–spring, contributing up to ~ 40% of the total carbonate flux. This was primarily driven by increased fluxes of deeper-dwelling globorotaliid species, which contributed up to 90% of the foraminiferal-derived carbonate during late winter–early spring. Interannual variability in total foraminifera flux, and in particular fluxes of the deep-dwelling species (Globorotalia truncatulinoides, Globorotalia hirsuta and Globorotalia inflata), was related to differences in seasonal mixed layer dynamics affecting the strength of the spring phytoplankton bloom and export flux, and by the passage of mesoscale eddies. As these heavily calcified, dense carbonate tests of deeper-dwelling species (3 times denser than surface dwellers) have greater sinking rates, this implies a high seasonality of the biological carbonate pump in oligotrophic oceanic regions. Our data suggest that climate cycles, such as the North Atlantic Oscillation, which modulates nutrient supply into the euphotic zone and the strength of the spring bloom, may also in turn modulate the production and flux of these heavily calcified deep-dwelling foraminifera by increasing their food supply, thereby intensifying the biological carbonate pump

Inter-sectoral Transfer of the Food for Life Settings Framework in England
Organisational settings such as schools, workplaces and hospitals are well recognised as key environments for health promotion. Whilst there is extensive literature on specific types of settings, little empirical research has investigated the transfer of frameworks between sectors. This study analyses Food for Life, an England-wide healthy and sustainable food programme that evolved in schools and is being adapted for children's centres, universities, care homes, and hospital settings. Following a case study design, we interviewed 85 stakeholders in nine settings. Food for Life's systemic framework of 'food education, skills and experience' 'food and catering quality', 'community and partnerships' and 'leadership' carried salience in all types of settings. These were perceived to act both as principles and operational priorities for driving systemic change. However, each setting type differed in terms of the mix of facilitating factors and appropriate indicators for change. Barriers in common included the level of culture-shift required, cost perceptions and organisational complexity. For settings based health promotion practice, this study points to the importance of 'frame-working' (the systematic activity of scoping and categorising the field of change) alongside the development and application of benchmarks to stimulate change. These processes are critical in the transfer of learning from between sectors in a form that balances commonality with sufficient flexibility to adapt to specific settings. Synergy between types of settings is an under-recognised, but critical, part of action to address complex issues such as those emerging from the intersection between food, health and sustainability
