New admissions system that existedat this school has been using a computer but still using a simple application, so often there is a delayin the presentation of information, so there needs to be a new system that can improve the existingsystem. To resolve this problem, the school needs to use the new system with a computerized systemthat has a better database to store its data. With a computerized system that better data processingwill be more efficient and to minimize errors in the data pengimputan. Thus the new admissionssystem that there will be better and can improve service to masarakat who want to registe
Fusion of functional brain imaging modalities via linear programming.
Proposed method makes a number of simplifying assumptions which convert the EEG/FMRI integration problem into optimization of a convex function, of a form amenable to efficient solution as a very sparse linear programming (LP) problem. The assumptions made in doing this are, surprisingly, in general somewhat more robust than those generally used to cast EEG/FMRI integration as optimization of a non-convex function not amenable to efficient global optimization. This is because the L1 norm used here corresponds to a more robust statistical estimator than the L2 normal generally used For this reason, even though this technique results in a tractable global optimization, it is more robust to non-Gaussian noise and outliers than approaches that make the Gaussian noise assumption [1]. Current poster presents formulation of the problem together with results obtained on artificial data
Thermal Diffusion and Diffusion Thermo Effects on MHD Thermosolutal Marangoni Convection Boundary Layer Flow over a Permeable Surface
The problem of thermal diffusion and diffusion thermo effects on thermosolutal Marangoni convection flow of an electrically conducting fluid over a permeable surface is investigated. Using appropriate similarity transformations, the governing system of partial differential equation is transformed to a set of nonlinear ordinary differential equations, then solved numerically using the Runge-Kutta-Fehlberg method. The effects of thermal diffusion and diffusion thermo, magnetic field parameter, thermosolutal surface tension ratio, and suction/injection parameter on the flow field, heat transfer characteristic, and concentration are thoroughly examined. Numerical results are obtained for temperature and concentration profiles as well as the local Nusselt and Sherwood numbers are presented graphically and analyzed. It is found that these governing parameters affect the variations of the temperature and concentration and also the local Nusselt and Sherwood numbers

Investigation Of Copper(I)Thiocyanate (CuSCN) As A Hole Transporting Layer For Perovskite Solar Cells Application
Copper(I) Thiocyanate (CuSCN) is an inorganic hole transporting layer (HTL) used in perovskite solar cells (PSC). This material offers higher stability and reliability compared to conventional HTL. In this work, for depositing CuSCN (inorganic compound) we were using spin coating technique. The annealing temperature of CuSCN is varied in order to analyze the structural and electrical characteristics. The structural characteristics are determined by scanning electron microscopy (SEM), Raman spectroscopy and X-ray diffraction (XRD). Meanwhile, the electrical characteristic is measured by the I-V characteristics measurement. SEM images show the material surface features such as crystallinity morphology and density. XRD and Raman spectroscopy are used to confirm the coated surface on the ITO substrate is CuSCN. Besides, the I-V characteristic reveals that the conductivity with respect to
annealing temperature. As a result, the optimized annealing temperature of CuSCN is 80 °C and showing conductivity of 62.96 S/m. In conclusion, CuSCN has a significant conductivity, hence suitable for the application as the HTL for perovskite solar cells
A reduced integer programming model for the ferry scheduling problem
We present an integer programming model for the ferry scheduling problem,
improving existing models in various ways. In particular, our model has reduced
size in terms of the number of variables and constraints compared to existing
models by a factor of approximately O(n), where n being the number of ports.
The model also handles efficiently load/unload time constraints, crew
scheduling and passenger transfers. Experiments using real world data produced
high quality solutions in 12 hours using CPLEX 12.4 with a performance
guarantee of within 15% of optimality, on average. This establishes that using
a general purpose integer programming solver is a viable alternative in solving
the ferry scheduling problem of moderate size.Comment: To appear in Public Transpor
Building a transnational biodiversity geo-database of the protected areas in the Adriatic-Ionian Macro-Region: approaches and results from the IMPRECO Project
Background The main objective of the project Common strategies and best practices to IMprove the transnational PRotection of ECOsystem integrity and services - IMPRECO is to enhance the safeguarding of ecosystems and ecosystem services. Additionally, the aim of this project is to tackle their environmental vulnerability by strengthening the potential of the Protected Areas in biodiversity, ecosystems and ecosystem services conservation. This is expected to be addressed by maintaining it through their transnational networking located in the European Adriatic-Ionian Macro-Region. New information The aim of this research is: 1) to characterise the habitats and ecosystems involved in the coastal-marine protected areas considered; 2) to set a biodiversity baseline; 3) to understand what current ecosystems' conditions are; 4) to build up a transnational biomonitoring programme of target species and habitats and 5) to assess their response to pilot actions. To do so, a transnational inventory of species, habitats, ecosystems and ecosystem services was established, starting with the seven coastal-marine protected areas involved in the project. Data collection was carried out using different sources of information: scientific literature, officially available data from NATURA 2000 Standard Data Forms, checklists from local biomonitoring programmes, personal observations and citizen science, historical maps and data from new in-field analyses. Data were filled in the transnational biodiversity geo-databases according to the NATURA 2000 standards about habitat features, species protection level and species features. The presence of alien species (non-indigenous species, NIS) was also acknowledged and references about data collection were provided in the databases according to the Darwin Core standards
Changing climate both increases and decreases European river floods
Climate change has led to concerns about increasing river floods resulting from the greater water-holding capacity of a warmer atmosphere1. These concerns are reinforced by evidence of increasing economic losses associated with flooding in many parts of the world, including Europe2. Any changes in river floods would have lasting implications for the design of flood protection measures and flood risk zoning. However, existing studies have been unable to identify a consistent continental-scale climatic-change signal in flood discharge observations in Europe3, because of the limited spatial coverage and number of hydrometric stations. Here we demonstrate clear regional patterns of both increases and decreases in observed river flood discharges in the past five decades in Europe, which are manifestations of a changing climate. Our results\u2014arising from the most complete database of European flooding so far\u2014suggest that: increasing autumn and winter rainfall has resulted in increasing floods in northwestern Europe; decreasing precipitation and increasing evaporation have led to decreasing floods in medium and large catchments in southern Europe; and decreasing snow cover and snowmelt, resulting from warmer temperatures, have led to decreasing floods in eastern Europe. Regional flood discharge trends in Europe range from an increase of about 11 per cent per decade to a decrease of 23 per cent. Notwithstanding the spatial and temporal heterogeneity of the observational record, the flood changes identified here are broadly consistent with climate model projections for the next century4,5, suggesting that climate-driven changes are already happening and supporting calls for the consideration of climate change in flood risk management
