    Full text link
    Salah satu penarik faktor kunjungan wisatawan adalah sarana trasnportasi, dengan kemudahan sarana transportasi maka wisatawan dapat menggunakan waktunya secara efisien. Salah satu terobosan yang dianggap efektif dan membantu adalah penerapan e-money dalam pembayaran transportasi umum. Dengan menggunakan sistem e-money maka waktu yang dapat dihemat adalah 2 menit dari rata-rata penggunaan 3 menit dalam kegiatan pembayaran tiket. Kota Surabaya saat ini menyediakan sarana bus “Surabaya Shopping and Culinnary Track (SSCT)” sebagai pengembangan bidang pariwisatanya, bus tersebut membantu wisatawan mengunjungi beberapa tempat wisata, dengan beberapa rute. Peningkatan pelayanan dapat dikembangkan dengan merubah cara pembayaran dari loket manual menjadi pembayaran melalui-e-money. Dari pengguna e-money yang berada di Surabaya efisiensi time savingnya sebesar 5.709.891 menit/ orang/ hari. Dapat disimpulkan bahwa penerapan pembayaran transportasi umum yang menggunakan e-money menghasilkan 1.447.299 jam/ tahun saving time. Dimana waktu tersebut ekuivalen dengan 1.880 jam kerja/ orang/ tahun. Sehingga kota Surabaya dapat meningkatkan produktivitas kerja 769 orang/ tahun. Kata Kunci: time saving, e-money, efisiensi waktu, time ekuivale

    Novel time-saving first-principles calculation method for electron-transport properties

    We present a time-saving simulator within the framework of the density functional theory to calculate the transport properties of electrons through nanostructures suspended between semi-infinite electrodes. By introducing the Fourier transform and preconditioning conjugate-gradient algorithms into the simulator, a highly efficient performance can be achieved in determining scattering wave functions and electron-transport properties of nanostructures suspended between semi-infinite jellium electrodes. To demonstrate the performance of the present algorithms, we study the conductance of metallic nanowires and the origin of the oscillatory behavior in the conductance of an Ir nanowire. It is confirmed that the ss-dz2d_{z^2} channel of the Ir nanowire exhibits the transmission oscillation with a period of two-atom length, which is also dominant in the experimentally obtained conductance trace

    Application of response surface methodology to stiffened panel optimization

    In a multilevel optimization frame, the use of surrogate models to approximate optimization constraints allows great time saving. Among available metamodelling techniques we chose to use Neural Networks to perform regression of static mechanical criteria, namely buckling and collapse reserve factors of a stiffened panel, which are constraints of our subsystem optimization problem. Due to the highly non linear behaviour of these functions with respect to loading and design variables, we encountered some difficulties to obtain an approximation of sufficient quality on the whole design space. In particular, variations of the approximated function can be very different according to the value of loading variables. We show how a prior knowledge of the influence of the variables allows us to build an efficient Mixture of Expert model, leading to a good approximation of constraints. Optimization benchmark processes are computed to measure time saving, effects on optimum feasibility and objective value due to the use of the surrogate models as constraints. Finally we see that, while efficient, this mixture of expert model could be still improved by some additional learning techniques

    Time-Saving Innovations, Time Allocation, and Energy Use: Evidence from Canadian Households

    Time and energy are major inputs into the production of household goods and services. The introduction of time-saving innovations allows households to change their activity patterns and to reallocate their time across competing activities. As a result, the market penetration of time-saving technologies for general household use is expected to have a two-fold impact on energy use in the residential sector. Firstly, increased use of time-saving technologies for basic household chores (cooking, cleaning) can lead to a direct impact on energy use, as many time-saving technologies are more energy-intensive than technologies that require larger time commitments. Secondly, increased use of time-saving technologies allows household members to increase the amount of the activity that is undertaken (for example, when cooking requires less time, more meals may be prepared at home) or to spend more time undertaking other household chores or leisure activities (watching TV, reading, exercising) which may or may not be energy-intensive. In this paper, we use Canadian Survey of Household Energy Use data from 2003 to estimate the extent to which ownership of products that embody time-saving innovations impacts time allocation and energy use at the household level.time rebound effects; residential energy use; household production

    Economic effects of road accessibility in the Pyrenees: user perspective

    Get PDF
    At present, Spain faces one of the key moments in planning the future design of the infrastructure network. As a consequence of the critical role played by haulage in intra-European trade, the most important investments are those that guarantee that road haulage traffic can move freely at the borders. That is why it is necessary to make serious evaluations of the economic and social profitability of these investments. Normally the most significant social benefit of investment projects in transport infrastructure is time saving, which in turn changes traffic intensity. In this article we analyse the changes in the user excess caused by public investment in transport infrastructure planned by the Spanish government and which will be located on the border between Spain and France. In particular, we study the increase in network user surplus for HGV traffic in the Spanish and French border zones in the Pyrenees.Intra-European trade, time saving, user surplus, gravitational model

    Testing Contextual and Design Effects on Inter-Urban Motorists’ Responses to Time Savings

    Get PDF
    In the context of inter-urban motorists' route choices and the travel time savings offered by the UK's first toll motorway, a range of SP exercises tested various contextual and design effects. The design aspects relate to how the marginal benefit of time savings is influenced by the size and sign of the time saving, task complexity, presentation format, and whether the choice context is real. The contextual factors cover the impact of journey duration, attribute credibility, and where in the journey the time savings occur. The conclusions are largely credible but in some cases challenge established views and contribute significantly to understanding in this area
