Signaling data of cellular phones can be used as valuable information for state-of-the-art traffic applications especially in urban areas. The traces of mobiles like handovers and location area updates may be efficiently utilized in the field of road traffic measurement and forecasting or even traffic control. By detecting and processing the locomotion of anonymous mobile phones, origin-destina...

This paper presents FLOWTEST a concept on testing interorganizational workflows on model-level. FLOWTEST focuses on building up test-models, deriving test-cases and executing tests on predefined workflows consisting of atomic web-services. The main goal of FLOWTEST is the realization of a test-suite to drive round-trip testing from code to model back to code level.

Energy storage systems are well poised to mitigate uncertainties of renewable generation outputs. Gridscale energy storage projects are major investments which call for rigorous valuation and risk analysis. This paper provides a stochastic energy storage valuation framework in wholesale power markets which considers all key revenue streams simultaneously. As part of this framework, an operation...

In this paper we describe our effort on TREC 2015 Contextual Suggestion Track. Using opinions from online resources to model both user profile and candidate profile has been proven to be effective on previous TREC. This year we also leverage the power of building profile based on opinions. Opinions from well known commercial online resources are collected in order to build the profiles. Two kin...

When searching for flights, current systems often suggest routes involving waiting times at stopovers. There might exist alternative routes which are more attractive from a touristic perspective because their duration is not necessarily much longer while offering enough time in an appropriate place. Choosing among such alternatives requires additional planning efforts to make sure that e.g. poi...

A 40-year-old man with the acquired immunodeficiency syndrome (AIDS) was admitted for evaluation of dyspnea, nonproductive cough, and fever of five days' duration. Six months earlier, he had been treated at another hospital for Pneumocystis carinii pneumonia and was subsequently begun on therapy with 3T-azido-3'-deoxythymidine (AZT). His past medical history was remarkable for the presence of a...

In this paper, we present a high accuracy laser range finder and velocimeter using ultra-fast time-to-digital converter (TDC). The system operation is based on the measuring the round-trip time of a narrow laser pulse. A low-dark current high-speed PIN photodiode is used to detect the triggered laser beam and to produce start signal. The pulsed laser diode generates 45W optical power at 30ns du...

Abstract This study aims to identify the demand estimation of passengers regarding operational railway Maros-Barru line. The new is expected attract using public transport from origin destination. existing condition majority used private vehicle as choice and minibus with fragmented construction provided by government services through Maros-Barru. for plays an important role in describing poten...

This study analyzes the effect of accessibility to jobs and houses at both the home and work ends of trips on commuting duration for respondents to a household travel survey in metropolitan Washington, DC. A model is constructed to estimate the effects of demographics and relative location on the journey to work. Analysis finds that residences in job-rich areas and workplaces in housing-rich ar...

Methods: Uniquely comparable national travel surveys for the U.S. (NHTS 2001 and 2009) and Germany (MiD 2002 and 2008) were used to calculate the number, duration, and distance of active trips per capita. The population-weighted person and trip fıles for each survey were merged to calculate population levels of anywalking/cycling, walking/cycling 30minutes/day, and achieving 30 minutes in bouts...
