Carbon monoxide inhaled into the lungs will enter blood circulation and inhibit entry of oxygen needed by body. This gas combines with hemoglobin to form carboxyhemoglobin (COHb). The increase in COHb function transportation affect health workers. study aims determine risk factors for increasing Tirtonadi Bus Station Surakarta officers. research method used analytic observational a cross-sectio...

This paper develops behavior models to analyze traveler propensity towards a new ‘‘very light jet”-based on-demand air service (ODAS), also labeled air taxi service, with the broader objective of providing guidance for the enabling stakeholders including business operators, policy-makers and aircraft manufacturers. The models predict the probability of individuals switching from their usual pre...

 The meeting will take place at the UoC Seminar Building, Conference Room (" Tagungsraum " , ground floor), Universitätsstraße 37, 50931 Cologne.  If you arrive at the main train station (Dom/Hbf) take subway/tram lines 16 or 18 (platform 1) to Neumarkt. At Neumarkt, take line 9 (platform 4, direction Sülz) to Universität. From there it's a short walk to the building.  If you arrive at the t...

We assume that m facility units (hospital, bank, post office, fire department, police station, bus station, etc.) are requested to be established for n cities which are on the same line. We have to choose m cities where the facility units will be established such that total distance from all cities to nearest facility units is minimum. Here, it is supposed that the person who is in the city whi...

Wireless radios are a great consumer of energy in sensor networks. Retrieving data from a remote deployment in an energy-efficient fashion is a difficult problem, and while solutions have been proposed in literature, real-world systems typically implement robust though inefficient methods. In an effort to bring efficient monitoring techniques to real-world environmental sensor networks, we seek...

The local network medium is a pair of unidirectional fiber optic busses to which stations are conneted via passive taps. For this configuration, a new random-access protocol called RATO (randomaccess, time-out) is presented in this paper. This RATO provides random-access, fairness, and bounded delay access to all stations, and is particularly suited for ultra-high-speed transmission when the pe...

The Distributed Queue Dual Bus (DQDB) protocol or IEEE 802.6 has been accepted as the international standard for Metropolitan Area Networks (MAN). This paper describes a combined M/G/1 and Markov model for the steady state performance analysis of a DQDB network. In the analysis each station is considered independently, but not in isolation, thus avoiding the computational complexity which would...

This study examines if tourists actively inform themselves about the climate of their planned destination. In addition, we examine where they inform themselves and at what point in the holiday decision-making process. A self-administered questionnaire was distributed to tourists at the airport, international bus station, and the train station in Hamburg during July and August 2004. Of the 394 r...

Public-transportation route-planning systems typically work as follows. The user specifies a source and a target location, as well as a departure time. The system then returns one or more optimal trips at or after that departure time. In this paper, we consider guidebook routing, where the goal is to provide timeindependent answers that are valid over long periods of time. An example answer cou...

Several decades ago, during my teenage years in the 1970s, I attended a grammar school near Reigate in Surrey. Every weekday morning for seven years, I would take an early train from Horley to Redhill, before walking or catching a bus from there to the school. As the train travelled northwards on its way to Redhill (and on to London), it passed through a small, often seemingly abandoned, statio...
