Simulation of a manufacturing cell requires the different kinds of simulation models of manufacturing stations that constitute the cell. However, a commercial station simulator only gives simulation mechanism for a limited kind of station, and its simulation model is fixed to the engineer. On the other hand, it is inefficient for the engineer to develop the dedicated simulation model and mechan...

Consider a production system that consists of m assembly stations arranged in series. All jobs enter the assembly line at station 1 and proceed with subsequent stations in the same order as in a ßow shop. Each job spends a Þxed amount of time c in each station, known as the production cycle. This production system is synchronous or paced because jobs move one station forward synchronously, ever...

The techniques used in GSM networks for mobile station localization typically use several methods with different level of granularity, based on the base network parameters such as Cell Identification, Timing Advance, the position of Base Transceiver Station, the parameters of Base Transceiver Station antenna etc. This article introduces several others parameters that can be used for network des...

We present the construction of a continuous, daily (09:00 UTC), station-based (Azores-Iceland) North Atlantic Oscillation (NAO) Index back to 1871 which is extended back to 1850 with additional daily mean data. The constructed index more than doubles the length of previously existing, widely available, daily NAO time series. The index is created using entirely observational sea-level pressure (...

Analyses of stratospheric ozone data determined from Dobson–Umkehr measurements since 1977 at the Syowa (69.0 S, 39.6 E), Antarctica, station show a significant decrease in ozone at altitudes higher than that of the 4 hPa pressure level during the 1980s and 1990s. Ozone values over Syowa have remained low since 2001. The time series of upper stratospheric ozone from the homogenized NOAA SBUV (S...

[1] We compare versions of six interpolation methods for the interpolation of daily precipitation, mean, minimum and maximum temperature, and sea level pressure from station data over Europe from 1961 to 1990. The interpolation methods evaluated are global and local kriging, two versions of angular distance weighting, natural neighbor interpolation, regression, 2D and 3D thin plate splines, and...
