The interest in algorithms that automatically place labels on maps, graphs, or diagrams has increased with the advance in type-setting technology and the amount of information to be visualized. However, though manually labeling a map is estimated to take fifty percent of total map production time (Morrison, 1980), most geographic information systems (GIS) offer only very basic label-placement f...

Studies were conducted on 20 rice hybrids with checks to assess the genetic variability, heritability and correlation among the genotypes for fifteen grain quality characters and grain yield. Seeds collected from the thirteen hybrids and check varieties were used for grain quality analysis. To assess the cooking qualities, a total of 30 unbroken milled grains were measured for their length and ...

On-line character recognition which can adapt to handwriting quality is proposed. In character recognition, it is di cult to recognize both clearly and roughly written characters accurately. For Japanese characters, the number of strokes is often slightly varied when characters are written roughly. In a previous method, the ranges of the number of strokes were set widely enough for recognition;...

We investigate analytically the coupling of a coplanar waveguide resonator to a coplanar waveguide feedline. Using a conformal mapping technique we obtain an expression for the characteristic mode impedances and coupling coefficients of an asymmetric multi-conductor transmission line. Leading order terms for the external quality factor and frequency shift are calculated. The obtained analytical...

Software product line are often developed through reengineering existing products and legacy applications. In such cases it is not uncommon for the behavioural and quality characteristics of individual product architectures to be inconsistent with those of the common architecture. Successful development of product lines dictate that those inconsistencies be resolved. The resolution process invo...

A statistical study of data containing observations of process and quality variables from the SCA paper mill in Munksund, Sweden, is presented. The emphasis in this analysis has been on modelling the laboratory collected paper quality variables by means of the data available on-line, during production. The primary tool for prediction, or estimation at non observed time instants, of variables wa...

Voltage sag is an important power quality problem, which may affect domestic, industrial and commercial customers. Voltage sags may either decrease or increase in the magnitude of system voltage due to faults or change in loads. Momentary and sustained over voltage and under voltage ma y cause the equipment to trip out, which is highly undesirable in certain application. In order to maintain th...

In computerized adaptive testing, updating parameter estimates using adaptive testing data is often called online calibration. In this paper, how to evaluate whether the adaptive testing model used for online calibration fits the item response model used sufficiently is studied. Three approaches are investigated, based on a Lagrange multiplier (LM) statistic (J. Aitchison and S. Silvey, 1958), ...

The aim of this work is to present the functionalities and first results of an automatic system on quality control and patient dosimetry for diagnostic radiology, and its application to computed tomography (CT) in a big university hospital. The system is directly connected to the PACS (Picture Archive an Communication System) of the hospital and extracts useful information contained in the DICO...

We use data from an on-line market for programming services to assess buyers’ welfare gains associated with the globalization of this service market enabled by the Internet. Our study exploits the design of this market where projects are allocated through multi-attribute auctions, a mechanism that takes into account a seller’s non-price characteristics as well as his bid. We focus on the increa...
