Mapping of user interfaces on electronic appliances

The purpose of this study was to investigate mapping of user interfaces on consumer electronic appliances. A digital clock with five different interface modes was chosen for the experiment. Forty elderly subjects (above 65 years) and 40 middle-aged subjects (45-64 years) participated in the study. Every subject had to complete three different tasks, namely time setting, alarm time setting and date setting. The researchers investigated what problems were encountered when performing these tasks and collected data such as operational time, the number of total inputs, subjective estimation and interview information. The findings of this study indicated that the interface modes had significant effects on operational time, the number of total inputs and subjective estimation. Finally, the study confirms that when the spatial relationship between buttons and display contents are clearly indicated, the operation is easier to complete.     

New methodologies for geological surveys

Within the context of Quaternary geology, current developments in the automation of survey data aim at mechanization of traditional data-handling techniques. In this type of automation, computer systems are asked to perform tasks at which they are slow, clumsy, and expensive. The need for continuous human support makes conventional automation unattractive.Traditional geological survey methodology has developed within the framework of manual data-handling techniques. The sampling design, data compression and generalization, the stratigraphic map all illustrate our inability to return to the only hard facts available: the observed boreholes and outcrops and their attributes.The computer can liberate us from most of these constraints. New sampling designs will be based on recent work in geostatistics. Information from existing archives may be captured through free-language processing, new borelogs will be recorded directly on magnetic medium. Lithological and stratigraphic interpretation will be automated and rely on numerical classification techniques. Traditional map drawing will disappear, the general purpose map will be replaced by special purpose univariate and multivariate maps computed directly from borelogs, but influenced by subjective point, line and area data.Experiments with the Quaternary by the Dutch geological survey are used to illustrate the feasibility of this alternative automation. The steps Input (free-language processing), Stratigraphic identification (interactive allocation), and Map construction (multivariate automated mapping) are illustrated.     

Interpretation of regional geochemistry using optimal interpolation parameters

A collection of data analysis procedures is presented which are derived from estimation of geographic interpolation parameters. Several interpolation models are discussed along with a procedure to obtain the best model. The power parameter, p, and the search radius, c, are the standard parameters in inverse distance weighting interpolation which is appropriate for sampling patterns that are not highly irregular. The power parameter is shown to characterize the regional behavior of geochemical measurements. This characterization process can be used to associate similar types of geochemical measurements, produce optimal contour maps, derive meaningful residual maps, and highlight unusual geochemical areas by a weighted sum variable. The computer program. BESTP, (used to estimate the optimum inverse distance weighting interpolation parameters) is presented, along with an example using reconnaissance groundwater data from the Plainview Quadrangle, Texas.

A Mapping Framework Based on Packing for Design Space Exploration of Heterogeneous MPSoCs

The computational demand of signal processing algorithms is rising continuously. Heterogeneous embedded multiprocessor systems-on-chips are one solution to satisfy this demand. But to be able to take advantage of these systems, new strategies are required to map applications to such a system and to evaluate the systems performance at a very early design stage. We will present a framework for static, analytical, bottom-up temporal and spatial mapping of applications to MPSoCs based on packing. This mapping framework allows easy performance evaluation and design space exploration of heterogeneous systems on chip.

Classification of normal and abnormal samples of peripheral blood by linear mapping of the feature space

A data set of features derived from digitized images of monocytes and lymphocytes taken from samples of normal persons (10 cases) and from persons with either Hodgkin's disease (10 cases) or non-Hodgkin's lymphoma (9 cases) was explored. The morphological characteristics of a small proportion of the cells in the abnormal samples may well provide indications of the abnormality.A linear mapping of the feature space is described. This technique may be used to visualize the abnormality of the sample and to design a decision rule, applicable to independent test samples.     

ISO: A Fortran IV Program for Generating Isopleth maps on Small Computers

The construction of computer-generated isopleth maps has been limited generally to large computer programs such as SYMAP and AUTOMAP II. These programs may require machines with large amounts of memory. Large machines are not available to many potential users. This paper describes the program ISO, which is designed to create isopleth maps on small- and medium-size computers. ISO complements the CMAP program developed to produce chloropleth maps on small computers and employs many of the features used in CMAP. It also provides some additional features such as limited map cosmetic capability, internal storage of scan lines for multiple map runs, and greater operational convenience in establishing map categories, symbols, and text. Proximal maps also can be generated by ISO.     

Wrapping of Web Sources with restricted Query Interfaces by Query Tunneling

Information sources in the World Wide Web usually offer two different schemes to their users, an Interface Schema which the user can query and a Result Schema which the user can browse. Often the Interface Schema is more restricted than the Result Schema, moreover many sources offer keyword-search interfaces only. Thus query capabilities of such sources are very small and a useful integration into a mediator-based information system using query capabilities is almost impossible. We propose the Query Tunnelling architecture for the wrapping of these restricted web sources. Wrapping of sources by Query Tunneling hides restrictive query interfaces and makes such sources fully queryable based on their result schema. The process of Query Tunneling is divided into two main steps, Query Relaxation to make a higher order query suitable to a restricted interface and Result Restriction in order to filter the results using the original query.
