GeoTest is a project initiated by Future Position X (a GIS cluster organization in Gävle, Sweden), the National Land Survey of Sweden (NLS) and the University of Gävle. The project aims to test Swedish geodata and make sure they comply with the INSPIRE specifications in Annex I–III. The purpose of this paper is to present the development of and experiences from GeoTest in developing the require...

Third-generation mobile radio networks have been under intense research. Code division multiple access (CDMA) has emerged as the mainstream air interface solution for the third-generation networks. Multiuser detection is a necessary means for CDMA systems to reduce effect of multiple access interference and hence increase system capacity and alleviate near-far problem. The global maximum likeli...

BACKGROUND Class II furcation is a significant clinical problem in dentistry. Its presence indicates advanced periodontitis. Different xenografts are available for the treatment of involvement. Platelet concentrates that have been assimilated high concentration growth factors, which has added benefit improving and accelerating healing. T...

Publishing sensor observations on the Linked Data web is the rst step in enabling the development of semantic web applications and mashups that can utilise sensor data. We present the design for a prototype API exposing data from the Channel Coastal Observatory in the UK. By combining REST and Linked Data principles we support both Semantic Web clients, OGC GML clients, and hybrid applications ...

We present two detectors which allow multiuser detection without a side channel in a dynamic CDMA system where users are constantly leaving and entering the system. These detectors, the Maximum Likelihood (ML) and Generalized Maximum Likelihood (GML) detectors, optimally detect a new user given only the chip rate and the spreading factor of the new user. Each of these detectors produces maximum...

The system allows users to download their selected glacier data in a choice of formats. The results of a query based on spatial selection (using a mouse) or text-field constraints can be downloaded in any of these formats: ESRI shapefiles, KML (Google Earth), MapInfo, GML (Geography Markup Language) and GMT (Generic Mapping Tools). This "clip-and-ship" function allows users to download only the...

Aquaculture activities cannot be separated from obstacles that can lead to failure of aquaculture, including the presence microplastics. Microplastic polystyrene (styrofoam) is a type plastic commonly found in aquatic organisms (35%). Microplastics fish cause hormonal disturbances and high vacuolation gonads which apoptosis gonadal cells. This study aimed determine effect microplastics exposure...

Information integration has been an important area of research for many years, and the problem of integration of geographic data has recently emerged. This paper presents an approach based on the use of Ontologies for solving the problem of semantic heterogeneity in the process of the construction of a Federated Schema in the framework of geographic data. We make use of a standard technology (O...
