This paper deals with a coding problem called complementary delivery, where messages from two correlated sources are jointly encoded and each decoder reproduces one of two messages using the other message as the side information. Both lossless and lossy universal complementary delivery coding schemes are investigated. In the lossless case, it is demonstrated that a universal complementary deliv...

Data mining applied to databases of data sequences generates a number of sequential patterns, which often require additional processing. The post-processing usually consists in searching the source databases for data sequences which contain a given sequential pattern or a part of it. This type of content-based querying is not well supported by RDBMSs, since the traditional optimization techniqu...

When documents are atomically structured, it is possible to assign them keyword vectors to support indexing. Most web content, however, have non-atomic structures. These include navigational/semantic hierarchies on the web. Although they are especially effective for browsing, such structures make it hard for individual nodes to be properly indexed. This is because, in many cases, their contents...

Due to the low information content of individual SAR images, single-band SAR data do not provide highly accurate land cover classification. However, in areas under risk where rapid land cover mapping is required, the advantages of SAR which include cloud penetration and day/night acquisition, are evident in comparison to optical data. The main research goal of this study is to fuse different fr...

We propose an architecture and protocol for semantically rich information retrieval from a subject-speci c corpus of information objects. The technique assumes that information objects have been labeled using small directed graphs, called content labels. A content label subsumes the role of an abstract. Both content labels and queries are required to conform with a general framework (ontology) ...

The advancement of information technology is rapidly integrating the physical world where we live and the online world where we retrieve and share information. One immediate example of such integration is the increasing popularity of storing and managing personal data using third-party web services, as part of the emerging trend of cloud computing. Secure management of sensitive data stored onl...

The structure of the adsorbing layers of native and denatured proteins (fibrinogen, gamma-immunoglobulin, albumin, and lysozyme) was studied on hydrophilic TiO(2) and hydrophobic Teflon-AF surfaces using the quartz crystal microbalance with dissipation and optical waveguide lightmode spectroscopy techniques. The density and the refractive index of the adsorbing protein layers could be determine...

Leaf area index (LAI) is a key biophysical parameter used to determine foliage cover and crop growth in environmental studies in order to assess crop yield. Frequently, plant canopy analyzers (LAI-2000) and digital cameras for hemispherical photography (DHP) are used for indirect effective plant area index (PAIe f f ) estimates. Nevertheless, these instruments are expensive and have the disadva...

We present a distributed index data structure and algorithms devised to support parallel query processing of multimedia content in search engines. We present a comparative study with a number of data structures used as indexes for metric space databases. Our optimization criteria are based on requirements for high-performance search engines. The main advantages of our proposal are efficient per...

Tissue water content and molecular microenvironment can provide important intrinsic contrast for cancer imaging. In this work, we examine the relationship between water optical spectroscopic features related to binding state and magnetic resonance imaging (MRI)-measured water diffusion dynamics. Broadband diffuse optical spectroscopic imaging (DOSI) and MR images were obtained from eight patien...
