Many applications, including smart environments, surveillance, human-robot interaction, and ambient assisted living, involve the problem of learning patterns of agent behavior from sensor data. Deviant behavior is a pattern in the data that either does not conform to the expected behavior, that is, anomalous behavior, or matches previously defined unwanted …

Dielectric materials, used to control and store charges and electric energy, play a key role in modern electronics and electric power systems. Dielectric spectroscopy is a versatile method, well-suited for detection, separation and characterization of various contributions to dielectric response of advanced ceramic and polymeric materials, as it enables understanding …

The domain of data mining (DM) deals with analyzing different types of data. The data typically used in data mining is in the format of a single table, with primitive datatypes as attributes. However, structured (complex) data, such as graphs, sequences, networks, text, image, multimedia and relational data, are receiving …

Titanium dioxide (TiO2) in nanoparticle form has recently gained a lot of attention, in both the scientific and industrial communities. This is due to the fact that it exhibits various interesting chemical and physical characteristics, for example, a high photocatalytic activity and the absorption of incident UV light. Many applications …

SRAM-based FPGAs have become an attractive solution for many applications where a short development time, low-cost for low-production volumes, and in-the-field-programming ability are important issues. The flexibility of SRAM-based FPGAs comes from the adoption of a configuration memory that defines the operations of the circuit that the FPGA implements. It …

Adaptation to altitude can enhance performance if the hypoxic dose and the frequency of the exposures are appropriate. While many hypoxic training modalities exist, the protocols utilizing short intermittent hypoxic exposures are gaining popularity. However, the effects of such novel hypoxic protocols on athletic performance are unclear. The aim of …

Minimally invasive surgery is one of the most promising trends in medicine. Despite of its obvious advantages - the use of small incisions reducing trauma and risk of infection - it still represents a great challenge for the surgeon, as visual guidance and dexterity are severely impaired. In the case …

Over the last decade we have been witnessing rapid development of telecommunication networks and services, in particular in the filed of new wireless network technologies. On different markets users are able to communicate using different wireless technologies. The first two generation of mobile networks (i.e. NMT and GSM) were developed …

The stress dependence of the electrical permittivity offers a convenient way of measuring pressure. This effect is suitable for static and quasi-static stress applications, where the conventional method based on the piezoelectric effect becomes inadequate. Although the principle of applying this effect for pressure sensing has been known for almost …

Thin film nanocomposites consisting of inorganic matter embedded within a soft polymeric matrix on the nanometer scale have attracted much interest lately due to their unique properties with potential application in optoelectronics and photonics. Polyelectrolyte multilayers formed by the layer-by-layer electrostatic assembly of oppositively charged polyions can be utilized as …
