Complex Cepstrum in Speech Synthesi
Vondra, Martin ; Vích, Robert
In the contribution the use of the complex cepstrum in speech modeling and synthesis is shortly described. The obtained mixed phase parametric speech model is of the finite impulse response type and contains also information about the phase properties of the modeled speech frame. The synthesized speech is more natural, but the memory requirements and numerical complexity are much higher than for minimum phase realization.

Surface plasmon resonance biosensors: present and future
Homola, Jiří
Optical biosensors based on the surface plasmon resonance (SPR) have become important tool for real-time study of biomolecular interactions and for detection of various analytes in fields such as food safety, medical diagnostics, or environmental monitoring. This paper reviews the present state of the art in the development of SPR sensor technology, discusses emerging trends, and presents selected results of research into SPR sensors at the Institute of Photonics and Electronics, Prague.

Fiber lasers
Peterka, Pavel
Fiber lasers are one of the most spectacular achievements of contemporary optoelectronics and photonics. Variety of fiber lasers were demonstrated ranging from mighty continuous-wave systems with multi-kilowatt output powers to elegant femtosecond-pulse sources for precise frequency and time measurements. In the contribution, we present basic principles and applications of these new sources of laser radiation and we present selected research results in this field in the Institute of Photonics and Electronics.

Respiratory and cardiovascular health effects of nanoparticles
Nohavica, Dušan
Numerous combustion related and natural sources generate airborne ultra fine particulate matter (<100 nm). Several epidemiological studies have found adverse respiratory and cardiovascular health effects in susceptible parts of the population to be associated with these particles. Published clinical studies with 10-50 μg/m3 ultra fine elemental carbon particles as surrogates for ambient particles did induce cardiovascular effects in healthy adults.
