Multiproduct Uniform Polar Quantizer

The aim of this paper is to reduce the complexity of the unrestricted uniform polar quantizer (UUPQ), keeping its high performances. To achieve this, in this paper we propose the multiproduct uniform polar quantizer (MUPQ), where several consecutive magnitude levels are joined in segments and within each segment the uniform product quantization is performed (i.e. all levels within one segments have the same number of phase levels). MUPQ is much simpler for realization than UUPQ, but it achieves similar performances as UUPQ. Since MUPQ has low complexity and achieves much better performances than the scalar uniform quantizer, it can be widely used instead of scalar uniform quantizers to improve performances, for any signal with the Gaussian distribution

Semilogarithmic Nonuniform Vector Quantization of Two-Dimensional Laplacean Source for Small Variance Dynamics

In this paper high dynamic range nonuniform two-dimensional vector quantization model for Laplacean source was provided. Semilogarithmic A-law compression characteristic was used as radial scalar compression characteristic of two-dimensional vector quantization. Optimal number value of concentric quantization domains (amplitude levels) is expressed in the function of parameter A. Exact distortion analysis with obtained closed form expressions is provided. It has been shown that proposed model provides high SQNR values in wide range of variances, and overachieves quality obtained by scalar A-law quantization at same bit rate, so it can be used in various switching and adaptation implementations for realization of high quality signal compression

PIXEL 2010 - a Resume

The Pixel 2010 conference focused on semiconductor pixel detectors for particle tracking/vertexing as well as for imaging, in particular for synchrotron light sources and XFELs. The big LHC hybrid pixel detectors have impressively started showing their capabilities. X-ray imaging detectors, also using the hybrid pixel technology, have greatly advanced the experimental possibilities for diiffraction experiments. Monolithic or semi-monolithic devices like CMOS active pixels and DEPFET pixels have now reached a state such that complete vertex detectors for RHIC and superKEKB are being built with these technologies. Finally, new advances towards fully monolithic active pixel detectors, featuring full CMOS electronics merged with efficient signal charge collection, exploiting standard CMOS technologies, SOI and/or 3D integration, show the path for the future. This r\'esum\'e attempts to extract the main statements of the results and developments presented at this conference.Comment: 8 pages, 19 figures, conference summar

Pigment identification with optical coherence tomography and multispectral imaging

We describe a new method for non-invasive pigment identification by combining the spectral reflectance in the visible spectrum with near infrared OCT cross-section images of the subsurface layer structure

Financial Measures and Instruments for Adjustment of Agriculture for EU Accession

Agricultural development is the first and the main priority of the Republic of Croatia. Agricultural land comprises more than a half of te land area of the Republic of Croatia, almost 48 % of the population live in rural areas and the share of agriculture in GNP amounts to approximately 10%. Since the Republic of Croatia wants to join the EU in near future various sorts of harmonisation of Croatian legislature with acquis communautaire are necessary. The process of harmonisation in the field of agriculture is especially demanding and multi-layered. Sustainability and multifunctionality of agricultural production and rural regions are the very bases of modern agricultural policy in the most developed countries, including the EU. The negotiations held on agriculture between the Republic of Croatia and the EU make even 50% of the total negotiations, which additionally emphasizes the importance of agriculture. Competitiveness of the national agriculture can increase substantially with the help of the preaccession funds, which is the topic of the paper. SAPARD stands out as the most important among them; within this fond the Republic of Croatia can have use of 25 million euros. The same amount is provided for the new preaccession fund IPARD that will replace SAPARD next year. The aims of these funds are to prepare the candidate countries, i.e. Croatia for their participation in EU common market when it comes to accession.agriculture, EU, preaccession funds, SAPARD, IPARD
