Opis:
Floating point (FP) multiply-accumulate (MAC) represents one of the most important operations in a wide range of applications, such as DSP, multimedia or graphic processing. This paper presents a FP MAC half precision (16-bit) FPGA implementation. The main contribution of this work is represented by the utilization of modern FPGA DSP block for performing both mantissa multiplication and mantissa accumulation. In order to use the DSP block for these operations, the alignment right shifts are performed before the multiply-add stage: a right shift on one of the multiplicand, and, a left shift for the other. This results in efficient DSP usage; thus both cost savings and higher performance (high working frequencies and low latencies) are targeted for MAC operations.

Opis:
In this paper, we investigated the transient electron population and the transient behaviour of the dispersion, absorption and refractive property of weak probe light in a four-level InGaN/GaN quantum dot nanostructure. In order to achieve the wave functions and their corresponding energy levels of the mentioned quantum dot nanostructure, the Schrödinger and Poisson equations is solved selfconsistently for carriers (here electron) in quantum dot. Our findings show that the properties of transient processes can be dramatically affected by parameters such as intensity, detuning and relative phase of applied fields. Our proposed scheme provides a realistic model for transient control of refraction index properties in a quantum dot nanostructure. These results may have potential applications in high speed optical switch for quantum information technologies.

Opis:
Dot-immunobinding technique was used to detect circulating Toxoplasma antigens in the sera of men and animals. Serum samples were collected from mice and rabbits infected experimentally with parasites of the RH strain of T. gondii while human sera were obtained from persons suspected of having active toxoplasmosis. Circulating Toxoplasma antigens were detected in the samples of mice sera that had been collected since the 2-nd day of iniection and in the sera of rabbits during 2 and 3 week of iniection. From amongst 146 human sera, 35 (24%) gave positive reaction in the test while 14 (9,5%) produced doubtful results. The experiments proved the method to be sensitive, reproducible and easy to perform. It obviates the need of special equipment while most of the necessary reagents are commercially available. High percentage of doubtful results is the main drawback of the method.

W artykule zanalizowano i oceniono możliwości opracowania map z zastosowaniem wybranych form prezentacji kartograficznej w jednym z programów typu GIS - MapInfo Professional. Kolejno omówiono opracowane w programie mapy kropkowe, izoliniowe, sygnaturowe, chorochromatyczne oraz mapy zasięgów. Podjęto próbę zweryfikowania poprawności rozwiązań metodycznych zastosowanych w programie i opisanych w podręcznikach użytkownika programu MapInfo.
There is no doubt that the use of GIS type programs is widespread. Almost any computer literate person who wants to experiment with the possibilities of the program is able to make an attempt to create a map or another graphic presentation. In the previous issue of Polish Cartographical Review, choropleth and proportional symbol presentation possibilities of the MapInfo Professional 10.5 program were evaluated. This article discusses and evaluates the remaining methods of cartographic presentation: the dot method, the isoline method, the signature method, the qualitative background method and the ranges method from the point of view of their cartographical correctness. Attempts to create maps in MapInfo have shown that proposed solutions are not fully correct and adequate. Relatively low general evaluation of the program results from its numerous mistakes and missing sections of instructions which often hinder the process of proper map elaboration instead of facilitating it. Despite the fact that MapInfo Professional contains a lot of useful functions, it is not fully developed and sometimes can even mislead the program user. Nevertheless it seems to have considerable potential to become a useful tool in editing correct maps. In order to do it, however, it should comply with the rules of cartography. Although GIS-type programs are supposed to present cartographic data adequately, it should be remembered that in many instances their default automatic options are insufficient. Possibility of creating a software which would allow a non-professional user (with no cartographic skills) to make a correct map is an issue to be considered.

Opis:
Choć obecnie mapy tematyczne są powszechnie używane, ich zastosowanie w zarządzaniu nieruchomościami Skarbu Państwa jest czymś nowym. Jak dotąd do tego typu analiz stosowano głównie zestawienia tabelaryczne i wykresy. W prezentowanym artykule przedstawiono propozycję wykorzystania map tematycznych jako elementu wspierającego efektywne zarządzanie nieruchomościami państwowej jednostki organizacyjnej jaką jest Policja. Wykonane mapy tematyczne, poprzez zastosowanie różnego rodzaju metod prezentacji kartograficznej – kartodiagramów (słupkowych, kołowych), map przedziałów (kartogramów) opracowanych w oprogramowaniu ArcView firmy ESRI oraz MapInfo firmy MapInfo Corporation umożliwiły przeprowadzenie analiz czasowych i jednocześnie wielowątkowych.
While thematic maps are now widely used, their use in the property management is rather new. So far data about property, in property management systems, is visualized mainly in the form of table charts and diagrams. This article presents the possibility of use thematic maps as an element of support for the effective management of Police’s state property entity. For the Police, as managers, thematic maps will meet a number of functions: diagnostic – to allow analysis of current state, control and account – allowing the rationalization of expenditures, and – prognostic – facilitate the realization of strategic goals. Statistical data on managed properties, such as facilities maintenance costs, obtained from the Police Headquarters, were the basis for mapping and analysis. Thematic maps made by applying various methods of cartographic presentation – cartodiagrams (charts), maps of compartments (choropleth map) in software developed by ESRI ArcInfo and MapInfo (developed by MapInfo Corporation) give possibilities of exploratory and multi analysis. The use of thematic maps in the property management system allows the Police on the one hand presentation the descriptive data collected by the Police about the managed property, on the other hand gives the possibility of further analysis and research by seeking spatial and temporal relationships between data on Police Headquarters or stations, and determine their dynamics, and other laws.

Opis:
An edge of a graph is called dot-critical if its contraction decreases the domination number. A graph is said to be dot-critical if all of its edges are dot-critical. A vertex of a graph is called critical if its deletion decreases the domination number. In A note on the domination dot-critical graphs, Discrete Appl. Math. 157 (2009) 3743-3745, Chen and Shiu constructed for each even integer k ≥ 4 infinitely many k-dot-critical graphs G with no critical vertices and κ(G) = 1. In this paper, we refine their result and construct for integers k ≥ 4 and l ≥ 1 infinitely many k-dot-critical graphs G with no critical vertices, κ(G) = 1 and λ(G) = l. Furthermore, we prove that every 3-dot- critical graph with no critical vertices is 3-connected, and it is best possible.

In this paper, we will discuss the Goos–Hänchen shifts properties of reflected and transmitted light beams from the cavity with four-level InGaN/GaN quantum dots nanostructure. We find that the Goos–Hänchen shifts properties of reflected and transmitted light beams can be controlled via adjusting the refractive index of four-level quantum dot nanostructure. Here, we show that by tunable infrared laser field the negative refraction index can be possible at certain values of probe frequency. Therefore, the large Goos–Hänchen shifts for reflected and transmitted light beams are possible for negative refractive index condition.

Here, we will show that the output-input properties of the system can be adjusted by the Fano-interference strength, amplitude and the relative phase of the driving fields, respectively. Also, we consider the thickness effect of defect medium on controlling the output-input behaviors of probe light. Moreover, we realize that it is possible to switch between optical bistability and optical multistability by optimizing the conditions which are more practical in all-optical switching based nanoscale devices.

Opis:
HPM meters are required for the assessment of fields generated by sources of high-power microwaves. Finding the inverse calibration curves for such instruments is important for ensuring accuracy. The procedure is relatively simple for meters consisting of linear devices but there can also be hardware solutions implementing nonlinear ones. The objective of the present work was to develop a convenient procedure to allow finding such a curve when the meter uses a D-dot probe and a power detector. For that purpose, the results of low voltage measurements describing the properties of the detector were first analysed. Then a software code was developed to estimate the RMS value of an incident field based on measured output and frequency response. The response was estimated with very low electric field. And finally, the performance of the proposed procedure was verified by tests conducted with high electric field in a TEM cell. High conformity of the output of the meter with fields of known values was demonstrated. The maximum error related to the meter range did not exceed 4%.

Opis:
The electronic structures and optical matrix elements of CdSe semiconductor quantum dots of near cubical, hemispherical and cylindrical shape embedded in ZnSe were calculated. Bulk Hamiltonian matrices were obtained using the empirical tight binding method including spin-orbital coupling and relativistic effects. All quantum dots were simulated in reciprocal space and the number of atoms in each quantum dot was kept nearly equal for the comparison purpose. An adjacency matrix was produced which indicates the adjacencies of unit cells and the bulk Hamiltonian was included for each adjacency point in order to obtain the quantum dot Hamiltonians. The strain effects, valence band offset and spin orbital coupling were included in the calculations. The quantum dot Hamiltonian was solved to obtain the highest and lowest eigenvalues from which the electronic structure was obtained. Then eigenvalues near integers ranging from the lowest eigenvalue to highest eigenvalue was generated for the point.

Opis:
We theoretically investigate power-induced lasing state switching and bistability in a two-state quantum dot laser subject to optical injection. The simulated results show that, for a free-running two-state quantum dot laser operating at the ground state under low current, a power-induced lasing state switching between the ground state and the excited state can be achieved through introducing optical injection with a frequency (winj) close to the lasing frequency of excited state (wES). The injection power required for the state switching depends on the scanning route of injection power, i.e. there may exist state bistability for the injection power within a certain region. For forward scanning injection power, with the increase of frequency detuning (ΔΩ = winj – wES), the injection power required for the state switching shows a decreasing trend accompanied by slight fluctuations. However, for backward scanning injection power, the injection power required for the state switching exhibits obvious fluctuations with the increase of ΔΩ. The width of the hysteresis loop fluctuates with ΔΩ, and the fluctuation amplitude is increased with the increase of the injection current. Additionally, the influences of the inhomogeneous broadening factor and the electron escape rate on the bistability performances are analyzed.

Celem pracy jest przedstawienie możliwości wykorzystania nowej metody do analizy zmienności genetycznej organizmów, w tym organizmów o znaczeniu przemysłowym. Zaproponowana metoda działa na dwóch poziomach — na poziomie porównań aminokwasów oraz na poziomie porównań ich kodonów, tj. na poziomie kodu genetycznego. W pracy przedstawiono analizę inhibitorów proteinaz z nasion dyniowatych oraz analizę cytochromu c wybranych roślin uprawnych. Ponadto, za pomocą nowej metody dwupoziomowej analizy zmienności genetycznej otrzymano wyniki, które wykorzystano do interpretacji drzew filogenetycznych zbudowanych dla analizowanych sekwencji.
The aim of this study is to present the possibilities of using a new method for genetic variability analysis of organisms, including organisms of industrial use. The proposed method works at two levels — at the amino-acid comparison level and at the amino-acid codon comparison level, i.e. at the genetic code level. The paper presents analysis of proteinase inhibitors from squash seeds and analysis of cytochrome c of selected crops. Moreover, the results obtained using the new method of genetic variability two-level analysis, have been used to interpret the phylogenetic trees constructed for the analyzed sequences.

W artykule przedstawiono internetowy Atlas metod kartograficznych, skierowany do tych, którzy chcą poznać podstawowe zasady redagowania map statystycznych.

The free and all accessible Atlas of cartographic methods has been available on the Internet at www. educarto.pl since May 2012. The atlas was elaborated by the staff of the Department of Cartography of Warsaw University in 2010-2012. Growth of computer technologies has made it possible for everyone to author a map - especially a statistical one. Thus has appeared the need to prepare and make accessible to wider public a more elaborate guide than just a handbook or a set of instructions on how to run the program. The Atlas has been made to cater to the needs of those interested in learning basic rules of statistical map editing, so - of geography students, experts in spatial economy and environmental protection, surveyors. It is educational in character and aimed at showing quantitative methods and forms of cartographic presentation and focusing attention on map interpretation. It presents five quantitative forms and methods of presentation: diagram map, choropleth map, isoline map, dot map and quantitative symbols. The Atlas of cartographic methods is composed of two main parts (Fig. 1). The first part contains three 'chapters' of texts while the second - maps along with short commentaries. The first chapter is an elaboration entitled 'From the history of presentation forms and methods' and is illustrated with old maps. The second one - 'From data to map' - describes the process of editing a statistical map. It deals with data features and the possibilities of their transformation to fulfill the requirements of a specific presentation: - method of data reference (to points, area or line), data character (absolute, relative), method of showing data (continuous, discrete). The third chapter is entitled 'Methods step by step'. Its aim is to acquaint users with basic characteristics of the five forms of cartographic presentation. The second part of the atlas - 'Maps' - is a dynamic internet application and interactive environment for generating atlas full scale drawings. The application was programmed in PHP and is linked to MySQL database. The application's interface design was aimed to support the demonstrativeness of the Atlas - available functions have been limited to a minimum. The GUS (Central Statistical Office) Bank of Local Data resources (www.stat.gov.pl) served as material for elaborating maps in the Atlas. For elaborating a part of the Atlas full scale drawings an earlier prepared group of raster images was used. They were put on the server and shown in accordance with the parameters selected by the user. The remaining full scale drawings were created in a more complex way. Here applications programmed in PHP play an essential part. They process spatial and attribute data and display an automatically created map together with legend. The internet Atlas of cartographic methods can be treated as the first stage of a wider elaboration including all basic forms and methods of presentation.
