Opis:
The presented work covers the problem of developing a method of extruded bread classification with the application of artificial neural networks. Extruded flat graham, corn, and rye breads differening in water activity were used. The breads were subjected to the compression test with simultaneous registration of acoustic signal. The amplitude-time records were analyzed both in time and frequency domains. Acoustic emission signal parameters: single energy, counts, amplitude, and duration acoustic emission were determined for the breads in four water activities: initial (0.362 for rye, 0.377 for corn, and 0.371 for graham bread), 0.432, 0.529, and 0.648. For classification and the clustering process, radial basis function, and self-organizing maps (Kohonen network) were used. Artificial neural networks were examined with respect to their ability to classify or to cluster samples according to the bread type, water activity value, and both of them. The best examination results were achieved by the radial basis function network in classification according to water activity (88%), while the self-organizing maps network yielded 81% during bread type clustering.

Opis:
The aim of the study was to determine the effect of reduced pressure on the osmotic dehydration of apples. Tests were performed under vacuum of 8 kPa, 67 kPa, 80 kPa and under the atmospheric pressure (100 kPa). The samples were dehydrated in a sucrose solution with a concentration of 30°Bx, 50°Bx and 70°Bx. It has been shown that the effect of low pressure application depends significantly to the concentration of the osmotic solution. It has been found that the overall weight change significantly depend on the concentration of the solution, and after 3 hours of dehydration at a pressure of 80 kPa at solutions of 30°Bx, 50°Bx and 70°Bx total weight loss increased by 65%, 12% and 25% respectively, when compared to samples dehydrated at atmospheric pressure. From the studied variants of reduced pressure, the pressure of 80 kPa seems to be the optimal one, as evidenced by the lowest values of weight gain to water loss ratios for apples dehydrated in solutions of 50°Bx and 70°Bx.
Celem pracy było określenie wpływu obniżonego ciśnienia na przebieg odwadniania osmotycznego jabłek. Badania przeprowadzono przy zastosowaniu ciśnień 8 kPa, 67 kPa, 80 kPa oraz ciśnienia atmosferycznego (100 kPa). Próbki odwadniane były w roztworach sacharozy o stężeniu 30ºBx, 50ºBx i 70ºBx. Wykazano, że przy ocenie obniżonego ciśnienia istotne znaczenie ma stężenie zastosowanego roztworu osmotycznego. Stwierdzono, że całkowite zmiany masy w sposób istotny zależały od stężenia roztworu i po 3 godzinach odwadniania pod ciśnieniem 80 kPa w roztworach 30ºBx, 50ºBx i 70ºBx ubytki te wzrosły odpowiednio o 65%, 12% i 25% w stosunku do prób odwadnianych w warunkach ciśnienia atmosferycznego. Z przebadanych wariantów zredukowanego ciśnienia, ciśnienie 80 kPa wydaje się być ciśnieniem optymalnym, o czym świadczą również najniższe wartości stosunku przyrostu masy do ubytku wody dla jabłek odwadnianych w roztworach 50ºBx i 70ºBx.

Opis:
The objective of the presented work was to examine the optical properties of selected bio-fuel waste. Three independent optical methods: UV-Vis spectroscopy, infrared spectroscopy and chromametric measurements were applied to establish the possible quality control test for the obtained substances. The following by-products were tested: distilled glycerine, technical glycerine and matter organic non glycerine fraction from rapeseed oil bio-fuel production. The results show that analysis of UV-Vis spectra can give rapid information about the purity of distilled glycerine, while no direct information can be obtained concerning the concentration and kind of impurities. Transmission mode is more useful as compared to absorption, concerning the detection abilities of average UV-Vis spectrometers. Infrared spectroscopy can be used as a complementary method for determining impurities/admixtures in samples. Measurements of chroma give the quickest data to compare the colour of biofuel by-products obtained by different producers. The condition is, however, that the products are received through the same or similar chemical processes. The other important factor is application of well defined measuring background. All the discussed analyses are quick, cheap and non-destructive, and can help to compare the quality of products.

Opis:
The paper presents data mining methods applied to gene selection for recognition of a particular type of prostate cancer on the basis of gene expression arrays. Several chosen methods of gene selection, including the Fisher method, correlation of gene with a class, application of the support vector machine and statistical hypotheses, are compared on the basis of clustering measures. The results of applying these individual selection methods are combined together to identify the most often selected genes forming the required pattern, best associated with the cancerous cases. This resulting pattern of selected gene lists is treated as the input data to the classifier, performing the task of the final recognition of the patterns. The numerical results of the recognition of prostate cancer from normal (reference) cases using the selected genes and the support vector machine confirm the good performance of the proposed gene selection approach.

Opis:
Two-dimensional numerical investigations of the fluid flow and heat transfer have been carried out for the laminar flow of the louvered fin-plate heat exchanger, designed to work as an air-source heat pump evaporator. The transferred heat and the pressure drop predicted by simulation have been compared with the corresponding experimental data taken from the literature. Two dimensional analyses of the louvered fins with varying geometry have been conducted. Simulations have been performed for different geometries with varying louver pitch, louver angle and different louver blade number. Constant inlet air temperature and varying velocity ranging from 2 to 8 m/s was assumed in the numerical experiments. The air-side performance is evaluated by calculating the temperature and the pressure drop ratio. Efficiency curves are obtained that can be used to select optimum louver geometry for the selected inlet parameters. A total of 363 different cases of various fin geometry for 7 different air velocities were investigated. The maximum heat transfer improvement interpreted in terms of the maximum efficiency has been obtained for the louver angle of 16° and the louver pitch of 1.35 mm. The presented results indicate that varying louver geometry might be a convenient way of enhancing performance of heat exchangers.

Opis:
Cryptographic hash functions are fundamental primitives in modern cryptography and have many security applications (data integrity checking, cryptographic protocols, digital signatures, pseudo random number generators etc.). At the same time novel hash functions are designed (for instance in the framework of the SHA-3 contest organized by the National Institute of Standards and Technology (NIST)), the cryptanalysts exhibit a set of statistical metrics (propagation criterion, frequency analysis etc.) able to assert the quality of new proposals. Also, rules to design "good" hash functions are now known and are followed in every reasonable proposal of a new hash scheme. This article investigates the ways to build on this experiment and those metrics to generate automatically compression functions by means of Evolutionary Algorithms (EAs). Such functions are at the heart of the construction of iterative hash schemes and it is therefore crucial for them to hold good properties. Actually, the idea to use nature-inspired heuristics for the design of such cryptographic primitives is not new: this approach has been successfully applied in several previous works, typically using the Genetic Programming (GP) heuristic [1]. Here, we exploit a hybrid meta-heuristic for the evolutionary process called Gene Expression Programming (GEP) [2] that appeared far more efficient computationally speaking compared to the GP paradigm used in the previous papers. In this context, the GEPHashSearch framework is presented. As it is still a work in progress, this article focuses on the design aspects of this framework (individuals definitions, fitness objectives etc.) rather than on complete implementation details and validation results. Note that we propose to tackle the generation of compression functions as a multi-objective optimization problem in order to identify the Pareto front i.e. the set of non-dominated functions over the four fitness criteria considered. If this goal is not yet reached, the first experimental results in a mono-objective context are promising and open the perspective of fruitful contributions to the cryptographic community.

Opis:
Stable and efficient nitrogen removal is one of main goals of wastewater treatment. Applying deammonification, beyond many advantages, results in the risk of the WWTP effluent quality violation in case of the failure of the process. Then nitrogen load to activated sludge is increasing rapidly which could therefore lead to quality violation in activated sludge effluent. Simulation studies have been presented on the effect of deammonification failure on nitrogen removal performance in the case of a typical, medium sized WWTP (ca. 115 000 PE). The studies were based on the calibrated ASMI model of real WWTP and a fictional scenario of implementing deammonification and subsequent failure. Implementing deammonification enables SR T optimization of the sludge retention time (SRT) in its main line thanks to lower nitrogen load. Two scenarios have been shown, considering or not optimization of the SRT in WWTP. The results show that SRT optimization leads to decrease in nitrifier mass and raises difficult issues in appropriate nitrogen concentration in the effluent.

Opis:
Nitrification is one of the fundamental biological processes in wastewater treatment and key element of nitrogen removal processes. It is not only used in traditional way of treatment with denitrification, but also in advanced processes for dewatering liquor side-stream treatment technologies. Like other biological processes, nitrification effectivity may be affected by number of factors such as amount of nitrifiers, substrate and oxygen availability and possible presence of inhibitors. According to these facts, only way to gain information about process dynamics is analytical nitrification rate test performance. Available guidelines focus on test conditions and analytical tools that should be used without any advice for number of results required to estimate accurate nitrification rate. High number of results needed in single nitrification rate test reflects in higher efforts and test costs. In this paper, over 100 nitrification rate tests results were analysed. Tests were performed in recent years on many wastewater treatment plants in Poland on activated sludge from different processes from main and side-stream treatment installations, where full or partial nitrification were used as a way of N-removal. Created database was used to define how big impact on overall nitrification rate has number and interval of results in performed test.
Nitryfikacja, jako jedna z podstawowych przemian azotu w przyrodzie, odgrywa również istotną rolę w technologii oczyszczania ścieków. Podobnie jak pozostałe procesy biochemiczne, istnieje szereg czynników mogących w sposób niekorzystny wpływać na jego przebieg. Jedną z metod monitoringu efektywności procesu jest wykonywanie testów szybkości nitryfikacji, polegających na monitoringu analitycznym wybranych form azot i określeniu ich zmienności w czasie. W celu określenia wpływu czasu trwania testu i częstotliwości wykonywania oznaczeń przeanalizowano wyniki ponad 100 testów szybkości nitryfikacji. Bazowe dane pochodziły z prac prowadzonych na rzeczywistych obiektach z tradycyjną nitryfikacją-denitryfikacją, jak również w układach do skróconej i częściowej nitryfikacji odcieków po odwadnianiu osadów.

This paper presents dynamic stability simulation tests of the Ł34 dynamic loader. The simulations were run according to military standards of United States of America. Tested loader had to overcome two obstacles at a first gear velocity. The first obstacle were pothole, while second one were rut. The current obstacles were crossed by Ł34 loader with two configurations. The first of them were loader in transport configuration, whereas second one were loader with maximum lift height of the bucket. The crossing of the rut was performed only by the loader in transport configuration, whereas passing of the pothole was performed by the loader in both configurations. The two obstacles also were crossed by loader with a nominal load and without it. This paper also defines effects of the modification of loader with more stiffer and more flexible tyres. There were also consider effects of the modification of Ł34 loader with integrated articulation.

Opis:
In result of searching in the Morasko preserve for the documentary series Meteorite Men two irons were found below ground. A 544-g shrapnel-like with weak shock deformations, mildly weathered, at low depth, and 34-kg individual, with its upper surface 156 cm deep, with a thick shell of clay and weathering minerals. Of particular interest is presence of chukanovite, a mineral discovered in the Dronino iron meteorite. Morasko is the second meteorite, where chukanovite could be found. The recovery of a new specimen so much deeper than the previous depth record, suggests that further, more detailed surveys should be conducted in the future with improved metal detecting equipment. Moreover, the larger specimen was found embedded in a Miocene clay, which demonstrates that it fell from the sky at that exact spot and was not deposited in glacial terminal moraine.
