Multicommutated Flow-Injection Analysis
Opis:
Modern analytical techniques are expected to fulfil high requirements in terms of both the quality of the obtained analytical results as well as caring for the environment. The methods should be developed in accordance with the rules of so-called Green Analytical Chemistry. Flow analysis techniques meet these assumptions. Their rapid development, especially in terms of instrumental solutions has been observed in recent years. Instrumental solutions employed in the flow analysis techniques allow for shortening the time of analyses, minimization of samples and reagents consumption as well as waste production, reduction of the costs of analyses and the risk of exposure of laboratory personnel on toxic substances. Their use, in many cases, has also a beneficial effect on improving the precision and accuracy of the analytical determinations. The article presents selected instrumental solutions used in various flow analysis techniques. Flow analysis techniques can be divided, inter alia, according to: the way of sample introduction into a flow system (continuous or intermittent sampling), the type of the liquid stream (segmented (with gas) or unsegmented flow) as well as the applied elements of instrumental system. In analytical practice, the techniques of flow injection analysis and sequential injection analysis are used most often. Due to constructional reasons, the use of systems containing valves of the type: Lab-on valve and various instrumental solutions of multicommutated techniques: multicommutated flow injection analysis, multi-syringe flow injection analysis and multi-pumping flow systems deserves special attention.

Opis:
Noise concerns in shock absorbers can be divided into two categories. The first is fluid flow noise, or “swish noise”, caused by the oil being forced through openings in the valves. The type and temperature of the oil, its velocity and the orifice geometry all have an effect on this. In addition, the structural design of the shock absorber shell may either reduce or amplify the noise. The second type of shock absorber noise is often described as regular operational noise or “chuckle noise”. It can be observed in vehicles during low-displacement, higher-frequency events, such as driving over a slightly rough road. This effect measurable as a force discontinuity into the vehicle and can come from a number of sources in the shock absorber, e.g. hydraulic transitions. It is often traceable to the valve discs closing and opening, but can also be caused by cavitation/aeration in the oil and air being pulled through the valves. The work on noise improvement reported in this paper has been started using conventional shock absorbers to be extended and will cover in the future variable damping shock systems as well. The paper gives an overview about the configurations of a typical valve system including three basic regimes of operation, which correspond to the amount of oil flowing through a valve cavity. The aim of this work was to propose a finite element fluid flow model, which can be used in order to reduce the velocity of fluid flow through a cavity of a shock absorber valve. High flow velocity can cause high-content frequency vibrations and, in turn, audible noise. The model will be used for initial screening of new valve concepts and on the other hand to improve the currently use ones.

Opis:
Research was conducted to analyze the flow of a fluid within mechanical heart valve - Medtronic Hall. Physical experiment and numerical modelling were performed. The aim of the research was to determine the difference between obtained experimental and numerical data. In the experiment a dependency between static flow rate within the valve and static inlet and outlet pressure in the valve duct was examined. Moreover a dependency between static flow rate and angular valve position was also determined. Experimental data was used to perform a numerical flow analysis. The obtained flow rate values and angular positions of the valve were set to a finite-volumes-method model in order to achieve model output pressure values identical or similar to the ones obtained from the experiment. The resulting pressure values from the experiment and numerical analyses proved to be of the same order of magnitude, varying only by up to 10%. However, as far as differential pressure is concerned, numerical results were out of the range of measurement resolution. It can be assumed that numerical flow analyses quite correctly predict the real phenomenon and in view of measurement inaccuracy of used sensors authors would suggest using more accurate ones and repeating measurements for future clarification.

Opis:
The impeller of an existing industrial pump (with both geometry and performance known) was analyzed and redesigned using an integrated, design/analysis, turbomachinery geometry modeling and flow simulation system. The purpose of the redesign was to achieve improved impeller performance (at the duty point). Fluid dynamics and geometry modeling parts of the design/analysis system were systematically applied: a) to analyse the existing impeller (impeller A), which was designed using conventional (routine in industry) hydraulic layout procedures, and b) to develop a new impeller (impeller B), using a coupled, multilevel 1D-Q3D-3D for the design and optimization. This paper discusses the features and advantages of the integrated design system, in which the coupled CAD/CFD approach is fully implemented. The analysis results are presented for impellers A and B, with the latter demonstrating a predicted increased efficiency and smaller size. Comparisons of the CFD results for both impellers reveal internal flow features that explain the improved impeller B performance levels.

Opis:
Currently the welding as a technological process is concerned with special processes, the results of which cannot be checked in a complete degree by subsequent control, test of production what finally causes uncertainty of work of welded constructions. The process of welding is related to the local change of the internal energy of welded system and that leads to the local change of state of material expressing by change of microstructure and mechanical properties. This phenomena decide on the assessment of susceptibility of materials under defined welding condition and estimate of the weldability. It is compound relation and the mechanical behaviour of welded joints is sensitive to the close coupling between modules: heat transfer, microstructure evolution an mechanical fields. Welding process in physical meaning it is jointed with three laws govern mass and heat flow the laws of conservation of: mass, momentum and energy. The knowledge of the run of thermo-dynamical process under welding indicates on the possibility of active modelling and control of welding process with use intensive and extensive parameters. As the weld metal cools in the temperature range 2300 to 1800°K, the dissolved oxygen and deoxidising elements in liquid steel react to form complex oxide inclusions of 0.1 to 1 žm size range. In the temperature range 1800 to 1600°K, solidification of liquid to . ferrite starts und envelops these oxide inclusions. After . ferrite transforms to austenite in the temperature range 1100 to 500°K, the austenite transforms to different ferrite morphologies such as ferrite: allotriomorphic, Widmanstättena, and acicular. The macro-mechanical heterogeneity of welded structures is one of their primary features. The heterogeneous nature of the weld joints is characterised by macroscopic dissimilarity in mechanical properties. Numerical weldability analysis is a new powerful research and development tool which is useful for metallurgistics technologist and design engineers. Saying strictly the numerical analysis of weldability comprises thermodynamic, thermomechanical and microstructural modelling of the welding process. The result of this analysis is material susceptibility (SU). The fracture resistance of welded joints is mainly characterised by normalised parameters: SU1 = KIth / KIC for cold cracking or in the exploitation condition by SU2 = ./.C or J/JC, SU1 . SU2. From above-mentioned equations result that does not exist one global parameter which defines the step of susceptibility SU of base materials has been also executed with use of SINTAP program.

Opis:
Functions and their relations can affect numerous properties and metrics of a functional program. To identify and represent the functions and their calling connections, software analysers commonly apply semantic function analysis, which derives the static call graph of the program, based on its source code. Function calls however may be dynamic and complex, making it difficult to statically identify the callee. Dynamic calls are determined just at run-time, static analysis therefore cannot be expected to fully identify every call. Nevertheless, by utilising the results of a properly performed data-flow analysis as well as taking ambiguous references into account, numerous dynamic calls are discoverable and representable. We consider cases where the identifiers of the callee are statically determined, but they flow into the call expression from a different program point, and also, we manage to handle function calls whose identifiers are not fully identifiable at compile-time. By utilizing the improved reference analysis, we extend the static call graph with various information about dynamic function calls. We investigate such a function call analysis in the programming language Erlang.

Opis:
Higher-order mutants are created by injecting two or more mutations into the original program, while first-order mutants are generated by seeding single faults in the original program. Mutant generation is a key stage of mutation testing which is computationally very expensive, especially in the case of higher-order mutants. Although many mutation testing techniques have been developed to construct the first-order mutants, a very small number of techniques have been presented to generate the higher-order mutants because of the exponential growth of the number of higher-order mutants, and the coupling effect between higher-order and first-order mutants. To overcome the exponential explosion in the number of higher-order mutants considered, this paper introduces a new technique for generating a reduced set of higher-order mutants. The proposed technique utilizes a data-flow analysis to decrease the number of mutation points through the program under test and consequently reduce the number of higher-order mutants. In this technique only positions of defs and uses are considered as locations to seed the mutation. The generated set of higher-order mutants consists of a reduced number of mutants, which reduces the costs of higher-order mutation testing. In addition, the proposed technique can generate the higher-order mutants directly without generating the first-order mutants or by combining two or more first-order mutants. A set of experiments are conducted to evaluate the effectiveness of the proposed technique. The results of the conducted experiments are presented and compared with the results of the related work. These results showed that the proposed technique is more effective than the earlier techniques in generating higher-order mutants without affecting the efficiency of mutation testing.

Opis:
The study deals with the application of multicommutation flow analysis for determination of Cr(III) concentration in environmental samples at a trace level. The detection method was based on the luminol-H2O2 chemiluminescence reaction in basic aqueous solution using Cr(III) ions as a catalyst. The experimental part of investigation focused on the optimization of equipment conditions, i.e. reagent flow rate, injected sample volume and the work of solenoid valves. The specificity of the method was tested with respect to selected heavy metal ions. The presented method allowed determination of Cr(III) over the range from 2.5 to 50ng*cm-3, with a low detection limit (under optimum conditions: 0.15ng*cm-3). Multicommutation is one of the best methods of analytical procedure automation. The main advantages of multicommutation method, compared with classical flow injection analysis (FIA), is the ability to achieve more repeatable analytical signal, which in turn allows to improve the method precision (relative standard deviation, RSD, was 1.8% for 10 determinations of 20ng*cm-3 Cr(III)). Moreover, it is excellent from the point of view of environmental protection because it offers very low reagent consumption: luminol 0.26; H2O2 2.16; sample 0.15 (cm3 per peak). The sampling rate was about 90 samples*h-1.

Most of them (first of all, plastic and metal) can be easily recovered. The content of chemical elements in the components of the electronic devices was determined by X-ray fluorescence analysis. Taking into account the mass of electronic waste generated in Ukraine, the resource potential of metals was estimated. Most of metals are concentrated in mobile phones and monitors (about 2000 tons/year). Apart from common metals, silver, molybdenum, vanadium, rubidium, zirconium, antimony, yttrium, rhodium, bismuth, and gallium were also found.

The process of welding has dynamic character and is related with the local change of the internal energy E of welded system and can be defined by general dependence between intensive .j and extensive .j parameters. The knowledge of the run of thermo-dynamical process under welding indicates on the possibility of active modelling of weldability and the control of welding process: .j = .E/..j. Hence, these process can be enhanced by mathematical modelling and numerical analysis of weldability models of, i.e. welding processes of material behaviour in welding and the strength of welded structures. The main attention is focused on the assessment of susceptibility of materials under defined welding conditions using fracture mechanics parameters. The analysis is based on the normalised parameters such as: ./.c, KIth/KIC, as a measure of the susceptibility of materials in welding process. The deformation process and fracture parameters calibrations are influenced by constraint; hence the importance of determining the deformation behaviour and fracture parameters as a function of constraint. Furthermore, there established analytically the condition of welding process in mismatched weld joints for strength equal to base metal. Finally, same analytical examples which present new capabilities of weldability estimates and mechanical properties of mismatched weld joints are presented.

One possible method of drinking water treatment is chlorine dioxide disinfection. This technology, however, requires reliable control of its byproducts, including chlorite ions., which pose a threat to human health. In this paper an original procedure for flow indirect determination of chlorite in drinking water was described. This method relies on oxidization of chlorite ions by iron(III) in acid environment measurement of the spectrophotometric signal for the phenanthroline/iron(II) complex. The determinations were carried out by flow analysis with the use of a dedicated set of flow instruments. The method was used for analysis of natural samples collected from various water intakes in Kraków. The new analytic approach was compared with the routinely applied ion chromatography method.
Jednym ze sposobów uzdatniania wody pitnej jest jej dezynfekcja tlenkiem chloru(IV). Ważnym zadaniem, jakie wiąże się jednak z tym procesem, jest wiarygodna kontrola zawartości produktów ubocznych w postaci jonów chloranowych(III), stanowiących duże zagrożenie dla zdrowia człowieka. W pracy opisano oryginalną procedurę pośredniego oznaczania chloranów(III) w wodach. Polega ona na wykorzystaniu reakcji chloranów(III) z jonami żelaza(II) w środowisku lekko kwaśnym i pomiarze spektrofotometrycznego sygnału dla jonów żelaza(II) w obecności 1,10-fenantroliny. Oznaczenia wykonywano techniką przepływową z użyciem dedykowanego zestawu instrumentalnego. Metodę zastosowano do analizy próbek pobranych z różnych ujęć wody pitnej w Krakowie. Dokonano porównania opracowanego podejścia analitycznego z rutynowo stosowaną metodą chromatografii jonowej.
