Opis:
For over 10 years now in the literature on the subject of law and in relevant publications there have been allegations concerning the quality of the enacted law in Poland. This paper is an attempt to analyze both appearing demands to rationalize the process of making law as well as those concerning the creating of the catalogue of the biggest problems in this area. The Polish Constitution of 1997 defined in detail the system of the sources of law in its separate Chapter three, which is not common in the European constitutionalism. It took place when Poland was preparing for the accession to the European Union, whose system of the sources of law significantly differs from the classical, “normative” concept of the sources of law adopted in the Polish Constitution. The concept of making law accepted in the Polish Constitution seems to not fully correspond to the duties regarding EU notification of the changes in the Polish legal regulations. It affects the legislation act itself as well as the procedure of its enacting. It particularly influences the actual restriction of the Senate legislative competences, giving it only 30 days for reviewing a given act. The paper states that the regulation of Chapter three of the Constitution supplemented by the Constitutional Tribunal rulings based on the analysis of Art. 2 of the Constitution make an effective limit for the activities undertaken by the legislator which are inconsistent with the Constitution. The paper also analyses the practice of application of the rules concerning the legislative process comprised in Chapter four of the Constitution. Finally, the conclusion is drawn that to reach good legislative results it is not enough only to properly regulate all the legislative stages, but also to regulate the political system itself.

Opis:
The paper discusses quality of service in LTE and LTE-A networks seen as a challenge that can be met with Self-Organizing Networks (SON) functionalities. The SON concepts have been included in the LTE (E-UTRAN) standards since the first release of the LTE technology. Self-optimization functionalities will monitor and analyze performance measurements, notifications, and self-test results and will automatically trigger re-configuration actions on the affected network nodes when necessary. The SON specifications have been built over the existing 3GPP network management architecture, the ultimate implementation of SON in 4G networks will bring many advantages. Successive SON procedures are waiting for their time and money to be implemented in 4G, though some essential issues for example of inter Radio Access Technology (RAT) interfaces must be overworked.

Opis:
This paper is devoted to the total tardiness minimization scheduling problem, where the efficiency of a processor increases due to its learning. Such problems model real-life settings that occur in the presence of a human learning (industry, manufacturing, management) and in some computer systems. However, the increasing growth of significant achievements in the field of artificial intelligence and machine learning is a premise that the human-like learning will be present in mechanized industrial processes that are controlled or performed by machines as well as in the greater number of multi-agent computer systems. Therefore, the optimization algorithms dedicated in this paper for scheduling problems with learning are not only the answer for present day scheduling problems (where human plays important role), but they are also a step forward to the improvement of self-learning and adapting systems that undeniably will occur in a new future. To solve the analysed problem, we propose parallel computation approaches that are based on NEH, tabu search and simulated annealing algorithms. The numerical analysis confirm high accuracy of these methods and show that the presented approaches significantly decrease running times of simulated annealing and tabu search and also reduce the running times of NEH.

Opis:
Unlike in other ship types, the container ships cannot offer their services without containers and the shipping space become ineffective. Therefore, containers and slots are complimentary and indispensable service component in liner container shipping. The virtual container yard (VCY) is a modern concept and an effective CIM solution that underpins the collaboration between carriers. Carriers already have common platforms to interchange slots thus it is just one fine step away from implementing the similar strategy for containers. It is, through these findings, expected to change the carriers’ myopic view about the container interchange. The actual container statistics in Sri Lanka was extracted from the industry as the source of input for the study. The paper reveals that the VCY could reduce the inventory management cost by 19 percent. Carriers opted to interchange the container slots in cellular ships more than three decades ago. This paved the way for strong collaboration between carriers and provided many financial advantages. It helped in securing economic advantages through scale of economies in highly completive shipping industry. This paper provides empirical evidences of the financial savings of container interchange under different container sizes and types.

Opis:
Nowadays acoustic emission (AE) method is used in many fields of science, including in the diagnosis of machining processes such as turning, grinding, milling, etc. Determining of turning parameters has a great impact on the quality of the surface. This is especially important during finishing treatment. In the study of acoustic emission, method was used to optimize the cutting depth. Optimization was to determine the depth of cut, at which the vibration level exceeds the set level. The research was carried out on a universal CDS 6250 BX-1000 lathe centre using dynamometer DKM 2010 where assembled removable insert CCMT 09 T304 PF. Lathing process was performed on the shaft of 40 mm in diameter made of S235JR steel. The research was carried out at constant cutting speed v = 145 m/min and at constant feed f = 0.114 mm/rev. In the research was used a set of acoustic emission Vallen System. The kit includes: 4 channel signal recorder AMSY 6, two measurement modules ASIP-2/S, preamplifier with a frequency range 20 kHz – 1 MHz and the strengthening of 34 dB and AE signal measurement sensor type VS 150M, with a frequency range 100 – 450 kHz. During the study, the acoustic emission (AE) generated during the lathing process was recorded parameters: amplitude, number of events – hits, the effective value of the signal (RMS). Analysis of the research results allowed to determine the maximum depth of cut, at which the vibration does not reach the set limit value. The study can be the basis for the use of acoustic emission method to determine the parameters of the finishing lathing for obtaining a high quality surface.

Opis:
W celu optymalizacji procesu rewitalizacji złoża wykonuje się otworowe pomiary geofizyczne. Pozwalają one na identyfikację pozostałych w złożu węglowodorów i monitorowanie procesu sczerpywania złoża. Pomiary takie wykonuje się zarówno w otworach zarurowanych jak i niezarurowanych. Zastosowanie tych metod zilustrowane zostało na przykładach projektów rewitalizacji złóż. W otworze zarurowanym stosowane są głównie profilowania neutronowe. Impulsowe profilowanie neutronowe wykorzystuje się do określania kontaktu ropa-gaz i ropa-woda, natomiast profilowanie neutron-gamma umożliwia bezpośredni pomiar zawartości węglowodorów (poprzez wyznaczenie stosunku węgla do tlenu) oraz określenie litologii. W celu zwiększenia zasięgu radialnego, w stosunku do pomiarów neutronowych, stosowane jest również stacjonarne profilowanie oporności w otworze zarurowanym. W otworze niezarurowanym, dla celów rewitalizacji złoża, wykonywane są m.in. profilowania indukcyjne. Na podstawie tych pomiarów można uzyskać informację o wpływie filtracji na formację skalną a także przewidzieć reakcję złoża na zmianę przepływu wody. Dużym krokiem, w kierunku zmniejszenia ryzyka procesu rewitalizacji, stało się wykorzystanie aparatury do stałego monitorowania złoża, która dostarcza informacji o zmianie parametrów w czasie rzeczywistym. Metoda ta ma znacznie większy zasięg radialny w porównaniu z pomiarami aparaturą zapuszczaną do otworu
Well-bore measurements can contribute to risk management of revitalization by identifying and monitoring the drainage of remaining hydrocarbons. These measurements can be carried out both cased-hole and open-hole. Applications of these technologies are illustrated through case histories of revitalization projects. In cased-hole have been employed traditionally neutron logging tools. The pulsed-neutron capture measurement is mainly used to determine producing gas-oil and oil-water contact. Measurement of the gamma ray spectra, produced by both inelastic and capture of thermal neutrons, can be used to determine reservoir saturation (from C/O ratio) and lithology evaluation. In order to increase depth of investigation a new tool has been used that makes stationary measurements of resistivity through-casing. In open-hole can be used an array induction tool. Processing of array induction data provides information about a drilling mud invasion of the formation and can yield prediction of the expected field respond to water flooding

The practical training in the air is performed according to the parallelism of the training, which describes the technological relationships between the individual exercises. The purpose of this contribution is to propose a mathematical model which would enable the selection of exercises for each pilot, the appropriate selection of the aircraft and the moment of beginning of each exercise, so that all required exercises are carried out in the shortest possible time. Additionally, in this paper the concept of pilot’s habits and skills improvements is presented.

Opis:
In recent years the progress in algorithms optimization has resulted in many solutions in the area of fully automatic reconstructing of 3D model of any object from a sequence of non-metric images. An important step in the formation of a 3D model is so-called matching process of homologous points in the sequence of images. This stage is still a bottleneck for the reconstruction of objects consisting of uniform surfaces, such as sculptures, reliefs, or even the human body. The solution may be to apply an artificial variety to surfaces by covering them with a random texture pattern. A wide range of multimedia projectors, with increasingly higher resolutions and luminosities, enables us to perform the projection of any texture on the object, and then to register it. In this article, we present the idea of creating an artificial pattern, a structure that will provide significant improvement of automatic point identification stage, and the proper mapping of homologous points in the sequence of images. While creating a pattern allowing easy feature extraction does not present much of a problem, assurance of its uniqueness for the whole object for matching purposes, requires a deliberate idea. Statistical formulation of the problem demonstrates the high efficiency of the method.

Optimization of product in enzyme kinetics is successful by the showers of mathematical analysis with control measures. Enzymes are an important functional aspects of all biochemical processes, as they catalyze numerous reaction taking place within living organisms. With this view, optimization and quantification of product is stressed upon and in such a context, optimal control approaches have been applied in our study. In this article, we have formulated a mathematical model of enzymatic system Dynamics with control measures with a view to optimize the product as well as process conditions. Here, Pontryagin Minimum Principle is used for determination of optimal control with the help of Hamiltonian. We discuss the relevant numerical solutions for the concentration of substrate, enzyme, complex and product with respect to a specified time interval by varying control factors.

Opis:
In this article, we propose two model free control schemes that are based on pulse height modulation using low frequencies with the goal to compensate normal friction effects in drive trains that negatively influence the performance of e.g. a standard PID controller. The first control scheme uses pulse height modulation to especially compensate stick slip effects but increases vibration and noise in the drive train. To reduce such side effects a modified phase shifed pulse height control scheme based on multiple actuated joints is introduced. Both control schemes are compared with a standard linear controller as reference and evaluated by using six quality criteria.

The conducted tests were aimed at determination of the drop diameters and shaping of the velocity field at different configurations of the test injector. The test results allowed defining the relationship between the injector configuration and the distribution of velocities and dimensions of drops in the fuel stream. The effect of the fuel viscosity and injection pressure on the dimensions of fuel drop diameters and the distribution of the velocity field of drops in the stream were tested. The tests were carried out on a special test rig with a fixed volume chamber. The measurements were carried out with the use of laser Doppler measurement systems (PDPA, LDV). The tests were conducted for seven different fuel types varying in viscosity and surface tension. In addition, the injection pressure from 50 MPa to 130 MPa was applied. The test results allowed determining the relationship between the injector structure configuration, fuel types and fuel additives, and the distribution of velocity and an atomisation spectrum of drops in the fuel stream, and the air impact on the fuel stream.
