Opis:
The fencing of the ceremonial courtyard in the Wilanów royal palace rarely attracted scholarly attention. However, a recent archaeological survey and archive inquiries brought to light new research material, which allows a more detailed description of the transformations of this part of the residence's spatial arrangement. The barrier, for the first time visible in the site plan of 1682, consisted of a row of pillars with spans filled with iron railings. After Elżbieta Sieniawska purchased the Wilanów estate, the space of the ceremonial courtyard was restricted by the construction of the palace's wings. The alterations may have included the courtyard's fence, as shown by the 17th- and 18th-century site plans and the discovery of the remains of two variants of its course during excavations. When the palace was owned by Maria Zofia and August Czartoryski and Izabela Lubomirska, the fence consisted of stone columns alternating with wooden ones; some of the pillars were later demolished or exchanged for stonework. In 1784, as a result of the construction of new pavilions at the southern wing, the fence lost its practical function and deteriorated. Destroyed during military operations in 1794, it was rebuilt almost entirely of wood. In 1801, Stanisław Kostka Potocki had both courtyards and the barrier dismantled and replaced with an oval lawn. Potocki sought to transform the setting of his residence according to the fashion of the day, that is, in the spirit of English designs he had seen during his travels and the Puławy estate with which he was familiar. His actions were intended to increase, not without an element of rivalry, the splendour of his family.

Opis:
A conceptual framework to design sustainable pension policy is offered to tackle the inter-plays between different determinants from the perspective of economic policy and the concept of sustainable development. The investigation of the main socio-economic determinants presented in the literature resulted in the designing of a holistic conceptual framework, which is designed to sup-port decision-makers and researchers who need to understand the determinants of specific policy programmes and their long-term socio-economic consequences. As a result, it helps to determine and design a sustainable pension policy. The sustainable framework emphasises the ideological back-ground for the economic debates, historical paths plotted in the path-dependence 4S framework and the key arguments for and against the funded and unfunded pension schemes. The sustainable con-ceptual framework emphasises the multiple objectives of pension policy, resource flows and the capi-tal formation debate in economics, as well as the global perspective of capital flows.
Zaproponowane są ramy koncepcyjne dla projektowania zrównoważonej polityki emerytalnej w celu rozwiązania problemu wzajemnych zależności pomiędzy różnymi determinantami z punktu widzenia polityki gospodarczej i koncepcji zrównoważonego rozwoju. Badanie głównych społeczno-ekonomicznych uwarunkowań przedstawionych w literaturze doprowadziło do opracowania całościowych ram koncepcyjnych, które mają wspierać decydentów i badaczy, którzy muszą zrozumieć determinanty określonych programów politycznych I ich długoterminowe społeczno-ekonomiczne konsekwencje. W rezultacie pomaga się określić I zaprojektować zrównoważoną politykę emerytalną. Zrównoważone ramy koncepcyjne kładą nacisk na ideologiczne tło debat gospodarczych, ścieżki historyczne ujęte w modelu 4s zależnej ścieżki oraz kluczowe argumenty za I przeciw kapitałowych I repartycyjnych systemów emerytalnych. Niniejsze ramy koncepcyjne wskazują na wiele celów polityki emerytalnej, przepływy zasobów i debaty o tworzeniu kapitału w ekonomii, a także globalną perspektywę przepływu kapitału.

Opis:
This article aims at giving a simplified presentation of a new adaptive semi-Lagrangian scheme for solving the (1 + 1)- dimensional Vlasov-Poisson system, which was developed in 2005 with Michel Mehrenberger and first described in (Campos Pinto and Mehrenberger, 2007). The main steps of the analysis are also given, which yield the first error estimate for an adaptive scheme in the context of the Vlasov equation. This article focuses on a key feature of our method, which is a new algorithm to transport multiscale meshes along a smooth flow, in a way that can be said optimal in the sense that it satisfies both accuracy and complexity estimates which are likely to lead to optimal convergence rates for the whole numerical scheme. From the regularity analysis of the numerical solution and how it gets transported by the numerical flow, it is shown that the accuracy of our scheme is monitored by a prescribed tolerance parameter \epsilon which represents the local interpolation error at each time step. As a consequence, the numerical solutions are proved to converge in L\infty towards the exact ones as \epsilon and \delta t tend to zero, and in addition to the numerical tests presented in (Campos Pinto and Mehrenberger, 2007), some complexity bounds are established which are likely to prove the optimality of the meshes.

Opis:
This paper deals with a finite difference method for a wide class of weakly coupled nonlinear second-order partial differential systems with initial condition and weakly coupled nonlinear implicit boundary conditions. One part of each system is of the parabolic type (degenerated parabolic equations) and the other of the elliptic type (equations with a parameter) in a cube in R1+n. A suitable finite difference scheme is constructed. It is proved that the scheme has a unique solution, and the numerical method is consistent, convergent and stable. The error estimate is given. Moreover, by the method, the differential problem has at most one classical solution. The proof is based on the Banach fixed-point theorem, the maximum principle for difference functional systems of the parabolic type and some new difference inequalities. It is a new technique of studying the mixed-type systems. Examples of physical applications and numerical experiments are presented.

Opis:
A strong multiple designated verifiers signature (SMDVS) enables a signer to convince a set of verifiers by generating one signature, of which the verification needs a private key of a verifier. After a brief survey of current SMDVS schemes, we find no schemes suitable to a broadcast propagation, where the simulation needs only one verifier's private key. Motivated by this discovery, we propose a broadcast SMDVS scheme. The new scheme is proven secure in the random oracle model.

Opis:
In the present paper, trigonometric B-spline DQM is applied to get the approximated solution of coupled 2D non-linear Burgers’ equation. This technique, named modified cubic trigonometric B-spline DQM, has been used to obtain accurate and effective numerical approximations of the above-mentioned partial differential equation. For checking the compatibility of results, different types of test examples are discussed. A comparison is done between 2L and L∞ error norms with the previous, present results and with the exact solution. The resultant set of ODEs has been solved by employing the SSP RK 43 method. It is observed that the obtained results are improved compared to the previous numerical results in the literature.

The probabilistic schemes with independence between the trials show different dispersion characteristics depending on the behaviour of the probabilities of the binary event in the trials. This work proposes a probabilistic scheme with uniform correlation structure that leads to different dispersion characteristics depending on the sign of the linear correlation. Finally, a hypothesis test is proposed to identify the type of the dispersion of the probabilistic scheme.

Opis:
The main results of this paper are theorems which provide a solution to the open problem posed by Tassa [1]. He considers a specific family Γv of hierarchical threshold access structures and shows that two extreme members Γ∧ and Γv of Γv are realized by secret sharing schemes which are ideal and perfect. The question posed by Tassa is whether the other members of Γv can be realized by ideal and perfect schemes as well. We show that the answer in general is negative. A precise definition of secret sharing scheme introduced by Brickell and Davenport in [2] combined with a connection between schemes and matroids are crucial tools used in this paper. Brickell and Davenport describe secret sharing scheme as a matrix M with n+1 columns, where n denotes the number of participants, and define ideality and perfectness as properties of the matrix M. The auxiliary theorems presented in this paper are interesting not only because of providing the solution of the problem. For example, they provide an upper bound on the number of rows of M if the scheme is perfect and ideal.

Landslide is a common geological disaster which causes huge losses to people’s properties and national economic development. How to prevent and control landslides has become an important issue. This article introduces the geological and geographical environment of the landslide body, analyzes the basic characteristics of the landslide, calculates the landslide stability based on the ultimate equilibrium theory-based transfer coefficient method, discusses the development trend of the landslide and comes up with corresponding control schemes by taking the landslide body of Black Bovine Cave Copper Ore Mining & Beneficiation Project as example. It is found that the control scheme - “anti-slide pile + retraining wall + baffle + anchor cable” can be used to effectively prevent and control the geological disaster according to calculation. The study results can provide a reference for landslide body control.

Opis:
Employee Suggestion Schemes have been used in organizations for a long time due to the fact that they enable fostering of creative ability of employees. However, they must be used effectively and in a sustainable manner to better the creativity and innovation capacity of organizations in order to improve competitive advantage. Therefore there is a need to understand the maturity of Employee Suggestion Schemes. This paper proposes a new, structured evaluation tool for assessing an organizational Employee Suggestion Scheme maturity. It suggests five building blocks: Leadership and Work Environment, System Capability, System Effectiveness, Organizational Encouragement and System Barriers, each of them characterized by several relevant indicators and an assessment/grading scale in order for an organization to be able to determine the maturity level of their Employee Suggestion Scheme as: Initial stage, Development stage or Advanced stage. Organizations should apply this tool to assess the maturity level of their Employee Suggestion Scheme and draw a roadmap for its improvements.
