A cast iron is gradient material. This means that depending on the cooling rate it is possible, at the same chemical composition and the physicochemical state of molten metal, to obtain material with a different structure. The connection between the wall thickness of the casting and the speed of its cooling expresses the casting module. Along with the module escalation a cooling rate of the casting is reducing what can cause changes of the microstructure and the increased tendency to the crystallization of distorted graphite forms. Inspections of experimental castings from nodular cast iron with different modules were conducted to the graphite form.
Combining surface measurement data from individual measurements of surface fragments is an issue that has been recognized for flat surfaces. The connection takes place on the principle of making ‘overlap’ measurements according to a specific measurement strategy, and then the algorithm synthesizes the measurement data for the common part (data fusion). This paper presents a method of combining partial data into one larger set using image processing methods. The purpose of the analysis is to combine surface data of a more complex shape in terms of surface roughness and waviness. A successful attempt was made to combine surface measurement data located on a cylindrical surface – convex surface. A rotated table was designed and used for surface data acquisition. The datasets were acquired with the use of CCI 6000 (366 μm – 366 μm) with the assumed overlapping of at least 20%. The measurement datasets were first pre-processed: filling in non-measured points, levelling and form re- moving were applied. For such processed datasets, the common part was identified (data registration) and then the data fusion was performed. An example of stitching the surface datasets shows usefulness of the presented methodology.
Public spaces designed in a reasonable way make up an element that heals the city. They are both areas dedicated to collective recreation and a catalyst for social activities. Regarding a rational space exploitation, a reuse of grounds that are being liberated as a result of cities reorganization and revitalization of postindustrial areas should be a clue. The latter represent a unique esthetic virtues due to specificity of their original function. Comparison of the selected designs and scientific approaches had been made in order to take the floor in a debate about devastated areas revitalisation and city – and center-making capability of cultural investments. The importance of psychological links between human and his environment is set down by the presence of features defining the open form in a mentioned projects.
Over the past few decades in landscape architecture the new trend can be observed – putting artistic earthworks into public space. New ideas, whose roots date back to prehistoric times, have a close relationship with the artistic mainstream of land art. This paper is an attempt to determine the reasons for the use of expressive terrain as an essential factor in modern parks compositions, for example European and American facilities.
The method of determining the accuracy of polymer molds in plaster forms has been discussed. Distortion of the surface of molds and
plaster molds has been assessed. It has been found that the presence of monolithic and porous structure in the samples does not change the
accuracy of the surfaces when forms are prepared for removing the material of the model. It has been found that in case of full-mold
casting it is more expedient to form the mold cavity with cellular adjustable structures of molding prototypes.
This article is devoted to the official forms in the inflection of chosen toponyms in Poland and the variety of dialectal singular and plural place names. The variety of place names often diverges from the rules of language use, and causes language users problems. The toponyms have peculiar, locally used inflected forms; the outside-linguistic (non-linguistic) factors that are social and local factors, play an important role in the inflection of place names. The local population often uses other forms than those recommended by official sources. I focus my attention on the genitive forms of toponyms because it is mainly here that one can see clear variations in the official and local inflection of place names. The material shows that the singular masculine toponyms have genitive endings: -a (in the official variety), -u (in the local variety), for example Biłgoraj, gen. Biłgoraja, but in the local dialect: biłgoraju. The singular feminine place names have genitive endings: -ej (in the official variety), -y||-i (in the local variety): Brzezowa, gen. Brzezowej, but Brzezowy in the local dialect. The plural toponyms have genitive endings: -ø, -ów, -i (-y), but in the local circulation the ending -ów is dominant and demonstrates a wider expansion in use. For example Brzózki, gen. Brzózek, in the local variety Brzuskuf; Budy, official gen. Bud, but Buduf; Burnie, gen. Burni, in the local dialect: Burniuf. The gathered material reflects a hesitation in the inflection of toponyms, as the linguistic customs and presented dialectal records of forms of genit ives of place names show a significantly diverse approach towards the Polish language.
The author tries to explain what consequences for social morality ensue from the assumption that moral attitudes are expressed not only in words but also in reactive attitudes. P.F. Strawson assumes that acts of resentment can alter attitudes of those who have triggered them by their behavior. On the other hand, we are ready to control our outbursts of short temper and anger to a certain degree if we take into account agents’ motives and their limited ability to exercise self-control. Moreover, it seems that reactive attitudes – though less precise than verbal rebuke – are more frank and straightforward. Nevertheless, why must I, when I hear a mediocre academic researcher brag over and over again about his apparently essential contribution to philosophy, curb my moral assessment of his self-importance to the level of my irritation? Why should I feel constrained to keep my moral disgust in tune with my impatience mixed with amusement? Why shouldn’t I continue to believe that I can be an amiable character and a rigorous moral person at the same time?
Obtaining discrete data is inseparably connected with losing information on surface properties. In contact measurements, the ball tip functions as a mechanical-geometrical filter. In coordinate measurements the coordinates of the measurement points of a discrete distribution on the measured surface are obtained. Surface geometric deviations are represented by a set of local deviations, i.e. deviations of measurement points from the nominal surface (the CAD model), determined in a direction normal to this surface. The results of measurements depend both on the ball tip diameter and the grid size of measurement points. This article presents findings on the influence of the ball tip diameter and the grid size on coordinate measurement results along with the experimental results of measurement of a free-form milled surface, in order to determine its local geometric deviations. One section of the surface under research was measured using different measurement parameters. The whole surface was also scanned with different parameters, observing the rule of selecting the tip diameter d and the sampling interval T in the ratio of 2:1.
The paper discusses a method of quantitative comparison of cylindricity profiles measured with different strategies. The method is based on applying so-called Legendre-Fourier coefficients. The comparison is carried out by computing the correlation coefficient between the profiles. It is conducted by applying a normalized cross-correlation function and it requires approximation of cylindrical surfaces using the Legendre-Fourier method. As the example two sets of measurement data are employed: the first from the CMM and the second one from the traditional radial measuring instrument. The measuring data are compared by analyzing the values of selected cylindricity parameters and calculating the coefficient of correlation between profiles.
A meadow, a flowery meadow, a clearing, a lawn – smoothly trimmed, flat and recessed, a grassy pathway – these are elements of gardens that have been known for centuries, used in different styles and different types of gardens, including in public spaces. Pratum commune, commons or grassy mounds are the landmarks of the landscape of many a city, both currently and throughout history. Decorative grasses, such as pampas, Miscanthus or Pennisestum started to be used in garden compositions in XIX-century England. Initially more so due to their peculiarity than beauty. However, it was naturalism that gave rise to the wider use of grasses in gardens and parks in various places of the world and gained many propagators, including W. Robinson, J. Jensen K. Foerster and P. Oudolf.Grasses are currently often designed by landscape architects in urbanised spaces. They are employed both in geometric and freeform compositions. Their texture and delicate colour create a background for more expressive plants. They often constitute the key element of naturalist layouts, and the use of domestic species aids in preserving biodiversity and recreating the domestic landscape. Many of these current projects have been discussed in magazines and subject literature and have received awards in competitions. This review article is devoted to this subject.
There is estrimated more than 750 (public and privat) hospitals active In Poland. In spite that there is legal regulation concerning hospital projects, realization and equipment – permanent financial problems concerning a public health service, results in standards of hospitals, much worse then represented in hospitals in highly developed countries. A long – term practice of authors, concerning both, design and implementation of hospitals, let them to formulate a set of remarks about disfunction, influalcing growth of a danger, risks and mistakes in medical practice, also unexpected accidents.
Computer-aided tools help in shortening and eradicating numerous repetitive tasks that reduces the gap between digital model and actual product. Use of these tools assists in realizing free-form objects such as custom fit products as described by a stringent interaction with the human body. Development of such a model presents a challenging situation for reverse engineering (RE) which is not analogous with the requirement for generating simple geometric models. Hence, an alternating way of producing more accurate three-dimensional models is proposed. For creating accurate 3D models, point clouds are processed through filtering, segmentation, mesh smoothing and surface generation. These processes help in converting the initial unorganized point data into a 3D digital model and simultaneously influence the quality of model. This study provides an optimum balance for the best accuracy obtainable with maximum allowable deviation to lessen computer handling and processing time. A realistic non trivial case study of free-form prosthetic socket is considered. The accuracy obtained for the developed model is acceptable for the use in medical applications and FEM analysis.
The use of canticles in liturgical monody goes back to the early Middle Ages when the practice of canonical hours began to be used extensively. The canticles of the Gospel (Benedictus, Magnificat and Nunc dimittis) were successively incorpora- ted into the structure of the canonical hours and became in time the most important chants of the Liturgy of the Hours (Laudes, Vesperae, Completorium).
Some shorter canticles of the Old Testament books were also included in the Divine Office but it was only after the Second Vatican Council that shorter canticles of the New Testament books came into Vespers. They replaced the final (i.e. the third) psalm.
The designation „song" which was used to describe „canticle" in the Polish translation of the revised Liturgy of the Hours appeared to be highly controversial and inadequate. Thus, it was necessery to explain such definitions as: canticle, psalm, hymn, song. Based on the studies it is possible to definitely determine that a return to the original designation (canticle) is necessary and inevitable, in order to avoid confusion in terminology. Benedictus and Magnificat have received the primary thrust of poetic translations of canticles into Polish. In the latter case there are as many as five different Magnificat translations in Polish church song-books; only two versions of the Benedictus have been found. These canticles have a wide liturgical application; their use is not limited to the Divine Office alone.
They have been introduced into the Roman Catholic Order of Mass as the chants after Communion, or as the responsorial psalms, or as the verses sung before Gospel. Some of them have become independent processional chants for Mass, especially the ones intended for Lent. As far as the number of musical settings is concerned, it can be said that the Magnificat canticle seems to be highly favored. Nevertheless the melodies connected to other canticles, including the ones with the texts from „non-Gospel" biblical books, deserve attention as well. The melodies originated either in the Gregorian chant, or in the ecclesiastical songs, or in foreign sources, or, finally, in indigenous pieces of original compositions.
Thus, the repertoire of the New Testament canticles exhibits itself as a rich resource of new chants which have been included in the official liturgy in Poland since the Second Vatican Council. Clearly, further research is required in the aera.
This article focuses on an extremely urgent problem of today’s Christian dialogue with China, i.e. the culture (and politics) of the People’s Republic of China (PRC) and asks whether a Christian dialogue with China – which understand herself as an atheist and Communist state, which, however, is a country of many religious traditions, is possible, and if so in what form? What are its prospects and challenges?
The starting point of the article, after some historical remarks, is a kind of heterotopy of the dialogue in Chinese context, involving (III.1.) the historical and political context, then (III.2) its partners, and fnally (III.3) its forms and contents. in this framework, this article is (IV) refection on the challenges, opportunities and prospects of the Christian dialogue with Chinese culture. This refection is not taken here from the standpoint of theology, but is rather a phenomenological description of the status quo. At the end of the article (V) some statements of pope John Paul II with regard to the dialogue of Christianity with Chinese culture are quoted as a kind of summary.
The article states a great asymmetry of partners of the dialogue in China caused by the restrictive religious policy. There are some forms of dialogue which, however, are realized outside of the institutionalized Christianity, i.e. the Christian Churches. The Churches themselves, due to their historical background, are not very interested in or prepared for an inter-religious dialogue.
