Icons on the Surface
No full textThe bachelor thesis Icons on the Surface deals with the film representations of the human body in medieval culture. The main aim of the work is not only to illuminate how real life and real body in the Middle Ages compares with what we have seen in the movies, but also to analyze what the various attitudes towards this topic tell us about comtemporary cinematography and culture. In addition to several particular film analyses working as a case studies, the author examines the key role of body in the process of film narration and a relationship between the body of the film, the body behind the camera and the body of the viewer. The thesis also deals with the problem of capturing history on the movie screen and investigates the impulses that may lead filmmakers to bring the past to the life. The author sees film representation of medieval body as a challenge to filmmakers. In her point of view the medieval body is the body filled with unique symbolic meanings, oscillating in existential amplitudes. Thus, in the film represetations of this body, the artist may invite their audience to experience images on the screen in their basic aesthetic and symbolic qualities

No full textResearch data for the study titled Intelligent Modelling of the Real Dynamic Viscosity of Rubber Blends Using Parallel Computing
No full textModelling the flow properties of rubber blends makes it possible to predict their rheological behaviour during the processing and production of rubber-based products. As the non-linear nature of such complex processes complicates the creation of exact analytical models, it is appropriate to use artificial intelligence tools in their modelling. The present study was implemented to develop a highly efficient artificial neural network model optimised using a novel training algorithm with fast parallel computing to predict the results of rheological tests of rubber blends performed under different conditions. A series of 120 real dynamic viscosity-time curves, acquired by a rubber process analyser for styrene-butadiene rubber blends with varying carbon black contents vulcanised at different temperatures, were analysed using a Generalised Regression Neural Network. The optimisation of the model was done by limiting the fitting error of the training dataset to a pre-specified value of less than 1%. All repeated calculations were done via the technique of parallel computing with the use of multiple computer cores, which significantly reduces the total computation time. An excellent agreement between the predicted and measured generalisation data with an error of less than 4.7% was found, confirming a high generalisation performance of the newly developed model.The detailed examination of the data used in the study titled "Intelligent Modelling of the Real Dynamic Viscosity of Rubber Blends Using Parallel Computing" is facilitated by the file START.m with the author's comments.

The articles of this issue of Tattva – Journal of Philosophy discuss several important philosophical problems, which are closely linked to ongoing debates about ethics, technology, and religion.
Abey Koshy’s paper “Deconstructive Turn of Ethics: Subversion of Self-Identity in Derrida and Levinas” argues that French philosopher Emmanuel Levinas gives an ethical turn to deconstructive philosophy, which was introduced by Jacques Derrida and offered an alternative way of reading texts. By applying the praxis of deconstruction to the ethical field Levinas subverts the traditional view of the human being as having a stable self-identity and serving as the unique reference point for its relation to the world, including the other person. The fundamental problem of this idea is that it negates the alterity of the other in a concrete ethical situation, thus reducing him or her to a variant of the self. By showing that the autonomous ‘I’ is a construction that needs to be deconstructed Levinas makes room for an alternative view of ethical responsibility, which guarantees a passage from the reals of the self to the that of otherness.
The second article, “Moore on Scepticism & Certainty”, by Anandasagar analyses George Edward Moore’s proof of the external world and his discussion with Descartes’ famous dream argument. Moore has weakened this argument by showing that it is inconsistent. The author then highlights Moore’s claim that empirical propositions are certain and offers a logical explanation of this claim. The central systematic focus of this paper is the confrontation between scepticism and common sense, and the author argues that Moore succeeds to refute scepticism on the basis of common sense. In Moore’s view, the task of philosophy is confined to analysing the propositions supplied by common sense, which does not include establishing the truth or falsity of these propositions.
The next article by Kopal, entitled “The Art in Artificial: Locating the Artist in Machines”, discusses the impact of artificial intelligence on art production, a question that has gained a lot of traction due to the rapid spread of ChatGPT and other AI systems. The author explores the ways and means by which AI is able to make art and sometimes even fares better in this than human-made art. This is because AI is better at deconceptualisation and dissimilar juxtaposition, resulting in more creative works of art, although the drawback of these characteristics is that AI may produce nonsensical and absurd outcomes. The author concludes that works of art, produced by AI, deserve appraisal and encouragement.
The fourth paper of this issue is written by James Sundar Aaron John Samuel, and is entitled “St. Paul’s discourse and dialogue with King Agrippa and Governor Festus as a model for contemporary inter-religious understanding and communication”. It starts with a detailed textual analysis of Saint Paul’s dialogues with two rulers of different religious backgrounds about the central truth claims of Christian faith (the life, death, and resurrection of Jesus). In these dialogues, Paul uses rhetoric to argue the reasonability of his claims, thereby applying three ingredients for persuasive communication: ethos, referring to his credibility as a speaker, pathos, appealing to the emotion of his dialogue partners, and logos, referring to the content and the logic of his argument. The author argues that Paul’s threefold rhetorical method to discuss the truth of Christian faith offers a model for peaceful inter-religious communication in our times.
The final article is by Kamalpreet Kaur, and is entitled “Indian Ethics: Essence, Theory and Practice”. The author uses the difference between ethics, which is intuitive and comes close to innate and inclusive values, and morals, which is rational and law-bound, to point out the specificity of the ethical tradition in India. The fact that this tradition relies more on folktales than on rational argument and thus is more pragmatic than principled shows its uniqueness. Dharma, which summarizes the Indian ethical tradition, constitutes the ethical laws of the universe, harmonizing moral life in a way similar to how the laws of nature regulate the physical world. This means that this kind of ethics, embedding the idea of universal justice, involves responsibility in its widest sense, responsibility for the whole cosmos, yet not in the form of any external compulsion. Therefore, the author argues, Indian ethics serves as a complement to Western rational morals.
On behalf of the editorial board, I wish you a lot of intellectual pleasure in reading the articles of this issue and hope that they may stimulate your philosophical thinking and discussions about vital questions concerning our relationship with the other, the importance of common sense for our knowledge of the outside world, the impact of new technical developments upon the arts, the relevance of rhetoric for interreligious dialogue, and the contribution of Indian ethical traditions to the development of a global ethics.

The measurement of near wall flows using pneumatic wedge probes.
Get PDFThe three hole, wedge-type pneumatic pressure probe represents a robust
traverse probe design which is widely used for total and static pressure and yaw angle
measurements in turbomachinery. However, unsteady flows are incorrectly averaged due
to pneumatic meaning errors in the pressure pipes. Wedge probes also fail to measure the
correct static pressure when operating in close proximity to a wall through which the
probe is inserted. Thirdly, the aerodynamic calibration obtained for a wedge-type probe
in a closed wind tunnel differs appreciably from that obtained in an open jet. If not
corrected, these errors will corrupt any calculation of turbomachinery blade row
performance.
In this investigation, the second and third effects described above have been
addressed. A factorial experiment was completed in which the influence of seven
variables on the wall proximity effect was quantified. Flow visualisation studies were
performed to understand the responsible flow mechanisms. Two regions of re-circulating
flow were identified in the probe wake, the structure of which depended on the probe
immersion. Similar re-circulatory flows were resolved from three-dimensional
computational fluid dynamics (CFD) calculations of the flow over a wedge probe. A link
between the probe wake re-circulations and flow over the wedge faces was established.
Based on this understanding of the flow structures, a model was developed from which
the wall proximity effect could be predicted for a given set of conditions.
Wedge probe calibrations were completed in a closed wind tunnel and in two
open jets. Discrepancies in the static pressure coefficient and yaw angle sensitivity results
were found. These were partially explained in terms of modifications to the probe wake
structure which occurred when the probes were calibrated in the open jet facilities.
Procedures for correcting the wall proximity effect and for avoiding the facility
dependence of wedge probe calibrations were developed from this understanding of the
flow mechanisms involved.
Based on the findings of this investigation, a novel wedge probe was designed to
minimise the wall proximity effect. This probe demonstrated a reduction in the wall
proximity effect, from 20% dynamic head with current designs, to 3% dynamic head at
flows typical of high speed turbomachinery
