Fuzzy c-means clustering is a popular image segmentation technique, in which a single pixel belongs to multiple clusters, with varying degree of membership. The main drawback of this method is it sensitive to noise. This method can be improved by incorporating multiresolution stationary wavelet analysis. In this paper we develop a robust image segmentation method using Fuzzy c-means clustering and wavelet transform. The experimental result shows that the proposed method is more accurate than the Fuzzy c-means clustering.

The introductory chapter discusses the popular image of the ‘Romantic mad poet’ in television, film, theatre, fiction, the history of literary criticism, and the intellectual history of the twentieth century and its countercultures, including anti-psychiatry and psychoanalysis. Existing literary-historical work on related topics is assessed, before the introduction goes on to suggest why some problems or difficulties in writing about this subject might be productive for further cultural history. The introduction also considers at length the legacy of Michel Foucault’s Folie et Déraison (1961), and the continued viability of Foucauldian methods and concepts for examining literary-cultural representations of madness after the half-century of critiques and controversies following that book’s publication. Methodological discussion both draws on and critiques the models of historical sociology used by George Becker and Sander L. Gilman to discuss genius, madness, deviance, and stereotype in the nineteenth century. A note on terminology concludes the introduction.

AbstractEuropean Bronze and Iron Age vitrified hillforts have been known since the 1700s, but archaeological interpretations regarding their function and use are still debated. We carried out a series of experiments to constrain conditions that led to the vitrification of the inner wall rocks in the hillfort at Broborg, Sweden. Potential source rocks were collected locally and heat treated in the laboratory, varying maximum temperature, cooling rate, and starting particle size. Crystalline and amorphous phases were quantified using X-ray diffraction both in situ, during heating and cooling, and ex situ, after heating and quenching. Textures, phases, and glass compositions obtained were compared with those for rock samples from the vitrified part of the wall, as well as with equilibrium crystallization calculations. ‘Dark glass’ and its associated minerals formed from amphibolite or dolerite rocks melted at 1000–1200 °C under reducing atmosphere then slow cooled. ‘Clear glass’ formed from non-equilibrium partial melting of feldspar in granitoid rocks. This study aids archaeological forensic investigation of vitrified hillforts and interpretation of source rock material by mapping mineralogical changes and glass production under various heating conditions.

AbstractPliny the Elder testifies that roman workshops used volcanic glass (obsidian), but also produced and used a dark glass (obsidian-like glass) quite similar to the natural one. In the context of the study on medieval mosaics, the use of the obsidian and obsidian-like tesserae is a challenging research topic. In this paper, we present the results of a multidisciplinary study carried out on the Dedication wall mosaic, realized by a byzantine workshop in the 12th century in the Church of St. Mary of the Admiral in Palermo, and where numerous black-appearing tesserae, supposed to be composed of obsidian by naked-eyes observation, are present. Historical documents, multispectral imaging of the wall mosaic, and some analytical methods (SEM-EDS and XRPD) applied to a sample of black tesserae, concur in identifying here the presence of obsidian and different obsidian-like glass tesserae. This evidence, although related to the apparent tampering and restoration, could open a new scenario in the use of obsidian and obsidian-like glass tesserae during the Byzantine period in Sicily and in the reconstruction of multiple restoration phases carried out between 12th and 20th century AD on the mosaics of St. Mary of the Admiral.

By most assessments, Jimmy Carter's presidency was a failure. The popular image of Carter is that of a president who was politically naive, an inept manager, a well-meaning but nettlesome scold, and an unsuccessful leader. According to two recent scholarly evaluations, Carter was an ineffective leader who ranks in the bottom quintile of the thirty-nine presidents who have preceded George Bush.

The popular image of activism in the university involves students and academics campaigning for social justice and resisting the neo-liberalisation of the university. Yet activism has been subtly corporatised through the migration of corporate social responsibility from the private sector into the university, a trend that may be illustrated by reference to the growing influence of research ‘grand challenges’ (GCs). Attracting both government and philanthro-capitalist funding, GCs adopt a socio-political stance based on justice globalism and represent a responsibilisation of academic research interests. Compliance with the rhetoric of GCs and the virtues of inter-disciplinarity have become an article of faith for academics compelled to meet the expectations of research-intensive universities in chasing the prestige and resources associated with large grant capture. The responsibilisation of the efforts of researchers, via GCs, erodes academic ownership of the research agenda and weakens the purpose of the university as an independent think tank: the essence of the Humboldtian ideal. The conceit of corporate activism is that in seeking to solve the world’s problems, the university will inevitably create new ones. Instead, as Flexner argued, it is only by preserving the independence and positive ‘irresponsibility’ of researchers that universities can best serve the world.

Multilevel thresholding is a popular image segmentation technique. However, computational complexity of multilevel thresholding increases very rapidly with increasing number of thresholds. Metaheuristic algorithms are applied to reduce computational complexity of multilevel thresholding. A new method of multilevel thresholding based on Moth-Flame Optimization (MFO) algorithm is proposed in this paper. The goodness of the thresholds is evaluated using Kapur's entropy or Otsu's between class variance function. The proposed method is tested on a set of benchmark test images and the performance is compared with PSO (Particle Swarm Optimization) and BFO (Bacterial Foraging Optimization) based methods. The results are analyzed objectively using the fitness function and the Peak Signal to Noise Ratio (PSNR) values. It is found that MFO based multilevel thresholding method performs better than the PSO and BFO based methods.

Dispersive Power

Notwithstanding the pains which astronomers have taken to determine accurately the refraction of mixed light, nothing, I believe, has ever been done towards ascertaining the dispersive power of common air, or comparative degree of refrangibility of the differently coloured rays in their passage through our atmosphere. The importance of such an inquiry, however, must be obvious to every one who duly considers the effect which the different degrees of refrangibility of the variously coloured lights must necessarily produce in the apparent situations of differently coloured objects. Stars of different colours must be differently refracted, and the apparent altitude of the sun must vary according to the colour of the dark glass through which he is viewed.

Conspirators in the Polish Blue Police and Polish Criminal Police in Kraków during 1939‒1945 The article describes the history of Polish pre-war policemen who were forced to continue their service in the Polish Police in the General Government (the so-called Blue Police), created by German occupying authorities. Many of these policemen, faithful to the oath they had made before the war, worked for the Polish Underground State. In Kraków, the capital of the General Government, in the Autumn of 1939, Polish policemen began to create conspiracy structures, which gradually became one of the most effective Polish intelligence networks. Thanks to them, the Home Army, subordinated to the Polish Government-in-exile in London, could learn the secrets of the Kraków Gestapo and the German police. Despite the enormous efforts of the German counter-intelligence machine and the losses among the conspirators, they worked out the exact structure of the German forces in Kraków, helped the persecuted population and infiltrated secret German institutions. In post-war Poland, many of them experienced persecution at the hands of the communist regime. Most of them preferred to keep their wartime experiences secret. To this day their activities are poorly known, being suppressed by the popular image of a Polish policeman-collaborator created by the media.
