Lossless Compression of High-frequency Intervals in Digital Audio : bachelor's thesisIvan Benc
, 2022, undergraduate thesis
Abstract: In this Thesis, an algorithm for lossless audio compression in a time domain is developed and implemented. The algorithm is designed to estimate the signal frequency based on the number of local extremes, and adapts the encoding to the estimated high or low- frequency intervals. As possible adaptations, fitting line segments, quadratic Bézier curves to the signal, and dictionary compression are examined. Residuals are encoded with delta encoding and compressed with binary adaptive sequential coding. The difference in the proportions of line segments and curves used in the high and low-frequency intervals have been detected, but this is not significant enough for this kind of interval discrimination to be meaningful in the current design of the algorithm.
Keywords: lossless audio compression, delta encoding, binary adaptive sequential coding, greedy method

Abstract: Developments and innovation in the areas of mobile information technology, digital media and social networks foster new reflections on computer-mediated communication research, especially in the field of self-presentation. In this context, the selfie as a self-portrait photo is interesting, because as a meaningful gesture, it actively and directly relates the content of the photo to the author of the picture. From the perspective of the selfie as an image and the impression it forms, in the first part of the research we explored the distinctive characteristics of selfie pictures; moreover, from the perspective of the potential reflection of a selfie image on the personality of its author, in the second part we related the characteristics of selfie pictures to various personality constructs (e.g., Big Five personality traits narcissism and femininity-masculinity). Important aspects of selfies especially in relation to gender include the tilt of the head, the side of the face exhibited, mood and head position, later related also to the context of the selfie picture. We found no significant relations between selfie cues and personality constructs. The face-ism index was related to entitlement, and selfie availability to neuroticism.
Keywords: psychology, selfies, self-presentations, social media, selfie coding, personality assessment

The language of appraisal in British advertisements : the construal of attitudinal judgementAgata Križan
, 2016, original scientific article
Abstract: The article explores the occurrence and frequency of use of attitudinal judgement in British advertisement texts. Judgement, as one of the main attitudinal categories in the discourse-semantic appraisal model (Martin and White 2005), is concerned with the evaluation of human character and behaviour. The article focuses on the judgement categories of capability and propriety, as the research described concludes that they are the most frequently occurring of the judgement categories. Some typical instances encoding capability and propriety are discussed in terms of explicit and implicit manifestation. The article demonstrates that capability and propriety often participate in attitudinal double-coding due to the brevity of advertising texts and the creativity of advertising language. Capability and propriety are strongly socially motivated: they impose values upon the potential consumer, and hence upon society, and through them create social roles for the participants in the advertising interaction.
Keywords: advertisements, interpersonal meaning, appraisal, judgement, capability, propriety, attitudinal double-coding
