Trompa interestelar : el color sonoro de la trompa en la "llamada interestelar" de O. Messiaen

Mi trabajo versa sobre la obra de O. Messiaen "Des Canyons aux etoiles" (De los cañones a las estrellas), y en particular de uno de los movimientos de la obra: "Appel Interestellaire" -N.VI- (Llamada Interestelar) -para trompa sola-. Se estructura en dos partes. La primera se centra en su contexto histórico -como, cuando y para quien fue compuesta-; análisis formal, armónico, melódico, rítmico; y aspectos estéticos. La segunda parte está vinculada con la interpretación de la obra. Se realiza un análisis para la interpretación -técnica de la trompa, efectos sonoros, timbres-; se hace una comparación entre la interpretación de 2 diferentes trompistas, y por último, aporto mi propuesta de interpretación. El trabajo se cierra con una conclusión, bibliografía, y un extracto con anexos (esquema, partitura y datos o imágenes de interés).

Color ad spectral image assessment using novel quality and fidelity techniques

The ongoing development of the digital media has brought a new set of challenges with it. As images containing more than three wavelength bands, often called spectral images, are becoming a more integral part of everyday life, problems in the quality of the RGB reproduction from the spectral images have turned into an important area of research. The notion of image quality is often thought to comprise two distinctive areas – image quality itself and image fidelity, both dealing with similar questions, image quality being the degree of excellence of the image, and image fidelity the measure of the match of the image under study to the original. In this thesis, both image fidelity and image quality are considered, with an emphasis on the influence of color and spectral image features on both. There are very few works dedicated to the quality and fidelity of spectral images. Several novel image fidelity measures were developed in this study, which include kernel similarity measures and 3D-SSIM (structural similarity index). The kernel measures incorporate the polynomial, Gaussian radial basis function (RBF) and sigmoid kernels. The 3D-SSIM is an extension of a traditional gray-scale SSIM measure developed to incorporate spectral data. The novel image quality model presented in this study is based on the assumption that the statistical parameters of the spectra of an image influence the overall appearance. The spectral image quality model comprises three parameters of quality: colorfulness, vividness and naturalness. The quality prediction is done by modeling the preference function expressed in JNDs (just noticeable difference). Both image fidelity measures and the image quality model have proven to be effective in the respective experiments.

Development of Color Difference Equations Matching to Human Vision System

Research on color difference evaluation has been active in recent thirty years. Several color difference formulas were developed for industrial applications. The aims of this thesis are to develop the color density which is denoted by comb g and to propose the color density based chromaticity difference formulas. Color density is derived from the discrimination ellipse parameters and color positions in the xy , xyY and CIELAB color spaces, and the color based chromaticity difference formulas are compared with the line element formulas and CIE 2000 color difference formulas. As a result of the thesis, color density represents the perceived color difference accurately, and it could be used to characterize a color by the attribute of perceived color difference from this color.

Preliminary data on Brazilian monofloral honey from the northeast region using FT-IR ATR spectroscopic, palynological, and color analysis

Fourier transform infrared attenuated total reflectance (FT-IR ATR) spectroscopy was used to determine 14 different measurands in northeast Brazilian honey samples. Nine different honey samples (six monofloral and three polyfloral) from 2009 obtained from the company CEARAPI underwent FT-IR ATR, palynological, color, and sensorial analysis to obtain preliminary results for these types of honey. The results showed that there are five monofloral, three bifloral, and one extrafloral honey, and also that mid-infrared spectrometry can be used as a screening method for the routine analysis of Brazilian honey, with the advantages of being rapid, nondestructive, and accurate.

Computational Evaluation of Print Unevenness According to Human Vision

Print quality and the printability of paper are very important attributes when modern printing applications are considered. In prints containing images, high print quality is a basic requirement. Tone unevenness and non uniform glossiness of printed products are the most disturbing factors influencing overall print quality. These defects are caused by non ideal interactions of paper, ink and printing devices in high speed printing processes. Since print quality is a perceptive characteristic, the measurement of unevenness according to human vision is a significant problem. In this thesis, the mottling phenomenon is studied. Mottling is a printing defect characterized by a spotty, non uniform appearance in solid printed areas. Print mottle is usually the result of uneven ink lay down or non uniform ink absorption across the paper surface, especially visible in mid tone imagery or areas of uniform color, such as solids and continuous tone screen builds. By using existing knowledge on visual perception and known methods to quantify print tone variation, a new method for print unevenness evaluation is introduced. The method is compared to previous results in the field and is supported by psychometric experiments. Pilot studies are made to estimate the effect of optical paper characteristics prior to printing, on the unevenness of the printed area after printing. Instrumental methods for print unevenness evaluation have been compared and the results of the comparison indicate that the proposed method produces better results in terms of visual evaluation correspondence. The method has been successfully implemented as ail industrial application and is proved to be a reliable substitute to visual expertise.

Generic and professional caring in a Chinese setting: an ethnopraphic study

The objective of the present study is to describe the cultural care practices, meanings, values and beliefs which form the basis of caring in a Chinese context. The research has its starting point in a caring science perspective and a qualitative research approach with interpretative ethnography as methodological guideline. The theoretical perspective is formed by elements of the theory of caritative caring, developed by Eriksson, and the theory of Culture Care Diversity and Universality, developed by Leininger. Previous research of suffering, culture and caring is described and also a presentation of actual transcultural nursing research as well as a presentation of the social structure dimensions of Chinese culture is included in the theoretical background. The empirical part includes patients and relatives, nurses and Hu Gongs as informants. The data collected are analysed based on Geertz’s idea of forming “thick descriptions” through examining the “what, how and why” of people’s actions. The findings show that the family has a prominent position in Chinese caring practices. The patient plays an unobtrusive role and a mutual dependence between the patient and the family members is evident. The professional nursing care is an extended act which includes the family in the caring relationship. The care practices of the Chinese nurse are characterized by great professional nursing skills. Suffering is described by the informants as being caused by disease, pain and social circumstances. “Social suffering” is described as worse than physical or mental suffering. Culturally competent and congruent care is a prerequisite for avoiding cultural pain, imposition and blindness when caring for the suffering human being. The findings of the present study necessitate a broadening in caring theory to include the family in the caring relationship. A further conclusion is that a broadening in our perception and understanding of culture would promote the delivery of culturally competent and congruent care. Suffering need to be seen as enclosed in cultural patterns of how it is expressed, interpreted, understood and relieved. Care and caring need to be seen as embedded in culture and the care practices values and beliefs have to be congruent with the cultural patterns where the care is provided.

A Technique for Digital Color Image Watermarking Using ICA

With the increase of use of digital media the need for the methods of multimedia protection becomes extremely important. The number of the solutions to the problem from encryption to watermarking is large and is growing every year. In this work digital image watermarking is considered, specifically a novel method of digital watermarking of color and spectral images. An overview of existing methods watermarking of color and grayscale images is given in the paper. Methods using independent component analysis (ICA) for detection and the ones using discrete wavelet transform (DWT) and discrete cosine transform (DCT) are considered in more detail. A novel method of watermarking proposed in this paper allows embedding of a color or spectral watermark image into color or spectral image consequently and successful extraction of the watermark out of the resultant watermarked image. A number of experiments have been performed on the quality of extraction depending on the parameters of the embedding procedure. Another set of experiments included the test of the robustness of the algorithm proposed. Three techniques have been chosen for that purpose: median filter, low-pass filter (LPF) and discrete cosine transform (DCT), which are a part of a widely known StirMark - Image Watermarking Robustness Test. The study shows that the proposed watermarking technique is fragile, i.e. watermark is altered by simple image processing operations. Moreover, we have found that the contents of the image to be watermarked do not affect the quality of the extraction. Mixing coefficients, that determine the amount of the key and watermark image in the result, should not exceed 1% of the original. The algorithm proposed has proven to be successful in the task of watermark embedding and extraction.

Color change and quality response of ‘lane late’ orange submitted to degreening process

This study aimed at evaluating the effects of ethylene on peel color and compositional changes in ‘Lane late’ orange stored under refrigerated and ambient conditions. Physiologically mature, but green-peeled, oranges were exposed to ethylene gas under room temperature and high relative humidity for 24 hours. Storage chamber was ventilated with fresh air after 12 hours to mitigate consequences derived from fruit respiration. Both nondestructive analysis, such as peel color (hue angle, chromaticity, and brightness) and weight loss, and destructive ones (soluble solids, titratable acidity, pH, soluble solids to acidity ratio, and puncture force) were performed upon harvest, after degreening, and every three days during eighteen days in storage. Experiment was carried out using an entirely randomized design with thirty replications for nondestructive and four replications for destructive analyses, in a split plot scheme. Exposure to ethylene ensured a golden yellow peel for both fruit stored under ambient and refrigerated conditions. High relative humidity, associated with low temperature prevented fruit from losing moisture. Fruit exposure to ethylene did not affect weight loss, soluble solids, titratable acidity, pH, soluble solids, acidity ratio, or puncture force.

Export Tire Entry to Chinese Market

After the economic reform, China has undergone fast economic growth, urbanization and adopted the western lifestyle. Global enterprises are investing in China and Finnish companies began to enter the Chinese market after the 1980s. Fast economic growth has downside effects like pollution and thus more cleantech solutions are needed. There are different kinds of entry modes that companies are using when entering the Chinese market. This thesis focuses on export tire entry mode. The purpose of this study is to examine cleantech companies’ opinions about the export tire operations. The background of this study is built by combining the written knowledge about the history of the Chinese industry and market entry modes. The empirical part of the study is a semi-structured, qualitative analysis of five case companies that are operating together in a particular export tire and represent the highest Finnish cleantech knowledge. The results of this study indicate that the export tire entry is an easy and cost effective way to enter new markets or market segment. Export tire is really dependent on the leader who in this particular case succeeded well.

Emotional intelligence and multicultural project leadership in Finnish-Chinese MNC context

The main goal of this thesis was to examine how the emotional intelligence skills and multicultural project leadership style of a project manager interrelate and affect the success of a project. The research methods used are literature review in theoretical part of the thesis and semi-structured interviews in empirical part of the thesis. This study is a single case study i.e. one case company was selected to be the secondary level of analysis. Within the case company, four project managers were selected as research units to form the primary level of analysis. Literature review formed the basis for the empirical research and the interview questions were derived from the literature. Findings from the interviews were mirrored against the literature review findings, based on which both conclusions and generalisations could be made. Thus, both deductive and inductive methods were utilised to get more complete picture about the research topic. In the first part of the literature review the general leadership theories and the project leadership terminology are introduced as a background for the concept of emotional intelligence and the integrated leadership model. Emotional intelligence and its interrelation to different leadership concepts are discussed during the literature review. Chinese cultural aspects affecting the way of making business, and the multicultural leadership styles of the Finnish project managers are introduced in the following part of the literature review. It was found that the most successfully used multicultural leadership styles in Finnish-Chinese context are synergistic and polycentric, and these require emotional intelligence skills. In the empirical part on this thesis the findings from the semi-structured interviews are introduced, discussed and analysed. Interviews were done in private meeting rooms, and they were recorded and transcripted to add reliability and validity. Although the sample was only four project managers, the results show that the sample is quite saturated as the responses to several questions followed the same pattern. It was found that Finnish project managers in the case company are democratic and take cultural differences into account in their project leadership. Both synergistic and polycentric leadership styles are used with Chinese team members. Emotional intelligence capabilities and the emphasis of those differ a bit depending on the interviewee. Though, the results show that EI skills and the multicultural project leadership style used in Chinese context are interrelated. The findings from the literature review and the empirical research in this thesis are similar. Though, there is need for further research as the sample was small, and this thesis is a single case study. It is recommendable to make a multi-company study with larger sample of project managers. Also multi-industry perspective is recommendable for further research.
