In Spain doctoral studies underwent a major legal reform in 1998. The new legislation has brought together the criteria, norms, rules, and study certificates in universities throughout the country, both public and private. A brief description is presented here of the planning and structuring of doctoral programs, which have two clearly differentiated periods: teaching and research. At the end of the 2-year teaching program, the individual and personal phase of preparing one's doctoral thesis commences. However, despite efforts by the state to regulate these studies and to achieve greater efficiency, critical judgment is in order as to whether the envisioned aims are being achieved, namely, that students successfully complete their doctoral studies. After this analysis, we make proposals for the future aimed mainly at the individual period during which the thesis is written, a critical phase in obtaining the doctor's degree. Not enough attention has been given to this in the existing legislation.

Abstract:In this study we have attempted to classify the acceleration signal, while walking both at horizontal level, and upstairs and downstairs, using wavelet analysis. The acceleration signal close to the body’s center of gravity was measured while the subjects walked in a corridor and up and down a stairway. The data for four steps were analyzed and the Daubecies 3 wavelet transform was applied to the sequential data. The variables to be discriminated were the waveforms related to levels -4 and -5. The sum of the square values at each step was compared at levels -4 and -5. Downstairs walking could be discriminated from other types of walking, showing the largest value for level -5. Walking at horizontal level was compared with upstairs walking for level -4. It was possible to discriminate the continuous dynamic responses to walking by the wavelet transform.

The nonlinearity of the electric vehicle DC charging equipment and the complexity of the charging environment lead to the complex and changeable DC charging signal of the electric vehicle. It is urgent to study the distortion signal recognition method suitable for the electric vehicle DC charging. Focusing on the characteristics of fundamental and ripple in DC charging signal, the Kalman filter algorithm is used to establish the matrix model, and the state variable method is introduced into the filter algorithm to track the parameter state, and the amplitude and phase of the fundamental waves and each secondary ripple are identified; In view of the time-varying characteristics of the unsteady and abrupt signal in the DC charging signal, the stratification and threshold parameters of the wavelet transform are corrected, and a multi-resolution method is established to identify and separate the unsteady and abrupt signals. Identification method of DC charging distortion signal of electric vehicle based on Kalman/modified wavelet transform is used to decompose and identify the signal characteristics of the whole charging process. Experiment results demonstrate that the algorithm can accurately identify ripple, sudden change and unsteady wave during charging. It has higher signal to noise ratio and lower mean root mean square error.

This article investigates how the traditional attire and religious iconography of Cristóbal Balenciaga's (1895–1972) country of origin inspired his designs. The arguments presented here build on what has already been established on the subject, provide new data regarding the cultural context that informed the couturier's creative process (with which the Anglo-Saxon world is less familiar) and conclude by investigating the reasons and timing of his exploration of these fields. They suggest why this Spanish influence is present in his innovations in the 1950s and 1960s and go beyond clichéd interpretations of the ruffles of flamenco dress and bullfighters’ jackets. The findings derive from research for the author's doctoral thesis and her curatorial contribution to the exhibition Coal and Velvet. Balenciaga and Ortiz Echagüe. Views on the Popular Costume (Balenciaga Museum, Getaria, Spain, 7 October 2016–7 May 2017).
