Hierarchical Identification of Large-Scale System Models

Jankovic, Boris R. January 1997 (has links)
Dissertation submitted in compliance with the requirements for the Doctor's Degree in Technology in the Department of Electrical Engineering (Light Current) at Technikon Natal / In this study we propose a new concept and methodology of hierarchical identification. The need for such a methodology comes from the fact that identification of large-scale systems (LSSs) by one-shot approach may be numerically very complex. The analysis of LSSs is, in general, not approached by the one-shot methodologies normally associated with non-LSSs. The proposed method of hierarchical identification can be therefore viewed as an extension of LSS methodologies to system identification. LSS methodology aims at breaking up the initial, complex problem into a set of smaller size subproblems. / D

O prontuário odontológico é um documento de grande importância na odontologia e, quando bem elaborado torna-se um grande aliado do Cirurgião-Dentista, satisfazendo as funções clínicas, administrativas e legais do mesmo. Sabe-se que são peça fundamental em casos de identificação humana, principalmente em casos onde há grande destruição dos corpos encontrados (carbonização, putrefeitos, entre outros). O presente estudo em vista a estes fatos buscou determinar por meio de questionários junto a 400 Cirurgiões-Dentistas de Cuiabá-MT, o grau de conhecimento dos mesmos sobre a importância do prontuário nos processos de identificação humana. Verificou-se que o Cirurgião-Dentista de Cuiabá-MT apresenta conhecimento satisfatório sobre elaboração, manutenção e importância dos dados (prontuário) obtidos antes da morte no processo de identificação para o estabelecimento da identidade. Porém nem sempre o preenche adequadamente, reduzindo assim o seu valor clínico, administrativo e legal. Fazem parte do prontuário do Cirurgião-Dentista de Cuiabá-MT, os exames anamnéticos, os exames radiográficos e um odontograma. Porém para uma parcela significativa dos participantes os modelos de gesso e as condições prévias (registro das condições bucais antes do atendimento) da cavidade bucal do paciente não o fazem. Concluiu-se que não há até a presente data uma punição formal (ética e legal) para os Cirurgiões-Dentistas cujos prontuários não venham a se prestar ao estabelecimento da identidade de um indivíduo. A única punição é a contra propaganda para o Cirurgião-Dentista frente aos pacientes e a sociedade como um todo. / Abstract: The quality of a odonthologic programming have direct relation with its capability in supply determination need inside of the profession pratice.

An adaptive quality-based fingerprints matching using feature level 2 (minutiae) and extended features (pores)

Mngenge, Ntethelelo Alex 25 November 2013 (has links)
M.Ing. (Electrical and Electronic Engineering Technology) / Automated Fingerprint Recognition Systems (AFRSs) have not been very effective so far in matching poor quality fingerprints because the challenges involved in low quality fingerprint matching are quite different from high quality fingerprint matching. The difficulty is due to three main reasons: (i) poor quality of fingerprints in terms of the clarity of ridge information due to harsh working conditions, diseases and aging, (ii) failure to acquire adequate minutiae points after segmentation and (iii) large non-linear distortion due to pressure variations which causes ridges to deform. Thus, low quality fingerprint recognition is a difficult problem which still needs more attention. This is because the accuracy of a fingerprint matching module heavily depends on the quality of the fingerprint probe image. Poor quality fingerprints lead to maximization of False Acceptance Rate (FAR) instead of True Acceptance Rate (TAR). As a result, researchers have suggested that extended features must be incorporated to improve accuracy. These features have been successfully used by Latent Print Experts (LPEs) for crime investigation purposes to increase matching accuracy for fingerprints collected from crime scenes with those stored in the national or international databases. There are three categories of fingerprint features: (i) level 1 (e.g. delta), (ii) level 2 (e.g. minutiae) and (iii) level 3 or extended features (e.g. pores). In this work, improvements have been made through fusion of minutiae and extended feature scores together with the fingerprint image quality. However, fusion algorithms designed so far are not adaptive, i.e. they assume that the effect of the quality of the image on the matching score is the same for different matchers based on different features. To test this assumption, this work adopted an algorithm from the literature that first assigns quality score to different regions of a fingerprint. Quality scores assigned to each region of the segmented fingerprint was mapped to extracted minutiae and extended features (pores). The overall quality rating of each of these were calculated as the sum of all quality scores assigned to regions. This procedure helped the designed fusion algorithm to assign more weight on highly reliable features and less weight on unreliable features. Two experiments conducted for rating minutiae and pore features that are based on this procedure, showed that quality scores for features under study do not stay constant. An adaptive weighted sum fusion algorithm was designed, implemented, tested and compared to non-adaptive algorithms, namely, simple sum and weighted sum fusion. The proposed adaptive weighted sum differs from traditional weighted sum fusion algorithm in that it uses weights assigned to each feature based on the quality map of each region of the fingerprint as opposed to the whole image. The performance of the system was tested using PlyU High Resolution Fingerprint (HRF) Database. Two performance measures were used to rate the proposed algorithm in comparison with simple sum and traditional weighted sum, namely, Area Under the Curve (AUC) and Equal Error Rate (EER). Both these performance measures showed that the algorithm proposed in this work outperforms both simple sum and traditional weighted sum fusion approaches. The proposed algorithm yields an improvement of 8% and 13.33% in EER and AUC, respectively for weighted sum fusion and 2% and 4.8% in EER and AUC, respectively for simple sum fusion.
