COMBINED DEEP AND SHALLOW KNOWLEDGE IN A UNIFIED MODEL FOR DIAGNOSIS BY ABDUCTION

Fault Diagnosis in real systems usually involves human expert’s shallow knowledge (as pattern causes-effects) but also deep knowledge (as structural / functional modularization and models on behavior). The paper proposes a unified approach on diagnosis by abduction based on plausibility and relevance criteria multiple applied, in a connectionist implementation. Then, it focuses elicitation of deep knowledge on target conductive flow systems – most encountered in industry and not only, in the aim of fault diagnosis. Finally, the paper gives hints on design and building of diagnosis system by abduction, embedding deep and shallow knowledge (according to case) and performing hierarchical fault isolation, along with a case study on a hydraulic installation in a rolling mill plant.shallow knowledge, diagnosis, flow systems

The Role of the Integrated Network Concept in Elaborating the Territorial Development Choremes. Case Study: the Peri-Urban Zone of the Municipium of Bistriţa

The choreme is a pattern of high generalization and abstracting concerning the status, the dynamics and the way of organizing a territory. This foreshadows territorial patterns in implementing the future anthropic structures, the evolutive directions of settlements, the best areas for developing and the critical ones, which claim specific measures of rehabilitation, the areas with some potential in development and the underdeveloped ones. Working out the choreme pattern of development relies on a series of theories (the theory of polarized space, the network theory, the theory of force axis, the theory of the rising poles, the theory of behavior, the clusters theory, and the fractals theory), and concepts of development (the concepts of system, region, potential, norms, sustainable development, discontinuation, stability, and the resource concept) aiming at scientific grounding the territorial transforming actions. The summary of these theories and concepts which are at the basis of territorial development concretize themselves in a new innovating concept of development – the concept of integrated network or the polarized space. The concept of integrated network represents, in thinking the organizing of the territory, an operational component, having the role of a vector in delimitating and establishing the locations of different categories of geographical territorial systems, which are natural or anthropic, already existent or in the makin

Numerical Analysis of Flow in Kaplan Turbine Runner Blades Anticavitation Lip with Modified Hydro-dynamic Profile

In order to increase the lifetime of runner blades of Kaplan turbines damaged by cavitation erosion, an anticavitation lip is attached to the periphery of the runner blades on the suction side. The anticavitation lip overtakes the cavitation pitting which appears between the runner blades and the runner chamber. A blade with the original anticavitation lip was modeled using CAE. The numerical simulations showed the tip vortex position and the source of the cavitation erosion. Using these data, a modified profile of the anticavitation lip was designed

Assessing the intralobular ducts in mouse mandibular gland

In order to quantify the types of intralobular ducts, we used five adult male mice, sacrificed by cervical dislocation, after exposure to anesthetic. After euthanasing the animals, the mandibular glands were histologically processed. We sectioned the tissue at 5 µm thickness and stained the slides using Goldner’s trichrome staining procedure. We captured images on four different microscopic fields for each animal, subsequently counting each type of intralobulary duct. The granular ducts were the most numerous, followed by the intermediary ones and striated ducts with the lowest number

Observations regarding the structure of the parotid and mandibular glands in rabbit

Our study aims to investigate the histological structure of two major salivary glands in adult rabbit. We used 5 adult rabbits, 3 males and 2 females, from a private breeder in Cluj. We harvested the salivary glands, fixed them in 10% buffered formalin, dehydrated in ethanol (increasing concentration), clarified in n-butanol and embedded in paraffin. The sections (5 µm thickness) were stained with Goldner’s trichrome method and examined with an Olympus BX41 light microscope. Histologically, parotid gland in rabbit contains only one type of acini, which presents morphological characteristics of serous acini. In mandibular gland, the acini are all the same, similar to the ones in parotid gland. Concerning the general aspect and dimension they are much larger and polymorphic
