The present paper introduces a new data analyzer, a compression-based self-organizing recognizer, the PRDC-CSOR (Pattern Representation scheme using Data Compression – Compression based Self ORganizing Recognizer), with a preliminary application to image data. The PRDC-CSOR is an extension of the authors’ previously proposed pattern representation scheme using data compression (PRDC). Contrary to the traditional statistical-model-based recognition system methods, the PRDC-CSOR constructs itself using incoming data only. The basic tool, compressibility, is an approximation of the Kolmogorov complexity K(x) defined in an individual text x as a countermeasure against the Shannon entropy H(X) defined on an ensemble X. Due to this feature, a highly automatic self-organizing recognition system becomes possible as demonstrated in this paper. 相似文献

The effective usage of power facilities can be realized by leveling the fluctuating active power and compensating the reactive power. A fuzzy control strategy of superconducting magnetic energy storage (SMES) has been proposed for this purpose. The control results depend on the values of the scaling factors in fuzzy reasoning. Therefore, to obtain better control results, the scaling factor should be successively adjusted according to the load power fluctuations. In this paper, a control strategy based on autotuning of scaling factors and a fuzzy singleton reasoning method using backpropagation in a neural network is proposed for leveling load fluctuations. The prediction and revision of the teaching signal in terms of the energy of the SMES is proposed. The learning rate and the revision of the teaching signal are discussed. Better leveling of load power fluctuation is shown to be achievable by using fuzzy logic and neural networks. © 1997 Scripta Technica, Inc. Electr Eng Jpn, 120(2): 72–81, 1997 相似文献

The clinical study and in vitro study used with leukocytes were made of a case of food-dependent exercise-induced anaphylaxis induced by shrimp. A 26-year-old man experienced anaphylactic reaction of nasal obstruction, face edema and dyspnea while running 90 minutes after eating shrimp. He experienced similar episodes two years ago in his past history. IgE-RAST was positive for shrimp. Anaphylactic reaction and elevation of plasma histamine levels were verified by exercise challenge test after eating 100 g shrimp. At the same time, we verified the dedine of plasma cAMP levels after eating shrimp. In leukocyte stimulating test used with shrimp antigen, histamine level elevations, which were lower compared with calcium ionophore A23187 (Ca I 10(-6) M) stimulation, were recognized in dose dependent manner in this patient. But in normal subject, histamine level elevations were not recognized. We diagnosed him food-dependent exercise-induced anaphylaxis. It was suggested that there was relation between histamine release and decline of cAMP levels of plasma after eating shrimp in this case. 相似文献

In order to understand psychophysiological background of the individual differences on the diurnal variation of task performance, the task performance (i.e. the number of a simple adding calculation performed in one minute) was measured from 09:30 in the morning to 21:30 in the late evening for 9 healthy university male students. Heart rate (HR) and body temperature were also continuously recorded for 35 hours. There were two different types in the diurnal variation of the task performance; the morning type who shows the best performance in the morning, and the evening type who shows it in the evening. The body temperature curve during daytime in the evening type goes gradually up to the evening, on the contrary, that in the morning type rapidly rises to the maximum point in the morning or the afternoon. HR during daytime were higher in the morning type than the evening type. These results indicate that the morning type has a tendency of the higher mental tension compared with the evening type. And they also suggest that the individual differences on the task performance with a large mental concentration are caused by some kinds of subject's psychosomatic state. 相似文献

The mechanism of film formation and the properties of films deposited by the ionized-cluster beam technique were investigated. In this technique, strong adhesion of the film to the substrate and good crystalline deposition are expected.A high adhesive strength of over 100 kg cm-2 for Cu films on glass substrates was obtained in the experiments. The migration of adatoms consisting of ionized and neutral clusters was observed on the substrte surface. This effect, called the migration effect, can be considered to characterize film formation by cluster beam deposition and to produce good crystalline films. Si single crystals were obtained on Si substrates. A p-n junction photodiode was fabricated by the deposition of n-type Si on a p-type substrate. The diode shows improved spectral sensitivity in the UV region compared with that of commercially available solar cells. 相似文献

A eutectic solid of Al2 O3 –GdAlO3 was prepared by arc discharge and crushed to a eutectic powder of 3–125 μm. The powder was consolidated by the spark plasma system (SPS). The consolidated powder duplicated the eutectic structure: Al2 O3 and GdAlO3 were joined to each crystal. There were no flaws such as cracks or pores in the eutectic composite. The bending strength was half that of the eutectic composite prepared by unidirectional solidification. 相似文献

Amyloid β protein (Aβ) from Alzheimer's disease formed fibrillar aggregates and their morphology depended on oxidized and negatively charged liposomes. The morphology of fibrillar aggregates was affected by Cu2+, together with their growth kinetics. This is because Cu2+ inhibited the nucleation step in the formation of amyloid Aβ fibrillar aggregates by forming Aβ/Cu complex inactive to the growth of fibrillar aggregates. In addition, this is probably because Cu2+ affected the fibrillar aggregate formed on the surface of liposomes. These findings would give a better understanding of the formation mechanism of amyloid fibrils on biomembranes. 相似文献
