Finally, based on these distance measures, some similarity measures between IVIFSs are defined, and the similarity measures are applied to pattern recognitions with interval-valued intuitionistic fuzzy information.展开更多

Therefore, we present a 3D expression of intuitionistic fuzzy similarity measurement, make an analysis of the constraints for intuitionistic fuzzy similarity measurement, and redefine the intuitionistic fuzzy similarity measurement. Moreover, in view of the threat assessment problem, we give the system variables of attribute function and assessment index, set up the reasoning system based on intuitionistic fuzzy similarity measurement with orientation, and design the reasoning rules, reasoning algorithms and fuzzy-resolving algorithms. Finally, through the threat assessment, some typical examples are cited to verify the validity and superiority of the method.展开更多

Unlike fuzzy set, IFSs contain uncertainty named hesitance, which is contained in fuzzy membership function itself. Hence, designing fuzzy entropy is not easy because of many entropy definitions. By considering different fuzzy entropy definitions, fuzzy entropy on IFSs is designed and discussed. Similarity measure was also presented and its usefulness was verified to evaluate degree of similarity.展开更多

The test was repeated with sphincteric squeeze on urgent sensation. RESULTS: Rapid voluminous rectal distension resulted in a significant rectal pressure increase (P 〈 0.001), an anal pressure decline (P 〈 0.05) and balloon expulsion. The subjects felt urgent sensation but did not feel the 1^st rectal sensation. On urgent sensation, anal squeeze caused a significant rectal pressure decrease (P 〈 0.001) and urgency disappearance. Slow incremental rectal filling drew a rectometrogram with a "tone" limb representing a gradual rectal pressure increase during rectal filling, and an "evacuation limb" representing a sharp pressure increase during balloon expulsion. The curve recorded both the ist rectal sensation and the urgent sensation. CONCLUSION: The rectum has apparently two functions: transportation (conduit) and storage, both depending on the degree of rectal filling. If the fecal material received by the rectum is small, it is stored in the rectum until a big volume is reached that can affect a degree of rectal distension sufficient to initiate the defecation reflex. Large volume rectal distension evokes directly the rectoanal inhibitory reflex with a resulting defecation.展开更多

Firstly,camera calibration is performed by 40 mm gauge block to capture the images of table tennis ball in static and pressed state in an appropriate lighting condition. Then image binarization and extraction of image contour are carried out. The least square method is used to fit its center. Finally,the diameter,roundness and hardness are calculated. The measurement data are analyzed by using the method presented in this paper for table tennis ball with known parameter data and with unknown parameter data. Experimental results show that this method can improve measurement accuracy and provide a technical basis for the online testing and integration measurement of table tennis ball.展开更多

The latter holds that Damasio does not distinguish the concepts of phenomenal consciousness and self-consciousness and this has two kinds of consequences. One is that it cannot satisfactorily explain certain mental states (dreams, vegetative states); the other is that it has harmful consequences for animal ethics. I maintain that to compare the two theories we can only rely on our pre-theoretical intuition of consciousness. Thus, I argue that Dam^tsio's theory combines more with our intuitions. One of the reasons is that the cases that Block describes as phenomenal consciousness without access consciousness (and without self-consciousness) are best explained as being cases of mind without consciousness. Dam^sio's theory can also explain those referred cases which are theoretically problematic. Moreover, Dam^isio has a threshold model (an expression by Barry Dainton), which is something that Block seems to ignore. This model fits well with the intuitions and neurological knowledge that we normally have on animal consciousness. Dam^isio's core self and his theory of emotions and feelings allow us to understand why we feel compassion for animals. Therefore, we are able to develop an animal ethics, which does not mean that we are required to do so. So even though Damasio does not solve the mystery of consciousness, he should not be the subject of Block's criticism.展开更多

There were 134 Iranian male and female learners participating in this study. A SCIA questionnaire containing 30 items was developed and validated to assess EFL learners' preferences for intervention categories. Moreover, Myers-Briggs Type Indicator (MBTI) was used in the research. Results indicated that whereas in some cases no significant differences were observed, there mostly existed numerous significant differences among language learners with different personality traits and their preferences for SCIA.展开更多

Historically, the roles of financial/accounting theory and cognitive psychology have been extensively studied and documented in attempting to explain individual financial decision-making. More recently, neuroscience has made substantial contributions to learning how prospective financial decisions and outcomes affect brain activity and observed decision-making behavior. The evidence from neuroscience indicates that up to 90% of our decisions are initiated at the unconscious level, which is only beginning to be investigated in a systematic manner. Integrating these findings from multiple disciplines, including recent contributions from neuroscience, has many implications, not only with respect to personal and corporate financial decisions and how markets work, but also as an essential component in the tool box of the general decision maker.展开更多

It is characteristic mg of the educational five consecutive stages of students' presentation of PPT, the teacher's evaluation, the teacher's presentation, classroom interaction, and summary to enable students actively participate in class teaching and to guide them to construct RVL (the root-based vector lexicon). The lexicon is constructed with the help of vector in the form of a diamond structure by utilizing the root "anthrop" functioning as a priming root and roots like "vest", "vor", "hab", "mov", and "somn' serving as target roots it motivates directly. The lexicon avails to accept new roots and make them mixed with existing roots by meaning relation or collocation to help students retrieve words effectively and enhance their ability of studying English vocabulary展开更多

Hemingway's use of objective correlatives was a trace mark, and the literary editors at The New Yorker urged their writers to slow down the emphasis on movement and plot in order to recreate a certain mood which would favour the perception of objects, anecdotes, and details. The impressionistic device works very much in the same way that an advertisement would do. It is meant to persuade the audience. The apparently non-commitant vision of reality shows in fact the author's point of view. The apparent simplicity is meant for a very wide audience and its deepest meaning suggests the scope of the particular visual aids working at the deepest level of consciousness展开更多

METHODS: A total of 4536 polyps from 1096 patients over an eight-year period (1987-1995) were retrospectively examined. Adenomas showing at least 50% of serrated architecture were called SAs by three reviewing pathologists. RESULTS: Ninety-one (2%) of all polyps were called SAs, which were found in 46 patients. Invasive carcinomas were seen in 3 out of 46 (6.4%) patients, of whom one was a case of familial adenomatous polyposis (FAP). A male preponderance was noted and features of a mild degree of dysplasia were seen in majority (n=75, 83%) of serrated adenomas. Follow-up ranged 1-12 years with a mean time of 5.75 years. Recurrences of SAs were seen in 3 (6.4%) cases, synchronous SAs in 16 (34.8%) cases and metachronous SAs in 9 (19.6%) cases. CONCLUSION: Invasive carcinoma arising in serrated adenoma is rare, accounting for 2 (4.3%) cases studied in this series.展开更多
