Chinese pure alexia
No full textTwo Chinese pure alexic patients are reported. C.Y.T. had a circumscribed lesion in the left occipital lobe, the same location as the classic cases of pure alexia in other languages. Y.Y.X. was diagnosed with Balint's syndrome characterized by bilateral damage in the parietal and occipital lobes. The Chinese script is logographic and non-alphabetic. Nevertheless, the neuroanatomy of early processing in reading Chinese appears to be the same for readers of alphabetical and non-alphabetical scripts. Both patients displayed a 'radical-by-radical' reading strategy which is analogous (and possibly functionally equivalent) to 'letter-by-letter' reading in alphabetic patients. There was an association between constructional apraxia and a deficit in processing the visual form of Chinese characters for Y. Y. X. However, C. Y. T. had intact visuospatial function and displayed no impairment to the processing of character form. The implications of the data from pure alexic patients to our understanding of oral reading in Chinese are discussed
Dyslexia in Chinese: Clues from cognitive neuropsychology
No full textIn this review, we describe a series of cognitive neuropsychological studies of Chinese speaking aphasic patients that reveal subtypes of acquired dyslexia and dysgraphia in Chinese. These subtypes can be understood with reference to a cognitive framework that assumes reading and writing to dictation in Chinese depends on the division of labor between two pathways: a lexical-semantic pathway and a direct or nonsemantic pathway. This framework generates a number of predictions about the types of literacy problems that might be observed in native Chinese speakers who are learning to read and write. We argue that the language environment, and specifically the type of script used to read and write, will play a role in determining the phenotype of dyslexia in Chinese. We conclude that dyslexia in Chinese can be caused by psycholinguistic impairments at multiple levels including orthographic, semantic (morphological), and phonological processing.In this review, we describe a series of cognitive neuropsychological studies of Chinese speaking aphasic patients that reveal subtypes of acquired dyslexia and dysgraphia in Chinese.

Implementation of WG Stream Cipher with Involution Function
No full textAbstractThis paper present a new hardware design of WelchGong (WG)128 cipher. The proposed WG Stream cipher use an involution function block, for increasing the security of private data. The hardware complexity of involution block is very less. Together with the involution block the randomness property of the resulting WG cipher will increases
Acquired dyslexia and dysgraphia in Chinese
No full textUnderstanding how the mappings between orthography and phonology in alphabetic languages are learned, represented and processed has been enhanced by the cognitive neuropsychological investigation of patients with acquired reading and writing disorders. During the past decade, this methodology has been extended to understanding reading and writing in Chinese leading to new insights about language processing, dyslexia and dysgraphia. The aim of this paper is to review reports of patients who have acquired dyslexia and acquired dysgraphia in Chinese and describe the functional architecture of the reading and writing system. Our conclusion is that the unique features of Chinese script will determine the symptoms of acquired dyslexia and dysgraphia in Chinese
Exploring the Effect of Constructional Ability in Character Writingfor Chinese
No full text
This study investigated the writing abilities of 15 brain-damaged patients, with and without drawing difficulties. The task was Chinese character copying. All brain-damaged patients had difficulties in copying characters; however, drawing-disable made this task much more difficult. We also found that the structure of Chinese character is an important influencing factor in character copying. The probability of the enclosed structure characters to be copied incorrectly is higher than the characters of other three structures, and single structure characters are most likely to be written correctly.</p
The role of classification and reference vessels in the design of inland fairways for commercial vessels – contribution to the Workshop of WG 141 Design Guidelines for Inland Waterways
No full textThe Pianc WG 141 is proceeding in the conception of Design Guidelines for Inland Waterways. WG 141 aims to produce its first draft in the end of 2015. Part of the forseen content are classification of waterways and the object of reference vessels. The role of those subjects will be presented and discussed in the Workshop, that WG 141 will give during the Smart Rivers 2015 Conference, scheduled at the 8th of September.Hydraulic EngineeringCivil Engineering and Geoscience

No full textAn overview on the recent results on the engineering and characterization of sorption materials, PCMs and TCMs investigated in the working group WG A1 “Engineering and processing of TES materials” of IEA SHC Task 42 / ECES Annex 29 (Task 4229) entitled “Compact Thermal Energy Storage” is presented
Pt-AlGaN/GaN HEMT-sensor layout optimization for enhancement of hydrogen detection
No full textThis paper reports on the layout optimization of Pt-AlGaN/GaN HEMT-sensors for enhancing hydrogen sensor performance. Sensors with gate width and length ratios Wg/Lg from 0.25 to 10 were designed, fabricated and tested for the detection of hydrogen gas at 200 °C. Sensitivity, sensing current variation and transient response are directly related to the sensor gate electrode Wg/Lg ratio. The obtained results demonstrated a 217 % increase in sensitivity and 4630 % increase in sensing current variation at 500 ppm H2 for a Wg/Lg from 0.25 to 10. In addition, the detection limit was lowered to 5 ppm. Transient characteristics demonstrated faster sensor response to H2, but slower recovery rates with increasing ratio.Accepted author manuscriptElectronic Components, Technology and Material
