Algebraic dynamics of certain gamma function values
Abstract We present significant numerical evidence, based on the entropy analysis by lumping of the binary expansion of certain values of the Gamma function, that some of these values correspond to incompressible algorithmic information. In particular, the value Γ(1/5) corresponds to a peak of non-compressibility as anticipated on a priori grounds from number-theoretic considerations. Other fundamental constants are similarly considered. This work may be viewed as an invitation for other researchers to apply information theoretic and decision theory techniques in number theory and analysis
The effects of English proficiency on the processing of Bulgarian-accented English by Bulgarian-English bilinguals
This dissertation explores the potential benefit of listening to and with one’s first-language accent, as suggested by the Interspeech Intelligibility Benefit Hypothesis (ISIB). Previous studies have not consistently supported this hypothesis. According to major second language learning theories, the listener’s second language proficiency determines the extent to which the listener relies on their first language phonetics. Hence, this thesis provides a novel approach by focusing on the role of English proficiency in the understanding of Bulgarian-accented English for Bulgarian-English bilinguals.
The first experiment investigated whether evoking the listeners’ L1 Bulgarian phonetics would improve the speed of processing Bulgarian-accented English words, compared to Standard British English words, and vice versa. Listeners with lower English proficiency processed Bulgarian-accented English faster than SBE, while high proficiency listeners tended to have an advantage with SBE over Bulgarian accent.
The second experiment measured the accuracy and reaction times (RT) in a lexical decision task with single-word stimuli produced by two L1 English speakers and two Bulgarian-English bilinguals. Listeners with high proficiency in English responded slower and less accurately to Bulgarian-accented speech compared to L1 English speech and compared to lower proficiency listeners. These accent preferences were also supported by the listener’s RT adaptation across the first experimental block.
A follow-up investigation compared the results of L1 UK English listeners to the bilingual listeners with the highest proficiency in English. The L1 English listeners and the bilinguals processed both accents with similar speed, accuracy and adaptation patterns, showing no advantage or disadvantage for the bilinguals.
These studies support existing models of second language phonetics. Higher proficiency in L2 is associated with lesser reliance on L1 phonetics during speech processing. In addition, the listeners with the highest English proficiency had no advantage when understanding Bulgarian-accented English compared to L1 English listeners, contrary to ISIB.

Drawing, Handwriting Processing Analysis: New Advances and Challenges
International audienceDrawing and handwriting are communicational skills that are fundamental in geopolitical, ideological and technological evolutions of all time. drawingand handwriting are still useful in defining innovative applications in numerous fields. In this regard, researchers have to solve new problems like those related to the manner in which drawing and handwriting become an efficient way to command various connected objects; or to validate graphomotor skills as evident and objective sources of data useful in the study of human beings, their capabilities and their limits from birth to decline

Shortest Route at Dynamic Location with Node Combination-Dijkstra Algorithm
Abstract— Online transportation has become a basic
requirement of the general public in support of all activities to go
to work, school or vacation to the sights. Public transportation
services compete to provide the best service so that consumers
feel comfortable using the services offered, so that all activities
are noticed, one of them is the search for the shortest route in
picking the buyer or delivering to the destination. Node
Combination method can minimize memory usage and this
methode is more optimal when compared to A* and Ant Colony
in the shortest route search like Dijkstra algorithm, but can’t
store the history node that has been passed. Therefore, using
node combination algorithm is very good in searching the
shortest distance is not the shortest route. This paper is
structured to modify the node combination algorithm to solve the
problem of finding the shortest route at the dynamic location
obtained from the transport fleet by displaying the nodes that
have the shortest distance and will be implemented in the
geographic information system in the form of map to facilitate
the use of the system.

The effects on the phonological processing skills of disabled readers of participating in direct instruction reading programs
This thesis examines the effects of phonics-emphasis Direct Instruction reading programs on the phonological processes of students with teacher-identified reading problems in nine northern and western Melbourne primary schools. The students (131 males and 75 females, mean age 9.7 years, standard deviation 1.2 years) were assigned to the treatment condition or to wait-list comparison groups. Based on the results of a program placement test of rate and accuracy, students were assigned to one of two entry points into the Corrective Reading program (A, B1). The students in the intervention group received 60-65 lessons (in groups of five to ten students) from teachers at their schools, or, for some students, at a resource centre for surrounding schools. An additional study, with younger (mean age 8.8 years) less advanced readers involved a similar design and teaching approach. The pr ogram, Teach Your Child to Read in 100 Easy Lessons, was presented to thirteen students in two settings. When compared with a similar cohort of wait-list students, the students in each program made statistically significant and educationally important gains in such phonologically-based processes as word attack, phonemic awareness, and spelling; and, statistically significant gains, of at least moderate effect size, in phonological recoding in lexical access and phonological recoding in working memory. A further question involved the prediction (from pretest scores) of those students who would not make progress in word attack solely from the reading programs. In this thesis, only the presence or absence of the reading programs predicted improvement in word attack. The studies in this thesis contribute to the long-standing debate on how best to ensure that children learn to read; to the understanding of the relationship between phonemic awareness and reading; to an understanding of the effects of the current system on at-risk children; and, how additional or alternative approaches more attuned to the findings of reading research may improve the effectiveness of the system
