introduction: the aim of this study was to compare the effect of post space preparation with gates glidden drills or hand files on the sealing ability of gutta-percha or resilon obturation materials. materials and methods: one-hundred and four single-rooted human teeth were instrumented and divided into four experimental groups (n=21 each) and two groups of positive and negative control (n=10)....

We present a neural network architecture to predict a point in color space from the sequence of characters in the color’s name. Using large scale color–name pairs obtained from an online color design forum, we evaluate our model on a “color Turing test” and find that, given a name, the colors predicted by our model are preferred by annotators to color names created by humans. Our datasets and d...

In 1985, Doignon and Falmagne introduced surmise relations for representing prerequisite relationships between items within a body of information for the assessment of knowledge. Often it is useful to partition such a body of information into sub-collections. As we are primarily interested in psychological applications, we refer to these sub-collections as tests. We extend the concept of surmis...

Quantitative identification of physical changes, developments and dynamic position of urban green space is considered as the first step in its planning. By means of the aerial photos taken in 1956, 1974, and 1994 as well as the Quick Bird satellite image captured in 2006, this study has dealt with changes in per capita green space in Khorramabad during these years. First, geometric corrections ...

The equivalence problem under local unitary transformation for n–partite pure states is reduced to the one for (n− 1)–partite mixed states. In particular, a tripartite system HA⊗HB ⊗HC , where Hj is a finite dimensional complex Hilbert space for j = A,B,C, is considered and a set of invariants under local transformations is introduced, which is complete for the set of states whose partial trace...

We assessed parents’ beliefs about treatment credibility and effectiveness and examined the influence of these beliefs on subsequent treatment participation. Seventysix parents completed the Credibility/Expectancies Questionnaire—Parent Version (CEQP), and subsequently participated in treatment for their child’s clinically referred conduct problems. The key findings were that: (a) the CEQ-P is ...

We present a study of the practical use of a simulationbased automatic test pattern generation (ATPG) for model checking in large sequential circuits. Preliminary findings show that ATPGs which gradually build and learn from the state-space has the potential to achieve the verification objective without needing the complete state-space information. The success of verifying a useful set of prope...
