This article describes a methodology for the capture and analysis of hybrid data. A case study in the field of reasoning with multiple representations--specifically, in computer programming--is presented to exemplify the use of the methodology. The hybrid data considered comprise computer interaction logs, audio recordings, and data about visual attention focus. The capture of the focus of visu...

Through the use of conditional, local nonparametric estimation, this paper tracks the effects that data revisions have on core and total inflation as measured by Personal Consumption Expenditures and the Consumer Price Index. The purpose of this paper is two-fold. The first is to investigate whether data revisions of PCE does have an impact on total inflation in regards to the exclusions-from-c...

Viewing Ci(n,m) as entries of the Ni|Ni matrix Ci, we note that this matrix is symmetric because both the displacement vector D~d(m,n)D~D{~d(n,m)D~D~d(n,m)D and the track-segment length l(n,m)~l(m,n) are invariant under the time reversal operation n<m such that C(n,m)~C(m,n). Furthermore, the diagonal elements of Ci take values Ci(k,k)~1 because D~di(k,k)D~li(k,k) for all k. In general, 0ƒCi(n,...

DRAFT, UPDATED—August 22, 2017. Each time a learner in a self-paced online course is trying to answer an assessment question, it takes some time to submit the answer, and if multiple attempts are allowed and the first answer was incorrect, it takes some time to submit the second attempt, and so on. Here we study the distribution of such “response times”. We find that the log-normal statistical ...

islamic architecture has been a great influence on different parts of the world, even so there are some similar factors, but the aspect of culture will make the polarization between them. upon the vast spread that muslims had in the 7th century (a.d.) islamic culture and belief moved in different continents from the fareast parts of asia to the west of the mediterranean. at the beginning islam ...
