In the wake of the global financial crisis, a pressing need exists for improving investor friendliness, especially the transparency and interoperability of the financial statements of public companies. eXtensible Business Reporting Language (XBRL) and XBRL taxonomies can accomplish this objective. In the U.S., the Securities and Exchange Commission (SEC) has mandated that all public companies m...
ion was performed by trained data abstractors (research associates and medical students) using a standardized abstraction form. An instruction book was available and all abstractors attended a training session on the content and coding of each data element. Data abstractors attended monthly meetings to resolve any questions and review coding rules. Abstractors were not aware at the time of abst...
We have developed a bit-reversal algorithm (BRAVO) using vector permute operations, which is optimal in the number of permutations, and its cache-optimal version (COBRAVO). Our implementation on PowerMac G5 shows 2– 4.5 fold improvement for small data sets and 15–75% improvement for large data sets (depending on the data element size) over the best known approach (COBRA).
Shared space coordination models such as Linda are ill-suited for structuring applications composed of erroneous or insecure components. This paper presents the Secure Object Space model. In this model, a data element can be locked with a key and is only visible to a process that presents a matching key to unlock the element. We give a precise semantics for Secure Object Space operations and di...

In the era of data sharing and systems interoperability, the automation of data schema alignment has become a priority. Discovering data mappings is the aim of many alignment approaches that have been described in the literature and the effectiveness of which depends on data specifications. In this context, we propose a method for mappings formalization that allows automated data integration pr...
The efficiency of a nudging data assimilation algorithm using higher order finite element interpolating operators is studied. Numerical experiments are presented for the 2D Navier–Stokes equations in three cases: shear flow an annulus, forced disk with off-center cavity, and box all satisfying Dirichlet boundary conditions. In cases, second interpolation coarse-grain shown to outperform first i...
the present research was conducted to accomplish two purposes. firstly, it aimed to explore and describe schematic structure or what halliday and hassan (1989, p.64) have called “generic structure potential” (gsp) of american english, iranian persian and iranian english newspaper editorials within systemic functional linguistics. secondly, a quantitative cross-comparison was made to investigate...
