We propose a rigorous comparison of two widely known dynamic information flow mechanisms: Secure Multi-Execution (SME) and Multiple Facets (MF). Informally, it is believed that MF simulates SME while providing better performance. Formally, it is well known that SME has stronger soundness guarantees than MF. Surprisingly, we discover that even if we approach them to enforce the same soundness gu...

Tracking information flow (IFLOW) is crucial to understanding the evolution of news stories. We present analysis and experiments for IFLOW between company announcements and newswire. Error analysis shows that many FPs are annotation errors and many FNs are due to coarse-grained document-level modelling. Experiments show that document meta-data features (e.g., category, length, timing) improve f...

Building Information Modelling (BIM) is a detailed process of designing and building in construction industry collaboratively by using one integrated system generated computer rather than separate the work drawings. On other hand, it provides large amount benefit terms cost saving time, much better accuracy estimation reducing arithmetical error any amendment due to loss information. Existing s...

  One of an important factor in the success of organizations is the efficiency of knowledge flow. The knowledge flow is a comprehensive concept and in recent studies of organizational analysis broadly considered in the areas of strategic management, organizational analysis and economics. In this paper, we consider knowledge flows from an Information Technology (IT) viewpoint. We usually have tw...
