One difficult task in information modeling is to adequately address the impact of time. This paper briefly reviews some popular approaches for modeling temporal data and operations, then provides a conceptual framework for classifying temporal information, and proposes data model patterns to address time-impacted tasks such as modeling histories, and tracking entities across time as they migrat...

today, organizations need innovations in order to grow and survive. organization that can`t deliver innovative products and services to market continually, would be doomed to failure. but key of innovation is in the innovative behavior of employees. various factors affect the innovative behavior of the employees. work engagement of employees is one of the factors which can affect this behavior....

Implicit user modeling has always long since played an important role in supporting personalized web-based e-learning environments and is increasingly important in other learning environments such as serious games. Its main concern is to unobtrusively and ubiquitously learn from a learner’s previous experiences and characteristics, in order to adapt the services to their personal needs. An empi...

confined masonry buildings are used in rural and urban areas of iran. they performed almost satisfactoryduring past moderate earthquakes of iran. there is not a methodology in iranian seismic code (standard 2800-3rdedition) to estimate their capacities quantitatively. in line with removing this constraint, an attempt is made to studyin-plane behavior of two squared confined masonry walls with a...

A four-county Indiana survey of the vast majority (approximately 90%) of the attorneys and public agency caseworkers involved in court actions on child abuse cases revealed considerable conflict over each other's role. The survey replicated the method used in previous research, which had yielded distinctly positive and negative results. The author discusses particularities of the four-county ar...

free surface modeling plays an important role in some ocean structures design, especially in oscillating water column (owc) devices. boundary element method (bem) is a suitable method for free surface modeling due to its simplicity, quick solving, and low data storage requirement. in this paper, bem was used for free surface modeling in owc chamber and out of it. linear kinematic and dynamic bo...

Process Modeling is a widely used concept for understanding, documenting and also redesigning the operations of organizations. The validation and usage of process models is however affected by the fact that only business analysts fully understand them in detail. This is in particular a problem because they are typically not domain experts. In this paper, we investigate in how far the concept of...

The free distribution, unauthorized usage, and illicit sharing of copyrighted digital contents have become a common phenomenon with the rapid triple-play progress. The digital home network (DHN) is confronted with the open issue of digital rights management, and there is a lack of a formalized usage control model as well as some killer applications. The paper proposes a role-based cross-domain ...

The Object Role Modeling language (ORM2) is nowadays the most widespread fact-based conceptual modeling language in the business world. Recently, it has been proposed an encoding of the core fragment of ORM2 (called ORM2 zero ) into the description logic ALCQI, allowing the use of reasoning technologies in the analysis of the schemas. A number of services has been defined there based on the FO ...
