With the proliferation of mobile computing devices there is an increasing demand for applications supporting collaboration among users working in the field and in the office. A key component for collaboration in this domain is sharing and manipulation of information using very different devices and communications. We propose a novel, data-centric collaboration paradigm, where each user can obta...

aim of this paper is to search and find ways and methods of constructivism teaching and learning ideas inteaching the architectural design studio. the objective is to extract all the positive things constructivism has to offer the architectural design studio for efficient teaching and effective learning. although there are similarities in the curricula of training architects all over the world,...

although the history of communication is as old as history of human society, the speed and volume of communication with the advent of electronic era in the 19th century created a revolution in the communication technology. at a time when prussia was traversing the path of industrialization and the number of companies investing in different industries was increasing by the day, the company of si...

The advances in mobile devices, wireless communication, and messaging technologies have given rise to a vast range of new services, for heterogeneous user environments. These include a collaboration service that can be accessed regardless of the nature of user devices and physical capabilities of the user. In this paper, we present an overview of our research project CAROUSEL, universal accessi...

Globally distributed collaboration is becoming increasingly common nowadays, yet research on this topic has remained limited. Literature on global collaboration can be classified into two streams: pessimistic and optimistic perspectives on the impact of distance and time zone differences. Researchers in the pessimistic tradition found support for the proposition that collaboration suffers from ...

We present a framework for pen-based, multi-user, online collaboration in mathematical domains. This environment provides participants, who may be in the same room or across the planet, with a shared whiteboard and voice channel. The digital ink stream is transmitted as InkML, allowing special recognizers for different content types, such as mathematics and diagrams. Sessions may be recorded an...

We introduce a link intensity-based ranking model for recommending relevant users in human interaction networks. In open, dynamic collaboration environments enabled by Service-oriented Architecture (SOA), it is ever more important to determine the expertise and skills of users in an automated manner. Additionally, a ranking model for humans must consider metrics such as availability, activity l...

Real-time and multimedia applications like multi-party collaboration, internet telephony and distributed command control systems require the exchange of information over distributed and heterogeneous nodes. Multiple data types including voice, video, sensor data, real-time intelligence data and text are being transported widely across today's information, control and surveillance networks. All ...
