WMCSA - Dynamic Documents: Mobile Wireless Access to the WWW
1994 First Workshop on Mobile Computing Systems and Applications, 1994Co-Authors: M.f. Kaashoek, T. Pinckney, Joshua A. TauberAbstract:We propose dynamic documents as an approach to extending and customizing the WWW/Mosaic for mobile computing platforms. Dynamic documents are programs executed on a mobile platform to generate a document; they are implemented as Tcl scripts. We have modified the NCSA Mosaic web client to run the dynamic documents it retrieves through a modified Tcl Interpreter. The Interpreter is designed to execute only commands that do not violate safety. To hide the latencies of slow links we have modified the Mosaic client to perform caching and prefetching. The policies for caching and prefetching can be under control of dynamic documents, allowing the strategies to be document specific. Using dynamic documents, we have built an adaptive E mail browser that employs application specific caching and prefetching strategies. Both the browser and the displayed E mail messages are dynamically customized to the mobile computing environment in which they run.

Dynamic Documents: Extensibility and Adaptability in the WWW
1994Co-Authors: Frans M. Kaashoek, T. Pinckney, Joshua A. TauberAbstract:We propose dynamic documents as an approach to extending and customizing the Mosaic interface to the WWW. Mosaic implements rigid policies that limit the range of environments in which it can function. Dynamic documents overcome this problem by allowing documents to implement their own policies. Dynamic documents are programs executed at a Mosaic client to generate a document; they are implemented as Tcl scripts. We have modified the NCSA Mosaic client to use a modified Tcl Interpreter to run the dynamic documents it retrieves. The Interpreter is designed to execute only those commands that do not violate safety. We have used dynamic documents to configure an adaptable Mosaic client to a mobile environment. The use of dynamic documents allows adaptable clients to adjust to a variety of mobile platforms and network environments. We have used the adaptive client and dynamic documents to build an adaptive e-mail browser that employs application-specific caching and prefetching strategies...

Implementation of a Management Agent fo r Interpreting Obligation Policy
1996Co-Authors: Damian A. Marriott, Morris SlomanAbstract:Distributing management functionality into intelligent management agents has now been accepted as the way to manage large scale distributed systems. However, it is necessary to easily change the functionality of the agents to adapt to changing application requirements. Agents which interpret policy can have their behaviour changed by modifying the policies loaded in them. This paper gives an overview of a management policy notation which can be used to define both authorisation policies (what activities a manager is permitted or forbidden to do) and obligation policies (the activities a manager must or must not perform). We also give an overview of the tools for specifying, refining and storing policies in domains. The emphasis of the paper is on the implementation issues for an obligation policy Interpreter. The manager agents are implemented using a Tcl Interpreter within a CORBA Distributed Programming environment.

Tool command language automation of the modular ion cyclotron data acquisition system (MIDAS) for data-dependent tandem Fourier transform ion cyclotron resonance mass spectrometry.
Rapid communications in mass spectrometry : RCM, 2003Co-Authors: Michael A. Freitas, Eric R. King, Stone D.-h. ShiAbstract:This manuscript describes the addition of data-dependent automation to the modular ion cyclotron resonance data acquisition system (MIDAS). The automation is made possible by developments and incorporation of a tool command language (Tcl) Interpreter for automated acquisition. To accomplish the automation, real-time generation of excitation waveforms and scriptable data post-processing has been implemented into the MIDAS source code. In addition a new excitation event has also been added to allow for run-time generation of a single notch stored waveform inverse Fourier transform (SWIFT) excitation event. Examples of these new features and discussion of their enhancement to the existing data station are presented.
