Halo: A Windowing system for Angel
نویسنده
چکیده
This paper describes the Halo windowing system for the Angel 1, 2] operating system currently being developed at City University. The aim of this windowing system is to provide a clean parallel object-oriented design utilising the uniied resources in the single address space of Angel. Halo provides an object design for a basic window library which can then be extended (subclassed) into the GUI components which we associate with today's windowing systems. Halo does not try to provide a radical user interface or consider the graphical details of GUI design, but instead concentrates on parallelism the windowing system structure, generic access to basic primitives and how GUI components can be built from these through extensibility.

Mycobacteriophages BPs, Angel and Halo are closely related viruses isolated from Mycobacterium smegmatis, and possess the smallest known mycobacteriophage genomes, 41,901 bp, 42,289 bp and 41,441 bp, respectively. Comparative genome analysis reveals a novel class of ultra-small mobile genetic elements; BPs and Halo each contain an insertion of the proposed mobile elements MPME1 and MPME2, respe...
متن کاملWindowing Effects of Short Time Fourier Transform on Wideband Array Signal Processing Using Maximum Likelihood Estimation
During the last two decades, Maximum Likelihood estimation (ML) has been used to determine Direction Of Arrival (DOA) and signals propagated by the sources, using narrowband array signals. The algorithm fails in the case of wideband signals. As an attempt by the present study to overcome the problem, the array outputs are transformed into narrowband frequency bins, using short time Fourier tran...

متن کاملA High-performance Hardware-based High-assurance Trusted Windowing System
TRW's Trusted X Window System prototype established that it is possible to build a high assurance windowing system, given a trusted operating system as a base. This paper describes an extension of that architecture that uses custom designed hardware to provide a high-performance, low-cost windowing system while retaining the highassurance character of the original design.
