Inspired by work in semi-conservative collection, we have implemented a mostly-copying collector for an object-oriented language, including support for object pinning. Our collector efficiently manages fragmentation by measuring page residency and determining where copying can be most effective. This work in progress will form the foundation of our ongoing work in real-time collection.

This paper presents several microwave power ampl~ier designs that promise high power and broad bandwidth, while meeting the eficiency and linearity requirements of advanced radar and communication systems. Power amplifiers are designed based on an ultra-high f~u~ (>450 GHz) selective buried sub-collector (SBSC) HBT technology [1]. SBSC HBTs are fabricated on prepatterned sub-collector mesas. Th...

let $g$ be a finite group and $gamma(g)$ the prime graph of $g$‎. ‎recently people have been using prime graphs to study simple groups‎. ‎naturally we pose a question‎: ‎can we use prime graphs to study almost‎ ‎simple groups or non-simple groups? in this paper some results in‎ ‎this respect are obtained and as follows‎: ‎$gcong s_p$ if and only‎ ‎if $|g|=|s_p|$ and $gamma(g)=gamma(s_p)$‎, ‎whe...

Abstract—Solar water heating is a thermodynamic process of heating water using sunlight with the help of solar water heater. Thus, solar water heater is a device used to harness solar energy. In this paper, a modified solar water heating system (MSWHS) has been proposed over flat plate collector (FPC) and Evacuated tube collector (ETC). The modifications include selection of materials other tha...

Real-time Java is becoming a viable platform for real-time applications, bringing new challenges to a garbage collector. A real-time collector has to be incremental as not to cause deadline misses by suspending an application for too long. In particular, if a real-time collector has to relocate objects in the heap, it must do so incrementally and transparently to the application. This is usuall...

in this paper, we investigate the existence of a positive solution of fully fuzzy linear equation systems. this paper mainly to discuss a new decomposition of a nonsingular fuzzy matrix, the symmetric times triangular (st) decomposition. by this decomposition, every nonsingular fuzzy matrix can be represented as a product of a fuzzy symmetric matrix s and a fuzzy triangular matrix t.

This paper presents BBox, a digital black box to provide for authentic archiving (and, consequently, forensic evidence) for remote auditing in distributed systems. Based upon public key cryptography and trusted computing platforms, the BBox employs standard primitives to ensure the authenticity of records during the transmission from devices to the collector, as well as during their storage on ...

This paper presents the design of a prototypical system to support creative group discussions, like brainstorms. The central concept of this design is the Idea-collector: a tangible input device that is used to organize information displayed on an electronic whiteboard. A working prototype of the Idea-collector was made, following a range of early prototypes. Initial user tests are encouraging ...

We analyze the integration of automatic memory management in a real-time context. We focus on integrating a real-time (copying) garbage collector with hard real-time static-priority periodic tasks. This integration is done by considering the copying collector as an aperiodic task served by a polling server. We analyze the schedulability of this system for any polling server parameters. This ana...

This paper presents BBox, a digital black box to provide for authentic archiving in distributed systems. Based upon public key cryptography and trusted computing platforms, the BBox employs standard primitives to ensure the authenticity of records during the transmission from devices to the collector, as well as during their storage on the collector and retrieval by auditors. Besides presenting...
