Many of the current software systems rely on garbage collectors for automatic memory management. This is also the case for various software systems in realtime applications. However, a real-time application often requires an incremental working style of the underlying garbage collection, which renders the garbage collector more complex and less trustworthy. We present a formal verification of t...

Starting from a theoretical understanding of the issues involved in the implementation of a heap garbage collector in a logic programming system with built-in tabling, and from an actual collector that did not take tabling (i.e. suspended computations) into account we have build two working heap garbage collectors (one mark&slide, one mark&copy) for XSB on top of a CHAT implementation model for...

This paper presents a new algorithm for distributed garbage collection and outlines its implementation within the Network Objects system. The algorithm is based on a reference listing scheme augmented by partial tracing in order to collect distributed garbage cycles. Our collector is designed to be flexible thereby allowing efficiency, expediency and fault-tolerance to be traded against complet...

This paper reports our experiences with a mostly-concurrent incremental garbage collector, implemented in the context of a high performance virtual machine for the Java programming language. The garbage collector is based on the “mostly parallel” collection algorithm of Boehm et al. and can be used as the old generation of a generational memory system. It overloads efficient write-barrier code...

Generational garbage collection algorithms achieve efficiency because newer records point to older records; the only way an older record can point to a newer record is by a store operation to a previously-created record, and such operations are rare in many languages. A garbage collector that concentrates just on recently allocated records can take advantage of this fact. Such a garbage collect...

Execution of programs with various data structures often requires dynamic memory management based on garbage collection for better productivity, robustness, and program integrity. In spite of its benefits, garbage collection has not been widely used in embedded real-time systems partly because it often causes unpredictable pause delay. Guaranteeing real-time operations with garbage collection a...

A pilot plant bioenergy recovery system from swine waste and garbage was constructed. A series of experiments was performed using swine feces (SF); a mixture of swine feces and urine (MSFU); a mixture of swine feces, urine and garbage (MSFUG); garbage and a mixture of urine and garbage (AUG). The system performed well for treating the source materials at a high organic loading rate (OLR) and sh...

In this paper we present a series of tiny programs that verify that a Prolog heap garbage collector can find specific forms of garbage. Only 2 out of our tested 7 Prolog systems pass all tests. Comparing memory usage on realistic programs dealing with finite datastructures using both poor and precise garbage collection shows only a small difference, providing a plausible explanation why many Pr...

Now a days, there are a number of techniques which are purposefully used and are being build up for well management of garbage or solid waste . Zigbee and Global System for Mobile Communication (GSM) are the latest trends and are one of the best combination to be used in the project. Hence,a combination of both of these technologies is used in the project . To give a brief description of the pr...

This document contains supplemental results and derivations for the paper “Asset Pricing with Garbage”. These include cross-sectional results for 25 portfolios formed using a double sort of garbage and expenditure betas, alternative test assets for the Fama MacBeth regressions in the paper, alternative weighting schemes for the crosssectional GMM test in the paper, a test using a linear stochas...
