Advances in compiler and virtual machine technologies support spread of programming environments with automated memory management, such as Java. These environments rely on garbage collection to reclaim memory that is no longer used. While in the domain of garbage collection research, every proposed garbage collector improvement is accompanied with detailed analysis of the collector overhead [De...
No current garbage collector combines space efficiency, low collector times, and mutator (application) locality for contemporaneously allocated objects. For example, free-list allocation coupled with mark-sweep collection achieves space efficiency, but poor mutator locality. On the other hand, contiguous (bump-pointer) allocation with copying collection provides mutator locality but poor space ...
PURPOSE To examine the anatomical variation of normal human collector channel orifices and their relationship with Schlemm's canal. METHODS Ten human anterior segments fixed by immersion or perfusion were dissected radially and further divided by fine dissection into corresponding inner and outer wall segments. The tissues were dehydrated, critical-point dried, sputter coated, and examined by...
A disk pressed from commercial SnO2 powder, sandwiched between two nickel screen current collectors, was used as a lithium-ion secondary anode. Its electrochemical lithium insertion–extraction behavior was investigated by galvanostatic charge–discharge and galvanostatic intermittent titration (GITT) using a microcurrent on one current collector. The transelectrode voltage was measured to monito...
Michael Chen and Kunle Olukotun Computer Systems Lab, Stanford University Abstract In this paper, we introduce a novel garbage collector for Java to be used for processors with speculative threads support like the Hydra chip multiprocessor (CMP). Thread speculation permits parallel execution of sections of sequential code with data dependencies enforced in the hardware, eliminating the need for...
Bama is one of the major concentrating plant in Iran which treats nearly 1500 tons per day sulphidic lead and zinc ore. Large amount of oxidized ore exist in Bama which has been extracted along with sulphidic ore. The main objective of the present investigation was the up-grading of the ore from Goshfil which is the major deposit in Bama. The ore contained about 16% zinc as smithsonite, about 1...
In this paper, a multi-objective optimization method is implemented by using of genetic algorithm techniques in order to determine optimum configuration of solar chimney power plant. The objective function which is simultaneously considered in the analysis is output power of the plant. Output power of the system is maximized. Design parameters of the considered plant include collector radius (R...
Collection of biological particles is the first and critical step for any biological agent detection system. Towards our goal of capturing and detecting airborne biological entities in real time, here we investigate on the design of an electrostatic particle capture system. We report on the capture of airborne 100 nm diameter polystyrene nanoparticles as a model system, in swirling flows under ...
Advanced bipolar transistors play a vital role in RF/Microwave applications. But they need to satisfy stringent demands on device performance parameters such as β, gm, and fT. Many of the bipolar technologies developed to meet these demands are vertical structures and suffer from many non−ideal effects at high collector current densities. In the present work, to enhance the performance limits o...
In this study, exergy analysis of a flat plat solar collector in a closed circuit has been performed using existing experimental data and the effects of utilization of the collector with upper, lower and side reflectors alone and together with lenses on exergy efficiency have been considered. Then, based on a mathematical model, optimization analysis has been performed. Unlike the past studies,...
