Blade: A Data Center Garbage Collector

An increasing number of high-performance distributed systems are written in garbage collected languages. This removes a large class of harmful bugs from these systems. However, it also introduces high tail-latency do to garbage collection pause times. We address this problem through a new technique of garbage collection avoidance which we call BLADE. BLADE is an API between the collector and ap...

Wavelength modulation spectroscopy using novel mechanical light chopper blade designs

We describe two mechanical light chopper blade designs that can be used, with a monochromator and broadband light-source-based spectroscopy setup, to perform wavelength modulation spectroscopy. The left and the right half of a beam emerging from a monochromator would have spectral distributions that are skewed to longer and shorter wavelengths about the central wavelength for positive grating o...

Lubrication Characteristics Between Bush And Blade Of Swing Compressor

This paper presents the lubrication characteristics between a bush and a blade of a swing compressor that was developed for a new type of compressor for an air conditioner using alternative refrigerants. The mixed lubrication analysis that simultaneously solved the motion equations of the bush and the blade, the lubrication equation and the rough surface contact equation was performed. Moreover...

Effect of blade profile on the performance characteristics of axial compressor in design condition

The choice of geometrical shape of the blades has a considerable effect on aerodynamic performance and flow characteristics in axial compressors. In this paper, the effects of the blades shape on the aerodynamic design characteristics are investigated based on Streamline Curvature Method (SCM). Initially, the Streamline Curvature Method (SCM) is used for designing a two-stage axial compressor. ...
