In a unit testing environment, understanding the relationship between production classes and test classes has implications for overall maintenance and hence systems development costs. Equally, the fault-proneness of each type may have a similar influence on the level or required maintenance. In this paper, we explore two aspects of the differences between test and production classes in a commercial...
In this paper, we introduce FlowSifter, a systematic framework for online application protocol field extraction. FlowSifter introduces a new grammar model Counting Regular Grammars (CRG) and a corresponding automata model Counting Automata (CA). The CRG and CA models add counters with update functions and transition guards to regular grammars and finite state automata. These additions give CRGs and...
An integrated network platform for Beizao Mine of Longkou Mining Group which is formed by seas digital system and industrial ring Ethernet+fieldbus is analyzed. Based on this platform, "five major information systems" of Beizao Mine which are office automation system, production safety monitoring system, underground staff location system, seas industrial area television and gas detector...
Using a nano-focus x-ray source we have been able to visualize structures down to 150 nm in x-ray projection images. Because of their unlimited depth of focus, these sources don't restrict the specimen size in case of 3D tomographic imaging. Simulation studies have shown that optimization of the detector response curve and switching from a reflective x-ray target to a transmission target might allow...
In this paper we have shown the application of QWI to the fabrication of QCW laser bars. Extended reliability has been shown as well as the recent development of higher power bars and stacks.
In this paper, we demonstrated two types of magnetization control: in device A uniaxial strain is applied by a strain-coupled piezoelectric material and magnetization direction is controlled by electrostatic voltages; in device B magnetization is controlled by spin-orbit effective field generated intrinsically by non-polarized dc current. In both cases we report reversible manipulation of magnetization...
We have used the x-ray fluorescence signal from copper selectively excited with a ∼10 keV photon beam from the Argonne Advanced Photon Source to probe low levels of copper in sputtered CdTe cells. Through a peel-off technique that separates the evaporated Cu/Au back contact from the CdTe, we are able to determine where the Cu resides after cell preparation is finished. With a 3 to 4 nm Cu layer under...
To amend the defects of low perceptual transparency, low capacity, low security of the present information hiding technology in PDF files, we present a novel steganographic algorithm which is better in perceptual transparency property, capacity and security. Attributive to the insensitiveness of PDF files to the seriation of entries, the algorithm helps to realize the information hiding in high degree...
