AN INVESTIGATION OF COMMON CODING ERRORS IN OPEN SOURCE GRAPHICAL USER INTERFACE CODE
No full textIntroduction: This thesis investigates the occurrence of coding errors in the Open Source Software (OSS) Graphical User Interface (GUI) code. Characteristics of coding errors in the OSS GUI code are explored and analyzed so that guidelines are proposed to lower the influence of coding errors in OSS GUI software.
Background: This thesis recognizes the increased prominence of, as well as the increased total volume of OSS GUI code within modern software applications. This thesis seeks to identify whether specific types of errors manifest themselves more frequently in GUI code. The rationale behind this investigation is that: if specific errors are known to occur in specific locations then they can be more easily identified; if specific errors are due to specific causes then they can be more easily recognized in earlier stages of software development.
Methods: Common coding errors were selected and examined in example OSS code using an automatic code inspection. An analysis of results from this inspection identified the frequency and location (i.e. in GUI or non-GUI code) of the common coding error. An initial sample of OSS GUI projects was selected to be examined and a wider range of OSS GUI projects was randomly chosen to evaluate the results that were obtained from the initial sample.
Results: It was found that there are some differences in the type of errors within differing portions of source code. Certain types of coding errors were more frequently identified in GUI code than non-GUI code and corresponding typical GUI coding error-prone behaviors were summarized.
Discussion: Awareness of these differences helps predict errors during the earlier stages of software development. Comprehension of these GUI coding error-prone behaviours contributes to prevent typical GUI coding errors as much as possible during the whole lifecycle of OSS GUI projects

Effect of Wu-Wei-Gui-Shao decoction on complete Freund's adjuvant-induced arthritis rats
No full textPurpose: To investigate the anti-rheumatic potential of Wu-Wei-Gui-Shao decoction (WGD) and its possible mechanism of action.
Methods: Adjuvant arthritis (AA) rats were established using complete Freund's adjuvant. The rats were then given different doses of WGD (100, 200, and 400 mg/kg, for 28 days). The anti-arthritic effects of WGD were evaluated. Furthermore, the in vitro anti-arthritic effects of WGD and its related mechanisms were also determined in MH7A cells.
Results: WGD (100 - 400 mg/kg) exhibited significant anti-rheumatic properties after 28 days of treatment, inhibiting paw edema in AA rats, reducing arthritis score and thymus and spleen index, and inhibiting the tumor necrosis factor (TNF)-α and the interleukin (IL)-6. In addition, the results of in vitro cell experiments also confirmed that WGD reduced the release of cytokines, as well as mRNA levels of matrix metalloproteinase (MMP) -2, -3, and -9.
Conclusion: These findings suggest that WGD can be further developed as a traditional Chinese medicine to treat rheumatic arthritis.

Effects of W Alloying on the Lattice Distortion and Wear Behavior of Laser Cladding AlCoCrFeNiWx High-Entropy Alloy Coatings
No full textFriction and wear properties of hot working die steel at above 800 degrees C are of particular interest for high temperature applications. Here, novel AlCoCrFeNiWx high-entropy alloy (HEA) coatings have been fabricated on the surface of hot working die steel by laser cladding. The effects of the as-prepared AlCoCrFeNiWx HEA coatings on the microstructure and high temperature friction and wear behavior of hot working die steel are investigated through scanning electron microscopy (SEM), electron probe microanalysis (EPMA), X-ray diffraction (XRD), and X-ray absorption fine structure (XAFS). Having benefited from the formation of W-rich intermetallic compounds after the addition of W elements, the high temperature wear resistance of the coatings is obviously improved, and friction coefficient shows a large fluctuation. The microstructural characteristics of the AlCoCrFeNiWx HEA coatings after the high temperature wear resistance test shows a highly favorable impact on microstructure stability and wear resistance, due to its the strong lattice distortion effect of W element on BCC solid solutions and the second phase strengthening of the W-rich intermetallic compounds. These findings may provide a method to design the high temperature wear resistant coatings
