Some researchers have also focused on hardware defects to trace the source; these include spinning velocity fluctuations of the polygon mirror in the laser printer and the imperfections of the paper feeding mechanism, which result in geometric distortions in the document that can serve to characterize individual laser printers.
Some common root causes of the rolling stock failures are electrical/mechanical overloading, installation failure, software failure, hardware failure, material defects are calibration errors.
Heterogeneous cores, hardware failures or manufacturing defects can possibly cause irregular topologies in a Network-on-Chip.
In this paper, the hardware and software architecture of quartz wafer defect inspection system is introduced.
In our context, a fault is a defect or flaw that occurs in a hardware or software component of the system.
According to Charles Huang, co-founder of Red Octane, creators of the Guitar Hero franchise and of the gaming hardware startup Green Throttle: "Startups should know their return and defect rates before they try to scale.
Cyclic Redundancy Codes (CRCs) offer protection against random bit errors caused by environmental interference and some hardware faults, but typically do not defend against most design defects.
As competition intensifies, development of complicated hardware products and the decrease in development cycle lead to increasing design defect risk in hardware products, resulting in all kinds of problems such as unsafe product, product development failure and so on.
When compared to the mass production of increasingly more reliable and powerful hardware, software development is craft-like and labor-intensive, prone to defects and delays.
