Software safety (sometimes called software system safety) is an engineering discipline that aims to ensure that software, which is used in safety-related systems (i.e. safety-related software), does not contribute to any hazards such a system might pose. There are numerous standards that govern the way how safety-related software should be ...
The Power of 10 Rules were created in 2006 by Gerard J. Holzmann of the NASA/JPL Laboratory for Reliable Software. [1] The rules are intended to eliminate certain C coding practices that make code difficult to review or statically analyze.
Software classification is based on the potential for hazard(s) that could cause injury to the user or patient. [1] Per [[IEC 62304|IEC 62304:2006] + A1:2015], the software can be divided into three separate classes: The SOFTWARE SYSTEM is software safety class A if: the SOFTWARE SYSTEM cannot contribute to a HAZARDOUS SITUATION; or
It is the software safety analyses that drive the system safety assessments that determine the DAL that drives the appropriate level of rigor in DO-178B. The system safety assessments combined with methods such as SAE ARP 4754A determine the after mitigation DAL and may allow reduction of the DO-178B software level objectives to be satisfied if ...
The Software Level, also known as the Development Assurance Level (DAL) or Item Development Assurance Level (IDAL) as defined in ARP4754 (DO-178C only mentions IDAL as synonymous with Software Level [10]), is determined from the safety assessment process and hazard analysis by examining the effects of a failure condition in the system. The ...
Computers in the classroom include any digital technology used to enhance, supplement, or replace a traditional educational curriculum with computer science education. As computers have become more accessible, inexpensive, and powerful, the demand for this technology has increased, leading to more frequent use of computer resources within ...
Besides, the virtual classroom provides a social learning environment that replicates the traditional "brick and mortar" classroom. [133] Most virtual classroom applications provide a recording feature. Each class is recorded and stored on a server, which allows for instant playback of any class over the course of the school year. This can be ...
The Framework for Authentic Intellectual Work (AIW) is an evaluative tool used by educators of all subjects at the elementary and secondary levels to assess the quality of classroom instruction, assignments, and student work. The framework was founded by Dr. Dana L. Carmichael, Dr. M. Bruce King, and Dr. Fred M. Newmann.
