In order to decouple the real-time operating system platform from the application software, ARINC 653 defines an API called APplication EXecutive (APEX). Each application software is called a partition and has its own memory space. It also has a dedicated time slot allocated by the APEX API. Within each partition, multitasking is allowed. The ...
The Crew Module Atmospheric Re-entry Experiment (CARE) is an experimental test vehicle for the Indian Space Research Organisation's future ISRO orbital vehicle called Gaganyaan. [1] It was launched successfully on 18 December 2014 from the Second Launch Pad of the Satish Dhawan Space Centre , by a LVM3 designated by ISRO as the LVM 3X CARE mission.
Applications can be reconfigured on spare modules if the primary module that supports them is detected faulty during operations, increasing the overall availability of the avionics functions. Communication between the modules can use an internal high speed Computer bus , or can share an external network, such as ARINC 429 or ARINC 664 (part 7) .

The Vympel R-23 (NATO reporting name AA-7 Apex) is a medium-range air-to-air missile developed by Vympel in the Soviet Union for fighter aircraft. An updated version with greater range, the R-24, replaced it in service. It is comparable to the American AIM-7 Sparrow, both in terms of overall performance as well as role.
The APEX telescope is a modified ALMA (Atacama Large Millimeter Array) prototype antenna and is at the site of the ALMA observatory. APEX is designed to work at sub-millimetre wavelengths, in the 0.2 to 1.5 mm range — between infrared light and radio waves — and to find targets that ALMA will be able to study in greater detail.
The module is the measure of gear tooth size which is normally used for metric system gears. It is similar to the Diametral Pitch (DP), which is commonly used for UK system (inch measure) gears but they differ in the units used and in that they bear a reciprocal relationship. Module is the pitch circle diameter divided by the number of teeth.
Restoring panda habitat. Habitat loss and fragmentation remain the biggest threat to wild pandas. By the early 2010s, some of China’s most prominent panda experts had warned that the success in ...
