In stack related algorithms TOP initially point 0, index of elements in stack is start from 1, and index of last element is MAX.INIT_STACK (STACK, TOP) Algorithm to initialize a stack using array. TOP points to the top-most element of stack. 1) TOP: = 0; 2) Exit ...

Put it back in the robot and followed the instruction in the user manual to setup the robot in simple discovery using the fastDDS middleware. Tried out the 'ros2 topic list' on my controlling PC and this looked good. However when I tried to run the localisation noderos2 launch turtlebot4...

the client signature is consistent with that in the backend request. 2. Create a to-be-signed string using the standard request and other related information. 3. Calculate a signature using the AK/SK and to-be-signed string. 4. Add the generated signature to an HTTP request as a header ...
Stacks and Queues: Stacks and Queues are two of the most important data structures in programming: A Stack has two main operations: Push: Pushes an element into the stack Pop: Returns the last element that was put into the stack...
// Skip kernels issued in other queues. if (KTI.AsyncInfo && !(AsyncInfoWrapperMatcher(*KTI.AsyncInfo))) continue; Idx = I; break; } auto KTI = KTIR.getKernelTraceInfo(Idx); if (KTI.AsyncInfo && (AsyncInfoWrapperMatcher(*KTI.AsyncInfo))) reportError("Kernel '%s'", KTI.Kernel->get...
Conventional stacks make extensive use of queuing and buffering to mitigate context switches and keep CPUs and NICs busy, at the cost of substantially increased cache footprint and latency. Can we adopt a bufferless event model that reimposes synchrony and avoids large queues that exceed cache siz...
In the future I might add the option to turn it into an actual daemon by using an extra parameter. This means that, for now, in order to kill it, you just need to press CTRL-C in the same terminal where the AL entity was started. The Linux platform includes two "external triggers...
