Real time operating systems the sporadic server


Real-time systems consist of two different tasks, periodic and aperiodic sporadic tasks. Each of these tasks can have a hard or a soft deadline. When a system, containing both non real-time tasks, and real-time tasks, is faced with an overload situation scheduling its tasks is absolutely critical in order to guarantee the correctness of the system. That is, keeping the hard deadlines and also to guarantee good average response time for the soft deadline tasks.

Transistor radio circuit diagram


In this instructable i'll show you how to make a fully functional AM Radio using only 3 transistors and some recycled components. We'll need some electronic components and any other thinks that you like to add for modify the radio. The ferrite coil from am radio and a variable tunning capacitor sintonize the frecuency and the other circuits is amplification and selectivity.

Mm blue books


An exercise book or composition book is a notebook that is used in schools to copy down schoolwork and notes. A student will usually have a different exercise book for each separate lesson or subject.
