In prior work, Cimini has presented Lang-n-Send, a pi-calculus with language definitions. this paper, we present an extension of calculus called Lang-n-Send+m. First, revise Lang-n-Send to work transition system specifications rather than its specifications. This revision allows the use negative premises in deduction rules. Next, extend monitors and ability sending receiving regular expressions...

It is cheap to process epidemiological data from optical mark read (OMR) questionnaires. Respondents should use a pencil to complete OMR questionnaires, but many will not unless these are supplied. Sending pencils and erasers is expensive. Does sending pencils and erasers increase the response rate as cost-effectively as sending reminders, or does this decrease the error rate and offset data ch...

2. Latency. Latency, also known as delay, is a measure of the time it takes to traverse the network, including going through any intermediate routers. It represents the elapsed time between a sending node sending a packet and receiving node receiving that packet. For example, on my system, a local loopback (sending a packet back to the same machine) gives me a latency of 0.043 ms (milliseconds)...

The hidden terminal is classified as the sending hidden terminal and receiving hidden terminal in this paper. The quantitive analysis of hidden terminal problem and simulation-based analysis of its mechanism is discussed. Through the extensive ns2 simulations the detail comparison for the impact of sending hidden terminal and receiving hidden terminal to the performance of TCP is also given. Th...
