The MSP430FR4xx microcontrollers are primarily targeted at remote control application that are equipped with infrared modulation function and an LCD display. The infrared modulation combinatory logic works with rich peripheral resources (for example, timers, RTC, WDT, and SPI) to generate infrared waveforms for transmitting infrared signals with minimal software overhead and intelligent power c...

In this paper we present a proposal to integrate the POSIX.1 executiontime clocks and execution-time timers into the Ada 95 language. This proposal defines a new package named Ada.CPU Time and describes the modifications done to the GNAT front-end and run-time to support it. Additionally this proposal discusses some usage schemes of this new interface.

Experiments in mechanics can often be timed by the sounds they produce. In such cases, digital audio recordings provide a simple way of measuring time intervals with an accuracy comparable to that of photogate timers. We illustrate this with an experiment in the physics of sports: to measure the speed of a hard-kicked soccer ball.

The French Yellow Vests movement offers a case study for examining the logics and effects of avoidance institutional politics. brought together seasoned activists large share first-time protesters, i.e. social actors with no prior experience in collective action or party Drawing on in-depth ethnographic biographical interviews conducted latter, we argue that, paradoxically enough, avoiding poli...

The Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) are the protocols used by hosts and multicast routers to exchange their IP multicast group memberships with each other. This document describes ways to achieve IGMPv3 and MLDv2 protocol optimization for mobility and aims to become a guideline for the tuning of IGMPv3/MLDv2 Queries, timers, and counter values.

Radio Link Control (RLC) is the layer two protocol used in 3G UMTS cellular systems for flow control and error recovery. Due to the complexity of the protocol and the multitude of parameter configurations available, it is extremely difficult to model RLC analytically. Therefore we present a simulation model to study RLC performance in UMTS systems. We focus on the impacts of the poll prohibit t...

Multiple timing faults, although detectable individually, can hide each other’s faulty behavior making the faulty system indistinguishable from a non-faulty one. A set of graph augmentations are introduced for single timing faults. The fault detection capability of the augmentations is analyzed in the presence of multiple timing faults and shown that multiple occurrences of a class of timing fa...
