This chapter describes a mobile, open-circuit ventilated hood system for measuring real-time gaseous exchange in large ruminants at the farm level. It uses improvements in technology for the determination of O 2 , CO 2 and CH 4 contents, measurements of air flow, absolute pressure, temperature and relative humidity, system control and data acquisition. Details of the three experiments conducted to test the calorimetry system are presented. All animals adapted easily to confinement in the hoods and there were no indications of discomfort or stress in the animals.
You have probably heard about MBT (model-based testing), but like many software-engineering professionals who have not used MBT, you might be curious about others' experience with this testdesign method. From mid-June 2014 to early August 2014, we conducted a survey to learn how MBT users view its efficiency and effectiveness. The 2014 MBT User Survey, a follow-up to a similar 2012 survey (http:// robertvbinder.com/real-users-of-model-based-testing/), was open to all those who have evaluated or used any MBT approach. Its 32 questions included some from a survey distributed at the 2013 User Conference on Advanced Automated Testing. Some questions focused on the efficiency and
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
