Timeline Builder Assistant

Current human spaceflight requirements limit the number of hours a crewmember can be outside of the habitation unit to 8 hours in a 48-hour period, and 24 hours in a seven-day period. This time must be appropriately balanced to complete science, exploration, and maintenance tasks. Off-days can be used for site transit (traverse), crew rest, or intra-vehicular activities (IVA). The “building blocks” approach to mission design organizes crewmember activities for extra-vehicular activities (EVA) at each investigation site based on the types of tasks that must be completed and the tools required to complete each task. Building blocks colocate payload and crewmember information for timeline construction. Similar tasks or tasks that accomplish similar goals are grouped into blocks and distributed according to EVA requirements for a specified number of days, including allocations for site arrival activities and departure preparations.

Can augmented reality reduce "road rage?"

This week’s Question: A new "CarNote" app from the Eindhoven University of Technology in the Netherlands aims to use augmented reality to improve the driving experience and reduce "road rage." CarNote's driver-facing periscope lens and transparent display projects information from a smartphone, allowing users behind the wheel to communicate and signal intentions. For example, a driver in a rush to a hospital could notify those in nearby vehicles, potentially reducing aggressive behavior like confrontations or honking the horn. The technology even has a "like" system that allows drivers to register or rate fellow travelers on the road. What do you think? Can augmented reality reduce "road rage?"

Key Considerations for Powertrain HIL Test

Safety, availability, and cost considerations can make performing thorough tests of embedded control devices using the complete system impractical. Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently. During HIL test, the physical system that interfaces to an embedded control device is simulated on real-time hardware, and the outputs of the simulator mimic the actual output of the physical system. The embedded controller “thinks” it is in a real system. HIL simulation meticulously tests embedded control devices in a virtual environment before proceeding to real-world tests of the complete system. This application note covers recommended best practices for powertrain HIL testing.

PLCs Improve Control of Radio Broadcasts

PLCs are slowly replacing the outdated hardware and software used at many remote transmitter sites in radio and TV broadcasting applications.Broadcasting employs the latest technology in many areas, but controlling the broadcast hardware connected to the antenna and the related transmission power, source, and facilities is usually still a low-tech operation. Typically, a broadcast engineer will drive to the unattended transmitter, translator, or repeater site to flip switches and make other manual adjustments (Figure 1).

JPF-NAS Extension of Java Pathfinder

Java PathFinder (JPF) version 7 provides basic support for verifying the distributed Java applications. It can receive a distributed Java application as input that is perceived as multiple Java processes. However, JPF does account for communication between processes of the distributed application, and it thus cannot be used to verify any realistic distributed Java application. Applying JPF on distributed applications requires a model of inter-process communication (IPC) and process aware scheduling.
