A study of an offensive signal system using words rather than numbers and including automatics
It is the purpose of this study to (1) present a signal system for offensive football including automatics; (2) compare it with whose systems already in use; and (3) present the reactions of nine coaches using it at the junior high school, senior high school, junior college, and professional levels.

Digital assistance design for analog systems : digital baseband for outphasing power amplifiers
… that can be leveraged to help analog/mixed-signal designers keep up with the technology scaling. It usually takes the form of predistorter or compensator in an analog/mixed-signal system and helps compensate the nonidealities in the system. Digital assistance takes advantage of the process …

Control of a Nonlinear Mach-Zehnder Interferometer for Regeneration Using Digital Signal Processing
… impairments degrade the quality of optical signals and limit the transmission reach. Phase modulated signals are susceptible to both amplitude and phase noises. Optical regenerators based on nonlinear Mach Zehnder interferometers (NMZIs) are able to suppress them both. To use a NMZI as a …

Dynamic Signal Coordination Models for a Network With Oversaturated Intersections
… research presents the development of a dynamic signal coordination model (DSCM) for a network (one-way and two-way streets) with oversaturated intersections. The model is formulated as a discrete optimization problem with the objective to maximize the number of vehicles released by the network. …

Development and Applications of Multi-Objectives Signal Control Strategy during Oversaturated Conditions
… under-saturated conditions, operation of traffic signal systems during congestion requires careful consideration and analysis of the underlying causes of the congestion before developing mitigation strategies. The objectives of this research are to provide a practical guidance for practitioners to …

Improving traffic signal performance using high-resolution data
… and the task seems even more challenging for signalized arterials due to lack of traffic monitoring and data collection system. This research aims to improve the traffic signal performance based on the collected high-resolution traffic signal data and the derived performance measures by the …

Upgrading of Milner and Klipfontein Road Southbound Approach to alleviate traffic issues
… a country's sustainability is reliant upon these systems. In many countries, the increase in population has congested the CBD areas, forcing people to migrate outside of the CBD. This has resulted in urban sprawl. However, the apartheid era has resulted in urban sprawl in South Africa, which left …

System-level trace signal selection for post-silicon debug using linear programming
… because of the lack of the observability of all signals on chip. Trace buffers are a often used structure in post-silicon debug that stores the state of a selected signal into an on-chip buffer, where they can be offloaded for a debugger to observe. However, because of area limitations for debug …
