Information flow topology is crucial in the control of connected autonomous vehicles. It has a substantial influence on the platoon's performance, especially in scenarios with imperfect communication. To address this issue, this study provides a real-time switching topology technique for improving the platoon's performance under various types of imperfect communication situations and constant packet dropout rates. First, a discrete sliding mode controller with a double power reaching law is designed for a nonlinear heterogeneous vehicle dynamic model with packet loss. Then, Lyapunov ...

As the percentage of renewable energy sources grows, excess electrical power from renewables can be converted using electrolyzers to produce hydrogen, which can be stored, and later utilized by industries, homes, or the transportation system. Further, electrolyzers can also be utilized for frequency and voltage control to improve the stability of the power system. In this paper, a novel electrical circuit model for a 400W PEM electrolyzer is designed and validated using the experimental data from a reported paper for a 400W electrolyzer. To demonstrate its adaptive feature, the proposed 400W m...

Boksa Marine Design (BMD) is now an employee-owned naval architecture and marine  engineering partnership. On August 1, BMD President Nick Boksa, P.E. restructured the firm from a privately-owned business to...

The stability of inks is an essential parameter in the fabrication process. The ink-jet printing technique involves a jetting process, in which the inks are ejected from a small orifice, which can be clogged if the the ink is not stable. Thus, stabilising agents are commonly used in inks. It is of great interest to study the effect of stabilisers on the ink stability to achieve an optimal performance and reliability of the ink formulation. The stability study of two ink formulations containing different stabilisers will be presented in this application note using the stability analyzer MultiSc...

This paper presents a method for allocating transmission rates in a communication network that uses knowledge of the size of the file to be transmitted to seek to obtain the benefits of shortest remaining processing time (SRPT) scheduling. It provides fairness among file transmissions taking into account their sizes and the congestion on the links they use. The proposed approach is based on network utility maximisation (NUM), but with utility functions that vary in time depending on the remaining file size. A parameterized family of utility functions is proposed. For each value of the paramete...
