Lightweight generic random ferns for multi-target augmented reality on mobile devices
No full textProposed use lightweight generic random ferns (LGRF), a fast key-point classifier designed for multi-target augmented reality (AR) on mobile devices. LGRF uses binary features of image patches for both object recognition and keypoint matching of multiple objects, and stores probabilities in a single bit representation to reduce memory requirements. As a result, LGRF can perform simultaneous object recognition and keypoint matching in real time with low memory consumption, making it suitable for multi-target AR on mobile devices
Compatibility Analysis of the Turbo Controller Area Network (TURBO CAN)
No full textGiven the increased amount of data traffic in in-vehicle networks with more systems now included in vehicles, enormous amounts of research have recently focused on providing reliable and inexpensive quality of service (QoS) for in-vehicle communication systems. To support high-speed data processing while maintaining backward compatibility with controller area network (CAN) for in-vehicle communication systems, the turbo controller area network (TURBO CAN) was proposed, combining the standard baseband CAN signal with a passband modulated signal. In this paper, we demonstrate both an improvement in the performance and the validity of the backward compatibility of the TURBO CAN system. To be specific, we provide passband channel modeling of the CAN system based on the channel gain and the noise characteristics as measured in an actual vehicle environment. Using these measurements, we also provide proper criteria for determining the power constraint of the passband signal to achieve a highly compatible system by analyzing the channel capacity of TURBO CAN as well as the bit error rate (BER) of a standard CAN receiver.

Enhancing shock wave energy dissipation in metallosupramolecular polymer by tuning metal-imidazole coordination interactions
No full textThe development of materials capable of shock wave energy dissipation (SWED) is critical for modern protective applications. In this study, metallosupramolecular poly(dimethylsiloxane) (PDMS) networks cross-linked with Zn2+, Cu2+, and Ni2+ ions and imidazole ligands were designed to enhance SWED by leveraging the dynamic nature of metal-ligand coordination bonds. A laser-induced shock wave technique revealed that Cu2+ cross-linked PDMS exhibited superior SWED performance, likely due to coordination rearrangement dynamics occurring within a relevant timescale for shock wave dissipation. Time-temperature superposition (TTS) analysis indicated that while associative ligand exchange may assist in shock attenuation, metal-ligand bond dissociation plays a more dominant role under extreme shock conditions. DFT calculations further demonstrated that coordination geometry significantly influences SWED performance, with Cu2+ in square planar (trans) coordination exhibiting greater rupture susceptibility. These findings highlight the tunability of metal-ligand interactions as an effective strategy for optimizing energy dissipation in metallosupramolecular polymers. Additionally, they provide a comprehensive SWED mechanism analysis by synergistically integrating a laser-induced shock wave test and DFT calculations.

Letter from K.W. Lee to Friends of Michi Weglyn, November 1, 1997
No full textA letter from K. W. (Kyung Won) Lee, an investigative journalist who wrote for the Sacramento Union, to the Friends of Michi Weglyn. Lee wrote that Weglyn was instrumental in the campaign to free Chol Soo Lee, a Korean American man was on death row, but later had his convictions overturned. Lee also wrote that other Japanese American activists were instrumental to the success of this campaign.These materials are from box 73 and 74 of the Frank Chin Papers. The Frank Chin Papers contain personal and professional correspondence between Frank Chin and Michi Weglyn relating to particular projects on which either author was working as well as files related to the Day of Remembrance Tribute to Michi Weglyn
