A flexible heterogeneous real-time digital image correlation system by Wang, Tianyi, Kemao, Qian, Seah, Hock Soon, Lin, Feng

“…First, the respective advantages of CPU and GPU in performing the fast Fourier transform-based cross-correlation (FFT-CC) algorithm and the inverse-compositional Gauss Newton (IC-GN) algorithm of the employed path-independent DIC (PI-DIC) method are elucidated. Second, based on the different properties and performances of CPU and GPU, a pipelined system framework unifying five Variants of combinations of CPU and GPU is proposed, which can be flexibly applied to various practical applications with different requirements of measurement scales and speeds. …”

Steerable parametric loudspeaker with preprocessing methods by Gan, Woon-Seng, Shi, Chuang.

“…Firstly, the relation between the phases of the primary waves and the difference frequency wave is explored to prove the feasibility of achieving a broadband steerable sound beam from the parametric loudspeaker with preprocessing methods. Secondly, based on the derived relation, the beamsteering structure is proposed. …”

Simulation analysis and scheme optimization of energy consumption in public buildings by Liu, Yang, Zou, Shiqing, Chen, Hongyu, Wu, Xianguo, Che, Wenman

“…First, a simulation model is constructed by using the energy consumption simulation analysis method, and the reliability of the model is verified by a comparison with the actual energy consumption. Second, based on the model, the thermal design parameters of six building envelope structures, including the external wall heat transfer coefficient, are analyzed in the order of energy-saving sensitivity. …”

Battling against protocol fuzzing: protecting networked embedded devices from dynamic fuzzers by Liu, Puzhuo, Zheng, Yaowen, Sun, Chengnian, Li, Hong, Li, Zhi, Sun, Limin

“…First, we design three adversarial primitives–delay, fake coverage, and forged exception–to break the fundamental mechanisms on which fuzzing relies to effectively find vulnerabilities. Second, based on our observation that inputs from normal users consistent with the protocol specification and certain program paths are rarely executed with normal inputs, we design static and dynamic strategies to decide whether to activate the adversarial primitives. …”

Efficient real-time coding-assisted heterogeneous data access in vehicular networks by Ali, G. G. Md. Nawaz, Noor-A-Rahim, Md., Rahman, Md. Ashiqur, Samantha, Syeda Khairunnesa, Chong, Peter Han Joo, Guan, Yong Liang

“…Due to ignoring the impact of heterogeneous data items in decoding, the conventional coding does not achieve expected performance in accessing data items with diverse size. Secondly, based on our observations, for efficiently serving heterogeneous data items, we have proposed a dynamic threshold based coding-assisted real-time data broadcast approach called EDF. …”
