Yu-Fang Chen, Ondrej Lengal, Tony Tan, Zhilin Wu

2017 32nd Annual ACM/IEEE Symposium on Logic in Computer Science (LICS) > 1 - 12

2017 32nd Annual ACM/IEEE Symposium on Logic in Computer Science (LICS)

We propose a novel automata model over the alphabet of rational numbers, which we call register automata over the rationals (RA_ℚ). It reads a sequence of rational numbers and outputs another rational number. RA_ℚ is an extension of the well-known register automata (RA) over infinite alphabets, which are finite automata equipped with a finite number of registers/variables for storing values. Like in...

Jiuming Lv, Fangyi Hu, Quoc Dinh Cao, Renshu Yuan, more

Journal of Materials Engineering and Performance > 2017 > 26 > 3 > 1463-1474

Hydrostatic extrusion integrated with circular equal channel angular pressing has been previously proposed for fabricating AZ80 magnesium alloy tubes as a method to obtain high-strength tubes for industrial applications. In order to axial tensile strength, circumferential mechanical properties are also important for tubular structures. The tensile properties of AZ80 tubes have been previously studied;...

On temporal logics with data variable quantifications: Decidability and complexity

Fu Song, Zhilin Wu

Information and Computation > 2016 > 251 > C > 104-139

Although data values are available in almost every computer system, reasoning about them is a challenging task due to the huge data size or even infinite data domains. Temporal logics are the well-known specification formalisms for reactive and concurrent systems. Various extensions of temporal logics have been proposed to reason about data values, mostly in the last decade. Among them, one natural...

Feasibility of Motion Planning on Directed Graphs

Zhilin Wu, Stéphane Grumbach

Lecture Notes in Computer Science > Theory and Applications of Models of Computation > Contributed Papers > 430-439

Because of irreversibility of movements, motion planning on directed graphs is much more intricate than that on graphs. Recently we showed that the feasibility of motion planning on acyclic and strongly connected directed graphs can be decided in time O(nm) (n,m are respectively the number of vertices and arcs of the directed graph), but left the feasibility of motion planning on (general) directed...
