Thermal expansion of materials is fundamental practical relevance and arises from an interplay several material properties. For nanocrystalline materials, accurate measurements thermal based on high-precision reference dilatometry allow inferring phenomena taking place at internal interfaces such as vacancy annihilation grain boundaries. Here we report obtained for a severely deformed 316L aust...

FinFET memory is widely used in various semiconductor products due to its good read/write margin, lower power consumption, and faster driving speed. However, the forked 3D physical structure increased density of storage are very susceptible manufacturing defects, which may cause functional logic faults that different from traditional planar CMOS memories. Therefore, it critical explore an effec...

New memory technologies and processes introduce new defects that cause previously unknown faults. Dynamic faults are among these new faults; they can take place in the absence of the traditional static faults. This paper describes the concept of dynamic faults, based on the fault primitive concept. It further shows, based on industrial test results, the importance of such faults for the new mem...

Testing costs can be reduced through automated unit test generation. An important benchmark for such tools is their ability to detect real faults. Fault databases, such as Defects4J, assist in this task. The Guava project—a collection of Java libraries from Google—offers an opportunity to expand such databases with additional complex faults. We have identified 11 faults in the Guava project, ad...

abstract the study of natural disasters is one of the most important primary principles for the growth of developing cities and the development of infrastructures. to this end, evaluating geodynamic activities using morphological data is considered one of the most pivotal applied methods. in this study, it was tried to detect active faults in yazd province using desert studies and remote sensin...

this paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. the methodology is based on a modified sliding mode observer (smo) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. the faults are reconstructed using the equivalent output error i...

Time redundant execution of tasks and comparison of results is a well-known technique for detecting transient faults in computer systems. However, time redundancy is also capable of detecting permanent faults that occur during or between the executions of two task replicas, provided the faults affect the results of the two tasks in different ways. In this paper, we derive an expression for esti...

In this paper, we consider fault detection, isolation and reconstruction problem for descriptor systems with actuator faults and sensor faults, respectively. When actuator faults exist in the system, the fault detection and isolation (FDI) problem is solved through an unknown input observer regarding remaining faults excluded a specified fault as unknown inputs. Whereas, in existing sensor faul...

In this paper we study the ability of array-based networks to tolerate worst-case faults. We show that an N × N two-dimensional array can sustain N1− worst-case faults, for any fixed > 0, and still emulate T steps of a fully functioning N × N array in O(T + N) steps, i.e., with only constant slowdown. Previously, it was known only that an array could tolerate a constant number of faults with co...
