The purpose of this paper is to construct a mode! of actions ar,d events suited to reasoning about domains involving multiple agents or dynamic environments. A mode! is constructed that provides for simultaneous action, and the kind of facts necessary for reasoning about such actions are described. A model-bssed foul O~~Z~J~J~OIC.T is introduced to describe how actions affect the world. No fram...

The ability to repair damage spontaneously, which is termed self-healing, is an important survival feature in nature because it increases the lifetime of most living creatures. This feature is highly desirable for rechargeable batteries because the lifetime of high-capacity electrodes, such as silicon anodes, is shortened by mechanical fractures generated during the cycling process. Here, inspi...

In this paper we present a novel laminate parametrization technique for layered composite structures that can handle problems in which the ply angles are limited to a discrete set. In the proposed technique, the classical laminate stiffnesses are expressed as a linear combination of the discrete options and design-variable weights. An exact `1 penalty function is employed to drive the solution ...

In this paper a novel automated design procedure based on the integration of a full wave Finite Element Analysis (FEA) and a topology design method employing Sequential Linear Programming (SLP) is introduced. The employed topology design method is the Solid Isotropic Material with Penalization (SIMP) technique which is formulated as a general non-linear optimization problem. SLP is used to solv...

Mechanical properties of products produced with the Fused Deposition Modeling (FDM) process are known to be dependent on bead direction, especially when short fiber reinforcement is added to the polymer filament feedstock. As a result, the structural performance of fiber-filled FDM parts is expected to be improved by simultaneously computing preferred deposition directions while optimizing the ...

The rotator type of optical modulating component modulator requires a planar angular rotator to control different angles for modulating the dissimilar light. If simply using the S-shape beam to behave a pin-joint, the rotator angle will be limited. The design target accordingly needs to maximize the range of output angle for satisfying the prescribed linear output positions or can be a sort of ...

In traditional document clustering models, a document is considered as a bag of words. In this paper we present a new method for generating feature vectors, using the sentence fragments that are called logical terms and statements, in PLIR system. PLIR is a Knowledge-Based Information system based on the theory of the Plausible Reasoning. We have conducted a number of experiments using OHSUMED ...

Highly flexible structures (springs) can be found in many precise devices, such as small actuators of optical disc drive and mobile cameras. A good configuration design is crucial for correct operation of these devices. In this case, optimization techniques can be applied to design of these flexible structures, aiming to reduce development time and costs. Remarkably, the design of these structu...
