The paper discusses the modeling of “if possible" in requirements of the form “A and if possible B". We distinguish between two types of understanding: either i) A and B are requirements of the same nature and are viewed as constraints with different levels of priority, or ii) they are of different nature (only A induces constraint(s) and B is only used for breaking ties among items that are eq...

Piezoelectric materials play an increasingly important role in energy harvesters, sensors, and actuators. Flexible thin piezoelectric films have been demonstrated to provide advanced functionalities improved performances. However, the research on flexible inorganic has rarely systematically summarized. Here, we summarize recent advances films, focusing their structural designs, fabrication tech...

We describe a exible object recognition and modeling system (FORMS) which represents and recognizes animate objects from their silhouettes. This consists of a model for generating the shapes of animate objects which gives a formalism for solving the inverse problem of object recognition. We model all objects at three levels of complexity: (i) the primitives, (ii) the mid-grained shapes, which a...

Existing volatility models normally emphasize the behaviour of prices in a temporal sense and comparatively few studies have explicitly analysed spatial variation volatility. This paper proposes flexible model for squared returns using Box–Cox transformation that includes linear log-linear forms as special cases, thus providing unified framework simultaneously testing space-varying its function...

A major drawback of constant elasticity supply and demand systems, which are widely used in simulation models for applied policy analysis, is that they can’t be restricted to globally comply with certain conditions implied by economic theory. This paper compares constant elasticity systems to supply and demand systems derived from second order flexible functional forms (FFFs). Furthermore, supp...

Interconnected power system networks are multi loop structured. Settings determination of all over current and distance relays in such networks can be in different forms and complicated. The main problem is the determination of starting points i.e. the location of starting relays in the procedure for settings, which is referred to as break points. In this paper, a new approach based on graph th...

Most human-machine communication for information access through speech, text and graphical interfaces are mediated by forms – i.e. lists of named fields. However, deploying form-filling dialogue systems still remains a challenging task due to the effort and skill required to author such systems. We describe an extension to the OpenDial framework that enables the rapid creation of functional dia...
