Optimization of content-based image indexing and retrieval (CBIR) algorithms is a complicated and time-consuming task since each time a parameter of the indexing algorithm is changed, all images in the database should be indexed again. In this paper, a novel evolutionary method called evolutionary group algorithm (EGA) is proposed for complicated time-consuming optimization problems such as fin...

In scientific workflow systems, it is critical to ensure the timely completion of scientific workflows. Therefore, temporal constraints, as a type of QoS (Quality of Service) specification, are usually required to be managed in scientific workflow systems. Specifically, temporal constraint management includes two basic tasks: setting temporal constrains at workflow build time and updating tempo...

A comparison between two known strategies of modeling lap joint interfaces, namely, zero-thickness and thin layer interface theories and their associated updating procedures, is made. Finite element...

A wireless sensor integrates a radio to facilitate the exchange of data by wireless communications. In recent years, wireless sensors have rapidly matured with current platforms offering performance levels on par with traditional tethered sensors. The elimination of extensive wiring typical of tethered monitoring systems keeps the cost of wireless monitoring systems low. In addition to the incl...

Use of statistical classi cation methods in symbol recognition requires the speci cation of a number of model parameters Such parameters are usually ob tained from a training set This paper describes meth ods for improving parameter estimates obtained from a training set The improvement is made by us ing new observations for updating the parameter es timates The class membership of these new ob...

In this paper, a complete industrial validation of a recently published scheme for on-line adaptation of the control updating period in Model Predictive Control is proposed. The industrial process that serves in the validation is a cryogenic refrigerator that is used to cool the supra-conductors involved in particle accelerators or experimental nuclear reactors. Two recently predicted features ...

Approximation computation is a critical step in rough sets theory used in knowledge discovery and other related tasks. In practical applications, an information system often evolves over time by the variation of attributes or objects. Effectively computing approximations is vital in data mining. Dominance-based rough set approach can handle information with preference-ordered attribute domain, ...

When one moves, the spatial relationship between oneself and the entire world changes. Spatial updating refers to the cognitive process that computes these relationships as one moves. In two experiments, we tested whether spatial updating occurs automatically for multiple environments simultaneously. Participants turned relative to either a room or the surrounding campus buildings and then poin...

The brain can use multiple reference frames to code line orientation, including head-, object-, and gravity-centered references. If these frames change orientation, their representations must be updated to keep register with actual line orientation. We tested this internal updating during head rotation in roll, exploiting the rod-and-frame effect: The illusory tilt of a vertical line surrounded...
