In this paper, we present two novel memetic algorithms (MAs) for gene selection. Both are synergies of Genetic Algorithm (wrapper methods) and local search methods (filter methods) under a memetic framework. In particular, the first MA is a Wrapper-Filter Feature Selection Algorithm (WFFSA) fine-tunes the population of genetic algorithm (GA) solutions by adding or deleting features based on uni...

With increasing size and complexity of Grids manual diagnosis of individual application faults becomes impractical and timeconsuming. Quick and accurate identification of the root cause of failures is an important prerequisite for building reliable systems. We describe a pragmatic model-based technique for application-specific fault diagnosis based on indicators, symptoms and rules. Customized ...

Continual advances in the manufacturing processes of integrated circuits provide designers the ability to create more complex and denser architectures and increased functionality on a single chip. The increased usage of embedded cores necessitates a core-based test strategy in which cores are also tested separately. The IEEE P1500 proposed standard for Embedded Core Test (SECT) is a standard un...

Web index recommendation systems are designed to help internet users with suggestions for finding relevant information. One way to develop such systems is using the multi-instance learning (MIL) approach: a generalization of the traditional supervised learning where each example is a labeled bag that is composed of unlabeled instances, and the task is to predict the labels of unseen bags. This ...

Wrappers export the schema and data of existing heterogeneous databases and support queries on them. In the context of cooperative information systems, we present a exible approach to specify the derivation of object-oriented export databases from local relational databases. Our export database derivation consists of a set of extent derivation structures which de-nes the extent and deep extent ...

The use of Commercial Off-The-Shelf (COTS) software products as components of large-scale systems has become more and more pervasive. One of the interesting questions that has arisen is "Can you build secure applications using insecure components?" We have been investigating ways to protect data that is shared between two or more independent, insecure applications. Our initial attempts to accom...

The purpose of this thesis project is to develop an XTM (XML Topic Maps) wrapper, called XTMWrapper, for the functional and object-oriented DBMS Amos II so that XTM files can be accessed through Amos II using its query language, AmosQL. The wrapper can be used as a database loader for XTM files. The wrapper parses XTM files, translates them into an Amos II data representation, and populates the...

The midline glia are specialized, nonneuronal cells at the midline of the Drosophila central nervous system (CNS). During development, the midline glia provide guidance cues for extending axons. At the same time, they migrate and help separate the two axon commissures. They then wrap around and ensheath the commissural axons. In many segments, a few of the glia do not enwrap the axons, and thes...

This paper describes the Wrapper Facade pattern. The intent of this pattern is to encapsulate low-level functions and data structures with object-oriented (OO) class interfaces. Common examples of the Wrapper Facade pattern are class libraries like MFC, ACE, and AWT that encapsulate native OS C APIs, such as sockets, pthreads, or GUI functions. Programming directly to native OS C APIs makes net...

For adequate treatment of patients, it is important that the accurate and reliable algorithm is developed for construction of diagnosis system. Gene expression data from DNA microarray are individualized and are useful in the diagnosis and prognosis of diseases. However, to conduct analysis, it is necessary to select marker genes that are strongly related to diagnosis or prognosis of disease be...
