We propose a method that combines acoustic-phonetic knowledge with support vector machines for segmentation of continuous speech into five classes vowel, sonorant consonant, fricative, stop and silence. We show that by using a probabilistic phonetic feature hierarchy, only four classifiers are required to recognize the five classes. Due to the probabilistic nature of the hierarchy, the method o...

The new methodology for software development is introduced and applied to an accounting system. The new method is called the incrementally modular abstraction hierarchy (IMAH). IMAH has an abstraction hierarchy from abstract to concrete levels. Invariants defined on an abstract level are kept on a concrete level, which allows adding modules incrementally on each hierarchical level and avoiding ...

We present PPC (Plan Projection and Clustering), an algorithm that creates a plan hierarchy for case-based plan recognition systems. PPC is motivated by a desire to improve the response time of robots working in collaboration with humans. It projects the plans of a case base into a Euclidean space and iteratively clusters plans within that space, producing an abstraction hierarchy. Case retriev...

Controlling complex humanoid robots can involve a lot of competing paradigms that can be simplified by breaking down the control process into a hierarchy of tasks. For this project, we implemented one such controller, as introduced in [1], that uses a user-defined hierarchy of tasks to perform a required task. We tested this on tasks such as squatting and balancing on flat ground under disturba...

A new generation of information systems that integrates knowledge base technology with database systems is presented for providing cooperative (approximate and conceptual) query answering. Based on the database schema and application characteristics, data are organized into Type Abstraction Hierarchies (TAHs). The higher levels of the hierarchy provide a more abstract data representation than t...

CIF is a language designed for two purposes, namely as a specification language for hybrid systems and as an interchange format for allowing model transformations between other languages for hybrid systems. To facilitate the top-down development of a hybrid system and also to be able to express models more succinctly in the CIF formalism, we need a mechanism for stepwise refinement. In this pap...

Focusing on the problem of low computation efficiency in the process of tracking human 3D motion, an algorithm for Estimating 3D arm motion with Hierarchy Limb Model (HLM) is proposed. In our algorithm, the Hierarchy Limb Model (HLM) is proposed based on the human 3D skeleton model. Facilitated by graph decomposition, the arm motion state space, modeled by Hierarchy Limb Model (HLM), can be dis...

are fully compatible with the so-called Tri-Bimaximal (TB) mixing pattern which corresponds to a maximal θ23, an zero θ13 and a “magic” value of solar angle: sin 2 θ12 = 1/3. It is well known that the lepton mixing angles can be understood by a mechanism of vacuum misalignment in flavour space occurring in theories with non-abelian flavour symmetries [2]. Also the charged lepton mass hierarchy ...

A method of determining radiosity in an environment containing moving objects, is described. This method uses the hierarchical techniques of Hanrahan et al. to obtain a static solution. Hanrahan's techniques e ciently create a hierarchical meshing of the environments geometry, and create links from element to element based on the magnitude of the form-factor between the elements. These ideas ex...

Primate visual cortex is hierarchically organized. Bottom-up and top-down influences are exerted through distinct frequency channels, as was recently revealed in macaques by correlating inter-areal influences with laminar anatomical projection patterns. Because this anatomical data cannot be obtained in human subjects, we selected seven homologous macaque and human visual areas, and we correlat...
