The research project Simulating intonational varieties of Swedish (SIMULEKT) aims to gain more precise and thorough knowledge about some major regional varieties of Swedish: South, Göta, Svea, Gotland, Dala, North, and Finland Swedish. In this research effort, the Swedish prosody model and different forms of speech synthesis play a prominent role. The two speech databases SweDia 2000 and SpeechDat constitute our main material for analysis. As a first test case for our prosody model, we compared Svea and North Swedish intonation in a pilot production-oriented perception test. Näi{dotless}ve Swedish listeners were asked to identify the most Svea and North sounding stimuli. Results showed that listeners can differentiate between the two varieties from intonation only. They also provided information on how intonational parameters affect listeners' impression of Swedish varieties. All this indicates that our experimental method can be used to test perception of different regional varieties of Swedish.

Systems of polynomial equations over an algebraically-closed field K can be used to concisely model many combinatorial problems. In this way, a combinatorial problem is feasible (e.g., a graph is 3-colorable, hamiltonian, etc.) if and only if a related system of polynomial equations has a solution over K. In this paper, we investigate an algorithm aimed at proving combinatorial infeasibility based on the observed low degree of Hilbert's Nullstellensatz certificates for polynomial systems arising in combinatorics and on large-scale linear-algebra computations over K. We report on experiments based on the problem of proving the non-3-colorability of graphs. We successfully solved graph problem instances having thousands of nodes and tens of thousands of edges.

Muskel: A skeleton library supporting skeleton set expandability

Scalable Computing 2007年第4期8卷 325-341页

programming models based on algorithmic skeletons promise to raise the level of abstraction perceived by programmers when implementing parallel applications, while guaranteeing good performance figures. At the same time, however, they restrict the freedom of programmers to implement arbitrary parallelism exploitation patterns. In fact, efficiency is achieved by restricting the parallelism exploitation patterns provided to the programmer to the useful ones for which efficient implementations, as well as useful and efficient compositions, are known. In this work we introduce muskel, a full Java library targeting workstation clusters, networks and grids and providing the programmers with a skeleton based parallel programming environment. muskel is implemented exploiting (macro) data flow technology, rather than the more usual skeleton technology relying on the use of implementation templates. Using data flow, muskel easily and efficiently implements both classical, predefined skeletons, and user-defined parallelism exploitation patterns. This provides a means to overcome some of the problems that Cole identified in his skeleton "manifesto" as the issues impairing skeleton success in the parallel programming arena. We discuss fully how user-defined skeletons are supported by exploiting a data flow implementation, experimental results and we also discuss extensions supporting the further characterization of skeletons with non-functional properties, such as security, through the use of Aspect Oriented programming and annotations. © 2007 SWPS.

Mirror-based systems are object-oriented reflective architectures built around a set of design principles that lead to reflective APIs which foster a high degree of reusability, loose coupling with base-level objects and whose structure and design corresponds to the system being mirrored. However, support for behavioral intercession has been limited in contemporary mirror-based architectures, in spite of its many interesting applications. This is due to the fact that mirror-based architectures only support explicit reflection, while behavioral intercession requires implicit reflection. This work reconciles mirrors with behavioral intercession. We discuss the design of a mirror-based architecture with implicit mirrors that can be absorbed in the interpreter, and mirages, base objects whose semantics are defined by implicit mirrors. We describe and illustrate the integration of this reflective architecture for the distributed object-oriented programming language AmbientTalk. © 2007 ACM.

Many parallel computing applications are used for simulation of complex engineering applications and/or for visualization. To handle their complexity, there is a need for raising the level of abstraction in specifying such applications using high level mathematical modeling techniques, such as the Modelica language and technology. However, with the increased complexity of modeled systems, it becomes increasingly important to use today's and tomorrow's parallel hardware efficiently. Automatic parallelization is convenient, but may need to be combined with easy-to-use methods for parallel programming. In this context, we propose to combine the abstraction power of Modelica with support for shared memory bulk-synchronous parallel programming including nested parallelism (NestStepModelica), which is both flexible (can be mapped to many different parallel architectures) and simple (offers a shared address space, structured parallelism, deterministic computation, and is deadlock-free). We describe NestStepModelica and report on first results obtained with a prototype implementation. © Springer-Verlag Berlin Heidelberg 2007.

On-line assessment system for English-Chinese translation

Journal of Shanghai Jiaotong University (science) 2007年第2期12 E卷 180-184页

On-line assessment of English-Chinese translation is a challenging task as it involves natural language processing. YanFa, an on-line assessment system for English-Chinese translation, is a pilot research project into scoring student's translation on-line. Based on the theory of translation equivalence, an algorithm called conceptual similarity matching was developed. YanFa can assess students' translation on-line timely, generate test papers automatically, offer standard versions of translation, and the scores of each sentence to students. The evaluation proves that YanFa is practical compared with the scores given by experts.

Speaker age is a speaker characteristic which is always present in speech. Previous studies have found numerous acoustic features which correlate with speaker age. However, few attempts have been made to establish their relative importance. This study automatically extracted 161 acoustic features from six words produced by 527 speakers of both genders, and used normalised means to directly compare the features. Segment duration and sound pressure level (SPL) range were identified as the most important acoustic correlates of speaker age. © Springer-Verlag Berlin Heidelberg 2007.

Considering the large amounts of data that is nowadays produced in the biochemistry (functional genomics) it is difficult to extract the information from the measurements. There is currently also a great interest in the development of novel analytical technologies for rapid screening of disease symptoms in pharmaceutical and clinical applications. Modeling and simulation can provide a useful help in understanding the relations of the measured substances and to minimize the need for measurements. The BioChem library presented here is the first free Modelica library available for mathematical modeling of biochemical processes. Three examples are shown to illustrate the library. First, a simple insulin model is presented. Then a simplified model of cholesterol together with simulations are shown. Next, a simple drug model together with parameter estimation in NONMEN are presented. The BioChem library allows for fast and end-user friendly modeling of biomedical systems. The graphical user interface provides graphics similar to that used in the description of metabolic pathways in biochemistry.

1st International Workshop on Equation-Based Object-Oriented languages and Tools, EOOLT 2007 - In Conjunction with the ECOOP 2007 Conference

This paper describes a new solution method applied to the problem initializing DAEs using the Modelica language. Modelica is primarily an object- oriented equ-tion-based modeling language that allows specification of mathematical models of complex natural or man-made systems. Major features of Modelica are the multidomain modeling capability and the reusability of model components corresponding to physical objects, which allow to build and simulate highly complex systems. However, initializing such models has been quite cumbersome, since initial equations have to be pro-vided at the system level, where the user needs to know details on the underlying transformation and index-reduction algorithms, that in general are applied to simulate a Modelica model.
