This paper introduces a new model of prosodic typology by adding a parameter called macro-rhythm to the two known prosodic parameters, types of prominence marking (head, head/edge, edge) and word prosody (stress, tone, lexical pitch accent). Macro-rhythm is a tonal rhythm (a sequence of H/L alternation) in an Intonation Phrase. It captures similarities and differences across languages in terms ...

We study theoretically the bulk modulus (inverse of the compressibility) of a suspension of charged objects (macro-ions), making use of a cell model to account for the finite density of macro-ions. The diffuse layer of charged micro-species around a macro-ion is described by a generic local density functional theory. Within this general framework, we obtain the condition for a positive bulk mod...

We investigated the feasibility of the coexistence of CDMATDD micro cells under a CDMA-FDD macro cell network with both sharing the same frequency band. A dynamic channel allocation (DCA) algorithm decides on the basis of mutual interference which FDD band is to use for the micro cell TDD channel. On the assumption of giving the macro cell higher priority we investigated the lower bound probabi...

This paper presents a comprehensive characterization study on the exploitable memory value reuse present in programs. We compare three reuse schemes: store value reuse, loaded value reuse, and macro data reuse [12], [13]. Macro data reuse, enabled by macro data loads, capitalizes on under-utilized cache port bandwidth and makes use of the spatial locality found in port-wide macro data. Using a ...

The hierarchical macro/femto cell based BWA networks are observed to be quite promising for mobile operators as it improves their network coverage and capacity at the outskirt of the macro cell. However, this new technology introduces increased number of macro/femto handoff and wastage of electrical energy which in turn may affect the system performance. Users moving with high velocity or under...

This paper describes an algorithm to cluster and segment sequences of low-level user actions into sequences of distinct high-level user tasks. The algorithm uses text contained in interface windows as evidence of the state of user–computer interaction. Window text is summarized using latent semantic indexing (LSI). Hierarchical models are built using expectation–maximization to represent users ...

Air traffic system is analyzed from the aspects of system's attributes internal operating mechanisms and external behaviors. A hybrid air traffic simulation model described by the combination of discrete event and continuoustime models is proposed. The simulation model uses Agent-based techniques to describe micro behaviors of the air traffic individuals and integrates micro behaviors into dyna...

Using the example of CarboMoG, the Carbon Flow Model of Germany, structures and processes for process-based, macro-economic material flow models were analyzed. The aim is to create a toolbox, which can be used to assemble models of this kind from building blocks, to parameterize and calculate a model, and then to use the model for analysis tasks. It was investigated whether and how toolkits exi...

This paper presents a regime-switching Nelson–Siegel term structure model with macro factors and introduces a Markov chain Monte Carlo procedure to estimate the model. We find that regime shifts are important for understanding the interaction between the yield curve and economic activity. We also find that two regimes are closely related to the business cycle and monetary policy. Finally, we fi...
