This paper explores an efficient Medium Access Control protocol for carrying data traffic via satellite. The Combined Free/Demand Assignment Multiple Access (CFDAMA) protocol combines free assignment of data slots with demand assignment, providing a minimum delay of one round trip time at low loads and the statistical multiplexing gains of demand assignment at high loads. The delay/utilisation ...

The energy saving and emission reduction in thermal plant is complex, with the open, non-equilibrium and interoperability features. In order to identifying the order parameters affecting plant system, a co-evolution model of energy saving and emission reduction in thermal power plant was built based on synergetic theory. According to the feathers of potential function based on mutation theory, ...

Informed by the expectancy-value and social cognitive theories of learning, the present study proposed a path model to investigate the impact of motivational beliefs as defined by listening self-efficacy, three types of goal orientations, and task value on self-regulation of Iranian EFL learners, in addition to the unique contribution of each to the variability in the listening comprehension sc...

1 Yonezawa is also a graduate student of Keio University, Graduate School of Media and Governance. ABSTRACT In this paper, we introduce our research challenges for creating new musical instruments using everyday-life media with intimate interfaces, such as the self-body, clothes, water and stuffed toys. Various sensor technologies including image processing and general touch sensitive devices a...

A major source of performance degradation in highperformance distributed applications has been attributed to poor end-to-end TCP performance. The root causes of poor TCP performance are difficult to isolate and diagnose, and the efficacy of tuning efforts are often difficult to gauge. This paper describes some sources of poor TCP performance, and describes a method to diagnose some of these pro...

The results of two experiments support the thesis that emotional perspective taking entails two judgments: a prediction of one’s own preferences and decisions in a diVerent emotional situation, and an adjustment of this prediction to accommodate perceived diVerences between self and others. Participants overestimated others’ willingness to engage in embarrassing public performances—miming (Expe...

We present aligned hierarchies, a novel solution to the dimension reduction problem, representing high-dimensional and noisy sequential data as a low-dimensional object that encodes relevant information. In this thesis, we motivate our presentation and discussion of aligned hierarchies through the lens of Music Information Retrieval (MIR), constructing aligned hierarchies by finding, encoding, ...

Heat exchangers are widely used in power engineering and industrial applications, many techniques such as coiled tube, surface tension devices, rough surfaces, extended surfaces have been investigated to enhancethermal performance and to minimize the cost and size of the heat exchanger equipment. One of the most important techniques is tube insert. In general,tube inserts can be classified into...
