In this paper, we propose a distributed and self-organizing communication mechanism for a wireless sensor network where a large number of sensor nodes are deployed. To accomplish periodic communication without any centralized controls, we adopt traveling wave phenomena of a pulse-coupled oscillator model by regarding sensor nodes as oscillators and emission of radio signals as firing. We consid...

We use the ‘‘magic TV’’ network with the maximum a posteriori (MAP) criterion to restore a space-dependent blurred image. This network provides a unique topological invariance mechanism that facilitates the identification of such space-dependent blur. Instead of using parametric modeling of the underlying blurred image, we use this mechanism to accomplish the restoration. The restoration is rea...

Vehicular networking is an emerging area of interest in the wireless networking community as well as in the transportation research community. Vehicular ad hoc networks (vanet) are distributed, self-organizing communication networks which progressed from traveling vehicles, and are thus characterized by very high speeds and limited degrees of freedom in node (vehicle) movement patterns. Differe...

Prototyping is a critical method for exploring, communicating and testing new concepts in an interactive system development process. However, the criteria used in prototype model evaluation often do not address the original project objectives and issues. To improve this situation, a prototyping specification mechanism with aspect models and scenarios created through the aspect models are introd...

We present a mechanism of unsupervised competitive learning and development of topology preserving self-organizing maps of spiking neurons. The information encoding is based on the precise timing of single spike events. The work provides a competitive learning algorithm that is based on the relative timing of the preand post-synaptic spikes, local synapse competitions within a single neuron and...

---------------------------------------------Abstract Recently, security of the computer systems becomes an important problem. Almost all computers use the password mechanism for the user authentication. But password mechanism has many issues. In this paper, we propose a kind of biometrics authentication method using the timings of key strokes of an identical simple phrase for all users. For th...

mission and sleep scheduling mechanisms for periodically gathering sensor data at a base station in wireless sensor networks. In our proposed mechanisms, we use a conventional self-organizing communication mechanism based on phase-locking in a pulse-coupled oscillator model to propagate sensor data from the edge of the network to the base station in order of hop counts from the base station. In...

The purpose of this study is to focus on the indicators related motivation in Work Mind, and organize concepts by Pile Sort experiments using sentences question items that compose each indicator. By polymerizing personal conceptual system Self-Organizing Map, map Mind with some degree completeness generality drawn. It expected will be a material for getting general picture treated as ruler when...

Polarized growth in eukaryotes requires polar multiprotein complexes. Here, we establish that selection and maintenance of cell polarity for growth also requires a dedicated multiprotein assembly in the filamentous bacterium, Streptomyces coelicolor. We present evidence for a tip organizing center and confirm two of its main components: Scy (Streptomyces cytoskeletal element), a unique bacteria...
