The ordinary GIS systems use command line, menu or window interface, which are difficult for a naïve user to use. In this paper, SNePS (the Semantic Network Processing System) is used to represent geographic spatial knowledge. An intelligent naturallanguage interface between ArcView and SNePS (the Semantic Network Processing System) was implemented. The interface will accept the input command a...

in this study, several data-driven techniques including system identification, adaptive neuro-fuzzy inference system (anfis), artificial neural network (ann) and wavelet-artificial neural network (wavelet-ann) models were applied to model rainfall-runoff (rr) relationship. for this purpose, the daily stream flow time series of hydrometric station of hajighoshan on gorgan river and the daily rai...

We present a joint relay and radio interface selection algorithm with packet deadline under limited power usage in multi-interface sensor networks. We find route optimization techniques in multi-interface networks: 1) selecting the most conservatively lowest-power interface to guarantee timely transmission considering the remaining hops to destination, and 2) searching detouring paths when the ...

Modern home theater systems require users to control various devices simultaneously including a TV, audio equipment, DVD and video players, and a receiver. To perform the requested user functions in this situation, the user is required to know the functions and positions of the buttons on several remote controls. Users will become more confused if a ubiquitous home environment, which contains m...

Until now, network applications are developed based on the TCP/IP network model which is intrinsically based on stationary wired networks. Here, the socket interface is the most widely used API (application program interface). However, due to widely available mobile wireless computers, location-based network services are required to be developed, e.g. location-based advertisement and query for ...

In this paper, we obtain the optimal number of interfaces/channels in wireless mesh networks by simulation. The simulation study is done in static multi-channel multi-interface environment. When many nodes use a single interface/channel, collisions of RTS/CTS result in network performance degradation. To avoid such degradation and reduce interference among adjacent nodes, use of multi-interface...

The paper describes the realisation of a Spread Spectrum Network Analyser using appropriate software to control a PC interface card, like a soundcard. The software generates a digitised time waveform consisting of a Spread Spectrum signal containing a number of equal amplitude spectral components. The interface card converts this waveform to an analogue signal, which is then passed through the ...

Because of user demands for better quality of service, network-aware applications have been of increasing necessity. To enable more control, the end-host operating system (OS) is the entity responsible for providing appropriate service level and API to user applications. However, most of the work in this area remains domain-specific and without a generalizable scheme for providing network contr...

Reducing the energy consumption of PCs is becoming increasingly important with rising energy costs and environmental concerns. Sleep states such as S3 (suspend to RAM) save energy, but are often not appropriate because ongoing networking tasks, such as accepting remote desktop logins or performing background file transfers, must be supported. In this paper we present Somniloquy, an architecture...

copper–silver bimetallic strips were produced by cold roll welding process and were treated by diffusion annealing in the temperature range 250–800 ?c. the interface bonding strength was determined by bending and peeling tests, resistance, conductivity and micro hardness profiles were determined and microstructure in the interface region was observed by optical microscope. electrical resistance...
