Anisotropic diiusion has been extensively used as an eecient nonlinear ltering technique for simultaneously performing contrast enhancement and noise reduction, and for deriving consistent scale-space image descriptions. In this paper, we present a general study of anisotropic diiusion schemes based on diierential group-invariant representations of local image structure. We show that the local ...

The convolutional interleaver technique is used in telecommunication applications such as SDH and PDH radio systems, GSM and UMTS mobile communication systems, and point-tomultipoint radio systems to protect transmission channels from noise. On the transmit side, the convolutional interleaver parallelizes serial input data into N-bit words and shifts the data word through N delay lines. The del...

This paper concerns the domain of Supply Chain Network Infrastructure (SCNI) usually observed in the multimodal transportation systems such as Multimodal Passenger Transport Systems supported by lines of buses, trains, etc., and focuses on the scheduling problems encountered in these systems. SCNI can be modeled as a network of lines providing cyclic routes for particular kinds of stream-like m...

  The study seeks to address the importance of urban stream ecosystems from the perspective of urban ecology, human health and social well-being in the context of urban planning. The case study area is Paveh stream in the City of Paveh. The data from the case study area were gathered from questionnaire, existing scientific and library studies and by conducting interviews with residents and auth...

We report a study of the spectra and structure of the accretion disk of the dwarf nova V2051 Ophiuchi while the star was in an unusual faint brightness state during 1996. The differences between the UV resonant lines and continuum disk surface brightness distributions indicate a vertically extended disk with the emission from these lines arising from the upper atmospheric layers. Distinct emiss...

To determine the effect of development and environment on fin growth, we measured fin lengths of juvenile Atlantic salmon (Salmo salar) from two hatcheries (August, October and April–May), stream-reared fish (July and October) stocked as fry into two tributaries, and smolts from the main stem of the Connecticut River (May). For stream-reared parr, there was a linear relationship between the dor...

To cope with the growing demand for transportation on railway system, accurate, robust, and high-frequency positioning is required to enable a safe efficient utilization of existing infrastructure. As basis localization system we propose complete on-board mapping pipeline able map robust meaningful landmarks, such as poles from power lines, in vicinity vehicle. Such are good candidates reliable...
