For the planning of large infrastructure projects, such as tunnelled inner-city carriageways, completely different scales have to be considered – ranging from the scale of several kilometres for the general routing of the carriageway down to centimetre scale for the detailed planning of track nodes. However, today’s planning software hardly supports multi-scale approaches. The paper presents a ...

Abstract. Natural populations of Carpinus orientalis Mill. Shrub lands occur mainly in high and middle altitudes of the Hyrcanian forests, N. Iran, particularly on steep rocks and forest outcrops. There are some discrepancies on the intra-specific delimitation of this important woody species. The aim of the current study was to examine the anatomical variation of stems and leaves of sixteen pop...

evaluation of communication abilities in the elderly is crucial for activities which will be performed to improve their quality of life. a valid and reliable questionnaire is needed for assessing communication abilities. we aimed to translate and validate the speech, spatial, and qualities of hearing scale (ssq) in iran. the forward-backward procedure was applied to translate the questionnaire ...

introduction: 17&beta-estradiol; modulates nociception by binding to the estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and gabaa receptors. in addition to its autonomic functions, paragigantocellularis lateralis (lpgi) is involved in the pain modulation, too. the aim of the current study was to investigate the involvement of the membr...

The wind loads considerably influence lightweight spatial structures. An example of spatial structures is scallop domes that contain various configurations and forms and the wind impact on a scallop dome is more complex due to its additional curvature. In our work, the wind pressure coefficient (Cp ) on the scallop dome surface is studied numerically and experimentally. Firstly, the programming...

This dissertation addresses the problems of recognizing textures, objects, and scenes in photographs. We present approaches to these recognition tasks that combine salient local image features with spatial relations and effective discriminative learning techniques. First, we introduce a bag of features image model for recognizing textured surfaces under a wide range of transformations, includin...

[1] The complex interactions between plants, soils, and climates in semiarid ecosystems make it difficult to define specific ecohydrological optimization mechanisms that underlie observed spatiotemporal patterns of vegetation structure. There remains a clear need to develop conceptual models that are capable of interpreting and predicting spatial pattern formation in savannas (and similar dry w...

Current advanced lithography processes are based on a Critical Dimension (CD) budget of 10nm or less with errors caused by exposure tool, wafer substrate, wafer process, and reticle. As such, allowable CD variation across wafer becomes an important parameter to understand, control and minimize. Three sources of errors have an effect on CD Uniformity (CDU) budget, run-to-run (R2R), wafer-to-wafe...

In this thesis, I studied spatial and temporal variability of macroinvertebrate assemblages of boreal streams. The main objectives were (i) to characterize macroinvertebrate assemblage types across large geographical extents, and to assess the utility of assemblage types and landscape and stream type classifications as the basis of stream bioassessment and conservation programs (ii, iii). I als...
