GIS and remote-sensing-based urban-information system design and development: A case study for Kozlu, Zonguldak
Urban growth is inevitable over the next two decades. The bulk of this growth will take place in less developed countries. This growth presents a formidable challenge for urban planners and managers. In this context, we consider some of the ways urban planners can make use of the recent developments in Geographic Information Systems (GIS) and Remote-Sensing (RS) technology to respond to this challenge. GIS projects were...

Political legacy of South Africa affects the plant diversity patterns of urban domestic gardens along a socio-economic gradient
In recent years domestic gardens in urban areas have been extensively studied, but findings from developed and developing countries do not always correspond. The disparity is ascribed to differences in climate, culture and socio-economics. This study from South Africa analyzes plant diversity patterns along a steep, indirect socio-economic gradient in a single city. The segregation laws of the apartheid...

Spatial distribution and temporal change of old-growth forest: A case study in the Balci forest management unit, Turkey
Old-growth forests are considered as one of the important conservation targets in sustainable management of forest ecosystems. Stand parameters such as age, diameter at breast height, area, species mixture, canopy closure and snag volume per hectare are employed in estimating the value of the old-growth forests. This article is focused on the main stand parameters in determining potential old-growth forest...

Increase reliability for skin detector using backprobgation neural network and heuristic rules based on YCbCr
Skin detection is a popular image processing technique that has been applied in many areas such as video-surveillance, cyber-crime prosecution and unit-spam system. It is also considered as one of the most challenging problems in image processing. Despite being a well known technique in detecting human appearance within image, it faces several drawbacks when using colour as cue to detect skin. First, the...

One dimensional image processing for eye tracking using derivative dynamic time warping
In this paper, one dimensional image processing for eye tracking approach is presented using a low cost webcam. It was found that the algorithm is resistant to illumination variation and is able to track eyes of users with and without glasses in multiple orientations. The size and location of the region of interest (ROI), which contains both eyes, is adaptive. Derivative Dynamic Time Warping (DDTW) is chosen...

Optimization of the process parameters of synthesis of oligomeric procyanidins imprinted polymer
Molecularly imprinted polymers (MIP) are tailor-made polymers with high selectivity for the template molecule. This selectivity arises from the synthetic procedure followed to prepare the MIP. In this work, the influence of process parameters on the preparation of oligomeric procyanidins (OPC) imprinted polymers was presented. In the procedure of polymerization, OPC (90 mg) was used as the template molecule,...

Determining the effects of Degirmendere River on Trabzon Harbor after construction of Black Sea highway on Black Sea coast
Alluvium, which is composed of sand, rubble, stone and soil, is carried by stream and rivers into harbors, bays and dams. Transported alluvium is accumulated as the time went by at the bottom and causes decrease in depth level. Degirmendere watershed receives lasting and heavy precipitation. This precipitation occasionally causes overflowing of the Degirmendere Stream and therefore causes flood and heavy...

Automatic tissue arrayer and method for reliable and rapid construction of tissue microarray (TMA) blocks
Tissue microarray (TMA) technology is generally used in cancer research for recognizing tumors, and for identifying new diagnostics and therapeutics. Using traditional methods, such as manual and semi-automatic arrayer, to construct TMA blocks may result in missing tissue cores on the TMA slide due to weak compactness between cores and paraffin wax. Furthermore, relying on human eyes for manual alignment is...
