Determination and prioritization of eco-park components for sustainable urban development

BACKGROUND AND OBJECTIVES: Environmental sustainability is an important program of the United Nations to achieve sustainable urban development. It is important to understand the complicated relationship between the urban ecosystem and the natural environment to solve the environmental problems of cities. Owing to its ecological origin, the establishment of ecological parks plays an essential role in sustainable urban development as it aims to support the spiritual needs of citizens, advocate the life of other species, and minimize the manipulation of nature. This study aims to identify and prioritize important ecological, physical, economic, and social criteria in the eco-park of north-central Iran. Due to its topographic features and specific climate, it provides different habitats for wildlife and has ability to protect biodiversity in the urban ecosystem.METHODS: There are currently intentions for biodiversity compensation in urban planning due to public opinion and species extinction problems. However, scarce studies are available to reinforce this fundamental concept in urban management. This study aimed to determine and prioritize Alborz eco-park components in north-central Iran. In this research, the indicators were selected by fuzzy Delphi, using multivariate decision-making, entropy technique, and TOPSIS. FINDINGS: Based on the TOPSIS method, among environmental-ecological criteria, the highest rank belonged to the ex situ conservation of animals in the urban climate and biodiversity enhancement (relative closeness to ideal solution = 0.621). Eco-park establishment along the Chalus road and Hemmat superhighway was the design and physical criterion with the highest score (relative closeness to ideal solution = 0.696). From the socio-economic view, increasing the understanding of human-nature unity was the highly scored criterion (relative closeness to ideal solution = 0.767).CONCLUSION: The eco-Park is not only about conservation but also about large-scale restoration of nature. The implementation of this new generation of parks in response to local environmental concerns regarding location, physical aspects, design, and wildlife conservation will help transition to sustainable urban development. The north-central eco-park of Iran can be used as a model for the development of sustainable urban ecosystems

Cutting tool tracking and recognition based on infrared and visual imaging systems using principal component analysis (PCA) and discrete wavelet transform (DWT) combined with neural networks

The implementation of computerised condition monitoring systems for the detection cutting tools’ correct installation and fault diagnosis is of a high importance in modern manufacturing industries. The primary function of a condition monitoring system is to check the existence of the tool before starting any machining process and ensure its health during operation. The aim of this study is to assess the detection of the existence of the tool in the spindle and its health (i.e. normal or broken) using infrared and vision systems as a non-contact methodology. The application of Principal Component Analysis (PCA) and Discrete Wavelet Transform (DWT) combined with neural networks are investigated using both types of data in order to establish an effective and reliable novel software program for tool tracking and health recognition. Infrared and visual cameras are used to locate and track the cutting tool during the machining process using a suitable analysis and image processing algorithms. The capabilities of PCA and Discrete Wavelet Transform (DWT) combined with neural networks are investigated in recognising the tool’s condition by comparing the characteristics of the tool to those of known conditions in the training set. The experimental results have shown high performance when using the infrared data in comparison to visual images for the selected image and signal processing algorithms

Effects of landscape matrix on population connectivity of an arboreal mammal, Petaurus breviceps

Article first published online: 25 AUG 2015Ongoing habitat loss and fragmentation is considered a threat to biodiversity as it can create small, isolated populations that are at increased risk of extinction. Tree-dependent species are predicted to be highly sensitive to forest and woodland loss and fragmentation, but few studies have tested the influence of different types of landscape matrix on gene flow and population structure of arboreal species. Here, we examine the effects of landscape matrix on population structure of the sugar glider (Petaurus breviceps) in a fragmented landscape in southeastern South Australia. We collected 250 individuals across 12 native Eucalyptus forest remnants surrounded by cleared agricultural land or exotic Pinus radiata plantations and a large continuous eucalypt forest. Fifteen microsatellite loci were genotyped and analyzed to infer levels of population differentiation and dispersal. Genetic differentiation among most forest patches was evident. We found evidence for female philopatry and restricted dispersal distances for females relative to males, suggesting there is male-biased dispersal. Among the environmental variables, spatial variables including geographic location, minimum distance to neighboring patch, and degree of isolation were the most important in explaining genetic variation. The permeability of a cleared agricultural matrix to dispersing gliders was significantly higher than that of a pine matrix, with the gliders dispersing shorter distances across the latter. Our results added to previous findings for other species of restricted dispersal and connectivity due to habitat fragmentation in the same region, providing valuable information for the development of strategies to improve the connectivity of populations in the future.Mansoureh Malekian, Steven J.

Runoff simulation using SWAT model and SUFI-2 algorithm (Case study: Shafaroud watershed, Guilan Province, Iran)

Reliable estimates of runoff are required as a part of the information sets that help watershed managers make informed decisions on water resources planning and management. This study was carried out in Shafaroud watershed located in the north of Iran. In order to achieve the best runoff simulation in the study area, first rainfall data of four stations during 1998 to 2011 were collected and combined with other maps of the study area, such as Digital Elevation Model (DEM), land use and soil as input data in the form ofSoil and Water Assessment Tools (SWAT) model. After running the model, the Sequential Uncertainty Fitting (SUFI-2) algorithm in SWAT calibration and uncertainty program (SWAT-CUP) were used to evaluate the data uncertainty and the most accurate simulation. The first three years (1998-2000) of rainfall data for warm-up and the next 7 years (2001-2007) for the calibration and final 4 years (2008-2011) were used for the validation period. Finally, with multiple simulations, the uncertainty of the parameters was assessed with P-factor, R-factor, R 2 and NS coefficients. The results of validation period (R ^2=0.85, NS=0.74) confirmed the potential of SUFI-2 algorithm of SWAT-CUP program for simulating runoff data in the study area
