the present study has tried to accomplish an analysis of margaret atwood’s novels oryx and crake, and the year of the flood in the light of posthuman and cyborg theories. considering posthumanism as a critical reading of some notions of humanism focus of which in this thesis has been identity, new definitions for humanity and human identity are formed. haraway’s cyborg, as one possible new figu...
Flooding is responsible for substantial loss of life and economy. Flood mapping, the process of distinguishing flooded areas from non-flooded areas during and after a disaster, can be very useful in guiding first response resources in a disaster situation, and in assessing flood risk in future disaster scenarios. This paper involves the use of image segmentation methods and human guidance to pr...
Now floodwater spreading on aquifers is one of the suitable methods for control and efficient use flood and artificial feed groundwater in arid and semi-arid regions and determine appropriate locations with accuracy and required speed for floodwater spreading it is of utmost importance. In this study, were identified main criteria four, sub criteria eight and indicators 24 Criteria, sub criteri...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
Flood hydrograph preparation and estimation are considered a comprehensive information for soil and water managers and planners. While it is not simply possible preparing it for all watersheds. Therfore suitable flood hydrograph estimation and modeling seems to be necessary using available rainfall data. The study area is located in Kasilian representative watershed in Mazandaran province compr...
Rice is the most important food crop. With largest rain-fed lowland area in world, flooding considered as abiotic stress to rice production India. climate change, it expected that frequency and severity of floods will increase over years. These changes have a severe impact on agriculture livelihoods millions farmers flood affected region. There are numerous risk adaptation mitigation options av...
Flood is considered as a major threat among natural disasters in the world. This case becomes more important and has a higher risk in urban areas due to the existence of important uses. Therefore, to reduce damages resulted from flood, this phenomenon must be managed and planned using structural and non-structural approaches. Considering the development in Iran has been carried out in high risk...
the scientific community agrees that climate change is one of the greatest challenges that oursociety will have to face this century. indeed, the fourth report from the intergovernmental panel on climatechange (ippc) confirms the certitude of this phenomenon and its impacts, which can range from droughts tofloods, health problems and food shortages. the principal objective of this paper is to a...
Among the variety of method s used for estimating runoff in the watershed, the SCS method has universal applicability, so the main aim of this study is the calibration of SCS method and the creation of flood hydrograph. The HEC-HMS hydrologic (rainfall-runoff) model has been used for Idanak watershed flood estimation. Using the residual sum of squared minimization function”, calibration proce...
