A new methodology for evaluating coastal scenery: fuzzy logic systems

Ergin, Ayşen
Micallef, A
Williams, AT
Coastal scenery evaluated by utilization of selected landscape components was subjected to a fuzzy logic systems approach. Twenty-six top-rated parameters were identified from a literature search/questionnaire surveys carried out in Malta, Turkey and the UK and coastal scenery investigated at 57 sites. A coastal scenic evaluation checklist system was finalized and consisted of assessment parameters based on a five-point scale ranging from low to high attribute values. Coastal user parameter preferences and priorities for these parameters were obtained by a questionnaire perception study (n=270) given to both locals and visitors. Assessment parameter weights were calculated from this public perception survey via matrices relating to the selected landscape components. For each of the 26 parameters, a membership-graded matrix was established to counteract potential errors in assigning grades to the parameters when one has to give a unique number to the attribute value. To overcome subjectivity and quantify uncertainty, fuzzy logic mathematical methodology was adopted to this checklist approach. This enabled an Evaluation Index (D) value to be calculated, establishing a 5-class evaluation system. Class 1 scenery (extremely attractive natural site) had 0 values > 0.85; Class 2, between 0.85 and 0.65; Class 3, between 0.65 and 0.4; Class 4, between 0.4 and zero; Class 5 (very unattractive, intensively developed urban) below zero.


A new approach to neural trip distribution models: NETDIM
Tapkin, Serkan; Akyilmaz, Ozdemir (Informa UK Limited, 2009-01-01)
This paper develops and presents a new neural network approach to model trip distribution, which is one of the important phases of conventional four-step travel demand modelling. The trip distribution problem has been investigated using back-propagation artificial neural networks in a number of studies and it was concluded that back-propagation artificial neural networks underperform when compared to traditional models. Such underperformance is due to the thresholding of the linearly combined inputs by util...
Coastal scenic evaluation by application of fuzzy logic mathematics
Uçar, Barış; Ergin, Ayşen; Department of Civil Engineering (2004)
Coastal scenery evaluated by utilization of selected landscape components was subject to fuzzy logic system approach. Based on this methodology, coastal areas were grouped into five classes using the evaluation index D giving the overall result of scenic assessment over the attributes. Within the methodology, public perception surveys from Turkey, UK, Malta, and Croatia were used as a tool for environmental perception in the methodology. The results of the public perception surveys were utilized to obtain t...
A Cloud Removal Algorithm to Generate Cloud and Cloud Shadow Free Images Using Information Cloning
Kalkan, Kaan; Maktav, M. Derya (Springer Science and Business Media LLC, 2018-08-01)
One of the main problems of optical remote sensing is clouds and cloud shadows caused by specific atmospheric conditions during data acquisition. These features limit the usage of acquired images and increase the difficulty in data analysis, such as normalized difference vegetation index values, misclassification, and atmospheric correction. Accurate detection and reliable cloning of cloud and cloud shadow features in satellite images are very useful processes for optical remote sensing applications. In thi...
Using feature models for reusability in agile methods
Jedyk, Marcin; Doğru, Ali Hikmet; Department of Computer Engineering (2011)
The approach proposed in this thesis contributes to implementing source code reuse and re-engineering techniques for agile software development. This work includes an introduction to feature models and some of the Feature Oriented Software Development (FOSD) practices to achieve a lightweight way of retrieving source code. A Feature model created during the course of following FOSD practices serves as an additional layer of documentation which represents the problem space for the developed application. This...
An critique of housing classes approach : the case of Şentepe-Ankara
Özcan, Pınar; Şengül, Hüseyin Tarık; Department of Urban Policy Planning and Local Governments (2005)
This thesis analyzes the validity of main assumptions of housing classes approach, which is a Weberian mode of analyses developed to explain the effects of spatial stratification on social structures of cities, in an empirical level through a case study. According to this approach, housing is a scarce resource which is subject to processes of competition between different social groups and struggles among these groups to get access to desirable housing types constitute the basis of urban social processes. I...
