| نوع مقاله | مقاله ژورنال |
| نویسندگان | M. A. Hasan, M. B. I. Reaz, M. I. Ibrahimy, M. S. Hussain, J. Uddin |
| چکیده / توضیح | Fetal electrocardiogram (FECG) signal contains potentially precise information that could assist clinicians in making more appropriate and timely decisions during labor. The ultimate reason for the interest in FECG signal analysis is in clinical diagnosis and biomedical applications. The extraction and detection of the FECG signal from composite abdominal signals with powerful and advance methodologies are becoming very important requirements in fetal monitoring. The purpose of this review paper is to illustrate the various methodologies and developed algorithms on FECG signal detection and analysis to provide efficient and effective ways of understanding the FECG signal and its nature for fetal monitoring. A comparative study has been carried out to show the performance and accuracy of various methods of FECG signal analysis for fetal monitoring. Finally, this paper further focused some of the hardware implementations using electrical signals for monitoring the fetal heart rate. This paper opens up a passage for researchers, physicians, and end users to advocate an excellent understanding of FECG signal and its analysis procedures for fetal heart rate monitoring system. |

| عنوان اصلی مقاله | Cost-Benefit Analysis for the Selection, Migration, and Operation of a Campus Management System |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Dipl.-Ök. Jon Sprenger, Dipl.-Ök. Marc Klages, Prof. Dr. Michael H. Breitner |
| چکیده / توضیح | An increasing number of students, together with organizational and technological requirements, pose new challenges for universities. For these reasons, Campus Management Systems provide a solution for the necessary IS-support in student administration. In order to ensure cost-effectiveness, an extensive cost-utility analysis of the campus management systems under consideration is required. The process model illustrated here facilitates a ten-step cost-utility analysis for the selection, migration and operation of a campus management System. The process-oriented approach addresses the challenges posed by cost and benefit allocation. The subsequent ten steps, using the case analysis of two large German universities, show that the implementation of an integrated campus management system can lead to significant cost saving effects. The presented process model enables comparative calculations of differences with regard to the alternatives. The approach enables a comprehensive decision-support system for the selection of a university-specific and individually applicable campus management system. |

| نوع مقاله | مقاله ژورنال |
| نویسندگان | Peter S. A. Glass MD |
| چکیده / توضیح | The specialty of anesthesia evolved following the discovery that drugs were able to create a reversible state of unconsciousness enabling surgical interventions to be performed. The need for human control over such powerful and potentially dangerous compounds was implicit in developing the specialty. The notion of anesthesia as an art practiced by professionals versed in human physiology and pharmacology has not been challenged until recently. |

| عنوان اصلی مقاله | Providing relevant information in an ambient services using service requester’s “logical area” |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Anahid Basiri, Mohammad Reza Malek |
| چکیده / توضیح | Ambient service is a kind of context-aware services which is related to the surrounding environment of the users. In other words, geographic area around the users is considered as contextual data to provide services. This geographical area around the user is called logical area which would be equivalent for “here” from an ordinary user’s point of view. Most of the time users are looking for resources around themselves or “here”. When “here” area of a user is overlapped or contained by a service area; which called “service domain” in ambient services; then user can get the service. So it is very important to know where is “here”. “Here” is a fuzzy spatial concept which is being frequently used in daily speaking. So it may be stated in requests of users e.g., finding cheapest restaurant “here” or around of somebody. The main step in a spatial context-aware application is determination of relevant information. Hence “here” concept, as a fundamental spatial concept, helps to provide relevant information to users so features located “here” or around of users, in which the best answer is located, should be found. As result, the area of “here” is very important to provide service in such cases. This issue becomes more complicated and important if the service requester is a mobile user, because the area of “here” changes over the time. In that case additional concepts and computations are needed to find “here” of that user. This paper is focused on modeling of “here” in an ambient service framework based on fuzzy set theory. |

| عنوان اصلی مقاله | Percolation-theory and fuzzy rule-based probability estimation of fault leakage at geologic carbon sequestration sites |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Yingqi Zhang, Curtis M. Oldenburg, Stefan Finsterle |
| چکیده / توضیح | Leakage of CO2 and displaced brine from geologic carbon sequestration (GCS) sites into potable groundwater or to the near-surface environment is a primary concern for safety and effectiveness of GCS. The focus of this study is on the estimation of the probability of CO2 leakage along conduits such as faults and fractures. This probability is controlled by (1) the probability that the CO2 plume encounters a conductive fault that could serve as a conduit for CO2 to leak through the sealing formation, and (2) the probability that the conductive fault(s) intersected by the CO2 plume are connected to other conductive faults in such a way that a connected flow path is formed to allow CO2 to leak to environmental resources that may be impacted by leakage. This work is designed to fit into the certification framework for geological CO2 storage, which represents vulnerable resources such as potable groundwater, health and safety, and the near-surface environment as discrete “compartments.” The method we propose for calculating the probability of the network of conduits intersecting the CO2 plume and one or more compartments includes four steps: (1) assuming that a random network of conduits follows a power-law distribution, a critical conduit density is calculated based on percolation theory; for densities sufficiently smaller than this critical density, the leakage probability is zero; (2) for systems with a conduit density around or above the critical density, we perform a Monte Carlo simulation, generating realizations of conduit networks to determine the leakage probability of the CO2 plume (P leak) for different conduit length distributions, densities and CO2 plume sizes; (3) from the results of Step 2, we construct fuzzy rules to relate P leak to system characteristics such as system size, CO2 plume size, and parameters describing conduit length distribution and uncertainty; (4) finally, we determine the CO2 leakage probability for a given system using fuzzy rules. The method can be extended to apply to brine leakage risk by using the size of the pressure perturbation above some cut-off value as the effective plume size. The proposed method provides a quick way of estimating the probability of CO2 or brine leaking into a compartment for evaluation of GCS leakage risk. In addition, the proposed method incorporates the uncertainty in the system parameters and provides the uncertainty range of the estimated probability. |

| عنوان اصلی مقاله | Spatial analysis of the mining and transport of rock minerals (aggregates) in the context of regional development |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Jan Blachowski |
| چکیده / توضیح | Rock minerals such as dimension and crushed stones and sands and gravels (aggregates) are indispensable materials for the building and construction industries. The growth in demand for these resources causes intensification of mining operations (and their consequent environmental impacts) and transport problems in regions abundant in rock minerals. The balanced management of these resources by regional policy-makers is difficult as it requires, among other things, comprehensive and up-to-date information on the spatial distribution and temporal changes of available reserves, demand, production, and transport. This information can be provided by means of spatial and temporal analyses through geographic information systems (GIS). In this research, the focus is on the following aspects of rock mineral (aggregates) resources and mining management in the context of regional spatial planning in the example region of Lower Silesia in Poland: the spatial and temporal changes in distribution and intensity of mining, the availability of economic reserves in active mines, the magnitude and distribution of road transport flows of aggregates, the potential of railways as an alternative means of transport, and the valorisation of undeveloped aggregates deposits to assess their suitability for future use. For the purposes of this study, cartographic models have been developed using GIS to facilitate analyses of these mineral resources, mining, and transport. The results of these analyses provide current and comprehensive information on the state of aggregates mineral resources, production and transport in the Lower Silesia region. They also give an insight into availability of rock mineral resources for the future. Knowledge of these processes is important for spatial development planning, especially physical infrastructure, conducted by national, regional, and local governments. |

| عنوان اصلی مقاله | Hydrogeochemistry and groundwater quality appraisal of part of south Chennai coastal aquifers, Tamil Nadu, India using WQI and fuzzy logic method |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | S. Krishna Kumar, R. Bharani, N. S. Magesh, Prince S. Godson, N. Chandrasekar |
| چکیده / توضیح | The present study was carried out to evaluate the groundwater quality and its suitability for drinking purposes in the urban coastal aquifers of part of south Chennai, Tamil Nadu, India. Twenty-three groundwater samples were collected during March 2012. The minimum and maximum values of pH (6.3–8 on scale), electrical conductivity (620–12,150 μS/cm), total dissolved solids (399.28–7,824.6 mg/l), carbonate (0–30 mg/l), bicarbonate (0.9–58.9 mg/l), chloride (70.9–4,067.89 mg/l), sulphate (17.4–105 mg/l), nitrate (0.4–6.0 mg/l), calcium (30–200 mg/l), magnesium (1.2–164 mg/l), sodium (69–1,490 mg/l) and potassium (8–340 mg/l) were recorded in the coastal aquifers of Chennai city. The groundwater samples show that the majority of the sampling points clustered on the NaCl and mixed CaMgCl facies of the piper trilinear diagram. In the Gibbs diagram, the majority of the sampling points fall under rock water and evaporation dominance field. Fuzzy membership classification suggests that the majority of the samples fall under good water type followed by excellent water and poor water categories. Groundwater quality index showing the majority of the samples falls under excellent to poor category of water. A positive correlation was observed with Cl−, SO4 2−, Ca2+, Na+, K+, EC and TDS. The extracted results of the correlation matrix and geochemical analysis suggest that the dominant ions of groundwater (Na+, Ca2+, K+, Cl− and SO4 2−) were derived from seawater intrusion and gypsum dissolution process. Nitrate concentration is most significantly derived from anthropogenic sources. |

| عنوان اصلی مقاله | Water supply management using an extended group fuzzy decision-making method: a case study in north-eastern Iran |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Yasser Minatour, Hossein Bonakdari, Mahdi Zarghami, Maryam Ali Bakhshi |
| چکیده / توضیح | The purpose of this study was to develop a group fuzzy multi-criteria decision-making method to be applied in rating problems associated with water resources management. Thus, here Chen’s group fuzzy TOPSIS method extended by a difference technique to handle uncertainties of applying a group decision making. Then, the extended group fuzzy TOPSIS method combined with a consistency check. In the presented method, initially linguistic judgments are being surveyed via a consistency checking process, and afterward these judgments are being used in the extended Chen’s fuzzy TOPSIS method. Here, each expert’s opinion is turned to accurate mathematical numbers and, then, to apply uncertainties, the opinions of group are turned to fuzzy numbers using three mathematical operators. The proposed method is applied to select the optimal strategy for the rural water supply of Nohoor village in north-eastern Iran, as a case study and illustrated example. Sensitivity analyses test over results and comparing results with project reality showed that proposed method offered good results for water resources projects. |

| عنوان اصلی مقاله | Prediction of ground water quality index to assess suitability for drinking purposes using fuzzy rule-based approach |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | A. K. Gorai, S. A. Hasni, Jawed Iqbal |
| چکیده / توضیح | Groundwater is the most important natural resource for drinking water to many people around the world, especially in rural areas where the supply of treated water is not available. Drinking water resources cannot be optimally used and sustained unless the quality of water is properly assessed. To this end, an attempt has been made to develop a suitable methodology for the assessment of drinking water quality on the basis of 11 physico-chemical parameters. The present study aims to select the fuzzy aggregation approach for estimation of the water quality index of a sample to check the suitability for drinking purposes. Based on expert’s opinion and author’s judgement, 11 water quality (pollutant) variables (Alkalinity, Dissolved Solids (DS), Hardness, pH, Ca, Mg, Fe, Fluoride, As, Sulphate, Nitrates) are selected for the quality assessment. The output results of proposed methodology are compared with the output obtained from widely used deterministic method (weighted arithmetic mean aggregation) for the suitability of the developed methodology. |
