دانلود رایگان مجموعه مقالات علمی اشپرینگر در زمینه منطق فازی — بخش سی و یکم
منطق فازی (Fuzzy Logic) اولین بار در پی تنظیم نظریه مجموعه‌های فازی به وسیله پروفسور لطفی زاده (۱۹۶۵ میلادی) در صحنه محاسبات نو ظاهر شد. در واقع منطق فازی از منطق ارزش‌های «صفر و یک» نرم‌افزارهای کلاسیک فراتر رفته و درگاهی جدید برای دنیای علوم نرم‌افزاری و رایانه‌ها می‌گشاید، زیرا فضای شناور و نامحدود بین اعداد صفر و یک را نیز در منطق و استدلال‌های خود به کار می‌گیرد. در ادامه مقالات علمی انتشارات بین المللی اشپرینگر (Springer) در زمینه منطق فازی (Fuzzy Logic) برای دانلود آمده است. می توانید برای دانلود هر یک از مقالات از سرور دانلود متلب سایت، بر روی لینک دانلود هر یک از آن ها، کلیک کنید.

| عنوان اصلی مقاله | Evaluation of a fiberoptic-based system for measurement of optical properties in highly attenuating turbid media |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Divyesh Sharma, Anant Agrawal, L Stephanie Matchette, T Joshua Pfefer |
| چکیده / توضیح | Accurate measurements of the optical properties of biological tissue in the ultraviolet A and short visible wavelengths are needed to achieve a quantitative understanding of novel optical diagnostic devices. Currently, there is minimal information on optical property measurement approaches that are appropriate for in vivo measurements in highly absorbing and scattering tissues. We describe a novel fiberoptic-based reflectance system for measurement of optical properties in highly attenuating turbid media and provide an extensive in vitro evaluation of its accuracy. The influence of collecting reflectance at the illumination fiber on estimation accuracy is also investigated. |

| عنوان اصلی مقاله | Real-time intelligent pattern recognition algorithm for surface EMG signals |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Mahdi Khezri, Mehran Jahed |
| چکیده / توضیح | Electromyography (EMG) is the study of muscle function through the inquiry of electrical signals that the muscles emanate. EMG signals collected from the surface of the skin (Surface Electromyogram: sEMG) can be used in different applications such as recognizing musculoskeletal neural based patterns intercepted for hand prosthesis movements. Current systems designed for controlling the prosthetic hands either have limited functions or can only be used to perform simple movements or use excessive amount of electrodes in order to achieve acceptable results. In an attempt to overcome these problems we have proposed an intelligent system to recognize hand movements and have provided a user assessment routine to evaluate the correctness of executed movements. |

| عنوان اصلی مقاله | Assessing the effects of variables and background selection on the capture of the tick climate niche |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Agustín Estrada-Peña, Adrián Estrada-Sánchez, David Estrada-Sánchez, José de la Fuente |
| چکیده / توضیح | Modelling the environmental niche and spatial distribution of pathogen-transmitting arthropods involves various quality and methodological concerns related to using climate data to capture the environmental niche. This study tested the potential of MODIS remotely sensed and interpolated gridded covariates to estimate the climate niche of the medically important ticks Ixodes ricinus and Hyalomma marginatum. We also assessed model inflation resulting from spatial autocorrelation (SA) and collinearity (CO) of covariates used as time series of data (monthly values of variables), principal components analysis (PCA), and a discrete Fourier transformation. Performance of the models was measured using area under the curve (AUC), autocorrelation by Moran’s I, and collinearity by the variance inflation factor (VIF). |

| عنوان اصلی مقاله | Application of knowledge-driven spatial modelling approaches and uncertainty management to a study of Rift Valley fever in Africa |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Archie CA Clements, Dirk U Pfeiffer, Vincent Martin |
| چکیده / توضیح | There are few studies that have investigated uncertainties surrounding the scientific community's knowledge of the geographical distribution of major animal diseases. This is particularly relevant to Rift Valley fever (RVF), a zoonotic disease causing destructive outbreaks in livestock and man, as the geographical range of the disease is widening to involve previously unaffected regions. In the current study we investigate the application of methods developed in the decision sciences: multiple criteria decision making using weighted linear combination and ordered weighted averages, and Dempster-Shafer theory, implemented within the geographical information system IDRISI, to obtain a greater understanding of uncertainty related to the geographical distribution of RVF. The focus is on presenting alternate methods where extensive field data are not available and traditional, model-based approaches to disease mapping are impossible to conduct. |

| عنوان اصلی مقاله | Using GIS-based methods of multicriteria analysis to construct socio-economic deprivation indices |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Nathaniel Bell, Nadine Schuurman, Michael V Hayes |
| چکیده / توضیح | Over the past several decades researchers have produced substantial evidence of a social gradient in a variety of health outcomes, rising from systematic differences in income, education, employment conditions, and family dynamics within the population. Social gradients in health are measured using deprivation indices, which are typically constructed from aggregated socio-economic data taken from the national census – a technique which dates back at least until the early 1970's. The primary method of index construction over the last decade has been a Principal Component Analysis. Seldom are the indices constructed from survey-based data sources due to the inherent difficulty in validating the subjectivity of the response scores. We argue that this very subjectivity can uncover spatial distributions of local health outcomes. Moreover, indication of neighbourhood socio-economic status may go underrepresented when weighted without expert opinion. In this paper we propose the use of geographic information science (GIS) for constructing the index. We employ a GIS-based Order Weighted Average (OWA) Multicriteria Analysis (MCA) as a technique to validate deprivation indices that are constructed using more qualitative data sources. Both OWA and traditional MCA are well known and used methodologies in spatial analysis but have had little application in social epidemiology. |

| عنوان اصلی مقاله | Malignancy-associated metabolic profiling of human glioma cell lines using 1H NMR spectroscopy |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Wei Shao, Jinping Gu, Caihua Huang, Dan Liu, Huiying Huang, Zicheng Huang, Zhen Lin, Wensheng Yang, Kun Liu, Donghai Lin, Tianhai Ji |
| چکیده / توضیح | Ambiguity in malignant transformation of glioma has made prognostic diagnosis very challenging. Tumor malignant transformation is closely correlated with specific alterations of the metabolic profile. Exploration of the underlying metabolic alterations in glioma cells of different malignant degree is therefore vital to develop metabolic biomarkers for prognosis monitoring. |

| عنوان اصلی مقاله | Modeling approaches for qualitative and semi-quantitative analysis of cellular signaling networks |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Regina Samaga, Steffen Klamt |
| چکیده / توضیح | A central goal of systems biology is the construction of predictive models of bio-molecular networks. Cellular networks of moderate size have been modeled successfully in a quantitative way based on differential equations. However, in large-scale networks, knowledge of mechanistic details and kinetic parameters is often too limited to allow for the set-up of predictive quantitative models. |

| عنوان اصلی مقاله | Fuzzy obesity index (MAFOI) for obesity evaluation and bariatric surgery indication |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Susana Abe Miyahira, João Luiz Moreira Coutinho de Azevedo, Ernesto Araújo |
| چکیده / توضیح | The Miyahira-Araujo Fuzzy Obesity Index (MAFOI) for being used as an alternative in bariatric surgery indication (BSI) is validated in this paper. The search for a more accurate method to evaluate obesity and to indicate a better treatment is important in the world health context. Body mass index (BMI) is considered the main criteria for obesity treatment and BSI. Nevertheless, the fat excess related to the percentage of Body Fat (%BF) is actually the principal harmful factor in obesity disease that is usually neglected. The aim of this research is to validate a previous fuzzy mechanism by associating BMI with %BF that yields the Miyahira-Araujo Fuzzy Obesity Index (MAFOI) for obesity evaluation, classification, analysis, treatment, as well for better indication of surgical treatment. |

| عنوان اصلی مقاله | Fuzzy-logic, manual and semi-automated 2SD-based approaches for quantification of myocardial necrosis from late contrast enhancement magnetic resonance images: comparison with biochemical assessment of infarct size and left ventricular volumes and function early after myocardial infarction |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Nicolas Baron |
| چکیده / توضیح | Cardiac Magnetic Resonance Imaging (CMR) provides reliable estimation of the extent of necrosis after acute myocardial infarction (AMI). Nevertheless usual quantification methods are time consuming and subjective. We sought to assess necrosis extent with a new method (fuzzy c-means clustering), compared to usual methods, applied on Late Gadolinium Enhancement (LGE) sequences. Results were compared to biochemical markers of necrosis and LV functional parameters. |

| عنوان اصلی مقاله | Voice coil-based scanning probe microscopy |
| نوع مقاله | مقاله ژورنال |
| نویسندگان | Petr Klapetek, Miroslav Valtr, Václav Duchoň, Jaroslav Sobota |
| چکیده / توضیح | We present a novel system for large-area scanning probe microscopy (SPM) measurements based on minimum counter-force linear guidance mechanisms, voice coils, interferometers and fuzzy logic-based feedback loop electronics. It is shown that voice coil-based actuation combined with interferometry can be a good alternative to piezoceramic positioning systems, providing fast and still sufficient, precise displacements which range from nanometers to millimeters. Using fuzzy logic feedback control, it can be actuated even with only a few low-cost components, like a cheap single-chip microcontroller. As the final positioning resolution can be made independent on the electronics output resolution, the system can reach high positioning resolution even on very large scan sizes. This is a key prerequisite for developing novel generations of SPMs that would combine, in a very large range, with high-speed imaging. |
