An Application of Non-additive Measures and Corresponding Integrals in Tourism Management

القياسات الغير جمعية والتكاملات المقابلة لها قدمت في الاصل (أولا) من قبل شوكيت في عام 1953 وتم تعريفها بشكل مستقل من قبل سوجينو في عام 1974 من أجل تمديد القياس التقليدي عن طريق استبدال خاصية الإضافة إلى خاصية غير مضافة. ومن السمات(الميزات) الهامة للقياسات الغير جمعية والتكاملات الضبابية أنها يمكن أن تمثل أهمية مصادر المعلومات الفردية والتفاعلات فيما بينها. هناك العديد من التطبيقات حول القياسات الغير جمعية والتكاملات الضبابية مثل، معالجة الصور، صنع القرار متعدد المعايير(المقاييس)، اندماج المعلومات، التصنيف، والتعرف على الأنماط. في هذا البحث قدمنا نموذجًا رياضيًا لمناقشة تطبيق القياسات الغير جمعية والتكاملات المقابلة لها في ادارة السياحة. أولا وصفنا مسألة ادارة السياحة لآحدى شركات السياحة في العراق ثم طبقنا التكاملات الضبابية ( سوجينو, ﭽوكيت, شالكريت) المتعلقة بالقياسات الغير جمعية لتقييم درجة اشباع (رضا, قبول) السائح بالبقاء في مدينة معينة وبالتالي تحديد أفضل تقييم للمدن المقصودة.Non-additive measures and corresponding integrals originally have been introduced by Choquet in 1953 (1) and independently defined by Sugeno in 1974 (2) in order to extend the classical measure by replacing the additivity property to non-additive property. An important feature of non –additive measures and fuzzy integrals is that they can represent the importance of individual information sources and interactions among them. There are many applications of non-additive measures and fuzzy integrals such as image processing, multi-criteria decision making, information fusion, classification, and pattern recognition. This paper presents a mathematical model for discussing an application of non-additive measures and corresponding integrals in tourism management. First, the problem of tourism management is described for one of the tourism companies in Iraq. Then, fuzzy integrals (Sugeno integral, Choquet integral, and Shilkret integral) are applied with respect to non-additive measures to evaluate the grade of the gratification of the tourist of staying in a particular town for determining the best evaluation

Silicon as a ubiquitous contaminant in graphene derivatives with significant impact on device performance

Silicon-based impurities are ubiquitous in natural graphite. However, their role as a contaminant in exfoliated graphene and their influence on devices have been overlooked. Herein atomic resolution microscopy is used to highlight the existence of silicon-based contamination on various solution-processed graphene. We found these impurities are extremely persistent and thus utilising high purity graphite as a precursor is the only route to produce silicon-free graphene. These impurities are found to hamper the effective utilisation of graphene in whereby surface area is of paramount importance. When non-contaminated graphene is used to fabricate supercapacitor microelectrodes, a capacitance value closest to the predicted theoretical capacitance for graphene is obtained. We also demonstrate a versatile humidity sensor made from pure graphene oxide which achieves the highest sensitivity and the lowest limit of detection ever reported. Our findings constitute a vital milestone to achieve commercially viable and high performance graphene-based devices
