On the temperature control in self-controlling hyperthermia therapy, Article Journal of Magnetism and Magnetic Materials ; Volume 416 , 2016 , Pages 134-140 ; 03048853 (ISSN) ; Sharif University of Technology
In self-controlling hyperthermia therapy, once the desired temperature is reached, the heat generation ceases and overheating is prevented. In order to design a system that generates sufficient heat without thermal ablation of surrounding healthy tissue, a good understanding of temperature distribution and its change with time is imperative. This study is conducted to extend our understanding about the heat generation and transfer, temperature distribution and temperature rise pattern in the tumor and surrounding tissue during self-controlling magnetic hyperthermia. A model consisting of two concentric spheres that represents the tumor and its surrounding tissue is considered and temperature...
A New Approach to Loss Aversion in Repeated Gambles, M.Sc. Thesis Sharif University of Technology ; Zamani, Shiva
After introducing “Prosopect Theory” by Kahneman and Tversky in 1979, it is mostly used as an alternative to expected utility theory in order to study human decision making under risky situatutions. Loss aversion has been considered as an important aspect of this theory. In this study, we review loss aversion and the effects of education and gender on it. Finally, we study the effect of repeating a gamble on its participants’ loss aversions. The results show that education and gender have direct effects on loss aversion and repeating a gamble can decrease loss aversion of participants.
Modeling of self-controlling hyperthermia based on nickel alloy ferrofluids: Proposition of new nanoparticles, Article Journal of Magnetism and Magnetic Materials ; Volume 335 , 2013 , Pages 59-63 ; 03048853 (ISSN) ; Madaah Hosseini, H. R ; Wolff, M ; Sharif University of Technology
In order to provide sufficient heat without overheating healthy tissue in magnetic fluid hyperthermia (MFH), a careful design of the magnetic properties of nanoparticles is essential. We perform a systematic calculation of magnetic properties of Ni-alloy nanoparticles. Stoner-Wohlfarth model based theories (SWMBTs) are considered and the linear response theory (LRT) is used to extract the hysteresis loop of nickel alloy nanoparticles in alternating magnetic fields. It is demonstrated that in the safe range of magnetic field intensity and frequency the LRT cannot be used for the calculation of the area in the hysteresis for magnetic fields relevant for hyperthermia. The best composition and...
Design for well-being: The fourth generation of technology development, Article Technology in Society ; Volume 67 , November , 2021 ; 0160791X (ISSN) ; Ansarian, Z ; Taqavi, M ; Heidari, S ; Sharif University of Technology

Despite the importance of well-being, few studies have been conducted on the relationship between well-being and technology. In this paper, the development of technology from the perspective of well-being studies are divided into three generations. In higher generations, the main criterion of technology development becomes more comprehensive, in order to decrease the side effects of technology. We introduce the fourth generation in which well-being is the main criterion of the design process. Although it may not seem necessary to say that the purpose of most technologies is implicitly well-being, we show that the domination of physical pleasure in terms of “use and convenience” in the modern...
