The Philosophy of Information and Ethics in the Internet of Things Technology
Published in Abhik Chaudhuri, Internet of Things, for Things, and by Things, 2018
Once the potential end user interprets the existence of IoT technology, the next step is to ask: ‘How do we experience it?’ Various IoT applications, like smart-room ambience devices that automatically gather contextual data and change the ambience in a room through pre-set algorithmic rules, smart monitoring devices that alert the nearest police station about security violation in a locality, and others build consciousness about IoT technology among users through context-based conditioned response and action mechanism. According to Professor T.D. Wilson, the aim of phenomenology is “to study how human phenomena are experienced in consciousness, in cognitive and perceptual acts, as well as how they may be valued or appreciated aesthetically. Phenomenology seeks to understand how persons construct meaning.”3
Chiral fermion asymmetry in high-energy plasma simulations

Numerical simulations are a key tool for studying the properties of high-energy plasmas, such as those of the early Universe or of proto-neutron stars. At energies , the number of degrees of freedom increases by the chiral chemical potential, which is non-zero in case of an asymmetry between the number of left- and right-handed fermions. Through the additional electric current in the presence of such an asymmetry, the phenomenology of chiral MHD is even richer than that of classical MHD and numerical simulations are needed to gain a deeper understanding of the plasma and magnetic field evolution. To our knowledge, one of the first high-order parallelised codes, which has been used for chiral MHD, is the Pencil Code. A central purpose of this paper was to describe the implementation of the chiral MHD module in the Pencil Code, to discuss the relevant parameters and initial conditions in a chiral plasma, and to point out crucial differences to classical MHD. We also have presented typical applications of the chiral MHD module and discussed the obtained numerical results.

Qiu et al. [9] proposed a phenomenology based on an 8th-order Landau–Ginzburg–Devonshire (LGD) potential model to explain the experimental data [14] for the T−x phase diagram where the only monoclinic phase MC exists. The refined T−x phase diagrams [3,4,10,17] including two monoclinic and one orthorhombic phases in the MPB region of PMN-PT single crystal cannot be explained by the phenomenology.
