This paper examines my personal process of materializing lived experiences into a material installation, and how this process affected how I perceive those lived experiences. The process is investigated through to the image schematic structure of experience, in relation to the metaphoric nature of material substances,…

In power transformers, liquid insulating materials are used as cooling agent and electrical insulator. Currently, mineral oil is the most commonly used liquid insulation material in power transformers. However, mineral oil has some drawbacks in its characteristics such as a deprived biodegradability and high flammabil…
We present an overview of Majorana qubits based on one-dimensional semiconducting nanowires partially covered with a conventional superconductor. Majorana zero modes emerge at the wire ends when this hybrid system transitions from a conventional superconducting phase to a topological phase, in general occurring on inc…

La soldadura constituye uno de los métodos de unión más utilizados para la fijación de elementos que posee, además, amplia variedad de aplicaciones en la industria y los servicios. Sin embargo, es habitual encontrar tensiones residuales que se generan en las uniones soldadas a causa de los gradientes térmicos. En el p…
Cu2ZnSnSe4(CZTSe) is one of the promising kesterite-type light absorbing materials to produce low cost third generation solar cells but suffers from poor efficiency. To investigate if modification in buffer layer can enhance efficiency, ZnxCd1-xS alloy is considered as buffer material in this work for a typical CZTSe…
PURPOSE: To investigate the effects of recasting on metallographic microstructure of cobalt-chromium(Co-Cr), commercially pure titanium(cpTi), palladium-copper-gallium(Pd-Cu-Ga), aurum-platinum(Au-Pt) ceramic alloys. METHODS: Without adding new alloys, Co-Cr, cpTi, Pd-Cu-Ga and Au-Pt ceramic alloys were recasted for 1…
Insulating oil is used as insulant and coolant in transformers and other such electrical equipments. Presently, mineral oils are widely used in transformers and electrical equipments as insulating oils. These mineral oils are less biodegradable. Hence, from the environment point of view, vegetable oils are used as alt…
In the community of computational materials science, one of the challenges in hierarchical multiscale modeling is information-passing from one scale to another, especially from the molecular model to the continuum model. A machine-learning-enhanced approach, proposed in this paper, provides an alternative solution. In…
Graphene has shown a great scope beyond the bulk silicon devices for future transistor applications. Even though it has undergone intensive investigations through experimental approach, there are no easy and time efficient computational approaches for analysing the graphene transistors. In this paper we provide method…
Surfactant flooding for the mobilization of residual oil is a promising technology for enhanced oil recovery (EOR) and surfactant enhanced aquifer remediation (SEAR). A significant economic barrier to the widespread use of the technology is the loss of surfactant through adsorption on aquifer and reservoir minerals. E…
In this paper the microwave absorbing properties of multiband Salisbury screen absorber design which is constructed using multi-layer FSS is investigated. The multiband properties are obtained by exploiting the phase change offered by the cross dipole FSS. Hence, the details phase characteristic are important to achie…
Return Oriented Programming is one of the most important software security challenges nowadays. It exploits memory vulnerabilities to control the state of the program and hijacks its control flow. Existing defenses usually focus on how to protect the control flow or face the challenge of how to maintain the taint mark…
In this paper, we present a novel and a practical method to generate multi-mode orbital angular momentum (OAM). The OAM modes of l=1, 2, 3, 4 can be generated at 2.5GHz by using four helical antennas arranged like concentric circles which is called the helical antenna array (HAA). To prove the generation of the OAM wa…
UHV direct current mixed-voltage transmission lines on the same tower can effectively solve the contradiction between growing power demand and resource shortage of power transmission corridors, thus doing research on the lightning protection performance of the transmission lines is of great significance. Based on EMTP…
The degradation mechanism and physical properties of an FKM O-ring were observed with thermal aging in this experiment. From X-ray photoelectron spectroscopy (XPS) analysis, we could observe carbon (285 eV), fluoro (688 eV), and oxygen (531 eV) peaks. Before thermal aging, the concentration of fluoro atoms was 51.23%,…
Gas insulated metal enclosed transmission line (GIL) is gradually replacing traditional overhead lines and high voltage cables due to its large transmission capacity and low loss. As the basis of studying optical detection of partial discharge (PD), it is necessary to pay attention to the propagation characteristics o…

Accumulation of interfacial charge creates local field distortion during insulation response measurement. Furthermore, such localized field enhancement affects the interaction between polar compounds present within oil-paper insulation and in turn affects its aging process. By getting sufficient trap energy (normally…
