Complex Domain Approach for Reversible Data Hiding and Homomorphic Encryption: General Framework and Application to Dispersed Data
Ensuring the trustworthiness of data from distributed and resource-constrained environments, such as Wireless Sensor Networks or IoT devices, is critical. Existing Reversible Data Hiding (RDH) methods for scalar data suffer from low embedding capacity and poor intrinsic mixing between host data and watermark. This paper introduces Hiding in the Imaginary Domain with Data Encryption (H[i]dden), a novel framework based on complex number arithmetic for simultaneous information embedding and encryp…

Abnormal boundary decay for the fractional Laplacian
In this paper, we show that, for $α\in (0,2)$, the $C^{1, \rm Dini}$ regularity assumption on an open set $D\subset \mathbb R^d$ is optimal for the standard boundary decay property for nonnegative $α$-harmonic functions in $D$ and for the standard boundary decay property of the heat kernel $p^D(t,x,y)$ of the Dirichlet fractional Laplacian $Δ^{α/2}|_D$ by proving the following: (i) If $D$ is a $C^{1, \rm Dini}$ open set and $h$ is a non-negative function which is $α$-harmonic in $D$ a…

Geometry of Distance Protection
Distance relays detect faults on transmission lines. They face uncertainty from the fault's location and resistance, as well as the current from the line's remote terminal. In this paper, we aggregate this uncertainty with the Minkowski sum. This allows us to explicitly model the power grid surrounding the relay's line, and in turn accommodate any mix of synchronous machines and inverter-based resources. To make the relay's task easier, inverters can inject perturbations, or auxiliary signals, …

Observing Interaction Rather Than Interfaces
The science of Human-Computer Interaction (HCI) is populated by isolated empirical findings, often tied to specific technologies, designs, and tasks. This situation probably lies in observing the wrong object of study, that is to say, observing interfaces rather than interaction. This paper proposes an experimental methodology, powered by a research methodology, that enables tackling the ambition of observing interaction (rather than interfaces). These observations are done during the treatment…

A Diffusion-based Generative Machine Learning Paradigm for Contingency Screening
Contingency screening is a crucial part of electric power systems all the time. Power systems frequently encounter multiple challenging operational dilemmas that could lead to the instability of power systems. Contingency analysis is effort-consuming by utilizing traditional numerical analysis methods. It is commonly addressed by generating a whopping number of possible contingencies or manipulating network parameters to determine the worst scenarios. This paper proposes a novel approach that d…

A Dense and Efficient Instruction Set Architecture Encoding
Instruction density and encoding efficiency are some of the few things directly affected by an instruction set architecture's design. In contrast, a processor's implementation often significantly influences performance, power efficiency, and area usage. Therefore, a major goal of instruction set design should be maximizing instruction density and encoding efficiency. This paper introduces the design elements of the Scry instruction set architecture that most significantly affect instruction den…
