They Are All After You: Investigating the Viability of a Threat Model That Involves Multiple Shoulder Surfers [PDF]
, 2017 Many of the authentication schemes for mobile devices that were proposed lately complicate shoulder surfing by splitting the attacker's attention into two or more entities.

Space and Observers in Cosmology [PDF]
, 2001 I provide a prescription to define space, at a given moment, for an arbitrary observer in an arbitrary (sufficiently regular) curved space-time. This prescription, based on synchronicity (simultaneity) arguments, defines a foliation of space-time, which ...

Patterns of Eye Movements When Observers Judge Female Facial Attractiveness
Frontiers in Psychology, 2017 The purpose of the present study is to explore the fixed model for the explicit judgments of attractiveness and infer which features are important to judge the facial attractiveness.

Static Observers in Curved Spaces and Non-inertial Frames in Minkowski Spacetime [PDF]
, 2010 Static observers in curved spacetimes may interpret their proper acceleration as the opposite of a local gravitational field (in the Newtonian sense).

Moving Observers in an Isotropic Universe [PDF]
, 2006 We show how the anisotropy resulting from the motion of an observer in an isotropic universe may be determined by measurements. This provides a means to identify inertial frames, yielding a simple resolution to the twins paradox of relativity theory.

Polish Maritime Research, 2014 In cases when the navigational space of the manoeuvre performed by the ship is severely limited, the procedures making use of the rudder blade, propeller screw, and thrusters are very complicated.

Multi-score Learning for Affect Recognition: the Case of Body Postures [PDF]
, 2011 An important challenge in building automatic affective state recognition systems is establishing the ground truth. When the groundtruth is not available, observers are often used to label training and testing sets.

Applied Sciences, 2022 In this paper, an observer-based robust fault-tolerant predictive control (ORFTPC) strategy is proposed for Linear Parameter-Varying (LPV) systems subject to input constraints and sensor failures.

Contracting Nonlinear Observers: Convex Optimization and Learning from Data
, 2017 A new approach to design of nonlinear observers (state estimators) is proposed. The main idea is to (i) construct a convex set of dynamical systems which are contracting observers for a particular system, and (ii) optimize over this set for one which ...

SoC Estimation in Lithium-Ion Batteries with Noisy Measurements and Absence of Excitation
Batteries, 2023 Accurate State-of-Charge estimation is crucial for applications that utilise lithium-ion batteries. In real-time scenarios, battery models tend to present significant uncertainty, making it desirable to jointly estimate both the State of Charge and ...
