This paper describes the submission from the National University of Singapore to the WMT 2011 Shared Evaluation Task and the Tunable Metric Task. Our entry is TESLA in three different configurations: TESLA-M, TESLA-F, and the new TESLA-B.

Abstract This paper analyzes candidate schemes for PPP/PPP-RTK (precise point positioning/real-time kinematic) data authentication. Asymmetric are proposed based on existing standards and compatible with GNSS messages. Post-quantum cryptographic signatures also reviewed discussed. Two selected analysis: digital signature (DS) ECDSA, delayed disclosure (DD) a hybrid scheme using the TES...

in this study, the effects of strength and direction of the magnetic field on lid-driven cavity flow in the whole range of magnetic field strength variations, which already used in practice up to present (0 to 10 tesla), are studied. the governing equations, including conservative equations of momentum, continuity and magnetic field equations were solved numerically. momentum and continuity equ...

PURPOSE To prospectively evaluate 7 Tesla time-of-flight (TOF) magnetic resonance angiography (MRA) in comparison to 1.5 Tesla TOF MRA and 7 Tesla non-contrast enhanced magnetization-prepared rapid acquisition gradient-echo (MPRAGE) for delineation of unruptured intracranial aneurysms (UIA). MATERIAL AND METHODS Sixteen neurosurgical patients (male n = 5, female n = 11) with single or multipl...

This paper documents a practical security evaluation of the Tesla Model X keyless entry system. In contrast to other works, system analysed in this employs secure symmetric-key and public-key cryptographic primitives implemented by Common Criteria certified Secure Element. We document internal workings system, covering key fob, body control module pairing protocol. Additionally, we detail our r...

BACKGROUND Using first-pass MRA (FP-MRA) spatial resolution is limited by breath-hold duration. In addition, image quality may be hampered by respiratory and cardiac motion artefacts. In order to overcome these limitations an ECG- and navigator-gated high-resolution-MRA sequence (HR-MRA) with slow infusion of extracellular contrast agent was implemented at 3 Tesla for the assessment of congenit...

PURPOSE The assessment of inducible wall motion abnormalities during high-dose dobutamine-stress cardiovascular magnetic resonance (DCMR) is well established for the identification of myocardial ischemia at 1.5 Tesla. Its feasibility at higher field strengths has not been reported. The present study was performed to prospectively determine the feasibility and diagnostic accuracy of DCMR at 3 Te...

This document introduces Timed Efficient Stream Loss-tolerant Authentication (TESLA). TESLA allows all receivers to check the integrity and authenticate the source of each packet in multicast or broadcast data streams. TESLA requires no trust between receivers, uses low-cost operations per packet at both sender and receiver, can tolerate any level of loss without retransmissions, and requires n...

BACKGROUND The purpose of this study was to define an optimal injection protocol for 5-10 min duration navigator-based coronary MR angiography using an intravascular gadolinium-based contrast agent (GBCA), which is better suited for steady-state coronary MR angiography than conventional GBCAs. METHODS Using projections from pharmacokinetic models of the intravascular concentration of gadofosv...
