Photonic approach for Doppler-frequency-shift and angle-of-arrival measurement with direction unambiguity and high precision.

Applied Optics, 2023
A novel, to the best of our knowledge, scheme based on a dual-drive Mach-Zehnder modulator (DDMZM) is proposed for Doppler-frequency-shift (DFS) and angle-of-arrival (AOA) measurement without direction ambiguity.

Unambiguity and Fewness for Nonuniform Families of Polynomial-Size Nondeterministic Finite Automata

Reachability Problems, 2023
Nonuniform families of polynomial-size finite automata, which are series of indexed finite automata having polynomially many inner states, are used in the past literature to solve nonuniform families of promise decision problems.

Unambiguity of Polysemy: On the Definition of the Qur’anic Discipline al-wujūh wa-n-naẓā’ir

Vostok. Afro-aziatskie obshchestva: istoriia i sovremennost, 2023
Since the earliest period of the development of Muslim exegetics, theologians have paid considerable attention to the problems of the Qur’anic lexicology, a special place among which is occupied by the topic of al-wujūh wa-n-naza’ir.

An Unambiguity Method for PD Radar using Orthogonal Binary Phase Coded Signal

2022 2nd Asia Conference on Information Engineering (ACIE), 2022
In order to decrease the blind area of pulse Doppler radar, narrow transmitting pulse is used in this paper, and high pulse repetition frequency working mode is adopted to avoid velocity ambiguity. In this paper, orthogonal binary phase coded signals are

Unambiguity of Python Language Elements for Static Analysis

IEEE Working Conference on Source Code Analysis and Manipulation, 2021
Static analysis is a technique for gathering some meaningful information during compilation-time and using it for further processing. This technique is applied in bug finding, code comprehension and in many other areas.

Compensation of Motion-Induced Phase Errors and Enhancement of Doppler Unambiguity in TDM–MIMO Systems by Model-Based Estimation

IEEE Sensors Letters, 2020
Utilization of multiple input multiple output (MIMO) systems in radar and channel sounding has gained increased attention in recent years. Quite often, time-division multiplexing (TDM) is employed to realize orthogonal waveforms at the transmitter. Apart

An unambiguity Method for PD Radar using OFDM- LFM Signal

2021 International Conference on Information Technology and Biomedical Engineering (ICITBE), 2021
In order to avoid velocity ambiguity of linear frequency modulation (LFM) pulse Doppler (PD) radar, this paper adopts the high pulse repetition frequency (HPRF) working mode.

Hierarchical Unambiguity

open access: yesLecture Notes in Computer Science, 2006
We develop techniques to investigate relativized hierarchical unambiguous computation. We apply our techniques to generalize known constructs involving relativized unambiguity based complexity classes (UP and \mathcal{UP}) to new constructs involving arbitrary higher levels of the relativized unambiguous polynomial hierarchy (UPH).

Making nondeterminism unambiguous

Proceedings 38th Annual Symposium on Foundations of Computer Science, 2000
Summary: We show that in the context of nonuniform complexity, nondeterministic logarithmic space bounded computation can be made unambiguous. An analogous result holds for the class of problems reducible to context-free languages. In terms of complexity classes, this can be stated as \[ \begin{aligned} \text{NL/poly} &= \text{UL/poly},\\ \text{LogCFL ...
