With the advance in automatic speech recognition, voice user interface has gained popularity recently. Since COVID-19 pandemic, VUI is increasingly preferred online communication due to its non-contact. Additionally, various ambient noise impedes public applications of interfaces requirement audio-only recognition methods for a high signal-to-noise ratio. In this paper, we present Wavoice, first noise-resistant multi-modal system that fuses two distinct sensing modalities, i.e.,...

Abstract For the four degrees of freedom (4‐DOF) trajectory tracking control problem underwater vehicles in presence parametric uncertainties and external disturbances, a novel multivariable output feedback adaptive nonsingular terminal sliding mode (ANTSMC) approach is proposed based on equivalent injection observer (ASMO) ANTSMC method. The ASMO applied to reconstruct full states finite time method designed stabilize error small field time. approach, using technology, does not require...

Compared to vertical wells, horizontal wells may exhibit identical logging curve characteristics corresponding different target formations, and the same formation can display varying features. To clarify these response character-istics, a numerical simulation was conducted using fast Hankel transform method simulate array induction responses for wells. The covers both constant-inclination well trajectories in simple formations waveform Oklahoma formations. Conduct detailed analysis of impact...

Internet of Things (IoT) devices are hindered from communicating with their neighbors by incompatible protocols or electromagnetic interference. Existing solutions adopting physical covert channels have limitations in receiver distinction, additional hardware, conditional placement, contact. Our system, Deaf-Aid, utilizes the stealthy speaker-to-gyroscope channel to build robust protocol-independent communication automatic identification. Deaf-Aid exploits ultrasonic signals at a frequency...

IMU-based eavesdropping has brought growing concerns over smartphone users' privacy. In such attacks, adversaries utilize IMUs that require zero permissions for access to acquire speeches. A common countermeasure is limit sampling rates (within 200 Hz) reduce overlap of vocal fundamental bands (85-255 and inertial measurements (0-100 Hz). Nevertheless, we experimentally observe below Hz still record adequate speech-related information because aliasing distortions. Accordingly, propose a...

Abstract Different wheat genotypes were treated with gamma‐rays, sodium azide (SA) and EMS before tissue culture immature embryos from M 1 plants or shortly after exposure to gamma‐rays used initiate callus culture. Thousands of regenerated investigate the effect mutagenic treatments on somaclonal variation in 3 R 2 generations. The results showed that mutagen‐induced damage terms reduction plant height, fertility spike length not outstanding as compared untreated control. In generation,...

This paper presents the test methods of studying insulation characteristics transformer oil at low temperatures. Karamay DB-45 oils were selected as initial specimens. Oil samples different quality indexes obtained after processing by vacuum purifier. Each kind sample was carried out experiments on insulating properties The temperature dependence dielectric strength temperatures (-20°C~10°C) is statistical analysis results. (1)The relation curves breakdown voltage vs. show "U"-type features...

Covert eavesdropping via microphones has always been a major threat to user privacy. Benefiting from the acoustic non-linearity property, ultrasonic microphone jammer (UMJ) is effective in resisting this long-standing attack. However, prior UMJ researches underestimate adversary's attacking capability reality and miss critical metrics for thorough evaluation. The strong assumptions of adversary unable retrieve information under low word recognition rate, weak denoising abilities model make...

In cyber-physical systems, inertial sensors are the basis for identifying motion states and making actuation decisions. However, extensive studies have proved vulnerability of those under acoustic transduction attacks, which leverage malicious acoustics to trigger sensor measurement errors. Unfortunately, threat from such attacks is not assessed properly because incomplete investigation on attack's potential, especially towards multiple-degree-of-freedom e.g., drones. To thoroughly explore...

Human-machine interactions (HMIs), e.g., touchscreens, are essential for users to interact with mobile devices. They also beneficial in resisting emerging active attacks, which aim at maliciously controlling devices, smartphones and tablets. With touchscreen-like HMIs, can notice interrupt malicious actions conducted by the attackers timely perform necessary countermeasures, tapping 'Quit' button on touchscreen. However, effect of HMI-oriented attacks has not been investigated yet. In this...
