Due to the complexity of occlusal contact, force and trajectory tracking is a crucial problem for the chewing robots. A position-based impedance control is proposed to realize hybrid control of chewing force and chewing trajectory in this paper. To ...

With the development of 5G, 6G, and beyond, wireless communications have taken a vital role in our daily life. The wide adoption of wireless devices and applications makes security of the wireless transmissions more critical. Many attacks aiming at ...

Multicarrier transmissions, such as orthogonal frequency/chirp division multiplexing (OF/CDM), offer high spectral efficiency and low complexity equalization in multipath fading channels at the cost of high peak-to-average power ratio (PAPR). High peak ...

With the rapid development of artificial intelligence technology, multitasking textual translation has attracted more and more attention. Especially after the application of deep learning technology, the performance of multitask translation text detection ...

Channel catfish (Ictalurus punctatus), tra catfish (Pangasianodon hypophthalmus) and walking catfish (Clarias macrocephalus) all belong to order Siluriformes, but I. punctatus does not possess an air breathing organ (ABO) and thus cannot breath in ...

In this paper, we show that, in vector-to-vector regression utilizing deep neural networks (DNNs), a generalized loss of mean absolute error (MAE) between the predicted and expected feature vectors is upper bounded by the sum of an approximation error, an ...

Orthogonal chirp division multiplexing (OCDM) is a fairly new multi-carrier scheme that employs the discrete Fresnel transform (DFnT) to digitally modulate data onto orthogonal chirps. Most work surrounding OCDM has been done in the context of optical ...

Applying Machine Learning (ML) techniques to design and optimize computer architectures is a promising research direction. Optimizing the runtime performance of a Network-on-Chip (NoC) necessitates a continuous learning framework. In this work, we ...

Chinese writing in primary and secondary schools occupies an extremely important position in Chinese education. With the advent of natural language processing, the automatic e ssay review system has gradually matured, which has greatly promoted the ...

In a TCP/IP network, a key to ensure efficient and fair sharing of network resources among its users is the TCP congestion control (CC) scheme. Previously, the design of TCP CC schemes is based on hard-wiring of predefined actions to specific feedback ...

Motivated by the connection with the genus of unoriented alternating links, Jin et al. (Acta Math Appl Sin Engl Ser, 2015) introduced the number of maximum state circles of a plane graph G, denoted by $$s_{\max }(G)$$smax(G), and proved that $$s_{\max }(...

Universal filtered multi-carrier (UFMC) has been widely researched for 5G communication systems. In this paper, we propose a new UFMC receiver model and signaling structure to support asynchronous transmissions. Since the UFMC transmitter contains sub-...

In MIMO wireless channels, channel estimation can provide a source of randomness common to sender and receiver that may be used to generate secret keys. These keys can provide information theoretically secure communication. Alternatively, a known MIMO ...
