The saturated prefilter monad [article]

Hongliang Lai, Dexue Zhang, Gao Zhang
2020 arXiv   pre-print
This paper considers some extensions of the notion of filter to the quantale-valued context, including saturated prefilter, ⊤-filter and bounded saturated prefilter. The question is whether these constructions give rise to monads on the category of sets. It is shown that the answer depends on the structure of the quantale. Specifically, if the quantale is the unit interval equipped with a continuous t-norm, then these constructions give rise to monads if and only if the implication operator

MetaRadar: Indoor Localization by Reconfigurable Metamaterials [article]

Haobo Zhang, Jingzhi Hu, Hongliang Zhang, Boya Di, Kaigui Bian, Zhu Han, Lingyang Song
2020 arXiv   pre-print
Indoor localization has drawn much attention owing to its potential for supporting location based services. Among various indoor localization techniques, the received signal strength (RSS) based technique is widely researched. However, in conventional RSS based systems where the radio environment is unconfigurable, adjacent locations may have similar RSS values, which limits the localization precision. In this paper, we present MetaRadar, which explores reconfigurable radio reflection with a

By changing the reflectivity of metamaterial, MetaRadar modifies the radio channels at different locations, and improves localization accuracy by making RSS values at adjacent locations have significant differences. However, in MetaRadar, it is challenging to build radio maps for all the radio environments generated by metamaterial units and select suitable maps from all the possible maps to realize a high accuracy localization. To tackle this challenge, we propose a compressive construction technique which can predict all the possible radio maps, and propose a configuration optimization algorithm to select favorable metamaterial reflectivities and the corresponding radio maps. The experimental results show a significant improvement from a decimeter-level localization error in the traditional RSS-based systems to a centimeter-level one in MetaRadar.

Many-valued complete distributivity [article]

Hongliang Lai, Dexue Zhang
2006 arXiv   pre-print
Categories enriched over a commutative unital quantale can be studied as generalized, or many-valued, ordered structures. Because many concepts, such as complete distributivity, in lattice theory can be characterized by existence of certain adjunctions, they can be reformulated in the many-valued setting in terms of categorical postulations. So, it is possible, by aid of categorical machineries, to establish theories of many-valued complete lattices, many-valued completely distributive

This paper presents a systematical investigation of many-valued complete distributivity, including the topics: (1) subalgebras and quotient algebras of many-valued completely distributive lattices; (2) categories of (left adjoint) functors; and (3) the relationship between many-valued complete distributivity and properties of the quantale of truth values. The results show that enriched category theory is a very useful tool in the study of many-valued versions of order-related mathematical entities.

Quantale-valued dissimilarity [article]

Hongliang Lai, Lili Shen, Yuanye Tao, Dexue Zhang
2019 arXiv   pre-print
In the same spirit of the theory of apartness relations of Scott, a positive theory of dissimilarity valued in an involutive quantale Q is established without the aid of negation, which dualizes the theory of Q-valued sets in the sense of Höhle--Kubiak that can be understood as sets equipped with a similarity valued in Q. It is demonstrated that sets equipped with a Q-valued dissimilarity are precisely symmetric categories enriched in a quantaloid constructed out of Q, whose morphisms are

A characterization of flat ideals in the unit interval with the canonical fuzzy order is obtained with the help of the ordinal sum decomposition of continuous t-norms. This characterization will be useful in the study of topological and domain theoretic properties of fuzzy orders.

A generalization on derivations of Lie algebras [article]

Hongliang Chang, Yin Chen, Runxuan Zhang
2020 arXiv   pre-print
We initiate a study on a range of new generalized derivations of finite-dimensional Lie algebras over an algebraically closed field of characteristic zero. This new generalization of derivations has an analogue in the theory of associative prime rings and unites many well-known generalized derivations that have already appeared extensively in the study of Lie algebras and other nonassociative algebras. After exploiting fundamental properties, we introduce and analyze their interiors, especially

A characterization for graphs having strong parity factors [article]

Hongliang Lu, Zixuan Yang, Xuechun Zhang
2020 arXiv   pre-print
A graph G has the strong parity property if for every subset X⊆ V with |X| even, G has a spanning subgraph F with minimum degree at least one such that d_F(v)≡ 1 2 for all v∈ X, d_F(y)≡ 0 2 for all y∈ V(G)-X. Bujtás, Jendrol and Tuza (On specific factors in graphs, Graphs and Combin., 36 (2020), 1391-1399.) introduced the concept and conjectured that every 2-edge-connected graph with minimum degree at least three has the strong parity property.

Wireless Indoor Simultaneous Localization and Mapping Using Reconfigurable Intelligent Surface [article]

Ziang Yang, Haobo Zhang, Boya Di, Hongliang Zhang, Kaigui Bian, Lingyang Song
2021 arXiv   pre-print
Indoor wireless simultaneous localization and mapping (SLAM) is considered as a promising technique to provide positioning services in future 6G systems. However, the accuracy of traditional wireless SLAM system heavily relies on the quality of propagation paths, which is limited by the uncontrollable wireless environment. In this paper, we propose a novel SLAM system assisted by a reconfigurable intelligent surface (RIS) to address this issue. By configuring the phase shifts of the RIS, the

However, the selection of phase shifts heavily influences the localization and mapping phase, which makes the design very challenging. To tackle this challenge, we formulate the RIS-assisted indoor SLAM optimization problem and design an error minimization algorithm for it. Simulations show that the RIS assisted SLAM system can decrease the positioning error by at least 31% compared with benchmark schemes.

Cellular Controlled Cooperative Unmanned Aerial Vehicle Networks with Sense-and-Send Protocol [article]

Shuhang Zhang, Hongliang Zhang, Boya Di, Lingyang Song
2018 arXiv   pre-print
In this paper, we consider a cellular controlled unmanned aerial vehicle (UAV) sensing network in which multiple UAVs cooperatively complete each sensing task. We first propose a sense-and-send protocol where the UAVs collect sensory data of the tasks and transmit the collected data to the base station. We then formulate a joint trajectory, sensing location, and UAV scheduling optimization problem that minimizes the completion time for all the sensing tasks in the network. To solve this NP-hard

An iterative trajectory, sensing, and scheduling optimization (ITSSO) algorithm is proposed to solve these sub-problems jointly. The convergence and complexity of the ITSSO algorithm, together with the system performance are analysed. Simulation results show that the proposed ITSSO algorithm saves the task completion time by 15% compared to the non-cooperative scheme.
