Passive RFID systems used for list organization and benefit tracking normally use contention-based MAC protocols, such as the normal C1G2 protocol. Although the C1G2 protocol has the benefit that it is easy to apply, it suffers from wrongness and relatively low throughput when the number of tags in the network increases. It proposes a token-based MAC protocol called Token-MAC for passive RFID s...

Most state-of-the-art information extraction approaches rely on token-level labels to find the areas of interest in text. Unfortunately, these labels are time-consuming and costly to create, and consequently, not available for many real-life IE tasks. To make matters worse, token-level labels are usually not the desired output, but just an intermediary step. End-to-end (E2E) models, which take ...

The token ring FDDI and the slotted bus DQDB are the two currently most important standards for high speed networks. Each of these networks has its own specific advantages and disadvantages, and its own specific type of load for which it petforms best. We propose a new network design, called Universal Channel Network (UCN). UCN is adaptive and can be made to behave either like a token ring, a s...

Let G be a graph and Ds Dt two dominating sets of size k. Does there exist sequence 〈D0=Ds,D1,…,Dℓ−1,Dℓ=Dt〉 such that Di+1 can obtained from Di by replacing one vertex with its neighbors? In this paper, we investigate the complexity decision problem. We first prove problem is PSPACE-complete, even when restricted to split, bipartite or bounded treewidth graphs. On other hand, it solved in polyn...

In this paper, we propose a method to improve image classification performance using the fusion of CNN and transformer structure. case CNN, information about local area on an can be extracted well, but global extraction is limited. On other hand, has advantage in extraction, it requires much memory compared CNN. We apply consider feature vector each pixel resulting map by as token. At same time...

Pigeons made repeated choices between earning and exchanging reinforcer-specific tokens (green tokens exchangeable for food, red tokens exchangeable for water) and reinforcer-general tokens (white tokens exchangeable for food or water) in a closed token economy. Food and green food tokens could be earned on one panel; water and red water tokens could be earned on a second panel; white generaliz...

This paper investigated the problem of deriving token bucket parameters from the observed traffic patterns of computer network flows in two cases. In the basic case, we identified the set of token bucket parameters for any given flow so that all the packets in the flow will be delivered immediately without incurring any delay or loss. Then, we extended the basic case by adding a queue to the to...
