This paper investigates a consensus problem of the fractional version of second-order system with communication delay under both directed and undirected topologies. By applying the frequency domain method, a sufficient condition is given to ensure the fractional version of second-order consensus facing communication delays. It is proof that fractional version of second-order consensus can be reached...
This paper presents an optimistic protocol based on the scheme of public verifiable secret share for distributed fair exchange. A distributed third party is designed to guarantee the fairness of exchange. Comparing to traditional trusted third party, this distributed third party is not fixed but dynamically selected by the players of exchange. This solution can effectively remove the risk of single...
This paper presents an optimistic fair exchange protocol based on public verifiable secret sharing for e-procurement applications in Peer-2-Peer networks. According to the decentralized feature of such a network, a distributed third party is designed to guarantee the fairness of exchange. Comparing to traditional trusted third party, this distributed third party is not fixed but dynamically selected...
On-line testing offers a promising method for detecting defects, fluidic abnormalities, and bioassay malfunctions in microfluidic biochips. To reduce product cost for disposable biochips, testing steps and functional fluidic operations must be implemented on pin-constrained designs. However, previous testing methods for pin-constrained designs do not optimize test schedules to reduce the number of...
Tiered wireless sensor networks (WSNs) have many advantages over traditional WSNs. However they are vulnerable to security attacks, especially those targeting at the storage nodes that bu er and process the data readings from sensors. In this paper, we propose a Secure Data Collection protocol - SDC to support time-based queries in tiered WSNs. With small overhead introduced to data communication,...
Reentry is the main form of arrhythmia. To know when and where the reentry starts in Long QT Syndromes (LQTS) and its relation with M cells distribution, the Luo-Rudy dynamic ionic model (LRdOO) of the mammalian ventricular action potential (AP) was used in a two dimensional transmural tissue sheets simulation. LQTS was simulated by reducing the membrane conductance of IKs for LQT1 and IKr for LQT2,...
As an emerging model for new enterprise data centers, the cloud paradigm provides a disruptive market opportunity to better utilize computing resources and reduce IT complexity. To provide the cloud computing service, the provisioning of the cloud infrastructure in data centers is a pre-request. However, the provisioning for systems and applications on large number of physical machines is traditionally...
A multi-party fair exchange protocol is a cryptographic protocol allowing several parties to exchange electronic items in such a way that everyone gives an item away if and only if it receives an item in return. In this paper, we present a new multi-party fair exchange protocol with an Off-line Semi-Trust Third Party (OSTTP). The new protocol can ensure strong fairness and the OSTTP can't get the...
For electronic items without generability or revocability, previous optimistic exchange protocols can't guarantee strong fairness. Gradual protocols assume equal computing power. And online-TTP (Third Trusted Party) protocols often suffer from communication bottle-neck. A gradual and optimistic fair exchange protocol is presented in this paper to solve the problem. Secrets are gradually exchanged...
