In a growing number of contexts, many situations require high-performance network virtualization. Paravirtualized network system adopts split driver model, and uses dynamic shared memory mechanism for communication between unprivileged guest domain and isolated driver domain. The dynamic shared memory mechanism introduces extra per-packet overheads, such as additional hypercalls and grant table operations. In this paper, we have implemented a new method called STAMP (static shared memory pipe), which uses static shared memory mechanism on Xen platform. STAMP comprises a two-way lockless producer-consumer circular buffer to carry network packets between split drivers. Once STAMP is established between guest domain and isolated driver domain, all packets are transferred through it to avoid extra overheads introduced by dynamic shared memory mechanism. In our evaluations, STAMP achieves availability and high efficiency, especially for scenarios of small messages. These results make the static shared memory mechanism an attractive solution for network paravirtualization.

It is used to judge the satisfiability of any logic formula. With the development of classical and non-classical logic, the resolution theory and method based on different logic system has been discussed widely and deeply. In the present paper, a new resolution principle by using ultrafilter in LP6(X) is put forward. Different from existed method of resolution, this resolution in this paper is based on ultrafilter of lattice implication algebra. In this paper, resolution principle based on any formula is discussed and soundness theorem is proved. Subsequently, algorithm of this resolution based on ultrafilter is given. Because of LP6(X) is a non-chain, non-boolean and non-well-ordered algebra structure, resolution based on LP6(X) will be the theoretical foundation of resolution on lattice-valued truth-field. Accordingly, the research in this paper will be helpful support for the application of intelligent reasoning system based on lattice-valued logic.

The goal of the method is to obtain a subset of correct assignments from a parsimonious set of 3D NMR experiments of (15)N, (13)C labeled proteins. Chemical shifts of sequential residue pairs are predicted from static protein structures using PPM_One, which are then compared with the corresponding experimental shifts. Globally optimized weighted matching identifies the assignments that are robust with respect to small changes in NMR cross-peak positions. The method, termed PASSPORT, is demonstrated for 4 proteins with 100-250 amino acids using 3D NHCA and a 3D CBCA(CO)NH experiments as input producing correct assignments with high reliability for 22% of the residues. The method, which works best for Gly, Ala, Ser, and Thr residues, provides assignments that serve as anchor points for additional assignments by both manual and semi-automated m...

The crystal structure and morphology of WO3 nanowires were investigated by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The obtained nanowires were hexagonal WO3. The major factors that influenced the morphology were the furnace temperature and the substrate position. The diameter of the nanowires decreased as the distance of the substrate from the raw material increased. Sensors were fabricated by pouring a few drops of nanowire-suspended ethanol onto oxidized Silicon substrates equipped with a pair of interdigitated Pt electrodes. The sensor made of the nanowires as thin as 50 nm showed the highest response to NO2 at a low operating temperature of 100 °C. The temperature dependence of the response was discussed in relation to the formation of NO2− and NO3− ions on the surface of WO3. The response slightly increased with decreasing diameter if the nanowires are regional depleted in NO2, while it largely increased if the nanowires are in volume depletion. A theoretical calculations based on assumptions were proposed in order to clarify the correlation between the nanowire response and their diameter.

First, valuation sets in LP(X) are defined and their properties are discussed. Based on these, a graded semantic consequence relation between an L-fuzzy set of formulae and a formula is specified. Accordingly, graded syntactic consequence relation is also given. It is demonstrated that these two classes of graded consequence relations are generalizations of counterparts in classical logic and even in LP(X). Furthermore, graded soundness problem, graded completeness theorem and graded deduction theorem for them are given and proven.

However, very limited literatures pay attentions to the reliability of dynamically provided resources. In this paper, we propose a failure rules aware node resource provision policy for heterogeneous services consolidated in cloud computing infrastructure. We evaluate our proposed policy with simulation approach, i.e., implement a simulator of heterogeneous service consolidation platform, which take characteristics of heterogeneous services (both characteristics of resource utility and failure rules), into consideration, and use two production traces to synthesize inputs. The results of evaluation indicate that our proposed resource provision policy is effective for providing robust nodes for heterogeneous services, i.e., our policy can mask more potential node reboot failures from services and leave less chances of unplanned failures, e.g., service failure or node reboot, compared with baseline fault re-provided policy. Meanwhile, our policy involves no negative impact on service performance and no negative impact on node's resource utility, compared with baseline policy.

Distributed systems are increasingly complex, full of various correlation and dependency, and exhibit dramatic dynamics. All these made traditional approaches prone to high false alarms. In this paper, we propose a novel system modeling technique, which encodes component's dynamic dependencies and behavior characteristics into system's meta-model and takes it as a unifying framework to deploy component's sub-models. We propose an automatic analyze approach to distill, from request travel paths, request path signatures, the essential information of component's dynamic behaviors, and use it to induce metamodel with Bayesian network, and then use the model to make fault location and diagnoses. We take up fault-injection experiments with RUBiS, a TPCW alike benchmark, simulating eBay.com. The results indicate that our model approach provides effective problem diagnosis, i.e., Bayesian network technique is effective for fault detecting and pinpointing, in terms of request tracing context. Moreover, meta-model induced with request paths, provides an effective guidance for learning statistical correlations among metrics across the system, which effectively avoid 'false alarms' in fault pinpointing. As a case study, we construct a proactive recovery framework, which integrate our system modeling technique with software rejuvenation technique to guarantee system's quality of services.
