This article discusses the control design and experiment validation of a flexible two-link manipulator (FTLM) system represented by ordinary differential equations (ODEs). A reinforcement learning (RL) strategy is developed that based on actor–critic structure to enable vibration suppression while retaining trajectory tracking. Subsequently, closed-loop with proposed RL algorithm proved be semi-global uniform ultimate bounded (SGUUB) Lyapunov's direct method. In simulations, approach...

As more and Web services are deployed, service's discovery mechanisms become essential. Similar can have quite different QoS levels. For service selection management purpose, it is necessary to explicitly, precisely, unambiguously specify various constraints metrics for descriptions. This paper provides a novel DAML-QoS ontology as complement DAML-S provide better model. Three layers defined together with clear role descriptions developments. Cardinality utilized describe the property...

Abstract To achieve high selectivity in the transformation from peroxymonosulfate to singlet oxygen, adaptive tuning of atomic spin state as structure varied is crucial. The angstrom confinement can effectively tune state, but developing an angstrom‐confined system challenging. Angstrom‐confined cobalt (Co) manganese (Mn) dual single atoms within flexible 2D carbon nitride interlayer are constructed drive by changing coordination under confinement. situ characterizations and density...

For the vision of ubiquitous, easily invokable Web services to become a reality, it will be necessary for service requesters compare quality-of-service (QoS) aspects various services. So standardized QoS information must part discovery process. This article surveys current research on and discovery, including ontologies such as OWL-S DAML-S. The authors then propose their own ontology, DAML-QoS, which provides detailed in DAML format.

As more and Web services are deployed, service’s discovery mechanisms become essential. Similar from different sources often exhibit quite Quality of Service (QoS) levels. For service selection management purpose, it is necessary to explicitly, precisely, flexibly specify various constraints QoS metrics for descriptions. This paper provides a novel ontology as complement DARPA Agent Markup Language—Service (DAML-S) Ontology provide better model. Three layers defined, together with clear role...

The value of customer loyalty has been well documented by academicians and practitioners. Nevertheless, prior literature paid little attention to the negative consequences loyalty, for example, entitlement behaviors (e.g. requests deeper discounts) complaint (voicing dissatisfaction company). This research empirically examines effects on voiced in context Frequent Flyer programs airline industry. Base partial least squares-structural equation modeling, results show that (1) a positive effect...

This paper is concerned with the estimation of performance measures two priority disciplines in a d-station re-entrant queueing network. Such networks arise from complex manufacturing systems such as wafer fabrication facilities. The considered are First-Buffer-First-Served (FBFS) and Last-Buffer-First-Served (LBFS). An analytical method developed to estimate long-run average workload at each station mean sojourn time When first-buffer-first-served discipline used, refined also developed....

Many goods manufacturers and service providers jointly deliver partnered hybrid offerings to achieve competitive advantage superior performance. In such cases, may emphasize different aspects of in their offerings. Do benefit equally from emphasizing satisfaction? the performance effects emphases on satisfaction vary across goods? The authors examine two satisfaction, relational (interactions with provider's staff) environment (service facilities), market shares components Using multiple...

ABSTRACT Product recalls are often associated with quality failures and may negatively affect customer satisfaction firm performance. Motivated by counterintuitive anecdotal evidence on the positive relationship between sales, we develop an endogenous consumer reference model stochastic levels valuation of gain‐loss utility to examine consumer's willingness buy in event a recall. A makes purchasing decisions evaluating values against point. The theory points incorporates expectations buying...

Crowdfunding has emerged as a market-based solution to give frontline complex public service employees the opportunity acquire resources by advertising project proposals for donor patrons on crowdfunding platforms. However, whether crowdfunded can improve offline outcomes, and if so, how when, remains murky. Focusing context of education applying theories from services marketing literature, authors conceptualize that combination two factors—namely, teachers’ request meant satisfy unmet...

With more and Web services appearing on the Web, service’s discovery mechanisms become essential. UDDI is an online registry standard to facilitate of business partners services. Service requesters can choose good performance by manual test comparison. However, this method choosing inefficient costly in terms time money. The ability predict quality service missing UDDI. Furthermore, registries federated organizations should be able share about requester’s connection information make better...

With the industry's efforts in promoting use of Web services, a huge number services are being developed for Web. To improve service provider's competition advantage, it is necessary to support QoS-aware discovery mechanism as well corresponding measurement system. In this paper we present QoS framework based on DAML-QoS ontology, together with code generator. The ontology designed specify constraints services. It works complement DAML-S provide discovery. This focuses its check runtime...

As more and Web services are deployed, service's discovery mechanisms become essential. Similar can have quite different QoS behaviors. For service selection management purpose, it is necessary to clearly specify constraints metrics definitions for services. We investigate on the semantic specification introduce our design principles it. Based refinement conformance, we matchmaking algorithm with multiple matching degrees. The prototype designed prove feasibility. Well-defined Metrics be...

Kitting is the process that gathers all of components necessary to assemble a batch circuit boards on production machines. An objective in kitting storage design minimize travel involved collecting area so as decrease labor costs. From outward appearances, similar order picking warehouse. Closer observation, however, reveals its unique characteristics favor cluster-based allocation over strategies usually adopted warehouses. We present clustering and cluster assignment method. In method we...
