Purpose – This article aims to analytically review the Plan-Do-Study-Act (PDSA) model used in the Pacesetters national programme evaluation. Design/methodology/approach – The evaluation team's two-fold role is outlined: supporting project teams to develop PDSA plans and collect evaluation data. Four case studies are used to show the PDSA model's application and effect in a participatory action learning approach. Despite limitations, it is clear that all four case studies illustrate the PDSA model's potential benefits in a participatory evaluation approach, which involves public and patients. F

It is argued that a project system consists of two interacting subsystems: a project structure subsystem (PSS) and a project delivery subsystem (PDS).

Abstract:
AbstractGiven the versatility of timed automata a huge body of work has evolved that considers extensions of timed automata. One extension that has received a lot of interest is timed automata with a, possibly unbounded, stack, also called pushdown timed automata (PDTA). While different algorithms have been given for reachability in different variants of this model, most of these results are purely theoretical and do not give rise to efficient implementations. One main reason for this is that none of these algorithms (and the implementations that exist) use the so-called zone-based abstraction, but rely either on the region-abstraction or other approaches, which are significantly harder to implement.In this paper, we show that a naive extension, using simulations, of the zone based reachability algorithm for the control state reachability problem of timed automata is not sound in the presence of a stack. To understand this better we give an inductive rule based view of the zone reachability algorithm for timed automata. This alternate view allows us to analyze and adapt the rules to also work for pushdown timed automata. We obtain the first zone-based algorithm for PDTA which is terminating, sound and complete. We implement our algorithm in the tool TChecker and perform experiments to show its efficacy, thus leading the way for more practical approaches to the verification of timed pushdown systems.

Abstract:
This chapter offers an introduction to the recently developed applied health science fields of patient safety, improvement, and implementation sciences. Healthcare is a high-risk activity because of the complexity of its systems and processes. Errors arise frequently and these can impact negatively on patients by causing adverse events. Errors and adverse events are generally attributable to defective systems for organizing care, which create conditions in which errors arise. This represents a failure of risk management. Patient safety science takes a scientific approach to understanding why errors occur and how to prevent their occurrence or minimize their impact. Learning from analysis of patient safety incidents, through root-cause analysis, enables an organization or service to learn and avoid repeating similar failures in the future. Patient safety incidents represent one aspect of the wider problem of poor-quality care. Improvement science offers standardized tools and measurements that can be used to monitor and improve healthcare delivery. The Model for Improvement employs repeated Plan–Do–Study–Act (PDSA) cycles to quantify problems and to develop and test potential solutions. Engagement with stakeholders is an essential part of this process. Implementation science can contribute by providing methods to promote the uptake of new research evidence into healthcare practice. It can address the second translational gap by facilitating the widespread adoption of strategies for improving health-related processes and outcomes, and advancing knowledge on how best to replicate intervention effects from trials into real-world settings. These new scientific fields provide well-established approaches to addressing some of the key problems arising in healthcare. Modern public health needs to reap the benefits of these newly emerged sciences to address the burden of adverse events and harm that arises in the delivery of healthcare and to promote evidence-based practice.

Abstract:
Since 1984, remote controlled continuous mining machines (CMM) have caused 40 crushing and pinning fatalities in the United States. Due to limited space in the underground environment and visibility needs, CMM operators typically work close to the machine which exposes them to the danger of being struck or pinned by it. Because of these fatalities, the Mine Safety and Health Administration (MSHA) has published a rule requiring proximity detection systems (PDSs) on all CMMs except for full-face machines. To test PDS performance, researchers at the National Institute for Occupational Safety and

Abstract:
Abstract The work addresses the problem of the fast and accurate calculation of the mathematically stiff hydraulic models using the modified pseudo-dynamic solver (PDS). In particular, it studies which of the numerical integration methods inside the modified PDS ensure efficient calculation of the stiff hydraulic model. In the work, the operating principle of the modified PDS is described. The effect of the three different fixed-step integration methods (Euler, Runge-Kutta of fourth order, and modified Heun’s method) are considered. The numerical stability of the modified Heun’s method is impr

Abstract:
The numerical approach using the multi-frequency one-dimensional whirling orbit model and Reynolds-Averaged Navier-Stokes (RANS) solution was proposed for prediction of rotordynamic coefficients of pocket damper seal (PDS). By conducting the multiple frequencies one-dimensional whirling orbit for rotor center as the excitation signal, the unsteady RANS solutions combined with mesh deformation method were utilized to calculate the transient response forces on the PDS rotor surface. Unlike the single frequency whirling orbit models which require a separate computation for each frequency, the mul

Abstract:
Abstract High performance centrifugal compressors presently favor pocket damper seals (PDSs) as a choice of secondary flow control element offering a large effective damping coefficient to mitigate rotor sub synchronous whirl motions. Current and upcoming multiple-phase compression systems in subsea production facilities must demonstrate long term operation and continuous availability, free of harmful rotor instabilities. Plain annular seals and labyrinth seals are notoriously bad choices, whereas a PDS, by stopping the circulation of trapped liquid, operates stably. This paper presents experi
