Guidelines for evaluating the ease of reconfiguration of manufacturing systems

This paper presents guidelines for evaluating the ease of reconfiguration of manufacturing systems. Based reconfigurability measurement tools proposed in the past [1], [2]and a reconfiguration process model, the paper proposes a method that can be used to assess different system characteristics. After the guideline is presented, an example of how the method can be applied to a batch processing system is given. It is found that the proposed method can be applied to batch processing systems based on ISA S88 batch server commercial software. ©2008 IEEE.

Design guidelines for granular particles in a conical centrifugal filter

Essential design criteria for successful drying of granular particles in a conical continuous centrifugal filter are developed in a dimensionless fashion. Four criteria are considered: minimum flow thickness (to ensure sliding bulk flow rather than particulate flow), desaturation position, output dryness and basket failure. The criteria are based on idealised physical models of the machine operation and are written explicitly as functions of the basket size lout, spin velocity Ω and input flow rate of powder Qp. The separation of sucrose crystals from liquid molasses is taken as a case study and the successful regime of potential operating points (lout, Ω) is plotted for a wide range of selected values of flow rate Qp. Analytical expressions are given for minimum and maximum values of the three independent parameters (lout, Ω, Qp) as a function of the slurry and basket properties. The viable operating regime for a conical centrifugal filter is thereby obtained as a function of the slurry and basket properties. © 2012 The Institution of Chemical Engineers.

Numerical modelling of chirality-Induced bi-Directional swimming of artificial flagella

Biomimetic micro-swimmers can be used for various medical applications, such as targeted drug delivery and micro-object (e.g. biological cells) manipulation, in lab-on-a-chip devices. Bacteria swim using a bundle of flagella (flexible hair-like structures) that form a rotating cork-screw of chiral shape. To mimic bacterial swimming, we employ a computational approach to design a bacterial (chirality-induced) swimmer whose chiral shape and rotational velocity can be controlled by an external magnetic field. In our model, we numerically solve the coupled governing equations that describe the system dynamics (i.e. solid mechanics, fluid dynamics and magnetostatics). We explore the swimming response as a function of the characteristic dimensionless parameters and put special emphasis on controlling the swimming direction. Our results provide fundamental physical insight on the chirality-induced propulsion, and it provides guidelines for the design of magnetic bi-directional micro-swimmers. © 2013 The Author(s) Published by the Royal Society.

博兴洼陷西部砂体成因与油气成藏研究

Based on achievements of thirty years of hydrocarbon exploration, this paper uses the modern theories and methods of sedimentology and oil accumulation to study the origin and distribution features of four sandbodies of Gaoqing, Fanjia, Zhenglizhuang and Jinjia from the third member to the lower second member of Shahejie Formation in detail. Various geophysical methods are also used to explain and to predict the spatial distribution of sandbodies, which further shows mechanism and the model of oil accumulation and illuminates the disciplinarians of oil enrichment and its controlling factors in the study area. The most favourable oil pools predicted by this paper have significant economic and social benefits, which has been confirmed by the exploration. The main conclusions and knowledge includes: (1) Resolving the problems, which remain unresolvable for a long time in the western area of Boxing depression, about the original environment and the spatial distribution of sandbodies of Gaoqing, Fanjia, Zhenglizhuang and Jinjia, and illuminating their relationships. It is suggested that two deltas or delta-related sandbody sediments, which include the delta sandbodies of Jinjia and Gaoqing and their frontal turbidite fan sandbody, are developed in the second and third members of Shahejie Formation. The sandbodies of Fanjia, Gaoqing and Zhenglizhuang are components of Gaoqing delta and belong to the sediments of various periods in different part of the delta. Whereas, the sandbody of Jinjia belong to the Jinjia delta or fan-delta created by the uplift of the Western Shandong and in some areas shows the features of juxtaposition, superimposed deposition and fingeration with the sandbodies of Gaoqing and Zhenglizhuang. (2)Proposing that the sandbodies of different origins in the deltas of Gaoqing and Jinjia have obvious different reservoir qualities, among which the delta frontal bedded sandbodies in the second member of Shahejie Formation in Zhenglizhuang are the best ones and the turbidite sandbody of Fanjia is relatively worse. This shows the direction of further reservoir prediction. (3) According to modern petroleum system theory and continental pool-formation theory, the author divided the western area of Boxing depression into the Jinjia—Zhenglizhuang—Fanjia nose structure belt pool-formation system and the Gaoqing fracture belt pool-formation system. The study area is predominantly located in the former belt and subdivided into pool-formation sub-systems of Zhenglizhuang-Fanjia and Jinjia, which have the source rock of mudstone and oil shale from the upper forth member and the third member of Shahejie Formation in Boxing depression. The hydrocarbon migration and accumulation are controlled by Jinjia-Zhenglizhuang-fanjia nose structure and Gaoqing fracture. (4)Proposing that compared with the best developed sandbodies and traps in the west area of Boxing, the source from the Boxing depression is not sufficient, which is the fundamental reason that the hydrocarbon resources in mid-west area is less than in the east of Boxing. (5) Under the direction of the new theory (fluid compartments theory) and new method of modern pool-formation mechanism, two kinds of pool-formation model are established in study, i.e. inner-compartment model and outer-compartment model. The former has abnormal pressure and is the antigenic source seal pool-forming mechanism, whereas the latter has normal pressure and is of the allochthonous source opening pool-formation mechanism. (6)The study shows that the four sandbodies of Gaoqing, Fanjia, Jinjia and Zhenglizhuang sand are all very benefit for pool-formation, among which the Fanjia sandbody is the best favourable one and is likely to form lithological reservoir and fault-lithological reservoir. But the main step of exploration in Gaoqing, Zhenglizhuang sandbodies should be finding out the fault block, reversed roof and stratum-lithological oil reservoir. (7)Established a set of guidelines and techniques for the research and exploration in the large scale of sandbodies. Proposing that the various traps related to reversed fault and basin-ward fault should be found in step slopes and gentle slopes respectively, and the lithological oil reservoir should mainly be found in the sandstone updip pinch out. It is also suggested that Fanjia sandbody is most favourable to form the lithological and fault-lithological and the Gaoqing, Zhenglizhuang and Jinjia sandbodies have the potential of forming fault block, reversed roof and stratum-lithological oil reservoir. (8) Interpretation and prediction the spatial distribution of main sandbodies based on various geophysical methods suggestion that Fanxi, Gao28 south and Gao27 east have better exploration potential.

Guidelines on the management of implantable cardioverter defibrillators at the end of life

El presente artículo es un documento conjunto de la Sociedad Española de Geriatría y Gerontología, la Sociedad Española de Cuidados Paliativos y la Sección de Cardiología Geriátrica de la Sociedad Española de Cardiología. Su objetivo es paliar la laguna que existe en España en lo que respecta al manejo de los desfibriladores automáticos implantables (DAI) en las fases finales de la vida. Cada vez es más frecuente encontrarse enfermos portadores de DAI en fase terminal de una enfermedad avanzada, como insuficiencia cardíaca refractaria, enfermedades oncológicas, otras insuficiencias orgánicas o enfermedades neurodegenerativas con mal pronóstico a corto plazo. La enorme mayoría de estos pacientes tiene más de 65 años, por ello el documento se enfoca de forma particular a los ancianos que se encuentran en esta situación, aunque el proceso de toma de decisiones es similar en portadores de DAI más jóvenes que están en la fase final de su vida.

Elicitation techniques for the evaluation of speech under stress: Towards a framework for use in a controlled environment

Existing work in Computer Science and Electronic Engineering demonstrates that Digital Signal Processing techniques can effectively identify the presence of stress in the speech signal. These techniques use datasets containing real or actual stress samples i.e. real-life stress such as 911 calls and so on. Studies that use simulated or laboratory-induced stress have been less successful and inconsistent. Pervasive, ubiquitous computing is increasingly moving towards voice-activated and voice-controlled systems and devices. Speech recognition and speaker identification algorithms will have to improve and take emotional speech into account. Modelling the influence of stress on speech and voice is of interest to researchers from many different disciplines including security, telecommunications, psychology, speech science, forensics and Human Computer Interaction (HCI). The aim of this work is to assess the impact of moderate stress on the speech signal. In order to do this, a dataset of laboratory-induced stress is required. While attempting to build this dataset it became apparent that reliably inducing measurable stress in a controlled environment, when speech is a requirement, is a challenging task. This work focuses on the use of a variety of stressors to elicit a stress response during tasks that involve speech content. Biosignal analysis (commercial Brain Computer Interfaces, eye tracking and skin resistance) is used to verify and quantify the stress response, if any. This thesis explains the basis of the author’s hypotheses on the elicitation of affectively-toned speech and presents the results of several studies carried out throughout the PhD research period. These results show that the elicitation of stress, particularly the induction of affectively-toned speech, is not a simple matter and that many modulating factors influence the stress response process. A model is proposed to reflect the author’s hypothesis on the emotional response pathways relating to the elicitation of stress with a required speech content. Finally the author provides guidelines and recommendations for future research on speech under stress. Further research paths are identified and a roadmap for future research in this area is defined.

The aim of this paper is to contribute to the increase in the level of care in a breast unit, as the input of qualified health professionals increases the quality of breast cancer patient care.

Clinical practice guidelines for the management of cryptococcal disease: 2010 update by the infectious diseases society of america.

Cryptococcosis is a global invasive mycosis associated with significant morbidity and mortality. These guidelines for its management have been built on the previous Infectious Diseases Society of America guidelines from 2000 and include new sections. There is a discussion of the management of cryptococcal meningoencephalitis in 3 risk groups: (1) human immunodeficiency virus (HIV)-infected individuals, (2) organ transplant recipients, and (3) non-HIV-infected and nontransplant hosts. There are specific recommendations for other unique risk populations, such as children, pregnant women, persons in resource-limited environments, and those with Cryptococcus gattii infection. Recommendations for management also include other sites of infection, including strategies for pulmonary cryptococcosis. Emphasis has been placed on potential complications in management of cryptococcal infection, including increased intracranial pressure, immune reconstitution inflammatory syndrome (IRIS), drug resistance, and cryptococcomas. Three key management principles have been articulated: (1) induction therapy for meningoencephalitis using fungicidal regimens, such as a polyene and flucytosine, followed by suppressive regimens using fluconazole; (2) importance of early recognition and treatment of increased intracranial pressure and/or IRIS; and (3) the use of lipid formulations of amphotericin B regimens in patients with renal impairment. Cryptococcosis remains a challenging management issue, with little new drug development or recent definitive studies. However, if the diagnosis is made early, if clinicians adhere to the basic principles of these guidelines, and if the underlying disease is controlled, then cryptococcosis can be managed successfully in the vast majority of patients.
