Application of Empirical Orthogonal Function Models to Analyze Shoreline Change at Bangkalan Madura

Bangkalan’s shoreline, especially on the opposite side of Surabaya, has been evaluated to determine the morphological changes due to wave attack, near-shore current, long-shore sediment transport and coastal configuration. This research aims to determine the dominant patterns of variation of Bangkalan’s shoreline change, expressed by Eigen-function in empirical orthogonal function (EOF) models. That was started with data collection such as oceanographic data (wave and tidal), bathymetry and topographic map and sediment data. All data was used for forecasting two-monthly shoreline. Coordinate of two-monthly shoreline was used as input of EOF model. The first Eigen mode is a profile of shoreline equilibrium. The second Eigen mode shows pivot point that separates the different behaviors, which indicates a positive balance of shoreline from the direction of the dominant force. The models execution based on 1986’s shoreline show the shoreline change significantly at some cells e.g. around Suramadu bridge (cell 1-40), Batuporon (cell 70-100), Jungdima (cell 142-170) and at Kamal port (cell 230-250). The model of shoreline change using EOF was validated with the One-line model and data of 1995’s map’s shoreline. The E.O.F. value of model RMSE, 0.02, is less than the root mean square error (RMSE) value of One-line model, 0.04, which shows that the EOF model performance better than One-line models

Investigating the relationships between peristaltic contraction and fluid transport in the human colon using Smoothed Particle Hydrodynamics

© 2012. This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/Complex relationships exist between gut contractility and the flow of digesta. We propose here a Smoothed Particle Hydrodynamics model coupling the flow of luminal content and wall flexure to help investigate these relationships. The model indicates that a zone of muscular relaxation preceding the contraction is an important element for transport. Low pressures in this zone generate positive thrust for low viscosity content. The viscosity of luminal content controls the localization of the flow and the magnitude of the radial pressure gradient and together with contraction amplitude they control the transport rate. For high viscosity content, high lumen occlusion is required for effective propulsion

Economie politique de la LOLF.

La loi organique sur les lois de finances (LOLF), adoptée en 2001, est pleinement mise en application depuis janvier 2006. Cette loi s'inscrit dans un mouvement visant « à substituer un fonctionnement managérial à un fonctionnement juridique » basé sur deux grands principes : l'amélioration de la gestion publique et la transparence. Moins d'un an après la pleine mise en oeuvre de la LOLF et un an après le démarrage des audits de modernisation, ministère par ministère, qui l'accompagnent, ce rapport vise à souligner les enjeux de la réforme budgétaire pour l'État, pour l'organisation administrative et le management public, mais aussi pour l'économie française. Quatre questions sont successivement abordées, avec à l'appui des compléments figurant en annexe de ce rapport et rédigés par différentes personnalités : quels sont les principaux fondements de la réforme budgétaire ? Quelles leçons tirer des expériences menées en la matière à l'étranger ? Quels sont les principaux apports et défis de la LOLF ? Quelles principales recommandations déduire de ce « voyage » dans le nouvel espace budgétaire français ?This report focuses on the principles presiding over the implementation of the LOLF, which, the authors note, is part of a movement towards ‘the substitution of managerial functioning for legal functioning’ based on two major principles: the improvement of public sector management and transparency.LOLF;

Living with Quadriplegia: A Journey of Personal and Professional Development

In this article, I provide an autoethnographic account of the discursive and narrative changes I have experienced and the agency I have found, following an accident thirty-seven years ago that resulted in permanent spinal cord injury. Initially losing my career and identity as a farmer, my hope and survival depended on adopting new frameworks of understanding – both in terms of the physical realities of living with incomplete quadriplegia and in becoming subjectively positioned quite differently than I was as an able-bodied male with farming knowledge and skills. In more recent years, as my spinal health and mobility have deteriorated, the challenge has shifted to maintaining a sense of agency when many daily activities have become increasingly difficult or no longer independently possible. Given these meaning-making shifts and associated personal and professional development I have engaged in since the spinal injury, my narrative could perhaps be described as a hero’s journey

Measurement of Muscular Activity Associated With Peristalsis in the Human Gut Using Fiber Bragg Grating Arrays

Author version made available under Publisher copyright policy.Diagnostic catheters based on fibre Bragg gratings (FBG’s) are proving to be highly effective for measurement of the muscular activity associated with peristalsis in the human gut. The primary muscular contractions that generate peristalsis are circumferential in nature; however, it has long been known that there is also a component of longitudinal contractility present, acting in harmony with the circumferential component to improve the overall efficiency of material movement. We report on the development of, and latest results from, catheter based sensors capable of detecting both forms of muscular activity. While detection of the circumferential contractions has been possible using solid state, hydraulic, and pneumatic sensor arrays in the oesophagus and anorectum, FBG based devices allow access into the complex and convoluted regions of the gut below the stomach. We report early results from FBG catheters used during trials of novel therapies in patients with both slow transit constipation and faecal incontinence. In addition, there have been relatively few reports on the measurement or inference of longitudinal contractions in humans. This is due to the lack of a viable recording technique suitable for real-time in-vivo measurement of this type of activity over extended lengths of the gut. We report preliminary data on the detection of longitudinal motion in lengths of excised mammalian colon using an FBG technique that should be viable for similar detection in humans. The longitudinal sensors have been combined with pressure sensing elements to form a composite catheter that allows the relative phase between the two components to be detected. The output of both types of catheter has been validated using digital video mapping in an ex-vivo animal preparation using lengths of rabbit ileum

Going to the Zoo: Using Tags to Create Measures for Animal Health, Well-being and Welfare in a Managed Care Setting

This PhD investigates how animal-attached motion-sensitive electronic tags might create behavioural biomarkers for animal ‘state’. Such biomarkers could indicate good health, disease, and injuries as well as positive and negative affective states. Success could have widespread implications for the well-being of numerous species in managed care by optimising welfare practices. This work primarily involved loggerhead sea turtles, Caretta caretta, in different states of health at the Arca del Mar rehabilitation centre, Oceanogràfic, Valencia, Spain, however the potential of tags for various aquatic, aerial and terrestrial species is also considered. Initially, the concept of tag-derived behavioural biomarkers for health (TDBBs) was established, examining data from ‘healthy’ and ‘unhealthy’ rehabilitating sea turtles to identify potentially useful metrics for specific injuries and/or diseases. Then, potential TDBBs for ‘healthy’ turtles and those with gas emboli were created, with variance in body attitude, number of 45° turns per hour and mean angular velocity per hour showing the most promise to differentiate the two groups. TDBBs were also explored for welfare, giving ‘healthy’ turtles nutritional enrichment, demonstrating that enrichment procedures do not always affect captive animal behaviour. To consider welfare implications of captivity, the movement behaviour of free-living and managed-care loggerheads was compared to determine wild-type and captive behaviour overlap. Findings revealed significant differences in the variance in pitch, heading and absolute angular velocity as well as the number of turns per hour. The final research topic considered trajectory step length data (the distances travelled in between turns), derived from tags deployed on nine wild species, for informing enclosure size for captive animals. The findings revealed that existing enclosure size guidelines regularly only permitted animals to undertake a very small percentage (often less than 3 %) of the step lengths recorded from free-living conspecifics. Last, the potential of TDBBs is reviewed, with limitations and future research discussed

Discourse, Narrative and Agency: A Contribution of Local Stories to Disability Theory, Research and Professional Practice

The impetus for this study arose from a realisation that the post-structural concept of agency was relevant to disability studies. In locating this study as a contribution to the knowledge of disability and disablement, the initial chapters explore the theoretical genealogy of disability studies and the methodology for the study. In broad terms this has been a discursive and narrative research project, which sought to explore how discourse constituted the lives of six people with impairments and/or illness. Within this examination, specific attention was paid to those occasions in which the participants were able to take up alternative and preferred subject positions when they had been positioned in ways that removed or reduced their agency on account of their having an impairment and/or illness. The six people who participated in the study are introduced at the end of Chapter Four and the next three chapters provide an account of their accounts. Overall, the participants’ accounts of their experiences told how medical discourse positioned them in ways that removed their agency but not exclusively so. In contrast to medical discourse, disability rights discourses offered alternative subject positions because disablement is not constructed as an inevitable consequence of having an impairment and/or illness. In regard to the benefit of disability rights discourses for disabled people, two of the participants had been advantaged by the career opportunities available to them within the disability sector that arguably had been created by disability rights discourses. However, generally speaking, the participants’ accounts of their experiences showed that disability rights discourses were not the only discursive option for them. On those occasions in which the participants took up subject positions that afforded them agency, they were often calling on more than one discursive idea or practice, typically beyond both medical or disability rights discourse. The participants’ lives were more diverse and complex than the reproduction of any one singular discourse. Hence, even between just six people’s accounts, there was significant difference between how each person called on and negotiated discourse so as to take up subject positions that offered them agency. In considering the participants’ accounts, a number of generic storylines have been generated from the research process. In particular, these were: the negative impact of deficit discourse on disabled people’s lives, the advantages and limitations of disability rights discourses, the complex and person-specific processes of taking up subject positions that afford agency for the person, and the experience of silenced, subjugated and contradictory subject positions. These quite specific understandings about the processes of disablement for people who have impairments and/or illnesses, and their corresponding actions of agency, are discussed in more detail in the concluding chapter in regards to implications for future research, theory and professional practice

Design of an Active-Control Pressure Regulator for a Rocket

An electronically actuated pressure-regulation valve and controller are necessary for maintaining pressure levels in a pressure-fed liquid-fueled rocket engine. Mechanical regulators are too heavy and have unacceptably high-pressure variation throughout the operation of a dynamic system like a rocket. Developing an electronic pressure regulator using a PID controller is a method by which a reliable, accurate, and lightweight flow regulator can be built for use on a rocket vehicle. This work will outline the development of flow simulations, PID controller, physical valve hardware, and initial testing
