Remote Technical Support Needs for Hospital Personnel : Using Q-methodology to Examine Remote Support Solutions in Healthcare / Behoven av fjärrstyrda tekniska supportlösningar för sjukvårdspersonal : En tillämpning av Q-metodologi för att undersöka fjärrstyrda tekniska supportlösningar i sjukvårdenFendukly, Mattias January 2018 (has links)
Remote control and management functions are widely utilized in multiple industries.The remote control and management functions has allowed for peopleto connect and interact to solve technical problems more efficiently. However,the healthcare organizations have not utilized the remote controlling and managementfunctions to a degree similar to other industries. Telephoning ande-mailing are still two mainstream ways of work when it comes to solvingtechnical support issues in-house. In order to understand what the technicalpersonnel and the clinical users at a hospital desires in new solutions, thismaster thesis project aimed at finding the existing needs in terms of remotecontrolling and management functions. To find these needs, Q-methodologywas applied for collection of subjective data from healthcare personnel abouta software device that aims at providing remote controlling and managementfunctions. In addition to finding and defining the needs, this thesis also aimedat examining how well such systems can address these needs. Performing this methodology three factors where found representing three differentattitudes regarding the needs for remote functions. The three factorsare "Technical Communication is Significant", "Functionality Appreciativeand Experienced" and "Do if fast!". These factors and their interpretationhelps to be aware of and to evaluate remote support solutions in a systematicway. / Tillämpningen av tekniska distanslösningar används i flertalet industrier i olika syften. Dessa tillämpningar har möjliggjort att människor kan ansluta och interagera med varandra för att på ett effektivt sätt lösa tekniska problem. Trots detta har inte vårdgivarorganisationer tillämpat dessa typer av lösningar i en liknande utsträckning jämfört med många andra industrier. Kommunikationskanaler som telefonsamtal och e-post är fortfarande vanliga när vårdpersonal bemöter tekniska problem som ska lösas internt. Syftet med denna uppsats är att hitta och definiera de befintliga behov som teknisk personal och kliniska användare upplever på sjukhus gällande tekniska distansl ösningar. För att hitta och definiera dessa behov har Q-methodology tillämpats för att systematiskt samla subjektiv data från vårdpersonal gällande ett nytt verktyg som ämnar till att leverera tekniska distanslösningar till sjukvården. Utöver detta har denna uppsats också undersökt hur väl denna typ av nya verktyg tillfredsställer de adresserade behov som beskrivits ovan. Applicerandet av denna metodik resulterade i tre åsiktsgrupper som representerar tre olika attityder gällande behov för tekniska distanslösningar. Dessa tre åsiktsgrupper är "Technical Communication is Signficant", "Functionality Appreciative and Experienced" och "Do it fast! ". Vetskapen om dessa existerande_åsiktsgrupper bidrar till en större förståelse och en större förmåga att utvärdera tekniska distanslösningar.

A muse of fire : British trench warfare munitions, their invention, manufacture and tactical employment on the Western Front, 1914-18Saunders, Anthony James January 2008 (has links)
The emergence of static warfare on the Western Front in late 1914, encouraged the reinvention of devices associated with siege warfare and the invention of hitherto unknown munitions. These munitions included hand and rifle grenades and trench mortars and their ammunition. At the outbreak of war, the British effectively possessed none of these devices and lacked an infrastructure by which they could be quickly designed, manufactured and supplied to the BEF. The British met this challenge with considerable success and the subsequent proliferation of trench warfare munitions had profound consequences for the evolution of British tactics on the Western Front. This thesis examines the processes by which these devices were invented, developed into manufacturable devices and supplied to the BEF. It considers their novelty in respect to similar devices from the American Civil War and the Russo-Japanese War. It looks at how their technical evolution affected tactical developments. The thesis discusses the relationship between the technical characteristics of these devices and the evolution of their tactical employment on the Western Front. It also considers how the characteristics of certain munitions, such as the Stokes mortar and the Mills grenade, directly effected tactics. It argues that the tactical employment of these munitions was dependent upon their functionality, utility and reliability. The present thesis provides a different model of trench warfare conducted by the British during the First World War and thereby demonstrates the significance of the novel munitions under discussion and the role they played in changing infantry warfare. This thesis also provides a different view of the Ministry of Munitions from that usually offered and argues that certain aspects of the Ministry’s role in providing the BEF with munitions has been overstated by virtue of its having underplayed the work of the War Office, while overlooking that conducted by the Royal Engineers in France.

Rechnergestützte Planung und Rekonstruktion für individuelle Langzeit-Knochenimplantate am Beispiel des UnterkiefersSembdner, Philipp 29 March 2017 (has links) (PDF)
Die vorliegende Arbeit befasst sich mit der Entwicklung und Umsetzung von Methoden und Werkzeugen zur Bereitstellung von Modellen und Randbedingungen für die Konstruktion individueller Langzeit-Knochenimplantate (Konstruktionsvorbereitung). Grundlage dabei ist, dass die Planung aus medizinischer Sicht z.B. durch einen Chirurgen und die Konstruktion unter technischen Aspekten z.B. durch einen Konstrukteur getrennt erfolgt.
Hierfür wird ein erarbeitetes Planungskonzept vorgestellt, welches sowohl die geplanten geometrischen Merkmale, als auch weiterführende Metadaten beinhaltet (Randbedingungen). Die Übergabe dieser Planungsdaten an die Konstruktion erfolgt über eine dafür entworfene Formatbeschreibung im Kontext der Schnittstelle zwischen Mediziner und Ingenieur. Weiterführend wird die Notwendigkeit von speziellen Funktionen für die Konstruktion von individuellen Implantaten in der Arbeitsumgebung des Konstrukteurs (z.B. Modelliersystem – CAD) am Beispiel der konturlinienbasierten Modellrekonstruktion erörtert.
Die gesamtheitliche Basis bildet eine durchgängig digitale Prozesskette zur Datenaufbereitung, Konstruktion und Fertigung. Die Anwendbarkeit der Methoden und zweier umgesetzter Demonstratoren wurde innerhalb eines interdisziplinär angelegten Projektes am realen Patientenfall bestätigt.

Utveckling av lastutrymme för ett konceptfordon : Utvecklingsprojekt för den designmässiga utformningen av ett måttdefinerat lastutrymme / Development of Boot Compartment for a concept vehicle : Development project for the design layout of a measure defined boot compartmentÅkerman Markgren, Marcus January 2016 (has links)
Den här rapporten behandlar ett utvecklingsprojekt med mål att framställa ett designförslag på utformingen av ett måttdefinerat lastutrymme. Detta sker inom ramen av ett examensarbete, omfattande 22,5 hp, som en del i högskoleingenjörsprogrammet inom innovationsteknik och design på Karlstads universitet. Uppdragsgivare är Martin Larsson, vd på Precer Autotech, ett företag som utvecklar en ny typ av hybridfordon som drivs av fastbränslen. Detta fordon har dimensionerna av en normalstor personbil, men klassas som en motorcykel, eller fyrhjuling. I och med detta har fordonet i fråga speciella faktorer att förhålla sig till när det gäller bl.a. förhållandet mellan vikt och storlek. Utvecklingen av lastutrymmet är ett projekt som är med och utvecklar en grund för det framtida konceptfordon som utav Precer Autotech ska utvecklas. Den industriella designprocessen har genomsyrat projektet och metoder tillhörande denna process har betonats. Metoder såsom användningen av en fullskalig mock-up har gett detta projekt en särprägel. Från idégenereringar till konceptutvecklingar har projektet använt sig av metoder och tillvägagångssätt vilka betonats i projektansvariges universitetsutbildning. Resultatet från detta projekt har mynnat ut i ett helhetskoncept för utforming av det måttbestämda lastutrymmet, som visat sig uppfylla de krav som ställdes på den slutgiltiga konceptlösningen. Denna slutgiltiga konceptlösning har utarbetats i en fullskalig mock-up, vilket också har varit en del av projektets mål. / This report covers a development project which goal is to produce one or more layout concepts of a measure defined boot compartment. This project is conducted as Bachelor of Science thesis within the bachelor engineering program of innovation technics and design in Karlstad University, Sweden. The assignment was supplied by Martin Larsson, managing director at Precer Autotech, a company that is developing a new type of hybrid vehicle that runs on solid fuels. This vehicle owns the dimensions of an average sized car, though is technically defined as a larger sized quad or ATV. Because of this, the vehicle in question is subject to several special factors regarding, for example, the ratio between weight and size. The project is going to provide part of the foundation on which this concept vehicle will be developed. The process of industrial design has pervaded this project, with methods and techniques originated from said process riddling the entirety of the project. Methods such as the use of a full scale mock-up have nuanced this project. From sessions of brainstorming to the development of concepts, this project has been using techniques and ways which has been a defining part of the university studies. The project resulted in one concept for totality of the measure defined boot compartment, which has shown to fulfill the demands of the project. The final concept solution has also been implemented in a full scale mock-up, which was a part of the project’s goals. / Utveckling av lastutrymme för ett konceptfordon

Product structure modeling for ETO system product considering the product lifecycle : A case study of ABB Mine HoistZhang, Sumei January 2019 (has links)
In order to gain competitive advantages in markets, companies have provided a variety of customized products to satisfy customer-specific requirements, leading to not only a large amount of product data but also high cost, long lead-time and complexity of quality control. Efficient product data management throughout the product lifecycle has become increasingly crucial, of which product structure management is regarded as the most important constituent. The study took ABB Mine Hoist system as a case to investigate how to construct a generic product structure model fit for engineer-to-order system offerings with the consideration of their sales-delivery product lifecycle. The aim of the model is to facilitate the product-related information sharing and reuse across a company, and the integration of different business operations throughout the entire product lifecycle as well. Based on the current situation analysis of product data management on ABB Mine Hoist, three major issues were identified which need to be addressed in the formulation of a generic structure model: namely the integration of requirements of multiple disciplines; the consistency of product information throughout the product lifecycle; and the constant update of product repository. Through illustrating the formulation of ABB Mine Hoist generic structure model, the method of how to construct a generic product structure model for engineer-to-order system product was presented. The model was achieved by applying the framework of the step-based product model and was regarded as a result of integrating domain-specific requirements. The adaptive generic product structure model was then employed to display the role of this generic model in the different phases of a sales-delivery lifecycle. The model could serve as a “master concept” to transfer common product information in the product lifecycle. It’s expected to benefit the business of engineer-to-order system product through improving the integration of different disciplines, enhancing information exchange and reuse. It could also provide an abstract and conceptual basis for potential product repository to reinforce data consistency and completeness.
