Abstract:
The aim of this research is to propose and develop an analytical exact solution for finding the static equilibrium configuration of a catenary before and after incurring defects such as tension loss or a broken dropper. The procedure includes considering the steady-state solution of the dynamic motion equation of the contact wire and the messenger cable. The wire and the cable are considered as tensile Euler–Bernoulli beams. The stiffness matrix of the beam is configured and is used to calculate the dropper's dead load. Progressively, a novel method is proposed to find the equilibrium configuration of the same catenary after the defect. The results prove that the tension loss in the messenger cable is more precarious than the tension loss in the contact wire. The broken dropper causes a significant sag in the sub-span and increases the static forces of the adjacent droppers. A comparison with field measurements justifies the accuracy of the results of the proposed model.

This paper presents a device to investigate dielectrophoresis (DEP) effects through different patterns of the electrodes. Pattern of electrodes, DEP time and voltage have been described to research the manipulation of particles by dielectrophoresis. The TiO2sample droplet was dropped onto several electrode pairs using a micro-dropper. We succeeded in manipulating TiO2particles along the electric field and deposited them across the gaps between two electrodes by modulating different factors. SEM images were used to confirm the patterns of different electrodes.

Abstract:
We consider a stochastic dynamic game with uncertainty about appearance of an dropper in infinite time horizon. For the lack of information about whether the dropper is present or not, two different states of nature can appear with some given probabilities at each stage. We study the non-cooperative behavior of players, and Nash equilibrium is considered as an equilibrium concept. We investigate how limited information about the dropper's appearance impacts the anti-jamming strategy.

Abstract:
Dropper is the key component of in a catenary system and it is prone to fatigue fracture. Dropper stress directly affects the operation safety of high-speed railway. In this paper, a span of dropper in a catenary system is modeled to investigate the effects of contact wire tension on dropper stress. The response equation of contact wire and the theoretical equation of dropper stress are deduced. The initial and boundary conditions of each dropper are determined, and then the stress of each dropper is calculated by the finite difference method using a MATLAB program. The results show that the stress amplitude and the maximum tensile stress of the dropper decrease significantly with the increase of contact wire tension. When the tension is low, the stress changes of dropper near the load location experience three stages: instant rebound, attenuated vibration, and bending compression. However, the attenuation vibration stage disappears when the tension is increased to a certain extent. Therefore, the control of the vibration response of the contact wire can effectively reduce the stress amplitude and the maximum tensile stress of the dropper, so as to improve the working reliability of the dropper.

Abstract:
Hydrodynamic effects of mussel farms have attracted increased research attentions in recent years. The understanding of the hydrodynamic impacts is essential for predicting the sustainability of mussel farms. A large mussel farm includes thousands of mussel droppers, and the combined drag on the mussel droppers is sufficient to possibly affect the longevity of the entire long-lines. This article intends to study the drag and wake of an individual long-line mussel dropper using computational fluid dynamics approaches. Two equivalent rough cylinders, namely, Curved-Model and Sharp-Model, have been utilized to simulate the mussel dropper, and each rough cylinder is assigned with surface roughness. The porosity is not considered in this article due to its complexity from inhalant and exhalant of mussels. Two-dimensional laminar simulations are conducted at Reynolds number from 10 to 200, and three-dimensional large eddy simulations are conducted at subcritical Reynolds number ranging from 3900 to [Formula: see text]. The results show that larger drag coefficients and Strouhal numbers are attributed to surface roughness and sharp crowns on the rough cylinder. The obtained drag coefficient ranges from 1.1 to 1.2 with respect to the diameter of the mussel dropper and the peak value of the tidal velocities. Wakes behind rough cylinders fluctuate more actively compared to those of smooth cylinders. This research work provides new insight for further investigations on hydrodynamic interactions between fluid and mussel droppers.

Abstract:
In this paper, the effects of load location on dropper stress are studied. We treat contact wire as a beam element and derive its response equation and then deduce the stress equation of dropper. A computer code based on MATLAB is written to calculate dropper stress using the finite difference method. The results show that there are three stages during the period of the stress changes of dropper, including instant rebound, damped sinusoidal vibration, and bending compression. The shorter the distance away from a load is, the larger the vertical displacement of the dropper is, which results in the corresponding increases of its stress amplitude and the maximum tensile stress. The load location has a significant impact on the stress changes of dropper. Compared to the condition of the load in the middle, the load acting on the edge of contact wire could induce the larger tensile stress when both ends of contact wire are considered as free boundaries. Therefore, it is necessary to add supports at both ends.

Abstract:
Elasticity variations in railway overhead contact line would lead to the fluctuation of contact force between pantograph and contact wire and produce a negative effect on the stability of current collection. Dropper distribution is one of the key factors affecting the elasticity of the contact wire. In this paper, the influence of dropper spacing on elasticity and quality of current collection have been studied using finite element analysis method by simulation. By analyzing the changes of elasticity value and contact force under different conditions of dropper distribution, the effect laws of dropper spacing on the contact wire elasticity and the quality of current collection under the speeds of 300km/h, 350km/h and 400km/h have been obtained.

In a Canadian shopping centre, a mitten or a box of condoms was accidentally dropped in front of 80 individual members of the public. The dropper was helped to retrieve his object by 43% of 30 people who saw the mitten but only by 17% of 30 people who saw the condoms. This replicates Edwards' 1975 report that the rate of helping was lower for an embarrassing than for a neutral object.

Abstract:
Spin-torque transfer (STT) effects have brought spintronics ever closer to practical electronic applications, such as MRAM and active broadband microwave spin-torque oscillator (STO), and have emerged as an increasingly attractive field of research in spin dynamics. Utilizing materials with perpendicular magnetic anisotropy (PMA) in such applications offers several great advantages such as low-current, low-field operation combined with high thermal stability. The exchange coupling that a PMA thin film exerts on an adjacent in-plane magnetic anisotropy (IMA) layer can tilt the IMA magnetization direction out of plane, thus creating a stack with an effective tilted magnetic anisotropy. The tilt angle can be engineered via both intrinsic material parameters, such as the PMA and the saturation magnetization, and extrinsic parameters, such as the layer thicknesses.       STOs can be fabricated in one of a number of forms—as a nanocontact opening on a mesa from a deposited pseudospin-valve (PSV) structure, or as a nanopillar etching from magnetic tunneling junction (MTJ)—composed of highly reproducible PMA or predetermined tilted magnetic anisotropy layers.       All-perpendicular CoFeB MTJ STOs showed high-frequency microwave generation with extremely high current tunability, all achieved at low applied biases. Spin-torque ferromagnetic resonance (ST-FMR) measurements and analysis revealed the bias dependence of spin-torque components, thus promise great potential for direct gate-voltage controlled STOs.       In all-perpendicular PSV STOs, magnetic droplets were observed underneath the nanocontact area at a low drive current and low applied field. Furthermore, preliminary results for microwave auto-oscillation and droplet solitons were obtained from tilted-polarizer PSV STOs. These are promising and would be worth investigating in further studies of STT driven spin dynamics.
Effekter av spinnvridmoment (STT) har fört spinntroniken allt närmare praktiska elektroniska tillämpningar, såsom MRAM och den spinntroniska mikrovågsoscillatorn (STO), och har blivit ett allt mer attraktivt forskningsområde inom spinndynamik. Användning av material med vinkelrät magnetisk anisotropi (PMA) i sådana tillämpningar erbjuder flera stora fördelar, såsom låg strömförbrukning och funktion vid låga fält i kombination med hög termisk stabilitet. Den utbyteskoppling (”exchange bias”) en PMA-tunnfilm utövar på ett intilliggande skikt med magnetisk anisotropi i planet (IMA) kan få IMA-magnetiseringsriktningen att vridas ut ur planet, vilket ger en materialstack med en effektivt sett lutande magnetisk anisotropi. Lutningsvinkeln kan manipuleras med både inre materialparametrar, såsom PMA och mättningsmagnetisering, och yttre parametrar, såsom skikttjocklekarna. STO:er kan tillverkas som flera olika typer - som en nanokontaktsöppning på en s.k. mesa av en deponerad pseudospinnventilstruktur (PSV) eller som en nanotråd etsad ur en magnetisk tunnlingsövergång (MTJ) –och bestå av mycket reproducerbar PMA eller av skikt med på förhand bestämt lutning av dess magnetiska anisotropi. MTJ-STO:er av CoFeB med helt vinkelrät anisotropi visar högfrekvent mikrovågsgenerering med extremt stort frekvensomfång hos strömstyrningen, detta vid låg biasering. Mätning och analys av spinnvridmoments-ferromagnetisk resonans (ST-FMR) avslöjade ett biasberoende hos spinnvridmomentskomponenter, vilket indikerar en stor potential för direkt gate-spänningsstyrda STO:er. I helt vinkelräta PSV-STO:er observerades magnetiska droppar under nanokontaktområdet vid låg drivström och lågt pålagt fält. Dessutom erhölls preliminära resultat av mikrovågssjälvsvängning och av s.k. ”droplet solitons” hos PSV-STO:er med lutande polarisator. Dessa är lovande och skulle vara värda att undersökas i ytterligare studier av STT-driven spinndynamik.

Problemformulering: Är det möjligt att tillgodose såväl personalens som kundernas önskemål kring personalens kläder och samtidigt följa de kriterier som ställs på arbetskläderna?Metod: Uppsatsen bygger på de undersökningar vi kommer att göra på blodcentralerna. Vi kommer att analysera de svar som vi får och se vad som efterfrågas av personalen och ledningen. Kunden som lämnar blod kommer också att få svara på frågor. Kvalitativa metoder användes under arbetet. Kvalitativa metoder användes vid de intervjuer och studiebesök som genomfördes. Intervjuerna genomfördes i grupp på blodgivningscentralerna. Dessa analyserades sedan efteråt.Undersökningarna var uppdelade i två delar, dels frågeformulär som lämnades på blodcentralerna och dels intervjuer som gjordes med både personal och kunder på blodcentralerna.Studiebesök gjordes även på Tvätteriet Alingsås för att se hur sorteringen går till av kläder.Designprocessen började med att titta på dagens klädsel, vad kan man förbättra och vad kan man ta bort. En kravspecifikation gjordes av de svar som kom fram vid undersökningarna. Det finns olika direktiv för klädsel inom vården som man är tvunget att följa. Kritik gavs på de första utkasten av Ulrika Ljung. Efter detta började således den slutgiltiga designprocessen. Teori: En jämförelse mellan valet av olika material. Polyester, Bomull och Bomull/Polyster gjordes. Mönsterkonstruktionen och passformen finns det ingen direkt tidigare forskning på så bygger uppsatsen mycket på hur dagens klädsel ser ut. Även följa den anbudsspecifikation för Västra Götalandsregionen som finns.Designens påverkan på personalen och kunderna är viktig. Det finns forskning som visar på att en uttalad dresscode kan öka identiteten hos ett företag och öka sammanhållningen. Även respekten hos kunder kan öka. Analys: Den dåliga passformen kommer att försöka ändras med hjälp av andra snitt än vad dagens klädsel har. Nya snitt och andra färger kommer förmodligen att öka moderniteten hos plaggen då detta var något som efterfrågades. De krav som finns för kläder inom vården har följts. Det finns inga krav för kjol då kjol inte finns i dagens kollektion. Här har kraven för klänningen tagits tillvara och applicerats på kjolen.Slutdiskussion: Det som är en viktig del i det här projektet är att få en sammanhängande klädsel för personalen. För att få bort sjukhuskänslan som finns på de olika blodcentralerna krävs att de kläder som används idag tas bort. Men det viktiga är att bevara den auktoritet och trygghet som finns i dagens klädsel. Sjukhuskänslan finns idag såklart för att det är samma kläder som man använder på sjukhusen och på blodcentralerna. Detta kommer förhoppningsvis försvinna då de nya kläderna kommer att särskilja sig från nuvarande klädsel. Valet av material blev ren bomull pga. Känslan i materialet. Ett skönt material efterfrågades av personalen och då valdes bomull just pga. det. Under projektets gång har även nya frågor dykt upp. En sådan var om landstingets tvätteri klarar av att sortera ut en liten kollektion med specifika kläder. Vår undersökning visar att så är fallet. Däremot kan kostnaden bli högre vid en liten kollektion.

AbstractNature of work: Exam 15 creditsTitle: Droppen – Product development of workwear.Keywords: product development, working clothes, design processEducation: Textile product development with a focus on business and entrepreneurshipAuthor: Clara Lycke & Daniel NorinAdvisor: Kristina GutfeltExaminer: Stig NilssonExamination: 2010-05-24Objective: To present a proposal for staff at blood donation centers on a single outfit that will differentiate their clothing from the usual hospital clothes.Problem: Is it possible to meet both staff and customers requirements on staff clothing and comply with the criteria set for work clothes?Method: The essay is based on the surveys we will make at the blood donation centers. We will analyze the responses we get and see what is asked of staff and management. The client who gives blood will also have to answer questions. Qualitative methods were used during the work. Qualitative methods were used during interviews and visits carried out. The interviews were conducted in groups at the blood donation centers. These were analyzed afterwards. The examinations were divided into two parts, the questionnaire was submitted to blood donation centers and both were interviewed, both staff and customers at the blood donation centers. A visit to the laundry of Alingsås was made to see how they sorted the work wear. The designprocess began with watching today's workwear, what you can improve and what can be removed. A requirement specification was made of the response revealed by investigations. There are various directives to trim health care as it is forced to follow. Criticism was the first drafts of Ulrika Ljungberg. After this the final design process began.Theory: A comparison between the choice of materials. Polyester, Cotton and Cotton / polyester was made. There is no previous research of pattern design and fitting, this paper is based on how much today's workwear looks like. Also to follow the tender specification for the Västra Götaland was very important. The design of the work wear impacts on staff and customers is important. There is research that indicates that an explicit dress code may increase the identity of a firm and cohesive. Although the respect of customers may increase.Analysis: We will try to change the bad fit using a different cut than today's clothing has. New cuts and color is likely to increase the modernity of clothes as this was something that was requested. The requirements for clothes in health care have been followed. There are no requirements for skirt because skirts don’t excist in today's collection. Here was the requirements for the dress to be taken and applied to the skirt.Final Discussion: An important part of this project is to obtain a coherent clothing for the staff. To remove the feeling of hospital work wear in the different blood establishments that they are required to wear today, is removed. But the important thing is to preserve the authority and security of today's clothing. The feeling of hospitals is of course because it's the same clothes that they use in hospitals and at blood donation centers. This will hopefully disappear when the new clothes will distinguish itself from existing clothing. The choice of materials was pure cotton because of the feeling in the material. A nice material was requested by the staff and we decided to go with cotton. During the project, new issues have arisen. Such was the County Council's laundry manage to sort out a small collection of specific garments. Our study shows that it is. However, the cost will be higher with a small collection.

In the last decade, the topic of automated surveillance has become very important in the computer vision community. Especially important is the protection of critical transportation places and infrastructure like airport and railway stations. As a step in that direction, we consider the problem of detecting abandoned objects in a crowded scene. Assuming that the scene is being captured through a mid-field static camera, our approach consists of segmenting the foreground from the background and then using a change analyzer to detect any objects which meet certain criteria. In this thesis, we describe a background model and a method of bootstrapping that model in the presence of foreign objects in the foreground. We then use a Markov Random Field formulation to segment the foreground in image frames sampled periodically from the video camera. We use a change analyzer to detect foreground blobs that remain static through the scene and based on certain rules decide if the blob could be a potentially abandoned object.

Abstract:
Dropped objects are among the top ten causes of fatalities and serious injuries in the oil and gas industry. Objects may be dropped during lifting or any other offshore operation. Concerns of health, safety, and the environment (HSE) as well as possible damages to structures require the prediction of where and how a dropped object moves underwater. This study of dropped objects is subdivided into three parts. In the first part, the experimental and simulated results published by Aanesland (1987) have been successfully reproduced and validated based on a two-dimensional (2D) theory for a dropped drilling pipe model. A new three-dimensional (3D) theory is proposed to consider the effect of axial rotation on dropped cylindrical objects. The 3D method is based on a modified slender body theory for maneuvering. A numerical tool called Dropped Objects Simulator (DROBS) has been developed based on this 3D theory. Firstly, simulated results of a dropped drilling pipe model using a 2D theory by Aanesland (1987) are compared with results from 3D theory when rolling frequency is zero. Good agreement is found. Further, factors that affect the trajectory, such as drop angle, normal drag coefficient, binormal drag coefficient, and rolling frequency are systematically investigated. It is found that drop angle, normal drag coefficient, and rolling frequency are the three most critical factors determining the trajectories. In the second part, a more general three-dimensional (3D) theory is proposed to physically simulate the dynamic motion of a dropped cylindrical object underwater with different longitudinal center of gravity (LCG). DROBS has been further developed based on this 3D theory. It is initially applied to a dropped cylinder with LCG = 0 (cylinder #1) falling from the surface of calm water. The calculated trajectories match very well with both the experimental and numerical results published in Aanesland (1987). Then DROBS is further utilized to simulate two dropped cylinders with positive LCG (cylinder #2) and negative LCG (cylinder #3) in Chu et al. (2005), respectively. The simulated results from DROBS show a better agreement with the measured data than the numerical results given in Chu et al. (2005). This comparison again validates and indicates the effectiveness of the DROBS program. Finally, it’s applied to investigate the effects of varying LCG on the trajectory and landing points. Therefore, the newly developed DROBS program could be used to simulate the distribution of landing points of dropped cylindrical objects, as is very valuable in the risk-free zone prediction in offshore engineering. The third part investigates the dynamic motion of a dropped cylindrical object under current. A numerical procedure is developed and integrated into Dropped Objects Simulator (DROBS). DROBS is utilized to simulate the trajectories of a cylinder when dropped into currents from different directions (incoming angle at 0o; 90o; 180o; and 270o) and with different amplitudes (0m/s to 1.0m/s). It is found that trajectories and landing points of dropped cylinders are greatly influenced by currents. Cylinders falling into water are modeled as a stochastic process. Therefore, the related parameters, including the orientation angle, translational velocity and rotational velocity of the cylindrical object after fully entering the water, is assumed to follow normal distributions. DROBS is further used to derive the landing point distribution of a cylinder. The results are compared to Awotahegn (2015) based on Monte Carlo simulations. Then the Monte Carlo simulations are used for predicting the landing point distribution of dropped cylinders with drop angles from 0o to 90o under the influence of currents. The plots of overall landing point distribution and impact energy distribution on the sea bed provide a simple way to indicate the risk-free zones for offshore operation.

Abstract:
Flippfloppsandaler förknippas med sol och ledighet i Sverige. Men i många andra länder är det en sko som används dagligen, året om. Det sägs vara världens mest sålda sko. Den är billig och åker lätt på foten men den åker lika snabbt av. Vid kraftigt regn riskerar avställda floppfloppsandaler att flyta iväg från sina ägare. De åker längs vattendrag och inte sällan ut i havet tillsammans med en massa annat skräp. För personen som blev av med sandalerna kanske det inte gör så mycket, det går ju att köpa ett par nya i närmsta kiosk. Men faktum är att de är en del av ett stort problem. Plaster i haven bryts inte ner biologiskt utan blir mindre och mindre bitar av solen. Plastbitarna äts av fiskar och fåglar som tar skada. Plast drar också till sig gifter som PCB och DDT. När människor äter fisk som fått i sig plast vandrar gifterna uppåt i näringskedjan. Efter att länge färdats på havet kanske flippfloppsandalen spolas upp på land. Och kanske hittas den då av företaget och organisationen Ocean Sole i Kenya. De plockar tappade flippfloppsandaler i slumområden och längs Kenyas kust. Vissa sandaler har flutit dit ända från Asien. Flippfloppsandalerna sorteras, tvättas, limmas ihop, skärs till och slipas av hantverkare i Nairobi därefter. De blir till allt från skulpturer till smycken som säljs världen över. Ocean Sole återvinner ett ton flippfloppsandaler i veckan och det ser inte ut som att de någonsin kommer få slut på material. Flippfloppsandalen är i sig en symbol för slit- och slängsamhället men bär också ett meddelande från havet om att havet håller på att bli världens soptipp. Radioreportaget belyser därmed ett stort problem genom en enskild produkts livscykel.

Abstract:
Behörighetsutredning tillsattes år 2009 för att ta reda på huruvida legitimerade svenska op-tiker med kontaktlinsbehörighet bör få använda diagnostika eller ej. Ett godkännande skulle innebära utökade arbetsuppgifter och större ansvar. Syftet med denna studie var att ta reda på hur svenska optiker ställer sig till en eventuell lagändring där diagnostika godkänns som hjälpmedel i det kliniska arbetet. Även viljan att vidareutbildas för att få behörigheten utreds. Enkäter i pappersform skickades ut till optiker i Sveriges alla 21 län. Det som tillfrågades var bland annat inställning till diagnostiska droppar som hjälpmedel, inställning till vidare-utbildning, kön, ålder, kedjetillhörighet, antal år i branschen samt antal år som kontaktlins-behörig. 53 personer deltog i undersökningen, varav 30 kvinnor och 23 män. 64 % av alla frågade ställer sig positivt till förslaget. Män visar sig vara mer positiva än kvinnor. Vad gäller vil-jan att vidareutbildas valde de allra flesta alternativet "inte nu" då frågan ställdes. De allra flesta legitimerade optiker med kontaktlinsbehörighet är positivt inställda till an-vändande av diagnostiska droppar. I framtiden bör man utreda hur inställningen är då dia-gnostiska droppar får användas.

Abstract:
Developments in marine aquaculture in the last 30 years indicate that the bivalve-related industry is feasible offshore and that opportunities for large-scale, industrious production of shellfish stock exists. The objective of the project “CAWX1607” is to develop, model and test such systems. However, the forces acting on suspension cultures, the most likely form of marine farm systems are unknown. Here, drag coefficients provide an efficient approach for the calculation of arbitrary complex structures by using the Morison equation. The CD-coefficients take into account vortex shedding effects as well as the surface roughness of the structure. This paper reports on developed and conducted tests at the medium wave and towing tank “Schneiderberg” (WKS) at the Ludwig-Franzius-Institute for Hydraulic, Estuarine and Coastal Engineering of the Leibniz University Hanover, Germany. The tests were conducted for current velocities between 0.25–1.0 m/s for three samples of blue-lipped mussel specimens. During physical testing the forces and moments in x-, y- and z-direction, the elevation of the water surface, a velocity profile in the vicinity of the live-blue mussels, as well as the velocities of the towing carriage were recorded. The developed methodology, data treatment as well as the resulting CD-coefficients are presented. Further, the CD-coefficients obtained are presented in the context of natural variation of living structures and discussed in comparison to CD—curve characteristics of offshore structures, e.g. rough cylinders.
