Full textAbstract:
<p>Unmanned Aerial Vehicles (UAVs) have a tremendous appeal. One can imagine a large number of applications such as search-and-rescue, traffic monitoring, aerial mapping, etc. Helicopters are particularly attractive due to their Vertical Take Off and Landing (VTOL) capabilities. The research on UAVs has shown rapid development in recent years, and offers a great number of challenges. This thesis is the result of a project which is a part of the Autonomous Remote Controlled Helicopter (ARCH) project at the Department of Computer and Information Science, Norwegian University of Science and Technology. The ARCH project has already gained public interest, when it was featured on a television program (Schrödingers katt, NRK. September 2004). The object of this thesis is divided into three main sections. Firstly, it is to create and describe a remote control system for controlling the UAV in semi-autonomous mode, that will also enable the UAV to autonomously follow objects (pursuit-mode). Secondly, it is to create and describe a virtual cockpit which is to be used with the remote control system. Finally, it is to create and describe an image stabilization system, which can stabilize the visual information sent from the UAV to the ground and the virtual cockpit. These three components have been combined and integrated into the client prototype called ARCH Groundstation. Together, these three components provides a platform for an operator to control the ARCH UAV in semi-autonomous mode.</p>

This project seeks to design and construct a track-driven radio controlled vehicle and controller. The purpose is to research if radio can be effectively used to control the robot remotely, as well as research to what extent a tracked design increases the mobility when compared to a wheel-design. The prototype consists of two parts: Vehicle and controller. The vehicle is track-driven with two DC-engines connected by H-bridge. A receiver is fitted to the vehicle. The controller consists of two joysticks, a linear potentiometer as well as a transmitter. Testing was performed by driving the vehicle on different terrain.The results show that it is possible to control via RC and that the vehicle had increased mobility compared to wheeled designs. Two problems were identified: Firstly, the tracks used lacks friction, causing the vehicle to glide when attempting to climb certain objects. Secondly, due to the design of the chassis, objects contact the chassis body instead of the tracks. Causing the vehicle to stall.<br>Detta projekt menar att designa samt konstruera ett banddrivet radiostyrt fordon och tillhörande kontroll. Syftet med detta är att forska om radiostyrning kan effektivt användas för fjärrstyrning och för att undersöka om band-drift ökar fordonets rörlighet jämfört med hjuldrivna motsvarigheter. Prototypen består av två delar; fordon och kontroll. Fordonet är band-drivet med två DC-motorer med högt drivmoment kopplade till en H-brygga. En mottagare är monterad på fordonet. Kontrollen består av två joysticks, en linjärpotentiometer samt en sändare. Testen genomfördes genom att låta fordonet köra över olika terräng. Resultaten av testerna visade att det är möjligt att fjärrstyra med RC samt att fordonet hade ökad rörlighet jämfört med hjuldrivna motsvarigheter. Två problem identifierades under testen. Banden saknar friktion och glider ibland i stället för att klättra över hinder. På grund av chassits form kolliderade ibland objekt med chassit före banden vilket stoppade fordonet.

Full textAbstract:
There is significant interest in the development of hydrogels and hydrogel nanocomposites for a variety of biomedical applications including drug delivery, sensors and actuators, and hyperthermia cancer treatment. The incorporation of nanoparticulates into a hydrogel matrix can result in unique material characteristics such as enhanced mechanical properties, swelling response, and capability of remote controlled (RC) actuation. In this dissertation, the development of hydrogel nanocomposites containing magnetic nanoparticles/carbon nanotubes, actuation with remote stimulus, and some of their applications are highlighted.
The primary hydrogel nanocomposite systems were synthesized by incorporation of magnetic nanoparticles into temperature responsive N-isopropylacrylamide (NIPAAm) matrices. Various nanocomposite properties were characterized such as temperature responsive swelling, RC heating with a 300 kHz alternating magnetic field (AMF), and resultant collapse. The nanoparticle loadings and hydrogel composition were tailored to obtain a nanocomposite system that exhibited significant change in its volume when exposed to AMF. The nanocomposites were loaded with model drugs of varying molecular weights, and RC pulsatile release was demonstrated.
A microfluidic device was fabricated using the low temperature co-fired ceramic (LTCC) processing technique. A magnetic nanocomposite of PNIPAAm was placed as a valve in one of the channels. The remote controlled liquid flow with AMF was observed for multiple on-off cycles, and the kinetics of the RC valve were quantified by pressure measurements.
The addition of multi-walled carbon nanotubes (MWCNTs) in NIPAAm matrices was also explored for the possibility of enhancement in mechanical properties and achieving remote heating capabilities. The application of a radiofrequency (RF) field of 13.56 MHz resulted in the remote heating of the nanocomposites. The intensity of the resultant heating was dependent on the MWCNT loadings.
In order to further understand the RC actuation phenomenon, a semi-empirical heat transfer model was developed for heating of a nanocomposite disc in air. The model successfully predicted the temperature rise as well as equilibrium temperatures for different hydrogel dimensions, swelling properties, nanoparticles loadings, and AMF amplitude. COMSOL was used to simulate temperature rise of the hydrogel nanocomposite and the surrounding tissue for hyperthermia cancer treatment application.

radio frequency between the Orbitor on-board computer and a remote computer.
The second objective was to establish a software system for the overall control of
the Orbitor AGV system. This objective involved creating software for the
on-board computer and the remote computer. Software communication protocols
were implemented and tested between the remote computer and the Automatic

Thesis, KTH, Hållbar utveckling, miljövetenskap och teknik, 2019. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-256332.
Full textAbstract:
Water is an essential resource for basic human survival, but today several cities and people lack access to both reliable and clean water. Dar es Salaam in Tanzania is undergoing a rapid population growth and need to improve their current water delivery system in order to provide water to the city’s inhabitants. This report’s objective is to examine if Dar es Salaam Water and Sewerage Authority (DAWASA) manual water valve operation is improved with the usage of remote-controlled valves instead. The remote-controlled system will consequently be evaluated and compared against the manually controlled valves. In order to obtain necessary data for this study interviews and field trips were conducted at DAWASA as well as at the local market at Kariakoo. Additionally, information has also been gathered from the collaboration partners at College of Information and Communication Technologies (CoICT). The results provided information that a remote-controlled system could, in the measured reference area of 52 km of water pipes, save up to 900 U.S dollar monthly and 46 m3 of water daily for DAWASA. These savings would consequently contribute to an increase in resources which leads to further improvements to the current water distribution system. Because, today’s system is in need of a development in order to sufficiently provide potable water to the city. The remote-controlled system could also help to reduce the spread of waterborne diseases, destruction of roads and create a more reliable source of water since the water valves would be regulated more efficiently. A remote-controlled system would however need a sufficient amount of funding in order to be installed, but is both simpler to install and a more feasible solution compared to other alternatives. For these reasons, the designed system is concluded to be a more effective, sustainable and economical feasible solution for handling and managing the outdated valves.

Non-controlled airports are literally that - uncontrolled. Safe separation is achieved by pilot vigilance. The consensus of reports on incidences at noncontrolled airports generally conclude that pilots cannot rely entirely on vision to avoid collision and attempts should be made to obtain all available traffic information to enable a directed traffic search. Ideally, a system is required which has the ability to provide advice to all parties to ensure separation minima is maintained. Provision of a such a system would remove a measure of pressure from the pilot to allow that person to devote their attention to their prime responsibility of flying the aircraft. To this end, research on use of intelligent remote advisory systems for non-controlled airports was undertaken with emphasis on those systems which could minimize human resources and associated recurring costs, to provide a measure of repeatability and to provide an acceptable level of safety. A rule based system was developed and evaluated. The evaluation showed that use of a rule based system as the basis of an intelligent remote air traffic control system for non-controlled airports is a viable proposition. In test scenarios, collision hazards were identified and evasion tactics generated. For a full operational system, the application of the rules and definition of the aircraft circuit area may need refining; however, the results are certainly encouraging.

Full textAbstract:
Remote controlled switches (RCS) are used to enhance the recovering process of distribution grids. Commonly installed on MV-lines to sectionize feeders, they are a cheap and efficient way to improve the B criterion as well as the incident localisation speed. This document explains and models the impact of Remote controlled equipment on B criterion and reactivity depending on grid structure and organisation (II and III). This model is then used to define an optimal remote controlled switcher number per feeder on each specific area (V). It leads to two main results: French territory is not homogeneously equipped and a lot of areas need a strong RCS policy. RCS efficiency on distributor performance is also proved to be high even for well-equipped areas.

One of the most powerful capabilities of nature is specific catalysis of chemical reactions by enzymes, i.e., sequence-defined biopolymers with defined three-dimensional geometry, in living organisms. The aim of introducing conformational changes with potentially similar capabilities into synthetic polymers led to the development of so-called single-chain nanoparticles (SCNP). The current thesis focuses on generating remotely and reversible foldable SCNPs using photochemistry. The development of a platform technique, paired with deep understanding of the folding process, is critical for mimicking biocatalysis.

Computer games may be defined as artifacts that connect the input devices of a computer (such as keyboard, mouse or controller) with its output devices (in most cases a screen and speakers) in such a way that on the screen a challenge is displayed. On the screen we see pictorial elements that have to be manipulated to master a game, that is to win a competition, to solve a riddle or to adopt a skill. Therefore the characteristics of the representational function of computer games have to be contrasted phenomenologically with conventional games on the one hand and cinematic depictions on the other. It shows that computer games separate the player from the playing field, and translate bodily felt concrete actions into situational abstract cinematic depictions. These features add up to the situational abstract presentation of self-action experience. In this framework computer games reveal a potential as a new means of shared cognition that might unfold in the 21st century and change the beingin- the-world in a similar way as cinematic depiction did in the 20th century

Full textAbstract:
The Distribution Network Operators (DNOs) have to ensure that electricity is supplied to customers according to voltage quality and power reliability requirements. The SAIDI (System Average Interruption Duration Index) is a performance index commonly used to measure reliability which expresses the average outage duration for each customer served. When an outage occurs on the distribution grid, remote controlled sectionalizers (RCS) are operated to enhance the restoration of power by sectionalizing the medium voltage (MV) grid before repairing the line. By analyzing data of outages, considering the frequency, the duration and the size of outages, statistical methods can be outlined to identify MV-lines where RCS investments may have significant improvements on reliability. To assess reliability improvements, RCS investment costs are compared to failure costs by setting an outage price through the cost of energy not served (ENS).

Full textAbstract:
When lifting unbalanced objects with a crane or other lifting equipment it can be hard to getthe object leveled. This is dealt with in ways which often rely on experienced workers and can bedangerous as well as time consuming. A remote leveling lifting yoke (LLY) can be a solution to thisproblem, there are currently only one such product available capable of lifting up to 20 tonnes calledL20. The L20 is however rather large and not practical for smaller lifts or lifting equipment. Thisreport investigates weather a smaller version of L20 is needed and how it should function. By usingmodern product development techniques a few concepts to a new LLY was presented. The conceptsare based on the fundamental working principles of the existing L20, that is being battery poweredand leveling the load by a chain with its two ends connected to the lifted object driven by a chainwheel. The main challenge during the concept development was to gure out a brake function whichwould prevent the driving mechanism from being overloaded in the event of an unexpected load shift.Another challenge was to try to implement a freewheel function which would enable the chain wheelto spin freely making it possible to adjust the chains by hand. From the prestudy it was seen thatin order to make this new LLY unique, the remote controlled function would be the main thingsetting it apart from alternatives on the market. The freewheel ability was also not seen amongst thecompetitor products.The most promising concept turned out to be a worm gear drive system since they are inherentlyself locking thus solving the brake problem as well as eliminating the need for much of the gearreduction. However no easy way of adding a freewheel ability with this system was found but this isintended to be worked around by adding a high speed gear used when fast changes need to be made.

Full textAbstract:
<p>This report considers the work to improve the autonomy of surgical teleoperated systems, by introducing haptic guidance. The use of surgical robots in surgical procedures have become more common the recent years, but still it is in its infancy. Some advantages when using robots is scalability of movements, reduced tremor, better visualisation systems and greater range of motions than with conventional minimally invasive surgery. On the contrary, lack of tactile feedback and highly unstructured medical environment restricts the use of teleoperated robots to specific tasks within specific procedures. A way of improving autonomy of the teleoperated system is to introduce predefined constraints in the surgical environment, to create a trajectory or forbidden area, in order to guide the movements of the surgeon. This is often called haptic guidance. This report introduces the basics of teleoperated systems, with control schemes, models and analytical tools. Algorithms for haptic guidance have been developed, and the entire control and guidance system have been modified and suited for implementation on a real teleoperated system. Theoretical analysis of the position position (PP) control scheme reveals some general stability and performance characteristics, later used as a basis for tuning the real system parameters. The teleoperated system consists of a Phantom Omni device, from SensAble-Technologies, used as master manipulator, and AESOP 3000DS, from Computer Motions Inc., as the slave manipulator. The control system is implemented on a regular PC, connecting the complete system. Tests reveal that the slave manipulator is not suited for this task due to a significant communication time delay, limited velocity and inadequate control possibilities. The consequences makes force feedback based on the PP control scheme impossible, and limits performance of the entire teleoperated system. The guidance system is implemented in two variations, one based on slave positions and one based on master positions. This is motivated to give a performance comparison for variations of position error/tracking between the two manipulators. Slave based guidance appears to be stable only for limited values of the gains, and thus, it generates no strict constraints. It can be used to guide the operator away from forbidden areas, but is not suitable for high precision guiding. The master based guidance is stabile for very high gains, and the guidance have the accuracy to improve the surgeons precision during procedures. In the case of line guidance, the master based guidance gives a deviation of up to $1.3mm$ from the given trajectory. The work has shown the possibilities of using haptic guidance to improve accuracy and precision in surgical procedures, but among others, hardware limitations give room for several improvements in order to develop a teleoperated system that works.</p>

Full textAbstract:
Walking robots are useful in search and rescue applications due to their ability to navigate uneven and complex terrain. A hexapod robot has been developed by the Robotics and Agents Research Lab at UCT, however multiple inadequacies have become evident. This work aims to produce a mathematical model of the hexapod and using this model, implement an effective control algorithm to achieve a smooth walking motion and overcome the original flaws. The mathematical model was integrated with the mechanical structure of the hexapod and controlled by a micro-controller. This micro-controller allows for a rapid start-up and low power consumption when compared to previous iterations of the hexapod. Using a path generation algorithm sets of foot positions and velocities are generated. Generating these points in real time allows for walking in any direction without any pre-defined foot positions. To enable attitude control of the hexapod body, an inertial measurement unit was added to the hexapod. By using a PID controller the IMU pitch and roll data was used to control a height offset of each foot of the hexapod, allowing for stabilisation of the hexapod body. An improved wireless remote control was developed to facilitate communication with a host computer. The remote system has a graphical user interface allowing for walking control and status information feedback, such as error information and current battery voltage. Walking tests have shown that the hexapod walks successfully with a smooth tripod gait using the path generation algorithm. Stabilisation tests have shown that the hexapod is capable of stabilising itself after a disturbance to its pitch and/or roll in ±2.5 seconds with a steady state error of ±0.001 radians. This proves that the hexapod robot can be controlled wirelessly while walking in any direction with a stabilised body. This is beneficial in search and rescue as the hexapod has a high degree of manoeuvrability to access areas too dangerous for rescuers to access. With cameras mounted on the stabilised body, it can be used to locate survivors in a disaster area and assist rescuers in recovering them with speed.

Full textAbstract:
Photochrome Diarylethene haben die einzigartige Eigenschaft, dass ihr pi-Elektronensystem durch den Isomerisierungsprozess stark verändert wird, was zu einer Verschiebung von HOMO und LUMO Niveaus führt. Zur Verwendung von Diarylethenen zur Steuerung von Funktionen, wie katalytische Aktivität, supramolekulare Assoziation oder Ladungstransport, muss die photochrome Baueinheit den spezifischen Anforderungen angepasst und ihre Schalteigenschaften, die Ermüdungsresistenz sowie das Ausmaß der elektronischen Modulation verbessert werden. In dieser Arbeit wird durch systematische Variation der zentralen Komponenten und der terminalen Substituenten eine Serie von elektronisch modulierten Diarylethenen synthetisiert. Durch umfangreiche Untersuchungen zur photochemischen Bildung eines Nebenprodukts, ein Prozess der bei nahezu allen Diarylethenen auftritt, können Strukturen identifiziert werden, die über eine große Zahl von Schaltzyklen ermüdungsresistent sind und gleichzeitig eine hohe strukturelle und synthetische Flexibilität bieten. Weiterhin erlauben bestimmte Substitutions-muster die orthogonale elektro- und photochemische Steuerung des Isomerisierungsprozesses. Durch geeignete strukturelle Modulation wird die Nebenproduktbildung bei der oxidativen Zyklisierungsreaktion unterdrückt und es kann ein Einblick in den zugrunde liegenden Mechanismus erhalten werden. Der Einfluss verschiedener Substitutionsmuster auf das pi Elektronensystem von Diarylethenen wird untersucht und es wird gezeigt, dass HOMO und LUMO Level über einen großen Energiebereich moduliert werden können. Die so erhaltenen elektronisch modulierten Diarylethene werden als aktive Elemente in Licht gesteuerten organischen Dünnschichttransistoren eingesetzt. In einem weiteren Ansatz die schaltbaren elektronischen Änderungen in Diarylethenen zu nutzen, wird ein potentiell katalytisch aktives Guanidin mit der photochromen Einheit gekoppelt, mit dem Ziel einen photoschaltbaren Organokatalysator zu konstruieren.<br>Photochromic diarylethenes have the unique property that the pi-electronic structure of their molecular backbone significantly alters during the isomerization process, resulting in a marked shift of HOMO and LUMO levels. In order to employ diarylethenes for the reversible light-controlled manipulation of specific functions, such as catalytic activity, association behavior, or charge transport, the photochromic scaffold has to be improved in terms of its switching efficiency, fatigue resistance, and extent of electronic modulation. In this work, a series of diarylethenes is synthesized by systematically varying the constituents of the hexatriene core and the terminal substituents. By the in-depth characterization of the photochemical reaction to a by-product, an ubiquitous phenomenon of diarylethene photochromism, fatigue resistant structures are identified that allow for the reliable operation of the photochrome over many switching cycles and at the same time guarantee a high degree of structural and synthetic flexibility. Furthermore, a distinct substitution pattern is found to enable the orthogonal electro- and photochemically mediated isomerization of diarylethenes. By proper modulation of the structure, the fatigue observed during the oxidative cyclization reaction is minimized and insights into the underlying mechanism are gained. The impact of different substitution patterns on the pi-electronic structure of the diarylethene core is studied and it is shown that HOMO and LUMO levels can be tuned over a broad energy range. The electronically tuned diarylethenes are applied as active building blocks in light-controllable organic thin film transistors. In a second approach to exploit the isomerization induced electronic modulations, a potentially catalytically active guanidine unit is coupled to the diarylethene core in order to construct a photoswitchable organocatalyst.

Full textAbstract:
A 4-year old child with autism was taught to make a social initiation statement following a remote-controlled tactile prompt (RCT). The RCT prompt was taught by using a time-delay procedure with written script cards containing initiation statements. Training trials occurred in 6 different play locations in the child's room. Restricted Trial training consisted of allowing the child to play independently, activating the RCT prompt and playing with the child based on any initiation until a warning to end was
given. In Free Play training, the warning to end the activity was removed. The child's initiation statements
increased from 0 in baseline, to spontaneous initiations in 100% of the trials in all training and generalization phases. The number of words in an initiation statement increased from 3 to 25 per trial. Spontaneous initiations in the No RCT phase generalized to the child's mother without training.

This thesis describes the process of designing the central unit to the SafeTool system. The main tasks for the central unit are to act as a communication hub, to control external devices and to collect data. The unit is based on AVR microcontrollers and the design process consists of different communication interfaces, output and input control and power management. In addition to this the process of choosing appropriate RFID technology is also described. The design process has resulted in a fully operable SafeTool system that will reach the market in the third quarter of 2005.

Full textAbstract:
This thesis relates to the development of the Ambidextrous Robot Hand engineered in Brunel University. Assigned to a robotic hand, the ambidextrous feature means that two different behaviours are accessible from a single robot hand, because of its fingers architecture which permits them to bend in both ways. On one hand, the robotic device can therefore behave as a right hand whereas, on another hand, it can behave as a left hand. The main contribution of this project is its ambidextrous feature, totally unique in robotics area. Moreover, the Ambidextrous Robot Hand is actuated by pneumatic artificial muscles (PAMs), which are not commonly used to drive robot hands. The type of the actuators consequently adds more originality to the project. The primary challenge is to reach an ambidextrous behaviour using PAMs designed to actuate non-ambidextrous robot hands. Thus, a feasibility study is carried out for this purpose. Investigating a number of mechanical possibilities, an ambidextrous design is reached with features almost identical for its right and left sides. A testbench is thereafter designed to investigate this possibility even further to design ambidextrous fingers using 3D printing and an asymmetrical tendons routing engineered to reduce the number of actuators. The Ambidextrous Robot Hand is connected to a remote control interface accessible from its website, which provides video streaming as feedback, to be eventually used as an online rehabilitation device. The secondary main challenge is to implement control algorithms on a robot hand with a range twice larger than others, with an asymmetrical tendons routing and actuated by nonlinear actuators. A number of control algorithms are therefore investigated to interact with the angular displacement of the fingers and the grasping abilities of the hand. Several solutions are found out, notably the implementations of a phasing plane switch control and a sliding-mode control, both specific to the architecture of the Ambidextrous Robot Hand. The implementation of these two algorithms on a robotic hand actuated by PAMs is almost as innovative as the ambidextrous design of the mechanical structure itself.

Before vehicles that go to sale for public it goes through many stages of testing in different fields. All types of pre-production cars are the vehicles that come after prototypes which allow the OEM to find out possible issues by running different categories of tests. One of the most important fields of test is regarding safety. When it comes to autonomous cars, where safety is crucial, the number of tests to carry out, time for handling them and their complexity is increased. To reduce costs, complexity and time some of them might be simulated. After the analysis is done the cars have to be tested in real time to collect more data, not only from car sensors but also through observation from the tests filmed. This thesis contains an overview of whole project leading to develop an autonomous platform, driving after autonomous car and controlled by simulation environment and solving major issues of the project. The filming of autonomous cars remotely had two major issues. One of the issues was to integrate all the different software and platforms. The trajectories of the autonomous cars were controlled in different software and the trajectories of the RC were managed in different software. The solution to integrate all the software and platforms is shown in this thesis. The second issue was to make the RC car to follow the waypoints that are generated by simulation and by communicating with real car using a PID controller. The project is prepared for future improvements, like installing a camera to the RC car which will follow predefined test independently.

We present a concept and implementation on increasing the efficiency of webinar software by a remote control approach using the technology WebRTC. This technology enables strong security and privacy, is crossdevice usable, uses open-source technology and enables a new level of interactiveness to webinars. We used SlideWiki, WebRTC, and browser speech to text engines to provide innovative accessibility features like multilingual presentations and live subtitles. Our solution was rated for real world usage aspects, tested within the SlideWiki project and we determined technological limits. Such measurements are currently not available and show that our approach outperforms open-source market competitors by efficiency and costs.

Full textAbstract:
Question: Do people with musculoskeletal conditions better adhere to their home exercise programs (HEPs) when these are provided to them on an app with remote support compared to paper handouts? Design: Randomised, parallel-group trial with intention-to-treat analysis. Participants: Eighty participants with upper or lower limb musculoskeletal conditions who were prescribed a 4-week HEP by a physiotherapist at a tertiary teaching hospital in Australia were recruited to the trial. Participants were randomly assigned via a computer-generated concealed block randomisation procedure to either intervention (n = 40) or control (n = 40) groups between 25/02/16 and 13/01/17. Intervention: Participants in the intervention group received their HEPs on an app linked to www.physiotherapyexercises.com. They also received supplementary phone calls and motivational text messages. Participants in the control group received their HEPs as a paper handout. Outcome measures: Outcome measures were collected at baseline and at 4 weeks by blinded assessors. The primary outcome was self-reported exercise adherence. Secondary outcomes included measures of function, disability, satisfaction with service delivery and assessor-reported adherence. Results: Outcomes were available on 77 participants. Three were lost to follow up. The mean between-group difference for self-reported exercise adherence at 4-weeks was 1.3/11 points (95% CI, 0.2 to 2.3), favouring the intervention group. The mean between-group difference for the patient-specific functional scale was 0.9/11 points (95% CI, 0.1 to 1.7) in favour of the intervention group. There were no significant between-group differences for the remaining outcomes. Conclusion: Patients with musculoskeletal conditions better adhere to their HEPs when these are provided to them on an app with remote support compared to paper handouts, however, the clinical importance of this added adherence is unclear.

Full textAbstract:
Hydrogels are popular materials for biological applications since they exhibit properties like that of natural soft tissue and have tunable properties. Biodegradable hydrogels provide an added advantage in that they degrade in an aqueous environment thereby avoiding the need for removal after the useful lifetime. In this work, we investigated poly(β-amino ester) (PBAE) biodegradable hydrogel systems. To begin, the factors affecting the macromer synthesis procedure were studied to optimize the reproducibility of the resulting hydrogels made and create new methods of tuning the properties. Hydrogel behavior was then tuned by altering the hydrophilic/hydrophobic balance of the chemicals used in the synthesis to develop systems with linear and two-phase degradation profiles. The goal of the research was to better understand methods of controlling hydrogel properties to develop systems for several biomedical applications.
Several systems with a range of properties were synthesized, and their in vitro behavior was characterized (degradation, mechanical properties, cellular response, etc.). From these studies, materials were chosen to serve as porogen materials and an outer matrix material to create a composite scaffold for tissue engineering. In most cases, a porous three dimensional scaffold is ideal for cellular growth and infiltration. In this work, a composite with a slow degrading outer matrix PBAE with fast degrading PBAE microparticles was created. First, a procedure for developing porogen particles of controlled size from a fast-degrading hydrogel material was developed. Porogen particles were then entrapped in the outer hydrogel matrix during polymerization. The resulting composite systems were degraded and the viability of these systems as tissue engineering scaffolds was studied.
In a second area of work, two polymer systems, one PBAE hydrogel and one sol-gel material were altered through the addition of iron oxide nanoparticles to create materials with remote controlled properties. Iron oxide nanoparticles have the ability to heat in an alternating magnetic field due to the relaxation processes. The incorporation of these nanoscale heating sources into thermosensitive polymer systems allowed remote actuation of the physical properties. These materials would be ideal for use in applications where the system can be changed externally such as in remote controlled drug delivery.

This report explores the design of a system for remotely switching electronics on and off within a range of at least 15 km, to be used with battery driven radio nodes for outdoor Wi-Fi network bridging. The application of the network bridges are connecting to remote networks, should Internet infrastructure fail during an emergency.The problem statement for the report was “What is a suitable radio link technology for use in a remote controlled electrical switch system and how should it best be put to use?” To answer the question, delimitation was done to exploring Low Power Wide Area Network (LPWAN) link technologies, due to their prior use within power constrained devices.Long Range-radio, abbreviated LoRa, is a LPWAN radio modulation technique and was determined to be a good candidate as a suitable link technology for the remote electrical switch system. The range of LoRa is achieved by drastically lowering the data rate of the transmission, and is suitable for battery-powered or energy harvesting devices such as those found in the field of Internet of Things.A LoRa-based transmitter and receiver pair was implemented, and measured to have a packet delivery ratio of over 95% at a distance of 2 km, measured between two bridges. Data at further distances could not be accurately determined, because of the LoRa transceiver giving faulty readings.No conclusion could be made about the suitability for using a LoRa based system to solve the problem, partially due to an improper method for testing the radio performance was used, and partially due to an inconclusive measurement result.<br>Denna rapport utforskar designen av ett system för att fjärrstyrt slå på eller av elektronik över ett avstånd på minst 15 km, för att användas med batteridrivna radionoder för nätverksbryggning utomhus med Wi-Fi. Tillämpningsområdet för nätverksbryggorna är att koppla samman avlägsna nätverk, om Internetinfrastruktur skulle sluta fungera vid en nödsituation.Problemställningen för rapporten var ”Vad är en lämplig radiolänksteknik att använda i ett fjärrstyrt elektriskt strömbrytarsystem, och hur ska det bäst brukas?”. För att svara på frågan gjordes en avgränsning att utforska Low Power Wide Area Network (LPWAN)-länktekniker, på grund av deras tidigare användning inom effektbegränsade enheter.Long Range-radio, förkortat LoRa, är en radiomodulationsteknik som används för att skicka data över långa avstånd med energibegränsade enheter. LoRa:s räckvidd uppnås genom att drastiskt sänka datatakten, och lämpar sig för bruk i batteridrivna eller energiskördande enheter, likt de som återfinns inom fältet Internet of Things.Ett LoRa-baserat sändaroch mottagarpar implementerades, och uppmättes till att ha en paketlevereringsmängd på över 95% vid ett avstånd på 2 km, mätt mellan två broar. Data vid större avstånd kunde inte bli bestämt noggrant, eftersom LoRa transceivern gav felaktiga avläsningar. Ingen slutsats kunde göras för lämpligheten för att använda ett LoRa-baserat system för att lösa problemet, delvist för att en olämplig metod för att testa radions prestanda använts, och delvist på grund av ett ofullständigt mätresultat.

Full textAbstract:
<p>I samband med de ökade kraven på ett vädersäkrat nät har funderingar kring att placera ut fler frånskiljare/brytare i luftledningsnätet för att reducera medelavbrottstiden för anslutna kunder (SAIDI) kommit fram. I Finland använder man till stor del fjärrmanövrerade apparater för att reducera SAIDI. Rapportens inledande avsnitt innefattar en förstudie om ursprunget till avbrottstid och SAIDI-statistik i Vattenfall Eldistributions nät. En jämförelse med Eldistributions nät och klimatet i Finland utförs och av detta fås olika förutsättningar för nätet i de olika länderna. Som en generell slutsats av väderjämförelsen mellan Sverige och Finland fastställs att Eldistribution i Sverige har sämre förutsättningar vädermässigt när det gäller luftledningsnät. Resultaten från beräkningarna på sex exempelnät visar att den maximala reduceringen av SAIDI uppgår till 36 % och den minimala med 17 % i exempelnäten. Om alla nät skulle gå att bygga om enligt liknande principer skulle det innebära en reducering av Eldistributions mellanspännings-SAIDI med cirka 12 % ifall de 200 sämsta linjerna ur SAIDI-synpunkt kompletterades med fjärrfrånskiljare i motsvarande grad som exempelnäten. Jämförelser av investeringskostnader mellan fjärrfrånskiljaralternativ och kablifieringsalternativ visar att det är mer kostnadseffektivt att bygga om med fjärrfrånskiljare och därför är detta lämpligt om önskan är att så billigt som möjligt reducera SAIDI. Som en allmän rekommendation bör reservmatningar i nätet vara fjärrmanövrerade och dessutom bör linjer ha minst en fjärrfrånskiljare utlokaliserad. Då delas linjen upp i fler fjärrsektioneringsområden vilket förbättrar kundavbrottstiden för linjen. Ifall en linje inte har reservmatningmöjligheter bör det utredas ifall det är möjligt att med acceptabelt stora resurser bygga ihop nätet med ett annat nät för att möjliggöra en reservmatningsväg. Om det finns fler platser på linjen som är lämpliga för komplettering med fjärrfrånskiljare bör dessa utnyttjas för att så prisvärt som möjligt få ner SAIDI på den aktuella linjen. Ett allmänt råd angående antalet fjärrfrånskiljare per linje är svårt att ge men generellt sett är den första fjärrfrånskiljaren mycket mer kostnadseffektiv än de efterföljande. Stolpbrytare (reclosers) bör placeras ut där goda förutsättningar finns för att det skall bli lönsamt. Exempel på sådana platser kan vara vid övergång från kabel till luftledningsnät och innan en sträcka där fel ofta inträffar.</p><br><p>An alternative approach in Vattenfall Eldistribution’s network has evolved from the increased demands on reducing network downtime. Eldistribution are using remote controlled disconnectors / reclosers in Finland to reduce the system average interruption duration index (SAIDI). The initial section of the report includes a study on the source of downtime and SAIDI-statistics in Eldistribution’s network. A comparison with network and the climate in Finland is carried out which indicate different conditions in the two countries. The weather comparison shows that it’s more difficult to use non-insulated overhead-lines in Sweden because of the climate conditions. The result shows a maximum reduction of SAIDI by 36% and a minimum of 17% based on calculations on six example-lines. If all the lines would be possible to build under similar principles it would result in a reduction of Eldistributions SAIDI by approximately 12 % if the 200 worst lines was supplemented with remote controlled disconnectors with a corresponding amount of reduced SAIDI-minutes. Comparisons with cable alternatives show that it’s more cost-effective to invest in remoted controlled disconnectors if the target is a quick and cheap reduction of SAIDI. As a general recommendation the backup powering of a network should be remote controlled and the lines should have at least one outsourced remote controlled disconnector. This will split the line in multiple remote controlled areas, which will reduce disruption time for customers connected to the line. If a line doesn’t have any backup powering it should be investigated whether it’s possible to connect the line to another line to ensure backup-feeding if this is possible to do at acceptable costs. If there are more locations on the line suitable for supplementation of remote controlled disconnectors, those places should be used to get as much reduced SAIDI as possible at a cost-effective level. It's difficult to give a general advice concerning the number of remote controlled disconnectors but the first disconnector is generally more cost-effective than the subsequent ones. Reclosers should be deployed at appropriate locations to be equally costefficient as remoted controlled disconnectors. Examples of such places can be when switching from cable to non-insulated line and before a section where errors often occur.</p>

This bachelor thesis aims to investigate the viability of using two wheeled self-balancing robots for package deliveries. The movement of the two wheeled self-balancing robot resembles the human movement more than a traditional four wheeled vehicle. The goal of the report is to build a selfbalancing robot to investigate how far from the center axis a weight can be added, as well as what the response time of a Wireless Fidelity (WiFi) connection for steering the robot is and how it compares to a Bluetooth connection. Balance of the robot was achieved by using a Proportional-IntegralDerivative (PID) controller with inputs from a gyroscope and accelerometer. Stepper motors were used to maneuver the robot. When the robot was constructed tests were performed to evaluate how far from the center axis a weight could be added. A test was also performed to evaluate the WiFi connection response time with regard to the distance between the operator and the robot, as well as the maximum range and how it compares to Bluetooth. The results showed that a one kilogram weight could be added five centimeters from the center axis, that the response time was around 10-20 milliseconds for a distance up to 35 meters. A WiFi connection has a longer range compared to Bluetooth and also has a lower response time.<br>Denna rapport strävar efter att undersöka möjligheterna av att använda en själv-balanserande robot för paketleveranser. Rörelsen av en tvåhjulig själv-balanserande robot liknar den mänskliga rörelsen mer än ett traditionellt fyrhjuligt fordon. Målet med rapporten är att bygga en självbalanserande robot för att undersöka hur långt från dess centeraxel en vikt kan placeras, samt undersöka vilken responstid som uppnås med en Wireless Fidelity (WiFi)-länk och hur en WiFi-länk jämför med en Bluetooth-länk. Balans uppnåddes genom att använda en Proportional-IntegralDerivative (PID) regulator med input från ett gyroskop och en accelerometer. Stegmotorer användes för att manövrera roboten. När roboten hade konstruerats utfördes tester för att undersöka hur långt från centrumaxeln en vikt kunde placeras. Ett test utfördes för att undersöka responstiden för en WiFi-länk med avseende på avståndet mellan operatör och robot, samt att undersöka den maximala räckvidden och jämföra den mot Bluetooth. Resultaten visade att en vikt på ett kilogram kunde placeras fem centimeter från centeraxeln, att responstiden var ungefär 10-20 millisekunder för avstånd upp till 35 meter. En WiFi-länk har en längre räckvidd än Bluetooth och kortare responstid.

Ziel der vorliegenden Arbeit ist es, die Frage nach Eignung der Technik, des Aufwands, der Schulung und der Vor- und Nachteile eines Einsatzes der Telepathologie in der Schnellschnitt-Diagnostik zu analysieren. Weltweit wurden verschiedene Telepathologiesysteme entwickelt, die zum Teil für den Schnellschnitt verwendet werden können. Auch an der Charité entstanden mit dem 1.ATM-System, 2.dem TPS-System und 3.dem TELEMIC-System, drei technisch völlig unterschiedliche Systeme. Diese Systeme wurden anhand einer retrospektiven Studie hinsichtlich ihrer Einsatzfähigkeit in der telepathologische Schnellschnitt-Diagnostik untersucht. Um die Systeme untereinander vergleichen zu können, wurden 124 histologische Schnellschnittpräparate aus dem Jahr 1999 herausgesucht (ausschließlich Brustgewebe), die von vier erfahrenen Pathologen mit jedem System erneut bearbeitet wurden. Qualitativ wurden mit dem ATM- und dem TPS-System gleichwertige Ergebnisse wie in der konventionellen Schnellschnitt-Diagnostik erreicht. Das TELEMIC-System war qualitativ aufgrund der hohen Rate von Rückweisungen den anderen Systemen und dem konventionellen Schnellschnitt deutlich unterlegen. Bei den Diagnosezeiten zeigte sich eine leichte Unterlegenheit des TPS-Systems gegenüber dem konventionellen Schnellschnitt. Da es jedoch insbesondere als Möglichkeit der Ferndiagnose eingesetzt wird, fallen die bei der konventionellen Schnellschnitt-Diagnostik nötigen Transportzeiten durch einen Kurier weg. Das ATM-System und das TELEMIC-System sind auch ohne Zurechnung der Transportzeiten zeitlich zum konventionellen Schnellschnitt vergleichbare Systeme.<br>Target of the available work is it, the question about suitability of the technique, the expenditure, to analyze the training and the pro and cons of an application of the Telepathologie on fresh frozen diagnostics. World-wide different Systems for telepathology were developed, which can be used partially for the fresh frozen diagnostics. At the Charité were developed three technically completely different systems: 1.ATM-System, 2.TPS system and 3.TELEMIC system, These systems were examined on the basis a retrospective study regarding their serviceability on telepathologische fresh frozen diagnostics. In order to be able to compare the systems among themselves, 124 histological fresh frozen preparations were picked out from the year 1999 (excluding chest tissues), which were again processed by four experienced pathologists with each system. Qualitatively with ATM and TPS system equivalent results as on were achieved conventional fresh frozen diagnostics. The TELEMIC system was qualitatively inferior for the other systems and the conventional fresh frozen diagnostics due to the high rate of rejections. With the diagnostic times an easy inferiority of the TPS system showed up in relation to the conventional fresh frozen diagnostics. Since it is used however in particular as possibility of the remote diagnostics, the feed times necessary with the conventional fresh frozen diagnostics are omitted by a courier. The ATM system and the TELEMIC system are also without addition of the feed times temporally to the conventional fresh frozen diagnostics comparable systems.

Full textAbstract:
Laboratory experimentation plays a critical role in the education of engineers. With the increase of students choosing to obtain their education online through Distance Learning programs, something must be done to allow them to gain practice with experimental techniques. Remote Laboratories (RLs), or laboratory experiments specially constructed for remote use, have the potential to fill this void.
In a "traditional" laboratory experiment, students physically interact with an apparatus to obtain experimental data. Remote Laboratories are meant to offer a similar learning experience that is equivalent to, or as close as possible to the physical one, by allowing a user to control the apparatus from a remote location using mechatronic control hardware, integrated with data acquisition software. Studies have shown there is no significant difference with regard to meeting educational outcomes between students who performed an experiment remotely versus those who carried out the same experiment in-person.
The focus of this thesis is on the development of a framework for developing and implementing Remote Laboratories. To do this, this research introduces advances in the following areas:
a) Identifying the educational differences between traditional and Remote Laboratories.
b) Developing a method for comparing student perceptions about RLs and their laboratory reports through surveys and laboratory report grading.
c) Creating a standard Information Technology protocol for hosting and conducting remote experiments.
d) Investigating alternative uses for RLs.
e) Proposing new methods to best mimic the physical interactions of traditional laboratories.
f) Creation of functioning Remote Laboratories.
g) Analyzing the findings of their use in a classroom setting.
A comparison of surveys and laboratory reports between groups that conducted remote experiments and those which conducted traditional experiments over a period of 4 semesters suggest that RLs have the potential to be used to achieve the same educational outcomes as traditional laboratories.

På avdelningen Medicinsk Teknik-Forskning och Utveckling på Norrlands Universitetssjukhus (MT-FoU) pågår en utveckling av ett rörelsemätsystem (MoLab) som syftar till att ge kvantitativa data från individer med nedsatt rörelsefunktion. Denna information kan fungera som underlag för behandling och användas för att utvärdera uppföljning av behandlingar. Mätsystemet begränsas idag av att det är beroende av en accesspunkt med tillhörande lokalt nätverk för att föra över data till insamlingsdator via TCP/IP-protokollet. Examensarbetet syftar till att öka mätsystemets mobilitet genom att inkludera en portabel och trådlös mätlösning utan krav på stationär accesspunkt och insamlingsdator vid insamlingstillfället. Med ett mer mobilt mätsystem kan data inhämtas från individer i dennes autentiska och vardagliga miljö. En lokal lagringsyta har kopplats till sensorenheterna och användargränssnittet utgörs istället av en fjärrkontroll, som startar och stoppar mätningar. Fjärrkontrollen fungerar också som en accesspunkt som sensorenheterna ansluter till och som vidarebefordrar start- och stoppsignaler via UDP-broadcast från fjärrkontroll till alla uppkopplade sensorenheter. Vid given stoppsignal överförs sensordata till fjärrkontrollen för efterföljande lagring på dess interna minneskort. Det är viktigt att mätningarna sker synkront mellan sensorenheterna, där startsynkroniseringen kan kvantifieras som tidsdifferensen mellan sensorenheternas mätstart. Med metoden som föreslås i detta arbete, hamnar startsynkroniseringen väl under ett väldefinierat tröskelvärde på 2 ms som också fanns implementerat i MoLab och är därför en tänkbar metod för att utöka mobiliteten för MoLab.<br>The department of Biomedical Engineering Research and Development at University Hospital (MT-FoU) is developing a motion measurement system (MoLab) that aims to provide quantitative data from individuals with impaired mobility. This information can serve as a basis for treatments and used to evaluate follow-up of treatments. The measuring system is today limited by the fact that it is dependent on an access point and associated local network to communicate data to an evaluation computer via the TCP/IP protocol. This is a bachelor thesis that aims to give this measuring system greater freedom to measure without dependence of a stationary access point and evaluation computer. With a more mobile system, data can be obtained in a more authentic and everyday environment for the individuals to be measured. An internal memory has been connected to the inertial sensor devices, and the user interface is instead a remote control, which starts and stops measurements. The remote-control acts as the access point which the sensor devices connects to and start and stop signals are transmitted via UDP broadcast from the remote-control to the sensor devices. In case of a given stop signal, sensor data is transferred to the internal memory of the remote control. It is important that the measurements take place synchronously where the synchronization can be quantified as the time difference between the sensor devices at the measurement start. With this method, start synchronization ends up well below a well-defined threshold value of 2 ms that was also implemented in MoLab, giving it greater mobility.

The control group (no RIPC) represented standard clinical practice. Left and right ventricular biopsies were collected before CPB and at the end of ischaemic cardioplegic arrest. Blood samples were collected before, during, and after the operation. Results: Between March 2012 and April 2014, 124 patients agreed to participate in the study; 64 and 60 patients formed the CABG and AVR populations, respectively, and were randomised to receive RIPC or sham treatment. There were no differences in troponin release between groups (geometric mean ratio 0.92 (0.75,1.10), p=0.9; and 0.9 (0.35,1.44), p=0.65 CABG and AVR respectively). The postoperative course in each group was similar with no mortality. There were no significant differences in phosphorylation potential or energy charge in left and right ventricle biopsies or in circulating inflammatory markers between groups. No serious adverse events were reported. Conclusions: RIPC did not confer significant cardioprotection as measured by troponin I release. This result was possibly related to the inability of the study to stratify anaesthesia regimens. Both RIPC and Tru-Cut ventricle biopsy procedures were safe.

Rapporten är skriven för att dokumentera den befintliga installationen av ballast-, läns- och brandsystem ombord på fartyget M/S Calmare Nyckel. I enlighet med uppdragets specifika-tioner kommer även förslag på förbättringar att presenteras. Förslagen bygger till största del på fakta från en leverantör av ventilkomponenter och av klassen ställda krav på installationen. Förbättringarna beaktar i huvudsak minskade risker och ökad säkerhet. De största skillnaderna med de nya förslagen är att länsvattensystemet skiljs från de övriga systemen, de viktigaste funktionerna fjärrstyrs med hjälp av pneumatik och systemets komponenter märks enligt branchstandard.<br>This report is produced to document the existing installation regarding the ballast, bilge and fire system aboard the vessel M/S Calmare Nyckel. According to the specifications of the assignment a proposal regarding improvements will also be presented. The suggestions are mainly based on data from a supplier of valve components and the demands put up by the classification society. The improvements are considered with reduced risk and increased safety in mind. The main differences in the new proposals are the separation of the bilge system from the other two systems, that the most vital functions can be remote-controlled by pneumatics and that all components are marked according to industry standard.

Finding missing people and obtaining an overview of complex emergencies is very demanding and requires costly resources. I have on a few occasions sought after my grandfather, who, when he got Alzheimer, liked to go for a stroll at night (!) when my grandmother was sleeping. Those kind of situations are very stressful, especially a cold winter night. During my first 25 years I was part of a dedicated outdoor culture with countless ski trips, mountain hikes, mountain bike trips and many hours in primarily Swedish nature. It happened on a few occasions that we came in contact with people who worked with rescue operations in this type of environment. It could be about hikers who strayed away or been injured in the inaccessible nature, lost skiers in the mountain massifs around Riksgränsen, berry pickers in the Västerbotten forests etc. There are many examples of this type of situations and it's reflections on these scenarios and similar current problem which is the basis for this project. Every year, about 7000 people are reported missing in Sweden. Of these remains about 30-35 vanished. Globally, the figure is huge. Earthquakes, floods and other hit by natural occurs despite various preventive measures. There are many occasions where the search, reconnaissance and location of individuals as well as physical problems play a critical role, but where human capacity seldom is sufficient. Search party chains (organized by organisations like Missing People) requires significant human resources and costs precious time, police helicopter reconnaissance is economically very costly, not environmentally friendly and involves a significant margin of error. With these statements as background, I would look at the possibility of creating a thorough design solution that contributes to people in need can be located, provided security and helped significantly faster than today without requiring significant resources. With this as a backdrop, I wanted to create a concept that would contribute to that more people were found and could be saved. Through an extensive research of how a rescue operation is conducted, interviews with police and Missing People, as well as observations during actual operations, I identified a few main problem areas that my concept generation would center around. Together with my sponsor, we wanted to create something that can best be described as a robotic eagle with hyper vision, long flight time and a positive association for the victim. The result is Aetos (Greek for eagle). A modular drone-system with innovative features to handle with long flights and demanding rescue missions. Thanks to an aerodynamic shape and a remote-controlled system Aetos requires minimal resources to create overview and help in locating the missing person. We want to save lives, and it can Aetos that.

In recent decades human workers in manufacturing and overall industry have largely been replaced with robots and automated machines, but there are still plenty of tasks where human cognition is necessary. This paper presents the development of a wireless robotic arm controlled by a human arm, allowing both for the combination of a robotic arms strength to be combined with a humans cognition, and also for a human to execute dynamic tasks without being present. An application suited for work in toxic or otherwise harmful environments. This was accomplished by using a controller in the form of an exo-skeleton attached to the operators right arm and connected to the robotic arm through a transmitter. The controller measures the movements in each joint using potentiometers and the robotic arm mimics these movements. A glove with a flex sensor on the index finger was then attached to the controller to measure the finger motions. All the information containing the angle of rotations are sent wirelessly to the robotic arm using Arduino Uno and transceiver modules. The robotic arm received the information through another set of Arduino Uno and transceiver module which made each servomotor on the robotic arm to move accordingly. The result showed that the robotic arm could imitate the operator’s arm very well and was able to grab and move dierent objects with dierent weight and surfaces. The wireless control was reliable and could control the robotic arm while being in a dierent room, making it possible to use this robot for harmful environments for humans.<br>Under senare årtionden har mänskliga arbetare inom tillverkning och industri över lag i stor utsträckning ersatts av robotar och automatiserade maskiner, men det finns fortfarande uppgifter som kräver mänsklig tankeförmåga. Denna rapport presenterar utvecklingen av en trådlös robotarm styrd av en människas arm, vilket möjliggör både att kombinera en maskins styrka med en människas intelligens, samt för en människa att utföra dynamiska uppgifter utan att vara närvarande. En applikation lämplig för arbete i farliga miljöer. Detta uppnåddes med en styrenhet i form av ett exo-skelett fastsatt på operatörens högra arm och kopplad till robotarmen genom en sändare. Styrenheten mäter rörelserna i varje led med potentiometrar och robotarmen härmar dessa rörelser. En handske med en flexsensor på pekfingret fästes sedan på styrenheten för att mäta fingerrörelsen. All information som innehåller vinklar skickas trådlöst till robotarmen med hjälp av Arduino Uno och transceiver moduler. Robotarmen mottog informationen via en annan uppsättning Arduino Uno och transceiver modul som fick varje servomotor på robotarmen att rotera i enlighet. Resultatet visade att robotarmen kunde imitera operatörens arm väl och kunde bära olika föremål med olika vikter och ytor. Den trådlösa styrningen var pålitlig och kunde styra robotarmen från ett annat rum, vilket gör det möjligt att använda denna robot i skadliga miljöer för människor.

Full textAbstract:
Other than mobile hydraulics and high voltage switchgears, Bucher Hydraulics is also involved in the less-known area of hydraulic lifts. In fact, Bucher Hydraulics did invent the electronically controlled lift valve in the 1970s. Since then, Bucher Hydraulics developed a wide line of products for hydraulic elevators, such as valves and power units. In 2012, this valve family included various sizes, pressure ranges, systems with constant motor speeds, inverter-driven motors, energy-efficient solutions with hydraulic counterweight, as well as customized solutions. As the common principle, all these solutions apply an electronic closed-loop control that uses a volumetric flow sensor and a proportional actuator. Since 2012, Bucher Hydraulics is substituting this valve family with a new generation, the iValve. Every iValve uses several self-teaching algorithms to adapt to its environment. Their on-board and cabinet electronics control solenoid currents and measure flow, pressure, and temperature. These features enable the iValve to self-monitor, to adapt to operating parameters, and to analyze and log information about itself and the attached system. This report on a highly specialized product is meant to provide inspiring insights.

Term of remote-lab is certain types of laboratories which practical experiments are directedfrom a separate area by remote controller devices. This study is part of developing andupgrading advanced vibration remote laboratory. In the new remote lab, users have theability to measure the dynamic characteristics of the test object similar to the current existingremote lab. But in addition to current existing remote lab, they are capable to modifydynamic properties of the test object remotely by attaching vibration test instruments; such asa block of mass, spring-mass or non-linear spring. Doing several accurate experimental testsremotely on the test object are the toughest issues we faced as designers. In creating anddeveloping of this remote-lab, number of different approaches was adopted for producingwell-defined tests. Also, instead of implementing routine devices and techniques for regularvibration laboratories, the new prototypes were designed by finite elements method (FEM)and LABVIEW. For instance, the desirable test object, the attachment mechanism, usefulapplications, and proper software for managing via internet were prepared.

In today’s society the electric grid has become one of the most important infrastructures and industries as well as other infrastructures, and individuals rely on its functionality. The unavailability of electricity caused by outages is increasingly rare but when it occurs it can have serious consequences. An electric grid’s reliability is now a requirement, not only from customers but also from the regulatory authority.The electric grid in Stockholm is owned and operated by Ellevio AB. Over the past decade the reliability, measured in SAIDI (System Average Interruption Duration Index), in the area has deterioated, mainly due to failures of the medium voltage grid (11- kV, MV). The network structure on the MV- grid consists primarily of two parallel medium voltage cables each of which acts redundantly to its pair cable. The technique, called dual cable structure, works most optimally with substations with automatic switching, which automaticly switch over to the redundant cable when failure occurs. However substations without this automatic switching are widely used resulting in a longer interruption time. Another network structure is the ring or loop structure, which still has redundancy, but when failure occurs a load- break switch must close so that the grid can be fed from another direction. The substation in the loop structure can also be remotely controlled, making the load-break swith operable from the control center, resulting in a shorter interruption time.This thesis evaluates and compares different network structures consisting of dual cable with automatic switching and loop structure with remotely controlled substations, based on economy and reliability, on Stora Essingen. The two structures have been designed in the network information system program Trimble NIS and divided into two different environments; one developed and one undeveloped environment. The results show that the technical solutions in network structures of MV- grid do not necessarily mean major differences in economy nor reliability, rather the choice between few but long interruptions and many but short interruptions is central. Results show however that a combination of the dual cable structure with remotely controlled substations in the undeveloped environment is economically motivated while the reliability can be maintained at the same tame.

In today's world, security, wellbeing and accommodation has gotten exceptionally imperative than before. As the reliance on innovation increments, individuals require the capability to contemplate trivial errands and need to focus on other pertinent issues. This sort of interest must be met by a framework equipped for rapidly, exactly, and dependably translating the needs of the client and actualizing suitable movements independently. The Remote Controlled Garage Door exploit the utilization of current innovations to give such a framework. The general idea driving is to actualize a framework where the client is no more fundamentally answerable for deciding the activity, yet rather an order module screens the movement, the garage door needs to be performing and makes the fitting modification. In an age where no one has much time for things like coming out of the car and opening garage door, a remote control garage door steps up for the solution of their problem. The research project for a garage door that can be opened with a mere touch of a remote control button is studied, reviewed and its prototype has been developed. For the development purpose the problems faced by the users are identified, detailed specifications of the product parts are done and a working prototype has been fabricated.
