Modern electronic medical implants have reached a high degree of complexity. This has increased the demands on the communication link with the implant, both regarding the bandwidth and the communication distance. A medical communication system at RF frequencies has been standardised, the Medical Implant Communication System (MICS), which use a frequency allocation of 402 - 405 MHz. This frequency
Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen hos kvinnor i Sverige, men även män kan drabbas. Hos män är det dock en mycket ovanlig cancerform. I Sverige insjuknar cirka 40 män per år av bröstcancer jämfört med cirka 8000 kvinnor per år. Bröstcancer hos män och kvinnor är på många sätt lika. Till exempel är sjukdomstecknen desamma och visar sig oftast som en knöl eller knCancer is today a major healthcare problem worldwide. There are many forms of cancer, which is a genetic disease, believed to result from a multistep process with genetic and epigenetic changes accumulating over time. Breast cancer is one of the most common forms of cancer in women, while it is much more rare in men. Male breast cancer (MBC) exhibits both similarities and differences with female b
The objective of this paper is to investigate how the combustion chamber design will influence combustion parameters and emissions in a natural gas SI engine. Ten different geometries were tried on a converted Volvo TD102 engine. For the different combustion chambers emissions and the pressure in the cylinder have been measured. The pressure in the cylinder was then used in a one-zone heat-releas
In Sweden, almost every county has their public transportation handled by an individual company. The public transportation companies have their own, official, travel planner application. Which means that the appearance and functions of the applications are different. Hence, this master thesis aims to design and evaluate a new travel planner that can be used for the individual companies. The travel
When designing control systems for real applications, it is important to first do testing in a simulated environment, to ensure adequate performance. This is especially important when designing control systems for applications that have high operation costs, e.g., submarines, since late errors in the development can be extremely costly. Saab develops steering systems for submarines. Prior to this
This master thesis has shown multiple uses of the Anoto dot pattern and Anoto pen for different applications. One application is the calibration of the robot tool and work object. Another is the use of an Anoto pen and paper as replacement of the ABB Flexpendant to create a lightweight and intuitive control device to control an industrial robot, experimentally demonstrated for the IRB140 robot arm
Abstract in UndeterminedRobustness of distributed routing policies is studied for dynamical networks, with respect to adversarial disturbances that reduce the link flow capacities. A dynamical network is modeled as a system of ordinary differential equations derived from mass conservation laws on a directed acyclic graph with a single origin-destination pair and a constant total outflow at the ori
Soft tissue sarcomas (STS) are challenging as they represent a morphologically and genetically heterogeneous groups of tumors. A multitude of genetic changes, often in the form of fusion genes, were recognized during the 1980's and now constitute a diagnostic lexicon in several STS subtypes, whereas many of the more common subtypes are genetically complex without distinct alterations. Refined STS
Objectives: The aim of the study was to illuminate the experience of life as next of kin to an elderly person with cancer. Background: Being next of kin to an elderly person with cancer and its impact on everyday life has been sparsely researched. Such understanding is needed to support both the sufferers and their relatives in dealing with issues arising after a cancer diagnosis in old age. Desig
The steel industry in Sweden is responsible for 10% of the annual Swedish CO2 emissions. As a way to abate this sector, H2 Green Steel are establishing a new green steel production site in Boden. Their way of producing steel, through the EAF route and by using hydrogen-reduced DRI will reduce the CO2 emissions by over 90%. Besides iron ore, steel scrap is the most important input raw material for
The existence and staffing of reference desks in academic libraries has been a topic of debate for at least 30 years. As digital library services have grown in significance, some argue that the physical desk no longer serves the needs and wishes of patrons. The use of the academic librarian behind the desk has also been questioned – studies have shown a gain in efficiency when letting student work
The purpose of this explorative study was to analyse five people’s life stories – in a city in the southern part of Sweden – regarding their own experiences of the way into homelessness and their views and experiences of support, assistance and treatment measures from social services, medical service and NGOs. The aim has also been to find out what kind of support and treatment measures the respon
Corporate Social Responsibility (CSR) has emerged to cover the company’s responsibility in their participation in solving social problems. Research has shown that CSR planning and implementation vary significantly between developed and developing countries. Previous literature on CSR were mainly dominated by Western nuances, and they overlooked the implication of socio-cultural aspects in the deve
Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. Based on temperature- and wheel-speed measurements, a mathematical model of
While urban areas are predicted to expand due to population growth, new approaches towards smart solutions in urban infrastructure and transportation are on the rise. With access to new technology, data has been given much attention from municipalities and decision makers. This thesis is interested in how the public sector will utilize the untapped potential of data collection, and what effects th
Global warming is a very much researched and debated topic in the current period as we can see the effects around us. The literature and discussions have pointed to a surface temperature rise of up to 10°C at the poles and around 4°C-7°C around the equator. The effect is more in the northern hemisphere than in southern hemisphere of our planet Earth. The effects of the warming of our environment o
In vehicles there are many issues involving the safety and performance. The safety issues are often regulated by governments, whereas the performance by the customer. One solution to both these issues is to take use of an all-wheel drive system, where a coupling engages and disengages driving axles when needed. Such a solution will, through added traction and stability, increase performance and sa
