OTEC-Ett energialternativ för enhållbar ö

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy Solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.

Automatisering av spraytorkningsprocess

ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a Solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

Lagring av flisade skogsbränslen : - med avseende på att minska energi- och kvalitetsförändringar

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the Solution, making it possible to control, in detail, the information?s age as it moves through the system.

Hur kan vi lyssna på de tysta?

The knowledge that citizens have of their own municipality is very useful for the local politicians and planners in the event of such a major reconstruction in the neighborhood. It is the residents in the area that are most affected, and their view on the reconstruction is valuable if the end result will be as good as possible. Since the municipality builds for the citizens, and wants them to enjoy the outcome of the reconstruction as much as possible, it is essential that the municipality get a chance to inspect the citizen?s views and experiences about it in an early stage. If the citizens don?t want to get involved, or if only a few people involve themselves, it will be difficult for the municipality to find a Solution satisfactory to all.

Hållning av kastrerade och icke kastrerade försöksmöss i par som en lösning på aggressivt beteende

Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new Solution was tested in this paper. The proposed Solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

Implementation av ett interface till Emotiv Epoc

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

Pneumatiska artificiella muskler : med hjälp av en robotarm

According to the study [1] several firefighters are killed in action each year. This happens naturally in various ways. One of the major factors is that firefighters often do not know how the environment looks like, for example that a building in an industrial area contains hazardous gas cylinders. Without a Solution, fire-fighters will continue to die in duty. It is therefore important to solve this problem so that we can minimize the risks and save lives.The goal of this project was a control system for pneumatic artificial muscles.

CAMPUS BTH - ett gestaltningsförslag och en studie av begreppet campus

This text answers the questions how do we define what a campus is, how the concept of the campus came to exist and how it is used today, and how the Blekinge Institute of Technology (BTH) campus can be designed according to site conditions and the conclusions drawn from case studies at Chalmers University of Technology and Karlstad University. The purpose of the case studies is to gain insight into their campuses advantages and disadvantages. This finally results in an interpretation of how the Blekinge Institute of Technology campus can be planned. A campus is the area of land on which a college or university and its surrounding buildings resides on. Campus as a concept meant a field at first, it later evolved at American universities due to their design of college campuses.
