This essay focuses on the technical systems and functions behind how a Roman bath operated. I will present a general view by going through each part of the waters path through the bath one by one. Since there is no such thing as a standardised Roman bath I will, under each headline, present the sub subject with a presentation of the workings and then exemplifying through archaeological findings and ancient literary sources.This essay is therefore meant to present a thorough and clear presentation of the technical aspects of a roman bath. The aim is to give the reader an understanding of how a bathhouse worked in general and why. To this I want to present problems that the Romans were faced with and how they solved them..

WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

This essay recognizes and criticizes a commonly held assumption that Corporate Social Responsibility (CSR) functions as a ?savings account of trust? between corporations and consumers. Based on five focus group interviews, the authors discuss how corporations that engage in society can sometimes raise and sometimes destroy the trust of potential consumers. One of our main findings is that CSR seems to raise the expectations among consumers. We then compare this phenomenon with the classical theory of the disconfirmation paradigm.

Our task was to create a virtual test bench for verifying memory addresses in our commissioning body?s models. The purpose with the testbench was that it should be created in such a way that it would be easy to change the device under test without any major changes in the testbench.To solve the problem that the testbench had to be able to verify different devices we had to create a general enviroment for how the testbench had to be composed. By doing an analysis of which com-ponents that are usually included in a testbench and which components that were necessary in our project we came up with a generall enviroment for the testbench. Our result was a testbench with the follwing basic functions:* Read from a file that contains read and write operations to the Device Under Test (DUT).* Apply the stimulus to the device* Read the results from the device* Compare the results with wanted values* Generate a log file which contains information about the simulation result..

I detta examensarbete studeras kommande energikrav för byggnader i Sverige och i synnerhet kraven påspecifik energianvändning. Detta mot bakgrund av EU-kommissionens och EU-parlamentets direktiv,EPBD2, om nära nollenergibyggnader 2020. Därefter bearbetas ett förslag på en nyytterväggskonstruktion som med lägre U-värde än den befintliga ytterväggen ska sänkaFiskarhedenvillans olika hustypers specifika energianvändning. Syftet med sänkningen är att möjliggöraför Fiskarhedenvillan att uppfylla de kommande energikraven.Det är många parametrar som måste uppfyllas och det nya ytterväggsförslaget analyseras förutom urenergisynpunkt även med hänsyn till statik, fukt och kostnad. Beräkningar för statik och specifikenergianvändning har gjorts för ett referenshus.Resultatet av att byta ut den befintliga ytterväggskonstruktionen mot det framarbetade förslaget medca 33 % lägre U-värde gav endast en sänkning med ca 6 % av den specifika energianvändningen.

This final thesis is initiated by the wood fuel department at the Swedish forest company Sveaskog as part of a project which also involves two other final thesises. The overall goal of the project is to investigate Sveaskog´s possibilities to produce and sell different wood fuel assortments in Västerbotten and the southern parts of Norrland. The aim of this thesis is to investigate how much wood fuel Sveaskog can produce in the area during the next five years and what that would cost. Furthermore the thesis will investigate the total possible supply of wood fuel from all other possible producers in the area. Treated assortments are forest residues from final fellings, whole trees from direct wood fuel thinnings, non industrial wood and industrial by-products from sawmills. The main effort to investigate Sveaskog´s production possibilities has been made to calculate the possible annual amount of forest residues and fuel from wood fuel thinnings that can be produced.

Modeling and simulation is growing ever more important in the development of new products. This thesis describes the use of Hopsan for hydraulic modeling and its use in conjunction with Simulink with the intent of using the model in a hardware-in-the-loop setup. A sensor layer has been created in Simulink to emulate all the internal sensors in a modern forklift. The details of using legacy C-code instead of a hardware MCU for a fully simulated environment, software-in-the-loop has been outlined. There are two major routes one can follow implementing software-in-the-loop, exporting the C-functions to CAPL via a export layer or creating an s-function in Simulink.

The task given to us was to develop an industrial wheel with new thinking in terms of fresh design and construction, with the ability to brake. While the produced wheels of today only own the property of total braking, a wish was made to integrate the ability of directional locking.The time spent working with the project has been filled with multiple sketches of ideas and function analysis.Choices of material and ways of construction have been verified by calculations, tests and prototype building. The goal of this thesis has been to develop a unique caster with well thought-out design that would be adaptable to different areas of applications.The result was a hubless wheel with the ability of directional locking before total braking.A prototype of the wheel has been made to show the design and functions..

This essay focuses on the film Joker (2019) directed by Todd Phillips. It examines the narration and the use of music as a narrative device to discuss questions about identification and perception through close textual analysis. The aim is to research this in combination with the film?s complex storytelling and unreliable narration. The essay use several narratological and psychological theories as well as psychopathology.

This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.

This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions: ? Can U-value theory be combined with acoustic theories? ? Can the coefficient of heat be affirmed trough an acoustic measurement? The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units. The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory. The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.
