Nature provides us with a vast source of inspiration. However, given industrial designers' open-mindedness and inquisitiveness, a surprisingly limited set of nature-derived symbols continues to be popular in this creative discipline. Rather than designing products mimicking nature, it is probably more rewarding designing them based on the natural principles leading to its growth and form. However,
A significant part of our cultural heritage consists of wood. Research on historical wooden structures and artefacts thereby provides knowledge of people’s daily lives and the society in which they lived. Dendrochronology is a well-established dating method of wood that can also provide valuable knowledge about climate dynamics, environmental changes, silviculture, and cultural transformations.

In this study I explore the field of internal business partnering (IBP) and how IT is utilized in supporting these efforts and in supporting an increased awareness. I furthermore explore what the current limitations of today's technology are, and finally, in addition, study a specific collaborative tool, namely a word processing template, and how this should be developed to maximize communicat
Rå biogas är varm, mättad med vatten och innehåller små mängder av korrosiva spårämnen när den lämnar rötkammaren. I detta skick kan gasen inte levereras till uppgraderingsenheten som tar bort koldioxid, vattenånga och andra föroreningar för att leverera biometan som uppfyller fastställda kvalitetskrav. Den höga fuktigheten kombinerat med reaktiva ämnen leder till okontrollerad kondensation och koRaw biogas leaving an anaerobic digester is warm, saturated with water vapor, and contains small amounts of corrosive trace compounds. In this state, the gas cannot be fed directly to an upgrading system, where carbon dioxide, water vapor and other contaminants are removed to produce biomethane that meets a predefined quality. High humidity combined with reactive species promotes uncontrolled cond
Projects with the objective of introducing Finite Element Analysis (FEA) into the early phases of the design process have previously been carried out at the Department of Machine Design, see e.g. the Doctoral thesis by Burman [13]. These works clearly highlight the usefulness of introducing design analysis early in the design process. According to Bjärnemo and Burman [10] the most significant adva
The global steel industry accounts for 8–10 % of global CO2 emissions and requires deep decarbonisation for achieving the targets set in the Paris Agreement. However, no low-emission primary steel production technology has yet been commercially feasible or deployed. Through analysing revisions and additions of European Union climate policy, we show that green hydrogen-based steelmaking in competit
A climatisation controller for a car with multiple objectives is developed, implemented and tested in simulations. The design focuses on electric cars and their specific characteristics. In this context the goal has been to fulfil common comfort and safety standards while having a low energy consumption. The main idea of the control in order to achieve this is to use a simplified model predictive
In this article we discuss the notions of social sustainability and universal design by reflecting on a particular type of architectural element in common space, namely the “social staircases” that serve as multifunctional spaces beyond mere transportation, aiming at social interaction. Through empirical examples, including a detailed analysis of a newly built housing project in Sweden, renowned f
This report is part of a Master Thesis Project in Mechanical Engineering with Industrial Design at the Faculty of Engineering LTH at Lund University. The project was performed in collaboration with Hammarplast Consumer Ab, a Swedish company founded in 1947 manufacturing household items in plastic. Hammarplast Consumer Ab is part of the Orthex group, which is the leading Nordic company within t
The goal of this work is to specify and investigate suitability of a number of selected permanent magnet synchronous machine (PMSM) topologies to be mounted directly on a low pressure shaft (LPS) of a geared turbofan engine. The starting point of the work is to explore the status of electrical machines for more electric engine in order to study different design aspects when identifying and definin
The use of low emissivity windows degrades radio communication. This paperpresents design, manufacturing and test measurements for an energy savingwindow that is transparent to GSM, GPS and 3G radio wave frequencies.A frequency selective structure (FSS) is used in the metallic coating of thewindow to provide the needed transparency that ranges from 900MHz to2GHz. The periodic pattern used for the
This paper focuses on the design and the evaluation of a three-phase permanent magnet synchronous machine (PMSM) that stator core is made of Soft Magnetic Mouldable Composite – SM2C. A radial flux PM machine with modular winding is designed for a high-speed low-voltage automotive application. Manufacturability and a high fill factor of the winding are vital for a low permeability stator core in or
The core objective of this project was to design a controller for a drone (or quadcopter) that would allow the drone to keep a target in the center of a video filmed by a camera mounted on the drone. This was done by controlling the pitch of the gimbal, on which the camera was placed, and the yaw of the entire drone combined with using an image recognition program that could identify the target.
