One of the reasons is that the value of new technologies is often compared “in isolation” (i.e., a new technology is compared in terms of how it improves the performances of an existing technology). Opportunities are missed for technologies which may present a lower level of performance compared to an existing technology, but that provide higher benefits when looking at the behaviour of the whole system over the lifecycle (e.g., in production, use or service). This is because novel technologies - of radical nature - establish new interactions and linkages with other elements of the system in ways that are unprecedent.  </div> <div>This presentation highlights, through real-life examples from product development projects, the difficulties of assessing value when new technologies from different domains are integrated into advanced products and systems. Also, the presentation describes how these difficulties can be solved through the application of value-driven design techniques, in which engineering-based models are combined with financial-based models to support collaborative decision-making during the early product development phases. </div></div> <div><br /></div> <div><a href="/en/Staff/Pages/massimo-panarotto.aspx" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />More about Massimo Panarotto</a></div> <div><br /></div></div></div>Tue, 02 Mar 2021 10:00:00 +0100https://www.chalmers.se/en/areas-of-advance/ict/news/Pages/Call-for-ICT-seed-projects-2022.aspxhttps://www.chalmers.se/en/areas-of-advance/ict/news/Pages/Call-for-ICT-seed-projects-2022.aspxCall for ICT seed projects 2022<p><b>Call for proposals within ICT strategic areas and involving interdisciplinary approaches.​</b></p><h3 class="chalmersElement-H3">Important dates:</h3> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div><ul><li><b>Submission date: </b>April 29, 2021</li> <li><b>Notification:</b> mid-June, 2021</li> <li><b>Expected start of the project:</b> January 2022</li></ul></div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <h3 class="chalmersElement-H3">Background</h3> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div><b>The Information and Communication Technology (ICT) Area of Advance</b> (AoA) provides financial support for SEED projects, i.e., projects involving innovative ideas that can be a starting point for further collaborative research and joint funding applications. </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div>We will prioritize research projects that <strong>involve researchers from different research communities</strong> (for example across ICT departments or between ICT and other Areas of Advances) and who have not worked together before (i.e., have no joint projects/publications). </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div>Research projects involving a <strong>gender-balanced team and younger researchers</strong>, e.g., assistant professors, will be prioritized.

The research  is fokused on machines and systems for the production of crushed rock materials. Applications can be found within the mining and mineral industry and the aggregate production. CRPR is internationally acknowledged within modelling of performance and wear in cone crushers, modelling of screens and optimization of crushing plants facilities.​</b></p><strong>Popular science summary</strong>​<div><span style="background-color:initial">What is trending today? Of course, it is sustainability in society concerning the resources we consume as humans. One such resource is aggregates and minerals products, which is the foundation of infrastructure development. Looking at the statistics, the consumption of aggregates in Sweden is about 100 million tons every year, consisting of approximately 90% crushed rock.</span></div> <div><br /><span style="background-color:initial"></span><div>To produce aggregates, the rock material needs to be crushed and screened in different stages, which are often high energy-consuming processes. One way to minimize energy consumption is to improve production efficiency. This can be done by analyzing data from the operation and using different simulation platforms to improve equipment utilization.</div> <div>One of the main classification processes applied in the industry is screening with vibratory screens. A vibratory screen’s main functionality is particle separation, which is a function of gravity, the properties of the granular material, equipment geometry, and the screen’s relative motion. Discrete Element Method (DEM) has been used to study particle behaviour and it is a suitable tool for studying the screening performance. The particle-to-particle and particle-to-geometry interaction can be studied using DEM in a way that is impossible to achieve with physical experiments.</div> <span style="background-color:initial">By using DEM simulation, the fundamental understanding of how to improve screening efficiency can be expanded. The advantage of using simulations instead of experiments to improve screening performance is minimizing cost and energy consumption which is one step toward sustainability. Another advantage is that DEM simulations provide practical feedback when designing the vibratory screen. This allows the designer to determine the correctness and efficiency of a design before the screen is constructed.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><div><strong>Public defence</strong></div> <div>2021-03-19 09:00 -- 12:00</div> <div>Examiner: Magnus Evertsson, IMS</div> <div>Opponent: Peter Radziszewski, McGill University</div> <div><a href="https://chalmers.zoom.us/j/69995808030" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Link to defence</a></div> <div><span></span><a href="https://chalmers.zoom.us/j/69995808030" target="_blank">​</a><span style="font-family:calibri, sans-serif;font-size:11pt;background-color:initial">Password: 586970</span><a href="https://chalmers.zoom.us/j/69995808030" target="_blank">​</a></div></span><span style="background-color:initial"> <div><br /></div> <div><br /></div> <div><a href="https://research.chalmers.se/en/publication/522403" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the thesis</a></div> <div><a href="https://www.linkedin.com/in/ali-davoodi-0b78454a" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Ali Davoodi on Linkedin</a><a href="https://research.chalmers.se/en/publication/522403" target="_blank"></a></div> <div><br /></div></span></div> <div><span style="background-color:initial"><br /></span></div> ​Tue, 23 Feb 2021 00:00:00 +0100https://www.chalmers.se/en/departments/ims/news/Pages/Production-individualization.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Production-individualization.aspxProduction individualization: The future of production for a higher level of quality.<p><b>​Abolfazl Rezaei Aderiani, Doctoral Student at Product Development IMS, defends his doctoral thesis.

As quality problems and late changes in the design and the production of the product can be extremely costly, much can be gained from discovering and addressing problems as early as possible using simulation. This holds specifically true when deformable 1D objects, such as electrical cables and hydraulic hoses, are involved. These types of objects are slender, or one-dimensional (1D), and are usually significantly deformed when subject to external forces and moments. This may cause quality problems and unexpected contact with other objects during both the production and the life-span of a product. </span><div><br /></div> <div>This thesis presents a set of novel methods for virtual design, planning and verification regarding deformable 1D objects. The methods allow for automatically finding a routed design of the object, verifying the routed design with respect to both geometrical variation and assembly and improving operations in production with respect to deformation. The methods rely on an efficient simulation model based on rod theory for computing deformations in accurate agreement with reality. As a result, the methods are today used at several global companies in the automotive industry, including Volvo Cars, BMW and Ford Motor Company.

In her research she focuses on Additive Manufacturing. Online presentation.</b></p><strong>​</strong><span style="background-color:initial"><strong>Popular Science Summary</strong></span><div>Significant growth of additive manufacturing, also called 3D printing, during the last decade, caught the attention of various industrial segments and disrupted traditional manufacturing approaches. Complex-shape high-performance components can be produced with geometries not feasible using conventional manufacturing technologies, with high material utilization and short time-to-market. Several technological solutions under the additive manufacturing umbrella allow for the processing of many different materials, from metals to polymers and composites.</div> <div>In metal additive manufacturing, laser powder bed fusion (L-PBF) represented the largest share of the market, approaching 10000 systems installed worldwide. The most popular materials are Ti-6Al-4V, stainless steels, and nickel-based alloys, followed closely by aluminium alloys. This process uses the energy from a laser to selectively melt a bed of powder particles of tens of microns in size, slightly smaller than a human hair. This step is repeated in a layer-wise manner to build a 3D component. Great effort is devoted to developing robust L-PBF process and the material portfolio to address a wide range of applications. Integration of additive manufacturing within industrial production schemes, making it an economically interesting manufacturing alternative, is another important challenge nowadays. This demand is also associated with the need for productivity increases and material properties’ control. In this context, gaining a better understanding of the physical phenomena involved during L-PBF and optimizing the process is necessary. </div> <div>This thesis focuses on the effect of the process atmosphere on the interaction between laser and powder bed and the resulting microstructure, process stability and productivity, as well as, spatter formation and their characteristics. Typically argon or nitrogen are used as processing gases, filling the process chamber where the laser scans the powder bed. This variable, the process gas, has been largely neglected in favour of first order parameters, such as the laser power or speed. This work demonstrates a strong influence of both the type of gas and the purity achieved in the process chamber on the microstructure and properties of the produced material, as well as, the powder exposed to the processing conditions. In addition, the results highlight that guidelines associated with the process atmosphere have to be formulated considering the sensitivity of the alloy produced. Furthermore, helium and argon-helium mixtures were investigated as an approach to stabilize the process and showed potential toward increasing process stability, allowing to increase build rates and thus productivity.</div> <div><br /></div> <div><div><span style="font-weight:700">Public defence</span></div> <div>2021-03-25 09:00</div> <div>Examiner: Lars Nyborg, IMS</div> <div>Opponent: ​Professor Eric Jägle, Institute of Materials Science, University of Bundeswher, Munich , Germany​</div></div> <div>Link to presentation: TBA</div> <div><br /></div> <div><b><a href="https://research.chalmers.se/en/person/?cid=pauzon" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more</a></b></div> <div><br /></div> <div><br /></div>Thu, 04 Feb 2021 00:00:00 +0100https://www.chalmers.se/en/departments/ims/news/Pages/Improving-geometrical-quality.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Improving-geometrical-quality.aspxImproving geometrical quality with joining sequences<p><b>​Roham Sadeghi Tabar, Doctoral Student at Product Development​ IMS, defends his doctoral thesis.

But there is a risk that the term biodegradable plastics can lead to confusion for policymakers and customers, since most biodegradable plastics are designed to degrade only in special industrial composting facilities. A report has now been published that gives a scientific view on the use of biodegradable plastics in the open environment.</b></p><div>​Biodegradable plastics can only help solving the growing plastic waste problem if it’s handled the way it was designed. A perspective here is to label as biodegradable if it can be fully broken down by microorganism. Such full biodegradability is not always the case with conventional biodegradable plastics. The effectiveness of biodegradable plastics is highly dependent on the environmental conditions. If the necessary microorganisms and other circumstances such as the right temperature is missing, then the plastic will not degrade in a reasonable time period. Most biodegradable plastics today cannot just be left in an open environment for degradation. So, it is very important to understand that biodegradable plastic will not automatically solve the plastic waste problem, but it can be part of the solution if managed correctly.</div> <div> </div> <h2 class="chalmersElement-H2">Policy recommendations on biodegradable plastics</h2> <div> </div> <div> The report <a href="https://www.sapea.info/topics/biodegradability-of-plastics/">Biodegradability of Plastics in the Open Environment</a>, written by a Group of Chief Scientific Advisors based on scientific evidence reviewed by the Science Advice for Policy by European Academies, gives several policy recommendations. First is limiting the use of biodegradable plastics in the open environment to specific applications for which reduction, reuse, and recycling are not feasible. Second, the report wants to see support for the development of coherent testing and certification standards for biodegradation of plastics in the open environment. Thirdly it is also necessary to promote the supply of accurate information on the properties, appropriate use and disposal, and limitations of biodegradable plastic to relevant user groups.</div> <div> </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Konstruktionsmaterial/AntalBoldizar.jpg" alt="Antal Boldizar" class="chalmersPosition-FloatLeft" style="margin:5px 20px;width:167px;height:209px" />Professor <a href="/en/Staff/Pages/antal-boldizar.aspx">Antal Boldizar</a>, researching on environmentally adapted engineering polymers at Chalmers University of Technology, is one of the working group members in the advisory board that produced the report.</div> <div><br /></div> <div> </div> <div><em>Who do you think should read this report and why?</em></div> <div><span style="font-size:11pt;line-height:107%;font-family:calibri, sans-serif">– </span>As this report gives a rather broad perspective on the aspects of biodegradable plastics, I think it could be of general interest for many readers.

Lydia is a part of the Systems Optimization Lab headed by Prof. Michael Kokkolaras. Lydia has been working on industrial research since the beginning of her graduate studies as a master’s student. During her PhD and under the supervision of Prof. Michael Kokkolaras, Lydia worked closely with GKN Aerospace in Trollhättan to develop design strategies to address the aerospace industry’s needs for adaptable parts that satisfy changing requirements in an economic manner. Additive manufacturing was a key enabler of these methods. Through his great experience and connections in the industry, Prof. Ola Isaksson at Chalmers provided the support and resources needed for Lydia to work closely with GKN. This has helped broaden her knowledge about the inner workings of the aerospace industry. Prof. Isaksson’s team of researchers at the Systems Engineering Design research group at the department of Industrial and Materials Science, hosted Lydia for the summers of 2017, 2018, and 2019 resulting in several publications and successful technology transfers at GKN aerospace. Lydia’s research interests are in the area of design optimization, lifecycle cost modeling, system dynamics, and design for changeability.<div><br /></div> <div><span style="font-weight:700">Abstract​</span><br /><div><div>The thesis presents a design decision framework for assessing alternative manufacturing and remanufacturing strategies from both technical and business perspectives. The proposed methods enable such considerations in the early product design phases, where a sufficient degree of freedom exists to identify component design solutions that can accommodate dynamic requirements throughout a product's life.</div> <div><br /></div> <div>The first method presented in this thesis considers the potential use of additive manufacturing in life extension strategies by examining the impact of design decisions on component lifecycle cost. An optimization problem is formulated and solved to minimize lifecycle cost with respect to design variables related to remanufacturing.</div> <div><br /></div> <div>The second design decision method proposed enables the consideration of a design margins approach to satisfy changing requirements through optimizing component lifespan for different lifecycle scenarios. A dynamic lifecycle cost model that considers additive remanufacturing to quantify corresponding costs and benefits is developed. A nested design optimization problem is then formulated to determine the optimal component lifespan range that minimizes overall cost while maximizing performance. The proposed methods are demonstrated using a turbine rear structure, an aeroengine structural load-bearing component. The life extension of the turbine rear structure is achieved through the additive deposition of a circumferential stiffener on the outer casing. </div> <div><br /></div> <div>Design and manufacturing scenarios have a significant impact on the efficiency of the manufacturing process. Therefore, an integrated design-manufacturing decision metric is proposed to allow assessment of products based on both the geometrical information obtained from a part’s computer aided design file and its manufacturing scenario. The developed metric can be used as a proxy of build time and manufacturing cost assisting in the product’s design optimization and development processes. Two examples of jet engine components are used to illustrate the use and benefits of the proposed decision metric.</div> <div><br /></div> <div>The three presented methods support design decision-making while considering the potential use of new technologies in addressing changing requirements throughout a component's life.</div> <div><br /></div> <div><strong>Public defence</strong></div> <div>Thesis Supervisor: Prof. Michael Kokkolaras</div> <div>Date: March 1, 2021</div> <div><div>Unfortunately the defense will not be broadcasted on Youtube as planned. <span style="background-color:initial">​</span></div></div></div> <div><br /></div> <div><a href="mailto:lydia.lawand@mail.mcgill.ca" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Contact Lydia Lawand</a></div> <div><br /></div> <div><div><a href="https://www.mcgill.ca/mecheng/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />More about the Department of Mechanical Engineering, <span style="background-color:initial">McGill University</span></a></div> <div><a href="/en/departments/ims/research/product-development/Pages/systems-engineering-design.aspx" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" /><span style="background-color:initial">More about the Division of </span><span style="background-color:initial">Systems Engineering Design, IMS​</span></a></div></div> <div><br /></div></div></div> ​​Thu, 28 Jan 2021 00:00:00 +0100https://www.chalmers.se/en/departments/ims/news/Pages/Datadriven-throughput-bottleneck-analysis-in-production-systems.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Datadriven-throughput-bottleneck-analysis-in-production-systems.aspxData-driven throughput bottleneck analysis in production systems<p><b>​Mukund Subramaniyan, Production Systems​ IMS, new doctor IMS.</b></p><strong>​</strong><div><span style="background-color:initial"><strong><img src="/SiteCollectionImages/Institutioner/IMS/Produktionssystem/Abstract%20Figure_Thesis%20web.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /></strong></span></div> <div><span style="background-color:initial">Summary figure: &quot;</span><span style="background-color:initial">Data-driven throughput bottleneck analysis in production systems&quot;</span></div> <div><span style="background-color:initial"><strong><br /></strong></span></div> <div><span style="background-color:initial"><strong><br /></strong></span></div> <div><span style="background-color:initial"><strong><br /></strong></span></div> <div><span style="background-color:initial"><strong><br /></strong></span></div> <div><span style="background-color:initial"><strong><br /></strong></span></div> <div><span style="background-color:initial"><strong><br /></strong></span></div> <div><br /></div> <div><span style="background-color:initial"><strong><br /></strong></span></div> <div><strong></strong><span style="background-color:initial"><strong>Public defence - </strong></span><b><span></span>Mukund Subramaniyan​</b><div>2021-02-12 10:00</div> <div>Opponent: Amos Ng, University of Skövde, Sweden</div> <div>Examiner: Johan Stahre, IMS</div> <div><br /></div> <div><strong style="background-color:initial">Popular science text</strong><br /></div> <div> <div>My thesis offers a series of data-driven solutions that can provide a multifold increase to a company's bottom line by eliminating throughput bottlenecks in the factory. Today manufacturing companies' factory floor productivity is alarmingly low at 50%. Practitioners are exploring new ways to increase factory floor productivity. One way to increase productivity is to get higher factory throughput. Some machines constraints the throughput on the factory floor. These machines are called throughput bottlenecks. When practitioners eliminate throughput bottlenecks, they can get higher throughput. But how can practitioners find, analyze, and eliminate throughput bottlenecks? Currently, practitioners spend a lot of time (sometimes hours or days) on the shop floor to search for bottlenecks and make ambiguous experience-based decisions. But this can be changed using digital solutions. How? My research answers this question. In my thesis, I build data-driven approaches to analyze throughput bottlenecks in less than seconds. The input to a data-driven approach is digital machine data. Then, the data-driven approach quickly analyses the digital data using artificial intelligence techniques. The outputs of a data-driven approach are the insights on throughput bottlenecks.</div> <div><br /></div> <div>Within the thesis, I propose four data-driven approaches for different types of throughput bottleneck analysis. First, I present different data-driven approaches to identify historical throughput bottlenecks. With these, practitioners can quickly identify the bottleneck location in a production system. Second, I propose a data-driven approach to diagnosing historical throughput bottlenecks. It will help to understand the possible root-causes of the throughput bottlenecks. Third, I offer a data-driven approach to predict throughput bottlenecks for the next production day. It will help to take proactive actions on throughput bottlenecks. Fourth, I propose a data-driven approach to prescribe actions on predicted throughput bottlenecks. It will give information on specific measures one can proactively perform on predicted throughput bottlenecks. In sum, these data-driven approaches will help practitioners to make faster, confident, and informed decisions on throughput bottlenecks, which will help to maximize the throughput from production systems.</div> <div><br /></div> <div>Overall, data-driven approaches are similar to GPS. People use GPS to find the best way. The GPS eliminates blind alleys. Similarly, practitioners can use data-driven approaches to eliminate throughput bottlenecks and create a more predictable and better factory environment without surprises.</div> <div><br /></div></div></div> <div><a href="https://research.chalmers.se/en/publication/521942" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more​</a></div> <div><a href="https://www.linkedin.com/in/mukundsubramaniyan/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Mukund on Linkedin</a></div> <div><a href="https://www.smukund.com/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />https://www.smukund.com/​</a><br /></div> <div><br /></div> ​Mon, 18 Jan 2021 00:00:00 +0100https://www.chalmers.se/en/departments/ims/news/Pages/Meltprocessing-and-properties-of-thermoplastic-composites-.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Meltprocessing-and-properties-of-thermoplastic-composites-.aspxMelt-processing and properties of thermoplastic composites based on ethylene-acrylic acid copolymer reinforced with wood nanocellulose<p><b>​Abhijit Venkatesh, Doctoral Student at Engineering Materials​ IMS, defends his doctoral thesis.

The main source of cellulose are plants and trees, with a global annual synthesis of 100 billion tons, and hence abundantly available in nature. Cellulosic materials are also biodegradable, renewable, inexpensive and have been used as structural material for centuries while still covering a large part of the industries like paper, forest products, textiles, etc. Sweden has always used cellulose as raw materials in various applications and with the stricter regulations from EU, the industries are opting for more sustainable materials/solutions. This has worked in the favour of wood-based materials which can be used as an inexpensive reinforcing material in thermoplastic composites.</div> <div>A composite material contains two (matrix and reinforcement) or more (additives) components that are combined to obtain a material with properties different than the individual components. Wood is nature’s composite where lignin is the matrix and cellulose are the reinforcement. The reinforcement provides structural integrity and improves the properties, which is exactly what cellulose does in trees and plants.  In wood-polymer composites, the cellulose has been used as reinforcement, for decades, to strengthen the polymer matrix. However, an interest has been rekindled due to advancements in cellulose production technology which helps in commercially obtaining nano-sized cellulose reinforcements. Here, the nanocellulose is expected to improve the reinforcing capabilities more than the larger fibers, due to their excellent mechanical properties, resulting in composites with high strength and stiffness.</div> <div>Despite the favourable properties of nanocellulose, it has a major drawback when used as reinforcement in thermoplastics, due to its relatively hydrophilic nature when compared to the usually hydrophobic polymer matrix, which drastically affect the properties. In addition, the main method of producing nanocellulose composites has been through laboratory scale methods and to make the production of nanocellulose composites commercially interesting  on an industrial scale, the feasibility with conventional melt processing technique should be considered. The results from this work helps us improve the understanding of melt processing of cellulose nanocomposites and highlight the importance of process details. It also highlights the possibility of upscaling the production while analysing its impact on nanocellulose modification and the different types of melt processing techniques. In this work, depending on the type of processing method and the hierarchical structure of the cellulose reinforcements used, the composites exhibited an increase in stiffness of up to 21 times than that of the polymer matrix.</div></div> <div><br /></div> <div><a href="https://research.chalmers.se/en/person/?cid=abhven" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more</a></div> <div><br /></div> <div><a href="https://www.linkedin.com/in/abhijit-venkatesh-88820a86" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />​Abhijit Venkatesh​ Linkedin</a><br /></div> <div><br /></div>Mon, 11 Jan 2021 00:00:00 +0100https://www.chalmers.se/en/departments/ims/news/Pages/Promotion-lecture-for-professor-in-Product.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Promotion-lecture-for-professor-in-Product.aspxKristina Wärmefjord new professor in Product and Production development<p><b>Kristina Wärmefjord  gave her lecture &quot;Geometry assurance and non-rigid variation simulation​&quot; for professor  (Swedish: biträdande professor) on January 21, 2021.​</b></p>​<img src="/SiteCollectionImages/Institutioner/IMS/Övriga/div%20nyheter%20o%20kalender/Kristina%20W%20kalendarium.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><br /><span style="font-weight:700;background-color:initial">Title</span><div class="text-normal page-content"><div>Geometry assurance and non-rigid variation simulation</div> <div><br /></div> <div><span style="font-weight:700">Abstract</span></div> <div>Geometry assurance is a way to achieve high quality products, by reducing the effect of variation in design and production.
