Conventionally, light was only used to illuminate the road and help the users to have a clear vision of the road in the darkness but now it has become premium design feature for aesthetic appeasement. Lately users have started to identify the brand of the car by just viewing the light from the lamps. </span></div> <div><span style="font-size:14px"><br /></span></div> <div><span style="font-size:14px">Many car-manufacturers are striving to get a homogeneous intensity of position lights. Light homogeneity has become a major factor under consideration during lamp design and development. Priority is given to the perception of homogeneity by human eye over equipmental data of the same.   </span></div> <div><span style="font-size:14px"><br /></span></div> <div><span style="font-size:14px">This thesis aims to overcome the subjective evaluation of lamp homogeneity by bring in an objective approach and to generate corresponding requirement. The thesis work also aims to generate a verification method that can be integrated to the requirement generated.</span></div> <div><span style="font-size:14px"> </span></div> <div><span style="font-size:14px">Using product development approach and established laws of photometry, an experimental investigation is performed inorder to determine quantifiable limits that assists the requirement. Investigation involves study on various factors that influence homogeneity such as eye perception, distance and angle of judgement, legal requirement, and design intent. The thesis incorporates user study, which served as a foundation for obtaining subjective data and setting the requirement. </span></div> <div><span style="font-size:14px"><br /></span></div> <div><span style="font-size:14px">Threshold values for intensity variation was determined. It was investigated and verified that -12.5\% and +9.5\% were the threshold intensity variation between two regions, violation of which would deem the regions to appear inhomogeneous. The verification of requirement is methodically generated which was specific to the tools that were available. </span></div> <div><span style="font-size:14px"> </span></div> <div><br /></div>https://www.chalmers.se/en/departments/ims/calendar/Pages/Human-Motion-Analysis-.aspxhttps://www.chalmers.se/en/departments/ims/calendar/Pages/Human-Motion-Analysis-.aspxHuman Motion Analysis based on Human Pose Estimation<p>On-line presentation</p><p>​Rinkkhesh Venkatesulu &amp; Shashank Venkatesh Koundinya​ present their master thesis project.

While this is good for assessing an already existing workplace, more accurate information can be obtained with the use of current tracking technology and valuable time can be saved in comparison with the </span><span style="background-color:initial">manual way of observation.</span></div> <div><span style="font-size:14px">This thesis attempts to automate the process of filling in a part of an ergonomic assessment in the AviX software from posture data. The work done also delves into the method of obtaining this posture data automatically from the use of appropriate systems. An exploration into the existing ergonomic standards pertaining to the scope of the thesis is also made. The different techniques to obtain movement data are discussed. Each technique is analyzed to find out the means of extracting the required posture data. The method to make it possible in real-time is described as well. An explanation of the working of the AviX software in storing information pertaining to the created tasks is given. The process of automatically modifying the task information in the software is described. A suitable experiment to test the entire procedure is </span><span style="background-color:initial">also created and explained. A study of the person’s posture during the experiment is discussed.</span></div> <div><span style="font-size:14px">The future possibilities with this method of obtaining movement data are also addressed and explained in this thesis.

To achieve a smart factory, it requires solving challenges from different domains. The research work focuses on identifying the challenges faced in the existing product development and provides recommendation of overcoming the challenges by implementing MBSE in practise [1]. The Thesis aims to investigate and provide recommendations about the model-based system engineering approach. The research work is divided into different phases, where, the first phase focused on understanding the model-based system engineering (MBSE) methodology and the barriers in the exiting product development process. The barriers identified played a major role in defining the use case in the later stage of the research work.</span></div> <div><span style="font-size:14px"><br /></span></div> <div><span style="font-size:14px">The second phase focuses on investigating the MBSE tool i.e., Capella. This phase deals with understanding the architecture behind the modelling techniques in Capella. ARCADIA is the system engineering method which utilizes models with a collaborative, evaluation and exploitation of the architecture. The different stages of the architecture are analysed, and the operations performed on each stage are documented. The third phase of the thesis work focuses on performing the product modelling in the MBSE tool. In order to perform the modelling, rear view door mirror subsystem has been chosen as a system of reference. The different model elements corresponding to the Door mirror components are modelled in Capella and the trace links are established. In order to implement the requirement integration </span><span style="background-color:initial">with the models, System Modeling Workbench (SMW) platform provided by Siemens is utilized. SMW interface is a replica of Capella with some additional integration features. The final phase is to verify MBSE and the model elements against the use cases. A list of product development activities is defined in the form of use cases and its implementations are discussed. The MBSE platform is validated against the use cases and the results are captured. </span></div> <div><span style="font-size:14px">The outcome of the research work is the Proof of concept in SMW for Teamcenter which attempts to eliminate the barriers identified in the existing PD processes. The thesis work concludes with the list of benefits upon implementing MBSE. It also provides certain guidelines and best practise methods to be followed upon implementation of MBSE in a project.</span></div></div> <div><br /></div> https://www.chalmers.se/en/departments/ims/calendar/Pages/Amir-Malakizadi.aspxhttps://www.chalmers.se/en/departments/ims/calendar/Pages/Amir-Malakizadi.aspxA physics-based framework for tool wear estimation in machining<p>On-line presentation</p><p>​​Amir Malakizadi, Researcher at Materials and manufacture​ IMS, will give an presentation to become &quot;oavlönad docent&quot;.</p><div><span style="font-weight:700">​<img src="/SiteCollectionImages/Institutioner/IMS/Profilbilder/Amir%20Malakizadi%20kalender.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /></span>​​<span style="background-color:initial">Amir M</span><span style="background-color:initial">alakizadi, </span><span style="background-color:initial">Researcher at Materials and manufacture</span><span style="background-color:initial">​ IMS</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span></span><a href="https://research.chalmers.se/en/person/?cid=amirma" target="_blank" style="outline:0px"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />More about Amir Malakizadi​</a><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="font-weight:700">Abstract</span><div><div>Machining is often regarded as the final step in most manufacturing processes, where the final dimensional tolerances are adjusted, and the functional surfaces are made. The machinists and process planners often need to take several factors into account to deliver the machined parts with the targeted requirements set by the designers. For example, tools with specific characteristics in terms of macro- and micro-geometries should be chosen along with an appropriate range of cutting conditions to achieve the best results for a given machining process like milling or turning. The challenge arises when the tool geometry constantly changes during the machining processes due to wear, resulting in poor machined surface quality and impermissible dimensional tolerances. Hence, it is of great importance to estimate wear progression on the cutting edge which allows for a timely tool change in production lines.</div> <div>Tool wear in machining is influenced by many parameters such as the cutting conditions, cooling-lubrication, machining type and clamping system, and most importantly the chemico-physical properties of the tool and workpiece materials. In general, varying any of these parameters leads to the changes in the tribological conditions on the tool surfaces, provoking different thermo-mechanical wear mechanisms such as abrasion, adhesion, diffusion-dissolution, oxidation and (discrete) plastic deformation. In addition, the tribological condition at the tool-chip-workpiece interfaces changes with wear evolution on the cutting edge during the machining process. A thorough understanding of the complex interactions between the tool and workpiece materials can enable us to develop more reliable and robust models for tool wear prediction in machining. This, however, demands a multidisciplinary approach which combines different modelling and experimental methods.</div> <div>In this lecture, I present a multidisciplinary approach where the results of tailored machining tests, multi-scale modelling and simulations and tool-workpiece material characterisation are combined for a better understanding of tool wear mechanisms in machining and for developing a robust wear modelling platform. I briefly discuss the wear behaviour of coated and uncoated tools when machining different grades of workpiece materials, including cast irons, steels and superalloys. A hybrid physics-based modelling platform is then presented which combines the Finite Element (FE) simulation results with thermodynamic estimations of the solubility of the tool constituents into the workpiece materials, allowing for robust tool wear estimations in machining. This modelling approach is shown to be very efficient in comparison with the widely used experimental tool life equations and the other alternative approaches available in literature.</div> <div><br
