- Automotive gears are facing stringent requirements regarding weight and functional surfaces, especially in view of the electric powertrain. To achieve these demands, powder metallurgy gears need to be finished using grinding, and in certain cases, mechano-chemical treatments. With regards to the latter, five different triboconditioning strategies based on vibratory tub finishing and/or centrifugal barrel finishing were considered and their effects on the surface integrity and friction behavior were investigated. Triboconditioning improved the surface roughness after grinding and resulted in higher compressive residual stresses. Additionally, microscopic observations of the surface topography were carried out. The lowest friction coefficients were observed for triboconditioning with a doped material (tribofilm) on the finished surface.

Collaboration processes A State of the Art
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The key objective of InPro is to define and support a new way of working with integrateddesign from a life cycle perspective, capturing client requirements and collaboration betweenstakeholders during the early design phase of a construction project. This phasestarts with the first client contact and ends with the delivery of a design proposal, withrecognisable functions, visualised for easy understanding and with a cost calculation tosupport the clients' go/no-go decision.The aim of Work Package 2 is to develop model-based and knowledge-based workingmethods for the Early Design phase. This will result in a systematic integration of lifecycledesign processes in new construction or renovation of buildings, taking into accountthe added values for society/citizens, clients/users, and the construction sector. ThisWork Package will also propose a framework for the collaboration process between involvedparties.The aim of Task 2.2 "Collaboration Processes" is to develop this framework for collaborationin the Early Design process, where all partners share information in a common OpenInformation Environment delivered by WP5 and add knowledge to the project. Thisframework of collaboration is a concept related to the needs of shared guidelines in orderto work efficiently together, generally defined in a contract. This framework will answerto the main question:How to create concurrent and iterative working processes with clear decisionmilestones?and includes other key questions:How to create functional working groups that represent different competenciesor backgrounds, including conflict resolution conceptsHow to to establish trustHow to balance between formal and informal communication channelsHow to communicate design changes in a virtual building model between concurrentlyworking design teams, e.g. by managing, categorising and highlightingdesign changesHow to reuse knowledgeIt also includes project and contractual issues management, progress monitoring, strategiesfor delegation of responsibility, methods for risk assessment and strategies for continuousimprovements based on measured Key Performance Indicators developed in Task1.3.

Partner engaged design : new challanges for workplace design
- 2002
-
Ingår i: Proceedings of PDC2002.

Konferensbidrag (refereegranskat)abstract
- The spatial organization of the workplace affects the work going on there. The technology used, changes the work practice. This paper describes a design process where different aspects of workplace design for project-based office work have been combined into one multi-stakeholder project, integrating the spatial aspects, the furniture, the information technology, and the IT-services that are connected to work. To have several different partners with different interests and competencies collaborating in a future oriented design process puts certain demands on the setup of the process and the tools being used. Taking a starting point in existing work practice, we have driven this project with techniques most often used for user-involvement. Scenario building played a crucial role in tying the process together. The concrete result is a completed concept proposal for an actual “office of the future” layout, which integrates advanced information technology and service solutions. The case shows that it is possible to reach innovative consensus-anchored results with the described design method.

Toward a Benchmarking Data Set Able to Evaluate Ligand- and Structure-based Virtual Screening Using Public HTS Data
- 2015
-
Ingår i: Journal of Chemical Information and Modeling. - : American Chemical Society (ACS). - 1549-9596 .- 1549-960X. ; 55:2, s. 343-353

Tidskriftsartikel (refereegranskat)abstract
- Virtual screening has the potential to accelerate and reduce costs of probe development and drug discovery. To develop and benchmark virtual screening methods, validation data sets are commonly used. Over the years, such data sets have been constructed to overcome the problems of analogue bias and artificial enrichment. With the rapid growth of public domain databases containing high-throughput screening data, such as the PubChem BioAssay database, there is an increased possibility to use such data for validation. In this study, we identify PubChem data sets suitable for validation of both structure- and ligand-based virtual screening methods. To achieve this, high-throughput screening data for which a crystal structure of the bioassay target was available in the PDB were identified. Thereafter, the data sets were inspected to identify structures and data suitable for use in validation studies. In this work, we present seven data sets (MMP13, DUSP3, PTPN22, EPHX2, CTDSP1, MAPK10, and CDK5) compiled using this method. In the seven data sets, the number of active compounds varies between 19 and 369 and the number of inactive compounds between 59 405 and 337 634. This gives a higher ratio of the number of inactive to active compounds than what is found in most benchmark data sets. We have also evaluated the screening performance using docking and 3D shape similarity with default settings. To characterize the data sets, we used physicochemical similarity and 2D fingerprint searches. We envision that these data sets can be a useful complement to current data sets used for method evaluation.

New certification system for enhanced fire safety of vehicles
- 2018
-
Ingår i: Proceedings of 7th Transport Research Arena TRA 2018.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- RISE has initiated and developed a certification scheme for the vehicle industry that will enable manufacturers, operators and service centres (workshops) to certify their fire risk mitigation process. The fire risk management required in the certification is a key safety element, used to identify and evaluate fire hazards. For best results, it is important that manufacturers, operators and service centres are equally dedicated to solve the fire problem. Vehicle fire investigations reveal that design, production, operation and maintenance can all be responsible, however, most important is to ensure that information and experiences from fire incidents and identified fire hazards are linked to relevant personnel, practices, manuals, and quality procedures. The certification cannot guarantee the elimination of vehicle fires, but can ensure that manufacturers, operators and service centres will operate at the front line of vehicle fire safety engineering.

Optimal Scheduling for Interference Mitigation by Range Information
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- This paper describes several algorithms for generating an optimal schedule for multiple access on a shared channel by utilizing range information in a fully connected network. We also provide detailed analysis for the proposed algorithms in terms of their complexity, convergence, and effect of non-idealities in the network. The performance of the proposed schemes are compared with non-aided methods to quantify the benefits of using the range information in the communication. We argue that the proposed techniques yield significant benefits as the number of nodes in the network increases. We provide simulation results in support of the claim. The proposed methods indicate that the throughput can be increased on average by 3-10 times for typical network configurations.
