This work presents a convenient and non-contact acoustic sensing approach for measuring ground vibration. This approach, which uses an instantaneous dynamic tire pressure sensor (DTPS), possesses the capability to replace the accelerometer or directional microphone currently being used for inspecting pavement conditions. By measuring dynamic pressure changes inside the tire, ground vibration ca...

Tires are a key sub-system of vehicles that have a big responsibility for comfort, fuel consumption and traffic safety. However, current tires are just passive rubber elements which do not contribute actively to improve the driving experience or vehicle safety. The lack of information from the tire during driving gives cause for developing an intelligent tire. Therefore, the aim of the intellig...

Large amounts of rubber particles are dispersed into the environment due to tire wear. The rubber contains a wide range of chemicals, including several of environmental concern. The purpose of this thesis, which is based on six papers [I–VI], was to assess the ecotoxicological hazard and risk associated with tire wear particles, with a main focus on the aquatic environment. A method was develop...

Lean health care is one of new managing approaches putting the patient at the core of each change. Lean construction is based on visualization for understanding and prioritizing imporvments. By using only visualization techniques, so much important information could be missed. In order to prioritize and select improvements, it’s essential to integrate new analysis tools to achieve a good unders...

Purpose – The purpose of this paper is to explore if six sigma and lean are new methods, or if they are repackaged versions of previously popular methods – total quality management (TQM) and just-in-time (JIT). Design/methodology/approach – The study is based on a critical comparison of lean with JIT and six sigma with TQM, a study of the measure of the publication frequency – the number of aca...

Six Sigma is a systematic improvement method, management approach designed to continuously improve corporate business processes and achieve customer requirement. This paper presents case study conducted at cell phone manufacturing company that intended use the DMAIC method carry out structured projects with fewer defective units generated by hot press in process. In this process, Boss cracking ...
