Bhulai, Sandjai (author), Li, P (author), van Essen, J.T. (author)Taxis are an essential component of the transportation system in most urban centers. The ability to optimize the efficiency of routing represents an opportunity to increase revenues for taxi drivers. The vacant taxis cruising on the roads are not only wasting fuel consumption, the time of a taxi driver, and create unnecessary carbon emissions...conference paper 2017

Li, P. (author), Jiang, L.J. (author)A hybrid electromagnetics (EM)-circuit simulation method employing the discontinuous Galerkin finite element time domain method (DGFETD) is developed to model single lumped port networks comprised of both linear and non-linear elements. The whole computational domain is split into two subsystems. One is the EM subsystem that is analyzed by the...conference paper 2013

Li, P. (author), Oosterling, J.A.J. (author), Hoogstrate, A.M. (author), Langen, H.H. (author), Munnig Schmidt, R.H. (author)In experiments of machining hardened tool steels (such as AISI H11, H13, and D2, up to 56 HRC) by commercial Ø 0.5 mm square endmills, it is observed that the tested micro endmills showed severe wear at an early stage of the process due to chipping off around cutting edge corners, resulting in unsatisfactory tool life and product appearance ...journal article 2011

Li, P. (author), Zdebski, D. (author), Langen, H.H. (author), Hoogstrate, A.M. (author), Oosterling, J.A.J. (author), Munnig Schmidt, R.H. (author), Allen, D.M. (author)Micro features with high aspect ratios are one of the commonly encountered geometries found in micro products. In the literature, these structures are often used in demonstrator products machined by a micromilling process. In this paper, the challenges in micromilling thin ribs ith high aspect ratios have been studied. Due to the scaling effect,...journal article 2010

Li, P. (author)Miniaturized parts are increasingly demanded in different fields like medical, transportation, environmental, and communication industries. In order to manufacture these parts in an economical way, mass replication methods, such as micro injection molding, have to be applied. Currently, Electro Discharge Machining (EDM) process is mainly used to...doctoral thesis 2009
