We examine the use of in-cylinder measurements for engine control, with emphasis on emissions control during cold start. First, the cold start emissions control problem is described. An overview of previous research in the area of in-cylinder measurements for control is presented, including sensors for pressure and other quantities. Next, analysis of cylinder pressure is described. Lastly, a cold-
This paper describes the design of a least restrictive, safe hybrid control scheme for a manufacturing transport system transporting fragile objects from a production unit to a stamping/packaging station. The control scheme consists of several control modes. One control mode handles trajectory following using time-optimal control, the other control modes are safety related and are engaged in a lea
We analyze the effects of the increase in China’s import competition on Mexican domestic and international migration. We exploit the variation in exposure to competition from China, following its accession to the WTO in 2001, across Mexican municipalities and estimate the effect of international competition on the individual decision to migrate. Controlling for individual and municipality features
This paper proposes a method for structural enhancement of a 3D sampled curve. The curve is assumed to be organized, but corrupted with low frequency noise. The proposed method approaches the notion of curve reconstruction in a novel way, where information about the structure in a scanned surface is used to reconstruct the curve. Principal Component Analysis is carried out on successive neighborho
This article examines two issues located at the core of thePalestinian struggle: Jerusalem and the refugee camps. I aim totrace the forced encounter staged at these two crucial sites ofcontestation, while looking at the collisions/interactions that occurbetween them, and the types of geographies that are producedwithin an experience of abandonment. This is done by exploringhow the colonized re-pro
Lefebvre’s ‘right to the city’ was an expression of a new politics of citizenship,residency and above all the right to urban life. We thus build our argument inthis paper on the Lefebvre concept and through the case study of Kufr Aqab, thenorthernmost neighbourhood of the occupied city of Jerusalem. In order tosystematically displace Palestinian Jerusalemites and to achieve the Judaisationof Jerus
Recently the 19th century as a formative period of both states and the state system has received more attention by IR scholars, historical sociologists, and historians. A highly generalized argument that this diverse literature has in common is that the state became more state-like, and the international system denser, and therefore more system-like, in the 19th century. The modern world has its r
The treatment of Parkinson's disease (PD) has for over 50 years relied on dopaminergic therapies that are highly effective especially in the early years of the condition, but ultimately are limited by the development of side effects that relate to the nonphysiological stimulation of dopamine receptors including in nonstriatal areas. Targeted regenerative therapies designed to restore specifically
Coupled one-dimensional (1D) sewer and two-dimensional (2D) overland flow hydrodynamic models were constructed to evaluate the flood mitigation efficiency of a renowned blue-green stormwater retrofit, i.e. Augustenborg, in Malmö, Sweden. Simulation results showed that the blue-green stormwater systems were effective in controlling local surface flooding in inner-city catchments, having reduced the
In the study presented in this paper a single-cylinder Scania D12 diesel engine has been converted to work as a pneumatic hybrid. During pneumatic hybrid operation the engine can be used as a 2-stroke compressor for generation of compressed air during vehicle deceleration and during vehicle acceleration the engine can be operated as an air-motor driven by the previously stored pressurized air.The
