BACKGROUND The purpose of this study was to identify factors related to the unexpected vault in V4c implantable collamer lens (ICL; STAAR Surgical) implantation. METHODS V4c ICLs were implanted in 43 eyes of 43 patients for the correction of myopia. The implanted V4c ICL sizes were determined individually with our previous V4 ICL sizing nomogram based on the sulcus-to-sulcus diameter (STS), a...

Even with the rapid changes in the level of complexity and the uncertainty of the environment in which Belgian sea fisheries operate, fisheries management in Belgium is still mainly based on restrictive policy instruments founded in the biological approach of fisheries management science. Since they will continue to play an important role, this paper evaluated changes in three restrictive polic...

Abstract In the classic Vehicle Routing Problem (VRP) a fleet of of vehicles has to visit a set of customers while minimising the operations’ costs. We study a rich variant of the VRP featuring split deliveries, an heterogeneous fleet, and vehiclecommodity incompatibility constraints. Our goal is twofold: define the cheapest routing and the most adequate fleet. To do so, we split the problem in...

This paper presents a model to coordinate the pricing and fleet management decisions of a freight carrier. We consider a setting where the loads faced by the carrier over a certain time horizon are deterministic functions of the prices. We want to find what prices the carrier should charge so that its pricing and fleet management decisions jointly maximize the profits. Our solution approach is ...

This paper describes the current evolutions and perspectives of the FTS real-time executive as the colonne vertébrale of the Ircam “Real-Time Platform” project, which is a software oriented continuation of the “Ircam Musical Workstation” project.

One of the most important subjects in nuclear power plants is sizing of flaws which are detected during InService Inspection (ISI), since reliability of flaw sizing is very important to estimate the life of the structure or pressure equipment. The most difficult matter for applying the flaw sizing techniques mentioned above is how to identify the flaw tip signal, especially in the case of natur...

Multiple virtual machine (VM) workloads are increasingly common, given the growth of managed enterprise application systems and consolidated virtual servers. Until now, there has been no principled approach to partitioning memory resource between multiple co-located VMs. In this paper, we develop a general framework for multi-VM heap sizing, based on the principle of utility maximization from m...

This paper reviews the development of a root mean squared error (RMS) flaw sizing criterion. The effect of using an RMS error criterion for the sizing performance of the PISC II [1-3] inspection teams is investigated. A crucial part of establishing an RMS error sizing criterion is the decomposition of the components in the RMS error into the sum of the squares of the mean error, the standard er...

The majority of actors in the Norwegian fisheries consider recruitment of fishers to be the main future challenge for the Norwegian fishing fleet. As fleet recruitment is a highly politicized field, the problem of how to mitigate the recruitment problem is a subject of heavy debate. Some argue that recruitment problems are caused by low fleet profitability, while others argue that recruitment p...

This thesis aims to elucidate real option thinking and real option valuation techniques for innovative technology investment. Treating the fuel cell R&D investment as a real option for General Motor's light passenger vehicle fleet, the thesis presents a 3-step approach to value the R&D and its influence on the fleet value, in which the uncertainties and managerial flexibility are proactively ac...
