When a delay occurs in a project, there are basically two options: prescribing overtime work and injecting additional resources, in order to meet the project schedule of certain activities. This paper uses economic analysis to demonstrate that a decision maker will select the most suitable alternative by considering productivity losses in overtime work and the relative unit costs between differ...

The MiCRAM project has been developing detailed neural models of the inferior colliculus (IC) as the basis for understanding the neural networks that underlie early auditory processing at that level. The initial phase of this project has been to develop biologically plausible models of the physiologically distinct cell types of the IC. This has led to the recognition that some of the gross beha...

this article proposes a direct method for solving three types of integral equations with time delay. by using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. numerical examples shows that the proposed scheme have a suitable degree of accuracy.

One of the major characteristics of the capital budgeting process is the delay existing between the investment decision and its implementation. This paper analyses investment decisions under uncertainty with implementation delay in a unified analytical framework. We provide closed-form solutions relating the value of the investment opportunity and the optimal investment threshold to the size of...

INTRODUCTION A 20-month quality improvement project was undertaken in order to improve the patient admission process at a 350-bed French public psychiatric hospital. In addition to improving the quality of patient admissions, the project was expected to increase the expertise of quality improvement team members. METHODS The project team consisted of two physicians, three heads of nursing, one...

OBJECTIVE To analyze the impact of reperfusion by either primary percutaneous coronary intervention (PPCI) or fibrinolysis, and mortality rates of a pre-hospital fast-track network for treating patients with ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS A pre-hospital network for STEMI patients, designated the Green Lane for Acute Myocardial Infarction (GL-AMI), has been imp...

Using their biological sonar, bats estimate distance to avoid obstacles and capture moving prey. The primary distance cue is the delay between the bat's emitted echolocation pulse and the return of an echo. The mustached bat's auditory midbrain (inferior colliculus, IC) is crucial to the analysis of pulse-echo delay. IC neurons are selective for certain delays between frequency modulated (FM) e...

BACKGROUND Early childhood dental caries (dental cavities) is an infectious process. The development of oral problems during cancer care results in pain, fever, and delay in treatment. 
. OBJECTIVES The objective of this project was to integrate preventive oral care into pediatric oncology care. 
. METHODS This project consisted of an educational program for pediatric oncology providers who...

This paper gives an overview of the French collaborative project SAMU1, Advanced Services by Mastering UMTS, dedicated to develop enhanced services for users in a car. For that purpose, complementary research domains have been investigated such as radio resource management, IP over UMTS and the use of software agents. While field trials were planned in the project to validate the outputs of the...

This paper studies situations in which a project consisting of several activities is not executed as planned. It is divided into three parts. The first part analyzes the case where the activities may be delayed, this possibly induces a delay on the project as a whole with additional costs. Associated delayed project games are defined and are shown to have a nonempty core. The second part consid...
