This paper specifies a global mobility management architecture and protocol procedure called GPMIP, which is based on Proxy Mobile IPv6. In GPMIP, mobility management is performed by the network entity rather than individual mobile nodes. The benefit is the elimination of the wireless link data delivery tunnel overhead between a mobile node and the access router. To compare with the well known ...

despite a renewed focus in the field of global health on strengthening health systems, inadequate attention has been directed to a key ingredient of high-performing health systems: management. we aimed to develop the argument that management – defined here as the process of achieving predetermined objectives through human, financial, and technical resources – is a cross-cutting function necessa...

the current limited focus on management in global health activities is highly problematic given the amounts of financial and human resources that are pouring into health system strengthening interventions and the complexity of clinical operations across settings. by ensuring that public health and healthcare practitioners in domestic and international settings receive management training in the...

Mobile Augmented Reality (AR) applications based on navigation frameworks try to promote interaction beyond the desktop by employing wearable sensors, which collect user’s position, orientation or diverse types of activities. Most navigation frameworks track location and heading of the user in the global coordinate frame using Global Positioning System (GPS) data. On the other hand, in the wear...

The current paper develops three different ways to measure the multi-period global cost efficiency for homogeneous networks of processes when the prices of exogenous inputs are known at all time periods. A multi-period network data envelopment analysis model is presented to measure the minimum cost of the network system based on the global production possibility set. We show that there is a rel...
