We propose a two-stage method for face hallucination. First, we generate facial components of the input image using CNNs. These components represent the basic facial structures. Second, we synthesize fine-grained facial structures from high resolution training images. The details of these structures are transferred into facial components for enhancement. Therefore, we generate facial components...

Efficiency aggregation and efficiency decomposition are two techniques used in modeling decision making units (DMUs) with two-stage network structures under network data envelopment analysis (DEA). Multiplicative efficiency decomposition (MED) is usually used in a very specialized two-stage structure when constant returns to scale (CRS) is assumed. MED-based network DEA retains the property of ...

The declustering problem is to allocate given data on parallel working storage devices in such a manner that typical requests find their data evenly distributed on the devices. Using deep results from discrepancy theory, we improve previous work of several authors concerning range queries to higher-dimensional data. We give a declustering scheme with an additive error of Od(log d−1 M) independe...

Research institutes, here defined as organizations involved in research and development but outside of the higher education sector and often in close cooperation with users, are found in most countries but not very well understood. This paper argues that institutes can be considered ‘‘hybrid organizations’’, caught in between dichotomous cultural spheres with differing values. To retain their h...

abstract background: rehabilitation of facial paralysis is one of the greatest challenges faced by reconstructive surgeons today. the traditional method for treatment of patients with facial palsy is the two-stage free gracilis flap which has a long latency period of between the two stages of surgery. methods: in this paper, we prospectively compared the results of the one-stage gracilis flap m...
