We consider 6-dimensional nearly Kähler manifolds M and prove that any totally geodesic hypersurface N of M is a Sasaki-Einstein manifold, and so it has a hypo structure in the sense of [8]. We show that such a hypo structure defines a nearly Kähler structure on N × R, and a compact nearly Kähler structure with conical singularities on N 5 × S 1 when N is compact. Moreover, an extension of the ...

Tourists want to tell other people about their journeys and adventures. This is often done via social networks and digital photos. But what if one could tell other people about a great tour by sharing the tour itself with others than just photos or short messages?. In this paper, we present an intuitive authoring tool for gamebased city tours and a rendering app for these tours on iOS. This way...

A discrete-time decentralized routing problem in a service system consisting of two service stations and two controllers is investigated. Each controller is affiliated with one station. Each station has an infinite size buffer. Exogenous customer arrivals at each station occur with rate λ. Service times at each station have rate μ. At any time, a controller can route one of the customers waitin...

Proposed in this paper is a relative complexity metric deduced from the principles of cross-entropy associated with a complex system. Further indicated is the use of such a metric in decision-theoretic applications relevant to a complex system. As an example, the proposed method is applied to modern cellular phone systems in facilitating the so-called hard handoff effort by which, a mobile unit...

The prevailing labor market models assume that minimum wages do not affect the labor supply schedule. We challenge this view in this paper by showing experimentally that minimum wages have significant and lasting effects on subjects’ reservation wages. The temporary introduction of a minimum wage leads to a rise in subjects’ reservation wages which persists even after the minimum wage has been ...

The concept of hypo-Euclidean norm for an n−tuple of vectors in inner product spaces is introduced. Its fundamental properties are established. Upper bounds via the BoasBellman [1]-[3] and Bombieri [2] type inequalities are provided. Applications for n−tuples of bounded linear operators defined on Hilbert spaces are also given.
