The synthesis and organization of functional nanostructures using self-assembly processes embodies a critical challenge for nanoand meso-science, as twoand three-dimensional (2D and 3D) spontaneous arrangement of nanoscale structural units or building blocks can produce ordered ensembles that exhibit collective functionality at reduced cost with greater efficiency [1,2]. Generating arrays of na...

Internet and information technologies have changed the way people interact and make business all over the world. Unfortunately, this is not completely true in the sense that the fast progress fostered by more dynamic economies has in fact been contributing to widening the so-called digital divide between rich and poor. This is a particularly true for small and medium enterprises in remote commu...

The impact of global slowdown and busted Internet ventures may have led to a rationalized view of the role IT play in businesses. But that has not stopped global 2000 businesses from investing for collaborating with partners and customers. IT has drastically reduced cost of collaboration in the last 20 years. One consequent change in the business environment is the delineation in emphasis on po...

This paper describes a fully decentralized nonlinear control law for spinning tethered formation flight, based on exploiting geometric symmetries to reduce the original nonlinear dynamics into simpler stable dynamics. Motivated by oscillation synchronization inbiological systems,weuse contraction theory to prove that a control law stabilizing a single-tethered spacecraft can also stabilize arbi...

In cloud-computing systems, network-bandwidth guarantees have been shown to improve predictability of application performance and cost [1, 28]. Most previous work on cloud-bandwidth guarantees has assumed that cloud tenants know what bandwidth guarantees they want [1, 17]. However, as we show in this work, application bandwidth demands can be complex and time-varying, and many tenants might lac...

Many roads in the United States have approached the end of their design and/or service lives. In a recent report published by the American Society of Civil Engineers (ASCE), 42% of highways in the United States are congested and cost the economy about $100 billion in wasted time and extra fuel consumption. Due to the poor condition of the national highway network, it has been given a grade “D” ...

In phenomenological applications the time evolution of subsystems immersed in an external environment are sometimes described by Markovian semigroups of Redfield type that result non-positive: the appearence of negative probabilities is avoided by restricting the admissible initial conditions to those states that remain positive under the action of the dynamics. We show that this often adopted ...

Interest in, and use of, remote laboratories has been rapidly growing. These laboratories provide remote access, via the internet, to real laboratory equipment. Under appropriate circumstances they can support or even replace traditional (proximal) laboratories, provide improved access at reduced cost, and encourage inter-institutional sharing of expensive resources. Most attention to date has ...

The Shortened Dental Arch (SDA) concept introduced as early as 1981 by Kayser and was accepted by a great majority of dentists but not widely practiced. The SDA comprising anterior and premolar teeth in general fulfill the requirements of a functional dentition. Patients’ needs and demands vary much and should be individually assessed but the SDA concept deserves to be included in all treatment...

Using an exact reformulation of the classical surface water wave problem due to Ablowitz, Fokas and Musslimani, we investigate the instabilities of one-dimensional stationary periodic waves, with respect to transverse perturbations. Such perturbations have trigonometric dependence on the transverse variable, and are bounded (typically quasi periodic) in the longitudinal direction. Using the new...
