The ongoing quest for the tight integration of network operation and service provisioning initiated with introduction 5G often clashes capacity current architectures to provide means such integration. Owing traditional design mobile networks, which barely required a interaction, elements offer capabilities their continuous optimization just within domain (eg, access, or core), allowing “silo-st...

Open loop dynamic stability is a major feature of operability. An optimization approach for open loop stable process design is presented. It is based on Lyapunov’s stability theory and formulated as an eigenvalue optimization problem. The resultant non-linear semi-definite programming problem is reformulated into an interior-point / logarithmic-barriertransformation programming problem. The pro...

The accurate modeling of the electronic structure of atoms and molecules involves computationally intensive tensor contractions over large multidimensional arrays. Efficient computation of these contractions usually requires the generation of temporary intermediate arrays. These intermediates could be extremely large, requiring their storage on disk. However, the intermediates can often be gene...

Loop optimizations such as loop unrolling, unfolding and invariant code motion have long been used in a wide variety of compilers to improve the running time of applications. In this paper we present a series of experimental results detailing the effect these techniques have on the running time of Java applications following ahead of time optimization. We also detail the optimization tools and ...

( ) The simulation-based optimization framework Sim-Opt uses a twin-loop computational architecture, which combines mathematical programming and discrete e®ent simulation, to address this problem. This article extends our earlier work to present methods ( for integrating information from the inner loop Sim-Opt time lines, reacti®e adjust) ( ) ment and using it in the outer risk-control loop Sto...

We present results of the restoration of all crystallographically available intra- and extracellular loops of four G-protein-coupled receptors (GPCRs): bovine rhodopsin (bRh), the turkey β-1 adrenergic receptor (β1Ar), and the human β-2 adrenergic (β2Ar) and A2A adenosine (A2Ar) receptors. We use our Protein Local Optimization Program (PLOP), which samples conformational space from first princi...

The problem of generating the trajectory for high rise/ high speed elevators is investigated in this paper. Several approaches are used: open loop optimal control, closed loop optimal control and optimization algorithms. Each approach is accompanied by numerical simulations.

Emerging micro-processors introduce unprecedented parallel computing capabilities and deeper memory hierarchies, increasing the importance of loop transformations in optimizing compilers. Because compiler heuristics rely on simplistic performance models, and because they are bound to a limited set of transformations sequences, they only uncover a fraction of the peak performance on typical benc...

optimization is an important methodology for activities in planning and design. the transportation designers are able to introduce better projects when they can save time and cost of travel for project by optimization methods. most of the optimization problems in engineering are more complicated than they can be solved by custom optimization methods. the most common and available methods are he...
