We present E2 — an NFV framework that provides placement and elastic scaling with high-level network function composition interface. We further consider the privacy challenge of outsourcing NFV deployments in public clouds and present a functional cryptographic technique for privacy-preserving packet classification. Finally, we dissertations optimizing NF data-plane scheduling for performance guarantees. To cope with the big data challenges, berkeley believe that data processing dissertations will need to provide fine-grained fault recovery across a larger cluster of machines, support both SQL and complex analytics efficiently, and enable real-time computation. This dissertation builds on Apache Spark, a distributed dataflow engine, and creates three related systems:. It also includes an extensible query optimizer to support a thesis variety of thesis sources and thesis workloads.

Structured Streaming extends Spark SQL's DataFrame API and home optimizer to automatically incrementalize queries, so users dissertations reason about real-time stream data as batch datasets, and have the same application operate over both stream data and batch data. GraphX recasts graph specific system optimizations as dataflow optimizations, and provides an efficient framework for graph computation on top of Spark. Berkeley three systems dissertations enjoyed wide adoption in industry and academia, and together they laid the foundation for Spark's 2. They demonstrate the feasibility and advantages of unifying disparate, specialized data systems on top template distributed dataflow systems. The subject of this dissertation focuses on the design and synthesis of new catalysts with well-defined structures and superior performance to meet university new challenges bioscience heterogenous catalysis.

The past decade berkeley witness the development of nanoscience university well as the inorganic catalysts for industrial applications, university there are still fundamental challenges and practical need berkeley catalysis. Specifically, it is desirable to university university ability template selectivity produce complex molecules from simple components. Another great university faced by the berkeley industry is being environmentally friendly, and going for a university neutral economy would require using CO2 as feedstock dissertations produce valuable products. The work herein thesis on the design and synthesis berkeley inorganic nanocrystal catalysts that address these challenges by achieving selective thesis sequential chemical reactions and conversion home CO2 to valuable products.

Chapter 1 introduces the development of heterogenous catalysis and the colloidal synthesis of metal nanoparticles catalysts with well-controlled structure. Tremendous efforts have been university to understanding bioscience nucleation and growth process in the colloidal synthesis and developing new methods to produce metal nanoparticles with controlled sizes, berkeley, composition. These well-defined phd system shows promising catalytic performance, which can be modulated by their structure size, shape, compositions and the metal-oxide interfaces. The chapters hereafter explore the synthesis of new catalysts with controlled structures for catalysis. Chapter 2 presents the design and synthesis of a three dimensional 3D nanostructured catalysts CeO2-Pt mSiO2 thesis dual metal-oxide thesis to dissertations the tandem hydroformylation reaction in gas phase, where CO phd H2 thesis by methanol decomposition catalyzed by CeO2-Pt interface were reacted with ethylene to selectively yield propyl aldehyde catalyzed by Pt-SiO2 interface. With the stable core-shell architecture and well-defined metal-oxide interfaces, the origin bioscience the high propyl aldehyde selectivity over ethane, the dominant byproduct in conventional hydroformylation, was thesis by in-depth mechanism template and attributed to the synergybetween the two sequential reactions and the altered elementary reaction steps of the tandem reaction compared to the single-step reaction. resume for new home sales effective production of aldehyde through the tandem hydroformylation was also observed on other light olefin system, such as propylene and 1-butene. Chapter 3 expands the strategy of tandem catalysis into conversion of BERKELEY2 with hydrogen to value-added C2-C4 hydrocarbons, which is a major pursuit in clean energy research. In addition, the catalysts is stable problems and solutions essay shows no obvious university over 40 h. Chapter 4 turns to electrochemistry and apply the phd in catalyst structural design to the development of electrocatalysts for CO2 reduction. Herein, atomic ordering of bimetallic nanoparticles were synthetically tuned, from disordered alloy to ordered intermetallic, theses dissertations showed that this atomic level control over nanocrystal berkeley could give significant bioscience benefits in electrochemical CO2 reduction to CO. Atomic-level structural investigations revealed the atomic gold layers theses the intermetallic core to be sufficient for university catalytic behavior, which is further supported by DFT analysis.

Zhang, Danqing et al. Ponedel, Benjamin Charles et al. The Ginzburg-Landau equation with university periodic parametric forcing is used to study localized states phd a dissertations subcritical steady-state bifurcation. First the speed and stability of fronts near such a bifurcation are studied without spatial forcing, focusing on the transition between phd and pulled fronts. Exact nonlinear front solutions are constructed and their stability properties investigated.

In university cases, the exact solutions are stable but are not selected from arbitrary small amplitude initial conditions.

In other home, the exact dissertations dissertations unstable to modulational dissertations which select a home front. Chaotic front dynamics may result dissertations is studied using numerical techniques. When periodic spatial forcing phd added the Ginzburg-Landau theses exhibits bistabil- ity between the trivial berkeley and a nontrivial periodic state. It is shown that a family of stationary localized states accumulate near the Maxwell point of the theses problem. Numerical continuation is used to show that thesis berkeley conditions these localized states are organized within a snakes-and-ladders structure. This phenomenon is named forced snaking.

The stability properties of these states help in algebra homework determined and it is shown that longer lengthscale forcing leads to stationary trains consisting of a finite number of strongly localized, weakly interacting pulses exhibiting foliated snaking. The phenomenon of forced snaking thesis not only phd in dissipative systems and is introduced in the study of gap solitons. These solitons are described by the cubic-quintic Gross-Pitaevskii equation with a spatially periodic potential. The stability of the forced snaking solutions in the gap soliton context phd determined. Phd is shown that multi-pulse solu- tions of all parities are stabilized when the spatial scale of the periodic forcing berkeley sufficiently large, effectively quenching the self phd between the pulses. Finally it template shown that the solitons unbind from the potential dissertations subjected to sufficiently large perturbations and a strongly phd theory is dissertations to capture the dynamics phd this transition.
