  • Nagendra Krishnapura, Indian Institute of Technology, Madras
An all-pass filter architecture that can be generalized to high orders, and can be realized using active circuits, is proposed. Using this, a compact true-time-delay element with a widely tunable delay and a large delay-bandwidth product is demonstrated. This is useful for beamforming and equalization in the lower GHz range where the use of LC or transmission line based solutions to realize large...

Jacobs Design Conversations: Alan Eustace

Solid State Technology and Devices Seminar

521 Hogan Room Cory Hall
  • Farnaz Niroui, University of California, Berkeley
Strong surface adhesive forces between neighboring surfaces in nanoelectromechanical (NEM) switches have presented a continuous challenge to the fabrication and operation of these devices. Stiction, which becomes ever more prominent with switch miniaturization, leads to hysteresis in switching. This results in increased active power consumption, limiting the energy efficiency of the device....

Getting the Best of Nanomaterials: Intercalated Graphene/Quantum Dot Hybrid Photodetector

60 Evans Hall
  • Prof. Oscar Vazquez Mena, UC San Diego, NanoEngineering
Recently, hybrid graphene quantum dot (Gr/QD) systems have emerged as high responsivity photodetectors, taking advantage of the high charge carrier mobility of graphene and the high light absorption of PbS quantum dots. However the performance of this hybrid system is still limited by the charge carrier diffusion length of quantum dots, which remains the main bottle neck for quantum dot based...

Double Quantum Dot Nanocrystal Synthesis and Applications

60 Evans Hall
  • Prof. Dan Oron, Weizmann Institute, Applied Physics
Colloidal semiconductor nanocrystals have evolved in the past decades from a topic of pure scientific interest to a technological one. This has been driven by dramatic advances in the ability to fabricate controlled complex structures via wet chemistry methods. Today, exquisite control can be exerted on the detailed structure and energy landscape within colloidal nanoparticles, leading to new...

Dissertation Talk: Machine Learning for Resource Management in the Datacenter and the Cloud

465H Soda Hall
  • Neeraja J. Yadwadkar, UC Berkeley
In this talk, I argue that advancements in machine learning can be leveraged to manage and optimize contemporary distributed systems by deriving actionable insights from performance data. To realize this vision of model-based resource management, we show how to deal with the key challenges of data-driven models: uncertainty in predictions, cost of training, and cost of updating the models.
