My project is to experiment with the state of the art, as well as current shortcomings, in Big data integration and analysis. We will build a search engine to integrate Public Linked Data into Patent Data to provide more sematic contexts and values to each patent. We build the interface and connection to retrieve the traditional data from the front-end website.

We investigate the relationship between visual elements and statistical quantities in cities.Although certain city statistics like the presence of trees and graffiti have a natural connection to visual elements, more abstract statistical quantities such as crime rates and housing prices relate to visual content in a less intuitive way. We show that there is a strong connection between visual elements and these statistics and that this relationship is general enough to predict these statistics in new cities.

TCP’s slow-start was designed to prevent hosts from sending more data into the network than it is capable of transmitting. A key component of slow-start is the initial congestion window or init_cwnd. Today, it is set to at most four segments or roughly 4KB of data. As a result, every short-lived TCP connection (henceforth “short flow”) suffers a performance hit when it comes to throughput (and by extension, latency), for it does not last long enough to achieve its fair share of the network bandwidth. A commonly proposed technique to lower latency for these short connections is to increase the size of TCP’s initial congestion window. However, simply increasing the init_cwnd does not protect short flows from packet loss, which affects them more adversely than it affects long-lived TCP connections. In this paper, we introduce the concept of a super-packet to augment the proposal of increasing the initial congestion window. A super-packet is a network abstraction consisting of a finite number of consecutive packets. These packets form a logical unit on which a router makes a forwarding decision. We will present an efficient algorithm for super-packet admission in routers, conduct a security analysis of the algorithm, discuss deployment opportunities, and analyze the benefits of using super-packets.

Large-scale data analytics frameworks are shifting towards shorter task durations and larger degrees of parallelism to provide low latency. However, scheduling highly parallel jobs that complete in hundreds of milliseconds poses a major challenge for cluster schedulers, which will need to place millions of tasks per second on appropriate nodes while offering millisecond-level latency and high availability. We demonstrate that a decentralized, randomized sampling approach provides near-optimal performance while avoiding the throughput and availability limitations of a centralized design.We implement and deploy our scheduler, Sparrow, on a real cluster and demonstrate that Sparrow performs within 14% of an ideal scheduler.

An optimization-based method for identifying the speed profile of a moving surface from image data is studied.If the dynamic surface motion is modeled by a level set equation, the identification problem can be formulated as an optimization problem constrained with the level set equation whose (viscosity) solution, in general, has kinks. The non-differentiable solution prevents us from having a bounded gradient of the cost function of the optimization problem. To overcome this difficulty, we develop a novel identification approach using a regularized level set equation.

This work presents in detail the design, fabrication and testing of the transparent μECoG arrays including verification of impedance, transparency, and electrical properties. These arrays have the smallest electrodes to date of any μECoG array, transparent or otherwise, enabling higher spatial-temporal resolution than previous devices. This work also extends previous work by plating the ITO electrodes with the transparent conductive polymer PEDOT [27] in order to improve electrochemical impedance properties and characterizing the results. The intent of the author is that this work can function as detailed instruction manual for designing, manufacturing, and testing μECoG devices made with transparent electrode technology. The work ends by describing next steps for utilizing the transparent μECoG arrays in research on the origin of μECoG signals in the cortex, combining optogenetics with holographically patterned light sources.

We introduce and discuss new user interface issues raised by the advent of gesture recognitionenabled mobile devices. Compared to traditional hand gestures on touch-screens of mobile devices, the effectiveness of gesture recognition on mobile devices depends on their screen sizes, the distance between the user and the device, and how the user holds the device. Due to these user interface issues, software developers who would like to apply gesture recognition to their applications should redesign their user interfaces different from typical mobile applications. To effectively visualize feedback of a physical therapy applicatio for mKinect, the purpose of which is to bring the users Kinect experience onto their smartphones, we present a novel approach of visual feedback for a gesture recognition-enabled mobile devices.

We present a novel algorithm to acquire and analyzerich 3D geometric features in single urban images. Traditional representation of 3D structures via local image features lack global geometric information to provide high-quality image correspondence and 3D models. The new approach utilizes the low-rank representation technique to seek a new class of invariant features based on minimizing the matrix rank of image textures, which are more holistic with respect to global geometric information, invariant tocamera distortion, and robust to pixel corruption.

Historically, our society requires computational memory media to support the development of our civilization. It is likely that our society will keep demanding larger capacity memory. However, conventional memory technologies are facing many challenges such as difficulties of miniaturization and guarantee of good reliability. For this reason, alternate memory device designs are proposed to overcome the conventional memory device technologies.
