This document discusses various techniques for image retrieval, including text-based, content-based, and hybrid approaches. Content-based image retrieval (CBIR) extracts visual features like color, texture, shape from images and is able to retrieve similar images to a query image. CBIR systems segment images, extract features, search databases, and return results. CBIR has advantages over text-based retrieval but challenges remain around the semantic gap between low-level features and high-level concepts. The document also discusses evaluating retrieval performance and promising future research directions like reducing the semantic gap.
From InfoSec World 2009, Josh Abraham (of Rapid7) and I did a talk on owning the browser and why it's completely a broken concept... if you loved the presentation here are the slides!
The document introduces a co-branded magazine marketing tool for companies to communicate with and build loyalty among customers. For $21 per year, the magazine will produce 6 customized issues with company logos, photos, and messages delivered to top clients. Previous clients report increased sales, referrals, and loyalty through this personalized stay-in-touch program.
A recent presentation I did for a Second stage interview.
I found slightly challenging as Infrastructure testing a new industry for me but I thoroughly enjoyed every stage of the presentation from researching to presenting.
This document discusses simulating device driver faults using the KEDR framework. It begins by discussing the importance of fault tolerance for systems requiring high availability and reliability. It then provides background on related work in driver fault recovery. The document describes using KEDR to simulate faults like kmalloc failures and errors in copy_from_user and copy_to_user functions. It demonstrates configuring KEDR to inject faults and observe the effects on a sample kernel module. The document concludes by mentioning future work in improving system reliability during kernel module failures.
This document discusses the optimization of scaled silicon-germanium heterojunction bipolar transistors (SiGe HBTs) for key performance parameters affecting speed. It explores the effects of vertical and lateral scaling as well as germanium concentration variation on cutoff frequency, maximum oscillation frequency, and other metrics. Simulation results using ATLAS software show that while lateral scaling has less impact on cutoff frequency than vertical scaling, some degree of lateral scaling is needed to accompany vertical scaling. The maximum oscillation frequency depends on additional factors beyond cutoff frequency and is more adversely impacted by vertical scaling.
