We propose to develop a new system, SARAN, to transparently, and efficiently, instrument Android applications. SARAN supports the transparent instrumentation of entire Android APKs (i.e., both DEX bytecode and native libraries). DEX bytecode is instrumented using a static binary decompilation that lifts the bytecode into an intermediate representation that facilitates program analysis and transfor ...

This proposal aims to provide a general framework for cross-layer instrumentation of mobile applications for Android platforms. Our approach uses static and dynamic binary analysis to identify known functional code blocks and libraries in mobile applicat...

Vacuum Electronic Devices (VEDs) represent the most compact and efficient means of generating high power RF available today. Unfortunately, the legacy electronics required to operate these VEDs remain large, heavy, and often unreliable. The transition to...

Despite several commercial deployments and successes, current recommender systems require designers to hand tune features describing the data, which then remain static for months or years. Since modern applications increasingly rely on streaming data, the next generation of defense, intelligence and commercial recommender systems would need to automate the continuous updating and tuning of feature ...

This SBIR proposal is for development of a second generation Spacecraft Identification Device (a.k.a. sticker) for the Space Object Automated Reporting System (SOARS).SOARS combines space-object beacons, automated, low-cost, ground collecti...

The challenge of improving maternal healthcare outcomes in Kenya requires an approach that comprehensively acquires and represents knowledge related to the public healthcare landscape, placing observed data and outcomes in context to determine why women are not receiving the care that is available to them. Without the ability to structure and connect various data, capabilities are limited in their ...

U.S. national security interests increasingly rely on strategies and tactics that require a deep and accurate understanding of human behavior across the full range of contexts and cultures found across the globe. Unfortunately, the behavioral and social sciences are not well poised to produce research capable of advancing our understanding at a global level.This research is often limited by labora ...

During Phase II we propose to develop miniaturized mmW seeker antenna technologies to enable radar-guided medium-caliber projectiles with course-correction capability. The overall program goal is to mature our seeker antenna concepts through prototype hardware demonstrations. Concepts will be demonstrated on platforms less than one inch in diameter. Gun-launch survivability of the seeker antennas ...

SI2 Technologies, Inc. (SI2) proposes to design and develop conformal end-fire seeker antenna systems to enable guided medium caliber projectiles. We will leverage our validated Phase I antenna and surface treatment designs to refine and optimize a form-factor antenna system and manufacturing plan for targeted munitions platforms. The proposed antenna is conformal, extremely low profile and afford ...

Evaluating security mechanisms is a difficult and manual process. To effectively compare different techniques, security analysts use synthetic benchmarks that are typically comprised of simple test cases or a combination of known vulnerabilities in an attempt to provide coverage for different classes of attacks. As such, security mechanisms adapt their techniques to guarantee good coverage for the ...
