Overview of the TREC 2011 Microblog Track
The Microblog track examines search tasks and evaluation methodologies for information seeking behaviors in microblogging environments such as Twitter. It was first introduced in 2011, addressing a real-time adhoc search task, whereby the user wishes to
Investigating the Application of Moving Target Defenses to Network Security
This paper presents a preliminary design for a moving-target defense (MTD) for computer networks to combat an attacker's asymmetric advantage. The MTD system reasons over a set of abstract models that capture the network's configuration and its operational
A Framework for Designing Cryptographic Key Management Systems
This Framework for Designing Cryptographic Key Management Systems (CKMS) contains topics that should be considered by a CKMS designer when developing a CKMS design specification. For each topic, there are one or more documentation requirements that need to
ACT-Touch Reference Manual, Working Draft
ACT-Touch is a set of manual motor request extensions for ACT-R 6 (Adaptive Control of Thought-Rational, hereafter, ACT-R) . These manual request extensions constitute theoretical claims predicting motor preparation and execution times for certain manual

On the Link Between Insertion Loss and Lower Bound of Efficiency
We investigate the effect of chamber loss on the recently developed 2-port antenna model and the associated method of determining antenna efficiency. The loss in the reverberation chamber was controlled using microwave absorbing foam creating four
ITL Publishes Guidance on Enterprise Patch Management Technologies
This ITL Bulletin summarizes a new ITL publication, NIST Special Publication 800-40 Revision 3, Guide to Enterprise Patch Management Technologies, which gives recommendations for organizations to improve the effectiveness and efficiency of their patch

Understanding impact of image quality on segmentation accuracy
We introduce a methodology for microscopy settings assessment and segmentation accuracy prediction based on image quality descriptors.
Performance Assessments of Android-powered Military Applications Operating on Tactical Handheld Devices
Transformative Apps (TransApps) is a DARPA-funded program whose goal is to develop a range of militarily-relevant software applications ("apps") to enhance the operational-effectiveness of military personnel on (and off) the battlefield. TransApps is also
The National Institute of Standards and Technology: NIST Contributions to Biometrics Technology
NIST has been at the forefront of information technology in its application to biometrics for almost 50 years. Early work revolved around developing hardware and software to perform automated analysis of fingerprint images and development of voice
Electrically-protected resonant exchange qubits in triple quantum dots
We present a modulated microwave approach for quantum computing with qubits comprising three spins in a triple quantum dot. This approach includes single- and two-qubit gates that are protected against low-frequency electrical noise, due to an operating
An Efficient Approach to Assessing the Risk of Zero-Day Vulnerabilities
Computer systems are vulnerable to both known and zero-day attacks. Although known attack patterns can be easily modeled, thus enabling the definition of suitable hardening strategies, handling zero-day vulnerabilities is inherently difficult due to their
An Efficient Approach to Assessing the Risk of Zero Day Vulnerabilities
Impact of Thermal Stability of Isolation Liner on the Electrical Characteristics of TSVs
This study is focused on understanding the effect of thermal cycling on the signal integrity characteristics of TSV isolation liner (SiO2). The use of radio frequency (RF) signals is found to be a good metrology tool for the detection of discontinuities in
Where in the Internet is Congestion?
Understanding distribution of congestion in the Internet is a long-standing problem. Using data from the SamKnows US broadband access network measurement study, commissioned by the FCC, we explore patterns of congestion distribution in DSL and cable
Non-Rigid and Partial 3D Model Retrieval Using Hybrid Shape Descriptor and Meta Similarity
Non-rigid and partial 3D model retrieval are two significant and challenging research directions in the field of 3D model retrieval. Little work has been done in proposing a hybrid shape descriptor that works for both retrieval scenarios, let alone the
Hybrid shape descriptor and meta similarity generation for non-rigid and partial 3D model retrieval
Non-rigid and partial 3D model retrieval are two significant and challenging research directions in the field of 3D model retrieval. Little work has been done in proposing a hybrid shape descriptor that works for both retrieval scenarios, let alone the
Dynamic light deflection in an active Raman-gain medium using a spatially inhomogeneous pump
We study optical wave deflection in a three-level active Raman gain medium using a spatially inhomogeneous pump field. Using the eikonal approximation, we derive an analytical expression for the deflection angle and demonstrate more than an order of
Computational Cognitive Modeling of Touch and Gesture on Mobile Multitouch Devices: Applications and Challenges for Existing Theory
As technology continues to evolve, so too must our modeling and simulation techniques. While formal engineering models of cognitive and perceptual-motor processes are well-developed and extensively validated in the traditional desktop computing environment
A Chosen IV Related Key Attack on Grain-128a
Due to the symmetric padding used in the stream cipher Grain v1 and Grain-128, it is possible to find Key-IV pairs that generate shifted keystreams efficiently. Based on this observation, Lee et al. presented a related-Key chosen IV attack on Grain v1 and
A Chosen IV Related Key Attack on Grain-128a
Shape Calculus for Shape Energies in Image Processing
Many image processing problems are naturally expressed as energy minimization or shape optimization problems, in which the free variable is a shape, such as a curve in 2d or a surface in 3d. Examples are image segmentation, multiview stereo reconstruction
Guide to Malware Incident Prevention and Handling for Desktops and Laptops
Malware, also known as malicious code, refers to a program that is covertly inserted into another program with the intent to destroy data, run destructive or intrusive programs, or otherwise compromise the confidentiality, integrity, or availability of the
Guide to Enterprise Patch Management Technologies
Patch management is the process for identifying, acquiring, installing, and verifying patches for products and systems. Patches correct security and functionality problems in software and firmware. There are several challenges that complicate patch
Computer Security Division 2012 Annual Report
Title III of the E-Government Act of 2002, entitled the Federal Information Security Management Act (FISMA) of 2002, requires NIST to prepare an annual public report on activities undertaken in the previous year, and planned for the coming year, to carry
