Weather Research Requirements To Improve Space Launch From Cape Canaveral Air Force Station And Nasa Kennedy Space Center, William P. Roeder, Lisa L. Huddleston, William H. Bauman Iii, Kelly B. Doser

Space Traffic Management Conference

Weather has a large affect on operations at Cape Canaveral Air Force Station (CCAFS) and NASA Kennedy Space Center (KSC). Weather is the leading source of scrubs and delays to space launch from CCAFS/KSC. Weather has an even larger impact on ground processing as space launch vehicles and payloads are prepared in the months before space launch. Many of those operations are very sensitive to weather. In addition, the weather in Florida is notoriously difficult to predict, especially during the summer when rapid deep convection can occur in minutes. Finally, the weather can be extremely subtle in this area during …

Improving Airplane Touchdown Control By Utilizing The Adverse Elevator Effect, Nihad E. Daidzic Ph.D., Sc.D.

International Journal of Aviation, Aeronautics, and Aerospace

The main objective of this original research article is to understand the short-term dynamic behavior of the transport-category airplane during landing flare elevator control application. Increasing the pitch angle to arrest the sink rate, the elevator will have to produce negative lift to rotate the airplane’s nose upward. This has an immediate adverse effect of initially accelerating airplane downward. A mathematical model of landing flare based on the flat-Earth longitudinal dynamics of rigid airplane was developed which is realistic only on very short time-scales as pitch stiffness and damping were neglected. Pilot control scenarios using impulse and step elevator pull-up …

Variable Viscosity Condition In The Modeling Of A Slider Bearing, Kedar Nath Uprety, S.C. Mancas

Publications

To reduce tear and wear of machinery lubrication is essential. Lubricants form a layer between two surfaces preventing direct contact and reduce friction between moving parts and hence reduce wear. In this short letter the lubrication of two slider bearings with parallel and nonparallel is studied. First, we show that bearings with parallel plates cannot support any load. For bearings with nonparallel plates we are interested on how constant and temperature dependent viscosity affects the properties of the bearings. Also, a critical temperature for which the bearings would fail due to excess in temperature is found for both latter cases. …

Investigative Techniques Of N-Way Vendor Agreement And Network Analysis Demonstrated With Fake Antivirus, Gary Warner, Mike Nagy, Kyle Jones, Kevin Mitchem

Annual ADFSL Conference on Digital Forensics, Security and Law

Fake AntiVirus (FakeAV) malware experienced a resurgence in the fall of 2013 after falling out of favor after several high profile arrests. FakeAV presents two unique challenges to investigators. First, because each criminal organization running a FakeAV affiliate system regularly alters the appearance of their system, it is sometimes difficult to know whether an incoming criminal complaint or malware sample is related to one ring or the other. Secondly, because FakeAV is delivered in a “Pay Per Install” affiliate model, in addition to the ring-leaders of each major ring, there are many high-volume malware infection rings who are all using …

Annual ADFSL Conference on Digital Forensics, Security and Law

There has been extensive work in crime scene reconstruction of physical locations, and much is known in terms of digital forensics of computing devices. However, the network has remained a nebulous combination of entities that are largely ignored during an investigation due to the transient nature of the data that flows through the networks. This paper introduces an architecture for network path reconstruction using the network layer reachability information shared via OSPF Link State Advertisements and the routines and functions of OSPF::rt_sched() as applied to the construction of identical Link State Databases for all routers within an Area.

Application Of Toral Automorphisms To Preserve Confidentiality Principle In Video Live Streaming, Enrique García-Carbajal, Clara Cruz-Ramos, Mariko Nakano-Miyatake

Annual ADFSL Conference on Digital Forensics, Security and Law

Most of the Live Video Systems do not preserve the Confidentiality principle, and send all frames of the video without any protection, allowing an easy “man in the middle” attack. But when it does, it uses cryptographic techniques over streaming data or makes use of secure channel systems. This generates low frame rate and demands many processor resources. In fact native Live Video Streaming demands many resources of all System.

In this paper we propose a technique to preserve confidentiality in Video Live Streaming applying a confusing visual method making use of the Toral Automorphism Spatial Transformation over each frame. …

Applying Memory Forensics To Rootkit Detection, Igor Korkin, Ivan Nesterov

Annual ADFSL Conference on Digital Forensics, Security and Law

Volatile memory dump and its analysis is an essential part of digital forensics. Among a number of various software and hardware approaches for memory dumping there are authors who point out that some of these approaches are not resilient to various anti-forensic techniques, and others that require a reboot or are highly platform dependent. New resilient tools have certain disadvantages such as low speed or vulnerability to rootkits which directly manipulate kernel structures, e.g., page tables. A new memory forensic system – Malware Analysis System for Hidden Knotty Anomalies (MASHKA) is described in this paper. It is resilient to popular …

The Federal Rules Of Civil Procedure: Politics In The 2013-2014 Revision, John W. Bagby, Byron Granda, Emily Benoit, Alexander Logan, Ryan Snell, Joseph J. Schwerha

Annual ADFSL Conference on Digital Forensics, Security and Law

Pre-trial discovery is perpetually controversial. Parties advantaged by strict privacy can often avoid justice when this is disadvantageous to their interests. Contrawise, parties advantaged by relaxed litigation privacy can achieve justice when all facts are accessible irrespective of their repositories, ownership or control. American-style pre-trial discovery in civil and regulatory enforcement is relatively rare around the world. U.S. discovery rules open nearly all relevant and non-privileged data for use by opposing parties. The traditional discovery process was costly and time consuming in the world of tangible paper data. However, these burdens have increased, rather than diminished as often predicted, as …

Why Penetration Testing Is A Limited Use Choice For Sound Cyber Security Practice, Craig Valli, Andrew Woodward, Peter Hannay, Mike Johnstone

Annual ADFSL Conference on Digital Forensics, Security and Law

Penetration testing of networks is a process that is overused when demonstrating or evaluating the cyber security posture of an organisation. Most penetration testing is not aligned with the actual intent of the testing, but rather is driven by a management directive of wanting to be seen to be addressing the issue of cyber security. The use of penetration testing is commonly a reaction to an adverse audit outcome or as a result of being penetrated in the first place. Penetration testing used in this fashion delivers little or no value to the organisation being tested for a number of …

Finite Element Modeling Of Macro Fiber Composite Actuators With Application To Wing De-Icing, Boutros Youssef Azizi

Doctoral Dissertations and Master's Theses

Icing can have a profound impact on aircraft performance during inclement weather conditions. Aircraft icing primarily occurs on the leading edge of wings, tails and engines. The de-icing/anti-icing technologies currently in use are typically bulky, heavy, cover the entire airfoil surface and consume high energy. These drawbacks highlight the need for a de-icing technique that can overcome some or all of the aforementioned problems. Therefore, in this thesis, a proposed de-icing technique is studied in which lightweight Macro Fiber Composite (MFC) actuators are used to break the adhesive bond between the leading edge of a wing and an accumulated ice …

A Fast Algorithm For The Inversion Of Quasiseparable Vandermonde-Like Matrices, Sirani M. Perera, Grigory Bonik, Vadim Olshevsky

Publications

The results on Vandermonde-like matrices were introduced as a generalization of polynomial Vandermonde matrices, and the displacement structure of these matrices was used to derive an inversion formula. In this paper we first present a fast Gaussian elimination algorithm for the polynomial Vandermonde-like matrices. Later we use the said algorithm to derive fast inversion algorithms for quasiseparable, semiseparable and well-free Vandermonde-like matrices having O(n2) complexity. To do so we identify structures of displacement operators in terms of generators and the recurrence relations(2-term and 3-term) between the columns of the basis transformation matrices for quasiseparable, semiseparable and well-free polynomials. Finally we …

Then, contemporary approaches related to the principles of measuring software properties are discussed, with emphasis on statistical, physical and software models. A distinction between metrics and measures is made to clarify the concepts. A brief overview of inadequacies of methods and techniques to evaluate computer security is presented, followed by …

Idiographic Digital Profiling: Behavioral Analysis Based On Digital Forensics, Chad M. Steel

Journal of Digital Forensics, Security and Law

Idiographic digital profiling (IDP) is the application of behavioral analysis to the field of digital forensics. Previous work in this field takes a nomothetic approach to behavioral analysis by attempting to understand the aggregate behaviors of cybercriminals. This work is the first to take an idiographic approach by examining a particular subject's digital footprints for immediate use in an ongoing investigation. IDP provides a framework for investigators to analyze digital behavioral evidence for the purposes of case planning, subject identification, lead generation, obtaining and executing warrants, and prosecuting offenders.
