An Empirical Analysis of the Cascade Secret Key Reconciliation Protocol for Quantum Key Distribution
ISBN: 9781511581929 / Angielski / Miękka / 2015 / 80 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The need to share key material with authorized entities in a secure, efficient and timely manner has driven efforts to develop new key distribution methods. The most promising method is Quantum Key Distribution (QKD) and is considered to be "unconditionally secure" because it relies upon the immutable laws of quantum physics rather than computational complexity. Unfortunately, the non-idealities present in actual implementations of QKD systems also result in errors manifested in the quantum data channel. As a consequence, an important component of any QKD system is the error reconciliation...

Augmenting Latent Dirichlet Allocation and Rank Threshold Detection with Ontologies
ISBN: 9781502959485 / Angielski / Miękka / 2014 / 104 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. In an ever-increasing data rich environment, actionable information must be extracted, filtered, and correlated from massive amounts of disparate often free text sources. The usefulness of the retrieved information depends on how we accomplish these steps and present the most relevant information to the analyst. One method for extracting information from free text is Latent Dirichlet Allocation (LDA), a document categorization technique to classify documents into cohesive topics. Although LDA accounts for some implicit relationships such as synonymy (same meaning) it often ignores other...

Trajectory Optimization for Spacecraft Collision Avoidance
ISBN: 9781500903138 / Angielski / Miękka / 2014 / 130 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The last several decades have resulted in an unfortunate byproduct of space exploration and development: orbital debris. Satellites in Low Earth Orbit have been required to make an ever increasing number of course corrections in order to avoid collisions. Despite efforts to the contrary, collisions continue to occur, each time creating additional debris and increasing the requirement for the remaining satellites to maneuver. Every required maneuver decreases a satellite's service life. The purpose of this study is to develop a minimum thrust profile to maneuver an orbiting satellite out of...

An Analysis of Eye Movements With Helmet Mounted Displays
ISBN: 9781511581936 / Angielski / Miękka / 2015 / 102 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Helmet or Head-Mounted Displays (HMD) applications have expanded to include a range from advanced military cockpits to consumer glasses. However, users have documented loss of legibility while undergoing vibration. Recent research indicates that undesirable eye movement is related to the vibration frequency a user experiences. In vibrating environments, two competing eye reflexes likely contribute to eye movements. The Vestibulo-ocular Reflex responds to motion sensed in the otoliths while the pursuit reflex is driven by the visual system to maintain the desired image on the fovea. This study...

Speech Recognition Using the Mellin Transform
ISBN: 9781502959430 / Angielski / Miękka / 2014 / 54 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The purpose of this research was to improve performance in speech recognition. Specifically, a new approach was investigating by applying an integral transform known as the Mellin transform (MT) on the output of an auditory model to improve the recognition rate of phonemes through the scale-invariance property of the Mellin transform. Scale-invariance means that as a time-domain signal is subjected to dilations, the distribution of the signal in the MT domain remains unaffected. An auditory model was used to transform speech waveforms into images representing how the brain "sees" a sound. The...

ISBN: 9781511658218 / Angielski / Miękka / 2015 / 98 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The 1970s were a period of great transition for the United States. Plagued by the Vietnam conflict, a conflict which we could never win because of poor planning and lack of resolve by government officials in the highest office, and the Watergate debacle, where our government veered out of control, the time was ripe for change. Which is precisely why the ideals and philosophies of one James Earl Carter enabled him to ascend to become the 39th President of the United States. President Carter entered office pledging the United States would lead the way in the restriction of weapons exports and...

Strengthening DoD Cyber Security with the Vulnerability Market
ISBN: 9781500750152 / Angielski / Miękka / 2014 / 70 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Every year, the DoD upgrades its information technology systems, allows new applications to connect to the network, and reconfigures the Enterprise to gain efficiencies. While these actions are to better support the warfighter and satisfy national security interests, they introduce new system vulnerabilities waiting to be exploited. Often, these vulnerabilities are discovered after the system has already deployed and where costs to fix are much larger. This paper recommends the DoD adopt an Information Assurance tactic to limit these costs, called the vulnerability market. Through use of the...
