Data Filtering Unit (DFU): Dealing With Cryptovariable Keys in Data Recorded Using the IRIG 106 Chapter 10 Format

Manning, Dennis, Williams, Rick, Ferrill, Paul 10 1900 (has links)
ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / Recent advancements in IRIG 106 Chapter 10 recording systems allow the recording of all on board 1553 bus and PCM traffic to a single media. These advancements have also brought about the issue of extracting data with different levels of classification that was written to single location. Carrying GPS “smart” weapons further complicates this issue since the recording of GPS keys adds another level of classification to the mix. The ability to separate and/or remove higher level data from a data product is now required. This paper describes the design of a hardware device that will filter specified data from IRIG 106 Chapter 10 recorder memory modules (RMMs) to prevent the storage device or computer from becoming classified at the level of the specified data.

Characteristics of Exemplary Teachers as Part of Georgia's Vision for Public Education

McDermon, Kimberly A, McDermon, Kimberly A 13 May 2016 (has links)
Background: Improving instruction and rewarding educators for student learning creates a paradigm shift in evaluating a teacher’s contribution to individual learners. Systemic performance and teacher performance are now receiving more attention than ever before in history, as they are considered foundational for student performance. Policy makers are concerned about teacher quality and want a non-subjective measure that compares teachers based on student achievement results. Superintendents and school boards are joining forces to produce frameworks that are designed to guide school districts through strategic planning. The Vision for Public Education, Equity and Excellence in Georgia is one example. Purpose: The primary focus of this dissertation is to examine A Vision for Public Education, Equity and Excellence, a state-wide project to improve public education in Georgia. The aim of the project is to influence school board policy in seven areas, early learning and student success, teaching and learning, teaching and learning resources, human and organizational capital, governance, leadership, and accountability. Research Methods: A case study provides how individual school boards are implementing the Georgia Vision Project’s recommendations, particularly teacher evaluation. The districts chosen for this study met the criteria of implementing the Vision Project with fidelity and were deemed to be addressing teacher evaluation with commitment. An instrumental case study design allowed for an in-depth look at the Vision Project’s effect on two districts. Findings: Findings reveal how two school districts in Georgia actively used the recommendations from the Vision for Public Education to strengthen strategic planning in multiple areas. Results show how exemplary teachers, building leaders, and district leaders are aligning efforts to improve the educational experience for students. This dissertation describes common themes in student data uses, teacher evaluation, and clarity of communication to benefit student achievement. Conclusion: The results suggest the Vision Project recommendations overlapped showing the complexity of school organizations. Each district used the recommendations differently however, clarity, communication and a focus on students emerged as commonalities. Hopes and fears concerning teacher evaluation arose as teachers discussed current policy requiring student test data be incorporated into teacher evaluations.

A historical study and evaluation of the form of church government practised by the Particular Baptists in the 17th and 18th centuries / Boon-Sing Poh

Poh, Boon-Sing January 2012 (has links)
This thesis is a historical study and evaluation of the form of church government practised by the Particular Baptists of the 17th and 18th centuries, from the years 1650 to 1750. This study is based on confessional statements, the ecclesiological literature, and the extant church books of the Particular Baptists. It is shown that the Particular Baptists practised a definitive form of church government known traditionally as Independency, similar to that expounded by John Owen, minus infant baptism. Under the principle of the autonomy of the church the Particular Baptists practised believer’s baptism, an explicit church membership, and upheld covenant theology. Under the principle of the headship of Christ, they practised the separation of church and state, upheld the divine right of the magistrate, and also believed in the liberty of conscience. Under the principle of rule by elders the majority of the Particular Baptists practised a plurality of elders in which there was a distinction made between the roles of the pastor or minister and the ruling elders, although they occupy the same basic office of rule. However, deviation from a plural eldership took place, leading to the singlepastor- and-multiple-deacons situation, accompanied by the disappearance of ruling elders and the practice of congregational democracy in governance. This arrangement is characteristic of modern Congregationalism. Under the principle of the communion of churches the regional associations of churches accomplished much good, while a number of issues remained unresolved, including open and closed communion, congregational hymn singing, and the training of ministers. In the final chapter, the study attempts to resolve some ecclesiological issues controverted among Reformed Baptists today by applying the lessons learned from the Particular Baptists. To the Particular Baptists, Independency was the jus divinum (divinely ordained) form of church government used by God as the vehicle to carry out the Great Commission with a view to establishing biblically ordered churches, which upheld the 1689 Baptist Confession of Faith. These three components of church life − mission-mindedness, biblical church order, and the 1689 Confession of Faith − arose from the thorough biblicism of the Particular Baptists. / Thesis (Ph.D. (Church and Dogma History))--North-West University, Potchefstroom Campus, 2012

Falken från öst eller korpen från väst? : En analys av bronserade nycklar med fågelmotiv från Kyrksundet i sydvästra Finland / The eastern falcon or the western raven? : An analysis of the bronzed keys with bird motif from Kyrksundet in southwestern Finland

Winter, Jan-Robert January 2019 (has links)
This paper contains an analysis of the bronzed keys with bird motifs that were discovered during archaeological investigations between the years 1991 and 1997 at Kyrksundet, in the archipelago of southwestern Finland. Bronzed keys with bird motifs have never been found in Finland before, but similar keys have been found both in Birka and on Gotland, Sweden. The aim with this paper is firstly to analyse and compare the keys from Kyrksundet, Birka and Gotland, and their find contexts. Secondly, together with the results from the analysis, the following questions will be discussed; What is the meaning behind the bird motif, why can these keys be found at Kyrksundet, and who were the people that had these keys in their possession during the Viking Age. The symbolic aspect of the keys is a strong theme in this discussion, because the underlaying theory in this paper is that the keys most likely had both a worldly and a cosmological meaning. Earlier archaeological investigations mainly have associated these keys with the Nordic peoples and their eastern connections during the Viking Age. Reason behind this association is that the birds on the motif have been interpreted as falcons and the falcon has a relatively strong connection to the Rurik dynasty that ruled in Novgorod and Kiev. Whether the bird is a falcon or not, is however a question that will be discussed in this paper. The analysis performed in this paper, shows that the bird motif on the keys shares more similarities with a raven motif that was used on the British Isles than with the falcon motif that was used in Novgorod and Kiev. This paper will therefore include a suggestion for another perspective, where the keys might be connected to the Nordic peoples and their western connections.

An Archaeological Study of Architectural Form and Function at Indian Key, Florida

Driscoll, Kelly A 31 October 2003 (has links)
Indian Key Historic State Park is a small island located on the Atlantic Ocean side of the Florida Keys, near Islamorada. Before it was bought by the state of Florida in 1970, Indian Key had been the setting for a number of historically significant activities. The most well known of these is the 1840 raid on the people and buildings that made up a small wrecking village, established on the island by Jacob Housman in the early 1830s. The limestone foundations of these structures are the main attraction to today's visitor to the park. There is more to the story of Indian Key, though, than the Housman period and the structural remains left behind from this stage of the island's history. Almost immediately after the near destruction of the island in 1840, the Florida Squadron of the Navy took over, constructing their own buildings, and re-using some of the previously constructed foundations. This cycle of rebuilding and re-use continued for another hundred years, with families and fishers trying to inhabit and profit from Indian Key. The focus of this thesis is to examine the foundations and associated archaeological features of Indian Key in order to determine better periods of use and re-use for the buildings that have been identified through archaeological investigations. This research was conducted in order to examine the site's architecture through an archaeological perspective; it is by no means an attempt at a complete architectural study of the site. Rather, it is an effort to examine the entire island of Indian Key, by focusing on the history of the buildings that helped make it an important piece of Florida's past.

Count or Pointcount: Is Percent Octocoral Cover an Adequate Proxy for Octocoral Abundance?

Lybolt, Matthew J 04 April 2003 (has links)
The Florida Keys Coral Reef Monitoring Project (CRMP) began video transect sampling in 1996 and has continuously monitored 107 Florida Keys stations through 2002. The video was downward pointing and produced images from which planar projection data were calculated to determine percent cover of living benthic organisms. An absence of data assessing correlation between octocoral percent cover and octocoral abundance motivated a study to compare octocoral percent cover with abundance data acquired from the same video transects. The methods employed to extract octocoral abundance data from videotape were validated. Temporal changes in octocoral abundance, size and taxonomic group were determined by examination of video transects of 28 randomly selected stations from 1996, 1998, 1999, and 2002. Size classes were defined as40cm (short, medium and tall respectively). Taxonomic groups were Gorgonia ventalina and "other octocorals" in three size classes, and Scleraxonia. An in situ study assessed the accuracy of video-derived counts. Average densities of G. ventalina and Scleraxonia were consistently about one colony/m2. Other octocoral as a group averaged 7-9 colonies/m2. When summarized by height, short and tall averaged about 1-2 colonies/m2, while colonies between 10 and 40 cm in height consistently averaged about 6 colonies/m2. Hurricane Georges, in September 1998, impacted the octocoral assemblage. Abundance declined most at stations near the storm center and stations in shallower water. Storm impact was related to octocoral height. Tall octocorals were removed more frequently than medium, short and encrusting forms. A dramatic increase of short individuals in 2002 is indicative of successful post-hurricane recruitment. By 2002, octocoral abundance had recovered to pre-hurricane levels. This study demonstrated that abundance data can reliably be derived from archived video data, reinforcing the value of standardized video data archives. Octocoral abundance and octocoral percent cover are not strongly correlated because tall individuals disproportionately influence percent cover estimates. Nevertheless, trends in octocoral percent cover are reliable indicators of the trends in octocoral abundance.

Dynamics and Survival of Coral and Octocoral Juveniles following Disturbance on Patch Reefs of the Florida Reef Tract

Bartlett, Lucy 28 October 2014 (has links)
Over the past several decades, rapid decline in adult stony-coral (comprising the Orders Scleractinia and Anthomedusae, specifically Family Milleporidae) cover has occurred concurrent with an increase in adult octocoral (Octocorallia/gorgonian) cover along the Florida Reef Tract. In January 2010, the Florida Keys experienced extremely cold air and water temperatures, below the lethal threshold for many reef organisms including corals. Very high stony-coral mortality occurred on some patch reefs. The newly-available space created by this disturbance event provided the opportunity for recruitment and settlement of new coral larvae and other reef organisms. The goal of this study was to examine post-disturbance recruitment and survival of juvenile stony corals and octocorals on patch reefs in the Middle and Upper Florida Reef Tract. Permanent quadrats were established at eight patch-reef sites. Stony-coral and octocoral juveniles, visible to the naked eye and having a maximum 4 cm diameter for stony corals or 4 cm height for octocorals, were identified, measured, and photographed to track each colony through spring and fall for two years. Juvenile densities increased significantly over that time; octocoral density increased with higher significance (p Opportunistic and/or hardy organisms are re-populating patch-reef sites, whereas slower growing, massive stony-coral species are declining. When a reef environment is plagued with chronic stressors, such as terrestrial runoff, overfishing, high temperature fluctuations and turbidity, the succession process may be inhibited following acute disturbances such as cold-water events. Patch reefs of the Florida Reef Tract now appear to be caught in a perpetually disturbed state, which supports opportunistic and hardy taxa and inhibits recovery of slower-growing climax taxa that dominated until the past few decades.

Efficient Secure Electronic Mail Protocols with Forward Secrecy

Hsu, Hsing 07 September 2007 (has links)
In 1976, Diffie and Hellman proposed the concept of public key cryptosystem (PKC). The application and research of public key cryptography are arisen in the modern cryptography. In 2005, Sun, Hsieh, and Hwang (S.H.H.) proposed an electronic mail protocol based on classic public key cryptography. The technique of the Certificate of Encrypted Message Being a Signature (CEMBS) that Bao proposed in 1998 is applied on session key sharing of their e-mail system. In the same year, Dent pointed out that the first one of S.H.H.¡¦s e-mail protocols cannot suffice the property of forward secrecy. Thus, Kim, Koo, and Lee (K.K.L.) proposed two e-mail protocols based on signcryption concept which is proposed by Zheng in 1997 to overcome the flaw of S.H.H.¡¦s e-mail protocol in 2006. Lin, Lin, and Wang (L.L.W.) pointed out that the second one of S.H.H.¡¦s protocols cannot achieve forward secrecy and then they improved the protocol. In 2007, Yoon and Yoo claimed that the second one of K.K.L.¡¦s protocols is still vulnerable to two possible forgery attacks. In this thesis, we will make deep discussions about secure e-mail protocols based on PKC with providing the property of forward secrecy and then build a novel e-mail protocol to withstand the above attacks. Our proposed e-mail protocol can achieve the properties of authentication, confidentiality, integrity, non-repudiation and forward secrecy.

Hidden Creatures – systematics of the Euphorinae (Hymenoptera)

Stigenberg, Julia January 2013 (has links)
Parasitic wasps constitute one of the last remaining frontiers in the charting of animal diversity. The Braconidae is the second most species-rich family of parasitic wasps; the world fauna has been estimated at 40 000 species and the Swedish fauna is believed to include a little more than 2 000 species, 1 200 of which are currently documented. This thesis is a contribution to the rapidly increasing knowledge of braconid diversity. In paper I, a new gregarious parasitoid, Meteorus acerbiavorus sp. nov. (Braconidae: Eupohrinae), is described from specimens reared from the cocoons of the butterfly Acerbia alpina (Quensel) (Lepidoptera, Arctiidae) in northwestern Finnish Lapland. Based on a molecular phylogenetic analysis, the new species is shown to belong to the M. rubens species group. In the second paper, the Western Palearctic fauna of the tribe is revised, seven new species are described and a key to the Western Palearctic species is presented. Two molecular markers, 28S and COI, are used to study phylogenetic relationships in the tribe. The molecular results showed that the Meteorini fall into four well supported clades. The results also reveal a considerable cryptic species diversity. The third paper deals with distributional, phenological and in many cases rearing data from nearly 2 500 specimens (44 species) of the Meteorini in the collection of the National Museums of Scotland (NMS), Edinburgh. Patterns in the breadth of host ranges are discussed in relation to a reiterated speciation hypothesis. Paper IV examines the phylogenetic relationships of the entire subfamily Euphorinae based upon four gene regions (18S, CAD, 28S D2, and COI). A revised classification of the Euphorinae is proposed that recognizes 55 genera and 14 tribes. Our study shows that early members of the Euphorinae were parasitoids of coleopteran larvae, with a host shift to larval Lepidoptera, adult or immature hosts in the Hemiptera, Hymenoptera, Neuroptera, Orthoptera and Psocoptera. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: In press.

Personal Creative Process ¡V From Integrating Motivation Theories¡¦ Conceptions

Li, Tzung-Luen 30 June 2004 (has links)
Always, researchers are trying to use different ways to describe the concept ¡§Motivation¡¨. Different definition of motivation will develop different theory. However, there are two points under below at least: First is the fitness of the culture, the concept of the Western would have the specific background, will not fit in the individual person with other culture. Second, to ease the verifying of the science, most of the researches only discuss the relationship of immediate variables but neglect the influence of individual personality in different points of time. This study will combine the concepts of motivation and creativity through integrating work motivation theories and following up Teresa M. Amabile¡¦s research to build up the ¡§Personal Creative Process Model¡¨. The research model includes: the environment of organization, the process of perception, motivation, behavior and outcome. Especially, process of perception includes personality, criterion and response. ¡§Criterion¡¨ refers to personal need and value which are influenced by social environment and culture in country. Addition, ¡§Response¡¨ refers to attitude and emotion which are influenced by time. In this study, I use the concepts, ¡§Criterion¡¨ and ¡§Response¡¨, to compensate the loss of old motivation theories. Supposing the variable, ¡§Criterion¡¨, is determined, this study¡¦s purpose will find out the relationship of other variables and how these variables influence creativity. Next, using questionnaire to capture responses of college student and work adult will help us to understand the relationship of these responses. The questionnaire, this study uses, includes: ¡§Cognitive Style Instrument¡¨, ¡§What Is Happening in This Class? Questionnaire¡¨, ¡§KEYS¡¨ and ¡§The Work Preference Inventory¡¨. In addition, this study uses the grade of students to represent personal creativity and analyze the relationship between creativity and other constructs. The conclusion shows cognitive style indeed affects creativity, but the relations are different from theory. Furthermore, cognitive style and response/motivation are almost independent. To infer, the response and motivation are intervening variables between personality and creativity. Finally, regression analysis by students, this study got the result: ¡§Close by the factor is the key element of the creativity performance¡¨.
