Reliable design of micro-satellite systems using combined physics of failure reliability estimation modelsHussmann, Cass Adam 04 July 2016 (has links)
Up until 2015 the rate at which cube satellite missions achieved full mission success
was only 44.1% for any organizations rst mission (academic or corporate), the success
rate increases to only 62% for cube satellites launched as a second mission. This
thesis suggests that there are two main sources for the high failure rate: improper
veri cation, and the common use of COTS components and their reliability in a
space environment. The thesis provides a means of increasing mission assurance
through the use of physics of failure reliability estimation models that incorporate
the intrinsic and extrinsic failures of thermal mechanical e ects as well as radiation
e ects on EEE components, a design methodology is also presented that incorporates
reliability modeling as well as thorough software and hardware in loop testing to
prevent failure due to improper veri cation. The environment and reliability models
are calculated for the on board command and data handling system of the ECOSat-
II cube satellite being developed by the University of Victoria ECOSat team using
NX Siemens for thermal FEA modelling, SPENVIS for radiation environment, and
MATLAB for reliability calculation. / Graduate / 0544 / 0538 / cass.hussmann@gmail.com

Mission Analysis of the Nanosatellite SonateHermannsdörfer, Nadine January 2017 (has links)
The objective of this thesis is the development of a software application facilitating a quick and extensive mission analysis including all subsystems of the satellite. Furthermore mission analysis for the Sonate mission is done, utilizing the developed program. Usually mission analysis is done by applying separately different tools which are specific for each subsystem. The drawback of this method is that the system is not analyzed as a whole; rather all subsystems are investigated separately from each other. In case one or more system parameters should change, the effect of this variation onto other parts of the system will not directly be accessible and visible. A simulation tool considering all these subsystems overcomes this weaknesses and helps to develop a balanced system. Different system configurations and operation scenarios can be evaluated quickly and compared to each other in order to find an optimal solution. The simulation system developed during this thesis exhibits a client-server structure, where the subsystems are separated modules acting as clients. The program has a highly modular structure which renders it possible to have an arbitrary extension in the future. Aside from the server, connecting all modules, the following modules were implemented: orbital dynamics module containing orbit propagation and attitude determination power subsystem consisting of the subparts power production, power consumption and power storage archiving module saving all results generated for further evaluation simulation clock providing the simulation time configuration module with a GUI to facilitate the configuration of all simulation parameters simple thermal module providing temperatures for the satellite panels Mission analysis was done for the Sonate satellite utilizing the developed program in order to find a configuration for the solar panels of the satellite such that all the subsystems of the satellite can be supplied with sufficient power during the mission.

The nature of the ministry of school chaplains in Church of England secondary schoolsCaperon, John P. January 2012 (has links)
This thesis argues that since in our increasingly secularised culture one of the very few direct points of contact between the Church of England and the young is the ministry of school chaplains, theirs is a vital ministry for the Church and its future. The study described in the thesis researched school chaplaincy in Church of England secondary schools to establish what chaplains do, how they understand their ministry and how school students themselves respond to chaplaincy. Originating in the researcher’s professional role in support of school chaplains, the research was undertaken on a multi-method basis. Initial scoping interviews were undertaken with school chaplains and headteachers in a range of schools. A full literature review located school chaplaincy within the conceptual contexts of missiology, ministry and chaplaincy. In-depth interviews with school chaplains explored their self-understanding as ministers. A national, internet-based survey of all contactable school chaplains was undertaken to explore issues identified earlier in the study, and a series of focus-group interviews was undertaken with senior school students. The research revealed that chaplains perceive little awareness within the Church of England of the missional significance of their ministry, although individual chaplains emerged as highly-motivated spiritual professionals committed to the pastoral welfare of their communities, and with a strong sense of their mission as ‘God people’. From a wide variety of ecclesial and personal backgrounds and working in very different school contexts, chaplains have multiple, significant functions which are well understood by school students, and exercise a ‘ministry of presence’. The research evidence highlights the need for greater recognition of the ministry of school chaplains and for structures of support and development to resource this vital ministry. The thesis concludes with an outline of policy proposals for the Church in the light of the recent development of a new ‘para-chaplaincy’.

The People of God: Toward an Evangelical EcclesiologySanchez, Juan Ramon 12 January 2016 (has links)
ABSTRACT
THE PEOPLE OF GOD:
TOWARD AN EVANGELICAL ECCLESIOLOGY
Juan Ramon Sanchez, Jr., Ph.D.
The Southern Baptist Theological Seminary, 2015
Chair: Dr. Gregg R. Allison
This dissertation argues that in a day of ecclesiological confusion among evangelicals over who belongs to the church and what the mission of the church is, the biblical concept of the image of God interpreted in its textual, redemptive-historical, and canonical contexts reveals a common pattern for the people of God that serves as an interpretive key to understanding the identity, nature, and mission of the church. Chapter 1 recounts much of the confusion over the doctrine of the church within evangelicalism and exposes the need for such a proposal.
Chapter 2 proposes that the creation of man as God’s image reveals God’s purpose to create (1) a people with whom he will relate in a father/son relationship (sonship) under his rule and care (covenant), (2) a people who will dwell in his presence to serve him as priests (priesthood) and (3) a people who will represent his sovereign rule on the earth (kingship) by exercising dominion over creation by extending the borders of the sacred space and reproducing the divine image through godly offspring until the entire earth is filled with the glory of God (mission). Thus, it establishes the foundation for the thesis that the concept of the image of God communicates sonship, kingship, and priesthood within a covenant relationship in which God’s people serve as God’s instruments by which he establishes his kingdom on the earth.
Chapter 3 shows how the pattern for the people of God established in the garden continues in Abraham and Israel. It also shows that king David is a prototypical image bearer who points to a future messianic Adam who will ultimately establish God’s kingdom on the earth.
While Israel failed to keep covenant and image God faithfully, judgment is not the final word. Instead, the biblical storyline looks forward to a new covenant yet to be established by a faithful Davidic messiah. Chapter 4, then, investigates the new covenant passages in Isaiah, Jeremiah, and Ezekiel by utilizing Isaiah 54-56 as a structure for understanding what the new covenant entails.
Chapter 5 addresses the New Testament data related to Jesus as the last Adam. The chapter shows that Jesus is the Son of God from David’s line who came to restore Israel on the basis of a new covenant. This messianic mission reveals that Jesus is the true and faithful image of God who inaugurates the kingdom of God on the earth and begins populating it with the divine image by gathering a people through the gospel.
Chapter 6 shows that the pattern of the people of God established in Genesis 1 and 2 is also found in the church: sonship, kingship, priesthood, and mission within a covenant relationship. This chapter argues that the New Testament applies the language of Israel (Exod 19:4-6) to the church (1 Pet 2:9) because it is the new Israel constituted on the basis of the promised new covenant, created to serve as a corporate Adam for the purpose of mission. As a corporate Adam, the church is called to image God on the earth and fulfill the mission of eschatological ingatheing until the return of Christ.
Chapter 7 provides theological conclusions from the biblical data in the previous chapters and proposes a definition of the church that helps to clarify the identity and mission of the people of God under the new covenant. And finally, it proposes a path toward constructing an ecclesiology that is biblically faithful and culturally appropriate.

Lay Pastoring of the Parish: Prospering the MissionHintz, Debra Unknown Date (has links)
In more dioceses each year there are parish communities living without a resident priest - more than 3000 priestless parishes in the USA. Several models of administration exist in this set of circumstances, each one aiming not only to maintain the parish, but also to prosper in carrying forward the mission of the church locally. Hintz shared her training and experience as a parish administrator. / Presenter: Debra Hintz, Parish Director, Saint Catherine of Alexandria Catholic Church (Milwaukee, WI) / Higgins Hall 300

Design and Development of Ground Segment Software and Hardware for Nanosatellie Space MissionsMehradnia, Payam 05 December 2013 (has links)
Contributions to two nanosatellite missions are discussed. First, the design and development of a test system for an advanced nanosatellite power board is discussed. Details of software and hardware design process involved in the implementation of automated test procedures are presented. The system has been deployed for unit-level testing of power boards for several nanosatellite missions, significantly reducing testing cost and time. Next, a Mission Planning and Scheduling Software platform is proposed for Earth Observation missions. The motivation is described for the development of a stand-alone application enabling satellite operations teams to identify suitable observation scenario parameters. Attitude and orbital trajectory estimation algorithms constituting the computational model are integrated and implemented within a graphical visualization environment to allow interaction with the user in an efficient and intuitive manner. Key results of major component-level testing are presented, showing the behaviour and accuracy of analytical components satisfy mission requirements.
