ADAM SMITH'S OPTIMISTIC TELEOLOGICAL VIEW OF HISTORY
No full textAdam Smith's four-stage theory provides the framework for his writings on history. The fourth stage is the commercial epoch; the culmination of history in this stage is a key component in the conventional interpretation of Adam Smith as a prophet of commercialism. In two historical case studies Smith shows the capacity of commercial society to regenerate itself. This potent capacity suggests that commercial society is inevitable. At a certain point in time it also overcomes the major obstacles to its permanence. Smith's philosophy of history anticipates the end of history views of Kant and Hegel.Political Economy,
THE THEOLOGICAL FOUNDATION OF ADAM SMITH'S WORK
No full textThe paper will discuss the theological foundation to Smith's writings. Teleology, final causes and divine design were initially seen as central to understanding Smith's writings. Over time, this view fell out of fashion. In the period after World War II, with the rise of positivism, commentators tended to overlook or downplay this interpretation. In the last decade, or so, teleology has started to be restored to its former position as an essential element in understanding Smith. After spelling out Smith's teleology and his view of final causes, divine design and the ends of nature, we try to explain the Panglossian nature of the 'new theistic view' of Smith. While our view differs somewhat, we agree with the essence of the 'new view' claim: a theological view exists in Smith which underpins his moral and economic theories.Political Economy,
Autonomous Swarm Navigation
No full textRobotic swarm systems attract increasing attention in a wide variety of applications, where a multitude of self-organized robotic entities collectively accomplish sensing or exploration tasks. Compared to a single robot, a swarm system offers advantages in terms of exploration speed, robustness against single point of failures, and collective observations of spatio-temporal processes.
Autonomous swarm navigation, including swarm self-localization, the localization of external sources, and swarm control, is essential for the success of an autonomous swarm application. However, as a newly emerging technology, a thorough study of autonomous swarm navigation is still missing.
In this thesis, we systematically study swarm navigation systems, particularly emphasizing on their collective performance. The general theory of swarm navigation as well as an in-depth study on a specific swarm navigation system proposed for future Mars exploration missions are covered.
Concerning swarm localization, a decentralized algorithm is proposed, which achieves a near-optimal performance with low complexity for a dense swarm network.
Regarding swarm control, a position-aware swarm control concept is proposed. The swarm is aware of not only the position estimates and the estimation uncertainties of itself and the sources, but also the potential motions to enrich position information. As a result, the swarm actively adapts its formation to improve localization performance, without losing track of other objectives, such as goal approaching and collision avoidance.
The autonomous swarm navigation concept described in this thesis is verified for a specific Mars swarm exploration system. More importantly, this concept is generally adaptable to an extensive range of swarm applications
Superposition Mapping & Related Coding Techniques
No full textSince Shannon's landmark paper in 1948, it has been known that the capacity of a
Gaussian channel can be achieved if and only if the channel outputs are Gaussian. In the low signal-to-noise ratio (SNR) regime, conventional mapping schemes suffice for approaching the Shannon limit, while in the high SNR regime, these mapping schemes, which produce uniformly distributed symbols, are insufficient to achieve the capacity. To solve this problem, researchers commonly resort to the technique of signal shaping that mends the symbol distribution, which is originally uniform, into a Gaussian-like one.
Superposition mapping (SM) refers to a class of mapping techniques which use linear superposition to load binary digits onto finite-alphabet symbols that are suitable for waveform transmission. Different from conventional mapping schemes, the output symbols of a superposition mapper can easily be made Gaussian-like, which effectively eliminates the necessity of active signal shaping. For this reason, superposition mapping is of great interest for theoretical research as well as for practical implementations. It is an attractive alternative to signal shaping for approaching the channel capacity in the high SNR regime.
This thesis aims to provide a deep insight into the principles of superposition
mapping and to derive guidelines for systems adopting it. Particularly, the influence of power allocation to the system performance, both w.r.t the achievable power efficiency and supportable bandwidth efficiency, is made clear. Considerable effort is spent on finding code structures that are matched to SM. It is shown that currently prevalent code design concepts, which are mostly derived for coded transmission with bijective uniform mapping, do not really fit with
superposition mapping, which is often non-bijective and nonuniform. As the main
contribution, a novel coding strategy called low-density hybrid-check (LDHC) coding is proposed. LDHC codes are optimal and universally applicable for SM with arbitrary type of power allocation

Zechariah 9-14 as the substructure of 1 Peter’s eschatological program
No full textThe principal aim of this study is to discern what has shaped the author of 1 Peter to regard Christian suffering as a necessary (1.6) and to-be-expected (4.12) component of faithful allegiance to Jesus Christ. Most research regarding suffering in 1 Peter has limited the scope of inquiry to two particular aspects—its cause and nature, and the strategies that the author of 1 Peter employs in order to enable his addressees to respond in faithfulness. There remains, however, the need for a comprehensive explanation for the source that has generated 1 Peter’s theology of Christian suffering. If Jesus truly is the Christ, God’s chosen redemptive agent who has come to restore God’s people, then how can it be that Christian suffering is a necessary part of discipleship after his coming, death and resurrection? What led the author of 1 Peter to such a startling conclusion, which seems to runs against the grain of the eschatological hopes and expectations of Jewish restoration ideology?
This thesis analyzes the appropriation of shepherd and fiery trials imagery,
and argues that the author of 1 Peter is dependent upon Zechariah 9-14 for his
theology of Christian suffering. Said in another way, the eschatological program of
Zechariah 9-14, read through the lens of the Gospel, functions as the substructure
for 1 Peter’s eschatology and thus its theology of Christian suffering.
In support of this hypothesis, this study highlights the fact that Zechariah 9-
14 was available and appropriated in early Christianity, in particular in the Passion
Narrative tradition; that the shepherd imagery of 1 Pet 2.25 is best understood
within the milieu of the Passion Narrative tradition, and that it alludes to the
eschatological program of Zechariah 9-14; that the fiery trials imagery found in 1
Peter 1.6-7 and 1 Pet 4.12 is distinct from that which we find in Greco-Roman and OT
wisdom sources, and that it shares exclusive parallels with some unique features of
the eschatological program of Zechariah 9-14; that Zechariah 9-14 offers a more
satisfying explanation for the modification of Isa 11.2 in 1 Pet 4.14, the transition
from 4.12-19 to 5.1-4, why Peter has oriented his letter with the term διασπορά,
and why he has described his addresses as οἶκος τοῦ θεοῦ; and finally that 1 Peter
contains an implicit foundational narrative that shares distinct parallels with the
eschatological program of Zechariah 9-14.
We can conclude that 1 Peter offers a unique vista into the way in which at
least one early Christian witness came to understand and to communicate the fact
that Christian suffering was a necessary feature of faithful allegiance to Jesus Christ
Fictional Man: Ned Kelly in Peter Carey's True History of the Kelly Gang in Comparison with Older Portrayals
No full textTITLE: The Fictional Man: Ned Kelly in Peter Carey's True History of the Kelly Gang in Comparison with Older Portrayals AUTHOR: Adam Prentis DEPARTMENT: Department of English Language and Literature SUPERVISOR: PhDr. Petr Chalupský, Ph.D. ABSTRACT: The thesis concerns itself with the analysis of various personality aspects of the protagonist of Peter Carey's True History of the Kelly Gang (2000) - Ned Kelly. Albeit a historical figure, Ned Kelly is approached as a fictional character with focus placed on his symbolic status of Australian nationality, myth and manhood, and on the literary means that point to this. The separate aspects are placed in an evolutionary context through comparisons with older portrayals of the same character - in Max Brown's Australian Son (1948) and J. J. Kenneally's The Complete Inner History of the Kelly Gang and their Pursuers (1929), all of which use a heroising approach to the man. The work shows that Ned Kelly may be perceived in many complex ways, with further possibilities for analysis suggested. Comparing the three books, it is found that although considerable unifying tendencies and moments exist, some aspects have a significant difference in focus or emphasis. A shift is noted from a confrontational idealising defence of what is perceived as a historical person to a..

Effects and Constraints of Optical Filtering on Ambient Light Suppression in LED-Based Underwater Communications
No full textOptical communication promises to be a high-rate supplement for acoustic communication in short-range underwater applications. In the photic zone of oceanic and coastal waters, underwater optical communication systems are exposed by remaining sunlight. This ambient light generates additional noise in photodetectors, thus degrading system performance. This effect can be diminished by the use of optical filters. This paper investigates light field characteristics of different water types and potential interactions with optical underwater communication. A colored glass and different thin film bandpass filters are examined as filter/detector combinations under varying light and water conditions, and their physical constraints are depicted. This is underlined by various spectral measurements as well as optical signal-to-noise ratio calculations. The importance of matching the characteristics of the light emitting diode (LED) light source, the photodetector, and the filter on the ambient conditions using wider angle of incidents is emphasized
