Locally minimal uniformly oriented shortest networks
No full textAbstractThe Steiner problem in a λ-plane is the problem of constructing a minimum length network interconnecting a given set of nodes (called terminals), with the constraint that all line segments in the network have slopes chosen from λ uniform orientations in the plane. This network is referred to as a minimum λ-tree. The problem is a generalization of the classical Euclidean and rectilinear Steiner tree problems, with important applications to VLSI wiring design.A λ-tree is said to be locally minimal if its length cannot be reduced by small perturbations of its Steiner points. In this paper we prove that a λ-tree is locally minimal if and only if the length of each path in the tree cannot be reduced under a special parallel perturbation on paths known as a shift. This proves a conjecture on necessary and sufficient conditions for locally minimal λ-trees raised in [M. Brazil, D.A. Thomas, J.F. Weng, Forbidden subpaths for Steiner minimum networks in uniform orientation metrics, Networks 39 (2002) 186–222]. For any path P in a λ-tree T, we then find a simple condition, based on the sum of all angles on one side of P, to determine whether a shift on P reduces, preserves, or increases the length of T. This result improves on our previous forbidden paths results in [M. Brazil, D.A. Thomas, J.F. Weng, Forbidden subpaths for Steiner minimum networks in uniform orientation metrics, Networks 39 (2002) 186–222]
A note on the compression theorem for convex surfaces
No full textAbstractSuppose aibici(i=1,2) are two triangles of equal side lengths and lying on spheres Φi with radii r1,r2(r1<r2), respectively. We have proved that there is a continuous map h of a1b1c1 onto a2b2c2 so that for any two points p,q in a1b1c1,|pq|⩾|h(p)h(q)| (Rubinstein and Weng, J. Combin. Optim. 1 (1997) 67–78). In this note we generalize this compression theorem to convex surfaces
Beyond Robot Ethics: On a Legislative Consortium for Social Robotics
No full textAs robots are increasingly integrated into human society, associated problems will resemble or merge with those in other fields - we can refer to this phenomenon as the 'robot sociability problem'. In this paper, the author first analyzes the dynamic relationship between robot ethics, robotics and robot law, and then proposes a 'practical robots' approach for solving the robot sociability problem. As this approach is based on legal regulations, the author posits that a functional platform such as a 'legislative consortium for social robotics' is crucial at the initial stage for social robotics development. In conclusion, the author discusses how a legislative consortium for social robotics will be a useful approach for solving the robot sociability problem, especially emerging structural legislative problems that are related to autonomous robots.

No full textChinese Ways of Being Muslim: Negotiating Ethnicity and
Religiosity in Indonesia poses a welcoming contribution to the
intersection of Chinese and Muslim identity in Indonesia. Both identity
expressions were restricted during the New Order regime and have
experienced a revival since its end in 1998. Much has been written on the
re-discovery of Chineseness, even more so on the different forms of
Islamic revival in Indonesia. However, as the author rightly identified,
the (inter)- connection between the two has been neglected. Wei Weng
shows in his book that Chinese and Muslim identity in Indonesia have
more in common than it might appear at first sight. Both, Muslim and
Chinese identities, had been surpressed. Expressions of Islam, as well as
expressions of Chineseness, were restricted. In addition, both identites
are multiple and fluid. There is no single Chinese or Islamic identity in
Indonesia. The official national motto of Indonesia Bhinneka Tunggal
Eka (Unity in Diversity) is present everywhere. Looking further into the
similarities of Chinese and Muslim identities, Wei Weng finds that
Chineseness and Islamicness are probably the two most commodified
and visible identities in Indonesia’s markets today. Here, Rudnycsky’s
Market Islam comes to mind, and how Muslim religious ethics are
designed to merge with capitalism and consumer culture. Furthermore,
both identities carry a transnational dimension, connected to the Chinese
diaspora and the Muslim ummah. Wei Weng uses ‘Islamic ummah’,
which I find problematic because the ummah is made up of Muslims,
meaning people. However, ‘Islamic’ implies the notion of ideology,
which is problematic when refering to a community as diverse as the
Muslim ummah. To unite the two identities, the author argues tha
Book Review: Chinese Ways of Being Muslim: Negotiating Ethnicity and Religiosity in Indonesia
No full textThe title of the book, Chinese Ways of Being Muslim: Negotiating Ethnicity
and Religiosity in Indonesia itself self-explains its nature and contents. It
is a continuity of the Identiti Cina Muslim di Malaysia: Persempadanan
Perundingan dan Kacukan Budaya written by the same author, which focuses
on the identity struggle and crisis of the Chinese Muslim community in
Malaysia. Unlike the previous publication, this book has shifted from a mere
focus on cultural and identity of Chinese Muslim community into a more
comprehensive examination of all the social construction of Chinese Muslims
from different sociological, economic, political and cultural dimensions, with
a special focus on Chinese Muslim community(ies) in Indonesia.
As the author of the book, Hew Wai Weng from the Universiti
Kebangsaan Malaysia (UKM), Malaysia, asserts in its foreword that despite the
existence of signifcant literatures dealing with the issue of Chinese Muslims’
historical existence in Indonesia, especially in Java from the ffteenth and
sixteenth century, and their role in Islamic propagation, they however do not
really address the issue of cultural and politics of identity as presented in his
book. The author also acknowledges that there are also many studies on the
topic focusing specifcally on the cultural policy of the Suharto regime and
the assimilation of Chinese Muslims. On the other hand, there have also been
many studies conducted on the Chinese Muslim conversion experience and
the difculties they faced after embracing Islam. Without denying the existing
studies, research works and discussions on the issue of Chinese Muslims in
Indonesia, the author nevertheless argues that most of the works were focusing
on the elites of Chinese Muslims community(ies) in Indonesia, and neglecting
the voices of ordinary Chinese Muslims
Irish modernism and the machine
No full text"This dissertation argues that John Eglinton, James Joyce, Elizabeth Bowen, W.B. Yeats, and Samuel Beckett depict machines in texts in order to interrogate the status of Ireland's modernity. Are trains, dynamos (power generators), and bicycles signs of Ireland’s progress? Instead of an affirmation, I posit that Irish modernists issue a qualification, suggesting that Ireland’s technological development must be accompanied by ideological advancement. Irish modernists thus cast machines as vehicles that operate beyond the bounds of their mechanistic functions. These machines serve also as engines from which to lobby for Ireland’s social, cultural, and ideological progress. With this premise in mind, these writers use images of machines to: 1) envision a cosmopolitan national literary revival movement; 2) redress negative stereotypes of Ireland and Irish people as being ""backwards""; 3) reject the post-enlightenment belief in a disenchanted, merely rational world; and 4) counter traditional gender and sexual roles. In all of these instances, Irish modernists endorse outlooks that go against traditional social and cultural grains. Rather, they insist that modernization is a process that necessitates ideological, and not just technological, advancement. Moreover, Irish modernists show that it is only by pushing the boundaries of popular beliefs and practices—and not just the limits of scientific knowledge—that Ireland will embrace a modern identity that engages meaningfully with the complexities of the age."Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-05-01The student, Julie Weng, accepted the attached license on 2016-04-15 at 15:16.The student, Julie Weng, submitted this Dissertation for approval on 2016-04-18 at 09:06.This Dissertation was approved for publication on 2016-04-18 at 16:20.DSpace SAF Submission Ingestion Package generated from Vireo submission #9249 on 2016-07-07 at 14:16:49Made available in DSpace on 2016-07-07T21:14:48Z (GMT).

Design against loneliness: service design toollkit for social connectivity among the elderly
No full textLoneliness, as a social problem, has drawn wide attention of the academic and public. Moreover, loneliness among the elderly is significant. Up to 32% of adults older than age 55 report feeling lonely at any given time. Millions of euro have spent to identify the lonely elderly. With a great interest in social design, the author is intrigued by this issue and thus, initiated the project with an attempt to make a contribution to it with design methods.In the research phase, extensive literature constructed a holistic view of the loneliness and yielded a new perspective of understanding it. Loneliness is like the destination of the vicious circle between negative social interaction and negative social cognition. Moreover, it may spread through negative interaction. Thereby, the project focuses on social interaction as the entry point for intervention. Through partnering with Vierstroom, one elderly home care company who is also interested in connecting their elderly members, the project finds a context for designer’s intervention. It is activities organized by the Vierstroom and Palet welfare such as bingo game, or care lecture. Investigation of the context revealed dozens of problems and opportunities. There are five pain points highlighted in the elderly activity: the reliance of facilitator, the passive social attitude, the negative social norm, the negative complaining and the one-way communication.A new relationship between elderly and organization: sports fan and coachAnalysis and ideation provoke a vision that elderly and organization could be like sports fan and coach. With service design methods, the author paves the road to vision by seeing the activity as multiple-layers and sequential interaction. After that, a service strategy is synthesized with four steps for four sub-visions. Moreover, the strategy is translated into 15 design guidelines. Thereby, organizations could adopt the guidelines to enhance their service or generative service ideas in various cases. <br/
Computation of Weng's rank 2 zeta function over an algebraic number field
No full textAbstractIn this paper, we study the zeta function, named non-abelian zeta function, defined by Lin Weng. We can represent Weng's rank r zeta function of an algebraic number field F as the integration of the Eisenstein series over the moduli space of the semi-stable OF-lattices with rank r. For r=2, in the case of F=Q, Weng proved that it can be written by the Riemann zeta function, and Lagarias and Suzuki proved that it satisfies the Riemann hypothesis. These results were generalized by the author to imaginary quadratic fields and by Lin Weng to general number fields. This paper presents proofs of both these results. It derives a formula (first found by Weng) for Weng's rank 2 zeta functions for general number fields, and then proves the Riemann hypothesis holds for such zeta functions
