VLSI single-chip (255,223) Reed-Solomon encoder with interleaver

The invention relates to a concatenated Reed-Solomon/convolutional encoding system consisting of a Reed-Solomon outer code and a convolutional inner code for downlink telemetry in space missions, and more particularly to a Reed-Solomon encoder with programmable interleaving of the information symbols and code correction symbols to combat error bursts in the Viterbi decoder

Affine Cartesian codes with complementary duals

A linear code $C$ with the property that $C \cap C^{\perp} = \{0 \}$ is said to be a linear complementary dual, or LCD, code. In this paper, we consider generalized affine Cartesian codes which are LCD. Generalized affine Cartesian codes arise naturally as the duals of affine Cartesian codes in the same way that generalized Reed-Solomon codes arise as duals of Reed-Solomon codes. Generalized affine Cartesian codes are evaluation codes constructed by evaluating multivariate polynomials of bounded degree at points in $m$-dimensional Cartesian set over a finite field $K$ and scaling the coordinates. The LCD property depends on the scalars used. Because Reed-Solomon codes are a special case, we obtain a characterization of those generalized Reed-Solomon codes which are LCD along with the more general result for generalized affine Cartesian codes

Translating transitional justice: the Solomon Islands Truth and Reconciliation Commission

This paper contends that although the Solomon Islands Truth and Reconciliation Commission replicated the structure and operation of a truth commission based on a globalised and placeless theory of best practice in transitional justice, it was not adequately contextualised or integrated with local approaches to reconciliation and peacebuilding and therefore fell short of its ambitious mandate. Introduction The Solomon Islands Truth and Reconciliation Commission (TRC) was the first truth commission in the Pacific, established under the Truth and Reconciliation Commission Act 2008  (TRC Act) in an effort to ‘promote national unity and reconciliation’ following the civil conflict which troubled the country between 1998 and 2003. The commission was publicly launched in 2008 by Archbishop Desmond Tutu, former Chair of the South African TRC, and officially began operations in 2010 for two years. The commission presented its five-volume final report to Prime Minister Gordon Darcy Lilo in February 2012; however, the report has yet to be publicly released or presented to parliament, despite requirements in the Act to do so. The ongoing silence of the government led to the editor of the final report, long-term Solomon Islands resident Bishop Terry Brown, unofficially releasing the report electronically in early 2013. The TRC conducted exhumations, research, closed hearings and statement taking across six of the nine provinces,  overcoming financial constraints, logistical challenges and difficult terrain. Several regional and thematic public hearings were also held and broadcast on the radio. The final report was handed over to the prime minister within the allocated two-year time frame. In light of these achievements, the Solomon Islands TRC could be considered a ‘success’ insomuch as it fulfilled its mandated duties and produced a final report — a challenging and remarkable achievement itself. This success, however, was arguably superficial, a performance of reconciliation in the theatre of post-conflict peacebuilding. A wider perspective of post-conflict peacebuilding and reconciliation in the Solomon Islands shows the TRC was a minor player on a crowded stage. Many Solomon Islanders were unaware of the TRC, and those familiar with its acronym or name were often unaware of its role or mandate. This paper contends that although the Solomon Islands TRC replicated the structure and operation of a truth commission based on a globalised and placeless theory of best practice in transitional justice, the TRC was not adequately contextualised or integrated with local approaches to reconciliation and peacebuilding and therefore fell short of its ambitious mandate. The commission did, however, produce a final report which in and of itself may serve as a positive outcome of the commission’s work. The experience of the Solomon Islands TRC demonstrates not only the conceptual and practical challenges faced and friction experienced of implementing a truth commission, but also the potential that truth commissions offer for promoting reconciliation and peacebuilding in post- conflict contexts in Melanesia. This paper is divided into six parts. First, a brief background of the Solomon Islands conflict is outlined. Second, the recent evolution of the peacebuilding and transitional justice fields are discussed to offer a background for the Solomon Islands TRC. Third, the various conflict management and reconciliation practices in Solomon Islands are outlined, leading to the fourth part which introduces and describes the background of the Solomon Islands TRC. The challenges of and failures to adapt the TRC to the local context are illustrated in the fifth part, with a discussion focused on the mistranslation of the meaning and value of both ‘truth’ and ‘reconciliation’ in post- conflict Solomon Islands. Finally, the sixth part argues that despite being initially championed by civil society actors, rather than becoming a ‘hybridised’ institution, the commission had a veneer of adaptation, and was ‘replicated’ according to normative transitional justice discourse

Labour mobility and diaspora: An overview of Solomon Islands’ historical regulatory experience, 1850s-2013

With less than 4,500 of its population of around 600,000 living overseas in 2013, the Solomon Islands ranks 138th in the world for diaspora formation. At these levels the scale of the diaspora as a proportion of population (0.8 percent) remains lower than it was in the early 20th century, when more than 5,000 Solomon islanders were compulsorily repatriated from Queensland under early Australian Commonwealth legislation. This working paper retraces and reframes the history of Solomon Islands labour mobility and diaspora formation since the 1850s, considering it in relation to the wider institutional and macro-regulatory machineries of three phases or regimes of economic, trade and mobility regulation. These regimes are referred to in this paper as: 1.liberal imperial, 2. national territorial and 3. International neoliberal. We argue that Solomon Islanders’ participation in labour mobility has been substantial under all three phases, but that international mobility and diaspora formation only developed significantly under the liberal imperial regime. Even then, however, its development proved precarious. The ways regional actors and governments acting within the different regimes have framed and segmented labour markets continue to powerfully shape mobility and diaspora outcomes. The paper concludes with a discussion of the implications of the situation to date for future economic development and security in Solomon Islands

Relative cohomology of bi-arrangements

A bi-arrangement of hyperplanes in a complex affine space is the data of two sets of hyperplanes along with a coloring information on the strata. To such a bi-arrangement, one naturally associates a relative cohomology group, that we call its motive. The motivation for studying such relative cohomology groups comes from the notion of motivic period. More generally, we suggest the systematic study of the motive of a bi-arrangement of hypersurfaces in a complex manifold. We provide combinatorial and cohomological tools to compute the structure of these motives. Our main object is the Orlik-Solomon bi-complex of a bi-arrangement, which generalizes the Orlik-Solomon algebra of an arrangement. Loosely speaking, our main result states that "the motive of an exact bi-arrangement is computed by its Orlik-Solomon bi-complex", which generalizes classical facts involving the Orlik-Solomon algebra of an arrangement. We show how this formalism allows us to explicitly compute motives arising from the study of multiple zeta values and sketch a more general application to periods of mixed Tate motives.Comment: 43 pages; minor correction

On deep holes of standard Reed-Solomon codes

Determining deep holes is an important open problem in decoding Reed-Solomon codes. It is well known that the received word is trivially a deep hole if the degree of its Lagrange interpolation polynomial equals the dimension of the Reed-Solomon code. For the standard Reed-Solomon codes $[p-1, k]_p$ with $p$ a prime, Cheng and Murray conjectured in 2007 that there is no other deep holes except the trivial ones. In this paper, we show that this conjecture is not true. In fact, we find a new class of deep holes for standard Reed-Solomon codes $[q-1, k]_q$ with $q$ a prime power of $p$. Let $q \geq 4$ and $2 \leq k\leq q-2$. We show that the received word $u$ is a deep hole if its Lagrange interpolation polynomial is the sum of monomial of degree $q-2$ and a polynomial of degree at most $k-1$. So there are at least $2(q-1)q^k$ deep holes if $k \leq q-3$.Comment: 10 pages. To appear in SCIENCE CHINA Mathematic

Invasive alien species : a threat to sustainable livelihoods in the Pacific? : an assessment of the effects of Wasmannia auropunctata (little fire ant) and Achatina fulica (giant African snail) on rural livelihoods in the Solomon Islands : a dissertation presented in fulfilment of the requirements for the degree of Doctor of Philosophy in Development Studies, Massey University, Manawatū, New Zealand

Invasive alien species (IAS) are a global phenomenon and are recognised as a driver of environmental change which can affect the well-being of people in a multitude of ways. Despite this, the role of IAS in local livelihoods has received relatively little attention. Influencing all three of the sustainable development pillars (social, economic, environmental), IAS should be recognised as a significant development issue. But they are not. As such, IAS issues are new to many sectors and governments and therefore largely go unseen and un-actioned. Contemporary rural livelihoods in the Solomon Islands are heavily reliant on subsistence/semi-subsistence agriculture. Following a livelihoods’ framework developed for the Solomon Islands, this thesis explores the influence IAS have on rural livelihoods in this country. Using two qualitative case studies, Wasmannia auropunctata (little fire ant) and Achatina fulica (giant African snail), this study investigates how vulnerable/resilient rural livelihoods are to the effects of IAS and the implications IAS have for sustainable development in the Solomon Islands. The effects of IAS on rural livelihoods are complex and at times contradictory. W. auropunctata for the most part is not negatively affecting the dominant livelihood strategy (subsistence/semi-subsistence agriculture) practised in the Solomon Islands. While there are some social impacts associated with W. auropunctata, overall Solomon Island households can be considered resilient to this IAS. Achatina fulica is a different story. This species is negatively affecting the subsistence/semi-subsistence agricultural sector on which so many rural Solomon Island households depend. This has resulted in households implementing negative livelihood diversification measures as they fail to cope or adapt to the snails’ presence. Unlike for W. auropunctata, Solomon Island households have not demonstrated any resilience to A. fulica. Understanding how rural livelihoods are affected by various stressors and adverse events can help to design development policies and interventions geared towards building better lives for all people. This can only occur however, if the full range of shocks are recognised. To date, this is not the case for IAS, and as such, they are still a significant missing component of development policy

A Distinguisher-Based Attack on a Variant of McEliece's Cryptosystem Based on Reed-Solomon Codes

Baldi et \textit{al.} proposed a variant of McEliece's cryptosystem. The main idea is to replace its permutation matrix by adding to it a rank 1 matrix. The motivation for this change is twofold: it would allow the use of codes that were shown to be insecure in the original McEliece's cryptosystem, and it would reduce the key size while keeping the same security against generic decoding attacks. The authors suggest to use generalized Reed-Solomon codes instead of Goppa codes. The public code built with this method is not anymore a generalized Reed-Solomon code. On the other hand, it contains a very large secret generalized Reed-Solomon code. In this paper we present an attack that is built upon a distinguisher which is able to identify elements of this secret code. The distinguisher is constructed by considering the code generated by component-wise products of codewords of the public code (the so-called "square code"). By using square-code dimension considerations, the initial generalized Reed-Solomon code can be recovered which permits to decode any ciphertext. A similar technique has already been successful for mounting an attack against a homomorphic encryption scheme suggested by Bogdanoc et \textit{al.}. This work can be viewed as another illustration of how a distinguisher of Reed-Solomon codes can be used to devise an attack on cryptosystems based on them.Comment: arXiv admin note: substantial text overlap with arXiv:1203.668
