Semi-Trusted Mixer Based Privacy Preserving Distributed Data Mining for Resource Constrained Devices

In this paper a homomorphic privacy preserving association rule mining algorithm is proposed which can be deployed in resource constrained devices (RCD). Privacy preserved exchange of counts of itemsets among distributed mining sites is a vital part in association rule mining process. Existing cryptography based privacy preserving solutions consume lot of computation due to complex mathematical equations involved. Therefore less computation involved privacy solutions are extremely necessary to deploy mining applications in RCD. In this algorithm, a semi-trusted mixer is used to unify the counts of itemsets encrypted by all mining sites without revealing individual values. The proposed algorithm is built on with a well known communication efficient association rule mining algorithm named count distribution (CD). Security proofs along with performance analysis and comparison show the well acceptability and effectiveness of the proposed algorithm. Efficient and straightforward privacy model and satisfactory performance of the protocol promote itself among one of the initiatives in deploying data mining application in RCD.Comment: IEEE Publication format, International Journal of Computer Science and Information Security, IJCSIS, Vol. 8 No. 1, April 2010, USA.

Uniqueness theorems for meromorphic mappings sharing hyperplanes in general position

The purpose of this article is to study the uniqueness problem for meromorphic mappings from $\mathbb{C}^{n}$ into the complex projective space $\mathbb{P}^{N}(\mathbb{C}).$ By making using of the method of dealing with multiple values due to L. Yang and the technique of Dethloff-Quang-Tan respectively, we obtain two general uniqueness theorems which improve and extend some known results of meromorphic mappings sharing hyperplanes in general position.Comment: 10 page

Optimal Investment with Stopping in Finite Horizon

In this paper, we investigate dynamic optimization problems featuring both stochastic control and optimal stopping in a finite time horizon. The paper aims to develop new methodologies, which are significantly different from those of mixed dynamic optimal control and stopping problems in the existing literature, to study a manager's decision. We formulate our model to a free boundary problem of a fully nonlinear equation. Furthermore, by means of a dual transformation for the above problem, we convert the above problem to a new free boundary problem of a linear equation. Finally, we apply the theoretical results to challenging, yet practically relevant and important, risk-sensitive problems in wealth management to obtain the properties of the optimal strategy and the right time to achieve a certain level over a finite time investment horizon

Policy Coherence and Coordination for Trade Facilitation: Integrated Border Management, Single-Windows and other Options for Developing Countries

There is now increasing recognition of the critical importance of trade facilitation to further international commerce, accelerate growth, and enhance welfare if not alleviate poverty among trading nations. But there is also increasing appreciation that it is not just attention to the barriers and bottlenecks behind-the-border that are involved in trade facilitation (TF), it also calls for coherence between policies and regulations at the border and inside the border. The unavoidable participation of many government agencies and private stakeholders in border transactions calls for coordination among them towards a harmonized approach to trade facilitation. This paper discusses the need and relevance of policy coherence and coordination to facilitate trade and to what extent some trade facilitation measures (concepts) such as integrated border management and single-windows may be applicable in developing countries to improve both policy coherence and coordination.Trade Faclitation, Border trade, Policy coherence, Economic Integration

Regional Integration and Inclusive Development: Lessons from ASEAN Experience

The current economic crisis has lent extra urgency to ASEAN’s efforts at economic integration and raising its attractiveness for trade and investment. This process gained momentum in the 1990s and has made much progress, as reflected in the emergence of a wide range of extra- and intra-regional agreements. However, the effectiveness of this network of arrangements in stimulating trade and investment depends on not just the characteristics of each arrangement but how well they complement each other. This paper addresses these two areas by examining and evaluating past and present initiatives individually and collectively. Findings suggest that the fundamental impeding issues have endured over the years: lack of political will, ASEAN-style consensus-reliant negotiation, and insufficient management in implementing and harmonising of initiatives. Recommendations include agreement design innovation and focus on shared concerns to overcome lack of will, role expansion of the secretariat to monitor implementation through issuance of score cards, and establishment of specialised bodies such as sub-committees and working groups to enhance implementation and dispute settlement.ASEAN, Economic Integration, Development, Trade
