Edge Detection: A Collection of Pixel based Approach for Colored Images

The existing traditional edge detection algorithms process a single pixel on an image at a time, thereby calculating a value which shows the edge magnitude of the pixel and the edge orientation. Most of these existing algorithms convert the coloured images into gray scale before detection of edges. However, this process leads to inaccurate precision of recognized edges, thus producing false and broken edges in the image. This paper presents a profile modelling scheme for collection of pixels based on the step and ramp edges, with a view to reducing the false and broken edges present in the image. The collection of pixel scheme generated is used with the Vector Order Statistics to reduce the imprecision of recognized edges when converting from coloured to gray scale images. The Pratt Figure of Merit (PFOM) is used as a quantitative comparison between the existing traditional edge detection algorithm and the developed algorithm as a means of validation. The PFOM value obtained for the developed algorithm is 0.8480, which showed an improvement over the existing traditional edge detection algorithms.Comment: 5 Page

A constraint specification approach to building flexible workflows

Process support systems, such as workflows, are being used in a variety of domains. However, most areas of application have focused on traditional production-style processes, which are characterised by predictability and repetitiveness. Application in non-traditional domains with highly flexible process is still largely unexplored. Such flexible processes are characterised by lack of ability to completely predefine and/or an explosive number of alternatives. Accordingly we define flexibility as the ability of the process to execute on the basis of a partially defined model where the full specification is made at runtime and may be unique to each instance. In this paper, we will present an approach to building workflow models for such processes. We will present our approach in the context of a non-traditional domain for workflow, deployment, which is, degree programs in tertiary institutes. The primary motivation behind our approach is to provide the ability to model flexible processes without introducing non-standard modelling constructs. This ensures that the correctness and verification of the language is preserved. We propose to build workflow schemas from a standard set of modelling constructs and given process constraints. We identify the fundamental requirements for constraint specification and classify them into selection, termination and build constraints. We will detail the specification of these constraints in a relational model. Finally, we will demonstrate the dynamic building of instance specific workflow models on the basis of these constraints

Managing Process Variants as an Information Resource

Many business solutions provide best practice process templates, both generic as well as for specific industry sectors. However, it is often the variance from template solutions that provide organizations with intellectual capital and competitive differentiation. In this paper, we present a modeling framework that is conducive to constrained variance, by supporting user driven process adaptations. The focus of the paper is on providing a means of utilizing the adaptations effectively for process improvement through effective management of the process variants repository (PVR). In particular, we will provide deliberations towards a facility to provide query functionality for PVR that is specifically targeted for effective search and retrieval of process variants

Local capacity and resilience to flooding: community responsiveness to the community ratings system program incentives

To incentivize more community flood risks mitigation, the US Congress implemented the community rating system (CRS) in 1990. The CRS seeks to help communities build capacity to address flood risks and become more resilient to future flood disasters. Communities participating in CRS can reduce their flood risks and enjoy discounted premiums (up to 45 %) on federally required flood insurance commensurate with their community’s CRS score. A participant community is placed into one of the ten classes depending on its CRS score. Although previous research finds that the program’s structure creates opportunities for communities participating in CRS to respond to its incentives, no study has examined the characteristics of communities that changed their mitigation behavior due to this incentive scheme. In order to evaluate the performance of CRS and its tiered incentive structure, this study investigates the extent to which communities are responding strategically to CRS incentives and the characteristics of those communities behaving strategically. This study uses a regression discontinuity approach to compare the characteristics of communities above and below CRS class thresholds. The results show strategic behavior of communities participating in CRS. Communities with more information-based flood management activities, lower property values, lower flood risk, and lower population densities are more likely to respond strategically with respect to smaller CRS subsidies. For larger subsidies, the results indicate that CRS communities with higher property values are more likely to respond strategically to the policy incentives. The study concludes with a discussion of the implications of these results for the CRS program

Flood disaster management policy: An analysis of the United States Community Ratings System

Author's manuscript.In 1990 the US Federal Emergency Management Agency created the Community Ratings System (CRS) to engage local governments to enhance community flood resilience. The CRS encourages community flood risk management activities by discounting flood insurance premiums commensurate with the level of flood management measures implemented. Using a national sample of communities, this study empirically identifies factors motivating both communities’ decision to participate and intensity of participation in the CRS. The results indicate that local capacity, flood risk factors, socio-economic characteristics, and political economy factors are significant predictors of CRS participation. Further, factors predicting participation in the CRS differ from factors predicting CRS scores

Pembagian Harta Warisan Oleh Ahli Waris Pengganti Menurut Hukum Waris Islam (Analisis Putusan Pengadilan Agama Kota Malang Nomor: 958/pdt.g/2003/pa.mlg)

This study aims to determine and analyze the Religious Court Judge\u27s decision Malang in setting the substitute heirs and the right part of the inheritance based on the decision No. 958/Pdt.G/2003/PA.Mlg. Substitute heirs as referred to in Article 185 KHI, will have implications for the amount, presence and heritage quota which was originally received by other heirs. Article 174 paragraph (1) says that there are 11 people heirs, includes: father, son, brother, uncle, grandfather and widowers, mothers, daughters, sisters, grandmothers and widows. However, in relation to Article 185 KHI on the existence of substitute heirs more numerous, reaching 41 people (22 men and 19 women). But in the context of inheritance law in Indonesia, particularly the Islamic law of inheritance are not many people understood and seldom practiced correctly. This study, using descriptive analytic approach with normative juridical approach, the data collection methods of documentation based on the decision number: 958/Pdt.G/2003/PA.Mlg., And analysis of data reduction, data presentation, and draw conclusions / verification. Observing disagreements and polemics in understanding the substitute heirs and the division of inheritance based on Islamic Inheritance Law, the researchers are interested in doing research on the Division of Inheritance by Heirs Substitute According to Islamic Inheritance Law.

A Model of Dynamic Resource Allocation in Workflow Systems

Current collaborative work environments are characterized by dynamically changing organizational structures. Although there have been several efforts to refine work distribution, especially in workflow management, most literature assumes a static database approach which captures organizational roles, groups and hierarchies and implements a dynamic roles based agent assignment protocol. However, in practice only partial information may be available for organizational models, and in turn a large number of exceptions may emerge at the time of work assignment. In this paper we present an organizational model based on a policy based normative system. The model is based on a combination of an intentional logic of agency and a flexible, but computationally feasible, non-monotonic formalism (Defeasible Logic). Although this paper focuses on the model specification, the proposed approach to modelling agent societies provides a means of reasoning with partial and unpredictable information as is typical of organizational agents in workflow system
