Software clones are identical or similar pieces of code or design. Clones are known to be closely related to various issues on software engineering, such as software quality, complexity, architecture, refactoring, evolution, licensing, plagiarism, and so on. Various characteristics of software systems can be uncovered through the clone analysis, and system restructuring can be performed by merging clones. The purpose of this workshop is to continue to solidify and give shape to this research/application area and community. More specifically, the goals are to bring together academic and industrial researchers and practitioners from around the world to evaluate the current state of research and applications, discuss common problems, discover new opportunities for collaboration, exchange ideas, and envision new areas of research and applications. In this, the 6th international clone workshop, we will discuss issues in software clone detection, analysis and management, as well as applications to software engineering contexts that can benefit from knowledge of clones. As befits a maturing workshop, we have this year added independent program committee chairs to oversee the technical program.

The elicitation of security requirements for Software Product Lines (SPL) is a challenging task, mainly due to the varying security properties required in different products, for the diversity of market segments, and the constraint of simultaneously maintaining the cost-effective principle of the SPL paradigm. Goal-driven security requirements engineering approaches, such as Secure Tropos, have been proposed in the literature as a suitable paradigm for elicitation of security requirements and their analysis on both a social and a technical dimension. Nevertheless, on one hand, security requirements engineering methodologies are not appropriately tailored to the specific demands of SPL, while on the other hand specific proposals of SPL engineering have traditionally ignored security requirements. This paper presents work that fills this gap by proposing an extension to the Secure Tropos language to support SPL.

Study of beach morphological changes under storm conditions and its prediction capability are of paramount importance in coastal zone management. Seabed sediment is picked up violently in and outside the surf zone due to suspension mechanisms, therefore a considerable amount of sand is transported in coastal waters due to such mechanisms. For the construction of an accurate beach morphological model, it is necessary to elucidate the sediment suspension and to introduce it properly into the modelling of sediment transport. Jayaratne and Shibayama (2007) developed a complete set of explicit theoretical formulae to predict the time-averaged concentration on sandy beaches due to three suspension mechanisms: a) vortical motion over wave-generated sand ripples, b) from sheet flow, and c) turbulent motion under breaking waves. The present paper focuses on the development of a quasi-3D beach deformation model using the sediment concentration models of Jayaratne and Shibayama (2007), the bed load model of Watanabe (1982), the wave propagation model of Onaka et al. (1988), the nearshore current model of Philips (1977) and the undertow model of Okayasu et al. (1990) to predict the large-scale morphodynamics of sandy beaches. The predicted beach profiles and total sediment transport rates were compared with two sets of large-scale laboratory experimental data [Kajima et al. (1983);Kraus and Larson (1988)] and Seisho beach at Kanagawa Prefecture, Japan. It can be concluded that the present numerical model is capable of predicting sediment transport direction, on-offshore sand bar formation and the general trend of the beach profiles of large-scale erosive- and accretive-type sandy beaches to a satisfactory level.

Concurrent trace is an emerging challenge when debugging multicore systems. In concurrent trace, trace buffer becomes a bottleneck since all trace sources try to access it simultaneously. In addition, the on-chip interconnection fabric is extremely high hardware cost for the distributed trace signals. In this paper, we propose a clustering-based scheme which implements concurrent trace for debugging Network-on-Chip (NoC) based multicore systems. In the proposed scheme, a unified communication framework eliminates the requirement for interconnection fabric which is only used during debugging. With clustering scheme, multiple concurrent trace sources can access distributed trace buffer via NoC under bandwidth constraint. We evaluate the proposed scheme using Booksim and the results show the effectiveness of the proposed scheme.

Over the recent years, a number of studies in nearshore sediment transport have been researched but a greater understanding of soil-hydrodynamic interaction has still paramount importance. A series of 2D small-scale physical experiments were performed at the University of East London (UEL) hydraulics laboratory to investigate the influence of flow and sediment properties on soil scour. Measured sediment and flow data were used to develop a simple empirical relationship for scour rate of each crescent zone with the help of dimensional analysis and best-fit technique under smooth bed condition. The proposed paper discusses the extended investigation on soil-hydrodynamic behaviour by increasing the mobile bed roughness to greater values used in earlier experiments by the authors to better understand sediment particle sorting mechanism and their spreading characteristics during scour. Eventually, the proposed experimental work will lead to the comparison, calibration and development of predictive curves of scour rate for different soils of each developing crescent zones.
