TL;DR: The study used data collected from one version of a commercial Java application for constructing a prediction model and found that an export coupling metric had the strongest association with fault-proneness, indicating a structural feature that may be symptomatic of a class with a high probability of latent faults.

TL;DR: The method is based on vector quantization, which is one of the popular image compression techniques and can achieve the following two goals: to design a high security image cryptosystem and to reduce computational complexity of the encryption and decryption algorithms.

TL;DR: The patterns described form a pattern language that can be used as a building block for a systematic view of the software development process involving DSL s.

TL;DR: The paper presents a characterization of inconsistency in software development and a framework for managing it in this context and draws upon practical experiences of dealing with inconsistency in large-scale software development projects.

TL;DR: Evaluating the performance of a CBR classifier with different parameters, namely: different distance measures, different standardization techniques, use or non-use of weights, and the number of nearest neighbors to use for the prediction indicates that there is no difference in prediction performance when using any combination of parameters.

TL;DR: The neural network approach is more appropriate for handling datasets with `smooth' trends than for Handling datasets with large fluctuations, and the training results are much better than the prediction results in general.

TL;DR: This paper provides an integrated synthesis and overview of recent studies on the proportional sampling strategy and its related work, and offers a perspective that properly interprets the results obtained so far and presents some of the interesting issues involved and new insights obtained during the course of this research.

TL;DR: The proposed model and approach provide a vehicle for global business process modeling, planning and monitoring through incorporating the time constraints, duration of activities, the duration of flow, and the activity distribution with respect to the multiple time axes into the conventional workflow processes.

TL;DR: The results of the research project in RA for enterprise integration of the IRIS group from the University Jaume I of Castellon show a framework consisting of a step by step methodology, reference models and a set of supporting tools, which will allow the creation of an Integrated Enterprise.

TL;DR: A new nonrepudiable threshold proxy signature scheme is proposed that overcomes the above weakness and is more efficient than Sun's in terms of computational complexities and communication costs.

TL;DR: An approach to modeling risk factors and simulating their effects as a means of supporting certain software development risk management activities and a tool designed specifically for therisk management activities of assessment, mitigation, contingency planning, and intervention are described.

TL;DR: A method to determine the minimum number of servers (MNS) for the critical activity such that this activity should be finished without delay for a given input arrival rate is developed and shown to be effectively utilized in practice.

TL;DR: A conservative approach and experimental results are described, based on a multi-stage reduction strategy using OO software metrics and structural properties to extract structural design patterns from OO design or C++ code.

TL;DR: In the presented study, a specific requirements management process is modelled using discrete event simulation, and the parameters of the model are estimated based on interviews with people from the specific organisation where the process is used.

TL;DR: A detailed hybrid model of a software development process currently in use at a major industrial developer is presented and it is shown how the model was used to evaluate simultaneous changes to both the process and the project environment.

TL;DR: The relationship between amount of reuse, quality, and productivity was studied using four sets of C and C++ modules collected from industrial organizations using ad hoc, black box, compositional code reuse.

TL;DR: It is proposed that much failure is due to a difference in expectations prior to the start of a new system development, and a better focus on building an understanding of the critical evaluators to develop a common understanding of expectations will improve success rates.

TL;DR: It is concluded that incentive incompatibility is inherent in the nature of software reuse for larger organizations and guidance is provided on how such organizations can design an incentive-compatible program of reuse, i.e., one that generates a climate in which developers and teams view reuse as having a more favorable "value proposition" according to the prevailing incentives operating at the team level.

TL;DR: Possibility for empirical validation of the effectiveness of the CBT module in university education are described, results of a first controlled experiment are presented and discussed, and future extensions of theCBT module towards collaborative learning environments are suggested.

TL;DR: Methods of analysis are presented which demonstrate the effects of applying various patterns on certain metric scores, and the initial conclusion being that the two approaches are indeed mainly congruent.

TL;DR: This paper analyses and evaluates the OPEN Modelling Language (OML) in terms of the Bunge–Wand–Weber model of information systems in order to define the semantics of each relevant OML construct in termsof the kind of problem-domain phenomena they are intended to represent.

TL;DR: Examination of the outcomes of a UK study of a sample of SPI programs is examined and an evaluation framework is compared that will help companies conduct a self-assessment of their readiness to undertake SPI.

TL;DR: This paper proposes a simple and secure micro-payment system which can be used for purchasing information goods on the network and achieves the authentication of the legal users, protection of the integrity of transaction messages, and prevention of duplicate spending.

TL;DR: A different approach to break the Wu's remote login authentication scheme is shown, and the modified scheme can withstand all possible attacks.

TL;DR: The combination of three traditional modelling methods, into a unique hybrid two-level modelling approach, to address software process simulation modelling issues, which can be easily customised and extended to become a tool for analysing and predicting the behaviour of actual projects.

TL;DR: Investigation of scheduling policies in a heterogeneous distributed system, where half of the total processors have double the speed of the others, indicates that each scheduling policy considered has its merits and the best performer tended to depend on the degree of multiprogramming.

TL;DR: This work presents the results obtained from a Reduced Dynamic Model developed to estimate and analyse the behaviour of SDPs in the early phases, in which there is not much information regarding the project.

TL;DR: A general implementation procedure for the industries that are interested in the application of XML/EDI is proposed and a general analysis of the technology for XML developers and observations of possible research opportunities are provided.

TL;DR: The overall System Dynamics-based simulation model of EasyWinWin is presented and details and results of the requirements elicitation component of the model are provided to assess the issues associated with the social and behavioural aspects of the Easy WinWin process and to explore how these issues affect the overall outcome of the process.
