TL;DR: A CMMI approach is adopted and a maturity model for SPI implementation is developed in order to guide organizations in assessing and improving their SPI implementation processes and provides a very practical structure with which to assess and improve SPI Implementation processes.

TL;DR: This paper presents a study that investigated the source of problems and issues identified during a case study at two large industrial organizations that are relevant to other, for example, comparable or less mature organizations.

TL;DR: Object-oriented design metrics concerning inheritance related measures, complexity measures, cohesion measures, coupling measures and memory allocation measures are used as the independent variables and GRNN network model is found to predict more accurately than Ward network model.

TL;DR: Problems and Programmers, an educational card game that simulates the software engineering process and is designed to teach those process issues that are not sufficiently highlighted by lectures and projects.

TL;DR: Components of a newly developed software process improvement model that aims to represent key practices in requirements engineering (RE) are presented, developed in response to practitioner needs highlighted in empirical work with UK software development companies.

TL;DR: Experimental results indicate that the proposed hybrid methods outperform the WRFM-based method and the preference-based CF method to improve the quality of recommendations.

TL;DR: A survey was conducted to discover some of the components of project outcome (in terms of personal/professional aspects as well as the project as a whole) that practitioners consider important in defining project success.

TL;DR: The evaluation results show that SPI-IF has potential to assist SPI practitioners in the design of effective SPI implementation initiatives and recommend organizations to use SPI-if in order to effectively design SPI implementation Initiatives.

TL;DR: Numerical results show that the proposed on-line adaptive software reliability prediction model using evolutionary connectionist approach based on multiple-delayed-input single-output architecture is robust across different software projects, and has a better performance with respect to next-step-predictability compared to existing neural network model for failure time prediction.

TL;DR: A software cost model that can be used to formulate realistic total software cost projects and discuss the optimal release policy based on cost and reliability considering testing effort and efficiency is proposed.

TL;DR: A set of metrics for software process models are introduced and how these can be used as maintainability indicators are discussed and the results of a family of experiments are reported that assess relationships between the structural properties, as measured by the defined metrics, of the process models and their maintainability.

TL;DR: In this article, the authors describe how to incorporate synthetic objects in a visually realistic manner in video sequences representing a real scene and discuss how the synthetic objects can be designed to conduct intelligent behavior within an augmented reality setting.

TL;DR: The number of Web pages and features/functionality provided by the application to be developed were the two most influential effort predictors for early Web cost estimation based on current practices of several Web Companies worldwide.

TL;DR: This paper focuses on the three-party authenticated key exchange protocol and proposes a new verified-based protocol to generate a session key with a weak authenticated password against guessing attacks.

TL;DR: This work adapted a survey instrument developed by Timothy Lethbridge to assess the extent to which the education delivered by four UK universities matches the requirements of the software industry, and proposes a survey methodology that it believes addresses the research question more appropriately.

TL;DR: The study has one major finding concerning the cost of the two development methods, programmer pairs and single developers become interchangeable in terms of development cost.

TL;DR: An efficient secret sharing scheme using Largrange's interpolation for generalized access structures is proposed that offers a more efficient and effective way to share multiple secrets.

TL;DR: A stochastic Petri net model of communication failure and recover behavior and a second model for the exchange of location and movement authority data packets between trains and radio block centers are presented and analyzed.

TL;DR: A software prediction model based on Markov Bayesian networks is developed, and a method to solve the network model is proposed and the use of the model is illustrated with an example.

TL;DR: A design process in which techniques for semi-automatic safety and reliability analysis of systems models are combined with multi-objective optimisation techniques to assist the gradual development of designs that can meet reliability and safety requirements and maximise profit within pragmatic development cost constraints is proposed.

TL;DR: In this article, an empirical study of the class growth and the System Design Instability (SDI) metric in two object-oriented (OO) systems, developed using an agile process similar to Extreme Programming (XP), is presented.

TL;DR: It is shown that their conditions are sufficient on M processors, under any deadline-based Pfair scheduling algorithm, if the utilization of every subset of M-1 tasks is at most one and these conditions cannot be improved upon without causing missed deadlines.

TL;DR: A new cognitive activity classification scheme is defined which has been used to record the effort expended by six student teams producing parallel implementations of the same software requirements specifications.

TL;DR: An extended Markov Bayesian network is developed to model software reliability prediction with an operational profile and is focused on discrete-time failure data.

TL;DR: A novel support vector regression based color image watermarking scheme is proposed that outperform the Kutter's method and Yu's method against different attacks including noise addition, shearing, luminance and contrast enhancement, distortion, etc.

TL;DR: The proposed design process of hyperboxes comprises of two main phases and reveals how the underlying geometry of the hyperboxes supports an immediate interpretation of software data concerning software maintenance and dealing with rules describing a number of changes made to software modules and their linkages with various software measures.

TL;DR: This paper proposes a new constant-round protocol well suited for a mobile environment and proves its security under the decisional Diffie-Hellman assumption and meets simplicity, efficiency, and all the desired security properties.

TL;DR: In this paper, the authors apply spectral methods to the software clustering problem and make comparisons to Bunch, showing that Bunch's solutions are within a known factor of the optimal solution.

TL;DR: This paper analyzes the constraints of buffer and end-to-end delay, and derive the conditions that the transcoder buffers have to meet for preventing the end decoder buffer from underflowing and overflowing, and proposes an adaptive bit rate adaptation algorithm.

TL;DR: A Software Renovation Framework (SRF) and a toolkit covering several aspects of software renovation, such as removing unused objects and code clones, and refactoring existing libraries into smaller more cohesive ones is proposed.
