Metric Trends and Evolution

چکیده
Definition Software Engineering encompasses a process, methods for managing and engineering software and tools. The role of software has undergone significant change over the past half century. From card readers to scanner, from simple equation to artificial intelligence, kilobytes to terabytes, CPU performance from 1 MHz to 6 GHz, 8 bit to 128 bit operating systems. The evolution happened in terms of space, complexity, quality and ease. Legacy applications are attributed with poor quality later with modern applications it’s eradicated. In fact the need for the evolution may even become obvious even before the new system is deployed. With evolving software, the metrics also evolved to measure the quality, not just in terms of documentation but in availability, reliability and robustness of the applications. Process and product measures have been defined to measure the quality of the engineered/developed product. The quality models and industrial standards – Six Sigma, SEI CMMI, ITIL, ISO, PMBOK, Prince2 and other, have changed the estate of software process in the IT world. Each of these help in improving the software development process. In this paper we analyze the metric evolution and the impact it has on software industry. Agile modeling is the current customer sought after model where the metrics are still evolving to suit the customer and market needs.

Assessment of the Log-Euclidean Metric Performance in Diffusion Tensor Image Segmentation
Introduction: Appropriate definition of the distance measure between diffusion tensors has a deep impact on Diffusion Tensor Image (DTI) segmentation results. The geodesic metric is the best distance measure since it yields high-quality segmentation results. However, the important problem with the geodesic metric is a high computational cost of the algorithms based on it. The main goal of this ...
متن کاملIs publication rate an equal opportunity metric?
Publication quantity is frequently used as a ranking metric for employment, promotion, and grant success, and is considered an unbiased metric for comparing applicants. However, research suggests that women publish fewer papers, such that the measure may not be equitable. We suggest reasons for the disparity, and potential future remedies. Publication quality and impact provide more equitable m...
متن کاملOn Evidence Supporting the FEAST Hypothesis and the Laws of Software Evolution
|As part of its study of the impact of feedback in the global software process on software product evolution, the FEAST/1 project has examined metric data relating to various systems in di erent application areas. High level similarities in the growth trends of the systems studied support the FEAST hypothesis. Inter alia, the results provide evidence compatible with the laws of software evoluti...

متن کاملAerobiology and the global transport of desert dust.
Desert winds aerosolize several billion tons of soil-derived dust each year, including concentrated seasonal pulses from Africa and Asia. These transoceanic and transcontinental dust events inject a large pulse of microorganisms and pollen into the atmosphere and could therefore have a role in transporting pathogens or expanding the biogeographical range of some organisms by facilitating long-d...
