A Treeboost Model for Software Effort Estimation Based on Use Case Points

Abstract: Software effort prediction is an important task in the software development life cycle. Many models including regression models, machine learning models, algorithmic models, expert judgment and estimation by analogy have been widely used to estimate software effort and cost. In this work, a Tree boost (Stochastic Gradient Boosting) model is put forward to predict software effort based on the Use Case Point method. The inputs of the model include software size in use case points, productivity and complexity. A multiple linear regression model was created and the Tree boost model was evaluated against the multiple linear regression model, as well as the use case point model by using four performance criteria: MMRE, PRED, MdMRE and MSE. Experiments show that the Tree boost model can be used with promising results to estimate software effort.

Multilayer actuators: review

Abstract: This review discusses issues related to durability and fatigue of multilayer actuator devices. Published research in the areas of processing, internal electrode configuration, and materials composition (ceramic and electrode) is discussed. The effects of humidity, temperature, and mechanical and electrical load on the lifetime of these devices are outlined. Techniques that have been developed to monitor the development of damage are also reviewed.

Equilibrium phase diagrams of isolated nano-phases

Abstract: Materials processing and fabrication shows a strong trend toward manipulation of materials at ever decreasing sizes. This is especially true in microelectronics. Once the size of a material extends...
