This study develops a new approach for forecasting shear Strength of concrete beam without stirrups based on the artificial neural networks (ANN). Proposed ANN considers geometric and mechanical properties of cross section and FRP bars, and shear span-depth ratio. The ANN model is constructed from a set of experimental database available in the past literature. Efficiency of the ANN model was c...

Context: There is surprisingly little empirical software engineering research (ESER) that has analysed and reported the rich, fine-grained behaviour of phenomena over time using qualitative and quantitative data. The ESER community also increasingly recognises the need to develop theories of software engineering phenomena e.g. theories of the actual behaviour of software projects at the level o...

the vibrations produced by trains include two parts which are deterministic and random vibrations. due to variation of dynamic loads and patterns of load-time, the random vibration of moving train is one of the most important issues in the field of railway engineering. one of the important sources in producing the train vibrations is rail roughness and irregularities. in this paper, responses o...

Abstract Even though micropolar theories are widely applied for engineering applications such as the design of metamaterials, in study Earth’s interior still remain limited and particular seismology. This is due to lack understanding required elastic material parameters present theory well eigenfrequency $$\omega _r$$ ...

Software engineering education has acquired a notorious reputation for producing students that are ill-prepared for being productive in real-world software engineering settings. Although much attention has been devoted to improving the state of affairs in recent years, it still remains a difficult problem with no obvious solutions. In this paper, I attempt to discover some of the roots of the p...

The goal of this paper is to lay a foundation for rigorous empirical software engineering. I do this by introducing several theories and their models. I first present an abstract theory TM about theories and models and related processes. I then apply TM to itself, yielding MTM, a theory and model about TM. These two theories provide a unified approach to design disciplines. I then provide 4 mod...
