In this paper, we present an edge detection method based on wavelet transform and Hessian matrix of image at each pixel. Many methods which based on wavelet transform, use wavelet transform to approximate the gradient of image and detect edges by searching the modulus maximum of gradient vectors. In our scheme, we use wavelet transform to approximate Hessian matrix of image at each pixel, too. ...

This is a qualitative research study using in-depth, semi-structured interviews with CT1–ST3 trainees in trauma & orthopaedics (T&O) to characterise the factors that affect core surgical trainees’ access operating theatre for training. There were significant reported difficulties accessing among T&O our sample. The considerable service provision demands of administrative and routine daily ward ...

A game Artificial Intelligence defined by if-then rules can become hard to maintain and expand. In this paper we present a method to transform in a compact way a rule base into an And/Or Diagram, a hierarchical structure easier to manage over time. Our method is illustrated in a commercial cycling simulation video game.

The goal of theory of constraints (TOC) is to maximize output, which is achieved byidentifying and managing the critically constrained resources. To manage the constraints, Goldrattproposed five focusing steps (5FS). If we increase constrained output, the output of system will beincreased. In this paper, we focus on step four of the 5FS and use the remained capacity of nonconstraintto elevate t...
