Robust Line Planning in case of Multiple Pools and Disruptions

We consider the line planning problem in public transportation, under a robustness perspective. We present a mechanism for robust line planning in the case of multiple line pools, when the line operators have a different utility function per pool. We conduct an experimental study of our mechanism on both synthetic and real-world data that shows fast convergence to the optimum. We also explore a wide range of scenarios, varying from an arbitrary initial state (to be solved) to small disruptions in a previously optimal solution (to be recovered). Our experiments with the latter scenario show that our mechanism can be used as an online recovery scheme causing the system to re-converge to its optimum extremely fast.Comment: To appear in TAPAS 201

Facilitating independence in personal activities of daily living after a severe traumatic brain injury

This is the author's accepted manuscript. The final published article is available from the link below.Aims: This study examined the effectiveness of two components of a treatment programme typically used by occupational therapists (OTs) in personal activities of daily living (PADL) rehabilitation. Methods: A multiple baseline probe design across PADL tasks was used, one which is particularly suited to the examination of the effects of complex interventions on skill performance. The subjects were two male adults with severe brain injuries and cognitive impairments who were in the acute stages of recovery. The OT treatment program consisted of a combination of errorless learning and strategy training approaches. The impact of the program was measured by the number of steps completed independently in each of these tasks, the level and type of assistance required, and by administering the UK Functional Independence Measure and the Assessment of Motor and Process Skills. Findings: Errorless learning and strategy training, as used within an OT programme, was demonstrated to be effective in reducing the amount of assistance both participants required to complete the targeted PADL tasks. Further, there was evidence of generalization of training effects among trained and untrained activities. Conclusions: Selecting and combining treatment techniques based on detailed assessment of functional performance is an area of high clinical importance but with limited research; the current study stands as an attempt towards that direction
