Solving task planning problems involving multiple objects and robotic arms poses scalability challenges. Such involve not only coordinating high-DoF arms, but also searching through possible sequences of actions including object placements, handoffs. The current work identifies a useful connection between multi-arm rearrangement recent results in multi-body path on graphs with vertex capacity c...

Algorithms in digital signal processing (DSP) impose tight timing constraints that the compiler has to respect while considering the limited capacity of the available register files in a target DSP processor. Traditional code generation methods that schedule spill code to satisfy storage capacity may take many iterations and are usually not capable of satisfying the timing constraints. In this ...

A Gaussian MIMO broadcast channel (GMBC) models the MIMO transmission of Gaussian signals from a transmitter to one or more receivers. Its capacity region and different precoding schemes for it have been well investigated, especially for the case wherein there are only transmit power constraints. In this paper, a special case of GMBC is investigated, wherein receive power constraints are also i...

Forecast growth in e-commerce home-delivery demand provides retailers with opportunities for expansion and increased levels of investment. To maximise these opportunities, face operational logistical challenges related to order fulfilment the last mile. In contrast other sectors, many grocers operate a store-based delivery model rather than separate distribution channel. Under this model, order...
