Recent studies have shown that humans effectively take into account task variance caused by intrinsic motor noise when planning fast hand movements. However, previous evidence suggests that humans have greater difficulty accounting for arbitrary forms of stochasticity in their environment, both in economic decision making and sensorimotor tasks. We hypothesized that humans can learn to optimize...

Alistair Ferguson1 Laurence C W Dixon2 Hamid Bolouri1 1 Engineering Research and Development Centre & 2 Numerical Optimisation Centre University of Hertfordshire, College Lane, Hat eld, Hertfordshire, UK Abstract RAM-based neural networks are designed to be readily and e ciently implemented in hardware. The desire to retain this property in uences the design of learning algorithms. Reverse di e...

We consider the optimal servicing of a queue with sigmoid server performance. There are various systems with sigmoid server performance including systems involving human decision making, visual perception, human-machine communication and advertising response. The tasks arrive at the server according to some stochastic process. Each task has a deadline that is incorporated as a latency penalty. ...

A closed-loop supply chain (CLSC) is the process of adding a reverse to traditional forward chain. It has positive effect on reducing environmental pollution, and therefore many governments have introduced relevant policies encourage enterprises develop CLSCs. Among them, reward–penalty policy (RPP) for recovery rate waste electrical electronic equipment (WEEE) considered better. At corporate l...

Multidimensional constrained global optimization problem with objective function under Lipschitz condition and constraints generating a feasible domain with computable boundaries is considered. For solving this problem the dimensionality reduction approach on the base of the nested optimization scheme is used. This scheme reduces initial multidimensional problem to a family of one-dimensional s...

Facing enormous pressure from the rapid growth of waste on environment and society, many developed countries have combined urban recycling systems with classification to reduce pollution recycle resources. However, this technique is not well established in developing countries. From 2000s, China has carried out projects pilot cities although they yet reach widespread success. This paper focuses...

In this paper, a novel sparsity-aware direction of arrival (DOA) estimation scheme for a noncircular source is proposed in multiple-input multiple-output (MIMO) radar. In the proposed method, the reduced-dimensional transformation technique is adopted to eliminate the redundant elements. Then, exploiting the noncircularity of signals, a joint sparsity-aware scheme based on the reweighted l1 nor...
