In humanoids, a whole-body task involves the control of multiple subtasks while complying with physical constraints imposed by the robot’s structure and the external environment. To interact in realtime with the robot, we must guarantee that these constraints are fulfilled and that essential subtasks are first accomplished. In this paper, we present a hierarchical framework that focuses on two ...

The failure of critical infrastructures may be hazardous to the general population, the economy, even national security. Disruptions in one type of infrastructure often transverse to other dependent infrastructures and possibly even back to the infrastructurewhere the failure originated. Unlike previous studies, this paper proposes a newmethodwhich addresses this interdependency and the feedbac...

Our research explores how interruptive notifications support task management in a desktop environment. We conducted two user studies with a community of open source software users and developers to explore their experience with interruptive notifications. We found that certain kinds of notifications support multitasking, task prioritization, task management, as well as influence task disruption...

Currently, there are a lot of e-learning and collaborative platforms to support distance and collaborative learning, however, all of them were designed just like an application without considering the network infrastructure below. Under these circumstances when the platform is installed and runs in a campus, sometimes it has very poor performance. This paper presents a network and data link lay...

Previously learned reward values can have a pronounced impact, behaviorally and neurophysiologically, on the allocation of selective attention. All else constant, stimuli previously associated with a high value gain stronger attentional prioritization than stimuli previously associated with a low value. The N2pc, an ERP component indicative of attentional target selection, has been shown to ref...

This paper presents a review on selection and prioritization of test cases from a particular test suite. Software testing is the major process in software development life cycle. Regression testing is very costly and inevitable activity that is to be performed in a restricted environment to ensure the validity of modified software. It is inefficient to rerun every test case from test suite when...

On parallel and distributed heterogeneous computing systems, a heuristic-based task scheduling algorithm typically consists of two phases: task prioritization and processor selection. In a heuristic based task scheduling algorithm, different prioritization will produce different makespan on a heterogeneous computing system. Therefore, a good scheduling algorithm should be able to efficiently as...

The JHU HLTCOE participated in the Cold Start task in this year’s Text Analysis Conference Knowledge Base Population evaluation. This is our third year of participation in the task, and we continued our research with the KELVIN system. We submitted experimental variants that explore use of forward-chaining inference, slightly more aggressive entity clustering, refined multiple within-document c...

In this paper we compare two formulations for the kine-matic control of redundant manipulators, based on task prioritization. We also propose an incremental method to speed up the evaluation of the solution. This is especially interesting when dealing with multiple task-priority levels and with highly redundant structures. Finally, the effectiveness of the approach in the context of posture con...
