This paper uses the kinematic mapping into the image space of spherical displacements to design a cooperating spherical robot system for workpiece orientating. The kinematic chain formed b y the cooperating robots grasping the workpiece forms a multi degree of freedom closed chain which is also known as a robotic mechanism. The spherical robots considered are spherical RPR open chains and they ...

Reclaimed asphalt pavement (RAP) is one of the waste materials that highway agencies promote to use in new construction or rehabilitation of highways pavement. Since the use of RAP can affect the resilient modulus and other structural properties of flexible pavement layers, this paper aims to employ two different artificial neural network (ANN) models for modeling and evaluating the effects of ...

1. Project Goals ● Develop a resilient cyber-physical control strategy for FREEDM system to secure the energy scheduling and physical operation: ○ Extending to cyber-physical security: Explore possible attacks on both energy scheduling and physical operation, analyze the impacts in terms of economic benefit and system stability. ○ Interaction between cyber/physical layer detection: Investigate ...

Motivated by problems modeling the spread of infections in networks, in this paper we explore which bipartite graphs are most resilient to widespread infections under various parameter settings. Namely, we study bipartite networks with a requirement of a minimum degree d on one side under an independent infection, independent transmission model. We completely characterize the optimal graphs in ...

We study the problem of detecting hierarchical ties in a social network by exploiting the interaction patterns between the actors (members) involved in the network. Motivated by earlier work using a rank-based approach, i.e., Rooted-PageRank, we introduce a novel timesensitive method, called T-RPR, that captures and exploits the dynamics and evolution of the interaction patterns in the network ...

the conceptualization of resilience as a general or multidimensional construct and recognizing the inhibitors and facilitators of it are the main issues in the resilience literature. therefore, the present study investigated the discriminant variables of educational resilient and emotional resilient groups in person-focused approach, to examine the general or multidimensional construct of resil...

Big cities in developing countries face many obstacles related to the built environment when confronted by socioeconomic inequalities, which is reflected uneven access basic living infrastructure, such as sanitation and housing. In light of new approaches traditional materials building techniques, this article aims investigate use digital fabrication tools production lightweight precast systems...
