In this study functional magnetic resonance imaging (fMRI) was used to examine cerebral activity patterns in relation to increasing mental load of a working memory task. Aim of the experiment was to distinguish nonspecific task-related processes from specific workload processes analytically. Twelve healthy volunteers engaged in a spatial n-back task with four levels. FMRI data were acquired wit...

This paper evaluates an automatic power reduction scheme of OSCAR automatic parallelizing compiler having power reduction control capability when multiple media applications parallelized by the OSCAR compiler are executed simultaneously on RP2, a 8-core multicore processor developed by Renesas Electronics, Hitachi, and Waseda University. OSCAR compiler enables the hierarchical multigrain parall...

In this paper, in order to optimize the cell range expansion (CRE) and enhanced intercell interference coordination (eICIC) in long-term evolution advanced (LTE-A) heterogeneous cellular networks (HCNs) using multiple-input multiple-output (MIMO), a practical tessellation-based load balancing scheme is proposed, which requires little change in existing protocols. It is shown that the tessellati...

When a link fails in an IP network, the network re-converges to redirect the traffic away from the failed link. IP fast reroute is used to minimize the time taken to redirect the traffic to an alternate path. Multiple routing configurations (MRC) is the IP fast reroute scheme under consideration. In this paper, we will discuss how to minimize the impact of the MRC recovery process on the post f...

Cutting maneuvers (CM) are frequently executed in sports. This task is relevant as it is a key ability for team sports players (TSP) but also bears the risk of ACL tears. An analysis of the movement strategies (MS) and musculoskeletal loads (MSL) occurring during CMs could reveal factors for efficient CMs and major triggers governing the occurrence of ACL tears. This study investigated the MS a...

Closed form solutions for optimal finish time and job allocation are largely obtained only for network topologies with a single load originating (root) processor. However, it often happens that load can be generated from multiple sources as in large-scale data intensive problems with geographically distributed resources. This paper introduces load scheduling strategy for tree networks with two ...

This paper presents an overview of an autonomous robotic material handling system. The goal of the system is to extend the functionalities of traditional AGVs to operate in highly dynamic environments. Traditionally, the reliable functioning of AGVs relies on the availability of adequate infrastructure to support navigation. In the target environments of our system, such infrastructure is diffi...

In recent years we have seen an increasing interest in irregular topologies in the interconnect communities. The predominant routing strategy for such networks is the up*/down* algorithm proposed in connection with Autonet. One problem with this algorithm is that it creates a configuration that is very prone to hot-spots near the root of the up*/down* tree. Previous methods for handling this pr...
