We studied effects of enalaprilat and L-158,809, an angiotensin II type-1 receptor antagonist, on left ventricular (LV) diastolic relaxation in 11 normal control dogs and 16 LV hypertrophied (LVH) dogs with perinephritic hypertension. At baseline, LV systolic and end-diastolic pressures and end-systolic elastance were increased in the LVH group (all P < 0.01 vs. the control group). LV relaxatio...

A network that provides not only connectivity but also computational resources to application flows will enable a new array of network services. For example, applications that require content adaptation can be deployed more easily in a network that provides integrated communication and computational resources. In this paper, we study the problem of finding a path for a flow that has both comput...

This paper shows a 99 [g] finger joint that can exert a very strong fingertip force of more than 100 [N]. We have proposed a simple and small load-sensitive continuously variable transmission (CVT), which consists of five links and a torsion-coiled spring. The maximum fingertip force of our previous finger was limited by the mechanical strength of its links and bearings, not by the power of its...

Transmission power control in ad-hoc networks has hitherto been used only for achieving network connectivity. It has been implicitly assumed that the optimal throughput performance in ad-hoc networks can be achieved when using the minimum transmission power required to keep the network connected. However, in this paper we argue that such an assumption remains valid only under high node densitie...

In this paper, a new technology for a novel material inherent load sensor for sheet metal components of metastable austenitic steel is presented. The new technology is based on load induced martensite formation and is investigated in the Collaborative Research Centre (CRC) 653. The sensors are small areas in the sheet metal material, which have been plastically deformed by means of stamping. Du...

Traditional load shedding algorithms for data stream systems calculate current operator selectivity over several run periods and use them to determine where to shed load during the next run period. In this paper, we show that the current selectivity may change due to the implementation of load shedding. Our algorithm, called RLS, determines the optimum drop location by these changed selectivity...

The increase in real-time applications such as Voice over IP, audio and video streaming in the public Internet has warranted QoS based routing. But today’s Internet largely supports best effort traffic. Thus, a QoS routing in the best effort environment is required to support real-time applications. Flooding of some QoS attributes (e.g. available bandwidth) have been used for QoS routing. But w...

Magnetic magnesium alloys can be utilised as a load sensitive material, in which the inverse magnetostrictive effect is used in order to measure the actual loads in structural components manufactured from such lightweight sensor alloys. To achieve a material which exhibits magnetic properties, magnesium is alloyed with ferromagnetic materials like cobalt or samarium-cobalt. In order to improve ...

A person‟s cognitive state and capacity at a given moment strongly impact decision making and user experience, but are still very difficult to evaluate objectively, unobtrusively, and in real-time. Focusing on smart pen or stylus input, this paper explores features capable of detecting high cognitive load in a practical set-up. A user experiment was conducted in which participants were instruct...

Mobility nature of the mobile nodes has the most obvious problem, call drop. A handoff methodology should ensure drop rate reduction for the proper functioning of the network. Call drop may occur mainly because of the loss of signal strength when the mobile node moves away from the coverage of the base station and bandwidth starvation because of the congestion. Congestion can be handled by redu...
