The mitigation of seismic-induced dynamic earth forces by placing a vertical layer of expanded polystyrene (EPS) geofoam buffer between a rigid retaining wall and the backfill soil is a recent geotechnical innovation. In this paper, the influence of an EPS geofoam buffer on the reduction of dynamic wall forces is numerically studied by simulating the results of three reduced-scale models of rig...

Fair bandwidth allocation is an important mechanism for traffic management in the Internet. Round robin schedulers, such as Deficit Round Robin (DRR), are well-suited for implementing fair queueing in multi-Gbps routers, as they schedule packets in constant time regardless of the total number of active flows. The main drawback of these schemes, however, lies in the maintenance of per flow queue...

One-atom-thick crystalline layers and their vertical heterostructures carry the promise of designer electronic materials that are unattainable by standard growth techniques. To realize their potential it is necessary to isolate them from environmental disturbances, in particular those introduced by the substrate. However, finding and characterizing suitable substrates, and minimizing the random...

Methods Heart Perfusion Protocol Male Sprague Dawley rats were anesthetized. The heart was excised, cannulated, and perfused with Krebs-Henseleit buffer equilibrated with 95% O2 5% CO2 at 370C. A water-filled latex balloon was inserted into the left ventricle and connected to a pressure transducer to record the left ventricular pressure and heart rate. The rate-pressure product (RPP) was used a...

The results of comparative DC simulation tests confirm that a proposed modification to the feedback circuit of a Flipped Voltage Follower (FVF), to produce a type of ‘Folded’ Flipped Voltage Follower (FFVF), is capable of maximising the linear DC operating range for given values of supply rail voltage and operating current.

Abstract— This paper presents a new tracking circuit design without standby leakage current issue for 2.5V/3.3V tolerant I/O buffer, which is suitable for the I/O cells in the mixedvoltage applications with different driving capabilities. One set of mixed-voltage I/O cell with the new proposed 2.5V/3.3V tolerant I/O buffer circuit has been designed and drawn in a 0.13-μm salicided CMOS process....

Many works have studied the negative impact of slow start on the performance of short transfers. Some works propose to accelerate the window increase during this phase in order to improve the performance especially on satellite links. Others propose to set the slow start threshold at the beginning of the connection to a more accurate value in order to avoid losses. But, these works didn’t accou...

Determining interdependencies and cascading failure modes in critical infrastructures is a complex problem that is exacerbated further by the diverging characteristics of the interconnected infrastructure types. Services in some types of infrastructure such as telecommunications or the electric grid are provided and consumed instantly. Others, notably oil and gas but also other infrastructures ...

An architectural technique is proposed to reduce power dissipation in conventional caches. Our technique is based on the observation of cache access locality: current access is likely to touch the same cache set including the tags as the last access. We show that considerable amount of power driving the cache tag and data banks can be saved if this cache access locality is fully exploited. This...
