The popularity of wireless local area networks (WLANs) has led to widespread deployments across different establishments. It has also translated into an increasing scale of the WLANs. Large-scale deployments made of large numbers of wireless termination points (WTPs) and covering substantial areas are increasingly common. The Wireless LAN Control Protocol (WiCoP) described in this document allo...

The IETF’s CAPWAP (Control and Provisioning of Wireless Access Points) WG has identified that a standards-based protocol is necessary between a wireless Access Controller and Wireless Termination Points (the latter are also commonly referred to as Lightweight Access Points). This specification defines the Lightweight Access Point Protocol (LWAPP), which addresses the CAPWAP’s (Control and Provi...

The foundation is the structure of lower part a building that directly related to ground or located below surface which has function bearing load other parts above it. There are various kinds dynamic capacity pile foundation, one used with field test results, namely PDA Test. purpose this research determine carrying piles using Test data then results analysis will be compared calculations Plaxi...

We propose a Split MAC (see RFC [1]) architecture based solution to enhance the quality of service (QoS) experienced by the wireless nodes in an 802.11b/e based WLAN. Our proposed solution achieves the objectives of a) providing a fair sharing of the wireless channel time among stations (STAs) while maximizing channel utilization in a situation where STAs are associated at different data rates ...

An open ended pipe pile can become plugged when sufficient frictional resistance is developed by the inner soil cylinder within the pile (soil plug), thereby preventing further intrusion of the soil into the pile. When plugging occurs in an impact driven pipe pile, a complex interaction between the pile and soil plug takes place, causing the propagating stress wave to undergo an abrupt change. ...

The standard penetration test (SPT) has been widely used because of its usability, economy, and many correlations with soil properties among other factors. In SPT, hammer energy is an important factor to evaluate and calibrate N values. To measure hammer energy, an instrumented SPT rod was developed considering that stress waves transferring on rods during SPT driving are the same as stress wav...

The dynamic load test is currently an important and usual tool for design, control, quality assurance of deep foundations. objective this paper to compare the expected geotechnical capacity through empirical semi-empirical Brazilian methods with ultimate pile obtained from interpretation Dynamic Load Tests (DLT; PDA). stress-settlement curve was constructed CAPWAP analysis blows different drop ...

Nowadays, in the civil engineering practice, the pile-building is the most universal type of foundation. It is usually associated with bridges, fly-overs and other civil engineering objects, industrial buildings, tall buildings, chimneys, tanks etc [1]. It is essential to control the quality of concrete piles. The most accepted weight-bearing capacity measurement technique is the static probe l...

Estimating pile group efficiency for open-ended steel piles in small arrangements is a challenging task designers. This paper reports on the large-scale experimental campaign performed BorWin gamma offshore converter platform, which involved single and two-pile systems scale of 1:10. The works included installation, dynamic end-of-driving tests, restrike static load tests pair groups densely co...
