Air Traac Management (ATM) of the future allows for the possibility of free ight, in which aircraft choose their own optimal routes, altitudes, and velocities. The safe resolution of trajectory connicts between aircraft is necessary to the success of such a distributed control system. In this paper, we present a method to synthesize provably safe connict resolution maneuvers. The method models ...

heart failure is common in patients with chronic renal disease, either as a complication of renal failure or from shared risk factors, or is the major cause of death in patients on dialysis. at present, end stage renal disease (esrd) patients who have systolic heart failure are considered high-risk for surgery; and nephrologists and cardiologists are reluctant to refer these patients for kidney...

Inspired by two practical cases in Switzerland, the paper investigates a problem of elevated earth pressures downslope existing landslides. This is relevant for both permanent landslides and one-time events, particular interest area stable slope just below landslide high-pressure compression zone. Intuitively, there should be transition zone, within which high subside to far field (at rest) slo...

Forming limit curves (FLCs) are important to predict failure against biaxial deformation in sheet metal forming. Particularly crucial is the detection and evaluation of stable/instable transition which indicates necking ultimately leads rupture. In past, it has been observed that specific processes, particular free-form bending might not be predicted well by conventionally evaluated FLCs, i.e. ...

Abstract On September 5, 2019, the Veslemannen unstable rock slope (54,000 m 3 ) in Romsdalen, Western Norway, failed catastrophically after 5 years of continuous monitoring. During this period, weakened while precursor movements increased progressively, particular from 2017. Measured displacement prior to failure was around 19 upper parts instability and 4–5 toe area. The pre-failure were usua...

Nowadays, honeypots are widely used to divert attackers from the original target and keep them busy within a decoy environment. DeMilitarized Zone (DMZ) is an important zone for network administrators, because many of the services to the public network is provided at this zone. Many of the security tools such as firewalls, intrusion detection systems and several other secu...

The behavior of the web panel zone has a direct effect on cyclic performance steel moment connections. While mechanisms failure are known under load, little is about bidirectional loads in bolted Using experimental tests and calibrated numerical models, this research evaluated unidirectional loads. results showed that load can modify stress strain distribution zone. Moreover, increasing width-t...
