Waves Licence Cloud

Via a USB Flash Drive. The easiest way to move your Waves licenses between multiple computers is to activate them on a USB flash drive. Once that's done, you will be able to run your Waves plugins on any computer to which the USB flash drive is connected. Launch Waves Central via 'Applications Waves Central'. The Waves cloud is just a place to store plugins when they are not on either the local PC or a USB stick. You don't actually run them with the licenses still on the cloud. The license must be either on USB or the local HDD.

iLok is well known amongst musicians as a piracy protection system for music software. Traditionally tied to either a USB dongle or a machine, licenses can now be delivered through iLok Cloud.

San Jose, October 17, 2017. PACE Anti-Piracy, Inc. introduces an entirely new approach to software license protection—iLok Cloud. With iLok Cloud, software publishers can offer their users quick and easy access to their licenses from any computer with an Internet connection. iLok Cloud has the same level of robust security as the current iLok USB smart key, which will remain as an option along with machine-based licenses.

Today, PACE Anti-Piracy announces the imminent launch of iLok Cloud. With iLok Cloud, software publishers that use PACE’s licensing system will have a third option to offer their users, in addition to the previously available iLok USB smart key and machine-based licenses.

Using iLok Cloud

Upon launching iLok Cloud protected software, the users will be prompted to provide their username and password. That’s it—the iLok protected software is now ready for use, without any dongles or having to use a specific authorized computer. It’s easy, iLok Cloud protected software can be used anywhere, and iLok Cloud takes the risk of lost or damaged iLok USB smart keys and computers out of the equation.

Availability

iLok Cloud will be available to software publishers as an option when updating their products in early November. Software protected with iLok Cloud should be available to end users in early 2018.

Meet PACE at AES

PACE Anti-Piracy will exhibit in booth 5040 at AES in New York City, October 18-20, 2017. We invite anyone to visit our booth where we’ll be happy to demonstrate iLok Cloud and answer any questions.

Basic theory[edit]

A fluid dynamics lab experiment illustrates flow past a mountain-shaped obstacle. Downstream wave crests radiate upwards with their group velocity pointing about 45° from horizontal. A downslope jet can be seen in the lee of the mountain, an area of lower pressure, enhanced turbulence, and periodic vertical displacement of fluid parcels. Vertical dye lines indicate effects are also felt upstream of the mountain, an area of higher pressure.

Lee waves are a form of internal gravity waves produced when stably stratified flow is forced over an obstacle. This disturbance elevates air parcels above their level of neutral buoyancy. Buoyancy restoring forces therefore act to excite vertical oscillation of the perturbed air parcels at the Brunt-Väisäla frequency, which for the atmosphere is:

$N = \sqrt{\frac{g}{θ_{0}} \frac{d θ_{0}}{d z}} {displaystyle N={sqrt {{g over theta _{0}}{dtheta _{0} over dz}}}}$ , where ${displaystyle theta _{0}(z)}$ is the vertical profile of potential temperature.

Oscillations tilted off the vertical axis at an angle of ${displaystyle phi }$ will occur at a lower frequency of ${displaystyle Ncos {phi }}$ . These air parcel oscillations occur in concert, parallel to the wave fronts (lines of constant phase). These wave fronts represent extrema in the perturbed pressure field (i.e., lines of lowest and highest pressure), while the areas between wave fronts represent extrema in the perturbed buoyancy field (i.e., areas most rapidly gaining or losing buoyancy).

Energy is transmitted along the wave fronts (parallel to air parcel oscillations), which is the direction of the wave group velocity. In contrast, the phase propagation (or phase speed) of the waves points perpendicular to energy transmission (or group velocity).^[6]^[7]

Clouds[edit]

A wave window over the Bald Eagle Valley of central Pennsylvania as seen from a glider looking north. The wind flow is from upper left to lower right. The Allegheny Front is under the left edge of the window, the rising air is at the right edge, and the distance between them is 3–4 km.

Both lee waves and the rotor may be indicated by specific wave cloud formations if there is sufficient moisture in the atmosphere, and sufficient vertical displacement to cool the air to the dew point. Waves may also form in dry air without cloud markers.^[4] Wave clouds do not move downwind as clouds usually do, but remain fixed in position relative to the obstruction that forms them.

Around the crest of the wave, adiabatic expansion cooling can form a cloud in shape of a lens (lenticularis). Multiple lenticular clouds can be stacked on top of each other if there are alternating layers of relatively dry and moist air aloft.
The rotor may generate cumulus or cumulus fractus in its upwelling portion, also known as a 'roll cloud'. The rotor cloud looks like a line of cumulus. It forms on the lee side and parallel to the ridge line. Its base is near the height of the mountain peak, though the top can extend well above the peak and can merge with the lenticular clouds above. Rotor clouds have ragged leeward edges and are dangerously turbulent.^[4]
A foehn wall cloud may exist at the lee side of the mountains, however this is not a reliable indication of the presence of lee waves.
A pileus or cap cloud, similar to a lenticular cloud, may form above the mountain or cumulus cloud generating the wave.
Adiabatic compression heating in the trough of each wave oscillation may also evaporatecumulus or stratus clouds in the airmass, creating a 'wave window' or 'Foehn gap'.

Aviation[edit]

Lee waves provide a possibility for gliders to gain altitude or fly long distances when soaring. World record wave flight performances for speed, distance or altitude have been made in the lee of the Sierra Nevada, Alps, PatagonicAndes, and Southern Alps mountain ranges.^[8] The Perlan Project is working to demonstrate the viability of climbing above the tropopause in an unpowered glider using lee waves, making the transition into stratospheric standing waves. They did this for the first time on August 30, 2006 in Argentina, climbing to an altitude of 15,460 metres (50,720 ft).^[9]^[10] The Mountain Wave Project of the Organisation Scientifique et Technique du Vol à Voile focusses on analysis and classification of lee waves and associated rotors.^[11]^[12]^[13]

The conditions favoring strong lee waves suitable for soaring are:

A gradual increase in windspeed with altitude
Wind direction within 30° of perpendicular to the mountain ridgeline
Strong low-altitude winds in a stable atmosphere
Ridgetop winds of at least 20 knots

The rotor turbulence may be harmful for other small aircraft such as balloons, hang gliders and paragliders. It can even be a hazard for large aircraft; the phenomenon is believed responsible for many aviation accidents and incidents, including the in-flight breakup of BOAC Flight 911, a Boeing 707, near Mt. Fuji, Japan in 1966, and the in-flight separation of an engine on an Evergreen International AirlinesBoeing 747 cargo jet near Anchorage, Alaska in 1993.^[14]

The rising air of the wave, which allows gliders to climb to great heights, can also result in high altitude upset in jet aircraft trying to maintain level cruising flight in lee waves. Rising, descending or turbulent air in or above the lee waves can cause overspeed or stall, resulting in mach tuck and loss of control, especially when the aircraft is operated near the 'coffin corner'.

Other varieties of atmospheric waves[edit]

Hydrostatic wave (schematic drawing)

There are a variety of distinctive types of waves which form under different atmospheric conditions.

Wind shear can also create waves. This occurs when an atmospheric inversion separates two layers with a marked difference in wind direction. If the wind encounters distortions in the inversion layer caused by thermals coming up from below, it will create significant shear waves in the lee of the distortions that can be used for soaring.^[15]

Hydraulic jump induced waves are a type of wave that forms when there exists a lower layer of air which is dense, yet thin relative to the size of the mountain. After flowing over the mountain, a type of shock wave forms at the trough of the flow, and a sharp vertical discontinuity called the hydraulic jump forms which can be several times higher than the mountain. The hydraulic jump is similar to a rotor in that it is very turbulent, yet it is not as spatially localized as a rotor. The hydraulic jump itself acts as an obstruction for the stable layer of air moving above it, thereby triggering wave. Hydraulic jumps can distinguished by their towering roll clouds, and have been observed on the Sierra Nevada range^[16] as well as mountain ranges in southern California.
Hydrostatic waves are vertically propagating waves which form over spatially large obstructions. In hydrostatic equilibrium, the pressure of a fluid can depend only on altitude, not on horizontal displacement. Hydrostatic waves get their name from the fact that they approximately obey the laws of hydrostatics, i.e. pressure amplitudes vary primarily in the vertical direction instead of the horizontal. Whereas conventional, non-hydrostatic waves are characterized by horizontal undulations of lift and sink, largely independent of altitude, hydrostatic waves are characterized by undulations of lift and sink at different altitudes over the same ground position.
Kelvin–Helmholtz instability can occur when velocity shear is present within a continuous fluid or when there is sufficient velocity difference across the interface between two fluids.
Rossby waves (or planetary waves) are large-scale motions in the atmosphere whose restoring force is the variation in Coriolis effect with latitude.
