Future Music Festival, Randwick, Sydney, Australia…

Right now Sydney once once again enjoyed one of the premiere Music Festivals to hit Australia – the Future Music Festival.

Randwick, in Sydney’s eastern suburbs was blasted by festival goers, and for the most portion, the crowd was not disappointed.

The fest which attracted 50,000 fans, had a line-up that ranged from Psy to alt-indie rockers The Stone Roses.

Market speak as some people questioned the use of the phrase &quotfuture music&quot for bands who had discovered fame and accomplishment decades ago, which includes The Stone Roses and The Prodigy, in spite of each acts becoming robust drawcards for several fans at the event.

There have been plenty of other hot acts on the marquee incorporated Rita Ora, Australian band The Temper Trap and Avicii.

Nicely accomplished to every person involved in the achievement of this years Future Music Festival.

FUTURE MUSIC FESTIVAL 2013 – SYDNEY
Royal Randwick Racecourse, NSW
Sat 09 Mar, 2013

AVICII
ANNOUNCED AS THE EDM HEADLINER AT THIS YEAR’S FUTURE MUSIC FESTIVAL!!

Future Entertainment can now officially confirm that chart-topping Swedish superstar and worldwide phenomenon Avicii has been added to the already monumental line-up for this year’s Future Music Festival in March!

Set to bring his enormous production to the headlining spot of the EDM stage at this year’s Future Music Festival, 2x Grammy award nominee Avicii has certainly proved himself as the EDM force to be reckoned with since he exploded on to the scene in 2011. Place fairly basically, in the comparatively quick time since we very first heard his name, Avicii has accomplished far more than most artists would dream of in an whole lifetime. And, at just 23 years of age, Avicii is just getting began!

Greatest identified for his exquisite production skills, his prolific reside performances and a string of international mega-hits like the worldwide phenomenon, ‘Levels’, (which conquered music charts worldwide racking up over 50 million YouTube views, and was declared David Guetta’s &quotTune of 2011&quot) Avicii is with no a doubt 1 of the most in demand artists on the planet.
2012 saw the Swede skyrocket. Kicking the year off with the ‘House for Hunger’ tour, Avicii and manager Ash Pournouri donated a staggering million to the organization ‘Feeding America’, by undertaking a not-for-profit 27-quit tour of the U.S.

The year also saw him headline some of the world’s greatest music festivals including Coachella, Ultra Music (exactly where he was joined on-stage by pop queen Madonna), Lollapalooza, Electric Daisy Carnival, Tomorrowland, Exit Festival, Creamfields, Mysteryland, Austin City Limits. He was also lately ranked as the second-most influential under-30 person in music by Forbes magazine.

Most not too long ago, Avicii has launched the Avicii x You project which will see him collaborate with fans, producers and musicians from all over the planet for his subsequent single. All earnings from the single will once more go to the ‘Feeding America’ charity.

2013 will see this prodigal wiz-kid join the hallowed ranks of the Future Music Festival. The Day Of The Dead-Set Great is most undoubtedly upon us and it really is set to be all the much more great with Avicii onboard!

The unstoppable force that is Avicii will headline the EDM stage at this year’s Future Music Festivals alongside fellow heavyweights Dizee Rascal, Hardwell, Steve Aoki, Madeon + several far more.

The Future Music Festival 2013 pinata has officially popped!

It’s the ‘Day Of The Dead-Set Awesome’ and this year Future Music Festival is set to rock your skulls off! We’ve been brewing anything unique, and complete of much more thoughts-blowing music than you can poke a cactus at… Future Music Festival 2013 is going to kick tougher than a Tijuana donkey on peyote! Exactly where else would you want to be? Our Casa is your casa muchacho!

With the most revolutionary and dynamic line-up to date, Future Entertainment is bringing you a curated arena and two super-sized major stages jam-packed with the hottest talent the planet has on supply.

The Prodigy will give you the Warriors Dance Arena – an entire arena dedicated to hard-edged, and heavy bass driven music plus some of the world’s most cutting-edge dub-step acts. The stage is set to showcase why this band deserves each sense of credibility and admiration attached to their name. It really is going to be large! Epic if you will. Joining them in the Warriors Dance Arena will be Boys Noize (Terminator-esque skull show! New album out this Friday), Feed Me Live (Live Teeth Show), FMF 2012 heroes Kill The Noize, Zeds Dead and Borgore. Another quite welcome addition to the Warriors Dance Arena is international tastemaker and legendary DJ in his personal right, Zane Lowe. This man has fairly actually had a hand in the shaping careers of far more than a single of the artists on this line-up and has actually earned his stripes amongst the greatest. With each and every act as illustrious and defining as the subsequent, be ready… the Warriors are coming.

Fresh from breaking records for the fastest promoting rock tour in UK history (220,000 tickets in 68 minutes!) the pioneers of option rock The Stone Roses are bringing their Manchester-borne reunion tour to Aussie shores. Joining them on the live front are fellow Brits Bloc Celebration. Returning to Australia for the very first time since the release of their critically acclaimed new album 4 they will be sending fans into an absolute frenzy as they make their debut Future Music Festival appearance.

In a move as opposed to any other, International sensation and K-Pop superstar PSY has also been added to the bill. The current on the internet obsession over his Gangnam Style video has turned the South Korean into a global phenomenon. His single has had in excess of 400 million youtube views and has reached the number 1 spot in 33 nations and counting! Arriving in Australia this Sunday, Psy will execute on X-Element and share with a captive nation his EX-PSY-TMENT about debuting his reside show at Future Music Festival 2013.

Off the back of a triumphant efficiency at the AFL Grand Final that saw their smash hit album Conditions soar back into a Best 10 position in the ARIA charts, our boys The Temper Trap will be showing the internationals how we hold our own. Adding a little a lot more Oz to the concoction will be indie-rock wunderkinds Gypsy &amp The Cat – returning with a much anticipated new album mixed by superstar Dave Fridman (The Flaming Lips, MGMT) and a new single ‘Bloom’ which shot straight to number five on the planet wide hype machine.

Anticipate items to get a tiny bonkers with UK powerhouse MC and festival should-have Dizziee Rascal back on the bill. Fellow countrymen DJ Fresh and Rudimental have also had really impressive years. With a string of hits and sold out shows to each of their names respectively, these reside acts know how to get the celebration started. Period. Also along for the ride we give you the chart-topping New York pop-rockers Fun. And you better believe it will be!

This season, Future Music Festival has pulled together an array of the finest female talent on the planet. Initial up, hailing from Harlem, we have the difficult-hitting, organic born lyricist Azealia Banks. With a considerably anticipated new album on the way, this provocative lady of the moment is all set to deliver a hot and heavy set featuring tracks from her hit EP ‘1991’. Subsequent up, Rita ‘This Is How We Do’ Ora will be taking to the stage. With no much less than 3 quantity 1 UK hits under her Alexander Wang belt and a slew of burgeoning international praise, 2013 is all about Rita’s Ora! On the topic of UK sensations, Ellie Goulding will be making her significantly-awaited Australian festival debut. Rounding off an virtually ideal female contingent are the ever-impressive Aussies (and Future Music favourites), Nervo.

If ever there was an EDM all-star line-up, to end all other line-ups, this would undoubtedly be it. FMF 2013 brings you electronic icons Steve Aoki, A-Trak (Live), Madeon and Hardwell. The EDM A-Team has officially landed.

The undisputed heavyweight champion of underground and heralded king of Ibiza, Sven V th will be bringing his Cocoon Heroes notion down below for the 1st time. Returning for his 5th performance on FMF, V th will head up the strongest techno line-up in Future Music history. We kid you not.

Korean War Memorial

Image by StarrGazr
From 1950 to 1953, the United States joined with the United Nations forces in Korea to take a stand against what was deemed a threat to democratic nations worldwide. At war’s finish, a million and a half American veterans returned to a peacetime globe of families, residences, and jobs – and to a nation long reluctant to view the Korean War as some thing to memorialize. But to the men and women who served, the Korean War could in no way be a forgotten war.
The passing of much more than four decades has brought a new viewpoint to the war and its aftermath. The time has come, in the eyes of the Nation, to set aside a location of remembrance for the men and women who served in this tough-fought war half a planet away. The Korean War Veterans Memorial honors these Americans who answered the call, these who worked and fought under the most attempting circumstances, and those who gave their lives for the trigger of freedom.

A War Half a World Away

Only 5 years had passed given that the finish of Planet War II when the United States after once more found itself embroiled in a key international conflict. In the early morning hours of June 25, 1950, the communist government of North Korea launched an attack into South Korea. Determined to assistance the world’s imperiled democracies, the United States quickly sent troops from Japan to join those currently stationed in Korea they fought with other nations below the U.N. flag. What was envisioned as a brief, decisive campaign became a prolonged, bitter, frustrating fight that threatened to explode beyond Korean borders. For 3 years the fighting raged. In 1953 an uneasy peace returned by signifies of a negotiated settlement that established a new boundary close to the original a single at the 38th parallel.
A single-and-a-half million American guys and ladies, a true cross-section of the Nation’s populace, struggled side by side in the course of the conflict. They served as soldiers, chaplains, nurses, clerks, and in a host of other combat and help roles. Many risked their lives in extraordinary acts of heroism. Of these, 131 received the Congressional Medal of Honor, the Nation’s most esteemed tribute for combat bravery.

A Spot for Reflection

Viewed from above, the memorial is a circle interesected by a triangle. Guests approaching the memorial come initial to the triangular Field of Service. Right here, a group of 19 stainless-steel statues, produced by Planet War II veteran Frank Gaylord, depicts a squad on patrol and evokes the encounter of American ground troops in Korea. Strips of granite and scrubby juniper bushes recommend the rugged Korean terrain, whilst windblown ponchos recall the harsh weather. This symbolic patrol brings with each other members of the U.S. Air Force, Army, Marines, and Navy the guys portrayed are from a range of ethnic backgrounds.
A granite curb on the north side of the statues lists the 22 nations of the United Nations that sent troops or gave medical assistance in defense of South Korea. On the south side is a black granite wall. Its polished surface mirrors the statues, intermingling the reflected photos with the faces etched into the granite. The etched mural is based on actual photographs of unidentified American soldiers, sailors, airmen, and marines. The faces represent all these who provided assistance for the ground troops. With each other these pictures reflect the determination of U.S. forces and the countless methods in which Americans answered their country’s call to duty.

The adjacent Pool of Remembrance, encircled by a grove of trees, provides a quiet setting. Numbers of those killed, wounded, missing in action, and held prisoner-of-war are etched in stone nearby. Opposite this counting of the war’s toll another granite wall bears a message inlaid in silver:
Freedom Is Not Free of charge.

Establishment and Dedication

On October 28, 1986, Congress authorized the American Battle Monuments Commission to establish a memorial in Washington, D.C., to honor members of the U.S. armed forces who served in the Korean War. The Korean War Veterans Memorial Advisory Board was appointed by President Ronald Reagan to advise a web site and design, and to raise building funds. Ground was broken in November 1993. Frank Gaylord was selected as the principal sculptor of the statues and Louis Nelson was selected to create the mural of etched faces on the wall. On July 27, 1995, the 42nd anniversary of the armistice that ended the Korean War, the memorial was devoted by President William J. Clinton and Kim Young Sam, President of the Republic of Korea.

Visiting the Memorial

The memorial is staffed from eight a.m. to midnight each and every day of the year except December 25 by park rangers who are available to answer concerns and give talks. A bookstore in the nearby Lincoln Memorial sells informational items relating to each the memorial and the Korean War.
The Korean War Veterans Memorial is element of the National Park Program, 1 of far more than 370 parks representing our nation’s natural and cultural heritage. Address inqueries to: Superintendent, National Capital Parks-Central, 900 Ohio Drive, SW, Washington, DC 20024-2000.

~1kV adjustable voltage source with sub-ppm stability

A handful of good higher precision grinding pictures I identified:

~1kV adjustable voltage source with sub-ppm stability

Image by fatllama
A industrial higher voltage source had noise and 1/f jitter that restricted its stability to .01% over almost all timescales. I wanted it to be 100 instances far better specifically over averaging occasions of .1 – 100s. I didn’t want to just add a massive RC filter, since we also require great regulation at the load and reasonable settling occasions amongst frequent switches. So, it was time to style and implement a voltage regulator. Fortunately, the circuit will have to supply barely any current the load will be the 10M of a voltage meter, and the charging currents of two electrodes amounting to 30pF of capacitance.

Here’s the simple concept: we stably divide a high voltage by one hundred and examine it to a -10V setpoint. Any errors are actively nulled by feedback to the high voltage level. Fairly a bit was inspired or shamelessly stolen from Horowitz and Hill, pp. 368-376.

A buried zener diode reference (LM399) creates a really steady ~7 V. Soon after a day of warming up, I’ve seen the fractional stability of the LM399 at least as very good as 4e-7 (1-1000 seconds). A low voltage-noise and input-offset op-amp (LT1001) converts this to ~10 V using a gain network of .2 ppm/°C Vishay resistors. The 10V is divided (more Vishay resistors) in 11 stages each stage goes to a tap on a 12-position rotary switch. This lets us pick a setpoint from amongst 11 evenly spaced voltages amongst ground and the stable 10 V reference.

The selected setpoint is RC-filtered with a polypropylene capacitor (Horowitz and Hill recommend polypropylene due to its low leakage… a alter in the leakage of .5nA would mean—heavens!—a complete ppm voltage drop in the 20kOhm filter resistance).

Meanwhile, higher voltage is applied to the the drain of an n-MOSFET featuring a very higher breakdown voltage. The supply (&quotoutput&quot) of the MOSFET is low-pass filtered with one more polypropylene capacitor (giant blue box, above), and sees a precision 100:1 voltage divider (Caddock). Certain, a voltage divider is just two stinking resistors, but the Caddock divider delivers a division ratio with really low temperature dependence and higher stability. As a result, the top resistor is made to be very Ohmic with higher voltage applied, and the two resistors are mounted on a typical heat-sunk ceramic package. They claim a ratio tempco of 5ppm/°C.

The divided output is compared with the selected setpoint by a low-noise op amp, and the amplified &quoterror&quot is sent to the gate of the MOSFET. Since the low-voltage op amp can not directly drive the high voltage pass-transistor (the gate wants to be many volts above the supply, and the supply could be at 1kV!), a second HV MOSFET acts like a voltage amplifier.

In this configuration, the MOSFETs need a bit of &quotoverhead&quot the applied HV should be about 10V higher than the &quotoutput&quot HV. And, this overhead can be produced as higher as 700 V or so ahead of the quiescent existing through the amplifier MOSFET gets to be 1mA or so.

The exterior of the box is lined with kapton-film heaters and insulation. A thermistor is buried in the aluminum and an AD590 absolute temperature sensor is mounted on the PCB subsequent to the Vishay division resistors. A temperature controller servos the box temperature to significantly greater than 1°C stability.

If you wanted to get truly fancy, the division chain and 12-position switch could be replaced with a hugely-stabilized DAC, driven by the good 10V reference here. Then, a 12-bit digital word could generate thousands of possible &quotsetpoints&quot for the HV.

Virtual Panorama of Reiter Berry Farms, in Watsonville, CA, on Thursday, August 27, 2015, are working with the U.S. Division of Agriculture (USDA) All-natural Resources Conservation Service (NRCS) to enhance on the 30% water savings they already attain with precision micro subsurface irrigation. The use of a Wireless Irrigation Monitoring Network (WIN) to collects data from wireless solar powered soil tensiometers, and climate field stations positioned throughout farms in 3 counties allow them to track soil, temperature, and humidity circumstances with a cloud-primarily based irrigation management program, to much better handle watering and soil conservation efforts in far more than 700 acres. They actively share their data, methods, and experiences with other producers. Much better management by producers using a presently dwindling provide and quality of ground water (wells) in this county will assist recharge the aquifer and avoid the migration of nearby Pacific Ocean salt water into the ground water they use. This is 1 of the approaches growers are extending the water provide. Reiter Affiliated Firms (RAC) has been involved with household farming because 1868 is a major fresh, multi-berry producer in the planet and a leading supplier of fresh strawberries, raspberries, blueberries and blackberries in North America.
Wireless soil tensiometer are buried at multiple distinct distances and depths from the subsurface water emitters and the root balls. The tensiometer measures how strongly the soil absorbs water. The tensiometer’s porous probe is buried into the soil and a pump pulls some air out, creating a vacuum. Water and moisture from the surrounding soil enters the probe. Low amounts of water entering the tensiometer indicate plants (and evaporation) are pulling water from the soil and may require to be watered. Higher levels of water entering the tensiometer indicate the plants have enough water. This data is then transmitted to a company’s cloud-based irrigation management technique that tends to make the data available on customer’s mobile device in the field. If this information is combined with historical information and other information, it can support figure out when, how extended and how fast watering requirements to be for best efficiency, soil wellness and electrical economy to increase a business’s yield and profitability. These measurements helps ensure perfect watering and for soil conservation. The farms have been using the tensiometers for five years. USDA Photo Illustration by Lance Cheung.
