2013. 3.26 - 4.6. I installed small-scale solar-electric power generation system at home in Bunkyoku, Tokyo, Japan. Block diagram is

I did not install DC/AC inverter which can drive, say, notebook PC, or get smartphone recharged.
Parts are all purchased at specialized store in Akihabara district, Tokyo, Japan, whose list with prices and advertized performances is available (list). Initial investment was modest 13,000 Yen. I implemented this system to the laundry pole facing the anterior lawn garden.

On the dorsal side of the solar panel, label indicates performamce data.
Question No.1: Is this solar panel working as a unit?
I check charging voltage on a sunny day with Yokogawa Electric's circuit tester (April 7 2013).

At this moment, I noticed that the solar panel is not maximally exposed to sun shine. So I drew forth the panel more to the garden side.

Provisional judgment regarding Question No.1: The measurement of voltage of interconnects from the solar panel reflects charging voltage of this solar panel. And this cheap solar panel is working, to a greater or lesser extent.
Timer is being set "On for 1 hour after 10 minutes delay after sunset", and it is working.
Technically, solar electric generation is not so easy to let it enduring for a long time. Firstly, for battery not to run out (frequent running-out results in decrease in endurance of expensive battery), electric generation and consumption must be well balanced. Sun is not always shining, especially in Japan (this is not Arizona or Spain!). So, I will test this system step-by-step, i.e. "On time" from 1 hour after sunset, then to 2 hours, 4 hours and 8 hours, consulting battery status indicator of charge controller which shows normal/under voltage/over discharged. Future option is (1) increase of number of solar panel, (2) installation of more robust battery,,,, I hope this experiment will combine fun [pleasure] and profit, and teach me more about the reality of solar electric generation (not fantastic story, you know).
Question No.2: Is this solar panel effectively recharging the battery as a system unit?
According to nominal performance in the manual, this charging controller (Landstar LS0512R) disconnect at 11.1V and reconnect at voltage 12.6V. My thought is, probably this controller disconnects after sunset, when the charging voltage is decreasing, at 11.1V, and reconnects and begins to recharge the battery after dawn at 12.6V, when charging voltage from the panel is increasing from near zero. In this context, I suspect there is threshold voltage to start recharging the battery. If the current setting of the solar panel, e.g., efficient directly exposed area to the sun, entry angle of the sun light to the panel with seasonal variation, etc, cannot clear the reconnect voltage, this system will go purely depending on the battery without recharging by the solar electric power generation. It is certainly a possibility. In that case, 10Ah/12V battery probably has a capacity of 120W x hour. Since the output is 3W spot light, it will continue to work 120/3 = 40 hours without solar light recharging? It must be verified if this solar panel is effectively recharging. Very interesting.
2013. 4.9. I append one more solar panel of the same size. After I bring home the newly-purchased one at Akihabara (2.4 kg, +4,600 Yen), I check the charging voltage of the new one with tester in stand-alone status before installing it to the system.
The tester indicates DC 15V in dusk
O.K. no problem. At the same time, I add LED digital battery meter (voltmeter) to the battery terminals in order to health check the battery status without using tester.
DC 12.9V showed by the indicator (Camera flashlight blanks out LED reading)
I install the new panel to the system in parallel charging circuit by applying solder.
Now, timer is being re-set "On for 4 hour after 10 minutes delay after sunset"
2013. 4.11. For the last 2 days, I have checked fluctuation of the voltage of the battery with LED digital meter.
Chronological change of voltage April 9 at 19:00PM: 12.9V --(4-hour lighting)-- at 10:45PM: 12.7V --(overnight)-- April 10 at 7:00AM (a few hours of charging after sunrise): 12.9V --(daytime charging, 4-hour lighting)-- April 10 at 11:00PM:12.8V --(overnight)-- April 11 at 7:00AM (a few hours of charging after sunrise): 13.1V --(daytime charging, 2-hour lighting)-- April 11 at 19:30PM 13.0V
Now, timer is being re-set "On for 8 hour after 10 minutes delay after sunset"
2013. 4.16. Chronological change of voltage April 11 at 7:30PM 13.0V --(lighting)-- April 11 at 8:30PM: 12.7V --(lighting)-- April 12 at 7:00AM 12.7V --(daytime charging, cloudy day)-- April 12 at 6:00PM 13.1V ---(Hayama retreat)--- April 14 at 5:00PM 13.1V --(lighting)-- at 9:30PM 12.5V -- at 11.15PM 12.4V --(8-hour lighting)-- April 15 at 7:00AM 12.4V --(daytime charging)-- at 7:20PM 12.6V --(lighting)-- 10:00PM 12.4V --(8-hour lighting continued)-- April 16 at 6:30 12.3V --(daytime charging, almost sunny day)-- at 7:30PM 12.6V -- at 9:00PM 12.4V
Chronological change of voltage of the battery with LED digital meter
2013. 4.23. After the timer was re-set to "On for 8 jours" the mean voltage of the battery has been gradually lowered, and on April 21 the battery status Red LED of the charge controller began SLOWLY FLASHING, which warns "Under voltage" (If Over Discharged, the Red LED would be FAST FLASHING according to this manual). As a result, I had no other choice but to disconnect the output (lighting schedule is totally off) and to charge the battery till acceptable level. In this morning, the sun is shining after quite an absence, and the voltage level seems recovering. Charging force is remarkably different between on full sunny day and cloudy day. After moderate recovery of battery voltage, timer is re-set to "On for 1 hour" at 18:30.
I installed the second LED digital battery meter (voltmeter) to the charging line from the solar panel.
2013. 4.29. After 8-hour lighting regiment under persisting cloudy and rainy days (dark green line), I was forced to disconnect the output circuit (red line). This weekend the sky is clear and the sun is shining. As a result the battery voltage is remarkably recovered. Timer is being re-set "On for 4 hour after 10 minutes delay after sunset" again.
Battery voltage significantly recovered with shining sun (Crick to enlarge)
in this weekend

LED digital battery meter (voltmeter) of battery at 15:00 at the same time as the above image
2013. 9.29. Today the battery voltmeter indicates 13.6V and the solar panel meter 16.8V at 16:00, so timer is being re-set "On for 6 hour after 10 minutes delay after sunset".
2014. 9.23. The system is working with no problem.
2014.11.16. I added one more battery, which had been uncoupled from the Hayama system on September 22 2014, eventually to charge parallelly the two batteries (Long Deep Cycle Battery 12V10Ah).
2017.12.30. Because the original solar charge controller is malfunctioning lately, it is changed to the other el cheapo Chinese controller (2,500 Japanese Yen) - Photo-1 and Photo-2.
New solar charge controller (Crick to enlarge)
2018.1.2. Aging lighting lump (LED, right) is replaced with the new one (left) - Photo-1.
2018.8.6. I replaced the battery of Solar-Electric Power Generation at Kohinata with retired BOSCH battery (PSI-6C) which is over eleven years use on Saab S900s (1996 model) but still alive - Photo-1 Charge is made from two solar panels to the controller (middle right black box) to the left BOSCH battery (PSI-6C), - Photo-2 This time battery terminals (gold) are purchased on-line shopping at 419 Yen x 2 at MonotaRO shop.
Battery replaced to Bosch used one (Crick to enlarge)
2018.8.11. I reinstalled the till-lately incumbent two batteries, which have been disconnected temporarily for installment of Bosch battery. Now three batteries are working - Photo-1. At the same time, I installed voltmeter at the stem, in addition to the former one at the old two batteries. Be careful: when disconnecting battery, minus terminal (-) first, and when connecting, plus (+) terminal first!
2020.5.11. This system remains to be out of order for a shot period lately. I disconnect the old two Lond Deep Cycle Battery 12V10Ah (purchased in March and September 2013), and confirm that the system restored. For some time, I maitain this system only with a single Bosch battery (PSI-6C from Saab S900s, 1996 model). Separately measured, each Lond Deep battery still indicates over 10V.
2020.6.1. The cause of current malfunction is revealed exhaused battery (Long Deep Cycle WP10-12SE since 2013.3 and Bosch PSI-6C since 2006.12., both are burnt out) . I try one more car battery (Shin-Kobe Electric Machinery, originally installed to Birkin 7 on September 20 2014), which is recently retired - Photo-1.
- Retreat at Hayama, Miura Peninsula -
2013. 9.21 - 9.22. After stable system is successfully installed in Kohinata, I set up the same system again at Hayama retreat. Lighting lump (LED) is installed on the top of greenhouse here.
Solar panel (34.5x48.4x2.5 cm in dimension, 2 kg) is installed under the top of the greenhouse. Certainly, because of reflection by the top glass (roof) some degree, the yield efficiency of solar radiation energy may not be ideal, but this is my compromise in the current situation.
Controller and battery is installed to a small wooden box (caster) outside of the greenhouse, because high temperature in the greenhouse would injure the battery and controller. Ill-effect is long wiring, which may lose some electricity because of resistance. A small compact (and cheap) voltmeter is connected to the battery to monitor the voltage (to avoid over-consumption of the battery in order to elongate its endurance). Overnight, receiving the energy from the sun in the morning today, the meter indicates 12.8V, no problem. Long wiring is apparently not so problematic, so far.
After the sunset, the controller starts the LED lump - Photo-1, and actually I set up conservativly "for 2 hours after the sunset". With White Horse on the rock with Coleman's armchair. It is difficult to shoot a real image of this situation ;)
In the next morning, housing caster for battery and controller/CPU is finished after water-proof painting for the roof.
Ditto. water-proof painting for plywood roof. I assembled this temporary housing with things I have on hand.
2013.9.28. After 2-hour lighting finishes at night, the battery voltmeter indicates 12.1V and in the next noon 12.3V. Not bad, keep going.
2013.10.12-10.14. The second panel is added. Firstly it was set mobile using extension cable - Photo-1, Photo-2 (First panel is fixed at the roof of the glasshouse -red arrows- and second panel is mobile with extension cable -yellow arrows-). After searching for sweet spot/angle, the second panel is now fixed using concrete block - Photo-3, Photo-4.
2013.11.24. As the culmination altitude of the sun decreases to the winter season, the charging efficiency declines accordingly, and the voltage of the battery came down to 11.2 V this weekend. So I redeploy the second panel upward onto the wisteria trellis - Photo-1, Photo-2. Now, even the culmination is low, the panel receives photon pretty efficiently. The voltage returns to 12.5 V in the early afternoon.
2014.1.02. The roof of the small wooden caster for storage of the battery and charge controller is replaced with vinyl-chloride corrugated panel, purchased at 390Yen at the home center. The previous plywood roof was not water-resistent even after painting, and was decaying.
2014.9.22. I replaced the currently working battery (Long Deep Cycle Battery 12V10Ah), which was purchsed at the specialized shop at Akihabara circa a year ago, with dismounted car battery 40B19L from Birkin 7 after circa 4-year use - Photo-1. I suppose that the large car battery has more capacity for this kind of use, however, I don't have hard evidence or scientific data to support that hypothesis. So, I try. Otherwise, the system is working with no problem.

A ghostly transmission from outer space has been traced to a US satellite that was scraped almost half a century ago. What sounds like the log-line of the next great horror/sci-fi is actually playing out right now in the dark skies above us—and scientists aren’t sure how this space-relic could have spontaneously reactivated.
The story of LES1 is otherwise forgettable. It was the first of the Lincoln Experimental Satellite series (constructed at MIT between 1965 and 1976 under USAF sponsorship) intended to test new communication techniques in high orbit. Unfortunately, a booster failure and wiring errors sent the fledgling flier tumbling off course; after several unsuccessful efforts to maneuver LES1 back into position, it was abandoned as “space junk” in 1967. All radio transmissions ceased when onboard batteries died decades ago, making it nearly impossible to differentiate for the many thousand chunks of debris littering our orbit. And that was the end of that—of so you’d think!
In 2013, self-described “Radio Archeologist” Phil Williams from North Cornwall accidentally detected a unique and hitherto unknown satellite signal. The hobbyist went to great pains to identify the source by crosschecking lists and launch dates, finally determining that the “ghostly sounds” were absolutely emanating form LES1. The strange fluctuations in the signal are caused by surging voltage when shadows pass over the satellite’s solar panels as it rotates every 4 seconds.
So what could have caused this long-dead hunk of junk to reactivate after 47 years in the unforgiving vacuum of space? An article in Vintage News posits a theory: “It is likely that the on board batteries have now disintegrated and some other component failure has caused the transmitter on 237Mhz, to start up when it’s in sunlight.”
While this explanation sounds like mumbo-jumbo to me, it seems as good a theory as any. No doubt there are those, though, who will see much more nefarious implications in this discovery. In Independence Day, for example, the aliens embedded a signal into our communications satellites in order to coordinate a worldwide attack. While everyone knows Independence Day is pure fiction, any hint of possible alien manipulation is terrifying!
“They’re using our own satellites against us!”
You can hear the unnerving transmission for yourself below. While static is heavy, you can definitely detect a high-pitched, fluctuating tone beneath it all, like howling wind or Theremin in play. It’s the perfect soundtrack for the punishing, frozen void of outer space—extremely chilling!
What do you think about these ghostly transmission emanating from long-abandoned LES1? Technological glitch or something more ominous? Sound off in the Comments section!

Organic light-emitting diodes (OLEDs)—a thin film lighting technology—were the subject of discussion during a two-day summit held Dec. 2 and 3, 2009, in Boston. More than 100 attendees, representing a diverse audience primarily made up of lighting manufacturers and research specialists in the electronics field, along with a few lighting designers, reviewed the state of the OLED industry. For many attendees, the symposium was a chance to learn about OLEDs' potential as an illumination source: how they can be adapted for lighting technologies and the creation of luminaires.
OLEDs remain a bit of a mystery for most in the lighting industry; they often are assumed to be a different type of light-emitting diode (LED). However, participants realized over the course of the two days that this is not the case. An OLED is a diffuse, planar source; an LED is a point source. Application requirements should determine the selection of one over the other.
The 16 sessions, some just a single speaker and others a moderated panel discussion, provided a comprehensive introduction to OLED topics. Discussions included everything from market overviews to technical presentations about the types of substrate materials, as well as potential luminaire and lighting design applications.
Barry Young, managing director of the OLED Association, opened the summit with a brief market overview. In it, he indicated that by 2015 the OLED industry might be as large as $900 million. For comparison, the LED market is expected to reach $5 billion by 2013. The OLED industry is still fairly young, and people need to understand that it is not on a parallel track with the LED industry. One of Young's goals in helping to set up this summit with U.K.-based conference organizer OLEDInsider was to assess the lighting industry's understanding of OLED technology and the market.
NOT SO FAST While OLED technology has existed for several years, it is only in its second generation of development. Because of its thermal management issues, it is a fairly complex technology to create. In order to achieve a maximum output and even illumination distribution, panels sizes are still relatively limited in size—to only 6 square inches.
Nevertheless, OLEDs do offer the possibility of new lighting strategies. One of the more thought-provoking presentations was by architect Sheila Kennedy of Boston-based Kennedy & Violich Architecture. In her talk, “OLEDS: Design Beyond Bending,” Kennedy suggested that OLEDs offer “a fundamentally different kind of lighting design,” one where surfaces and objects become the focus rather than space. Kennedy also provoked with her opinion that lighting design fundamentally needs to change. It is her opinion that lighting, as it currently exists, is focused on the infrastructure needed to build and power a luminaire, not on light itself. In closing, she suggested that the times we live in belie a move to more portable devices and that we will need a variety of light sources to correspond to our daily activities. OLED technology, she says, offers a chance to do this.
WHEN WILL THE MARKET BE READY? There were a lot of technical discussions on rigid versus flexible substrates and the assembly of the OLED components themselves, but it was clear that the technology is at a critical juncture if it wants to move beyond the laboratory and begin to market deliverable products. To date, the only luminaire employing OLED technology is the Early Future OLED Lamp by designer Ingo Maurer in collaboration with Osram Opto Semiconductors—an artistic exploration of a table lamp. For this lamp, 10 OLED panels are positioned on a glass substrate, connected via metal pins to a metal spine and base. Designer Bernard Dessecker from Ingo Maurer's studio presented the lamp, acknowledging that the creation of the piece is purely an experimental exercise since the OLED panels used in it are still prohibitively expensive.
Osram Opto Semiconductors has been pushing OLED technology, and the company recently launched the Orbeos light panel in Europe. According to Osram, these panels are “market ready” for integration into lighting applications and will be available in the U.S. later this year.
Philips Lighting also has been exploring the potential of OLED technology. Kristin Knappstein, OLED unit business development manager for Philips, discussed the company's entry into the technology, Lumiblade. It currently is available in panel formations best suited for artistic explorations, the most dynamic of which is Mirrorwall, an interactive light wall of hundreds of OLED panels, which was introduced at Euroluce 2009.
There is no doubt that OLEDs offer yet another opportunity for lighting design applications. The challenge, however, will be how to make the technology available at a price point for mainstream integration.

Session description (250 word maximum in English):
Lightweight unmanned aerial vehicles (UAVs) have developed rapidly due to the miniaturization of parts and the low cost of various sensors and embedded computers and have become a popular, low-cost platform for ecological and environmental studies. This platform is especially valuable for hash environment, for example the Qinghai-Tibetan Plateau and Arctic. UAVs also have the flowing advantages: 1) high spatial and temporal resolution, when compared with satellite remote sensing; 2) high efficiency, large ground coverage and non-desctruction, when compared with ground sampling; and 3) as a bridge between stellite remote sensing and ground sampling. With these advantages, UAVs have been applied to investigate vegetation cover, biomass, patch, Yak, plateau pika, gravel and biodiversity, etc. of cold regions over the last few years.
For this session, we seek talks on the application of UAV in, but not limited to, the cold region ecology and environment, at various spatial scales, for quadrat, to plot and regional scale. Talks on the applications of UAV in permafrost and periglacial environments are especially welcame.

A series of solar storms -- flares erupting from a giant sunspot -- triggered a temporary radio blackout on Friday afternoon, October 24. According to the U.S. Space Weather Prediction Center, “This is the fourth substantial flare from this active region since Oct. 19.”
Solar flares are the most powerful eruptions on the sun. While harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, when aimed at Earth, the flares can interfere with navigation, radio and communications signals.

Vehicle-To-Everything (V2X)To make autonomous driving reality, safety and reliability targets have to be met which have to exceed human performance by magnitudes. Since autonomous vehicle will roll-out over time, a transition phase will exist in which humans and machines will operate at the same time. To avoid catastrophic accidents, the autonomous vehicles have therefore also to be reliable against human misbehavior. This requires not only sophisticated AI and computing power, but also a physical system which allows reliable communication between other vehicles and sense at the same time their environment, all in the order of milliseconds! There, the term V2X (Vehicle-To-Everything) refers to communications between different vehicles (V2V - Vehicle-To-Vehicle) as well as communications between vehicle and infrastructure (V2I - Vehicle-To-Infrastructure).
To operate reliable at day and night or in good and bad weather conditions, radar technologies have to be utilized. With a wide-transmitting beam, many objects can be targeted in one single transmission. However, due to the missing angle-accuracy, the direction of the received signal cannot be resolved. Hence narrow-beams of massive antenna-arrays have to be utilized to scan 360° of the surrounding. To achieve such a scan in milliseconds, transmissions in microseconds are needed to obtain a good enough angle-resolution of less than half a degree.
In V2V-JSAC (Joint-Sensing-And-communication) scenarios, the radar beams will also carry information from one vehicle to the other vehicle. While some of the radio-waves will bounce back from the targeted received vehicle, the transmitting vehicle can use this reflection to determine the direction and range of the targeted vehicle. Due to large bandwidths, needed to obtain position accuracy in centimeters, multiple delay paths will be resolved, which corrupt the communication and radar performance. Since MOXZ is invariant to such multipath corruptions, it will be the key-technology and enabler for V2V and especially V2X-JSAC use-cases.

Not All 1/4″ Jacks Are Created Equal
OK, here’s something I’ve seen done in at least three churches over the last few months, so I know it happens. Let’s suppose you run a standard 100 ft audio snake from the console position up to the stage. But instead of putting the amp rack up on the stage, maybe you’re using a mixing board with built-in power amps, or the amp rack is already sitting next to the console. So you look over at the audio snake and see the XLR inputs from the microphones, but there’s also two or four TRS 1/4″ jacks that look just like the 1/4″ speaker jacks on the back of your powered mixer or amplifiers.
Here’s a standard Hosa snake with 24 gauge wires for both the XLR mic inputs as well as the 1/4″ phone jack TRS returns. Looks like you can plug the TRS fanout end into the back of a power amp and passive wedge speakers into the phone jacks on the stagebox, doesn’t it? We’ll we know it sort of works, but there’s a certain amount of wattage loss from the 100 feet of 24 gauge wire instead of 100 ft of 12 gauge, which is industry recommended for this sort of speaker run.
Just how much loss will you get using 100 ft TRS 24 gauge returns instead of 12 gauge speaker wire? Glad you asked…
Let’s consider a standard situation where you have an amplifier rated with an output of 500 watts at 8 ohms, and 1,000 watts at 4 ohms. Also, let’s hang a pair of 8 ohm passive wedges on each amplifier channel which makes a load of 4 ohms. Assuming no loss in the wiring, that’s 1,000 watts coming from the amp, which splits up to 500 watts for each of the 8 ohm speakers. That’s exactly how it’s supposed to work.
Now, instead of a heavy 10 or 12 gauge gauge speaker cable, let’s substitute with our 100 ft of 24-gauge TRS returns between the amplifier and the passive speakers.
Take a look at this wire gauge resistance chart and you’ll see that 100 ft of 24-gauge copper wire has a resistance of just over 2.5 ohms. And since we have to consider that there are two legs of this wire, it adds up to 200 ft and over 5 ohms resistance in series with the speakers. For a quick review of how speaker impedance works, watch this video: http://livesoundadvice.com/sound-bytes-videos/soundbytes-speaker-impedance/
So first we start with the amplifier output. Instead of driving a 4 ohm load and producing 1,000 watts, it’s now driving a 9 ohm load, which works out to less than 500 watts (the amplifier’s 8 ohm wattage output with a 9/8 impedance factor. We now only have 430 watts coming out of the amp since it’s no longer driving an 4 ohm load. But it get’s worse. We also have to factor in a voltage divider with 5 ohms of series resistance added to a 4 ohm load. That’s 4/9 times the 430 watts of power, so we’re now down to 190 watts of power being delivered to the 4 ohm speaker load. Finally, we have to divide that 190 watts by 2 since there are two 8-ohm speakers hooked in parallel. That’s less than 100 watts being delivered to each speaker instead of the 500 watts we paid for and expected. Yikes…
That shows us that if you use a 24 gauge snake return to drive a pair of 4 ohm passive speakers, you’re throwing away 80 percent of the amplifier power you paid for. So a 1,000 watt amp is only delivering 200 watts to the speakers. Plus we’ve not even discussed how this 5 ohms of series resistance will mess with the crossover points in the speaker which can change its frequency response in a bad way adding feedback nodes.
So what to do? Well, either run a separate 12-gauge speaker wire between the power amplifiers and your passive speakers up on stage, or get something called a “Power Snake” which has 1/4″ phone jack inputs that use 14 gauge speaker wire instead of 24-gauge microphone wire. For instance, Whirlwind makes a Power Series of audio snakes for just this type of circumstance. While the 14 gauge wires will introduce a small amount of loss compared to 12 gauge wiring, the improved flexibility of the snake makes it a reasonable compromise. If you’re running a lot of power over very long runs, I still suggest 12 gauge or even 10 gauge speaker wire.
A quick look at the chart and a little math shows us that 200 ft of 14-gauge will insert only 0.5 ohms in series with the speakers, while 200 ft of 12 gauge adds up to only 0.3 ohms. Much better options with very low wattage loss.
I will admit that my first guess would have been maybe losing 20% or so of the amplifier wattage using 24-gauge twisted pair rather then 12-gauge speaker wire, but numbers don’t lie. If you use the TRS returns on a 100 ft snake to drive a pair of 8 ohm monitor wedges (or any type of passive speaker) then you will lose around 80% of the amplifier output wattage due to series insertion loss plus impedance mismatching. So buy the heavy speaker cables and get the most performance out of your sound system.
As you can see from this example, just because you can plug something into a connector on a stage, doesn’t mean you should. One of the most important things you can know is all the types of connectors you might encounter on a live sound stage, and what signal types are likely to be on them. Oh yes, and understanding the relationship between voltage, resistance, current and wattage is really helpful for figuring this sort of thing out. But more on Ohm’s Law later.

The quantum computer is no longer the stuff of science fiction. Pioneering physicists are on the brink of unlocking a new quantum universe which provides a better representation of reality than our everyday experiences and common sense ever could. The birth of quantum computers – which, like Schrödinger’s famous ‘dead and alive’ cat, rely on entities like electrons, photons or atoms existing in two states at the same time – is set to turn the computing world on its head.
In his fascinating study of this cutting-edge technology, John Gribbin updates his previous views on the nature of quantum reality, arguing for a universe of many parallel worlds where ‘everything is real’. Looking back to Alan Turing’s work on the Enigma machine and the first electronic computer, Gribbin explains how quantum theory developed to make quantum computers work in practice as well as in principle. He takes us beyond the arena of theoretical physics to explore their practical applications – from machines which learn through ‘intuition’ and trial and error to unhackable laptops and smartphones. And he investigates the potential for this extraordinary science to create a world where communication occurs faster than light and teleportation is possible.


Event producers use artificial intelligence (AI) in clever ways to increase event attendance, raise revenues, and improve attendees’ engagement.
New tech like this can seem daunting at times, but capturing it on its upswing can make or break your event. By using AI, you’re better able to data mine information about attendees. That data can then inform your production decisions, making hyper-personalization significantly easier and more effective.
Let’s talk a look at some popular uses of AI for events and learn how these are achievable in cost-effective ways.
Some interesting uses of AI for events include:
- Deep Learning: Data mining before and after events
- Biometrics for Registration and Security: Voice and Facial Recognition
- Event Support: Scheduling, Maps, Chatbots, Attendee Match-Ups, Concierge Services
First and foremost, this requires being able to effectively use an AI data-mining technique on large databases of information. Deep learning looks for patterns that are valuable to a business. AI uses machine learning to improve data mining in order to be able to predict future behavior. One way to do this work cost-effectively is to outsource the data mining for deep learning.
Deep Learning Example
An example of using deep learning effectively would be to scan all the LinkedIn profiles of current and past attendees for public events to develop a group of personas that represent typical attendees of an upcoming event being promoted.
Personas are like the characters in a story. The AI software constructs these personas from the LinkedIn profiles, and each persona represents a different type of attendee.
Some characteristics are automatically separate personas such as male versus female. However, others are subgroups under each persona such as the age of attendees. When constructing the personas, the AI software may discover patterns in the data that may not be apparent otherwise.
These identified patterns of personas are useful for a targeted marketing campaign. Marketing efforts can be focused to promote an upcoming event to those types of personas in the public who are potentially the most likely event attendees.
Evaluating the Effectiveness of Deep Learning
The return on investment in AI used for deep learning can be evaluated by comparing the cost of this deep learning effort with the revenues that come from increased attendees.
Deep learning can be applied to almost any database. Event planners can use the deep learning capabilities of AI software to learn much about event attendees of previous events to help improve the outcomes of future events.
Biometrics for Registration and Security
AI is useful in making the registration process more efficient by allowing preregistration combined with the on-site usage of biometrics for identification purposes. It can make the entire process more efficient and actually cool for once. When’s the last time someone said your registration setup was “cool”?
Using Biometrics for Registration and Security
Facial recognition makes the registration process much faster with less need for human assistance. This also enhances security at the event. Video surveillance scans of the crowd can approve the entry of the attendees as they pass through the entry doors without needing a human to check each of their badges.
Badges cannot be shared so easily with other people when facial recognition software is used. This helps eliminate the revenue loss that comes from badge sharing. This may offset some cost of this AI implementation. It also reduces the possibilities of unauthorized entry to the event space, which is a critical security issue for most events.
With biometrics, your only worry is for one of the Faceless Men to sneak into your event…
Evaluating Biometrics for Registration and Security
Adding AI facial recognition can get expensive at your event. But when you factor in the money you save from hiring more staff, you can potentially break even, if not save a good amount of cash.
Not only can this save money, but effective use of AI also increases your event’s security.
The value of this increased security can only be estimated. It is equal to the liability cost if the event security was breached by unauthorized persons with nefarious purposes.
The most helpful AI for event support comes from mobile applications. Usually, producers don’t create costly custom event mobile apps. It’s much more common to modify existing apps for specific events.
These event apps are useful when scheduling the presentations at events. They help coordinate schedule changes and notify attendees of the changes.
Event Support Examples
Interactive site maps of the event location that help attendees find things is very popular. AI-driven chatbots that are also accessible using a mobile device are helpful to answer routine questions. The AI detects patterns that emerge from the questions asked and the feedback received from users when the chatbot gives satisfactory answers. In this way, the AI chatbot continually improves its responses.
And let’s not forget about brain dates, a networking hack growing in popularity. Machine learning can match attendees with the perfect networking buddy onsite, ensuring both parties greatly benefit from the interaction.
Privacy is protected because detailed identification and the meet-up information is only given to those users that agree on both sides to meet. Concierge services help attendees with special needs at the event site and perhaps off-site needs as well.
Evaluating Event Support Effectiveness
The value of providing event support is determined by the attendees’ engagement. Some of this is financial, such as the number of attendees at optional paid-training sessions. Other effectiveness metrics are not financial but show active participation in the event by attendees. The data collected from the event support systems also serves as a data resource for future AI data mining.
At the end of the day, applying artificial intelligence to event planning is a must.
By focusing on AI implementations that have clearly-defined parameters along with ways to track performance metrics, it is possible to use AI in ways that are cost-effective. In some cases, financial performance determines the positive impact.
Other times the performance metrics may be engagement factors. These could be the number of people going to special presentations at the events. Or it could be the number of people who give positive answers to surveys about AI support systems that they use at the event.
Either way, artificial intelligence is an emerging tech producers much embrace, not ignore.

The BBC is reporting on peer-reviewed articles in Nature, which document a large frozen sea and geologically-recent volcanic activity.
The interesting part about this is that according to physicists, the reason Mars lacks a more substantial atmosphere is that its core has cooled and solidified. Such a core cannot generate the magnetic field needed to shield the atmosphere from solar wind. Unprotected, the atmosphere literally gets blown away.
But apparently “Venus has no magnetic field, perhaps because of its slow rotation.” Like earth, Venus still has a molten core. Volcanism on a planet like Mars, presumed to have a cold solid core, is a little harder to explain.
If Mars has a warmer core than anyone expects, then the absence of a magnetic field is also apparently unexplained. And since the lack of a magnetic field explains the relative lack of atmosphere, then we also don’t know why or if Mars can’t be terraformed.
