![]() N bits or qubits: n bits can represent any one of 2 n possible values at any moment, while n qubits can include components corresponding to all 2 n classical states simultaneously in superposition. Indeed, one way to represent a qubit is by the polarization of a single photon of light. You could use horizontally polarized light to represent 0 and vertically polarized light to represent 1, but light can also be polarized on an angle and then has both horizontal and vertical components at once. A qubit, however, can occupy a superposition of these two information states, taking on characteristics of both. Noise can make the qubit state wander continuously from its correct location.Ī classical bit has only two possible values: 0 or 1. Other possible superpositions of 0 and 1 (described by complex numbers a and b) cover the rest of the surface. The states 0 and 1 sit at the north and south poles, and the polarization states D, A, R, and L lie on the equator. The possible states of a single isolated qubit are neatly represented on a sphere, known as a Bloch sphere. ![]() These states become fully fledged quantum bits (qubits) when they consist of pulses that each contain a single photon. Examples include the diagonal ( D) polarization at 45°, the antidiagonal ( A) at –45°, as well as right ( R) and left ( L) circularly polarized light (the imaginary number i represents a difference in phase). Light polarized at other angles has components of both H and V, representing 0 and 1 simultaneously. A classical binary digit could be represented by encoding 0 as horizontally ( H) polarized light, and 1 as vertically ( V) polarized light. Polarized light is an example of superposition. Abstract though it may seem, information always involves a physical representation, and the physics matters. This was the mantra of the distinguished IBM researcher Rolf Landauer. ![]() But before describing how we think such error correction can be made practical, we need to first review what makes a quantum computer tick. The two of us, along with many other researchers involved in quantum computing, are trying to move definitively beyond these preliminary demos of QEC so that it can be employed to build useful, large-scale quantum computers. But these experiments still have not reached the level of quality and sophistication needed to reduce the overall error rate in a system. A mature body of theory built up over the past quarter century now provides a solid theoretical foundation, and experimentalists have demonstrated dozens of proof-of-principleĮxamples of QEC. This tremendous susceptibility to errors is the single biggest problem holding back quantum computing from realizing its great promise.įortunately, an approach known as quantum error correction (QEC) can remedy this problem, at least in principle. The situation inside a quantum computer is far different: The information itself has its own idiosyncratic properties, and compared with standard digital microelectronics, state-of-the-art quantum-computer hardware is more than a billion trillion times as likely to suffer a fault. ![]() They both involve conventional, classical information, carried by hardware that is relatively immune to errors. Dates chiseled into an ancient tombstone have more in common with the data in your phone or laptop than you may realize.

One area of confusion we see fairly routinely is a boat-owner misidentifying the 1/2/B switches terminals. Basic Design Principles for Battery Switching:ġ- Bank Isolation – The ability to isolate a battery bank from both loads and charge sources in the event of a bank or battery failure.Ģ- Cross-Connection Use – The ability to use either on-board battery bank as the sole use bank, meaning it serves as starting and house load bank in an emergency, This design criteria should always include #1.ģ- Ease of Use – A battery switching design is no good if the boat owner does not understand it. Many boat owners don’t have the luxury of starting from scratch and the existing switch can usually be re-used/re-purposed easier, and in a less costly way, than converting to an entirely new switch configuration. This article is only intended to showcase how the 1/2/BOTH switch can be used in an easier and often less confusing manner. Let me be clear on this point this is not our preferred method, it is simply a method. Listed as a replacement for part #31-0000366000.Preface: I’ve seen & read many on the internet suggest that “The 1/2/BOTH is RC/Rod’s/Compass Marine’s preferred switching method”.If the ignition switch is on, the control allows the voltage to drop below 12.0 volts for approximately 5 seconds, before the solenoid is opened to insure the alternator’s full output is available for important chassis functions. This might occur when the converter is heavily loaded. If the ignition switch is off and the battery voltage drops below 12.8 volts for approximately 5 seconds, the solenoid is opened to prevent the chassis battery from being discharged by the coach loads. (normal charging voltages are from approximately 13.8 to 14.4 volts.)Īfter the solenoid has been closed, the system continuous to sense the voltage. Anytime either battery voltage goes above 13.3 volts for approximately 5 seconds, the solenoid closes. When either battery is being charged, the controller will close the isolator solenoid, connecting the two batteries together, charging them both. The Intellitec’s Bi-Directional Isolator Relay Delay – Diesel operates by sensing the voltages on both batteries. In order to use this type solenoid for continuous duty, the controller will engage it with full voltage and then reduce the coil voltage to approximately 4 volts to hold it in. To connect the two batteries together under proper conditions, it operates in combination with an intermittent duty solenoid, similar to ones used as diesel starter solenoids. The unit is housed in a plastic enclosure for mounitng in an engine compartment. The controller also senses heavy loads on either battery to prevent the wrong battery from being inadvertently discharged. If neither battery is being charged, the batteries are fully isolated. When the coach is plugged into shore power, both batteries will be charged from the converter. ![]() When the coach is being driven, both batteries will be charged from the engine’s alternator. Unlike proper systems that only allowed charging the RV battery from the engine’s alternator, the Bi-Directional Isolator Relay Delay – Diesel chargers both batteries when either one is being charged. Adding a small dash-mounted switch will allow emergency starts of diesel engines, requiring up to 800 amps of starter current. Intellitec’s Bi-Directional Isolator Relay Delay – Diesel offers a new approach to charging batteries in an RV which uses an alternator. Intellitec’s Bi-Directional Isolator Relay Delay – Diesel #00-00839-000 The one-way analysis of variance (ANOVA) is used to determine whether there are any statistically significant differences between the means of two or more independent (unrelated) groups (although you tend to only see it used when there are a minimum of three, rather than two groups). ![]() To help them out, we included all the steps to generate descriptive statistics on SPSS. We also provide help with spss service to help you in every SPSS difficulty.One-way ANOVA in SPSS Statistics Introduction Moreover, it helps the data analysts in understanding the data better.Therefore, newbies generally want to know the process of calculating descriptive statistics on SPSS. Descriptive statistics is also known as summary statistics as it summarizes the large data sets. The information about why SPSS is a great choice for performing descriptive statistics is also mention. This blog has given every information about how to do descriptive statistics on SPSS. Anyone can easily customize it with few clicks. Therefore, It is completely the choice of the user about what to display and whatnot. SPSS provides full control over the descriptive statistic. Moreover, anyone can also measure central tendency that consists of mean, median, and mode as the necessary and most popular analysis.įurthermore, Quartile, minimum, maximum, and percentile are also possible as a measure of position. SPSS provides the whole descriptive statistics analysis in numerical form.Īnyone can easily produce a measure of dispersion, i.e., standard error, variance, range, standard variance, kurtosis, and skewness. Even beginners who don’t have any knowledge of coding or statistics can comfortably use SPSS. SPSS is very easy to use for every community. Some of the reasons supporting this argument are as follows. Now, the question is why SPSS is a good choice for performing descriptive statistics. There are several software options available that can produce descriptive statistics. Why is SPSS best for Descriptive Statistics? Lastly, click on ‘OK’, and SPSS will produce the final results.

![]() To be honest, without Duke 3D doodads like calendars and stuff, it feels pretty barren. I'm not sure the office building really adds anything to the level. The bar is a nice touch as well as the end of level sequence. The opening courtyard fight works out pretty good with the trucks and all the bruisers hanging around. ![]() The forcefield trick with the two baby liquid metals was pretty cool, same with the glass wall facing the blue key room.Ī lot of really intense fights here. Except for the blue key room (depending on your actions) it's an easy level. Introduces the lost souls and pain elementals, aka the Liquid Metal stuff. Much shorter than previous levels, and a bit more conceptually intact. Favorite moment, I dunno, the whole level feels like it never lets up with monsters constantly leaking in. There's actually a lot of interesting fights here and I like the architecture, especially parts like the revenant cage room or the central room with its pillar teleporters. I take it it's an Infernal military complex. The rest of it is hide and seek among the crates with a bit of a surprise with the mancubuses in the grated room on the way to the yellow key. Really the toughest part of this map is the room that unlocks the louver doors and the open compartments right afterwards which caught me off-guard. Obligatory crate level with lots of boxes but it's actually set up quite nicely. Some of the building interiors are slightly more interesting, and I actually do enjoy the rooftop battles. There's some okay fights, only a few big outdoor ones but nothing really difficult or memorable encounter-wise. I think "Downtown" has more character than this place, but I digress. There's also a couple surprises waiting for you to lower the shield blocking the exit.īland and ugly city style level. None of the architecture really stands out but I enjoyed the teleporter swarm battle with the yellow key and the opening fight. Not too pretty but lots of action, especially the opening. And several nasty spring traps, like the first demon swarm.Ĭool techbase-style level. I have to commend excellent map flow you fight all the way to the yellow key and bam, you're right next to the yellow door. They look significantly worse than the other monsters up to this point, I think because their sprites are larger and more cohesive. The cacodemon replacements make their debut. The map is mostly outside in a badlands type area with a few indoor installations breaking things up. You have to be careful with all the hitscanners running around. This is a very hectic beginning, pretty much sprinting on eggshells. I like that the body count is starting to climb. Other than that it's a pretty standard techbase / sewer slogfest with some nice areas like the soul sphere room and several uses of deep water. Again I see that bridge layout they use to circumvent the lack of 3D floors, it's actually quite novel. Some surprises here like the only teleporter trap in the level. More techbase with of course some sewer stuff. I saw it coming but it was still a pretty rude awakening. Most memorable moment for me is the chaingun trap. Dangerous things here are the shotgunners and chaingunners. The opening is a little tense but it quickly quiets down. It's all underground, starting out in a finished installation and proceeding into darkened tunnels whose speckled nature greatly obscures the spectres. Also like the shaft secret with all the goodies. Good level, clever use of architecture for the bridge / lift. The biggest (and worse, IMO) texture offender shows up here, the garish wooden paneling that looks like a technicolor yawn. The demons look nightmarishly weird as the monster's a walking bundle of scythes. The imps don't look too terribly out of place, though they're really jerkily animated. The map is basically more of the same with some winding about. Not a lot of challenge, some chaingunners of course but the big appearances here are the imp and demon replacements. Nice big level, a few large, open rooms with very clear purposes (mess hall, slave quarters and slaughterhouse). The laser-grid doors look nice as does some of the duct work. As you explore the base, you see some goofy effects, like rockets launching in the distance, that would look have aged better were it not for the 3D-rendered sprites. You start out in a prison cell, guard murdered in front of you. Alternatively, if you’re using the software for commercial purposes, you can buy as many licenses for as many PCs as you need, and choose whether to pay the lifetime or subscription price. The lifetime license includes all the same updates as the subscription package. ![]() Wondershare Uniconverter is available as a one-off payment of $70 for a lifetime license on one PC, or as an annual subscription of $40/year on one PC. This is commercial software, so don’t go expecting it to be free. Wondershare Uniconverter doesn’t give an idea of the number of frames per second it’s converting, but the time taken was on a par with other GPU-enabled rippers such as WinX DVD Ripper Platinum (opens in new tab). ![]() The more powerful your GPU, the more assistance it’s going to be able to give to the process, and on our gaming tower PC with an Nvidia 10-series GPU the ripping process positively flew past. There is a list of supported GPUs on the Wondershare website, but it’s a pretty comprehensive list stretching back to the integrated Intel HD Graphics 2000 from 2012’s Ivy Bridge line of Intel CPUs. It doesn’t matter if you are using the built-in graphics chip in Intel or AMD’s CPUs, or have a hulking great discrete graphics card meant for gaming (both Nvidia and AMD are supported), the program can make use of it. Wondershare Uniconverter is a GPU-accelerated DVD ripper, meaning it makes use of your PC’s graphics processor to speed up the process of creating the output file. (Image credit: Wondershare) Wondershare Uniconverter review: Speed It's more feature-packed than our top pick, WinX DVD Ripper Platinum (opens in new tab), but less easy to use. Luckily, there are enough pop-up tooltips that you’re not clicking around completely in the dark, and you have to commit to your changes before the rip takes place, so you’re never in danger of ruining a perfectly good completed conversion. What all this means is that, while Uniconverter can be straightforward to use as a basic DVD Ripper, it rapidly increases in complexity when you start clicking at the small icons underneath the preview windows generated of the titles you’re about to rip. If you want to adjust the brightness and contrast, or apply a filter, to the final result, then you can do that too. If you’d rather spend some time considering exactly how large you need the output file, then you have that option. ![]() If you want to just get the disk in the drive, have it analysed by the application, then an MP4 file spat out as quickly as possible, then the program is perfectly capable of doing that. That’s because no effort has been spared in streamlining the process, enabling you to make it as complex as you like. There are some big wins for Wondershare Uniconverter in terms of how easy it is to use. ![]() ![]() We have determined that an unauthorized party gained access to portions of the LastPass development environment through a single compromised developer account and took portions of source code and some proprietary LastPass technical information.
