![]() Meteorological sensor: provides atmospheric pressure and temperature data at the landing site.Impact accelerometer: The impact accelerometer was built with a range of ☑20,000 g for the large expected acceleration on impact with Mars’ surface.Its readings could “be used to derive a density profile of the Martian atmosphere” based on the acceleration data combined with knowledge of the probe's speed and ballistic coefficient. Descent accelerometer: The descent accelerometer was a commercially available sensor meant to measure accelerations from drag during descent.The probes are each equipped with five instruments to enable analysis of the atmosphere, surface, and subsurface. The two sections of the probe were designed to remain connected via a data cable. The Mars Global Surveyor would act as a relay in order to send the data collected back to Earth. The upper part of the probe, or aftbody, was designed to remain on the surface in order to transmit data through its UHF antenna to the Mars Global Surveyor spacecraft in orbit around Mars. It contained the primary science instrument on board, the Evolved Water Experiment. ![]() ![]() The lower part, called the forebody, was designed to penetrate as far as 0.6 meters (2 ft 0 in) into the soil. On impact, each shell was designed to shatter, and its grapefruit-sized probe was to punch through the soil and separate into two parts. Upon arrival near the south polar region of Mars on December 3, 1999, the basketball-sized shells were released from the main spacecraft, plummeting through the atmosphere and hitting the planet's surface at over 179 m/s (590 ft/s). They rode to Mars aboard another spacecraft, the Mars Polar Lander. The probes were launched with the Mars Polar Lander on January 3, 1999, on a Delta II 7425 Launch Vehicle.Įach probe weighed 2.4 kg (5.3 lb) and was encased in a protective aeroshell. These goals were “1) to derive the atmospheric density, pressure, and temperature throughout the entire atmospheric column, 2) to characterize the hardness of the soil and possibly the presence of layers at a scale of tens of centimeters, 3) to determine if ice is present in the subsurface soil, and, 4) to estimate the thermal conductivity of the soil at depth.” The eventual goal for such probes was to deploy networks “around a planet using no more resources than a single landing under conventional assumptions.” Though the primary objective was to validate the technology, the probes also had goals for science analysis at Mars. The penetrator concept is potentially a lower-cost approach, and has a proposed advantage of giving access to the subsurface of the planet being studied (in this case, Mars.) The Deep Space 2 mission was intended to do an engineering validation of the concept of a penetrator probe, impacting the planet at high velocity, instead of slowing down for a soft landing as done by the probes conventionally used for planetary exploration. The purpose of the program was to do high-risk technology demonstration, with a motto "Taking risks to reduce future danger." The project was led and operated by the Jet Propulsion Laboratory in Pasadena, with contributions from The University of Arizona, New Mexico State, Northern Arizona University, the Air Force Research Laboratory, and others. Overview Deep Space 2 project manager Sarah Gavit with the engineering hardware of the probeĭeep Space 2, also known as "Mars Microprobe," was the second spacecraft developed under the NASA New Millennium Program to flight-test advanced technologies concepts for space missions. The Deep Space 2 development costs were US$28 million. The mission was declared a failure on March 13, 2000, after all attempts to reestablish communications following the descent went unanswered. Intended to be the first spacecraft to penetrate below the surface of another planet, after entering the Mars atmosphere DS2 was to detach from the Mars Polar Lander mother ship and plummet to the surface using only an aeroshell impactor, with no parachute. The probes were named "Scott" and "Amundsen", in honor of Robert Falcon Scott and Roald Amundsen, the first explorers to reach the Earth's South Pole. It included two highly advanced miniature space probes that were sent to Mars aboard the Mars Polar Lander in January 1999.

Far from seeming burdened by her legacy, the Susanna Clarke we encounter here might be an unusually gifted newcomer unacquainted with her namesake’s work. The result is a remarkable feat, not just of craft but of reinvention. Clarke fuses these themes, seducing us with imaginative grandeur only to sweep that vision away, revealing the monstrosities to which we can not only succumb but wholly surrender ourselves. Goethe, it is said, was so taken with these that he found the real Rome to be greatly disappointing. The historical Piranesi, an 18th-century engraver, is celebrated for his intricate and oppressive visions of imaginary prisons and for his veduta ideate, precise renderings of classical edifices set amid fantastic vistas. Here it is worth reflecting on the subject of Clarke’s overt homage. What can be said, though, is that at least the contours of the truth are encoded in this novel’s architecture. It would be a disservice even to hint at the revelations that follow, revelations that not only upend Piranesi’s world but confront the reader with some truly onerous moral uncertainties. ![]() Enthralled, he relates the news to the Other, whose habitual cold indifference gives way to stern warnings: Piranesi must keep away from this other person at all costs his very sanity could be in danger. These begin when he finds signs of another visitor to the House. The various items – multivitamins, a sleeping bag, plastic bowls – are as incongruous in this setting as the “shining device” that the Other carries, but it takes more momentous events to disturb Piranesi’s obliviousness. So too does his abject gratitude for the Other’s occasional gifts. ![]() These moments are touching, though related with affectless decorum, but Piranesi’s peculiar equanimity comes to seem unsettling. He wonders, too, about the identities of the dead, but subsumes even these pressing questions into acts of tranquil devotion, bringing offerings of water lilies to the forlorn remains of “the Folded-Up Child”. Piranesi does evince at least some curiosity, not least about who he really is he was given that name by the Other and cannot remember his own. ![]() He documents with satisfaction – and with no trace of despair – how he has sustained himself with meagre catches of fish and staved off the cold by burning dried seaweed. He wanders empty halls and courtyards, cataloguing in his meticulous journal entries their bewildering array of statuary. Its narrator, though deprived of both company and reliable memories, seems curiously content with his lot. And where Jonathan Strange was populous and richly polyphonic, Piranesi is a tenebrous study in solitude. All that has been cast aside here, in favour of a prose that is economical almost to the point of austerity. This is, for a start, a much shorter novel than its predecessor, whose doorstopper proportions were a byproduct of its garrulous and vastly digressive style. Some distinguishing features are immediately apparent. Does it announce an author boldly reclaiming her territory, or one emerging from her own shadow? Well, it’s complicated. And, given the long silence that followed, even non-devotees might wonder what to expect of this new novel. The Ladies of Grace Adieu, a collection of stories published in 2006, was politely received by critics but didn’t quite rekindle the fervour of devotees. Yet even as her imitators proliferated, she herself returned only briefly to her antic and ornate parallel Regency. Like Hilary Mantel, Clarke made the very notion of genre seem quaint. Infusing “great tradition” verisimilitude with the imaginative radicalism of Ursula Le Guin, it gave rise to what might be called magical archaism, a fictional strain that has since become widespread. But its lingering influence – perhaps all the more notable for her long quiescence – has not been fully appreciated. ![]() She is hardly obscure, of course her first novel, Jonathan Strange & Mr Norrell, became a worldwide bestseller and was given a plush TV adaptation by the BBC. Susanna Clarke is a writer who has never quite been given her due. 2/23/2024 0 Comments Git undo pushed commit![]() The notation refers to a numbered entry in the reflog for branch in this case HEAD, the current branch. The reflog shows the sequence of operations performed: commit, pull, checkout, merge, etc. For example : $ git log -gĮ674ab77 commit (amend): Digital Restrictioâ¦ĩ65dfda4 commit: Digital Rights Managementĭ77b78fa checkout: moving from sol to masterĢee20b94 pull: Merge made by the 'recursiveâ¦ĭ77b78fa checkout: moving from master to sol git log -g displays a composite reflog, starting with the current branch and chaining back through commands that switch branches, such as git checkout. For each branch, Git maintains a log of operations performed while on that branch, called its âreflog.â Recall that a branch is just a ref pointing to the tip commit of the branch each ref can have a log recording its referents over time. The -g option shows something entirely different, however. The git log command, which we will discuss in Chapter 9, normally shows the history of your project via portions of the commit graph. Git has a feature to save you, though, called the reflog: $ git log -g You would appear to be out of luck: that commit has been discarded, and unless you happen to have its object ID, you have no way to refer to it, even though itâs still in the object database. Suppose youâre having an off day and, having committed and then amended that commit, you suddenly realize that you just lost some information from the first commit that you didnât mean to. So you simply modify the index as desired, and commit again.Īlthough we described it in terms of a linear history, git commit -amend works with merge commits as well then there are multiple parents and branches involved instead of just one, but it operates analogously. Having dropped the previous commit, the repository state you want to change and re-commit would appear to be lostâ¦but no: thereâs another copy of it in the index, since that commit was made from the current index. Eventually, if the discarded commit remains disconnected from the commit graph, Git will delete it from the object database as part of periodic garbage collection. Thus, discarding the tip commit consists only of moving the branch pointer backward to the previous one nothing else need be done. In particular, no commits point to this one, so no other commits are affected (recall that commits point to their parents, but not to their children). The tip commit on the current branch has a pointer to the previous commit, its parent that is all that links it to the rest of the branch. The -amend feature is a good example of how Gitâs internal organization makes many operations very easy, both to implement and to understand. You can add -C HEAD if you want to reuse the previous commit message as-is. Git will present you with the previous commit message to edit if you like then, it simply discards the previous commit and puts a new one in its place, with your corrections. Then use this command : $ git commit -amend Thereâs no preparatory step just make whatever corrections you need, adding these to the index as usual. This common situation is also the easiest one to address. ![]() ![]() ![]() The most common correction to make is to the previous commit: you run git commit, and then realize you made a mistakeâperhaps you forgot to include a new file, or left out some comments. We will discuss techniques for editing a branched history in Chapter 10. Note that most of the techniques discussed in this chapter only make sense when the portion of history involved is linear that is, contains no merge commits. The extra step afforded by Git is crucial, though: by separating committing and publishing, it allows you to use version control freely for your own purposes as you work, then clean up your commits for public consumption before publishing them. You are free to delete or change your local commits as you please, and Git gives you the tools to do that publishing those commits is a separate action, via pushing to shared repository or asking others to pull from yours.Ĭhanging already published commits is awkward, of course, since it would cause others to lose history they already have Git will warn people pulling from you of that, and you might not even be allowed to push such changes to a shared repository. With Git, however, this is not a problem, since you are committing to your own private repository. This makes undoing a commit problematic how do you retract a commit others have already checked out or merged? With centralized version control, committing and publishing a change are the same thing: as soon as you commit to the shared repository, others can see and start using your changes. This chapter is about undoing or correcting changes once youâve committed them. In Chapter 3, we discussed staging changes in the index for inclusion in the next commit. ![]() ![]() Now, it is possible that you've heard of something called p a s, w at some point, and SPSS was briefly called predictive analytics software.ĭuring a trademark dispute after SPSS got bought by IBM, it only lasted for a year or so and it got resolved. Now for this course, I'm using version 22 on a Macintosh computer.įortunately, there haven't been any extraordinarily major changes between 22 and 24.Īnd everything I'm going to show you in this course will work just fine in almost any other version of SPSS. So the things we're going to talk about are versions, those are the release updates, the old version one version two additions, those vary according to what's included in a particular purchase.Īnd modules are extra functions that you can get to add on to the abilities of SPSS.Īnd at that point, it was called statistical package for the social sciences SPSS version 24 came out in 2016.Īnd now it's called IBM SPSS Statistics act like SPSS doesn't stand for anything. The choice is really making me think of an overwhelming a plethora of possibilities ahead of you.Īnd it's nice to break it down a little bit. To do that, however, we need to take a minute and talk about versions, additions and modules, which all refer to different kinds of things in SPSS. The first thing we need to talk about in SPSS and introduction is setting up and getting ready to do the work. Number one, SPSS, despite being developed about 40 years ago, is still popular.Īnd it's easy to save and reuse the syntax, giving you a code basis for the work that you do within SPSS. You can save that code as what's called a syntax file.Īnd then you can reuse it, you can adapt it and you can share it with others.Īlso, SPSS is really well adapted for data from experiments, where you're comparing means via t tests and analysis of variance, several important options like effect sizes and power analysis built in.Īnd so those are some of the reasons for SPSS is popularity, especially within academic research. It's kind of point and click interface, which allows you to assemble code really quickly. Now, there's some reasons that SPSS is popular in these fields. Really what this tells you something about the population or the audience for SPSS, the primary audience of SPSS is academic researchers, especially in the social sciences, but in other fields like business. ![]() In 2015, one major source of tech jobs, SBS is on the list, but this time, you see, it's actually a lot lower, it's number six.Īnd so there is a difference here, between academic publishing and employment in analytics. Here's another chart that is also from our for stats Comm.Īnd what this shows is analytics and job listings on. SPSS is number one, by far in terms of scholarly research. Here's a chart right here that comes from the excellent website are for .Īnd what it shows is the number of scholarly articles published in 2015, using various statistical packages and languages.Īnd we can see here is right at the top is SPSS Statistics. One important thing to know is how popular SPSS is. Once upon a time, it stood for a statistical package for the social sciences. Now, SPSS, the name deserves a little bit of explanation. This course from university professor Burton Paulson will show you how you can use SPSS to explore your data for actionable insights.Īnd in this course, we're going to look at these statistical program SPSS and some of its basic functionality, and give you an idea of what it can do and how well it might work in your own data work. You are about to learn about the popular statistical application SPSS from IBM. 2/23/2024 0 Comments Epic sports legitTheir mission is to give customers the best selection of sports gear, clothes, and fan merchandise at prices they can manage.

![]() 3M VHB is extremely affordable and can replace most kinds of fasteners. Traditional fasteners can be pricey and require lots of storage to keep track of all the different parts you need. Application is as simple as applying the tape and connecting the pieces together. There’s no need for drilling holes or welding objects together. But 3M VHB is more than just a double-sided tape: it’s an easier way of doing things. Traditional fasteners have probably been working just fine for you, and you might doubt that an adhesive tape can work as well. If you’ve never used 3M VHB tape before, you might be wondering why you should make the switch. Can bond to a textured surface, but the hold won’t be as strong.Ĭontrol Panel Overlays Why You Should Use 3M VHB Tape Irregular surface: No, must be applied to flat surfaces.Bond: HSE plastics, wood, glass, ceramic, stone, etc.Application temperature: Apply in temps as low as 50☏.Surface temperature: Continuous up to 194 ☏.Like VHB, Gorilla Tape is clear and won’t yellow over time. Gorilla Tape can hold up to 30 pounds and can be applied in temperatures as low as 50 ☏. Unlike 3M VHB, however, Gorilla Tape won’t bond well with low surface energy plastics such as polyethylene and polypropylene plastics. Gorilla tape can be used both indoors and outdoors on wood, glass, brick, ceramic, stone, and some plastics. Like VHB, Gorilla tape has adhesive on both sides so that it can be used to bond two different objects. When trying to find the best double-sided tape, you might wonder how Gorilla Tape stacks up against 3M VHB. Is Your 3M VHB Really 3M VHB? 3M VHB vs Gorilla Tape Shape: A converter can manufacture VHB in custom shapes to fit your needs.VHB can be applied to surfaces that are not flat.

VHB can be engineered to bond to just about any surface, including low-surface energy plastics. ![]() If you’re trying to bond two dissimilar substrates, VHB can be customized with a different adhesive on each side of the tape. From exposure to solvents to heat cycling, there’s a VHB style that will work for you. VHB double-sided tape can also be configured to withstand various extremes. This means the tape acts both like a viscous liquid, filling in gaps and holes, and like an elastic solid, flexible but strong.ģM VHB comes in clear, black, gray, or white tapes of differing widths and thicknesses. Made from a closed-cell acrylic foam, 3M VHB’s secret weapon is its viscoelasticity. VHB, which stands for Very High Bond, was one of the first of its kind and still outperforms other tapes on the market. Since it hit the market in the 1980s, 3M VHB has been one of the best-performing double-sided tapes. What is 3M VHB Tape?ģM VHB is a permanent, double-sided tape that can replace many traditional fasteners. But, if you need extreme strength and long-lasting hold, 3M VHB is your best bet. For bonds that need cushioning but don’t require extreme strength, consider one of 3M’s many double-sided foam tapes. These tapes are strong but thin, conforming to even irregular shapes. When you need a low profile, you might consider one of 3M’s thin-bonding tapes. If you’re wondering which of 3M’s double-sided tapes are the best, that answer is going to depend on what you need it for.ģM makes a variety of double-sided tapes that perform well under industrial conditions such as high temperatures. 3M’s double-sided tapes are no different.

The Pareto principle always applies usually a very small number of opportunities will deliver most of the company’s cash flows over the next decade. For CFOs to maximize value creation, they must rank the company’s 20 to 30 most value-accretive projects regardless of whether they are AI-related. Moreover, company capital (or access to more capital) is finite, and projects compete with one another. Gen AI holds the potential to be a revolutionary technology, but it doesn’t change foundational principles of finance and economics: a company must generate a return above its cost of capital. The most important action that CFOs should take is to identify the largest opportunities for value creation-and then make sure that they receive the money and other resources that they need. Gen AI and enterprise-level value creation In this article, we’ll discuss how CFOs can most effectively approach gen AI company-wide, prioritize specific use cases within the finance function, and rapidly climb the gen AI learning curve. CFOs should select a very small number of use cases that could have the most meaningful impact for the function. Similarly, in leading the finance function, the CFO can’t implement gen AI for everyone, everywhere, all at once. Instead, it’s the CFO’s role to allocate resources at the enterprise level-rapidly, boldly, and disproportionately-to the projects that create the most value, regardless of whether they are driven by gen AI. Instead, the ideal is that each will complement and enable the other, with new innovations in robotics and automation, to make human lives better, more creative, and more self-fulfilling.įor more about gen AI, see “ The state of AI in 2023: Generative AI’s breakout year,” “ The economic potential of generative AI: The next productivity frontier,” “ The organization of the future: Enabled by gen AI, driven by people,” and visit our featured insights page “ Insights on Artificial Intelligence,” all on .īut value doesn’t create itself.

It featured all of the same capabilities of the Express, but instead of maxing out at 10 users, it supported up to 50. The company unveiled the first Extreme in 2003, and as with the Express, it used an 802.11g chip. For power users, Apple also unleashed the Airport Extreme, which takes the Express's concepts and beefs them up significantly. The Express isn't the only AirPort in town. And if you're on a Mac, built-in Bonjour capabilities mean users on the network can easily find one another to share pictures, videos or any other kind of data. Plug it into a printer via the USB cable, and presto, any of those 10 users is able to print documents wirelessly. Security-wise, you can set the Express to use WPA (Wi-Fi Protected Access) or WPA2, 40-bit or 128-bit Wireless Security (WEP) and MAC address filtering.Ĭonnect AirPort to your DSL (direct subscriber line) or cable modem, or your Ethernet network, and it provides wireless Internet access for up to 10 users. It's also compatible with both Mac and Windows operating systems. Its small form factor means the Express slips neatly into the side pocket of even a svelte laptop carrying case. When you see the message of Setup Complete, click Done.and you are done.That's a lot of features for a device that's only 3.7 inches (9.4 centimeters) high by 2.9 inches (7.5 centimeters) wide and 1.1 inches (2.8 centimeters) thick. This confirms that the setup "wizard" has picked up the Ethernet connection between the TC and Express and will apply the correct settings to the Express. Watch the next screen carefully to see that the AirPort Express is being set up to extend using Ethernet. Type in a short simple name that you want to call the Airport Express It will take a few seconds to analyze things and then display a screen that looks like the example below except that you will see your devices and network name displayed When you click on AirPort Express, that will start up Apple's setup "wizard".

Luckily though.spicyorangemsp offers a $150 service to flash any ecu to MP3 settings.so if you want to completely remove the system, do it while having your ecu flashed.you can then completely remove all parts of the system, never get a code, and have a start up procedure that feels the exact same. The Mp3 ecu has a cold start protocol for starting WITHOUT the VTCS.the p5s and sedans do not.So when you remove or disable the system on regular proteges.you get a code (unless you just leave the actuator hanging there), but will definitely not have a proper warm up s not a huge deal, but your engine will run like shat until its warmed up properly.and its advisable to not even move the car for at least a minute or 2 after starting. ![]() The VTCS attacks this problem from the other restricts air flow, and by doing that, will automatically richen the mixture.No more fuel is used for a cold start than normal idling, and with very little air making it in there is little threat of it leaning out.resulting in too fast warm up, detonation, etc.the tumbling effect also does what was mentioned in earlier posts, by keeping the mixture swirling and not 'sticking' to cold surfaces.īut.the important part is a key difference with how the system is controlled.All proteges use an open loop cold start up map. The traditional way to fix this issue during warm up is simply to pour more fuel into the engine.making it very rich will slow warm up (good for the life of the engine), and guarantee enough aerosolized gasoline is in there to burn.as after the cylinder walls are coated with liquid gas, the rest will remain air born.But obviously, the government hates this. Fuel condenses on cylinder walls and piston heads, and doesn't burn properly. The posts above are great.the only thing i'd add is to think of the VTCS system as a simple 'choke' for cold starts.When an engine is not up to operating temp, it behaves very differently than when it is. VTCS is 100% not even for improving anything driver doesn't make the car run 'better' when s entirely emissions related, but the ecu in equipped cars is designed to use the system.VTCS drops the 'normal' BJ proteges into U-LEV compliance.where as the MP3 does not have this, and is only LEV compliant. On the passenger side of the intake manifold you can see a dual solenoid thing with two actuator arms coming from it, the arm heading just under and behind the fuel rail is for the VTCS (the butterflies are right at the very end of the intake runners.the electrical control and connections is mounted on top of the runners, but i forget which is VTCS and which is VICS. I found a pic of the butterflies if you're curious (see this thread for more): I'd like to know if they saw a noticeable increase in mileage (I suspect that won't be the case) and if they live in colder climates I'd like to know if they noticed that their car idled shittier after a cold start in the winter. Clearly it's not super important (they left it out on the MP3) and it doesn't stay on for very long except for very cold days (a cold but idling engine will have a coolant temp of >65C in less than 5 minutes on an average day). I'd also be interested to hear from people who've removed their VTCS. This results in better combustion on cold starts and less wasted fuel. The "tumble" helps keep the incoming air/fuel charge in the middle of the cylinder away from the walls. This should help increase fuel economy because on a cold engine when fuel hits the cylinder wall it condenses and doesn't end up getting burnt, some of it gets scraped in the crankcase and some gets pulled through with the exhaust gases. This makes the air/fuel mixture heading into the cylinders much more homogeneous and (because of the tumble) less likely to hit the cylinder walls. The smaller passage greatly increases the air's velocity which promotes swirl and the positioning of the hole promotes tumble. The butterflies close all the way, air can still get through because there's a smaller passage cut out on each butterfly. If either of those two conditions are not met they won't close. The butterflies are closed if two conditions are met: the coolant temperature is less than 65C and the engine RPM is less than 3000 (see page 01-03B-57 of the service manual). Under normal conditions the VTCS butterflies are open, that way the car will still run well if there's a problem with the VTCS solenoid or actuator. |
