There's the intelligence-gathering missions where you interview half a dozen people with boring stories and report back to whoever needs the information. Chronopolis: Chronopolis may look cool but is overstuffed with dumb, grindy tasks.Just chuck 'em on the map, let me fight them, and call it a day. Collecting character tokens: I'm not a huge fan of needing to re-visit levels or complete quests to unlock characters.The environments in which they are set are sometimes interesting, but the rest feels uninspired. Level design: the level design is really not very good.I hope we see this in the next original Lego game. Story progression: I liked the ability to choose what to do next.Flying around it is a lot of fun, and I give the developers extra points for actually putting something underwater. Environment design: Chronopolis may have its faults, but it at least looks cool with the combination of different environments and worlds.DLC Character roster: again, really good, and many of the DLC characters are far more interesting than those in the main story.New additions like the Inhumans and the Guardians of the Galaxy adds some extra spice to the story, although I will say that the line-up of Avengers seems to be lacking a few big names. Character roster: despite not getting the X-Men and the Fantastic Four this time around, the roster is great.My review is for the Nintendo Switch version with all DLC. Since that's now unlikely, here's my review, which summarises what I liked, what I didn't like, and what was plain out terrible.

The Creator of the universe loves us, each of us, personally! What a wonder! Hallelujah! Amen. But every now and then, we are blown away by the depth of your love. The most amazing thing about you, Lord, the most mysterious thing to us, is your love. Help us to trust you, even when your ways are frustratingly different from what we would expect and desire. Your ways are higher than ours, so much higher! As you know, Lord, sometimes this is distressing to us, especially when it seems like your love and justice are taking a nap. There is so much about you that we will never understand, at least not this side of Heaven. Yet we accept the limitations of our knowledge. How blessed we are to know you, to serve you, and to love you! Your revelation, in history, in Scripture, in Jesus Christ, and in our hearts, is a priceless gift. Gracious God, first of all, we want to thank you for making yourself known to us. When have you felt overwhelmed by the wonder of God’s grace? PRAYER: What about God do you find hardest to understand? How do you feel when you can’t figure out God? The more we reflect upon the mind-blowing goodness of God, the more we’ll echo the words of Paul in Romans 11:33: “Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgments, and his paths beyond tracing out!” For Paul, as for us, the mystery of God’s grace leads to astonished praise. I’m talking about the wonder of God’s grace, his limitless mercy, his unfathomable love. Yet, the greatest mystery of God’s nature leads us not to exasperation but to exaltation. For example, when God allows the innocent to suffer, when he fails to act in ways that would seem to bring him glory, and when he appears to say “no” to our fervent prayers, we struggle to accept God’s inscrutability. Sometimes they are frustratingly mysterious. Sometimes they are gloriously mysterious. Enhanced with AI to help you remember without wasting time on categorizing. The Lord made this clear in Isaiah 55:8, “For my thoughts are not your thoughts, neither are your ways my ways.” A private place to save your most precious notes, images, quotes and highlights. Over time, I have come to realize that, although there are many things we can know about God because he has revealed them to us, our understanding has limits. Nor did I account for how sin gets in the way of our knowing God. I didn’t take into consideration my own limitations as a human being and God’s unlimited nature. In retrospect, I think my desire to know God was laudable, but my expectations were naïve. I thought that if I worked hard enough and was completely logical, then everything about God would ultimately make sense. When I was a teenager, I wanted to figure out God. “As the heavens are higher than the earth,Īnd my thoughts than your thoughts.” Isaiah 55:8-9 The entrepreneurs also agreed to Greiner and Cuban's equity rising to 30% when Gatsby's sales hit $10 million, and further upping their equity to 40% at $50 million sales. The Bouton brothers walked off with a $250,000 investment in exchange for 20% equity and another $250,000 in loan. Kevin O'Leary proposed the $500,000 investment as venture debt, but it was ultimately a joint deal with Greiner and Mark Cuban that the entrepreneurs chose. Guest shark Candice Nelson also backed out due to concerns over their packaging and the overemphasis on calorie content. John confessed that he didn't see what value he could add to Gatsby, adding that it was he who would be calling the Halo Top co-founder for advice. Although the Sharks largely didn't see big issues with Gatsby's sales or its valuation, not everyone was keen on the low-calorie chocolate business. Calling them "creatures of a food-scientist's lab" that are "highly processed chocolate-like substances" at best, one Redditor pointed out that Gatsby's low-calorie chocolates come at the cost of highly processed components.ĭespite $2.5 million in sales from over 6,000 distributors the previous year, the Bouton brothers admitted that they had actually lost $3.5 million. Although more research is needed on this relatively new sugar substitute, not everyone has positive things to say about the ingredients that Gatsby Chocolate uses. The third ingredient that Gatsby Chocolate uses is allulose or D-psicose, a sugar substitute that has 70% of the sweetness of sugar but with fewer calories. MCT oils such as palm kernel oil, on the other hand, have 10% fewer calories than LCTs like olive oil, which is why it is a popular swap. EPG is a fat replacement ingredient derived from canola that Epogee - the company that Gatsby Chocolate sources its EPG from - claims can cut 92% of the calories that come from fat without compromising on flavor and texture, which may be why Gatsby's confections retain a decadent texture despite slashing the calories (via Epogee). Gaps can provide clues about the price movement. In layman’s terms, gap represents a price range at which (at the time it occurred) no shares changed hands. Gatsby uses allulose, EPG (esterified propoxylated glycerol), and MCT (medium-chain triglycerides) oil across its chocolates. Key Takeaways: A gap is produced when on a particular day a certain stock at its lowest price is traded higher, compared to its highest price at which it was traded on a preceding day.

We’ve outlined the major differences between the two in our comparison guide Adobe Premiere Pro vs Apple Final Cut Pro. Apple Final Cut Pro, meanwhile, is an excellent choice if you want to stay within the Apple ecosystem without compromising on pro features. Like Macs, it sets an industry-standard in the creative sector, packing a mighty range of Hollywood-grade tools for post-production work. So, when it comes to finding the best video editing software for Macs, a large part of it comes down to choosing which tool fits your workflow.Īdobe Premiere Pro is our pick for best video editor. Happily, modern Macs are well up to the task. Whether you’re running premium, top-end editing tools or the best free video editing software, these programs can be very resource-intensive, demanding real power to run them without lag, delay, or other performance-related issues. What is the best video editing software for Mac? If you'll be editing video on the go, then a MacBook will serve you well, but if you'll be working from a single location, then a powerful Mac desktop will be apt. Make sure to consider the design and portability of the Mac. For this reason, you see a lot of crossover between video editing Macs and the best laptops for graphic design and best laptops for photographers. With the right specs, you'll also have no trouble running the best graphic design software or visual effects apps, which are performance-driven programs. You'll need the best RAM and best GPU you can buy if you work with resource-intensive apps like best 3D modeling and rendering software, best VFX software, or engage in 4K editing, and 360° video editing. If you're frequently editing 4K material, you'll need a lot of storage to boot. You'll want to consider the storage depending on the kind of footage you work with. There are major benefits with the latter, which make a significant difference in performance (and your productivity) compared to running your software on Intel chips. One of the first decisions to make is whether to opt for an older model powered by Intel, or new Macs, which use the M-series chip - one of the best CPUs available. The perfect Mac for you will vary depending on the type of footage you edit, the resolution, output formats, and also if you'll be doing online or offline editing. When selecting the best video editing Mac for yourself, you'll want to start with assessing the kind of projects you work on or are planning to work on. Read the full Apple Mac Pro review Best video editing Mac: Frequently Asked Questions How to choose the best video editing Macs for you It also has a lot of holes on the side that allow plenty of air to flow inside the enclosure to cool the electronics down. The machine has a metal frame and is quite sturdy. Besides, with the iMac Pro no longer available, this truly is the most professional desktop Apple's selling. Still, if now is when you're in the market and you have the money to upgrade the specs substantially, you won't be upset with this current model. Since then, high-speed and efficient Apple silicon-based machines have arrived, showing the world where things are headed on all Macs - including a future Mac Pro that could come in 2023. Though powerful and heavily customizable, it's now been over two years since Apple released it. The third-generation Mac Pro is Apple's high-end computer and most potent and has the price tag to prove it. The default parameters will run fans at 100% speed at temperatures > 50☌, and run them a 20% speed if < 30☌, which corresponds to the usual recommended drive operating temperature. If you use both fancontrol and HDD fancontrol, be careful not to make them control the same fans. The fancontrol daemon is not needed for HDD fan control to operate. HDD fancontrol and fancontrol are unrelated. On Ubuntu and other Debian derivatives, it is part of the fancontrol package, that you can install with sudo apt-get install fancontrol. To query fan characteristics, you may also need pwmconfig. Install HDD Fan control: python3 setup.py install.If you don't already have it, install setuptools for Python 3.On recent Ubuntu and other Debian derivatives: sudo apt-get install hdparm smartmontools. Install hdparm and hddtemp or smartctl.Install HDD Fan control: pip3 install hddfancontrol.If you don't already have it, install pip for Python 3.Some Linux distributions have a hddfancontrol package available in their repository: Most motherboards and SATA drives fit these requirements. exposes to the OS a sensor to query fan speed.exposes to the OS a PWM to control fan speed.A least one SATA hard drive, that supports:.Can also optionally monitor CPU temperature, and control fan speed accordingly.Can be configured to never set the fans below a certain speed (useful if the fans controlled by HDD Fan control are the only ones available in the chassis).Can be set to stop fans or run them at full speed at customizable temperatures.Can adapt to different fan characteristics.Can automatically spin down drives after a customizable period of inactivity.
The converse effect was mathematically deduced from fundamental thermodynamic principles by Gabriel Lippmann in 1881. The Curies, however, did not predict the converse piezoelectric effect. Quartz and Rochelle salt exhibited the most piezoelectricity.Ī piezoelectric disk generates a voltage when deformed (change in shape is greatly exaggerated). They combined their knowledge of pyroelectricity with their understanding of the underlying crystal structures that gave rise to pyroelectricity to predict crystal behavior, and demonstrated the effect using crystals of tourmaline, quartz, topaz, cane sugar, and Rochelle salt (sodium potassium tartrate tetrahydrate). The first demonstration of the direct piezoelectric effect was in 1880 by the brothers Pierre Curie and Jacques Curie. View of piezo crystal in the top of a Curie compensator in the Museum of Scotland. Drawing on this knowledge, both René Just Haüy and Antoine César Becquerel posited a relationship between mechanical stress and electric charge however, experiments by both proved inconclusive. The pyroelectric effect, by which a material generates an electric potential in response to a temperature change, was studied by Carl Linnaeus and Franz Aepinus in the mid-18th century. The piezoelectric effect also finds everyday uses, such as generating sparks to ignite gas cooking and heating devices, torches, and cigarette lighters. It is used in the pickups of some electronically amplified guitars and as triggers in most modern electronic drums. It forms the basis for scanning probe microscopes that resolve images at the scale of atoms. The piezoelectric effect has been exploited in many useful applications, including the production and detection of sound, piezoelectric inkjet printing, generation of high voltage electricity, as a clock generator in electronic devices, in microbalances, to drive an ultrasonic nozzle, and in ultrafine focusing of optical assemblies. įrench physicists Jacques and Pierre Curie discovered piezoelectricity in 1880. The inverse piezoelectric effect is used in the production of ultrasound waves. Conversely, those same crystals will change about 0.1% of their static dimension when an external electric field is applied. For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0.1% of the original dimension. The piezoelectric effect is a reversible process: materials exhibiting the piezoelectric effect also exhibit the reverse piezoelectric effect, the internal generation of a mechanical strain resulting from an applied electric field. The piezoelectric effect results from the linear electromechanical interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry. It is derived from Ancient Greek πιέζω ( piézō) 'to squeeze or press', and ἤλεκτρον ( ḗlektron) ' amber' (an ancient source of electric current). The word piezoelectricity means electricity resulting from pressure and latent heat. Piezoelectricity ( / ˌ p iː z oʊ-, ˌ p iː t s oʊ-, p aɪ ˌ iː z oʊ-/, US: / p i ˌ eɪ z oʊ-, p i ˌ eɪ t s oʊ-/) is the electric charge that accumulates in certain solid materials-such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins-in response to applied mechanical stress. Electric charge generated in certain solids due to mechanical stress Piezoelectric balance presented by Pierre Curie to Lord Kelvin, Hunterian Museum, Glasgow There is a method to do this with the rlocfind command in MATLAB. The root locus near the zeros and percent overshoot line. Need the cancellation of poles and zeros near the imaginary axis, so we need to select a gain corresponding to a point on Overshoot and a fast response, we need to select a gain corresponding to a point on the root locus near the real axis andįar from the imaginary axis or the point that the root locus crosses the desired damping ratio line. Recall that we want the settling time and the overshoot to be as small as possible. Now that we have moved the root locus across the 5% damping ratio line, we can choose a gain that will satisfy the design Now let's change the axis to see the details of the root locus. In your m-file add the following lines of code: Poles at 30 and 60 and the zeros at 3+/-3.5i. It seems that a notch filter (2-lead controller) will probably do the job. We'll also need two poles placed far to the left to We will probably need two zeros near the two poles on the complex axis to draw the root locus, leading those poles to theĬompensator zeros instead of to the plant zeros on the imaginary axis. We will put another two poles further to the left on the real axis to get fast response. Two zeros very close to the two poles on the imaginary axis of uncompensated system for pole-and-zero cancellation. Make all of the poles and zeros move into the left-half plane as far as possible to avoid an unstable system. These poles and zerosĪre almost on the imaginary axis, they might make the bus system marginally stable, which might cause a problem. The command sgrid is used to overlay the desired percent overshoot line on the close-up root locus you can find more information from commandsįrom the plot above, we see that there are two pair of poles and zeros that are very close together. Note from the specification, we required the maximum overshoot,, to be less than 5% and damping ratio,, can be found from the approximate damping ratio equation. In your m-file, add the following command and then run the file, you should Let's first view the root locus for the plant. By adding zerosĪnd/or poles to the original system (adding a compensator), the root locus and thus the closed-loop response will be modified. The main idea of root locus design is to estimate the closed-loop response from the open-loop root locus plot. Therefore, the dominant poles are the roots -0.1098+/-5.2504i, which are close to the imaginary axis with a small damping We are now ready to design a controller using the root locus design method.įirst let's see what the open-loop poles of the system are: R = roots(denp) The system model can be represented in MATLAB by creating a new m-file and entering the following commands (refer to the main problem for the details of getting those commands).ĭenp= ĭen1= Step, the bus body will oscillate within a range of +/- 5 mm and will stop oscillating within 5 seconds. For example, when the bus runs onto a 10-cm (X1-X2) has a settling time less than 5 seconds and an overshoot less than 5%. We want to design a feedback controller so that when the road disturbance (W) is simulated by a unit step input, the output From the main problem, the dynamic equations in transfer function form are the following:Īnd the system schematic is the following where F(s)G1(s) = G2(s).įor the original problem and the derivation of the above equations and schematic, please refer to the Suspension: System Modeling page. |
