![]() Overall, I think it's safe to say Microsoft has reached a stable platform for Surface Duo with the core features and functions behaving as they should. I also echo your request for SwiftKey, which is still not as good as Gboard for typing, and it has had handwriting recognition support for years. Same with more Surface Pen support, making Surface Duo stand out from nearly all other Android phones besides whatever Samsung releases. It means Google will presumably update all its inbox apps like Gmail, Gboard, YouTube, Maps, Messages, the Play Store, etc., to support its own recommended APIs. I'm more excited about the developer options than the OS itself. That's fine, as not all apps need to support it, but I suspect with Android 12L coming to Duo later this year, we'll start to see some app developers target those APIs and build apps that, at the very least, avoid the gap down the middle of the two halves.ĭaniel Rubino (Image credit: Daniel Rubino)ĭaniel Rubino: Yeah, I agree with Android 12L and apps being updated. So far, only Microsoft's apps (and a handful of third-party apps) support this mode. I think what I'm most hoping for is broader adoption of third-party apps taking advantage of the spanning capability on Duo. It would also be nice if SwiftKey would adopt inking to write into text fields. Additionally, I'd also love to see Microsoft put more emphasis on pen integration things like adding the ability to take notes and ink directly on the lockscreen instead of unlocking and opening OneNote first. I communicate through Telegram, Skype, and Slack, not SMS or phone calls. It's such a cool idea, but I never get to use it because I don't often get to use the few apps it supports. Zac Bowden: Improvement to the Glance Bar is my most significant request. Will they find it helps their productivity flow? I certainly think it helps mine, but not everyone is the same. But now, the software works as intended, this is the first time we're able to see how ordinary people take to the dual-screen nature of this device. Beforehand, I think many people couldn't get used to the dual-screen aspect because the software was rough and wasn't making it easy. ![]() Now that the software works as intended, we can finally see if people prefer dual-screens over single-screen multitasking. I think that says a lot about how much better Microsoft has handled the production and rollout of Duo 2. The Duo 1, at this point, was almost 50% off, but the Duo 2 is nowhere near that. But I don't think that's fair on the Surface Duo 2, which is just starting to see a small price cut. Many people will see the price being cut here and there and think it's because the device is failing, so retailers are dumping stock because this exact thing happened with the Surface Duo 1. Even though both are no longer in that state, it will have this stigma of being a buggy mess like the first Duo. Unfortunately, those initial rounds of Duo 2 reviews sealed this device's fate.

Stonedahl, Forrest, William Rand, and Uri Wilensky (2010), "Evolving Viral Marketing Strategies," Genetic and Evolutionary Computation Conference (GECCO), July 7-11, Portland, OR, USA Ideally it would be possible to set a number of infected turtles, and choose proportions of centrality measures to infect these turtles. These could be extended as well.įinally, the model only allows users to choose one centrality measure by which to initially infect turtles. ![]() If the model were to fully implement the NPV of a model, the value of each infected node would depend on at what time it was infected.įurther, the model currently allows for only two different network types and four centrality measures. Currently the model simply measures how fast a virus spreads on a network, but does not take into account how fast it is spread to each individual node which is one way to calculate the net present value (NPV) of a strategy. The model was inspired by the Local Viral Marketing Problem (Stonedahl, Rand & Wilensky 2010) of an adoption network. Are there particular measures that might result in a faster spread in particular types of networks, but not in others? Why do you think that is? EXTENDING THE MODEL Try to set up different kinds of networks, and select the initially seeded turtles by different centrality measures. When you click SETUP, the network will be generated, and when you click GO, nodes will start infecting their neighbors. Then choose how many turtles are initially seeded and by what centrality measure these turtles are selected. The model stops when the whole market is saturated. At each tick, each turtle has a small chance of adopting the product on their own (1%), and a larger chance of adopting the product if any of their friends have adopted the product (0.5 * the ratio of neighbors who have adopted to the number of all neighbors). A number of turtles are seeded with the product at time 0. When the model is set up, 500 turtles are created and connected in a network of the type selected (preferential attachment or a random network). Its purpose is to allow you to explore the relationship between different centrality measures, and different network types, and see if the interactions between them make for faster or slower spread of the product. This model is a simple experiment that allows researchers to examine how to best seed a network to maximize the adoption rate of a product by using viral marketing. The model, as well as any updates to the model, can also be found on the textbook website. This model is in the IABM Textbook folder of the NetLogo Models Library.

They also claimed that noise can contribute to indirectly increasing the rate of accidents by causing stress, attention loss, and blood pressure increases, etc. noted that noise is one factor that can increase the risk of accidents in the workplace by interfering with communication. Although some studies showed the positive effects of noise on cognitive performance, multiple studies have demonstrated the negative effects of noise. Noise has been emerging as one of the main causes of negative cognitive task performance in industrial sites. Indeed, a number of studies have emphasized that an increase in a worker’s cognitive workload or a decrease in their cognitive task performance can lead to human errors and serious industrial accidents. Hence, it is known that human error remains the most common contributing factor in fatal accidents worldwide, and the ineffective mental workload of operators plays a role in such accidents. , the industrial accident rate due to human error was found to be high in Korea as well out of 351 cases of serious accidents that occurred in Korea in 2013, 117 (33.7%) were related to human error. In a similar vein, Hals found that human error was a primary causal factor in 70–80% of accidents in the oil and gas industry. Dinges also stated that unintentional human errors in the workplace, which can include mistakes by operators, maintenance, and management, were the most frequently identified root causes of accidents, contributing significantly to between 30% and 90% of all serious incidents across industries. argued that human error was one of the major reasons for industrial accidents, emphasizing the need to introduce new technologies to prevent it. Analyses of major accidents have concluded that human errors on the part of operators, designers, or managers have played a major role in their occurrence. These findings may be useful for the work-space designs that prevent/minimize human errors and industrial accidents by improving the cognitive task performance of workers in field-noise environments.ĭuring the past few decades, technological evolution has drastically changed the nature of the human factor problems that one faces in relation to industrial safety. The major findings were that: (1) the field-noise environment did not affect the scores of the Corsi block-tapping and 3-back tasks, significantly affecting only the Digit span task score (decreased by 15.2%, p < 0.01) and (2) the Digit span task performance in the field-noise environment was improved by 17.9% ( p < 0.05) when mixed noise was provided as a type of auditory pre-stimulation. The three STM/WM tasks were the Corsi block-tapping, Digit span, and 3-back tasks, corresponding to the visuospatial sketchpad, the phonological loop, and the central executive of WM, respectively. In the second experiment, the participants performed each of the three basic STM/WM tasks in a field-noise environment after they were provided with one of four different auditory pre-stimulations (quiet noise, white noise, field noise, and mixed (white and field) noise). In the first experiment, a total of 24 participants performed each of three basic short-term/working memory (STM/WM) tasks under two different experimental conditions (quiet-noise environment and field-noise environment) depending on the presence or absence of field noise. To accomplish these research objectives, two major experiments were conducted. Therefore, this study aimed to empirically investigate: (1) the effects of noisy environments on the performances of cognitive tasks related to different functions of working memory and (2) the effects of auditory pre-stimulation on the performances of cognitive tasks in a field-noise environment. Accordingly, studies on the effects of pre-stimulation in a noisy environment are still lacking. However, most previous studies demonstrated the effectiveness of the auditory pre-stimulation in a quiet environment. In recent years, auditory pre-stimulation has been considered as a means of preventing human errors by improving workers’ cognitive task performance. The accident rate due to human errors in industrial fields has been consistently high over the past few decades, and noise has been emerging as one of the main causes of human errors. ![]() Instead, the Green Knight picks up his head and places it on his body. With one blow, Gawain beheads the Green Knight. When King Arthur grants him this honor, the Green Knight hands Gawain the axe and bares his neck. Of King Arthur's knights, the youngest (who also happens to be Arthur's nephew), Sir Gawain steps forward to accept this challenge. He offers up the axe to anyone who can take it and strike him with it, on one condition: In one year and a day, the Green Knight will come back to court and return the blow. He does not want to fight anyone in the court, as he would surely win, but would like to challenge the knights in a holiday game. He comes before King Arthur and declares his intention. The Green Knight, large and imposing, rides into Camelot on a green horse, carrying no weapon but an axe and, in his other hand, a holly branch. The poem begins in Camelot on New Year's Eve, when, in the midst of holiday merrymaking, King Arthur asks to hear a story. What is "Sir Gawain and the Green Knight" about? Warning: The following article contains spoilers for "Sir Gawain and the Green Knight" and its 2021 film adaptation, The Green Knight. (For medieval poetry enthusiasts: Jones also narrates an Audible exclusive version of a pivotal part of The Canterbury Tales: its prologue.) Today, listeners alike who are interested in the poem, which would have been written around the same time as Geoffrey Chaucer's The Canterbury Tales, can find Tolkien's translation on Audible, narrated with wonder and whimsy by Monty Python’s Terry Jones. Tolkien, author of the Lord of the Rings trilogy, who was a noted academic and professor of English as well as the creator of fantasy epics. Perhaps the most famous translation is by J.R.R. It wasn't published until the 1830s since then, multiple translations, both academic and entertaining, have appeared. The poem dates back to the 14th century and, experts believe, survived as a manuscript that came into the possession of Robert Bruce Cotton, a Medieval English scholar and collector. The author of the poem is unknown, although the narrative draws from English, Welsh, Irish, and French stories from the same time period. It was written as a chivalric romantic poem, with alliterative stanzas, in Middle English. ![]() " Sir Gawain and the Green Knight" is an Arthurian tale about Sir Gawain, one of the knights of the round table, and his misadventures following a clash with the titular Green Knight. For centuries, tales of King Arthur and his knights have fascinated audiences as these legends have been told and told again, with fresh interpretations and new twists. Head to the final track to listen to Vienna Philharmonic harpist Anneleen Lenaerts’ full commentary on this concert. They unlock the full force of the work’s finale, in which Tchaikovsky delivers a life-enhancing blast of what he described as “festive merriment” before reminding listeners of fate’s habit of turning joy into sorrow. To play pizzicato on the guitar, first place the outside of the hand on the bridge of the guitar (as in a karate chop). ![]() Conductor and orchestra dig deep beneath the music’s surface to reveal a musical universe filled with complex emotions and inner tensions. Early critics associated the work’s first movement with the relentless march of fate, a comparison magnified by Tugan Sokhiev and the Vienna Philharmonic in their impassioned performance. Tchaikovsky’s Fourth Symphony catches fire from the moment of its mighty opening fanfares for horns and brass. “You have these big, lush romantic phrases and also popular themes and rhythms that make it very enjoyable to play and to listen to.” “She worked closely with him, so it’s very well written for the harp.” The piece, she observes, goes straight to the heart. Pizzicato-Polka (Strauss Jr., Johann) Movements/Sections Movts/Secs: 1 movement Composition Year 1869 Genre Categories. “Gliere was friends with Ksenia Erdely, who was a very important harpist at the time,” notes Anneleen. The three-movement concerto, written shortly before the Second World War, includes a set of variations on a haunting introspective theme and the exquisite dialogue for harp and orchestra that launches its finale. In this concert, exclusive to Apple Music Classical, Vienna Philharmonic harpist Anneleen Lenaerts brings the experience of recording the work to her entrancing performance at the Musikverein. We should be able to do this in rhythm and without much “foot shuffling”.Defined by its ravishingly beautiful music for soloist and the romantic lyricism of its orchestral themes, Reinhold Glière’s Concerto for Harp blends virtuoso display with passages of profound stillness and concentration. The goal is to be able to jump into perfect pizzicato position, and return to an optimal basic position. We can use any simple exercise or excerpt for this. To gain facility with the pizzicato technique, we can practice moving into and out of position. Practice Moving Into and Out of Pizzicato Position If we mute too little, the note will ring out as normal.īetween these two is a “sweet spot” where the note is still audible, but is shortened and altered in tone quality. If we mute the string too much, the note will come out as a “thud” or a “thunk”, and we won’t be able to hear the actual note. Through trial and error, we can find the perfect balance of pitch and duration. Listen for the Balance of Pitch and Duration This may be because of the lesser sound quality and projection of the higher-pitched pizzicato notes, or for ease of playing. ![]() While there are exceptions, the vast majority of pizzicato effects written in guitar music use the bass only. Most often, we only play pizzicato on guitar using the bass notes and strings. Usually Bass Guitar Strings Only on the Pizzicato When we play from this position, the flesh of the outer hand is muting the strings back by the bridge, though not completely. Next, roll the hand down toward the strings until the thumb comes within striking distance of the strings. To play pizzicato on the guitar, first place the outside of the hand on the bridge of the guitar (as in a “karate chop”). How to Play Pizzicato on Classical Guitar – Right Hand Position When we see music that calls for pizzicato playing, it’s usually abbreviated “pizz.”. ![]() Instruments using a bow (violin, cello, etc.) may use the end of their bow to pluck the strings for this effect. The result is a short, slightly muted sound, much like a jazz “walking bass”. “Pizzicato” translates roughly as “plucked”, or “pinched”. And one such special techniques on guitar is the “pizzicato”. Using special techniques, we can create varied sounds and textures. This is one reason Ludwig van Beethoven called the guitar “a miniature orchestra in itself.” ![]() Soundiiz’s Platform to Platform tool allows the transfer of various and multiple musical content ![]() In barely 1 minute you can transfer hundreds of elements from one platform to another. ![]() Your elements are then transferred to the destination platform.

From here, you can choose to save as a number of different types of files or upload directly to social media. Once you're completely satisfied with the edits on your photo, you can save the image by tapping the "Save & Share" symbol in the top right (arrow inside a sheet on iOS three interconnected dots on Android). If you need to delete a custom filter, all you need to do is long-press on the look you would like to delete, then tap "Yes." If you want to edit an already created filter in your "My Looks" category, the best way to go about it is to tap your filter, make your desired adjustments, save it as a new one, and delete the old one. You can also us the slider to adjust the intensity of your custom filters as well. Your custom filter will now show up in the "My Looks" folder (Android will create one when you save your first custom filter), so you can choose your custom filters just like you can Adobe's pre-made ones. Each folder has looks that are different yet similar, with enough variance to want to try them all out, so there's a lot to explore and play around with. There are many different filter options, which Adobe calls "Looks," and PS Express has organized them into folders labeled Basic (or Free), Charm, White Balance, Matte, HDR, B&W (or Black & White), Portrait, Nature, Pop Color (or Splash), and Duo Tone. Next, tap on the three circles to open your filters, if they aren't already opened (it usually opens by default). On your iPhone or Android phone, open the PS Express app, then select the photo you would like to edit. Photoshop Express allows for more customization, just like in Adobe Lightroom, but Photoshop Express is much easier to understand than the extensive and often-confusing options that Lightroom offers. On Instagram, you have filter options but are very limited to what it has chosen to include on its platform. With the Instagram craze booming, this fast, easy, and precise method of editing photos is a must. Then, you can even save those edits as your own custom filters. The options in Photoshop Express allow you to edit and change your filters to be exactly to your liking. It's simple, fast, and more customizable than using Instagram's pre-made filters. Just don't expect anything more than the most basic of imaging tools.Just like Instagram, Photoshop Express for Android and iOS has its own set of filters you can quickly apply to any photo.

Once you're done editing you can save your image to your device or to Adobe Revel, or share it via social media or messaging. There's an auto-adjustment tool too, if you can't be bothered to tinker around with the image yourself. Other tools within Photoshop Express include red-eye removal, borders and frames, and a blemish remover. Many of the adjustment effects and filters are free, though some you'll have to pay for. Alternatively, hit the Looks button and you can apply one of a number of preset filters to the image, in much the same way as you would with Instagram or Retrica, for example. You can use Adobe Photoshop Express to correct various aspects of a photo, including clarity, contrast, shadows, temperature, and more. There's an option to crop and straighten images, which includes the ability to flip the picture or constrain the proportions as you resize the canvas.

To make sure that my data is a bit more accurate and not just localized to a single NAS system, I also ran a similar test on an 8-bay Synology DS1817+ NAS with 10 Gbit connectivity that I reviewed last year. ![]() Nothing was changed on the iMac Pro from the configuration standpoint, with default /etc/nfs.conf, /etc/nf and /etc/nf files (if you are running an older version of macOS, you should edit the /etc/nf file and make sure to add “signing_required=no” to the file or your transfer speeds with the SMB protocol will suffer greatly). File System Analyzer within QNAP Diagnostic Tool showed that the volume’s potential was roughly 680 MB/sec read speed and 570 MB/sec write speed, which is pretty decent for four drives in RAID 0 configuration (with each drive potentially being able to do up to 180-190 MB/sec, according to HDD Analyzer). ![]() ![]() In order to make sure that the 4-bay QNAP device performs at its maximum potential, I used fast 7200 RPM 4x WD Red drives configured in RAID 0 configuration. The 4-bay QNAP device offers both Thunderbolt over Ethernet and 10 GbE connectivity options, so I tested both, although it turned out that Thunderbolt offered better overall performance, which is why I decided to stick with it instead of 10 GbE. I am currently in the process of reviewing another QNAP device, and while at it, I decided to test out all these protocols on the latest version of macOS Mojave 10.14.3 on my iMac Pro that has a built-in 10 GbE connection. Add to this the fact that macOS itself might behave differently depending on which version of it you are running, and it can get quickly aggravating for many photographers out there who are simply trying to get the best out of their equipment. With macOS allowing one to choose between AFP, NFS, SMB and CIFS protocols, it is sometimes tough to make the proper choice, especially considering that some of these protocols have different versions that might perform differently. LaserWriter 16/600 PS:LaserWriter 1.If you are a Mac user, you might be wondering which file-sharing protocol gives the best performance when using a network-attached storage device (NAS) such as Synology, or a NAS / Thunderbolt over Ethernet device such as QNAP.
