![]() ![]() ![]() Nanggala’s equally elderly sister-ship, Cakra, which has been subject to a recent modernisation and refit, may be taken out of commission to minimise the chance of another accident. There were new commissionings in 2017, 2018 and as recently as last month - with the first submarine to be assembled in Indonesia, the KRI Aluguro, accepted into service. The navy’s submarine arm has been challenged by its recent expansion from a force of two to five boats. However likely it is Nanggala experienced a material failure, there will still be a review of training standards and operational procedures. The Indonesian Navy will now be subjecting its own organisation to examination. Submarines are designed to hide – so what happens when one goes missing? Coupled with the selective recovery of components, this could help provide some answers. The best approach would be to follow up the initial video examination of the wreckage with a more detailed mapping of the wreck site and all the material strewn on the seabed. Submarines are large and complex machines and the “black box” systems in aviation would not cover all the possible problems that might have arisen with Nanggala. One could argue the resource-constrained Indonesian Navy has better things to spend its money on, including its remaining four submarines.įurthermore, there is no guarantee the specific cause of the disaster will ever be discovered. Only a handful of salvage organisations would even be capable of such a task. Nevertheless, bringing some 1,300 tonnes of metal back to the surface from a depth of more than 800m remains a formidable proposition. The United States’ 1974 mission codenamed Project “Azorian” involved the covert recovery (from much deeper water) of large components of a sunken Soviet missile-carrying submarine. This is possible and there is some precedent for this. Indonesian authorities hope to salvage Nanggala’s wreckage, according to reports. Indonesian Navy/AP How much recovery is worth the effort? The German-made submarine was reported missing on April 21. Photo released by the Indonesian Navy shows parts of submarine KRI Nanggala on the ocean floor. At 800m, Nanggala had no chance of surviving intact. But the risk of hull collapse increases very rapidly as depth increases. What is known as the “crush depth” will be much more than that. Submarines such as Nanggala have an individual safe operating depth of at least 260m. There is no hard and fast figure for the exact depth at which this occurs. Regardless of the trigger, the tragic fate of KRI Nanggala would have been sealed once it passed the depth at which its hull and fittings could not withstand the increasing pressure. Material failure is the more likely cause. ![]() Submariners, however, have very carefully developed and extensively drilled standard operating procedures. There could have been a fire, something particularly feared by submariners in their enclosed environment. It does not take much loss of buoyancy for a submarine to lose control of its depth. Causes could include a material or mechanical failure leading to catastrophic flooding of one or more compartments. So whatever went wrong likely did so as the submarine was diving.Īt this stage, it is impossible to know what triggered the incident. Nanggala’s discovery so early in the search suggests the boat was near its last reported position. It took one year to find Argentinian submarine San Juan after it sank in 2017. An image of the wreckage made available by the Indonesian Navy. ![]()

![]() ![]() ![]() This is what allowed Ori to fly in the first game, after all. Ori offers the owl Kuro’s feather to help, fastening it to their wing. But, the hatchling, with one small wing, is struggling to learn to fly. ![]() Life is good in the quiet forest, in other words. Ori is now living with his makeshift family as Will of the Wisps begins, raising an owl hatchling that had been left behind by Kuro, a hulking bird that antagonized Ori for much of the last game. Ori and the Will of the Wisps guide: Inkwater Marsh map and item locations The purified water below turned a deep, inviting, clear blue. The lake below was a marshy swamp, but, by executing a series of precise jumps through the clockwork structure and clearing away obstacles, I was able to get the wheel turning again. I was later dazzled as sunbeams lit up mossy gears that had once powered a massive waterwheel. I found myself dawdling in the dimly beautiful Inkwater Marsh during my first hour with the game, watching the flashes of lightning play on the plump leaves crowding the forest floor. Screenshots and trailers don’t do it justice. Will of the Wisps is even more sumptuous and varied in its aesthetic, filled with delightful details that make so many frames look more like paintings than a video game. Here was a striking 2D platformer that staked out the visual middle ground between a Pixar short and an oversaturated photograph of a fantastical forest. Moon Studios’ first game, Ori and the Blind Forest, was notable for the same reason. There is combat, sure, and there are threats, but the dance, and the beauty of your surroundings, are always the focus. I’m not 100% sure if these were intentional (in which case it’s bad design) or actual bugs.ĮDIT: I’ve also just now had the “Sticky” ability stop working for me, requiring me to restart the game to get it back.Ori and the Will of the Wisps invites you to dance inside a beautiful world. Moments before I was hopping along and zooming through a level and then at some points, I felt like I couldn’t get above a certain height while I was sure I should be able to. More annoying were the moments where the double/triple jump didn’t seem to give me any lift at all. Just goes to show that I don’t experiment enough with the different abilities & weapons in games, and it’s admittedly sad that a bug is required to make me see the error of my ways. Silver lining: it made me switch to the heavier melee attack and that turned out to be a much more effective way of dealing with enemies. Sadly there were a few bugs: On one occasion, Ori’s default attack stopped dealing damage at all. It would be a shame if people miss out on the complete experience because of it. I hope this is the Gamepass effect with people trying it out but not seeing it through just yet, and not an indicator of the game being too hard. The boss battles were challenging, but manageable even in higher difficulties, yet the fact that beating them unlocks a rare achievement worries me. This issue resolves itself through upgrading Ori along the way though, so perhaps this is simply the desired effect? Especially when you’ve already got their pattern down but are simply going through the motions, it becomes noticeable. Now, it’s okay to have challenging combat, but the enemies do feel a bit bullet-spongey at the start, taking just a bit too many hits to actually defeat them. While you start the game feeling threatened by even the weakest enemies, at the end of your adventure, you’ll be plowing through them like a furry Goku. Ori’s offensive arsenal has also received an upgrade: You can equip multiple melee or ranged attacks and upgrade them. ![]() ![]() ![]() Though weather stations are more about recording your local data than about getting forecasts, setting up and maintaining a weather station is a fun science project-just maybe not right before a hurricane hits. If you're really concerned about accuracy, consider getting a weather station of your own. Besides, right now you should be staying inside anyway to help curb the ongoing pandemic, even on the nicest of days. Despite earlier conspiracies, the rollout of the 5G wireless network shouldn’t ruin these weather forecasts. As it stands, we'll assume that if a company has invested the time and effort to create its own predictive models for something as complex as weather, then it probably knows more about meteorology than we do.įor what it's worth, the apps were all quite accurate during testing. We're simply not set up to tackle that kind of challenge. Second, and more importantly, to really determine the accuracy of the service's model, we'd have to perform exhaustive tests across the globe. The Weather Channel and a few other companies have their own predictive models, but many apps are just shells into which data flows. Some also pull their predictions from AccuWeather, or the National Oceanic and Atmospheric Administration. Our reasons are twofold: First, most weather apps get the bulk of their data from the National Weather Service. What we didn't look for is whether or not the predicted weather came to pass. If you have to dig through several screens to find out when it's going to rain, the app is off to a bad start. An ideal weather app is visually pleasing and easy to use. When testing weather apps, we spent most of our time evaluating the effectiveness of their design. A weather app lets you do that wherever you are, whenever you like. With wild weather across the country, particularly hurricanes threatening coastal states, it's a good idea to check the forecast or radar for upcoming conditions. A good weather app helps you decide if you'll need to bring an umbrella to work, or prepare for more serious conditions. ![]() One of the most important tools for that is a mobile weather app. ![]() Our weather network delivers the fastest alerts. When Mother Nature is in a bad mood (which is more likely than ever these days thanks to climate change), it helps to keep an eye on what's happening in the sky. WeatherBug is easy to use and provides forecasts for your every need, from storm warnings to pollen levels.

There is an increasing interest in developing visualization tools that enable users to perform operations by directly manipulating graphical encodings rather than external widgets such as checkboxes and sliders. We investigate direct manipulation of graphical encodings as a method for interacting with visualizations. This article is summarized in: Computer Science Teachers AssociationĬSTA's mission is to empower, engage and advocate for K-12 CS teachers worldwide. We also consider the role of frameworks in HCI as well as the future of the RBI framework. The article contributes a comprehensive methodology for evaluating the impact of frameworks through our twofold approach: content-based citation analysis, including the design of a new citation typology and a survey on the use of frameworks in education using a taxonomy of learning goals. We provide our findings about the impact of the framework both on contemporary research, through content-based citation analysis, and in HCI education, through a survey we conducted on emerging interaction frameworks. As a case study for investigating the impact of theoretical work in HCI, we present our evaluation of the impact of the Reality Based Interaction (RBI) framework, introduced by the authors in 2008. However, studying the impact of such theoretical contributions requires consideration of various perspectives and level of impact. Evaluating the impact of frameworks can identify whether and how a framework was used, how it has evolved, and what trends have developed over time. This review appraises the recent literature regarding the health benefits of anthocyanins and their molecular mechanisms in various oxidative stress related pathophysiological conditions.įrameworks such as Direct Manipulation or Instrumental Interaction have been an important force in HCI research. However, considerable variations in activities do exist among structurally diverse anthocyanins. ![]() Moreover, anthocyanins improve diabetes, obesity and cancer pathology by inhibiting NF-кB-mediated inflammatory pathways. Inhibition of the anti-inflammatory pathways also influences the modulation of arteriolar disorders and cardiovascular complications due to anthocyanin administration. Recent investigations have revealed that anti-inflammatory activities of anthocyanins follow the inhibitory pathways of NF-кB-mediated decline of inflammatory cytokines production. Major benefits of anthocyanin administration are owing to their potent anti-inflammatory and antioxidant activities. Many in vivo and in vitro studies reveal that anthocyanins have different health beneficial effects such as antioxidant, antidiabetic, anti-inflammatory, anti-obesity, antihypertensive and anticancer properties. The red, blue and purple colours of leaves, flowers and fruits of plants confirm that they are rich sources of anthocyanins. Anthocyanins are naturally occurring water-soluble plant pigments belonging to the flavonoids chemical class. ![]() ![]() ![]() Is the direction of the wind as important as the wind speed? And does the direction of the wind have an impact on the temperature in the United Kingdom? So that's why, is the principle now clear to you? It's no coincidence that you feel cold when the wind starts to blow.īy now you know that wind chill has nothing to do with a wind turbine, but is the name given to the effect of the wind on the felt temperature. Without this layer, our skin is then directly in contact with colder and drier air.* The consequences? The skin gradually dries out as it warms the air to restore this balance… which immediately cools our body (this requires a lot of energy). But this small insulating protection is perpetually blown away when it's windy! The principle is physical and rather simple, but not obvious: when there is no wind, a thin layer of warm air moistened by the body forms on the surface of the skin. It is simply the sensation of cold that the wind causes on a living organism that radiates heat (like your body), while there is no change in the actual air temperature. The wind chill is the correct term, better known in popular parlance as the felt temperature. More importantly, does wind chill have anything to do with wind turbines? Apart from the association with wind, not really… Does wind speed affect the felt temperature? The higher the wind speed, the greater the cooling. The feeling of cold is therefore reinforced when the wind joins the party, even with the same temperature. ![]() With a strong northerly wind, the felt temperature changes dramatically! The weather is important, especially in the United Kingdom where the climate is varied (but less so than in the northernmost regions of the world). On the one hand, the physiological perception of temperature varies from person to person, but on the other hand, it varies according to atmospheric conditions.Īs you know, a dry, calm, and sunny 20 degrees does not feel at all the same as 20 degrees with strong wind and rain. When we talk about air temperature or temperature under shelter, we are talking about the temperature measured with a thermometer or a probe placed 1.5 metres above the ground, inside an open-air shelter, well protected from the wind and the weather.īut the reality is often different, precisely because of the winds and the weather. Before discussing the influence of wind speed on the felt temperature it would be useful to have a better understanding of what we are talking about, right? So let's start with an update on the weather. ![]() ![]() ![]() If you’re a student, there are many more options for you than we have listed here below. Let’s take a look at some of the most important factors that should be considered when making the right CAD software decision: So if you’re lucky enough to know your way around this, you should be fine off with a free 2D CAD system.īut if you’re looking for a modern, faster way, you probably are better off with a 3D CAD solution. The saying might go like th is: if it ain’t broken, don’t fix it, right?Īnother reason for this is that most metalworking schools still teach students how to design flat patterns themselves, calculate bend shortenings based on material thickness, and k-factors. So, there is a high chance you’ll be fine with just drafting some 2D designs quickly. Many legacy manufacturers still work in 2D DWG and DXF drawings. What are the most important factors in the selection of a CAD software?įirst, you could draft in an old-school way and do it all in 2D. Sometimes you just want something simple, and ideally free.įor example, if you are designing simple folded sheet metal parts, you are only needing to design some flanges with rounded radii: a simple sheet metal module. But I know that not everyone is looking for the Rolls-Royce of sheet metal design solutions. It is hard to find the best free CAD software for metalworking in 2022.Īs a consultant, I have been on the lookout for the best CAD software that will fit the needs of my larger clients. ![]() What are requirements for Sheet Metal Design? CAD-files are typically also used to send directly to CAM-systems to create NC-codes, for example for sheet metal laser cutting or sheet metal die bending. Today, manufacturers use modern PLM and PDM systems and store their designs on the network or in the cloud. The use of CAD software has grown exponentially in the past two decades because it covers many aspects of design, including architectural design, mechanical engineering, product design, and more. As well, it helps engineers make their designs more accurate and easier to modify for later improvements. It helps users create designs in either 2D or 3D so that they can visualize the construction.ĬAD has replaced manual drafting often, resulting in significant productivity improvement by eliminating many manual actions and streamlining the design process. It permits to draw 2D/3D models that can be used for engineering documentation, as well as the models that are used for CNC Manufacturing. This article will show you five free CAD software programs that are easy to use, outstanding at their jobs, and suitable for 2D or 3D sheet metal design.Ĭomputer-Aided Design (CAD) software is an interactive digital design tool used to make models for engineering. That being said, let’s dive into how you can get started today. If you intend to use your CAD software just for some basic part design or learning the skills, you’re in luck – you can do this for free! There are few strong options out there such as FreeCAD, Onshape and Fusion360īut if you’re looking to design sheet metal for professional applications, chances are you’ll face some limitations in the free editions. ( looking at you, Blender!).įinding a CAD solution specifically for sheet metal products design is a bit tricky because you’ll either need a simple 2D CAD system, or ideally: a parametric or direct 3D modeler that allows you to design flanges and work with bend deductions: In short, a CAD-system with a dedicated sheet metal module. If so, you’ll know that’s difficult because there are many software tools that might look like the coolest and simplest solution, but after you finalize your design, you realize it’s just not really suited for the goal. Have you ever searched for a free CAD software to design parts, in particular for sheet metal? ![]() ![]() ![]() The issue of this project is that it seems to forget the essential dimensions to be PERMANENTLY overlayed in its 2D plan diagram in order to be useful for more than a simply on screen design game.Īny architecture related plan should have visible main dimensions on it rather than approximate them from a measurement scale !Īnother feature to be better fixed as demanded for next release is to extend editing the dimensions in any object properties panel then automatically followed by updating its dimensions in the plan.

Typically, a router features a label on the back that says whether it’s a 24 GHz or a 5 GHz system. However, some don’t connect with a 5 GHz network, so be sure you know the network’s capacity before buying. Most smart switches connect with a 24 gigahertz (GHz) Wi-Fi home network, and others connect with either a 24 GHz or a 5 GHz network. By syncing with one of these systems, users can control the switch and the other connected smart home components (such as security cameras and thermostats). Most smart light switches sync with popular smart home systems, such as Alexa, Google Home, and Samsung SmartThings. When a lamp is plugged into the switch, the lighting can be adjusted by connecting the device via Bluetooth to a smartphone, Alexa, or another smart device.
