Half of the platform will be inside, with the other half outside the facade. Other than the indoor decks, smaller revolving platforms resembling balconies at the margin of the deck allow people to enjoy more views from an open air space. The inspiration for the observation decks is the ancient Hanging Gardens of Babylon which is why they will be decorated like gardens. When standing on the observation deck, people can enjoy 360-degree views of the city. The Pinnacle Room and Observation Deckĭubai Creek Tower won't have one but ten observation decks in the oval-shaped structure close to the top of the tower. An estimated cost of AED 3.67 billion, equivalent to 1 billion USD, costs to pull off this project. Unfortunately, due to the coronavirus pandemic, construction was halted, pushing completion to 2022 or beyond.ĬSEC, China State Engineering and Construction contractors responsible for numerous mega-tall skyscrapers in China, were reported to be involved in the construction of Dubai creek tower. If the project were not put on hold, the tower would have been completed by 2020. The Dubai Creek Tower comprises a slender core structure that makes its construction much faster than a standard skyscraper like the Jeddah Tower. In May 2017, the foundation work had reached completion, and construction of the project above ground commenced. Later that year, in October, the preparatory work had begun, and about 170,000 cubic meters of soil were removed to make room for the tower's foundation. Various international firms of architecture globally submitted about six design proposals, but the Ruler of Dubai chose the one by the architect Santiago Calatrava.īy July 2016, critical tests for wind and seismic factors were completed to determine the height of the tower. Developer Emaar is responsible for the Burj Khalifa and is the largest real estate developer in Dubai. The development of Dubai Creek Harbour is under Emaar Properties in association with Dubai Holding. A tower this tall can serve as a huge tourist attraction, increasing its real estate value of the property, making the district a site to visit. While the heart of the complex was originally planned to be a pair of twin towers, the idea was eventually replaced with the Dubai Creek Tower. These cables are spread out on the ground to give the tower the stability it needs while standing over 1000 meters high. If you consider the cable arrays which anchor the building on two sides, you can see some resemblance to ribbing lily leaves. The architect identifies his inspiration for the Dubai Creek Tower to be the natural form of the desert lily, which was also the basis for the footprint shape of the Burj Khalifa. If you've not heard of him before, you're probably familiar with some of his past projects like the Olympic Athletic Center of Athens, the World Trade Center Transportation Hub, the Turning Torso, and The Chicago Spire. The design of the Dubai Creek Tower is a work of the Spanish-Swiss architect Santiago Calatrava Valls. Plus, the antenna situated on the peak is meant for broadcasting. About 20 floors will contain hotels, restaurants, and residences. The Dubai Creek Tower will primarily be a site for observation decks or sky gardens. Nevertheless, most public media and the Emaar Properties developer will probably refer to it as the tallest building globally despite having a form different from typical sightseeing towers. The CTBUH criteria are not accepted by everyone, which makes the issue controversial. Unfortunately for the Dubai Creek Tower, less than 30 percent of its height will feature habitable floors. This is because the Council on Tall Buildings and Urban Habitat (CTBUH) holds that a structure is only considered a building if at least 50% of its height is habitable. However, much dispute has arisen about whether the Dubai Creek Tower will be recognized as the world's tallest building. If the Dubai Creek tower rises beyond 1300 meters, it will undoubtedly become the world's tallest building and manmade structure, even taller than the Jeddah Tower of Saudi Arabia, which is estimated to reach a height of 1008 meters. The video also implies that 5 Dubai Creek Towers could equate to 8 times the Burj Khalifa, which would take us to about 1345 meters. With this information, we can estimate that the tower will reach a height of 1300 meters. A video released in Dubai Mall in 2017 displayed that if the tower were stacked on itself eight times, it would reach around 11 kilometers.

In most cases, therapists need a license to practice their services. Therapists are most commonly licensed mental health counselors who provide treatment through talk therapy, using psychological methods such as cognitive behavioral therapy or existential therapy. “Therapist” can be used to describe a broad range of careers, including psychologists, mental health counselors, social workers, and even life coaches. What is a therapist?Ī therapist is a professional trained to provide mental health and behavioral treatment, rehabilitation, and support for those who need it. If you have ever considered becoming a therapist, this article will help guide you through whether this is the right career path for you. Becoming a therapist can be a rewarding career if you value skills like empathy, listening, and understanding psychological frameworks. In fact, the job outlook for mental health counselors between 20 is 22 percent and much faster than the average of all occupations (5.3 percent). It’s also a career whose role in society is in high demand since the pandemic and other global tragedies may have heightened the need for social and mental support.

Ever had a full blown tantrum that would seem more appropriate for a five year old than a forty year old? Ever find yourself back in an old power struggle you had years ago when interacting with someone who reminds you of a family member, or when visiting family you haven’t seen in a while? There are times where you might regress back to a younger self-state than you’re chronological age. If you notice that somatically you lean over, lower your voice or hesitate when engaging with others, you can teach your body to keep going, speak up and stand tall- and notice how empowering it is to try a new way of being. You can also do this by expanding your body’s bandwidth for emotions and change how you interact. One of the ways to unravel the shambles of shame is catching yourself when your mind starts spewing negative, shame filled thoughts, and replace them with more appropriate ones. You may also carry shame about your body, and this impacts how confident and forward you are regarding expressing and asking for intimacy, physical contact and how present you are when you have sex. Notice if you hunch over when you’re asking for that promotion, if your voice quivers when telling that child to stop hurting yours or if you doubt yourself when presenting your work at a conference. Shame has a way of digging itself deep on the mind and body it impacts how we carry our bodies, our muscle tone and the stability in our voice. Shame expresses itself in may ways the way you interact with others, the kinds of relationships you believe you’re deserving of, how you speak up in the workplace, ask for that promotion and how you parent you kids and set boundaries. Often, if you were ignored, hurt or shamed as a child you will carry shame as an adult. It’s an emotion that distorts your entire identity, making you believe you’re damaged, no-good and unworthy of love and goodness. Shame makes you truly believe that you’re bad at your core. Your disappointed or anger may be with the world, society, god, or with some other form of construct that “should have” protected you- and you’re wondering “how was this “allowed “to happen” and “why was I not protected?”… and in your healing you'll slowly reconstruct a sense of safety and trust with personalized experiences and resources. …and your healing will be about slowly rebuilding trust in the universe as you heal. Sometimes this isn’t about person, but rather, sadness that god, society or the world didn’t protect or defend you.

The drop was short - from a coffee table to the floor - but it heavily damaged the drive. Advanced Data RecoveryĪnother business customer of ours accidentally dropped her Western Digital My Passport external hard drive. While there were no mechanical issues and no cleanroom was required, this particular job came with a degree of difficulty due to the drive’s firmware issues. All of the data was successfully recovered. Using specialised equipment, Drive Rescue was able to work around the bad sectors and repair the corrupted firmware modules. A simple diagnosis revealed thousands of bad sectors and some corrupt firmware. The disk would spin, but none of the files could be accessed. We had a customer whose 2TB Seagate Expansion external hard disk was no longer being recognised by their computer. No cleanroom was required, nor were there any firmware or mechanical issues to slow down the process. We knew this could be completed within a predictable amount of time. But the worst was that they lost four year’s worth of cherished photos.ĭrive Rescue recovered everything for him, including peace of mind. This innocent mistake caused him to lose everything, including their Word files, Excel files and PDFs. One of our customers accidentally installed Windows 10 over their existing operating system. Here are three quick case studies to help clarify what each category does: Basic Data Recovery So, what is the difference between Basic, Standard and Advanced recovery jobs? It comes down to the complexity of the job. Once the device is in their pocession you automatically become part of an elaborate sales process - a process which once entered into many customers don’t feel comfortable with. Instead, they will give you a “price range” and request that you send the device to their premises. However, they won’t divulge this to you over the phone or thru email. Other data recovery companies also have a fair idea of how much your data recovery job is really going to cost. The price we quote you over the phone is usually the price we stick to. Therefore, using our experience and after a short few questions about your device - we believe it’s only fair that you’re provided with a recovery price upfront and not just a price range. More likely than not, we’ve already recovered from a device similar to yours before. We deal with brands such Seagate, Western Digital, Toshiba, Micron, Lite-On Samsung and HGST on a daily basis. Storage devices are not that different from other technology products in that certain models experience commonalities in their failure modes. How Can We Give You a Price Before Even Seeing the Drive? The exact price depends on what type of recovery you need, which tends to fall into one of three categories: This way, you know what you’ll pay before we begin work. We will give you an exact price over the phone or email for most data loss situations - even before we even see your drive. While other data recovery companies will only quote you a price range, Drive Rescue operates an upfront pricing policy.

When my houdini is too far gone, I will certainly be replacing it. When I've taken this jacket on multi-pitch climbs, I've stayed away from clipping it to my harness in fear of pulling against it too hard and having my layer tumble down the wall. The clip loop is cute but delicate and unnecessary in my opinion. The high-zipper with the hood is excellent at keeping my hats from getting blown off my head on ridges. The chest pocket is just the right size for a phone and keys for a quick run. I like to layer it with my rain jacket for more wind-pro or in cold rain, or chilly snow activity days.

Basically, what's your stack? Has that changed over the 15-20 years you've been doing this?Ī: DF is some combination of C and C++, not in some kind of standard obeying way, but sort of a mess that's accreted over time. Our conversation below has been edited for clarity. If you want more, we also spoke with Tarn on the podcast. I reached out to Tarn Adams to see how he’s managed a single, growing codebase over 15+ years, the perils of pathing, and debugging dead cats. Up until now, he’s relied on donations to keep him going, but he’s currently working on a version with pixel graphics and a revamped UI that will be available for purchase on Steam. He writes all the code himself, although his brother helps out with design and creates stories based on the game. For the first four years it was a part time project, but since 2006 it’s been full time. The entire game is product of one developer, Tarn Adams, aka Toady One, who has been working on Dwarf Fortress since 2002. And it all takes place in an ASCII interface that looks imposing to newbies, but feels like the text crawl in The Matrix: craftsdwarf, river, legendary megabeast. Individual dwarves have emotional states, favorite gems, and grudges. The simulation runs deep, with new games creating multiple civilizations with histories, mythologies, and artifacts. It’s a free game where you play either an adventurer or a fortress full of dwarves in a randomly generated fantasy world. This is the endgame content, expect many miners to also perish in pursuit of dwarven greed.Īlso the reason why the alert for adamantine confused you is you likely saw a cavern floor tile of adamantine that happened to be poking out of the cluster from the z level blow but is obscured by the magma, if you moused over the edges of where it alerted you, it will say "adamantine cavern floor" meaning below is a block of adamantine.Dwarf Fortress is one of those oddball passion projects that’s broken into Internet consciousness. You will want the military airlock setup with fortifications because some of the things you unearth from the cluster will wipe out entire squads of legendary melee dwarfs, ranged is the safest way to eliminate them but sometimes you may deal with creatures that will even kill a few markdwarfs. The artifacts cant be melted but you can make them symbols for your monarch which is how you satisfy the symbol demand and gear retrieved off the Angels can be melted down and repurposed. Once you drain a level you can start mining all the gems out on that floor however there are other things that can be found in these pockets, Angels of the gods equipped with divine metal armor/weapons, devils, fiends, demons and divine metal artifacts worth incredible amounts of value. To frack them you want to find the top of the cluster and setup a military airlock making it so theres only one way into and out of the cluster then you want to start channeling randomly into the top of it, the Cluster is filled with various pockets, most will contain magma and water that may also have open spaces between z levels, you will want to probe for these pools and then use a screw pump above to empty out the pockets. If you keep going further into them you will eventually find adamantine spires that follow the cluster down into the sea. In the magma sea you will discover gem clusters containing some of the most valuable gems, similar to smaller clusters you may have seen in the cave layers but these clusters are massive and extend down into the magma sea. The unique metals are divine metals, forged by the gods in your world during a time before time.

From this practice, it seems that the physical optics method might prove to be a rather economical and effective approach to design and select appropriate ACRs in field deployment.īalanis CA (1989) Advanced engineering electromagnetics. The field data agree with the theoretical analyses. To verify the physical optics analysis results, we collected ENVISAT data from a variety of deployed ACRs in the Yan-Huai Basin, China, and derived their reflectance characteristics. The analyses indicate that under vertical polarity, among the three types of ACRs, the rectangle trihedral ACR is the most tolerant to its deploying surroundings. Adopting radar cross section (RCS) as the measure of ACRs’ detectability, we examined the relationships between the ACRs’ RCS under vertical polarity with various parameters including the radar incident angles, width and heights of the ACRs and the azimuthal angles. The current study attempts to tackle the issue from a physical optics perspective. The cost and difficulty of deploying ACRs in the field, however, render comparison among the three types rather impractical, if not impossible. Among them, dihedral, rectangle trihedral, and pyramidal ACRs are the most commonly employed. Many different geometric types of ACRs are designed to achieve maximum detection. Apparently, the detection and extraction of ACRs on remotely sensed images would be of utmost importance. The measured results reveal good accordance with the simulations, and both demonstrated that the designed metasurface corner reflector obtains tremendous RCS enhancement performances in a wide-angle domain (−50°–50°) for both TM and TE polarized waves.Among many of the differential interferometric synthetic-aperture radar technologies, artificial corner reflectors (ACR) are widely used in monitoring earthquake deformation and urban subsidence due to their relative stability on synthetic-aperture radar (SAR) acquisition. To validate the RCS enhancement performances, the mono-static RCS of the designed metasurface corner reflector is measured. The simulated results indicate that in the designed incidence directions, the reflected waves are all opposite to the incidence wave for both TE and TM polarized waves. As an example, the metasurface corner reflector consisted of two different phase gradients operating over the X-band is designed to realize wide-angle RCS enhancement. To derive a uniform mono-static RCS in a wide incidence angle domain, the flat metasurface corner reflector is decomposed into several regions with different areas, which are designed for RCS enhancing under wave incidence in different incidence directions. This guaranteed a radar cross section (RCS) enhancement in the vicinity of this incidence direction. Through designing the related gradient phase, the propagation direction of the reflected electromagnetic wave is just opposite to the propagation of the incidence wave based on the generalized version of the reflection law. In this paper, a wide-angle flat corner reflector based on the multiple phase gradient modulated metasurface is proposed and demonstrated. |
