However, keep in mind that your mission in Spider Solitaire is to create entire sequences of consecutively numbered cards of the same suit. Sometimes, you’ll want to put a card onto a dissimilar suit just to move it out of the way so you can create the sequence you need to win. This means you can place a five of clubs on top of a six of clubs, hearts, spades, or diamonds. You’re only allowed to move a card onto another card if it’s one higher in rank. This is known as the “foundation,” and it’s where your completed sequences go. Leave enough room below the tableau for discard piles. All the remaining cards go in a stockpile at the very top of the tableau. Make sure the top card of each column is face up. You’re going to want to see each card, so place each card slightly lower than the card it’s lying on. However, make sure the first four columns have six cards, and the other six columns have five cards each. ![]() Shuffle the cards, and then deal out 54 of them in 10 columns, all in a straight line. Remove the jokers, which should leave you with 104 cards. To play Spider Solitaire, you’re going to need two decks of cards. That’s because you’ve just won the game, which is no small accomplishment when it comes to Spider Solitaire. Once you’ve successfully cleared the board of all cards, give yourself a pat on the back. The objective of the game is to arrange all the cards in a suit so that they go, in descending order, from the king all the way down to the ace.Īfter doing this, you’ll remove the sequence from the board and place it on one of the eight discard piles. You should probably play the Spider 1 suit and Spider 2 suit versions before you try your hand at Spider 4 suit.

It seems that Moo Gak is a lower ranking officer than the pair and Officer Ye doesn’t like that he is trying to take over the case. Moo Gak here is undercover and at this moment being watched by two other officers who are also undercover with him. I like how Cho Rim is concious of both parties in this situation and I’m definitely going to enjoy her character. Without either of them speaking Cho Rim gets the man to leave the shop after the woman. ![]() The woman leaves without her purse and Cho Rim gestures and points to the hat, telling him to give the wallet to the woman. While they are talking Cho Rim sees that the woman smells like a hospital and uses citrus handwash, the same scent coming from under a baseball cap behind the counter. While in the cafe, Cho Rim sees a woman who has lost her wallet asking the man on the desk whether he has seen it. It is 6 months later and Cho Rim is adorable, I think she is going to be a great female lead! I hope that his intentions are good, however why has no one told her the truth? She is still a witness and they would want her to get her memory back right? The police officer from the crime scene, who was also there when she woke up, seems to have adopted her. She also now has one green eye (the left one) on which she wears an eye patch because people look at her with scared expressions. It seems that her senses are bombarded with smells and the effects, she begins to panic and becomes worked up.Įun Seul, now Oh Cho Rim, doesn’t remember anything from before she woke up. She is a little dazed from waking up at first and then sees glowing effects that are the smells of things all around her. He says that the girl is the only witness.Īfter 139 days in a coma like state, Eun Seul wakes up. The police officer in charge (?) notices the mark and also latches onto the name Choi Eun Seul. Her parents were also found on the beach, the father having an odd burn or cut on his wrist. The music in this drama so far, my poor heart! Not to mention how good Yoochun is at crying… However, is the killer just going to go around killing every girl with the name Choi Eun Seul? He saw what she looked like, didn’t he?Įun Seol, the alive one, is still unconscious after 7 days of being run over. The fact that he is at the hospital does not look like it will bring good news. He has the same shoes and come on, that face has a kind of creepy psychotic look about it (which I’m sure means that this actor will be a good one). Her name is Seul Eun, the same as the other girl. ![]() Moo Gak (Yoochun), a very adorable older brother is at a hospital after receiving a phone call from his sister telling him that her school bus has been in an accident. ![]() I know it’s more dramatic to have her lying on the road and then for it to start raining, but why didn’t the person who ran her over get out of their car and help her the moment they stopped the car? Now he knows her name, he will try and kill her again? Finish the job later on? But why was in her house in the first place? Why her family? The intruder has the girl’s, Eun Seol, nametag from her school uniform. Oh my god, the girl ran out of the house, followed by the man and then she got run over! The slow motion and the music used at this point were very effective. You know something bad has gone down when they start the drama with a flashback!Ġ2:15 – The person in the girl’s (Shin Se Kyung) house house killed (?) her father too! I feel so tense right now!! The bad guy is in the house and she just entered it…Ġ2:40 – He shushed her, that’s always super creepy when bad guys shush! The opening credits are cool with the comic book effects.Ġ1:38 – Well, this is a scary opening! Is the mother dead? Park Yoochun and Shin Se Kyung have definitely impressed me! Overall, this was a wonderful opening episode, there were a few scenes I felt didn’t need to be repeated, however the characters and the visual effects, as well as the music are on point so far. I have seen a lot of high praise for this drama and I can’t take it any longer, it’s time to delve in haha~ ![]() 4/15/2023 0 Comments Ufo alien invasion registration![]() ![]() enders How could we fight off an alien invasion? This sort of scenario has been covered in various sci-fi works for many decades now, but we will never really know the outcome of such an event until it happens. Since such a meeting would be incredibly tense, the chances of events spiraling out of control are quite likely. There is also the possibility that humans could unintentionally spark aggressive actions from aliens. "To what extent alien life can curb their aggressive instincts (or else they will possibly self-destruct) is anybody’s guess," he added. "We have good reason to believe that aggressive instincts will be present in extraterrestrials," astrobiologist Pushkar Ganesh Vaidya has written. It may also be the case that aliens, like our own species, have developed the capability for both extreme violence and peaceful compromise. The same is probably may well be true for alien life. On Earth, at least, predatory animals tend to be the ones who have developed problem-solving abilities. After all, a species that cannot fight to defend itself or hunt is less likely to develop the capacity for exploring the unknown and taking the risks of space travel. It is quite likely they'd be capable of some aggression, as this kind of behavior is generally favored by natural selection, at least here on Earth. If they are millions or even billions of years ahead of us in development, the outcome of meeting them may not be in our favor. However such aliens look, many experts have also warned that they will likely be unpredictable. Robotic aliens are also more likely to make such long journeys, as they will be far more durable than any kind of life we currently know. "Cultural evolution will eventually result in methods for improving intelligence beyond those biological limits," he added. Dick, an astronomer and ex-chief historian for NASA has argued. ![]() "Because of the limits of biology and flesh-and-blood brains," Steven J. Yet other experts also suggest that such robots could be the aliens themselves. ![]() This might be for a variety of reasons, but the time required for long journeys and investment in life support systems are chief among them. Similar to how we do not risk human lives on more extended space exploration missions, aliens may adopt a similar strategy. While this is obviously fantasy, it does raise some interesting questions.įor example, what would aliens look like? Many thinkers in this field believe that our first contact with aliens will be with robotic probes or drones rather than living creatures. To this end, they mount an invasion but are defeated through various interesting tactics and extreme sacrifice. To this end, they begin to prepare Earth for a new colony. In this series, the ant-like aliens called Formics do not consider human beings sentient since they lack a "hive mind". This, for example, is the premise of the First Formic War Trilogy in Ender's Game series of novels written by Orson Scott Card and Aaron Johnston. Whether intentionally or by accident, an alien species may wipe us out, or perhaps worse, consider us as a resource to be harvested. If so, they will be vastly more powerful, and may not see us as any more valuable than we see bacteria," he later qualified. "A civilization reading one of our messages could be billions of years ahead of us. "If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans," Hawkings said in a 2010 documentary for the Discovery Channel. He believes that bumping into extraterrestrial life would be devastating for our species and planet. Some of the greatest scientific minds, like Stephen Hawking, have famously warned about not announcing our existence to the universe. While we can only know for sure if an alien species would be aggressive by actually meeting them, we can make some educated guesses about how such an encounter may turn out. It is probably worth exploring if we actually have anything to fear before we get into the nitty-gritty about potential defensive strategies for our planet. ![]() 4/15/2023 0 Comments Actio popularis![]() ![]() This would be the case if any natural or legal person could bring an action against substantial amendments to specifications.Īnd if “non-locals” were excluded from a right of appeal against changes to the specification, this would also offer the possibility of abuse. 1151/2012 that a Collective action – “actio popularis” – would have to be made possible. 49(4), second subparagraph, of Regulation (EU) No. ![]() ![]() BGH wants to exclude “actio popularis”Īccording to the BGH, however, it does not follow from Art. A corresponding action would consequently be considered admissible even if the national procedural rules do not provide for this in such a case (see ECJ, Oleificio Borelli v Commission 1992 GRUR Int. This requires an interpretation by the ECJ, the BGH ruled, because Union law sees judicial reviewability as fundamentally necessary also in relation to an act such as an application for amendment of the specification, which is a necessary stage in the procedure for the adoption of a Union measure. The prerequisite for this is always a “legitimate interest”. Accordingly, any natural or legal person has the right to opposition proceedings against amendments to the specification which are not minor. In German trade mark law, the requirements of Union law on the participation of persons with a legitimate interest in the procedure for the registration of protected geographical indications as well as in the procedure on applications for non-minor amendments to their specifications are implemented in the Trade Mark Act by the provisions of Sections 130(4), second sentence, and 133, second sentence, in conjunction with Section 132(1) of the Trade Mark Act. 6(2) of Delegated Regulation (EU) No 664/2014) opposition proceedings then do not take place (September 2019, C-785/18)). 53(2), second subparagraph, Regulation No 1151/2012 and Art. If the proposed amendments are minor, a simplified procedure is carried out in the member state and at Union level (Art. In principle, amendments to specifications are possible, but opposition procedures can also be conducted against them. Can any natural or legal person also rely on it? Or only economic operators who produce comparable products or foodstuffs to those for which a protected geographical indication is registered? And: Are “non-locals” excluded from claiming a legitimate interest from the outset? Appeal against changes to the specification Appeal against amendment of the specification: Who has legitimate interest?Īccording to the BGH, the success of the appeal depends on how the “legitimate interest” in Article 49(3), first subparagraph, and (4), second subparagraph, in conjunction with Article 53(2), first subparagraph, of Regulation (EU) No 1151/2012 is to be interpreted. ![]() Thus, the case came before the Federal Court of Justice (BGH), which submitted the term ” legitimate interest ” to the ECJ for interpretation. The applicant Hengstenberg filed an opposition against this, but failed so far, most recently before the Federal Patent Court however, an appeal on points of law was allowed (BPatG 2018, 30 W(pat) 36/15). In February 2012, the association of “Spreewälder Gurken” applied for an amendment to the specification at the German Patent and Trade Mark Office. The designation ‘Spreewälder Gurken’ has been registered as a protected geographical indication for unprocessed and processed vegetables in the Register of protected designations of origin and protected geographical indications since 19 March 1999. In a nutshell, the key question was: Who has a right of action and opposition proceedings against changes to the specification such as a geographical protected indication?

This confirmed that I had some problems with SteamVR installation and was not a matter of hardware. That’s why I’ve never been able to play such an awesome experience like Welcome To The Lightfields. For instance, in MeetingRoom.io and in Welcome To The Lightfields, I could see my Touch Controllers in VR inside the floor and I had no way to move them. This reminded me that I had a similar issue when playing some SteamVR experiences with my Oculus Rift. In my case, the controllers weren’t detected in any app, not even in Unity when developing for VR. Where to look to perform a quick calibration (sorry for the Italian language of my PC) There are anyway other tools that can help in configuring it properly. If games work this way, you can avoid getting crazy to have your VR controllers detected inside Room Setup and play happily your VR games, even if your Chaperone borders won’t reflect your real room configuration. Before doing that, please put your headset on the ground, in the center of your play area, so that the resulting Chaperone borders will give you a good experience. To perform a fast and rough room configuration, you can go into SteamVR settings and then choose the Developer Tab and look for the “Room and monitoring” section, where you can select a preset room configuration inside the drop-down menu and then hit the “Quick Calibration” button. If the answer is yes, well, you can survive even without launching Room Setup. So, the first thing to do if the various reboots didn’t work is trying opening a SteamVR game and see if there the controllers work (you can see and move them). Someone had this problem only happening in the Room Setup app, while in all the other applications, everything worked like a charm. Otherwise, contact HTC support to have your Vive fixed (good luck with that). If the headset does work on the other PC (like in my case), then there is some software problem with SteamVR. ![]() This way you can exclude some hardware failure. Try your Vive headset on another PC, if you can. So, another thing that you can try is verifying if the issue is due to some problems of the USB port that you chose: try disconnecting the Vive box from the current USB that it is connected to and try plugging it into other USB ports (try different setups, like front/back ports, USB 2/USB 3 ports, etc…). ![]() In lots of cases, it solves all the issues you can have with your Vive.īut sometimes, this is strangely not enough (as in my case). This is the most simple but also most effective advice. Shut down your Vive headset, controllers and Lighthouses and turn them on again.Unplug all the devices from the USB and plug them again.But don’t reveal it to others, because it is a top secret between we IT guys: So, I did the first solution that I advise you all. As you can see, the headset got correctly detected, while the controllers were reported as shut down… but this was not true So I launched SteamVR Room Setup, and it continued saying that my controllers were turned off when actually they were turned on. And when I put the headset on, I could see the grey intro environment, with all the controllers moving regularly. So I installed the Lighthouse stations, the Link box, and all the Vive stuff, then I launched SteamVR and I was pleased to see that all the icons in my SteamVR status bar were green. I bought my Vive to experiment with 7Invensun eye tracking and I was really enthusiast about trying eye-tracked UX. ![]() 4/15/2023 0 Comments Airserver windows download![]() ![]() Setup Type: Offline Installer / Full Standalone Setup DMG Package.Setup App File Name: AirServer-7.2.6.dmg.Mac Software Full Name: Airserver for macOS.Offers the best quality in mirroring and make sure of retina quality mirroring.Teachers can also use it to live stream their lectures for students.Provides support for an iPhone, Mac, Android, iPad, or Chromebook.Uses the BYOD solution to implement all the advanced functionalities.Got an interactive and user-friendly interface that is easy to use.Protects your personal photos and videos during transmission.Offers you drastically improved picture quality during mirroring.An ideal program that offers an advanced screen mirroring receiver.On a short note, AirServer is a marvelous application for screen mirroring.

Synth Definitions are referred to by name. Synth Definition files are created by the SuperCollider language application and are loaded into the synth server. Synths are created from Synth Definitions. Synths can have their own local controls that are set via commands to the server. They read input and write output to global audio and control buses. They can be addressed and controlled by commands to the synthesis engine. SynthĪ Synth is a collection of unit generators that run together. See RootNode and Default Group for more info. ![]() If the server was booted from within SCLang (as opposed to from the command line) there will also be a 'default group' with an ID of 1 which is the default target for all new Nodes. At startup there is a top level group with an ID of zero that defines the root of the tree. The Nodes in a Group may be both Synths and other Groups. The Nodes within a Group may be controlled together. A new Node may be added to the head or tail of the group. GroupĪ Group is a collection of Nodes represented as a linked list. The tree defines the order of execution of all Synths. Main Design Concepts NodeĪ Node is an addressable node in a tree of nodes run by the synth engine. The Unit generator API is a simple C interface. Unit generator definitions are Mach-O bundles (not to be confused with CFBundles). Synth definitions are stored in files generated by the SuperCollider language application. If MIDI is desired, it is up to the client to receive it and convert it to appropriate OSC commands for the synth engine. It is expected that the client will send all control commands. The synth server does not send or receive MIDI. The synth server and its client(s) may be on the same machine or across a network. Patching between modules is done through global audio and control buses.Īll commands are received via TCP or UDP using a simplified version of Open Sound Control (OSC). All running modules are ordered in a tree of nodes that define an order of execution. Effects processes can be created and patched into a signal flow dynamically at scheduled times. While synthesis is running, new modules can be created, destroyed and repatched, sample buffers can be created and reallocated.

However, the costs of TLS equipment are usually high, and multiple scan locations may be needed to minimize scan occlusions in scenes where terrain and crash are complex. Enormous scene details can be scanned and captured in a relatively short period of time. Over the past two decades, the potential of terrestrial laser scanning (TLS) has been validated in various crash scene scenarios. Close-range photogrammetry, which emerged around the same time in accident investigation, is able to recover accurate two-dimensional (2D) and three-dimensional (3D) measurements and diagrams by taking overlapping photographs from different viewpoints around crash scenes. The ability to collect digital data off the roadway eases investigators’ exposure risk to traffic and reduces entire surveying time. In order to automate accurate documentation of distance and angle measurements, total stations have started to play a key role at crash scenes since the early 1990s. While relatively low cost, these methods have limited efficiency to document measurements and pose safety risks to investigators due to possible exposure to traffic. They use mechanical measurement tools such as tape measures and roller wheels to acquire baseline measurements and delineate crash scene diagrams. Traditional coordinate and triangulation methods have long been adopted by investigators at a crash scene. Crash scene investigation and reconstruction are considered crucial being part of the major concerns in traffic incident management (TIM). Major lessons learned for real-world quadcopter sUAS flight design in windy conditions for crash scene mapping are also documented.Ī motor vehicle crash can cause considerable economic loss, serious bodily injuries and loss of human life. Simulation results suggest operating the simulated quadcopter type when wind speed is less than 11 m/s under light to moderate turbulence levels for optimal flight performance in crash scene reconstruction missions, measured in terms of positional accuracy, required flight time, and battery use. Both statistical and visual analytics are performed. Average 3D error, standard deviation, battery use, and flight time are used as statistical metrics to characterize the wind impacts on flight stability and endurance. Incremental increases in wind speed, direction, and turbulence are conducted. This simulation uses typical flight capabilities of quadcopter sUAS platforms that have been increasingly used for traffic incident management. To bridge this gap, commercial and open source sUAS flight simulation software is employed in this study to analyze the impacts of wind speed, direction, and turbulence on the ability of sUAS to track the pre-planned path and endurance of the flight mission. ![]() Wind is a typical environmental factor that can cause adverse weather, and sUAS responses to various wind conditions have been understudied in the past. However, auto crashes tend to occur under adverse weather conditions that usually pose increased risks of sUAS operation in the sky. Small unmanned aircraft systems (sUASs) have emerged as promising platforms for the purpose of crash scene reconstruction through structure-from-motion (SfM) photogrammetry. ![]() |
