![]() Policy makers-not just in the United States but in all nations with nuclear weapons-have abdicated their responsibilities to curb and eliminate the threat posed by their nuclear weapons. Who really has been in control all these years? No one. In other words, Oppenheimer had only provided the weapon and had no responsibility for its use-nor control over how it might be used again. It was he, Truman as the president of the United States, who made the decision to use these weapons. There is a remarkable scene in the Oval Office in October 1945, when Oppenheimer tells Truman that he has blood on his hands, after which the president looks at the scientist with disgust and tells him that he had nothing to do with the bombing. (A year later, the weapons were put under civilian control, eliminating the military’s authority over the weapons.) ![]() The scene in which the two bombs that would be detonated over Hiroshima and Nagasaki are boxed up and handed over to the military hammers home the point that the scientists were no longer in control of these weapons-literally and figuratively. This belief also proved to be short-lived. While others were not so sanguine, Oppenheimer expected that he and other scientists who built the bomb would have a hand in future US policy. In early July 1945, 70 Manhattan Project scientists working at the University of Chicago Metallurgical Laboratory signed Leo Szilard’s petition to President Harry Truman arguing that if the United States used these weapons on Japan it would “bear the responsibility of opening the door to an era of devastation on an unimaginable scale.” Robert Oppenheimer, director of the Los Alamos Laboratory during the Manhattan Project, repeatedly argued that the only way to prevent an arms race with the Soviet Union was to brief the Soviets on the Manhattan Project before the weapons were used and propose a treaty prohibiting such weapons. "We look at everything that connects into storage, so we'll cover things from battery backups and racks, all the way out to thin clients. Despite its name, covers the entire spectrum of the storage market, including computing system performance. Kevin has spent more than a decade in editorial positions in the tech industry and is currently lab director at. And the fact that they are maintained and published by a non-partisan consortium is critical to credibility." "Benchmarks aren’t perfect, but SPEC/GWPG does a good job of making them well-rounded. I use SPECviewperf as my standard for benchmarking workstation GPUs, as it primarily stresses the graphics subsystem. SPECwpc is especially nice if the review is for a system that is targeted at a specific vertical, as it provides composites for six different application categories. ![]() I use the former as my baseline benchmark when reviewing systems. "The two I rely on the most are SPECwpc and SPECviewperf. For example, if you only view models in ‘shaded and edges’ mode, just check out that specific score."Ī 25+ year veteran of the computer graphics industry, Alex authors Jon Peddie Research’s Workstation Report and does reviews for the TechWatch newsletter. The overall graphics composite scores are useful, but you can get a much better understanding of how performance relates to your specific workflows by looking at individual scores for different render modes. "One of the best things about the SPECapc benchmarks is they allow you to drill down into the details of 3D graphics benchmarking. Importantly, the results are consistent (so the benchmarks are reliable) and the benchmarks run inside actual CAD applications so they better reflect what the CAD user would experience in the real world. ![]() "At Develop3D magazine, we find the SPECapc benchmarks (both SolidWorks and PTC Creo) very useful because they provide a detailed view of graphics performance. ![]() As part of my review, I need to include objective performance metrics using tests that are readily available so that the same test could be run by someone else in order to validate the results I obtain."Īs managing editor of Develop3D, Greg has used SPEC/GWPG benchmarks in reviews of hundreds of CAD/CAM workstations and graphics cards. "I feel that SPEC/GWPG benchmarks add a greater level of detail and credibility to my reviews. ![]() "I use SPECviewperf to test graphics performance of workstations and GPUs, SPECapc for SolidWorks to test overall performance of workstations running typical MCAD applications, and SPECwpc to test overall performance of workstations. Here's what they had to say:ĭavid is one of the longest-time users of SPEC/GWPG benchmarks, dating back to when Digital Engineering (formerly Desktop Engineering ) was a print-only publication. We talked to some reviewers who are long-time users of SPEC/GWPG benchmarks to find out which benchmarks they use and why they use them. If there is a review of a professional workstation or graphics card within an online or print publication, the reviewer is likely to quote results from a SPEC Graphics and Workstation Performance Group ( SPEC/GWPG) benchmark. So an external system can also be an implementation detail left out of the UC diagram. You can segment the line by holding down button 1 down on the line and moving before releasing. This will create a straight line between actor and use case. To join a use case to an actor on the diagram use button 1 click on the association icon on the editing pane toolbar (). They are also great storyboard tools for user meetings. It depends on what role the system plays and how it is related to the use case. it would not add any observable result of value for the stakeholders of the system under consideration). ArgoUML allows you to draw use case diagrams. The system The actors (those who interact with the system) The use cases (what the actors can do) Advantages of Using a Use Case Diagram Software Use Case diagrams are used to identify the primary elements and processes that form the system. Yes, an external third party system can be an actor. But this one should in principle not be considered as an actor, if the DBMS is a design decision that is not relevant for the use case (i.e. So IMHO, this secondary actor should better be called Cardholder's bank instead of SWIFT for a higher accuracy and a more general solution.įor the sake of completeness, let's take another example: a third party DBMS could also be considered as an external system. In reality, SWIFT is only a network used to reach the cardholder's bank. This interaction would most probably be mentioned in the use case requirements (regardless of how the ATM software would be implemented). It is important to note, though, that UCDs are fundamentally different from sequence diagrams or. That is, rather than merely representing the details of individual features of your system, UCDs can be used to show all of its available functionality. Actor is shown in the form of stick man or rectangle with icon, that is decoration view. Procedure for Creating New Diagram: Select from the model explorer or diagram area an element to contain the new diagram. create Actor, click Toolbox -> UseCase -> Actor button and click the position where to place Actor. In plain text this means that in your example, SWIFT could be a good candidate for an actor: the ATM has to interact with SWIFT to ensure the money is withdrawn from the holder's bank. UML Use Case Diagrams can be used to describe the functionality of a system in a horizontal way. Editing Elements and Diagrams Organizing Model Structure Editing Elements and Diagrams Creating New Diagram StarUML supports 11 UML diagram types. Specification of its associated UseCases. Instead a particular role of some entity that is relevant to the Use case diagrams can help professionals visualize systems in many fields, including sales, software development, business and manufacturing. To quote a (non binding) note of the UML standard:Īn Actor does not necessarily represent a specific physical entity but A use case diagram is a tool that maps interactions between users and systems to show the interactions between them. Yes, actors CAN be human users or external systems.īut not all the external systems SHOULD be actors.

In fact, not only is the ratio too great, much of the paper used in offices winds up in landfills anyway. While recycling is a way to combat some of these effects the ratio of manufacturing and paper demand in comparison to how much is being recycled barely scratches the surface of what is needed to help our environment recover. The manufacturing of paper products is known to have disastrous effects on the environment including the production of greenhouse gases, global warming, and causing deforestation. One of the most prominent reasons why organizations want to go paperless is because it is good for the environment. Here are some of the most standout advantages of transitioning to minimize your organization’s reliance on paper and making a paperless office. ![]() There are multiple benefits to going paperless for your business both internally and externally. If you decide to make the switch and transition to make your office paperless there are many things that you, your team, your organization, and the environment can gain from your efforts.
![]() Link Skills improve at Level 120 (Skill Level 2) and in GMS again at Level 210 (Skill Level 3). Some Link Skills may have different effects for the character with the linked version 70, a Link Skill can be shared with another character and both characters will gain the effect of the Link Skill. Link Skills are mainly passives, however, there are a few buffs too. Link Skills are unique to each class and can be shared to another character on the same World. You can tier up by using Honor EXP to reset your Inner Ability and resetting will not lower your tier Link Skills: Like Potentials, there are different tiers, Rare, Epic, Unique, and Legendary. Inner Abilities are stat bonuses that work similar to Item Potentials but for your character. Inner Ability is located under the Character Stat UI and is automatically unlocked at Lv. : For Beast Tamer, you will continue to gain SP up until Lv. Choose STR only if you are creating a Buccaneer and DEX only if you are creating a Corsair : For Explorer Pirates, you will have the choice between Auto Assigning to STR or DEX. 200, you continue to evenly distribute your AP The game will let you know when you've reached the requirement for the Multilateral skills. : For Xenon, distribute your AP evenly between all 3 stats using Auto Assign. It is highly recommended to use Auto Assign for all your AP : Zero does not have Job Advancements and instead unlock new skills by levelling up SP and AP Distribution:Īll newly created characters (except Beast Tamer) can max all of their 1st - 4th Job skillsĪ tip for allocating SP is to first put 1 point in everything and then start maxing skills by prioritizing skills that require the least SP to reach Master Level, then passives with useful stats like %Final Damage, %Damage, %Max HP, or %Damage Reduction, then buffs, and lastly attacksįor AP, you gain 5 AP every level up and most classes gain 5 AP each Job Advancement from 1st to 4th. ![]() For mobbing or Legion, you can use Bear/Leopard/Cat instead : Beast Tamers do not have Job Advancements and instead unlock new skills by levelling up and allocating enough SP into an animal tree.

Some brief advice before starting, there is no need to worry about dailies and bosses until you've reached Lv. ![]() If your broadband contract started after March 2019 and you're with one of the providers that has signed Ofcom’s voluntary code of practice (BT, EE, Plusnet, TalkTalk, Utility Warehouse, Virgin Media and Zen Internet), your provider must give you a minimum guaranteed speed when you take out a new contract. Start by providing evidence of your internet speeds – it's a good idea to keep a diary of interruptions and to regularly use the speed checker tool to build up a true picture of your service. We suggest calling your internet service provider (ISP) as a first step to see what it can do. However, if you've done everything you can to speed up your connection and you're still getting a lower speed than you were promised, your broadband provider may be in breach of contract. If your speeds are significantly less than you expected, there are steps you can take to improve things – get started by checking our advice on Speed up slow broadband. Tech tips you can trust – get our free Tech newsletter for advice, news, deals and stuff the manuals don’t tell you What you can do if your broadband speeds are slow The results also only show the speeds you're getting on the device you're using for the test – the speed your provider is delivering to your home may be higher, especially if you're performing the test wirelessly at some distance from your router. To build an accurate picture, we would suggest you run several tests during a single week, in peak use time (between 8pm and 10pm) and during off-peak times. However, if you use your broadband connection for video calls or online gaming, keep an eye on the upload rate, too, as it's essential for both. The upload speed shows the rate that data is transferred from your device to the internet – how quick it is to upload a photo or document to an email, for example.ĭownload speeds are usually of more interest, as most tasks require you to download information, for example searching online for information. ![]() The download speed shows the rate at which data is transferred from the internet to your device – how quick it is to access a newspaper article online or stream music, for example.This is needed for applications where timing is everything, such as interactive video games. More responsive connections are those with a low number of ms (meaning they take less time to respond). Response time is measured in milliseconds (ms) and shows how quickly you get a response after you've sent out a request.The tool measures the response time – also known as latency – of your broadband connection, as well as your download and upload speeds. What do the broadband speed test results show? You should also make sure nothing else is using your internet connection or running on your computer when you do the test. If you need to test wirelessly, get as close to your router as possible. How to use our broadband speed checkerįor the most accurate results, use an ethernet cable to connect your computer to your router before running the test. In addition you could check internet speed with a network speed test as well to compare wireless and wired connectivity.We explain how to use the speed checker below – and if your broadband isn't as fast as it should be, we give you some simple steps you can take to speed up your connection. You can run a WiFi speed test on all your devices to idenitify the ones that have a strong WiFi signal and the ones that don't. Selectively enabling and disabling your WiFi hotspots can quickly help identify the problematic device. Maybe your device is not connecting to the correct WiFi hotspot, so it must go through a thick wall. If the interet speeds differ on your connected devices, however, the poor connectivity is likely either due to a local misconfiguration or device capabilities. If the internet speeds are the same for the weak and strong signal, it's likely an ISP issue. Just run multiple tests, one close to your WiFi Hotspot and one in the place where you're having issues because the signal strength diminishes. So to figure out if your connectivity issues are due to your ISP, your wireless connection or a local router issue running a WiFi Test will give you the insights you're looking for. Most of the devices on your home network today are not connected with a wired connection anymore. Running a WiFi Speed Test is the right solution for most people if they encounter connectivity issues as they are usually internet speed related. ![]() What is Jitter aiming you say?

![]() Marlon Blandon is thread mills product manager with Emuge Corp. Understanding how the values can affect the manufacturing process is an important consideration. 2 732 Taper pipe tap drill sizes NPT and NPTF apT Thread Drill size form size. Roll form tapping displaces metal from the hole walls to form the threads so cutting tap drill will leave too much material in the holeĬhoosing the correct tap drill size for an internal threading application is not as simple as looking at an outdated tap drill size chart. Drill size decimal equivalent & tap drill chart decimal equivalent chart. Material is being displaced and formed instead of cut, requiring the pre-drilled hole to maintain the correct amount of material to be formed into the taps thread profile. A 7/16-14 UNC roll form thread will require a 10.25 mm (0.4035 in.) drill size. Roll form threads require tap drill sizes that are larger than those specified for cut taps. ![]() In some harder materials such as nickel alloys, stainless steel, and hardened steels, it is possible to tap with as little as a 50 per cent of thread value. As a general rule, the tougher the material, the less the percentage of thread required to meet design requirements. But that two per cent reduction in thread percentage will reduce torque on the cutting tool and increase tap tool life. The slightly larger drill diameter still provides a 73 per cent of thread value, which is more than acceptable. Tap life is greatly reduced in an effort to theoretically increase thread strength.Īs an example, a 7/16-14 UNC cut thread is usually denoted as a letter “U” 9.3 mm (0.3680 in.) diameter drill on most older tap drill charts that equates to a 75 per cent value for percentage of thread, but a 9.4 mm (0.3701 in.) drill might be a better choice. According to some, 100 per cent thread specification is only five per cent stronger than a 75 per cent thread specification, but requires three times the torque to produce. It is important to realize thread strength is not directly proportional to per cent of thread. By increasing the pre-drilled hole diameter, the machinist can increase the life of the tap by reducing the amount of force required to form the thread. Many tool manufacturers suggest using a percentage of thread values between 60 and 70 per cent for most pre-drilling applications. Making the correct tap drill size choice will affect the machining operation. High speed drills typically cut larger actual hole sizes than carbide drills. Many tap drill holes are now being created with high performance carbide drills and these carbide drills generate more accurate holes than high speed steel drills. Another reason why some tap drill charts are outdated is that most drills for producing tapped holes were high speed steel or cobalt when the charts were created. The percentage of thread values that older tap drill charts provide is higher than needed in most cases. To reduce the risk of thread failure, the design engineer was often cautious and specified high percentages of thread height in tapped holes. While slower than that for tapping most other materials, this range has been. We recommend a tapping speed of 10 to 13 sfpm for both turning into and exiting the tapped hole. Inadequate or excessive speed will result in tap failure and/or shortened tap life. Not intentionally of course, it is just that most machinists are using outdated charts designed back in the 1950’s when high speed drills were the norm. Tapping speed is critical for cutting threads in titanium alloys. One of the most common mistakes a machinist makes when tapping a hole is using the wrong size drill. ![]() To calculate tapping drill size for metric threads subtract the pitch from the major diameter, Select the next larger standard drill size.Are you really getting the best results from your taps? Avoid common mistakes. eg for an M5x0.75 thread the tapping drill is 5-0.75mm = 4.25mm.įor Imperial (inch) threads the tapping drill size is calculated in the same way, diameter minus pitch. As a rule of thumb, for Metric threads, the tapping drill can be calculated by subtracting the pitch from the diameter of the thread. |
