What I didn't realize, though, is just how powerful this tool can be for certain purposes. I'm new to focus stacking in general, and assumed it was meant to bring as much of an image into focus as desired, while allowing for wider apertures in order to not worry about softness due to diffraction limiting while stopped-down. With this firmware upgrade, Olympus has brought not only focus bracketing to the E-M1 but in-camera focus stacking as well, letting the camera take the focus sequence and then do all the laborious stacking work for you!įocus Stacking "level 5" is my favorite setting from this first batch, as seen below. (In a way, it's kind of like shooting with a range of different exposures and then stacking those in post for a classic HDR look.)įor several years now many cameras have handled HDR stacking "in-camera", saving you the trouble of going through the motions after the fact. It's a matter of taking the in-focus areas from each shot and bringing them all together in a single image. Focus bracketing is a well-known photographic technique by which you take shots at multiple focus points and then "stack" them in post-processing after the fact to increase the total depth of field. (Scroll on down if you'd rather see the 6 sample images first!)Īs macro shooters know, depth of field becomes extremely shallow at macro distances which can make it difficult if not impossible to keep a 3D subject entirely in focus, even when the lens is fully stopped-down for maximum DOF (that's why you'll often see macro lenses with tiny minimum apertures of f/32). This feature is versatile enough to warrant a more in-depth article on the subject, but I couldn't wait to load up the new firmware and take a few shots for a quick post. Olympus recently released a major firmware upgrade for both their flagship E-M1 as well as their enthusiast-grade E-M5 II camera, and both got a whole host of cool new features including focus bracketing, but the E-M1 was the only OM-D to receive in-camera focus stacking.

Cohen's suggestions should only be seen as very rough guidelines. ES formulas and Cohen's suggestions (based on social science research) are provided below. Specifying an effect size can be a daunting task. Therefore, to calculate the significance level, given an effect size, sample size, and power, use the option "sig.level=NULL". functionįor each of these functions, you enter three of the four quantities (effect size, sample size, significance level, power) and the fourth is calculated. Some of the more important functions are listed below. The pwr package develped by Stéphane Champely, impliments power analysis as outlined by Cohen (!988). Given any three, we can determine the fourth. power = 1 - P(Type II error) = probability of finding an effect that is there.significance level = P(Type I error) = probability of finding an effect that is not there.The following four quantities have an intimate relationship: If the probability is unacceptably low, we would be wise to alter or abandon the experiment. Conversely, it allows us to determine the probability of detecting an effect of a given size with a given level of confidence, under sample size constraints. It allows us to determine the sample size required to detect an effect of a given size with a given degree of confidence. Power analysis is an important aspect of experimental design. When someone uses their computer to send a message through this type of network, all of the connected computers are aware of this action. This creates one channel for communication throughout the network. Drop lines are the cables that connect to the primary cable, also known as the bus, while taps are the individual connectors. Bus network topologyīus network topology is a foundational method that many network administrators use to connect all of the devices or nodes to one primary cable with various drop lines and taps.

Some of the advantages of using point-to-point network topology include: Point-to-point network topology is common in computer networking, computer architecture and telecommunications systems. The two devices could be two computers, servers, routers or switches connected to each other with a cable. This type of network topology involves connecting two nodes or devices using a common link. Point-to-point network topology is the simplest method. Here's an overview of each of these seven network topology types to help you get started: 1. Which one you choose to use may depend on an organization's size and specific needs. There are seven primary network topology types. Related: What Is a Network Diagram? (Plus How To Create One) 7 network topology types Therefore, network topology defines the virtual shape, layout and structure of a network from both a physical and logical viewpoint. It assesses the way devices communicate with each other internally. Conversely, a logical topology explains how data flows from one device to another based on network protocols. It involves assessing the physical layout of network cables and workstations. A computer network topology can consist of one physical topology and several logical topologies.Ī physical topology explains how computers, devices or nodes connect with each other in a network based on their location. It describes their physical arrangement and explains the logical flow of information throughout the network. Network topology refers to the way different computers, devices or nodes connect to each other in a communication network.

In this article, we explain what network topology is, list seven types of configurations and discuss the key features of network topology to help you choose the right setup for different circumstances. If you work as a network administrator or are pursuing a career in this field, then you might be interested in learning about different network topology types. They develop, implement and manage the layout or topology of each network to enhance its function. A network administrator is responsible for maintaining and improving the performance of an organization's computer network. Press firmly on both caps while turning them counterclockwise until they come off completely.Once both caps are off, lift out the magnet by pulling gently upward on it while simultaneously pushing it forward until it comes free from its housing inside your drill's chuck.Uses of a Magnetic Drill BitThe magnetic drill bit set can be used in various industries and applications, such as:Construction Industry: To bore holes in concrete, bricks, etc., for installing anchor bolts and anchors.Automotive Industry: To drill holes into engine blocks and cylinder heads for installing sensors, spark plug wires, etc.Removing Metal Shavings From Drilled HolesMetal shavings are common when drilling holes in materials like metal or steel. Place one finger on the bottom cap and another on top of the second cap (if your drill has two caps). Here are two methods for removing the magnetic drill bit:Slide the Magnet Out of Its Housing- Grip the top of your drill with one hand while holding onto the bottom of your drill with your other hand. However, a non-magnetic drill bit will work fine with wood or plastic.How To Remove The Magnetic Drill BitWhen you're done using the mag drill bit, remove it from your drill, so it doesn't get damaged during storage or transport. However, not all Mag drill bit materials are magnetic, so you may need to consider this when choosing a drill bit.When drilling holes in metal, it's essential to use a magnetic bit because it helps keep the drill bit from slipping off the workpiece and causing damage. Magnetic Drill Bits are available in different sizes, shapes, and configurations, making this product highly versatile and economical.Magnetic Drill bits are made of high-quality steel, which can be magnetic. Magnetic drill bits can be useful when drilling into steel as they reduce the need to clamp the workpiece and allow for higher speeds and fewer breaks.The Magnetic Drill Bit is also named as an Annular cutter bits. This type of drill bit has a magnetic element on the back side of the drill that attracts to the steel being drilled. Take a look at RS Components' extensive range of magnetic drill bits.What is Drill Bits Magnetic?A magnetic drill bit is a portable drill bit for drilling holes into steel or similar steel. When you want to drill or bore holes in steel, ceramic, or other rigid materials, you need drill bits designed with the right balance of strength and sharpness. Or you have to do a lot of drilling on steel but don't want the hassle and expense of setting up a magnetic drill press.All these problems and more are solved using a magnetic drill. Magnetic Drill Bits Are you tired of constantly moving your drill press around your workshop just so that you can perform drilling jobs? You may have a workshop with limited space, and moving your drill press is not feasible. The wrist blood pressure monitors on this list have a variety of features that range from simple, low-tech buttons to higher-tech app connectivity. We eliminated products from manufacturers who made “too good to be true” claims, or that had poor ratings on sites such as the Better Business Bureau. We looked for products that come from manufacturers with good overall reputations for customer service and reliability. So, we made sure to include only monitors that get more positive reviews than negative ones. In researching wrist blood pressure monitors, we found that many products have a lot of complaints and poor reviews. To pick the best wrist blood pressure monitors, we used these criteria: Customer reviews and complaint history While no at-home monitor eliminates the need to see a doctor regularly, the wrist blood pressure monitors on this list can be useful for supplying information for you and your doctor. When used correctly, wrist monitors can be accurate. Using a wrist blood pressure monitor is a viable alternative you can use both at home and in medical settings when an upper arm monitor is not practical. Upper arm blood pressure monitors may also be harder to use by yourself. However, this may not be practical for people who have upper arms that are more than 17 inches in circumference. The American Heart Association (AHA) recommends using an upper arm blood pressure monitor for testing. That’s where an at-home blood pressure monitor can come in handy. Whether you’ve received a diagnosis of high blood pressure (also called hypertension) or not, taking your blood pressure often and tracking the results can alert you to changes that might need medical attention. Why should you monitor your blood pressure? This is dates and mates with damona Hoffman. If you’ve read my advice in the LA Times, then you know, this ain’t your mama’s love advice.

You’ll never look at The Mickey Mouse Club the same way again. That’s the horror behind “The M Show Fan Club,” sometimes regarded as one of the best unsung stories of r/NoSleep. Imagine if your favorite TV show hid a terrible, dark secret. Turning childhood nostalgia into an unsolved nightmare, Reddit user lenalona writes in a more traditional narrative style as they take on the role of a woman remembering the scariest day of her adolescence. The back said “Welcome to The M Show Fan Club.” But right after her lecture she handed me a small square letter with my name printed on it. I remember there were tulips in our garden and my mom reprimanded me for plucking two to decorate the kitchen table. I sat next to her while working my way through Scarlett’s old girl magazines.” “It was early spring. Brandi still came over, but she was the only one watching. When Scarlett stopped watching I too began to skip the show. Brandi was still passionate about the show and watched it every day, but Scarlett lost interest. When the first snow began to fall we stopped checking the mailbox. “The M Show Fan Club” by lenalona “The letters were sent off and every day we all rushed to the mailbox to get our The M Show Club badges. While a good story on its own, it’s a heart-stopping comment from a user staying in character that adds the best plot twist to the story. Making great use of r/NoSleep’s format, Nathan goes the extra step in providing screenshots of his messages with “Emily” and photos where she’s “tagged” herself. Soon “Emily” begins feeding Nathan fragments of their old text messages, conversations never written down, and Emily alluding to being “FREEZING” and alone. But a year later, on September 2013, Nathan begins receiving strange Facebook messages from Emily’s account. In the story, Nathan’s girlfriend Emily died in August 2012. But look closely and you may believe that Nathan is slowly losing his mind. Probably the best example of what can be done in r/NoSleep, Nathan initially asks Reddit users for technical help. Some of them have removed me from their Facebook friends list.” The friends who noticed and said something thought it was a fucked up bug I found out recently that there have been friends who have noticed and didn’t say anything. I was too angry to sleep.” “She would tag herself in random photos every couple of weeks. I don’t know what to do.” by natesw “Around this period of time, I stopped being able to sleep. “My dead girlfriend keeps messaging me on Facebook. With Halloween upon us once again, here are just five of some of the best stories ever told on r/NoSleep:ĥ. Unlike the old tales of witches and devils, the monsters in these stories have evolved, becoming malevolent television shows or ghostly text messages from dead girlfriends that haunt living boyfriends. It’s like crowd-sourcing fear, and r/NoSleep is always in demand. Sometimes, users in the comments will break character, praising the “OP” (original poster) for the clever writing, but others add new layers to the terror. Unlike Creepypastas, another Reddit creation, the goal of r/NoSleep is a level of “role-playing,” where the author pretends the story is legit and writes pleading to their fellow Redditors for answers, help, or just a bit of hope. While the internet has always been a treasure trove for scary stories, r/NoSleep is unique. And they call come from everyday Reddit users. On Reddit, “the front page of the internet,” the massively popular (11,809,894 members) community r/NoSleep houses some of the creepiest, oftentimes longest short stories you could possibly find.

VoIP technology lets users make phone calls via business broadband internet connection. What’s the difference between SIP trunking and VoIP?īusinesses sometimes use the term “SIP trunking” interchangeably with “VoIP.” While the two are closely related, they are different, and investing in VoIP doesn’t necessarily mean investing in SIP. Switching from analog connections can also improve call quality.īusinesses can also use the computer hardware they’ve already invested in to make phone calls. The technology supports a business’s phone systems, bringing the cloud’s scalability, cost benefits and analytics features to its landline. In almost all cases, this network will be the internet. SIP trunking accomplishes this with Voice over Internet Protocol (VoIP), which digitizes a caller’s voice and transmits communications over an IP network. It can effectively connect that PBX to the cloud rather than directly to the PSTN. Using SIP trunks, a virtual version of analog trunks allows a SIP provider – typically called an “internet telephony service provider” – to take advantage of a business’s existing PBX hardware. A PBX system routes inbound and outbound calls and has advanced features like call blocking and call forwarding. In an analog system, physical trunk lines connect the business’s private branch exchange (PBX) to the public switched telephone network (PSTN).Ī PBX is a private telephone network that allows the phones in your office to connect with each other and outside callers. The technology behind SIP trunking makes it a good fit for businesses that want to reduce phone line costs and gain access to cloud-exclusive features. This capability provides the company with important data about how it uses telephone systems in day-to-day work. For example, a digital phone system is much easier to monitor with analytics tools that can track critical information about business phone calls, including frequency, length, audio quality and the number of missed calls. A SIP trunk allows a business to make local or long-distance calls over the internet without using traditional phone lines.īusinesses often adopt SIP trunking to reduce phone expenses or take advantage of cloud-exclusive features. What is SIP trunking?Ī Session Initiation Protocol (SIP) trunk is the digital version of an analog trunk line that lets users make outgoing and receive incoming calls. Here are the basics of SIP trunking, how the technology works, and strategies for finding a SIP trunking provider that offers the services your business needs. Managers can use the technology to leverage VoIP’s power to consolidate business communication systems, improve call quality and save money. SIP trunking allows any organization to upgrade its offline PBX to an internet-powered business phone system. |
