![]() ![]() Why does this happen and how does it work? The answer is the same for both questions here. That is, the number of rows in the resulting matrix equals the number of rows of the first matrix $A$ and the number of columns of the second matrix $B$. The result of the multiplication $A*B$ (which is different from $B*A$!) is a $n \times w$ matrix, which we call $M$. Also assume that $B$ is a $m \times w$ matrix. Assume that $A$ is a $n \times m$ matrix, which means that it has $n$ rows and $m$ columns. Let's say we have two matrices, $A$ and $B$. Matrix-Matrix Multiplicationīefore starting, it is helpful to briefly recap how a matrix-matrix multiplication is computed. Also, if you have any doubt, feel free to ask me for help in the comment section.

![]() Instead, it stays on the surface, from where it’s easily transferred to your skin. Beauty blenders are made from a special material that, when damp, won’t absorb much of your makeup. Two things separate beauty blenders from their predecessors - their shape, yes, but also that you’re supposed to soak them in water. Your foundation would soak into the sponge, wasting more of it than ever ended up on your skin. The rigid lines and points were still less-than-perfect for distributing the product evenly, however.įor decades, this and the round disc were our only options – I remember my mother having so many of these little wedges scattered over her vanity! They were cheap, and they got the job done. That’s why most of us graduated to those triangular sponges you’d also find at the drugstore. There are even liquid compacts using this type of disc sponge nowadays.īut their uses are limited, mainly because the shape is not ideal for precision application. They are pretty easy to use – simply swipe your pressed powder first and then dab it onto your skin until you achieve sufficient coverage. Believe it or not, those are still around. We all remember those round disc sponges that you’d get in your pressed compact from your favorite drugstore brand as a teenager. We’ll explain how to choose the best beauty blender in a moment, but first let’s talk about why they’re all better than a basic sponge. In short, each beauty blender design allows you to create a different, specific finish. The different curves and points are suited for different parts of your face, and even the color can play a role depending on the intended application. What makes a beauty blender so special? Well, the difference between a beauty blender and a standard makeup sponge is primarily the shape. And soon they were disappearing into the pockets and makeup bags of everyone she worked with! Recognizing the retail potential, in 2003 Rea Ann launched her famous beauty blender that has spawned countless imitations and transformed the way women around the world apply their makeup.īeauty blenders vs. Unable to find anything that created a quick yet flawless finish, she began hand-cutting sponges into the now-famous egg shape. Dre, but it was being hired as the head makeup artist for the first-ever high-definition TV show that led to her lightbulb moment. ![]() Rea Ann has perfected the complexions of high-profile celebrities from Tupac to Dr. If you make a relatively small amount of makeup, it is recommended to replace it every 2 months.Originally the brainchild of makeup artist Rea Ann Silva, the Beautyblender is a tool that, quite frankly, revolutionized the beauty industry. If you make up more frequently, it is recommended to replace it with a new makeup egg once a month. The sponges cannot be used for a long time. ![]() The latex free makeup sponges is very dense, it feels very soft and smooth, there is no roughness and friction at all, and it will not cause damage to the skin. Do not use the make-up sponges for a long time without cleaning, otherwise the blender sponges are prone to breed bacteria and may cause acne after contact with the skin. Make-up eggs should be cleaned once a week. If you accidentally spray too much lotion, you can use a clean paper towel to squeeze out the excess water. After being pressed, the lovely songes can automatically bounce back in just 1 second, and the application is very Convenience.īefore using the cosmetic sponges, you should soak it with water and use it when it is half dry and not wet. Its special feature is that the texture is soft and the shape recovers very quickly. It is a sponge material, not as hard as other makeup tools. The shape of the sponge is like an egg, so sometimes people named it beauty egg sponges. It is best to use the sponges in a semi-damp state, so that the makeup effect will be better. The egg shaped application sponge can be used not only to apply the liquid foundation, but also to paint blush. ![]() It can make the liquid foundation more docile. The latex free blender sponge is a tool for applying makeup. ![]() ![]() Besides, each image can be sent to the default system viewer or you can use the integrated Quick Look plug-in. In Group List view, the browsing process is more streamlined and you get to review more images in a shorter period of time. In Face-to-Face mode, besides large thumbnails, you get to see the matching percent, the location on drive for each image and how many similar photos have been found. The processing time is, of course, determined by the source library’s size and, once it is over, you will automatically enter the Review area where you can analyze the results Face-to-Face (two at a time) or in the Group List view. On the other hand, the Duplicates detection algorithm analyzes the actual image and not the metadata: the comparison is done byte-by-byte, by image or by thumbnail. When the time factor is involved, you get to group images by taking into account the maximum time interval that passed between taking two pictures. The next step is to set the comparison criteria (Bitmap, Histogram, Time Interval, Time + Bitmap, Time + Histogram and Duplicates only) and make the necessary adjustments for each case.įor the Bitmap and Histogram modes you can specify the bitmap size, color mode (RGB or Grayscale), preprocessing (none or blur), color sensitivity (high, average or low) and matching level. ![]() Located on the right side of the main window, the File Settings panel can be used to filter the gallery by choosing the file types you want to work with, the minimum size and the sorting method (by name, by title or none, ascending or descending). You must use the Media Browser to add images from those libraries in order to have them synchronized with PhotoSweeper. The images included in the iPhoto, Aperture or Lightroom libraries will be marked accordingly. Naturally, you can adjust the thumbnail size, but you will also view the location of each file on your drive, the complete name, creation date, resolution and size. Here you must add the photos you want to process, and thumbnails are automatically generated. PhotoSweeper will initially display the Setup panel. PhotoSweeper is quite powerful when it comes to processing: granted, the images had small sizes, but the app was able to show the results for over 1000 files in a matter of seconds. The good news is that the marked images remain in the Box. The Box area is available at any time from any location, but the results browser deals with only one analysis at a time: if you go back to the Source area, you must start over. Each space takes its turn in the main window and the switch is smooth and streamlined. PhotoSweeper’s workflow is based on three areas: the Setup or Source, the Review board and the Box. PhotoSweeper integrates beautifully in the system: gray background for the entire application, a wood panel for the working area, rounded edges, full screen support, help messages on hover for each button, a short “PhotoSweeper Tips” tutorial that presents the most important features and an extended user guide. PhotoSweeper comes with the tools to make that happen: powerful and efficient sorting algorithms that will help you review and manage those types of pictures. The overall size and disarray can be reduced by taking care of two recurring issues: duplicate files and similar photos. ![]() Normally, you just find yourself drowning in long galleries of pictures that you don’t even remember taking. Regular image libraries usually contain a considerable amount of data that is time consuming to process from the start. PhotoSweeper will help you locate and manage those unnecessary files. Sooner or later, your drive becomes cluttered with duplicate or similar pictures that make it harder for you to find exactly what you need. Large photo libraries tend to become a mess even if you do your best to keep them organized. ![]() ![]() ![]() ![]() All the configs Apple seems to offer are more graphics power: force more dGPU and therefore force worse battery life. Only using hacks – like gfxCardStatus – it is possible to get into the state of forcing more iGPU and better battery life (compared to – sometimes badly working – "Automatic Switching"). ![]() So, in effect, yes, "Higher Performance" is the same as unchecking the checkbox in the first screen, that is, to force the dGPU. checked "Higher Performance" = defaults to dGPU not switchable to iGPU.Unchecked "Automatic Switching" = defaults to dGPU not switchable to iGPUĬhecked "Better Battery Life" = defaults to iGPU not switchable to dGPU checked "Automatic Switching" = defaults to iGPU switchable to dGPU.Influencing these settings leads to the following options: just a simple Java stub with demanding graphics or a badly written app). Depending on the version of the operating system or the application this request could be quite arbitrary (e.g. IGPU is used as default but anything requesting "real graphics power" leads to switching to the dGPU. The default checkbox you see without gfxCardStatus means: Once the GUI arrives the drivers for both iGPU and dGPU are available, full acceleration for both is available and the power management kicks in.įor graphics performance and power management Apple deems fit a rather simplistic scheme: On a Mac with dual switchable graphics (iGPU and dGPU) the general setup is as follows:īoot uses usually dGPU with limited, basic capabilities since the drivers aren't loaded yet. ![]() ![]() ![]() In the background, a faint but noticeable medium low sound that regularly builds up and then drops off before beginning again: industrial hum, occasional noise of gas in machinery.Ĭontinual low pitch rush of steam with drips.Ĭontinual sound of machinery operating interspersed with louder machine noises.Ĭontinual sound of machinery operating interspersed with gas venting noises.Ĭontinual industrial rumble interspersed with rattles & squeaks.

And so we could look at the thirty-second of the thirty-three occupied orbitals, the next to the highest occupied orbital, and it looks like that. There’s the framework of the molecule superimposed on this map, and that triangle on top there, on the right, is what we’re looking at. Now, can we understand that, from the point of view of molecular orbitals, of Schrödinger’s equation why it should look like that in this particular case? So would a computer’s molecular orbitals provide understanding? So I was just showing you, as the class assembled, how you get these molecular orbitals, and I was showing you some of them. They don’t lie on the line between the nuclei. So that bond isn’t there in the electron density, the difference density. Professor Michael McBride: And one bond is missing. Student: And there’s another bond that’s missing. Professor Michael McBride: Some of the bonds are bent, and what else? And you remember what’s funny about it? What’s pathological? Dana? We looked at a cross-section through those three atoms, and it looked like that in the electron difference density. Right? When we were looking, we looked at this molecule and said that the bonding, from the Lewis point of view, was pathological. Okay, so let’s see if we can understand some of the things that we didn’t understand when we were looking at the molecule really, with X-ray diffraction. You’re a chemist, and your goal is to understand things let the computer do the heavy lifting mathematically and you understand it. But you’re neither the molecule - well you are a molecule - but you’re neither the kind of molecule we’re studying, nor are you a computer. ![]() You can’t do it absolutely, but you can, depending on how much computer power you want to throw at it, you can do it close enough for most purposes. Right? And the goal of the computer is to approximate the Schrödinger equation. ![]() Or we can do a computer calculation, and if we do a careful enough computer calculation, we can get something that we believe is pretty close to reality, like the total electron density I showed you. We can look at the real molecule, for example, with X-ray. Professor Michael McBride: Okay, so now we have a number of different perspectives we can take on understanding what holds molecules together that is, on bonding.

These are police tactics used to get a person to voluntarily waive their rights. They may say that if a person won’t tell them what happened, the authorities only have another person’s version of events. In these situations, police officers may also tell a person that they simply want to hear their side of the story. When someone gives voluntary statements to the authorities, or goes to the police station because the police officers asked them to, the police do not need to inform the person of their rights beforehand and can use those statements as evidence. At this point, police officers must inform the person that he or she has the right to remain silent and their answers to police questioning can be used as evidence against them. The situation is different when a person is placed in custody, meaning, they are unable to end the interaction with the police. Police officers go to great lengths to try to get people to voluntarily answer questions so they don’t need to be informed about their rights. They don’t need to inform you that you are not required to answer their questions or that your answers can be used as evidence against you. If you go to the police station and answers their questions, the interaction is considered voluntary.ĭue to the fact that you’re not placed in custody, meaning you haven’t been arrested or coerced into answering questions, the police officers don’t need to read you a Miranda warning. ![]() They won’t specifically tell you that you have to answer their questions, but they may subtly suggest that coming in will be helpful. For example, a police officer calls you and asks you to come to the police station to answer a couple of questions. The police can engage in communications with private citizens, in a non-coercive manner, and ask them to voluntarily come to a police station to answer questions. When law enforcement officers conduct an investigation they do not need to inform a person about their right to refuse to answer questions as long as the person being questioned is not in police custody. To learn more call and schedule a consultation with a DC criminal lawyer today. The following is more on when Miranda rights come into play and whether statements you voluntarily give to police can be used against you. Despite what you see in television and the movies, law enforcement is not required to read you your Miranda rights everytime you are contacted. ![]() ![]() NSF/Dishounoured Payment Fee: $25 - Charged if a payment you make is dishonoured.Ĭharges for Copies: $2 - Charged when you request a copy of a statement.Ĭredit Balance Fee: The lesser of $2 or the amount of your credit balance - Charged on the last day of a billing period when there is a credit balance on the account and the account has been inactive (other than any credit balance fees) for the previous 2 billing periods. ^ Information for the Triangle™ Mastercard® and Triangle™ World Elite Mastercard®:Īnnual Interest Rate(s): All charges to your account (excluding cash transactions and related fees) - 19.99%Ĭash transactions (for example: cash advances, balance transfers, convenience cheques, money transfers, purchase of travellers cheques and gambling transactions) and related fees - 21.99% (if you reside in Quebec) or 22.99% (if you reside outside Quebec).įor the Triangle Mastercard only: If you are not approved for a card at the above rates, Canadian Tire Bank may still issue you a card at the following annual interest rates: (i) if you are a resident of Quebec, 21.99% for all charges or (ii) if you reside outside of Quebec, 25.99% for all charges (excluding cash transactions and related fees) and 27.99% for cash transactions and related fees.įoreign Exchange Conversion: All transactions made in a foreign currency will be converted to Canadian currency at the then current Mastercard conversion rate plus 2.5% (for charges to your account) or minus 2.5% (for credits to your account) when the transaction is posted to your account.Ĭash Advance Fee: $4 - Charged when the transaction is posted to your account.
