It also comes with a free built-in photo editor you can use to make final touches. It is designed to be user-friendly and powerful enough to convert batches of images. Converted files will be ready within a couple of seconds. Pixelied is the best SVG image converter online that can take any image file and convert them to SVG without any downgrade in quality. How to Convert?Ĭlick on “Upload files”, select the JPG files you want to convert (or just drop them to the window outlined by a dotted line) and wait. and for website development as well, because all SVG files are just code, the file size is minimal, which allows you to optimize the website and its visual part. Also, it is great for working with graphics: icons, logos etc. It is convenient to use SVG for schemes, charts and similar graphic documents. There are a lot of ways to use it in everyday life, but you should keep in mind that this format is best suited for images with simple shapes and clear borders, without any small details. SVG (“ Scalable Vector Graphics”) is based on vectors, not pixels, which is its main advantage - when being scaled, images in the SVG format do not lose quality. The SVG format does an excellent job with everything that the JPG format cannot do. There is nothing better than JPG for photos yet. However, JPG is still widely used, as it is easy to work with and it is supported by most devices and software. Also, JPG files lose quality with numerous editing and their size directly depends on the resolution of the image. What is SVG SVG stands for Scalable Vector Graphics SVG is used to define. JPG files, as other bitmaps, consist of pixels, so this format is not suitable for images where loss of quality is unacceptable when scaling. If you want to study these subjects first, find the tutorials on our Home page. JPG (“ Joint Photographic Experts Group”) is a graphic format mainly used for storing photos and pictures. If you place two pictures side by side, they will seem identical. JPG and SVG - both formats refer to images.

Where PASSWORD is a strong and unique password. Once at the MySQL console, create the new user and add GRANT OPTION, which gives the user the ability to grant privileges to other users, with the command:ĬREATE USER IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION.First, access the MySQL console from the server hosting MySQL with the command:.Yes, there is already a root user, but that user is bound to localhost connections only. Sudo nano /etc/mysql//mysqld.cnfĪt this point, MySQL is open for remote connections, but you’ve yet to create a user for access. Log into your MySQL database server and open the configuration file with the command:. The first thing we must do is configure MySQL for remote connections. You’ll also need a user on the MySQL server with sudo privileges. To make this connection, you’ll need a running instance of MySQL and either a Linux machine to test the connection or any number of MySQL clients that allow for remote connection setup. With that said, let’s get this configuration up and running. Understand, this can be considered a security issue for some instances, so you want to make absolutely certain that not only is your LAN secure but you’re using very strong passwords for the MySQL users (which you should be doing anyway). I’m going to walk you through the process of configuring MySQL 8 to connect to it remotely as a user with access to all databases. SEE: Take advantage of TechRepublic Premium’s back-end developer hiring kit. This can be a bit tricky to pull off, but it’s not impossible. Recently, I was tasked to add a MySQL database GUI for a client and came up against an issue where the database server wasn’t properly configured to accept remote connections. Jack Wallen shows you how to make this possible. How to Create a MySQL 8 Database User With Remote AccessĪt some point, you're going to need to connect to a MySQL 8 database remotely to manage your databases. It is the coolant hose that transports the hot liquid to the radiator so the coolant can cool. If it is around the same price to replace your broken water pump with a new water pump, then that is the better option. You may end up paying over $550 to repair a water pump. In some cases, it is better to replace the water pump completely.Ī typical water pump costs between $200 and $350. The cost to repair a broken water pump depends on the type of water pump and how much damage it has experienced. That is the sound of the pump trying to push the coolant into the system, but the bearings are worn out. One obvious sign that will tell you if the issue is the water pump hearing aid is an extremely high-pitched whining noise coming from your engine. The heat from the engine will stay trapped in the coolant and it cannot capture any more heat from the engine. This means that not only will the coolant stay in hot areas of the engine for a longer time, but it will also capture so much heat that cannot cool to a cool temperature after it passes through the radiator. If it corrodes, then the liquid coolant will creep through the coolant system. The water pump moves the coolant through the coolant hoses and system. This includes the parts required to fix the radiator and the labor of the mechanic. The cost to fix a coolant leak from a radiator is about 500 to $700. Heat should escape from the radiator, but the coolant should not leak out. It can also be that the radiator is leaking coolant. The color change may result from rust on the inside of the coolant system. But when the coolant hose clubs, it can change to a murky brown color. The color of healthy fresh coolant is usually bright green or bright blue or a mix of green and blue. You will know if the issue has to do with the radiator when the color of the coolant changes. The coolant goes through the radiator and the radiator releases the heat from the coolant so the coolant can cool back down. The purpose of the radiator in the coolant system is to help remove heat from the engine. Those reasons are a clogged coolant hose, a faulty water pump, or issues with the radiator. So what causes coolant to heat too far or to go over temperature? There are three main reasons a coolant can heat to a temperature that is far too high. If the coolant cannot lower the temperature of the engine, do not be surprised when the engine overheats. However, if issues arise with the coolant system, it is possible that the coolant cannot lower the temperature of the engine. We rely on the coolant system in our vehicles to protect the engine and keep it at an optimal temperature. 3 Conclusion What Does it Mean When the Coolant is Over Temperature? 12/3/2023 0 Comments Types of wire strippersSelect the appropriate notch on the wire stripper that matches the size of the wire.Here’s a simple step-by-step process using a manual wire stripper: To strip wire fast and with ease, you can use a wire stripper. Wire stripping machines use various methods, such as blades or mechanical rollers, to cut and remove the insulation from the wire. These machines are commonly used in industrial settings, recycling facilities, and other situations where there’s a need to process a significant amount of wire quickly. Wire stripping machines do work and can be quite efficient for stripping large volumes of wire. Use your fingers to peel it off the wire carefully.Next, you need to rotate the wire and repeat the incision until a portion of the insulation is sliced.With patience, make a shallow incision along the length of the wire insulation.Hold your wire firmly with one hand and grab your blade with the other.Once you’re ready, run through these steps: To strip wire by hand without a wire stripper, you can use a utility knife or a sharp blade. Manual wire strippers require manual adjustment for different wire sizes, automatic strippers adjust automatically to the wire diameter, and self-adjusting wire strippers can handle various wire sizes without the need for manual adjustments. There are several types of wire strippers available, including manual wire strippers, automatic wire strippers, and self-adjusting wire strippers. What types of wire strippers are available? After making the cut, the user can easily remove the insulation from the wire. Wire strippers work by clamping onto the wire and then cutting or scoring the insulation without damaging the conductive wire inside. Controlled by a spring mechanism, the ergonomic handles reduce fatigue. The tool can also crimp insulated and uninsulated terminals of different sizes. The Umi Automatic Wire Stripper offers adjustable stripping thickness and length through a set screw and wire stop. The tool is perfect for stripping various wires, including PVC, single, multiple and fine-stranded conductors. Its high-quality steel, zinc alloy jaws and scratch-resistant rubber handle ensure durability and longevity. This three-in-one multifunctional wire tool is designed for cutting, crimping and stripping.

If you don’t have the time to read our full article, we’ve rounded up 5 great wire strippers below: Product name What types of wire strippers are available?.The end piece is spring-loaded, which is slow and tiring for the thumb when done repetitively.īy fixing the end piece of the wire stripper in an adjacent vise, the full hand can be used to pull the end piece open, taking advantage of much larger muscle groups. The example above shows a hand wire stripper that requires pushing the end piece open with the thumb to place the wire. Note the swivel ball joint on the vise, which enabled orienting the wire slots for good visibility.Īfter: Place end in vise, pull open with full hand The device was efficient and easy to use. The author created a low-cost lever device in a special situation, using a vacuum-based vise and a short length of PVC pipe. Multiple types and brands are available on the market. Options for improvementįor high volume production, powered wire strippers offer many advantages. Newer designs of wire stripping tools can be ingenious and better than simpler tools, but still can be stressful depending upon frequency and the type of wire. When used repetitively, wire strippers can place significant strain on the hands. 12/3/2023 0 Comments Opto isolator simulationThe linearity degrades at higher operating currents due to reduction in the CTR of the opto but looks good if the maximum current is kept to no more than a couple mA or so (1.6mA maximum in this simulation). The simulation results are somewhat idealized of course, as determined by the accuracy of the models, and the real linearity will depend upon the actual characteristics of the opto coupler used, but should still be good, adequate for non-critical voice and music applications. (Note the blue trace where the output is graphically superimposed over the input so any non-linearities are more readily observed). If a symmetrical output signal with respect to ground is required, then the output can be capacitively coupled to a load resistor connected to Ocom.Īs can be seen, the output voltage plot appears quite linear with respect to the input. R2 can be increased in value to increase the output voltage in this configuration, the tradeoff being some increase in the distortion. If you have a high impedance load (>1.5KΩ) and are satisfied with an output voltage of about 1/2 the input (depending upon the opto transfer gain), then U5 may not be needed and you can use the voltage across R2 as the output. Op amp U5 is a buffer/non-inverting amplifier that amplifies the voltage across R2 to convert the opto isolator output current back to a voltage. The opto is operated Class A with about 1 mA DC bias current. Op amp U3 is configured as a current driver for the opto input, generating a current proportional to the voltage input. (Ocom is the isolated output common and Rsim is just to allow the simulation to run with an isolated output ground). This eliminates the non-linear LED input voltage to current relationship, with the opto isolator output current typically being quite linear with respect to the input current, especially for low current levels.īelow is the LTspice simulation of such a circuit using the 4N25, a common and representative general purpose opto isolator. Sorry for the long story, I am still learning.There are special purpose (and relatively expensive) optical isolators available with separate feedback connections designed for high analog linearity and fidelity but, for non-critical AC applications, a standard opto isolator may be adequate if it is driven by a current source instead of a voltage. Hence I started searching for it and found one i.e SFH628A-3, however I am not good in understanding their datasheet and need help to see if it fits. Due to all these factors, someone suggested me to find another opto which works at very low current. I am also not able to use a x-capacitor or use a transformer due to size constraints. Now I could reduce the resistance, however the heat dissipated would be more (which I don't want). I calculated the voltage and found that for 145V AC and a series resistance of 440K, the current is just 0.33mA which may to be insufficient to turn on the opto. While testing my circuit at various input voltages I found that the opto will start giving fluctuating output when my voltage is 145V. I had connected a series resistance of 440K (1/4W) and everything seems to be fine i.e the microcontroller is able to sense when there is line and otherwise. The optocouplers I have evaluated are PC814, H11AA1 and SFH620A-3, out of which I found SFH620A-3 to be more efficient (must be due to the better CTR). I am trying to detect line voltage (230V AC, if the supply is ON/OFF) by a microcontroller with the help of an AC optocoupler. 12/3/2023 0 Comments Apple magsafe chargerIt’s the kind of small, practical, detail that comes from thinking outside of the box. It’s also a unique Apple feature, something practical that Apple fans can crow about safe in the knowledge that rival laptops are missing this one vital feature. This means that if you pull it in any direction other than straight out it disconnects, and there’s virtually no force required to remove the connector. The true genius of MagSafe is that it works by “non-axial” force. MagSafe protects the laptop because the cable instantly unclasps, leaving the laptop on the desk and the cable flapping harmlessly on the floor. Tripping over the adaptor cable drags the laptop off of the desk and it falls on to the ground (and is potentially damaged). When a laptop is sitting on a desk or table, and plugged in to a socket near the ground, the wire between the two is a trip hazard. The advantage to using MagSafe is safety. “The surface area of two magnetically attracted halves determines the number of magnetic flux lines and therefore the holding force between them because the holding force is proportional to the contact area between the two magnetically attracted halves.” These cases will allow the iPhone to securely snap on to the MagSafe magnets, and allow MagSafe snap-on charging right through them. Some silicon cases are already available, others will launch later. The leather wallet is shielded so your credit cards should be protected from the magnets inside the iPhone and the case.Īpple will also sell leather cases, but these do not yet have a price or release date.Īpple sells a number of silicone and clear cases It comes in four colours and attaches to the back of the iPhone (so it provides somewhere for your cards, rather than a protective case).

We don’t readily see any options for adding checkmarks in Excel. However, how can you add check marks to your checklist or any other file in Excel? Not to forget, you can readily edit it for any changes whenever you want to. Making a checklist in Excel is way more convenient than any other hand-written checklist for you can access an Excel checklist anytime, anywhere. The utility of checklists comes from the check marks that you can put against different items in them.Īlthough we have outgrown the times of preparing checklists in a hard form, they continue to be a substantial part of our busy schedule management.

If you want to convert strings to other Java primitive fields, for example, a long, use methods like Long.parseLong(), and so on.If you're interested in converting a String to an Integer object, use the valueOf() method of the Integer class instead of the parseInt() method.Integer.toString(int i) is used to convert in the other direction, from an int to a Java String.While I’m in this neighborhood, here are a few related notes about the String and Integer classes: In this example, I don’t really need to use the String class trim() method, but in a real-world program you should use it, so that's why I’ve shown it here. If the conversion attempt fails - for instance, if you try to convert the Java String fred to an int - the Integer parseInt method will throw a NumberFormatException, which you should handle in a try/catch block.

Although this extra pressure may be enough to tamponade further venous bleeding without significantly increasing a subject’s discomfort, the high levels of pack pressure required, make this unlikely to be of significant use in the clinical setting. It is possible to increase the ipsilateral nasal cavity pressure by inserting a contralateral nasal pack. This effect was only statistically significant at intra-nasal pressures of 140 mmHg and above (Wilcoxon Signed-Rank test, p < 0.02). At higher pressures, the subjects reported lower mean pain scores when bilateral packs were used compared to unilateral. This change in ipsilateral intra-nasal pressure is greater at higher total inflation pressures. Higher ipsilateral intra-nasal pressures are achieved when additional contralateral nasal packs are inflated. This procedure was repeated at incremental pressures. The subject’s level of discomfort was scored on a visual analogue scale. The contralateral pack was inflated to match, and any intra-nasal pressure change on the first side was measured. The first pack was inflated to a pre-determined pressure. Rapid Rhino ® 5.5 cm anterior packs were inserted bilaterally following topical nasal preparation with co-phenylcaine. 15 volunteers were recruited according to strict criteria. There is little evidence to suggest that bilateral nasal packing increases intra-nasal pressures compared to a single pack (or is well tolerated) for uncontrolled unilateral epistaxis, but it is often performed and justified on those grounds. |
