Here Are The Odds Of Hitting A Deer In NJ: How To Avoid It This Season - Patch

ragamnyakabar.blogspot.com

NEW JERSEY — Deer — including especially frisky bucks competing for mates in what’s called “rut” — are making New Jersey’s rural roads, and some more isolated stretches of urban highway, more dangerous at this time of year.

State Farm, the largest auto insurer in the country, said industrywide casualty claims data puts the odds of hitting a deer or other animal at 1 in 213 in the Garden State.

November, October and December, in that order, are the most dangerous time of year for animal collisions. Deer are involved in the largest majority of claims, State Farm said, followed by collisions with rodents, dogs, raccoons and coyotes. Claims for rodent damage includes chewed wiring and other destruction.

The greatest odds of hitting an animal on the highway are in West Virginia, Montana, Pennsylvania, Michigan, Wisconsin, Iowa, Mississippi, South Dakota, Virginia and Missouri, the insurer said. The odds range from 1 in 38 in West Virginia to 1 in 80 in Missouri.

Nationwide, the odds of hitting an animal are 1 in 127.

To put that in perspective, the odds of finding out your child is a genius are about twice that, at 1 in 250, and the chances of catching a ball at a Major League Baseball game are more than quadruple that, at 1 in 563, State Farm actuaries have said.

State Farm’s analysis was based on claims filed across the industry for the year ended June 30, 2023. The highest number of claims filed was in Pennsylvania, with an estimated 153,397. Michigan was second with 133,636, followed by Texas (96,000), North Carolina (88,770) and Ohio (82,395).

The majority of collisions occur around dusk on roads that don’t have a lot of traffic. State Farm said a survey of its members showed between 30 percent and 50 percent of drivers had collisions with animals under those conditions.

Additionally, one risky driving habit, whether speeding or using a cellphone, increases the chance of an animal collision by 23 percent, State Farm said.

Here are some tips to avoid a collision:

  • Slow down, especially if you see an animal close to the road;
  • Stay alert and scan the road for animals at any time of the day or night;
  • Pay attention to “deer crossing” and other animal signs;
  • Reduce distractions, including putting your cellphone out of sight;
  • Brake as necessary to avoid hitting the animal, reduce your speed, honk your horn and tap your brakes to warn other drivers;
  • Don’t swerve — if a crash with an animal is inevitable, maintain control of your vehicle and don't veer off the road; Use high beams and note, too, that flicking your high beams on wildlife may cause the animal to scurry away;
  • Be on alert during peak season for animal crashes, especially around dusk and dawn;
  • Remember that deer travel in herds and if you see one, there are probably more nearby.

3D Printer Layer Shifting: How to Avoid it - Tom's Hardware

ragamnyakabar.blogspot.com
3D printer layer shifting
(Image credit: Printables)

Layer shifting is an issue where the layers of the 3D-printed object misalign or shift during the 3D printing process resulting in noticeable defects in your design. You may notice the upper layers are not correctly positioned on top of the lower ones, and the entire print might be tilted. In severe cases, you can even see cracks or splitting of the layers, especially when the print head collides with previous layers. 

Several factors contribute to this issue, including mechanical issues within the printer, like loose screws and belts, to software problems like using a higher speed and acceleration settings in the slicer. Even if you are using one of the best 3D printers, if you don’t correctly set the various components of your 3D printer and slicer settings, it will cause issues during printing. But thankfully, fixing this issue isn’t hard, as we have explained below. 

Properly Tighten the Screws and Belts

(Image credit: Tom's Hardware)

Screws hold all the components of your 3D printer in place, and the belts control the movement of the print head along the X and Y-axis. When the stepper motor turns, it drives the belt, and this causes the print head to move across the build platform horizontally. 

It’s important to always check all the screws in your 3D printer and the belts to ensure you tighten them well because when loose, it will cause inaccurate movements and vibrations as the printer moves resulting in layer shifting. As you do so, be careful not to overtighten, especially the belts, as they will strain the motors and bearings.

(Image credit: Tom's Hardware)

In addition to properly tightening the screws and belts, you should also consider lubricating the extruder gears, bearings, rails, and other moving parts to ensure they operate smoothly with minimal friction preventing any uneven motion that might affect your print quality. As you do so, be careful not to overdo it, as it can attract dirt and debris, which can cause other issues. 

You should also consider using a firm table that is sturdy and doesn’t wiggle during 3D printing. If your 3D printer has no rubber feet, you should consider adding them. For example, you can use glue to attach them to the corners of the base to absorb the vibrations. This can also help fix a noisy 3D printer. If you still face shifting because of vibrations, you can buy four clamps and use them to hold the sides of the printer to your table.

Calibrate Your 3D Printer Correctly.

(Image credit: Tom's Hardware)

When troubleshooting any 3D printing issue, the first thing most of us check is if the printer is calibrated correctly. That same applies to layer shifting. You need to check if all the components of your machine are set correctly to avoid issues. The first thing you need to consider is to level the 3D printer bed properly. An uneven or misaligned print bed will make the design not adhere properly to the bed, and you need to ensure that you do it right. 

You can manually level the 3D printer bed or use the automatic feature if your 3D printer supports it. After leveling your 3D printer bed, the next thing you need to calibrate is the E-steps. You have to ensure that it deposits the right amount of filament during the printing process. If the nozzle extrudes less filament than required, the print will have gaps, or the layers might be weak and easier to shift. The filament that you are using should also be the one ideal for your nozzle to avoid jamming or clogging that can bring other issues that can lead to shifting of layers. You should ensure that you use the best 3D printer filaments as they have uniform diameter and are free of impurities.

Also, you need to check your 3D printer axis and calibrate it properly. You can print a small cube, measure each dimension, and use the values to fine-tune your axis. You also need to replace your 3D printer nozzle if it’s damaged, or you can simply clean it properly to avoid any debris from preventing the filament from extruding correctly.

Use Proper Speed and Temperature

(Image credit: Tom's Hardware)

If you print at a higher speed, it can result in excessive stress on the moving parts of your 3D printer resulting in vibrations and even making the screws and bolts loose. You also maintain a consistent speed as sudden changes, especially in sharp corners, can cause the layers to shift. Also, high speed can cause the pulleys to skip some teeth, resulting in layer problems and so you should keep a speed of about 50-60 mm/s. 

Also, you should keep the travel speed to around 100 mm/s. Anything above that can bring issues. You can find travel speed settings in the Travel section of your slicer. If you have enabled combing, you should check the Avoid Printed Parts When Traveling.

(Image credit: Tom's Hardware)

In the speed settings, there are also Print Acceleration and jerk settings and in Cura you can find that the default value for acceleration is usually around 1000 mm/s.

(Image credit: Tom's Hardware)

The default value of jerk settings, on the other hand, is around 8 mm/s.

(Image credit: Tom's Hardware)

Both of these settings control how the print head moves and changes direction. If you use values higher than the default, it can result in layer shifting as it can result in vibrations and increased movements of the print head.

In addition to speed, ensure that temperature is consistent. If the bed temperature is not constant or set too low, for example, the first layer may not bond correctly to the surface and it will cause some sections to detach, which leads to misalignment of the subsequent layers, especially due to warping and curling of the base layers.

Enable Z Hop Feature

(Image credit: Tom's Hardware)

Z hop is a feature that instructs the printer to slightly lift the print head in the Z-axis as the printer moves between different sections of the print or when it moves to a new location. This vertical movement ensures that the print head doesn’t collide with any of the previous printed layers and this also prevents layer shifting. This feature is helpful, particularly when printing designs with tall or thin structures. You can enable this feature in any of the best 3D printer slicers.

The above methods should help you fix the layer-shifting problem. If it doesn’t, you should also check on your wires and the cooling fans and ensure they all work as expected. After adjusting your settings and checking the hardware, I recommend printing a layer shift torture text design before you start printing your design to see if everything is working as expected.

What Is Noise in Photography? 5 Ways to Avoid It - MUO - MakeUseOf

ragamnyakabar.blogspot.com

Key Takeaways

  • Noise is an inherent aspect of photography that can reduce clarity, but it can be minimized through proper technique and understanding.
  • Noise in photography comes from various sources, but the key is to focus on the signal-to-noise ratio, ensuring that the signal (desired image) is stronger than the noise.
  • Techniques to reduce noise include correctly exposing the image, using a lower ISO, utilizing HDR merging, applying noise reduction in moderation, and using a camera with a larger sensor.

Some embrace noise, some want to get rid of it. No matter what side you’re on, it’s a fact that noise is an effect that reduces the clarity of photos. Almost every camera has the capacity to take minimal-noise photos, and it’s all down to understanding and technique, which you will learn here.

​What Is Noise in Photography?

Noise in photography is an ambient, unintentional signal the camera sensor receives. This ambient signal is present in all cameras and is even present in our eyes. Not to be confused with grain, which comes from film; noise is usually most visible when using high ISO settings and brightening dark images.

While you can’t get rid of it completely, you can figure out how to minimize it with proper technique and knowledge.

​What Causes Noise in Photography?

Noise is always present; it's just a matter of whether it’s visible or not. There are many sources of noise as well. Some noise can come from the sensor, some from electrical noise, and some from the quantum nature of photons. However, the best way to address noise is to understand the signal-to-noise ratio.

Signal-to-Noise Ratio

Don’t concern yourself with the type of noise, but more with the ratio between the signal (which is the image you want to take) and the noise.

Think of the image signal equally to an audio signal. Visualize it with this signal level bar, the minimum signal would be the noise that you have no control over. The red bars represent the noise, and the green bars represent the signal.

Signal to noise ratio graph

The first pair on the left has low noise and a high signal, the second has a low signal while having the same amount of noise, and the last pair has the signal raised up to make it stronger. As you can see in the last pair, having a low ratio means that you’ll end up raising the noise much more than the properly exposed image.

Here’s another example of signal-to-noise ratio in an actual image. These are zoomed in to make it easier to see the noise.

Exposure boosting noise comparison

The first image on top is properly exposed, even being overexposed on the bright spots, and the second is underexposed. The image below is a side-by-side of the underexposed image brightened up to match the exposure of the first image. As you can see, there’s a ton of noise as the noise levels go up with the signal by a large amount compared to the properly exposed image.

​How to Avoid Noise in Photography

With the visualization we’ve provided above, you’ve learned that you need to increase the ratio between the signal and noise. Here are some techniques to apply it to your photography.

​1. Correctly Expose Your Image

Exposure-compensation

The key to getting very little noise in your photos is to simply expose your images properly. Proper exposure will ensure that your signal strength is much higher than the noise, increasing the ratio between noise and signal.

If you don’t have extremely bright spots that will cause clipping, you can even overexpose your images by a little bit to get a stronger signal in the darker areas. You can then bring down the exposure in Lightroom or your photo editor of choice. You’re better off needing to lower the exposure than needing to increase it, as lowering the exposure also lowers the noise.

Exposure isn’t limited to shutter speed, ISO, and aperture. You can use lights, reflectors, a tripod, and even HDR merging to your advantage to get the right exposure.

​2. Use a Lower ISO

Higher ISOs raise the electrical noise floor by increasing the voltage in the sensor, making it more sensitive. The advantage is that you won’t need long shutter speeds, but at the cost of lowering the signal-to-noise ratio.

Don’t be scared to raise your camera’s ISO, however. Every camera is different; some camera models have less noise at the same ISO levels as other cameras. We suggest experimenting with your camera and finding the highest ISO settings your camera can still have minimal noise at.

A tripod can help you achieve lower ISO shots since you can safely use longer shutter times. However, if you’re shooting handheld, you should try to aim for the lowest ISO you can shoot at. Around 1/(focal length) as a rule of thumb; 1/40th of a second for a 40mm effective focal length, for example. You can go slower if you’re confident with the stability of your own hands, though.

3. Use HDR Merging

HDR merging is a great post-processing technique to use when you have a scene with light ranges that are beyond your camera’s capabilities. HDR merging is basically taking multiple images with different exposures and merging them together to get the most balanced image.

If you have a scene with an extremely bright highlight that clips out before your camera can expose the darker areas properly, HDR merging is extremely useful. You should check to see if your camera has this function already, but if it doesn't, you can use Lightroom to merge them for you. If you don’t use Lightroom, check out how to create HDR images in Photoshop with Camera RAW.

Take these three images above, for example. The first one has a really bright highlight where detail is lost in those areas, the second one has a balanced exposure, and the last is extremely dark but shows the detail in the highlights. We can then combine these in Lightroom, turn down the highlights, increase the shadows, and extract this perfectly exposed image with minimal noise below.

​4. Use Noise Reduction

I’m not a big fan of noise reduction, as it can make images soft and mushy. However, they can be used in moderate amounts to improve an image. You should avoid using it where there’s text, faces, and fine details, as it’ll smoothen those out.

Noise Reduction on Adobe Lightroom sample

Portrait shots, wildlife, landscapes, and the like can all benefit from noise reduction, so long as you don’t overdo it. You can use noise reduction in Photoshop or Lightroom, but AI solutions like Topaz DeNoise also exist and are rapidly improving as well.

​5. Use a Camera With a Larger Sensor

camera sensor closeup

A larger sensor can gather more light, meaning more signal strength to overpower the ambient noise in the system. You generally have more freedom with large sensors in terms of noise, as you can run a lower ISO, a higher aperture, and faster shutter speeds all because of the increased light capture area.

If you want to capture more depth by increasing the aperture, you won’t want to increase your ISO by a lot to reduce the amount of noise, but you also won’t want to lower your shutter speeds or else you’ll end up with a shaky photo. You will still deal with these problems with a larger sensor, but to a lesser degree compared to cropped sensors.

However, we don’t suggest you make your purchasing decisions based on noise performance alone. There are far more things to consider when choosing between a cropped and a full-frame sensor.

​Get Sharper Photos by Reducing Image Noise

Despite newer cameras having amazing noise performance, you’ll find plenty of amazing-looking photos taken with older cameras. When in the right hands, almost every camera has the potential to perform well and have minimal noise. Use this knowledge of signal-to-noise ratio to improve the clarity of your photos at your next photography session.

Here Are The Odds Of Hitting A Deer In NJ: How To Avoid It This Season - Patch

NEW JERSEY — Deer — including especially frisky bucks competing for mates in what’s called “rut” — are making New Jersey’s rural roads, and some more isolated stretches of urban highway, more dangerous at this time of year.

State Farm, the largest auto insurer in the country, said industrywide casualty claims data puts the odds of hitting a deer or other animal at 1 in 213 in the Garden State.

November, October and December, in that order, are the most dangerous time of year for animal collisions.

5 Costly Mistakes To Avoid This Thanksgiving - Nasdaq

ragamnyakabar.blogspot.com

Thanksgiving is around the corner, and a good number of people are planning to host dinner for their friends and family. And while the celebrations are fun and exciting, there’s a lot more that goes into hosting Thanksgiving dinner than just picking out a turkey. There’s a lot of planning, spending and cooking, all of which can be overwhelming if you’re not sure what to expect.

Fortunately, the best way to avoid that anxiety is to plan ahead. By the end of the night, your guests and your wallet will thank you. Here are some mistakes that can make the day harder — and some advice on making sure they don’t bring down your party.

You Didn’t Plan Enough Cooking Time

Depending on how big your turkey is, it can take anywhere from two to six hours to cook. A good rule of thumb is to budget 13 minutes per pound of turkey.

Not sure how much turkey to get? The general recommended amount is about one to one and a half pounds per person. So, if you have 10 people coming, you can be safe with a 10-pound turkey. Just don’t forget, it’ll take two hours and 10 minutes to cook. Buy anything larger and you’re not just looking at wasted time, you’re looking at an emptier wallet, too.

And no turkey dinner is complete without an array of sides to go along with it. Depending on the sides you choose, you could be looking at well over four hours of cook time. Experts recommend taking some time in the days leading up to Thanksgiving to make a list of all your dishes, including ingredients and cook time. This way, you can better plan and even split up preparations between Wednesday and Thursday. On Thursday, you can just warm a few dishes, rather than having to make everything from scratch the day of.

You could also consider purchasing some ready-made side options. While this may feel like you’re spending more money, the time and energy you’ll save will likely outweigh the guilt of not creating everything by hand. Remember: This is a holiday for you to enjoy, too!

You Took on Too Much

Just because you’re hosting doesn’t mean you have to make every dish. If the turkey is stressing you out, and one of your guests has made one before, don’t be afraid to put that person in charge! Ask people to bring dishes that are already prepared. You can also have food delivered or picked up from local restaurants.

Think through what you want to make and what you have time to make — if a dish is making you miserable, ask someone to help. Most likely, they’ll feel happy to contribute. You can even make a spreadsheet with everything you need beforehand. Put your name to what you can comfortably take the lead on, then ask the people coming to fill in the blanks.

Creating such a list won’t just make everyone feel included, it’ll save you money, as well. Hosting is a big financial responsibility, and this is the perfect holiday to allow others to help out.

One more tip: When you’re evaluating which dishes you really want at your celebration, consider skipping the ones that are only on your table thanks to tradition. If no one eats green bean casserole or yams, save the money and time you’d spend on prepping these dishes and put it towards other aspects of your party that everyone will love.

You Don’t Have Any Appetizers

Now that you see how long the meal is going to take, you’ll realize there’s quite a bit of time where guests are just… waiting. To keep people happy, but not totally stuffed, it’s nice to have a few snacks out before the big meal is finished. This can be small — and easily outsourced! — so don’t think too hard about it.

Chips and salsa, pigs in a blanket, meat and cheese boards, veggies and dip, baked brie and crackers and pretty much anything else you like to snack on will do the trick. It’s an easy step to forget in the mix, but it’s a simple thing that makes a big difference.

Need a lot of appetizers on a small budget? You don’t need to break the bank to keep people stuffed from the second they enter your house to the moment they leave. Check out Costco and Trader Joe’s for deals on seasonal favorites. Or consider getting some non-perishable food items from Amazon. If you overstock, you get to keep the leftovers.

You’re Making Something You’ve Never Cooked Before

When it comes to the biggest home cooked meal of the year, stick to the hits. This isn’t a great time to try out a complicated recipe or something that involves a step you’ve never done before. Or worse: a dish that is both complicated and costly to make. Don’t go chasing exotic ingredients right before the holiday. Stick to the apps and mains that you’re used to.

Pick dishes that you’ve gotten good feedback on or just pick up something you think is delicious from the store or a restaurant. Thanksgiving isn’t about who can make the best dish or show off the fanciest spices — it’s just about eating good food with people you care about.

You Invited Too Many People

Maybe you’ve spent the whole month of November extending invites, and now you’ve just realized you’re having 50 people over for Thanksgiving. This isn’t a disaster, but you should be aware of what this means when it comes to cooking and setting the table. With 50 people coming, experts say you’ll need 50 pounds of turkey. And that means you’re going to be spending a lot more money than expected. Not to mention all the dietary preferences you’ll need to accommodate for. And the table space!

Make things easier for yourself and keep your party small and intimate. You’ll make some excellent memories, and your bank account will thank you.

UN retreat from Mali in disarray as violence surges - Reuters

ragamnyakabar.blogspot.com
  • U.N. accelerates withdrawal from Mali as fighting increases
  • Kidal base left to rebels as peacekeepers move out
  • Restrictions by Mali junta jeopardising U.N. troops and kit

DAKAR, Nov 3 (Reuters) - Before United Nations peacekeepers hurriedly abandoned their base in Kidal in northern Mali on Tuesday, they made a costly call: with insurgents stationed nearby, they destroyed sensitive equipment to avoid it falling into the wrong hands, the U.N. said.

Shortly after the last U.N. convoy rolled out, the ethnic Tuareg rebels announced they had taken over the base. Photos posted on social media on Wednesday appeared to show locals loading trucks with looted goods, including tyres, cables and chairs.

Mali's ruling military junta in June ordered the decade-old UN mission, known as MINUSMA, to leave as its relations soured with former international allies. MINUSMA has accelerated its departure in recent weeks as northern Mali has been engulfed in fighting between the rebels and government forces vying for control over areas it vacates.

Chaos has ensued.

Bloody confrontations have surrounded at least two U.N. bases, and two have also been looted, according to two sources with direct knowledge of the withdrawal. At least a dozen peacekeepers have been injured by explosive devices hit by U.N. convoys heading south, according to U.N. statements.

The U.N. has acknowledged difficulties with its departure. MINUSMA said in statements that it has been forced to destroy equipment including vehicles, ammunition and generators that its forces couldn't evacuate after the government imposed restrictions on moving them. Mission spokesperson Fatoumata Sinkoun Kaba told Reuters that millions of dollars of kit has been lost.

Authorities have denied approval for air support for convoys travelling over some of the most volatile terrain in West Africa. They ordered a halt to some imports of fuel and spare parts, and in some cases jeopardised the safety of departing peacekeepers, according to the two sources with direct knowledge of the withdrawal.

Mali's government did not respond to requests for comment for this story.

Security analysts have warned that the Malian state could collapse altogether, further destabilising a region where insurgents with links to al Qaeda and Islamic State are gaining ground.

MINUSMA had originally planned to leave Kidal in mid-November, the sources said. The equipment that was destroyed there and at two other northern bases could have been removed by U.N. trucks earlier, but Mali's junta blocked access, the U.N. said.

Four aircraft have been grounded for lack of parts, the U.N. told Reuters, without specifying what kind of aircraft.

Dozens of U.N. import requests have gone unanswered, the U.N. Department of Peace Operations and the Department of Operational Support said in an internal letter to the Security Council on Oct. 14, seen by Reuters.

With routes to the south under threat from Islamist militants, the mission has explored the possibility of exiting through Algeria to the north or Mauritania to the west, the letter said, both of which were proving "difficult to operationalise".

The two sources, who asked to remain anonymous to speak on a sensitive topic, said they believe Mali's junta has sought to delay the retreat to give it time to reach the bases before the U.N. leaves.

Reuters was unable to confirm this but the junta has expressed concern in public pronouncements about the U.N. leaving bases before it arrives, including after the Kidal departure. Last month, it called the acceleration of MINUSMA's withdrawal a "betrayal".

"NASTY WAR"

The situation marks a bitter end to the U.N.'s mission in Mali, where it deployed after the north was overrun by Islamist militants and Tuareg rebels in a 2012 uprising. MINUSMA initially helped restore some calm, but violence has persisted.

Thousands of civilians have died, and more than 170 peacekeepers have been killed in combat, making MINUSMA the U.N.'s deadliest mission.

Worsening insecurity prompted military coups in 2020 and 2021. The junta then kicked out French troops who were helping fight the Islamists, teamed up with Russian private military contractor the Wagner Group, and ordered MINUSMA to leave.

The mission has until Dec. 31 to pack up. So far, more than 6,000 of nearly 14,000 personnel have left, the U.N. spokeswoman said.

The Tuareg rebels signed a 2015 peace agreement brokered by MINUSMA but maintained control of much of the north from Kidal. That accord has fallen apart since the mission began moving out.

The first sign of trouble came in early August, when fighting broke out between Mali's army and Tuareg rebels around the U.N.'s camp in Ber in the north. The mission left the camp on Aug. 13, two days early. Its convoy was attacked twice that day, injuring four peacekeepers, it said.

In October, gunfire around its base in Tessalit, near the Algerian border, forced peacekeepers to shelter in bunkers, the U.N. said. On Oct. 19, shots hit a MINUSMA plane landing at the airstrip.

When the last troops left Tessalit on Oct. 21, they were denied air support for the nine-day journey across the unpoliced desert.

"They are effectively endangering the lives of our troops," one of the sources said. As in Kidal, peacekeepers destroyed equipment before leaving that could have been transported in trucks earlier, if the government had allowed.

Air support was also denied convoys departing Kidal on a 350-kilometre (217-mile) journey south to the city of Gao, the MINUSMA spokesperson said.

Three security analysts told Reuters that Kidal, a Tuareg stronghold from which rebels have long fought for autonomy of the desert region they call Azawad, was a potential flash point now that the U.N. has left. It is not clear how well positioned the Malian army is to take back the base. It has been trying to reach the city in recent weeks, but progress is slow, the analysts said.

"If the base in Kidal falls into the rebels' hands, this will cause an outcry in Bamako," said Yvan Guichaoua, senior lecturer at the University of Kent's Brussels School of International Studies. "A nasty war may eventually erupt."
