Due to payload constraints, the drone serves a single customer at a time returning back to the dispatching point (DP) after each delivery to load a new parcel for the next customer. In these mixed-areas, called EM-grids, the distances are measured with two different metrics, and the shortest path between two destinations concatenates the Euclidean and Manhattan metrics. In this paper, we present a drone-based delivery system that assumes to deal with two different mixed-areas, i.e., rural and urban. Thus, the battery of the base station can be safely recharged. This charging period is shorter than the mission cycle of the drone, wherein one mission cycle is planned every six hours to collect the data of the sensor nodes distributed in the farm field. The solar panels are sufficient for fully charging the battery of the base station with the required charging voltage (i.e., 24 V) and current (1.667 A) in less than 4.8 h. The battery supplies the ZVS oscillator circuit and the FSC with DC power during the drone's landing. The solar panels are used to charge the base station battery through the DC-DC converter and charger controller. Otherwise, the FSR sensor turns off the charging circuit to keep the ZVS oscillator circuit and the FSC in the off state during a drone mission in the farm field and to save the energy of the base station's battery. When the drone lands on the station, the FSR sensor senses the weight of the drone and turns on the charging circuit. to face the sun (iv) A rechargeable 24 V/7 Ah battery (v) An LM2596 DC-DC converter (vi) A battery charger controller, and (vii) A force-sensitive resistor (FSR) to switch the drone charging on and off.The base station consists of: (i) A 50 cm × 50 cm FSC WPT pad for landing and takeoff (ii) An FSC WPT coil with a 1 A/12-30 V DC input ZVS oscillator circuit (iii) Two 2 × 30 W 60 W/36 V solar panels positioned on the left and right sides of the station frame with an inclination of 30 The height of the station is 2.7 m from the ground. Its interchangeable micro-tethers and smart adaptive winch control laws, allow the operator to reconfigure the station and use the best tether weight/power range for each drone.The base station of the drone. Ready for integrationĮngineered to meet the most demanding missions with its rugged weather-resistant design, and compact modular metallic structure, the Safe-T 2 offers mounting plates and optional software development kit (SDK) for seamless integration into vehicles and fixed structures whilst also being agile enough for a single operator to deploy. Like its predecessor, the Safe-T 2 integrates Elistair’s live flight management system with T-monitor mobile app offering optimal flight control for safer operations. ![]() A patented Brake system also allows the user to adapt the maximal tether length, depending on the safety zone needed around the aircraft, for instance in urban or crowded environments. The secure Dual-Comms option (Fiber optic and BPL), offers a redundant tethered data link, or the possibility to select which technology is best suited for the aircraft and/or payload. The Safe-T 2 has been built on the success of the flagship Safe-T product line which has been deployed in over 60 countries by governmental organizations, industrial groups, and security forces.

![]() The experience might not quite match Adobe’s fluid workflow, but it’s a price you can’t beat.įoxit PDF Editor is a stellar substitute for Adobe Acrobat. ![]() PDF24 Creator is available free and unlimited. Praising Acrobat for its inclusion of tools for almost use-cases, we noted, “the only exception is if you need something more advanced for filling out forms, in which case an editor like PDF24 Creator or PDFZilla (opens in new tab) could work better, despite looking a bit clunkier.” We even felt it bested Adobe in one area. The interface is clean and fresh and emphasizes productivity - you can quickly find what you need and what to do. Extras like OCR and eSign are well-implemented. Tools for PDF creation, compressing, merging, and converting are all present and results are grand. It’s packed full of features, and comes with everything you might need to create and edit a PDF document.” PDF24 Creator isn’t just one of the best Adobe Acrobat alternatives for Windows - it’s also our top pick for best free PDF editor overall.ĭespite the no-cost approach, the tool - a PC-only desktop app that works offline and is ideal for low-spec PCs - is surprisingly feature-rich.ĭuring our time with the software, we rated it as “one of the best examples of free tools that go above and beyond. Volume licensing for businesses is also available. This PDF editing software is capable of running on a PC or a Mac, and costs $180 per license. It also comes with a good OCR, conversion tools.” Ultimately, we found this Adobe Acrobat alternative “a good PDF editing software package that allows you to make changes to documents, annotate them, and perform numerous alterations on them. Everything else is very well implemented, and we especially liked how the ability to convert files to and from PDFs is performed. You have a lot of tools at your disposal, including various ways to make annotations, leaving instructions for colleagues to follow.Įditing the actual content of an already existing PDF isn’t as seamless as we’d like it to be, and that’s probably the weakest tool in Nitro’s arsenal. Other tools to let you make changes to existing PDF documents, and even create one from scratch. The interface and experience make using the software incredibly simple and easy - a factor the sometimes overwhelming Acrobat struggles to boast. When we tried out the product, we found it featured an impressive toolkit that compares favorably with Adobe Acrobat. You won’t find any on-going payment plans with this PDF editor. Nitro PDF Pro is probably the best Acrobat alternative for those who absolutely, positively want to avoid subscriptions at all costs. ![]() A video was uploaded a day later and which he also promotes the non-profit organization, the National Sleeping Foundation.

Better yet, each House is allied with a mystical entity that grants them magical might. In this game, there are 4 Great Houses, clans of samurai who battle against these horrifying monsters. If you’re at all familiar with Japanese myths, you’ll know they have a ton of monsters to contend with, from Yokai to brutal Oni and even spectral Yurei. They all live on the Celestial Islands and defend the floating landmass from demonic incursions. This Mahokenshi review will establish whether this deja vu adventure suffered from the same fate, or found ways to differentiate itself for the better.ĭeveloped by Game Source Studio and published by Iceberg Interactive, Mahokenshi is a tale of fierce samurai. That game ultimately failed to impress me, mainly due to a frustrating lack of pacing and balance. That instantly reminded me of another title I reviewed, Castle Morihisa. It’s a deckbuilder steeped in Japanese mythology with lite randomized elements and plenty of challenge. After all, we all like to think this life is the only one, so why would we suddenly get double vision? Thankfully, deja vu is a lot less disturbing in the video game arena, and it also tends to be less pronounced.Īfter all, plenty of games resemble each other, both intentionally and by pure accident. That nagging sensation you’ve done something before that makes each moment supercharged with mystery and despair. Not just in video games, mind you, but the entire fabric of my life. TLDR: Kaizo then browse the workshop for stuff you want.Mahokenshi Review: Deja Vu and Something Newĭeja vu is a perplexing sensation that I’m more than a little familiar with. You could always pick and choose stuff from Genesis or BaS to add to your mod list though lots of authors jumped ship to Genesis and are no longer updated or are on maintenance mode by Neko. ![]() Blood and sand if you are ok with tons of stuff thrown at you and you want to be Naruto. Genesis if you are ok with just tons of random stuff thrown at you. Recommend Kaizo with your own mod list for a Vanilla Plus experience. Blood and sand is based on Gen modification mod and if Genesis was developed by otakus I guess. Genesis is a bit bloated, there are some stuff included that I disliked when I tried the standalone, it is also still being developed so it will be buggy or unbalanced. The other two are mod lists, I have tried a lot of the mods listed. I mostly play with Kaizo as my base and work from there with mods from the workshop. Hummm I can't really speak for Lost in the Ashlands since I never tried it. Generally recommended not to use with other mods, but god knows there's plenty of forms you can find for that. Also avoid if you like base-building because so many cities means that you lose a LOT of land to build on. Also, it's technically only in Beta, so some things that are planned aren't even added yet. Make sure you have a good CPU or have the patience of a saint. Playing on a laptop (with a decent graphics card mind you) and the load times just to get into the game made me uninstall it. My warning is to avoid it if you don't have a beefy computer. If you are tired of Kenshi this gives you a fresh start. There are more factions, more creatures, more.EVERYTHING. Every city is overhauled and expanded, dozens more added. It's what would have happened if Chris Hunt decided to ignore Kenshi 2, ignore engine upgrades, and put as much shit into Kenshi 1 as the engine can physically hold before breaking down (they literally re-worked code to run more efficiently to let it hold even more). I've heard mixed reviews, and it's much like jamming several parts into a machine and hoping it works, but over time and as mods cease to get updated or change to conflict you may encounter some issues. Other stuff is in the future, so if you want a more over-all experience than war, go with another one.īlood and Sand I've only heard about, but it is a giant mish-mash of an enormous amount of individual mods. Lost in the Ashlands is an incomplete but ambitious as hell mod that adds a bunch of stuff, but right now is basically focused around fighting with the three big factions. It tweaks NPC AI to do things like find and rescue down members of the same faction, add some new possibilities like recruiting Hungry Bandits and Holy Nation Outlaws into your party, and some new World States like helping the Cannibal Hunters retake Deadcat.

The synthetic types of material most commonly used are PET (a type of plastic), PVC (polyvinyl chloride), and polypropylene, as well as proprietary synthetic blends.īoth natural bristles and synthetic bristles come in two main types: flagged and unflagged. Today, bristles can still be made of these plant-based fibers, but most commercial brands use synthetic fibers due to their low cost and high durability. Bristle Type and Brush Angleīroom bristles are traditionally made of stiff, all-natural fibers, including twigs, cornhusks, and plant fibers like yucca, rattan, and ixtle, a fibrous plant native to Mexico. Push brooms are most helpful outdoors when cleaning large swaths of decking, driveways, and walkways. In contrast, push brooms have wide block heads with medium-length bristles that you push away from you. Lobby brooms are mostly used indoors or for light-duty workshop and garage clear-ups. They have long bristles and shallow heads that you pull toward you, rather than push away from you. Lobby brooms are what we typically think of as a traditional broom. Keep the following considerations in mind as you navigate the available options. What to Look for in the Best Broomīuying a broom isn’t always straightforward. ![]() Brooms-particularly those with sturdy synthetic bristles-are better equipped than dust mops to clean rough surfaces like stone, concrete, cement, and brick. However, if you only have space for one, a broom may prove more versatile-especially if it’s a broom intended for both indoor and outdoor use. Many people like to have both a dust mop and a broom on hand. Brooms do require a dustpan unless you intend to sweep debris out the door or into the yard. Microfiber, in particular, is excellent at picking up dust, pollen, and even bacteria from hard surfaces, often without needing to use additional cleaning products or a dustpan. ![]() Long-handled like a broom, a dust mop’s flat head is covered in cotton or microfiber cloth, not regular broom bristles. While brooms are the go-to for sweeping hard floors, dust mops are popular for their ease of use and additional dusting applications.

With some minor change of punctuation, this is the version that was republished by Oliver Ditson in subsequent song books. I nebber shall forget till the day I die, This probably refers to Christy's Minstrels' Ethiopian Glee Book, which has sometimes been mistakenly attributed to 1844 in fact, that series did not begin publishing until 1847 and did not include Christy's version of this song until its 1848 edition. "De Blue Tail Fly" was published by both Keith's Music House and Oliver Ditson in Boston in 1846, but Eric Lott (citing Hans Nathan ) gives the version a date of 1844. The song, however, is also interpreted as having a subtext of celebration about that death and of the slave's having contributed to it through deliberate negligence or even deniable action. ![]() On the surface, the song is a black slave's lament over his white master's death in a horse-riding accident. Most versions include some idiomatic African American English, although General American versions now predominate. Over the years, several variants have appeared. It regained currency as a folk song in the 1940s at the beginning of the American folk music revival and has since become a popular children's song. " Jimmy Crack Corn" or " Blue-Tail Fly" is an American song which first became popular during the rise of blackface minstrelsy in the 1840s through performances by the Virginia Minstrels. ![]() For the song by Eminem, see Jimmy Crack Corn (Eminem song).

If your exposure time is long, you might not notice the drop in lighting as much (you may capture an entire illumination cycle or multiple cycles).īut when shooting at fast shutter speeds under the flickering lights commonly found in indoor and outdoor sports venues, every shot is a bit of a surprise. ![]() The sun is 100% flicker-free and some light types including tungsten and electronic ballast fluorescent approach this performance.īut put a magnetic ballast behind a gas discharge-type lamp and you can prepare for intermittent lighting issues. The more intermittent the light output, the more likely that your very short exposure may be timed to coincide with that light's low cycle. While some lights exhibit very little flicker, some lights are far more intermittent in their output than others. While those lights may appear to be very constant (and they may indeed be above the flicker fusion threshold/rate where intermittent light appears constant to us), they may not be so. The cause of this problem is usually not the camera, but the light themselves. Shooting action sports with a fast frame rate is most frequently the source – most of these images will appear properly exposed but an intermittent dark image glaringly appears. The problem images generating the question have usually been captured under fluorescent or gym/arena lighting and a short exposure was often used. Unfortunately, the resolution of the problem is not as easy as sending the camera in for repair. Most encountering this problem are very concerned that their camera has a problem – perhaps with the shutter.įortunately, the camera is not usually the problem.
