Questions related to Unmanned Aerial Vehicles
I was trying to get an insight into quantum computing (QC) for a research purpose. However, every source was filled with lots of technical terms with less explanation. It becomes very difficult for us those who want to learn QC with no knowledge before.
Is there any source where beginners can learn QC with zero background knowledge?
Thanks in advance.
Will drones evolve as a parcel delivery model or as objects of intelligent logistics networks meaning that they will deliver to distribution centers not to final users?
I was exploring differential privacy (DP) which is an excellent technique to preserve the privacy of the data. However, I am wondering what will be the performance metrics to prove this between schemes with DP and schemes without DP.
Are there any performance metrics in which a comparison can be made between scheme with DP and scheme without DP?
Thanks in advance.

Thanks for your time.
In the data preparation phase, we have to divide the dataset into two parts, such as (1) training and (2) testing/validation part. As there is a sufficient amount of resources regarding computational complexity for DL models while doing the training phase. However, I couldn't find any source that discussed complexity while performing testing/validation after finishing the training process.
Is there any good source for that?
Thanks in advance.
An unmanned aerial vehicle (UAV), also called a drone, is the name for any aircraft that can be operated remotely. Presently, there are various small to large models of drones, and these are being utilized for various applications, including pesticide application, disaster damage surveying, logistics, and media. In Japan, the Ministry of Agriculture, Forestry and Fisheries has prepared the “UAV Stand Inventory Manual” for use in forest surveys, which summarizes specific procedures and key points for stand inventory methods using UAV, and provides a formula to estimate the diameter at breast height (DBH) of trees. However, do you think that it has highest accuracy level. We have used the same for South Bengal Nursery and Sal plantation.
I have a very limited knowledge on control systems. Now my research field is on quadcopters and I want a comprehensive book in this field that can fill all my knowledge gaps on quadcopter sensor fusion techniques and also modeling,system identification and control methods of a quad-copter.
1) What exactly is the definition of a control law and what is the difference between control laws and controllers in the context of aerospace vehicles ?
2) Is the use of the term flight control law specific only to aircraft (fixed wing & rotorcraft) and UAVs, for in my experience the term is not actively used in the context of Launch Vehicles or spacecraft ?
(examples of FCLAW's: images 1 and 2) 
A few questions regarding the control laws of combat aircraft -
3) The Eurofighter(EF 2000) seems to use an interesting control structure - the Differential PI Algorithm, which is also a controller that is being actively used by the naval version of the Indian LCA. My question is, as the controller seems to be quite advantageous, why has'nt the Differential PI structure been used in other flight controllers ? (refer to image 3)
4) The testing of combat flight control laws has made use of test aircraft for in-flight simulation, for example the use of the F-16 VISTA (now X-62 VISTA) to test flight control laws of the Indian LCA. How does this work ? How is useful information to validate & certify the control laws of one aircraft obtained from the flight performance and input responses using these same control laws but on another aircraft ? (refer: VISTA.pdf)
Note: This is not exclusive to aircraft as such, the control laws for the SLS have also been tested on an F/A 18 Hornet.

In order to developp a DL based model for counting and/or other image processing tasks in relation with Palm trees.. I am wondering if you have an idea about types/references of UAV that can be used in this context?
Thank you in advance.
Unmanned Aerial Vehicles are increasingly used for mapping, crop surveillance and scouting purpose in agriculture. I seek views on following.
1. How effectively Unmanned Aerial Vehicles could be used for pesticide application for plant protection purposes.
2. What are the possible risks involved?
3. What are the expected challenges before regulatory system?
I am going to buy an unmanned aerial vehicle for my university for forestry applications. Since there are alot of options, I realy get confused to choose a proper model and a valid brand. Also, l want to use a 3d laser scanner and a multispectral camera. I would rather that the vehicle have gps and imu and the flight could be programmed. Please if you have personal experience, share them.
How can I estimate the propagation loss between an unmanned aerial vehicle (UAV) or drone, and user equipment (UE) on the ground? is it safe to assume a line-of-sight scenario? how about the drone's altitude? is there a specific air-to-ground formula I can use?
Recently, UAV attracted a many researcher to apply them in agriculture because of their flexibility, cost and availability. Many published work can be found on application of UAV in various agriculture applications such as disease scouting, crop monitoring, spraying(pesticide and other agronomic inputs), yield estimations, and plant phenotyping. However, there are some challenges associated with UAV, such as standard data processing pipelines, limitation on area coverages and load carrying capacity etc.
In this discussion, I would expect your views regarding future of UAV in agriculture applications and how they will emerge and used in this field.
I have been through some discussion regarding survey paper writing tips and tricks. However, these are very generic. I want to know how to write a survey paper related to computer science topics (e.g., blockchain,.internet of things, so on). I have some following queries regarding the aforementioned concerns.
- How to design the flow of the survey paper?
- What will be the minimum length of the survey paper?
- How to pick up a reference paper and which criteria should be the first concern while selecting it? What is the minimum number of references that should I pick?
- Is it necessary to propose an idea in the paper? If yes then is it necessary to show a performance evaluation of the proposed scheme?
- While writing a survey paper which things should I focus on or care about?
Please share your experience regarding this.
Thanks for your time and input.
Thanks in advance.
Is there a group of crucial and important UAV's parameters/features regardless of kind of mission (search missing people, disaster, evacuation, emergency deliveries, monitoring, fight a fire, training, saving trapped people, contamination, flying rescue cushion)? Or maybe every kind of mission has their own crucial parameters/features?
* Are drones following the e-Auto industry technological trajectory or it is following its own?
* Will drones diffuse faster than electrical vehicles?
* Will it depend on the application?, What about delivery of medical supplies?
Can you recommend us the equipment to acquire high-resolution LiDAR data, acquired from an unmanned aerial vehicle (UAV) after the fire?
We are planning to buy LiDAR and an unmanned aerial vehicle (UAV).
The idea is using of the LiDAR to measure the remaining tree structures after a fire in a forest stand burned. We are planning to use high-resolution LiDAR data, acquired from an unmanned aerial vehicle (UAV) after the fire. This information will be crossed with fire severity levels based on the relativized burnt ratio (RBR) derived from Sentinel 2A images acquired a few months before and after fire.
Can you recommend us specific equipment based on your experience?
What could be budget estimation for such equipment? EUR 20,000?
Looking forward to your advice.

Does it has do to with the related enabling technologies?
I have aerial photographs taken by an Unmanned Aerial Vehicle (UAV). I want to look into details to find my target by zooming on the TIff images. Which open-source tool would be effective for the processing of aerial images? Thank you.
What UAVs (drones, quadcopters, blimps, etc.) are most cost-effective for monitoring/mapping small areas of emergent and submerged aquatic vegetation ?
As we have seen that most powerful and expensive quadcopters being swept away by prevailing wind gusts and losing connection with the controller, and even that “fail-safe” GPS-enabled Return To Home feature will struggle and oftentimes fail when flying into a strong headwind.
How to make it reliable and robust for sever weather conditions?

Is UAV (unmanned aerial vehicle) for pesticide application and how much is its efficency of depostion compared to conventional spraying?
In India, Where mainly water based pesticides are used and the farmers residence are within or nearby the pesticide application zone.Is it safe to use drones for pesticides application.
I want to estimate glacier surface lowering using UAV data acquired on glacier frontal areas where it is too difficult and dangerous to measure GCPs.
Nowadays, urban population is witnessing an unprecedented sharp increase, as cities are the centers of education, innovation, culture and opportunities.
Smart measures should be taken to guarantee a good quality-of-life for the dwellers.
In the transportation domain, do you think that the Unmanned Aerial Vehicles (UAVs) have a role in these measures? and when do you expect such a role?
Thanks for sharing your ideas.
hello In principle, commercial software is nowadays used to produce orthophones from drones. What do you think is the major difference between these commercial software? Do they have significant advantages and disadvantages in addition to the algorithm used? Which of the following commercial software do you recommend for the UAV?
In the literature many researchers proved their communication schemes/protocols using assumptions or theorem, here I mean is any software tool(s) available to practically prove that the protocol is robust and resists all known attacks?

Unmanned aerial systems and other remote sensing equipments have gained much popularity among agriculturists, especially plant breeders. The remote sensing techniques, especially the use of drones have shown a positive impact in field-phenotyping and plant breeding. But, is there any disadvantage of using such techniques in plant breeding/agricultural research? If so, what are they and how other method(s) can replace the use of drones?
Is it correct to use a term "drone/UAV special for fire service/fire brigades"? Or are there only a adaptations/modifications of available models (like adaptations of Matrice - see https://www.dslrpros.com/inspire-1-first-responder-thermal-kit.html https://www.rmus.com/collections/police-fire-search-and-rescue-drones)?
It took me quit significant amount of time searching for this. I figure out how to do it. Thought it might be use full for you as well.
Resolution chart is a chart that you need to lay in the field while you are doing the imagery session. Better to put it in the middle of the field where it can be seen in several images.
Here is what we designed for the resolution chart: You need to print it in 1.0*1.2 m if you are usually flying 80 to 150 meters. I also attached the powerpoint format so you can change the size or targeted resolutions as you wish (remember to change the names 📷😉). If you fly higher you need a larger and you fly lower you need a smaller chart.I also added the powerpoint format so you can change it as you wish. The standards of USAF is: The length of each element should be 5 times larger than the width. Three horizontal and three vertical rectangular elements make a group. If you can see the element of a group, the width of the element is the true resolution. In the attached figure, if you only can separate the elements of the largest group, the true resolution of your imagery is 8 cm. If you can see the elements of the smallest group, the true resolution will be 1 cm. Also, horizontal and vertical elements of the groups can show if your horizontal or vertical resolution on the camera in the mission is different or not.
What are the latest restrictions by the FAA on using UAVs ( fixed wing and rotary wing, e.g quadcopters) for purely scientific investigations?
Max.altitude, line-of-sight, permits, coastal and urban areas, etc.
What are the methods and procedures to create variable rate nitrogen fertilizer map from UAV remote sensing data.
1) Which data (green band, red band, red-edge, NDVI, RGB) is most suitable?
2) How can we do this?
3) How effective is using UAV data for this purpose?
Thanks in advance for sharing your knowledge?
Could you please share your experience on the interpretation of red edge data in UAV remote sensing.
We recently used a drone with a camera with green, red, NIR, red edge and RGB spectrums.
I am confused about the meaning of red edge data: That is to say;
Is the data from the red edge spectrum/ band a kind of reflectance at a specific band? If so what is the wavelength range?
Or Is it the wavelength at which the reflectance curve sharply rises from red band to NIR band?
And also how to interpret the data?
Thanks in advance.

Hello all, I am a PhD student and I work on the Quadrotors UAV, I would like to ask you about new subjects and ideas about the control and the trajectory planning for the UAV, thanks
I would need this information to know what are the key planning and design considerations to look out for and what are the technical parameters to consider while planning a High Speed Rail track routing.
Any form of help is much appreciated, thank you.
I need for my research about outdoor positioning system/gis to extract coordinate pointing become map sketch. It will be useful with map scale when extract this coordinate become map sketch. Can anyone suggest me some paper or research about this? thanks in advance.
Is it required to have an FAA certification to operate a UAV or Drone) if its for research purpose only. I know for educational and recreational purpose if UAV is less that .55lb, it's not required but does research come under education?
Also, what if I want to fly it indoors in a big lab environment, do you still need to be certified?
I am looking for a programmable quad-rotor UAV for academic application (Control). Do you have any good suggestion?
PS: The ability to be controlled with MATLAB/SIMULINK would be an asset.
I have conducted a survey of ground control points with a Trimble RTK system relative to a base station at an unknown location. I need to correct the base station position using the Natural Resources Canada CSRS-PPP application (I am trying to compare to another dataset which has used this same correction). The output of the CSRS-PPP is a .csv file with the corrected base station position for each time stamp during the survey. I don't know how to integrate that with the raw rover and base station files from the survey.
I want to use the nonlinear model of the "Ultra Stick 25E RC" aircraft. there is a missing parameter which is the thrust Tm. Several works have been developed above, I want to know where they found it.
We got a small UAV and equipped it with an camera to monitor the wheat growth status.
Could anybody please give me some tips on how to introduce these remote sensing images into GIS analysis, such like add coordinate systems or something?
What are the simulation tools or software that can be used for testing the algorithms of an Unmanned Aerial Vehicle path planning,speed, efficiency, collision avoidance?
Currently Unmanned Aerial Vehicles (UAV) are heavily researched in computer vision and photogrammetry for several interesting and exciting applications, but security restrictions may hamper their practical use in the near future. Is there any line of technological thinking that may help to mitigate and address the security restrictions without compromising the safety of the public?
