I have a database of weather information that I need to filter by a range of years. I know how to do that. Then I need to filter by a certain time of day. From noon to six pm. So essentially I need to find every row that occurred from 2000 - 2005 and from 12pm to 6pm. I can't for the life of me figure out how to filter the time. The column is not date time. It is just time in the hh:mm:ss format.

I am trying to create a page where the second input box formats someone's first, middle, and last name put in to first intial, middle name, last initial. So for example if someone puts in "Will Joe Smith" the output will be W. Joe S. and it will appear next to the input box. I'm completely stuck on the function for this though. Here is what I have so far:

I am very new to spatial evaluation and come from psychology.

I am using the software R and the packages "gstat" and "spacetime".

I would like to do a spatio temporal interpolation. For this I follow the paper of Gräler et al. (https://cran.r-project.org/web/packages/gstat/vignettes/spatio-temporal-kriging.pdf)

Unfortunately I can't find/fit the right variogram model. I can create the empirical variogram and this is also conclusive to me, but then I do not get any further. I do not understand how to define the individual parameters such as "sill" or "nugget" or what they stand for.

Here are my previous approaches:

I am using Flutter framework and I am trying to run multiple Stateless widgets, a bottom navigation bar and a top appbar to hold menu and other navigation buttons. I am struggling to get both running at once and I can not find a way to run them both. At the moment, when I call home:MyBottomNavigationBar only this appears and not the other(Makes sense) But what command or solution would help me run multiple widgets? I have tried tons of different ways to use home, but nothing seems to work. My code is very simple. Just creating a Navigation bar and appbar with stf inside main.dart.

If needed I can attach the code, but hopefully my question is clear enough.

Done In Xamarin, I can have both BottomNavBar and Couple of Nav buttons at the top easily. [1]: https://i.stack.imgur.com/Q2qXg.png

I want to reduce a list of adbKeys if there are duplicated title. I want to keep the latest, or the last, value in a list.

I have the following table with date range:

I have a Linq To SQL result which is a list of objects representing staff. There are duplicate staff records if the staff member is registered to more than one location. In the case of multiple staff records, I need to comma separate those locations in "location" so that I now have one staff record. Here is the select statement:

All solutions point to the fact that if I've assigned aliases in my code, I should be using them instead of the table name itself. I have assigned alias and I AM trying to use the alias, however, I am still receiving this error.

Does this have to do with using an left join?

My code is as follows:

I need an app to create Notifications, which should be there after the app is closed, for another app should read them after some time passes.

I followed a tutorial: https://www.youtube.com/watch?v=UqR7YinI7k4

And later, found out, that I need another implementation, due to higher SDK version.

I came to find this answer, which states, that I need to use a NotificationChannel, to do this:

Failed to post notification on channel "null" Target Api is 26

But, I still got stuck, here is my code:
