This function take as list of transformations as an argument. Thesetransformations are functions that will be called by the Reader and givena Timestep object as argument, which will be transformed and returnedto the Reader.The transformations can be part of the transformationsmodule, or created by the user, and are stored as a list transformations.This list can only be modified once, and further calls of this function willraise an exception.
This time zone converter lets you visually and very quickly convert IST to Beijing, China time and vice-versa. Simply mouse over the colored hour-tiles and glance at the hours selected by the column... and done!
These formats are essentially base R object classes and can be usedas such. For example, a draws_matrix object is just amatrix with a little more consistency (e.g., no dropping ofdimensions with one level when indexing) and additional methods. Theexception to this is the draws_rvars format, which containsrvar objects that behave somewhat like arrays but arereally a unique data type. See the separate vignette on thervar and draws_rvars data types fordetails.
Each of the formats has a method as_draws_(e.g., as_draws_list()) for creating an object of the classfrom any of the other formats. As a demonstration we can convert theexample draws_array to a draws_df, a dataframe with additional meta information. To convert to adraws_df we use as_draws_df().
Instead of as_draws_matrix() we also could have justused as_draws(), which attempts to find the closestavailable format to the input object. In this case the result would be adraws_matrix object either way.
The posterior package provides many methods for manipulating drawsobjects in useful ways. In this section we demonstrate several of themost commonly used methods. These methods, like the other methods inposterior, are available for every supported draws format.
Subsetting draws objects can be done according tovarious aspects of the draws (iterations, chains, or variables). Theposterior package provides a convenient interface for this purpose viasubset_draws(). For example, here is the code to extractthe first five iterations of the first two chains of the variablemu.
As with all posterior methods, bind_draws() can be usedwith all draws formats and depending on the format different dimensionsare available to bind on. For example, we can binddraws_array objects together by iteration,chain, or variable, but a 2-Ddraws_matrix with the chains combined can only by bound bydraw and variable.
Closest focus distance is 4.94m (16.2ft.) with a working distance of 4.54m (14.9ft.) and a maximum magnification of 1:5.8 which is not much but similar to what the F-Nikkor offers. A magnification of 1:10 is achieved at 8.34m object distance. The Z 400/2.8 + TC-2.0x achieves a magnification of 1:2.8 at 2m working distance, the Canon RF goes down to 2.6m offering a maximum magnification of 1:2.94. [0]
Use with teleconverters: Yes, the Z 800/6.3 can be used with the Z TC-1.4x and Z TC-2.0x, just like the Z 400/2.8 (which has a 1.4x teleconverter already built-in). Keep in mind though that the Z TCs cannot be used with the FTZ adapter. The F-Nikkor comes with the special TC800-1.25E ED included converting it into a 1000mm f7 lens. [+]
MODFLOW 6 is an object-oriented program and framework developed to provide a platform for supporting multiple models and multiple types of models within the same simulation. This version of MODFLOW is labeled with a "6" because it is the sixth core version of MODFLOW to be released by the USGS (previous core versions were released in 1984, 1988, 1996, 2000, and 2005). In the new design, any number of models can be included in a simulation. These models can be independent of one another with no interaction, they can exchange information with one another, or they can be tightly coupled at the matrix level by adding them to the same numerical solution. Transfer of information between models is isolated to exchange objects, which allow models to be developed and used independently of one another. Within this new framework, a regional-scale groundwater model may be coupled with multiple local-scale groundwater models. Or, a surface-water flow model could be coupled to multiple groundwater flow models. The framework naturally allows for future extensions to include the simulation of solute transport.
Centimeters to inches converter will display the conversion value from the unit centimeters to inches. As soon as the centimeter value is entered in the input field, the corresponding inches value will be displayed in the output field in a fraction of seconds.
In the previous notebook, we learned how to be more productive with Pandas by using sophisticated multi-level indexing, aggregating and combining data. In this notebook, we will explore the capabilities for working with Time Series data. We will start with the default datetime object in Python and then jump to data structures for working with time series data in Pandas. Let's dive into the details.
datetime objects can be used to quickly perform a host of useful functionalities. A date can be built in various ways and then properties of a datetime object can be used to get specific date and time details from it.
strftime can be used to convert a datetime object to a string according to a given format. Standard string format codes for printing dates can read about in the strftime section of Python's datetime documentation.
Pandas provides a Timestamp object, which combines the ease of datetime and dateutil with the efficient storage of numpy.datetime64. The to_datetime method parses many different kinds of date representations returning a Timestamp object.
DatetimeIndex objects do not have a frequency (hourly, daily, monthly etc.) by default, as they are just snapshots in time. As a result, arithmetic operations such as addition, subtraction, or multiplication cannot be performed directly.
Pandas also supports converting integer or float epoch times to Timestamp and DatetimeIndex. The default unit is nanoseconds, since that is how Timestamp objects are stored internally.
Time deltas represent the temporal difference between two datetime objects. Time deltas come in handy when you need to calculate the difference between two dates. A TimedeltaIndex can be easily created by subtracting a date from dates.
pd.period_range() generated eight periods with monthly frequency. Note that the output is a PeriodIndex object. As mentioned earlier, Period represents an interval in time, whereas Timestamp represents a point in time.
There is no need for a.m. or p.m. as each time represents each hour in a 24-hour day. For example, 0300 = 3rd hour of the day, or 3am; 1400 = 14th hour of the day, or 2pm; 1830 = 30 minutes past the 18th hour of the day, or 6.30pm.
You can listen to lossless audio using the latest Apple Music app on an iPhone, iPad, Mac, or Apple TV 4K. Turn on lossless audio in Settings > Music > Audio Quality. You can choose between Lossless and Hi-Res Lossless for cellular or Wi-Fi connections. Note that Hi-Res Lossless requires external equipment such as a USB digital to analog converter.
