Experimental Measurement and Thermodynamic Modelling of Vapor-Liquid Equilibria Correlations for Prediction Azeotropic Behavior and Fitting Multicomponent Mixtures Data_Crimson Publishers

Abstract:

In this study, isobaric vapor-liquid equilibrium for two ternary systems: "1-Propanol-Hexane-Benzene” and its binaries "1-Propanol-Hexane, Hexane-Benzene and 1-Propanol-Benzene” and the other ternary system is "Toluene-Cyclohexane-iso-Octane (2,2,4-Trimethyl-Pentane)” and its binaries "Toluene-Cyclohexane, Cyclohexane-iso-Octane and Toluene-iso-Octane” have been measured at 101.325KPa. The measurements were made in re-circulating equilibrium still with circulation of both the vapor and liquid phases. The ternary system "1-Propanol-Hexane-Benzene” which contains polar compound (1-Propanol) and the two binary systems "1-Propanol-Hexane and 1-Propanol-Benzene” form a minimum azeotrope, the other ternary system and the other binary systems do not form azeotrope.

Correlation equations for expressing the boiling temperature as direct function of liquid composition have been tested successfully and applied for predicting azeotropic behavior of multi component mixtures and the kind of azeotrope (minimum, maximum and saddle type) using modified correlation of Gibbs-Konovalov theorem. Also, the binary and ternary azeotropic point has been detected experimentally using graphical determination on the basis of experimental binary and ternary vapor-liquid equilibrium data.

All the data passed successfully the test for thermodynamic consistency using McDermott-Ellis test method [1]. The maximum likelihood principle is developed for the determination of correlations parameters from binary and ternary vapor-liquid experimental data which provides a mathematical and computational guarantee of global optimality in parameters estimation for the case where all the measured variables are subject to errors and the non ideality of both vapor and liquid phases for the experimental data for the ternary and binary systems have been accounted. The agreement between prediction and experimental data is good. The exact value should be determined experimentally by exploring the concentration region indicated by the computed values.

Testing the ?? operator in PHP

The ?? operator was introduced to PHP with PHP 7.0, but sadly I haven't been using it very much - and the other day I realized that I haven't seen it around much either.

?? is one of the most significant bits of syntactical sugar that PHP introduced when it added the new operators to PHP7, it basically means that something like this:

$id = isset($_GET['id']) && !empty($_GET'id'])? $_GET['id'] : false;

Can now be written with a much less repetitive and much more expressive statement that looks like:

$id = $_GET['id']?? false;

It looks much better, doesn't it? It's so much stronger and more readable that it seems like a no-brainer for people to use it. But still, it's 2019, PHP7 has been around for years and I still get to read recent code that is not taking advantage of it.

I made a mental note to start using it more, and have realized that the thing keeping me from using it was the fact that I wasn't sure if it would work exactly the same way as the long bulky statement.

I wrote a few tests to ensure that it was compatible with magic methods of objects and the ArrayAccess interface. We use them quite often to write more readable code, and they've been a regular source of headaches in the past. Here's the script I used: https://3v4l.org/v7YYP

Conclusion

I am happy to report that ?? is virtually identical to the long ternary expression that (sometimes also the if statement) that people are using. And it also does not raise those Undefined index errors when reading your input variables.

7 am thought: is there a worse syntactic decision ever made in a popular programming language than matlab having "..." as its line continuation operator? like okay php's ternary operator being left-associative is definitely much worse but i'm thinking more in terms of symbol choice (i.e. vocabulary) than grammar. is there anything less convenient than needing to set aside 4 entire characters to continue a line?

having "<-" as the assignment operator in r is up there i guess but i think "..." is still worse since it's one character longer and explicitly goes in a place where you're by definition already running out of space

i wonder if the decision to make macros syntactically indistinguishable from functions in lisp counts. it killed the entire language family

…but it was also considered lisp's greatest feature so idk

Best way to prepare for PHP interview

PHP is one among the programming languages that are developed with built-in web development functions. The new language capabilities contained in PHP 7 ensure it is simpler for developers to extensively increase the performance of their web application without the use of additional resources. interview questions and answers topics for PHP They can move to the latest version of the commonly used server-side scripting language to make improvements to webpage loading without spending extra time and effort. But, the Web app developers still really should be able to read and reuse PHP code quickly to maintain and update web apps in the future.

Helpful tips to write PHP code clean, reliable and even reusable

Take advantage of Native Functions. When ever writing PHP code, programmers may easily achieve the same goal utilizing both native or custom functions. However, programmers should make use of the built-in PHP functions to perform a number of different tasks without writing extra code or custom functions. The native functions should also help developers to clean as well as read the application code. By reference to the PHP user manual, it is possible to collect information about the native functions and their use.

Compare similar functions. To keep the PHP code readable and clean, programmers can utilize native functions. However they should understand that the speed at which every PHP function is executed differs. Some PHP functions also consume additional resources. Developers must therefore compare similar PHP functions and select the one which does not negatively affect the performance of the web application and consume additional resources. As an example, the length of a string must be determined using isset) (instead of strlen). In addition to being faster than strlen (), isset () is also valid irrespective of the existence of variables.

Cache Most PHP Scripts. The PHP developers needs keep in mind that the script execution time varies from one web server to another. For example, Apache web server provide a HTML page much quicker compared with PHP scripts. Also, it needs to recompile the PHP script whenever the page is requested for. The developers can easily eliminate the script recompilation process by caching most scripts. They also get option to minimize the script compilation time significantly by using a variety of PHP caching tools. For instance, the programmers are able to use memcache to cache a lot of scripts efficiently, along with reducing database interactions.

Execute Conditional Code with Ternary Operators. It is actually a regular practice among PHP developers to execute conditional code with If/Else statements. But the programmers want to write extra code to execute conditional code through If/Else statements. They could easily avoid writing additional code by executing conditional code through ternary operator instead of If/Else statements. The ternary operator allows programmers to keep the code clean and clutter-free by writing conditional code in a single line.

Use JSON instead of XML. When working with web services, the PHP programmers have option to utilize both XML and JSON. But they are able to take advantage of the native PHP functions like json_encode( ) and json_decode( ) to work with web services in a faster and more efficient way. They still have option to work with XML form of data. The developers are able to parse the XML data more efficiently using regular expression rather than DOM manipulation.

Replace Double Quotes with Single Quotes. When writing PHP code, developers are able to use either single quotes (') or double quotes ("). But the programmers can easily improve the functionality of the PHP application by using single quotes instead of double quotes. The singular code will speed up the execution speed of loops drastically. Similarly, the single quote will further enable programmers to print longer lines of information more effectively. However, the developers will have to make changes to the PHP code while using single quotes instead of double quotes.

Avoid Using Wildcards in SQL Queries. PHP developers typically use wildcards or * to keep the SQL queries lightweight and simple. However the use of wildcards will impact on the performance of the web application directly if the database has a higher number of columns. The developers must mention the needed columns in particular in the SQL query to maintain data secure and reduce resource consumption.

However, it is important for web developers to decide on the right PHP framework and development tool. Presently, each programmer has the option to decide on a wide range of open source PHP frameworks including Laravel, Symfony, CakePHP, Yii, CodeIgniter, and Zend. Therefore, it becomes necessary for developers to opt for a PHP that complements all the needs of a project. interview questions on PHP They also need to combine multiple PHP development tool to decrease the development time significantly and make the web app maintainable.

PHP is one amongst the programming languages that were developed with inbuilt net development capabilities. The new language options enclosed in PHP seven any makes it easier for programmers to boost the speed of their net application considerably while not deploying extra resources. They programmers will switch to the foremost recent version of the wide used server-side scripting language to enhance the load speed of internet sites while not swing beyond regular time and energy. however the net application developers still want target the readability and reusability of the PHP code to take care of and update the net applications quickly in future.

12 Tips to write down Clean, rectifiable, and Reusable PHP Code

1) benefit of Native Functions While writing PHP code, the programmers have choice to accomplish identical objective by victimisation either native functions or custom functions. however the developers should benefit of the inbuilt functions provided by PHP to accomplish a spread of tasks while not writing extra code or custom functions. The native functions can any facilitate the developers to stay the appliance code clean and decipherable. they'll simply gather info concerning the native functions and their usage by touching on the PHP user manual.

Another way to check phpstorm key shortcuts

2) Compare Similar Functions The developers will use native functions to stay the PHP code decipherable and clean. however they need to keep in mind that the speed of individual PHP functions differs. Also, bound PHP functions consume extra resources than others. Hence, the developers should compare similar PHP functions, and select the one that doesn't have an effect on the performance of the net application negatively and consume extra resources. as an example, they need to verify the length of a string by victimisation isset() rather than strlen(). additionally to being quicker than strlen(), isset() conjointly remains valid in spite of the existence of variables.

3) Cache Most PHP Scripts The PHP programmers should keep in mind that the script execution time differs from one net server to a different. as an example, Apache net server serve a HTML page abundant quicker than PHP scripts. Also, it has to recompile the PHP script on every occasion the page is requested for. The programmers will simply eliminate the script recompilation method by caching most scripts. They even have choice to scale back the script compilation time considerably by employing a style of PHP caching tools. as an example, the programmers will use memcache to cache an oversized variety of scripts expeditiously, at the side of reducing info interactions.

4) Execute Conditional Code with Ternary Operators It is a typical observe among PHP developers to execute conditional code with If/Else statements. however the developers got to writing extra code to execute conditional code through If/Else statements. they'll simply avoid writing extra code by corporal punishment conditional code through ternary operator rather than If/Else statements. The ternary operator helps programmers to stay the code clean and clutter-free by writing conditional code during a single line.

5) Keep the Code decipherable and rectifiable Often programmers notice it intimidating perceive and modify the code written by others. Hence, they have beyond regular time to take care of and update the PHP applications expeditiously. whereas writing PHP code, the programmers will simply build the appliance simple to take care of and update by describing the usage and significance of individual code snippets clearly. they'll simply build the code decipherable by adding comments to every code piece. The comments can build it easier for alternative developers to form changes to the present code in future while not swing beyond regular time and energy.

6) Use JSON rather than XML While operating with net services, the PHP programmers have choice to use each XML and JSON. however they'll continuously benefit of the native PHP functions like json_encode( ) and json_decode( ) to figure with net services during a quicker and a lot of economical manner. They still have choice to work with XML style of information. The programmers will break down the XML information a lot of expeditiously by victimisation regular expression rather than DOM manipulation.

7) Pass References rather than worth to Functions The intimate PHP programmers ne'er declare new categories and strategies only if they become essential. They conjointly explore ways in which to recycle the categories and strategies throughout the code. However, they conjointly perceive the actual fact that a perform may be manipulated quickly by passing references rather than values. they'll any avoid adding additional overheads by passing references to the perform rather than values. However, they still got to make sure that the logic remains unaffected whereas passing relevancy the functions.

8) flip Error coverage on in Development Mode The developers should establish and repair all errors or flaws within the PHP code throughout the event method. They even have to place overtime and energy to mend the writing errors and problems known throughout testing method. The programmers merely set the error coverage to E_ALL to spot each minor and major errors within the PHP code throughout the event method. However, they need to flip the error coverage choice off once the appliance moves from development mode to production mode.

9) Replace inverted comma with Single Quotes While writing PHP code, programmers have choice to use either single quotes (') or inverted comma ("). however the developers will simply enhance the performance of the PHP application by victimisation single quotes rather than inverted comma. the only code can increase the speed of loops drastically. Likewise, the only quote can any change programmers to print longer lines of data a lot of expeditiously. However, the developers got to build changes to the PHP code whereas victimisation single quotes rather than inverted comma.

10) Avoid victimisation Wildcards in SQL Queries PHP programmers typically use wildcards or * to stay the SQL queries compact and easy. however the employment of wildcards might have an effect on the performance of the net application directly if the info includes a higher variety of columns. The programmers should mention the desired columns specifically within the SQL question to stay information secure and scale back resource consumption.

11) Avoid corporal punishment info Queries in Loop The PHP programmers will simply enhance the net application's performance by not corporal punishment info queries in loop. They even have variety of choices to accomplish identical results while not corporal punishment info queries in loop. as an example, the developers will use a strong WordPress plug-in like question Monitor to look at the info queries at the side of the rows laid low with them. they'll even use the debugging plug-in to spot the slow, duplicate, and incorrect info queries.

12) ne'er Trust User Input The sensible PHP programmers keep the net application secure by ne'er trusting the input submitted by users. They continuously check, filter and sanitize all user info to guard the appliance from varied security threats. they'll any forestall users from submitting inappropriate or invalid information by victimisation inbuilt functions like filter_var(). The perform can check for applicable values whereas receiving or process user input.

However, it's conjointly necessary for the net developers to select the correct PHP framework and development tool. At present, every technologist has choice to choose between a large vary of open supply PHP frameworks as well as Laravel, Symfony, CakePHP, Yii, CodeIgniter and Iranian language. Hence, it becomes essential for programmers to select a PHP that enhances all wants of a project. They conjointly got to mix multiple PHP development tool to scale back the event time considerably and build the net application rectifiable.

PHP Conditional Statements: Very often when you write code, you want to perform different actions for different conditions. You can use conditional statements in your code to do this. In PHP we have the following conditional statements: if statement - executes some code if one condition is true if...else statement - executes some code if a condition is true and another code if that condition is false if...elseif...else statement - executes different codes for more than two conditions Ternary Operators In addition to all this conditional statements, PHP provides a shorthand way of writing if…else, called Ternary Operators. The statement uses a question mark (?) and a colon (:) and takes three operands: a condition to check, a result for TRUE and a result for FALSE. #php #code #coding #phpdevelooer #developer #afgprogrammer #codesnippet #phpprogramming https://www.instagram.com/p/CLRhNqpjQyn/?igshid=msos8smu9fd3

If the structure is one of the most important and essential features in a computer programming language. The if statement in PHP helps us to execute the code fragments conditionally. This structure is almost similar to the if the structure in C. If statement in PHP returns a boolean value as a result, either true or false.

PHP empty() function use with MySQL NULL

PHP provides a handy function, empty(), that is used to determine whether a variable is empty. Perhaps that is a bit confusing to someone unfamiliar with the empty() function and I can see how. In this blog post, I will cover: what empty() means in PHP, what the empty() function does, and a use case pairing up empty() with the PHP ternary operator conditional construct. Both used in combination with the MySQL NULL value. Continue reading and see examples of empty()… Photo by Debby Hudson on Unsplash Self-Promotion: If you enjoy the content written here, by all means, share this blog and your favorite post(s) with others who may benefit from or like it as well. Since coffee is my favorite drink, you can even buy me one if you would like! I’ll use these various variables for examples throughout the post: $name = 'Josh'; $another_name = NULL; $some_name = ''; $an_age = 0; $another_age = '0'; $different_age = 12; Before we see what values are returned when the above variables are passed to empty(), let’s visit the PHP documentation on empty() for additional information, that way we know what to expect. Here is the description: “Determine whether a variable is considered to be empty. A variable is considered empty if it does not exist or if its value equals FALSE. empty() does not generate a warning if the variable does not exist.” empty() returns a value – either TRUE or FALSE – depending on if the variable that is passed to empty() as an argument exists and is either non-empty or non-zero. So what exactly is non-empty and non-zero? Let’s find out… Echo PHP empty() function in the browser For more context, I’ll echo out the return values of each of the below calls to empty(), passing in the previously defined variables above as arguments in each call: echo '$name variable empty value is: '.empty($name).' '; echo '$another_name variable empty value is: '.empty($another_name).' '; echo '$some_name variable empty value is: '.empty($some_name).' '; echo '$an_age variable empty value is: '.empty($an_age).' '; echo '$another_age variable empty value is: '.empty($another_age).' '; echo '$different_age variable empty value is: '.empty($different_age).' '; Return results from empty echo’ed in the browser Understanding PHP empty() function What does empty consider to be empty? empty() considers any of these values to be empty: The empty string – “” The integer 0 (zero) The float 0.0 The string “0” The NULL value. The FALSE boolean An empty array(). Based on the above list, the first variable, ‘$name’, and the last variable ‘$different_age’, are not considered empty, as they both have actual values (none of which are those included on the empty list). When passed to empty() as arguments, both variables return FALSE whereas all of the other variables return TRUE. In PHP, a FALSE can be considered 0 (zero) where a TRUE value can be considered 1. For more information on PHP booleans, visit the online PHP Booleans documentation. In order to see the actual boolean result, we can use the var_dump() function, passing the empty() function call with the variable parameter as var_dump()‘s own parameter: echo var_dump(empty($name)).' '; echo var_dump(empty($another_name)).' '; echo var_dump(empty($some_name)).' '; echo var_dump(empty($an_age)).' '; echo var_dump(empty($another_age)).' '; echo var_dump(empty($different_age)).' '; Using var_dump to echo out boolean values. What can we use the PHP empty() function for? Now that we have an idea of what empty() does, we can use it in a simple example and see the benefits of such a handy function. I have recently used an empty() trick in a LAMP stack application I have been working on and just had to share it here on my blog (although it is by no stretch of the imagination, sacred knowledge). Suppose we have this MySQL table, structure, and data: Current data in the project_pdf table The requirement is, provide a simple button for each project name in the table. However, each rows’ button should only be clickable if there is a pdf document file for that projects’ table row. We can use empty() to test the ‘pdf_doc’ column variable and determine if the value is NULL or not and set the button accordingly. Recall NULL is considered empty and if passed to the empty() function will return TRUE. We first need a connection to the database along with a SELECT query, retrieving all rows from the ‘project_pdf’ table: include __DIR__.'/includes/DatabaseConnection.php'; $query = "SELECT `id`, `project_name`, `pdf_doc` FROM `project_pdf` ORDER BY `project_name` ASC;"; $results = $pdo->query($query); foreach ($results as $row) {     $rows[] = ['id' => $row['id'], 'project_name' => $row['project_name'], 'pdf_doc' => $row['pdf_doc']]; } The next part of the script contains the dynamic PHP, which provides a list of Bootstrap buttons; one for each of the returned records from the MySQL database: PHP foreach loop using empty() function to set button attributes Notice the call to empty() in the button class attribute. Using the PHP ternary operator, each button’s ‘$row[‘pdf_doc’]’ value is checked. The ternary operator uses this syntax:     conditional_test ? truth_result_code : false_result_code If the ‘$row[‘pdf_doc’]’ value is NULL, then empty() returns TRUE. That buttons’ class attribute is set to btn btn-secondary disabled along with the disabled attribute itself. Should the ‘$row[‘pdf_doc’]’ value not be empty() (returns false), then the class attribute is set to btn btn-primary (with no disabled attribute) and stays active. The following screenshots show the active and inactive buttons for each MySQL table row: Button list of all current projects Button in active state. Mouse cursor on Bootstrap inactive button. Notice the ‘Project 3’ button is inactive since its row in the database has a NULL value for the ‘pdf_doc’ column. Be sure and check out these 2 posts on storing and retrieving a .pdf file with PHP and the MySQL BLOB datatype: Use MySQL BLOB column with PHP to store .pdf file PHP MySQL BLOB PDF: Display in Browser I hope through this post, you can find ways to use empty() for similar types of functionality where you see fit. I think it’s pretty neat myself. What creative ways have you used empty()? Tell me about them in the comments below. I’d love to know and learn more uses myself.
