The finite element (FE) method is a widely used numerical technique for approximating solutions to various problems in different fields such as thermal diffusion, mechanics of continuous media, electromagnetism and multi-physics problems. Recently, there has been growing interest among researchers in the application of fractional derivatives. In this paper, we present a generalization of the FE method known as the conformable finite element method, which is specifically designed to solve conformable fractional partial differential equations (CF-PDE). We introduce the basis functions that are used to approximate the solution of CF-PDE and provide error estimation techniques. Furthermore, we provide an illustrative example to demonstrate the effectiveness of the proposed method. This work serves as a starting point for tackling more complex problems involving fractional derivatives.
In the Principia, Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint for centuries until it was superseded by the theory of relativity. He used his mathematical description of gravity to derive Kepler’s laws of planetary motion, account for tides, the trajectories of comets, the precession of the equinoxes and other phenomena, eradicating doubt about the Solar System’s heliocentricity.[9] Newton solved the two-body problem, and introduced the three-body problem. He demonstrated that the motion of objects on Earth and celestial bodies could be accounted for by the same principles. Newton’s inference that the Earth is an oblate spheroid was later confirmed by the geodetic measurements of Alexis Clairaut, Charles Marie de La Condamine, and others, convincing most European scientists of the superiority of Newtonian mechanics over earlier systems. He was also the first to calculate the age of Earth by experiment, and described a precursor to the modern wind tunnel.
Isaac Newton was born (according to the Julian calendar in use in England at the time) on Christmas Day, 25 December 1642 (NS 4 January 1643[b]) at Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, a hamlet in the county of Lincolnshire.[12] His father, also named Isaac Newton, had died three months before. Born prematurely, Newton was a small child; his mother Hannah Ayscough reportedly said that he could have fit inside a quart mug.[13] When Newton was three, his mother remarried and went to live with her new husband, the Reverend Barnabas Smith, leaving her son in the care of his maternal grandmother, Margery Ayscough (ne Blythe). Newton disliked his stepfather and maintained some enmity towards his mother for marrying him, as revealed by this entry in a list of sins committed up to the age of 19: “Threatening my father and mother Smith to burn them and the house over them.”[14] Newton’s mother had three children (Mary, Benjamin, and Hannah) from her second marriage.[15]
From the age of about twelve until he was seventeen, Newton was educated at The King’s School in Grantham, which taught Latin and Ancient Greek and probably imparted a significant foundation of mathematics.[16] He was removed from school by his mother and returned to Woolsthorpe-by-Colsterworth by October 1659. His mother, widowed for the second time, attempted to make him a farmer, an occupation he hated.[17] Henry Stokes, master at The King’s School, and Reverend William Ayscough (Newton’s Uncle) persuaded his mother to send him back to school.[18] Motivated partly by a desire for revenge against a schoolyard bully, he became the top-ranked student,[19] distinguishing himself mainly by building sundials and models of windmills.[20]
In June 1661, Newton was admitted to Trinity College at the University of Cambridge. His uncle the Reverend William Ayscough, who had studied at Cambridge, recommended him to the university. At Cambridge, Newton started as a subsizar, paying his way by performing valet duties until he was awarded a scholarship in 1664, which covered his university costs for four more years until the completion of his MA.[21] At the time, Cambridge’s teachings were based on those of Aristotle, whom Newton read along with then more modern philosophers, including Ren Descartes and astronomers such as Galileo Galilei and Thomas Street. He set down in his notebook a series of “Quaestiones” about mechanical philosophy as he found it. In 1665, he discovered the generalised binomial theorem and began to develop a mathematical theory that later became calculus. Soon after Newton obtained his BA degree at Cambridge in August 1665, the university temporarily closed as a precaution against the Great Plague.[22]
Although he had been undistinguished as a Cambridge student, his private studies and the years following his bachelor’s degree have been described as “the richest and most productive ever experienced by a scientist”.[23] The next two years alone saw the development of theories on calculus,[24] optics, and the law of gravitation, at his home in Woolsthorpe. The physicist Louis Trenchard More suggesting that “There are no other examples of achievement in the history of science to compare with that of Newton during those two golden years.”[25]
Newton has been described as an “exceptionally organized” person when it came to note-taking, further dog-earing pages he saw as important. Furthermore, Newton’s “indexes look like present-day indexes: They are alphabetical, by topic.” His books showed his interests to be wide-ranging, with Newton himself described as a “Janusian thinker, someone who could mix and combine seemingly disparate fields to stimulate creative breakthroughs.”[26]
In April 1667, Newton returned to the University of Cambridge, and in October he was elected as a fellow of Trinity.[27][28] Fellows were required to take holy orders and be ordained as Anglican priests, although this was not enforced in the Restoration years, and an assertion of conformity to the Church of England was sufficient. He made the commitment that “I will either set Theology as the object of my studies and will take holy orders when the time prescribed by these statutes [7 years] arrives, or I will resign from the college.”[29] Up until this point he had not thought much about religion and had twice signed his agreement to the Thirty-nine Articles, the basis of Church of England doctrine. By 1675 the issue could not be avoided, and his unconventional views stood in the way.[30]
His academic work impressed the Lucasian Professor Isaac Barrow, who was anxious to develop his own religious and administrative potential (he became master of Trinity College two years later); in 1669, Newton succeeded him, only one year after receiving his MA. Newton argued that this should exempt him from the ordination requirement, and King Charles II, whose permission was needed, accepted this argument; thus, a conflict between Newton’s religious views and Anglican orthodoxy was averted.[31] He was appointed at the age of 26.[32]
As accomplished as Newton was as a theoretician he was less effective as a teacher as his classes were almost always empty. Humphrey Newton, his sizar (assistant), noted that Newton would arrive on time and, if the room was empty, he would reduce his lecture time in half from 30 to 15 minutes, talk to the walls, then retreat to his experiments, thus fulfilling his contractual obligations. For his part Newton enjoyed neither teaching nor students. Over his career he was only assigned three students to tutor and none were noteworthy.[33]
The Lucasian Professor of Mathematics at Cambridge position included the responsibility of instructing geography.[34] In 1672, and again in 1681, Newton published a revised, corrected, and amended edition of the Geographia Generalis, a geography textbook first published in 1650 by the then-deceased Bernhardus Varenius.(Bernhardus Varenius, Geographia Generalis, ed. Isaac Newton, 2nd ed. (Cambridge: Joann. Hayes, 1681))[35][36] In the Geographia Generalis, Varenius attempted to create a theoretical foundation linking scientific principles to classical concepts in geography, and considered geography to be a mix between science and pure mathematics applied to quantifying features of the Earth.[34][37] While it is unclear if Newton ever lectured in geography, the 1733 Dugdale and Shaw English translation of the book stated Newton published the book to be read by students while he lectured on the subject.[34] The Geographia Generalis is viewed by some as the dividing line between ancient and modern traditions in the history of geography, and Newton’s involvement in the subsequent editions is thought to be a large part of the reason for this enduring legacy.[38] cc7c31b456

My very important budget-file is corrupted! I use Excel for Mac 2008 on my Macbook (Mac OS X 10.6.8). I recently used the file but now when I want to open it it says ‘The file you are trying to open is possibly read-only or the location you are trying to open is read-only. Or the server you are trying to access is not responding’.
I tried all of these recommendations to no avail. I even went as far as to buy a file repair application (it just crashed repeated). In the end I found that I could open my Excel file in Numbers! I then exported from Numbers back to Excel and voila! Problem solved!
I followed the suggestion to send the file to a Windows system. Then I changed the extension .xlsx to .xls on Explorer, and proceeded to open the file on Excel. I byassed any warnings to proceed as such, and Excel was able to open the file. I then saved the file as .xlsx, and sent it back to the Mac system.
let them do the open and repair ( open black excel file / file / open / choose file / choose open and repair (there is open button and and arrow , click the arrow to show open and repair button ) / the file will open / save it / let him send it back to your email / open it on your mac and its solved
I have experienced the same problem and was wondering if any software can help me fix the issue. I could not find any software that can repair Excel file on the Mac so I copied the file on Windows and tried demo version of a software. That works up to an extent, but could not recover the formatting.
This is an excellent tip, and saved me several hours of rework. I had a largish file with some tangly formulas with indirect, dcount/dstdev, averageif, and some array formulas and it stopped opening. Excel would crash with a EXCBADACCESS every time, on multiple machines and the most recent backup that would open meant losing several hours work. After opening it with auto-calculation turned off and saving it and turning auto-calc back on, it stopped crashing Excel on open.
3. Click on the small drop-down arrow at the right side of the “Open” button. Choose the “Open and Repair” option. Choose “Repair” to have Excel attempt to recover the damaged file. Choose “Extract data” to extract the information in the spreadsheet to another file.
6. Choose the “All files and folders” option and type “.xls” in the search box. This will find all Excel spreadsheets on your computer, whether they were created in Excel 2007 or an earlier version. Click “OK” to start the search.
Marifilps364, the instructions you provided are for the Windows version of Excel running on Microsoft Windows. The software you linked to is for Windows only. Useful information but not applicable to Macs.
Finally! I tried repairing Disk permissions in Diskutility.app. I tried turning off auto calculations in Excel. I tried saving as a new file format. I tried opening read only. I downloaded Stellar Phoenix excel repair – it seems to be doing something but it literally does one cell at a time and takes about 3-5 seconds per CELL. I had 23 tabs with a lot of data. Maybe by Christmas I can open it. I even went to a site linked here on the Apple support site that was an online repair solution but when it wasn’t clear it was a legit company and when I read the legal terms and it said I am willing to abide by the laws of Russia… I didn’t trust sending my confidential doc out to that hosted service. Who knows…
So it is ironic that Numbers is the fix. Now it didn’t import my conditional formatting and I see some key formulas that aren’t working now (value was pasted in), but overall it seems to be successful. Thanks!!
The presence of Microsoft Excel is not required. Previewing of XLSX files is performed from Recovery Toolbox for Excel directly. Of course, it limits visualization capabilities, for example, it does not execute macros. The registered version removes all limitations and allows to save recovered data into a new XLSX file.

The tool can work as a viewer for XLSX files, even if you don’t have Excel or Office installed. The tool allows you to open and view any XLSX files for an unlimited number of times.
There is a full preview of Excel spreadsheets in Recovery Toolbox for Excel, and it’s similar to how it is implemented in Microsoft Office. The tool opens XLSX files for viewing, even if they are damaged. Plus, it’s free for an unlimited number of times.
You can use the last backup or restore to the previous stable copy of the file, or try to use Recovery Toolbox for Excel to restore damaged Excel spreadsheets. With a very high probability, Recovery Toolbox for Excel can return data .xlsx files to their original state before they were damaged. To verify this statement, it is necessary to:
If you need to fix the corrupted Excel file, then the full version of Recovery Toolbox for Excel will allow you to do this in a few simple steps. The fixing of Excel files occurs by copying the corrected data from the damaged .xlsx file to a new Excel project. The tool does not fix or modify the existing XLSX file. All recovered data is transferred to a new Excel spreadsheet. Corrected data from a damaged XLSX file can be exported to a new Excel spreadsheet or a new XLSX file.
Recovery Toolbox is constantly conducting a large study of the quality of recovery of corrupt XLSX files and Microsoft Excel XLS files. A huge array of real corrupted user files, which are uploaded by real users to the online cloud service , was used as a base for research and comparison. Such comparative testing is regularly done to improve the quality of data recovery. This helps to improve the quality of recovery of corrupted Excel files.
The testing was done on 1000+ real corrupted user XLSX files and XLS files using different utilities and services. The files were not selected somehow specially, there was no additional sampling, no selection of source files for the test.
The program will read and analyze a corrupted Microsoft Excel file for several minutes. After recovering data from an Excel file, you can see a grid with a recovered cell from an Excel spreadsheet. Please press the Start recovery button to directly export recovered data into a new Microsoft Excel file or new Microsoft Excel workbook.
On this step you will see a message saying: Do you wish to start recovery? To start the recovery, click Yes. The program will start scanning the damaged files and recovering the information.
After the scanning is complete, the program shows all the information it could extract. The data is shown as a table and looks like a Microsoft Excel worksheet, but the font in the cells is unformatted. The worksheet contains information from the source file, but the formatting isn’t preserved. The user can scroll large workbooks vertically or horizontally and switch between worksheets.
Viewing the recovered information helps the user to make sure that the correct worksheet was recovered. It also shows the capability of Recovery Toolbox for Excel and proves that the program can recover the possible maximum amount of data.
To export the recovered information to Microsoft Excel, click the Start Recovery button. This launches Microsoft Excel and a new file is created where the data will be exported. The worksheet cells will have the same formatting (cell size, fonts, etc.) as the source file had. After the recovered data is exported, the user can work with it or save the information to another file.
The tool has a demo version that can view XLSX file contents before repairing. However, in many cases, this might not be enough if you need to open a damaged XLSX file and work with the data. To do this, you will need an online license that gives you full access to Recovery Toolbox for Excel, which you can find on this page.
