" Experimental investigation of bearing capacity of sand reinforced with rubbers (crumbs tire)"
The topic of my thesis is " Experimental investigation of bearing capacity of sand reinforced with rubbers (crumbs tire)". So, this research is mainly talked about the properties of sand that will be mixed with tire crumbs and how does the crumbs will enhance the properties of the sand. Actually, this sand-rubber mixture will be applied on Boubyan island in Kuwait which is known with its very soft and muddy clay. Five samples will be used in this research which are:
1- Sand with 0% rubber crumbs (sand only)
2- Sand with 10 % rubber crumbs
3- Sand with 20 % rubber crumbs
4- Sand with 30 % rubber crumbs
5- Sand with 40 % rubber crumbs
After I've done the Standard Proctor Compaction test and the Direct Shear Test for the sand and sand-rubber mixture and obtained the properties for each sample, Plaxis 2D software will be used to calculate the settlement and ultimate bearing capacity for all samples and it will helps to know for each sample of sand rubber mixture how much thickness will be needed to make the surface (boubyan clay) stable and not collapse.
Know, to write this thesis I need the writer to write the methodology, results, analysis and discussion, and conclusion. The introduction and background will be written after. If I see what I want in the sections I mentioned I will pay later on for the introduction and literature review.
I attached the file for the main ideas that should be mentions in the thesis the file (thesis) will explain how I wants my thesis flow and what are the main headlines that should be discussed. All the results I got from the experiments tests I done is there in the file. Also, there are some graphs and tables that can help to analyze the results. The paragraphs written in this file should be changed and written in your way because they are all copied from another papers. Its just there to explain for you what I want exactly.
For the compaction test part, the file (past paper) will help you to know how I want you to analyze the results I got from the test. I would like you to add more paragraphs from your own.
For the direct shear test part, the files (past paper) and (Gerard thesis) is helpful. Try to go the same way how Gerard wrote his thesis because I really like his way.
Finally, for the plaxis part the file (plaxis thesis) is the file I want you to follow to write the discussion for the plaxis 2D part. In this file the thesis was about only sand while my thesis is about 5 samples sand and sand-rubber mixture with different ratios of rubber crumbs so do it the same but for my idea the rubber percentage added is a variable. the results for all sample were represented in the excel file attached. While the faiure pattern is selected according to the figure attached in the (failure pattern) folder. The failure pattern is selected according to the plastic point (the red points in the appeared in the figures if they reached the lower layer or no). I will attach a file name (plaxis manual) that will help you to write about how does plaxis work and in page 164 or (5-10) you will find the part of plastic points. Also, as I mentioned above the file (past thesis) will help you to write more for this part.
So now, the thesis will be as follow: (use (thesis) file it attached in the website it’s a word doc)
1- Methodology (not less than 14 pages)

Sample Solution
"Numerous pioneers in struggle circumstances are 'prisoners' to their internal feelings of trepidation and other negative feelings and neglect to see the open doors in settling them" . Indeed, it is a chance if struggle is managed valuably. Administration is a huge and significant subject, yet brimming with befuddling thoughts and wording, open to broadly various translations. It tends to be distinct additionally shift immensely. Instances of authority can be incredibly different as well. We lead when we oversee worker in work place or any association. We lead when we sort out anything. We surely lead when we oversee extends, or build up another business. We can discover administration in each kind of work place, and in each kind of experience and venture, paying little mind to scale, paying little respect to budgetary or official power. Thus, given the numerous manners by which administration works, it is nothing unexpected that initiative is so hard to characterize and portray. As you will see, administration can, fundamentally ought to be drawn closer from an assortment of stances. An accommodating method to comprehend initiative is by investigating administration thinking, type and hypotheses utilizing in certain circumstances as work place clashes and how he deals with the contention in individuals' association. At the point when an individual figures out how to impact the brains of a few people to act with a specific goal in mind towards the satisfaction of a particular or a general objective, at that point that individual is said to have shown initiative characteristics, and is considered as a pioneer. Numerous Africa nations have some association struggle, as a result of the absence of good administration styles still a significant issues. Along these lines, the instance of Mali is specific in this space, similar to others Africa nation. By and large clashes happen when the connection among pioneer and laborers are bad, or if pioneers and individuals are bad. The pioneer provides a feeling of guidance and of direction through the explanation of a convincing perspective. The years either side of the turn of the century saw the procedure of initiative become all the more a social just as a mental procedure of impact. In actuality, more exertion was placed into deciding the idea of the administration forms that were show in hierarchical settings. Maybe, on account of the huge measures of exertion that have been exhausted on revealing the variables related with powerful initiative in associations, there has once in a while been cynicism about the products of this work due to the a wide range of approaches and oftentimes conflicting discoveries (Miner 1975), in spite of the fact that the field is less instilled with a feeling of antagonism these days. Today we can discover numerous sort of initiative Situational possibility, participative, value-based. Explicitly this examination will investigate two hypothetical methodologies (Transactional and Transformational) applied in two gatherings. The principal bunch incorporates Malians pioneers and the subsequent one incorporates Chinese's pioneers. Strife gives off an impression of being an indispensable segment of human working, it has showed in various configurations for centuries. The term could be characterized by a horde of parameters and factors, and this makes trouble in planning an operational and accurate definition. Robbins (1998) accepts that specific shared factors underlie most definitions, and that conventional definitions ought to take a stab at expansive adaptability. He in like manner builds up the accompanying definition: "A procedure that starts when one gathering sees that another gathering has contrarily influenced, or is going to adversely influences something that the principal party thinks about." (1998, p. 434. Dynamic pioneers realize that contention is a characteristic piece of working in gatherings. They learn and practice viable methodologies for overseeing struggle, including approaches to: Manage their very own feelings, address their very own contentions; address others' contentions, practice emphaticness, help exchange, advance intervention. Strife is a characteristic piece of working in gatherings, in light of the fact that various individuals have various thoughts and perspectives. At some point or another, each pioneer should manage a contention between at least two individuals. What is important is the means by which the pioneer and gathering individuals address the contention. Dynamic pioneers realize that contention as a rule doesn't leave without anyone else. It might appear to vanish, yet then it springs up again in a sudden spot or time. To do this examination the analyst was do this system: We depict the exploration questions, speculations, and research plan pertinent to both administration styles and hierarchical peace promotion in some detail further on. The analyst was utilized both quantitative and subjective strategies to give luxuriously elucidating, yet deductively substantial, records of initiative and authoritative peace making forms. Quantitative viewpoints incorporate estimation of initiative styles dependent on poll review style, in utilizing Conflict Management Questionnaire (The Thomas and Kilmann (1974) Conflict Mode Instrument (MODE) and Multifactor Leadership Questionnaire the MLQ, Form 5X-Short (MLQ 5X) (Bass and Avolio 1995).The subjective methodology indicates the impression of laborers in the many work environment circumstances. At that point the analyst was created through substance investigation of information got from perceptions, polls and distributed markers. The approach that the scientist was utilized in this exploration comprises of five stages. Stage one was dedicated to survey of writing and past investigations that have associations with our exploration. The Phase two was dedicated to trial of speculations significant to the connections among administration styles and association peace promotion. At that point the contentions, the causes, the sorts of contention and the various ways to deal with handle struggle have been created. A normal third stage center around the improvement of research instruments, information assortment, information examination and understanding. Stage fourth, was committed to affirm, build up causality, examine and expand past discoveries. The fifth stage was indicated the suggestions for training and for further inquires about.
