Investigation of pitting - like operating defects

This report details my work at the endpoint of the internship I spent within the Composite Manufacturing Unit of Airbus Defence & Space in Les Mureaux, France. It is as well the conclusion of the master’s program in aerospace engineering that I attended at KTH Royal Institute of Technology, Sweden.This document gives an overview of the cost reduction key drivers within a small batch aerospace manufacturing line. Some of the suggested leads developed in the paper have been set up in the past on the composite production lines and are proving their value. Some others are currently being deployed within the scope of a large cost reduction program called "Cap Composite". Finally some of them are my own responsibility since I have been in charge of developing them or taking them a few steps further.The internship took place within the ULR (ultra-light reflector) manufacturing line. As mentioned in the problematic, it is a small batch manufacturing line and most of the mentioned points of the report are applied on it.On the one hand, cost reduction drivers have been investigated to finally come up with a few guidelines to efficiently organize the production. The importance of management, the benefits of smart design and industrialization of the products, but also the workshop-oriented lean approach will be explained.On the other hand, the second part of the report will propose extended information about my missions within the manufacturing unit and the results that were engendered. I will also give my personal opinion and feedback about my different assignments and more generally my internship

The Right of Publicity and the First Amendment in the Modern Age of Commercial Speech

The so-called right of publicity gives individuals a legally protected interest against commercially motivated communicators’ use of their names or likenesses for purposes of commercial gain. Although the right is sometimes viewed as a subcategory of the right of privacy, it may be exercised by the best known celebrities, as well as by the most private individual. It is therefore more properly characterized as a property interest in one’s name and likeness than a protection of one’s privacy. In order to satisfy the concerns of the First Amendment right of free expression, however, the statutory and common law development of the right has always been qualified by a “public interest” exception: the right does not extend to the commercial use of an individual’s name or likeness when either is employed as part of a communication that furthers the public’s interest in acquiring information. This public interest exception, however, has never been applied to the communication of a profit-motivated speaker when the name or likeness is used as part of the commercial promotion of the sale of a product or service. It has long been assumed that such communications are merely commercial advertising, that inherently lack the public importance of expression by the more traditionally protected communications media. This assumption has been made despite the fact that the commercial advertiser may be communicating the exact same information about a celebrity that was given First Amendment like protection when disseminated by the equally commercially motivated media. Although at the time these assumptions were made they were consistent with controlling First Amendment theory and doctrine, courts enforcing the right of publicity appear to have been operating in a time warp over the last thirty years, ignoring all but completely the evolution of a vigorous First Amendment protection of commercial speech. Application of currently accepted doctrinal precepts of commercial speech protection reveal that discrimination against commercial advertisers in invocation of the public interest exception is unambiguously unconstitutional. The only conceivable reason to discriminate against commercial advertisers when they communicate the exact same information about celebrities that is fully protected when disseminated by the commercially motivated communications media is the narrow profit motivation of the advertiser. This, however, is a constitutionally unacceptable basis for distinction; in no other area of First Amendment jurisprudence is a speaker disqualified because of his or her narrow self-interest—even when that interest is purely economic, as in the case of the commercial advertiser. This Article argues that the courts’ willingness to incorporate established precepts of commercial speech protection into their right of publicity calculus is long overdue

Беззахисне національне багатство України, як результат реформування державних органів (Defenceless national wealth of Ukraine, as a result the public authorities' reforming)

Дана стаття присвячена питанням реформування системи органів, що мають повноваження у сфері охорони земельних ресурсів та змінам, які відбулися в їх повноваженнях. (In the process of the state development as a result of changes that take place in public relations, there may be a need for reforms and adjustment of the activity of state bodies, as a result of which the system and powers of state bodies may change. This article deals with the issues of reforming the system of bodies with powers in the field of land resources protection and the changes that took place within the powers of these bodies. The changes that took place in the system of governing bodies and law enforcement bodies and the impact of these changes on the protection of land resources are considered. The chronology of transformations of the specially authorized body on land resources has been specifi ed and an analysis of the changes that took place in the authority and subordination has been made. It was Compared the powers of militia and police in the field of land resources protection. The impact of the new Law «On the Prosecutor's Office» on the powers of the prosecutor's offices in the field of land protection is analyzed. It is concluded that the most of changes in the system of state bodies that have powers in the field of land protection have led to the abolition or simplifi cation of a number of powers of these bodies or, in general, to the elimination of certain bodies, which may adversely affect the protection of land resources.

Transportation research process bulk material widely universal screw conveyor

Наведено конструкцію широкоуніверсального шнекового транспортера з різними технологічними можливостями. Встановлено, що важливою умовою при виборі конвеєрів для універсальних перевантажувальних комплексів є визначення області їх використання, зокрема щодо транспортування певного діапазону сипких вантажів. Оскільки мінімальна межа енергоємності гвинтових конвеєрів визначається коефіцієнтом тертя вантажу до поверхні спіралі, то визначальною умовою при проектуванні конвеєра є його спроможність транспортувати вантаж з несприятливими властивостями. При цьому розглянуто найнесприятливіше, з точки зору енергетичних затрат вертикальне розміщення гвинтового конвеєра. Виведено аналітичні залежності для визначення силових, конструктивних і кінематичних параметрів. Отримані співвідношення дозволяють з високою точністю обчислити оптимальні конструктивні й технологічні параметри гвинтових конвеєрів (ГК), при яких забезпечується потрібна якість суміші при високій ефективності процесу транспортування.Screw transporter has been developed, which consists of the vertical tube-column, to which the horizontal loading branch is fixed rigidly in the upper part being able to revolve, and in the bottom part – the unloading branch is fixed. Loading and unloading branches are similar in design and are separate units with the separate electric drives located horizontally. Screw shafts are fixed rigidly to the ends of the electric drives shafts and inserted into the tubes. The other ends of the shaft are inserted into the tube ends piers. The second end of the tube of loading and unloading branches is limited by the stopper, with the help of which they are fastened to the tube-stoppers of the upper and bottom branches, which in their turn are fixed to the electric drives stoppers by the second end. Tube-stoppers of the upper and bottom branches can revolve. In the upper part of the tube-stopper of the unloading branch a cylinder hole is made to supply the bulk-cargo from the top downwards. Besides, the loading and unloading branches are equipped with the stopper mechanisms, one of which is located in the upper part of the tube on the loading branch, and in the bottom, in the lower part of the unloading branch. Stopper mechanisms are made as step-by-step cylinder rollers, which are fixed rigidly to the stoppers and stopping bushes welded to the tube-column. Stopper mechanisms are fixed rigidly to the tie links, which are mounted through the bushes by the stoppers to the vertical tube-base, which is fixed to the frame. The supply of the bulk-cargo from the heap is performed by the left end of the loading branch. The unloading of the bulk-cargo in the unloading branch 3 is performed by the screw 6 through the exit into the tank. The upper loading branch is mounted on the tube-column, the angle of its inclination to the horizon being adjusted by the known-design mechanism. The bottom branch is mounted at the inclination angle to the horizon. Besides, the screws of both branches are rigidly fixed to the shafts with uniformly increased steps along the length of the upper branch towards the supply of the bulk-cargo in the place of the tube-column hole, and the bottom branch towards the exit of the bulk-cargo from the transporter
