Abstract The crash-worthiness design of civil transport aircraft fuel systems is significance to improve the safety in case a crash. CCAR25.993 (f) requires that “fuel feed line fuselage shall be assembled allow reasonable deformation and tension without leakage”. Fuel system supply with appropriate hose configuration can take advantage ductility material, guillotine test accepted by worldwide ...

in order to help in the engineering design of rice harvesting machines, there is a need to have exact information concerning the physical and mechanical properties of rice stems. the cutting force for rice stems, therefore, was measured by designing and fabricating a static and dynamic shear test apparatus. the effects of moisture levels and the cross-sectional area of stem as well as the varie...

In this paper we propose a system to solve a language game, called Guillotine, which requires a player with a strong cultural and linguistic background knowledge. The player observes a set of five words, generally unrelated to each other, and in one minute she has to provide a sixth word, semantically connected to the others. Several knowledge sources, such as a dictionary and a set of proverbs...

In the laser cutting process some well-known parameters, e.g. laser power and cutting speed, play major roles in the performance of the process. Each parameter or a combination of parameters can affect the material removal volume and cutting volume efficiency. The purpose of this research is to study the effect of power and maximum cutting speed on the material removal rate (MRR) and cutting vo...

andré chénier (1762-1794) is the greatest and the best known french poet of the 18th century. he is famous especially for his courageous opposition to the power of the terror in the early years of the french revolution which caused finally his death by guillotine. the study of his poetical works can clarify the literary transition between neoclassicism and romanticism. this paper, by describing...

vibration cutting (vc), elliptical vibration cutting (evc) and ordinary cutting (oc) of in738 work-pieces have been experimentally investigated in the present research. the experiments were carried out by using single crystal diamond tool and ultra-precision cnc lathe. vibration frequency is 36.16khz and the amplitude is . the influence of various cutting parameters including cutting speed, fee...

crops and agricultural products are subject to natural loading during growth. different mechanical forces are also exerted on them during harvest. one product, sugar cane, experiences large shear forces are during harvest. an examination of the crop properties and machine parameters of sugar cane are necessary to develop appropriate cutting tools and the optimization and design of harvesting ma...
