The car business has consistently been a region, where the likelihood to investigate more and to accomplish cutting edge innovation stays a test. As the market is developing, the potential outcomes are being investigated on a more extensive scale. Furthermore, these developing prospects are progressively requesting the exploration for the more exact working of the auto using different sensors and the coordination angles related with them. While improving the quality/execution of the vehicle, the need to diminish the size of sensors consistently stays a test. Throughout the timeframe, the innovation has progressed and these difficulties are taken consideration using MEMS (Micro electro mechanical frameworks) incorporated frameworks. MEMS helps in contriving microscale sensors with higher precision in little size and minimal expense. In the auto, there exists a colossal requirement for these introducing these sensors and using them to refine the exhibition attributes of the vehicles.

Dry Hobbing

Dry hobbing, for friendliness on the environment, for increasing productivity and for decreasing manufacturing cost, often suffers failure of cutting edge of hob or problems about the surface quality of tooth flank of manufactured gear. In the previous report, a simulation method to calculate the clearance between cutting edge of hob and tooth flank of work gear during hobbing process is developed. In this report, this simulation is applied to some practical industrial problems of dry hobbing, i.e. chipping failure of cutting edge of carbide hob and bad coarse scratched surface finish of hobbed tooth flank of manufactured gears, perhaps due to chip crush. The simulation explains the mechanism of such actual failures in detail. On this fact, the “Distance of Single Edge Cutting” of a hob tooth is proposed to be an index of pinching and crushing of chips that could intrude into the clearance between hob cutting edge and tooth flank of work gear. Influencing factors on it are investigated and the bases for finding countermeasures are shown. This method has been applied to some practical cases of problem in mass-production of automotive gears, and good result was confirmed.

Another age of high-recurrence coordinated circuits is displayed, which is called substrate incorporated circuits (SICS). Current cutting edge of circuit plan and implementation stages dependent on this new idea are assessed and dis-cussed in delail. Various potential outcomes and various favorable circumstances of the SICS are appeared for microwave, millimeter-wave and opto hardware applications. Down to earth models are delineated with hypothetical and trial results for substrate coordinated waveguide (SIW), substrate incorporated chunk waveguide (SISW) and substrate incorporated non-transmitting dielectric (SI") direct circuits. Future innovative work patterns are likewise dis-cussed regarding ease imaginative plan of millimeter-wave and optoelectronic coordinated circuits.

The automotive industry was always characterized by innovation and the use of cutting edge technology. Daily we can see vehicles packed with technological advancements. The main focus of the current technological trend is electric drives. With the rise in popularity of electric cars more types of vehicles are adapting electric drives. In the case of airplanes the standards are higher than in the case of cars so the emphasis of research and innovation is greater. This paper presents a list of the challenges electric aircrafts face and their potential solutions. Currently many of these problems currently only have partial solutions if any. There is also a comparison between the properties of materials used and the expectations for hybrid aircraft. A comprehensive model was created taking into account the criteria set for hybrid and electric aircraft. With the aid of the model the effect of the most important components on efficiency can be assessed.

AbstractWhen an environment is uncertain, humans and other animals benefit from preparing for and attempting to predict potential outcomes. People respond to uncertainty both by conserving mental energy on tasks unrelated to the source of the uncertainty and by increasing their attentiveness to information related to the uncertainty. This mental hoarding and foraging allow people to prepare in uncertain situations.

Geometrical Constraints

The output of the ultramicrotomy process with its high strain levels is dependent upon the input, ie., the nature of the material being machined. Apart from the geometrical constraints offered by the rake and clearance faces of the tool, each material is free to deform in whatever manner necessary to satisfy its material structure and interatomic constraints. Noncrystalline materials appear to survive the process undamaged when observed in the TEM. As has been demonstrated however microtomed plastics do in fact suffer damage to the top and bottom surfaces of the section regardless of the sharpness of the cutting edge or the tool material. The energy required to seperate the section from the block is not easily propogated through the section because the material is amorphous in nature and has no preferred crystalline planes upon which defects can move large distances to relieve the applied stress. Thus, the cutting stresses are supported elastically in the internal or bulk and plastically in the surfaces. The elastic strain can be recovered while the plastic strain is not reversible and will remain in the section after cutting is complete.

Light weight materials which possess high strength and durability are being utilized by the automotive industry to increase fuel economy. Rapidly solidified (RS) Al alloys are currently being extensively studied for this purpose. In this investigation the microstructure of an extruded Al-8Fe-2Mo alloy, produced by Pratt & Whitney Aircraft, Goverment Products Div. was examined in a JE0L 2000FX AEM. Both electropolished thin sections, and extraction replicas were examined to characterize this material. The consolidation procedure for producing this material included a 9:1 extrusion at 340°C followed by a 16:1 extrusion at 400°C, utilizing RS powders which have also been characterized utilizing electron microscopy.
