I n 1961, Bernard Fall, a scholar and practitioner of war, published a book entitled The Street Without Joy. The book provided a lucid account of why the French Expeditionary Corps failed to defeat the Viet Minh during the Indochina War, and the book’s title derived from the French soldiers’sardonic moniker for Highway 1 on the coast of Indochina—“Ambush Alley,” or the “Street without Joy.” In ...

In this age of modern era, the use of internet must be maximized. Yeah, internet will help us very much not only for important thing but also for daily activities. Many people now, from any level can use internet. The sources of internet connection can also be enjoyed in many places. As one of the benefits is to get the on-line the shadow war the third reich book, as the world window, as many p...

The term asymmetric war is a product of the revolution in military affairs (RMA). It can be taken as fresh jargon to distinguish the modern variant from traditional partisan and guerrilla war conducted by irregular bands using unconventional methods. In short, it is nothing new; only the cosmopolitan veneer is so. Since the Indian Army has vast experience dating to the preindependence period in...

Gears are an integral and necessary component in our everyday lives. Most of the work performed in plastic and metal but very few works available in combine effect of plastic and metal gears. The main problem while referring plastic gear is the bending strength and in case of metal gear is cost. Hence, the work is performed on metal plastic composite gear to get benefit of both. Here use the co...

Epicyclic gears are used in many applications because they can achieve a large torque/speed ratio in a compact package. In most gearboxes, the estimated spectrum of the vibration signal is symmetric and centered at the meshing frequency. For epicyclic gears, the estimated spectrum is typically asymmetric and the dominant frequency component does not occur at the meshing frequency. This is an im...

I examined two contexts of development in children’s problem solving: (1) the macro-context of different age cohorts (8-9 vs 11-12 years of age): and (2) the micro-context of an approximately one-hour experimental session. Twenty subjects (even divided across sexes and these two age groups) were individually presented o collection of variously sized gears, o board onto which these gears could b...

This paper presents the investigation into the tooth profile features, meshing characteristics and the principle of forming circular arc tooth race cylindrical gears (CATT gears). Based on the meshing theory of the curvilinear gear, tooth surface equations and meshing line equations of the gears and rack shave been established. The graphical analysis of these equations shows meshing performance...

Gear shaping is the most important process for manufacturing internal gears. Even if this method also suitable production of spur gears, these can be produced more effectively using hobbing. interesting face-gears. Since shaper cutter quite simple compared to a hob and tool costs are therefore relatively low, particularly small series production. This manuscript deals with simulation gear face-...
