A Matrix Model for Type 0 Strings [PDF]
, 1999 A matrix model for type 0 strings is proposed. It consists in making a non-supersymmetric orbifold projection in the Yang-Mills theory and identifying the infrared configurations of the system at infinite coupling with strings.

Enhancing passenger-bus crashworthiness through frontal structural reinforcement
Transportation EngineeringPassenger buses are highly vulnerable to frontal collisions, which account for a significant proportion of severe accidents. This study addresses this issue by redesigning the frontal structure of buses to comply with UNECE R29 (Rev.2) crashworthiness ...

Dilaton Dynamics from Production of Tensionless Membranes [PDF]
, 2006 In this paper we consider classical and quantum corrections to cosmological solutions of 11D SUGRA coming from dynamics of membrane states. We first consider the supermembrane spectrum following the approach of Russo and Tseytlin for consistent ...

Frontal impact on bus superstructure as per UNECE R29 and NCAP
IOP Conference Series: Materials Science and Engineering, 2019 Abstract Frontal crash for the large vehicle is less severe compared to the lightweight vehicle due to the height position of the driver compartment in the vehicle which sits well above the impact area in any accident involving a passenger vehicle. Due to this reason, most of the coachbuilder does not include crumple zone in their design

Duality and Light Cone Symmetries of the Equations of Motion
, 1998 The matrix theory description of the discrete light cone quantization of $M$ theory on a $T^{2}$ is studied. In terms of its super Yang- Mills description, we identify symmetries of the equations of motion corresponding to independent rescalings of one ...
