On August 5, 2012, the Mars Science Laboratory entry vehicle successfully entered Mars atmosphere, flying a guided entry until parachute deploy. The Curiosity rover landed safely in Gale crater upon completion of the Entry Descent and Landing sequence. This paper compares the aerodynamics of the entry capsule extracted from onboard flight data, including Inertial Measurement Unit (IMU) accelerometer and rate gyro information, and heatshield surface pressure measurements. From the onboard data, static force and moment data has been extracted. This data is compared to preflight predictions. The information collected by MSL represents the most complete set of information collected during Mars entry to date. It allows the separation of aerodynamic performance from atmospheric conditions. The comparisons show the MSL aerodynamic characteristics have been identified and resolved to an accuracy better than the aerodynamic database uncertainties used in preflight simulations. A number of small anomalies have been identified and are discussed. This data will help revise aerodynamic databases for future missions and will guide computational fluid dynamics (CFD) development to improved prediction codes.

A railway management system is an automatic system that is used in the railways to improve efficiency. Earlier, manual systems were used in railways; this made it difficult to exchange information from the train to the ground, causing a delay in displaying information for passengers. In this era of hyper-urbanization, people want a faster and more convenient mode of transportation. Therefore, the rapid economic and demographic growth across the world is driving the growth of the Global Railway Management System market. In addition, technological advancement is another factor that is propelling the growth of railway infrastructures. Since the Railway industry is one of the major contributors to the economic growth of a country, there is an inherent need for an efficient management system. In this regard, advanced technology will help the railways to upgrade their management and operational systems.

The fuel used by ships and boats is varied and ranges from diesel and gasoline to just wind energy. For instance, ships that carry cargos and containers mainly run on diesel; however, gasoline and sails are also commonly used. With fuel prices increasing exponentially, the demand for alternative energy sources to propel ships and boats is greater than ever. Electricity and solar energy are cheaper than diesel and gasoline, and small ships and boats are now using these alternative sources of energy. Boats that are primarily powered by electric energy are known as electric boats.
