A system and method for detecting changes in tire status in real time, e. The embodiments use a slip process analyzer, a skew angle estimator, and a phase noise variance estimator to provide feedforward soft-decision information of a carrier phase recovery for more accurate likelihood calculation based on a high-order hidden Markov model. Each head-slider includes a slider and a magnetic-recording head on the slider for accessing a disk for storing data. A handle is provided in the main body and includes fixed and movable grips. A powder solid that is formed as a result of coagulation of the material powder, and that is included in the molded powder has a diameter shorter than a distance between the electrode and the work. The notches or indented portions are formed in a way that inhibits the formation of additional material portions extending outwardly from the smoothly curved outer surface of the support bar.
