“…As identified in the introduction, the mechanism of hot spotting is still not fully understood. The theoretical debates mainly concentrated on the trigger conditions of hot spots (critical speed versus energy input), 4,5,9,10 the effects of the brake disc structural characteristics (vents, pins, solid brake discs or ventilated brake discs), 1,16,17 the initial brake disc waviness 15 and the brake pad length. 7,8,18,19 Therefore, in order to investigate the effects of the determinants on hot spotting, a parametric study was performed on the basis of the 3D model presented in the fourth section.…”

“…Moreover, there are some other possible determinants of hot spotting. Suryatama et al 15 constructed a three-dimensional (3D) thermomechanical contact model with variation in the initial thickness of the brake disc, and the high-temperature zones were found to be localised at the peaks of the surface ripples of the brake disc.…”

The idea of making Taruna Nusantara High School was sparked by the Minister of Defense and Security General LB Moerdani on May 20, 1985 at the Great Pavilion of Taman Siswa Yogyakarta. He has a vision to build a school that educates the best people from all over Indonesia and produces graduates who can continue the aspirations of the proclamator. This idea was continued by signing a Memorandum of Understanding between the Indonesia Arm Force with and Taman Siswa, which was the first educational organization in Indonesia, the Foundation of Indonesia Arm Force. The purpose of this study is to determine the factors to determine the factors that influence the competitiveness of both external factors and internal factors and find out the right strategy to increase competitiveness based on the SWOT analysis approach and AHP data processing tools. Data collection techniques were obtained by interview, observation and documentation. The Results of this study are based on those conducted by expert Respondents on the factors that influence in increasing competitiveness in the Taruna Archipelago High School in Magelang. External Factors (Competitions from similar schools, students who fail selection at TN High School Gaining the trust of parents of students and the wider community for the next career path, the existence of student sanctions). The right strategy and is used based on SWOT Analysis from the results of interviews with the expert team is to choose the strategy of Strength and Opportunity in terms of the application of quality and service in educational institutions (both in terms of Sarpras and HR).

“…Unlike cold judder, hot judder does not require large amplitude permanent disk irregularities for its initialization. When exposed to braking pressure, permanent irregularities (both with low and high amplitudes) cause a localized rise in the contact pressure field and temperature, leading to hot spot generation [5,6,7]. The hot spots result in instantaneous DTV and spatial friction variation, causing brake pressure and brake torque pulsations during braking.…”

A novel method for attenuation of brake judder directly at the source is proposed, utilizing an electromechanical brake to actively compensate for the variation in brake torque that causes judder. Taking advantage of the high-bandwidth closed-loop clamp force tracking performance offered by an electromechanical brake, an adaptive compensator is designed to estimate the brake torque variation (BTV), and to produce a compensating clamp force command to cancel it. The compensator is tested over fixed and varying BTV frequencies by employing a production-ready prototype EMB. It is demonstrated that significant BTV attenuation is obtained using the proposed approach.
