The Implementation of Numbered Head Together (NHT) learning model to Enhance the students Active Role in Learning the Brake System. A thesis of Machine Engginering Education Study Program Faculty of Teacher Training and Educatioon of Sarjanawiyata Tamansiswa University Yogyakarta, 2016.The type of this research is action research including three cycles. Each cycle is conducted by four stages including 1. Planning 2. Implementing 3. Observing and 4. Reflexting. In collecting the Data, the researcher appied test, observation as well as document. The technique used in analyzing the observation sheet and test is quantitive deskriptive.  The result of this research showed that the implementation of Numbered Head Together (NHT) learning model had enhanched both the students learning Active Role and the students’ learning results of the brake system subject to each cycle. It is proved by the increasing result of the observation sheet of the students learning Active Role from which the first cycle 44,57% having increased to the second cycle 16,57% becoming 61,14% and in the third cycle having increased 25,57% becoming 86,71%. Furthermore, based on the learning result test  of the first cycle gave the average grade of the pre test 62,28%, the average grade of the post test then 60,71%, the average grade 69,57% so the learning result increased 8,86% and in the second cycle gave the average grade of pretest 62,28% and the average post test then 75,42% increased the learning result 13,14% and the the test of the third cycle, the average pre test 65,14% and the average post test 83,42%.. Due to the research findings, it can be concluded that the implementation of the Numbered Head Together (NHT) learning model can enhance the students learning Active Role as well as the results of the students learning in the brake system.

An electro-mechanic brake system, which has the potentiality to be used in future cars, has been studied and a prototype of the brake system has been produced. The electro-mechanic brake system has different working principles then hydraulic brake system. Hydraulic force or air pressure is used to obtain the braking force on the wheels in the hydraulic braking systems, whereas a solenoid valve push force is used to stop the car in electro-mechanic systems. A censor controlled the RPM of the wheel and the data was passed to a micro controller and micro controller produced PWM signals according to obtained signal. Thus, push force of the solenoid valve was controlled by micro controlled according to the braking ratio. If the wheel slows down the turning speed, then micro controller stops to sending PWM signals and solenoid is relaxed until wheels turns again. This cycle continues until the all wheels are stopped. A prototype of the system has been constructed and tested. The initial results indicated that the system can be potentially used in the automotives.

Electron microscopy and diffraction of biological materials in the hydrated state requires the construction of a chamber in which the water vapor pressure can be maintained at saturation for a given specimen temperature, while minimally affecting the normal vacuum of the remainder of the microscope column. Initial studies with chambers closed by thin membrane windows showed that at the film thicknesses required for electron diffraction at 100 KV the window failure rate was too high to give a reliable system. A single stage, differentially pumped specimen hydration chamber was constructed, consisting of two apertures (70-100μ), which eliminated the necessity of thin membrane windows. This system was used to obtain electron diffraction and electron microscopy of water droplets and thin water films. However, a period of dehydration occurred during initial pumping of the microscope column. Although rehydration occurred within five minutes, biological materials were irreversibly damaged. Another limitation of this system was that the specimen grid was clamped between the apertures, thus limiting the yield of view to the aperture opening.

In non-UHV microscope environments atomic surface structure has been observed for flat-on for various orientations of Au thin films and edge-on for columns of atoms in small particles. The problem of oxidation of surfaces has only recently been reported from the point of view of high resolution microscopy revealing surface reconstructions for the Ag2O system. A natural extension of these initial oxidation studies is to explore other materials areas which are technologically more significant such as that of Cu2O, which will now be described.

The (110) twin structure of YBa2Cu3O7 superconductor oxide, which is formed to reduce the strain energy of the tetragonal to orthorhombic phase transformation by alternating the a-b crystallographic axis across the boundary, was extensively investigated. Up to now the structure of the twin boundary still remained unclear. In order to gain insight into the nature of the twin boundary in Y-Ba-Cu-O system, a study using electron diffraction techniques including optical and computed diffractograms, as well as high resolution structure imaging techniques with corresponding computer simulation and processing was initiated.Bulk samples of Y-Ba-Cu-O oxide were prepared as described elsewhere. TEM specimens were produced by crushing bulk samples into a fine powder, dispersing the powder in acetone, and suspending the fine particles on a holey carbon grid. The electron microscopy during this study was performed on both a JEOL 2000EX and 2000FX electron microscopes operated at 200 kV.

A statistical review provides analysis of four years of speech therapy services of a suburban school system which can be used for comparison with other school system programs. Included are data on the percentages of the school population enrolled in therapy, the categories of disabilities and the number of children in each category, the sex and grade-level distribution of those in therapy, and shifts in case-load selection. Factors affecting changes in case-load profiles are identified and discussed.
