Pengaruh Motivasi dalam Pembelajaran

That the learning outcomes is an overview of the progress or development of students from the first to follow the educational program until the time they ended the educational program which he passes. So the study results can be seen after learners gain experience learning and behavioral changes. So with a change in the student after a learning experience and that's called learning outcomes. Someone students who have high motivation to learn, have the drive or desire to learn a subject, students who have the desire and drive to learn a subject guided by their needs. One needs are close to success in learning a subject is need for achievement. That students who have high motivation to learn, will be marked with a bold desire to compete and receive feedback and encouragement to always be responsible and goal attainment. That students who have the drive to take responsibility and achievement of learning objectives, makes the learners to always be disciplined and focused in learning a subject. Therefore, students who have high motivation to learn, will get better learning outcomes compared to students with low learning motivation. Thus, if in improving learning outcomes of a subject, the need for efforts to increase student motivation. Motivation is realized in the form of action, is one factor that can be used to predict the progress of learning

A 16 channel high-voltage driver with 14 bit resolution for driving piezoelectric actuators

A high-voltage, 16 channel driver with a maximum voltage of 72 volt and 14 bit resolution in a high-voltage CMOS (HV-CMOS) process is presented. This design incorporates a 14 bit monotonic by design DAC together with a high-voltage complementary class AB output stage for each channel. All 16 channels are used for driving a piezoelectric actuator within the control loop of a micropositioning system. Since the output voltages are static most of the time, a class AB amplifier is used, implementing voltage feedback to achieve 14 bit accuracy. The output driver consists of a push-pull stage with a built-in output current limitation and high-impedance mode. Also a protection circuit is added which limits the internal current when the output voltage saturates against the high-voltage rail. The 14 bit resolution of each channel is generated with a segmented resistor string DAC which assures monotonic by design behavior by using leapfrogging of the buffers used between segments. A diagonal shuffle layout is used for the resistor strings leading to cancellation of first order process gradients. The dense integration of 16 channels with high peak currents results in crosstalk, countered in this design by using staggered switching and resampling of the output voltages

SEIS: Insight's Seismic Experiment for Internal Structure of Mars.

By the end of 2018, 42 years after the landing of the two Viking seismometers on Mars, InSight will deploy onto Mars' surface the SEIS (Seismic Experiment for Internal Structure) instrument; a six-axes seismometer equipped with both a long-period three-axes Very Broad Band (VBB) instrument and a three-axes short-period (SP) instrument. These six sensors will cover a broad range of the seismic bandwidth, from 0.01 Hz to 50 Hz, with possible extension to longer periods. Data will be transmitted in the form of three continuous VBB components at 2 sample per second (sps), an estimation of the short period energy content from the SP at 1 sps and a continuous compound VBB/SP vertical axis at 10 sps. The continuous streams will be augmented by requested event data with sample rates from 20 to 100 sps. SEIS will improve upon the existing resolution of Viking's Mars seismic monitoring by a factor of ∼ 2500 at 1 Hz and ∼ 200 000 at 0.1 Hz. An additional major improvement is that, contrary to Viking, the seismometers will be deployed via a robotic arm directly onto Mars' surface and will be protected against temperature and wind by highly efficient thermal and wind shielding. Based on existing knowledge of Mars, it is reasonable to infer a moment magnitude detection threshold of M w ∼ 3 at 40 ∘ epicentral distance and a potential to detect several tens of quakes and about five impacts per year. In this paper, we first describe the science goals of the experiment and the rationale used to define its requirements. We then provide a detailed description of the hardware, from the sensors to the deployment system and associated performance, including transfer functions of the seismic sensors and temperature sensors. We conclude by describing the experiment ground segment, including data processing services, outreach and education networks and provide a description of the format to be used for future data distribution.Electronic supplementary materialThe online version of this article (10.1007/s11214-018-0574-6) contains supplementary material, which is available to authorized users

Silicon-germanium BiCMOS device and circuit design for extreme environment applications

Silicon-germanium (SiGe) BiCMOS technology platforms have proven invaluable for implementing a wide variety of digital, RF, and mixed-signal applications in extreme environments such as space, where maintaining high levels of performance in the presence of low temperatures and background radiation is paramount. This work will focus on the investigation of the total-dose radiation tolerance of a third generation complementary SiGe:C BiCMOS technology platform. Tolerance will be quantified under proton and X-ray radiation sources for both the npn and pnp HBT, as well as for an operational amplifier built with these devices. Furthermore, a technique known as junction isolation radiation hardening will be proposed and tested with the goal of improving the SEE sensitivity of the npn in this platform by reducing the charge collected by the subcollector in the event of a direct ion strike. To the author's knowledge, this work presents the first design and measurement results for this form of RHBD.M.S.Committee Chair: Cressler, John; Committee Member: Papapolymerou, John; Committee Member: Ralph, Stephe

Optimising the multiplex factor of the frequency domain multiplexed readout of the TES-based microcalorimeter imaging array for the X-IFU instrument on the Athena Xray observatory

Athena is a space-based X-ray observatory intended for exploration of the hot and energetic universe. One of the science instruments on Athena will be the X-ray Integrated Field Unit (X-IFU), which is a cryogenic X-ray spectrometer, based on a large cryogenic imaging array of Transition Edge Sensors (TES) based microcalorimeters operating at a temperature of 100mK. The imaging array consists of 3800 pixels providing 2.5 eV spectral resolution, and covers a field of view with a diameter of of 5 arc minutes. Multiplexed readout of the cryogenic microcalorimeter array is essential to comply with the cooling power and complexity constraints on a space craft. Frequency domain multiplexing has been under development for the readout of TES-based detectors for this purpose, not only for the X-IFU detector arrays but also for TES-based bolometer arrays for the Safari instrument of the Japanese SPICA observatory. This paper discusses the design considerations which are applicable to optimise the multiplex factor within the boundary conditions as set by the space craft. More specifically, the interplay between the science requirements such as pixel dynamic range, pixel speed, and cross talk, and the space craft requirements such as the power dissipation budget, available bandwidth, and electromagnetic compatibility will be discussed

Space Structures: Issues in Dynamics and Control

A selective technical overview is presented on the vibration and control of large space structures, the analysis, design, and construction of which will require major technical contributions from the civil/structural, mechanical, and extended engineering communities. The immediacy of the U.S. space station makes the particular emphasis placed on large space structures and their control appropriate. The space station is but one part of the space program, and includes the lunar base, which the space station is to service. This paper attempts to summarize some of the key technical issues and hence provide a starting point for further involvement. The first half of this paper provides an introduction and overview of large space structures and their dynamics; the latter half discusses structural control, including control‐system design and nonlinearities. A crucial aspect of the large space structures problem is that dynamics and control must be considered simultaneously; the problems cannot be addressed individually and coupled as an afterthought
