"Compensating for quasi-periodic motion in robotic radiosurgery outlines the techniques needed to accurately track and compensate for respiratory and pulsatory motion during robotic radiosurgery. The algorithms presented within the book aid in the treatment of tumors that move during respiration.
In Chapters 1 and 2, the book introduces the concept of stereotactic body radiation therapy, motion compensation strategies and the clinical state-of-the-art. In Chapters 3 through 5, the author describes and evaluates new methods for motion prediction, for correlating external motion to internal organ motion, and for the evaluation of these algorithms’ output based on an unprecedented amount of real clinical data. Finally, Chapter 6 provides a brief introduction into currently investigated, open questions and further fields of research. "

"Penggunaan lengan robot dapat menggantikan ataupun meringankan kerja manusia secara langsung. Namun terdapat kendala yaitu sistem user interface lengan robot yang rumit. Oleh karena itu dibutuhkan user interface lengan robot yang intuitif untuk dipelajari dan mudah untuk dioperasikan. Pada penelitian ini dirancang dan diimplementasikan sebuah sistem kendali lengan robot yang memiliki user interface berbasis Natural User Interface yang mudah untuk dikendalikan. Lengan robot yang dapat dikendalikan mengikuti gestur gerakkan telapak tangan dan jari manusia dengan metode Motion Control secara realtime menggunakan sensor Leap Motion. Selain itu juga dirancang sistem penyimpanan dan ekstraksi database motion sehingga lengan robot memiliki kecerdasan untuk mampu melakukan gerakkan yang telah diajarkan oleh manusia. Lengan robot menggunakan 5 buah servo yang dikendalikan oleh mikrokontroler Arduino dengan sinyal PWM. Mikrokontroler Arduino dan Leap Motion dihubungkan dengan komputer melalui port USB. Frame-frame data yang diterima dari Leap Motion diproses oleh program berbasis Java pada komputer. Output dari program tersebut adalah besar sudut-sudut putaran setiap servo yang dikirim melalui komunikasi serial ke mikrokontroler Arduino. Program Penggunaan lengan robot dapat menggantikan ataupun meringankan kerja manusia secara langsung. Namun terdapat kendala yaitu sistem user interface lengan robot yang rumit. Oleh karena itu dibutuhkan user interface lengan robot yang intuitif untuk dipelajari dan mudah untuk dioperasikan. Program tersebut menggunakan algoritma inverse kinematic untuk mengkalkulasi besar sudut putaran servo. Sensor Leap Motion memiliki tingkat keakurasian yang tinggi dengan standar deviasi sumbu koordinat x, y dan z secara berturut sebesar 0.022431 mm, 0.084935 mm, dan 0.056216 mm.

Robotic arm can replace or relieve human labor directly. But there is major obstacle, the system user interface of robot arm is complicated. Therefore, it needs a robot arm user interface system that is intuitive to learn and easier to operate. This study, has designed and implemented an intuitive robot arm control system. The system uses Natural User Interface and easy to control. The robotic arm can be controlled by following the movement of a human hand and fingers gestures in realtime. Leap Motion device is used as a sensor-based hand motion control interface. This system also implemented motion database storage and extraction systems, so the robot arm has the intelligence to be able to perform movements that have been taught by humans. The robotic arm using 5 pieces of servos which are controlled by an Arduino microcontroller over PWM signal. The Arduino microcontroller and Leap Motion is connected to a computer via a USB port. Input frames of data received from Leap Motion is processed by a Java-based program. The output of the program is rotation angles of each servo that is sent through a serial communication to the Arduino microcontroller. The program uses an inverse kinematic algorithm to calculate the large of each servos angle rotation. Leap Motion sensor has a high level of accuracy with the standard deviation of 0.022431 mm, 0.084935 mm and 0.056216 mm correspond to the x,y, and z respectively."

"The field of minimally invasive surgery (MIS) has now taken centre stage in modern clinical practice. With ever changing technologies in the field of MIS, such as robotics, there is now the need to train the surgeon to the next degree. Training by simulation, whether virtual, hybrid, or real, allows the surgeon to rehearse, learn, improve or maintain their skills in a safe and stress free environment. Simulation training in laparoscopy and robotic surgery gives a true insight into the latest educational and learning techniques for new technologies in surgery. Written by an international team of experts, this illustrated text provides advice on specialised team training, non technical skills and simulation."

"ABSTRACT
Motion seringkali tidak dianggap dalam suatu konteks arsitektur. Padahal pada nyatanya manusia yang berada di dalam konteks arsitektur tersebut selalu melakukan motion di dalam aktivitasnya. Skripsi ini membahas mengenai motion dalam mempengaruhi persepsi interior yang ditangkap oleh manusia. Taman Fatahillah dipilih menjadi studi kasus untuk melihat apakah motion yang dilakukan tubuh dapat membentuk interioritas dalam suatu ruang urban. Dari studi kasus tersebut dapat dilihat dengan rhyhthmanalysis, bahwa spatial rhythm, temporal rhythm, microexperience dan strangeness pada visual turut mempengaruhi interioritas yang ditangkap oleh manusia di dalam sebuah konteks.

ABSTRACT
Motion is often not considered within architectural context. In fact, human within the context of architecture are always doing motion in their daily activities. This thesis discusses about how motion affect the interiority which perceived by human. Therefore, Taman Fatahillah is chosen as a case study to see whether the motion of the body can form interiority in an urban space. From this case study, it can be seen that rhythmanalsysis such as spatial rhythm, temporal rhythm, microexperience, and strangeness in visuals affect the interiority which perceived by human."

"This book offers a survey of the state of the art in the field of motion sickness. It begins by describing the historical background and the current definition of motion sickness, then discusses the prevalence among individuals, along with the physiological and psychological concomitants of the disorder. It reviews the incidence of motion sickness in numerous provocative motion environments and discusses various personal factors that appear to influence this aspect. Various characteristics of provocative motion stimuli are also described, together with the results of studies conducted in the laboratory, on motion simulators and at sea. Laboratory tests that could potentially be used to assess an individuals susceptibility to motion sickness and his or her ability to adapt to motion environments are presented in detail, together with the ways in which individuals might be trained to prevent motion sickness or more effectively cope with motion environments. In closing, the book reports on the cognitive-behavioral approach developed by the author (Dobie, 1963) as well as the various desensitization programs employed in military settings, and discusses the relative effectiveness of these methods in comparison to cognitive-behavioral counseling."

"The theory of compensating wage differentials predicts that there will be a
positive relationship between wages and poor working conditions and that
workers are fully compensated for poor working conditions through their wage.
In this article, we first present a theoretical model of compensating wage differentials
under the assumption of a perfectly competitive labor market to confirm
these predictions. We then show that empirical studies have found evidence
that contradicts these theoretical predictions. Specifically, we introduce
studies that show the following: (i) workers are not matched with their desired
working conditions, and those workers who report dissatisfaction with their
hours change employers to work in jobs that are more consistent with their
preferred hours; and (ii) workers are overcompensated for poor working conditions.
We provide two theoretical models that are more consistent with the
observed empirical patterns. The first is an equilibrium labor search model in
which a job is a package of wages and working hours, while the second is a
“rat-race” model in which professional employees are required to work inefficiently
long hours. Finally, we offer suggestions for offering more flexible jobs
(e.g., restricted regular employees) in the Japanese labor market. "
