Low-cost tape system measures velocity of acceleration

By affixing perforated magnetic recording tape to the falling end of a body, acceleration and velocity were measured. The measurement was made by allowing the tape to pass between a light source and a photoelectric sensor. Data was obtained from a readout device

Oncology and palliative care

Oncology developed as a discipline over the last decades. Treatment is concentrated on cure or palliation of the illness with the help of chemotherapy, radiotherapy or surgery. Palliative care has its origin in the hospice movement that started around 1960 in the UK. Centre of care is the patient and his family. Focus of care has moved from quantity to quality of life. Symptom control, communication, rehabilitation and care for the dying are main areas of palliative care. Palliative care and palliative medicine have only developed over the last 10 years in Germany. It is still seen as care for the dying after completion of oncological treatment. The integration of palliative care in earlier stages of the disease is essential to offer a continuity of care for the patient and his family. Principles of palliative care need also be part of medical and post-graduate training

An On Board Processor (OBP) for OAO C

A stored program computer and its application on OAO is considered. The parallel computer has a memory capacity of 16,384 words of 18 bits each, one central processor unit, two 4096 word memory units, and one input/output unit. The I/O has no direct data connection with the CPU so that all data flow between these two units must pass through memory by way of the memory data bus. The primary functions of the onboard computer are auxiliary command storage, spacecraft monitoring and malfunction reporting, data compression and status summary, and possible performance of emergency corrective action

Enabling Cross-Event Optimization in Discrete-Event Simulation Through Compile-Time Event Batching

A discrete-event simulation (DES) involves the execution of a sequence of event handlers dynamically scheduled at runtime. As a consequence, a priori knowledge of the control flow of the overall simulation program is limited. In particular, powerful optimizations supported by modern compilers can only be applied on the scope of individual event handlers, which frequently involve only a few lines of code. We propose a method that extends the scope for compiler optimizations in discrete-event simulations by generating batches of multiple events that are subjected to compiler optimizations as contiguous procedures. A runtime mechanism executes suitable batches at negligible overhead. Our method does not require any compiler extensions and introduces only minor additional effort during model development. The feasibility and potential performance gains of the approach are illustrated on the example of an idealized proof-ofconcept model. We believe that the applicability of the approach extends to general event-driven programs

Sounds in clay: a study of vibrating ceramic sculpture

The purpose of this thesis is to derive a synthesis of the sculptural aspects of form and structure and the physical principles of musical acoustics. vibrating systems: Specifically I wish to deal with three types of free-end vibrating bars; fixed-end vibrating bars; and three-dimensional vibrating bodies, each of which possesses a unique set of technical constraints within which the aesthetic requirements of form and structure may be addressed. My objective is to conduct research leading to the design and construction of a group of objects which, through the involvement and participation of the viewer, communicate both a visual and an aural statement. This concept is to be manifested primarily through the medium of clay, although glass, metal, fibers, and wood may be employed where needed to meet certain acoustic, structural, or aesthetic needs
