Sistem perpipaan pemadam kebakaran di perumahan Salonsa merupakan fasilitas yang vital, sistem ini tidak boleh rusak/gagal karena harus bisa digunakan pada tiap waktu. perppaan mampu bertahan dari fenomena water hammer menyebabkan fluktuasi tekanan. Akan dilakukan simulasi menggunakan software AFT Impulse dengan skenario valve hydrant ditutup cepat, dan pompa mati mendadak, untuk mengetahui efe...

Aim of the present study was to describe the muscle fibre type composition and body composition of well-trained hammer throwers. Six experienced hammer throwers underwent the following measurements: one repetition maximum in squat, snatch, and clean, standing broad jump, backward overhead shot throw and the hammer throw. Dual x-ray absorptiometry was used for body composition analysis. Fibre ty...

We present an improved MR brain image registration algorithm, called TPS-HAMMER, which is based on the concepts of attribute vectors and hierarchical landmark selection scheme proposed in the highly successful HAMMER registration algorithm. We demonstrate that TPS-HAMMER algorithm yields better registration accuracy, robustness, and speed over HAMMER owing to (1) the employment of soft correspo...

The purpose of this study was to investigate the variables that contributed most to maximum throwing distance in the hammer throw event in track and field. A 41item survey instrument was developed to collect data regarding national level collegiate hammer throwers throughout the United States. Multiple regression analysis for hammer throw personal record (PR) yielded a significant model (r=0.81...

The motion of the striking point on the piano hammer was measured before and during string contact by means of an optical equipment. The measurements resolved the motion in two perpendicular components; in the striking direction (vertical), and in the string direction (horizontal). The influence of dynamic level and touch on the hammer motion was studied. Three different types of touch were eva...

This paper presents a novel pneumatic Down-The-Hole (DTH) hammer with self-rotation bit used for rock drilling, and the mechanical structure working principle are mainly covered. A unique mechanism ratchet pawl incorporated in DTH is proposed percussion-rotation drilling to break rock. The drill can rotate while pipe stays still because of design reduces friction between borehole. Firstly, rati...

Introduction: As a carrier of different sensors, moles can penetrate into the regolith automatically and keep investigating the subsurface environment continuously. In this section, features of several moles with different applications are introduced to explain why we choose a hammer-driven mole to study. Mole driven by a hammer: In this section, the penetrating principle of a hammer-driven mol...

The central problem of designing intelligent robot systems which learn by demonstrations of desired behaviour has been largely studied within the field of robotics. Numerous architectures for action recognition and prediction of intent of a single teacher have been proposed. However, little work has been done addressing how a group of robots can learn by simultaneous demonstrations of multiple ...
