Humans demonstrate a remarkable ability to parse complicated motion sequences into their constituent structures and motions. We investigate this problem, attempting to learn the structure of one or more articulated objects, given a time-series of feature positions. We model the observed sequence in terms of “stick figure” objects, under the assumption that the relative joint angles between stic...

We present a prototype of a new musical interface for Japanese drumming techniques and styles. Our design used in the Aobachi drumming sticks provides 5 gesture parameters (3 axes of acceleration, and 2 axes of angular velocity) for each of the two sticks and transmits this data wirelessly using Bluetooth® technology. This system utilizes minimal hardware embedded in the two drumming sticks, al...

We study combinatorial principles known as stick and club. Several variants of these principles and cardinal invariants connected to them are also considered. We introduce a new kind of side-by-side product of partial orderings which we call pseudo-product. Using such products, we give several generic extensions where some of these principles hold together with ¬CH and Martin’s Axiom for counta...

As John Berger and Jean Mohr pointed out in The Seventh Man [5] an arresting photographic essay of European migrant labour in the 1970s the incapacitated and dying migrant is a murky presence within capitalism’s unconscious. Parodying the mounting tension between the global demand for healthy aspirational migrant workers and the responsibility for their long term well-being and care, Berger wro...

A nurse in providing nursing care cannot be separated from risks that can cause work accidents. Occupational accident is an unexpected event not expected when doing work. Based on work-related and disease recapitulation data at X Depok Hospital, it shows during the 2018-2022 period there were 6 incidents of needle sticks 2 nurses slipping. The purpose this study to determine OSH risk management...

This paper presents a novel method for speckle reduction in ultrasonic images. Firstly, a particular filtering kernel is defined by decomposing the local rectangular neighborhood into asymmetric sticks pointing outside with variable orientation from the investigated pixel. Then the local mean and variance along each stick are calculated using a template based convolution algorithm. Finally, a p...
