Time and motion

In the course of current research the procedure of obtaining of the piecewise linear vibration systems time and frequency responses have been developed. The method is partly analytical and partly numerical and is based on combining of linear solutions of different sections in a cycle of motion. In a row with the method of obtaining of the exact steady state time and frequency response, also it is provided sensitivity analysis of the vibration isolator.

This research work is carried out in a air compressor manufacturing company which produces different models of air compressors. The work aim was to improve the productivity by reducing the total operating cycle time, unnecessary motions, material handling, and to create a standardized working environment.

In this study, in-vitro experiments were performed using a total of 24 porcine motion segments. The harvested specimens were assigned to prolong and 2 different cyclic loadings. Both disc deformations and water contents were measured to investigate how the mode and rate of loading affect the response of intervertebral disc.

This thesis proposes a new method to determine moving objects by applying some motion estimation techniques in the video compression domain. At the same time, this method will also be used to build an application that supports the identification and search of motion in home surveillance videos. The compression format of the videos in the thesis uses H264 compression (MPEG-4 part10), a popular video compression standard today.

Feedback is an integral part of our lives. Try touching your fingertips with your eyes closed; you may not succeed the first time because you have broken a feedback loop that ordinarily “regulates” your motions. The regulatory role of feedback manifests itself in biological, mechanical, and electronic systems, allowing precise realization of “functions.” For example, an amplifier targeting a precise gain of 2.00 is designed much more easily with feedback than without.

Let T (x, ε) denote the first hitting time of the disc of radius ε centered at x for Brownian motion on the two dimensional torus T2 . We prove that supx∈T2 T (x, ε)/| log ε|2 → 2/π as ε → 0. The same applies to Brownian motion on any smooth, compact connected, two-dimensional, Riemannian manifold with unit area and no boundary. As a consequence, we prove a conjecture, due to Aldous (1989), that the number of steps it takes a simple random walk to cover all points of the lattice torus Z2 is asymptotic to 4n2 (log...

a a For a 0, let W1 (t) and W2 (t) be the a-neighbourhoods of two independent standard Brownian motions in Rd starting at 0 and observed until time t. We prove that, for d ≥ 3 and c 0, t→∞ t(d−2)/d lim 1 κ a a log P |W1 (ct) ∩ W2 (ct)| ≥ t = −Id a (c) κ and derive a variational representation for the rate constant Id a (c). Here, κa is the Newtonian capacity of the ball with radius a. We show that the optimal a a strategy to realise the above large deviation is for...

Phosphoglucosamine mutase (PNGM) is a bacterial enzyme that partici-pates in the peptidoglycan biosynthetic pathway. Recent crystal structures of PNGM from two bacterial pathogens,Bacillus anthracisandFrancisella tularensis, have revealed key structural features of this enzyme for the first time.

The origin of MSC.ADAMS can be traced back to a program of research initiated by Chace at the University of Michigan in 1967. By 1969 Chace (1969, 1970) and Korybalski (Chace and Korybalski, 1970) had completed the original version of DAMN (Dynamic Analysis of Mechanical Networks). This was historically the first general program to solve time histories for systems undergoing large displacement dynamic motion. This work led in 1971 to a new program DRAM (Dynamic Response of Articulated Machinery) that was further enhanced by Angel (Chace and Angel, 1977).

Methods of collecting job analysis information 1. Direct observation Direct Observation is a method of job analysis to observe and record behavior / events / activities / tasks / duties while something is happening. 2. Work methods analysis Work methods analysis is used to describe manual and repetitive production jobs, such as factory or assembly-line jobs. Work methods analysis includes time and motion study and micro-motion analysis. 3. Critical incident technique (CIT model).
