The memory hierarchy model is a powerful tool that can separate the stall time in a multi-level cache. However, since no tool currently exists that is able to compute this information, it is diicult to validate the model. In this respect, a processor simulator can help. With a simulator, we can directly observe the stall time due to cache misses, and thus obtain cpi 0. We succesfully validate t...

We address the well-known limitation of Huxley and Simmons 1971 (HS) model. It is a statement that at physiological value stiffness in actomyosin complex, distribution myosin motors becomes microscopically uniform (all are either pre- or post-power stroke conformation) after an infinitesimal displacement from stall (isometric contractions) conditions. Such behavior fiber level would generate ne...

To understand the physics of the complex vortex flow field of the F/A-18 aircraft during maneuvering at high incidences, a series of flow visualizations were conducted in the IAR 0.38 x 0.51m water tunnel. A 1/72-scale model was tested on the new orbital-platform rotary apparatus at angles of attack from 20o to 65o with sideslip angles in the range 10 . It was found that the aerodynamic behavio...

The objective of this study is to employ feedback control to maximize time-average lift on a low-aspect-ratio wing by directly modifying the three-dimensional dynamics of the wake vortices. Flow control around such wing at post-stall angles of attack is numerically investigated at a low Reynolds number of 300 with blowing along the trailing edge. Motivated by the existence of time-periodic high...

Flow control is applied to a three-dimensional post-stall flow around a rectangular low-aspect-ratio wing. Steady actuation is used to examine effective flow control setups that modify the vortex dynamics in the wake and achieve increase in lift. For one of the setups, oscillatory forcing is then used to examine the influence of actuation frequency. It is found that sinusoidal actuation require...

Background: Lameness is a huge problem in intensive livestock production, leading to enormous losses terms of stress animals, less reproductive ability and increased chances mastitis. Zero grazing system needed for today’s but it has also led lameness chances, unnecessarily body condition score mastitis incidences. On the other hand, pasture promotes cows exhibit natural behaviour, which improv...

• Lack of desi9n and en9ineering stall knowledge (and time) • Lack of central computer or MIS stall knowledge • Lack of operator or foreman acceptance • Lack of information on equipment and software capabilities • Lack of inside or outside programming capabilities • Lack of outside consultants to assist the effort • Lack of higher management interest • Lack of suppliers to take entire system re...

The bleak news was first presented by Franz Fischler, the European fisheries commissioner to a meeting of Irish fishermen in Dublin last month: closure of fisheries around Ireland, Britain and other areas of the north-east Atlantic for cod and related species were likely to be the last chance for any sort of recovery and sustainable future for fishing for these species. Scientists from the Inte...

A series of Navier-Stokes simulations of a complete Boeing 777-200 aircraft con gured for landing is obtained using a structured overset grid process and the OVERFLOW CFD code. At approach conditions, the computed forces for the 777 computation are within 1.5% of experimental data for lift, and within 4% for drag. The computed lift is lower than the experiment at maximum-lift conditions, but sh...
