Predicting Bite Force In Mammals: Two-Dimensional Versus Three-Dimensional Lever Models, Jl Davis, Se Santana, Er Dumont, Ir Grosse
Jeffrey M. Davis
Bite force is a measure of whole-organism performance that is often used to investigate the relationships between performance, morphology and fitness. When in vivo measurements of bite force are unavailable, researchers often turn to lever models to predict bite forces. This study demonstrates that bite force predictions based on two-dimensional (2-D) lever models can be improved by including three-dimensional (3-D) geometry and realistic physiological cross-sectional areas derived from dissections. Widely used, the 2-D method does a reasonable job of predicting bite force. However, it does so by over predicting physiological cross-sectional areas for the masseter and pterygoid muscles and under ...
The Optimization Of The Threshold For The Preventive Maintenance Actions In A Condition-Based Maintenance Program Via Dynamic Programming Approach, 2009 Industrial Engineering Department, University of Science and Culture
The Optimization Of The Threshold For The Preventive Maintenance Actions In A Condition-Based Maintenance Program Via Dynamic Programming Approach, Kamran Shahanaghi, Mehdi Jafarian, Majid Beikverdi, Zeinab Nezhadbiglari
The last step of a condition based maintenance (CBM) program is maintenance decision-making. This step is the most important and the most critical stage of maintenance for executive personnel and management whom work on taking maintenance actions. This decision making would be done according to certain criteria such as risk, cost, reliability and availability. This paper considered a dynamic programming model to optimization of the threshold for the preventive maintenance actions in a condition-based maintenance program. The basis of this modeling is the average cost of maintenance actions, failures and exchanges. In this paper, we improved the memory of the ...

Oscillatory And Monotonic Modes Of Long-Wave Marangoni Convection In A Thin Film, 2009 Western Kentucky University
Oscillatory And Monotonic Modes Of Long-Wave Marangoni Convection In A Thin Film, Sergey Shklyaev, Mikhail Khenner, Alexei Alabuzhev
We study long-wave Marangoni convection in a layer heated from below. Using the scaling k=O#1;#3;Bi#2;, where k is the wave number and Bi is the Biot number, we derive a set of amplitude equations. Analysis of this set shows presence of monotonic and oscillatory modes of instability. Oscillatory mode has not been previously found for such direction of heating. Studies of weakly nonlinear dynamics demonstrate that stable steady and oscillatory patterns can be found near the stability threshold.
Ironless Transducer For Measuring The Mechanical Properties Of Porous Materials, 2009 École de technologie supérieure (ETS)
Ironless Transducer For Measuring The Mechanical Properties Of Porous Materials, Olivier Doutres, Nicolas Dauchez, Jean-Michel Génevaux, Guy Lemarquand, Sylvain Mezil
Olivier Doutres Ph.D.
This paper presents a measurement setup for determining the mechanical properties of porous materials at low and medium frequencies by extending toward higher frequencies the quasistatic method based on a compression test. Indeed, classical quasistatic methods generally neglect the inertia effect of the porous sample and the coupling between the surrounding fluid and the frame; they are restricted to low frequency range (<100 Hz) or specific sample shape. In the present method, the porous sample is placed in a cavity to avoid a lateral airflow. Then a specific electrodynamic ironless transducer is used to compress the sample. This highly linear ...

Mobimaths: An Approach To Utilising Smartphones In Teaching Mathematics, Brendan Tangney, Stefan Weber, David Knowles, Jenny Munnelly, Ronan Watson, As'ad Salkham, Kevin Jennings
The teaching of mathematics at second level is well known to be a challenging issue. An overemphasis on didactic teaching, lack of encouragement to explore possible alternative solutions to problems, an overemphasis on procedure and the separation of mathematical procedures from real world problems are just some of the factors which are put forward as contributing to the difficulties in math education. Through its inherent ability to support collaboration, and contextualised learning, mobile technology offers the potential to address at least some of the issues in mathematics education. This paper describes the approach we are following to create a set ...

Upper Bounds On The Number Of Channels To Ensure Collision-Free Communications In Multi-Channel Wireless Networks Using Directional Antennas, 2009 Macau University of Science and Technology
Upper Bounds On The Number Of Channels To Ensure Collision-Free Communications In Multi-Channel Wireless Networks Using Directional Antennas, Hong-Ning Dai, Kam-Wing Ng, Min-You Wu
Recent studies have found that using multiple channels can separate concurrent transmissions and significantly improve network throughput. However, these studies have only considered wireless nodes that are equipped with omni-directional antennas, which have high interference. On the other hand, other researchers have found that using directional antennas in wireless networks can reduce interference and improve the network performance. But their studies have only considered single channel to be used in wireless networks with directional antennas. Thus, integrating the two technologies of multiple channels and directional antennas together can potentially bring more benefits. Some previous works have studies the capacity on ...

Fractionation And Characterization Of Oil Palm (Elaeis Guineensis) As Treated By Supercritical Water, 2009 University of Malaya
Fractionation And Characterization Of Oil Palm (Elaeis Guineensis) As Treated By Supercritical Water, Mahendra Varman Munusamy M.Varman, H. Miyafuji, S. Saka
Mahendra Varman Munusamy (M. Varman)
In order to investigate the potential for efficient utilization of oil palm (Elaeis guineensis), supercritical water treatment (at 380°C and 100 MPa for 8 s) was applied to fractionate extractives-free samples into water-soluble portion and water-insoluble portion. The water-insoluble portion was further fractionated into methanol-soluble portion and methanol-insoluble residue. Samples were prepared from various parts of oil palm, i.e., trunks, fronds, mesocarp fibers, shells, empty fruit bunches, and kernel cake. These fractionated products were then characterized analytically. The water-soluble and methanol-soluble portions were determined to be mainly composed of carbohydrate-derived products and lignin-derived products, respectively. The methanol-insoluble residue ...

This paper presents a framework to quantify the overall variability of the model estimations of Total Polychlorinated Biphenyls (Total PCBs) concentrations in the Niagara River on the basis of the uncertainty of few model parameters and the natural variability embedded in some of the model input variables. The results of the uncertainty analysis are used to understand the importance of stochastic model components and their effect on the overall reliability of the model output and to evaluate multiple sources of uncertainty that might need to be further studied. The uncertainty analysis is performed using a newly developed point estimate method ...
Controlled Language - Does My Company Need It?, 2009 Selected Works
Controlled Language - Does My Company Need It?, Uwe Muegge
A controlled language is a natural language, as opposed to an artificial or constructed language. Natural languages such as English or German are languages that are used by humans for general communication. A controlled language differs from the general language in two significant ways: 1. The grammar rules of a controlled language are typically more restrictive than those of the general language. 2. The vocabulary of a controlled language typically contains only a fraction of the words that are permissible in the general language.

Investigations On Tio2 And Ag Based Single And Multilayer Films For Window Glazings
A.S. Md Abdul Haseeb
In this investigation, TiO2 and Ag based single and multilayer-films were deposited on microscope glass slides with varying individual layer thicknesses by radio-frequency reactive magnetron sputtering. Prior to multilayer development, single layers of Ag and TiO2 were deposited and characterized. All the films were prepared at an elevated pressure of 3 Pa at room temperature. It was found that single layer of TiO2 showed anatase polycrystalline structure. It also exhibited high visible transmittance of above 80% and higher refractive index of 2.31 at a wavelength of 550 nm. The indirect optical band gap of the TiO2 films was estimated ...

A Short Method For The Design Of Reactive Distillation Column, 2009 Universidad de Guanajuato
A Short Method For The Design Of Reactive Distillation Column, Marcelino Carrera-Rodriguez, Juan Gabriel Segovia-Hernandez, Adrian Bonilla-Petriciolet
In this study, a short method for the design of reactive distillation is presented. The method is based on distillation lines and tray-by-tray calculations, and a new strategy is suggested to locate the reflux ratio, the number of stages, and feed tray. The material balances are solved from the outside (top and bottom) to the inside of the distillation column (feed), to ensure that the product compositions are met. To reduce the numerical difficulties, the method is based on the application of reaction-invariant composition variables. The synthesis of MTBE with the presence of inert is used as case of study ...
