Vibrational Characteristics of Dummy Headforms
The Hybrid III and NOCSAE headforms are two headforms used in impact testing, though their vibrational characteristics are not well understood. They may have different kinematic responses in various impact scenarios if the impact excites any of their natural frequencies; resonance is especially …

The development of finite element model for Malaysian Female Anthropometric Dummy
In recent years, dummy development for crash test have grown rapidly to decrease the fatalities during crash. These dummies are generated based on anthropometric database consisting of several percentile. Anthropometric data is very important in terms of ergonomics to specify the physical …

Development and Validation of a Finite Element Dummy Lower Limb Model for Under-body blast Applications
An under-body blast (UBB) refers to the use of a roadside explosive device to target a vehicle and its occupants. During Operation Iraqi Freedom, improvised explosive devices (IEDs) accounted for an estimated 63% of US fatalities. Furthermore, advancements in protective equipment, combat triage, …

Development, Calibration, and Validation of a Finite Element Model of the THOR Crash Test Dummy for Aerospace and Spaceflight Crash Safety Analysis
… Test Device for Human Occupant Restraint (THOR) dummy was developed, calibrated, and validated for use in aerospace and spaceflight impact analysis. A previously developed THOR FE model was first evaluated under spinal loading. The FE model was then updated to reflect recent updates made to the …

Effects of season and plane of nutrition upon serum lipids and protein of white-tailed deer
… in kg. of wild deer X₁ = condition index¹ (a dummy variable) X₂ = condition index² (a dummy variable) X₃ = age in years X₄ = season¹ (a dummy variable) X₅ = polar lipids (percentage of total lipids) X₆ = cholesterol (percentage of total lipids) The multiple R² for the equation above was 0.57 y …

Properties Of Logistic Regression Models With Correlated Observations
… model and an estimator obtained by using dummy variables in the usual logistic model, are investigated. These two estimators are shown to be, in general, asymptotically biased. Some conditions are given for consistency of the two estimators. Expressions for the asymptotic variances of the …

An ARDL modelling approach to international tourism demand in Tanzania
… were selected as the main determinants. Dummy variables for the September 2001 USA terror attack and the 1998 Tanzania US embassy bombing were also included in the model. The dummy variables were treated in two different ways, to capture the temporary and permanent effects these events …

Impacts of foreign assistance on less-developed countries' agricultural productivity
… moving average of aid expenditures. Second, dummy variables were introduced to allow the effects of aid to differ by income levels, yearly factors, and geographical regions. An inter country pooled cross section and time-series data for a set of 59 countries was used in the models from …

"For good design, you pay now; for bad design, you pay later"--or do you?
… Operating Income (NOI). This base data set, MSA dummy variables and architectural attribute dummy variables (created by the authors) formed the backbone of the research. Multiple log linear regression analysis was conducted to identify the economic effects of good design.

Determinants of FDI flows to Sub- Saharan Africa: Does economic development play a role?
… using fixed effects and random effects models. A dummy variable is included to represent economic development. The dummy was created by assessing each nations country classification by income level, according to the World Bank, in each year included in the analysis. The study opted against taking …

Planejamento e habitualidade são determinantes na poupança familiar?
… que o planejamento, medido pela variável dummy orçamento, perde significância. Tal fato pode ter se dado devido aos efeitos não observáveis (características fixas de cada indivíduo), e ao haver controle sobre isso, a dummy não possui mais efeito. Desta forma, o orçamento pode revelar algo …

Switched capacitor, self referencing sensing scheme for high density magneto-resistive memories
… element is compared against the signal from a dummy element. The resulting signal is stored and again is compared against a signal of opposite polarity which is generated from the same element. This process is called self referencing and is done to minimize offset problems. The special features …
