The Investigation Of Vehicle Crashes Occasionally Presents A Question Of Who Was Driving A Vehicle At the Time Of A Collision. Many Accidents Result In Drivers And Passengers Being Thrown About The Passenger compartment, Or Being Completely Ejected From Their Vehicle. In Such Cases, Driver, Passenger, And witness Statements Are Often In Conflict With One Another; Especially When The Driver Could Potentially be Charged With A Crime, Or Be Held Liable For Damages Resulting From A Crash. In Many Cases, Physical evidence Can Provide The Forensic Engineer With Information To Conduct A Proper Reconstruction Of The crash, To Perform An Occupant Kinematic Analysis, And To Make A Determination And Render An Opinion regarding Who Was Driving The Vehicle At The Time Of The Crash.  this Paper Will Address Methodologies For Data Collection And Crash Reconstruction That Can Be Used in Determining Who Was Driving A Vehicle At The Time Of A Crash. It Will Include Instruction To The At-Scene investigator As To Data That Can Be Helpful In Such Analyses And Determinations. Two Case Studies Will Be presented In Which The Author Analyzed The Crash Data To Determine Who Was Driving.

The reconstruction of shooting incidents based on the terminal bullet trajectory is commonly carried out over short distances using a linear trajectory simplification model. However, when shooting incidents, such as sniper attacks, take place over longer distances, linear simplification models destabilize and result in large errors in determining the location of the shooter. In such cases, it becomes necessary to account for a large number of variables affecting the flight path of the bullet. While linear simplification models for bullet trajectories do not require robust engineering analysis methods, reverse modeling of long-range bullet trajectories can only be carried out using numerical methods for solving the differential equations of projectile motion. This paper will explore methods for employing computational engineering methods to model the trajectories of bullets with a focus on reverse modeling from the trajectory terminus. In this way, the forensic engineer can use basic measurements of the terminal angle of the bullet trajectory combined with appropriate knowledge of the firearm and ammunition to model the bullet’s path back to a probable location of the shooter. This paper will focus on methods that the forensic engineer can employ when solving problems involving determination of the location of a shooter based on limited physical evidence at the scene. Computational analysis tools will be presented.

Reconstructed Surfaces

In recent years there has been a trend in the structure determination of reconstructed surfaces to use high energy electron diffraction techniques, and to employ a kinematic approximation in analyzing the intensities of surface superlattice reflections. Experimentally this is motivated by the great success of the determination of the dimer adatom stacking fault (DAS) structure of the Si(111) 7 × 7 reconstructed surface.While in the case of transmission electron diffraction (TED) the validity of the kinematic approximation has been examined by using multislice calculations for Si and certain incident beam directions, far less has been done in the reflection high energy electron diffraction (RHEED) case. In this paper we aim to provide a thorough Bloch wave analysis of the various diffraction processes involved, and to set criteria on the validity for the kinematic analysis of the intensities of the surface superlattice reflections.The validity of the kinematic analysis, being common to both the TED and RHEED case, relies primarily on two underlying observations, namely (l)the surface superlattice scattering in the selvedge is kinematically dominating, and (2)the superlattice diffracted beams are uncoupled from the fundamental diffracted beams within the bulk.

In Reply.— We thank Dr Smith for his interesting perspective regarding screening for child abuse. We had hoped our article would help physicians focus on the verbal evidence of abuse and show how insensitive the physical evidence is in predicting which child had been abused sexually. To apply the principles of sensitivity and specificity to the assessment of child abuse or sexual abuse, we must have a gold standard which characterizes these problems. Neither a child protective services decision nor a legal determination of "no proven abuse" can be used as a gold standard, unless we can accept a "gold standard" made of iron pyrite.
