BACKGROUND A craniocerebral trauma caused by firearms is a complex injury with high morbidity and mortality. One of the most intriguing and controversial part in their management in salvageable patients is the decision to remove the bullet/pellet. A bullet is foreign to the brain and, in principle, should be removed. Surgical options for bullet extraction span from conventional craniotomy, thro...

Boost phase missile tracking is formulated as a nonlinear parameter estimation problem, initialized with an unscented transformation, and updated with a scaled unscented Kalman filter.

In order to improve the security of the Military kinds of network this work is proposed. Here the position of missile navigates as per the user’s requirement. The user sends the co-ordinates through pc based server on the base station. For security purpose encryption is done with RC4algorithm implementation. The system that uses Human Computer Interaction and Visualization technology provides s...

a statistical report of 912 battle casualtiesadmitted in a special unit of the neurological surgery department during 49 months of the recent war was given. methods of their evaluation, operative categories, management poli¬cies including techniques of missile and bullet removal, and their complications were discussed.

ted to allow efficient ballistic missiles , the paper describes a recently developed ted estimation/guidance design paradigm n several innovative concepts that provides satisfactory homing performance against ly maneuvering targets. The new paradigm veloped and tested first by using a simplified constant speed interception scenario model. paper the integrated estimation/guidance m is validated ...

Uncertainties in certain features of target geometries result in a loss of confidence in the signature assessment of the target. Knowledge of the impact to a target’s radar cross section (RCS) due to changes to specific target features can assist to identify whether uncertainty in a certain target feature warrants a loss of confidence in the target signature. This study will allow a development...

A circular polarization sensor is feasible to detect a sea-skimming cruise missile in a solar corridor. We report the simulated performance results of a shipboard medium-wave infrared (MWIR) circular polarization sensor to detect a sea-skimming missile above rough sea surface. The sensor observed total and circular target and sea clutter signals at night and during daytime in and out of the sol...

The purpose of this study was to evaluate the epidemiological characteristics of the mandibular fractures relating to gender, age, the etiology of injury, and the rendered treatment modalities and complications. The data of the patients who sustained mandibular fractures were retrieved and were analyzed retrospectively, and based on these data a descriptive analysis was conducted. A total of 11...
