Given the agreement among TCSCF, MP2, and MRMP methods, it is concluded that the structure of Si9H12 is symmetric, that dynamic correlation does not play a major role in determining the structure, and that DFT incorrectly predicts Si9H12 to be buckled.

Abstract This paper introduces a design method of hardware-in-the-loop simulation system applied to certain type image-guided missile. By studying the characteristics missile, working principle image-guidance is analyzed, mathematical scheme and are designed, mechanism RTX analyzed. Established real-time based on RTX+Windows, analyzed delay computer, simulated launch control flight motion simul...

Advanced shipboard radar systems will be required to detect, track and classify ballistic missile targets and re-entry vehicles, as well as perform traditional Anti-Air Warfare (AAW) operations. New Open Architecture Systems, including COTS hardware as well as open system software, are required to implement the necessary algorithms for successful missile defense. Lockheed Martin MS2 has been de...

During a 15-year period from August 1964 to August 1979, 48 patients with gunshot wound of the esophagus (24 of the cervical, 17 of the thoracic, and seven of the abdominal) were treated at Grady Memorial Hospital. In the majority of the patients, the initial history, physical findings, and chest roentgenograms were nondiagnostic for esophageal injury. Esophageal perforation was mainly suspecte...

The story begins long before the dawn of recorded history, at the time when man learned to use sticks and stones as weapons. We shall trace the injuries caused by weapons, which became increasingly more deadly from the Stone Age, through the ancient civilisations of Egypt and Greece to modern times. What do we mean by a penetrating wound of the head? There are three kinds of head injury. First,...

The thesis deals with the guidance and control of a fighter aircraft in air combat. From the modeling perspective, the thesis formulates realistic air combat optimization problems and games in which inherent uncertainties of air combat are taken into account. From the solution perspective, the thesis develops on-line methods for the near-optimal feedback solution of the constructed models. The ...

Tracking a ballistic missile in its reentry phase is one of the missile defence challenges as these reentry vehicles penetrate with large aerodynamic loads and sudden decelerations from exoatmospheric to endoatmospheric phase. With the advent of anti-ballistic missiles, the main goal of missile defence systems is to track the reentry vehicle to locate them precisely for allowing midair altitude...

We describe JOINT DEFENDER, a new two-sided optimization model for planning the pre-positioning of defensive missile interceptors to counter an attack threat. In our basic model, a defender pre-positions ballistic missile defense platforms to minimize the worst-case damage an attacker can achieve; we assume that the attacker will be aware of defensive pre-positioning decisions, and that both si...

Sebagai salah satu bentuk peristiwa traumatis, kekerasan seksual masa kecil menghilangkan kesadaran penyintas sehingga beberapa tidak bersedia untuk mencari, memberi perhatian, dan mengikuti proses pemulihan. Namun, itu bisa didapatkan kembali. Pertanyaan yang ingin dijawab dalam artikel ini adalah pendekatan apa, secara psikologis teologis, dapat digunakan gereja, sebagai pendamping bagi merek...
