Virtual Reality

It means to immerse the analyst within the

simulated world. Although, it is often seen as being synonymous with man-machine hardware interfaces, the technology must incorporate methods for building dynamic digital (virtual) worlds, which is a typical problem of computer simulation.

        1. Translate the following sentences into Russian.

  1. After the space shuttle Columbia crashed on February 1, 2003, analysts at the National Aeronautics and Space Administration (NASA) used modeling software applied by the National Transportation Safety Board (NTSB) for studying crashes.

  2. The purpose of simulations produced by ICT and others involved in computer modeling goes far beyond mere entertainment: at a fraction of the expense and risk involved in war games involving real troops and equipment, commanders and their subordinates can study and learn from battle.

  3. This article describes a method for estimating parameters of a reflection model from a single color image taken by a CCD camera.

  4. There is another type of computer keyboard, which is designed to make things go a bit "smoother" on your fingers and makes typing easier, which is suggested for people who are having a hard time learning how to type or those who use the designated fingers on the designated keys.

  5. One way to represent an elapsed time is with a simple arithmetic data type, as with the following function to compute the elapsed time between two calendar times.

        1. Translate the following sentences into English.

  1. Монокристалические и одномерные наноструктуры диоксида титана были бы намного предпочтительны так как обладают изумительными свойсвами и характеристиками, такими как высокая подвижность электронов, максимальную удельную поверхность и даже высокую механическую прочность.

  2. Любой объект, который вы видите или трогаете, имеет трехмерную структуру и может быть измерен: длина, ширина и высота.

  3. Группа исследователей из Сингапура, используя металло-решетчатую наноструктуру, сумела получить в несколько раз отчетливое цветное изображение высокого разрешения, чем при обычных методах.

  4. Computer-aided design (CAD), also known as computer-aided design and drafting (CADD), is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design.

  5. Язык моделирования виртуальной реальности позволяет создать «виртуальные миры» объединённые в сеть посредством Интернета и соединенные гиперссылками со всемирной паутиной.

SPEAKING SECTION

        1. Answer the following questions.

  1. What are the advantages and disadvantages of computer modeling?

  2. What is the difference between computer modeling and computer simulations?

  3. What are the advantages and disadvantages of computer simulations?

  4. How to model? What to take into account? What to neglect?

  5. Do we need to describe neglected features indirectly?

  6. What formalism to use in modeling?

  7. Is the model appropriate? Does it serve its purpose? Why/Why not?

  8. A model is always done with a certain “resolution”. Do we have right level of abstraction?

  9. In what aspects does the features/behavior of the model differ from what is expected?

  10. In what way model differs from “reality” (other existing models or experimental results)?

  11. Validation: are the results valid (for the presumptive purpose)?
