Программный комитет выбрал стендовый доклад.

Программный комитет is a fixed academic/conference expression meaning program committee.

• программный = program-related
• комитет = committee

In conference Russian, программный комитет is the group responsible for reviewing and selecting talks, posters, etc. Even though программный can literally mean programmatic or related to a program, here the natural English translation is simply program committee.

Выбрал is the perfective past form of the verb выбрать (to choose, to select).

Russian often contrasts:

• выбирать / выбирал = imperfective, focusing on the process, repetition, or ongoing action
• выбрать / выбрал = perfective, focusing on the completed result

So:

• комитет выбирал доклад = the committee was choosing / used to choose a report
• комитет выбрал доклад = the committee chose / has selected a report

In this sentence, the selection is presented as a completed fact, so выбрал is the natural choice.

The -л marks the past tense in Russian.

Past tense forms are built from the verb stem plus -л, and then they agree in gender and number:

• выбрал = masculine singular
• выбрала = feminine singular
• выбрало = neuter singular
• выбрали = plural

Here the subject is комитет, which is a masculine singular noun, so the verb is выбрал.

Because комитет is the subject of the sentence, so it is in the nominative case.

Russian basic sentence structure here is:

• Программный комитет = the subject, nominative
• выбрал = the verb
• стендовый доклад = the direct object

You would only use another case such as комитета if the grammar required it, for example:

• нет комитета = there is no committee
• члены комитета = members of the committee

But here the committee is doing the action, so nominative комитет is correct.

Because стендовый доклад is the direct object, and доклад is an inanimate masculine noun.

In Russian, masculine singular inanimate nouns have the same form in:

• nominative
• accusative

So:

• nominative: стендовый доклад
• accusative: стендовый доклад

That is why the form does not visibly change.

Compare with an animate masculine noun:

• Я вижу студента = I see the student

Here студент becomes студента in the accusative because it is animate.

But доклад is inanimate, so the accusative looks like the nominative.

In academic or conference contexts, стендовый доклад usually means a poster presentation or poster paper.

Literally:

• стендовый = related to a stand/display board
• доклад = report, presentation, paper

In real conference English, the most natural translation is often poster presentation.

Depending on context, it might also be rendered as:

• poster
• poster paper
• poster talk (less common as a direct translation)

So even though the words literally look like stand-based report, the standard meaning is poster presentation.

Russian adjectives must agree with the nouns they describe in:

• gender
• number
• case

In this sentence:

1. программный комитет

   • комитет is masculine singular nominative
   • so the adjective is программный

2. стендовый доклад

   • доклад is masculine singular accusative, but since it is inanimate, the accusative looks like nominative
   • so the adjective is also стендовый

This is why both adjectives end in -ый here.

Russian word order is much more flexible than English word order, because case endings carry a lot of grammatical information.

So yes, you could say:

• Стендовый доклад выбрал программный комитет.

That would still mean The program committee selected the poster presentation, because:

• комитет is still nominative
• доклад is still accusative/inanimate form

However, changing the word order changes the focus or emphasis.

• Программный комитет выбрал стендовый доклад.
  Neutral word order: subject → verb → object.

• Стендовый доклад выбрал программный комитет.
  Stronger emphasis on стендовый доклад or contrastive focus, something like It was the poster presentation that the program committee selected.

So the original sentence is the most neutral and standard.

Russian does not have articles.

So nouns like комитет and доклад can mean:

• the committee / a committee
• the presentation / a presentation

The exact meaning depends on context.

In this sentence, English usually uses the because the context probably already identifies:

• the program committee
• the poster presentation

Russian leaves that unstated, and the reader understands it from the situation.

A careful stress guide is:

• програ́ммный комите́т вы́брал сте́ндовый докла́д

Notes:

• програ́ммный — stress on гра
• комите́т — stress on the last syllable
• вы́брал — stress on the first syllable
• сте́ндовый — stress on the first syllable
• докла́д — stress on the last syllable

Approximate pronunciation for an English speaker:

• pra-GRAM-my komi-TYET VY-bral STEN-da-vy dak-LAT

That is only approximate, but the stress placement is very important in Russian.

Доклад has a wider range than the English word report.

Depending on context, it can mean:

• report
• paper
• presentation
• talk

In conference language, доклад often refers to a conference presentation or paper. So in this sentence, translating it as report may sound too literal in English. A more natural conference-style translation would often be:

• The program committee selected the poster presentation.

So yes, доклад does not always correspond to just one English word.

Yes, that is a very plausible interpretation.

Because стендовый доклад refers to a poster presentation, the sentence naturally suggests that the program committee selected that submission in the poster category or selected it to be presented as a poster.

Without more context, Russian does not tell us exactly:

• whether they selected it for acceptance
• whether they assigned it to the poster session
• whether they chose it over another format

It simply states the completed fact that the program committee selected a poster presentation.

The dictionary forms are:

• программный → программный
• комитет → комитет
• выбрал → выбрать
• стендовый → стендовый
• доклад → доклад

A useful note: Russian dictionaries usually list verbs in the infinitive, so for выбрал you look up выбрать. If you want the imperfective partner, that is выбирать.
