  • Tiêu cự (Focal length) Tiêu cự của máy ảnh là thông số cho biết góc nhìn của máy ảnh, nghĩa là khoảng phạm vi mà máy ảnh có thề “thâu tóm” được. Ống kính có tiêu cự 50 mm được coi là chuẩn (tính theo hệ máy ảnh sử dụng phím nhựa 35 mm), vì loại ống kính này có góc nhìn gần giống với mắt người nhất. Ống kính có tiêu cự nhỏ hơn thì gọi là ống kính góc rộng, tức là có góc chụp “wide”. iêu cự của máy ảnh là thông số cho biết góc nhìn của...

  • Kỹ thuật RFLP là kỹ thuật nghiên cứu tính đa hình chiều dài của các phân đoạn DNA dựa trên điểm cắt các enzim giới hạn. Khi ủ DNA với enzim giới hạn ở dung dịch đệm thích hợp ở pH, nhiệt độ thích hợp sẽ sẽ tạo ra những phân đoạn DNA với kích thước khác nhau, từ đó lập nên các bản đồ gen. Tham khảo chương hai "Kỹ thuật RFLP - Restriction fragment length polymorphisms" để hiểu hơn về vấn đề này.

  • This paper presents a multi-neuro tagger that uses variable lengths of contexts and weighted inputs (with information gains) for part of speech tagging. Computer experiments show that it has a correct rate of over 94% for tagging ambiguous words when a small Thai corpus with 22,311 ambiguous words is used for training. This result is better than any of the results obtained using the single-neuro taggers with fixed but different lengths of contexts, which indicates that the multi-neuro tagger can dynamically find a suitable length of contexts in tagging. ...

  • Web search engines today typically show results as a list of titles and short snippets that summarize how the retrieved documents are related to the query. However, recent research suggests that longer summaries can be preferable for certain types of queries. This paper presents empirical evidence that judges can predict appropriate search result summary lengths, and that perceptions of search result quality can be affected by varying these result lengths. These findings have important implications for search results presentation, especially for natural language queries. ...

  • We examine the problem of choosing word order for a set of dependency trees so as to minimize total dependency length. We present an algorithm for computing the optimal layout of a single tree as well as a numerical method for optimizing a grammar of orderings over a set of dependency types. A grammar generated by minimizing dependency length in unordered trees from the Penn Treebank is found to agree surprisingly well with English word order, suggesting that dependency length minimization has influenced the evolution of English. ...

  • Dialog participants in a non-mixed initiative dialogs, in which one participant asks questions exclusively and the other participant responds to those questions exclusively, can select actions that minimize the expected length of the dialog. The choice of question that minimizes the expected number of questions to be asked can be computed in polynomial time in some cases. The polynomial-time solutions to special cases of the problem suggest a number of strategies for selecting dialog actions in the intractable general case. ...

  • Negative life events play an important role in triggering depressive episodes. Developing psychiatric services that can automatically identify such events is beneficial for mental health care and prevention. Before these services can be provided, some meaningful semantic patterns, such as , have to be extracted. In this work, we present a text mining framework capable of inducing variable-length semantic patterns from unannotated psychiatry web resources.

  • We present a language-independent and unsupervised algorithm for the segmentation of words into morphs. The algorithm is based on a new generative probabilistic model, which makes use of relevant prior information on the length and frequency distributions of morphs in a language. Our algorithm is shown to outperform two competing algorithms, when evaluated on data from a language with agglutinative morphology (Finnish), and to perform well also on English data.

  • Cable length tests can be very helpful in troubleshooting cabling problems with UTP. The Cabling infrastructure or cable plant in a building is expected to last at least ten years. Cabling related problems are one of the most common causes of network failure. The quality of cabling components used, the routing and installation of the cable, and quality of the connector terminations will be the main factors in determining how trouble-free the cabling will be. Prior to starting the lab, the teacher or lab assistant should have several correctly wired CAT 5 cables to test.
