This paper assesses the comprehensive macroeconomic picture of the world and Vietnam in 2017 and forecasts the outlook for 2018, and then making some policy implications for Vietnam. The world economy in 2017 is considered to be the most prosperous since 2011, thanks to the steady growth of key economies, bounced global trade, and favorable global financial conditions. However, as slow and uncertain global investment growth as well as many unpredictable factors in US government policy and Brexit, and political risks from tensions of the Korean Peninsula, 2018 will continue to witness unpredictable developments in the global economy. Faced with that situation, together with internal difficulties in the country, Vietnam should have flexible solutions, high determination and act in a drastic way in order to achieve the objectives on the economic growth and inflation as outlined. In addition, Vietnam should continue to promote the trade facilitation activities, the improvement of the bu...

The Vietnam Petroleum Institute (VPI) is implementing a multi-task national level project entitled “Research, evaluate, select and develop a pilot programme for industrial application of solutions to improve oil recovery coefficient for clastic oil bearing reservoirs of oil fields in the Cuu Long basin, on the continental shelf of Vietnam”. Specifically, detailed evaluation studies have been carried out from geological characteristics, reservoir engineering, production to EOR mechanism to develop technical criteria for the process of manufacturing and evaluating the efficiency of the chemical system to optimise the laboratory scale, propose the production and injection scenarios to optimize the development plan as well as evaluate the efficiency of increasing oil recovery coefficient on the reservoir simulation model; conduct production at pilot scale and implement industrial application testing on the field scale for clastic oil bearing reservoir, Cuu Long basin. The article presen...

This paper describes our participation in the TREC-9 Spoken Document Retrieval (SDR) track. The THISL SDR system consists of a realtime version of a hybrid connectionist/HMM large vocabulary speech recognition system and a probabilistic text retrieval system. This paper describes the configuration of the speech recognition and text retrieval systems, including segmentation and query expansion. We report our results for development tests using the TREC-8 queries, and for the TREC-9 evaluation.

Xử lý phổ hay hiệu chỉnh phổ là quá trình loại bỏ hoặc làm giảm bớt các sai số do ảnh hưởng của điều kiện khí quyển, nguồn sáng chiếu và bề mặt địa hình. Có hai loại hiệu chỉnh phổ: hiệu chỉnh tuyệt đối và hiệu chỉnh tương đối. Trong bài báo nhóm nghiên cứu tập trung tìm hiểu các phương pháp hiệu chỉnh phổ tương đối từ đó xây dựng phương pháp hiệu chỉnh phổ trên ảnh vệ tinh VNREDSat-1. Phương pháp được lựa chọn bao gồm nắn chỉnh hình học ảnh, lựa chọn các đối tượng bất biến giả định, xác định tham số chuẩn hóa. Kết quả thực nghiệm được kiểm định qua các phép phân tích thống kê giá trị độ sáng của pixel trên ảnh trước và sau chuẩn hóa phổ. Độ chính xác của kết quả thể hiện phương pháp lựa chọn là hợp lý.

DITION

This book is intended to cover the basic theoretical work in the syllabuses for Electrotechnology in Part

B

of the Department of Trade and Industry Examinations for Second and First Class Engineers and also Principles of Electricity and Electrical Engineering for Marine Engineer Cadets of the Alternative Training Scheme for Marine Engineers.

It

follows a similar pattern as the previous

yoiumes

in this series which has already proved so successful, giving emphasis on first principles, referring to numerous illustrations. providing worked examples within the text, and supplying many problems for the student to attempt on his own. The subject matter has been treated in the order and in the manner in which it would be taught at

a

college and the book is thuscomplementary to lecture notes taken at such a college. The typical examination questions at the end provide the student with the opportunity

of fin;illy

testing himself thoroughly
