Pacific capelin Mallotus catervarius are planktivorous small pelagic fish that serve an intermediate trophic role in marine food webs. Due to the lack of a directed fishery or monitoring of capelin in the Northeast Pacific, limited information is available on their distribution and abundance, and how spatio-temporal fluctuations in capelin density affect their availability as prey. To provide information on life history, spatial patterns, and population dynamics of capelin in the Gulf of Alaska (GOA), we modeled distributions of spawning habitat and larval dispersal, and synthesized spatially indexed data from multiple independent sources from 1996 to 2016. Potential capelin spawning areas were broadly distributed across the GOA. Models of larval drift show the GOA’s advective circulation patterns disperse capelin larvae over the continental shelf and upper slope, indicating potential connections between spawning areas and observed offshore distributions that are influenced by the location and timing of spawning. Spatial overlap in composite distributions of larval and age-1+ fish was used to identify core areas where capelin consistently occur and concentrate. Capelin primarily occupy shelf waters near the Kodiak Archipelago, and are patchily distributed across the GOA shelf and inshore waters. Interannual variations in abundance along with spatio-temporal differences in density indicate that the availability of capelin to predators and monitoring surveys is highly variable in the GOA. We demonstrate that the limitations of individual data series can be compensated for by integrating multiple data sources to monitor fluctuations in distributions and abundance trends of an ecologically important species across a large marine ecosystem.

Subject. After the collapse of the USSR, smaller countries chose different paths in their economic policy during the globalization and the multipolar world. The EU, USA and Russia made a palpable contribution to the economic policy of smaller countries. Some countries of the former USSR failed to find their course, while the others immediately followed their development strategy and stuck to it persistently. Objectives. I examine the economics of the monodirectional strategy of smaller countries of the former USSR. I also evaluate how the countries found their position among different leading countries as points of attraction. The study is based on the assumption that the single direction of the national development and adherence to the same point of attraction will ensure the sustainable development. However, the economic development level depends on the health of a certain economy as a point of attraction. Methods. The study is based on the systems approach, comparative and statistical methods for analyzing macroeconomic data series. Results. I investigated the dynamics of key macroeconomic data in the Republic of Belarus, Latvia and Estonia, such as GDP per capita in current values, unemployment rate and Purchasing Power Index. Given the current phase of globalization and multipolar world, it is crucial for smaller countries to choose a development strategy to follow persistently and achieve proper macroeconomic indicators that depend on the economic stability of counties they treat as their benchmarks. Conclusions and Relevance. I should mention the successful economic policy of Estonia and Latvia, which followed the same course as the other EU countries, as opposed to the Republic of Belarus tending to the policy of the Russian Federation. Nevertheless, the monodirectional development strategy also helps smaller countries ensure their economic stability.

Information searching based on users’ query, which is hopefully able to find the documents based on users’ need, is known as Information Retrieval. This research uses Vector Space Model method in determining the similarity percentage of each student’s assignment. This research uses PHP programming and MySQL database. The finding is represented by ranking the similarity of document with query, with mean average precision value of 0,874. It shows how accurate the application with the examination done by the experts, which is gained from the evaluation with 5 queries that is compared to 25 samples of documents. If the number of counted assignments has higher similarity, thus the process of similarity counting needs more time, it depends on the assignment’s number which is submitted.

Library is one of the facilities which provides information, knowledge resource, and acts as an academic helper for readers to get the information. The huge number of books which library has, usually make readers find the books with difficulty. Universitas Multimedia Nusantara uses the Senayan Library Management System (SLiMS) as the library catalogue. SLiMS has many features which help readers, but there is still no recommendation feature to help the readers finding the books which are relevant to the specific book that readers choose. The application has been developed using Vector Space Model to represent the document in vector model. The recommendation in this application is based on the similarity of the books description. Based on the testing phase using one-language sample of the relevant books, the F-Measure value gained is 55% using 0.1 as cosine similarity threshold. The books description and variety of languages affect the F-Measure value gained. Index Terms—Book Recommendation, Porter Stemmer, SLiMS Universitas Multimedia Nusantara, TF-IDF, Vector Space Model

This paper deals with studying some properties of a monogenic function defined on a vector space with values in the Clifford algebra generated by the space. We provide some expansions of a monogenic function and consider its application to study solutions of second-order partial differential equations.
