This paper introduces a tree-form constant market share (CMS) model for analyzing growth causes in international trade based on multi-level classification. The treeform CMS is a collection of CMS models at different levels, including the entire, branchand leaf-models, which consists of a large amount of information and has a wide application spectrum. Basic properties of this model are investig...

We construct a network of member states of the United Nations General Assembly based on how similarly they vote on resolutions. We describe a similarity metric that we feel better describes the inter-nation relationships than previously proposed models. Next, we introduce a mechanism to infer the best diplomatic path between countries that do not have high similarity in voting. Lastly, we creat...

We present a method for dehazing images. A dark envelope image is derived with the bilateral minimum filter and a bright envelope is derived with the bilateral maximum filter. The ambient light and transmission of the scene are estimated from these two envelope images. An image without haze is reconstructed from the estimated ambient light and transmission.

We have already proposed a bilateral control scheme with energy balance monitoring under time-varying communication delay. In this paper, experimental results using the proposed control scheme over the computer network are shown. In the previous work, we dealt with a situation when the communication is in breakdown. However, we did not discuss how to recover the system after the communication l...

We investigate the four parameter family of bilateral Gamma distributions. The goal of this paper is to provide a thorough treatment of the shapes of their densities, which is of importance for assessing their fitting properties to sets of real data. This includes appropriate representations of the densities, analyzing their smoothness, unimodality and asymptotic behaviour.

There is strong evidence that people exploit their bargaining power in competitive markets but not in bilateral bargaining situations. There is also strong evidence that people exploit free-riding opportunities in voluntary cooperation games. Yet, when they are given the opportunity to punish free-riders, stable cooperation is maintained although punishment is costly for those who punish. This ...

This paper explores the impact of immigrants on the imports, exports and productivity of serviceproducing firms in the U.K. Immigrants may substitute for imported intermediate inputs (offshore production) and they may impact the productivity of the firm as well as its export behavior. The first effect can be understood as the re-assignment of offshore productive tasks to immigrant workers. The ...

In recent years, there has been renewed interest in bilateral symmetry detection in images. It consists in detecting the main bilateral symmetry axis inside artificial or natural images. State-of-the-art methods combine feature point detection, pairwise comparison and voting in Hough-like space. In spite of their good performance, they fail to give reliable results over challenging real-world a...
