The classical mean-variance investment model is simple, elegant, and popular. As such, it is also subject to criticisms. One unsatisfactory feature of the model is that variance treats the upside and downside equally as risks. In this regard, the downside Lower Partial Moments (LPM) are more attractive as alternative risk measures, since they only penalize the downside. In the meanwhile, consid...

This paper describes a new binocular tracking method using Log Polar Mapping (LPM) which approximately represents the mapping of the retina into the visual cortex in primate vision. Using LPM makes it possible not only to obtain both a high central resolution and a wide eld of view, but also to signi cantly reduce processing image data. In this paper, LPM is performed in software by lookup tabl...

The reduplication in Kor. sālsal and sălɨlɨ ‘gently’ presents interesting phonological problems in 1) what should be the underlying base, *sal or salɨ? and 2) how the length alternation should be explained. In this paper I first present a serial analysis in which these examples are explained as cases of overand under-application, and then examine how it compares with a similar analysis in recen...

We study the power of a tournament organizer in manipulating the outcome of a balanced single-elimination tournament by fixing the initial seeding. This problem is known as agenda control for balanced voting trees. It is not known whether there is a polynomial time algorithm that computes a seeding for which a given player can win the tournament, even if the match outcomes for all pairwise play...

We tackle multiple people tracking across multiple non-overlapping surveillance cameras installed in a wide area. Existing methods attempt to track people across cameras by utilizing appearance features and spatio-temporal cues to re-identify people across adjacent cameras. However, in relatively wide public areas like a shopping mall, since many people may walk and stay arbitrarily, the spatio...

In this study, two types of marker-based tracking systems for Augmented Reality were developed: a tracking system using line markers and a tracking system using circular markers. Both markers were designed for use inside buildings such as nuclear power plants, which are very complicated and in which it is difficult to paste many large markers. To enlarge the area in which tracking is available ...

This paper describes our work on visualizing the information of a tennis match. We use competition trees to organize the information of a tennis match and visualize the competition trees by the top-nesting layered maps with translucent colored layers. We create iconic representations to describe the detailed information of athletic events in an intuitive manner. Specialized views of the informa...

For ML and Haskell, accurate warnings when a function definition has redundant or missing patterns are mission critical. But today’s compilers generate bogus warnings when the programmer uses guards (even simple ones), GADTs, pattern guards, or view patterns. We give the first algorithm that handles all these cases in a single, uniform framework, together with an implementation in GHC, and evid...
