In a multiple linear regression model, there are instances where one has to update the regression parameters. In such models as new data become available, by adding one row to the design matrix, the least-squares estimates for the parameters must be updated to reflect the impact of the new data. We will modify two existing methods of calculating regression coefficients in multiple linear regres...

In this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition Petri nets. The mobile agent system contains two mobile agents called DCA and UNA. It sends out agents to update antivirus on client computers in a network. Each agent takes on a specified responsibility. First, DCA roams through the network and check the last d...

In this paper, we present our approaches for the Mediaeval Emotional Impact of Movies Task. We extract features from multiple modalities including audio, image and motion modalities. SVR and Random Forest are used as our regression models and late fusion is applied to fuse different modalities. Experimental results show that the multimodal late fusion is beneficial to predict global affects and...

Several inviscid models in hydrodynamics and geophysics such as the incompressible Euler vorticity equations, the surface quasi-geostrophic equation and the Boussinesq equations are not known to have even local well-posedness in the corresponding borderline Sobolev spaces. Here H is referred to as a borderline Sobolev space if the L∞-norm of the gradient of the velocity is not bounded by the H-...

We present an optimal on-line algorithm for the List Update Problem when the request sequence has some particular structure.

Because of heavy weights and large turning radii, large truck (LT) movements have very different characteristics than those of smaller vehicles, such as passenger cars. This difference makes collection of LT volume data very important for accurate analysis of traffic stream characteristics in transportation planning and engineering. Since LT travel patterns are seasonal, data obtained by survey...

A linear description for the economic lot-sizing problem consisting of exponentially many linear inequalities was given by Barany, Van Roy and Wolsey in 1984. Using this formulation we present a dual algorithm for the economic lot-sizing problem, which is of the same complexity as the Wagner and Whitin dynamic programming algorithm. Besides its use in sensitivity analysis the dual algorithm als...

Didactic strategies in the classroom are influenced by factors like class size, prior class knowledge and level of class attention. In large classes, student activation has to follow different didactic approaches in order to obtain ad-hoc feedback from individual students than in small classes. One approach to increase class attention are classroom voting tools (known from quiz show formats for...

Background: Losses in lower extremity muscle strength/ power, muscle mass and deficits in static and particularly dynamic balance due to aging are associated with impaired functional performance and an increased fall risk. It has been shown that the combination of balance and strength training (BST) mitigates these age-related deficits. However, it is unresolved whether supervised versus unsupe...
