In this article, a new combined adaptive method is used for a two-link robot. One of the advantages of proposed controller is that it does not depend on the exact parameters such as joints weight. Also the controller can reach itself to real parameters. In many applications of robots in industry the weight and moment of inertia are changed intentionally and it would not be an easy task for the ...

As shown in previous work, the duty cycle can be adapted to the traffic of the applications in higher OSI layers. Though, extensive simulations has to be performed in order to determine the properties of the adaptation algorithm. The goal of this paper is to analytically analyze the adaptation behavior, such that the deployment engineer of the adaptation algorithm is freed from extensive simula...

In computer graphics boolean operations have been around for years. In contrast, point sampled geometry models represent a new and stirring side of graphics which is researched mostly in the last couple of years. Papers about the combination of CSG and surfels only appeared recently, and it’s hard to find a generalized overview of the possible choices. Therefor our goal is to fill this hole, to...

As a new media, social network gains a wide range of social influence, and the social network based ecommerce becomes more and more popular, therefor, the study of information propagation is great of significance. In this paper, we will presents a trust based information propagation model, just as the trust between people in real life. First, employ the algorithm of data mining on personal info...

In today’s modeling tools, the graphical user interfaces are required to be accurate and intuitive to use. Most tools therefor rely on additional 3D-widgets (e.g., arrows or circles) that enable the user to operate towards a desired modeling result. In this paper we present, for the first time, a method that makes these widgets obsolete. We propose to use simple geometric primitives such as pla...

Covering algorithms for binary classification build a list of one-sided partial models in a greedy manner. The original motivation therefor stems from the context of rule learning where the expressiveness of a single rule is too limited to serve as standalone model. If the model space is richer, the decomposition into subproblems is not strictly necessary but separately solved subproblems might...

The recent emergence of multi-drug resistant bacteria has rendered many common antibiotics ineffective and therefor novel drugs are needed. Antimicrobial peptides have proven applicable in this aspect as they can form self-assembled pore structures in the lipid bilayer of bacterial cells. The exact pore formation is shrouded in controversy and largely unknown as it is difficult to determine emp...

Management problems in the development of software have been addressed by a focus on improvement of the development process the last years. However, in most cases the product is sold, not the process that created it. Therefor, process improvement should have a product focus. This paper presents the practical implementation of a method for product focused software process improvement in Tokheim,...

Music, sound and brain activity share similarities in how we can measure or create them, namely as combinations of time-dependent processes (repetition and history) and time-independent events (discontinuous, nonlinear or catastrophic processes). Furthermore, time is fundamental in how we measure both brain activity and sound objectively, and how we define relationships e.g. between notes as we...

To describe the structure of a system, the UML Class Diagram yields the means-of-choice. Therefor, the Class Diagram provides concepts like class, attribute, operation, association, generalization, aggregation, enumeration, etc. When students are introduced to this diagram, they often have to solve exercises where texts in natural language are given and they have to model the described systems....
