This article presents a novel 3D inverted pendulum that can balance on one of its corners using only single reaction wheel. is achieved by careful design the mass moment inertia in such way along two principal tilt axes significantly different. The consequence time-scale separation underlying dynamics, which renders system controllable. We show controllability maximized when ratio values amount...

This paper suggests two test architectures for testing distributed, concurrent systems: a global tester that has total control over the distributed system under test (SUT) and, more interestingly, a distributed tester comprising several concurrent tester components. The test architectures rely on a grey-box testing approach that allows to observe internal interactions of the SUT by the tester. ...

An investigation on the robustness of a torque vectoring control based on an inverse disturbance observer architecture for a rear wheel driven vehicle with electric single wheel drives is presented within this contribution. To ensure robust control parameters, specifications for eigenvalues (Γ-stability) and bounds on weighted sensitivity and complementary sensitivity functions in frequency dom...

4 Lightweight wheelchair stair-climbing attachments. Step stair-climbing mechanism targeted for wheelchair application is presented in Section 3. Finally a.This paper focuses on presenting the development of a stair-climbing wheelchair mechanism with high single-step capability. The mechanism is based on front.A stair climbing mechanism is a semi-automated vehicle, which has the. One is for mak...

In this paper, the effect of the cell-temperature on the performance of photovoltaic (PV) module is evaluated. The evaluation is based on a mathematical module (single diode equivalent circuit) and practically based on solar module tester (SMT). Solara®130W PV crystalline silicon module was used in this simulation. The SMT is able to supply a constant irradiance level (1000W/m2) or any other de...

We describe a low-cost, functional tester for the MacII that allows students to test and debug digital systems interactively. This tester provides a large number of programmable I/O signals and can be used to test chips, boards and subsystems. Test programs are easily written using a simple, intuitive interface and we expect a variety of interactive graphical testing and debugging environments ...

We introduce the notion of a Canonical Tester for a class of properties on distributions, that is, a tester strong and general enough that "a distribution property in the class is testable if and only if the Canonical Tester tests it". We construct a Canonical Tester for the class of symmetric properties of one or two distributions, satisfying a certain weak continuity condition. Analyzing the ...

INTRODUCTIONSuppression subtractive hybridization (SSH) is one of the most powerful and popular methods for generating subtracted cDNA or genomic DNA libraries. This technique can be used to compare two mRNA populations and obtain cDNAs representing genes that are either overexpressed or exclusively expressed in one population as compared to another. It can also be used for comparison of genomi...
