Kinetic dataset - aqueous oxidation of aliphatic acids by hydroxyl radical
No full textIn the five spreadsheets included in this dataset, the values of the bimolecular reaction rate coefficients for the aqueous oxidation of aliphatic carboxylic acids (protonated forms), carboxylate anions (deprotonated forms) by hydroxyl radical (OH), and their activation parameters are compiled. These data include the literature data (cited within the readme.txt file) and the values of bimolecular reaction rate coefficients. The first spreadsheet (298K_literature_refs) contains raw literature data, compiled bimolecular reaction rate coefficients at 298K with literature references. The second spreadsheet (298K_SAR) contains the reviewed data, used for developing and optimizing a kinetic structure-activity relationship model. The third spreadsheet (T_dept_literature_refs) contains raw literature data, compiled bimolecular reaction rate coefficients, measured between 278 and 328 K. The fourth spreadsheet contains the reviewed data, bimolecular reaction rate coefficients, measured between 278 and 328 K, with outliers removed and missing values (when different temperatures were used between studies) filled out with values calculated using the Arrhenius expression – these data were used for developing and optimizing a kinetic structure-activity relationship model. The fifth spreadsheet (T_dept_activaton_only) lists the values of activation parameters derived via the Arrhenius expression for the carboxylic acids under investigation. </p

Stereoscopic Camera for Autonomous Mini-Robots Applied in KheperaSot League
No full textChinapirom T, Witkowski U, Rückert U. Stereoscopic Camera for Autonomous Mini-Robots Applied in KheperaSot League. In: FIRA Robot World Congress 2007, on CD. San Francisco, USA; 2007.This paper presents a stereoscopic vision system for the
mini-robot Khepera. The vision system performs objects
detection by using the stereo disparity and stereo
correspondence. The stereoscopic vision system enhances
robot’s visual perception ability by grabbing stereo images
and analysis 3D objects, while the robot doesn’t need to
move. The simple principle of our stereo vision is the less
displacement of correspondence pixels shows that the
pixels object is far away. To realize the stereo vision and
its calculation algorithms, the mini robot needs a powerful
FPGA and micro-controller module as well as 2D color
cameras. An application of Khepera equipped with the
stereoscopic camera is robot soccer in the KheperaSot
league. In the match, the robot has to be able to detect its
environment, i.e. the ball, walls, goals and its opponent
A Bluetooth Scatternet for the Khepera Robot
No full textDu JL, Witkowski U, Rückert U. A Bluetooth Scatternet for the Khepera Robot. In: 4th International Symposium on Autonomous Minirobots for Research and Edutainment (AMiRE). Buenos Aires, Argentina; 2007: 189-195.Radio-based communication plays a vital role in multi-robot systems.
Bluetooth is an energy-efficient communication technology suited for resourcelimited mini-robots such as the Khepera. However, the maximum number of nodes in a Bluetooth piconet is limited, while scatternets - networks of piconets - have not been fully specified. In this paper we present a Bluetooth scatternet using Bluetooth communication sticks developed in our research group. In our solution, bridge nodes carrying two of such Bluetooth sticks are used to interconnect piconets. Beside the developed hardware, issues such as routing as well as topology control are addressed. Finally, data rate and latency measurements are presented for the implemented solution
Extension Module for Application-Specific Hardware on the Minirobot Khepera
No full textNiemann J-C, Witkowski U, Porrmann M, Rückert U. Extension Module for Application-Specific Hardware on the Minirobot Khepera. In: Autonomous Minirobots for Research and Edutainment (AMiRE 2001). Paderborn, Germany; 2001: 279-288.In this paper a hardware extension for the minirobot Khepera is presented. We are researching into algorithms for neural data processing and their hardware implementation by increasingly using the minirobot Khepera. This robot is supposed to record its environment continuously and to map obstacles. This is the basis for the implementation of an efficient navigational system. As the algorithms in question are complex and since the microcontroller on the Khepera does not possess the necessary processing capacity, it is requisite to develop a discrete hardware module that extends the Khepera
