W.E.B. DuBois\u27s The Comet and Contributions to Critical Race Theory: An Essay on Black Radical Politics and Anti-Racist Social Ethics

No longer considered the exclusive domain of legal studies scholars and radical civil rights lawyers and law professors, critical race theory has blossomed and currently encompasses and includes a wide range of theory and theorists from diverse academic disciplines. Its most prominent practitioners, initially law professors and left scholars, most of them scholars of color employing the work of the breathtakingly brilliant African American lawyer, scholar, and activist Derrick Bell (2005) as their primary point of departure, borrowed from many of the political and theoretical breakthroughs of black nationalism, anti-racist feminism, poststructuralism, and postmodernism. They also employed and experimented with new cutting-edge literary techniques and social science methodologies that shaped and shaded their work and burgeoning socio-legal discourse, ultimately giving it a fierceness and flair unheard of in the history of legal studies. Early critical race theorists\u27 work acutely accented the vexed bond between law and racial power (Crenshaw, Gotanda, Peller & Thomas, 1995, p. xiii). The emphasis on race and power quickly led them to the critique of white supremacy and the subordination of people of color, not simply in the legal system, but in society as a whole (p. xiii)

Predication and the Frege–Geach problem

Several philosophers have recently appealed to predication in developing their theories of cognitive representation and propositions. One central point of difference between them is whether they take predication to be forceful or neutral and whether they take the most basic cognitive representational act to be judging or entertaining. Both views are supported by powerful reasons and both face problems. Many think that predication must be forceful if it is to explain representation. However, the standard ways of implementing the idea give rise to the Frege-Geach problem. Others think that predication must be neutral, if we’re to avoid the Frege-Geach problem. However, it looks like nothing neutral can explain representation. In this paper I present a third view, one which respects the powerful reasons while avoiding the problems. On this view predication is forceful and can thus explain representation, but the idea is implemented in a novel way, avoiding the Frege-Geach problem. The key is to make sense of the notion of grasping a proposition as an objectual act where the object is a proposition

Combinatorial Interpretations of Fibonomial Identities

The Fibonomial numbers are defined by $$\begin{bmatrix}n \\ k \end{bmatrix} = \frac{\prod_{i=n-k+1} ^{n} F_i}{\prod_{j=1}^{k} F_j}$$ where $F_i$ is the $i$th Fibonacci number, defined by the recurrence $F_n=F_{n-1}+F_{n-2}$ with initial conditions $F_0=0,F_1=1$. In the past year, Sagan and Savage have derived a combinatorial interpretation for these Fibonomial numbers, an interpretation that relies upon tilings of a partition and its complement in a given grid.In this thesis, I investigate previously proven theorems for the Fibonomial numbers and attempt to reinterpret and reprove them in light of this new combinatorial description. I also present combinatorial proofs for some identities I did not find elsewhere in my research and begin the process of creating a general mapping between the two different Fibonomial interpretations. Finally, I provide a discussion of potential directions for future work in this area

Combinatorial Proofs of Fibonomial Identities

We provide a list of simple looking identities that are still in need of combinatorial proof

System and Method for Tensioning a Robotically Actuated Tendon

A tendon tensioning system includes a tendon having a proximal end and a distal end, an actuator, and a motor controller. The actuator may include a drive screw and a motor, and may be coupled with the proximal end of the tendon and configured to apply a tension through the tendon in response to an electrical current. The motor controller may be electrically coupled with the actuator, and configured to provide an electrical current having a first amplitude to the actuator until a stall tension is achieved through the tendon; provide a pulse current to the actuator following the achievement of the stall tension, where the amplitude of the pulse current is greater than the first amplitude, and return the motor to a steady state holding current following the conclusion of the pulse current

Concurrent Path Planning with One or More Humanoid Robots

A robotic system includes a controller and one or more robots each having a plurality of robotic joints. Each of the robotic joints is independently controllable to thereby execute a cooperative work task having at least one task execution fork, leading to multiple independent subtasks. The controller coordinates motion of the robot(s) during execution of the cooperative work task. The controller groups the robotic joints into task-specific robotic subsystems, and synchronizes motion of different subsystems during execution of the various subtasks of the cooperative work task. A method for executing the cooperative work task using the robotic system includes automatically grouping the robotic joints into task-specific subsystems, and assigning subtasks of the cooperative work task to the subsystems upon reaching a task execution fork. The method further includes coordinating execution of the subtasks after reaching the task execution fork

LeguTec – mechanische Beikrautregulierung im Sojaanbau in Luxemburg

Fünf mechanische Beikrautregulierungsmethoden im Sojaanbau werden unter praxisnahen Bedingungen auf drei Bio-Betrieben in Luxemburg seit dem Frühjahr 2018 getestet. Die Feldversuche werden in vier Wiederholungen einschließlich Kontrollparzellen durchgeführt. Verschiedene Boniturparameter werden vor und nach jeder Regulierung sowie zur Blüte und zur Ernte erhoben, um die Effizienz der verwendeten Techniken in Bezug auf den Ertrag zu bewerten. Erste Resultate zeigen höhere Erträge und eine geringere Beikrautdeckung zur Blüte in den Hackvarianten im Vergleich zu den Striegelvarianten

Method and apparatus for automatic control of a humanoid robot

A robotic system includes a humanoid robot having a plurality of joints adapted for force control with respect to an object acted upon by the robot, a graphical user interface (GUI) for receiving an input signal from a user, and a controller. The GUI provides the user with intuitive programming access to the controller. The controller controls the joints using an impedance-based control framework, which provides object level, end-effector level, and/or joint space-level control of the robot in response to the input signal. A method for controlling the robotic system includes receiving the input signal via the GUI, e.g., a desired force, and then processing the input signal using a host machine to control the joints via an impedance-based control framework. The framework provides object level, end-effector level, and/or joint space-level control of the robot, and allows for functional-based GUI to simplify implementation of a myriad of operating modes
