Predicative Adjective

This article studies the function of Copular Predicate Constructions in everyday English conversation. We compare predicate adjective constructions (PA) and constructions with a predicate nominal containing an adjective (PAN). We ask whether the attributive function of the adjective or the presence of a noun in the PAN leads to a difference in function in the two constructions. We propose that in most cases the adjective determines the function of the construction, leading to many parallels in usage between the PA and PAN constructions. A comparison with predicate nominal constructions (PN), in contrast, shows that not including an adjective in the constructions leads to a different set of meanings and implications. The conversational usage of these constructions provides evidence for a partial correspondence of form to function: Copular Predicate Constructions often constitute a complete turn in conversation, and if not a full turn, form their own prosodic units. Other properties of these constructions—the definiteness of the NP and the presence or absence of a N—correspond to different interactional work. A comparison of all three constructions shows that the adjective plays a determining interactional role, despite differences in syntactic configuration.

The Cost

Currently, the penetration of industrial robots into all sectors of the economy is increasing. However, there is an acute problem of conducting preliminary tests. The use of the digital twin as a replacement for the industrial robot is driven by high economic costs. In order to reduce the cost of the project, a solution is proposed to conduct preliminary tests on the developed model. The article developed a mathematical model of one of the drives of the industrial robot manipulator Yaskawa Motoman MH50-35. The model is suitable for researching the movement of the robot' tool. A mathematical description of a permanent magnet synchronous motor SGMJV-09A in a rotating coordinate system is given and a block diagram of the power part of the drive is made. A system for regulating the position of the robot's tool with a nonlinear position controller has been synthesized. Based on the results of modeling the operation of an electric drive in the Matlab Simulink environment, the degree of correspondence of the developed model to a real object was assessed and conclusions were drawn about the limits of its applicability for studying the operation of an electric drive of a robotic arm. The accuracy of working out the task for turning the wrist is 0.0001 rad, there is no overshoot in position, and the time for completing a full turn of the tool is 1.07 s.

Large Rotations

Abstract A new method is developed for determining both a satisfactory location of a workpiece and a suitable mounting-angle of the tool for planar RPR robots that can provide dexterous workspace. The method is an analytical representation of the geometry of the robot and the task, and is particularly well suited to applications in which the task requires large rotations of the end-effector. It is determined that, when the task requires that the end-effector rotate a full turn at just two locations and when the first or third joint in the robot is rotatable by one turn, then the radial location of the workpiece is fixed in the workcell but its angular location is not fixed. When the mounting-angle of the tool is also a variable, the method accommodates tasks in which the tool must rotate a full turn at three locations on the workpiece. The results are presented as coordinates of points in a two-dimensional Cartesian reference frame attached to the workcell. Consequently, a technician or an engineer can determine the location for the workpiece by laying out these coordinates directly in the workcell. Example problems illustrate the method. Practical applications include welding and deposition of adhesives.

Rotational Preference in GymnasticsIn gymnastics, most skills incorporate rotations about one or more body axes. At present, the question remains open if factors such as lateral preference and/or vestibulo-spinal asymmetry are related to gymnast's rotational preference. Therefore, we sought to explore relationships in gymnast's rotation direction between different gymnastic skills. Furthermore, we sought to explore relationships between rotational preference, lateral preference, and vestibulo-spinal asymmetry. In the experiment n = 30 non-experts, n = 30 near-experts and n = 30 experts completed a rotational preference questionnaire, a lateral preference inventory, and the Unterberger-Fukuda Stepping Test. The results revealed, that near-experts and experts more often rotate rightward in the straight jump with a full turn when rotating leftward in the round-off and vice versa. The same relationship was found for experts when relating the rotation preference in the handstand with a full turn to the rotation preference in the straight jump with a full turn. Lateral preference was positively related to rotational preference in non-expert gymnasts, and vestibulo-spinal asymmetry was positively related to rotational preference in experts. We suggest, that gymnasts should explore their individual rotational preference by systematically practicing different skills with a different rotation direction, bearing in mind that a clearly developed structure in rotational preference between different skills may be appropriate to develop more complex skills in gymnastics.

Overconstrained Mechanisms

This paper deals with a 6R single-loop overconstrained spatial mechanism that has two pairs of revolute joints with intersecting axes and one pair of revolute joints with parallel axes. The 6R mechanism is first constructed from an isosceles triangle and a pair of identical circles. The kinematic analysis of the 6R mechanism is then dealt with using a dual quaternion approach. The analysis shows that the 6R mechanism usually has two solutions to the kinematic analysis for a given input and may have two circuits (closure modes or branches) with one or two pairs of full-turn revolute joints. In two configurations in each circuit of the 6R mechanism, the axes of four revolute joints are coplanar, and the axes of the other two revolute joints are perpendicular to the plane defined by the above four revolute joints. Considering that from one configuration of the 6R mechanism, one can obtain another configuration of the mechanism by simply renumbering the joints, the concept of two-faced mechanism is introduced. The formulas for the analysis of plane symmetric spatial triangle are also presented in this paper. These formulas will be useful for the design and analysis of multiloop overconstrained mechanisms involving plane symmetric spatial RRR triads.

Semantic Agreement

Abstract A classical topic in the syntax of the mainland Scandinavian languages is so-called pancake clauses where there seemingly is disagreement between the subject and the predicative adjective, as in Pannekaker er godt ‘Pancakes(f):indf:pl be:prs good:n:sg’; the subject is in the plural, whereas the predicative adjective is in the neuter singular. According to one of the several approaches, these clauses display a type of semantic agreement. Recently, it has also been argued that there are at least four different types of pancake constructions. In this article, the semantic relationship between the different constructions is investigated further. It is argued that, diachronically, pancake agreement started with subjects interpreted as virtual, ungrounded processes, and that the absence of grounding has been reinterpreted as absence of spatial boundedness in the latest kind of pancake construction. The analysis is supported by a diachronic corpus investigation. The emphasis on virtual reference is a new feature with the current paper, and it enables us to set aside an objection against the semantic agreement analysis. The diachronic corpus investigation enables us to revise, empirically, earlier suggestions as to when the pancake constructions originated: They are well attested from the mid-1800s, in both Swedish and Norwegian Nynorsk.

ABSTRACT As a result of the taxonomic survey of the pigmented Euglenophyceae of Lago da Ponte, an artificial pond located at the Porto Alegre Botanical Garden, State of Rio Grande do Sul, Southern Brazil and samples gathered later on from this same water body, a new species of Phacus (Euglenophyceae, Phacaceae), P. multifacies Alves-da-Silva & C. Bicudo, sp. nov., is here described and proposed as new to science. Cell displacement turning ventrally one full turn round itself and also rotating around its longitudinal axis and the presence of a dorsal wing-like expansion next to the caudal process are the main diagnostic features of the new species. Physical and chemical information on the pond water is presented.
