Abstract:

Large components such as wing sections should be aligned and positioned in a desired position prior to the final manufacturing or assembly, so a digital alignment and position device based on six degree of freedom parallel manipulator with several prismatic-prismatic-prismatic-spherical branches was designed and fabricated to meet the needs. The digital alignment and position device is an alignment device based on the parallel manipulator, and it is also a positioning and holding fixture for large components manufacturing or assembly. In order to effectively and efficiently select the supporti

Abstract:

The paper focuses on the calibration of elastostatic parameters of spatial anthropomorphic robots. It proposes a new strategy for optimal selection of the measurement configurations that essentially increases the efficiency of robot calibration. This strategy is based on the concept of the robot test-pose and ensures the best compliance error compensation for the test configuration. The advantages of the proposed approach and its suitability for practical applications are illustrated by numerical examples, which deal with calibration of elastostatic parameters of a 3 degrees of freedom anthrop

Abstract:

A new improved differential evolution constrained optimization algorithm is proposed to determine the optimum path generation of a rock-drilling manipulator with nine degrees of freedom. This algorithm is developed to minimize the total joint displacement without compromising the pose accuracy of the end-effector. Considering the rule for optimal operation time and smooth joint motion, total joint displacement and minimization of the end-effector pose error are respectively taken as the optimization objective and constraints. In the proposed algorithm, the inverse kinematics solution is comput

Abstract:

This article proposes a new type of multi-actuated mechanical press with parallel topology to develop high stamping capacity. Four active limbs actuated by servomotor deliver forces and motions to moving platform, and the passive limbs are driven by moving platform to push or pull the ram. This four-input-single-output system realizes multiple actuations without causing being over-constrained. Due to infinite number of solutions for the inverse kinematics, selection of actuation schemes for given ram trajectories is more crucial. Further, the principle of virtual work is used in the inverse dy

Abstract:

This paper deals with the wrench workspace (WW) determination of parallel manipulators. The WW is the set of end-effector poses (positions and orientations) for which the active joints are able to balance a set of external wrenches acting at the end-effector. The determination of the WW is important when selecting an appropriate manipulator design since the size and shape of the WW are dependent on the manipulator’s geometry (design) and selected actuators. Algorithms for the determination of the reachable workspace and the WW are presented. The algorithms are applicable to manipulator archite

Abstract:

We study hand poses selection in bimanual fine motor skills. To understand how roles and control variables are distributed across the hands and fingers, we compared two conditions when unscrewing a screw from a watch face. When the watch face needed positioning, role distribution was strongly influenced by hand dominance; when the watch face was stationary, a variety of hand pose combinations emerged. Control of independent task demands is distributed either across hands or across distinct groups of fingers.

Abstract:

Current hand-held smart devices are supplied with powerful processors, high resolution screens, and sharp cameras that make them suitable for Augmented Reality (AR) applications. Such applications commonly use interaction techniques adapted for touch, such as touch selection and multi-touch pose manipulation, mapping 2D gestures to 3D action. To enable direct 3D interaction for hand-held AR, an alternative is to use the changes of the device pose for 6 degrees-of-freedom interaction. In this article we explore selection and pose manipulation techniques that aim to minimize the amount of touch.

A typical serial manipulator consists of a servo motor, a serial mechanism and an independent joint placed between the motor and the serial mechanism. Both the time-varying characteristics of the inertia of the serial mechanism and the flexibility characteristics of the independent joint are widely found in serial manipulator servo drive systems. These two characteristics not only increase the resonance magnitude of serial manipulators, but also affect the dynamic characteristics of the system.

Input devices such as Nintendo Wiimotes are often used to select and manipulate virtual objects. While simple to use and easily available, these devices have some limitations.

We propose overcoming these limitations by using a smartphone as an interaction device. Smartphones, like Wiimotes, are readily available and easy to operate.

In computerized adaptive testing, the most commonly used valuating function is the Fisher information function. When the goal is to keep item bank security at a maximum, the valuating function that seems most convenient is the matching criterion, valuating the distance between the estimated trait level and the point where the maximum of the information function is located. Recently, it has been proposed not to keep the same valuating function constant for all the items in the test. In this study we expand the idea of combining the matching criterion with the Fisher information function. We als

Abstract:

The goal of the research was to analyse the development of the idea of the public service broadcasting (PSB) in Lithuania as one of Post-Soviet countries that restored its independence in 1990. The Lithuanian case serves in revealing the great variety of ways to interpret the idea of the PSB, the possibilities to manipulate various notions, and the way the fate of the PSB can be affected by politicians and competing business groups. In this research we distinguished the following stages of the PSB concept formation in Lithuania: the first debates (the development of legislative basis), and att

Abstract Abstract 564 Insertional oncogenesis poses a severe hurdle to current gene therapy for blood disorders. The semi-random insertion of retroviral vectors combined with the inability for prolonged ex vivo culture of hematopoietic stem cells (HSCs) prohibits prospective integration site selection. The advent of induced pluripotent stem cells (iPSCs) offers for the first time the possibility of generating patient-specific stem cells that can be extensively manipulated in vitro, thus creating a unique platform for precise genetic engineering. Here, we present a novel strategy for the geneti

Abstract. Airline route maps show the flights an airline operates between destination airports. Maps like these tend to become cluttered quickly. The clutter depends on the amount of flights to display; the routes of flight paths, the balance between shorter (e.g., domestic) and longer (e.g., intercontinental) flights, and the geographic locations of route endpoints each influence the amount of clutter.Flights are typically shown as semantically uniform, despite having varied characteristics such as departure or arrival times, frequencies, or passenger volumes, among others. Most maps only ind

Abstract:

Abstract Acute Promyelocytic Leukemia (APL) accounts for 5% of all cases of acute myeloid leukemia (AML). This disease is highly curable with all-trans-retinoic acid (ATRA) based therapy. In non-APL AML, ATRA has limited activity, and little is known about mechanisms of ATRA resistance. The apparent selective efficacy of ATRA in PML/RARα-associated APL poses an important question as to whether the presence of this fusion protein renders APL uniquely susceptible. Two compelling arguments can be made to counter this view. First, experiments in vitro show that ATRA effectively differentiates HL-6

Genetic manipulation as selective reproduction – a preliminary theological-ethical assessment Genetic manipulation – the technology in which genes are placed in embryos and gametes of animals – with the purpose of creating certain intended genetic characteristics, has taken place on a limited but indeed astonishing scale. Although the application of genetic manipulation is not yet possible for humans, because of a number of genetic and technical problems, research in this field is taking place at a terrific speed. In this article attention is given to the question whether genetic manipulations

Abstract:

Abstract Sexual reproduction often leads to selection that favors the evolution of sex-limited traits or sex-specific variation for shared traits. These sexual dimorphisms manifest due to sex-specific genetic architectures and sex-biased gene expression across development, yet the molecular mechanisms underlying these patterns are largely unknown. The first step is to understand how sexual dimorphisms arise across the genotype-phenotype-fitness map. The emergence of “4D genome technologies” allows for efficient, high-throughput, and cost-effective manipulation and observations of this process.

Abstract:

Automating the double-hull block welding improves the shipbuilding efficiency and mitigates health risk to the welders. Due to the unique challenge posed by the internal structures, existing technologies are at most semi-autonomous. Believing that mobility is key to full autonomy, we employ mobile robot technology to transport the welding manipulator, treating the internal structures as obstacles. Though many robot designs for obstacle scaling exist, there is no selection guideline. To this end, we surveyed existing robots and came out with a taxonomy to explain the design philosophies behind

Abstract:

Global agriculture production is under serious threat from rapidly increasing population and adverse climate changes. Food security is currently a huge challenge to feed 10 billion people by 2050. Crop domestication through conventional approaches is not good enough to meet the food demands and unable to fast-track the crop yields. Also, intensive breeding and rigorous selection of superior traits causes genetic erosion and eliminates stress-responsive genes, which makes crops more prone to abiotic stresses. Salt stress is one of the most prevailing abiotic stresses that poses severe damages t

Abstract:

IntroductionThe common origin of the adjective “corporeal” and the noun “corpse” in the Latin root corpus points to the value of mortuary practices for investigating how the human body is objectified. In post-mortem rituals, the body—formerly the manipulator of objects—becomes itself the object that is manipulated. Thus, these funerary rituals provide a type of double reflexivity, where the object and subject of manipulation can be used to reciprocally illuminate one another. To this extent, any consideration of corporeality can only benefit from a discussion of how the body is objectified thr

Introduction In a 1984 New York Times interview, Germaine Greer discussed the quite different views that have surrounded her supposed attitude towards sex. As she put it, “People seem to think I'm Hugh Hefner and that the reason women started having sex is because I told them to” (qtd. in De Lacy). This view had, however, shifted by the 1980s. As she told reporter Justine De Lacy, “Now they are saying that I'm against sex.” In this article, I tease out Greer’s remarks about the supposed transformation of her political persona.

Perhaps for this reason, the Oxford English Dictionary begins with reference to the far more mundane and accessible sun and features of the human body, in defining north as; “in the direction of the part of the horizon on the left-hand side of a person facing the rising sun” (OED Online).
