Abstract:

In this paper, we investigated the forward kinematic problem of the 3-6 parallel robots (Stewart platform) via a symbolic computation tool called Dixon resultant. 3-6 parallel robot is a variation of the classic 6-6 Stewart platform. First we constructed the system equations of 3-6 parallel robots with a certain coordinate system, and then gave the necessary and sufficient condition for the existence of roots of this system by resultant. With the expression of resultant, we could find the solution of the original system and determined the position of mobile platform. We also discussed how to d

Abstract:

This paper presents a method for solving the input/output problem for all planar mechanisms composed of revolute and slider joints. The solution procedure is a modification of the Dixon resultant method, which was developed to solve sets of polynomial equations; in this paper the method is applied to sets of equations which are linear in the sines and cosines of unknown angles. A particular planar multicircuit mechanism is analyzed to illustrate the solution procedure, and implementation details are discussed.

For the problem of 6-DOF serial manipulator position inverse solution, the paper proposed a new method for 6-DOF serial manipulator position inverse solution by introducing the quaternion algorithm. The relative pose transformation expression in quaternion coordinate system is proposed based on the transformation relationship between dual quaternion and double quaternion, based on which the closed equation of 6-DOF serial manipulator position inverse solution times in the form of double quaternion is established. For the obtained four position constraint equations, the Dixon resultant is const

In this paper, a new closed-form solution to the inverse static force analysis of a spatial three-spring system is presented. The system is formed by three springs each of which connects the ground at one end and joins a common point at the other. When a known force is applied to the common point of the system, the goal of inverse static analysis is to determine all the equilibrium configurations. A system of three polynomial equations in three variables is derived based on the geometric constraint and static force balancing.

AbstractThe Baranof Fan is one of three large Alaska deep-sea fans that preserve sedimentary records reflecting both tectonic and climatic processes. However, lack of drill sites in the Baranof Fan makes the depositional history across the southeastern Alaska margin still poorly understood. Sequence correlation from the adjacent Surveyor Fan to the Baranof Fan provides updated age constraints on the Baranof Fan evolution history. Results show that both the Baranof and Surveyor Fans are dominantly glacial and initiated ca. 2.8 Ma and expanded rapidly since ca. 1.2 Ma in response to the major gl

The 2-oxoacyl peptides are weakly fluorescent with emission maxima around 410 nm and excitation maxima at about 320 nm, depending on the nature and length of the peptide.

Abstract:

Abstract Background Nursing is characterized by a working articulation in shifts to ensure continuity of care throughout the 24 h. However, shift work and the resulting desynchronization of circadian rhythms may have adverse effects on nurses’ health. Aims To describe the effects of shift work and desynchronization of circadian rhythms on nurse’s health. Methods Databases: PubMed, Cinahl, Scopus, Embase and Ilisi. Search terms (free terms, MeSH): ‘nurses’, ‘shiftwork’, ‘nightwork’, ‘sleep disorder, circadian rhythm’, ‘work schedule tolerance’, ‘breast neoplasm’, ‘metabolic syndrome X’, ‘metabo

OBJETIVO: Verificar a exeqüibilidade de enxerto aorto-femoral por via laparoscópica. MÉTODO: Operamos porco de 75 kg sob anestesia geral. Empregando a técnica do avental (apron) de Dion, expusemos a aorta por laparoscopia. Brevemente, em decúbito dorsal horizontal, dissecamos um "avental" do peritônio parietal esquerdo. A dissecção prosseguiu com rotação medial do cólon esquerdo. O avental, posteriormente fixo à linha mediana, serviu de anteparo às alças intestinais. Pinçamos a aorta e realizamos enxerto aorto-femoral com o tempo abdominal totalmente laparoscópico. RESULTADO: O enxerto foi rea

Abstract. Results from the analysis of MLT wind measurements at Dixon (73.5°N, 80°E), Esrange (68°N, 21°E), Castle Eaton (UK) (53°N, 2°W), and Obninsk (55°N, 37°E) during summer 2000 are presented in this paper. Using S-transform or wavelet analysis, quasi-two-day waves (QTDWs) are shown to appear simultaneously at high- and mid-latitudes and reveal themselves as several bursts of wave activity. At first this activity is preceded by a 51–53h wave with S=3 observed mainly at mid-latitudes. After a short recess (or quiet time interval for about 10 days near day 205), we observe a regular sequenc

Abstract:

The study is devoted to the research of identification of characteristics and patterns of development of metacognitive processes and personal qualities of management activity during professionalization. Hypothesis of the existence of a direct connection between the level of professionalization of the subject and the degree of coherence of the structural organization of the main metacognitive parameters was verified in this study. Using diagnostic and experimental techniques of the study of metacognitive processes and qualities (G. Shraw, R. Dennison, M. Grant, D. LaCosta, R. Dixon, S. Haltch,

Abstract:

Background Combining bupivacaine with fentanyl for intrathecal analgesia in labor is well recognized, but dosages commonly used are arbitrarily chosen and may be excessive. This study aimed to determine the median effective dose (ED50) of intrathecal bupivacaine, defined as the minimum local analgesic dose (MLAD), and then use this to assess the effect of different doses of fentanyl. Methods In this double-blind, randomized, prospective study, 124 parturients receiving combined spinal epidural analgesia at 2-6-cm cervical dilatation were allocated to one of four groups to receive bupivacaine a
