While today’s general purpose manipulators contain six degrees of freedom, effective reduction in degrees of freedom occurs from singularity regions and from workspace obstacles. It is argued that the future general purpose manipulators will contain seven degrees of freedom, and that one particular kinematic design is superior to other possible 7 degree of freedom kinematic designs. Considerati...

State educational spending policies strongly impact the funding of local schools. While some US states have removed school spending authority from local residents, others continue to encourage local control. In this paper we explore the effects of changes in state educational spending policies on Tiebout sorting by examining the location choice of young and elderly households, both within and a...

OBJECTIVE The goal of this study was to assess linkages between microclimate and longer-term ENSO-related weather forcing on the week-to-week changes in dengue prevalence in Matamoros, Tamaulipas, Mexico, over a recent decade of dengue observations. MATERIAL AND METHODS An auto-regressive model to evaluate the role of climatic factors (sea-surface temperature) and weather (maximum temperature...

The effectiveness of four different electron donors, specifically methanol, ethanol, glycerol, and sulfide (added as Na(2)S), were evaluated in post-denitrifying bench-scale moving bed biofilm reactors (MBBRs). With the requirement for more wastewater treatment plants to reach effluent total nitrogen levels approaching 3 mg/L, alternative electron donors could promote more rapid MBBR startup/ac...

Any elementary textbook on statistical mechanics will try to convince you that energy is everything w.r.t. phase separation. The goal of this thesis is to show otherwise.

The peculiar construction of the temporomandibular joint allows the mandible to move according to six degrees of freedom. In Dental Medicine, is essential to know this movement to simulate the temporomandibular joints, to position tooth moulds in articulators and to reproduce the mandibular movements in order to insure a satisfactory occlusion. In this work a facial arc, commonly used in Dental...

UNLABELLED A few studies have performed to evaluate the temperature variation influences over on the stroke rates in Brazil. METHOD 176 medical records of inpatients were analyzed after having had a stroke between 2004 and 2006 at Hospital Israelita Albert Einstein. The temperature preceding the occurrence of the symptoms was recorded, as well as the temperature 6, 12 and 24 hours before the ...

A Doppler reflectometer system has recently been installed in the stellarator TJ-II. The system is optimized for the Q-band (33-50 GHz) and the high-curvature plasmas produced in TJ-II. The launch angle of the microwave beam can be controlled by a steerable mirror to obtain angles between +/-20 degrees enabling the measurement of perpendicular wave numbers in the range of 3-15 cm(-1). The avail...

In this paper we address the problem of f inding the spatial position and orientation of an object from a single image. It is assumed that the image formation process and an object model are known in advance. Sets of image lines are backprojected and constraints on their spatial interpretations are derived. A search space is then constructed where each node represents a space feature with a mod...

Frost formation on an evaporator causes significant problems by decreasing inlet air flow. It is important for a precise prediction to understand the dominant factor of the frost formation. In this paper, the frost layer on the cold plate is experimentally obtained with different velocities while maintaining a surface temperature at -20 degrees Celsius. The mass and height of the frost layer is...
