In this concluding part of a series of papers on tetrahedral polynomial extension operators, the existence of a polynomial extension operator in the Sobolev space H(div) is proven constructively. Specifically, on any tetrahedron K, given a function w on the boundary ∂K that is a polynomial on each face, the extension operator applied to w gives a vector function whose components are polynomials...
Coordination of F-actin and microtubule dynamics is important for cellular motility and morphogenesis, but little is known about underlying mechanisms. short stop (shot) encodes an evolutionarily conserved, neuronally expressed family of rod-like proteins required for sensory and motor axon extension in Drosophila melanogaster. We identify Shot isoforms that contain N-terminal F-actin and C-ter...
Remodularization aims improving software modularity and making more explicit component and architectural information. In order to remodularize their applications, maintainers need tools enabling component and architecture recovery. There exist several approaches for the extraction of component information from Java source code. Only few of them provide automatic support taking into account mode...
Transient simulations of refrigeration cycles are crucial for evaluating new refrigerants. Previously developed transient simulation tool was capable of simulating refrigeration systems using refrigerants R22 and R134a and was validated with experimental data; however, incorporating non-traditional refrigerants such as R744 (carbon dioxide) change the cycle operation beyond the capabilities of ...
To achieve the highest level performance with computer controlled machines, the flexibility of the system must be taken into account. Feedforward methods are often the most desirable means of eliminating vibration. The fastest motions can be obtained by using the timeoptimal flexible-body command. These commands depend on the system parameters, actuator limits, and the desired motion. Input sha...
High-frequency ac link conversion offers a possible way to produce reduced-cost inverters for low-voltage dc sources such as fuel cells. The control complexity can be addressed by adapting pulse-width modulation (PWM) techniques. Here, a multi-carrier pulse-width modulation (PWM) approach is introduced as a convenient way to implement a high-frequency link inverter. The approach is a direct ext...
The ability of eight commercially available thermophilic DNA polymerases to sequentially incorporate fluorescently labeled nucleotides sequentially was analyzed by a gel based primer extension assay. Cy5-dUTP or a variant nucleotide in which the linker had been lengthened by 14 atoms between the dye and the nucleobase were compared. We found that the Cy5-dUTP with a longer linker resulted in lo...
Energy detectors are optimum to detect uncorrelated Gaussian signals or GLRT to detect completely unknown signals; in both cases, noise background must be uncorrelated Gaussian. However, energy detectors degrade when noise background is non-independent and nonGaussian. An extension is presented in this paper to deal with this situation. Independence is achieved by means of a matrix linear trans...
Tracking is the main factor which limits the safe working electric stress of insulation in power system applications. Polymer samples have been tested in laboratory conditions according to ASTM D2303 on accelerated inclined plane tracking test. In this paper, a model based on improved Weibull statistics is proposed for estimating the breakdown time of polymeric insulating materials with borax. ...
Household food security remains a challenge in South Africa. The national government instituted the Integrated Food Security Strategy (IFSS) programme which identifies household agricultural production as an important element of improving household-level food security. Agricultural extension is well positioned to help achieve this aim, but its current contribution is unknown. This study identif...
