O Movimento da Matemática Moderna: Repercussão na abordagem no Brasil do conceito de função nos livros didáticos das décadas de 1950 a 1970.
… aims to examine the approach of the concept of mathematical function as presented by four collections of textbooks, pointing out how the Modern Mathematics Movement impacted on their methodological structures. Initially, we present an outline of the history of the emergence of the concept of …

Möbius: for Orchestra
… becomes more of an A-B-(A'+B'). Much like the mathematical function this piece is named after – a loop whose ending is never identical to its beginning and whose mirror-image lacks symmetry – the listener is brought to a new ending with familiar, non-repeated material. Many times throughout the …

Mechanical behaviour of adhesive anchors installed in concrete
… vary linearly with it. Based upon this, a simple mathematical function can be determined, which allows the calculation of the displacement of any adhesive anchor. This can be used as a design criterion for the, limit state of serviceability of the particular system.

Multifractal analysis of heart rate variability using wavelet-transform modulus-maxima method
… singularities (a point in time series where a mathematical function is not differentiable). For monofractal signals, the output of a system contains the same type of singularities regardless of the initial condition, while multifractal signals generate outputs with different fractal properties …

Cross-correlation based performance measures for characterizing the influence of in-vehicle interfaces on driving and cognitive workload
… two new performance measures inspired by the mathematical function of cross-correlation: one which evaluates the cumulative effect and the other which evaluates the effects of individual instances of in-vehicle interactions on driving and cognitive load. The results from three driving …

Cerebral spasticity modeled as disorded equilibrium point control
… coefficient, relative stiffness coefficient and mathematical function which can act as an approximation CNS the virtual trajectory described in the EPH. This research produced a model of passive motion with the ability to produce parameter values that not only differentiate subjects with …

Investigation of an integrated regional environmental watershed methodology
… of the water flow in streams by a mathematical function expressed through the hydrograph. The investigation explores the hydrograph and proposes that it can be constructed from hydrological components in a feedback concept with precipitation as input and the volume of flow as …

Quantitative super-resolution imaging of cell polarity proteins using DNA-PAINT
… of proteins is crucial for understanding their function. The development of super-resolution imaging has improved our ability to garner this information, but counting individual molecules in densely-packed assemblies is still challenging. DNA-based point accumulation for imaging in nanoscale …

Hybrid probabilistic broadcast schemes for mobile ad hoc networks
… a node based on its local node density using a mathematical function. Thus, a node located in a sparse region of the network is assigned a high forwarding probability while a node located in denser region is assigned a relatively lower forwarding probability. These combined effects enhance …

Identification of potential groundwater recharge zones: a case study of KwaZulu-Natal, South Africa
… principle according to the model type and mathematical function encompassed by the model. Once they were normalized the highest mean value of the parameters were assigned the highest factor weight, whilst the lowest mean value was assigned the lowest factor weight. The delineated …

Geomagnetic Compensation for Low-Cost Crash Avoidance Project
… characterized the local geomagnetic field with a mathematical function from field calibration data. The GPS heading was used as the input and the output is the voltage level of the Earth’s magnetic field. The second algorithm, Compensation Scheme 1.5, used a mathematical model of the Earth’s …

ELASTOCALORIC EFFECTS IN POLYMERS
… the model were done here via the addition of a mathematical function that reflects the changes in crystallisation with time. This improvement led to a better reproduction of the relevant processes behind the large elastocaloric effects seen in natural rubber. The newly modified model showed much …

Extreme weather disaster resilient port and waterway infrastructure for sustainable global supply chain
… the operating conditions of a seaport. A mathematical function to estimate LOS level (A, B, C, D, E, F) was proposed based on delay time and waiting time of cargo vessels at the port and number of processed cargo vessels per total annual cargo vessels. A new methodology was developed to …

Active Source Management to Maintain High Efficiency in Resonant Conversion over Wide Load Range
… is controlled by phase-shifting the switching functions of the pre-regulator and inverter. The pre-regulator reduces the dc current in the input inductors, which is a main contributor to current stress and conduction losses in the inverter switches. Total loss of the inverter switches is …
