The DE magnetometer preprocessor users guide

A users guide for the Dynamics Explorer magnetometer preprocessor computer program is provided. This program is written in Xerox Extended FORTRAN IV and is used to process telemetry data in order to provide data files for use in analysis programs. This preprocessor is designed to operate on the Sigma 9 and the IBM 4341

Efficient calibration for high-dimensional computer model output using basis methods

Calibration of expensive computer models with high-dimensional output fields can be approached via history matching. If the entire output field is matched, with patterns or correlations between locations or time points represented, calculating the distance metric between observational data and model output for a single input setting requires a time intensive inversion of a high-dimensional matrix. By using a low-dimensional basis representation rather than emulating each output individually, we define a metric in the reduced space that allows the implausibility for the field to be calculated efficiently, with only small matrix inversions required, using projection that is consistent with the variance specifications in the implausibility. We show that projection using the $L_2$ norm can result in different conclusions, with the ordering of points not maintained on the basis, with implications for both history matching and probabilistic methods. We demonstrate the scalability of our method through history matching of the Canadian atmosphere model, CanAM4, comparing basis methods to emulation of each output individually, showing that the basis approach can be more accurate, whilst also being more efficient

Indoor Positioning Techniques Based on Wireless LAN

As well as delivering high speed internet, Wireless LAN (WLAN) can be used as an effective indoor positioning system. It is competitive in terms of both accuracy and cost compared to similar systems. To date, several signal strength based techniques have been proposed. Researchers at the University of New South Wales (UNSW) have developed several innovative implementations of WLAN positioning systems. This paper describes the techniques used and details the experimental results of the research

The Relationship Between the Number of Shots and the Quality of Gamma Knife Radiosurgeries

Radiosurgery is a non-invasive alternative to brain surgery that uses a single focused application of high radiation to destroy intracerebral target tissues. A Gamma Knife delivers such treatments by using 201 cylindrically collimated cobalt-60 sources that are arranged in a hemispherical pattern and aimed to a common focal point. The accumulation of radiation at the focal point, called a \shot due to the spherical nature of the dose distribution, is used to ablate (or destroy) target tissue in the brain. If the target is small and spherical, it is easily treated by choosing one of four available collimators (4, 8, 14, or 18 mm). For large, irregular targets, multiple shots are typically required to treat the entire lesion, and the process of determining the optimal arrangement and number of shots is complex. In this research, fast simulated annealing and a novel objective function are used to investigate the relationship between the number of shots and the quality of the resulting treatment. Sets of 5, 10, 25, 50, and an unrestricted number of shots are studied for an arteriovenous malformation (AVM). As the shot limit increases the following improvements in plan quality are observed: the conformity of the prescription isodose line increases, the lesion dose becomes more homogeneous, and an increase use of smaller collimators to deposit dose. Large improvements in plan quality are realized by increasing the number of shots from 5 to 50, and to achieve a similar magnitude of improvement past 50 requires an increase over 1500 shots for the complex lesion investigated. This observation suggests that it is clinically valuable to improve the Gamma Knife\u27s delivery capabilities so that 50 shot treatments are possible

Dual networking: how collaborators network in their quest for innovation

Organizations typically employ a division of labor between specialist creator roles and generalist business roles in a bid to orchestrate innovation. This paperseeksto determine the extent to which individuals dividing the work across roles canalso benefit from dividing their network.We argue that collaborating individuals benefit from connecting to the same groups but different individuals—an approach we label dual networking—rather than from a pure divide-and-conquer approach. To test this argument, weexploit a unique feature of a dual career-ladder setting in a large multinational where R&D managers and technologists partner up in their quest forinnovation. We propose—and find—thatcollaborators who engage in dual networkingattain an innovationperformance advantage over those who connect to distinctgroups. This advantage stems from the opportunity to engage in dual interpretation and dual influencing, leading to more effective elaboration and championing of innovative ideas. In demonstrating these effects, the paper advances understanding of how collaborators organize their networking activities to best achieve innovative outcomes

The relative value of the division versus duplication of network ties for innovation performance

Exploiting a unique setting of R&D technologists and managers in a large multinational who are “partnered-up” in their pursuit of innovation, this paper explores under what circumstances technologists and managers benefit from duplicating network ties to the same groups in the organization as their partner, or from dividing the network with their partner by each interacting with different groups. Introducing the concept of network duplication – the extent to which two individuals are tied to the same functional groups inside an organization – this paper aims to build and test a theory of the division versus duplication of networks. It advances our understanding of second-order social capital and its role in the interpretation and influencing aspects of the innovation process by shedding light on how network duplication affects technologists’ and managers’ innovation performance. It finds that the merits of a division versus duplication-of- networks approach are contingent on the mutual interdependence of managers and technologists

The Development of a Comprehensive Mechanism for Intracellular Calcium Oscillations: A Theoretical Approach and an Experimental Validation

Calcium is an important second messenger for cellular communication. Theoretical models help scientists understand its signalling mechanism. A comprehensive model was developed in order to minimize any limitations in the models currently presented in the literature. Experimental results support the model and therefore the theoretical model provides a plausible explanation of the dynamics of the calcium-signaling mechanism. In the future, additional verification will be performed using various experimental configurations on PC12 cells. Further, the model will be used to predict the response of cells to environmental factors such as pesticides and heavy metals
