Engineering aspects of magnetic film memories

Some of the more pertinent engineering aspects relating to the design of magnetic film destructive readout (DRO) memories are given, together with a brief reference to nondestructive readout memories. The technical discussion centers primarily on three major areas: 1) storage element characteristics such as skew, dispersion, disturb threshold, and magnetostriction, and how these relate to element fabrication and memory design; 2) memory plane design, with reference to primary effects of eddy currents, fringing fields, and sense line arrangements; 3) special circuit considerations as they relate to film memories. Much of the information presented is general enough to apply to various design approaches. However, specific examples and results obtained with production models of the FFM-202 memory system are used for purposes of illustration. A number of these 300-ns memories are now operating in the field, and current margins obtainable have been superior to those of coincident current core memories. DRO magnetic film memories are presently used in data processing equipment mainly as scratchpads, either as internal stores or as high-speed input/output buffers. However, the real impact of thin film units will be felt when they are commercially available as relatively large building-block modules in the range of 4096 words of 74 bits, at speeds of 200 to 400 ns and at costs competitive with one μs coincident current core memories. The present low costs of semiconductors have alleviated most of the disadvantages of word organization, particularly in magnetic films where only a relatively low-power, unipolar word pulse is needed. Also, the associated low drive power reduces heat dissipation and makes simpler a more compact modular design. This is needed to reduce logic delays in large capacity, high-speed systems. In order to obtain a large capacity, low-cost film memory, primary engineering problems involving the memory stack must be solved. As an example of one desirable approach, a plane design with increased bit density (which results in reduced costs per bit and shorter delays) is described, together with some preliminary results obtained.
Evaluation of the perspectives of balanced scorecard in m-commerce through the analytic network process

The development of research based on the implementation of the balanced scorecard (BSC) as a tool of management control in companies has become an important issue, which seeks to increase the management control, translating the vision and strategy into a coherent set of indicators performance. The breakthrough of the BSC is an increase in the quality and reliability in the implementation of the strategic objectives, which are made in accordance to each of the perspectives that manages the BSC. From a management point of view, this increases the safety and ease in the responses to the changes that occur in the sector in which the company operates. This paper discusses a methodology which seeks to prioritise the strategic objectives identified in each generic BSC perspective of mobile commerce which was initially made by the authors and reviewed by a peer group fully knowledgeable of the subject of e-commerce through the analytic network process. This research is an extension of previous work done by the authors in the case of e-commerce.
Homogenized and Heterogeneous Limit Analysis Model for Pushover Analysis of Ancient Masonry Walls with Irregular Texture

Two multi-step models for the pushover analysis of in-plane loaded historical masonry walls with irregular texture are presented. Both approaches are developed within an equivalent frame assumption. The first three-step model is a heuristic homogenization procedure in which the first step masonry is substituted with a macroscopic equivalent homogeneous material, with ultimate properties deduced from the solution of suitable boundary value problems on sample windows with different sizes. Masonry strength domains are evaluated through a limit analysis upper bound finite element (FE) approach. In the second step, ultimate bending moment-shear force strength domains of piers and spandrels are derived by means of a homogeneous upper bound FE limit analysis. In the last step, a frame model of an entire wall is assembled, where piers and spandrels are modeled as elastic-plastic Timoshenko beams with ultimate resistance evaluated using previous steps. The second approach is a two-step heterogeneous model, where piers and spandrels are analyzed through a FE limit analysis model, discretizing the walls “as they are”. To validate both approaches, a masonry wall arranged in irregular texture is studied in the inelastic range under increasing static loads. Results are compared with those obtained by a standard frame model and an expensive heterogeneous 2D FEM.
The Growth of the offer and the Perceptions of Television Content Quality

ABSTRACT This article examines the evolution of the attitudes of Spanish viewers to television from 2008 to 2016. This has been a period of time characterised by a substantial increase in the number of television channels. More specifically, the analysis is focused on audience satisfaction, perceptions of content quality and moral and pragmatic concerns. The data used in the empirical analysis come from three rounds of a survey conducted in 2008, 2012 and 2016. The size of the sample is 1,000 respondents for each year. The findings suggest that the attitudes to television have remained very stable in spite of the changes in the growth of the offer and technological upgrading.
Computer‐Aided Design of Metal Melt Filters: Geometric Modifications of Open‐Cell Foams, Effective Hydraulic Properties and Filtration Performance

The combination of additive manufacturing and replication technique enables the development of new ceramic foam filters (CFFs) for the filtration of metal melts based on computer‐generated templates. This article presents a numerical study on the sensitivity of filtration performance with respect to different geometric modifications, applied to an artificial monodisperse base structure. Three different geometric modifications are implemented, namely, elliptical elongation and flattening of the strut cross section with respect to the flow direction, additional finger‐like struts protruding into the pore cavity, and addition of deliberately closed windows. All modifications are implemented for overall porosities of 70–90%. The performance of the new structures is evaluated for continuous casting of aluminum by comparing the hydraulic tortuosity, the permeability, the Forchheimer coefficient, and the filtration coefficient, which are obtained from detailed pore‐scale simulations of the melt flow and inclusions transport using an Euler–Langrange approach. For the fast determination of the permeability coefficients, a novel and extremely simple model for the prediction of the Forchheimer coefficient is described. The investigation shows that geometric modifications to open‐cell foams potentially improve the filtration performance without significant decrease in filter porosity and can be considered as templates for the design of efficient CFFs.
Capacity calculations for rapidly fading communications channels

This paper derives the Shannon channel capacity-cost function for a class of randomly time-varying channels under an average power constraint. The channels considered can be characterized by a series of uncorrelated parallel diversity channels with Gaussian-distributed random gain and additive white Gaussian noise parameters. The resulting expression for the single-channel case clearly shows that such channels have finite capacity even when the source power is unconstrained. Extensions are made to the multiple-diversity-channel case with a modified "water-filling" problem resulting.
Optimal placement of mobile antenna in an urban area using evolutionary multiobjective optimization

The optimized placements of mobile antennas (MA) in an existing high traffic urban area are identified using evolutionary multiobjective optimization algorithms (EMOA). The design parameters such as (x, y) coordinates, transmitting power, height, and tilt are considered. The objectives are coverage and cost where as the inequality constraints are handover, traffic demand, and overlap. Modified NSGA‐II (MNSGA‐II) is preferred to improve the non dominated solutions. A detailed study is performed about physical and geometrical structure of propagation environment. Four different case studies are performed. The simulation results reveal that Hata–Okumura path loss model is more suited. MNSGA‐II is able to determine optimal MA parameters for multiobjective case studies. © 2012 Wiley Periodicals, Inc.

The bigger picture - capturing value creation for an engineering school as it initiates engineering education research

To help those introducing engineering education research in contexts where there is no existing tradition for this kind of research, this paper looks at an approach to value capture based on a learning community cultivation model developed by Etienne Wenger which uses a five cycle assessment framework. The framework captures the value of this type of research more comprehensively than more traditional indicators like research output and can be useful both for preparing return on investment reports for administrators and for planning new research projects. Here we exemplify its application for a 3-year nationally funded project and compare this approach with an alternative one.
Optimizing the performance of planar transformers

Planar transformers are a good solution for high frequency switching-mode power supplies (SMPS). Since these kind of transformers have some advantages that improve the SMPS performance, their use is growing. Some of the high frequency parasitics can be drastically reduced due to their planar geometry and the proximity of the windings. This work presents a study of different structures and winding strategies using a standard procedure to build planar transformers. This standard method makes easier and cheaper the transformer construction by means of a standard set of layers. The paper presents a study of the influence of the parasitic effects, the advantage of the interleaving technique depending on the magnetic component role, the advantage of these transformers in multiwinding applications and the use of planar transformers in different topologies. The study is carried out by means of a finite element analysis (FEA) procedure, not only by the inspection of the flux and current distribution, but generating models that take into account all the geometry and frequency effects. Design guidelines and some experimental results are also included in this paper.
A particle‐continuum coupling method for multiscale simulations of viscoelastic–viscoplastic amorphous glassy polymers

In this contribution, we present a partitioned‐domain method coupling a particle domain and a continuum domain for multiscale simulations of inelastic amorphous polymers under isothermal conditions. In the continuum domain, a viscoelastic–viscoplastic constitutive model calibrated from previous molecular dynamics (MD) simulations is employed to capture the inelastic properties of the polymer. Due to the material's rate‐dependence, a temporal coupling scheme is introduced. The influence of the time‐related parameters on the computational cost and accuracy is discussed. With appropriate parameters, multiscale simulations of glassy polystyrene under various loading conditions are implemented to showcase the method's capabilities to capture the mechanical behavior of polymers with different strain rates and with non‐affine deformations of the MD domain.
Accurate Delay Estimation for Multisensor Passive Locating Systems Exploiting the Cross-Correlation Between Signals Cross-Correlations

The availability of accurate estimates of the delay or time of arrival of the incoming signals is of paramount importance for the position estimation in passive radars with multiple receivers. This correspondence aims at improving estimation of the delays by multiple detectors exploiting the cross-correlation between the cross-correlation estimates (say cross-cross-correlation) of the received signals. The resulting equation system is formulated as a least squares minimization problem, whose solution is efficiently found computing the pseudoinverse of the model matrix. In fact, the cross-cross-correlation implicitly performs a filtering operation on the considered signal, approximating the generalized cross-correlator behavior, without using statistical information about the signal spectra. The proposed method is numerically validated in comparison with classic counterparts and theoretical bounds.
DERIVATION OF THE AUSTRALIAN AND NEW ZEALAND WATER QUALITY GUIDELINES FOR TOXICANTS

A new framework was developed and used to derive the Australian and New Zealand (ANZECC & ARMCANZ 2000) water quality guidelines for metal, inorganic and organic toxicants. This framework incorporates the principles of risk and recent advances in ecotoxicity modelling. As such, it is a significant advance on the previous ANZECC (1992) and other international water quality guidelines. Two different methods were used to derive the guidelines: a modification of the Canadian (CCME 1991) assessment factor method, and a new statistical distribution method called the Burr Type III method (Campbell et al. 2000) which was developed from the Aldenberg and Slob (1993) method. This paper provides the rules governing the framework, details of the collation and screening of the toxicity data and the methods used to derive the guidelines.

Tools for Design Management in Building Projects

Lean Construction philosophy is increasingly being used by construction companies to improve their production; however, in this industry, such applications are most frequently in the construction phase that in the design phase. The purpose of this paper is to propose the necessary and customised tools for applying Lean concepts to the building project design management. As a guide, this paper uses the steps recommended in the Project Definition and Lean Design phases, based on the Lean Project Delivery System TM. It adapts each module application and selects some tools regarded as the most appropriated. These tools have been gradually implemented in the authors’ office – same that design and execute building projects - with encouraging results. Application of such simple tools has helped us to eliminate wastes and prevent redesign. Good design management improves building project productivity and quality in other phases of the project; thus it benefits design and construction companies, as well as consumers who purchase these products. However, we consider that one of the biggest challenges is to align designers with these principles and commit these professionals to apply them.
Genome-Wide SNP Analysis Reveals Multiple Paternity in Burmese Pythons Invasive to the Greater Florida Everglades

Abstract. Reproductive strategies are an essential component of invasion ecology that influence invasion success and rates of population growth. Burmese Pythons (Python bivittatus) are large constrictor snakes that were introduced to the Greater Everglades Ecosystem of southern Florida, USA, from Asia. Since their introduction, these giant constrictors have spread throughout wetlands of southern Florida while increasing in abundance and causing declines in the native species upon which they prey. Multiple paternity in reproduction could facilitate invasion success by increasing the genetic diversity produced within each reproductive event. We used Diversity Arrays Technology genome-wide genotyping to assess multiple paternity in the progeny of wild Burmese Pythons in Florida. We analyzed >4,000 single nucleotide polymorphisms from 153 neonates belonging to 4 clutches collected in southwestern Florida. Complementary hierarchical and K-means clustering analyses of the genetic distances within clutches revealed that three clutches were each fertilized by two sires, with a fourth fertilized by a single sire. The proportions of offspring attributable to each sire within multiple paternity clutches ranged from nearly even to highly skewed. Analysis of multivariate dispersion showed significantly increased genetic variability in the multiple paternity clutches. These results improve our understanding of the reproductive strategy and invasion potential of a giant constrictor with significant ecological impacts.
Adaptive Contract Net Protocol Based on Ant Colony Optimization Algorithm

An adaptive contract net protocol which can adapt to dynamic environment is proposed based on ant colony optimization algorithm. In the negotiation process of task allocation, the probability of the contractor being selected is related with the contractor’s credibility and ability. Several experiments are performed to show the advantages of this algorithm, it has a better decision quality when task recurrence rate (TRR) unchanged, and the communication traffic (CT) remains at a low level as TRR increases when the number of tasks (NT) unchanged. As a result, the algorithm can enhance the decision quality and reduce the communication traffic.
Réduction du comportement myope dans le contrôle des FMS : une approche semi-hétérarchique basée sur la simulation-optimisation

Le controle heterarchique des systemes de production flexibles (FMS) preconise un controle peu complexe et hautement reactif supporte par des entites decisionnelles locales (DEs). En depit d'avancees prometteuses, ces architectures presentent un comportement myope car les DEs ont une visibilite informationnelle limitee sue les autres DEs, ce qui rend difficile la garantie d'une performance globale minimum. Cette these se concentre sur les approches permettant de reduire cette myopie. D'abord, une definition et une typologie de cette myopie dans les FMS sont proposees. Ensuite, nous proposons de traiter explicitement le comportement myope avec une architecture semi-heterarchique. Dans celle-ci, une entite decisionnelle globale (GDE) traite differents types de decisions myopes a l'aide des differentes techniques d'optimisation basee sur la simulation (SbO). De plus, les SbO peuvent adopter plusieurs roles, permettant de reduire le comportement myope de plusieurs facons. Il est egalement possible d'avoir plusieurs niveaux d'autonomie en appliquant differents modes d'interaction. Ainsi, notre approche accepte des configurations dans lesquelles certains comportements myopes sont reduits et d'autres sont acceptes. Notre approche a ete instanciee pour controler la cellule flexible AIP- PRIMECA de l'Universite de Valenciennes. Les resultats des simulations ont montre que l'architecture proposee peut reduire les comportements myopes en etablissant un equilibre entre la reactivite et la performance globale. Des experimentations reelles ont ete realisees sur la cellule AIP-PRIMECA pour des scenarios dynamiques et des resultats prometteurs ont ete obtenus.
A Case Study on the Air Flow Characteristics of the Hirobo-FALCON 505 Controllable Helicopter's Main Rotor Blade

The aerodynamics of the helicopter rotor is one of the most elating and exigent tribulations faced by the aerodynamicists today. Study through flow visualization process plays a key role in understanding the airflow distinctiveness and vortex interaction of the helicopter main rotor blade. Inspecting and scrutinizing the effects of wake vortices during operation is a great challenge and imperative in designing effective rotor system. This study aimed to visualize the main rotor airflow pattern of the Hirobo-FALCON 505 controllable subscale helicopter and seek for the vortex flow at the blade tip. The experimental qualitative data is correlated with quantitative data to perform scrupulous study on the airflow behavior and characteristics along with its distinctiveness spawned by the main rotor blade. Simulation using design software is performed in analogous stipulations to endow with comparability between the flow visualization results. Throughout the blade span several dissimilar flow patterns have been identified. The main rotor hub has turbulent flow at its center due to low energy of air amassed in this region whereas in the middle portion of the rotor blade, the air encompasses high kinetic energy with a clear straight streamline pattern.

Discrete simulation of colored noise and stochastic processes and 1/fα power law noise generation

This paper discusses techniques for generating digital sequences of noise which simulate processes with certain known properties or describing equations. Part I of the paper presents a review of stochastic processes and spectral estimation (with some new results) and a tutorial on simulating continuous noise processes with a known autospectral density or autocorrelation function. In defining these techniques for computer generating sequences, it also defines the necessary accuracy criteria. These methods are compared to some of the common techniques for noise generation and the problems, or advantages, of each are discussed. Finally, Part I presents results on simulating stochastic differential equations. A Runge-Kutta (RK) method is presented for numerically solving these equations. Part II of the paper discusses power law, or 1/f/sup /spl alpha//, noises. Such noise processes occur frequently in nature and, in many cases, with nonintegral values for /spl alpha/. A review of 1/f noises in devices and systems is followed by a discussion of the most common continuous 1/f noise models. The paper then presents a new digital model for power law noises. This model allows for very accurate and efficient computer generation of 1/f/sup /spl alpha// noises for any /spl alpha/. Many of the statistical properties of this model are discussed and compared to the previous continuous models. Lastly, a number of approximate techniques for generating power law noises are presented for rapid or real time simulation. >
