New and improved : Linda in Java

This paper discusses the current resurgence of interest in the Linda coordination language for parallel and distributed programming. Particularly in the Java field, there have been a number of developments over the past few years. These developments are summarised together with the advantages of using Linda for programming concurrent systems. Some problems with the basic Linda approach are also discussed and a novel solution to these is presented. The power and flexibility of the proposed extensions to the Linda programming model are illustrated by considering a number of example applications, including a detailed case study of visual language parsing

Resource‐based learning strategies: Implications for students and institutions

This paper reports some findings from a project in implementing resource‐based learning in economics, and identifies some implications for students and institutions. These include student responses to a mid‐semester evaluation and the views of the project team. The latter have been informed by action research which sought to recognize students’ individual differences, employ active learning methods and, above all, integrate IT into the curriculum. While innovative strategies are clearly welcomed, students show strong attachment to some traditional methods. Most of those who suggested changes to the range of activities asked for reinstatement of at least some lectures, generally as additions to existing activities. Implications include the need for students and staff to acquire a wide range of new skills, for large‐scale curriculum review if new learning technologies are to be fully integrated, and the need to acknowledge that, given student and staff perceptions of change, the process may be long and costly

Timing Control System

A timing control system is disclosed which is particularly useful in connection with simulated mortar shells. Special circuitry is provided to assure that the shell does not over shoot, but rather detonates early in case of an improper condition; this ensures that ground personnel will not be harmed by a delayed detonation. The system responds to an externally applied frequency control code which is configured to avoid any confusion between different control modes. A premature detonation routine is entered in case an improper time-setting signal is entered, or if the shell is launched before completion of the time-setting sequence. Special provisions are also made for very early launch situations and improper detonator connections. An alternate abort mode is provided to discharge the internal power supply without a detonation in a manner that can be externally monitored, thereby providing a mechanism for non-destructive testing. The abort mode also accelerates the timing function for rapid testing

Contributions To The Estimation Of The Logit, Log Odds And Common Odds Ratio

Asymptotic series expansions for the bias and mean square error of the logit estimator are developed. In addition, an estimator of the bias and asymptotic series for the expectation of this estimator and the estimator of the mean square error are derived. These formulations have been expressed in such a way that general coefficients can be calculated and then implemented for any choice of the parameters involved in the logit estimation problem. The formulas developed are applied, providing similar asymptotic series, for the estimation of the log odds ratio.;A general method for the linear combination of estimators is proposed. This procedure is applied to combine log odds ratios and new estimators are developed for the estimation of a common odds ratio. The small sample properties of these estimators and some widely used estimators are examined and compared in a Monte Carlo simulation. Since no one estimator is uniformly the best, a scheme for applying the most appropriate estimator in a given situation is proposed. Illustrations of settings in which this approach is feasible are examined

Removing Physical Presence Requirements for a Remote and Automated World - API Controlled Patch Panel for Conformance Testing

Quality assurance test engineers at the UNH-InterOperability Lab must run tests that require driving and monitoring a selection of DC signals. While the number of signals is numerous, there are limited ports on the test equipment, and only a few signals need patching for any given test. The selection of signals may vary between the 209 different tests and must be re-routed frequently. Currently, testers must leave their desk to manually modify the test setup in another room. This posed a considerable issue at the onset of the COVID-19 Pandemic when physical access was not possible. In order to enable future remote testing and human-free automation, there is a need for a remote patching device. Such a device was designed, constructed, and deployed. The process of designing the product involved defining design constraints, developing conceptual designs, selecting components and generating an electrical schematic, prototyping and iterating PCB versions, and final deployment and testing of the product

Growth and Defect Formation in Graphene

In this work, few-layer graphene (FLG) was grown from SiC(0001) with temperature, growth time and cooling rate as variables. Samples were characterised by Scanning Tunnelling Microscopy (STM), Low Energy Electron Diraction (LEED), Auger Electron Spectroscopy (AES) and Raman Spectroscopy (RS) to determine graphene quality. The information obtained from these techniques was then used to determine optimal conditions for growing graphene from SiC(0001). Contamination on graphene lms is also discussed and a facile method for the removal of large scale metal contaminant layers from the surface is described. To study adhesion of FLG to a substrate, a continuum energy model was developed to obtain the adhesion energy via the measurement of pleat defects by STM. This model was applied to graphene grown from SiC(0001) and its adhesion energy was found to be signicantly larger than the those measured for graphene on other substrates. Variation of pleat defects on graphene grown from SiC(0001) with dierent growth parameters was also studied by STM. The factors that aect the dimensions and concentration of pleats were determined and discussed in relation to the quality of the lm. Further investigation was conducted on the stability of pleat defects under STM imaging, with the presence of contamination and defects found to have a signicant eect in reducing the dragging of pleats by the probe tip. A comparative study of the dynamics of extrinsic defects on FLG and graphite is also presented in this work. Samples were bombarded with 0.2 keV Ar+ ions, heated to dierent temperatures and studied with STM. The concentration, mobility, agglomeration and alignment of defects was examined and mechanisms suggested for the behaviour observed. The Local Density of States (LDOS) at defect sites of both graphite and FLG were studied by Scanning Tunnelling Spectroscopy (STS) to determine if signicant dierences in electronic structure due to defects were observed between the two systems. Preliminary experiments to optimise the growth of graphene on Cu substrates by \hot-wall" and \cold-wall" methods have been performed, to determine whether cold-wall growth presents a viable alternative to hot-wall for the production of high quality graphene. Graphene was grown by both methods using dierent growth periods to determine the optimal growth time for each method. The use of evaporated Cu on SiO2 as growth substrates is also discussed. Samples produced by both methods were studied by Scanning Electron Microscopy (SEM) to determine their quality. Electron Back-Scatter Diraction (EBSD) measurements were also performed on samples produced by both methods to determine the extent to which Cu grain orientation aects the growth of graphene

The Holy Spirit and knowledge of God: a study in the theology of Karl Barth

As the title Indicates, the objective of this essay Is to study the doctrines of the Holy Spirit and the Knowledge of God in juxtaposition to one another. It is also a study in the theology of Karl Earth, That is, it is hoped that through an intensive study of his handling of these two doctrines one might catch a glimpse of his theology as a whole. The doctrine of the Holy Spirit lends Itself admirably to this objective in that it relates so essentially to almost every other Christian doctrine. It is through the Holy Spirit that Jesus Christ relates to men. Therefore, it is impossible to speak of the Holy Spirit with any thoroughness without becoming involved in the doctrine of the Incarnation and the doctrine of man, and several of their corollaries? Holy Scripture, proclamation, analogy, the Church, as well as election, creation, sin, reconciliation, eschatology, and so on. Similarly, the question of the knowledge of God touches on all of these major areas of theological inquiry. These two doctrines, therefore, lend themselves especially well to a view of the systematlc, coherent wholeness of Berth's thought.Two main themes run throughout this essay. One is the inseparability of revelation and reconciliation, or of epistemology and soterlology. This is a result of Earth's Chrlstocentrism, and his insistence that Chrlstology must be applied to theological epistemology as well as to every other doctrine, i.e., his rejection of natural theology. Earth*s doctrine of the work of the Holy Spirit as Reconciler as well as Revealer is therefore a central and all pervading theme. The other is the inseparability of the Word and Spirit. One might say that this essay is essentially about nothing else than the Spirit as the power of the Word, whereby man's knowledge of God is achieved.It is impossible to appreciate the significance of Karl Barth without taking account of his polemic against various other theological points of view. I have therefore made some effort to understand his opponents, especially in the field of eplstemology. Similarly, it is important to know something of the positive influence of other men upon him. Both his friends and his "enemies", if they may he so called, are often dealt with as well in the footnotes.CHAPTER ONE deals with the Word made flesh as the basis of the knowledge of God: (a) Earth's epistemology as a posteriori, form and method being determined by content: tneology as science. (b) The theological "object of knowledge as the Incarnation, i.e., the life, death and resurrection of Jesus Christ; the divinity of Christ as His revelation of the Father. (c) Other starting-points are discussed and Barth's comments upon them are noted: Augustine and some of his contemporary followers; the roots of modernist theology in modern philosophy, beginning with Descartes and Kant and traced through Schleiermacher and Feuerbach to Bultmann; Thomas Aquinas and the Thomist tradition. (d) Barth's concept of "religion" as it relates to the knowledge of God.CHAPTER TWO deals with the relation of Jesus Christ and the Holy Spirit, noting Barth's exegetical comments on the relevant Biblical passages: (a) The relation of the Spirit to eschatology in the Old Testament seen as the basis of the Synoptic conception of the relation of Christ and Spirit. (b) The relation of the Spirit to Christ as seen in the Gospel stories of the virgin birth, baptism of Christ, temptation, miracles, death and resurrection of Christ; the Spirit as witness to Christ in John and Paul; the Holy Spirit as parousia of Christ. (c) The Holy Spirit in the Trinity: Sx Patre Filioque.CHAPTER THREE deals with the relation of the Holy Spirit to man as the knower of God: (a) Anthropology based on Christology; the image of God in man as it relates to the knowledge of God; the Creator Spirit and man's spirit; election, creation and redemption in Christ. (b) Man's sin as pride and sloth; his refusal to know God; sin and the image of God; sin as falsehood; the sin against the Holy Spirit. (c) The Spirit the Reconciler as Revealer of Christ; Earth's attack on Augustine's synergism; slmul peecator et .justus; justification and sanctification: union with Christ by the Spirit; the relation of revelation and reconciliation and the prophetic work of Christ through the Spirit; the question of universal!am.CHAPTER FOUR deals with the character of theological knowledge as faith considered in relation to (a) Theological language and the doctrine of analogy; Earth compared with Thomas Aquinas, A. Quenstedt; analogla fldel, and the opposition to analog!a entls; Barth's concept of analogla relationis. (b) Proclamation and Holy Scripture; Scripture as Word of God, as witness to revelation, as inspired by the Holy Spirit; the authority of Scripture for proclamation; the problem of the canon. (c) Faith and Life in the Church as initiated by the call of Christ; the Spirit of the Word as the power of illumination and awakening; faith and experience; faith as acknowledgement, recognition, trust, confession; the life of faith as life in the Spirit; faith, love and hope; the Church as gathered, upbuilt, and sent by the Spirit; the Church as the community of the knowledge of God. (d) The Hope of Perfect Knowledge; perfect union with Christ In the Spirit, and the participation in God's knowledge of Himself

Letter from George Wells to James B. Finley

George Wells [son of Wellsville founder William Wells] invites Finley to visit and preach in Wellsville. He remembers Finley staying with his family while riding the circuit. Wells argues that there has been a great departure from the simplicity of the gospel on the Western Reserve, naming the doctrine of infidelity as preached by O\u27Kelley and abolitionism as preached by Giddings, for leading many men to ruin. Wells believes it would be extremely helpful to have an old time church planter like Finley in the pulpit once again to counter these teachings.
