Microprocessor-Based Data Acquisition and Control Software for Plant Growth Chambers (Spar System)

ABSTRACT COMPUTER software has been developed for a microprocessor-based data acquisition and control system to measure 64 transducers and to maintain closed loop environmental control for three sunlit Soil-Plant-Atmosphere Research (SPAR) units at Florence, SC. An assembly language program and a BASIC program were written to run concurrently by using a real-time inter-rupt. The assembly language program performs the data acquisition, real-time control, and time keeping. The BASIC program performs the dynamic signal condition-ing, the computation of control parameters, and the con-version and output of the acquired data in engineering units. Environmental control algorithms were im-plemented in software to control temperature, C02 con-centration, and relative humidity. The BASIC program utilizes the history of the absolute deviation from the control levels to compute the control parameters for the assembly language program to implement. The temperature control algorithm enabled control within ± 0.5 °C for control temperatures ranging from 15 °C to 35 °C with ambient temperatures ranging from 4 °C to 32 °C. A proportional control algorithm written in BASIC enabled C02 control for three SPAR units within ± 10 mg/L under changing radiation load with full canopy closure using one infrared gas analyzer. A C02 control algorithm using light response curves is derived to pro-ject C02 uptake and absolute deviations from the control level to correct the coefficients of light response curves. Dynamic environmental control of the SPAR units, which involves process feedback influenced by random climatic variations, can be obtained using an inexpensive microprocessor-based system. This enables researchers to conduct precise experiments involving climatic variables to provide the necessary inputs for crop simula-tion modeling.
Aligning Business and IT: The Process-Driven Architecture Model

Due to the fact that the corporate IT function is tightly coupled to enterprise processes and organization, today's IT is driven by the same dynamics as the enterprise itself. Based on this observation a four-layer process-driven architecture (PDA) model is derived which explicitly addresses current business and IT issues alike. The applicability of the model is demonstrated on both the descriptive and the prescriptive level of a theory
Multi-channel manufacturing with compatible machines

Multi-channel manufacturing (MCM) is a noteworthy approach offered as a kind of fractal manufacturing. Here cells are organised as channels. Machines are lined up to facilitate streamlined materials flow. Their replication in individual and separate channels is allowed. The machines are grouped in such a way to form channels that any product is prone to be produced at least in one channel. In addition, important parts are subject to production in more channels to prevent congestion. On the other hand, one-to-one association of operations to machines as in classical grouping techniques seems very restrictive. In fact any machine is capable of fulfilling more then one kind of task, and any operation is possibly accomplished in more than one kind of machine. In other words, compatible machines should not be overlooked. In this study, enhancing of MCM with compatible machines is aimed. Numerical experience has proved the superiority of the proposed method to form manufacturing cells.
Optimization of schedule robustness and stability under random machine breakdowns and processing time variability

In practice, scheduling systems are subject to considerable uncertainty in highly dynamic operating environments. The ability to cope with uncertainty in the scheduling process is becoming an increasingly important issue. This paper takes a proactive scheduling approach to study scheduling problems with two sources of uncertainty: processing time variability and machine breakdowns. Two robustness (expected total flow time and expected total tardiness) and three stability (the sum of the squared and absolute differences of the job completion times and the sum of the variances of the realized completion times) measures are defined. Special cases for which the measures can be easily optimized are identified. A dominance rule and two lower bounds for one of the robustness measures are developed and subseqently used in a branch-and-bound algorithm to solve the problem exactly. A beam search heuristic is also proposed to solve large problems for all five measures. The computational results show that the beam search heuristic is capable of generating robust schedules with little average deviation from the optimal objective function value (obtained via the branch-and-bound algorithm) and it performs significantly better than a number of heuristics available in the literature for all five measures.

Attenuation correction of myocardial perfusion scintigraphy images without transmission scanning

Attenuation correction is essential for reliable interpretation of emission tomography; however the use of transmission measurements to generate attenuation maps is limited by availability of equipment and potential mismatches between the transmission and emission measurements. This work investigates the possibility of estimating an attenuation map using measured scatter data without a transmission scan. A scatter model has been developed that predicts the distribution of photons which have been scattered once. The scatter model has been used as the basis of a maximum likelihood gradient ascent method (SMLGA) to estimate an attenuation map from measured scatter data. The SMLGA algorithm has been combined with an existing algorithm using photopeak data to estimate an attenuation map (MLAA) in order to obtain a more accurate attenuation map than using either algorithm alone. Iterations of the SMLGA-MLAA algorithm are alternated with iterations of the MLEM algorithm to estimate the activity distribution. Initial tests of the algorithm were performed in 2 dimensions using idealised data before extension to 3 dimensions. The basic algorithm has been tested in 3 dimensions using projection data simulated using a Monte Carlo simulator with software phantoms. All soft tissues within the body have similar attenuation characteristics and so only a small number of different values are normally present. A Level-Set technique to restrict the attenuation map to a piecewise constant function has therefore been investigated as a potential way to improve the quality of the reconstructed attenuation map. The basic SMLGA-MLAA algorithm contains a number of assumptions; the effect of these has been investigated and the model extended to include the effect of photons which are scattered more than once and scatter correction of the photopeak. The effect of different phantom shapes and activity distributions has been assessed and the final algorithm tested using data acquired using a physical phantom.
Preattentive Processing in Visual Search

Visual search is fundamental to many tasks that human operators perform in conjunction with engineered systems. Some obvious examples include industrial inspection, acquisition of information from aviation and weapon systems displays, and interaction with general purpose computer displays. Ease of visual search is a fundamental consideration in the design of computer-based menus and iconic displays (e.g., Andre and Wickens, 1991). Visual search efficiency affects performance variables such as the ease with which an interface or a piece of software can be learned, the time required to complete tasks, and user satisfaction. In weapon systems, visual search affects the probability of target detection, the time until detection, and the range at which detection occurs. These parameters can be critical for combat survival and mission effectiveness.
Cartographie fine de la recombinaison, analyse des séquences locales et étude du déséquilibre de liaison chez le blé tendre (Triticum aestivum)

Mieux connaitre les facteurs qui gouvernent l’apparition des evenements de recombinaison (crossing-overs ; CO) chez le ble tendre (Triticum aestivum L.) est primordial car ce processus est l’outil principal du selectionneur pour permettre le brassage de la diversite genetique et l’introgression de regions d’interet dans des varietes agronomiques. L’utilisation de techniques de cytogenetique developpees sur l’orge a permis de comparer la mise en place de la synapse lors de la meiose chez des lignees de ble tendre deletees de tout ou partie du bras long du chromosome 3B et qui avaient ete prealablement montrees comme presentant un nombre de chiasmas reduit par rapport a la variete euploide. Les analyses cytogenetiques couplees a des etudes bioinformatiques de la sequence montrent que le synapsis a lieu quasiment normalement chez les mutants et que la deletion de certains genes connus comme impactant le deroulement de la meiose pourrait expliquer le phenotype observe. De plus, le developpement de ressources genomiques (SNP, sequence) a destination des selectionneurs a permis la realisation de cartes genetiques haute densite des 21 chromosomes ancrees sur la sequence du genome. Tous les chromosomes montrent le meme profil de recombinaison avec un accroissement dans les parties distales et une reduction drastique dans les parties centromeriques et peri-centromeriques. L’exploitation de plus de 250 CO localises dans des fenetres de moins de 25 kb sur le chromosome 3B utilise comme modele pour l’etude de l’impact de la sequence sur la recombinaison, montre que les profils de recombinaison ancestrale et actuelle sont conserves et que les CO ont lieu preferentiellement dans les parties promotrices des genes exprimes en meiose ce qui suggere que la conformation chromatinienne influence la recombinaison. Finalement, ces donnees ont aussi ete l’opportunite de detecter des motifs lies a la recombinaison qui presentent des similarites avec celui cible par la proteine PRDM9 qui conduit a la recombinaison chez l’humain. Cela suggere que les mecanismes de controle de la recombinaison sont conserves chez les eucaryotes.

The Impact of Training Method on Skill Acquisition and Transfer

Technology, such as simulations and virtual reality (VR), can be used for training students and employees. Using these tools may have implications for skills development and retention, specifically related to individual differences and technology’s effectiveness as a learning tool. To explore this issue, a pilot study was used to evaluate how an individual’s performance on a task (i.e., the building an electrical circuit), differs depending on the physical fidelity of the learning environment. In addition, this study examined the effects of cognitive ability and goal orientation on task performance. Specifically this study investigated different methods for practicing the building of electrical circuits using a 2D breadboard simulation, a 3D virtual breadboard, and a physical breadboard. The preliminary results of this pilot study found that physical fidelity of learning environment was a significant predictor of construction time and circuit accuracy. Cognitive ability and learning goal orientation were significant predictors of gain scores and diagram accuracy.

The Function of Discourse Particles: A Study with Special Reference to Spoken Standard French

This monograph aims to contribute to linguistic knowledge about the distribution and function of discourse particles, particularly with respect to a small group of particles which are highly frequent in contemporary spoken standard French. The book is divided into two parts. Part 1 (Theory) defines discourse particles as such, and gives a dynamic global approach to their description. Matters such as previous research on discourse particles, related categories of particles, instructional semantics, the difference between speech and writing, the delimitation of discourse units, competing approaches to discourse structure and to coherence, and methodology are discussed extensively. Part 2 (Description) offers in-depth corpus-based analyses of six French discourse particles, namely bon, ben, eh bien, puis, donc , and alors , as used in non-elicted native-speaker interaction. The book is of interest to linguists doing research in semantics, pragmatics and discourse studies.
Aspect-Oriented Modeling Approaches and Aspect Code Generation

The integration of aspect oriented modeling approaches with model-driven engineering process achieved through their direct transformation into aspect-oriented code can enhance the software development from many perspectives. However, since no aspect modeling technique has been adopted as the standard so far, it becomes imperative to compare all existing techniques on the basis of some appropriate criteria. This study aims to assess existing UML-based aspect-oriented modeling techniques from the perspective of their suitability with regards to integration into model-driven engineering process through aspect-oriented code generation. For this purpose, an evaluation framework has been defined and employed to evaluate 14 well-published, UML-based aspect-oriented modeling approaches. Results of this comparison show that a majority of these approaches works well to handle the basic modeling tasks. However, in the context of their integration into model-driven engineering process, these approaches need to be improved from various perspectives.

Solving planar systems of equations on distributed-memory multiprocessors

The advent of VLSI has made extremely powerful, cost effective parallel computing systems practical. This has been accompanied by a tremendous increase in the demand for computing power as ever more complicated phenomena are being studied by numerical techniques. Unfortunately, the software developed over the last thirty years for solving these problems has been geared toward sequential or vector machines and is not directly applicable to the emerging highly concurrent computers. To address this problem, both direct and iterative sparse solvers have been developed for large scale, message passing multiprocessors. A new distributed multifrontal (DMF) algorithm for sparse Gaussian elimination on parallel computers is presented. This method uses the nested dissection reordering heuristic to extract separators from the graph of the matrix, thereby partitioning the matrix into disjoint blocks that can be allocated to the processors. Symbolic decomposition of the resulting matrix is shown to be completely independent. The number of messages exchanged during the sparse matrix factorization is limited to a function of the length of the separators and the DMF sparse solver achieves parallel efficiencies of over 70%. To address the computational bottleneck in an application program, the DMF sparse solver is coupled with a perfectly parallel sparse matrix assembly operation and embedded into PISCES, a 2-D device simulator developed at Stanford. Overall speedups of 8.1 are demonstrated using a 16-node hypercube multiprocessor. Symmetric positive definite systems can often be solved faster using iterative techniques. Therefore, a parallel implementation of one of the most successful iterative methods, the Incomplete Cholesky Preconditioned Conjugate Gradient (ICCG) algorithm, has been implemented. It also utilizes a nested dissection reordering and is designed to limit the volume of interprocessor communication. The ICCG sparse solver, which incorporates efficient triangular solution, matrix vector multiplication, and inner product routines, has demonstrated parallel efficiencies of over 80%. This algorithm is employed by a 3-D Poisson solver that achieves speedups of 9.8 on a 16 processor hypercube.
Structure of the Global Nanoscience and Nanotechnology Research Literature

Abstract : Text mining was used to extract technical intelligence from the open source global nanotechnology and nanoscience research literature. An extensive nanotechnology/ nanoscience-focused query was applied to the Science Citation Index/ Social Science Citation Index (SCI/ SSCI) databases. The nanotechnology/ nanoscience research literature technical structure (taxonomy) was obtained using computational linguistics, document clustering, and factor analysis. The nanotechnology/ nanoscience research literature infrastructure (prolific authors, key journals/ institutions/ countries, most cited authors/ journals/ documents) for each of the clusters generated by the document clustering algorithm was obtained using bibliometrics. Another novel addition was the use of phrase auto-correlation maps to show technical thrust areas based on phrase co-occurrence in Abstracts, and the use of phrase-phrase cross-correlation maps to show technical thrust areas based on phrase relations due to the sharing of common co-occurring phrases. The use of factor matrices quantified further the strength of the linkages among institutions and among countries, and validated the copublishing networks shown graphically on the maps. The ~400 most cited nanotechnology papers since 1991 were grouped, and their characteristics generated. Whereas the main analysis provided technical thrusts of all nanotechnology papers retrieved, analysis of the most cited papers allowed their unique characteristics to be displayed.
