Object-Oriented System Design (1992)

The reason for a different approach to systems analysis and designed is explained in cases where an objectoriented approach is to be taken to application programming. The paradigm of the object-oriented approach is shown to be a generalization of the paradigm used in the traditional approach to application software design. A new object-oriented approach to systems analysis and design is defined and illustrated. The design of an accounts receivable system is used to illustrate the methodology. The object-oriented approach described divides the work into three phases. In the first phase, the application is defined in terms of the entity types and relationships to be included in the system. In the second phase, the business objects to be simulated are identified and categorized as permanent, event, or dependent business objects. In the third phase, the program modules for each business object are specified. A message flow diagramming technique is defined and illustrated that has proven useful in specifying the programs required for business event object classes. The need is pointed out for action diagrams to define processing logic for customized program modules if a CASE tool is to be used to generate the code. The fact that this approach does not use data flow diagrams is noted. Message flow diagrams take the place of data flow diagrams in providing an overview of the system.Request access from your librarian to read this article's full text.
Analysis of the Massive Salt Fall in Big Hill Cavern 103 (2003)

This report summarizes recent reviews, observations, and analyses believed to be imperative to our understanding of the recent two million cubic feet salt fall event in Big Hill Cavern 103, one of the caverns of the Strategic Petroleum Reserve (SPR). The fall was the result of one or more stress driven mechanical instabilities, the origins of which are discussed in the report. The work has lead to important conclusions concerning the engineering and operations of the caverns at Big Hill. Specifically, Big Hill, being the youngest SPR site, was subjected to state-of-the-art solutioning methods to develop nominally well-formed, right-circular cylindrical caverns. Examination of the pressure history records indicate that operationally all Big Hill SPR caverns have been treated similarly. Significantly, new three-dimensional (3-D) imaging methods, applied to old (original) and more recent sonar survey data, have provided much more detailed views of cavern walls, roofs, and floors. This has made possible documentation of the presence of localized deviations from ''smooth'' cylindrical cavern walls. These deviations are now recognized as isolated, linear and/or planar features in the original sonar data (circa early 1990s), which persist to the present time. These elements represent either sites of preferential leaching, localized spalling, or a combination of the two. Understanding the precise origin of these phenomena remains a challenge, especially considering, in a historical sense, the domal salt at Big Hill was believed to be well-characterized. However, significant inhomogeneities in the domal salt that may imply abnormalities in leaching were not noted. Indeed, any inhomogeneities were judged inconsequential to the solution-engineering methods at the time, and, by the same token, to the approaches to modeling the rock mass geomechanical response. The rock mass was treated as isotropic and homogeneous, which in retrospect, appears to have been an over simplification. This analysis shows there are possible new opportunities regarding completing an appropriate site characterization for existing operating cavern fields in the SPR, as well as expansion of current sites or development of new sites. Such characterization should first be consistent with needs identified by this report. Secondly, the characterization needs to satisfy the input requirements of the 3-D solutioning calculational methods being developed, together with 3-D geomechanical analyses techniques which address deformation of a salt rock mass that contains inhomogeneities. It seems apparent that focusing on these important areas could preclude occurrence of unexpected events that would adversely impact the operations of SPR.
Positive-pressure driven overflow-prevention valve with compact trigger mechanism (2017)

A new over-flow prevention valve with a trigger mechanism is designed, fabricated and studied experimentally to evaluate its performances. Loading arms are used to transfer combustible fluid such as oil between tankers and tanks. A loading arm is equipped with an over-flow prevention valve for safety. This valve stops the fluid flow when the fluid exceeds a threshold level in a tank. It must be composed of mechanical elements solely because electric components may induce combustion. Therefore, it uses a pneumatic circuit to detect the fluid level and close the valve. The fabricated valve utilizes positive pressure caused by the height difference of fluid level between the tank and the sensor probe instead of negative pressure that was used in a conventional valve. However, the positive pressure is insufficient to close the valve directly. Therefore, a trigger mechanism is introduced between a piston pushed by the positive pressure and a locking mechanism keeping the valve open. This mechanism generates sufficient force to release the lock and close the main valve from the force pushing the piston. The concept, operation principles and the pneumatic circuit design are presented. Experiments simulating actual operation are carried out with the fabricated valve. The sensor probe is inserted into the water with a constant speed by a single-axis robot instead of flowing oil into the tank. The relation between the velocity and the depth when the valve closes are studied experimentally.

We have developed a narrow linewidth (0.3 nm), tunable (1981-2095 nm) Tm fiber-laser for ranging applications with a master oscillator power amplifier with ~100 W configuration. Power scaling to 200 W is underway.
Diet may influence the oral microbiome composition in cats (2016)

While we observed differences in the oral microbiome between cats on the two diets assessed, the relationship between these differences and gingival health was unclear. Our preliminary results indicate that further analysis of the influence of dietary constituents and texture on the feline oral microbiome is required to reveal the relationship between diet, the oral microbiome and gingival health in cats.
A 0.8V 57GHz-to-72GHz differential-input frequency divider with locking range optimization in 0.13 (2010)

A current-bleeding technique is presented to enhance and maximize the locking range of a differential-input Miller divider (MD) without extra inductor and extra power. The maximum locking range and the associated optimal bleeding current to achieve minimum required output amplitude are derived. Implemented in a 0.13μm CMOS technology and with OdBm input power, the divider prototype measures a locking range of 23.2% from 56.7GHz to 71.6GHz, which is enhanced more than 5 times compared to that of the conventional MD, while consuming the same power of 5mW at 0.8V supply.
Point-of-interests based best path selection using cluster-based routing (2014)

With the rapid introduction of new and innovative applications for handheld and On-board navigation devices and evolution in their hardware capabilities, the need for efficient and convenient resource provision for users arises. We propose user preferred optimal path route selection algorithm incorporating POIs or point of interests (POIs) that the user intends to traverse. Geographic area has been divided into clusters. Different Adjacency Matrices are built for intercluster and the intracluster route to calculate the optimal path using graph theory. In case the desired POIs are not present in the initial calculated optimal route, a fractional distance criteria is proposed. Driver's comfort level and vehicle's fuel consumption are considered while designing the proposed algorithm. Various Google Maps Application Programming Interfaces (APIs) are used to give a host of regional POIs that users can select through mobile and on-board navigation system from a web page. Availability of selected POIs can also be displayed to the user by means of data loggers. The developed software is shown to be more intuitive than the present destination finding softwares.
Differential Phospholipid Binding of α-Synuclein Variants Implicated in Parkinson’s Disease Revealed by Solution NMR Spectroscopy (2009)

Three familial variants of the presynaptic protein alpha-synuclein (alphaS), A30P, E46K, and A53T, correlate with rare inherited Parkinson's disease (PD), while wild-type alphaS is implicated in sporadic PD. The classic manifestation of both familiar and sporadic PD is the formation of fibrillar structures of alphaS which accumulate as the main component in intraneuronal Lewy bodies. At presynaptic termini, the partitioning of alphaS between disordered cytosolic and membrane-bound states likely mediates its proposed role in regulation of reserve pools of synaptic vesicles. Previously, we reported on multiple distinct phospholipid binding modes of alphaS with slow binding kinetics. Here, we report the phospholipid binding properties of the disease variants, viewed by solution NMR in a residue-specific manner. Our results agree qualitatively with previous biophysical studies citing overall decreased lipid affinity for the A30P mutation, comparable affinity for A53T, and an increased level of binding of E46K, relative to wild-type alphaS. Additionally, our NMR results describe the distribution of lipid-bound states for alphaS: the population of the SL1 binding mode (residues 3-25 bound as a helix) is augmented by each of the disease variants, relative to wild-type alphaS. We propose that the SL1 binding mode, which anchors the N-terminus of alphaS in the lipoprotein complex while the hydrophobic NAC region remains dynamically disordered, is prone to intermolecular interactions which progress toward disease-associated oligomers and fibrils. The elevation of the SL1 binding mode, unchecked by a proportionate population of binding modes incorporating the full N-terminal domain, may well account for the increased toxicity of the A30P, E46K, and A53T disease variants of alphaS.
Excitation-emission fluorimeter based on linear interference filters (2004)

We describe the design, properties, and performance of an excitation-emission (EE) fluorimeter that enables spectral characterization of an object simultaneously with respect to both its excitation and its emission properties. Such devices require two wavelength-selecting elements, one in the optical path of the excitation broadband light to obtain tunable excitation and the other to analyze the resulting fluorescence. Existing EE instruments are usually implemented with two monochromators. The key feature of our EE fluorimeter is that it employs lightweight and compact linear interference filters (LIFs) as the wavelength-selection elements. The spectral tuning of both the excitation and the detection LIFs is achieved by their mechanical shift relative to each other by use of two computer-controlled linear step motors. The performance of the LIF-based EE fluorimeter is demonstrated with the fluorescent spectra of various dyes and their mixtures.

Energy Saving MAC for MIMO Systems (2009)

Over the last decade multiple-input and multiple-output (MIMO) systems have been actively researched and started to be deployed in wireless communications owing to the significant increase in channel capacity. In this paper, we propose an energy saving MAC protocol in MIMO (ESMACM) systems by focusing on energy efficiency instead of capacity maximization. ESMACM considers the energy consumption together with the tradeoff between reliability (i.e., diversity) and throughput (i.e., multiplexing gain), and dynamically chooses an appropriate number of antennas for transmission. In computing the total energy consumption, ESMACM counts circuit energy as well as transmission energy. Naturally the circuit energy consumption is directly proportional to the number of active antennas. Through numerical analysis, we confirm that our ESMACM considerably saves energy consumption compared to conventional capacity maximization schemes that use a fixed number of MIMO channels, for a given outage constraint. Our finding is that the capacity maximizing communication which possibly can be regarded best in terms of energy efficiency gives a different solution from the energy minimizing communication.
Feeding Behavior, Development, and Damage by Biotypes B, C, and E of Schizaphis graminum Homoptera: Aphididae) on ‘Wintermalt’, and ‘Post’ Barley (1988)

Greenbug, Schizaphis graminum (Rondani), biotypes B, C, and E, were monitored on susceptible ‘Wintermalt’ and resistant ‘Post’ barley to determine if there were behavioral differences among the biotypes when they fed on resistant and susceptible barley. All biotype-cultivar combinations were tested by observing feeding behavior, fecundity, and damage. Greenbug biotype B had shorter nonfeeding times on the host plant before probing than did biotypes C and E. Biotype B appeared to be less successful in feeding from the phloem of susceptible ‘Wintermalt’ but was relatively more successful than biotypes C and E on the resistant ‘Post.’ Development, reproduction, and particularly dry weight of biotype B were inferior to biotypes C and E on both resistant and susceptible plants. However, biotype B caused the greatest overall reduction in chlorophyll content of infested leaves and should be considered the most virulent but least biologically fit of the three biotypes in these comparisons.
Recommended practices for measuring and reporting outgassing data (2002)

This document recommends a set of uniform procedures for the reporting of outgassing data. Its intention is to establish a consistent set of units, nomenclature, methods of data presentation, and certain experimental parameters in order that outgassing data from different sources is consistently reported so as to be useful to all. This document was prepared by a subcommittee of the Recommend Practices Committee of the American Vacuum Society and is an updating of a previous Recommended Practice published in 1965.
Relationship between the Velocity of Polymerization and Adaptation to Dentin Cavity Wall of Light-cured Composite (1987)

The relationship between the velocity of polymerization of light-cured resins and the wal1-to-wall contraction in a dentine cavity was studied. The final degree and the velocity of polymerization were determined by measuring the quantity of remaining carbon double bonds by infrared spectroscopy with respect to time. Diallylsulfonamide (DASA) as reducing agent in the experimental monomers increased both the velocity and the final degree of polymerization. Hydroquinone-monomethyl ether (MHQ) as inhibitor in the monomers decreased the velocity although its concentration did not affect the final degree. On the other hand, the wall-to-wall contraction increased with increasing content of DASA and with decreasing content of MHQ. From statistical analysis, it was found that the wa11-to-wall contraction was affected by the velocity of polymerization of composite resins, but was not affected by the final degree.
Positioning and Control of an Unmanned Aerial Vehicle (2006)

In the CDIO-project course in Automatic Control, an Autonomous Unmanned Aerial vehicle (UAV) is constructed, utilizing an existing radio controlled model aircraft. By adding an inertial sensor measuring acceleration and rotation, together with a Global Positioning System (GPS) sensor, the aim is to construct an accurate positioning system. This is used by an on board computer to calculate rudder control signals to a set of DC-servos in order to follow a predefined way-point trajectory. The project involves 17 students, which is roughly three times as big as previous projects, and it comprises both positioning, control, and hardware design. Since the project is still ongoing some preliminary results and conclusions are presented.
SGD Implicitly Regularizes Generalization Error (2021)

We derive a simple and model-independent formula for the change in the generalization gap due to a gradient descent update. We then compare the change in the test error for stochastic gradient descent to the change in test error from an equivalent number of gradient descent updates and show explicitly that stochastic gradient descent acts to regularize generalization error by decorrelating nearby updates. These calculations depends on the details of the model only through the mean and covariance of the gradient distribution, which may be readily measured for particular models of interest. We discuss further improvements to these calculations and comment on possible implications for stochastic optimization.
Palladium-Catalyzed Synthesis of Pure, Regiodefined Polymeric Triarylamines (1999)

Triarylamine polymers were prepared by palladium-catalyzed amination of aryl halides, and the electrochemical and magnetic properties of these materials were studied. Through a careful evaluation of the catalytic and polymer chemistry involved in this process, triarylamine polymers that are exclusively linear and free of phosphorus impurity in the polymer chain have been prepared. To suppress molecular weight-limiting side reactions from palladium-catalyzed poly(N-arylaniline) polymerizations, a number of phosphines were screened in reactions of small molecules to form triarylamines. Of these phosphines, tris(o-methoxymethylphenyl)phosphine (7) and tri(tert-butyl)phosphine (8) led to quantitative amination without ligand arylation, aryl bromide hydrodehalogenation, or exchange of phosphine aryl groups with the aryl bromide. When these phosphines were used in polymerizations, significant improvements in molecular weights were observed, but an additional molecular weight limiting side reaction, the formation of cyclic oligomers, was not affected. Strategies to minimize cyclizations that compete with chain growth were explored, including the use of oligomeric monomers that greatly reduced the formation of cyclic oligomers. A chromatographic method completely removed low molecular weight cyclic oligomers. A number of poly(N-arylaniline) derivatives with Mw values as high as 105 g/mol were synthesized by using the optimized palladium-catalyzed method, and the electronic and magnetic properties of these materials were investigated by cyclic voltammetry, magnetic susceptibility, and EPR spectroscopy.
Conditioned media of Kupffer and endothelial liver cells influence protein phosphorylation in parenchymal liver cells. Involvement of prostaglandins (1988)

The possible role of Kupffer and endothelial liver cells in the regulation of parenchymal-liver-cell function was assessed by studying the influence of conditioned media of isolated Kupffer and endothelial cells on protein phosphorylation in isolated parenchymal cells. The phosphorylation state of three proteins was selectively influenced by the conditioned media. The phosphorylation state of an Mr-63,000 protein was decreased and the phosphorylation state of an Mr-47,000 and an Mr-97,000 protein was enhanced by these media. These effects could be mimicked by adding either prostaglandin E1, E2 or D2. Both conditioned media and prostaglandins stimulated the phosphorylase activity in parenchymal liver cells, suggesting that the Mr-97,000 phosphoprotein might be phosphorylase. Parenchymal liver cells secrete a phosphoprotein of Mr-63,000 and pI 5.0-5.5. The phosphorylation of this protein is inhibited by Kupffer- and endothelial-liver-cell media, and prostaglandins E1, E2 and D2 had a similar effect. The data indicate that Kupffer and endothelial liver cells secrete factors which influence the protein phosphorylation in parenchymal liver cells. This forms further evidence that products from non-parenchymal liver cells, in particular prostaglandin D2, might regulate glucose homoeostasis and/or other specific metabolic processes inside parenchymal cells. This stresses the concept of cellular communication inside the liver as a way by which the liver can rapidly respond to extrahepatic signals.
Immunologic response and resistance to experimentally induced pneumonic pasteurellosis in cattle vaccinated with various dosages of lyophilized Pasteurella haemolytica (1986)

SUMMARY Pasteurella haemolytica was lyophilized in an enriched soybean polypeptone broth. Lyophilization in this medium resulted in a mean 10-fold loss in P haemolytica viability, as opposed to up to a 10-fold loss in viability when other media were used. Lyophilized P haemolytica was reconstituted and used as a live vaccine in 3 experiments. Calves were challenge exposed by transthoracic injection with virulent P haemolytica . In experiment 1, 2 subcutaneous injections (7-day interval between injections) with 5 ml of recently harvested (1 × 10 9 colonyforming units [ cfu ]/ml) or lyophilized (1 × 10 8 cfu /ml) P haemolytica significantly ( P &lt; 0.001) enhanced resistance against challenge exposure, compared with resistance in calves given saline solution or sterile medium (control calves) or calves vaccinated with lyophilized organisms at a concentration of 1 × 10 8 cfu /ml. In experiment two, 1, 2, or 5 ml of lyophilized P haemolytica (1 × 10 8 cfu /ml) significantly ( P &lt; 0.05) enhanced resistance, compared with resistance in calves given saline solution (control calves). In experiment three, 1 or 2 injections of lyophilized P haemolytica significantly ( P &lt; 0.01) enhanced resistance against challenge exposure, compared with that of calves given saline solution. The mean lesion score for calves given 1 injection was not significantly higher than the mean lesion score for the group given 2 injections. Vaccination with lyophilized P haemolytica vaccine caused significant ( P &lt; 0.05) increases in serum antibody to P haemolytica somatic antigens, to a carbohydrate-protein subunit of the organism, and to leukotoxin.

Order in two-dimensional binary random arrays (1982)

Abstract Translational and orientational order in randomly packed planar arrays of hard spheres of two different sizes is investigated. For an appropriate size ratio, we find a dilute phase without translational order, but with very-long-range correlations in the orientations of local hexagonal axes. The phase appears to be a quenched analogue of the equilibrium hexatic phase, which appears in two-dimensional melting theories. The peculiar properties of this hexatic glass are attributed to the tendency of a dilute array of large spheres imbedded in a medium of smaller spheres to trap dislocations. Significant orientational correlations also appear in more concentrated mixtures, giving rise to a six-fold modulation of the structure function in large, but finite, samples.
