Demand Response in Smart Distribution System With Multiple Microgrids (2012)

In this paper, an agent based intelligent energy management system is proposed to facilitate power trading among microgrids and allow customers to participate in demand response. The proposed intelligence uses demand response, and diversity in electricity consumption patterns of the customers and availability of power from distributed generators as the vital means in managing power in the system. A new priority index is proposed for customers participating in the market based on frequency and size of load participating in demand response. In order to validate the proposed method, a case study with two interconnected microgrids is simulated. Based on extensive simulation results of the system developed using Java Agent DEvelopment framework (JADE), it has been found that multi-agent based demand response is successful in reducing the system peak in addition to cost benefit for the customers with high priority index.
Optical, thermo-optic, electro-optic, and photoelastic properties of bismuth germanate (Bi_4Ge_3O_12) (1996)

To assess the suitability of bismuth germanate as an electro-optic material for high precision applications, we have confirmed and extended previous data on its refractive index, electro-optic tensor element r(41), and thermal expansion coefficient. In addition, we have measured the thermo-optic coefficient dn/dT, the temperature dependence of the electro-optic coefficient, and the stress-optic tensor elements. From the stress-optic tensor elements and previously published data, we have computed the strain-optic tensor elements. The index of refraction is given, to a good approximation, by the single-term Sellmeier equation, n(2) - 1 = S(0)λ(0)(2)/[1 - (λ(0)/λ)(2)], with S(0) = 95.608 µm(-2) and λ(0) = 0.1807 µm. The thermo-optic coefficient is 3.9 × 10(-5)/°C at 632.8 nm and 3.5 × 10(-5)/°C at 1152.3 nm. The electro-optic tensor element varies between approximately 1.05 and 1.11 pm/V over the spectral range of 550-1000 nm; its normalized effective change with temperature is approximately 1.54 × 10(-4)/°C. The thermal expansion coefficient is 6.3 × 10(-6)/°C over the range 15-125 °C. Values of the stress-optic tensor elements are q(11) - q(12) = -2.995 × 10(-13) m(2)/N and q(44) = -0.1365 × 10(-12) m(2)/N. The strain-optic tensor elements are p(11) - p(12) = -0.0266 and p(44) = -0.0595.
Model-Based Machining Force Control (1999)

Regulating machining forces provides significant economic benefits by increasing operation productivity and improving part quality. Machining force regulation is a challenging problem since the force process varies significantly under normal operating conditions. Since fixed-gain controllers cannot guarantee system performance and stability as the force process varies, a substantial research effort has been invested in the development of adaptive force controllers. However, adaptive controllers can be difficult to develop, analyze, implement, and maintain due to their inherent complexity. Consequently, adaptive machining force controllers have found little application in industry. In this paper, a model-based machining force control approach, which incorporates detailed force process models, is introduced. The proposed design has a simple structure and explicitly accounts for the changes in the force process to maintain system performance and stability. Two model-based machining force controllers are implemented in face milling operations. The stability robustness of the closed-loop system with respect to model parameter uncertainties is analyzed, and the analysis is verified via simulation and experimental studies.

Multi-symbol detection of M-DPSK (2003)

The authors discuss optimal and suboptimal detection methods for improving the error performance when M-ary DPSK (differential phase shift keying) modulation is employed. All procedures use a block of N+1 measurements to produce N data decisions. The motivation is to lessen the energy penalty associated with classical DPSK detection and to approach the performance of fully-coherent detection, but without complicated feedback phase-tracking circuitry and the associated phase-acquisition time. The authors formulate optimal (block) detection under the assumption of unknown carrier phase. Performance analysis and simulation show significant improvement with increasing blocklength, but complexity increases exponentially in blocklength. Suboptimal methods are then proposed which have far less complexity, but retain the improvement over standard DPSK. The primary applications of the present work are in fast-acquisition TDMA (time-division multiple-access) systems with PSK modulation and in frequency-hopping systems using DPSK.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Concise Review: Culture Mediated Changes in Fate and/or Potency of Stem Cells (2011)

Although Gurdon demonstrated already in 1958 that the nucleus of intestinal epithelial cells could be reprogrammed to give rise to adult frogs, the field of cellular reprogramming has only recently come of age with the description by Takahashi and Yamanaka in 2006, which defined transcription factors can reprogram fibroblasts to an embryonic stem cell-like fate. With the mounting interest in the use of human pluripotent stem cells and culture-expanded somatic stem/progenitor cells, such as mesenchymal stem cells, increasing attention has been given to the effect of changes in the in vitro microenvironment on the fate of stem cells. These studies have demonstrated that changes in culture conditions may change the potency of pluripotent stem cells or reprogram adult stem/progenitor cells to endow them with a broader differentiation potential. The mechanisms underlying these fate and potency changes by ex vivo culture should be further investigated and considered when designing clinical therapies with stem/progenitor cells.
Determination of three-dimensional velocity anomalies under a seismic array using first P arrival times from local earthquakes: 1. A homogeneous initial model (1976)

Geiger's method of locating local earthquakes has been extended to include the effect of P velocity variation along the ray paths in three dimensions. The crustal structure was modeled by rectangular blocks, and a parameter was assigned to each block describing the perturbation of P wave slowness in the block. On the basis of an initial model, a set of linear equations for the observed first P arrival times was formulated in terms of the source and medium parameters. The source parameters for all the earthquakes in the data set and medium parameters for all the blocks penetrated by the seismic rays were then determined simultaneously by the damped least squares method. A computer program has been written for the case of a homogeneous initial medium model with constant P velocity. It has been tested with artificial data and applied to a set of local earthquakes recorded by a dense seismic array in Bear Valley, California. The resultant velocity distribution in the top 5 km shows a narrow low-velocity zone of about 5 km/s in the San Andreas fault zone sandwiched between high-velocity regions of about 6 km/s.
Painterly rendering using image salience (2003)

The contribution of this paper is a novel non-photorealistic rendering (NPR) technique, capable of producing an artificial 'hand-painted' effect on 2D images, such as photographs. Our method requires no user interaction, and makes use of image salience and gradient information to determine the implicit ordering and attributes of individual brush strokes. The benefits of our technique are complete automation, and mitigation against the loss of image detail during painting. Strokes from lower salience regions of the image do not encroach upon higher salience regions; this can occur with some existing painting methods. We describe our algorithm in detail, and illustrate its application with a gallery of images.
Aspiration Cytology in Acute Otitis Media (1984)

One hundred and ninety-three middle ear effusion samples from patients with acute otitis media were studied for cellular content and bacteria. Findings were compared with clinical and radiological data. In samples positive for pathogenic bacteria (Haemophilus, pneumococci) neutrophils predominated, whereas monocytes or phagocytes were more numerous in samples with nonpathogens. Inflammatory cells were more frequent in large than in small mastoid air cell systems. Destruction of cell walls was associated with increase of neutrophils and sclerosis with preponderance of lymphocytes, monocytes and phagocytes.
Blogging, communication, and privacy management: Development of the Blogging Privacy Management Measure (2009)

Abstract This study applied Communication Privacy Management (CPM) theory to the context of blogging and developed a validated, theory‐based measure of blogging privacy management. Across three studies, 823 college student bloggers completed an online survey. In study one ( n = 176), exploratory and confirmatory factor analysis techniques tested four potential models. Study two ( n = 291) cross‐validated the final factor structure obtained in the fourth model with a separate sample. Study three ( n = 356) tested the discriminant and predictive validity of the measure by comparing it to the self‐consciousness scale. The Blogging Privacy Management Measure (BPMM) is a multidimensional, valid, and reliable construct. Future research could explore the influence of family values about privacy on blogging privacy rule management.
Machine learning of real-time power systems reliability management response (2017)

In this paper we study how supervised machine learning could be applied to build simplified models of realtime (RT) reliability management response to the realization of uncertainties. The final objective is to import these models into look-ahead operation planning under uncertainties. Our response models predict in particular the real-time reliability management costs and the resulting reliability level of the system. We tested our methodology on the IEEE-RTS96 benchmark. Among the supervised learning algorithms tested, extremely randomized trees, kernel ridge regression and neural networks appear to be the best methods for this application. Furthermore, by using feature “importances” computed by tree-based ensemble methods, we were able to extract the most relevant variables to predict the response of real-time reliability management, and thus obtain a better understanding of the system properties.
Trajectory Generation using Spatial Pythagorean Hodograph Bezier Curves (2015)

This paper presents a cooperative trajectory-generation framework that efficiently computes a set of spatial trajectories for a team of cooperating vehicles, and in particular for unmanned aerial vehicles. The desired and feasible trajectories are generated using Pythagorean Hodograph Bezier curves and satisfy stringent spatial and temporal constraints, do not violate the dynamic constraints of the vehicles, and guarantee spatial separation between the paths for safe operation. A simulation scenario is presented to show the efficacy of the proposed cooperative trajectory-generation framework.

Time-Dependent Conformational Changes in Fibrinogen Measured by Atomic Force Microscopy (2004)

Tapping-mode atomic force microscopy was used to study the time-dependent changes in the structure of fibrinogen under aqueous conditions following adsorption on two model surfaces: hydrophobic graphite and hydrophilic mica. Fibrinogen was observed in the characteristic trinodular form, and the dimensions of the adsorbed molecules were consistent with previously reported values for these surfaces. On the basis of the differences in the relative heights of the D and the E domains, four orientation states were observed for fibrinogen adsorbed on both the surfaces. On graphite, the initial asymmetric orientation states disappeared with spreading over time. Some small lateral movements of the adsorbed proteins were observed on mica during repeated scanning, whereas no such movement was observed on graphite, indicating strong adhesion of fibrinogen to a hydrophobic surface. Spreading kinetics of fibrinogen on the two surfaces was determined by measuring the heights of the D and E domains over a time period of approximately 2 h. On graphite, the heights of both the D and E domains decreased with time to a lower plateau value of 1.0 nm. On mica, the heights of both the D and E domains showed an increase, rising to an upper plateau value of approximately 2.1 nm. The spreading of the D and E domains on graphite was analyzed using an 'exponential-decay-of-height' model. A spreading rate constant of approximately 4.7 x 10(-4) s(-1) was observed for the whole fibrinogen molecule adsorbed on graphite, corresponding to a free energy of unfolding of approximately 37 kT. Extrapolation of the exponential curve in the model to t = 0 yielded values of 2.3 and 2.2 nm for the heights of the D and the E domains at the time of contact with the hydrophobic graphite substrate, significantly less than their free solution diameters. A two-step spreading model is proposed to explain this observation.
How lac repressor recognizes lac operator. (1978)

Nucleotide analogs were substituted for unmodified nucleotides at specific sites in the lac operator sequence by a combination of chemical and enzymatic procedures. The nitrocellulose filter assay was used to study the interactions of these modified operators with wild-type (SQ) and tight-binding (QX86) lac repressors. These studies implicate directly the 5 methyl of thymine and the 2 amino of guanine as important operator-repressor contact sites. Furthermore, when these findings are combined with published results from other laboratories, a model for the lac operator-lac repressor interaction can be derived. Two important postulates follow from this model. (i) The repressor interacts at specific and defined sites with the N7 of guanine, the 5 methyl of thymine, the 2 amino of guanine, and the central major groove of the operator. (ii) The repressor binds to one side of the operator.
Misunderstandings about object-oriented design (2008)

In this paper we present our experience using code reviews in a CS2 course. In particular, we highlight a series of misunderstandings of object-oriented (OO) concepts we observed as a by-product of the code review exercise. In our activity, we asked students to review code, rate it using a rubric, and to justify their explanation. The students were asked to review two solutions to a project from a previous year. Through examples of their explanations, we found that students had a number of basic misunderstandings of object-oriented principles. In this paper, we present our observations of the misunderstandings, and present some general observations of how code reviews can be used as an assessment tool in CS2.

Robust Physical-World Attacks on Deep Learning Models (2017)

Recent studies show that the state-of-the-art deep neural networks (DNNs) are vulnerable to adversarial examples, resulting from small-magnitude perturbations added to the input. Given that that emerging physical systems are using DNNs in safety-critical situations, adversarial examples could mislead these systems and cause dangerous situations.Therefore, understanding adversarial examples in the physical world is an important step towards developing resilient learning algorithms. We propose a general attack algorithm,Robust Physical Perturbations (RP2), to generate robust visual adversarial perturbations under different physical conditions. Using the real-world case of road sign classification, we show that adversarial examples generated using RP2 achieve high targeted misclassification rates against standard-architecture road sign classifiers in the physical world under various environmental conditions, including viewpoints. Due to the current lack of a standardized testing method, we propose a two-stage evaluation methodology for robust physical adversarial examples consisting of lab and field tests. Using this methodology, we evaluate the efficacy of physical adversarial manipulations on real objects. Witha perturbation in the form of only black and white stickers,we attack a real stop sign, causing targeted misclassification in 100% of the images obtained in lab settings, and in 84.8%of the captured video frames obtained on a moving vehicle(field test) for the target classifier.
Analysis of mixed-signal manufacturability with statistical TCAD (2002)

We have developed a method which combines TCAD simulation with statistical analysis of empirical data. As a result, we can determine worst case models before a significant sample size of fabricated devices can be characterized. As measured data is collected we use models built from simulated data to analyze measured in-line and e-test data. We determine what is the minimum set of e-test or in-line measurements to control the SPICE model parameters. As a result we can provide predictive worst case models, update them based on fabrication data as development proceeds, and finally use them to control the manufacturing line.
Protein Kinase Cα Phosphorylates the TRPC1 Channel and Regulates Store-operated Ca2+ Entry in Endothelial Cells (2004)

The TRPC1 (transient receptor potential canonical-1) channel is a constituent of the nonselective cation channel that mediates Ca2+ entry through store-operated channels (SOCs) in human endothelial cells. We investigated the role of protein kinase Calpha (PKCalpha) phosphorylation of TRPC1 in regulating the opening of SOCs. Thrombin or thapsigargin added to the external medium activated Ca2+ entry after Ca2+ store depletion, which we monitored by changes in cellular Fura 2 fluorescence. Internal application of the metabolism-resistant analog of inositol 1,4,5-trisphosphate (IP3) activated an inward cationic current within 1 min, which we recorded using the whole cell patch clamp technique. La3+ or Gd3+ abolished the current, consistent with the known properties of SOCs. Pharmacological (Gö6976) or genetic (kinase-defective mutant) inhibition of PKCalpha markedly inhibited IP3-induced activation of the current. Thrombin or thapsigargin also activated La3+-sensitive Ca2+ entry in a PKCalpha-dependent manner. We determined the effects of a specific antibody directed against an extracellular epitope of TRPC1 to address the functional importance of TRPC1. External application of the antibody blocked thrombin- or IP3-induced Ca2+ entry. In addition, we showed that addithrombin or thapsigargin induced phosphorylation of TRPC1 within 1 min. Thrombin failed to induce TRPC1 phosphorylation in the absence of PKCalpha activation. Phosphorylation of TRPC1 and the resulting Ca2+ entry were essential for the increase in permeability induced by thrombin in confluent endothelial monolayers. These results demonstrate that PKCalpha phosphorylation of TRPC1 is an important determinant of Ca2+ entry in human endothelial cells.
Gaussian Basis Set for Molecular Wavefunctions Containing Third-Row Atoms (1970)

Renal vascular Doppler imaging: clinical benefits of power mode. (1998)

Power Doppler ultrasound (US) is a new technology that is superior to conventional color Doppler imaging in the detection of blood flow. Because of its greater sensitivity to flow and reduced angle dependence, power Doppler US demonstrates optimal color filling of renal pedicular vessels and allows improved evaluation of the renal parenchymal microvasculature. Power Doppler US was used as an adjunct to conventional color Doppler imaging in technically challenging cases and to improve evaluation of renal vascular disorders in a series of 916 patients. The primary clinical advantages of using power Doppler US compared with conventional color Doppler imaging include better morphologic appreciation of atherosclerotic changes in the renal artery wall, allowing improved diagnostic performance especially in hemodynamically nonsignificant plaques; ability to differentiate between subocclusive renal artery stenosis and occlusion; increased confidence in the diagnosis of renal vein thrombosis and in the assessment of caval tumor thrombus; and better appreciation of renal cortical perfusion defects. In addition, because of its greater sensitivity to perivascular artifact, power Doppler US has the potential to increase the detection rate for intrarenal arteriovenous fistulas.
Determinants of pancreatic β‐cell regeneration (2008)

Recent studies have revealed a surprising plasticity of pancreatic beta-cell mass. beta-cell mass is now recognized to increase and decrease in response to physiological demand, for example during pregnancy and in insulin-resistant states. Moreover, we and others have shown that mice recover spontaneously from diabetes induced by killing of 70-80% of beta-cells, by beta-cell regeneration. The major cellular source for new beta-cells following specific ablation, as well as during normal homeostatic maintenance of adult beta-cells, is proliferation of differentiated beta-cells. More recently, it was shown that one form of severe pancreatic injury, ligation of the main pancreatic duct, activates a population of embryonic-type endocrine progenitor cells, which can differentiate into new beta-cells. The molecular triggers for enhanced beta-cell proliferation during recovery from diabetes and for activation of embryonic-type endocrine progenitors remain unknown and represent key challenges for future research. Taken together, recent data suggest that regenerative therapy for diabetes may be a realistic goal.

The Intelligent Classroom: Beyond Four Walls (2011)

It has become standard practice to use the traditional information technologies such as web and email in education. But as the University campus becomes increasingly deployed with interconnected computing technology, we begin to ask how the resulting &ldquo;iCampus&rdquo; resource can be used in new and novel ways. This paper builds upon our previous work in the area of intelligent environments and goes beyond the typical use of computing technology within education. We report on our current research that aims to apply mixed reality and ubiquitous computing paradigms to enrich the teaching and learning experience and describe our deployments and innovations across the University of Essex campus.
