Two Is Not Enough: Privacy Assessment of Aggregation Schemes in Smart Metering (2017)

Abstract The widespread deployment of smart meters that frequently report energy consumption information, is a known threat to consumers’ privacy. Many promising privacy protection mechanisms based on secure aggregation schemes have been proposed. Even though these schemes are cryptographically secure, the energy provider has access to the plaintext aggregated power consumption. A privacy trade-off exists between the size of the aggregation scheme and the personal data that might be leaked, where smaller aggregation sizes leak more personal data. Recently, a UK industrial body has studied this privacy trade-off and identified that two smart meters forming an aggregate, are sufficient to achieve privacy. In this work, we challenge this study and investigate which aggregation sizes are sufficient to achieve privacy in the smart grid. Therefore, we propose a flexible, yet formal privacy metric using a cryptographic game based definition. Studying publicly-available, real world energy consumption datasets with various temporal resolutions, ranging from minutes to hourly intervals, we show that a typical household can be identified with very high probability. For example, we observe a 50% advantage over random guessing in identifying households for an aggregation size of 20 households with a 15-minutes reporting interval. Furthermore, our results indicate that single appliances can be identified with significant probability in aggregation sizes up to 10 households.
Infrared photometry of giants in the globular cluster NGC 4833 (1986)

Infrared broad band JHK photometry is presented for 21 red giants in the metal-poor globular cluster NGC 4833. The color magnitude and color-color correlations are discussed. Bolometric luminosities are calculated from apparent K magnitudes by using bolometric corrections for giants. A comparison with Yale isochrones gives the most likely age of this cluster to be about 12 x 10 to the 9th yr
Optimizing the configuration of a superconducting photonic band gap accelerator cavity to increase the maximum achievable gradients (2014)

We present a design of a superconducting rf photonic band gap (SRF PBG) accelerator cell with specially shaped rods in order to reduce peak surface magnetic fields and improve the effectiveness of the PBG structure for suppression of higher order modes (HOMs). The ability of PBG structures to suppress long-range wakefields is especially beneficial for superconducting electron accelerators for high power free-electron lasers (FELs), which are designed to provide high current continuous duty electron beams. Using PBG structures to reduce the prominent beam-breakup phenomena due to HOMs will allow significantly increased beam-breakup thresholds. As a result, there will be possibilities for increasing the operation frequency of SRF accelerators and for the development of novel compact high-current accelerator modules for the FELs.
Cyclization of the Monoterpene Citronellal to Isopulegol: A Biomimetic Natural Product Synthesis (2000)

Cyclization of the monoterpene (S)-(--)-citronellal takes place rapidly in the presence of tin(IV) chloride in methylene chloride at 0 °C, affording the cyclic monoterpene isopulegol in a yield of 85%. The experiment reported here mimics the reaction found in the biosynthetic pathway leading to another well-known natural product, menthol. The starting material and final product display easily interpreted infrared and proton-NMR spectra. Coupling patterns and constants produced by the C-3 methine proton establish the all-equatorial substitution pattern of the cyclohexane ring system found in the product. Either a carbocation process or an ene reaction can be used to describe the mechanistic details of this reaction.
Mapping the T cell epitopes of the <i>Babesia bovis</i> antigen 12D3: implications for vaccine design (1998)

The Babesia bovis antigen 12D3 was analysed to identify potential T-cell epitopes. Two predictive algorithms identified 13 possible sites but there was minimal agreement between the different predictive methods. Experimental determination of the T-cell epitopes recognized by nine cattle was achieved using a panel of overlapping peptides which identified seven different epitopes, five of which were clustered together around residues 210-320 of the molecule. No T cell epitopes were located within the tightly disulphide bonded core of 12D3. Using a series of truncated peptides, the location of two of the epitopes was mapped to residues 35-43 and 266-275. The sequences of these two epitopes was compared with a database of previously described binding motifs for MHC II alleles and each epitope was found to contain three sequence motifs recognized by HLA-DR alleles. The BoLA-DRB3 alleles occurring in these cattle were determined by a sequence specific oligonucleotide hybridization assay. Within those cattle whose T cells proliferated in response to 12D3, there was a consistent pattern of epitope recognition and presence of particular DRB3 alleles. The implications for effective vaccine design are discussed.
Electroactive 3D Scaffolds Based on Silk Fibroin and Water‐Borne Polyaniline for Skeletal Muscle Tissue Engineering (2017)

Silk fibroin (SF) with good biocompatibility and degradability has great potential for tissue engineering. However, the SF based scaffolds lack the electroactivity to regulate the myogenic differentiation for the regeneration of muscle tissue, which is sensitive to electrical signal. Herein, a series of electroactive biodegradable scaffolds based on SF and water-soluble conductive poly(aniline-co-N-(4-sulfophenyl) aniline) (PASA) via a green method for skeletal muscle tissue engineering are designed. SF/PASA scaffolds are prepared by vortex of aqueous solution of SF and PASA under physiological condition. Murine-derived L929 fibroblast and C2C12 myoblast cells are used to evaluate cytotoxicity of SF/PASA scaffolds. Moreover, myogenic differentiation of C2C12 cells is investigated by analyzing the morphology of myotubes and related gene expression. These results suggest that electroactive SF/PASA scaffolds with a suitable microenvironment, which can enhance the myogenic differentiation of C2C12 cells, have a great potential for skeletal muscle regeneration.
DCWPL: a coordination language for the development of collaborative applications (1997)

A collaborative application must support the interaction of a group of users that share some information and have common or complementary goals. Many conflicting situations can arise during a computer supported meeting or collaborative session when two or more participants access this shared information. In addition to data consistency issues (data-level conflicts), collaborative applications should address the specification of coordination mechanisms to control the way users can interact with the application (user-level conflicts). These coordination mechanisms can vary from session to session, or even during the same session, as users may need to establish new ways to interact with each other.
A new implementation model is introduced in this thesis to help programmers build new collaborative applications or re-engineer single-user applications. This model decouples coordination from computational issues, separating an application into three different components: visual presentation, underlying data, and coordination. This third component allows programmers to specify the set of data- and user-level coordination mechanisms mentioned above. Moreover, programmers can define multiple coordination components to allow users to select the mechanisms that best suit their needs during a collaborative session.
This thesis describes a programming language that enables developers to specify the coordination component of a collaborative application. A coordination program represents the group interaction rules, such as protocols and policies, that control the way users can interact with one another. Similarly, programmers can also include the appropriate concurrency control mechanisms to address data consistency issues found in these applications.
A coordination program is executed by a language runtime interpreter. This interpreter controls the execution of any user action by following the specifications in the coordination program. Furthermore, new coordination programs can be loaded in the runtime interpreter at any time, allowing end-users to change the coordination mechanisms during an ongoing collaborative session. A description of the runtime interpreter functionality and its implementation is also included in this thesis.
Haptic Data Reduction and Protection in Multimodal Virtual Environments (2010)

The emerging field of haptics, which enables the sensing and manipulation of virtual environments through touch, is recognized as an important element in the area of human computer interaction. Many of its applications, including medical training, rehabilitation, security, entertainment, etc. involve the transmission, storage, protection, and analysis of haptic information. However, the multi-dimensional and time-varying nature of haptic data along with the fact that high sampling frequencies are required when generating haptic signals, motivate the research of haptic data reduction. This thesis discusses two important and related topics: data reduction and protection in multimodal visual-haptic virtual environments. The focus of the first topic is on the design, evaluation, and analysis of haptic data reduction techniques in order to: (1) Improve packet transmission in telehaptic systems, and (2) reduce the dimensionality of the inherently large haptic datasets. In the former case, robust perception-based data reduction methods in 3- and 6-degree-of-freedom telehaptic systems are derived. The proposed techniques are evaluated in different experimental settings, including a haptic-enabled telesurgery simulation, and demonstrate a significant reduction in haptic data traffic while maintaining a high-quality telehaptic experience. In the latter case, data reduction in haptic information analysis problems is investigated. Specifically, data reduction methods are presented within the context of haptic data mining and knowledge discovery to help facilitate the analysis of the inherently high-dimensional haptic datasets. Experiments using datasets of haptic-based handwritten signatures demonstrate the accuracy of the techniques in reducing the high dimensionality of haptic feature spaces. The protection of haptic information through digital watermarking is also investigated in this thesis due to its conceptual similarity to haptic data reduction and compression. A foundational study is conducted to examine the role of multisensory feedback in the perception of a watermark embedded in a haptic-enabled 3D virtual surface. In particular, the analysis aims to answer numerous important questions in this brand-new research area, including: Do watermarks inspected using multimodal feedback (vision + haptic) result in very different detection thresholds from those detected using a single sensory modality; or more importantly, whether multimodal visual-haptic feedback improves the perception of watermarks embedded in 3D meshes.
Control of unstable steady states by time-delayed feedback methods (2005)

We show that time-delayed feedback methods, which have successfully been used to control unstable periodic orbits, provide a tool to stabilize unstable steady states. We present an analytical investigation of the feedback scheme using the Lambert function and discuss effects of both a low-pass filter included in the control loop and nonzero latency times associated with the generation and injection of the feedback signal.

The measurement of HP-IP leakage flow: The largest source of uncertainty in code tests of low pressure turbines (1995)

The flow rate of the internal leakage between the HP and IP turbines must be known when testing LP turbine performance in reheat units. It is shown that the Booth Kautzmann temperature shift test is the only method for measuring this flow that can be used in a significant number of turbines and that has potential for reasonable accuracy. Data is presented that shows that there is still a large level of uncertainty in the flow measured by the temperature shift test. It is shown that this measurement is a greater source of uncertainty in the acceptance testing of LP turbines, than all other measurements combined. The possible causes of errors in the method are discussed, and the specific test procedures that appear to be most susceptible to these errors are identified. A research program, being conducted by the New England Power Co., the Electric Power Research Institute, and Encotech, PC, is described. The goal of this program is to identify the best test procedures for the temperature shift test, and to estimate the uncertainty achievable when these procedures are followed.
Preparation of epitaxial hexagonal YMnO3 thin films and observation of ferroelectric vortex domains (2016)

Abstract Ferroelectric vortex is one of unique domain structures in the hexagonal R MnO 3 ( R =Sc, Y, Ho-Lu) systems. This vortex pattern is quite sensitive to crystal imperfections, such as lattice defects and oxygen vacancies, which has been previously observed and studied in a single-crystal structure. Here we report epitaxial growth of hexagonal YMnO 3 thin films on platinum-coated Al 2 O 3 (0001) substrates. High-quality epitaxial YMnO 3 (0001)/Pt(111)/Al 2 O 3 (0001) heterostructures with sharp interfaces have been achieved and characterised by using X-ray diffractometry and transmission electron microscopy. Reversible ferroelectric domain structures have been achieved and observed with well-established piezoresponse hysteresis. Furthermore, the ferroelectric vortex domain patterns with a typical size of ~20 nm have been observed, representing a significant progress in the fabrication and exploration of topological vortices in hexagonal R MnO 3 thin films.
Stretch-stimulated surfactant synthesis is coordinated by the paracrine actions of PTHrP and leptin (2002)

Intrauterine lung development, culminating in physiological pulmonary surfactant production by epithelial type II (TII) cells, is driven by fluid distension through unknown mechanisms. Differentiation of alveolar epithelial and mesenchymal cells is mediated by soluble factors like parathyroid hormone-related protein (PTHrP), a stretch-sensitive TII cell product. PTHrP stimulates pulmonary surfactant production by a paracrine feedback loop mediated by leptin, a soluble product of the mature lipofibroblast (LF). When LFs and TIIs are stretched in coculture, there is a fivefold increase in surfactant phospholipid synthesis that can be "neutralized" by inhibitors of PTHrP or leptin, implicating a paracrine feedback loop in this mechanism. Stretching LFs stimulates PTHrP binding (2.5-fold) and downstream stimulation of triglyceride uptake quantitatively (15-25%) due to upregulation of adipose differentiation-related protein expression. Stretching TII cells increases leptin stimulation of their surfactant phospholipid synthesis threefold, suggesting that retrograde signaling by leptin to TII cells is also stretch sensitive. We conclude that the effect of stretch on alveolar LF and TII differentiation is coordinated by PTHrP, leptin, and their receptors.
Several key problems in model-based image sequence compression by using interframe AUs correlation (2002)

Model-based image coding has received much attention for it could gain a big compression ratio and well form the basis of very low bit rates visual transmissions. Many authors have contributed a lot to this area. However, some key problems are not well solved in practice. In this paper, the human face model and its invariant representation, textural mapping for natural synthesizing of facial images, the occlusion problem in the case of face rotation, real time automatic extraction of face feature points, and a better performance criteria suitable for facial expression analysis/synthesis are discussed. The results obtained by computer simulation are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

An overview of frame relay technology (2002)

The author provides an overview of frame relay services and technology. Their evolution and standardization are described. Frame relay is a technology for access to wide area networks. The frame relay protocol operates at a sublayer of the data link layer, which provides the minimum functionality needed to take advantage of the statistical properties of the communication. Unlike preexisting protocol suites in use in general topology subnetworks, it also performs relaying, and multiplexing at this sublayer. Other data link layer functions are provided only in systems connected to the edges of the frame relay subnetwork. Protocol architecture, syntax, and procedures are discussed, using a layered approach to describe the interactions of the various protocols. The broad implications of statistical resource sharing in frame relay are considered. Particular attention is given to the advantages of using fast packet technologies (e.g. ATM) in support of frame relay for transmission and switching.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A maximum likelihood N-camera stereo algorithm (1994)

This paper extends results of a maximum likelihood two-frame stereo algorithm to the case of N cameras. The N-camera stereo algorithm determines the "best" set of correspondences between a given pair of cameras, referred to as the principal cameras. Knowledge of the relative positions of the cameras allows the 3D point hypothesized by an assumed correspondence of two features in the principal pair to be projected onto the image plane of the remaining N-2 cameras. These N-2 points are then used to verify proposed matches. Not only does the algorithm explicitly model occlusion between features of the principal pair, but the possibility of occlusions in the N-2 additional views is also modelled. The benefits and importance of this are experimentally verified. Like other multi-frame stereo algorithms, the computational and memory costs of this approach increase linearly with each additional view. Experimental results are shown for two outdoor scenes. It is clearly demonstrated that the number of correspondence errors is significantly reduced as the number of views/cameras is increased.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Preparation and characterization of rilpivirine solid dispersions with the application of enhanced solubility and dissolution rate (2015)

Rilpivirine (RPV) is a pharmaceutical drug used for the treatment of HIV infection. The drug is characterized with poor aqueous solubility and dissolution rate leading to low bioavailability of the drug. Hence, there is a need for the improvement of the solubility and dissolution of such drugs. In this exertion, enhancement of the solubility and dissolution of the practically water insoluble drug rilpivirine was achieved by solid dispersion (SD) preparation using solvent evaporation method which eventually leads to bioavailability enhancement. SD's were formed using Kollidon VA 64 which is a water-soluble copolymer and varying copolymer ratio to Avicel PH-101, Gelucire 50/13 and lecithin soya. Solubility studies were carried out to establish the solubility-enhancing property of the SD's. To support solubility analysis results, powder dissolution studies were carried out. The SD's were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, X-ray powder diffraction studies, scanning electron microscopy. It was found that the SD's formed showed the absence of crystalline nature of the drug and its conversion to amorphous state. The solubility and dissolution of the rilpivirine SD's were enhanced. There is a 14.9 fold increase in solubility for Drug: Kollidan VA 64: Gelucire 50/13 (1:4:1). For Drug: Kollidan VA 64 (1:5), Drug: Kollidan VA 64: Lecithin soya (1:4:1) and Drug: Kollidan VA 64: Avicel PH-101 (1:4:1) it was 5.9, 5.4 and 4.2 respectively. In-vitro drug release kinetics was investigated. This study demonstrates the use of solvent evaporation method for the preparation of SD’S in solubility and dissolution enhancement.
