Multiple power quality event detection and classification using modified S-transform and WOA tuned SVM classifier (2021)

In this paper, a novel method for the classification of power quality events is illustrated. Fifteen types of power quality events consisting of single and multi-stage disturbances are considered for the study. A database of the synthetic PQ events is generated in MATLAB using mathematical models. The generated signals are passed through a novel modified Stockwell transform consisting of a second-order Gaussian window that provides the ST matrix. From the ST matrix, various statistical features such as energy and standard deviation of the magnitude and phase contour are extracted and given as input to support vector machine (SVM). Furthermore, to improve the performance of SVM, a novel meta-heuristic technique called whale optimisation algorithm (WOA) is used to tune the hyperparameters of the SVM classifier. The performance of the proposed method is analysed under noisy and noiseless conditions. It is observed that WOA tuned SVM provides improved classification accuracy than other widely used meta-heuristic optimisation algorithms such as particle swarm optimisation (PSO) tuned SVM and genetic algorithm (GA) tuned SVM. Further, two novel circuits for the generation of sag, swell, and interrupt are developed and the proposed technique is validated on real-time signals obtained from the circuits.

Personalized augmented reality for anatomy education (2015)

Anatomy education is a challenging but vital element in forming future medical professionals. In this work, a personalized and interactive augmented reality system is developed to facilitate education. This system behaves as a "magic mirror" which allows personalized in-situ visualization of anatomy on the user's body. Real-time volume visualization of a CT dataset creates the illusion that the user can look inside their body. The system comprises a RGB-D sensor as a real-time tracking device to detect the user moving in front of a display. In addition, the magic mirror system shows text information, medical images, and 3D models of organs that the user can interact with. Through the participation of 7 clinicians and 72 students, two user studies were designed to respectively assess the precision and acceptability of the magic mirror system for education. The results of the first study demonstrated that the average precision of the augmented reality overlay on the user body was 0.96 cm, while the results of the second study indicate 86.1% approval for the educational value of the magic mirror, and 91.7% approval for the augmented reality capability of displaying organs in three dimensions. The usefulness of this unique type of personalized augmented reality technology has been demonstrated in this paper.

Voronoi Diagram in the Laguerre Geometry and Its Applications (1985)

We extend the concept of Voronoi diagram in the ordinary Euclidean geometry for n points to the one in the Laguerre geometry for n circles in the plane, where the distance between a circle and a point is defined by the length of the tangent line, and show that there is an $O(n\log n)$ algorithm for this extended case. The Voronoi diagram in the Laguerre geometry may be applied to solving effectively a number of geometrical problems such as those of determining whether or not a point belongs to the union of n circles, of finding the connected components of n circles, and of finding the contour of the union of n circles. As in the case with ordinary Voronoi diagrams, the algorithms proposed here for those problems are optimal to within a constant factor. Some extensions of the problem and the algorithm from different viewpoints are also suggested.
Real-time multimedia streams in a differentiated services network (2002)

Multimedia applications are becoming increasingly popular on the Internet. These include semi real-time applications like video playback, but also interactive applications with hard real-time requirements like Internet telephony or videoconferencing. Common to the real-time applications is an inevitable requirement for transmission services with certain guaranteed qualities. The differentiated services architecture aims at providing these services. A prioritized transmission, which is necessary in the case of real-time data, can be achieved by applying the expedited forwarding, defined as a premium service. Nevertheless, especially if current hierarchical video encoding techniques are used, great benefits can be gained by extending the expedited forwarding by different levels of forwarding guarantees. Doing so allows finely tuned reactions to congestion in the network, based on the importance of the individual data packets, which is given by the hierarchy of the video encoding layers. In this paper we present a queue management and scheduling model, which is the basis for a new differentiated services per hop behavior group. The per hop behavior group extends the expedited forwarding by certain forwarding guarantees, as already applied by the assured forwarding per hop behavior group. We show simulation results, which prove the usefulness of this extension, especially for the transmission of hierarchically encoded video streams.
Room Temperature Inorganic “Quasi‐Molten Salts” as Alkali‐Metal Electrolytes (1996)

Room temperature inorganic liquids of high ionic conductivity have been prepared by reacting Lewis acid with sulfonyl chlorides. The mechanism is not clear at this time since a crystal structure study of the 1:1 complex with (Tm = 30°C) is not consistent with a simple chloride transfer to create anions. The liquid is in a state somewhere between "ionic" and "molecular". A new term "quasi‐molten salt" is adopted to describe this state. A comparably conducting liquid can be made using in place of . Unlike their organic counterparts based on ammonium cations (e.g., pyridinium or imidazolium) which reduce in the presence of alkali metals, this inorganic class of cation shows great stability against electrochemical reduction (ca. ‐1.0 V vs. /Li), with the useful consequence that reversible lithium and sodium metal deposition/stripping can be supported. The electrochemical "window" for these quasi‐salts with ranges up to 5.0 V, and their room temperature conductivities exceed 10−4 S/cm. They dissolve lithium and sodium tetrachloroaluminates up to mole fraction ∼0.6 at 100°C and intermediate compositions are permanently stable at ambient. The resultant lithium or sodium salt solutions exhibit electrochemical windows of 4.5 ∼ 5.0 V vs. /Li or /Na and show room temperature conductivities of . In preliminary charge/discharge tests, the cell Li/"quasi‐ionic liquid electrolyte"/ showed a discharge capacity of ca. 110 mAh/(g of cathode) and sustained 80% of the initial capacity after 60 cycles, indicating that these quasi‐molten salt‐based electrolytes are promising candidates for alkali‐metal batteries.
How to win friends and influence people, truthfully (2012)

Throughout the past decade there has been extensive research on algorithmic and data mining techniques for solving the problem of influence maximization in social networks: if one can incentivize a subset of individuals to become early adopters of a new technology, which subset should be selected so that the word-of-mouth effect in the social network is maximized? Despite the progress in modeling and techniques, the incomplete information aspect of the problem has been largely overlooked. While data can often provide the network structure and influence patterns may be observable, the inherent cost individuals have to become early adopters is difficult to extract.
Ricin and Ricin-Containing Immunotoxins: Insights into Intracellular Transport and Mechanism of action in Vitro (2013)

Ricin is a type II ribosome inactivating protein (RIP) isolated from castor beans. Its high toxicity classifies it as a possible biological weapon. On the other hand, ricin linked to specific monoclonal antibodies or used in other conjugates has powerful medical applications. Ricin consists of an A-chain (RTA) that damages ribosomes and inhibits protein synthesis, and a B-chain that plays a role in binding and cellular uptake. A number of recent studies have demonstrated that ricin-induced inhibition of protein synthesis is not the only mechanism responsible for cell death. It turns out that ricin is able to induce apoptosis in different cell lines and multiple organs in animals. However, the molecular link between protein synthesis inhibition and ricin-dependent triggering of apoptotic cell death is unclear. This review describes the intracellular transport of ricin and ricin-based immunotoxins and their mechanism of action in different non-malignant and cancer cell lines. Moreover, various ricin-containing immunotoxins, their composition, medical applications and side-effects will be described and discussed. Understanding the mechanism of action of ricin-based immunotoxins will facilitate construction of effectively acting immunotoxins that can be used in the clinic for cancer treatment.
Cellular Uptake of Cell-Penetrating Peptides (2004)

Cellular machinery is protected from the surrounding by two-layer lipid membrane that is impermeable for most substances unnecessary for cellular metabolism. Unfortunately, from a cellular point of view, most new generation drugs, designed to act on gene regulation and transcription, are also considered to be unnecessary for metabolism and therefore showing poor, if any, intracellular localization. To overcome this obstacle, several chemical and physical methods have been developed, improving the uptake, but, on the other hand, also showing some unwanted side effects or limitations for in vivo applications. This dictates the continuing need for improved drug delivery and one way seems to be the relatively new class of compounds - cell-penetrating peptides (CPPs). Discovered approximately a decade ago, the content of this class is growing rapidly, containing now more than 100 compounds, which shows the intensity of work in this field. CPPs have already been shown to translocate cellular membranes in an unknown, seemingly receptor-independent and non-endocytotic manner. Moreover, they are able to deliver cargoes exceeding their own size up to 100-fold into a cellular milieu both in vitro and in vivo. The variety of different cargoes includes, but is not limited to: DNA, antisense PNA, oligonucleotides and small proteins. Recent data argues though that endocytosis is involved and contributes in some cases to the main part of the translocation. This review summarizes data on mechanisms of cell-penetrating peptides. Keywords: cell-penetrating peptides, translocation, internalization, fixation, endocytosis
In vivo efficacy of XR9051, a potent modulator of P-glycoprotein mediated multidrug resistance (1999)

Overexpression of P-glycoprotein (P-gp) is a potential cause of multidrug resistance (MDR) in tumours. We have previously reported that XR9051 (N-(4-(2-(6,7-dimethoxy-1,2,3,4-tetrahydro-2-isoquinolyl)ethyl)phe nyl)-3-((3Z,6Z)-6-benzylidene-1-methyl-2,5-dioxo-3-pipera zinylidene)methylbenzamide) is a potent and specific inhibitor of P-gp, which reverses drug resistance in several murine and human MDR cell lines. In this study we have evaluated the in vivo efficacy of this novel modulator in a panel of murine and human tumour models and examined its pharmacokinetic profile. Efficacy studies in mice bearing MDR syngeneic tumours (P388/DX Johnson, MC26) or human tumour xenografts (A2780AD, CH1/DOXr, H69/LX) demonstrated that co-administration of XR9051 significantly potentiated the anti-tumour activity of a range of cytotoxic drugs. This modulatory activity was observed following parenteral and oral co-administration of XR9051. In addition, the combination schedules were well-tolerated. Following intravenous administration in mice, XR9051 is rapidly distributed and accumulates in tumours and other tissues. In addition, the compound is well-absorbed after oral administration. These data suggest that XR9051 has the potential for reversing clinical MDR mediated by P-glycoprotien.
A Simple Method for Removal of the <b><i>Chlamydomonas reinhardtii</i></b> Cell Wall Using a Commercially Available Subtilisin (Alcalase) (2018)

The algal cell wall is a potent barrier for delivery of transgenes for genetic engineering. Conventional methods developed for higher plant systems are often unable to penetrate or remove algal cell walls owing to their unique physical and chemical properties. Therefore, we developed a simple transformation method for Chlamydomonas reinhardtii using commercially available enzymes. Out of 7 enzymes screened for cell wall disruption, a commercial form of subtilisin (Alcalase) was the most effective at a low concentration (0.3 Anson units/mL). The efficiency was comparable to that of gamete lytic enzyme, a protease commonly used for the genetic transformation of C. reinhardtii. The transformation efficiency of our noninvasive method was similar to that of previous methods using autolysin as a cell wall-degrading enzyme in conjunction with glass bead transformation. Subtilisin showed approximately 35% sequence identity with sporangin, a hatching enzyme of C. reinhardtii, and shared conserved active domains, which may explain the effective cell wall degradation. Our trans-formation method using commercial subtilisin is more reliable and time saving than the conventional method using autolysin released from gametes for cell wall lysis.

Anatomical aspects of sinus floor elevations (2000)

Inadequate bone height in the lateral part of the maxilla forms a contra-indication for implant surgery. This condition can be treated with an internal augmentation of the maxillary sinus floor. This sinus floor elevation, formerly called sinus lifting, consists of a surgical procedure in which a top hinge door in the lateral maxillary sinus wall is prepared and internally rotated to a horizontal position. The new elevated sinus floor, together with the inner maxillary mucosa, will create a space that can be filled with graft material. Sinus lift procedures depend greatly on fragile structures and anatomical variations. The variety of anatomical modalities in shape of the inner aspect of the maxillary sinus defines the surgical approach. Conditions such as sinus floor convolutions, sinus septum, transient mucosa swelling and narrow sinus may form a (usually relative) contra-indication for sinus floor elevation. Absolute contra-indications are maxillary sinus diseases (tumors) and destructive former sinus surgery (like the Caldwell-Luc operation). The lateral sinus wall is usually a thin bone plate, which is easily penetrated with rotating or sharp instruments. The fragile Schneiderian membrane plays an important role for the containment of the bonegraft. The surgical procedure of preparing the trap door and luxating it, together with the preparation of the sinus mucosa, may cause a mucosa tear. Usually, when these perforations are not too large, they will fold together when turning the trap door inward and upward, or they can be glued with a fibrin sealant, or they can be covered with a resorbable membrane. If the perforation is too large, a cortico-spongious block graft can be considered. However, in most cases the sinus floor elevation will be deleted. Perforations may also occur due to irregularities in the sinus floor or even due to immediate contact of sinus mucosa with oral mucosa. Obstruction of the antro-nasal foramen is, due to its high location, not a likely complication, nor is the occurrence of severe haemorrhages since the trap door is in the periphery of the supplying vessels. Apart from these two aspects, a number of anatomical considerations are described in connection with sinus floor elevation.
Index structures and top-k join algorithms for native keyword search databases (2011)

For supporting keyword search on structured data, current solutions require large indexes to be built that redundantly store subgraphs called neighborhoods. Further, for exploring keyword search results, large graphs have to be loaded into memory. We propose a solution, which employs much more compact index structures for neighborhood lookups. Using these indexes, we reduce keyword search result exploration to the traditional database problem of top-k join processing, enabling results to be computed efficiently. In particular, this computation can be performed on data streams successively loaded from disk (i.e., does not require the entire input to be loaded at once into memory). For supporting this, we propose a top-k procedure based on the rank join operator, which not only computes the k-best results, but also selects query plans in a top-k fashion during the process. In experiments using large real-world datasets, our solution reduced storage requirements and also outperformed the state-of-the-art in terms of performance and scalability.
Development of a New Forming Process to Fabricate a Wide Range of Phantoms that Highly Match the Acoustical Properties of Human Bone (2013)

In the various stages of developing diagnostic and therapeutic equipment, the use of phantoms can play a very important role in improving the process, and help with implementation, testing and calibrations. However, devices that use different physical factors, such as MRI, Ultrasound, CT Scan, etc. require the phantom to be made with different physical properties. This thesis deals with ultrasound and it introduces a novel composite material and a new forming process to fabricate a wide range of phantoms that highly match the acoustical properties of human bones. In contrast to ex vivo tissues, the proposed material can maintain its custom designed physical and acoustical properties unchanged for long periods of time. As results, the author introduces examples of already manufactured ultrasound phantoms (i.e. human head phantom) and a novel method of simultaneous measurements of skull thickness and its sound velocity using a set of skull bone phantoms.
Web-Based Personalized IPTV Services over NGN (2008)

Internet protocol television (IPTV), one of the most emerging services, offers multimedia streaming services with security, reliability, and relevant quality of service (QoS)/quality of experience (QoE). It provides added values to all the involving players including customers and also brings technical and business challenges to those players. For IPTV services, we expect to adopt the next generation network (NGN) environment for high quality and the Web technologies for personalization to meet the customer's necessity. Web can provide an open, flexible, and agile platform. Therefore, in this paper, we propose personalized IPTV services based on Web-based open platform in NGN environment and present functional architecture for Web-based personalized IPTV services. Technical issues for deploying the proposed IPTV services using Web are also provided. The objective of this paper is to analyze the critical architectural issues for developing viable and feasible networking platform models for personalized IPTV service.
Microwave Pyrolysis of Biomass (2006)

The present study was to investigate the microwave-assisted pyrolysis of corn stovesunder different conditions. The process yielded syngas, bio-oils, and solid charcoals. Under ourexperimental conditions, a power input level above 300 W was necessary to initiate thermal pyrolysisof corn stover. The degradation of solid corn stover increased with increasing microwave power. Ahigher power input also favored syngas production. Adding 1% pyrolytic charcoal residue to the cornstover increased the yields, particularly the liquid fraction yield. Addition of NaOH to the corn stoveras catalyst increased the syngas yield greatly. The chemical profiles of the syngas and bio-oils weredetermined using GC and GC-MS. This study demonstrated that microwave pyrolysis can beoptimized to produce high value syngas and liquid fuels and activated carbons.

Developing a data quality framework for asset management in engineering organisations (2007)

Data Quality (DQ) is seen as critical to effective business decision-making. However, maintaining DQ is often acknowledged as problematic. Asset data is the key enabler in gaining control of assets. The quality asset data provides the foundation for effective Asset Management (AM). Researches have indicated that achieving AM DQ is the key challenge engineering organisations face today. This paper investigates the DQ issues emerging from the unique nature of engineering AM data. It presents an exploratory research of a large scale national-wide DQ survey on how Australian engineering organisations address DQ issues, and proposes an AM specific DQ framework.
Scaling Limits of Electrostatic Nanorelays (2013)

A model to explore the scaling limits of electrostatically actuated nanorelays is presented, which shows that adhesion in a nanorelay's contact interface limits its performance with respect to operating voltage, contact resistance, and switching energy. For logic applications, we show that an ultimately scaled relay can be more efficient than conventional metal-oxide-semiconductor devices if (1) it is designed with very high contact resistances, leading to ≈ 1-MHz operation due to large RC delays, or (2) its actuation area is extremely large compared with its contacting area, leading to very low voltage operation, which reduces overall CV <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> losses. We propose new relay scaling relations that account for the scaling of contact interfaces.
