Pseudonocardia benzenivorans sp. nov. (2004)

A Gram-positive, rod-shaped, non-spore-forming bacterium (B5(T)) was isolated from an enrichment culture that contained 1,2,3,5-tetrachlorobenzene as the sole source of carbon. On the basis of 16S rRNA gene sequence similarity studies, strain B5(T) was shown to belong to the family Pseudonocardiaceae and was related most closely to Pseudonocardia sulfidoxydans (98.8 %) and Pseudonocardia hydrocarbonoxydans (98.3 %). 16S rRNA gene sequence similarity to other Pseudonocardia species was <97 %. Chemotaxonomic data [major menaquinone, MK-8(H(4)); major polar lipids, diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol; major fatty acids, C(16 : 0), iso-C(16 : 0) and iso-C(15 : 0)] supported the affiliation of strain B5(T) to the genus Pseudonocardia. The results of DNA-DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain B5(T) from P. sulfidoxydans and P. hydrocarbonoxydans. Strain B5(T) therefore represents a novel species of the genus Pseudonocardia, for which the name Pseudonocardia benzenivorans sp. nov. is proposed, with the type strain B5(T) (=DSM 44703(T)=CIP 107928(T)).

Reliable and fast rerouting mechanism for a protected label switched path (2004)

We present a reliable, fast and efficient mechanism for rerouting traffic when there is a link/node failure or congestion problem in multiprotocol label switching (MPLS) networks. This proposal is able to guarantee rigorous QoS criteria for high-priority data traffic by eliminating packet loss and disorder, and minimizing packet delay. This directly translates into an improvement of important quality measure attributes, such as performance, reliability and fault tolerance, in MPLS-based networks. We use a predefined, alternative label switched path (LSP) in order to restore traffic (protection switching or fast rerouting). A theoretical model is formulated for the failure scenario in a protected LSP segment and we validate it through simulations using the MPLS network simulator (MNS). Further simulations show that our mechanism is able to eliminate packet loss and disorder completely while reducing the full restoration time. The potential cost in terms of the important issue of buffer requirements is also studied. Even for the worst case, buffer requirements are well within justifiable limits for guaranteeing QoS for high-priority data traffic in protected LSPs. The combination of these improvements helps to minimize the effects of link failure. This facilitates satisfying rigorous QoS requirements, increasing the throughput, rapid release of network resources and enhancement of the end-to-end performance of MPLS networks.
Computer control of a modified Langendorff perfusion apparatus for organ preservation using cryoprotective agents (1981)

The construction of an isolated rat heart cryopreservation apparatus which is interfaced to a process-control computer is described. The flexibility of the equipment is demonstrated by the running of simultaneous dual sets of experiments under multiple and variable conditions. The computer-control program allows interactive calibration of the instruments, accurate control of variables and modification of parameters during the experiments. By controlling the speed of the perfusate's peristaltic pump, perfusion pressure was not allowed to exceed a present level. Experiments are reported which allow the storage of hearts at -22 degrees C with the aid of the cryoprotective agents, ethylene glycol.

Switch Systems Theory Apply to the Energy Control of a Hybrid Electric Vehicle (2011)

Hybrid electric vehicles (HEVs) driving process including both continuous-time dynamic systems and the discrete event dynamic systems, is a typical hybrid system model. Based on a hybrid electric vehicle dynamics theory study, analyze the power demand of hybrid cars in the different operating modes, then construct a class of switched systems. Through the rational design of switching rules, make hybrid cars switch between the different power source in a more reasonable manner and improve the efficiency of engines and motors to meet the requirements under the premise of dynamic force, reduce the fuel consumption and reduce exhaust emissions.
Virtual display design using waveguide hologram in conical mounting configuration (2011)

An improved virtual display is proposed by using a waveguide holographic configuration with two total internal reflection holographic gratings in conical mounting and two volume hologram in classical mounting recorded on a single transparent planar waveguide. Using this compact configuration, efficiency can be dramatically improved and assembly is easy to be realized. The main principle and the method of intensity uniformity control are present in the paper. The analysis and simulation results are also explained. The virtual display system design shows good optical performance with 25 deg. field of view, a large pupil about 43 mm, little distortion less than 1%, and low aberration. The configuration can be used to a portable or wearable display.
An improvement to k-nearest neighbor classifier (2011)

Non-parametric methods like Nearest neighbor classifier (NNC) and its variants such as k-nearest neighbor classifier (k-NNC) are simple to use and often shows good performance in practice. It stores all training patterns and searches to find k nearest neighbors of the given test pattern. Some fundamental improvements to k-NNC are (i) weighted k-nearest neighbor classifier (wk-NNC) where a weight to each of the neighbors is given and is used in the classification, (ii) to use a bootstrapped training set instead of the given training set, etc. Hamamoto et. al. [1] has given a bootstrapping method, where a training pattern is replaced by a weighted mean of a few of its neighbors from its own class of training patterns. It is shown to improve the classification accuracy in most of the cases. The time to create the bootstrapped set is O(n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) where n is the number of training patterns. This paper presents a novel improvement to the k-NNC called k-Nearest Neighbor Mean Classifier (k-NNMC). k-NNMC finds k nearest neighbors for each class of training patterns separately, and finds means for each of these k neighbors (class-wise). Classification is done according to the nearest mean pattern. It is shown experimentally using several standard data-sets that the proposed classifier shows better classification accuracy over k-NNC, wk-NNC and k-NNC using Hamamoto's bootstrapped training set. Further, the proposed method does not have a design phase as the Hamamoto's method, and this is suitable for parallel implementations which can be coupled with any indexing and space reduction methods easily. It is a suitable method to be used in data mining applications.
Exchange and markets (2005)

Markets are the dominant form of economic organisation in modern societies. The main purpose of this chapter is to use demand and supply analysis to explain how markets work. It will also use that analysis to explain how the interest rate is determined, and how it influences the level of saving and investment. Before getting to those matters, we begin by discussing the benefits that can flow from exchange and specialisation, which are what markets are really all about.
Peer-to-Peer Location-Based Services based on Blockchain and Web Technologies (2017)

A distinctive feature of smart cities is the fruitful and effective interconnection among mobile users and resources, to support the fulfillment of sophisticated location-based services (LBSs).\nLBSs are increasingly taking advantage of user geographic location to provide a broad range of applications, such as traffic monitoring, social networking, emergency management and advertising.\nUnfortunately, most LBSs rely upon centralized infrastructures, thus raising, besides scalability and resilience, also serious concerns regarding user privacy.\n\nThis Ph.D. Thesis presents a new peer-to-peer overlay scheme suitable for the development of LBSs, enabling efficient peer and resource retrieval around any geographical location, while paying attention to users' privacy.\nAn important difference between the designed peer-to-peer overlay and other solutions in literature is the capability to adapt the topology of the network depending on peers' mobility.\n\nThroughout this Thesis, the designed peer-to-peer overlay has been intensively evaluated, both through simulations in various and different scenarios of mobility, and by means of field testing performed with the collaboration of several volunteers.\nFurthermore, the Thesis presents a real implementation of the peer-to-peer overlay which is released online with a free and open source software license, thus making it usable as a web application framework without restrictions.\n\nFinally, this Thesis faces the problem related to truthfulness of geographical locations stated by peers, proposing a privacy-aware approach inspired by the novel blockchain technology.\nSimulation-based evaluation of the proposed technique shows an effective and robust behavior even in presence of significant shares of deceitful peers.

Current and emerging medical therapies for glaucoma (2005)

Glaucoma is a multifactorial optic neuropathy in which there is a characteristic acquired loss of retinal ganglion cells, at levels beyond normal age-related baseline loss, and corresponding atrophy of the optic nerve. Although asymptomatic in its earlier stages, the disease is nevertheless one of the leading global causes of irreversible blindness. Although elevated intraocular pressure (IOP) is one of the most important risk factors and lowering of IOP is the only proven treatment so far, the definition of glaucoma has evolved from a disease caused by increased IOP to one characterised by an IOP-sensitive, progressive optic neuropathy. In recent years, safer and better tolerated topical medications have been developed to control IOP more effectively, thereby limiting the need for surgery. New research has also noted the importance of diurnal IOP variation as a critical risk factor for progression of glaucomatous optic neuropathy (GON) and subsequent visual field loss. Moreover, new discoveries have further elucidated the basic pathophysiological and genetic mechanisms underlying the elevated levels of IOP, as well as the cellular mechanisms of GON. As our understanding of these complex pathways continues to improve, development opportunities for new therapeutic modalities will be enhanced.
Rijke Organ: Modeling and Control of Array of Rijke Tubes (2020)

Rijke tube is a popular physical experiment demonstrating a spontaneous generation of sound in an open vertical pipe with a heat source. This laboratory instance of thermoacoustic instability has been researched due to its significance in practical thermoacoustic systems. We revisit the experiment, focusing on the possible use of the Rijke tube as a musical instrument. The novelty presented in this paper consists in shifting the goal from sound suppression to active sound generation. This called for modifying the previously investigated methods for stabilization of thermoacoustic oscillations into their excitation and control of their amplitude. On our way towards this goal, we developed a time-domain mathematical model that considers the nonlinear and time-varying aspects of the Rijke tube. The model extends the existing modeling and analysis approaches, which are mainly based in frequency domain. We also present an extension of the basic laboratory setup in the form of an array of Rijke tubes equipped with a single speaker used to control multiple Rijke tubes with different natural frequencies simultaneously.
A four step methodology for using simulation and optimization technologies in strategic supply chain planning (1999)

Supply chains are real-world systems that transform raw materials and resources into end-products that are consumed by customers. Supply chains encompass a series of steps that add value through time, place and material transformation. Each manufacturer or distributor has some subset of the supply chain that it must manage and run profitably and efficiently to survive and grow. Decisions about how to plan a company's supply-chain operations can be operational, tactical or strategic. Strategic decisions are the most far-reaching and difficult decisions to make. These decisions are characterized by complexity, interdependence and uncertainty. Simulation and optimization modeling techniques are used to help make supply-chain strategic decisions. The methodology (network optimization, network simulation, policy optimization, and design for robustness) is a proposed approach to supply-chain strategic planning that attempts to leverage the strength of multiple modeling techniques. Each step solves a different part of the master planning problem, using either optimization, simulation or simulation-optimization. By using complementary modeling approaches together in the four-step methodology, the supply-chain planner's activities and decisions can be greatly improved.
Optical Fiber Tip Pressure Sensor (2004)

Miniature pressure sensors which can endure harsh environments are a highly sought after goal in industrial, medical and research fields. Microelectromechanical systems (MEMS) are the current methods to fabricate such small sensors. However, they suffer from low sensitivity and poor mechanical properties. To fulfill the need for robust and reliable miniature pressure sensors that can operate under high temperatures, a novel type of optical fiber tip sensor only 125μm in diameter is presented in this thesis. The essential element is a piece of hollow fiber which connects the fiber end and a diaphragm to form a Fabry-Pérot cavity. The all-fused-silica structure fabricated directly on a fiber tip has little temperature dependence and can function very well with high resolution and accuracy at temperatures up to 600 °C. In addition to its miniature size, its advantages include superior mechanical properties, biocompatibility, immunity to electromagnetic interference, disposability and cost-effective fabrication. The principle of operation, design analysis, fabrication implementation and performance evaluation of the sensor are discussed in detail in the following chapters.
Strategies for the Supply of Lipid Substrates during Post-Natal Brain Development: A Tale of Two Tissues (1993)

In the suckling neonate the source of lipid and other substrates for brain development is the mother's milk. The lactating mammary gland is a highly versatile organ which is able to utilize a range of substrates for milk lipid production including glucose and ketone bodies (for de novo synthesis), triacylglycerols and non-esterified fatty acids. The composition of the milk lipid alters with changes in the substrates available to the mammary gland. The neonate has to process the milk triacylglycerols to forms (ketone bodies, medium-chain fatty acids) more suitable for extraction by the developing brain. The strategies employed to allow this flexibility in the lactating rat and its offspring are discussed.
Increased Potato Yields by Treatment of Seedpieces with Specific Strains of <i>Pseudomonas fluorescens</i> and <i>P. putida</i> (2009)

Significant increases in growth and yield of potato plants were achieved by treating seedpieces with suspensions of two <i>Pseudomonas</i> spp. at ∼10<sup>9</sup> colony-forming units (cfu)/ml prior to planting. The pseudomonads were selected from over 100 strains that were isolated from the surface of potato tubers and also exhibited antibiosis against <i>Erwinia carotovora</i> var. <i>carotovora</i> in vitro. The isolates were identified as strains of <i>Pseudomonas fluorescens</i> and <i>P. putida.</i> These strains survived for at least 1 mo on treated seedpieces planted in loamy sand field soil at populations of ∼10<sup>9</sup> cfu/0.785 cm<sup>2</sup>. Also, they colonized developing potato roots and were the predominant bacteria in the rhizospheres up to 2 mo after planting. Bacterization of seedpieces planted in field soils in the greenhouse resulted in up to 100% increase in fresh weight of shoot and root systems in a 4-wk period. Statistically significant increases in yield ranged from 14 to 33% in five of nine field plots in California and Idaho. The pseudomonads had no effect on plant growth or tuber yield when seedpieces were planted in peat soil, or in soil that was relatively dry. Both <i>Pseudomonas</i> spp. were compatible with fungicides that were commonly used to treat seedpieces, except for manganese ethylenebisdithio-carbamate zinc salt (mancozeb). The mechanism by which these bacteria enhance plant growth and tuber yield may be associated with changes in the composition of rhizosphere bacterial flora.
Studies on Acute Marek's Disease I. Characteristics of Isolate GA in Chickens (1968)

During the last 5 years, condemnations for an acute form of leukosis in young chickens have increased rapidly in the United States (11). Sevoian (4) has designated this as a Type II form of lymphoid leukosis. Biggs (1), however, classifies it as an acute form of Marek's disease (MD), in contrast to the less explosive classical form, which appears in slightly older birds with a lower incidence of visceral lesions. Under field conditions MD affects chickens primarily between 6 and 20 weeks of age; however, Sevoian et al. (6,7,8,9) report that leukosis developed consistently within 2 to 3 weeks of inoculation of day-old chicks with the JM isolate in preparations of blood, plasma, or tissue suspension, and was also transmitted by air. Biggs et al. (2) showed that isolates HPRS 16, 18, and 19 can be transmitted with blood and tumor homogenate, with the latent period being 21 to 28 days. The present study was done to: 1) report on an MD isolate found in Georgia and discuss the pathogenic aspects of this agent; 2) ascertain the optimum age for obtaining plasma from birds experimentally infected with isolate GA; and 3) compare MD in birds injected with plasma or tumor suspension for a series of 9 passages at bi-weekly intervals.
Power-cycling-stability of IGBT-modules (2002)

Insulated gate bipolar transistors (IGBT) play a leading role in industrial power converter applications. They also reach traction applications where GTOs and thyristors are the predominant switching devices. In this application, power cycling stability and temperature cycling stability are especially very important requests for the long-term stability of such switching devices. Since the mounting technology in wire bonded IGBT-modules is completely different to pressure contacted GTOs and thyristors, in this presentation a special focus is brought to the power cycling stability. Concerning this topic, customer requests are compared to the current state in power cycling stability of Siemens- and eupec-IGBT modules. Principle device structures and mounting technology as well as predominant failure mechanisms are introduced. The improvement in the power cycling stability in the last few years are demonstrated by comparing results of different mounting and bonding technologies. The power cycling test equipment and a test method which allows online monitoring during the power cycling test are shown. This method is based on the change of the forward voltage of the IGBTs caused by a change of the thermal resistance of the chips and the change of the ohmic resistance of the bond wire contact on the chip. The dependence of the IGBT-module's power cycling stability on its temperature swing as well as on its absolute temperature are demonstrated.
