3-D Localization of Human Based on an Inertial Capture System (2013)

This paper introduces a method to track the spatial location and movement of a human using wearable inertia sensors without additional external global positioning devices. Starting from the lower limb kinematics of a human, the method uses multiple wearable inertia sensors to determine the orientation of the body segments and lower limb joint motions. At the same time, based on human kinematics and locomotion phase detection, the spatial position and the trajectory of a reference point on the body can be determined. An experimental study has shown that the position error can be controlled within 1-2% of the total distance in both indoor and outdoor environments. The system is capable of localization on irregular terrains (like uphill/downhill). From the localization results, the ground shape and the height information that can be recovered after localization experiments are conducted. A benchmark study on the accuracy of this method was carried out using the camera-based motion analysis system to study the validity of the system. The localization data that are obtained from the proposed method match well with those from the commercial system. Since the sensors can be worn on the human at any time and any place, this method has no restriction to indoor and outdoor applications.
Chicken industry strategies for control of tumor virus infections (1998)

Marek's disease (MD) and lymphoid leukosis (LL) are two distinct viral diseases that cause tumor mortality in chickens. Marek's disease, being horizontally transmitted, is controlled through biosecurity measures and vaccination. Prevention of early exposure before vaccine immunity is established is most important. Some multi-house growing farms have converted to all single-age placements to break the ongoing cycle of transmission. Vaccination against MD involves either in ovo or day-old administration of live vaccine, including single or multiple serotype products. Field viruses appear to adapt over time and become resistant to the prevalent vaccine. The Rispens vaccine (CVI-988) has shown good efficacy against recently emerging very virulent MD strains in the U.S. Genetic resistance of the host to MD and control of other immunosuppressive diseases also affects MD susceptibility. Lymphoid leukosis is primarily vertically transmitted and therefore controlled by elimination of shedder hens at the primary breeder level. Depending upon the genetic type, commercial performance of laying hens may be greatly improved by eradication of the LL virus from the breeding stock.

Kinetics of Alkaline Hydrolysis of Indomethacin in the Presence of Surfactants and Cosolvents (1990)

The effect of nonionic and ionic surfactants as well as water-miscible cosolvents on the alkaline hydrolysis of indomethacin was investigated. Degradation in the presence and absence of surfactants was found to follow pseudo first-order kinetics. The nonionic surfactant, polysorbate 80, produced a 7-fold increase in the stability of indomethacin. The ionic surfactants, cetrimonium bromide, benzalkonium chloride and sodium lauryl sulphate, also resulted in an increase in the stability of indomethacin but to a lesser extent than polysorbate 80. The order of surfactants in increasing the stability of indomethacin was: polysorbate 80 > sodium lauryl sulphate > benzalkonium chloride > cetrimonium bromide. Polyethylene glycol 400 was found more effective than glycerin and propylene
Abnormal Glucose Counterregulation in Insulin-dependent Diabetes Mellitus: Interaction of Anti-Insulin Antibodies and Impaired Glucagon and Epinephrine Secretion (1983)

To evaluate the roles of counterregulatory hormones and insulin antibodies in the impairment of plasma glucose recovery from hypoglycemia in diabetes mellitus, and to assess the relationship between the glucagon response and duration of the disease, 21 insulin-dependent diabetic patients and 10 nondiabetic subjects were studied. The diabetics consisted of 5 patients with recent onset of diabetes (less than 1 mo); 11 with 2.6 +/- 0.3 (mean +/- SEM) yr duration of diabetes, 5 of whom had insulin antibodies; and 5 patients with long-term diabetes (21 +/- 3 yr), insulin antibodies, and autonomic neuropathy. During insulin-induced hypoglycemia (28 mU/m2 X min for 60 min) in patients with recent-onset diabetes, plasma free insulin, glucose, and counterregulatory hormone concentrations did not differ from those of nondiabetic subjects. In patients with insulin antibodies, the disappearance of insulin after insulin infusion was delayed, and both restitution of normoglycemia and plasma glucagon response were blunted compared with patients without antibodies. When glucagon was infused (80-130 ng/m2 X min) during hypoglycemia in diabetics with impaired glucagon responses in order to simulate normal glucagon responses, plasma glucose recovery was normalized in patients without antibodies but not in those with antibodies. In patients with long-standing diabetes, restitution of normoglycemia was further impaired and this was associated with an absent plasma glucagon response and a diminished plasma epinephrine response. Plasma glucagon responses to hypoglycemia were inversely correlated to the duration of diabetes (r = -0.943; P less than 0.0005). It is concluded that impaired A-cell secretion is the predominant mechanism for the delayed glucose recovery after hypoglycemia in diabetic patients without insulin antibodies and normal epinephrine responses. Slowed disappearance of insulin due to the presence of insulin antibodies further delays the restoration of normoglycemia. Patients with long-standing diabetes and autonomic neuropathy exhibit decreased epinephrine secretion, which leads to an additional retardation of glucose recovery. Since plasma glucagon and epinephrine responses to hypoglycemia were normal at the onset of diabetes but diminished in long-term diabetes, it appears that the impaired glucagon and epinephrine responses to hypoglycemia are acquired defects that develop subsequent to B-cell failure.
Group-oriented multiuser beamforming-OFDM for different QoS requirement (2011)

In this paper, we consider the group oriented beamforming taking into account the quality of service (QoS) requirement for multimedia applications in multiuser/multi-rate OFDM system. The aim of this paper is to find the scheme for maximizing the system throughput while guarantee the QoS requirements and fairness for all services. The simulation result indicates that this scheme proposed in this paper has a higher improvement for the system performance and power utilization regarding to BER and throughput.
Microcontroller based bidirectional buck–boost converter for photo-voltaic power plant (2017)

A common configuration for a stand-alone PV power system may consist of three converters: a buck converter for the PV panelto charge the battery, a boost converter for the battery to discharge to the load and one for the load voltage regulation. Such a systemrequires a coordinated control scheme for three converters which can be complicated. A simple structure for a stand-alone PV plantconsists of a PV array, a battery unit, and its associated bidirectional converter which is a combination of a buck and boost converter.When controlled properly the system can provide uninterrupted power to the load, despite the intermittent availability of sunlight. Inthis paper complete design of the converter is carried out and the simulation has been performed using Psim. From the simulation,the graphs are presented to show the converter working in buck mode and boost mode. Controller is designed to take care of modetransition, buck to boost and boost to buck mode automatically based on source voltage. Hardware implementation has been doneusing microcontroller (8051).
Sensor placement for lifetime maximization in monitoring oil pipelines (2010)

Wireless sensor networks (WSNs) have been widely deployed and it is crucial to properly control the energy consumption of the sensor nodes to achieve the maximum WSNs' operation time (i.e., lifetime) as they are normally battery powered. In this paper, for sensor nodes that are utilized to monitor oil pipelines, we study the linear sensor placement problem with the goal of maximizing their lifetime. For a simple equal-distance placement scheme, we first illustrate that the result based on the widely used ideal power model can be misleading (i.e., adding more sensor nodes can improve WSN's lifetime) when compared to that of a realistic power model derived from Tmote Sky sensors. Then, we study equal-power placement schemes and formulate the problem as a MILP (mixed integer linear programming) problem. In addition, two efficient placement heuristics are proposed. The evaluation results show that, even with the Tmote power model, the equal-power placement schemes can improve the WSN's lifetime by up to 29% with properly selected number of sensor nodes, the distance between them and the corresponding transmission power levels. Moreover, one heuristic scheme actually obtains almost the same results as that of MILP, which is optimal. The real deployment in one oil field is also discussed.
Computer-assisted Pronunciation Teaching based on Automatic Speech Recognition (1997)

Pronunciation teaching methods, as a part of computer assisted language learning systems, are currently limited in their ability to produce feedback on pronunciation quality. After an overview of previous work on pronunciation teaching, this article presents a pronunciation scoring algorithm based on automatic speech recognition, whereby scores at a phonemic level can be calculated. These &quot;goodness of pronunciation&quot; scores consist of a likelihood ratio between forced alignments and a maximum likelihood monophone loop. The results of evaluation experiments demonstrate the method&apos;s capability of detecting both individual mispronunciations as well as to give a general assessment of which sounds a student tends to pronounce badly. 1 Introduction 1.1 Aspects of Pronunciation Teaching Before methods of computer-assisted pronunciation teaching can be devised, it is important to recognise the specific difficulties encountered in pronunciation teaching: ffl Explicit pronunciation teaching r...
Polarization bistability in semiconductor lasers (1985)

A new kind of optical bistability, the polarization bistability, is observed in InGaAsP/InP lasers operating near the polarization transition temperature. This bistability is characterized by large hysteresis loops in the polarization-resolved power versus current characteristics. Fast switching between the two stable polarization states by injection of current pulses is also demonstrated.
Lessons from History: The Great Engineering Eras (1994)

Professional engineers in Australia in the 1990s have to cope with technological and social change that involves different ways of thinking about their roles as members of a profession, and with great social change in the organisation of engineering work. Engineering-based organisations and the professional engineering occupation are systems in transition. The decade of the 1990s is leading the engineering profession into a new era that is likely to exhibit many differences from the past. The knee of the curve of change was about 1980. From that time professional engineering work organisation changed drastically, especially in managerial and leadership roles as rationalist ideologies have wrought many changes that impact adversely upon the ability of engineers to practise effectively.
Using Information from Tradinig in Trading and Portfolio Management (1995)

The EvA study is a European Union-funded project under the Seventh Framework Programme (FP7), which aims at defining new markers for chronic obstructive pulmonary disease (COPD) and its subtypes. The acronym is derived from emphysema <i>versus</i> airway disease, indicating that the project targets these two main phenotypes of the disease. The EvA study is based on the concept that emphysema and airway disease are governed by different pathophysiological processes, are driven by different genes and have differential gene expression in the lung. To define these genes, patients and non-COPD controls are recruited for clinical examination, lung function analysis and computed tomography (CT) of the lung. CT scans are used to define the phenotypes based on lung density and airway wall thickness. This is followed by bronchoscopy in order to obtain samples from the airways and the alveoli. These tissue samples, along with blood samples, are then subjected to genome-wide expression and association analysis and markers linked to the phenotypes are identified. The population of the EvA study is different from other COPD study populations, since patients with current oral glucocorticoids, antibiotics and exacerbations or current smokers are excluded, such that the signals detected in the molecular analysis are due to the distinct inflammatory process of emphysema and airway disease in COPD.
Context discovery in ad-hoc networks (2011)

With the rapid development of wireless technology and portable devices, mobile adhoc networks (MANETs) are more and more present in our daily life. Ad-hoc networks are often composed of mobile and battery-supplied devices, like laptops, mobile phones, and PDAs. With no requirement for infrastructure support, MANETs can be used as temporary networks, such as for conference and office environments, and for disaster areas. The disadvantage is that they usually have limited bandwidth and that devices in ad-hoc networks have energy-constrained power supplies, which requires simple and efficient underlying communication protocols. One of the most fundamental actions that such devices in networks need to do is to find information about the environment they are operating in. To share and use the available context information in the network, devices first need to discover and locate the required information. This action is called context discovery. However, none of the existing discovery protocols can well support resource-limited fully-distributed MANETs. Therefore, in this thesis, we design and develop a new context discovery protocol for MANETs, which is called Ahoy.

Geographic Barriers Isolate Endemic Populations of Hyperthermophilic Archaea (2003)

Barriers to dispersal between populations allow them to diverge through local adaptation or random genetic drift. High-resolution multilocus sequence analysis revealed that, on a global scale, populations of hyperthermophilic microorganisms are isolated from one another by geographic barriers and have diverged over the course of their recent evolutionary history. The identification of a biogeographic pattern in the archaeon Sulfolobus challenges the current model of microbial biodiversity in which unrestricted dispersal constrains the development of global species richness.
Buprenorphine abuse : a case report. (1990)

Search for a safe and effective analgesic is long and elusive. Buprenorphine was marketed as a potent and non-addictive narcotic drug. In recent years there have been various case reports highlighting its abuse potential. As the drug will be used more widely and particularly with its use in the detoxification of heroin dependence there is an eminent possibility of its abuse at larger scale in future. Physicians should be careful in its prescription and cases of its abuse should be actively sought tor. A case report along with literature review is presented here.
Sensibility study for optimizing the classification of remote sensing time series (2007)

Sensibility studies are necessary to evaluate if an existing method is optimizable. The present method for classification of land cover uses the course of information about an observed region during one year. The progress of the natural cover of an observed region gets visible by using weekly composites of NDVI measurements. Filling this data in a diagram results in a time curve. This time series can be characterized by minimum, maximum, amplitude, average and standard deviation of the curve and by other parameters. The analysis of this values, for example by utilization of Recursive Partitioning and Regression Trees (RPART) allows a classification of the vegetation. In the sensibility study the effects of the variation of several criteria like temporal segmentation, pre-utilization of curve smoothing are analyzed. Also the impact of changing training data on the classification of specific target classes and the possibility of predicting classes are an objective of this sensibility studies. Therefore the software, developed in a dissertation at the University of Würzburg, is changed and adopted to be able to apply statistics on the input data to provide the output for the analysis.The gained knowledge shows in which extent the results can be used to optimize the existing method. This results are more interesting in the field of segmentation, harmonics, and prediction than in curve smoothing. It is indicated that the correctness of the classification changes a lot by changing the training regions and that segmentation is very a promising approach.
Intracellular Multiplication and Virulence of <i>Shigella flexneri</i> Auxotrophic Mutants (1998)

We have constructed and analyzed a group of Shigella flexneri 5 auxotrophic mutants. The wild-type strain M90T was mutagenized in genes encoding enzymes involved in the synthesis of (i) aromatic amino acids, (ii) nucleotides, and (iii) diaminopimelic acid. In this way, strains with single (aroB, aroC, aroD, purE, thyA, and dapB) and double (purE aroB, purE aroC, purE aroD, purE thyA) mutations were obtained. Although the Aro mutants had the same nutritional requirements when grown in laboratory media, they showed different degrees of virulence in vitro and in vivo. The aroB mutant was not significantly attenuated, whereas both the aroC and aroD strains were severely attenuated. p-Aminobenzoic acid (PABA) appeared to be the main requirement for the Aro mutants' growth in tissue culture. Concerning nucleotides, thymine reduced the pathogenicity, whereas adenine did not. However, when combined with another virulence-affecting mutation, adenine auxotrophy appeared to potentiate that mutation's effects. Consequently, the association of either the purE and aroC or the purE and aroD mutations had a great effect on virulence as measured by the Sereny test, whereas the purE aroB double mutation appeared to have only a small effect. All mutants except the dapB strain seemed to move within a Caco-2 cell monolayer after 3 h of infection. Nevertheless, the auxotrophs showing a high intracellular generation time were negative in the plaque assay. Knowledge of each mutation's role in attenuating Shigella strains will provide useful tools in designing vaccine candidates.
Effector functions of pathogenic Yersinia species (2007)

Pathogenic species of the genus Yersinia suppress and reorient the immune system to infect lymphatic tissues, inner organs and at times also the vasculature. For this purpose yersiniae employ a type III secretion system to translocate effector proteins (Yersinia outer proteins; Yops) into immune cells. Yops often exert unique biochemical activities for modulating the activity of Rho GTP-binding proteins, focal adhesion proteins, inflammatory pathways and cell survival/apoptosis. In this review we will put emphasis on the biochemistry, cell- and infection biology of Yersinia effector Yops.

Smart Seat Belts - Some Population Considerations Applied to Intelligent Restraint Systems (1994)

<div class="htmlview paragraph">Throughout the motorized world seat belts are now accepted and worn by the majority of front seat occupants and by an increasing proportion of rear seat passengers, and data is presented to illustrate current rates. Current seat belts and airbags have fixed characteristics, usually optimized around the 30 mph flat barrier test for airbags with an otherwise unrestrained 50th percentile male dummy, and in the case of the restrained dummy the restraints are optimized to the 35 mph NCAP crash test. Some real world population characteristics are described, particularly the ranges in sitting positions, weights, sitting heights and biomechanical tolerance variation. Some of the population characteristics of frontal crash severities are also summarized. The desirable parameters of future restraint systems which would have variable characteristics are outlined in an effort to address these population issues.</div>
