SQLbusRT : real time data distribution and storage (2007)

The techniques used nowadays in a lot of research centers processing lots of sensor data, for instance wind tunnels, are often based on traditional relational databases. In some cases, no databases are used at all. No care is taken to deliver data under real time constraints. This does not have a negative e®ect in case data
is merely stored for analysis after the measurement process has completed, but it can have disastrous e®ects when the data is needed for control of critical elements in the measurement process itself.
This report discusses a possible solution to real time delivery storage of data. It does not focus on sensor data. Instead, it should be °exible enough to suite any situation in which it is desirable to distribute data under real time constraints.
The newly created solution, carrying the name \SQLbusRT, is based on
the blackboard architecture pattern, which will be explained in this report. A comparison is made on how the architecture of the new solution matches with the blackboard architecture. The choice for the blackboard pattern is mainly for its °exibility in the addition and removal of components to and from the system. System components will be able to work on a shared storage. This shared storage is called the blackboard, giving the name to the architecture pattern.
A prototype is developed by combining readily available open source products and creating new interfaces. The open source products which are used in this project are MySQL and ORTE. MySQL is a database management system which is known for its high performance and is used on a large scale worldwide. ORTE is an implementation of the RTPS protocol, which serves as a data communication channel over Ethernet, using a publish subscribe mechanism. An explanation of
ORTE and the publish subscribe mechanism is given in this report.
This report discusses some tests which were executed to predict the performance, reliability and scalability of SQLbusRT in a simple setup. This set of tests can be extended in future research when SQLbusRT matures. The report concludes with the answer to the question whether implementing a real time data distribution and storage solution is possible using the above mentioned components, and points out new fields of research
Evaluating and improving the TCP/UDP performances of IEEE 802.11(p)/1609 networks (2008)

The IEEE 802.11(p)/1609 standard is an emerging technology for vehicular communication networks. It amends the IEEE 802.11-2007 standard and defines a new WAVE operational mode for vehicular environments. The WAVE mode utilizes a combined FDMA/TDMA scheme to manage network bandwidth. In this mode, a node must periodically switch its frequency channel between two different channels over time. Such a design may result in bandwidth wastage due to the residual time caused by channel switching. In this paper, we propose two easy-to-implement schemes to mitigate this problem and compare their TCP/UDP performances with those of the original scheme. Our simulation results provide many insights into the operations of these schemes on IEEE 802.11(p)/1609 networks and show that the proposed schemes always outperform the original scheme.
Towards dynamic trot gait locomotion: Design, control, and experiments with Cheetah-cub, a compliant quadruped robot (2013)

We present the design of a novel compliant quadruped robot, called Cheetah-cub, and a series of locomotion experiments with fast trotting gaits. The robot’s leg configuration is based on a spring-loaded, pantograph mechanism with multiple segments. A dedicated open-loop locomotion controller was derived and implemented. Experiments were run in simulation and in hardware on flat terrain and with a step down, demonstrating the robot’s self-stabilizing properties. The robot reached a running trot with short flight phases with a maximum Froude number of FR = 1.30, or 6.9 body lengths per second. Morphological parameters such as the leg design also played a role. By adding distal in-series elasticity, self-stability and maximum robot speed improved. Our robot has several advantages, especially when compared with larger and stiffer quadruped robot designs. (1) It is, to the best of the authors’ knowledge, the fastest of all quadruped robots below 30kg (in terms of Froude number and body lengths per second). (2) It shows self-stabilizing behavior over a large range of speeds with open-loop control. (3) It is lightweight, compact, and electrically powered. (4) It is cheap, easy to reproduce, robust, and safe to handle. This makes it an excellent tool for research of multi-segment legs in quadruped robots.
An Authentication based Lightweight Device Discovery (ALDD) Model for Pervasive Computing Environment (2007)

Inter device dependency and mutual cooperation of devices is a must in pervasive computing environment. This is to overcome the barriers posed by several shortcomings of pervasive environment including limited memory and computational capability, poor battery power etc. The knowledge of valid, authenticated devices is vital in this scenario to ensure security and privacy. At the same time we have to ensure that no malicious device is interacting with any other valid device. As an attempt to address this issue, we have modified the well known LPN (Learning Parity with Noise) based H-C (Human-Computer) [1-2] authentication protocol. In this paper, we have shown it to be feasible and realistic in the trusted device discovery mechanism of pervasive ad hoc network. Along with two separate models for both large and small networks, the paper presents several possible attack scenarios with their solutions.
Membrane Topology of the Human Breast Cancer Resistance Protein (BCRP/ABCG2) Determined by Epitope Insertion and Immunofluorescence (2008)

The human breast cancer resistance protein (BCRP/ABCG2) mediates efflux of drugs and organic anions across the plasma membrane. Hydropathy analysis suggests that BCRP consists of a nucleotide-binding domain (residues approximately 1-395) and a membrane-spanning domain (MSD) (residues approximately 396-655); however, its exact topology structure remains unknown. In this study, we determined the topology structure of BCRP by inserting hemagglutinin (HA) tags in its predicted hydrophilic regions of the MSD. HA-tagged BCRP mutants were expressed in HEK cells and tested for their ability to efflux mitoxantrone and BODIPY-prazosin. Polarity of the inserted tags with respect to the plasma membrane was determined by immunofluorescence. All of the mutants were expressed at levels comparable to wild-type BCRP as revealed by immunoblotting with specific antibodies against BCRP and the HA tag. Insertions at residues 423, 454, 462, 499, 529, 532, and 651 produced functional mutants, whereas insertions at residues 560, 594, and 623 resulted in mutants with significantly reduced activity and insertions at residues 387, 420, 474, and 502 completely abrogated the activity. HA tags inserted at residues 387, 474, 529, 532, 560, and 651 were localized intracellularly, whereas those inserted at residues 420, 423, 454, 499, 502, 594, and 623 revealed an extracellular location. Residue 462 was localized in a transmembrane (TM) segment. These results provide the first direct experimental evidence in support of a 6-TM model for BCRP with the amino and carboxyl termini of the MSD located intracellularly. These data may have important implications for understanding the transport mechanism of BCRP.
Gemcitabine in combination with 5-fluorouracil with or without folinic acid in the treatment of pancreatic cancer (2002)

Pancreatic cancer is one of the most frequently reported gastrointestinal tumors and has been reported to have a 5-year survival rate of < 5%. It is most commonly diagnosed at an advanced stage and until recently, the most frequently administered treatment for patients with advanced disease has been palliative 5-fluorouracil (5-FU)-based chemotherapy. However, in clinical trials, the novel antinucleoside gemcitabine is currently considered the standard of care and has demonstrated both a survival benefit over 5-FU and an improvement in disease-related symptoms in those patients with advanced disease. The current review presents an overview of recently completed and ongoing clinical trials of gemcitabine/5-FU combination therapy for pancreatic cancer. In these trials, the administration of 5-FU varied widely from bolus injection to 24-hour infusion to protracted infusion over several weeks. These variations make a definitive judgment of this combination difficult, especially because the majority of the data represent only Phase I and Phase II study results. Although a recently completed randomized Phase III trial of gemcitabine plus bolus 5-FU versus gemcitabine failed to show a clinically meaningful survival benefit for the combination arm, current data indicate that other gemcitabine/5-FU combinations might provide a therapeutic advantage over gemcitabine alone. However, the results of ongoing Phase III studies must be reviewed before a definitive statement can be made regarding the value of this combination in the treatment of pancreatic cancer.
MCNP-CP: A Correlated Particle Radiation Source Extension of a General Purpose Monte Carlo N-Particle Transport Code (2006)

An extended version, MCNP-CP, of the general purpose Monte Carlo N-Particle transport code MCNP4c was created. It allows performing calculations with a source of correlated nuclear particles based on the Evaluated Nuclear Structure Data File ENSDF. Owing to the implemented versatile pulse height tally coincidence/anticoincidence modes, MCNP-CP presents wide possibilities for the calculation and optimization of the performance of single-detector as well as multi-detector systems for measurements with real radiation sources. The chapter gives a brief description of MCNP-CP features and presents a number of examples of its application to modeling responses of typical spectrometry systems.
MBA Marketing Education in the 21<sup>st</sup>Century: The Challenges from Technology (1999)

As the new millenium begins, forces are at work that have fundamentally changed, and will continue to fundamentally change, the way business is conducted throughout the world. These forces have been well documented, and some of the most powerful changes involve the incredible pace of technological upheaval that has spread throughout the globe. While educators observe these forces at work, business practitioners face them daily, and feel a sense of true urgency. It is critical that academics work to get in front of the changes that are buffeting business as the 21st century approaches, since failure to do so will challenge the value of academic contribution to business practice. The purpose of this paper is to articulate some of the challenges that are faced by marketing academics in their role as graduate educators as we enter the new millenium. Specific attention is paid to that force which is likely to have the most profound effect on both marketing graduate education, and marketing practice, in the first decades of the 21st century: technological upheaval in general, and Internet-based technology in particular.
Global maritime surveillance with satellite-based AIS (2009)

A space based receiving system for signals of the automatic identification system (AIS) will extend the coverage of the existing ground network, which is limited to the coastal zone (30-50 nautical miles) to open seas. With newly available satellite-based AIS receivers, the complete global ocean shipping fleet of about 60,000 ships (AIS Class A) can be tracked. The safe processing and distribution of satellite-based AIS messages to authorized users by a public traffic monitoring centre will contribute to a significantly enhanced maritime safety and security.
[Generalized tendomyopathy. I: Clinical aspects, follow-up and differential diagnosis]. (1990)

Generalized tendomyopathy (GTM), or fibromyalgia, is a disorder characterized by diffuse pain in the musculoskeletal apparatus which usually begins at a single site, e.g., as low-back pain or cervical syndrome, and develops into generalized pain over months or years. It is accompanied by increased tenderness at characteristic tender points, although the pain threshold on the whole is reduced. In addition to the main symptoms (pain in the musculoskeletal system, tenderness at the tender points), autonomic and functional symptoms are almost invariably present and are often accompanied by pathological psychological findings such as neuroses and depression. To date, no reliable laboratory parameters or pathognomonic histological findings have been identified. The disorder affects primarily women, beginning around the age of 35 and reaching its peak during or after the menopause. It also affects young people and those over age 60, although it is much less common in these cases. Secondary forms are observed particularly in rheumatoid arthritis. The differential diagnosis must first distinguish primary GTM from the secondary forms. There must also be further differentiation between internal and psychiatric disorders and primary GTM. This can be achieved in many cases by careful clinical diagnosis, although a more complete examination is sometimes required.
Preparation and Performance Study of Sialon‐Si <sub>3</sub> N <sub>4</sub> ‐SiC Composite Ceramics for Concentrated Solar Power (2014)

For lowering the sintering temperature of silicon carbide ceramics used for solar thermal energy storage technology, O'‐Sialon and silicon nitride were employed as composite phases to construct Sialon‐Si 3 N 4 ‐SiC composite ceramics. The composite ceramics were synthesized using SiC, Si 3 N 4 , quartz, and different alumina sources as starting materials with noncontact graphite‐buried sintering method. Influences of alumina sources on the physical properties and thermal shock resistance of the composites were studied. The results revealed that the employment of O'‐Sialon and silicon nitride could decrease the sintering temperature greatly to 1540°C. The optimum formula G2 prepared from mullite as alumina source achieved the best performances: 66.7 MPa of bending strength, 10.0 W/(m·K) of thermal conductivity. The composition parameter x = 0.4 of O'‐Sialon decreased to 0.04 after 30 cycles thermal shock, and the bending strength increased with a rate of 11.0% due to the increase of O'‐Sialon grain size, and the optimization of microstructure caused by the transformation of O'‐Sialon grains and densification within the samples. The good thermal shock resistance makes the composites suitable for the use as thermal storage materials of concentrated solar power generation.
Stability of Drug Additives to Peritoneal Dialysate (1995)

Drug additives in peritoneal dialysate, singly or combined, should be avoided unless data are available to support their stability. Additives should be made as close as possible to the time of the exchange. Alternatively, additives should be stored refrigerated, then warmed prior to use. The practice of preparing numerous bags at one time should be avoided. Finally, stability data do not indicate sterile integrity of the dialysate.

Endless polarisation control in coherent optical communications (1986)

An endless polarisation control system is presented which transforms a given state of polarisation (SOP) into any desired one. It features four birefringent SOP control devices of only two different types. A microprocessor-based system in a heterodyne experiment confirms the theory.
Recent Progress in Natural Products as DPP-4 Inhibitors (2015)

Diabetes mellitus is a chronic disease affecting patients' daily life and increasing patients' risk of other complication. Dipeptidyl peptidase-4 (DPP-4) is a serine aminopeptidase, which is one of the validated targets for Type 2 diabetes therapy due to its regulatory effect of incretin hormone. Seven DPP-4 inhibitors are commercially available nowadays on the market as Type 2 diabetes drugs. They are all chemically synthesized compounds with good therapeutic effects, but long-term safety remains unknown. On the other hand, nature provides a rich source for search of desired safe and effective medications; and actually more than half of the drugs on market are natural product related. Therefore, a systematic search for new DPP-4 inhibitors from nature sources seems to be of great utility for developing novel antidiabetic drugs. This review summarized recent progress of DPP-4 inhibitors from natural products, revealed that both pure natural products and the crude extracts of herbs or the hydrolyzates of proteins are active as DPP-4 inhibitors. Therefore, both could be served as useful clues for developing next generation of antidiabetes medicines via inhibiting DPP-4 activity.
Canine osteoarthritis and treatments: a review (2015)

Arthritis is a commonly occurring chronic illness in human and animals alike. Among all domestic and pet animal species, dogs suffer from arthritis more often because of excessive running or exercise, injury, and/or genetic predisposition. Presently, one in four of 77.2 million pet dogs in the United States are diagnosed with some form of arthritis. In dogs, osteoarthritis is more common than rheumatoid arthritis and pain is the number one observation. Osteoarthritis, also known as degenerative joint disease, is a slowly progressive inflammatory disease, which is characterized by degeneration of the cartilage, hypertrophy of bone at the margins, and changes in the synovial membrane, and that eventually results in pain and stiffness of joints. Alterations in joint structures, decreased flexibility, and severe pain ensues, due to lack of hydration and inflammation. Cells within the damaged joints release pro-inflammatory cytokines, which further the inflammatory process. This causes more breakdown of the cartilage collagen type II and proteoglycans, which results in a perpetual destructive cycle. This perpetuating cycle ultimately results in cartilage destruction, subchondral bone thickening, and synovial membrane inflammation. This review focuses on osteoarthritis, the disease, causes, treatments, and presents a glimpse of some new therapies under study.

Efficient computation of steady states in large-scale ODE models of biochemical reaction networks (2019)

In systems and computational biology, ordinary differential equations are used for the mechaÂnistic modelling of biochemical networks. These models can easily have hundreds of states and parameters. Typically most parameters are unknown and estimated by fitting model output to observation. During parameter estimation the model needs to be solved repeatedly, sometimes millions of times. This can then be a computational bottleneck, and limits the employment of such models. In many situations the experimental data provides information about the steady state of the biochemical reaction network. In such cases one only needs to obtain the equilibrium state for a given set of model parameters. In this paper we exploit this fact and solve the steady state problem directly rather than integrating the ODE forward in time until steady state is reached. We use Newton's method-like some previous studies- A nd develop several improvements to achieve robust convergence. To address the reliance of Newtons method on good initial guesses, we propose a continuation method. We show that the method works robustly in this setting and achieves a speed up of up to 100 compared to using ODE solves.
Safety of Hydroxocobalamin in Healthy Volunteers in a Randomized, Placebo-Controlled Study (2006)

Timely intervention for acute cyanide poisoning could entail administration of an antidote in the prehospital setting based on a presumptive diagnosis. Results of this placebo-controlled study in healthy volunteers corroborate previous studies and French postmarketing experience in cyanide-exposed patients in suggesting that the safety profile of hydroxocobalamin is consistent with prehospital or hospital use.
Prior contest experience exerts a long-term influence on subsequent winner and loser effects (2011)

These results suggest that the value to the fish of information from a recent win or loss depends on the outcome of their past contests and show that contest experience has a long-term effect on contest behavior.
Three-level space vector PWM in low index modulation region avoiding narrow pulse problem (1994)

In using GTO, a few hundreds micro seconds longer than specified pulse width must be guaranteed for safety for each device to commutate with its inherent gate current sequences. This paper describes the mechanism of generating undesirable narrow pulses in conventional three-level space vector PWM inverters and suggests two new algorithms of space vector PWM using nonnearest three and four vectors in a control period to avoid such a narrow pulse problem. Experimental verifications for the suggested algorithms are also presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Turbo Linear Dispersion Space Time Coding for MIMO HSDPA Systems (2003)

This work considers the application of Linear Dispersion (LDC) space time codes in the High Speed Downlink Packet Access (HSDPA) service of UMTS. A high rate, multiple input multiple output (MIMO) system using multiple codes, as well as channel coding and LDC space time (ST) coding is proposed. The iterative receiver consists of a soft input and soft output (SISO) demodulator, followed by a SISO decoder. The demodulator is based on the well known linear multiuser detector. Simulation results in realistic frequency selective Third Generation Partnership Project test cases reveal good performance even for high rate HSDPA services.
Spin-dependent electron transport in ferromagnetic bilayers: Application to three-dimensional spin detectors (2002)

A general analysis of spin-polarized electron transmission through ferromagnetic bilayers is presented. We calculate the transmitted current through two consecutive layers with in-plane magnetizations and we investigate the particular case where these magnetizations are orthogonal. We show that it is possible to obtain a three-dimensional spin detector for low-energy electrons which is compact and performant.
Matlab/Simulink-Based Transient Stability Analysis Of A Sensorless Synchronous Reluctance Motor (2010)

This paper deals with stability analysis for synchronous reluctance motors drive. Special attention is paid to the transient performance with variations in motor's parameters such as Ld and Rs. A study of the dynamic control using d-q model is presented first in order to clarify the stability of the motor drive system. Based on the experimental parameters of the synchronous reluctance motor, this paper gives some simulation results using MATLAB/SIMULINK software packages. It is concluded that the motor parameters, especially Ld, affect the estimator stability and hence the whole drive system.
