Adaptive Temporal Radio Maps for Indoor Location Estimation (2005)

In this paper, we present a novel method to adapt the temporal radio maps for indoor location estimation by off-setting the variational environmental factors using data mining techniques and reference points. Environmental variations, which cause the signals to change from time to time even at the same location, present a challenging task for indoor location estimation in the IEEE 802.11b infrastructure. In such a dynamic environment, the radio maps obtained in one time period may not be applicable in other time periods. To solve this problem, we apply a regression analysis to learn the temporal predictive relationship between the signal-strength values received by sparsely located reference points and that received by the mobile device. This temporal prediction model can then be used for online localization based on the newly observed signal-strength values at the client side and the reference points. We show that this technique can effectively accommodate the variations of signal-strength values over different time periods without the need to rebuild the radio maps repeatedly. We also show that the location of mobile device can be accurately determined using this technique with lower density in the distribution of the reference points.
A TMS320C53 based enhanced forward error correction scheme for US digital cellular radio (2003)

An enhanced forward error correction scheme is presented that complies with the USA digital cellular (USDC) standard. The proposed scheme use a generalized Viterbi algorithm (GVA) based on the work of N. Seshadri and C.-E.W. Sundberg (see Proc. GLOBECOMM 89, p43.3.1-4, 1989) that produces an ordered list of N global best estimates of the transmitted sequence. An algorithm is described that uses GVA to enhance performance of the USDC voice channel decoder. The algorithm is implemented on a fixed-point digital signal processor, TMS320C53. It is shown that the TMS320C53 implementation of the algorithm does not require significant increase in computational overhead when compared to a standard Viterbi algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Reinforcement Learning Based Resource Management Approach for Time-critical Workloads in Distributed Computing Environment (2018)

Many data analyzing applications highly rely on timely response from execution, and are referred as time-critical data analyzing applications. Due to frequent appearing of gigantic amount of data and analytical computations, running them on large scale distributed computing environments is often advantageous. The workload of big data applications is often hybrid, i.e., contains a combination of time-critical and regular non-time-critical applications. Resource management for hybrid workloads in complex distributed computing environment is becoming more critical and needs more studies. However, it is difficult to design rule-based approaches best suited for such complex scenarios because many complicated characteristics need to be taken into account.Therefore, we present an innovative reinforcement learning (RL) based resource management approach for hybrid workloads in distributed computing environment. We utilize neural networks to capture desired resource management model, use reinforcement learning with designed value definition to gradually improve the model and use ε-greedy methodology to extend exploration along the reinforcement process. The extensive experiments show that our obtained resource management solution through reinforcement learning is able to greatly surpass the baseline rule-based models. Specifically, the model is good at reducing both the missing deadline occurrences for time-critical applications and lowering average job delay for all jobs in the hybrid workloads. Our reinforcement learning based approach has been demonstrated to be able to provide an efficient resource manager for desired scenarios.
Electrical properties of carbon nanotubes/WS2 nanotubes (nanoparticles) hybrid films (2016)

DC and AC electrical properties of hybrid films, consisting of carbon nanotubes and tungsten disulfide nanotubes (and fullerene like nanoparticles) were studied within the 2 -300 K temperature range and over the 20 Hz -1 MHz frequency range. The temperature dependences of the resistance R(T) exhibit behavior typical for the fluctuation-induced tunneling model in the intermediate temperature range. Analysis of the dependences of real and imaginary components of the impedance on the frequency (Z'(f ) and Z"(f )) demonstrates the rising role of the contact barriers between carbon nanotubes inside hybrid films, consisting of the carbon nanotubes and inorganic tungsten disulfide nanotubes as the temperature was decreased. The active component of the impedance was found to prevail in the AC electrical properties of the hybrid films, consisting of multi-wall carbon nanotubes and WS 2 nanoparticles over the entire available temperature range.
PHASE-RELATIONS IN THE SYSTEM BAO-ND2O3-B2O3 (B2O3-GREATER-THAN-OR-EQUAL-TO-50 MOL-PERCENT) AND CRYSTAL-GROWTH OF NDBAB9O16 (1994)

The phase relations at a temperature below ''sub-solidus'' in the system BaO-Nd2O3-B2O3 (greater-than-or-equal-to 50 mol%) are investigated by means of X-ray diffraction (XRD) and differential thermal analysis (DTA). Four pseudobinary diagrams, BaB2O4-NdBO3, NdBO3-BaO.4B2O3, BaB2O-4-NdBaB9O16 and NdB3O6-NdBaB9O16, have been drawn experimentally. Specimens were prepared from various compositions of BaCO3, Nd2O3 and B2O3, of purity 99.99%, 99.95% and 99.99%, respectively, and fired at 850-degrees-C. Under the present synthesizing conditions, only one ternary compound, NdBaB9O16, was identified in this system. Powder diffraction data of NdBaB9O16 are given. Crystal growth and optical properties of NdBaB9O16 are investigated.

Recent advances in the study of the taxonomy, pathogenicity, and infectious syndromes associated with the genus Aeromonas (1991)

Over the past decade, the emergence of Aeromonas species as bona fide human pathogens and their probable role as etiologic agents of bacterial gastroenteritis have resulted in an explosion of scientific interest in the genus. Major accomplishments occurring in this field during that interval include a more refined taxonomy, identification of new cell-associated factors (surface layers, pili), and the molecular analysis of selected extracellular gene products that may play a critical role in pathogenesis (hemolysins, enterotoxins). This review provides an updated overview of recent systematic, clinical, and pathophysiologic advances and defines key areas of medical and scientific interest in which major questions remain unanswered.

Aerosol granulocyte-macrophage colony-stimulating factor for pulmonary alveolar proteinosis (2006)

Recently, granulocyte-macrophage colony-stimulating factor (GM-CSF) auto-antibodies have been found in many patients with pulmonary alveolar proteinosis (PAP). The present study reports a retrospective case series of patients who used aerosolised GM-CSF in the treatment of idiopathic PAP. Between 1999 and 2003, 12 patients elected to receive aerosolised GM-CSF (250 microg b.i.d. every other week) in lieu of whole-lung lavage or observation. Patient characteristics, pulmonary function tests, arterial blood gas analysis, laboratory values and chest radiographs were extracted from the patient's medical records. Of the six patients tested, all had GM-CSF neutralising antibodies. Additionally, abnormalities in GM-CSF gene expression (one patient), receptor expression (two patients) and ability to upregulate adhesion molecules (one patient) were found. All patients except one had a positive response (mean improvements in arterial oxygen tension, alveolar-arterial oxygen gradient, carbon monoxide diffusing capacity of the lung and forced vital capacity were 17.1 mmHg, 18.4 mmHg, 16.6% pred and 13.5% pred, respectively). Two patients made a complete recovery and were disease free 1 and 2 yrs after discontinuing treatment. Four patients showed complete response to both the initial course or when treated again for recurrence after discontinuation of treatment. One patient required dose escalation (500 microg b.i.d.) with complete response. GM-CSF was well tolerated without late toxicity after median (range) follow-up of 30.5 (3-68) months. In conclusion, aerosolised granulocyte-macrophage colony-stimulating factor is safe and effective in treating pulmonary alveolar proteinosis providing an alternative to whole-lung lavage or subcutaneous granulocyte-macrophage colony-stimulating factor.
SOME FACTORS AFFECTING GELATION OF FROZEN EGG YOLKa, b (1954)

Freezing at temperature below −6° C (21°F) produces irreversible physico- chemical changes (gelation) in egg yolk. Colloid milling of yolk inhibited gelation to a large extent. None of the many chemical substances examined inhibited gelation and produced a yolk of normal flavor. Very quick freezing combined with rapid thawing had a pronounced gelation inhibiting effect. Frozen shell eggs that were defrosted by dielectric heating did not thaw uniformly.
Nanolipid carrier-based thermoreversible gel for localized delivery of docetaxel to breast cancer (2013)

Intratumoral and intralesional administration of anticancer drugs in gels and implantable formulations is gaining much importance on account of its advantage of site-specific delivery with highly dependable freedom from unwanted side effects. Nanolipid carriers (NLC) are the preferred vehicle due to their improved properties particularly drug loading. In the present investigation, glyceryl monostearate-oleic acid NLCs loaded with docetaxel were prepared by emulsification and ultrasonication technique and were incorporated in thermoreversible pluronic F127 gel (TRPgel) for intralesion injection to breast tissue. The NLCs were spherical particles of 113 nm size with a negative zeta potential of -32.8 and 85 % drug entrapment. In vitro drug release profile of the NLC showed 96 % drug release in 48 h following Higuchi release kinetics. NLC incorporated TRPgel showed mucoadhesive force of 3.07 dynes/cm<sup>2</sup> and gelling temperature in the range of 32 to 37 °C. The drug entrapped gel was also subjected to in vitro cytotoxicity study in human B-16 and HeLa cell lines by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and in vivo drug distribution study in breast tissue in healthy Wistar rats. The MTT assay revealed that docetaxel-loaded NLC incorporated into gel showed lower cytotoxicity than docetaxel. However, in vivo breast tissue distribution studies showed high tissue drug concentration, sustained over a period of 60 h in comparison to docetaxel and docetaxel-loaded NLCs. These results suggest that nanolipid carrier of docetaxel in TRPgel could be a promising carrier system to deliver drug to tumor by intralesional administration for improving therapeutic benefits of docetaxel.

Lactose-Poly(ethylene Glycol)-Grafted Poly-<scp>l</scp>-Lysine as Hepatoma Cell-Targeted Gene Carrier (1998)

To investigate the delivery of DNA into cells, lactose-poly(ethylene glycol)-grafted poly-L-lysine (Lac-PEG-PLL) polymers were synthesized as polymeric gene carriers. The new synthetic carriers, varying the substitution ratio of lactose-poly(ethylene glycol) (lactose-PEG), were characterized by NMR spectroscopy and size-exclusion chromatography. Electrophoretic mobility assay confirmed that the new gene carrier makes a complex with plasmid DNA. The attached poly(ethylene glycol) gives better solubility properties to gene/carrier complex. Transfection experiments showed that Lac-PEG-PLL efficiently delivers DNA to a hepatoma cell line in vitro; the best efficiency was achieved at a 1:3 weight ratio of DNA to carrier. As the lactose-PEG substitution content increased up to 30%, the transfection efficiency increased, which demonstrates that the lactose serves as a targeting moiety. No considerable cytotoxicity was observed due to Lac-PEG-PLL or its complex with DNA within the concentration range for this experiment. The use of chloroquine increased transfection efficiency that indicates the involvement of hydrolytic degradation of the system in lysosome. It is likely that plasmid DNA/Lac-PEG-PLL complexes enter the cells through a receptor-mediated endocytosis mechanism. These results show that Lac-PEG-PLL can form a complex with plasmid DNA and serve as an efficient gene delivery carrier with lower cytotoxicity compared to that of poly-L-lysine. Therefore, it is expected that our Lac-PEG-PLL carrier can be used as an in vivo gene delivery vector.

Plant-Specific RETRAN Analyses in Support of Chinshan BWR/4 Operation (1998)

Two analyses for Chinshan nuclear power station (CSNPS) show the RETRAN applications in reactor operations. One was used to find the root cause of a reactor trip due to high neutron flux (APRM Hi-Hi). Two of the four turbine control valves failed and closed rapidly. Whether the pressure increase caused the APRM Hi-Hi reactor scram was questioned. An analysis was performed to determine the way to bring unit 1 back to power. The second analysis was conducted to provide an evaluation of the consequences before a plant test planned for late 1994 to consider a design change upgrading recirculation flow control. However, there were concerns about reactor scram during execution of the test and the potential of entering the exclusive region of instability. Sensitivity studies on several different combinations of initial conditions and feedwater flow coastdown curves indicated potential problems with reactor trip and stability.
Design and Spin Test of a Hybrid Composite Flywheel Rotor with a Split Type Hub (2006)

A study is conducted on lowering the radial tensile stresses and increasing the performance of the fiber wound composite flywheel rotor by applying pressure on the inner surface of the rotor using a split type hub that spreads in the radial direction due to the centrifugal force. A conventional solid or ring type hub in most cases produces tensile stresses within the rotor, possibly causing delamination and eventually lowering the maximum speed of the rotor. The relationship between the stresses of the rotor and the thickness of the hub is derived and applied to the single and hybrid rotors. A hybrid composite rotor of 180 mm inner diameter and 340 mm outer diameter is designed and fabricated, which reaches only the strength ratio of 0.58 at the maximum rotating speed of 40,000 rpm. A spin test was conducted to show the improved performance of the rotor with the split type hub by measuring the mechanical strains from the rotor. The radial and circumferential strains at four different locations are measured up to 30,000 rpm using a wireless telemetry system, and they are in good agreement with the analytical calculations. The rotor has survived a spin test of up to 40,000 rpm, which corresponds to the usable energy of at least 500 W h with the safety factor of 1.7.

Characterization of the Brillouin-loss spectrum of single-mode fibers by use of very short (<10-ns) pulses (1999)

The characterization of the Brillouin-loss spectrum of single-mode fibers with very short (<10-ns) pulses has been studied. It was found that the Brillouin-loss signal intensity is linearly related to the duration of the pump pulse used to obtain the spectrum. In contrast with the uniform trend of the signal, three distinct behaviors were observed in the spectral linewidth. At long pulse durations the linewidth was constant at approximately 40 MHz. Pulse durations of the order of the phonon lifetime resulted in a broader spectrum, reaching a maximum width of ~100 MHz at 5 ns. Reducing the pulse duration further resulted in a sudden narrowing of the Brillouin line.
Performance footprints of heavy-users in 3G networks via empirical measurement (2010)

Abstract—Cellular technology is widely used for Internet access, also because most operators are now offering Mbit/s data rates at affordable prices. Many studies analyzed the performance of these networks using analytical or simulation approaches. However, due to lack of data from operational environments, very little is known about the performance of real cellular networks. In this paper, we assess the performance of the 3G network of one of the major European telecom operators, using several recent traffic traces of TCP connections to port 80 and 8080. After presenting performance statistics related to all the network users, we focus on heavy users. To assess their performance and to uncover the related causes, we introduce an investigation approach easily repeatable in the very common situation where only data traces are available, with no other information such as mapping of users to cells, network capacity, or packet payload. Analyzingboth “single long-livedconnections” and “multiple long-lived connections”, we assess the performance of those users, providing insights on how and why performance can vary significantly over time and among different users.

Design optimization and implementation of a microgravity capacitive HARPSS accelerometer (2006)

This paper reports on the design optimization and implementation of a lateral capacitive accelerometer with high sensitivity and micro-g resolution, fabricated through the high-aspect ratio polysilicon and single-crystal silicon process on regular silicon wafers. A new implementation of vertical corrugation in silicon electrodes is developed to reduce the mechanical noise equivalent acceleration of the sensor. The predicted effect of corrugation on thermomechanical noise and also on static sensitivity is verified using ANSYS steady-state thermal simulation and FEMLAB linear stationary electrostatics analysis, respectively. The number of corrugated electrodes and the sense gap spacing is optimized to minimize the system (sensor + circuit) noise floor, while satisfying process and electronics limits. The open-loop differential sensitivity of a 60-/spl mu/m-thick prototype accelerometer is measured to be 0.25 V/g equivalent to 4.5 pF/g over a 1-g range. The estimated total noise equivalent acceleration of the system (sensor + circuit) is 0.95 /spl mu/g//spl radic/Hz in atmosphere.
How a layered rem architecture brings cognition to today's mobile networks (2012)

In this article, we present a layered radio environment map architecture along with its applications to the self-organizing network functionalities of heterogeneous LTE radio access networks comprising macrocells and femtocells. In this architecture, the functional blocks reappear with different spatial and temporal granularity at different architectural layers. Although the radio environment map is one of the key promising technologies to enable future cognitive radio networks, it can be already applied to provide limited cognitive capabilities to today's commercial networks too. We explain why, and show how, this architecture can support today’s LTE self-organizing network functions like automatic neighbor relation and minimization of drive tests, and also allow the smooth introduction of new radio access technologies through refarming. We also demonstrate some of the quantitative benefits adopting radio environment map technologies can bring using the minimization of drive tests as an example.
