An analysis of cornering stiffness of 14.00R20 tire with run-flat insert

Research results of 14.00R20 tire, equipped with „run-flat” insert, in aspect of cornering stiffness are presented in this paper. Resistance on side drift is one of the many attributes of automobile wheels tyres, which influences on the useful properties of vehicle. The tire cornering characteristics, determined basing on laboratory research results are shown. These characteristics were determined in wide rage of air inflation pressure and wheel normal load changes, also with no air pressure inside the tire, what corresponds with the case of projectile shooting through the tyre and simultanously allows the „run-flat” insert to switch into the transfer the components of driving wheel load. In the vehicles appropriated to other jobs than typical transport tasks, drive wheels with the special properties are often used. They are, for example, wheels adapted to the drive with reduced values of air pressure in the tyres in the heavy terrain conditions or wheels equiped with the insert type „run-flat”, adapted to the drive without air in tyre as a result of the penetration or projectile shot through the tire. Such wheels are for a long time used, for example, in the wheeled transporter carriers or in the armored vehicles prepared to the activities in the regions of armed conflicts. Presently, the frequent cases are known of application of „run-flat” insertions also in civilian personal vehicles, as elements for increasing the vehicle security level. Basing on cornering characteristics an analysis of tire properties were carried out. Data for tire road interaction modeling, during side cornering are shown.
Hydrodynamic effects of leading-edge tubercles on control surfaces and in flapping foil propulsion

This thesis investigates the hydrodynamic effects of biologically-inspired leading-edge tubercles. Two complementary studies examine the performance of three-dimensional hydrofoils based on the pectoral flippers of the Humpback Whale (novangilae megaptera). The first study uses a static foil, with application to conventional control surfaces– such as rudders or dive planes–found on marine vehicles. The second study uses a dynamic foil, with application to flapping foil propulsion. The lift and drag characteristics of foils with and without tubercles are compared using force measurements from experiments conducted in a water tunnel at four Reynolds numbers between 4.4 × 10 and 1.2 × 10. Results from these experiments indicate the foils stall from the trailing edge in the range of Reynolds numbers tested. Stall was delayed on the foil with tubercles; maximum lift was reduced in all cases but the highest Re. PIV flow visualization at Re = 8.9 × 10 4 showed flow separation at the trailing edge of both foils as attack angle was increased, confirming that the foils were in trailing edge stall. Surface normal vorticity in ensemble averaged flow fields showed distinct pairs of opposite sign vortical structures being generated by the tubercles, providing some insight into the fluid dynamic mechanism that leads to changes in the performance of a foil with tubercles. Tubercles were used on a flapping foil for the first time. Mean thrust coefficient, CT , power coefficient, CP , and efficiency, η, were measured over a wide parametric space. The maximum thrust coefficient and efficiency measured using the smooth control foil were CT = 3.511 and η = 0.678. The maxima using the tubercled test foil were CT = 3.366 and η = 0.663. In general, the foil with tubercles performed worse than the control, and this performance deficit grew with increased loading. These results suggest that the vortical structures generated by the tubercles interfere with the thrust wake generated by flapping, ultimately degrading performance. Thesis Supervisor: Alexandra H.

Power-cycling-stability of IGBT-modules

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.

Improving Representation of Tropical Wetland Methane Emissions With CYGNSS Inundation Maps

Wetlands are the single largest source of methane to the atmosphere and their emissions are expected to respond to a changing climate. Inaccuracy and uncertainty in inundation extent drives differences in modeled wetland emissions and impacts representation of wetland emissions on inter‐annual and seasonal time frames. Existing wetland maps are based on optical or NIR satellite data obscured by clouds and vegetation, often leading to underestimates in wetlands extent, especially in the Tropics. Here, we present new inundation maps based on the Cyclone Global Navigation Satellite System (CYGNSS) satellite constellation, operating in L‐band that is not impacted by clouds or vegetation, providing reliable observations through canopy and cloudy periods. We map the temporal and spatial dynamics of the Pantanal and Sudd wetlands, two of the largest wetlands in the world, using CYGNSS data and a computer vision algorithm. We link these inundation maps to methane fluxes via WetCHARTs, a global wetland methane emissions model ensemble. We contrast CYGNSS‐modeled methane emissions with WetCHARTs standard runs that use monthly rainfall data from ECMWF re‐analysis (ERA5), as well as the commonly used SWAMPS wetland maps. We find that the CYGNSS‐based inundation maps modify the methane emissions in multiple ways. The seasonality of inundation and methane emissions is shifted by two months because of the lag in wetland recharge following peak rainfall. Both inundation and methane emissions also respond non‐linearly to wet‐season precipitation totals, leading to large interannual variability in emissions. Finally, the annual magnitude of emissions is found to be greater than previously estimated.
Implantable Multi-panel Platform for Continuous Monitoring of Exogenous and Endogenous Metabolites for Applications in Personalized Medicine

Nowadays, scientific advances are leading to the discovery of newer, better, more targeted treatments that will improve the human health. However, despite the promising results and the major advantages in treatments offered to patients, these personalized medical treatments are limited to few cases. Translational medicine research with animals is needed to find innovative, safe and life-saving solutions for patients, especially in drug development. Although technological improvements may lead one day to the end of animal testing, today those strategies are not sufficient, due to the complexity of living organisms. The living conditions of these animals are of primary importance because high stress levels can affect the experimental results. In this respect, the monitoring of the animals in a small living space by means of a fully implantable device, can contribute to minimize the human intervention, increasing the comfort for the animals. The objective of this thesis is the design and characterization of a fully implantable biosensor array for the real-time detection of endogenous and exogenous metabolites, for the monitoring of small caged animals in drug development, and for future applications in personalized medicine. The fully implantable device consists of: a passive sensing platform consisting of an array of four independent electrochemical biosensors, together with a pH sensor and a temperature sensor for the optimization of the sensing performances in different physiological conditions; integrated circuits capable of performing multiple electrochemical measurements; a coil for remote powering of the integrated circuit and the short-range data transmission to an external device; a membrane packaging ensuring measurements with high signal-to-noise ratio, biocompatibility and selectivity against possible interfering molecules in biological fluids. â¢ In vitro monitoring of four anti-cancer drugs and an anti-inflammatory drug within the pharmacological ranges in undiluted human serum; â¢ Demonstration of the in vitro functionality of the complete system, showing that the external powering system correctly operate the device, and receive the data from the sensors; â¢ In vivo biocompatibility tests of the packaging, showing after 30 days a significant reduction of the inflammatory response in time, suggesting normal host recovery; â¢ In vivo continuous monitoring of an anti-inflammatory drug, demonstrating the proof of-concept of the system for future personalized medicine applications.

Web presence of U.S. primary wood products exporters

This Technical Note examines the use of the World Wide Web by primary wood products exporters. Data for the study were collected by a mail survey conducted in February and March of 1999, comprising 324 firms. The adjusted response rate of the survey was 45.7 percent. Results indicate that respondents used the Web mostly for promotion activities, Although value-chain and business processes are currently less frequently used on respondent websites, they are expected to experience the highest growth within the next 2 years. Using a website, respondents primarily target new customers, both foreign and domestic. Few respondents try to reach foreign audiences by addressing them in their native tongue. The study did not find that multilingual websites are likely to be more successful than English-only websites.
Neuro fuzzy robust controllers for drive systems

The authors describe and approximate zeroing with an equivalent disturbance observer and predictive controller for drive systems. Then this linear controller structure is changed by fuzzy logic such that the controller makes the system respond quickly if the error is large and vice versa in order to obtain a robust controller which is insensitive to both the plant noise and the observation noise. Next, a variable structure PI controller by fuzzy logic for the drive systems is introduced. Then, this control scheme is implemented with neural networks. These controllers are realized with digital signal processors. The experimental results are given. Lastly, the applications of neuro fuzzy methods to inverters, converters, motion controls and sensors are explained. <<ETX>>

The New Inspection Regime of the Paris Mou on Port State Control: Improvement of the System

After the Amoco Cadiz ecological disaster in France, in 1978, the Paris Memorandum of Understanding (PMoU) on Port State Control (PSC) was created. The purpose of this harmonized inspection system is to prevent substandard ships that present high risk from sailing to European and Canadian N. Atlantic ports and anchorages. The existence of many substandard ships is a well-known fact and they sail not only in European waters but all over the world; most of these substandard ships are registered in states that are very permissive in respect of regulations of design, construction, equipment, safety, working conditions, etc. The original objective of the PMoU was for each member country to inspect individually 25% of all the foreign merchant ships which enter its ports (specified MoU Ports) to identify the degree of risk. The original inspection regime of this system is going to be replaced by a New Inspection Regime (NIR), agreed in 2009. With this NIR, the PSC Committee aims to inspect all ships, i.e. the inspections will rise from 25% to 100% of foreign ships entering these ports. This New Inspection Regime would classify the ships according to thr ee categories based on the level of risk associated with the ship revealed by the inspection; once classified, that particular ship would be subjected to more or less frequent inspections. This article will focus on two aspects. The first is how this NIR is going to be implemented; that is, what are the techniques and measures that the PMoU countries are going to bring into operation before 1st January 2011. The second is to contribute to improving this NIR. Any complex new convention and procedures are bound to have mistakes, flaws and weak points, therefore the corresponding documents are to be amended by new annexes shortly to be published.
Three-dimensional "atomistic" simulation of discrete random dopant distribution effects in sub-0.1 /spl mu/m MOSFET's

In this paper, discrete random dopant distribution effects in sub-0.1 /spl mu/m MOSFET's were studied using three-dimensional drift-diffusion "atomistic" simulations. Effects due to the random fluctuation of the number of dopants in the MOSFET channel and the microscopic random distribution of dopant atoms in the MOSFET channel were investigated. We found that, in addition to the well-known fluctuation of the threshold voltage, there was an average shift of the threshold voltage to a lower value. The average shift was believed to be attributed to the inhomogeneity of channel potential due to the discreteness of channel dopants, and the logarithmic dependence of subthreshold current. Microscopic dopant distribution also gave rise to asymmetry in drain current upon interchanging the source and the drain. <<ETX>>
Sputter deposition of multilayer thermoelectric films: An approach to the fabrication of two-dimensional quantum wells

The relative efficiency of a thermoelectric material is measured in terms of a dimensionless figure of merit, ZT. Though all known thermoelectric materials are believed to have ZT≤1, recent theoretical results predict that thermoelectric devices fabricated as two‐dimensional quantum wells (2D QWs) or one‐dimensional (1D) quantum wires could have ZT≥3. Multilayers with the dimensions of 2D QWs have been synthesized by alternately sputtering Bi0.9Sb0. 1 and PbTe0.8Se0. 2 onto a moving single‐crystal sapphire substrate from dual magnetrons. These materials have been used to test the thermoelectric quantum‐well concept and gain insight into relevant transport mechanisms. If successful, this research could lead to thermoelectric devices that have efficiencies close to that of an ideal Carnot engine. Ultimately, such devices could be used to replace conventional heat engines and mechanical refrigeration systems.
Corneal biomechanical metrics in thin cornea of normal, keratoconus suspect and keratoconus in Egyptian population

Background To assess and compare corneal hysteresis (CH) and corneal resistance factor (CRF) in normal thin (NT) healthy corneas with central corneal thickness (CCT) 470-500 µm with matched thickness in keratoconus (KC) and keratoconus suspect (KCS) eyes. Methods A total of 66 eyes in three groups were included prospectively: NT, KCS and KC groups based on clinical examination and topography. Corneal hysteresis (CH) and corneal resistance factor (CRF) were measured by the ocular response analyzer. CH and CRF were compared between the three groups and statistically analyzed by variances test. Results The three groups consisted of 32 NT, 19 KCS, and 15 KC. The mean CH measured was 8.55± 1.77, 9.03± 1.119 and 8.06 ± 0.85 mm Hg in NT, KCS and KC eyes, respectively. The mean CRF was 8.39 ± 1.47, 8.27 ± 1.09 and 7.24 ± 1.27 mm Hg in NT, KCS and KC eyes, respectively. Within range of central corneal thickness (470 – 500 µm), only mean CRF was statistically significantly different between the NT and KC (P < 0.05); there was no statistically significant difference between NT and KCS, nor the mean CH between each groups (P > 0.05). Conclusions CRF only can be helpful in differentiating KC from NT eyes; however, it’s not valuable for detecting KCS which is the main concern for refractive surgery. No benefit from CH in differentiating between the study groups. Further investigations & work focusing on more accurate tests for identifying KCS are still needed.
Can the Rail Industries Flatcar Inventory Support Two Major Theater Wars

Abstract : The ability of U.S. forces to change rapidly from a peacetime to a wartime force (to mobilize and deploy) is vitally important to national security. Successful execution of these movements depends, in large part, on the availability of the required transportation resources. Today's Army is heavily dependent on Department of Defense (DoD) and commercial rail car assets to move its wheeled/tracked vehicles from home forts to seaports of embarkation (SPOEs) to meet prescribed mobilization and deployment timelines. The primary research question answered by this paper is "Can U.S. military and commercial flatcar inventories meet DoD mobilization requirements for Army wheeled/tracked vehicles during two near-simultaneous major theater wars (MTWS)? " This paper compares commercial and military flatcar requirements as stated in DoD deployment plans with current/future flatcar inventories to determine whether rail car inventories (both commercial and DoD) are sufficient in number and type to meet a two-MTW scenario. The study shows that today's fleet of commercial and DoD flatcars is sufficient in number and type to support two near-simultaneous MTWs. However, future inventories of commercial, general-purpose flatcars will likely be insufficient due to current rail car production and retirement trends. Several recommendations are presented to ensure future inventories of militarily useful flatcars will be sufficient in number and type to meet DoD mobilization requirements in support of the two near simultaneous MTWs.
University Business Incubators: A Systematic Literature Review from 2000 to
2019

Business incubation initiatives have gained increased attention of researchers, practitioners, and policymakers due to its unique ability to provide a conducive environment that develops and accelerates entrepreneurship. University-based incubation centers have become an essential part of the entrepreneurship support services at campuses to offer critical support and provide various services to newly established start-ups. Recognizing the importance of university incubation centers, researchers are studying various aspects related to university-based business incubators to promote entrepreneurship among university students. In this study, a systematic literature review on university business incubators is conducted on 61 research articles selected after a rigorous process from three databases (ISI-Web of Knowledge, Taylor & Francis, Emerald). Studies were analyzed to answer four main questions related to university business incubators' methodological considerations, proximal and distant outcomes, theoretical lenses, and major research streams. Results revealed that the majority of the research is being done in European countries and the majority of research articles (50%) were published in 2017 to 2019 most having qualitative designs that indicate the importance of campus-based incubation initiatives to promote entrepreneurship. Proximal and distant outcomes revealed various factors at individual, team, firm, institutional, and policy levels. Institutional, network, and resource based-view (RBV) is the main theoretical underpinnings focused on institutional and firm-level studies. This study contributed by analyzing, summarizing, and evaluating UBI’s literature concerning methodological considerations, proximal and distant outcomes, and trend of major research streams.
