Dynamic load balancing for network intrusion detection systems based on distributed architectures (2007)

Increasing traffic and the necessity of stateful analyses impose strong computational requirements on network intrusion detection systems (NIDS), and motivate the need of distributed architectures with multiple sensors. In a context of high traffic with heavy tailed characteristics, static rules for dispatching traffic slices among distributed sensors cause severe imbalance. Hence, the distributed NIDS architecture must be combined with adequate mechanisms for dynamic load redistribution. In this paper, we propose and compare different policies for the activation/deactivation of the dynamic load balancer. In particular, we consider and compare single vs. double threshold schemes, and load representations based on resource measures vs. load aggregation models. Our experimental results show that the best combination of a double threshold scheme with a linear aggregation of resource measures is able to achieve a really satisfactory balance of the sensor loads together with a sensible reduction of the number of load balancer activations.
Relative inhibitory potencies of flavonoids on 12‐lipoxygenase of fish gill (1988)

The relative efficacy of 10 flavonoid compounds and some common antioxidants in inhibiting 12-lipoxygenase of fish gill was determined. Lipoxygenase activity was measured by oxygen consumption with polarography and formation of hydroxy fatty acid using thin layer chromatography with autoradiography. Generally, the inhibition of 12-lipoxygenase by flavonoids was noncompetitive. The lipoxygenase product pattern did not change in the presence of flavonoids. Fisetin (3,3',4',7-tetrahydroxyflavone) and quercetin (3,3',4',5,7-pentahydroxyflavone) were the most potent inhibitors of 12-lipoxygenase, with IC50's of 0.25 and 0.4 microM respectively. These were compared with IC50's values of 5,1000 microM for BHA (t-butylhydroxyanisole) and BHT (t-butylhydroxytoluene) respectively. Possible inhibitory mechanisms and relationships between flavonoid structure and inhibitory potencies are discussed.
Interactive Perspective Cut-away Views for General 3D Scenes (2006)

We present a technique that allows a user to look beyond occluding objects in arbitrary 3D graphics scenes. In order to control this form of virtual x-ray vision, the user interactively cuts holes into the occluding geometry. The user can rapidly define a cutout shape or choose a standard shape and sweep it over the occluding wall segments to reveal what lies behind them. Holes are rendered in the correct 3D perspective as if they were actually cut into the obstructing geometry, including border regions that give the cutout shape physical depth, simulating penetration of a physical wall that possesses some generic thickness.
Mechanisms of Action of Carvacrol on the Food-Borne Pathogen <i>Bacillus cereus</i> (1999)

Carvacrol, a naturally occurring compound mainly present in the essential oil fraction of oregano and thyme, was studied for its effect on bioenergetic parameters of vegetative cells of the food-borne pathogen Bacillus cereus. Incubation for 30 min in the presence of 1 to 3 mM carvacrol reduced the viable cell numbers exponentially. Carvacrol (2 mM) significantly depleted the intracellular ATP pool to values close to 0 within 7 min. No proportional increase of the extracellular ATP pool was observed. Depletion of the internal ATP pool was associated with a change of the membrane potential (Deltapsi). At concentrations of 0.01 mM carvacrol and above, a significant reduction of Deltapsi was observed, leading to full dissipation of Deltapsi at concentrations of 0.15 mM and higher. Finally, an increase of the permeability of the cytoplasmic membrane for protons and potassium ions was observed (at 0.25 and 1 mM carvacrol, respectively). From this study, it could be concluded that carvacrol interacts with the membranes of B. cereus by changing its permeability for cations like H(+) and K(+). The dissipation of ion gradients leads to impairment of essential processes in the cell and finally to cell death.
Fluorescence spectroscopy studies on the action of rare earths with bovine serum albumin in multimolecular system (1995)

In this paper. the interaction of tripositive terbium ions (Tb3+) with bovine serum albumin (BSA) has been investigated in the presence of some alkaline earth metals and citric acid (Cit) by using fluorescence spectroscopy. The results show that Tb-31. BSA and Cit can form ternary complex BSA . Tb-2. Cit(4) in mu =0.1 mol/l NaCl. pH6.3 hexamethylenetetramine buffer. Other tare earths are able to compete for the same binding site in BSA with Tb3+-. The sequence of con,petition is Eu3+>Pr3+>Yb3+>Gd3+>La3+>Ca2+ and Mg2+ cannot replace Tb bound to BSA.
Physicochemical Stability of NOX-E36, a 40mer L-RNA (Spiegelmer) for Therapeutic Applications (2008)

Spiegelmers are structured mirror-image oligonucleotides that are designed to bind and inhibit pharmacologically relevant target molecules. The synthesis and purification of mirror-image oligonucleotides is comparable to the manufacturing of standard oligonucleotides that consist of naturally configured nucleotides. Due to the use of the non-natural L-nucleotides in Spiegelmers, these oligonucleotides show an exceptional biostability. Further, they also display a high physicochemical stability in solution. These properties make them interesting substances for drug development.
Applications of magnetic 'power production' and its assessment. A feasibility study - Final Report (2008)

This final report for the Swiss Federal Office of Energy (SFOE) takes a look at how magnetic power conversion systems could present an alternative to conventional power conversion technologies. Magnetic 'power generators' based on permanent or superconducting magnets are proposed and analysed for numerous heat-source temperatures, magnetic field strengths and frequencies of rotating porous heat exchanger machines. Such machines have been proposed in a patent deposited by the University of Applied Sciences of Western Switzerland (HEIG-VD/IGT/SIT division). A special numerical analysis is looked at that takes advantage of a thermodynamic model which permits the determination of thermodynamic efficiency, exergy efficiency, total mass and total volume of such magnetic power conversion machines. Magneto-caloric materials are discussed and the advantages and disadvantages of such systems are discussed. The report is concluded with an overview of various systems working under different operating conditions. The systems are listed and evaluated as far as their potential for application in the area of magnetic power conversion is concerned.
Designing Direct Subsidies for the Poor : A Water and Sanitation Case Study (2000)

Direct subsidies are an increasingly popular means of making infrastructure services more affordable to the poor. Under the direct subsidy approach, governments pay part of the water bill of poor households that meet certain criteria. This approach was first used in water sector reforms in Chile in the early 1990s and is an alternative to the traditional method in which governments pay subsidies directly to utilities, often allowing the price of water to fall below economic costs indiscriminately. This Note illustrates how simulation techniques can be used to inform the design of direct subsidy schemes, ensuring that they are both cost-effective and accurate in reaching the target population.
FRACTURE TOUGHNESS OF HIGH-DENSITY SINTERED STEELS (2014)

Yield stress, tensile strength and fracture toughness of a PM steel (Fe-4.0Ni-1.5Cu-0.5Mo-0.5C) have been studied as a function of sintered density in the high-level range, from 7.22 to 7.51 g/cm3. The material was processed by different routes combining both cold and warm compaction with single and double pressing-sintering sequences. Fracture toughness was tested by mode I crack opening in a three-point bending test in accordance with the standard procedure ASTM E-399. Validity of fracture toughness tests in these materials is discussed. A quantitative analysis of porosity was correlated with tensile and fracture parameters to assess the influence of pore morphology on mechanical behavior. Microstructural characterization reveals that pores tend to be bigger and more clustered at lower densities. All the mechanical properties increased with a reduction in porosity, being this conjugated performance a remarkable advantage over wrought steels. In spite of using three different lubricants in the processing routes involved, it is found that mechanical properties depend solely on the attained sintered density regardless the route followed to achieve it.

Understanding the earth : a reader in the earth sciences (1971)

During the past decade, research by oceanographic geophysicists which has led to the wide acceptance that continents drift about the face of the earth and to the concept of sea-floor spreading has culminated in an all-embracing theory known as 'plate tectonics.' This theory draws sea-floor spreading, continental drift, crustal structures, and world patterns of seismic and volcanic activity together as aspects of one coherent picture. Not only does it explain geophysical evidence and provide a framework within which geological data accumulated over the past two centuries can be fitted; it has also taken the Earth sciences to the stage where they can explain what has happened in the past and what is happening at the present time, and predict what will happen in the future. In addition, the book covers other currently exciting advances in the Earth sciences such as the accurate dating of rocks by radiometric methods; the Earth's internal composition, magnetic field, heat and internal temperatures; the Chandler Wobble; meteorites; and the Earth-Moon system. Three final chapters illustrate the role of the Earth sciences in society: earthquake prediction and modification, nuclear explosions and earthquakes, and a cautionary yet illuminating account of the Mohole project, which became perhaps the greatest fiasco in the history of science. Although the book is arranged in a sequence the editors feel is a logical one for straightforward reading, each chapter is self-contained and is introduced by a brief explanatory preface.
DC offset suppression in double balance direct conversion receivers (2003)

The double balance mixer scheme in-phase signal input and double-quadrature local oscillator (LO) is suggested for application on IQ direct conversion receivers. The influence of the gain and phase mismatches of splitters is investigated. It is shown that a similar scheme using square-law detectors is promising on optical applications.
Hypersensitivity syndrome caused by amitriptyline administration (2000)

Adverse cutaneous manifestations are among the most common side effects associated with psychotropic drugs. Skin reactions due to amitriptyline (a tricyclic antidepressant agent) include rashes and hypersensitivity reactions (for example, urticaria and photosensitivity) as well as hyperpigmentation. Hypersensitivity syndrome is a specific severe idiosyncratic reaction causing skin, liver, joint, and haematological abnormalities, which usually resolve after the discontinuation of the implicated drug. A case of a 24 year old woman who experienced hypersensitivity syndrome three weeks after the initiation of amitriptyline is reported.
Performance of a path tracing task using stereoscopic and motion based depth cues (2010)

Stereoscopic displays have a number of properties that could be advantageous in the field of medical diagnosis. The aim of the current study is to get a better understanding of the relative importance of motion based depth cues (object motion, movement parallax) and stereoscopic disparity on the performance of a path tracing task, representative of angiographic visualizations. To date, these cues have not frequently been combined in a single study that would allow a direct comparison of their effects. In this paper, we report on an experiment where we measured the effectiveness of motion-based cues and stereoscopic disparity in terms of completion time, number of errors, perceived workload and perceived discomfort. Results revealed that both object motion and movement parallax enhanced performance in terms of number of correct answers. However, object motion was superior to motion parallax on self-report of mental workload and visual comfort. Stereoscopic disparity significantly decreased completion times when combined with object motion or movement parallax. On accuracy, no effect of stereo was found.

The United States Air Force Expeditionary Center: Airpower from the Ground Up (2010)

Abstract : The American Expeditionary Force was created in 1917 as the first unit capable of significant over-the-horizon global power projection of US forces. Ninety years later, the US Air Force Expeditionary Center (USAF EC) received its commission as a training center of excellence for expeditionary operations. Between 1917 and today, everything--yet nothing--has changed in the world of expeditionary operations. That is, although the time required to project global power over the horizon has shrunk from months to hours, the enabling engine of that force projection remains the same: military and civilian professionals suitably trained and equipped to support the endeavor. The Air Force's ability to project power in air, space, and cyberspace has advanced significantly, but at the core remains the requirement to build the foundation of that airpower projection from the ground up. On the bookshelf of the Air Force's advanced training capabilities, the USAF EC serves as the bookend complement to the US Air Force Warfare Center (USAF WC), the former focusing on airpower from the ground and the latter emphasizing airpower from above. Key to both bookends of this bookshelf is the ability to evolve with the speed of change and thus remain relevant to Airmen charged with over-the-horizon global power projection. The USAF EC's relevance lies in providing advanced training for expeditionary Airmen to support the joint fight and to develop the tactics, techniques, and procedures (TTP) that today's expeditionary combat support (ECS) mission needs to project airpower from the flight line to the front line, from the ground up. This article offers insight into the design of the USAF EC, discusses how this design contributes to enabling the effects of its two schools, and shows how those effects are integrated across the spectrum of the ECS mission in building airpower from the ground up.
Magnetic field sensing scheme using CoFeB∕MgO∕CoFeB tunneling junction with superparamagnetic CoFeB layer (2006)

The authors investigated the tunneling magnetoresistance (TMR) of CoFeB∕MgO∕CoFeB tunnel junctions by varying the thickness (tCoFeB) of the top CoFeB layer. Linear and hysteresis-free switching was observed in junctions with tCoFeB⩽10Å, while normal tunneling behavior occurred for tCoFeB&gt;10Å. The field sensitivity and the sensing field range were found to be controlled by varying the thickness of the sensing layer. This finding means that the magnetic tunneling junction (MTJ) provides a scheme for magnetic field sensing, which has a simple sensor design and low power consumption. The magnetic properties of the sensing layer with tCoFeB⩽10Å were found to show the characteristics of superparamagnetism. Although the detailed mechanism of TMR in MTJs with a superparamagnetic layer is not fully understood at present, this phenomenon is observed repeatedly. Therefore, this sensing scheme would be an alternative method for overcoming the problems in magnetic sensors with a crossed magnetization pattern.
Study of a thermal aerosol oil burner. Final report Sep 76--May 77 (1977)

The report gives results of a study of a thermal aerosol oil burner, aimed at counteracting the poor atomization and excess burner capacity that are known to reduce seasonal efficiency and contribute to excess emissions in residential oil burners. Generation of a thermal aerosol of the fuel was shown to improve combustion in terms of: (1) increased quantity and volume of fuel droplets 1 micrometer and smaller; (2) permitted firing rate reduction in standard nozzles of 50 to 70%; (3) when combined with swirl (swirl parameter = 4.5), gave increased combustion efficiency by permitting operation at 2% flue oxygen with nonluminous flame, zero Bacharach smoke No., no hydrocarbons, and no detectable CO; (4) reduced NOx formation in most cases; (5) reduced emissions during burner start-up; and (6) permitted modulation of firing rate without affecting combustion adversely.
Impact of Congestive Heart Failure Treatment on Peripheral Microvascular Tissue Oxygenation (2011)

The authors evaluated peripheral tissue oxygenation during treatment of acutely decompensated congestive heart failure (CHF) to determine whether differences exist between patients who experienced adverse outcomes (AO), defined as death or readmission within 6 months, and patients who did not (non-AO). This prospective, observational study measured differential absorption spectroscopy-derived tissue hemoglobin oxygenation (S(t) O(2) ) in CHF patients from presentation through hospital discharge to determine whether differences between the AO and non-AO groups exist. Of 52 patients, 6 died and 27 were readmitted. In the non-AO group, S(t) O(2) increased from admission to discharge by 5.2% ( P<.01; 95% confidence interval, 1.7%-8.7%). No S(t) O(2) change occurred in the AO group (2.3%; P=.42; 95% CI, -2.2%-6.8%). Tissue oxygenation increased during inpatient treatment in CHF patients without future adverse outcomes, but was unchanged for those who later died or were readmitted. Lack of improvement may be associated with higher rates of death and readmission.
Phase Retrieval And Diversity In Adaptive Optics (1982)

Wavefront sensing by phase retrieval implies extraction of the Fourier transform of a complex signal based on observation of the modulus of the signal. Only the image intensity from a system's focal plane array is required to estimate the phase aberrations. These estimates are used to derive control signals to align (or to maintain alignment of) the optical system. The concept can be used in both a predetection and postdetection mode. In the former, the control system labors to keep the optics in a diffraction-limited mode all the time. In the latter, the control system induces a phase or wavelength diversity that allows successive images to be restored to nearly diffraction-limited quality by postprocessing of the image. This second mode is particularly interesting because it will reduce the design effort for both the optical system and the control system. How the phase or wavelength diversity is achieved is not clear at this time. If the method has utility, it provides an interesting challenge to designers of optical devices. In this paper we describe the mathematics of the technique and show some computer simulations which involve both point sources and extended objects.
Automated solar module assembly line. Final report (1980)

The solar module assembly machine which Kulicke and Soffa delivered under this contract is a cell tabbing and stringing machine, flexible in design, and capable of handling a variety of cells and assembling strings up to 4 feet long which then can be placed into a module array up to 2 feet by 4 feet in a series or parallel arrangement, and in a straight or interdigitated array format. The machine cycle is 5 seconds per solar cell. This machine is primarily adapted to 3 inch diameter round cells with two tabs between cells. Pulsed heat is used as the bond technique for solar cell interconnects. The solar module assembly machine unloads solar cells from a cassette, automatically orients them, applies flux and solders interconnect ribbons onto the cells. It then inverts the tabbed cells, connects them into cell strings, and delivers them into a module array format using a track mounted vacuum lance, from which they are taken to test and cleaning benches prior to final encapsulation into finished solar modules. Throughout the machine the solar cell is handled very carefully, and any contact with the collector side of the cell is avoided or minimized. A lamp simulator has been used to test bonded solar cells to determine if the bonding operation had any degrading effect on the cell. I-V profile curves taken of these sample cells, before and after the bonding operation indicate no apparent effect on the electrical characteristics of the solar cell by the bonding operation.
