Research on immune storage anomaly detection via user access behavior

If an intruder uses a stolen account, the authentication sub-system will regard the intruder as a legitimate user. In order to filter out such illegal users, the storage system should be capable of the user activity diagnosis. This paper presents a novel anomaly detection scheme to monitor the user access activities using the artificial immune technique. When an access request violates the access control rule, it is regarded as Non-self, so as to provide some early warning tips to the storage security sub-system. Compared with the NIDS, the proposed scheme targets the anomaly detection at storage level and focuses on the read/write data requests. In the prophase of simulation, a set of optimal parameters of algorithm are fitted according to the mean convergence speed and detection efficiency. The simulation shows the proposed scheme can reach rather high detection rate and low false alarm rate, further validating its feasibility. Thus the storage anomaly detection would strengthen the storage early warning and improve the storage security.
Boost-half-bridge edge resonant soft switching PWM high-frequency inverter for consumer induction heating appliances

A novel soft-switching PWM utility frequency AC to high-frequency AC power conversion circuit, incorporating boost-half-bridge inverter topology, which is more suitable and acceptable for cost effective consumer induction heating applications, is presented. The operating principle and the operation modes are described using equivalent circuits with the operating voltage and current waveforms. The operating performances are illustrated and evaluated, including the power regulation and power conversion efficiency against duty cycle characteristics based on the power dissipation as compared with those of the previously developed high-frequency inverter. The practical effectiveness of the power converter is substantially proved, based on experimental results from a practical design example.
Fatigue and Serviceability Limit State Model Basis for Assessment of Offshore Wind Energy Converters.

This paper develops the models for the structural performance of the loading and probabilistic characterization for the fatigue and the serviceability limit states for the support structure of offshore wind energy converters. These models and a sensitivity study are part of a risk based assessment and monitoring framework and will be applied for establishing the "as designed and constructed" reliability as prior information for the assessment and the design of monitoring systems. The constitutive physical equations are introduced in combination with the fatigue and serviceability limit state requirements as the starting point for the development of the structural performance and loading models. With these models introduced in detail, several modeling aspects for both limit states are analyzed. This includes analyses of the influence on the hot spot stresses by applying a contact formulation for the pile guide brace connection and the application of a finite element formulation using solid elements. Further, the comparison of the natural frequencies of a discrete rotor model with a continuous rotor model is documented. To account for uncertainties associated with the structural and loading models, a probabilistic model is derived on the basis of literature review and measurement data from a prototype Multibrid M5000 support structure. The sensitivity study is based on the calculation of a nonlinear coefficient of correlation in conjunction with predetermined designs of experiments. This is conducted by a systematic analysis of the influence of the random variables on limit state responses and hence on the structural reliability. Integrating the analyses and sensitivity studies of the fatigue and serviceability limit state models developed in this paper as well as the ultimate limit state models in Thons et al. ("Ultimate Limit State Model Basis for Assessment of Offshore Wind Energy Converters," ASME J. Offshore Mech. Arct. Eng.), the model basis for the assessment is completed. The process of establishing and analyzing such a model basis contributes to a detailed understanding of the deterministic and probabilistic characteristics of the structure and provides valuable insights in regard to the significance of available data.
Guided Wave Beamsteering using MFC Phased Arrays for Structural Health Monitoring: Analysis and Experiment

Phased array beamsteering is an effective tool for damage detection and assessment method in a guided wave structural health monitoring system. Monolithic piezoceramic (PZT) actuators have been widely utilized for beamsteering by assuming omnidirectional point sources for each actuator. However, this assumption can lead to erroneous results for a phased array of actuators with anisotropic actuation, such as macro-fiber composites (MFC). The MFC actuators are investigated in this research for beamsteering considering the main lobe width, main lobe magnitude, and side lobe levels and compared to equivalently sized PZT actuators. Analytical models of the MFC and PZT actuators attached to an isotropic plate structure are presented and the genetic algorithm is used to determine the optimal timing sequences of the phased array elements for beamforming enhancement. The analysis results show that the MFC phased arrays have reduced the main lobe width and side lobe levels compared to the PZT phased arrays for a range of beamsteering angles. The area ratios of the MFC arrays are also found to be greater than the PZT arrays for these beamsteering angles. Experiments using the PZT and MFC phased arrays on an aluminum plate are performed and compared to the analysis results. The experiment results agree with the analysis results and demonstrate improved beamsteering of the MFC phased arrays for specific applications.
Sildenafil Citrate for Women

Sildenafil citrate (SC) is a medicinal drug used to treat male erectile dysfunction and pulmonary hypertension. Sildenafil is a selective and potent competitive inhibitor of the cyclic guanosine monophosphate (cGMP) -specific phosphodiesterase-type 5 (PDE-5) enzymes, which, by preventing the breakdown of cGMP, potentiate the action of NO in tissues that contain PDE-5. Thus, increasing vasodilatation and potentiating the effects of nitrous oxide (NO) on the vascular smooth muscle [1-2]. SC increases uterine blood flow and potentiates estrogen-induced vasodilatation [3]. Sildenafil citrate is metabolized is in the liver by cytochrome P450, the metabolites are: N-desmethylsildenafil (about 50% potency for PDE5). The biological half-life is from 3 to 4 hours, it is excreted in feces and in urine [4].
X-RAY CT Reconstruction by using Spatially Non Homogeneous ICD Optimization

Recent applications of conventional iterative coordinate descent (ICD) algorithms to multislice helical CT reconstructions have shown that conventional ICD can greatly improve image quality by increasing resolution as well as reducing noise and some artifacts. However, high computational cost and long reconstruction times remain as a barrier to the use of conventional algorithm in the practical applications. Among the various iterative methods that have been studied for conventional, ICD has been found to have relatively low overall computational requirements due to its fast convergence. This paper presents a fast model-based iterative reconstruction algorithm using spatially nonhomogeneous ICD (NH-ICD) optimization. The NH-ICD algorithm speeds up convergence by focusing computation where it is most needed. The NH-ICD algorithm has a mechanism that adaptively selects voxels for update. First, a voxel selection criterion VSC determines the voxels in greatest need of update. Then a voxel selection algorithm VSA selects the order of successive voxel updates based upon the need for repeated updates of some locations, while retaining characteristics for global convergence. In order to speed up each voxel update, we also propose a fast 3-D optimization algorithm that uses a quadratic substitute function to upper bound the local 3-D objective function, so that a closed form solution can be obtained rather than using a computationally expensive line search algorithm. The experimental results show that the proposed method accelerates the reconstructions by roughly a factor of three on average for typical 3-D multislice geometries.
Challenges in the development of advanced Li-ion batteries: a review

Li-ion battery technology has become very important in recent years as these batteries show great promise as power sources that can lead us to the electric vehicle (EV) revolution. The development of new materials for Li-ion batteries is the focus of research in prominent groups in the field of materials science throughout the world. Li-ion batteries can be considered to be the most impressive success story of modern electrochemistry in the last two decades. They power most of today's portable devices, and seem to overcome the psychological barriers against the use of such high energy density devices on a larger scale for more demanding applications, such as EV. Since this field is advancing rapidly and attracting an increasing number of researchers, it is important to provide current and timely updates of this constantly changing technology. In this review, we describe the key aspects of Li-ion batteries: the basic science behind their operation, the most relevant components, anodes, cathodes, electrolyte solutions, as well as important future directions for R&D of advanced Li-ion batteries for demanding use, such as EV and load-leveling applications.

Between Silk and Cyanide: A Codemaker's War, 1941-1945

In 1942, with a black-market chicken tucked under his arm by his mother, Leo Marks left his father's famous bookshop, 84 Charing Cross Road, and went off to fight the war. He was twenty-two. Soon recognized as a cryptographer of genius, he became head of communications at the Special Operations Executive (SOE), where he revolutionized the codemaking techniques of the Allies and trained some of the most famous agents dropped into occupied Europe. As a top codemaker, Marks had a unique perspective on one of the most fascinating and, until now, little-known aspects of the Second World War. This stunning memoir, often funny, always gripping and acutely sensitive to the human cost of each operation, provides a unique inside picture of the extraordinary SOE organization at work and reveals for the first time many unknown truths about the conduct of the war. SOE was created in July 1940 with a mandate from Winston Churchill to "set Europe ablaze. " Its main function was to infiltrate agents into enemy-occupied territory to perform acts of sabotage and form secret armies in preparation for D-Day. Marks's ingenious codemaking innovation was to devise and implement a system of random numeric codes printed on silk. Camouflaged as handkerchiefs, underwear, or coat linings, these codes could be destroyed message by message, and therefore could not possibly be remembered by the agents, even under torture. "Between Silk and Cyanide" chronicles Marks's obsessive quest to improve the security of agents' codes and how this crusade led to his involvement in some of the war's most dramatic and secret operations. Among the astonishing revelations is his account of the code war between SOE and theGermans in Holland. He also reveals for the first time how SOE fooled the Germans into thinking that a secret army was operating in the Fatherland itself, and how and why he broke the code that General de Gaulle insisted be available only to the Free French. By the end of this incredible tale, truly one of the last great World War II memoirs, it is clear why General Eisenhower credited the SOE, particularly its communications department, with shortening the war by three months. From the difficulties of safeguarding the messages that led to the destruction of the atomic weapons plant at Rjukan in Norway to the surveillance of Hitler's long-range missile base at Peenemunde to the true extent of Nazi infiltration of Allied agents, "Between Silk and Cyanide" sheds light on one of the least-known but most dramatic aspects of the war. Writing with the narrative flair and vivid characterization of his famous screenplays, Marks gives free rein to his keen sense of the absurd and wry wit without ever losing touch with the very human side of the story. His close relationship with "the White Rabbit" and Violette Szabo -- two of the greatest British agents of the war -- and his accounts of the many others he dealt with result in a thrilling and poignant memoir that celebrates individual courage and endeavor, without losing sight of the human cost and horror of war.
Renal Sensory Nerves Increase Sympathetic Nerve Activity and Blood Pressurein 2-Kidney 1-Clip Hypertensive Mice.

Renal denervation lowers arterial blood pressure (ABP) in multiple clinical trials and some experimental models of hypertension. These antihypertensive effects have been attributed to the removal of renal afferent nerves. The purpose of the present study was to define the function, anatomy, and contribution of mouse renal sensory neurons to a renal-nerve dependent model of hypertension. First, electrical stimulation of mouse renal afferent nerves produced frequency-dependent increases in ABP that were eliminated by ganglionic blockade. Stimulus-triggered averaging revealed renal afferent stimulation significantly increased splanchnic, renal, and lumbar SNA. Second, kidney injection of wheat germ agglutinin into male C57Bl6 mice (12-14 weeks, Jackson Laboratories) produced ipsilateral labeling in the T11-L2 dorsal root ganglia. Next, 2K1C hypertension was produced in male C57Bl6 mice (12-14 weeks, Jackson Laboratories) by placement of a 0.5mm length of PTFE tubing around the left renal artery. 2K1C mice displayed an elevated ABP measured via telemetry and greater fall in mean ABP to ganglionic blockade at day 14 or 21 vs day 0. Renal afferent discharge was significantly higher in 2K1C-clipped versus 2K1C-unclipped or sham kidneys. In addition, 2K1C-clipped versus 2K1C-unclipped or sham kidneys had lower renal mass and higher mRNA levels of several pro-inflammatory cytokines. Finally, both ipsilateral renal denervation (10% phenol) or selective denervation of renal afferent nerves (periaxonal application of 33 mM capsaicin) at time of clipping resulted in lower ABP of 2K1C mice at Days 14 or 21. These findings suggest mouse renal sensory neurons are activated to increase SNA and ABP in 2K1C hypertension.
Design of LED spherical lamps for uniform far-field illumination

Light-Emitting Diodes (LEDs) have matured to the point that they can be considered to replace the inefficient and short life incandescent lamps in many lighting applications. Though modern high power LEDs produce up 120 lumens per device, several individual LEDs must be mounted on panels to obtain practical powers. In this paper we analyze, by considering each single LED as an imperfect Lambertian emitter, the first order design of a lamp consisting of several LEDs assembled upon a spherical surface to uniformly illuminate far targets. Practical formulas are derived for the optimum LED-to-LED spacing, i.e., the optimum packaging density, of ring array configurations to achieve uniform far-field irradiance.

Detection and monitoring of hidden fatigue crack growth using a built-in piezoelectric sensor/actuator network: I. Diagnostics

A piezoelectric based built-in diagnostic technique has been developed for monitoring fatigue crack growth in metallic structures. The technique uses diagnostic signals, generated from nearby piezoelectric actuators built into the structures, to detect crack growth. It consists of three major components: diagnostic signal generation, signal processing and damage interpretation. In diagnostic signal generation, appropriate ultrasonic guided Lamb waves were selected for actuators to maximize receiving sensor measurements. In signal processing, methods were developed to select an individual mode for damage detection and maximize signal to noise ratio in recorded sensor signals. Finally, in damage interpretation, a physics based damage index was developed relating sensor measurements to crack growth size. Fatigue tests were performed on laboratory coupons with a notch to verify the proposed technique. The damage index measured from built-in piezoceramics on the coupons showed a good correlation with the actual fatigue crack growth obtained from visual inspection. Furthermore, parametric studies were also performed to characterize the sensitivity of sensor/actuator location for the proposed technique.
Measuring Systemwide Impacts of New Aircraft on the Environment

Many efforts to mitigate the environmental impact of aviation, like NASA’s Subsonic Fixed Wing Project, place high importance on reducing fuel burn, nitrogen oxide (NOX) emissions, and noise of future aircraft. However, the environmental and economic impact of a new aircraft is not solely a function of the aircraft’s performance but also of how airlines use new aircraft along with other existing aircraft to satisfy the passenger demand for air transportation. In this work, an optimization problem finds the optimal allocation of existing and future aircraft to routes representing commercial air transportation within or to/from the United States to measure various fleet-level metrics. Examining fleet-level environmental metrics helps assess how aircraft meeting NASA’s Subsonic Fixed Wing Project goals could impact fleet-level environmental goals established by the International Air Transport Association. The goal set forth by the International Air Transport Association examined in this paper is to reduce to.
Existence of solutions of bilevel strong vector equilibrium problems and their applications

In this paper, a bilevel strong vector equilibrium problem is introduced and investigated by using the Fan’s lemma. Two approaches for finding the solutions of this problem are considered. The applications provide sufficient conditions for the existence of the solutions of a Pareto vector optimization over set constraints and the existence of strong vector saddle points for a generalized Nash two-person noncooperative games where the payoff function is vector-valued.
Applying Systems Modeling Language in an Aviation Maintenance System

The aviation system has experienced an increasing demand over the last decade since it is considered one of the optimal means of transportation. As a result of this increasing demand, aviation organizations have been forced to focus on passenger safety by keeping aircraft airworthy at all times and by investing in the maintenance sector. Recent literature shows that the maintenance sector is still using outdated technology to maintain documentation of an aircraft's maintenance system. This article proposes the use of model-based system engineering (MBSE) as an approach to document aircraft maintenance systems. Systems modeling language (SysML) provides the maintenance system with a more systematic application that would automatically update maintenance records and provide stakeholders with more precise documentation. SysML is expressed through the use of structural and behavioral diagrams for the EA-6B aircraft. This article also provides a look into the use of SysML in the modeling of complex system architecture and the interaction between various systems. The integration of reliability studies and SysML is showcased through a case study. A failure mode and effect analysis is performed to show the usability of SysML in conducting reliability analysis. This article serves as a foundation for practitioners who aim to use MBSE methodology to solve the current setbacks existing in the maintenance aviation sector.
