Inertial s-iteration forward-backward algorithm for a family of nonexpansive operators with applications to image restoration problems

Image restoration is an important branch of image processing which has been studied extensively while there are several methods to solve this problem by many authors with the challenges of computational speed and accuracy of algorithms. In this paper, we present two methods, called ? Inertial S-iteration forward-backward algorithm (ISFBA)? and ? A fast iterative shrinkage-thresholding algorithm-Siteration (FISTA-S)? , for finding an approximate solution of least absolute shrinkage and selection operator problem by using a special technique in fixed point theory and prove weak convergence of the proposed methods under some suitable conditions. Moreover, we apply our main results to solve image restoration problems. It is shown by some numerical examples that our algorithms have a good behavior compared with forward-backward algorithm (FBA), a new accelerated proximal gradient algorithm (nAGA) and a fast iterative shrinkage-thresholding algorithm (FISTA).

Comprehensive review of high power factor ac-dc boost converters for PFC applications

High power factor rectifiers have been consolidated as an effective solution to improve power quality indices in terms of input power factor correction, reduction in the total harmonic distortion of the input current and also regulated dc voltages. Within this context, this subject has motivated the introduction of numerous converter topologies based on classic dc-dc structures associated with novel control techniques, thus leading to the manufacturing of dedicated integrated circuits that allow high input power factor by adding a front-end stage to switch-mode converters. In particular, boost converters in continuous current mode (CCM) are widely employed since they allow obtaining minimised electromagnetic interference levels. This work is concerned with a literature review involving relevant ac-dc single-phase boost-based topologies with high input power factor. The evolution of aspects regarding the conventional boost converter is shown in terms of improved characteristics inherent to other ac-dc boost converters. Additionally, the work intends to be a fast and concise reference to single-phase ac-dc boost converters operating in CCM for engineers, researchers and experts in the field of power electronics by properly analysing and comparing the aforementioned rectifiers.
Site Response Analysis for a Site with the Dipping Bedrock and Liquefiable Layers Using FLAC 3D

To get the precise input motion for seismic analysis of important structures located in liquefiable soil layers, this study demonstrates site response analysis using FLAC 3D [. Based on the previous earthquake diaster experiences and regulatory requirements for nuclear power plants (NPP), the seismic wave propagation in the site having dipping bedrock surface was modeled, also the excess pore water pressure during excitation process was added into the soil elements. The free-field site response model is used to generate the response spectra at different ground surface locations, and to predict the influence range of soil liquefaction. The analysis results show that soil liquefaction could reduce site amplification effect, and might have different degree of impact depending on natural frequency and soil pressure resistance of structures. The 3D model also can capture the soil unceratinties and reflect the real topographic effect in one computer run, so the current multiple one-dimensional equivalent linear analysis process could be improved. Therefore, the FLAC 3D model can fulfill nuclear regulatory requirement, and provide suitable ground-motion prediction for liquefiable soil sites and complex bedrock surface sites for the need of seismic evaluations of existing NPPs after Fukushima Dai-ichi Tragedy.

Experimental and simulation study of the interaction characteristics of nano‐MgO and smoke in the fire of a ship engine room

The engine room of ships with poor ventilation has high concentrations of accumulated smoke during the fires. In some ways, the existing forced ventilation and water mist fire extinguishing can aggravate the occurrence of back‐burning and flame strengthening. In this article, a novel way to control smoke is proposed. Based on nano‐MgO particles, the adsorption mechanism of MgO at different temperatures (300–500 K) was simulated and analyzed using the Monte Carlo method. And the macroscopic adsorption effects of smoke at different angles (30°, 80°, and 110°) of nano‐MgO vertical spray were studied in a closed confined space of 1.5 × 1.5 × 1 m3, where the diesel oil was used as a fire source. The results show that the nano‐MgO have a good dissipation effect on the fire smoke through the analysis of the temperature, smoke concentration and adsorption amount in the confined space, which can effectively reduce the smoke concentration and improve the visibility in the space. The adsorption effect of nano‐MgO is the best when the spray angle is 30°, the adsorption effect of nano‐MgO is the largest when the pressure is 300 KPa and the temperature is 300 K. Besides, the adsorption of nano‐MgO and carbon smoke particles changed from single‐layer to multilayer adsorption in the process of interaction. The research results provide a theoretical basis for the application of nano‐MgO particles in smoke control of the fire in the ship engine room.
Journal of Homeland Security and Emergency Management The Private Sector and the Role of Risk and Responsibility in Securing the Nation ' s Infrastructure

Society faces many common challenges that the corporate sector can play a large role to help address. Security against terrorism is one such challenge and is an important pre-condition to sustainable development. Moreover, since terrorism often operates outside of the jurisdiction of state authorities, it is becoming clear that governments cannot address this issue alone. In the United States, for example, there is a large portion of the nation’s infrastructure that owned by the private sector. Using data obtained from 158 survey responses from security professionals in the public and private sector, our structural equation model determined that while prior field surveys indicate that there are many factors that influence the size of security spending (including a sense of social responsibility and attitude toward risk), the most important factor is the cost-benefit analysis that companies themselves undertake. These results may apply to many situations, such as global warming, piracy and pollution control, in which cooperation from the private sector is needed to address threats whose risk is difficult to assess.
Dynamic Soil-Pile Interaction for large diameter monopile foundations

Monopile foundations have been used in a large extent to support offshore wind turbines (OWT), being considered as a reliable and cost effective design solution. The accurate estimation of their dynamic response characteristics is essential, since the design of support structures for OWTs has been so far driven by their dynamic performance. The excitation frequencies are imposed by the rotation of the rotor, hence they are lumped close to the rotation frequency of the rotor (1P) and the lower blade multiples (2P, 3P). The prevailing design concepts originate from an ‘avoidance of resonance’ rule and are usually reported in double terms of the stiffness of the OWT and the foundation, i.e. soft –soft, soft – stiff, and stiff – stiff design approaches. In the first case the eigenfrequency of the system is reduced to excessively low values, where the cost reduction is considerable but wave fatigue may be problematic. In the third case except from the cost increase, the wind induced fatigue is an additional issue to be dealt with. The second concept is the one prevailing in current design practice and it actually sets the natural frequency of vibration of the OWT inside the narrow margin left between two restrictive frequency areas. Moreover the design of monopile foundations when subjected to combined lateral and moment loading (the latter arising from the eccentricity of the applied wind pressure) usually dictates a large diameter steel pile with small slenderness ratio. Hence, aim of the study is to analyse the dynamic interaction of the soil and a single pile embedded in it by accounting for the geometric and stiffness properties of the pile. In doing so, a semi – analytical approach is adopted based on the fundamental solution of horizontal pile vibration by Novak and Nogami (1977). The dynamic impedance functions of the monopile foundation are obtained for varying soil conditions and it is shown that the first eigenfrequency of the soil layer controls the reduction of the stiffness and the increase of the radiation damping induced by the vibration of the monopile. Higher eigenfrequencies of the soil layer do not affect the soil – pile interaction. The decrease of the eigefrequency of the OWT depends on the aforementioned variation of the dynamic stiffness and the slenderness ratio of the monopile.
Virtualisation and automation of curved shell plates’ manufacturing plan design process for knowledge elicitation

This paper seeks to propose a brand new system for tacit knowledge elicitation in curved shell plates’ manufacturing process. By virtualising the manufacturing process and automatically suggesting manufacturing plans, the system would allow the knowledge-interrelated information more specific and understandable. Five areas are studied: 1) the extraction of a curved shell plate’s real shape from the point cloud measured by laser scanner; 2) the virtualisation of a curved shell plate’s wooden template; 3) the automatic suggestion of the manufacturing plan; 4) the virtualisation of the manufacturing environment; 5) the knowledge elicitation using ripple-down-rules based on the virtualised manufacturing environment and the evaluation result of the system’s suggested manufacturing plan. The system which integrates the proposed approaches above is evaluated by conducting a series of experiments in the shipyard. The tacit knowledge existent in the curved shell plate’s different situations during the manufacturing process are effectively elicited and represented.
Low-Energy Defibrillation Using Resonant Drift Pacing

This thesis explores the feasibility of and seeks to further develop a method of low-energy defibrillation through mathematical modelling and computational experiments. Normally, the contraction of heart muscle is synchronized by a wave of electric excitation which propagates in an orderly fashion through the heart. If propagation of this wave is temporarily blocked it may form a re-entrant circuit. This re-entrant wave overrides the normal heart rhythm causing rapid and uncoordinated contractions which disrupts the heart’s function of pumping blood. It has previously been suggested that delivery of properly timed multiple weak shocks can be used for low-energy defibrillation. If the shocks are applied via a feedback protocol, the re-entrant circuits move until they are terminated at an inexcitable piece of tissue. This is the meaning of the term resonant drift pacing. Resonant drift pacing works on simple mathematical models but, until now, it has not been tested on the most detailed models of cardiac tissue. We assess resonant drift pacing as a method for low-energy defibrillation through numerical simulations of both bidomain and monodomain descriptions of cardiac tissue. We use rectangular geometry as well as anatomically realistic geometry of rabbit ventricles. Termination of re-entry is achieved with high probability at a fraction of the conventional defibrillation shock strength. To explain reasons when resonant drift pacing fail, we further develop the existing theory of resonant drift by extending it into three dimensions. This new theory, and the simulations, reveal reasons when resonant drift pacing has not been successful and we suggest modifications to overcome the difficulties.
A low-cost three-phase zero-current-transition inverter with three auxiliary switches

Most existing three-phase soft-switching inverters with less than six auxiliary switches have fundamental drawbacks in performance. Those with six auxiliary switches have potentially good performance, but with penalties of high cost and large space. This paper proposes a new zero-current-transition (ZCT) inverter topology that reduces the number of auxiliary switches from six to three, without increasing the device power rating or requiring any additional components, for electric vehicle propulsion. With considerable reduction in cost and size, the performance of existing ZCT inverters remains as desired. At main switches and auxiliary switches are turned off under zero-current conditions, and main switches are turned on under a near zero-current condition. Meanwhile, the ZCT implementation does not modify normal space vector modulation (SVM) schemes. A 10 kW prototype has been built and tested to verify the fundamental principle and simulation results.
Mean platelet volume-to-platelet count ratio after elective cardiac surgical procedures is superior in reflecting platelets metabolic hyperactivity compared to other routine morphological platelet indices: A preliminary report

Background Excessive metabolic excitation of platelets after cardiac procedures may be related to some adverse events but assessment of their metabolic activity is not routine. The purpose of this study was to evaluate which of the basic platelet morphological parameters best reflects their metabolic status. Methods The blood samples of 22 cardiac surgical patients (mean age of 62.3 ± 10.3 years) were taken before surgery (BS), and 1, 24 and 48 hours after the operation. Correlations between morphological platelet parameters (platelet count [PLT], mean platelet volume [MPV], platelet distribution width [PDW] and MPV/PLT) and their metabolic activity (total concentration of malondialdehyde [MDA] and MDA/PLT) were estimated. Results Significant decline in PLT after operation (from 223 ± 44 × 1012/L to 166 ± 57 × 1012/L) was accompanied by marked increase in MPV (from 8.4 ± 0.9 fL to 9.1 ± 1.2 fL) and no change of PDW. Consequently, MPV/PLT index increased significantly after procedures from (median with IQR) 0.038 (0.030–0.043) to 0.053 (0.043–0.078). Simultaneously, a significant increase in total platelet MDA content and MDA/PLT was noted reaching peak levels soon after operation. The strongest correlation was observed between MPV/PLT and MDA/PLT (r = 0.56; p < 0.001), although the others were also found to be significant (MDA/PLT vs. MPV; r = 0.35; MDA/PLT vs. PDW; r = 0.34). Conclusions Among basic morphological parameters and indices, the MPV-to-PLT ratio reflects the best metabolic status of platelets in cardiac surgical patients.
Development of a Capacitive Displacement Sensor Based Portable Instrument with Digital Display for Measuring Weld Stagger Joint

In order to ensure the operating security of pressure containers, the P. R. China make a corresponding standard of producing, checking and accepting pressure containers, in which the weld stagger joint is an importance parameter to be measured. Because the zero scale is fixed, the existing mechanical stagger joint measuring scale has scoring error of scale, zero error, visual error and cumulative error, it is not convenient to read and easy to get wrong data, resulting in misjudgment and other defects. The existing capacitive displacement sensor based instrument with digital display for measuring welded joint angularity and stagger is the parameter detection after the weld completed, it cannot be used for detecting welded joint stagger joint before welding, so it is not convenient to adjust the weld and control the welding quality. To make up for the lack of existing measurement tools, we developed a capacitive displacement sensor based portable instrument with digital display for measuring weld stagger joint. This paper introduces its structures and principle. Through error analysis, calculation and experimental testing, the integrated error of the instrument is less than 0.03 mm, the measuring accuracy can meet the requirements prescribed by the GB150-1998 standard.
Improvement of the efficiency of 35 to 220 kV lines

It is good practice to limit the ratio of transmitted power to surge impedance loading (SIL, or natural capacity), S/P/sub n/, to <or=1, with the aim of reducing voltage drop and power losses. The use of flat phases and reduced phase spacings enable the ratio S/P/sub n/ to be confined to <or=1, which considerably enhances the economic efficiency and quality of power transmission, enables the transmission distance to be increased and the operational lifetime of existing systems to be extended. Conductor bundling and ultimate reduction of phase spacings, down to distances determined by the requirements of reliable operation and lightning surges, allow an increase in the transmission capacity of 35 to 220 kV lines virtually in proportion to the number of subconductors per phase, i.e., by a factor of 3, 4 or more as compared to traditional lines. An increased transmission capacity of compact lines is attained with relatively small phase sizes.
Analysis of Transmission Towers with Different Configurations

Transmission line towers constitute about 28 to 42 percent of the cost of the transmission line. The increasing demand for electrical energy can be met more economically by developing different light-weight configurations of transmission line towers. In this report, an attempt has been made to make the transmission line more cost effective by changing the geometry (shape) and behavior (type) of transmission line structure. This objective is met by choosing a 220 kV single circuit transmission line carrying square base self-supporting towers. With a view to optimize the existing geometry, one of these suspension towers is replaced by a triangular base self-supporting tower. Then, the structural behavior of existing tower is looked upon by developing a square base guyed mast. Using STAAD, analysis of each of these three towers has been carried out as a three-dimensional structure. Then, the tower members are designed as angle sections. For optimizing any member section, the entire wind load computations have to be repeated, simultaneously for the analysis and design. Then, all these three towers are compared and analyzed.
Frequency agility and fusion for tracking targets in the presence of multipath propagation

The problems induced by over-the-water multipath effects in the tracking of low elevation targets is addressed through the use of two fixed radar frequencies. Since the multipath propagation depends on radar frequency and the acute elevation errors are often localized to intervals along the sensor-to-target range coordinate, fusion of dual frequency tracks is proposed for tracking low elevation targets. Two tracks are formed with elevation measurements obtained at two different waveform frequencies. The interacting multiple model (IMM) algorithm is used to estimate the target state for each waveform frequency. A "multipath effect present" mode and a "multipath effect absent" mode are included in the IMM algorithm so that the output error covariance will reflect the degradation in the accuracy of state estimates when multipath propagation is present. The state estimates of the two IMM algorithms are then used as track fusion algorithms to form an output state estimate. The results of extensive simulation studies of the tracking technique are given. <<ETX>>
Acute Metabolic Responses to Glucose and Fructose Supplementation in Healthy Individuals: A Double-Blind Randomized Crossover Placebo-Controlled Trial

The aim of this study was to investigate the impact of glucose (Glu), fructose (Fru), glucose and fructose (GluFru) and sucralose on blood glucose response in healthy individuals. Fifteen healthy individuals (five females, age of 25.4 ± 2.5 years, BMI of 23.7 ± 1.7 kg/m2 with a body mass (BM) of 76.3 ± 12.3 kg) participated in this double-blind randomized crossover placebo-controlled trial. Participants received a mixture of 300 mL of water with 1 g/kg BM of Glu, 1 g/kg BM of Fru, 0.5 g/kg BM of GluFru (each), and 0.2 g sucralose as a placebo. Peak BG values Glu were reached after 40 ± 13 min (peak BG: 141 ± 20 mg/dL), for Fru after 36 ± 22 min (peak BG: 98 ± 7 mg/dL), for GluFru after 29 ± 8 min (BG 128 ± 18 mg/dL), and sucralose after 34 ± 27 min (peak BG: 83 ± 5 mg/dL). Significant differences regarding the time until peak BG were found only between Glu and GluFru supplementation (p = 0.02). Peak blood glucose levels were significantly lower following the ingestion of Fru compared to the supplementation of Glu and GluFru (p < 0.0001) while Glu and GluFru supplementation showed no difference in peak values (p = 0.23). All conditions led to a significantly higher peak BG value compared to sucralose (p < 0.0001). Blood lactate increased in Glu (p = 0.002), Fru and GluFru (both p < 0.0001), whereas sucralose did not increase compared to the baseline (p = 0.051). Insulin levels were significantly higher in all conditions at peak compared to sucralose (p < 0.0001). The findings of this study prove the feasibility of combined carbohydrate supplementations for many applications in diabetic or healthy exercise cohorts.
A comparison between moire interferometry and strain gages for effective CTE measurement in electronic packages

High-sensitivity laser moire interferometry technique has proven to be invaluable in characterizing electronic packages. It is often contrasted to the classical strain gage technique as a more powerful, whole-field alternative for the characterization of electronic packages. In this paper, we present a systematic comparison of the accuracy of thermal strains measured using the moire technique to that obtained using strain gages. The effective thermal strains in approximately twenty printed circuit board specimens were measured using the two techniques. The results of the two techniques showed good overall correlation, but differed from each other by as much as 2.73 PPM. The possible sources of error in each technique are identified and discussed. Of practical significance, the measured effective coefficient of thermal expansion varied in wide range by as much as 5 PPM about the commonly used value of 17 PPM. This has been shown in a related study as causing a significant reliability impact for a plastic ball grid array package assembly.
