Resumen

This paper, proposes a method that by generating a pseudo random pattern, which will work as the watermark and the watermark is embedded during the quantization procedure. Then WSR (watermarking survival rate) is used to search for the optimized truncation points by running the EBCOT process, the truncation point is adjusted to stay at the bit plane boundary and it is used as the dividing point to split magnitude bits of wavelet coefficients, which is then sent to EBCOT for encoding. The final output is the J2K coded watermarked image. The results show that watermarked EBCOT image is nearly rate-distortion optimized, the decoder can recover the original image, the watermark can be detected effectively, and it is robust against geometric attacking such as rotating attack, cropping and scaling attack.

Resumen

Embedded block coding with optimised truncation (EBCOT) is a key algorithm in digital cinema (DC) distribution system. Though several high speed EBCOT architectures exist, all are not capable of meeting the DC specifications. To meet this challenge, the relationship between contents of a code block (CB) and context generation is studied. Our study reveals that it is difficult to predict number of contexts generated in a bit plane. Even the nature of number of contexts produced varies from CB to CB. In such a situation, it is difficult to ensure the frame rate requirement of DC. To avoid this uncertainty, a pass parallel, concurrent sample coding EBCOT architecture is proposed in this paper. It is capable of encoding one bit plane in 288 clock cycles under any circumstances. This design is prototyped on XC4VLX80-12 FPGA with multiple clock domains. After synthesizing, the bit plane coder (BPC) and MQ coder operate at 450 MHz and 123 MHz, respectively. In order to maintain synchronism among different clock domains, the BPC and MQ coder units are operated at 432 MHz and 108 MHz, respectively. This entails that the proposed design is capable of processing size 57 DC frames in a second.

Resumen

This paper presents a novel implementation of the JPEG2000 standard as a system on a chip (SoC). While most of the research in this field centers on acceleration of the EBCOT Tier I encoder, this work focuses on an embedded solution for EBCOT Tier II. Specifically, this paper proposes using an embedded softcore processor to perform Tier II processing as the back end of an encoding pipeline. The Altera NIOS II processor is chosen for the implementation and is coupled with existing embedded processing modules to realize a fully embedded JPEG2000 encoder. The design is synthesized on a Stratix IV FPGA and is shown to out perform other comparable SoC implementations by 39% in computation time.

Resumen

Motion-JPEG2000 is derived from Part 1 of the JPEG2000 standard and provides high quality image compression in video coding system. This paper presents a real-time Motion-JPEG2000 encoding which is built on a fixed-point digital signal processor (DSP) as a single-chip implementation. The design addresses on the system-level design considerations. Among several modules in JPEG2000, Embedded Block Coding with Optimized Truncation (EBCOT) algorithm contains the highest computation complexity and also becomes the bottleneck of JPEG2000. Two speed-improved methods are proposed to significantly reduce the processing time of EBCOT. The fast algorithm is used by processing the three coding passes in sequential and is very suitable to the execution on programming-based processor. For Motion-JPEG2000 implementation, a real-time encoding system is built on the single-chip DSP processor without any extra hardware support. The optimization techniques are also applied to enhance the performance. Due to the contribution on algorithm and implementation issue, the complexity of Motion-JPEG2000 is largely reduced. Simulation results show that the proposed system can process 30 frames per second in CIF size (352 × 288 pixels) with 4:2:0 video sequences. For SDTV size resolution (760 × 480 pixels), the system can achieve near 20 frames per second.

Resumen

Due to the huge advancement in technology, digitizing the multimedia content like text, images and videos has become easier. Everyday huge amounts of multimedia content are shared through the social networks using internet. Sometimes this multimedia content can be hacked by the hackers. This will lead to the misuse of the data. On the other hand, the medical content needs high security and privacy. Motivated by this, joint secured medical image compression–encryption mechanisms are proposed in this paper using multiscale transforms and symmetric key encryption techniques. The multiscale transforms involved in this paper are wavelet transform, bandelet transform and curvelet transform. The encryption techniques involved in this paper are international data encryption algorithm (IDEA), Rivest Cipher (RC5) and Blowfish. The encoding technique used in this paper is embedded block coding with truncation (EBCOT). Experimental results are done for the proposed works and evaluated by using various parameters like Peak Signal-to-Noise Ratio (PSNR), Mean Square Error (MSE), Image Quality Index (IQI) and Structural Similarity Index (SSIM), Average Difference (AD), Normalized Cross-correlation (NK), Structural Content (SC), Maximum difference (MD), Laplacian Mean Squared Error (LMSE) and Normalized Absolute Error (NAE). It is justified that the proposed approaches in this paper yield good results.

Resumen

To assess the reliability of electron beam computed tomography (EBCT), measurements of single-kidney renal blood flow (RBF), glomerular filtration rate (GFR), and intratubular contrast medium concentration (ITC) of radiographic contrast media were quantified in anesthetized pigs before and after acetylcholine-induced vasodilation and diuresis. EBCT measurements were compared with those obtained with intravascular Doppler and inulin clearance. The capability of EBCT to detect chronic changes in single-kidney function was evaluated in pigs with unilateral renal artery stenosis, and their long-term reproducibility in normal pigs was studied repeatedly at 1-mo intervals. EBCT-RBF (ml/min) correlated with Doppler-RBF as RBFEBCT = 45 + 1.07 ∗ RBFDoppler, r = 0.81. EBCT-GFR (ml/min) correlated with inulin clearance as GFREBCT = 11.7 + 1.02 ∗ GFRinulin, r = 0.80. During vasodilation, RBF and GFR increased, whereas ITC decreased along the nephron. In renal artery stenosis, single-kidney GFR decreased linearly with the degree of stenosis, and ITC increased along the nephron, indicating increased fluid reabsorption. EBCT-RBF, GFR, and ITC were similar among repeated measurements. This approach might be invaluable for simultaneous quantification of regional hemodynamics and function in the intact kidneys, in a manner potentially applicable to humans.

Resumen

ZusammenfassungDepressionen können erfolgreich behandelt werden, doch die Nachhaltigkeit psychotherapeutischer Effekte ist weiterhin eine Herausforderung. Expositionsbasierte Kognitive Therapie (EBCT) versucht, gleichzeitig Symptomatik und Depressionsvulnerabilität durch verstärkte kognitiv-emotionale Verarbeitung zu verändern. Die EBCT umfasst drei Behandlungsphasen: Aufbauphase zur Stabilisierung und Stärkung inklusive Achtsamkeitsübungen, Expositionsphase zur Bearbeitung depressionsrelevanter Selbstanteile mit emotionsfokussierten Methoden und Konsolidierungsphase zum Transfer erworbener Fertigkeiten und Erkenntnisse in den Alltag. In empirischen Studien konnten Belege für die Umsetzbarkeit der Methodenintegration sowie Akzeptabilität der Behandlung erbracht werden. In einer Vergleichsstudie zeigten sich große und der kognitiven Verhaltenstherapie (KVT) vergleichbare Prä-Post-Effekte der EBCT. Die kognitiv-emotionale Verarbeitung erfolgte hauptsächlich in der Expositionsphase und sagte das Therapieergebnis vorher. Die EBCT ist ein Beispiel für die erfolgreiche Integration ursprünglich theoriefremder Interventionen in die KVT. Zukünftige Entwicklungen der Depressionstherapie werden diskutiert.

Resumen

ABSTRACT The initial negative pressures of evacuated blood collection tubes (EBCT) and their in vitro performance as a rigid closed-suction surgical drain (CSSD) reservoir has not been evaluated in the scientific literature despite being described in both human and veterinary texts and journals. The initial negative pressures of EBCT sized 3, 6, 10, and 15 mL were measured and the stability of the system monitored. The pressure-to-volume curve as either air or water was added and maximal filling volumes were measured. Evacuated blood collection tubes beyond the manufacture’s expiration date were evaluated for initial negative pressures and maximal filling volumes. Initial negative pressure ranged from −214 mm Hg to −528 mm Hg for EBCT within the manufacturer’s expiration date. Different pressure-to-volume curves were found for air versus water. Optimal negative pressures of CSSD are debated in the literature. Drain purpose and type of exudates are factors that should be considered when deciding which EBCT size to implement. Evacuated blood collection tubes have a range of negative pressures and pressure-to-volume curves similar to previously evaluated CSSD rigid reservoirs. Proper drain management and using EBCT within labeled expiration date are important to ensure that expected negative pressures are generated.

Resumen

Natural organic matter (NOM) in drinking water is a complex mixture of organic compounds. Some of the compounds are not biodegradable, while others are quickly biodegradable and a third group is more resistant to biodegradation. To have a better understanding of the biofiltration process in drinking water treatment, it is important to identify the elements of the quickly and slowly biodegradable NOM and to characterize the biodegradation rate of each element. In this study, an ozonated NOM solution was used as the substrate. The NOM was isolated from a groundwater in Germany using ion-exchange resins. The ozone dose was 0.35 mg O3/mg DOC (dissolved organic carbon). Previously bioacclimated sand was used as filter media and biomass source and was homogeneously distributed in the filter prior to each run. The substrate removal was evaluated by DOC, biodegradable DOC (BDOC), assimilable organic carbon (AOC), aldehyde and ketoacid analyses. When expressed in terms of the empty bed contact time (EBCT), the results showed that filter velocity in the range of 1.5 to 15 m/hr had no impact on substrate removal. This implies that substrate utilization, not external mass transfer, is the rate limiting step for substrate removal in drinking water biofilters. In this study, compounds or NOM fractions are termed quickly biodegradable if they are removed in the first three minutes of EBCT. 15% of the DOC was removed by the biofilter within three minutes of EBCT and was termed the quickly biodegradable fraction. The BDOC fraction of the ozonated solution was determined to be 40 to 45% of the DOC. In terms of BDOC, about one third of the total BDOC was quickly biodegradable. The AOC results show that about 90% of the total AOC was utilized by Spirillum sp. NOX (AOC-NOX). Most of the AOC was quickly biodegradable and was removed within one minute of EBCT. For aldehydes, glyoxal and methyl glyoxal were removed to below the detection limit after two minutes of EBCT. However, only 60% of formaldehyde removal was achieved in the first two minutes of EBCT, and no additional removal was achieved with increasing EBCT. Additionally, no significant removal of acetaldehyde was observed. The results of ketoacids show that their utilization rates were very high. More than 90% of glyoxylic acid and pyruvic acid were removed within one minute of EBCT.

Resumen

The main Nakdong river water mixed with polluted Kumho river was used as raw water in this research. The removal efficiencies of TOC and UV254 nm absorbance in the ultrafiltration process were both approximately 15% higher than those in the coagulation/rapid sand filtration process. In the biological activated carbon filter, the ammonia nitrogen removal efficiency goes up to over 90% after 35 days of operation in the early spring at empty bed contact time (EBCT) of 25 min. At EBCT of 25 min, the removal of TOC and UV254 nm absorbance were higher by about 5% and 10%, respectively, than at EBCT of 10 min. By the combination of ozonization to ultrafiltration-biological activated carbon process, the AOX and THM formation potential were effectively reduced.

Resumen

P25 Electron Beam Computed Tomography (EBCT) is used to detect coronary artery calcification (CAC), a marker of atherosclerosis. The EBCT was used to determine the presence of CAC in a population of very fit individuals. EBCT determined the calcification scores in 436 asymptomatic individuals (400 males 36 females, mean age 43.5±3.2 yrs, range 33 to 56 yrs). All underwent extensive cardiovascular and fitness evaluations including medical, fitness and nutritional histories; lipid profiles, fasting blood sugars, homocysteine, and lipoprotein(a) levels. Individuals underwent a physical examination, resting electrocardiogram, measurements of strength and flexibility, a maximal symptom-limited treadmill test, and a direct measurement of maximal oxygen consumption. CAC was detected by EBCT scan (3 mm thick, ECG-triggered, axial images) and quantified using the Agatston scoring technique. EBCT scores ranged from 0 to 2112 and were classified into standard categories - insignificant atherosclerosis: calcium <10 (n=364 83.3%); mild atherosclerosis: calcium 10-99 (n=31 13.5%); moderate atherosclerosis: calcium 100-399 (n=7 1.6%); and marked atherosclerosis: calcium >399 (n=7 1.6%). CAC was more likely in individuals who had an elevated LDL-Chol level (p≤.001) and CHOL/HDL ratio (p≤.001), but there was wide variance. Factors that had little or no correlation included fitness parameters as determined by strength measurements, aerobic capacity or bodyfat determination. Individuals with family history of early CAD had tendency for the development of CAC but again there was wide variation in the severity of the calcium score. Of the four individuals who had CAC scores over 1000, two subsequently sustained a myocardial infarction despite previous normal maximal exercise treadmill tests. In this group exercise thallium studies were not predictive for future events. It is difficult to detect CAD in fit, asymptomatic middle-aged individuals. EBCT is helpful in defining a high risk CAD group that is not readily determined by standard risk factors.

Resumen

The high number of critical illness cases and the rising medical cost affect the number of insurance claimed. It can be a problem for the insurance company in estimating future claim trend to decide the risk premium cost, so that we need a method to solve the problem which is called Empirical Bayes Credibility Theory (EBCT). Based on that information, the goal of this research is estimating the risk premium cost for critical illness cases using EBCT method. In this research, a large simulation of the expected claim data of critical illness policyholders is used, which are grouped by age and gender. In processing data by applying the EBCT method, the credibility factor is determined first, then the size of the risk premium can be estimated, with the calculation results obtained by a different estimate of the risk premium for each age group based on gender.

Resumen

The objectives of this pilot-scale study were to optimize backwash frequency and empty bed contact time (EBCT) of biofilters treating ozonated surface water from Lake Ontario. Performance was benchmarked in terms of the reduction of turbidity, dissolved organic carbon (DOC), disinfection by-product (DBP) precursors, and ultrafiltration foulants (biopolymers). Increasing the EBCT from 4 to 8 min resulted in a higher reduction of DOC (5%), trihalomethane (THM4) and haloacetic acid (HAA9) precursors (∼12%) without negatively impacting effluent turbidity (consistently below 0.4 NTU), while biopolymer removal remained unaffected (2%). The impact of varying backwash frequency (5, 10, and 25 day intervals) was also compared for biofilters operated at an EBCT of 4 min. Results showed no impact of extended run times (up to 25 days) on DOC or DBP precursor removal; however turbidity removal was affected beyond 15 days of operation. Backwashing biofilters at 10 vs 5 day intervals would result in a reduction of backwash water, energy consumption and amount to nearly $17,000 in savings for the utility.

Resumen

Abstract. Drinking water companies (are intending to) implement advanced oxidation processes (AOP) in their treatment schemes to increase the barrier against organic micropollutants (OMPs). It is necessary to decompose the excessive hydrogen peroxide after applying AOP to avoid negative effects in the following, often biological, treatment steps. A drinking water company in the western part of the Netherlands investigated decomposition of about 5.75 mg L−1 hydrogen peroxide in pre-treated Meuse river water with different catalysts on pilot scale. In down flow operation, the necessary reactor empty bed contact time (EBCT) with the commonly used granulated activated carbon (GAC) and waste ground water filter gravel (MCFgw) were found equal with 149 s, corresponding with a conversion rate constant r of 0.021 s−1. The EBCT of the fine coating of ground water filter gravel (MC) was significantly shorter with a little more than 10 s (r = 0.30 s−1). In up flow operation, with a flow rate of 20 m h−1, the EBCT of coating MC increased till about 100 s (r = 0.031 s−1), from which can be concluded, that the performance of this waste material is better compared with GAC, in both up and down flow operation. The necessary EBCT at average filtration rate of full scale dual layer filter material (MCFsw) amounted to 209 s (r= 0.015 s−1). Regarding the average residence time in the full scale filters of 700 s, applying AOP in front of the filters could be an interesting alternative which makes a separate decomposition installation superfluous, on the condition that the primary functions of the filters are not affected.
