Produced Water Management For Sustainable Reinjection - Bench Scale Tests To Remove And Destroy KHI (2014)

Abstract Dolphin Energy Limited's (DEL) production scheme is based on a wet transport of well effluents from offshore platforms (DOL-1 and DOL-2) to the onshore treatment plant. At the onshore receiving facilities, sour gas is routed to gas sweetening, condensate is stabilized and treated and produced sour water is routed to water treatment units. Since the plant startup in 2006, non-chemically contaminated waste water is used for irrigation after treatment. Produced waste water and chemically contaminated waste water are re-injected into a deep reservoir without any major treatment further to H2S stripping, oil skimming, pH control and multi-media filtration. However, local authorities have expressed their concerns about the quality of water injected and the potential risk of long term injectivity loss. Indeed, as sealines need to be protected all year round against corrosion using a Corrosion Inhibitor (CI) and hydrate formation during winter by using Kinetic Hydrate Inhibitor (KHI), produced water recovered onshore is chemically contaminated with polymer based chemicals. As KHI could damage the reservoir, it has to be removed from produced water prior to reinjection. However, no technology was clearly available and referenced for this application. Dolphin Energy launched numerous bench scale tests with a third party laboratory to identify the best treatment scheme to remove KHI. The paper will first explain the overall strategy put in place to identify applicable processes. Then, it will describe the laboratory tests on produced water for KHI removal and destruction. Eventually, results will be presented and compared in order to conclude with applicable treatment schemes that would remove and destroy KHI from produced water for sustainable reinjection.
Leakage Detection in Water Networks (2005)

A health monitoring tool for leakage identification in water networks is presented. It is assumed that the water heads at the network’s nodes can be measured in different locations of some inspected area. Then, making use of the analytical network model of the actual installation and using the proposed Virtual Distortion Method (VDM) approach, leakages (single as well as in multiple locations, and their intensities) can be detected and identified in the system. The identification methodology takes advantage of a gradient-based optimization technique.
Operation Prediction for Context-Aware User Interfaces of Mobile Phones (2009)

Nowadays mobile phones are multifunctional devices that provide us with various useful applications and services anytime and anywhere. However, people are sometimes unable to access an appropriate application due to the complexity and depth of the menu structure. This paper focuses on a feasibility study of operation prediction using observable attributes to realize self-optimization functionality in the mobile phones that can automatically and adaptively change their user interface (UI) according to user characteristics and circumstances. Machine learning (ML) is a promising technology for enhancing UI. However, few studies have been conducted for the operation prediction using the ML framework. We analyzed the real usage data collected by practical mobile phones and found that ML-based prediction methods were feasible to estimate future operations, and to provide context-aware UI.
Maintenance management decision model for preventive maintenance strategy on production equipment (2011)

In industries, Preventive Maintenance (PM) is not a new practice to minimise the sudden breakdown of production machine. PM will be performed at predetermine intervals to provide a balance between failure cost and component utilisation (aging). However, most of PM interval is based on experience or original equipment manufacturer (OEM) recommendations. Consequently, the benefits from PM are not fully obtained because the current machine state is not considered. The aim of this paper is to propose a maintenance management decision model for PM application. The main objective of the model is to revise the PM interval based on current machine state. The proposed model provides step-by-step procedure from data identification, classification, evaluation until determination of the revised PM interval.

Continuous Cell Lines from the Tick Hyalomma anatolicum anatolicum (1991)

The establishment of 5 continuous cell lines from embryonic tissues of the tick Hyalomma anatolicum anatolicum is reported. Each line comprises 2 or more cell types; they are maintained at 28 C and 32 C in L-15/H-Lac medium with 20% fetal calf serum, and have been cryopreserved successfully. Sustained and consistent growth was achieved only after 12-41 mo in culture.
Vanadyl−Thiazolidinedione Combination Agents for Diabetes Therapy (2002)

A series of vanadium compounds, chelated by ligands containing a thiazolidinedione moiety as an additional insulin-enhancing component, were produced in this study to create potentially synergistic compounds. A set of four bifunctional ligand precursors were synthesized: (+/-)-5-[4-[(5-hydroxy-4-oxo-4H-pyran-2-ylmethyl)amino]benzyl]thiazolidine-2,4-dione (HL(1)), (+/-)-5-[4-[(5-hydroxy-1-methyl-4-oxo-1,4-dihydro-pyridin-2-ylmethyl)amino]benzyl]thiazolidine-2,4-dione (HL(2)), 5-[4-(5-hydroxy-4-oxo-4H-pyran-2-ylmethoxy)benzylidene]thiazolidine-2,4-dione (HL(3)), and (+/-)-5-[4-(5-hydroxy-4-oxo-4H-pyran-2-ylmethoxy)benzyl]thiazolidine-2,4-dione (HL(4)), each containing a metal chelating portion as well as a thiazolidinedione moiety. From this set of ligand precursors, air-stable VO(L(1))(2), VO(L(3))(2), and VO(L(4))(2) were prepared. The four ligand precursors and three complexes were tested for insulin-enhancing potential in STZ-diabetic rats and compared to rosiglitazone and BMOV, respectively. Both the ligand precursors HL(1) and HL(3) showed enhanced activity compared with that of rosiglitazone. The complex VO(L(3))(2) showed the most efficacious hypoglycemic effects in this study; however, neither additive nor synergistic effects were observed using this acute animal model.
Adaptive Road Following using Self-Supervised Learning and Reverse Optical Flow (2005)

The majority of current image-based road following algorithms operate, at least in part, by assuming the presence of structural or visual cues unique to the roadway. As a result, these algorithms are poorly suited to the task of tracking unstructured roads typical in desert environments. In this paper, we propose a road following algorithm that operates in a selfsupervised learning regime, allowing it to adapt to changing road conditions while making no assumptions about the general structure or appearance of the road surface. An application of optical flow techniques, paired with one-dimensional template matching, allows identification of regions in the current camera image that closely resemble the learned appearance of the road in the recent past. The algorithm assumes the vehicle lies on the road in order to form templates of the road's appearance. A dynamic programming variant is then applied to optimize the 1-D template match results while enforcing a constraint on the maximum road curvature expected. Algorithm output images, as well as quantitative results, are presented for three distinct road types encountered in actual driving video acquired in the California Mojave Desert.
Pedestrian detection combining RGB and dense LIDAR data (2014)

Why is pedestrian detection still very challenging in realistic scenes? How much would a successful solution to monocular depth inference aid pedestrian detection? In order to answer these questions we trained a state-of-the-art deformable parts detector using different configurations of optical images and their associated 3D point clouds, in conjunction and independently, leveraging upon the recently released KITTI dataset. We propose novel strategies for depth upsampling and contextual fusion that together lead to detection performance which exceeds that of the RGB-only systems. Our results suggest depth cues as a very promising mid-level target for future pedestrian detection approaches.
Hybrid predication model for instruction level parallelism (2002)

This paper presents a hybrid predication model in analogy to the delayed branching technique with overlapped delayed slots by integrating two different predication models. Predicated-execution is considered a promising branch handling technique. A few models have been proposed for predicated-execution, the most known model has succeeded to provide ILP processors with enough parallel instructions for efficient resource utilization. Unfortunately, false parallelism is introduced by the instructions provided from the null paths (large dynamic code expansion). Another predicated-execution model has managed to decrease the dynamic code expansion, with the cost of limiting the parallelism exploited and increasing the static code expansion. The presented hybrid predication model managed to integrate the advantages of the two models by decreasing the code expansion both dynamically and statically especially for conditional code structures included within loops. The various conducted experiments aimed to provide an evaluation for the proposed model via simulation. The results proved that the presented hybrid predication model can achieve better utilization of register and shorter schedules with the same issue-width compared with the other existing models.
A novel power saving scheme for WDM-PON with centralized light sources (2009)

Middle and upper tropospheric carbon monoxide mixing ratios as measured by a satellite‐borne remote sensor during November 1981 (1986)

Mixing ratios of tropospheric carbon monoxide measured by a gas filter radiometer carried aboard the space shuttle during November 1981 are reported. The data represent average mixing ratios in the middle and upper troposphere between 38°N and 38°S latitude. Approximately 10,000 individual measurements were obtained in each of the two channels of the instrument. The data are presented in the form of plots that show the individual carbon monoxide mixing ratio measurements as a function of latitude and longitude and in the form of maps that show the data averaged over 5° latitude by 5° longitude squares. The data show relatively little variation in the mixing ratio in the southern hemisphere; however, the data from both the tropics and the northern hemisphere show strong gradients with both latitude and longitude.
Vibration Therapy in Management of Delayed Onset Muscle Soreness (DOMS) (2014)

Both athletic and nonathletic population when subjected to any unaccustomed or unfamiliar exercise will experience pain 24-72 hours postexercise. This exercise especially eccentric in nature caused primarily by muscle damage is known as delayed-onset muscle soreness (DOMS). This damage is characterized by muscular pain, decreased muscle force production, reduce range of motion and discomfort experienced. DOMS is due to microscopic muscle fiber tears. The presence of DOMS increases risk of injury. A reduced range of motion may lead to the incapability to efficiently absorb the shock that affect physical activity. Alterations to mechanical motion may increase strain placed on soft tissue structures. Reduced force output may signal compensatory recruitment of muscles, thus leading to unaccustomed stress on musculature. Differences in strength ratios may also cause excessive strain on unaccustomed musculature. A range of interventions aimed at decreasing symptoms of DOMS have been proposed. Although voluminous research has been done in this regard, there is little consensus among the practitioners regarding the most effective way of treating DOMS. Mechanical oscillatory motion provided by vibration therapy. Vibration could represent an effective exercise intervention for enhancing neuromuscular performance in athletes. Vibration has shown effectiveness in flexibility and explosive power. Vibration can apply either local area or whole body vibration. Vibration therapy improves muscular strength, power development, kinesthetic awareness, decreased muscle sore, increased range of motion, and increased blood flow under the skin. VT was effective for reduction of DOMS and regaining full ROM. Application of whole body vibration therapy in postexercise demonstrates less pressure pain threshold, muscle soreness along with less reduction maximal isometric and isokinetic voluntary strength and lower creatine kinase levels in the blood.
Process Identification and PID Controller Tuning in Multivariable Systems. (1998)

A closed-loop identification procedure for multivariable systems utilizing set-point change in a rectangular pulse type, is proposed and applied to two example systems. The identified model composed of transfer functions of the first order plus dead time model is decoupled and separated into multiple single-input/single-output (SISO) loops. Then, the SISO PI/PID control loops are tuned using combined open-loop and closed-loop tuning guidelines.The performance of the control system is examined in the set-point tracking and regulatory performances and compared with the BLT tuning method. It is found that the performance of this study is better than that of the BLT tuning. Also, it is proved that the proposed identification method requires short identification time and leaves no disturbance in process output.
Leveraging Identity-Based Cryptography for Node ID Assignment in Structured P2P Systems (2007)

Structured peer-to-peer systems have grown enormously because of their scalability, efficiency and reliability. These systems assign a unique identifier to each user and object. However, current assignment schemes allow an adversary to carefully select user IDs and/or simultaneously obtain many pseudo-identities-leading ultimately to an ability to disrupt the P2P system in very targeted (and dangerous) ways. In this paper, we propose novel ID assignment protocols based on identity-based cryptography. This approach permits the acquisition of node IDs to be tightly regulated without many of the complexities and costs associated with traditional certificate solutions. We broadly consider the security requirements of ID assignment and present three protocols representing distinct threat and trust models. A detailed empirical study of the protocols is given. Our analysis shows that the cost of our identity-based protocols is nominal, and that the associated identity services can scale to millions of users using a limited number of servers.
Production of Hexanol as the Main Product Through Syngas Fermentation by Clostridium carboxidivorans P7 (2022)

The production of hexanol from syngas by acetogens has gained attention as a replacement for petroleum-derived hexanol, which is widely used in the chemical synthesis and plastic industries. However, acetogenic bacteria generally produce C2 compounds (e.g., acetate and ethanol) as the main products. In this study, the gas fermentation conditions favorable for hexanol production were investigated at different temperatures (30-37°C) and CO gas contents (30-70%) in batch gas fermentation. Hexanol production increased from 0.02 to 0.09 g/L when the cultivation temperature was lowered from 37 to 30°C. As the CO content increased from 30 to 70%, the CO consumption rate and hexanol production (yield, titer, and ratio of C6 compound to total products) increased with the CO content. When 70% CO gas was repeatedly provided by flushing the headspace of the bottles at 30°C, the total alcohol production increased to 4.32 g/L at the expense of acids. Notably, hexanol production (1.90 g/L) was higher than that of ethanol (1.20 g/L) and butanol (1.20 g/L); this is the highest level of hexanol produced in gas fermentation to date and the first report of hexanol as the main product. Hexanol production was further enhanced to 2.34 g/L when 2 g/L ethanol was supplemented at the beginning of 70% CO gas refeeding fermentation. Particularly, hexanol productivity was significantly enhanced to 0.18 g/L/day while the supplemented ethanol was consumed, indicating that the conversion of ethanol to acetyl-CoA and reducing equivalents positively affected hexanol production. These optimized culture conditions (gas fermentation at 30°C and refeeding with 70% CO gas) and ethanol supplementation provide an effective and sustainable approach for bio-hexanol production.
Dental care access among individuals with Down syndrome in France (2000)

The aim of this study was to compare levels of dental care utilization, receipt of dental services, and oral hygiene habits between a sample of individuals with Down syndrome (DS) and their siblings. Data were collected by means of a recently validated, French-language, questionnaire measured of oral health and its related problems for individuals with DS. A cross-sectional survey was undertaken of parents of children with DS attending a national meeting for families and carers of individuals with DS in France. Older individuals with DS were significantly more likely to visit a dentist regularly than their older non-DS siblings, but the group with DS was significantly less likely to have received any dental treatment. The group with DS was significantly more likely to have difficulty finding both medical and dental services. Parents were nearly twice as likely to report problems finding dental services for their child with DS as they were medical services. In a multiple logistic regression analysis within the DS group, it was found that older age, regular speech therapy and ophthalmology consultations, and reports of no difficulty finding a dentist were independently associated with increased odds for regular dental consultations. Analysis of the findings suggests that the parents of children with DS in France frequently encounter problems of access to oral health care and that individuals with DS are less likely to receive dental services than are their non-DS siblings.
Quantification of metal‐acid balance in hydroisomerization catalysts: A step further toward catalyst design (2016)

A methodology was developed to interpret the results of n‐paraffins hydroisomerization over bifunctional catalysts based on two simple kinetic models used consecutively. First, a macrokinetic model was used to obtain the corresponding turnover frequency over the acid sites and the maximum of C 16 isomer yield. Second, a dual‐function model was used to correlate these catalytic descriptors to the ratio of metal to acid sites of the catalyst. To illustrate the methodology, Pt/HBEA and Pt/HUSY catalysts with different Pt loadings were evaluated. The impact of metal‐acid balance on the catalytic turnover frequency and the maximal C 16 isomer yield were adequately captured for the bifunctional HUSY and HBEA catalysts. Moreover, the parameters of the dual‐function model revealed to be intrinsic to the catalytic properties of the zeolite under the scope. This methodology is believed to be of interest for information‐driven catalyst design for the hydroisomerization of n‐paraffins. © 2017 American Institute of Chemical Engineers AIChE J , 63: 2864–2875, 2017
Features of Architecture Description Languages (1995)

Introduction 1.1 Background: system architecture for system development? The characteristic approach in mature engineering disciplines (e.g. civil and chemical engineering) is to build systems (e.g., buildings or chemical plants) from known solutions such as proven designs and existing components [Shaw90,D&apos;Ippolito89]]. Engineers in mature disciplines also put great emphasis on proactively avoiding costly problems by evaluating the system before it is built [Liu87]. Models of the system&apos;s architecture are important tools for applying known solutions and doing early evaluation in mature engineering disciplines. In software engineering, the corollary is modelling the software architecture. By software architecture, we mean the components into which a system is divided at the level of system organization, and the ways in which those components communicate, interact, and coordinate with each other [Garlan93] [Shaw95]. Examples of components include modules, processes or ta
Dynamic frame-skipping in video transcoding (2002)

This paper investigates the dynamic frame skipping strategy in video transcoding. To speed up the operation, a video transcoder usually reuses the decoded motion vectors to reencode the video sequences at a lower bit-rate. When frame skipping is allowed in a transcoder, those motion vectors can not be reused because the motion vectors of the current frame is no longer estimated from the immediate past frame. To reduce the computational complexity of motion vectors reestimation, a bilinear interpolation approach is developed to overcome this problem. Based on these interpolated motion vectors, the search range can be much reduced. Furthermore, we propose a frame rate control scheme which can dynamically adjust the number of skipped frames according to the accumulated magnitude of the motion vectors. As a result, the decoded sequence can present much smoother motion.
Nasal Valve Surgery Improves Disease-Specific Quality of Life (2005)

In patients with symptomatic nasal obstruction and nasal valve compromise, surgical repair of the nasal valve improves disease-specific QOL. Physician rating of degree of nasal obstruction was found to be significantly correlated with patient-reported QOL.
Aggregation structure and surface properties of immobilized organosilane monolayers prepared by the upward drawing method (1994)

Octadecyltrichlorosilane [OTS, CH3(CH2)17SiCl3] and [2-(perfluorooctyl)ethyl] trichlorosilane [FOETS, CF3(CF2)7CH2CH2SiCl3] monolayers were prepared on a water surface. The monolayers of OTS and FOETS amphiphiles were polymerized to form a Si–O–Si linkage on the water subphase. The polymerized monolayers were transferred onto a glass plate or silicon wafer surface by the upward drawing method and were covalently bonded to the Si–OH groups of the glass or silicon wafer surface. Electron diffraction patterns revealed that the OTS monolayer was in a crystalline state, while the FOETS monolayer was in an amorphous state at 293 K. The bright field image showed homogeneous molecular aggregation in the OTS and FOETS monolayers. The atomic force microscopic and frictional force microscopic images of the OTS/FOETS mixed monolayers distinctly showed a phase-separated structure. Deposition of the OTS, FOETS, and OTS/FOETS monolayers on the substrate was confirmed by attenuated total reflection Fourier transform infrared spectroscopy and x-ray photoelectron spectroscopy. A highly hydrophobic property was observed for OTS, FOETS, and OTS/FOETS monolayer immobilized surfaces. Dynamic contact angle measurements indicated that the surface structure of these monolayers did not show reorganization upon environmental change because of polymerization and the formation of a covalent bond between the monolayer and the substrate surface.
