GLOBAL OPTIMIZATION OF MULTIPHASE FLOW NETWORKS IN OIL AND GAS PRODUCTION SYSTEMS

A mathematical program for finding the optimal oil production rates in an oil production system is developed. Each well may be manipulated by injecting lift gas and adjusting a production choke. The oil production from the wells may be restricted with multiple constraints in the maximum oil flow rate, water flow rate, liquid flow rate, and gas flow rate. The wells may also be restricted with a maximum total lift gas rate. In oil production systems with sub sea wells, flow lines are often shared between two or more wells. The pressure in the production manifold will in such configurations be affected by the flow from the wells. The commonly used models based on gas lift performance curves (GLPC) no longer apply to these problems due to changing pressure conditions in the production manifold. Because of this, a model of the flow line is also required to get more accurate results. This work incorporates such a model. A piecewise linear approximation is proposed. This makes it possible to find a proven global optimum, within the approximation, for the optimization problem. The problem is formulated as a mixed integer linear program and solved with a commercial branch and cut solver.
Psychological capital, Big Five traits, and employee outcomes

Purpose – The aim of this paper was to examine the incremental validity of positive psychological capital (PsyCap) in predicting several important employee outcomes while controlling for a full range of personality traits. Design/methodology/approach – Using a cross-sectional field study design, the authors collected data from 373 employees in South Korea. Findings – Hierarchical multiple regression analyses revealed that employees' PsyCap is related to their perceived performance, turnover intention, work happiness, and subjective well-being, even after controlling for the Big Five personality traits. Research limitations/implications – By controlling for the Big Five traits, this study was able to evaluate the role of PsyCap more precisely. However, as the data were collected from the same source at one point in time, common method variance is a potential issue. Practical implications – The findings suggest that managers need to focus on developing employees' PsyCap, given its unique effect on the outco.
Murine esBAF chromatin remodeling complex subunits BAF 250 a and Brg

Background: Cellular differentiation and reprogramming are accompanied by changes in replication timing and 3D organization of large-scale (400 to 800 Kb) chromosomal domains (‘replication domains’), but few gene products have been identified whose disruption affects these properties. Results: Here we show that deletion of esBAF chromatin-remodeling complex components BAF250a and Brg1, but not BAF53a, disrupts replication timing at specific replication domains. Also, BAF250a-deficient fibroblasts reprogrammed to a pluripotency-like state failed to reprogram replication timing in many of these same domains. About half of the replication domains affected by Brg1 loss were also affected by BAF250a loss, but a much larger set of domains was affected by BAF250a loss. esBAF binding in the affected replication domains was dependent upon BAF250a but, most affected domains did not contain genes whose transcription was affected by loss of esBAF. Conclusions: Loss of specific esBAF complex subunits alters replication timing of select replication domains in pluripotent cells.
Serum uric acid: a forgotten prognostic marker in acute coronary syndromes?

Background: Serum uric acid (UA) has been shown to be an independent predictor of outcome in the general population and in patients with heart failure. There are, however, limited data regarding the prognostic value of UA in the context of acute coronary syndromes (ACS) particularly in medium-term follow up and the available results are contradictory. Materials and methods: Study of consecutive patients admitted with an ACS (with and without ST-segment elevation) at a single-centre coronary care unit. Primary endpoint was all-cause mortality at 1-year follow up. We evaluated if serum UA is an independent predictor of outcome and if it has any added value on top of GRACE risk score for risk prediction. Results: We included 683 patients, mean age 64±13 years, 69% males. In-hospital and 1-year mortality were 4.5 and 7.6% respectively. The best cut-off of UA to predict 1-year mortality was 6.25 mg/dl (sensitivity 59%, specificity 72%) and 30.2% of the patients had an increased UA according to this cut off. Independent predictors of UA were male gender (β= 0.078), body mass index (β=0.163), diuretics before admission (β=0.142), and admission serum creatinine (β=0.403). One-year mortality was significantly higher in patients with increased UA (15.5 vs. 4.2%, p<0.001; log rank, p<0.001). After adjustment, both increased UA as a categorical variable (HR 2.25, 95% CI 1.23–4.13, p=0.008) and as a continuous variable (HR 1.26, 95% CI 1.13–1.41, p<0.001) are independent predictors of mortality. The AUC increases only slightly after inclusion of UA in the model with GRACE risk score (from 0.78 to 0.79, p=0.350). Both models had a good fit; however, model fit worsened after inclusion of UA. Overall, the inclusion of UA in the original was associated with an improvement in both the net reclassification improvement (continuous NRI=44%), and the integrated discrimination improvement (IDI=0.052) suggesting effective reclassification. Conclusions: Serum UA is an independent predictor of all-cause mortality in medium-term after the whole spectrum of ACS and has an added value for risk stratification.
Toward a Virtual Edge Service Provider: Actor-Critic Learning to Incentivize the Computation Nodes

The growing development of computation-intensive applications has considerably increased the demand for computing resources in the network. Many of these applications require computations with low delays. Edge computing, which offers computing resources at the edge of the network, is a prominent solution. However, an edge service provider might not have sufficient resources at the edge to satisfy the demands of its users. Computation offloading can fill the gap by letting the service provider transfer the users' computational tasks to other computation nodes (CNs). Nevertheless, due to the imposed costs, CNs are not always interested in sharing their computation capacity. This article considers the concept of a virtual edge service provider, and studies an incentive mechanism to motivate the CNs to share their resources. We formulate the problem as a Stackelberg game and present a complete information analysis. We prove the existence and uniqueness of the game equilibriums. However, the complete information scenario is not accessible in practice due to privacy reasons. Therefore, we propose a soft actor-critic algorithm as an incomplete information method using deep reinforcement learning. Finally, through extensive numerical evaluations, we show that the incomplete information method converges to the same equilibrium that the complete information analysis proved.
Made in Criticalland: Designing Matters of Concern

Critical and theoretical concepts and theories are now firmly embedded within design education, but to what goal? How will the practice of design develop and change under the ethos of critical inquiry? Indeed, what version of ‘critique’? Taking inspiration from Latour’s essay 'Why Has Critique Run out of Steam? From Matters of Fact to Matters of Concern (2004), this paper will outline how we are introducing concepts and methods derived from science and technology studies (STS), principally developments in actor-network theory (ANT), as part of the BA and MA design programmes at Goldsmiths. To begin, we provide a brief reading of Latour’s essay, discussing its relevance for design education. In doing so we aim to propose an alternative version of critical practice: a criticality that is oriented towards a non-reductive empirical realism tracing the complex messy entanglements of societies with all their strange, weird and wonderful hybrid objects. At the core of the paper, then, is the question of how designers might adopt a realist empirical approach towards the research of societies, actors and networks, whilst allowing for creative speculation. To address this question we present two case studies to highlight the benefits and shortfalls of an STS and ANT inspired approach to design. The first describes a series of workshops with which we encourage our students to adopt the concepts and methods of STS and ANT as part of their design practice. In the second case study we present a design brief in which we ask students to seriously address fictional futures through the associative mingling of statistical entities. In doing so we are exploring how design can address the mediation of expectations and temporality: how, for example, designers might act with ‘matters of concern’ to prospect futures. Each of the case studies highlights a problematic found within both ANT and Design: the first issue is one of truncation. How, in accepting an empirical logic of connectivity, designers delimited and edit their networks of observation and influence. The second case study focuses on the issue of temporality, or more specifically 'future orientation', 'potential' or 'prospect'. Here, design can be seen as a means of ‘departure’ in the material-semiotic lives of objects.
Tool Use Traditions in Nonhuman Primates: The Case of Tufted Capuchin Monkeys

Tool use was once a major defining feature of “human nature”. If the findings about the spontaneous use of tools by wild chimpanzees (Pan troglodytes) forced us to rethink traditional views on the “unique and exclusive” character of human technological abilities, the discovery of similar behaviors in a few monkey species – one Old World monkey (Macaca fascicularis), and one genus of New World monkeys (Sapajus spp) – leads us to broader questions, focusing our attention not on phylogenetic proximity, but, rather, on the cognitive, ecological and social conditions and mechanisms fostering the emergence of tool use and behavioral traditions. The use of tools does not imply any particular underlying cognitive mechanisms: In most cases, it involves a single, “species-typical” behavior, which may look quite “hard-wired”. Even among tool-using birds, the development of such abilities seems to rely mostly on individual learning, building on innate predispositions. In the case of nonhuman primates’ toolkits, however, there is growing evidence of behavioral variation that cannot be explained just by genetic differences between populations, nor by different environmental pressures and affordances, suggesting the results of socially biased learning. The comparative approach, by itself, cannot provide hard evidence of behavioral traditions: Developmental studies, as well as field experiments, are helping to unravel the cultural nature of primate tool use. Although human culture (cumulative, symbolic) may depend on special cognitive features, such as “Theory of Mind”, enabling shared intentions, imitation, and purposeful teaching, simpler mechanisms, such as “stimulus enhancement”, can support the establishment of behavioral traditions. Moreover, the lasting changes in the environment produced by some forms of tool use can be seen as instances of “niche construction” optimizing naive observers’ learning opportunities.
Data Security Using Graphical Password and AES Algorithm for E-mail system

The main intention of this project is Data Security using the Text-based Graphical pass-word Schemas using color Combination for E-mail system. It secure users data from shoulder surfing attack. Since conventional password schemes are vulnerable to shoulder surfing, many shoulder surfing resistant graphical password schemes have been proposed. However, as most users are more familiar with textual passwords instead of pure graphical passwords. Unfortunately, none of existing text-based shoulder surfing resistant graphical password schemes is both secure and efficient enough. In this paper, we propose an improved text-based shoulder surfing resistant graphical password scheme by using colors for E-mail system. Access to computer systems is most often based on the use of alphanumeric passwords. However, users have interested on graphical password, therefore we have been proposed text based graphical password scheme for E-mail application . With the vast introduction of the wireless world, the exchanged information now is more prone to security attacks than ever. In this paper Encryption and decryption process also done to transfer data through E-mail securely. To make the Authentication between two intended users along with the security, server is used. With the help of server, both sender and receiver will get validated. In this project we have to use the Authentication purpose password Schemas using the Text Based Graphical password for the Login for E-mail system.
Face Recognition Stationed on DT-CWT and Improved 2DPCA employing SVM Classifier

Wavelet Transform is basically used for magnitude depletion. It is used for axing the proportion of picture. Including good multi-resolution and multi-scale analysis, wavelet transform also has the propensity of denoting local signal attribute by using the high and low pass filtering, image can be decomposed into divergent scales of approximation components. But in wavelet transform, the higher decomposition layers will lost a lot of information, by which reduce the recognition rate. 2DPCA is a sort of image extraction method deal directly with image data and does not need dimension reduction. It is undertaking image data without step of vectorization. However 2DPCA algorithm reduces the computational complexity, it takes up more storage space. In that paper proposed an advanced technique which is stationed on dual-tree complex wavelet transform and improved 2DPCA employing SVM classifier in order to give higher coherent recognition rate. The experimental results on ORL and YALE face databases shows that the proposed method improves the performance of face recognition with respect to exiting techniques.
Whitelist malware defense for embedded control system devices

Malware protection is a necessity for any electric device in modern critical infrastructure. We must all protect our critical cyber assets with antivirus as North American Electric Reliability Corporation (NERC) CIP-007 R4 states, but more broadly, we must protect our assets from malicious code infection regardless of whether they are identified as critical assets or not. Embedded devices and traditional personnel computer devices should be protected. The Stuxnet worm demonstrated that air gaps and unplugged devices are not immune from infection. We must engineer devices and systems to protect against the impact of malware. Traditionally, this protection was accomplished by using blacklist technology, where the technology watched for known bad code and blocked it. This resulted in a race to update malware protection technology when new threats were discovered, before infection happened. With malware statistics topping 83 million pieces of code, based on the August 2014 McAfee Labs Threats Report, and growing every day, the administrative task is impossible to keep up with. This design also can put excessive burden on processors, slowing computations and communications. New malware protection technology is designed using a whitelist architecture that only allows known good code to execute on the device. This simplifies administrative overhead because new updates are not needed when new malware is released. A control system environment is built with application-specific devices that are set to accomplish one or more tasks and left alone to continue accomplishing the same tasks for many years, setting a perfect stage for whitelist malware protection technology. This paper investigates the benefits that whitelist malware protection provides at the application layer (similar to existing anti-malware technology) and explains why embedded devices need architecture-specific malware protection. The paper shows that correctly combining malware protection and embedded architecture improves the reliability and cost of ownership of the whole system. The paper also highlights the enhanced security that whitelist malware protection provides over traditional solutions and how these principles apply to computers and embedded devices. The paper shows how whitelist malware protection meets and exceeds the NERC CIP requirements in Versions 3 and 5.
Low Genetic Diversity Study on Leopard Coral Grouper Plectropomus leopardus (Perciformes: Serranidae) from Sulawesi, Indonesia JIPK (JURNAL ILMIAH PERIKANAN DAN KELAUTAN)

Bar-cheek coral trout ( P. leopardus ) is the flagship of the grouper in the live fish market in Asia. Unfortunately, the potential of the grouper is still partly produced from natural catches. Even though hybridisation activities have also started to be carried out, there still have not been many studies on the genetic diversity of these fish. The application of molecular identification has been widely applied in marine aquatic animal species, which are very likely to occur due to errors in terms of shape and colour in the morphological character. DNA information has been beneficial in efforts to the breeding program and develop grouper aquaculture activities. DNA barcoding was used for the molecular identification and haplotype analysis of P. leopardus from two locations in Gorontalo, Sulawesi, Indonesia. A total of 14 fish samples were collected from two traditional fish markets around Kwandang and Sumalata Gulf in the northern part of Gorontalo Province, Sulawesi. This study identified and found three haplotypes from both regions. Molecular identification using Cytochrome c Oxidase subunit I (COI) gene region on mitochondrial DNA. Besides Mega7 for phylogenetic reconstruction, the data analysis using DnaSP6, Arlequin Ver.3. 5.2. 2, and Network 5.0. 1.1. The first Haplotype is a mixed population between the Kwandang Gulf and the Sumalata Gulf, then the Kwandang Gulf haplotype and the Sumalata Gulf haplotype. The genetic distance between Kwandang Gulf haplotype and Sumalata Gulf haplotype is 0.003984, classified as a shallow genetic distance and needs more samples from another region to figure out leopard coral grouper around Indonesia. in Sulawesi. This condition is possible because many researchers have deposited genetic information in the GenBank database. GenBank has become central to depositing diversity from all parts of the world. Scien-tists have demonstrated their effectiveness in conduct ing DNA barcoding from freshwater fish ( Hubert et al ., 2008; Kadarusman et al ., 2012 ), marine fish ( Alcantara and Yambot, 2016; Andriyono et al ., 2020a; Bingpeng et al ., 2018; Lakra et al ., 2011; Wang et al ., 2012; Ward et al ., 2005 ), and also deep-sea fish ( Morita, 1999). Due to the mitochondrial DNA having a higher mutation rate and inheriting the maternal gene, researchers can study the evolution between species and within the same species (Waugh, 2007). This report identified the leopard coral grouper P. leopardus from two areas in Gorontalo through a molecular approach. In addition, the analysis
Design and initial validation of a wireless control system based on WSN

At present, cantilever structure used widely in civil structures will generate continuous vibration by external force due to their low damping characteristic, which leads to a serious impact on the working performance and service time. Therefore, it is very important to control the vibration of these structures. The active vibration control is the primary means of controlling the vibration with high precision and strong adaptive ability. Nowadays, there are many researches using piezoelectric materials in the structural vibration control. Piezoelectric materials are cheap, reliable and they can provide braking and sensing method harmless to the structure, therefore they have broad usage. They are used for structural vibration control in a lot of civil engineering research currently. In traditional sensor applications, information exchanges with the monitoring center or a computer system through wires. If wireless sensor networks(WSN) technology is used, cabling links is not needed, thus the cost of the whole system is greatly reduced. Based on the above advantages, a wireless control system is designed and validated through preliminary tests. The system consists of a cantilever, PVDF as sensor, signal conditioning circuit(SCM), A/D acquisition board, control arithmetic unit, D/A output board, power amplifier, piezoelectric bimorph as actuator. DSP chip is used as the control arithmetic unit and PD control algorithm is embedded in it. PVDF collects the parameters of vibration, sends them to the SCM after A/D conversion. SCM passes the data to the DSP through wireless technology, and DSP calculates and outputs the control values according to the control algorithm. The output signal is amplified by the power amplifier to drive the piezoelectric bimorph for vibration control. The structural vibration duration reduces to 1/4 of the uncontrolled case, which verifies the feasibility of the system.
A Tectono-magmatic correlation of basaltic rocks from ophiolite mélanges at the North-Eastern tip of the Sava-Vardar suture Zone, Northern Croatia, constrained by geochemistry and petrology

Ophiolite melanges of Mts. Kalnik and Ivanscica form the northern sector of the Kalnik Unit and represent the northeasternmost exposed tip of the Sava- Vardar Suture Zone. Petrological; geochemical and isotopic characteristics of extrusive rock blocks incorporated in the melanges; particularly of pillow basalt altered to spilite; in association with radiolarian cherts; allow the rocks to be separated into five distinct groups. Each group has an age-marker based on the radiolarian assemblage in the associated cherts and/or on isotope dating which; along with previously published data on the Kalnik Unit; provide detailed analysis of the approximately 80 Ma long geodynamic evolution of the Repno Oceanic Domain - a part of the Meliata-Maliak ocean system. The rock groups are: (1) Late Anisian alkali basalts [(La/Lu)cn = 5.9-7.2; eNd(T) = +2.96; Cpx-TiO2 = 3-6wt%] related to a terminal phase of intracontinental rifting; (2) enriched E-MORB-type basalts [(La/Lu)cn = 2.4-2.8; eNd(T) = +4.74; Cpx-TiO2 = 2.1-2.9wt%] and depleted E-MORB-type basalts [(La/Lu)cn ~ 1.5; eNd(T) = +5.26; Cpx- TiO2 = 1.9-2.3wt%] which reflect successive proto-oceanic crust formed at the ridge during the early Ladinian and late Ladinian; respectively; (3) middle Carnian T-MORB-type basalts [(La/Sm)cn = 0.79-0.87; eNd(T) = +6.63; Cpx-TiO2 = 1.2-2.2wt%]; representing crust from an evolved spreading center; (4) NMORB- type basalts [(La/Sm)cn = 0.67-0.87; eNd(T) = +6.58; Cpx-TiO2 = 0.6-1.9wt%] with inherited supra-subduction signature that diminish from the Late Carnian basalts [(Nb/La)n = 0.81] to the Bajocian basalts [(Nb/La)n = 1.1]; and Middle Jurassic (Bathonian? ) N-MORB-type basalts with recurrent subduction related influence [Nb/La)n = 0.72; (La/Sm)cn = 0.76; eNd(T) = +6.23]; (5) late Bathonian medium-Ti [(Nb/La)n = 0.24-0.72; eNd(T) = +6.30; Cpx-TiO2 = 0.6- 1.1wt%] to late Oxfordian low-Ti IAT-type basalts [(Nb/La)n = 0.12-0.22; eNd(T) = +6.31; Cpx-TiO2 = 0.2-0.6wt%] which reflect melts derived from a metasomatized and successively depleted mantle wedge in an extensional proto-arc setting.
