If part of the complexity is resulting from uncertainties, an efficient way for solving that is robust control. By this way, the control procedure could be simple and fast and finally, a simple controller can be designed. One kind of these mechanisms is 3-<u>R</u>RR which is a parallel mechanism and has three revolute joints. This paper aims to robust control a 3-<u>R</u>RR planner mechanism and it presents that this could be used for other mechanisms. So, a significant problem in mechanisms control could be solved.

The control of this mechanism and similar mechanisms is one that has always been the intention of the scholars. On the other hand, modeling the behavior of the system is difficult due to the large number of its parameters, and it leads to complex equations that are difficult to solve and eventually difficult to control. In this paper, a six-linkage robot has been presented that could be used in different areas such as medical robots. Using these robots needs a robust control. In this paper, the system equations are first found, and then the system conversion function is written. A new controller has been designed for this robot which could be used in other parallel robots and could be very useful. Parallel robots are so important in robotics because of their stability, so methods for control of them are important and the robust controller, especially in parallel robots, makes a sense. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3-RRS" title="3-RRS">3-RRS</a>, <a href="https://publications.waset.org/abstracts/search?q=6%20linkage" title=" 6 linkage"> 6 linkage</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20robot" title=" parallel robot"> parallel robot</a>, <a href="https://publications.waset.org/abstracts/search?q=control" title=" control"> control</a> </p> <a href="https://publications.waset.org/abstracts/100326/designing-a-robust-controller-for-a-6-linkage-robot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100326.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12823</span> Two Spherical Three Degrees of Freedom Parallel Robots 3-RCC and 3-RRS Static Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Abbasi%20Moshaii">Alireza Abbasi Moshaii</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaghayegh%20Nasiri"> Shaghayegh Nasiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Tale%20Masouleh"> Mehdi Tale Masouleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this study is static analysis of two three-degree of freedom parallel mechanisms: 3-RCC and 3-RRS. Geometry of these mechanisms is expressed and static equilibrium equations are derived for the whole chains. For these mechanisms due to the equal number of equations and unknowns, the solution is as same as 3-RCC mechanism. Mathematical software is used to solve the equations. In order to prove the results obtained from solving the equations of mechanisms, their CAD model has been simulated and their static is analysed in ADAMS software. Due to symmetrical geometry of the mechanisms, the force and external torque acting on the end-effecter have been considered asymmetric to prove the generality of the solution method. Finally, the results of both softwares, for both mechanisms are extracted and compared as graphs. The good achieved comparison between the results indicates the accuracy of the analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=robotic" title="robotic">robotic</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20analysis" title=" static analysis"> static analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=3-RCC" title=" 3-RCC"> 3-RCC</a>, <a href="https://publications.waset.org/abstracts/search?q=3-RRS" title=" 3-RRS"> 3-RRS</a> </p> <a href="https://publications.waset.org/abstracts/24128/two-spherical-three-degrees-of-freedom-parallel-robots-3-rcc-and-3-rrs-static-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24128.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12822</span> A Compact Quasi-Zero Stiffness Vibration Isolator Using Flexure-Based Spring Mechanisms Capable of Tunable Stiffness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thanh-Phong%20Dao">Thanh-Phong Dao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shyh-Chour%20Huang"> Shyh-Chour Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a quasi-zero stiffness (QZS) vibration isolator using flexure-based spring mechanisms which afford both negative and positive stiffness elements, which enable self-adjustment. The QZS property of the isolator is achieved at the equilibrium position. A nonlinear mathematical model is then developed, based on the pre-compression of the flexure-based spring mechanisms. The dynamics are further analyzed using the Harmonic Balance method. The vibration attention efficiency is illustrated using displacement transmissibility, which is then compared with the corresponding linear isolator. The effects of parameters on performance are also investigated by numerical solutions.

Unlike traditional systems using serial or parallel mechanisms for multi-DOF rotations, the HSMM is capable of implementing continuous 2-DOF rotational motions in a single joint without the intermediate transmission mechanisms. It has some advantages of compact structure, low inertia and high stiffness. However, as HSMM is a nonlinear and multivariable system, it is very complicate to realize accuracy control. Therefore, an augmented active disturbance rejection controller (ADRC) is proposed in this paper. Compared with the traditional PD control method, three compensation items, i.e., dynamics compensation term, disturbance compensation term and nonlinear error elimination term, are added into the proposed algorithm to improve the control performance. The ADRC algorithm aims at offsetting the effects of external disturbance and realizing accurate control. Euler angles are applied to describe the orientation of rotor. Lagrange equations are utilized to establish the dynamic model of the HSMM. The stability of this algorithm is validated with detailed derivation. Simulation model is formulated in Matlab/Simulink. The results show that the proposed control algorithm has better competence of trajectory tracking in the presence of uncertainties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20spherical%20motion%20mechanism" title="hydraulic spherical motion mechanism">hydraulic spherical motion mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20model" title=" dynamic model"> dynamic model</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20disturbance%20rejection%20control" title=" active disturbance rejection control"> active disturbance rejection control</a>, <a href="https://publications.waset.org/abstracts/search?q=trajectory%20tracking" title=" trajectory tracking"> trajectory tracking</a> </p> <a href="https://publications.waset.org/abstracts/126959/augmented-adrc-for-trajectory-tracking-of-a-novel-hydraulic-spherical-motion-mechanism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126959.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12819</span> The Role of Defense Mechanisms in Treatment Adherence in Type 2 Diabetes Mellitus: An Exploratory Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Marchini">F.

Materials and methods: A correlational study design was employed. Thirty-two persons with type 2 diabetes mellitus were enrolled and assessed with Defense Mechanism Inventory, Beck Depression Inventory-II, Toronto Alexithymia Scale and Self-Care Inventory-Revised. Bivariate correlation and two-step regression analyses were performed. Results: Treatment adherence negatively correlates with hetero-directed hostility (r= -.537; p < .01), whereas it is positively associated with principalization (r= .407; p < .05). These two defense mechanisms overall explain an incremental variance of 26.9% in treatment adherence (ΔF=4.189, df1=2, df2 =21, p < .05), over and above the control variables for depression and alexithymia. However, only higher hetero-directed hostility is found to be a solid predictor of a decreased treatment adherence (β=-.497, p < .05). Conclusions: Despite providing preliminary results, this pilot study highlights the original contribution of defense mechanisms in adherence to type 2 diabetes regimens. Specifically, hetero-directed hostility may relate to an unconscious process, according to which disease-related painful feelings are displaced onto care relationships with negative impacts on adherence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alexithymia" title="alexithymia">alexithymia</a>, <a href="https://publications.waset.org/abstracts/search?q=defense%20mechanisms" title=" defense mechanisms"> defense mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20adherence" title=" treatment adherence"> treatment adherence</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20diabetes%20mellitus" title=" type 2 diabetes mellitus"> type 2 diabetes mellitus</a> </p> <a href="https://publications.waset.org/abstracts/93212/the-role-of-defense-mechanisms-in-treatment-adherence-in-type-2-diabetes-mellitus-an-exploratory-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93212.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">319</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12818</span> Remote Electroacupuncture Analgesia at Contralateral LI4 Acupoint in Complete Freund's Adjuvant-Induced Inflammatory Hindpaw Pain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tong-Chien%20Wu">Tong-Chien Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching-Liang%20Hsieh"> Ching-Liang Hsieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Wen%20Lin"> Yi-Wen Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are accumulating evidences surrounding the therapeutic effect of electroacupuncture (EA). Local EA can reliably attenuate inflammatory pain in mouse with unclear mechanisms. However, the effect of EA on distal and contralateral acupoint for pain control has been rarely studied and the result was controversial. Here in our study, we found that inflammatory hindpaw pain in mouth, which was induced by injecting the complete Freund’s adjuvant (CFA) 2 days ago can be alleviated immediately after 2Hz 15mins EA treatment at contralateral forefoot acupoint LI4 through both mechanic and thermal behavior test, while sham acupoint group is not. The efficacy was observed to be more obvious after the second round of EA treatment on the following day. This analgesic effect is produced by applying EA to a site remote from the painful area. The present study provides a powerful experimental animal model that can be used for investigating the unique physiological mechanisms involved in acupuncture analgesia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=remote%20electroacupuncture" title="remote electroacupuncture">remote electroacupuncture</a>, <a href="https://publications.waset.org/abstracts/search?q=distal%20EA" title=" distal EA"> distal EA</a>, <a href="https://publications.waset.org/abstracts/search?q=pain%20control" title=" pain control"> pain control</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-inflammation" title=" anti-inflammation"> anti-inflammation</a> </p> <a href="https://publications.waset.org/abstracts/85446/remote-electroacupuncture-analgesia-at-contralateral-li4-acupoint-in-complete-freunds-adjuvant-induced-inflammatory-hindpaw-pain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85446.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">187</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12817</span> Bioactive Chemical Markers Based Strategy for Quality Control of Herbal Medicines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhenzhong%20Yang">Zhenzhong Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Herbal medicines are important supplements to chemical drugs and usually consist of a complex mixture of constituents. The current quality control strategy of herbal medicines is mainly based on chemical markers, which largely failed to owe to the markers, not reflecting the herbal medicines’ multiple mechanisms of action. Herein, a bioactive chemical markers based strategy was proposed and applied to the quality assessment and control of herbal medicines. This strategy mainly includes the comprehensive chemical characterization of herbal medicines, bioactive chemical markers identification, and related quantitative analysis methods development. As a proof-of-concept, this strategy was applied to a Panax notoginseng derived herbal medicine. The bioactive chemical markers based strategy offers a rational approach for quality assessment and control of herbal medicines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioactive%20chemical%20markers" title="bioactive chemical markers">bioactive chemical markers</a>, <a href="https://publications.waset.org/abstracts/search?q=herbal%20medicines" title=" herbal medicines"> herbal medicines</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20assessment" title=" quality assessment"> quality assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20control" title=" quality control"> quality control</a> </p> <a href="https://publications.waset.org/abstracts/128810/bioactive-chemical-markers-based-strategy-for-quality-control-of-herbal-medicines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128810.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">178</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12816</span> Reproductive Governmentality in Mexico: Production, Control and Regulation of Contraceptive Practices in a Public Hospital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Orozco">Ivan Orozco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Forced contraception constitutes part of an effort to control the life and reproductive capacity of women through public health institutions. This phenomenon has affected many Mexican women historically and still persists nowadays. The notion of reproductive governmentality refers to the mechanisms through which different historical configurations of social actors (state institutions, churches, donor agents, NGOs, etc.) use legislative controls, economic incentives, moral mandates, direct coercion, and ethical incitements, to produce, monitor and control reproductive behaviors and practices. This research focuses on the use of these mechanisms by the Mexican State to control women's contraceptive practices in a public hospital. Method: An Institutional Ethnography was carried out, with the objective of knowing women's experiences from their own perspective, as they occur in their daily lives, but at the same time, discovering the structural elements that shape the discourses that promote women's contraception, even against their will. The fieldwork consisted in an observation of the dynamics between different participants within a public hospital and the conduction of interviews with the medical and nursing staff in charge of family planning services, as well as women attending the family planning office. Results: Public health institutions in Mexico are state tools to control and regulate reproduction. There are several strategies that are used for this purpose, for example, health personnel provide insufficient or misleading information to ensure that women agree to use contraceptives; health institutions provide economic incentives to the members of the health staff who reach certain goals in terms of contraceptive placement; young women are forced to go to the family planning service, regardless of the reason they went to the clinic; health campaigns are carried out, consisting of the application of contraceptives outside the health facilities, directly in the communities of people who visit the hospital less frequently. All these mechanisms seek for women to use contraceptives, from the women’s perspective; however, the reception of these discourses is ambiguous. While, for some women, the strategies become coercive mechanisms to use contraceptives against their will, for others, they represent an opportunity to take control over their reproductive lives. Conclusion: Since 1974, the Mexican government has implemented campaigns for the promotion of family planning methods as a means to control population growth. Although it is established in several legislations that the counselling must be carried out with a gender and human rights perspective, always respecting the autonomy of people, these research testify that health personnel uses different strategies to force some women to use contraceptive methods, thereby violating their reproductive rights. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=feminist%20research" title="feminist research">feminist research</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20contraception" title=" forced contraception"> forced contraception</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20ethnography" title=" institutional ethnography"> institutional ethnography</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive.%20governmentality" title=" reproductive. governmentality"> reproductive. governmentality</a> </p> <a href="https://publications.waset.org/abstracts/124068/reproductive-governmentality-in-mexico-production-control-and-regulation-of-contraceptive-practices-in-a-public-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124068.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12815</span> Predicting the Relationship Between Childhood Trauma on the Formation of Defense Mechanisms with the Mediating Role of Object Relations in Traders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmadreza%20Jabalameli">Ahmadreza Jabalameli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ebrahimpour%20Borujeni"> Mohammad Ebrahimpour Borujeni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to psychodynamic theories, the major personality structure of individuals is formed in the first years of life.

The present study deals with the relationship between childhood trauma on the formation of defense mechanisms and the role of object relations. The present descriptive study is a correlation with structural equation modeling (SEM). Sample selection is available and consists of 200 knowledgeable traders in Jabalameli Information Technology Company. The results indicate that the experience of childhood trauma with a demographic moderating effect, through the mediating role of object relations can lead to vulnerability to ego reality functionality and immature and psychically disturbed defense mechanisms. In this regard, there is a significant negative relationship between childhood trauma and object relations with mature defense mechanisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=childhood%20trauma" title="childhood trauma">childhood trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=defense%20mechanisms" title=" defense mechanisms"> defense mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20relations" title=" object relations"> object relations</a>, <a href="https://publications.waset.org/abstracts/search?q=trade" title=" trade"> trade</a> </p> <a href="https://publications.waset.org/abstracts/148276/predicting-the-relationship-between-childhood-trauma-on-the-formation-of-defense-mechanisms-with-the-mediating-role-of-object-relations-in-traders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148276.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">132</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12814</span> Mechanisms of Action in Mindfulness-Based Cognitive Therapy (MBCT) and Mindfulness-Based Stress Reduction (MBSR) in People with Physical and/or Psychological Conditions: A Systematic Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Modi%20Alsubaie">Modi Alsubaie</a>, <a href="https://publications.waset.org/abstracts/search?q=Willem%20Kuyken"> Willem Kuyken</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebecca%20Abbott"> Rebecca Abbott</a>, <a href="https://publications.waset.org/abstracts/search?q=Barnaby%20Dunn"> Barnaby Dunn</a>, <a href="https://publications.waset.org/abstracts/search?q=Chris%20Dickens"> Chris Dickens</a>, <a href="https://publications.waset.org/abstracts/search?q=Tina%20Keil"> Tina Keil</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Henley"> William Henley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Recently, there has been an increased interest in studying the effects of mindfulness-based interventions for people with psychological and physical problems. However, the mechanisms of action in these interventions that lead to beneficial physical and psychological outcomes have yet to be clearly identified. Purpose: The aim of this paper is to review, systematically, the evidence to date on the mechanisms of action in mindfulness interventions in populations with physical and/or psychological conditions. Method: Searches of seven databases (PsycINFO, Medline (Ovid), Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, AMED, ClinicalTrials.gov) were undertaken in June 2014 and July 2015. We evaluated to what extent the studies we identified met the criteria suggested by Kazdin for establishing mechanisms of action within a psychological treatment (2007, 2009). Results: We identified four trials examining mechanisms of mindfulness interventions in those with comorbid psychological and physical health problems and 14 in those with psychological conditions. These studies examined a diverse range of potential mechanisms, including mindfulness and rumination. Of these candidate mechanisms, the most consistent finding was that greater self-reported change in mindfulness mediated superior clinical outcomes. However, very few studies fully met the Kazdin criteria for examining treatment mechanisms. Conclusion: There was evidence that global changes in mindfulness are linked to better outcomes. This evidence pertained more to interventions targeting psychological rather than physical health conditions. While there is promising evidence that MBCT/MBSR intervention effects are mediated by hypothesised mechanisms, there is a lack of methodological rigour in the field of testing mechanisms of action for both MBCT and MBSR, which precludes definitive conclusions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MBCT" title="MBCT">MBCT</a>, <a href="https://publications.waset.org/abstracts/search?q=MBSR" title=" MBSR"> MBSR</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanisms" title=" mechanisms"> mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20conditions" title=" physical conditions"> physical conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20conditions" title=" psychological conditions"> psychological conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20review" title=" systematic review "> systematic review </a> </p> <a href="https://publications.waset.org/abstracts/72947/mechanisms-of-action-in-mindfulness-based-cognitive-therapy-mbct-and-mindfulness-based-stress-reduction-mbsr-in-people-with-physical-andor-psychological-conditions-a-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72947.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">331</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12813</span> A Review of Self-Healing Concrete and Various Methods of Its Scientific Implementation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Davoud%20Beheshtizadeh">Davoud Beheshtizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Davood%20Jafari"> Davood Jafari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concrete, with its special properties and advantages, has caused it to be widely and increasingly used in construction industry, especially in infrastructures of the country. On the other hand, some defects of concrete and, most importantly, micro-cracks in the concrete after setting have caused the cost of repair and maintenance of infrastructure; therefore, self-healing concretes have been of attention in other countries in the recent years. These concretes have been repaired with general mechanisms such as physical, chemical, biological and combined mechanisms, each of which has different subsets and methods of execution and operation. Also, some of these types of mechanisms are of high importance, which has led to a special production method, and as this subject is new in Iran, this knowledge is almost unknown or at least some part of it has not been considered at all.

This approach, however, does not differentiate between amplitude and frequency modulations, AM and FM, respectfully. It was experimentally shown that both modulations could be present in the spectrum, yet each modulation may be associated with different physical mechanisms. AM mechanisms are quite well understood and widely covered in the literature. This paper is a first attempt to explain the generation mechanisms of FM and its correlation with the flaw properties. Here we proposed two possible mechanisms leading to FM modulation based on nonlinear local defect resonance and dynamic acousto-elastic models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20testing" title="non-destructive testing">non-destructive testing</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20acoustics" title=" nonlinear acoustics"> nonlinear acoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20health%20monitoring" title=" structural health monitoring"> structural health monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=acousto-elasticity" title=" acousto-elasticity"> acousto-elasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20defect%20resonance" title=" local defect resonance"> local defect resonance</a> </p> <a href="https://publications.waset.org/abstracts/149507/frequency-modulation-in-vibro-acoustic-modulation-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149507.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12811</span> Survey of Access Controls in Cloud Computing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monirah%20Alkathiry">Monirah Alkathiry</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Aljarwan"> Hanan Aljarwan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cloud computing is one of the most significant technologies that the world deals with, in different sectors with different purposes and capabilities. The cloud faces various challenges in securing data from unauthorized access or modification. Consequently, security risks and levels have greatly increased. Therefore, cloud service providers (CSPs) and users need secure mechanisms that ensure that data are kept secret and safe from any disclosures or exploits. For this reason, CSPs need a number of techniques and technologies to manage and secure access to the cloud services to achieve security goals, such as confidentiality, integrity, identity access management (IAM), etc. Therefore, this paper will review and explore various access controls implemented in a cloud environment that achieve different security purposes. The methodology followed in this survey was conducting an assessment, evaluation, and comparison between those access controls mechanisms and technologies based on different factors, such as the security goals it achieves, usability, and cost-effectiveness. This assessment resulted in the fact that the technology used in an access control affects the security goals it achieves as well as there is no one access control method that achieves all security goals. Consequently, such a comparison would help decision-makers to choose properly the access controls that meet their requirements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=access%20controls" title="access controls">access controls</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=confidentiality" title=" confidentiality"> confidentiality</a>, <a href="https://publications.waset.org/abstracts/search?q=identity%20and%20access%20management" title=" identity and access management"> identity and access management</a> </p> <a href="https://publications.waset.org/abstracts/125048/survey-of-access-controls-in-cloud-computing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125048.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12810</span> A Comprehensive Approach to Mitigate Return-Oriented Programming Attacks: Combining Operating System Protection Mechanisms and Hardware-Assisted Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Xingnan">Zhang Xingnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Huang%20Jingjia"> Huang Jingjia</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Yue"> Feng Yue</a>, <a href="https://publications.waset.org/abstracts/search?q=Burra%20Venkata%20Durga%20Kumar"> Burra Venkata Durga Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a comprehensive approach to mitigate ROP (Return-Oriented Programming) attacks by combining internal operating system protection mechanisms and hardware-assisted techniques.

Depending on the extraction systems, these new solvents show better efficiency than the conventional ones. Although some assumptions based on ions exchanges have been proposed in the literature, these properties are not predictable because the involved mechanisms are still poorly understood. It is well established that the mechanisms underlying solvent extraction processes are based not only on the molecular chelation of the extractant molecules but also on their ability to form supra-molecular aggregates due to their amphiphilic nature. It is therefore essential to evaluate how IL affects the aggregation properties of the extractant molecules. Our aim is to evaluate the influence of IL structure and polarity on solvent extraction mechanisms, by looking at the aggregation of the extractant molecules in IL. We compare extractant systems that are well characterized in common solvents and show thanks to SAXS and SANS measurements, that in the absence of IL ion exchange mechanisms, extraction properties are related to aggregation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solvent%20extraction%20in%20Ionic%20liquid" title="solvent extraction in Ionic liquid">solvent extraction in Ionic liquid</a>, <a href="https://publications.waset.org/abstracts/search?q=aggregation" title=" aggregation"> aggregation</a>, <a href="https://publications.waset.org/abstracts/search?q=Ionic%20liquids%20structure" title=" Ionic liquids structure"> Ionic liquids structure</a>, <a href="https://publications.waset.org/abstracts/search?q=SAXS" title=" SAXS"> SAXS</a>, <a href="https://publications.waset.org/abstracts/search?q=SANS" title=" SANS"> SANS</a> </p> <a href="https://publications.waset.org/abstracts/107612/solvent-extraction-in-ionic-liquids-structuration-and-aggregation-effects-on-extraction-mechanisms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107612.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12807</span> Effect of Carbon Amount of Dual-Phase Steels on Deformation Behavior Using Acoustic Emission</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Khamedi">Ramin Khamedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Isa%20Ahmadi"> Isa Ahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study acoustic emission (AE) signals obtained during deformation and fracture of two types of ferrite-martensite dual phase steels (DPS) specimens have been analyzed in frequency domain. For this reason two low carbon steels with various amounts of carbon were chosen, and intercritically heat treated. In the introduced method, identifying the mechanisms of failure in the various phases of DPS is done. For this aim, AE monitoring has been used during tensile test of several DPS with various volume fraction of the martensite (VM) and attempted to relate the AE signals and failure mechanisms in these steels. Different signals, which referred to 2-3 micro-mechanisms of failure due to amount of carbon and also VM have been seen. By Fast Fourier Transformation (FFT) of signals in distinct locations, an excellent relationship between peak frequencies in these areas and micro-mechanisms of failure were seen. The results were verified by microscopic observations (SEM). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20emission" title="acoustic emission">acoustic emission</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20phase%20steels" title=" dual phase steels"> dual phase steels</a>, <a href="https://publications.waset.org/abstracts/search?q=deformation" title=" deformation"> deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=failure" title=" failure"> failure</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a> </p> <a href="https://publications.waset.org/abstracts/10129/effect-of-carbon-amount-of-dual-phase-steels-on-deformation-behavior-using-acoustic-emission" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10129.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">403</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12806</span> Moderating Effects of Family Ownership on the Relationship between Corporate Governance Mechanisms and Financial Performance of Publicly Listed Companies in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ndagi%20Salihu">Ndagi Salihu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Corporate governance mechanisms are the control measures for ensuring that all the interests groups are equally represented and management are working towards wealth creation in the interest of all. Therefore, there are many empirical studies during the last three decades on corporate governance and firm performance. However, little is known about the effects of family ownership on the relationship between corporate governance and firm performance, especially in the developing economy like Nigeria. This limit our understanding of the unique governance dynamics of family ownership with regards firm performance. This study examined the impact of family ownership on the relationship between governance mechanisms and financial performance of publicly listed companies in Nigeria. The study adopted quantitative research methodology using correlational ex-post factor design and secondary data from annual reports and accounts of a sample of 23 listed companies for a period of 5 years (2014-2018). The explanatory variables are the board size, board composition, board financial expertise, and board audit committee attributes. Financial performance is proxy by Return on Assets (ROA) and Return on Equity (ROE). Multiple panel regression technique of data analysis was employed in the analysis, and the study found that family ownership has a significant positive effect on the relationships between corporate governance mechanisms and financial performance of publicly listed firms in Nigeria. This finding is the same for both the ROA and ROE. However, the findings indicate that board size, board financial expertise, and board audit committee attributes have a significant positive impact on the ROA and ROE of the sample firms after the moderation. Moreover, board composition has significant positive effect on financial performance of the sample listed firms in terms of ROA and ROE. The study concludes that the use of family ownership in the control of firms in Nigeria could improve performance by reducing the opportunistic actions managers as well as agency problems. The study recommends that publicly listed companies in Nigeria should allow significant family ownership of equities and participation in management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=profitability" title="profitability">profitability</a>, <a href="https://publications.waset.org/abstracts/search?q=board%20characteristics" title=" board characteristics"> board characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=agency%20theory" title=" agency theory"> agency theory</a>, <a href="https://publications.waset.org/abstracts/search?q=stakeholders" title=" stakeholders"> stakeholders</a> </p> <a href="https://publications.waset.org/abstracts/114637/moderating-effects-of-family-ownership-on-the-relationship-between-corporate-governance-mechanisms-and-financial-performance-of-publicly-listed-companies-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114637.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12805</span> Balance Control Mechanisms in Individuals With Multiple Sclerosis in Virtual Reality Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Badriah%20Alayidi">Badriah Alayidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Emad%20Alyahya"> Emad Alyahya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Most people with Multiple Sclerosis (MS) report worsening balance as the condition progresses. Poor balance control is also well known to be a significant risk factor for both falling and fear of falling. The increased risk of falls with disease progression thus makes balance control an essential target of gait rehabilitation amongst people with MS. Intervention programs have developed various methods to improve balance control, and accumulating evidence suggests that exercise programs may help people with MS improve their balance. Among these methods, virtual reality (VR) is growing in popularity as a balance-training technique owing to its potential benefits, including better compliance and greater user happiness. However, it is not clear if a VR environment will induce different balance control mechanisms in MS as compared to healthy individuals or traditional environments. Therefore, this study aims to examine how individuals with MS control their balance in a VR setting. Methodology: The proposed study takes an empirical approach to estimate and determine the role of balance response in persons with MS using a VR environment. It will use primary data collected through patient observations, physiological and biomechanical evaluation of balance, and data analysis. Results: The preliminary systematic review and meta-analysis indicated that there was variability in terms of the outcome assessing balance response in people with MS. The preliminary results of these assessments have the potential to provide essential indicators of the progression of MS and contribute to the individualization of treatment and evaluation of the interventions’ effectiveness. The literature describes patients who have had the opportunity to experiment in VR settings and then used what they have learned in the real world, suggesting that this VR setting could be more appealing than conditional settings. The findings of the proposed study will be beneficial in estimating and determining the effect of VR on balance control in persons with MS. In previous studies, VR was shown to be an interesting approach to neurological rehabilitation, but more data are needed to support this approach in MS. Conclusions: The proposed study enables an assessment of balance and evaluations of a variety of physiological implications related to neural activity as well as biomechanical implications related to movement analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiple%20sclerosis" title="multiple sclerosis">multiple sclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title=" virtual reality"> virtual reality</a>, <a href="https://publications.waset.org/abstracts/search?q=postural%20control" title=" postural control"> postural control</a>, <a href="https://publications.waset.org/abstracts/search?q=balance" title=" balance"> balance</a> </p> <a href="https://publications.waset.org/abstracts/168180/balance-control-mechanisms-in-individuals-with-multiple-sclerosis-in-virtual-reality-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168180.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12804</span> Defense Mechanism Maturity and the Severity of Mood Disorder Symptoms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maja%20Pand%C5%BEa">Maja Pandža</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjin%20Lovri%C4%87"> Sanjin Lovrić</a>, <a href="https://publications.waset.org/abstracts/search?q=Iva%20%C4%8Colak"> Iva Čolak</a>, <a href="https://publications.waset.org/abstracts/search?q=Josipa%20Mandari%C4%87"> Josipa Mandarić</a>, <a href="https://publications.waset.org/abstracts/search?q=Miro%20Klari%C4%87"> Miro Klarić</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study explores the role of symptoms related to mood disorders salience on different types of defense mechanisms (mature, neurotic, immature) predominance.

The sample was additionally divided into four groups, given the level of symptoms experienced: 1. minimal, 2. mild, 3. moderate, 4. severe depression/anxiety. Participants with minimal anxiety and depression symptoms use mature defense mechanisms more often than other three groups. Immature mechanisms are most commonly used by the group with severe depression/anxiety levels in comparison with other groups.

All signs and symptoms of MS are the results of confliction and mismatch among neural signal inputs. It is known that no singular remedy works for everybody, and electroacupuncture (EA) is one of the popular alternative therapies used for MS. Our study utilized a mouse model in order to exclude any psychological factors of MS and EA. Mice lack an emetic reflex. Therefore pica behavior, which is a normal consumption of non-nutritive substances, was found to measure the response of MS in mice. In the laboratory, Kaolin was used as a non-nutrient food substance instead of natural substances lacking nutritional value such as wood, cloth, charcoal, soil or grass. It was hypothesized that EA treatment could reduce the symptoms of MS through the TRPV1 pathways. The results of pica behavior showed a significantly increased intake of kaolin in the MS group throughout the experiment period. Moreover, the Kaolin intake of the EA group decreased to the average baseline of the control group. There was no recorded difference in the food and water intake of each group. The results indicated an increase of the TRPV1, pERK, pJNK and pmTOR protein levels in the thalamus after MS stimulation, and a significant decrease in the EA group compared with that of the control group. These findings suggest that TRPV1 pathways are associated in MS mechanisms and can be reduced by EA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electroacupuncture" title="electroacupuncture">electroacupuncture</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20sickness" title=" motion sickness"> motion sickness</a>, <a href="https://publications.waset.org/abstracts/search?q=Thalamus" title=" Thalamus"> Thalamus</a>, <a href="https://publications.waset.org/abstracts/search?q=TRPV1" title=" TRPV1"> TRPV1</a> </p> <a href="https://publications.waset.org/abstracts/61747/the-effect-and-mechanisms-of-electroacupuncture-on-motion-sickness-in-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61747.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">253</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12801</span> A Review of Lexical Retrieval Intervention in Primary Progressive Aphasia and Alzheimer's Disease: Mechanisms of Change, Cognition, and Generalisation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashleigh%20Beales">Ashleigh Beales</a>, <a href="https://publications.waset.org/abstracts/search?q=Anne%20Whitworth"> Anne Whitworth</a>, <a href="https://publications.waset.org/abstracts/search?q=Jade%20Cartwright"> Jade Cartwright</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: While significant benefits of lexical retrieval intervention are evident within the Primary Progressive Aphasia (PPA) and Alzheimer’s disease (AD) literature, an understanding of the mechanisms that underlie change or improvement is limited. Change mechanisms have been explored in the non-progressive post-stroke literature that may offer insight into how interventions affect change with progressive language disorders. The potential influences of cognitive factors may also play a role here, interacting with the aims of intervention. Exploring how such processes have been applied is likely to grow our understanding of how interventions have, or have not, been effective, and how and why generalisation is likely, or not, to occur. Aims: This review of the literature aimed to (1) investigate the proposed mechanisms of change which underpin lexical interventions, mapping the PPA and AD lexical retrieval literature to theoretical accounts of mechanisms that underlie change within the broader intervention literature, (2) identify whether and which nonlinguistic cognitive functions have been engaged in intervention with these populations and any proposed influence, and (3) explore evidence of linguistic generalisation, with particular reference to change mechanisms employed in interventions. Main contribution: A search of Medline, PsycINFO, and CINAHL identified 36 articles that reported data for individuals with PPA or AD following lexical retrieval intervention. A review of the mechanisms of change identified 10 studies that used stimulation, 21 studies utilised relearning, three studies drew on reorganisation, and two studies used cognitive-relay. Significant treatment gains, predominantly based on linguistic performance measures, were reported for all client groups for each of the proposed mechanisms. Reorganisation and cognitive-relay change mechanisms were only targeted in PPA. Eighteen studies incorporated nonlinguistic cognitive functions in intervention; these were limited to autobiographical memory (16 studies), episodic memory (three studies), or both (one study). Linguistic generalisation outcomes were inconsistently reported in PPA and AD studies. Conclusion: This review highlights that individuals with PPA and AD may benefit from lexical retrieval intervention, irrespective of the mechanism of change. Thorough application of a theory of intervention is required to gain a greater understanding of the change mechanisms, as well as the interplay of nonlinguistic cognitive functions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alzheimer%27s%20disease" title="Alzheimer's disease">Alzheimer's disease</a>, <a href="https://publications.waset.org/abstracts/search?q=lexical%20retrieval" title=" lexical retrieval"> lexical retrieval</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanisms%20of%20change" title=" mechanisms of change"> mechanisms of change</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20progressive%20aphasia" title=" primary progressive aphasia"> primary progressive aphasia</a> </p> <a href="https://publications.waset.org/abstracts/77439/a-review-of-lexical-retrieval-intervention-in-primary-progressive-aphasia-and-alzheimers-disease-mechanisms-of-change-cognition-and-generalisation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77439.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12800</span> Multi-omics Integrative Analysis with Genome-Scale Metabolic Model Simulation Reveals Reaction Essentiality data in Human Astrocytes Under the Lipotoxic Effect of Palmitic Acid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Janneth%20Gonzalez">Janneth Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Andres%20Pinzon%20Velasco"> Andres Pinzon Velasco</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Angarita"> Maria Angarita</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Mendoza"> Nicolas Mendoza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Astrocytes play an important role in various processes in the brain, including pathological conditions such as neurodegenerative diseases. Recent studies have shown that the increase in saturated fatty acids such as palmitic acid (PA) triggers pro-inflammatory pathways in the brain. The use of synthetic neurosteroids such as tibolone has demonstrated neuro-protective mechanisms. However, there are few studies on the neuro-protective mechanisms of tibolone, especially at the systemic (omic) level. In this study, we performed the integration of multi-omic data (transcriptome and proteome) into a human astrocyte genomic scale metabolic model to study the astrocytic response during palmitate treatment. We evaluated metabolic fluxes in three scenarios (healthy, induced inflammation by PA, and tibolone treatment under PA inflammation). We also use control theory to identify those reactions that control the astrocytic system. Our results suggest that PA generates a modulation of central and secondary metabolism, showing a change in energy source use through inhibition of folate cycle and fatty acid β-oxidation and upregulation of ketone bodies formation.We found 25 metabolic switches under PA-mediated cellular regulation, 9 of which were critical only in the inflammatory scenario but not in the protective tibolone one. Within these reactions, inhibitory, total, and directional coupling profiles were key findings, playing a fundamental role in the (de)regulation in metabolic pathways that increase neurotoxicity and represent potential treatment targets. Finally, this study framework facilitates the understanding of metabolic regulation strategies, andit can be used for in silico exploring the mechanisms of astrocytic cell regulation, directing a more complex future experimental work in neurodegenerative diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=astrocytes" title="astrocytes">astrocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20integration" title=" data integration"> data integration</a>, <a href="https://publications.waset.org/abstracts/search?q=palmitic%20acid" title=" palmitic acid"> palmitic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20model" title=" computational model"> computational model</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-omics" title=" multi-omics"> multi-omics</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20theory" title=" control theory"> control theory</a> </p> <a href="https://publications.waset.org/abstracts/147627/multi-omics-integrative-analysis-with-genome-scale-metabolic-model-simulation-reveals-reaction-essentiality-data-in-human-astrocytes-under-the-lipotoxic-effect-of-palmitic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147627.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12799</span> Comparative Study Performance of the Induction Motor between SMC and NLC Modes Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Oukaci">A.

With increasing automatic loom speeds, the dynamic loads on their separate mechanisms and moving joints sharply increase. Dynamic research allows us to determine the weakest mechanisms of the automatic loom. The modern automatic loom consists of a large number of structurally different mechanisms. These are cam, lever, gear, friction and combined cyclic mechanisms. The modern automatic loom contains various mechatronic devices: A device for the automatic removal of faulty weft, electromechanical drive warp yarns, electronic controllers, servos, etc. In the paper, we consider the multibody dynamic model of the automatic loom on the software complex SimulationX. SimulationX is multidisciplinary software for modeling complex physical and technical facilities and systems.

Magnetic levitation, a crucial technology in diverse industries, depends on meticulous control mechanisms for stability and performance. The study seeks to compare these two control strategies to ascertain their efficacy in practical applications. The paper explores the theoretical foundations of the controllers, presents an experimental methodology emphasizing setup and installation, and examines the results about stability, response time, and susceptibility to disturbances. By interpreting and discussing the findings, the research provides valuable perspectives on the practical ramifications of utilizing Two-Position and Tuned PID controllers in magnetic levitation systems. The conclusion encapsulates significant outcomes and proposes avenues for future research, thereby contributing to the progress of control strategies in magnetic levitation technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arduino" title="arduino">arduino</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative%20analysis" title=" comparative analysis"> comparative analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20levitation" title=" magnetic levitation"> magnetic levitation</a>, <a href="https://publications.waset.org/abstracts/search?q=tuned%20PID%20controller" title=" tuned PID controller"> tuned PID controller</a>, <a href="https://publications.waset.org/abstracts/search?q=two-position%20controller" title=" two-position controller"> two-position controller</a> </p> <a href="https://publications.waset.org/abstracts/182331/magnetic-levitation-control-a-comparative-analysis-of-two-position-and-tuned-pid-methods-using-arduino-microcontrollers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182331.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12796</span> Mechanical Properties of Nanocomposites Cobalt Matrix with Nano SiC Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dhuha%20Albusalih">Dhuha Albusalih</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Weston"> David Weston</a>, <a href="https://publications.waset.org/abstracts/search?q=Simon%20Gill"> Simon Gill</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanocomposites Co-SiC with well dispersed nanoparticles and Co nano grain size has produced using Pulse Reverse Plating (PRP) and using anionic surfactant. Different particle contents of nanocomposites were produced by altering the plating parameters. The method allows great control over the level of nanoparticles in the coating, without changing bath chemistry. Examination by Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDX), TEM and X-Ray Diffraction (XRD) analysis was performed to characterize and study the strengthening mechanisms of these nanocomposites. The primary strengthening mechanisms were shown to be grain refinement and dispersion strengthening. Tribological performances of the produced electroplated nanocomposite Co-SiC coatings were examined. Results showed that the coating with the higher volume fraction (vol. %) of SiC and the smallest grain size has the higher hardness and low wear rate. <p class="card-text"><strong>Keywords:</strong>
