A genetic algorithm approach for solving fuzzy linear and quadratic equations

Iin this paper a genetic algorithms approach for solving the linear and quadratic fuzzy equations (Ax) over tilde = (B) over tilde and (Ax) over tilde (2) + (Bx) over tilde = (C) over tilde, where (A) over tilde, and (B) over tilde, (C) over tilde and (x) over tilde are fuzzy numbers is proposed by genetic algorithms. Our genetic based method initially starts with a set of random fuzzy solutions. Then in each generation of genetic algorithms, the solution candidates converge more to better fuzzy solution (x) over tilde (b). in this proposed method the final reached (x) over tilde (b) is not only restricted to fuzzy triangular and it can be fuzzy number.
A comparison of sensorless speed estimation for a doubly fed induction machine

Controlled doubly fed induction motors without mechanical sensors give a low cost algorithms and a higher reliability. Three representative approaches are considered in this paper for speed estimation: MRAS estimation, Kalman filter and the injection of a high frequency stator voltage. The methods are compared in term of their sensitivity to electrical and mechanical parameters variation and their speed tracking capability
Achieving Clinical Judgment of Nursing Students through Simulation: A Quasi-experimental Study

Objective: Clinical Judgment is an inference regarding patienti¯s needs, health problems, and assertion whether or not to take action, utilize or amend universal approach or create new ones as necessary based on the patienti¯s response. This research aims to investigate the effect of simulation on the clinical judgment of Saudi nursing students utilizing Lasateri¯s Clinical Judgment Rubric (LCJR). It also aims to determine the association of gender to the participantsi¯ clinical judgment as to components noticing, interpreting, responding and reflecting. Methods: This research utilized a quasi-experimental, single group pretest posttest approach. The study was conducted in the College of Nursing at the University of Hail, Saudi Arabia. A total of 100 Saudi nursing students participated in the study (83% response rate). The participants were currently enrolled in a Medical Surgical Nursing course during the first semester of the academic year 2017-2018. Statistical Package for the Social Sciences (SPSS) program was utilized to calculate the weighted mean, standard deviation, repeated measures ANOVA, and Bonferroni test as statistical treatments. The participants underwent simulation of various patient scenarios in two separate points in time (pre-clinical training and post-clinical training) and were evaluated using the LCJR. Results: Simulation significantly has an effect in the clinical judgment of Saudi nursing students (P=0.026). Saudi nursing studentsi¯ clinical judgment depicted heightened competency in the dimensions of Responding (p=0.006) and Reflecting (p=0.005) of the LCJR. Conclusion: Simulation is an effective teaching strategy in developing clinical judgment in Saudi nursing students. Furthermore, the LCJR can be recommended for use as an assessment tool. The results of the study can be utilized by the different nursing colleges across Saudi Arabia to develop simulation programs as an adjunct in nursing education and to consider the use of the LCJR in determining the clinical judgment of nursing students.
String field theory and brane superpotentials

I discuss tree-level amplitudes in cubic topological string field theory, showing that a certain family of gauge conditions leads to an A∞ algebra of tree-level string products which define a potential describing the dynamics of physical states. Upon using results of modern deformation theory, I show that the string moduli space admits two equivalent descriptions, one given in standard Maurer-Cartan fashion and another given in terms of a ‘homotopy Maurer-Cartan problem’, which describes the critical set of the potential. By applying this construction to the topological A and B models, I obtain an intrinsic formulation of ‘D-brane superpotentials’ in terms of string field theory data. This gives a prescription for computing such quantities to all orders, and proves the equivalence of this formulation with the fundamental description in terms of string field moduli. In particular, it clarifies the relation between the Chern-Simons/holomorphic Chern-Simons actions and the superpotential for A/B-type branes.
Feasibility and Fit of a Mental Health Promotion Program for LGBTQ+ Youth

This study evaluated the feasibility and fit of a mental health promotion and violence prevention program adapted for LGBTQ+ youth (ages 14-18). The pilot program included 16 30-minute sessions and was implemented in 8 gender and sexuality alliances (GSAs) and one community youth group setting. Extensive feedback was collected from 11 facilitators via session tracking sheets, ongoing email communication, an implementation survey, and a focus group; and from 7 youth who participated in a variety of feedback activities during a 2-day post-program workshop. Results indicated a strong interest in formalized programming, challenges related to its delivery in GSAs, and significant issues with its content. Facilitators and youth advocated for the program to be more affirmative, include youth-centered notions of identities and expressions, be trauma-informed, include a wider range of relationships, and adopt a youth-led approach.
Parallel Projection Based Self Localization Method for Mobile Navigation Applications

In navigation application of mobile robot, position is estimated based on odometry and the measurement obtained by peripheral devices such as ultra-sonar, range finder, and visual sensor. Odometry is usually unreliable due to the internal factor of encoder device and the external factor of slippage. These kinds of errors accumulated in navigation continuously affect the estimation accuracy (Borenstein & Feng, 1996b; Martinelli et al., 2007). Range finder and sonar are often used in navigation (Borenstein et al., 1996a; Borenstein et al., 1997; Groβmann & Poli, 2001; Demirli & Molhim, 2004). However such measurement is not reliable in highly-dynamic environments where radar or sonar beams can be frequently blocked or confused by moving objects such as people. They are not applicable to localization in large area either because of their limited range. Also, passive sensor requires active landmarks such as beacon, which requires modification of environment and is not practical especially in an outdoor environment. Moreover, interference among several mobile sensors causes inability to properly localize their locations. Visual-information-based self-localization has advantages over above methods in two-folds. First, it does not require active landmarks (i.e., reference objects) such as beacon and also natural objects can serve as landmarks. The other advantage is that it is more effective and reliable in dynamic environment as the sensible range is not limited by the line-of-sight. These advantages have fostered much effort in research community of navigation application (Jang et al., 2002; Hayet et al., 2007; Se et al., 2002). Reference objects can be either artificial or natural objects (Betke & Gurvits, 1997; Briggs et al., 2000; Thrun, 1998; Dao et al., 2004). We assume that reference objects can be uniquely identified by a mobile robot. The global coordinates of landmarks or reference objects are known to mobile robot. There have been extensive researches about robot localization with known reference objects. The conventional self localization algorithms use the bearings of the landmarks relative to each other. This is called “visual angle” formed by the rays from a mobile robot to each reference point (Sutherland & Thompson, 1993). The location of a mobile robot is estimated by finding the intersection point of the circles passing the 7
An Approach to Optimize Query Using Rank Aware Scoring Function

Information retrieving and storing are the basic tasks of the relational database. Query optimization is used for accessing database in an efficient manner, analyzing and choosing an optimized plan is a complex process. Today's end-users are more interested in specific results rather than getting response in short time. Ranking queries (or top-k queries) are support for accessing specific results based on user's demand. Efficient execution of top-k queries is becoming a major challenge for relational database. Ranking queries produce results that are ordered on some ranking attribute. This paper presents a scoring function based rank query optimization methodology where scoring function decide preference over conduction as per user demand and shows the result of both query without ranking and ranked query, the result of ranked query is better than without ranked query.
Concurrent Constraint Programming : Calculi , Languages and Emerging Applications

Process calculi treat concurrent processes much like the λ-calculus treat computable functions. They provide a language in which the structure of terms represents the structure of processes together with an operational semantics to represent computational steps. Concurrent Constraint Programming (CCP) is a process calculus which combines the traditional operational view of process calculi with a declarative one based upon logic. This combination allows CCP to benefit from the large body of techniques of both process calculi and logic. This paper presents a (non-complete) survey of CCP based process calculi. We also show the applicability of the CCP model summarizing the main application of these calculi in different scenarios: timed and reactive systems, biological systems, music interaction and analysis of security protocols
ELIMÄKI locus is required for mechanosensing and proprioception in birch trees

The remarkable vertical and radial growth observed in tree species, encompasses a major physical challenge for wood forming tissues. To compensate with increasing size and weight, cambium-derived radial growth increases the stem width, thereby supporting the aerial body of trees. This feedback appears to be part of a so-called “proprioception” (1, 2) mechanism that controls plant size and biomass allocation. Yet, how trees experience or respond to mechanical stress derived from their own vertical loading, remains unknown. Here, we combined two strategies to dissect the proprioceptive response in birch. First, we show that in response to physical loading, trees promote radial growth with different magnitudes along the stem. Next, we identified a mutant cultivar (B. pubescens cv. Elimäki) in which the main stem shows normal vertical development, but collapses after three months. By inducing precocious flowering, we generated a backcrossed population (BC1) by producing two generations in 4 years. In his scheme, we uncovered a recessive trait (eki) that segregates and genetically maps with a Mendelian monogenic pattern. Unlike WT, eki is resistant to vertical mechanical stimulation. However, eki responds normally to the gravitropic stimulus by making tension wood. Before the collapse, cell size in eki is compromised resulting in radial growth defects, depending on stem height. Cell walls of developing xylem and phloem tissues have delayed differentiation in eki, and its tissues are softer compared to WT as indicated by atomic force microscopy (AFM). The transcriptomic profile of eki highlighted the overlap with that of the Arabidopsis response to touch. Taken together, our results suggest that the mechanical environment and cell wall properties of developing woody tissues, can significantly affect the growth responses to vertical loading thereby compromising their proprioceptive capacity. Additionally, we introduce a fast forward genetics strategy to dissect complex phenotypes in trees.
The tales of two geckos: does dispersal prevent extinction in recently fragmented populations?

Although habitat loss and fragmentation threaten species throughout the world and are a major threat to biodiversity, it is apparent that some species are at greater risk of extinction in fragmented landscapes than others. Identification of these species and the characteristics that make them sensitive to habitat fragmentation has important implications for conservation management. Here, we present a comparative study of the population genetic structure of two arboreal gecko species (Oedura reticulata and Gehyra variegata) in fragmented and continuous woodlands. The species differ in their level of persistence in remnant vegetation patches (the former exhibiting a higher extinction rate than the latter). Previous demographic and modelling studies of these two species have suggested that their difference in persistence levels may be due, in part, to differences in dispersal abilities with G. variegata expected to have higher dispersal rates than O. reticulata. We tested this hypothesis and genotyped a total of 345 O. reticulata from 12 sites and 353 G. variegata from 13 sites at nine microsatellite loci. We showed that O. reticulata exhibits elevated levels of structure (FST = 0.102 vs. 0.044), lower levels of genetic diversity (HE = 0.79 vs. 0.88), and fewer misassignments (20% vs. 30%) than similarly fragmented populations of G. variegata, while all these parameters were fairly similar for the two species in the continuous forest populations (FST = 0.003 vs. 0.004, HE = 0.89 vs. 0.89, misassignments: 58% vs. 53%, respectively). For both species, genetic structure was higher and genetic diversity was lower among fragmented populations than among those in the nature reserves. In addition, assignment tests and spatial autocorrelation revealed that small distances of about 500 m through fragmented landscapes are a barrier to O. reticulata but not for G. variegata. These data support our hypothesis that G. variegata disperse more readily and more frequently than O. reticulata and that dispersal and habitat specialization are critical factors in the persistence of species in habitat remnants.
A new marine gastrotrich from the State of São Paulo (Brazil), with a key to species of Pseudostomella (Gastrotricha, Thaumastodermatidae)

Abstract In previous papers, faunistic and preliminary taxonomic data on the gastrotrich communities along the coastline of the Brazilian states of São Paulo and Rio de Janeiro were reported; among the over 40 records, the occurrence of several species new to science was highlighted. One of such new taxa is described here based on observation carried out on living and SEM prepared specimens. Pseudostomella dolichopoda sp. n. (Gastrotricha: Thaumastodermatidae) is the only species in the genus that attains 420 µm in total length, is covered by pentancres and possesses, among others, caudal pedicles up to 45 µm in length. Additional differences with co-generic taxa characterized by a pentancrous covering are discussed. Furthermore, a key to the described Pseudostomella species of the world based on easily discernible traits, visible in both living and formalin-fixed specimens, is provided.
Hepatitis C Virus Infection and Dialysis: 2012 Update

Hepatitis C virus infection is still common among dialysis patients, but the natural history of HCV in this group is not completely understood. Recent evidence has been accumulated showing that anti-HCV positive serologic status is significantly associated with lower survival in dialysis population; an increased risk of liver and cardiovascular disease-related mortality compared with anti-HCV negative subjects has been found. According to a novel meta-analysis (fourteen studies including 145,608 unique patients), the adjusted RR for liver disease-related death and cardiovascular mortality was 3.82 (95% CI, 1.92; 7.61) and 1.26 (95% CI, 1.10; 1.45), respectively. It has been suggested that the decision to treat HCV in patients with chronic kidney disease be based on the potential benefits and risks of therapy, including life expectancy, candidacy for kidney transplant, and co-morbidities. According to recent guidelines, the antiviral treatment of choice in HCV-infected patients on dialysis is mono-therapy but fresh data suggest the use of modern antiviral approaches (i.e., pegylated interferon plus ribavirin). The summary estimate for sustained viral response and drop-out rate was 56% (95% CI, 28–84) and 25% (95% CI, 10–40) in a pooled analysis including 151 dialysis patients on combination antiviral therapy (conventional or pegylated interferon plus ribavirin).
Intercellular Adhesion Molecule-5 Induces Dendritic Outgrowth by Homophilic Adhesion

Intercellular adhesion molecule-5 (ICAM-5) is a dendritically polarized membrane glycoprotein in telencephalic neurons, which shows heterophilic binding to leukocyte β2-integrins. Here, we show that the human ICAM-5 protein interacts in a homophilic manner through the binding of the immunoglobulin domain 1 to domains 4–5. Surface coated ICAM-5-Fc promoted dendritic outgrowth and arborization of ICAM- 5–expressing hippocampal neurons. During dendritogenesis in developing rat brain, ICAM-5 was in monomer form, whereas in mature neurons it migrated as a high molecular weight complex. The findings indicate that its homophilic binding activity was regulated by nonmonomer/monomer transition. Thus, ICAM-5 displays two types of adhesion activity, homophilic binding between neurons and heterophilic binding between neurons and leukocytes.
Vasodilator Action of Angiotensin-(1-7) on Isolated Rabbit Afferent Arterioles

Recent studies have shown that angiotensin-(1-7) (Ang-[1-7]), which is generated endogenously from both Ang I and II, is a bioactive component of the renin-angiotensin system and may play an important role in the regulation of blood pressure. However, little is known about its role in regulating the reactivity of the afferent arteriole or the mechanism(s) involved. We hypothesized that Ang-(1-7), acting on specific receptors, participates in the control of afferent arteriole tone. We first examined the direct effect of Ang-(1-7) on rabbit afferent arterioles microperfused in vitro, and we tested whether endothelium-derived relaxing factor/NO and cyclooxygenase products are involved in its actions. To assess the vasodilator effect of Ang-(1-7), afferent arterioles were preconstricted with norepinephrine, and increasing concentrations of Ang-(1-7) were added to the lumen. We found that 10−10 to 10−6 mol/L Ang-(1-7) produced dose-dependent vasodilatation, increasing luminal diameter from 8.9±1.0 to 16.3±1.1 &mgr;m (P <0.006). Indomethacin had no effect on Ang-(1-7)–induced dilatation. NG-nitro-l-arginine methyl ester, a NO synthesis inhibitor, abolished the dilatation induced by Ang-(1-7). We attempted to determine which angiotensin receptor subtype is involved in this process. We found that 10−6 mol/L [d-Ala7]–Ang-(1-7), a potent and selective Ang-(1-7) antagonist, abolished the dilatation induced by Ang-(1-7). An angiotensin II type 1 receptor antagonist (L158809) and an angiotensin II type 2 receptor antagonist (PD 123319) at 10−6 mol/L had no effect on Ang-(1-7)–induced dilatation. Our results show that Ang-(1-7) causes afferent arteriole dilatation. This effect may be due to production of NO, but not the action of cyclooxygenase products. Ang-(1-7) has a receptor-mediated vasodilator effect on the rabbit afferent arteriole. This effect may be mediated by Ang-(1-7) receptors, because angiotensin type 1 and type 2 receptor antagonists could not block Ang-(1-7)–induced dilatation. Thus, our data suggest that Ang-(1-7)opposes the action of Ang II and plays an important role in the regulation of renal hemodynamics.
Economic and Environmental Analysis of Investing in Solar Water Heating Systems

Solar water heating (SWH) systems can provide a significant part of the heat energy that is required in the residential sector. The use of SWH systems is motivated by the desire to reduce energy consumption and especially to reduce a major source of greenhouse gas (GHG) emissions. The purposes of the present paper consist in: assessing the solar potential; analysing the possibility of using solar energy to heat water for residential applications in Romania; investigating the economic potential of SWH systems; and their contribution to saving energy and reducing CO 2 emissions. The results showed that if solar systems are used, the annual energy savings amount to approximately 71%, and the reduction of GHG emissions into the atmosphere are of 18.5 tonnes of CO 2 over the lifespan of the system, with a discounted payback period of 6.8–8.6 years, in accordance with the savings achieved depending on system characteristics, the solar radiation available, ambient air temperature and on heating load characteristics. Financially, the installation of SWH systems determines net savings of 805–1151 Euro in a 25-year period in the absence of governmental subsidies. According to the sensitivity analysis, installing a SWH system with subsidies of up to 50% determines the reduction of the discounted payback period to 3.1–3.9 years and the increase of net savings to 1570–1916 Euro. These results indicate that investing in these systems is cost-effective for Romanian households as long as the governmental subsidies increase.
‘Suicide’ of crickets harbouring hairworms: a proteomics investigation

Despite increasing evidence of host phenotypic manipulation by parasites, the underlying mechanisms causing infected hosts to act in ways that benefit the parasite remain enigmatic in most cases. Here, we used proteomics tools to identify the biochemical alterations that occur in the head of the cricket Nemobius sylvestris when it is driven to water by the hairworm Paragordius tricuspidatus. We characterized host and parasite proteomes during the expression of the water‐seeking behaviour. We found that the parasite produces molecules from the Wnt family that may act directly on the development of the central nervous system (CNS). In the head of manipulated cricket, we found differential expression of proteins specifically linked to neurogenesis, circadian rhythm and neurotransmitter activities. We also detected proteins for which the function(s) are still unknown. This proteomics study on the biochemical pathways altered by hairworms has also allowed us to tackle questions of physiological and molecular convergence in the mechanism(s) causing the alteration of orthoptera behaviour. The two hairworm species produce effective molecules acting directly on the CNS of their orthoptera hosts.
