Authors: Amieur Toufik , Sedraoui Moussa , Amieur Oualid 
Published: April 2019

This paper deals with the robust series and parallel fractional-order <em>PID</em> synthesis controllers with the automatic selection of the adjustable performance weights, which are given in the weighted-mixed sensitivity problem. The significant contribution of the paper is to achieve the good trade-off between nominal performances and robust stability for DC motor regardless its nonlinear dynamic behavior, the unstructured model uncertainties and the effect of the sensor noises on the feedback control system. The main goal is formulated as the weighted-mixed sensitivity problem with unknown adjustable performance weight. This problem is then solved using an adequate optimization algorithm and its optimal solution leads to determine simultaneously the robust fractional <em>PID</em> controller, which is proposed by the series and the parallel fractional structures, As well as, the obtained optimal solution determines the corresponding adjustable performance weight.<strong><em> </em></strong>The proposed control technique is applied on DC motor where its dynamic behavior is modeled by unstructured multiplicative model uncertainty. The obtained performances are compared in frequency- and time-domains with those given by both integer controllers such classical <em>PID</em> and <em>H<sub>∞</sub> </em>controllers.
Analytically Modeling, Design and Analysis a Nonlinear Controller for a STATCOM operations
Authors: Moharana J. K. 
Published: April 2019

The concept of H Control is extended, in principle, to the SVPWM (Space Vector Pulse Width Modulation) based inverter switching of a STATCOM (STATic synchronous COMpensator) device. The SVPWM assures a greater value of modulation factor in the undermodulation as well as the overmodulation range compared to SPWM (Sine Pulse Width Modulation) i.e. a much higher fundamental content. In the present work, the STATCOM has been modeled and its model is nonlinear in (phase angle between fundamental of system voltage and output voltage of STATCOM. The effect of increased modulation index and lower harmonic distortion has been studied through simulation w.r.t. different performance indices and dynamic response of relevant variables. A PI and an H Controller have been designed for closed-loop control of the system. It is found through simulation that H controller gives better response than PI controller for nonlinear system.

Published: April 2019

<p>The fishing industry plays a major role in development of Indian economy. The recent attacks on fishermen taking place in Indo-Srilanka and Indo-Pakistan maritime boundaries have been major concerns. These attacks are primarily caused by the lack of navigation and security features during the voyage. Hence the current situation demands the implementation of precise facilities for reducing man and material loss. This project involves the design and implementation of a Low cost Navigation and Security System for Indian fishermen on Arduino Nano platform. The system developed solves the above said issues by continously tracking the location of fishing vessel and providing minimal security features. The system ensures that navigation is in safe zone within the nation’s maritime boundary and also prevents crossover. This is acheived using GPS receiver which directly links to GPS satellites for current location of the vessel. The required data fields like the latitude and longitude data along with the time stamps are extracted from the GPS samples and used for comparision for determining the exact location of the vessel. This procedure will help in detection of corner cases when the vessel is nearing or about to crossover the maritime boundary, which cannot be marked physically. It is useful for triggering conditions like enabling or disabling fuel injection system, the warning beeps and display notifications to the fishermen. Manual override facility for restarting the engine in case of crossover for limited duration is provided. The security features like authentication for the genuine operator to get access to the engine panel, the support for distress message and the storage of the exact time stamps and GPS locations after encryption in case of initiation of transmitting distress message is provided as a blackbox feature. The passcode based mechanism allows for maximum of three attempts to unlock access to control panel. The GSM modem allows for transmission of distress message to the registered base station/coast guard. The encrypted GPS samples and time stamps are stored in on-chip EEPROM memory for future reference. <strong></strong></p>

Published: April 2019

<p>Crosstalk is one of the problems that affect the performance operation of global system mobile (GSM) network. Among the effect of crosstalk are call mute, call drop, wire propagation delay, dynamic power dissipation etc. Crosstalk is an undesirable signal arising due to the coupling capacitances between adjacent interconnecting wires and measured in decibel. In this paper some literature were reviewed and different ways of measuring crosstalk such as Near end croosstalk (NEXT), far end crosstalk (FEXT), Power sum crosstalk (PSNEXT) and alien crosstalk (AXT) were analyzed. </p>

Revision of Neotropical aphrophorine spittlebugs, part 1: Ptyelini (Hemiptera, Cercopoidea)
Authors: HAMILTON K. G. ANDREW 
Published: April 2019

Cephisus Stål, formerly with only 3 recognized species, is now known from at least 10 species ranging from southwestern USA to Argentina. Eight are keyed and described, including C. siccifolia (Walker), the economic species in South America, C. variolosus (Walker), the common species in Central America, C. brevipennis sp. nov. and C. laticeps sp. nov. from Mexico, plus C. magnificus sp. nov. from Brazil; two other biological species were identified in the C. variolosus species complex from the results of genetic “barcoding.” These are differentiated from Plinthacrus phaleratus, P. mexicanus and P. irroratus (all described by Spinola in 1850) that are new synonyms of Novaphrophara tasmaniae Lallemand, 1940 (as N. phalerata comb. nov.), a species collected recently only in Madagascar. These two genera along with 6 others are placed in the redefined tribe Ptyelini (= Takagiinae syn. nov.) as sister-genus to the palaearctic genus Cnemidanomia Kusnezov (=Takagia Matsumura), suggesting a pre-Oligocene dispersal from the old world to the new. A preliminary key is provided to the families and tribes of Cercopoidea represented in the new world.

The Indian sillago, Sillago indica McKay, Dutt & Sujatha, 1985, is redescribed on the basis of three paratypes and two newly collected specimens. The presence of two posterior extensions of the swimbladder instead of one suggests that it belongs to the subgenus Sillago. Comments on its subgeneric status and comparisons with members of Sillago (Sillago) are provided. Two specimens collected from Vietnam represent the first record of the species from the South China Sea, western Pacific Ocean.
Relations of the Low-Level Extratropical Cyclones in the Southeast Pacific and South Atlantic to the Atlantic Multidecadal Oscillation

Published: April 2019

AbstractThe relations of the low-level extratropical cyclones in the southeastern Pacific and South Atlantic with the sea surface temperature (SST) anomalies associated with the Atlantic multidecadal oscillation (AMO) during the summer and winter of the 1979–93 cold AMO (CAMO) and 2003–17 warm AMO (WAMO) are analyzed. During both seasons and in both AMO phases, the cyclone trajectories defined by cyclone local counts exceeding 10 events per grid box occur approximately in the areas with the AMO-related positive SST anomalies. The cyclone densities in most latitudes during both seasons are higher in the CAMO than in the WAMO. Thus, the cyclone density in the study domain presents a reduction trend during the 1979–2017 period. The large-scale northward SST anomalous gradients between the bands north and south of 40°S increase the long-wave baroclinicity in the midlatitudes in the WAMO, and the southward SST anomalous gradients decrease it in the CAMO. Consequently, the short-wave baroclinicity is higher in the WAMO than in the CAMO in the southeastern Pacific midlatitudes. Thus, the cyclones are more energetic in the WAMO than in the CAMO. In the South Atlantic region off the Argentinean coast, both the barotropic and baroclinic conversion terms are positive, indicating an increase of the kinetic energy of the short waves. The low-level cyclones in the southeastern Pacific and South Atlantic are modulated by the AMO. As far as we know, the relation of the SH low-level extratropical cyclones to the AMO documented here was not studied before.
CORRIGENDUM
Authors: Squitieri Brian J. , Gallus William A. 
Published: April 2019

Abstract
An error was discovered in the code used to calculate neighborhood equitable threat scores (nETSs) in Squitieri and Gallus. Replicating results with the error corrected revealed that most of the conclusions from Squitieri and Gallus remained the same, but with one significant new finding and one notable change in results. In the original manuscript, very few correlations between MCS QPF skill and LLJ forecast accuracy could be denoted among weakly forced cases, with none of them being statistically significant. Applying the aforementioned correction, it was found that QPF skill during the mature stage of MCSs significantly correlated with moisture forecast accuracy within developing LLJs for weakly forced events. It was also found that correlations between MCS QPF skill and LLJ potential temperature forecast accuracy occurred earlier in the evening.

Authors: Malfitano Ana Paula Serrata , de Souza Rosangela Gomes da Mota , Townsend Elizabeth A. , Lopes Roseli Esquerdo 
Published: April 2019

Background. Occupational justice and related concepts can inform practices directed at injustice and the lack of rights in daily life. Brazilian ideas about social occupational therapy seem to be similar to these concepts about inequality. Purpose. This study aimed to answer the questions, “Do occupational justice concepts inform occupational therapists’ professional actions?” and “How are occupational justice concepts connected to Brazilian ideas about social occupational therapy?” Method. A secondary analysis was undertaken of a scoping review using occupational justice and related concepts as keywords. Descriptive and categorical analyses were used to classify the extract data. Findings. We selected 42 articles that specify occupational therapy practices, classified as individual approaches ( n = 13), individual-integrated-with-social approaches ( n = 22), and social approaches ( n = 7). It was found that occupational justice concepts have informed individual approaches and that the second and third approaches can be connected with social occupational therapy. Implications. Dialogue for sharing knowledge, concepts, and practices of occupational therapy worldwide can be inspired by this review.
Cost Benefit and Utility Decision Analysis of Turbinoplasty with Adenotonsillectomy for Pediatric Sleep‐Disordered Breathing
Authors: Baik Grace , Brietzke Scott E. 
Published: April 2019

ObjectivesUse decision analysis techniques to assess the potential utility gains/losses and costs of adding bilateral inferior turbinoplasty to tonsillectomy/adenoidectomy (T/A) for the treatment of obstructive sleep‐disordered breathing (oSDB) in children. Use sensitivity analysis to explore the key variables in the scenario.Study DesignCost‐utility decision analysis model.SettingHypothetical cohort.Subjects and MethodsComputer software (TreeAge Software, Williamstown, Massachusetts) was used to construct a decision analysis model. The model included the possibility of postoperative complications and persistent oSDB after surgery. Baseline clinical and quality‐adjusted life year (QALY) parameters were estimated using published data. Cost data were estimated from Centers for Medicare and Medicaid 2018 databases (www.cms.gov). Sensitivity analyses were completed to assess for key model parameters.ResultsThe utility analysis of the baseline model favored the addition of turbinoplasty (0.8890 vs 0.8875 overall utility) assuming turbinate hypertrophy was present. Sensitivity analysis indicated the treatment success increase (%) provided by concurrent turbinoplasty was the key parameter in the model. A treatment success increase of 3% of turbinoplasty was the threshold where concurrent turbinoplasty was favored over T/A alone. The incremental cost‐effectiveness ratio (ICER) of $27,333/QALY for the baseline model was favorable to the willingness‐to‐pay threshold of $50,000 to $100,000/QALY for industrialized nations.ConclusionsThe addition of turbinoplasty for children with turbinate hypertrophy to T/A for the treatment of pediatric oSDB is beneficial from both a utility and cost‐benefit analysis standpoint even if the benefits of turbinoplasty are relatively modest.

Authors: Castellano Alexa , Sharma Arun 
Published: April 2019

ObjectiveTo systematically review the available evidence on the effects of transoral robotic surgery (TORS) on the posttreatment quality of life (QOL) and swallow function of patients with head and neck cancer.Data SourcesPubMed and Ovid electronic databases were searched from inception to July 6, 2016. Specific database functions were applied to maximize the search.Review MethodsArticles in the database were reviewed for inclusion by 2 independent reviewers according to predetermined eligibility criteria. The references of relevant articles were then hand‐searched to identify additional manuscripts. For included articles, the study characteristics and relevant data were extracted.ResultsOf 103 articles screened, 20 reporting validated measures of QOL and/or swallow outcomes for 659 patients were eligible for inclusion. Fourteen were observational studies or case series and did not compare the TORS group with another intervention. Two were prospective nonrandomized clinical trials that compared outcomes between TORS and primary chemoradiation. Four were cohort studies comparing TORS with other treatment approaches and modalities, including open surgical approaches and transoral laser microsurgery. Overall, most patients who underwent TORS ± adjuvant therapy reported a return to baseline QOL and swallow function by 6 to 12 months posttreatment. Several studies demonstrated superior QOL and swallowing outcomes when compared with primary chemoradiation or open approaches.ConclusionsAvailable evidence suggests that patients who undergo TORS for head and neck cancer have good QOL and swallowing outcomes after treatment, but outcomes are dependent on baseline function, T stage, and adjuvant treatment status.

Published: April 2019

Background: Two major constituents of cannabis are Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is the main psychoactive component; CBD may buffer the user against the harmful effects of THC. Aims: We examined the effects of two strains of cannabis and placebo on the human brain’s resting-state networks using fMRI. Methods: Seventeen healthy volunteers (experienced with cannabis, but not regular users) underwent three drug treatments and scanning sessions. Treatments were cannabis containing THC (Cann−CBD; 8 mg THC), cannabis containing THC with CBD (Cann+CBD; 8 mg THC + 10 mg CBD), and matched placebo cannabis. Seed-based resting-state functional connectivity analyses were performed on three brain networks: the default mode (DMN; defined by positive connectivity with the posterior cingulate cortex: PCC+), executive control (ECN; defined by negative connectivity with the posterior cingulate cortex: PCC−) and salience (SAL; defined by positive connectivity with the anterior insula: AI+) network. Results: Reductions in functional connectivity (relative to placebo) were seen in the DMN (PCC+) and SAL (AI+) networks for both strains of cannabis, with spatially dissociable effects. Across the entire salience network (AI+), Cann−CBD reduced connectivity relative to Cann+CBD. The PCC in the DMN was specifically disrupted by Cann−CBD, and this effect correlated with subjective drug effects, including feeling ‘stoned’ and ‘high’. Conclusions: THC disrupts the DMN, and the PCC is a key brain region involved in the subjective experience of THC intoxication. CBD restores disruption of the salience network by THC, which may explain its potential to treat disorders of salience such as psychosis and addiction.

Authors: Bakshi Neil K. , Inclan Paul M. , Kirsch Jacob M. , Bedi Asheesh , Agresta Cristine , Freehill Michael T. 
Published: April 2019

Background: Several recommendations have been made regarding pitch counts and workload for baseball players of different levels, including Little League, high school, collegiate, and professional baseball. However, little consensus is found in the literature regarding the scientific basis for many of these recommendations. Purpose: The primary purpose of this study was to summarize the evidence regarding immediate and long-term musculoskeletal responses to increasing pitching workload in baseball pitchers of all levels. A secondary purpose of this review was to evaluate the extent to which workload influences injury and/or performance in baseball pitchers. Study Design: Systematic review. Methods: We performed a systematic search in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for studies addressing physiologic and/or pathologic musculoskeletal changes in response to a quantifiable pitching workload. We included studies examining the effects of pitching workload on performance, injury rate, and musculoskeletal changes in Little League, high school, collegiate, and professional baseball players. Results: We identified 28 studies that met our inclusion and exclusion criteria: 16 studies regarding Little League and high school pitchers and 12 studies regarding collegiate and professional pitchers. The current evidence presented suggests that increased pitching workload may be associated with an increased risk of pain, injury, and arm fatigue in Little League and high school pitchers. However, little consensus was found in the literature regarding the association between pitching workload and physiologic or pathologic changes in collegiate and professional pitchers. Conclusion: Evidence, although limited, suggests the use of pitch counts to decrease injury rates and pain in Little League and high school baseball pitchers. However, further research must be performed to determine the appropriate number of pitches (or throws) for players of different ages. This systematic review reported conflicting evidence regarding the use of pitch counts in college and professional baseball. Future high-quality research is required to determine the role, if any, of pitch counts for collegiate and professional pitchers.
