Direct Biocontrol of Telemanipulators and VR Environments Using SEMG and Intelligent Systems

Virtual Reality describes a 3-D computer generated environment, controlled by the user from a remote location. VR has applications in robotics, entertainment and medical field. Virtual Reality robotic systems have been a major help in hazardous environments and in areas which need a high degree precision such as nuclear plants and tele-surgery. An ideal VR system immerses the user in the virtual environment. This condition is termed as telepresence. The components of a VR system are human operator, interface system and teleoperator. VR system relies on human interface performance for its high accuracy. Commercially available interfaces such as Data Gloves and exoskeleton devices provide less accuracy and restricted motion. A biocontrol interface utilizing human physiological signals such as Electromyogram (EMG) would be a natural and synergistic way of controlling a remote teleoperator. Previous studies (Suryanarayan and Reddy) have shown that surface EMG (SEMG) from flexor muscle can be effectively used as a human interface for controlling teleoperators for dynamic motion of elbow joints. The goal of the present study was to investigate the use of SEMG from extensor muscle to control real time dynamic movement of index finger at various speeds for full range. Normal subjects were asked to rhythmically flex and extend the index finger at different speeds. The actual angle was measured using a miniature accelerometer. SEMG from extensor muscle (Extensor iii Digitorum Superficialis (EDS)) was used to correlate with angle made by index finger at various speeds, with all other fingers at constant position. Parameters were extracted from SEMG. Neural networks were trained with input as extracted parameters and targets as measured angles. Best five networks were recruited for each committee. Two committees for each speed were formed. The committees were evaluated using data from new subject and the errors between actual and predicted joint angle was calculated. The committees were able to predict the joint angle at different speeds. The RMS errors between the predicted and the actual angle were found to be between 327%. The errors were more in the flexion region as compared to the extensor region. The study demonstrated the use of SEMG from EDS for the prediction of joint angle at different speeds. It also demonstrated the use of committee neural networks (CNN) in control related prediction problems. The study has taken a step forward in the direct biocontrol of telemanipulator and VR environments using SEMG. The study would find an application in medicine and control of robotic assist devices.

An Analysis of the Tourism Marketing Performance and Strategy of Ethiopia

Tourism is one of the fast-growing industries in the world and has been considered as the main driver of world trade and prosperity. According to the UNWTO (2016), it contributes 10% of global GDP (US$ 7 trillion), 5% of world exports (US$1.5 trillion) and one in 11 jobs worldwide. Ethiopia, the origin of humankind and the only un-colonized country in the continent of Africa, tops the list in the region having 12 UNESCO inscribed world heritage sites. However, the performance of the tourism sector in the country is very poor, and in terms of travel and tourism competitiveness, Ethiopia is ranked 118 th out of 141 countries in 2015 (WB, 2012; MoCT, 2015 & WEF, 2015). Cognizant of several reasons for this imbalance, the premise of this research was focused on a pre-assumption that either the tourism marketing strategy has been inappropriately formulated and implemented or even overlooked. A descriptive study was conducted to evaluate the performance of the tourism marketing practices of the government of Ethiopia. The tourism marketing strategy for Ethiopia (2016-2020) was critically reviewed and both strengths and weaknesses of the strategic document were identified. The study has revealed that the performance of tourism marketing practice is low (below regional average in most indicators), although the country has a good market growth rate. Notwithstanding a few pitfalls, the analysis showed that the existing tourism marketing strategy of the country was successfully formulated. It has been suggested that the government can concentrate more on the materialization of weak positions and modify the existing strategic documents accordingly so that the tourism marketing performance can improve.

TEMPERATURE DEVELOPMENT IN SCREW EXTRUDERS By: Chris Rauwendaal and Giuseppe Ponzielli

Viscous dissipation and the resulting increase in melt temperature are important in most polymer extrus ion operation. Existing theories do not allow a simple prediction of temperature development without resorting to numerical techniques. This paper describes the development of a analytical theoretical model that allows calculation of developing melt temperatures in a single screw extruder. The model based on simplified flow in screw extruders. Initially we consider only flow in the screw channel and assume the leakage flow through the flight clearance is negligible. The dissipation in the flight clearance is added later.
Control of MHD Instabilities in the STORM Tokamak using Resonant Helical Coils

The resonant interaction between magnetohydrodynamic (MHD) instability modes and an externally applied helical magnetic field has been investigated in the Saskatchewan Torus-Modified (STOR-M) tokamak. The study has been carried out numerically using a 2D MHD equilibrium code and also experimentally using an l = 2/n = 1 helical coils through which a DC current pulse is applied during normal Ohmic discharge. It has been found numerically that the helical current can effectively suppress the resonant (m = 2, n = 1) magnetic islands when the value of safety factor at the plasma edge is relatively low (≤ 4). Also, it has been found numerically that (2, 1) islands with disruptive nature may be induced when the applied current exceeds a certain limit. Experimentally, significant suppression in the (2, 1) tearing mode fluctuations has been observed during the application of resonant field on STOR-M discharges. The suppression of (1, 1), (3, 1) and (4, 1) mode perturbations has been also observed. Furthermore, the resonant field induced a phase with reduced Hα radiation level, reduced loop voltage, and increased soft x-ray (SXR) emission.
Validation of a Self-Report Clinical Decision-Making Tool Using Rasch Analysis

Introduction. No objective tools exist that assess the level and progression of clinical decision-making (CDM) skills in Doctor of Physical Therapy (DPT) students. Tools in other health professions exist but are not applicable or transferable to DPT education. The purpose of the current study is to validate an objective tool to assess DPT students' perceptions of their CDM skills across a curriculum. Methods. This is a cross-sectional, observational design study, using a convenience sample of DPT students enrolled in a DPT program. Four phases of data collection, representing four iterations of the CDM tool, are included. A self-report tool assessing CDM using a Likert scale was sent to the participants through email. Data were analyzed using Rasch analysis after each phase of data collection, which led to survey revisions and further data collection. Results. The tool demonstrated high internal consistency throughout the four phases of data collection. The tool measures one construct, CDM. The Likert scale levels discriminated well between the different ability levels on all items. The scores on the CDM tool provided known groups validation of the tool. The tool has a ceiling effect, floor effect, and is unable to differentiate CDM skills for DPT graduates who have been practicing for >1 year. Discussion. Clinical decision making is a complex, highly individualized construct. This CDM tool distinguishes the students' perceived level of CDM ability across the different class years of a DPT curriculum. The sample was one of convenience. Further research increasing the heterogeneity of the sample will assist with increasing the generalizability of the tool.
NOTES ON SOME NOTEWORTHY LICHENS AND ALLIED FUNGI F OUND IN THE BIAŁOWIE śA PRIMEVAL FOREST IN POLAND

A list of 41 lichens and allied fungi new to Polan d or otherwise of floristic interest is presented. It includes 30 lichens, nine lichenicolous fungi an d two saprobic fungi. Three species, Cheiromycina petri , Lobaria amplissima and Taeniolella delicata (with Loxospora elatina as a new host) are reported for the first time from Poland. Lobaria virens should be excluded from the Polish lichen checklis t as the record can be referred to L. amplissima. Pertusaria ophthalmiza should be added to the new edition of Polish check list as old records were previously overlooked. Three species are reported as new to the Polish low land, five as new to NE Poland and 18 as new to the Białowie Ŝa Primeval Forest. Chemotypes of Chrysothrix candelaris were investigated for the first time in Poland. Add itionally, Pertusaria ophthalmiza is reported for the first time from the Polish Carpathians.
Machine scheduling for multitask machining

Multitasking is an important part of today’s manufacturing plants. Multitask machine tools are capable of processing multiple operations at the same time by applying a different set of part and tool holding devices. Mill-turns are multitask machines with the ability to perform a variety of operations with considerable accuracy and agility. One critical factor in simultaneous machining is to create a schedule for different operations to be completed in minimum make-span. A Mixed Integer Linear Programming (MILP) model is developed to address the machine scheduling problem. The adopted assumptions are more realistic when compared with the previous models. The model allows for processing multiple operations simultaneously on a single part; parts are being processed on the same setup and multiple turrets can process a single operation of a single job simultaneously performing multiple depths of cut. A Simulated Annealing algorithm with a novel initial solution and assignment approach is developed to solve large instances of the problem.
Seismic Response of Systems founded on Isolated footings on top of alluvial basins aper Title Line 1 Footings on top of Alluvial Basins

Scope of this paper is the preliminary quantification of the role of 2D wave scattering effects on the seismic response of simple structures. To this end, the paper explores the response of an 1-dof system and a frame founded on the surface of alluvial valleys employing fully non-linear numerical analyses with due account of Soil-Structure Interaction effects. By properly modeling the soil-foundation interface, analyses are able to capture phenomena associated with soil yielding and foundation detachment. It is shown that valley effects may provoke unexpected response of the foundation due mainly to the generation of a geometry-induced synchronous parasitic acceleration. The latter may under circumstances cause uplifting of the foundation which may provisionally either impose severe stressing on the superstructure or reduce the amount of inertia transmitted to structural members thus being beneficial under even extreme shaking conditions.
Reusing Past Replies to Respond to New Email: A Case-based Reasoning Approach

Email communication has been widely used in managing customer queries, such as complaints and inquiries. The user is expected to respond the query properly. However, with an increasing number of query emails received every day, it seems likely that the inbox appears to have more unreplied queries and leads to overwhelmed and cluttered email management called email overload. This thesis presents a development in the email overload issue on managing a reply task. The system, called a smart email client, helps in replying to an email by suggesting a list of replies gleaned from the emails replied to in the past. These suggested replies are ranked according to the level of similarity. The methodology follows the Case-Based Reasoning (CBR) approach to solve the problem by reusing previously written solutions from the past replies stored in the case base. Techniques from Natural Language Processing and Information Retrieval are utilised, particularly in lexical semantics, through using WordNet. Finally, an evaluation of the retrieval algorithm shows that the effectiveness and efficiency of the algorithm is influenced by the case feature selection and various text analysis techniques such as lexical analysis, stemming, stopwords removal, and synonym expansion.
Design of a Planar, Concentric Coil for the Generation of a Homogeneous Vertical Magnetic Field Distribution

─ This paper describes an algorithm to design a planar, concentric coil that generates a homogeneous vertical magnetic field distribution, with a target self inductance. The algorithm consists of several steps. The first step is the random generation of a large set of concentric coils, taken into consideration a number of boundary conditions such as the outer dimensions and the radius of the conducting wire. The optimal coil is found from this set after a twofold selection, namely on the self inductance value and on the uniformity of the vertical magnetic field, which was evaluated using a cost function. The algorithm is straightforward and based on closed expressions, which leads to a rapid execution of the procedure. We evaluated the algorithm on a representative reference configuration. The best coil of the large set was selected and the quasi-uniform field distribution of this coil was confirmed by experimental verification. Index Terms ─ Magnetic field, planar coil, self inductance, uniform field distribution.
IMPACT OF PEER ASSESSMENT INTERVENTION ON STUDENT MOTIVATION AND LEARNING IN COMPOSITION CLASSES

Purpose – This study sets out to investigate the impact of the peer assessment intervention on student motivation and learning given the numerous calls by stakeholders in higher education institutions to make assessment criteria more explicit. Methodology – The sample involved two groups of students, 65 in total, enrolled in a first-year writing course. The intervention group was subjected to a peer assessment workshop while the other served as the control group. A 45 item Likert scale questionnaire was administered on both groups subsequently. Findings – Results from independent sample T-tests and Pearson Chi-Square test of independence showed that increased levels of motivation and better learning strategies were reported by the intervention group compared to the control group except for one dimension of learning peer learning. A moderate strength of association was reported between the peer review intervention and the dimensions of motivation whereas the strength of association between peer review intervention and the dimensions of learning strategies was weak. Significance – The study reinforces that socialization processes are pertinent and that instructors should bring their learners in as full partners for the meaningful transfer of tacit knowledge. Peer review has shown to provide students with the ability to take control of their own successes.
Method of segmenting river from remote sensing image

This paper presents a method of segment the river area in remote sensing images. The spectral distribution of the river area in the image is relatively uniform, and the overall gray level is dark, And the spectrum is evenly distributed regardless of direction, but land area spectral information is very messy, most of the land in the regional spectral distribution is not uniform, maybe some land area spectral distribution is more uniform, but has a certain direction, this paper according to these characteristics, using the cross-type template, the regional variance is used as the regional texture characteristic to obtain the adaptive threshold to obtain the adaptive binary graph. The river is usually a connected water, only a large enough area to determine the river, so the use of binary image marking algorithm to obtain the largest connected area, marked as a river. This paper presents the method of river segmentation. Experiments show that the river segmentation is suitable for remote sensing images with relatively large river regions.

The results showed that the values of early fatalities and early fatality risk show maximum value at the stable atmospheric condition with low wind speed and heavy rainfall rate. The information obtained through this research will be used in developing scenarios for the risk estimation in order to make strategies for reducing offsite health consequences.
Polymorphism of DGAT 1 Gene and Its Rela ti onship with Carcass

Nowadays because of very rapid advances in molecular genetics, accurate and rapid identification of genes controlling traits prepared. Using molecular markers in animal breeding, a combination of quantitative and molecular genetic methods was applied to identify genes controlling meat quality (Meuwissen et al. 2001). Studies to find genes affecting carcass traits in beef cattle led to the discovery of the DGAT1 gene as a candidate gene for meat quality and quantity (Pannier et al. 2010; Souzaet al. 2010). Diacylglycerol o-acyltransferase 1 (DGAT1) is a microsomal enzyme that catalyzes the final step of triglyceride synthesis (Winter et al. 2002). Because of its role in triacylglycerol synthesis and energy storage, DGAT1 also may be involved in intestinal fat absorption, lipoprotein assembly and the regulation of plasma triacylglycerol concentrations, fat storage in adipocytes, energy metabolism in muscle and milk production including mammalian oocytes (Cases et al. 1998). DGAT1 gene is widely expressed in many tissues, with the highest expression levels in adipose tissue and small intestine (Chen and Farese, 2000; Buhman et al. 2002). Over expression of DGAT1 in white adipose tissue of transgenic mice increases adipocyte size and adipose mass and the level of DGAT1 over-expression correlate with the degree of adiposity (Chen et al. 2002). A silent mutation of GCC (Ala 487) to GCT (Ala 487) was found in exon 17 at the 8539 base pair in 286 lambs of three Chinese breeds by polymerase chain reaction single nucleotide conformation polymorphism assay. The TT genotype conferred The diacylglycerol acyltransferase 1 gene (DGAT1) was identified as a strong candidate gene affecting mutton quality traits in sheep. Single nucleotide polymorphism creates a single base mutation (C to T) in AGCT site of endonuclease AluI. DGAT1 is one of the candidate genes to improve carcass characteristics in feedlot animals. In order to study area T487C in exon 17 of the DGAT1 polymorphism, Iranian Moghani sheep breeds randomly slaughtered in the abattoir were recorded. DNA was extracted from 150 samples of Moghani sheep. Polymerase chain reaction to amplify 309 bp of exon 17 DGAT1 gene using a pair of specific primers was performed. Genotypes obtained from method PCR-RFLP and directly from agarose gel. Two alleles T and C with frequencies of 0.829 and 0.171 were observed respectively. Statistical analysis showed polymorphism in exon 17 region of the gene significantly correlated with carcass weight and dressing percentage (P<0.05). So that the CC genotypes of the significant mean carcass weight and dressing percentage heavier than had TT genotypes (P<0.05). Of polymorphism can be observed that improvement in breeding programs to improve carcass weight and dressing percentage through selection in favor of superior genotypes be used.
AGE PERCEPTION AND SPORTS CAREER IN THE WOMEN'S ARTISTIC GYMNASTICS

Women's Artistic Gymnastics (WAG) is an Olympic sport that has produced young girls celebrities over time, which has been extensively criticized for producing "little pixies. " The present research was generated by the project "Coming of age: Towards best practice in Women's Artistic Gymnastics" (Kerr, Barker-Ruchti, Schubring, Cervin, Nunomura, 2015), whose focus was to analyze the experiences of older gymnasts and the factors that contributed to the prolongation of their career. The participants of this study were former gymnasts and are still active in Portugal, at the high level. We conducted a semi-structured interview to collect participants' reports and the thematic analysis was used as data treatment. The perception of becoming physically older was the most difficult fact to manage among the majority of respondents. The experience of being "older" gymnasts has helped them to understanding how particular contexts happen and thus face the challenges of the new phase of their careers. The factors that influence the development of the career have been to soften the myth that mature women would not compete internationally in the WAG; to propose alternatives for training in order to preserve the general health of gymnasts; propose guidelines for the management of the sports career. In short, we bring about future research into what could be done, which should not be done; or what should be avoided, by coaches, gymnasts and stakeholders in general to further the career of WAG gymnasts.
