Investigating the impedance characteristic of human arm for development of robots to co-operate with human operators

In the near future many aspect of life will be encompassed by tasks performed in co-operation with robots. As a result, robots need to be made human-friendly and to execute tasks in co-operation with humans. Control systems for such robots should be designed to work by imitating human characteristics. We aim to achieve these goals by controlling a simple one degree-of-freedom robot. First, the impedance characteristics of the human arm in a co-operative task are investigated. Then, these characteristics are implemented in a robot which performs a co-operative task with a human. The proposed control method produced good characteristics for robots co-operating with humans.
Globalization, Acquisitions and Endogenous Firm Structure

A model of heterogeneous firms with multiple products and endogenous firm structure is developed to investigate how firms respond to trade liberalization. Firm-level productivity is endogenized as firms acquire capital through mergers and acquisitions to reach optimal product scope (number of products) and capital scale (the amount of capital in each plant). The analysis shows that while more efficient firms produce more products, plant and firm level capital have an inverse U-shaped relationship with firm efficiency. A firm responds to different types of trade liberalization differently, leading to different redistribution of capital and productivity. In an importing country that opens to trade unilaterally, capital moves from high efficiency firms to low efficiency firms, and firm and industry productivity increase. Under bilateral trade liberalization, capital moves from low efficiency fi rms to high efficiency firms, and productivity may increase or decrease. The analysis highlights the importance of resource reallocation after trade liberalization and the linkage between product and acquisition markets.
UWB Pacman-Shaped Antenna with Two Frequency Rejection Bands Shaimaa ' Naser

─ In this paper, the design and analysis of microstrip-fed low-profile, compact ultra-wideband (UWB) monopole antenna with two band-notches characteristics is carried out. The antenna is mounted on a low-cost FR-4 substrate with dimensions of 25×38×1.6 mm, and relative permittivity of 4.4. The original shape of the patch is circular with radius of 11.5 mm, and then a sector is removed from the patch (making it a Pacmanshaped antenna) to improve the impedance bandwidth. The proposed antenna provides an impedance bandwidth between 2.9-15 GHz with better than 10 dB return loss and has nearly an omni-directional radiation pattern. Additionally, the antenna can reject the interference from WiMAX (3.5 GHz center frequency) and WLAN (5.5 GHz center frequency). Index Terms ─ Monopole antennas, notch filters, ultra wideband antennas.
Multifunctional Toxins in Snake Venoms and Therapeutic Implications: From Pain to Hemorrhage and Necrosis

Animal venoms have evolved over millions of years for prey capture and defense from predators and rivals. Snake venoms, in particular, have evolved a wide diversity of peptides and proteins that induce harmful inflammatory and neurotoxic effects including severe pain and paralysis, hemotoxic effects, such as hemorrhage and coagulopathy, and cytotoxic/myotoxic effects, such as inflammation and necrosis. If untreated, many envenomings result in death or severe morbidity in humans and, despite advances in management, snakebite remains a major public health problem, particularly in developing countries. Consequently, the World Health Organization recently recognized snakebite as a neglected tropical disease that affects ~2.7 million p.a. The major protein classes found in snake venoms are phospholipases, metalloproteases, serine proteases, and three-finger peptides. The mechanisms of action and pharmacological properties of many snake venom toxins have been elucidated, revealing a complex multifunctional cocktail that can act synergistically to rapidly immobilize prey and deter predators. However, despite these advances many snake toxins remain to be structurally and pharmacologically characterized. In this review, the multifunctional features of the peptides and proteins found in snake venoms, as well as their evolutionary histories, are discussed with the view to identifying novel modes of action and improving snakebite treatments.
Model based optimal control for integrated building systems

Building performance simulation has traditionally concentrated on the use of basic and conventional control methods, which are of limited use since they cannot solve all the challenges encountered. With this regard, there is a great interest in the concept of modern control strategies for integrated building systems. To explore this potential, the paper focuses mainly on the application of model-based optimal control to buildings. In this case, a performance criterion minimized by linear programming is proposed in order to maintain the temperature of indoor environment comfortable while minimizing energy consumption. Particularly, this paper is concerned with the relevance and reliability of integrating control and building performance simulation environments by run-time coupling, over TCP/IP protocol suite. In addition, this paper involves a case-study with two important steps; the first step consists of experiments obtained in a test-cell that demonstrate the potential ability of advanced control strategies in buildings, and then simulation results are obtained with the use of distributed control and building performance simulation software by run-time coupling.
Laterality and Human Speciation

Summary. Although cerebral asymmetries abound in non-human animals, there are still reasons to suppose that there may have been a single-gene mutation producing a ‘dextral’ (D) allele, which created a strong bias toward right-handedness and left-cerebral dominance for language at some point in hominid evolution. The alternative ‘chance’ (C) allele is presumed directionally neutral, although there may be other influences producing weak population manual and cerebral asymmetries in the absence of the D allele. It is unlikely that this laterality gene is located in homologous regions of the X and Y chromosomes, as suggested by Crow (1998), but there is a case for supposing that it is located solely on the X chromosome. I argue that language evolved from manual gestures, and the D allele may have served to guarantee manual and vocal control in the same (left) hemisphere in the majority of humans. The ‘speciation event’ that distinguished Homo sapiens from other largebrained hominids may have been a switch from a predominantly gestural to a predominantly vocal form of language.
Scaling of entanglement support for matrix product states

The power of matrix product states to describe infinite-size translational-invariant critical spin chains is investigated. At criticality, the accuracy with which they describe ground-state properties of a system is limited by the size $\ensuremath{\chi}$ of the matrices that form the approximation. This limitation is quantified in terms of the scaling of the half-chain entanglement entropy. In the case of the quantum Ising model, we find $S\ensuremath{\sim}\frac{1}{6}\text{log}\text{ }\ensuremath{\chi}$ with high precision. This result can be understood as the emergence of an effective finite correlation length ${\ensuremath{\xi}}_{\ensuremath{\chi}}$ ruling all the scaling properties in the system. We produce six extra pieces of evidence for this finite-$\ensuremath{\chi}$ scaling, namely, the scaling of the correlation length, the scaling of magnetization, the shift of the critical point, the scaling of the entanglement entropy for a finite block of spins, the existence of scaling functions, and the agreement with analogous classical results. All our computations are consistent with a scaling relation of the form ${\ensuremath{\xi}}_{\ensuremath{\chi}}\ensuremath{\sim}{\ensuremath{\chi}}^{\ensuremath{\kappa}}$, with $\ensuremath{\kappa}=2$ for the Ising model. In the case of the Heisenberg model, we find similar results with the value $\ensuremath{\kappa}\ensuremath{\sim}1.37$. We also show how finite-$\ensuremath{\chi}$ scaling allows us to extract critical exponents. These results are obtained using the infinite time evolved block decimation algorithm which works in the thermodynamical limit and are verified to agree with density-matrix renormalization-group results and their classical analog obtained with the corner transfer-matrix renormalization group.
An Area Wide c ontrol of Fruit Flies in Mauritius

An area-wide National Fruit Fly Control Programme (NFFCP) was initiated in 1994, funded by the European Union until 1999 and now fully financed by the Government of Mauritius. The NFFCP targets some 75,000 backyard fruit trees owners mainly. The bait application and male annihilation techniques (BAT & MAT) are currently being applied against the fruit flies attacking fleshy fruits and are targeting selected major fruit growing areas in the north, north-east, central and western parts of the island. Successful control has been achieved using these two techniques as demonstrated by trap catches and fruit samplings. The level of fruit fly damage to fruits has been reduced. Presently, the bait-insecticide mixture is being supplied free of charge to the public. The current status of the area-wide suppression programme is such that continuous use of BAT/MAT is a never ending process and as such is not viable. In this context, a TC project on 'Feasibility studies for integrated use of sterile insect technique for area- wide tephritid fruit fly control'. Studies are also being carried out on mass rearing of the peach fruit fly for small scale trials on SIT so as to eventually integrate this control method in our area-wide control programme.
Psychometric characteristics of cognitive development and achievement instruments in Round 2 of Young Lives

The main goal of the analysis presented in this paper is to establish the reliability and validity of each of the cognitive development and achievement tests administered for each age cohort within each country (Ethiopia, Peru, India and Vietnam). In this process, the items with the best psychometric properties are different across countries. Therefore, we do not carry out international comparisons of results in this paper but suggest that the test results should be used for analysis within countries (even within countries, different language groups rely on different combinations of items to establish their ability). However, the general construct measured by each test is the same across countries. Hence, a comparison of the relationships between achievement and other variables across countries is a possibility. In order to get indicators of reliability and validity, we used current standards on psychometrics to guide the analyses.
Robust Algorithm for Object Detection and Tracking in a Dynamic Scene

The main research challenge for a security and surveillance system is to create a real-time fully autonomous system that is also robust. In this research, a robust approach for real-time object detection and tracking in a dynamic scene using a moving camera is presented. The detection of the moving object and the tracking of the detected object are accomplished using a modified version of the enhanced SURF algorithm. This includes a color feature also to achieve a more accurate and robust results. This approach is able to track the detected object while reentering the scene after being absent for a short period of 4 or 5 frames. The regular SURF, enhanced SURF, and the current approach are implemented and the results are compared for speed and accuracy.

(Erysipelothrix rhusiopathiae (13.3%), Streptococcus salivarius (13.3%) and Streptococcus oralis (10%). This profile consists of commonal, soft tissue and hard tissue associated pathogen as well as an animal associated pathogens.
Exploited Application of Bacillus spp. ETL-1979 for Degradation and Decolorization of Methyl Orange, Malachite Green and Congo Red

The local industrial dye waste water sample was collected from Final Effleunt Treatment Plant (FETP) of Ankelshwar, Gujarat, India for the isolation of dye degrading bacteria. The isolate ETL-1979 was selected based on its maximum decolorization of dyes Methyl orange, Congo red and Malachite green (each 150 mg/L). Phenotypic characterization and phylogenetic analysis based on 16S rDNA sequence confirmed ETL-1979 as Bacillus sp. On physiochemical parameters optimization, Bacillus sp. ETL-1979 degraded 10.13% (0.15 mg/mL), 11.76% (0.11 mg/ mL) and 9.32% (0.8 mg/mL) of Methyl orange, Congo red and Malachite green, respectively within 2 h, whilst 100% degradation (2.97 mg/mL) at 18 h for Methyl orange, 100% (2.43 mg/mL) at 16 h for Congo red and 100% (3.18 mg/mL) at 20 h for Malachite green were recorded. The degraded products were found non-toxic in nature, while bacterial cells showed elongation and membrane rupturing under SEM taken from dye degraded media.
SIMULATION STUDY ON ENHANCING HYDROGEN PRODUCTION IN AN OCEAN THERMAL ENERGY (OTEC) SYSTEM UTILIZING A SOLAR COLLECTOR

This article reports the simulation study on the performance of utilizing a solar collector at the inlet of an evaporator to provide auxiliary heat into a system for hydrogen generation in an OTEC cycle. The conventional method of OTEC is simulated by FORTRAN programming and the results were compared with the presence of solar collector on the system. In the simulation experimental, the incoming temperature of warm seawater was boosted by using a flat plate solar collector. For the purpose of the experiment, a 100 kW OTEC cycle that was designed incorporated a solar boosting capability. Its thermodynamic efficiency was then compared through a series of simulation involving several control parameters. The results reveal that the proposed solar boosted OTEC enhanced the thermal efficiency, T E . Increase in solar power absorption can increase the net power output, thus increasing the amount of hydrogen produced. The results obtained provided insights, from a thermodynamic perspective, on the outcome of combining sustainable energy with solar thermal energy to improve the system performance.
Impact of Bacillus subtilis on midgut and silkgland of tropical tasar silkworm, Antheraea mylitta (D) Eco-race, Bhandara

Tropical tasar silkworm Antheraea mylitta is economically important insect and it produced famous tasar silk commonly known as ‘Kosa Silk’. The Indian tropical tasar silkworm is affected by disease flacherie (bacteriosis) caused by bacteria, which accounts considerable loss of 10-15 % silk cocoon production. In the present investigation histopathological effect of diseases causing bacteria in tasar silkworm, Antheraea mylitta has been studied. The bacteria from diseased rectal protrusion were isolated on specific growth media, identified as Bacillus subtilis and its effects on midgut and silk gland of tasar silkworm were investigated. During early infection, midgut epithelial cell size increased with vacuole formation. During late stage of infection, mid gut columnar epithelium cells showed hypertrophy and blabbing of plasma membrane, disruption of microvilli, vacuolization and permanent foremost nuclear changes to necrosis. The silk gland of diseased larvae showed cyto-morphological changes with reduced cell size and vacuole formation in early infection. The progressive disintegration of cytoplasmic organelles occurs with advancement of diseased in silk gland.
FACTORS AFFECTING NURSES' INTENTION TO EMIGRATE FROM THE COUNTRY IN THE CONTEXT OF THE SATISFACTION WITH EMPLOYMENT SITUATION

Introduction : Healthcare professionals’ high turnover in our country is an especially topical issue within modern conditions. The reasons behind this ongoing process are largely due to nurses’ emigration. Thus, the main task of healthcare managers is to focus their efforts on identifying the factors affecting the attitude of nurses to emigrate abroad. Materials and methods: For the purpose of an empirical sociological study, in February – April 2014 a direct individual anonymous survey on health professionals’ motivation to emigrate abroad was conducted. The opinions of 413 nurses from a university and hospitals for active treatment in Northeastern Bulgaria were included in the survey. A total of 11 types of departments and clinics, characterized by high intensity workflow, were studied. Deliverables: The results of this analysis indicate significant emigration potential among surveyed nurses. Those who are willing to leave the country are highly educated younger nurses, whose point of view is influenced by personal professional experience. The intention to practice the profession abroad is significantly motivated by various aspects of work satisfaction. Discussion: Similar to our results, a number of authors in their studies report data revealing the intention to work abroad of predominantly young professionals seeking higher payment and better perspectives for career development. Conclusion : The results demonstrate significant emigration potential among the nurses participating in the survey. Among the individual factors, those which clearly affect the intention to emigrate are professional experience, age and level of educational degree. Work satisfaction compared to experience and age has stronger influence on nurses’ attitudes to seek alternative opportunities to work outside the country.

Security Analysis of a Patient Monitoring System for the Internet of Things in eHealth

A patient monitoring system for the Internet of Things in eHealth can be established through the integration of wireless body area network, communication infrastructure, and the hospital network. The dynamic and heterogeneous environment of the Internet of Things may facilitate the pa- tient with mobility options. However, security-related prob- lems may obstruct the development of such a comprehensive patient monitoring system. While assessing the security of a patient monitoring system, it is necessary to realise that it may not be enough to only look into the security related aspects of the body area network. Instead, the overall patient monitoring system should be treated as a connected and integrated eHealth system. This paper analyses the important security issues that can put the eHealth system at risk. The specific se- curity goals and requirements, vulnerabilities, threats, and attacks are analysed and some possible security recommenda- tions with direction for future work are discussed.
The role of bridging nodes in behavioral network models of complex engineered systems

Recent advances in early stage failure analysis approaches have introduced behavioral network analysis (BNA), which applies a network-based model of a complex engineered system to detect the system-level effect of ‘local’ failures of design variables and parameters. Previous work has shown that changes in microscale network metrics can signify system-level performance degradation. This article introduces a new insight into the influence of the community structure of the behavioral network on the failure tolerance of the system through the role of bridging nodes. Bridging nodes connect a community of nodes in a system to one or more nodes or communities outside of the community. In a study of forty systems, it is found that bridging nodes, under attack, are associated with significantly larger system-level behavioral degradation than non-bridging nodes. This finding indicates that the modularity of the behavioral network could be key to understanding the failure tolerance of the system and that parameters associated with bridging nodes between modules could play a vital role in system degradation.
Steady Stokes flow past dumbbell shaped axially symmetric body of revolution: An analytic approach

In this paper, the problem of steady Stokes flow past dumbbell-shaped axially symmetric isolated body of revolution about its axis of symmetry is considered by utilizing a method (Datta and Srivastava, 1999) based on body geometry under the restrictions of continuously turning tangent on the boundary. The relationship between drag and moment is established in transverse flow situation. The closed form expression of Stokes drag is then calculated for dumbbell-shaped body in terms of geometric parameters b, c, d and a with the aid of this linear relation and the formula of torque obtained by (Chwang and Wu, part 1, 1974) with the use of singularity distribution along axis of symmetry. Drag coefficient and moment coefficient are defined in various forms in terms of dumbbell parameters. Their numerical values are calculated and depicted in respective graphs and compared with some known values.
Syntactic Variation in Nigerian English and Students achievement in english language

-This paper examined the issue of syntactic variation in Nigerian English as it relates to students achievement in English language. Syntactic variation stems from the fact that no two languages are the same. The concept of Nigerian English was discussed. It was observed that when English language is not the mother tongue of the speakers who use it for communicative purpose, another variety is bound to emerge. Nigerian English has been described as being strikingly different from the standard British English variety. Characteristics of the Nigerian English were analyzed viz-a-viz the Standard British English. It was observed to be full of errors and variants. Students‟ achievement in English language over the years has been a cause of concern to not only the students‟ but to the generality of Nigerians. One may blame the failure on the interference of the mother tongue on the target language coupled with the insistence that English language exam should be marked based on the standard British English. Based on the above, one of the recommendations is that English language curriculum should be structured to include areas of syntactic variation in Nigerian English vizaviz the standard British English.
Nurturing eco-centric behaviour on campus: Barriers and motivators

In recent years, climate change and its impacts have taken centre-stage in the media as well as academic research. This has led to better awareness of the sustainability issue among the general public. However, studies have also shown that head knowledge is not necessarily matched by actual sustainable practice. The community plays an important role to effect lasting changes towards a more eco-centric behaviour. While research on this topic has been undertaken by various disciplines such as marketing and psychology, these have been done in isolation. The purpose of this paper is to draw together the knowledge from these well-established disciplines and identify the barriers and motivators to ecocentric behaviour. From here, a Six-P framework for nurturing eco-centric behaviours is developed. To illustrate the application of this framework, strategies adopted by green campus communities that reflect the Six-P framework are presented.
