Hence, clients need to .
Carbon nanotube based battery architecture

We have fabricated batteries using a random network of carbon nanotubes serving both as the charge collector and the interface with the active components. Due to the high network conductivity and high porosity, such networks, in combination with nanoscale active components, lead to batteries with excellent energy storage characteristics. In addition the devices can be fabricated using a roll-to-roll or inkjet printing process, the essentials of what can be called “printed power. ”
Influence of attachment pressure and kinematic configuration on pHRI with wearable robots

The goal of this paper is to show the influence of exoskeleton attachment, such as the pressure on the fixation cuffs and alignment of the robot joint to the human joint, on subjective and objective performance metrics i.e. comfort, mental load, interface forces, tracking error and available workspace during a typical physical human-robot interaction pHRI experiment. A mathematical model of a single degree of freedom interaction between humans and a wearable robot is presented and used to explain the causes and characteristics of interface forces between the two. The pHRI model parameters real joint offsets, attachment stiffness are estimated from experimental interface force measurements acquired during tests with 14 subjects. Insights gained by the model allow optimisation of the exoskeleton kinematics. This paper shows that offsets of more than ±10 cm exist between human and robot axes of rotation, even if a well-designed exoskeleton is aligned properly before motion. Such offsets can create interface loads of up to 200 N and 1.5 Nm in the absence of actuation. The optimal attachment pressure is determined to be 20 mmHg and the attachment stiffness is about 300 N/m. Inclusion of passive compensation joints in the exoskeleton is shown to lower the interaction forces significantly, which enables a more ergonomic pHRI.
A Review to AC Modeling and Transfer Function of DC-DC Converters

In this paper, AC modeling and small signal transfer function for DC-DC converters are represented. The fundamentals governing the formulas are also reviewed. In DC-DC converters, the output voltage must be kept constant, regardless of changes in the input voltage or in the effective load resistance. Transfer function is the necessary knowledge to design a proper feedback control such as PID control to regulate the output voltage as linear PID and PI controllers are usually designed for DC-DC converters using standard frequency response techniques based on the small signal model of the converter.

COVID19 Outbreak: A Hierarchical Framework for User Sentiment Analysis

Social networking sites in the most modernized world are flooded with large data volumes. Extracting the sentiment polarity of important aspects is necessary;as it helps to determine people’s opinions through what they write. The Coronavirus pandemic has invaded the world and been given a mention in the social media on a large scale. In a very short period of time, tweets indicate unpredicted increase of coronavirus. They reflect people’s opinions and thoughts with regard to coronavirus and its impact on society. The research community has been interested in discovering the hidden relationships from short texts such as Twitter and Weiboa;due to their shortness and sparsity. In this paper, a hierarchical twitter sentiment model (HTSM) is proposed to show people’s opinions in short texts. The proposed HTSM has two main features as follows: constructing a hierarchical tree of important aspects from short texts without a predefined hierarchy depth and width, as well as analyzing the extracted opinions to discover the sentiment polarity on those important aspects by applying a valence aware dictionary for sentiment reasoner (VADER) sentiment analysis. The tweets for each extracted important aspect can be categorized as follows: strongly positive, positive, neutral, strongly negative, or negative. The quality of the proposed model is validated by applying it to a popular product and a widespread topic. The results show that the proposed model outperforms the state-of-the-art methods used in analyzing people’s opinions in short text effectively.
Unlawful Acts in Maritime Transport & Civil Aviation

Maritime and civil aviation security is a global problem posed by terrorism and illegal acts and therefore requires global attention and solutions that can only be provided by relevant international organizations (International Maritime Organization and International Civil Aviation Organization). Nineteen years have passed since the attacks of 11 September 2001 on the World Trade Center, but the threat of another terrorist attack is still just as possible and unacceptable. The series of attacks in the USA have started a new period of history. This period can be characterised as unsteady, unpredictable, and transforming of complex systems, including new types of dangers. The paper provides a comprehensive analysis and comparison of the most serious types of unlawful acts (terrorism and piracy) regarding legislation and jurisdiction. For the sake of comparability of legal phenomena, special attention is paid to illegal acts at sea and in the airspace above the sea.
Thermal issues in MEMS and microscale systems

Transduction mechanisms involving thermal phenomena play a central role in a wide range of microelectromechanical systems (MEMS) applications. An overview of a subset of thermal issues in MEMS technology is presented, including a discussion of traditional and emerging applications for microscale thermal systems. Issues relating to fundamental limitations and opportunities in thermal microsystems are presented. The use of thermal phenomena in three specific microsystems is reviewed, namely microhotplate chemical sensors, microfluidic systems, and electrothermal micromotors. Future directions in microscale and nanoscale thermal systems are presented.
The Role of Non-pharmacological Interventions on the Dynamics of Schistosomiasis

Schistosomiasis is a neglected tropical disease affecting communities surrounded by water bodies where fishing activities take place or people go to swim, wash and cultivate crops. It poses a great risk to the health and economic life of inhabitants of the area. This study was carried out to evaluate the impact of public health education and snail control measures on the incidence of schistosomiasis. A model was developed with attention given to the snail and human populations that are the hosts of the cercariae and miracidia respectively. The existence and stability of disease-free and endemic equilibrium states were established. The disease-free and endemic equilibrium states were shown to be locally asymptotically stable whenever the basic reproduction number was less than unity. Numerical simulations of the model were carried out to evaluate the impact of interventions (public health education and snail control measures) on schistosomiasis transmission. It was observed that the implementation of low coverage snail control with highly efficacious molluscicide and massive public health education will make the basic reproduction number smaller than unity, which implies the eradication of schistosomiasis in the population.
On Technology as Material in Design

And what is the purpose of writing music? One is, of course, not dealing with purposes but dealing with sounds. John Cage Silence In many ways, design has been moving away from the physical object. Emerging practices such as interaction, experience and service design, often utilising new technologies with almost 'immaterial' properties, seem to point to a situation where the material 'thing' as we used to know it is replaced by communication, information, systems and infrastructures. From another perspective, however, the importance of the things themselves is being re-discovered, and perhaps these new 'immaterial' technologies play a role in this. A central reason for this shift is that though technical objects are often characterised by their practical functionality, their everyday lives seem a bit more complicated than these official functions might suggest. Thus, the predominant focus on practical functionality in the design of technical objects need to reconsidered and above all complemented. As we turn to these things, we do not only have to re-locate the functions of technical objects within a rich context of use; to understand the presence of technical objects, we also need to consider the materials that build them. In what follows, I will present some ideas on how the properties of technologies (such as information technology) seem to influence the way we think about the design of technical objects. Further, I will try to challenge the instrumental perspective on technology by considering it to be design material, asking question about it such as: what are its expressions as material? What are its form elements?
Survey of reconfigurable architectures for multimedia applications

In a short period of time, the multimedia sector has quickly progressed trying to overcome the exigencies of the customers in terms of transfer speeds, storage memory, image quality, and functionalities. In order to cope with this stringent situation, different hardware devices have been developed as possible choices. Despite of the fact that not every device is apt for implementing the high computational demands associated to multimedia applications; reconfigurable architectures appear as ideal candidates to achieve these necessities. As a direct consequence, worldwide universities and industries have incremented their research activity into this area, generating an important know-how base. In order to sort all the information generated about this issue, this paper reviews the most recent reconfigurable architectures for multimedia applications. As a result, this paper establishes the benefits and drawbacks of the different dynamically reconfigurable architectures for multimedia applications according to their system-level design.
Control policy simulation based on machine age in a failure prone one-machine, one-product manufacturing system

This paper deals with the production planning problem of a flexible manufacturing system (FMS). This problem is within the class of problems which are usually faced during the life cycle of FMS. There are basically two approaches used to solve this problem: analytical and simulation. The objective of this paper is to develop a methodology for determine the control policy for a given FMS by using the combination of both analytical and simulation approaches. The production rate control of a one-machine one-product system is presented to illustrate our approach. The contribution of the analytical part of the proposed model consists of generating a near-optimal controller based on the concept of an age-dependent hedging point policy. This sub-optimal policy is used as input of the simulation part and the improvement of operating conditions (control policies) achieved with a constant demand rate. The proposed model includes also a stochastic demand and lot sizes in production which consists of similar products.
Indian diabetes risk profile of employees in a tertiary care facility in north Maharashtra: a cross sectional study

Background: The rising prevalence of type 2 diabetes (T2D) in India calls for screening of at-risk adults. Objectives were to assess IDRS (Indian diabetes risk score) of T2D in staff in tertiary care hospital, and to assess covariates random blood sugar (RBS), BMI, skinfold thickness (SFT), pre-existing T2D in the employees.Methods: In this cross sectional study, IDRS was used to assess all staff in a tertiary care institute. Anthropometric measurements, BP and RBS were done. Information on parental T2D, cereal intake and weekly physical activity (PA) was obtained in interview.Results: 370 subjects (F-117, M-273) with mean age 30.81 (7.99), BMI 22.89 (14.13) years were screened. Subjects in moderate and sedentary work were 185 each, 15% women and 39% men had higher waist size. Total 5.4% subjects had T2D including known diabetics. RBS in women and men was 113.1 (27.87), 114.7 (27.66), with IDRS score high in 29 (7.84%) and moderate in 144 (38.92%). Parental T2D was present in 19.5% subjects. IDRS risk was strongly associated with type of work (Chi-square 79.0283, df=4, p=0.00). Multiple logistic regression for IDRS risk outcome showed association of age (OR 1.4), BMI (OR1.3), parental T2D (OR 9.6) with highly significant p values. Multiple linear regression for RBS outcome was associated with age (OR 1.3) and BMI (OR 1.4) but the results were statistically not significant.Conclusions: Pooled IDRS risk was present in 47% subjects despite younger age of study population. Improvements in physical activity and reduction in waist size is the need of the hour.
Design and Optimization of New Compact Tunable 2.4‐GHz Band Pass Filter Using Coupled λ/2 Microstrip Open‐Loop Resonators and Mems‐Switch Technique

A new compact WLAN‐band pass filters are proposed using a half wavelength microstrip open‐loop and λ/2 microstrip resonators based on direct‐cross coupling method and micro electronic mechanical system (MEMS) technology. The filter is not only compact in size due to the slow‐wave effect, but also has multitransmission zeros at both low and high rejection bands, as well as low insertion loss in the pass band. A demonstration filter has been designed and tested. Simulation results almost agree with the measured results. Some discrepancy between them can still be observed, which can be attributed to the unexpected tolerance of fabrication. Due to the simplicity of the design and its fabrication, it shows that this type of band pass filter has great potential for actual applications in communication and other systems. By applying the MEMS technology, a switchable band pass filter based on the quadruplet filter is able to be designed. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2444–2450, 2013
XV. Account of the changes that have happened, during the last twenty-five years, in the relative situation of double-stars; with an investigation of the cause to which they are owing

In the Remarks on the Construction of the Heavens, contained in my last Paper on this subject, I have divided the various objects which astronomy has hitherto brought to our view, into twelve classes. The first comprehends insulated stars. As the solar system presents us with all the particulars that may be known, respecting the arrangement of the various subordinate celestial bodies that are under the influence of stars which I have called insulated, such as planets and satellites, asteroids and comets, I shall here say but little on that subject. It will, however, not be amiss to remark, that the late addition of two new celestial bodies, has undoubtedly enlarged our knowledge of the construction of the system of insulated stars. Whatever may be the nature of these two new bodies, we know that they move in regular elliptical orbits round the sun. It is not in the least material whether we call them asteroids, as I have proposed; or planetoids, as an eminent astronomer, in a letter to me, suggested; or whether we admit them at once into the class of our old seven large planets. In the latter case, however, we must recollect, that if we would speak with precision, they should be called very small, and exzodiacal; for, the great inclination of the orbit of one of them to the ecliptic, amounting to 35 degrees, is certainly remarkable. That of the other is also considerable; its latitude, the last time I saw it, being more than 15 degrees north. These circumstances, added to their smallness, show that there exists a greater variety of arrangement and size among the bodies which our sun holds in subordination, than we had formerly been acquainted with, and extend our knowledge of the construction of the solar, or insulated sidereal system. It will not be required that I should add any thing farther on the subject of this first article of my classification; I may therefore immediately go to the second, which treats of binary sidereal systems, or real double stars.
Summary of the Preliminary Optical ICHMI Design Study: A Preliminary Engineering Design Study for a Standpipe Viewport

This summary report examines an in-vessel optical access concept intended to support standoff optical instrumentation, control and human-machine interface (ICHMI) systems for future advanced small modular reactor (AdvSMR) applications. Optical-based measurement and sensing systems for AdvSMR applications have several key benefits over traditional instrumentation and control systems used to monitor reactor process parameters, such as temperature, flow rate, pressure, and coolant chemistry (Anheier et al. 2013). Direct and continuous visualization of the in-vessel components can be maintained using external cameras. Many optical sensing techniques can be performed remotely using open optical beam path configurations. Not only are in-vessel cables eliminated by these configurations, but also sensitive optical monitoring components (e.g., electronics, lasers, detectors, and cameras) can be placed outside the reactor vessel in the instrument vault, containment building, or other locations where temperatures and radiation levels are much lower. However, the extreme AdvSMR environment present challenges for optical access designs and optical materials. Optical access is not provided in any commercial nuclear power plant or featured in any reactor design, although successful implementation of optical access has been demonstrated in test reactors (Arkani and Gharib 2009). This report outlines the key engineering considerations for an AdvSMR optical access concept. Strictmore » American Society of Mechanical Engineers (ASME) construction codes must be followed for any U.S. nuclear facility component (ASME 2013); however, the scope of this study is to evaluate the preliminary engineering issues for this concept, rather than developing a nuclear-qualified design. In addition, this study does not consider accident design requirements. In-vessel optical access using a standpipe viewport concept serves as a test case to explore the engineering challenges and performance requirements for sodium fast reactor (SFR) and high-temperature gas reactor (HTGR) AdvSMR applications. The expected environmental conditions for deployment are reviewed for both AdvSMR designs. Optical and mechanical materials that maximize component lifetime are evaluated for the standpipe viewport design under these conditions. Optical components and opto-mechanical designs that provide robust optical-to-metal seals and stress-free optical component mounting are identified, and then key performance specifications are developed for a sapphire optical viewport concept. Design strategies are examined that protect the internal optical surfaces from liquid-coolant condensation and impurity deposits. Finally, a conceptual standpipe viewport design that is suggestive of how this concept could be assembled using standard nuclear-qualified pipe components, is presented. « less
Online Monitoring ICE Powers Based on the Crankshaft Angular Vibration

A new method of online monitoring ICE powers based on the crankshaft angular vibration is proposed. It has deduced that when each cylinder works uniformly at a certain rotating speed, and the vth order angular vibration mode of crankshaft nears plane vibration mode such as “quasi-rigid body model” or “quasi-trapeziform model”, so a cubic polynomial can represent the relationship between the vth order angular vibration displacement amplitude of the crankshaft reference point and the engine powers, thereby the angular vibration of reference point could be used to online monitor engine powers. Through the simulation and experimental researches on a 6240 and a 4100 diesel engine, it shows that the engine powers fitted with the angular vibration displacement amplitudes of reference point are close to the measured or theoretical powers comparatively, and the maximum errors is only 2.95%, which verifies the feasibility and practicability of the method consequently.
