Automated Wheelchair for Physically Challenged with AIoT Modules

The possible Smart Wheel Chair and its components are discussed in this chapter, as well as the ways in which it incorporates the microcontroller device that enables widespread electric wheelchair manipulation using head movements. Digital and mechanical components are housed in the device. The Automated Wheel Chair (AWC) is a resource and assistance device for paraplegics. Humans with a higher degree of impairment, such as quadriplegics, may benefit greatly from the intended chair. Quadriplegics are men and women who, due to age or infection, are unable to move any of the body's organs save the head. The accelerometer records processing unit is used to create a revolutionary head motion popularity technique. This article also includes information about the Bluetooth device that is mounted on the wheel chair, as well as the accelerometer that powers the motors and controls the chair's actions inside the domestic environment. Our wheelchair focuses not only on the tool's movement but also on the health of the person who uses it. The method is entirely dependent on the Internet of Things, and sensors are used to detect the cardiac rate and blood oxygen levels. The ultrasonic sensors aid in the detection of impediments, allowing the chair to move in a more exact path. Other objectives of this chapter include elucidating the use of the Smart Wheel Chair (SWC) to protect disabled people from catastrophic pandemics like COVID-19 or to assist them in their treatment of any pandemic-causing sickness. The current project's purpose is to expand an automatic sensing wheelchair by including sensors into its components. Such features in chairs increase a challenged individual's independence while also allowing them to be monitored by their loved ones. Keywords— PIR, Thermometer, Alexa, Internet of Things, Ultrasonic sensor.
Improved equivalent circuit model of practical coupled‐cavity slow‐wave structures for TWTs

The existing equivalent circuit model of space‐harmonic coupled‐cavity slow‐wave structures was extended to model structures with double slots and tapered or step‐tapered ferrules. This model was validated by comparing its results for dispersion and total impedance characteristics of typical slow‐wave structures operating in S‐band, with those obtained by computer simulation using the 3D Maxwell equation solver MAFIA. * This model was also validated with the experimental results of a particular double‐slot structure at S‐band. © 2002 Wiley Periodicals, Inc.

A Novel Reconfigurable MB-OFDM UWB LNA Using Programmable Current Reuse

This paper presents a design of a reconfigurable low noise amplifier (LNA) for multiband orthogonal frequency division multiplexing (MB-OFDM) ultra wideband (UWB) receivers. The proposed design is divided into three stages; the first one is a common gate (CG) topology to provide the input matching over a wideband. The second stage is a programmable circuit to control the mode of operation. The third stage is a current reuse topology to improve the gain, flatness and consume lower power. The proposed LNA is designed using 0.18 μm CMOS technology. This LNA has been designed to operate in two subbands of MB-OFDM UWB, UWB mode-1 and mode-3, as a single or concurrent mode. The simulation results exhibit the power gain up to 17.35, 18, and 11 dB for mode-1, mode-3, and concurrent mode, respectively. The NF is 3.5, 3.9, and 6.5 and the input return loss is better than −12, −13.57, and −11 dB over mode-1, mode-3, and concurrent mode, respectively. This design consumes 4 mW supplied from 1.2 V.
INTRODUCING CULTURAL HERITAGE

Caves have fascinated all peoples. So they are often seen as places of spiritual importance, as a site of religious rituals, as a place of curiosity or a place of great beauty. So, in addition to their value as natural heritage and often of scientific importance, they have also been seen as cultural icons. In some cases, use of a cave as a sacred or other special place is inextricably related to the surrounding landscape and so falls into that group of heritage sites now known as cultural landscapes. At another level, some are places of great intensity, and our keynote speaker will discuss the very specific example of rock art.
State of Practice of Building Information Modeling in Mechanical and Electrical Construction Industries

AbstractThe North American construction industry has seen a decline in productivity for decades due to various reasons, including a lack of collaboration and the increase in the complexity of systems. These problems are most visible in labor-intensive trades, such as mechanical and electrical construction. Within the last decade, building information modeling (BIM) has emerged as a potential solution to these problems. This paper attempts to highlight the state of practice of BIM in the mechanical and electrical industries. By analyzing responses from an extensive survey and interview process, this paper reaches three key conclusions, namely, (1) 59% of mechanical and electrical contractors that use BIM have 3 years or less of BIM experience; (2) contractors should use one to three BIM staff members and add 1–2% of total project-cost estimates to account for BIM implementation; and (3) more than 70% of mechanical and electrical contractors that have used BIM agree that BIM reduces field conflicts and impr.
Natural Probiotics and Nanomaterials: A New Functional Food

Natural probiotics are functional foods with several biological properties and nutritional value inherent to their chemical composition and can play a potentially beneficial role in reducing the risk of chronic degenerative diseases. In order to improve the stability of these compounds, increase the encapsulating power, delay oxidation, increase their effectiveness, control their release and improve the bioavailability of their combination with nanomaterials is a potential tool in the food area enabling the development of new products with functional and nutraceutical characteristics. In addition, the study of nanomaterials in natural probiotics is rarely reported in the literature, being an area of paramount importance in the development of new functional foods. Therefore, in this chapter, a review of nano-materials’ use in natural probiotics will be addressed to specify their advantages and methodologies of preparation and characterization.

System-area operating margin assessment and security enhancement against voltage collapse

The (very) short term reactive power scheduling function, to be adopted by ENEL Spa, takes into account the voltage stability requirements in a preventive application of the security function. In this environment the procedure determines the voltage collapse distance of the global system and of the areas controlled by the secondary voltage regulation (SVR) both in short (24 hours ahead) and in a very short term (few hours or fractions of hour ahead). The procedure also schedules the control actions to be taken in emergency states in a preventive way. Area or system-wise indicators, based on nodal sensitivities and/or eigen (singular) value analysis, provide effective measures of the margins of the system with respect to the risk of voltage collapse and the related corrective actions. Applications of the procedure to the EHV network and to a subtransmission area of the ENEL system are presented in the paper.
Sample preparation considerations for surface and crystalline properties and ecotoxicity of bare and silica-coated magnetite nanoparticles

Magnetite (Fe3O4) nanoparticles (NPs) have widely used in various fields, including in medicine, due to their (super)paramagnetic properties. This requires a thorough evaluation of their possible hazardous effects. However, there is no standard procedure for the preparation of oxidation-prone NPs (such as magnetite) before subjecting them to biological assays. In this study we used Fe3O4 NPs (bare and silica-coated) as test samples to compare different preparation methods (ultrasound, centrifugation and filteration of NPs suspensions) based on X-ray and dynamic light scattering analysis and evaluation of microstructure and surface charge. After oxidation and functionalization, all samples retained their superparamagnetic behaviour. The toxicity of NP suspensions obtained by the methods described for Paramecium caudatum ciliates and Sinapis alba plants was evaluated.
Reducing EMC problems through an electrical/optical interconnection technology

A novel interconnection technology for printed circuit boards (PCBs) is proposed that has the potential to meet the high-performance requirements of future electronic equipment while at the same time, the electromagnetic compatibility (EMC) behavior will be improved significantly. The technology has a far-reaching compatibility with the existing printed circuit-board technology and the existing design and manufacturing processes of the electrical part do not need significant modifications. After a short description of the most important basic technologies for its realization, this paper focuses on a general approach for modeling the resulting hybrid electrical/optical interconnections containing integrated optical highly multimodal waveguides with manufacturing-caused rough surfaces. Especially the transient analysis is addressed in order to provide an efficient analysis methodology and algorithms for timing and signal integrity prediction necessary for designing and manufacturing high-speed electronic systems. The developed overall modeling strategy is explained and first available results are presented.
Real-time data processor for the COMPASS hyperspectral sensor system

The NVESD COMPASS instrument is an airborne dispersive hyperspectral imager that covers the VNIR through SWIR bands and incorporates a real-time data processing system. The processing system consists of a Data Processing Computer (DPC) and an Operator Display/Control Computer (ODC). The high-performance DPC executes real-time sensor calibration and multiple spectral detection algorithms on 13 G4-processors in a Race++ switched backplane. The DPC sends three-band pseudo-color hyperspectral data, high-resolution target chips, and GPS/INS data to the ODC. The ODC outputs a geo-registered display of HSI color imagery with detection cue overlays. The COMPASS detection algorithms, which are particularly well suited to CC&D targeting applications, include the SSRX spectral anomaly detector, the NFINDR/STD spectral unmixing-based anomaly detector, (3) a supervised spectral matched filter (SSMF), and (4) Healey's invariant subspace detector. The DPC airborne component is VME-based in a compact, ruggedized chassis. The COMPASS real-time processor is a second generation system based on NRL-sponsored WarHORSE demonstrations. This paper reviews the DPC system design, capabilities and performance.
Motion Control for Advanced Mechatronics

Motion control is now recognized as a key technology in mechatronics. The robustness of motion control will be represented as a function of stiffness and a basis for practical realization. Target of motion is parameterized by control stiffness which could be variable according to the task reference. However, the system robustness of motion always requires very high stiffness in the controller. The paper shows that control of acceleration realizes specified motion simultaneously with keeping the robustness very high. The acceleration is a bridge to connect such robustness and variable stiffness. For practical applications, a technique to estimate disturbance is introduced to make motion controller to be an acceleration controller. Motion control of flexible structure and identification of mechanical parameters are also described.
A Study on the Variation of Heating and Cooling Load According to the Use of Horizontal Shading and Venetian Blinds in Office Buildings in Korea

The construction industry has made considerable energy-saving efforts in buildings, and studies of energy-savings are ongoing. Shading is used to control the solar radiation transferred through windows. Many studies have examined the position and type of shading in different countries, but few have investigated the effects of shading installation in Korea. In this study, the case of the shading installation according to the standard of Korea, and variations of the heating and cooling load in the unit area on the performance of the windows were examined. This study compared the variations of the heating and cooling load in the case of horizontal shading and the changing position of venetian blinds. This study confirmed that horizontal shading longer than the standard length in Korea saved a maximum of 13% energy consumption. This study confirmed the point of change of energy consumption by the Solar Heat Gain Coefficient (SHGC) variations. The exterior venetian blinds and those between glazing were unaffected by the SHGC. On the other hand, in the case of a south facade, the interior venetian blinds resulted in 24% higher energy consumption than the installation of horizontal shading in case of Window to Wall Ratio (WWR): 80%, U-value: 2.1 and SHGC: 0.4.

Physicochemical, Sensory, and Microbial Characteristics of Kindirmou and Pendidam, Two Traditional Fermented Milks of Adamawa - Cameroon, as Affected by the Fermentation Vessels

Recent data show that the containers traditionally used for fermentation, due to their nature, exchange with the fermented product, the consequence being a modification of the physico-chemical, microbiological and organoleptic properties of these products. The objective of this work is to study the influence of the fermentation vessel on the sensory, physicochemical, and microbial properties of kindirmou and pendidam, two traditional fermented milks from Adamawa - Cameroon. To this end, a descriptive test was used to generate the sensory properties of fermented milks in different containers, followed by biochemical (pH, titratable acidity, protein, sugar content, and total phenolic compounds) and microbiological analyses (total aerobic mesophilic flora, coliforms, lactic acid bacteria, yeasts and molds). Regarding sensory evaluation, samples of kindirmou and pendidam fermented in calabashes have a higher general acceptability than those fermented in plastic buckets and enamel plates. The total mesophilic flora and total coliforms were higher than the norm (≥ 6log10) for kindirmou and pendidam regardless of the fermentation vessel. The absence of yeasts and molds is noted in the samples of kindirmou, while they are found at very high levels in the samples of pendidam fermented in the calabash and in the enamel plates ((≥ 6log10). Fecal coliforms are absent in samples of kindirmou and pendidam fermented in the calabash, while they are found in samples fermented in plastic buckets and enamel plates. On the physicochemical level, the results obtained showed that the kindirmou fermented in the calabash had the highest soluble protein content (1.47 ± 0.04 g / 100 mL of milk) than those fermented in plastic bucket and enamel plates. The phenolic compounds are present only in the samples of milk fermented in the calabash and the average contents are 93.41 ± 3.04 mg / 100 mL of milk for kindirmou and 111.20 ± 2.01 mg / 100 mL for pendidam. To conclude, kindirmou and pendidam fermented in calabashes exhibit the best sensory and physicochemical characteristics, and are rich in bioactive compounds than those fermented in plastic buckets and enamel plates.
Impedance formulas of RF patch resonators and antennas of cavity model using fringe extensions of patches from DC capacitors

Fringe field effect is equivalent to an extension in size of an RF patch, either as resonator or as antenna. A CAD formula for this extension is derived from DC capacitor and is shown to be applicable for all practical thickness and permittivity εr of the substrate. For example, for patch resonators of large εr and for patch antennas on thick substrate (h/λ0 < 0.23), the maximum errors in resonant frequencies are only 0.2% and 3%, respectively. The fringe extension through DC is understandable in physics from the point of view of the frequency invariance of fringe field with thin substrate asymptotically. © 2002 Wiley Periodicals, Inc.
