Abstract:
This paper is a study on a modular smart plant factory integrating intelligent solar module, LED module with high efficiency for plant growth, IoT module control system and image processing technology. The intelligent sun and modules have a corrugated structure, and the angle of the module can be adjusted to obtain a large amount of power generation. It is fully foldable for wider angles during the day and module protection at night. The LED module is designed and manufactured to distribute energy evenly over the entire wavelength range so that high efficiency can be obtained. The control system with IoT convergence technology enables control of all parts related to plant growth such as angle control of solar modules, LED lighting control, temperature/humidity control, and fan control. In particular, the control method is programmed to be controlled by a computer monitoring system and a smartphone app, so there are few places. In addition, this paper developed an image processing algorithm to extract the growth information of lettuce grown in the plant factory. The acquired images were separated into R, G, and B images using Matlab software. The applied algorithms are k-mean and improved morphological image processing. By applying this method, we can determine the area calculation and shipping of lettuce seedlings. As a result of the fusion and application of solar modules, LED modules, and IoT modules, information on plant growth and status was confirmed.

Abstract:
Abstract To study the development trend of embedded platforms in home appliances Internet of Things (IoT), an application of embedded Linux in the design of IoT gateway is designed. ARM microprocessor S3C2410, EM310 radio frequency (RF) module, and Ethernet DM9000A module are used to realize the home network information-processing platform. The platform utilizes existing network facilities, RF modules, and network interface modules to realize the interconnection of the home perception network through wireless or wired links. For experimental analysis, Ping the central server (gateway) from the IoT node B is set to twice: The first time ttl = 255 time = 1.9 ms, the second time: ttl = 255 time = 2.4 ms. After application verification, the system has the characteristics of low cost, small size, low power consumption, and vital ease of use. It can not only integrate the home Internet and the IoT gateway but also directly run application-layer communication protocols such as HTTP/MQTT between IoT nodes and Internet terminals. The design supports multi-hop communication and significantly increases the deployment range of IoT nodes without signal relay equipment, hence reducing the cost of IoT networking and the complexity of the network architecture.

Abstract:
This paper proposes a novel design of application specific integrated circuit (ASIC) which is capable of connecting sensor network and other electronic systems to the Internet. The transfer of data between different networks and internet of things (IoT) platform is controlled by IoT platform with the help of instruction sent to ASIC. ASIC will act as serial peripheral interface (SPI) master to all connected networks and data will be transferred serially between them. The different ASIC modules are SPI module, control module, memory module and data/instruction decoder with additional modules built-in self-test (BIST) and direct memory access (DMA). The proposed ASIC will consume less power as compared to conventional microcontroller/microprocessor due to the fact that it is designed for IoT applications. It is described in VHDL at RTL level and simulation is done on the Vivado 2016.2.

Abstract:
In this paper, we develop an ontology-based framework for energy management in buildings. We divide the functional architecture of a building energy management system into three interconnected modules that include building management system (BMS), benchmarking (BMK), and evaluation & control (ENC) modules. The BMS module is responsible for measuring several useful environmental parameters, as well as real-time energy consumption of the building. The BMK module provides the necessary information required to understand the context and cause of building energy efficiency or inefficiency, and also the information which can further differentiate normal and abnormal energy consumption in different scenarios. The ENC module evaluates all the information coming from BMS and BMK modules, the information is contextualized, and finally the cause of energy inefficiency/abnormality and mitigating control actions are determined. Methodology to design appropriate ontology and inference rules for various modules is also discussed. With the help of actual data obtained from three different rooms in a commercial building in Singapore, a case study is developed to demonstrate the application and advantages of the proposed framework. By mitigating the appropriate cause of abnormal inefficiency, we can achieve 5.7%, 11.8% and 8.7% energy savings in Room 1, Room 2, and Room 3 respectively, while creating minimum inconvenience for the users.

Abstract:
electronic instruments and many other instruments which mostly depends on power. So the harvesting of power becomes necessary. In order to leave required amount of power to the next generation, we should harvest the power what we have now. In this project we used four modules for harvesting power. Extracting maximum power from a solar power harvester with minimum power transfer loss is the primary goal of this project. The proposed system demonstrates that we can track maximum power point tracking (MPPT) under rapidly changing atmospheric condition. Instead of photovoltaic cell, the solar cells are used for harvesting power. There are totally four modules used and these modules are controlled using a main board. The each power harvesting module consists of wireless transmitters which is controlled by IOT webpage. Also each power harvesting modules consists of wireless transmitter. These transmitters are used to transmit the power to the receiver through wireless networks. All these nodes are controlled using main board. This control board can be user configurable. The smart WSN controlled power harvesting system is also established here.

In the recent times of data transmission, applying the Internet of Things (IoT) device, networking to the various IoT modules is still a great challenge with the deployment stage. Very few localities in the world have the deployed IoT module integrated in its communication, but still maximum of the location are in testbed. As a practical application, the IoT modules can be used to collect the information about either the drunken person who is driving the vehicle or the heavily loaded vehicles. The vehicle that we are about to search should be integrated with the IoT module. In this paper, a novel approach for object tracking specifically the drunken driving person and the heavily loaded vehicle is proposed to ensure the follow of rules and prevent any mis happening. The task is to identify the exact vehicle which does not follow the rules which can be tracked and eliminated. For that we are proposing a simple methodology on identifying the vehicle by the tracking the locality of the vehicle as a cluster of nodes where the cluster provides the key inference on how the vehicles are interrelated in the learning environment.

Full text
Abstract:
Digital forensic investigation involves data acquisition from storage and memory devices including embedded memory, such as flash memory. In the age of IoT-connected systems, in which a typical crime scene often has several interconnected smart devices, chip-off analysis, the physical removal of a microchip from the circuitry for digital forensic acquisition, is time-consuming and can potentially lead to loss of data, even damage to the original memory chip involved in the alleged crime (due to the heat the chip is exposed to during the process). This study introduces a novel system-on-a-chip approach designed for rapid and non-intrusive data acquisition from IoT devices, addressing the limitations of traditional chip-off forensic techniques that often result in data loss and potential damage to memory chips. Utilizing a purpose-designed smart device, this method enables direct data retrieval from the microchip level, integrating seamlessly into a forensic toolkit to improve the speed and integrity of evidence gathering while maintaining the operational state of the device. The method places particular emphasis on physical data acquisition, essential for thorough analysis, including the recovery of deleted files and investigation of file tampering. The research develops a remote acquisition technique that accesses memory modules of diverse smart devices with minimal footprint, offering a device-agnostic solution that preserves data in its last functional state, thus enhancing evidence recovery. By ensuring the forensic soundness of the data extraction process, this innovative approach significantly advances digital forensics, enhancing both the integrity and admissibility of evidence in legal scenarios.

Abstract:
Avec le développement des applications mobiles (téléphonie, IoT, domotique, …), les systèmes embarqués ont montré une croissance exponentielle ces dernières années. Or la principale caractéristique de ces nouveaux systèmes est la combinaison d’une puissance de calcul importante avec une grande autonomie de fonctionnement. Malheureusement, ces caractéristiques étant diamétralement opposées, les concepteurs de systèmes se heurtent à un dilemme leur imposant de limiter la puissance embarquée. Afin de pallier ce problème d'autonomie, de plus en plus d'architectures se tournent vers la mise en place d'étages de récupération d'énergie depuis une ou plusieurs sources. Dans le cadre d'une thèse CIFRE, l'étude a ainsi été portée sur la conception d'un module de récupération d'énergie optimisé s'interfaçant sur plusieurs sources. Deux directions ont ainsi été trouvées afin d'augmenter la quantité récupérée par un tel dispositif :- Le développement de l'approche multisources afin de proposer une architecture industrialisable.- L'optimisation des quantités d'énergie extraites de chaque source par l'intermédiaire d'algorithmes nouvelle génération permettant la recherche du point de fonctionnement maximum. Ces derniers sont ainsi optimisés grâce aux progrès réalisés récemment dans le domaine du Deep Learning et la commercialisation de microcontrôleurs à faible puissance de plus en plus performants. L’objectif final étant de déployer des réseaux de capteurs à grande échelle et faible coût, dont l’autonomie est améliorée voire infinie si le système parvient à produire plus d’énergie que ce qu’il consomme<br>With the development of mobile applications, such as telecoms, IoT and home automation, embedded systems have shown an exponential growth over the past years. The main characteristic of these newly build systems is to combine high processing capabilities and extended operational autonomy. Unfortunately, these parameters are fundamentally opposed and hardware designer facing this issue by limiting processing capability to ensure enough autonomy. To solve this autonomy problem, newly architectures choose to implement an energy harvesting stage with one or more sources. As part of this industrial thesis, the study has been carried out on the design of an optimized energy harvesting module using one or more sources. Two directions were found to increase the quantity of harvested energy: - Interfacing multiple harvester from complementary source in an industrialized architecture - Optimization of produced energy from each source by using next-generation algorithms of Maximum Power Point Tracking. These algorithms are optimized thanks to technical advances made in the field of Deep Learning and the availability of more efficient low power microcontroller. The final goal of this study is to deploy a low cost wide area network of sensors with enhanced or infinite autonomy

Abstract:
In this thesis, a section of a lithium ion battery module, including five cells and an indirect liquid cooling system, was modelled in COMSOL Multiphysics 5.3a. The purpose of this study was to investigate the thermal properties of such a model, including heat generation per cell and temperature distribution. Additionally, the irreversible and reversible heat generation, the cell voltage and the internal resistance were investigated. The study also includes the relation between heat generation and C-­‐rates, and an evaluation of COMSOL Multiphysics 5.3a as a software. It was found that having liquid cooling is beneficial for the thermal management, as the coolant flow helps to transfer away the heat generated within the battery. The results also show that it is important to not go below a set cell voltage at which the cell is considered fully discharged. If a control mechanism to stop the battery is not implemented, the generated heat, and consequently the temperature, increase drastically. COMSOL Multiphysics 5.3a was considered a suitable software for the modelling. For future research it is of interest to expand the model to a full scale module to fully investigate the temperature distribution where more cells are being cooled by the same coolant loop.

Abstract:
Renewable Energies have the capability to cut down the severe impacts of energy and environmental crisis. Integrating renewable energy generation into the global energy system calls for state of the art energy storage technologies. The lithium-ion battery is introduced in this paper as a solution with a promising role in the storage sector on the grounds of high mass and volumetric energy density. Afterward, the advantages of proper thermal management, including thermal runaway prevention, optimum performance, durability, and temperature uniformity are described. In particular, this review detailedly compares the most frequently adopted battery thermal management solutions (BTMS) in the storage industry including direct and indirect liquid, air, phase-change material, and heating. In this work, four battery thermal management solutions are selected and analyzed using Computational Fluid Dynamic (CFD) simulations for accurate thermal modeling. The outcome of the simulations is compared using parameters e.g. temperature distribution in battery cells, battery module, and power consumption. Liquid cooling utilizing the direct contact higher cooling performance to the conventional air cooling methods. However, there exist some challenges being adopted in the market. Each of the methods proves to be favorable for a particular application and can be further optimized.<br>Integrering av förnybara energier i globala energisystem kräver enorma energilagrings teknologier. Litium jon batterier spelar en viktig roll inom denna sektor på grund av både hög vikt- och volymmässig energidensitet. Korrekt värmestyrning (Thermal management) är nödvändigt för litium jon batteriernas livslängd och operation. Dessa batterier fungerar bäst när de ligger inom intervallet 15–35 grader. dessutom har olika värmestyrsystem utvecklats för att säkerställa att batterierna arbetar optimalt i olika applikationer. I den här studien fem värmestyrningslösningar för batterier har väljas och analyseras med hjälp av beräkningsvätskedynamik (CFD) simulering. Resultaten av simuleringarna jämförs med olika parametrar som temperaturfördelning i battericeller, batterimoduler och strömförbrukning. Alla metoder visar sig vara användbara lämplig för viss tillämpning och kan vidare optimeras för detta ändamål.

Abstract:
Beams of polarized protons play an important part in the study of the spin dependence of the nuclear force by measuring the analyzing power in nuclear reactions. The source at iThemba LABS produces a beam of polarized protons that is pre-accelerated by an injector cyclotron (SPC2) to a energy of 8 MeV before acceleration by the main separated-sector cyclotron to 200 MeV for physics research. The polarized ion source is one of the two external ion sources of SPC2. Inside the ion source hydrogen molecules are dissociated into atoms in the dissociator and cooled to a temperature of approximately 30 K in the nozzle. The atoms are polarized by a pair of sextupole magnets and the nucleus is polarized by RF transitions between hyperfine levels in hydrogen atoms. The atoms are then ionized by electrons in the ionizer. The source has various sensitive devices, which influence beam intensity and polarization. Nitrogen gas is used to prevent recombination of atoms after dissociation. The amount of nitrogen and the temperature at which it is used plays a very important role in optimizing the beam current. The number of electrons released in the ionizer is influenced by the size and shape of the filament. Optimization of the source will ensure that beams of better quality (a better current and stability) are produced.

Abstract:
Abstract This is an introductory text on the theory of modules over rings or, equivalently, over algebras, addressed to beginning graduate students. It stresses the importance of the categorical perspective and the use of homological tools. Modules are studied both from a classical point of view and a categorical one. For this purpose, rudiments of category theory, homological algebra and representations of quivers are introduced and applied in the study of module categories. After introducing such fundamental tools as the Hom functor and the tensor product comes the study of projective, injective and flat modules. The classical results, such as the classification of modules over principal ideal domains, the Jordan-Hölder, Wedderburn-Artin, and Morita theorems, are proven, as well as the Eilenberg-Watts theorems. Radicals (of modules, algebras and categories) are thoroughly studied. Homological invariants, such as the extension and torsion modules or the homological dimensions are introduced using derived functors and are applied in module theory. The book stresses the construction and analysis of examples.

Abstract:
Researchers at the National Aeronautics and Space Administration (NASA) have conducted a series of module-level tests on electric Vertical Take-off and Landing (eVTOL) Energy Storage Systems (ESS) for the generation of dynamic impact data to support standards developments. The tests were conducted on zero-state-of-charge Electric Power Systems (EPS) Electric Propulsion Ion Core (EPIC) modules at the National Institute for Aviation Research (NIAR), utilizing the NIAR outdoor drop test setup and personnel. Four total tests were conducted. For each test, the module was dropped at a specific orientation from a height of 50 feet while connected to a guided trolley in order to assess the effects of a 50-foot drop test on the ESS. The test velocities ranged between 46.9 and 52.8 ft/s with impact angles ranging between a flat, zero-degree impact and 18 degrees. Data were recorded in the form of temperatures, cell-level voltage, module level acceleration and digital image correlation from the tests. Accelerations were in the range of 1,500 g for a few millisecond duration, which were indicative of a shock type loading condition. No modules entered thermal runaway, and post-test inspections revealed a variety of internal deformations and damage present in the various modules tested, with specific damage occurring for specific orientations. The modules were ranked according to a custom developed scoring rubric developed by utilizing the test and post-test inspection results. The results were compiled, reported, and will be used to guide future ESS testing. Part 1 discusses the loading environments in the modules, while Part 2 will discuss the deformation and damage in the modules.

Four total tests were conducted on modules oriented in four different orientations. During initial post-test inspections at the drop facility, it was observed that the modules experienced varying amounts of damage in various locations and forms. The damage was quantified to the maximum extent possible via photogrammetric methods such as digital image correlation and marker tracking. Post-test modules were then disassembled, and forensics were conducted, which involved inspections into various containment structures and the cells themselves. A scoring rubric was developed in order to utilize a common methodology to quantitatively assess the damage incurred into each module as way of determining the least and most amount of damage present. Results in the form of post-test inspections, digital image correlation deformations, and scoring rubric values will be all presented, along with proposed paths forward for future work.

Abstract:
"Embedded systems and the Internet of Things (IoT) enable new procedures, measurement and analysis methods in the field of biomedical systems. The measurement of data, based on electrocardiogram (ECG)-, electromyogram (EMG)- or electroneurogram (ENG)-signals, allows a multitude of new approaches in diagnosis, prevention or rehabilitation. As part of a project for ENG-based control of prostheses, a platform has been designed, called smart modular biosignal acquisition, identification and control system (SMoBAICS), that also uses IoT-devices. In this paper, different IoT-devices are presented and described. In the context of an analysis of use cases, it becomes clear that the platform represents a toolbox, which provides appropriate modules and module configurations for different requirements. The designed IoT-devices use standard interfaces in order to integrate a specific additional function into the system. In the focus are two microcontroller (mC)-devices with different characteristics and a front-end system that enables the connection of a variety of Force Sensing Resistor (FSR)-sensors. Based on this platform architecture, many applications were presented, and examples were given of how the required functionality for the corresponding application can be achieved with the help of these IoT-systems. This platform enables a fusion of the various sensor data with the objective of motion identification and prosthesis control based on this by reading out various data (forces, acceleration, ENG-data, etc.) and integrating identification algorithms."

Baumgartner, Franz, Cyril Allenspach, Ebrar Özkalay, et al. Performance of Partially Shaded PV Generators Operated by Optimized Power Electronics 2024. Edited by Ulrike Jahn. International Energy Agency Photovoltaic Power Systems Programme, 2024. https://doi.org/10.69766/leof5152.

Full text
Abstract:
Inhomogeneous shading on the PV generator leads to disproportionately high losses. As the potential of PV generation on roofs or façades is to be increasingly utilised in the coming decades, these cases will occur more frequently. The aim here is to provide an overview of the challenges and state-of-the-art technical solutions for partial shading. Current developments in PV engineering show that maximum performance lies in the combination between optimised module placement, the use of modules that are tolerant of shading and optimised power electronics. Shortly after the discovery of the solar cell, blocking or bypass diodes were used to solve the inhomogeneous currents of groups of solar cells arranged in series or parallel wiring. Even today, they are still the most efficient and robust solution for the majority of common shading PV applications. Due to the very high rated outputs of the solar modules and the presence of only three bypass diodes, high temperatures can occur on a locally shaded solar cell. This forces heat outputs of up to 200W or 100W in the butterfly module connection through the associated activated bypass diode, which must be dissipated by the most shaded cell. If additional small-area defects occur in this affected solar cell, hotspot peak temperatures can occur, which can lead to permanent damage to the module or the risk of fire. However, in order to prevent a third of the module output being lost in this case, four or more bypass diodes are now used in so-called shadow-tolerant PV modules. With a higher number of bypass diodes per module area, it is also possible to selectively bypass smaller, less efficient areas of the module, which leads to an increase in the module yield. The hotspot effects can also be comprehensively and robustly prevented by the small number of solar cells per bypass diode, provided the bypass diode is properly designed. The first manufacturers are beginning to place these shade-tolerant PV modules on the markets. Today, planners can also select different power electronics systems for the next step in system integration towards grid feed-in, i.e. the connection of the individual modules in the string. This is the classic series connection of all modules in the string to the input of the DC/AC string inverter (SINV), which leads to the highest yields for weak and medium shading. This applies, for example, to light shading with a chimney or a ventilation pipe, where no more than one tenth of the modules in the string are reached by the shade at the same time during the six hours around midday, even when using standard modules with only three bypass diodes. (see Table 1) With medium to heavy shading, the widely used DC/DC converters directly on the PV module (MLPE), often also called power optimisers, can be used profitably. However, the combination of shade-tolerant PV modules with conventional SINVs can often deliver comparable annual yields. However, if the optimisers are also used behind each module even with weak shading (allMLPE), they deliver less yield in total than the simple SINV, as their own DC/DC losses then have a negative impact compared to simple connectors. This only becomes apparent if the MLPE manufacturers' data sheet claims of 99% efficiency are not viable. The published measurements carried out in independent laboratories over the last four years are listed in this report, which suggest that losses are around 2% higher. As the differences in yield between the power electronics variants SINV and MLPE are usually less than four per cent in annual yield for light to medium shading, the above-mentioned real MLPE efficiency at the specific operating points plays the decisive role in planning the most efficient system. However, as the commercial PV software planning tools currently use these MLPE manufacturer specifications which are over estimated, no meaningful system comparison can be expected for these shading categories. In this report the results of annual simulations performed by some sophisticated simulation tools that take these real MLPE losses into account are discussed.

Abdolmaleki, Kourosh. PR-453-134504-R05 On Bottom Stability Upgrade - MS III. Pipeline Research Council International, Inc. (PRCI), 2021. http://dx.doi.org/10.55274/r0012195.

Full text
Abstract:
The extension of the PRCI on bottom stability (OBS) software's applicability to shallow water is assessed. Version 3 of the software has a limitation on water depth; only depths greater than 6 m (20 ft) are accepted. This limitation is likely related to the increasing inaccuracy of linear wave theory as the wave height to water depth ratio increases, as well as caution about breaking wave limits. The usage of linear wave theory inside the software can be categorized into two different types: � Linear regular waves - these are used in the Level 1 module to determine the motions of the water particles as part of the calculation of the hydrodynamic forces; � Linear irregular waves - these are present in the Level 2, Level 3 and ASM modules, where the surface wave energy spectra are converted to the near-seabed wave velocities through the use of a transfer function based on linear wave theory. It is noted that for irregular waves, all wave spectral formulations currently implemented in the OBS software, do not account for water depth. This document addresses the finite water depth and shallow water restrictions and presents a discussion and investigation in two categories: 1. The direct use of the linear theory to describe waves in the Level 1 calculation module; and 2. The direct use of linear spectral transfer functions in the Level 2, Level 3, and ASM modules. The scope of this activity is to prepare a solution for consideration by PRCI and implement the agreed course of action. The solution proposed will be based on the continued use of the linear wave theory. It is noted that higher order wave theories would be more appropriate for shallow water conditions, but due to the currently established methodology in the software, implementation of higher order wave theory is not included within this scope.

Full text
Abstract:
In 2020/21, a review was commissioned by Sheffield Hallam University’s Leadership Team into the Module Evaluation Questionnaire (MEQ) to find out what difference it was making and how the data was being used. A range of evidence was gathered and drawn upon for this mixed-methods evaluation, including: online focus groups and interviews with 60 module leaders across three colleges; an online reflective activity with teaching and learning (T&amp;L) portfolio leads from 10 departments; interviews with 19 student course representatives; monitoring data and other evidence; and findings from literature and research across the sector. The steady fall in response rates in recent years, not just when the delivery of MEQs changed from paper to online, had limited the use of the data and its ability to fulfil its intended purposes in relation to quality assurance and quality enhancement. The standardised design of the MEQ was seen as a factor that restricted its potential usefulness, with many module leaders and some T&amp;L portfolio leads and, to a lesser extent, students stating that the MEQ should be more reflective of the complexity of their modules. Relevant literature highlighted a range of factors that are helpful in promoting questionnaires to students, but the findings of this evaluation suggested that there was a limit to how much effect these practices had. Some practices were perceived to be harder to implement when teaching and learning was delivered predominantly in an online environment. According to module leaders, the switch to online delivery of MEQs a few years before made it harder to personalise and explain their purpose and value to students. Some student reps were motivated to take part in the MEQ process, but others were reluctant to engage. There is a need to strengthen evaluation capacity building at all levels, of which a key component is to provide more guidance about interpreting and analysing students’ responses, particularly when response rates are low. Recommendations are provided to address specific issues identified from the evaluation findings.

Abstract:
Resilient modulus (MR) is a key factor in the Mechanistic Empirical Pavement Design Guide (MEPDG) which was adopted by INDOT in January 2009. The resilient modulus can be determined in new pavement projects from subgrade soil samples collected at the site. However, for a pavement rehabilitation project, it becomes difficult to obtain soil information, and coring for samples may not be feasible because of traffic. The literature is rich with correlations between the MR of the subgrade obtained in the laboratory with that estimated from FWD tests in the field. However, the review conducted shows very contradictory and inconsistent findings, thus existing correlations seem to apply only to the cases investigated, i.e., they are ad hoc correlations and cannot be generalized. To improve the interpretation of the FWD data and enhance the reliability of the results in Indiana, FWD and GPR tests were performed at five different road construction projects at the same locations where soil samples were collected and tested in the laboratory for resilient modulus. The selected sites included roads with rigid pavement and treated subgrade and flexible pavement with untreated subgrade. The study showed that (1) FWD backcalculation is greatly affected by pavement thickness; (2) GPR can provide actual thicknesses and can identify discrepancies between as-built and design pavement thickness; (3) for flexible pavements, a one-to-one correlation exists between FWD modulus and laboratory resilient modulus values for untreated subgrade soils; (4) MODTAG or ELMOD codes can both be used to estimate the resilient modulus of the subgrade in flexible pavements; (5) for rigid pavements, results of FWD backcalculation analysis using ELMOD or MODTAG greatly overestimate the resilient modulus of the soil, with backcalculated moduli 1.3 to 6 times higher than laboratory results; (6) ELMOD is recommended for routine analysis of FWD data, while MODTAG is recommended for research or to evaluate the quality of the data, when needed.
