Abstract:
ABSTRACT The hybrid operating room can be defined as the combination of imaging system and operating table installed in an operating theater room for, e.g. use of an angiography imaging system and operation table in an operation theatre or use of an operating table in angiography room. Shorter patient recovery time, decreased length of stay, streamlined care delivery, improvement in cross-specialty communication, minimized risk for communication-related errors across clinical specialties and lower overall cost of care are some of the advantages of the hybrid operating room. Although no/limited data exists in the literature, the potential disadvantages of hybrid operating suite are cost, infection, prolonged anesthesia and radiation exposure. The primary components of a hybrid operating suite are an imaging system and imaging compatible operation table. Area required for hybrid operating suite varies from 80 to 150 m2. The most common configuration of hybrid operating suite includes a flat panel angiographic X-ray imaging system and surgical equipment for cardiac surgery.

Abstract:
The installation and operation of geothermal systems increased due to the expectation of good cooling and heating performance due to stable heat source temperatures. In actual geothermal system operations, heat source temperature rises or falls due to an imbalance of heating and cooling energy usage. Problems of source side temperature result in reduced geothermal system performance. The purpose of this study is to develop hybrid geothermal system operation technology to stabilize temperature and improve system performance by utilizing auxiliary heat source system. The auxiliary heat source system is operated by comparing the performance when operating the geothermal heat pump system alone and the performance when operating the hybrid geothermal heat pump system. The performance of a hybrid geothermal system is determined by the circulating water temperature of the geothermal system and the circulating water temperature of the auxiliary heat source system. Hybrid geothermal heat pump system performance is predicted through numerical analysis and collection of hybrid geothermal system performance data at various temperature ranges through field test. An operating method was developed using the predicted performance as the changeover operating point of the hybrid geothermal heat pump system. When applying the development and operation technology, it handled about 11% more load than the existing geothermal system operation. The addition of an auxiliary heat source increases the initial investment cost compared to the existing geothermal system, but decreases energy consumption, confirming that the initial investment cost of 15.3 years is recovered.

Abstract:
Purpose. Substantiation of peculiarities of modernization of a heavy-duty vehicle with a hybrid power transmission by using the formed set of analytical and technological solutions for power transmission under operating conditions. Methodology. For the developed functional model of a hybrid vehicle operation, the parameters of the functional model and its links are presented, the relationships between the elements are described, and the boundary conditions are formed. A combined series-parallel hybrid drive scheme has been used, as it has a higher efficiency compared to parallel and series ones. When operating in idle mode and low loads, the diesel generator set replenishes the energy reserve in the energy storage device and the vehicle is operated. To recharge the energy storage devices, it is possible to use the traction electric motor as a generator, and during operation it is used in the energy recovery mode during vehicle braking. An optimization mathematical model has been developed to determine the parameters of the power plant and energy storage device, taking into account operating conditions. A procedure has been developed along with, on its basis, a subroutine algorithm for calculating the required energy intensity of the energy storage device and the power of the vehicle’s power plant. An assessment of the modernization effectiveness of mining dump trucks by hybrid power transmission was made. Findings. A functional model of a hybrid vehicle operation under appropriate operating conditions has been developed, and the main parameters limitations of the state have been given. The corresponding procedures and algorithm for calculating the parameters of the energy storage device and the power unit were compiled and then were used in the corresponding computer calculation program. In the study on fuel efficiency, three BelAZ-7547 dump trucks were considered. The values of the kinetic energy configuration were determined with an increase in speed (acceleration) and with a decrease in speed (deceleration). An assessment of the upgrading effectiveness was made for mining trucks with hybrid power transmission. The payback period of the corresponding measures was 1.42 years. Originality. To determine the power storage and power unit parameters, a functional model of a hybrid vehicle operation and an optimization mathematical model for determining the parameters of the power plant and energy storage, taking into account operating conditions, have been developed. The substantiation of a complex of analytical and technological solutions for the power transmission of a hybrid mining dump truck under operating conditions has been carried out. Practical value. The results obtained are useful in the implementation of the modernization of heavy mining dump trucks with hybrid power transmission in the operating conditions.

Abstract:
This article presents a steady state thermodynamic model of a solid oxide fuel cell gas turbine hybrid cycle which developed by using a simulation software, MATLAB®. The hybrid model integrates a zero dimensional level SOFC model with gas turbine. The hybrid system was used to study the effects of some operation parameter such as SOFC operating temperature, and current density on the specific work output, electrical efficiency, and exergy efficiency of a generic hybrid cycle. The results show that if the SOFC operating temperature, the power output, electrical efficiency, and exergy efficiency increase. The electrical efficiency of the hybrid system increase from 62 to 68 , and the exergy efficiency of the hybrid system increases from 60 to 66 when the operation temperature increases from 600°C to 750°C at a current density of 6000 A cm2. On the other hand, the system efficiency and exergy decreases with an increase in the current density.

Abstract:
It is suggested that thermoelectric coolers designing should not be limited to the extreme modes of their operation. In some cases, it is convenient to use the so called hybrid modes --- a combination of the extreme mode of maximum coefficient of performance for large temperature differences and a general cooling mode for small ones. The proposed hybrid mode makes it possible to control the cooling capacity of the module and not to confine this value to that under the extreme operating conditions, the maximum coefficient of performance in particular. Keywords: Thermoelectric module, hybrid mode, cooling capacity per pellet.

Abstract:
The energy performances of the integrated thermal solar systems in the hybrid heating systems are influenced by several aspects like technology used and the way the collectors are placed, the type and technology of the heating storage, the operating temperatures in the hybrid system and last, but not least, the chosen control strategy. The operating regime of the thermal solar system characterized mainly by the thermal solar agent’s temperature and flow rate, as well as the corresponding control strategy, define the parametric framework of the system and impose its energy performances during operation. The optimized systemic variation of the temperatures and flow rates in both, the solar loop and the heating circuit, results in higher annual energy performances of the hybrid heating system. The present paper approaches the premises referring to the different operating regimes that characterize thermal solar systems in order to highlight and quantify their influence over the energy performances of the thermal system. In this respect, a set of computational operating simulations were carried out on the targeted system during one year of operation, in different configurations and operating regimes, for the energy assesment of the thermal system.

AbstractThis paper presents a miniature hybrid capsule robot for minimally invasive in-vivo interventions such as capsule endoscopy within the GI (gastrointestinal) tract. It proposes new modes of operation for the hybrid robot namely hybrid mode and anchoring mode. The hybrid mode assists the robot to open an occlusion or to widen a narrowing. The anchoring mode enables the robot to stay in a specific place overcoming external disturbances (e.g. peristalsis) for a better and prolonged observation. The modelling of the legged, hybrid and anchoring modes are presented and analysed. Simulation results show robot propulsions in various modes. The hybrid capsule robot consisting four operating modes is more effective for the locomotion and observation within GI tract when compared to the locomotion consisting a single mean of locomotion as the hybrid robot can switch among the operating modes to suit the situation/task.

Abstract:
L’utilisation de systèmes d’imagerie à rayons X lors de chirurgies mini-invasives expose patients et staff médical à des radiations ionisantes. Même si les doses absorbées peuvent être faibles, l’exposition chronique peut causer des effets nocifs (e.g. cancer). Dans cette thèse, nous proposons des nouvelles méthodes pour améliorer la sécurité vis-à-vis des radiations ionisantes en salle opératoire hybride dans deux directions complémentaires. Premièrement, nous présentons des approches pour rendre les cliniciens plus conscients des irradiations grâce à des visualisations par réalité augmentée. Deuxièmement, nous proposons une méthode d'optimisation pour suggérer une pose de l’imageur réduisant la dose au personnel et patient, tout en conservant la qualité de l’image. Pour rendre ces applications possibles, des nouvelles approches pour la perception de la salle grâce à des caméras RGBD et pour la simulation en temps-réel de la propagation et doses de radiation ont aussi été proposées<br>The use of X-ray imaging technologies during minimally-invasive procedures exposes both patients and medical staff to ionizing radiation. Even if the dose absorbed during a single procedure can be low, long-term exposure can lead to noxious effects (e.g. cancer). In this thesis, we therefore propose methods to improve the overall radiation safety in the hybrid operating room by acting in two complementary directions. First, we propose approaches to make clinicians more aware of exposure by providing in-situ visual feedback of the ongoing radiation dose by means of augmented reality. Second, we propose to act on the X-ray device positioning with an optimization approach for recommending an angulation reducing the dose deposited to both patient and staff, while maintaining the clinical quality of the outcome image. Both applications rely on approaches proposed to perceive the room using RGBD cameras and to simulate in real-time the propagation of radiation and the deposited dose

Abstract:
This thesis presents the findings of an investigation into hybrid mode feed horns for use in the next generation of reflector antennas for satellite communications at Ka- band. Within the thesis, general field theory is developed and subsequently applied to specific horn-types in an effort to understand and explore the limits of the bandwidth over which they can offer suitable radiation characteristics. Studies into the use of both corrugated and dielectric-loaded horns identify a shortfall in their performance, particularly in the context as feeds for elliptical reflector antennas at Ka-band, as a consequence of the sizeable frequency separation between the Transmit and Receive functions. The need to operate at two widely separated bands, with little concern for the performance at all frequencies in between, affords the opportunity to take advantage of two exclusive mechanisms to independently optimise the performance at two sub- bands, corresponding to the Transmit and Receive functions. The 'dual-band' concept is explored by extending the field theory developed earlier in the thesis, this being applied to a corrugated structure with secondary mechanism that takes effect once the performance as a consequence of the corrugations themselves begins to degrade. The theory is tested by way of a practical investigation comparing the measured performance of different horn types, including a novel horn borne out of the dual- band concept described above. This led to the need to develop, construct and evaluate a suitable anechoic chamber, the work associated with this also being included in the thesis as an appendix. The results are reviewed in the context of the Ka-band application against both RF and practical design goals with the conclusion that the novel dual-band horn offers superior performance with respect to the state-of-the-art.

Abstract:
This project considers the planning and scheduling of an operating theatre at a large Australian public hospital, with the aim of reducing the length of elective surgery waiting lists. Operating theatre planning and scheduling is performed using an integrated approach, where specialties, surgeons, and patients are scheduled simultaneously. Hyper and hybrid metaheuristic techniques are presented, as the case study instances are too difficult for commercial solvers. Results indicate that these methods can be implemented in real-life to improve surgical departments at public hospitals by reducing surgical overtime, increasing patient throughput, and increasing operating theatre utilisation.

Abstract:
Series hybrid electric vehicles have their wheels driven by an electric motor powered by a battery with an engine plant that cranks a generator unit to provide electric power to the battery and if necessary to the electric motor. They promise significant reductions in greenhouse gases without compromising driving performance. This year GM has launched the first mass produced series hybrid electric vehicle and other car manufacturer are to follow over the next decade. In recent years significant progress has been made in new battery techno logies, electric propulsion designs, and optimisation of power flow and control of the electric components to reduce the weight and cost. While these developments have been made successfully, little attention has been spent on improvement of the generator-set for series hybrid electric vehicles. Generally, a generator-set consists of a three-phase machine and a three-phase rectifier circuit. Conventional generator- sets suffer from significant voltage drops across the output of the rectifier circuit caused by current commutation, resulting from interaction between the machine inductances and the rectifier. Any voltage drop across the output of the rectifier circuit leads to an inefficient operation ofthe generator system. In this thesis, a new generator-set for the use in series hybrid electric vehicle applications is presented, whereby the voltage drop caused by commutation is eliminated. In a typical rectifier circuit the output voltage drop is proportional to the commutation time, which is a function of the value of the machine inductance. The novel topology operates in such a way that the commutation time becomes independent from the value of the machine inductance. This is achieved by eliminating the output de-link capacitors that are used in traditional rectifier circuits and transferring these capacitors within a new rectifier circuit. These embedded capacitors are charged and discharged simultaneously with two switches. The capacitors still have the function of electric storage but they also operate in resonance with the supply inductance.

Abstract:
Avec les avancées récentes en microélectronique, en traitement numérique et en technologie de communication, les noeuds de réseau de capteurs sans fil (noeud RCSF) deviennent de moins en moins encombrants et coûteux. De ce fait la technologie de RCSF est utilisée dans de larges domaines d’application. Comme les noeuds RCSF sont limités en taille et en coût, ils sont en général équipés d’un petit microcontrôleur de faible puissance de calcul et de mémoire etc. De plus ils sont alimentés par une batterie donc son énergie disponible est limitée. A cause de ces contraintes, la plateforme logicielle d’un RCSF doit consommer peu de mémoire, d’énergie, et doit être efficace en calcul. Toutes ces contraintes rendent les développements de logiciels dédiés au RCSF très compliqués. Aujourd’hui le développement d’un système d’exploitation dédié à la technologie RCSF est un sujet important. En effet avec un système d’exploitation efficient, les ressources matérielles d’une plateforme RCSF peuvent être utilisées efficacement. De plus, un ensemble de services système disponibles permet de simplifier le développement d’une application. Actuellement beaucoup de travaux de recherche ont été menés pour développer des systèmes d’exploitation pour le RCSF tels que TinyOS, Contiki, SOS, openWSN, mantisOS et simpleRTJ. Cependant plusieurs défis restent à relever dans le domaine de système d’exploitation pour le RCSF. Le premier des défis est le développement d’un système d’exploitation temps réel à faible empreinte mémoire dédié au RCSF. Le second défi est de développer un mécanisme permettant d’utiliser efficacement la mémoire et l’énergie disponible d’un RCSF. De plus, comment fournir un développement d’application pour le RCSF reste une question ouverte. Dans cette thèse, un nouveau système d’exploitation hybride, temps réel à énergie efficiente et à faible empreinte mémoire nommé MIROS dédié au RCSF a été développé. Dans MIROS, un ordonnanceur hybride a été adopté ; les deux ordonnanceurs évènementiel et multithread ont été implémentés. Avec cet ordonnanceur hybride, le nombre de threads de MIROS peut être diminué d’une façon importante. En conséquence, les avantages d’un système d’exploitation évènementiel qui consomme peu de ressource mémoire et la performance temps réel d’un système d’exploitation multithread ont été obtenues. De plus, l’allocation dynamique de la mémoire a été aussi réalisée dans MIROS. La technique d’allocation mémoire de MIROS permet l’augmentation de la zone mémoire allouée et le réassemblage des fragments de mémoire. De ce fait, l’allocation de mémoire de MIROS devient plus flexible et la ressource mémoire d’un noeud RCSF peut être utilisée efficacement. Comme l’énergie d’un noeud RCSF est une ressource à forte contrainte, le mécanisme de conservation d’énergie a été implanté dans MIROS. Contrairement aux autres systèmes d’exploitation pour RCSF où la conservation d’énergie a été prise en compte seulement en logiciel, dans MIROS la conservation d’énergie a été prise en compte à la fois en logiciel et en matériel. Enfin, pour fournir un environnement de développement convivial aux utilisateurs, un nouveau intergiciel nommé EMIDE a été développé et intégré dans MIROS. EMIDE permet le découplage d’une application de système. Donc le programme d’application est plus simple et la reprogrammation à distance est plus performante, car seulement les codes de l’application seront reprogrammés. Les évaluations de performance de MIROS montrent que MIROS est un système temps réel à faible empreinte mémoire et efficace pour son exécution. De ce fait, MIROS peut être utilisé dans plusieurs plateformes telles que BTnode, IMote, SenseNode, TelosB et T-Mote Sky. Enfin, MIROS peut être utilisé pour les plateformes RCSF à fortes contraintes de ressources<br>With the recent advances in microelectronic, computing and communication technologies, wireless sensor network (WSN) nodes have become physically smaller and more inexpensive. As a result, WSN technology has become increasingly popular in widespread application domains. Since WSN nodes are minimized in physical size and cost, they are mostly restricted to platform resources such as processor computation ability, memory resources and energy supply. The constrained platform resources and diverse application requirements make software development on the WSN platform complicated. On the one hand, the software running on the WSN platform should be small in the memory footprint, low in energy consumption and high in execution efficiency. On the other hand, the diverse application development requirements, such as the real-time guarantee and the high reprogramming performance, should be met by the WSN software. The operating system (OS) technology is significant for the WSN proliferation. An outstanding WSN OS can not only utilize the constrained WSN platform resources efficiently, but also serve the WSN applications soundly. Currently, a set of WSN OSes have been developed, such as the TinyOS, the Contiki, the SOS, the openWSN and the mantisOS. However, many OS development challenges still exist, such as the development of a WSN OS which is high in real-time performance yet low in memory footprint; the improvement of the utilization efficiency to the memory and energy resources on the WSN platforms, and the providing of a user-friendly application development environment to the WSN users. In this thesis, a new hybrid, real-time, energy-efficient, memory-efficient, fault-tolerant and user-friendly WSN OS MIROS is developed. MIROS uses the hybrid scheduling to combine the advantages of the event-driven system's low memory consumption and the multithreaded system's high real-time performance. By so doing, the real-time scheduling can be achieved on the severely resource-constrained WSN platforms. In addition to the hybrid scheduling, the dynamic memory allocators are also realized in MIROS. Differing from the other dynamic allocation approaches, the memory heap in MIROS can be extended and the memory fragments in the MIROS can be defragmented. As a result, MIROS allocators become flexible and the memory resources can be utilized more efficiently. Besides the above mechanisms, the energy conservation mechanism is also implemented in MIROS. Different from most other WSN OSes in which the energy resource is conserved only from the software aspect, the energy conservation in MIROS is achieved from both the software aspect and the multi-core hardware aspect. With this conservation mechanism, the energy cost reduced significantly, and the lifetime of the WSN nodes prolonged. Furthermore, MIROS implements the new middleware software EMIDE in order to provide a user-friendly application development environment to the WSN users. With EMIDE, the WSN application space can be decoupled from the low-level system space. Consequently, the application programming can be simplified as the users only need to focus on the application space. Moreover, the application reprogramming performance can be improved as only the application image other than the monolithic image needs to be updated during the reprogramming process. The performance evaluation works to the MIROS prove that MIROS is a real-time OS which has small memory footprint, low energy cost and high execution efficiency. Thus, it is suitable to be used on many WSN platforms including the BTnode, IMote, SenseNode, TelosB, T-Mote Sky, etc. The performance evaluation to EMIDE proves that EMIDE has less memory cost and low energy consumption. Moreover, it supports small-size application code. Therefore, it can be used on the high resource-constrained WSN platforms to provide a user-friendly development environment to the WSN users

Abstract:
The sustainable exploitation of energy and reduction of pollutant emissions are main concerns in our society. Driven by more stringent international standards, automobile manufacturers are developing new technologies such as the Hybrid Electric Vehicles (HEVs). These innovative systems combine the main benefits of traditional Internal Combustion Engines (ICEs) with those of Battery Electric Vehicles (BEVs), while overcoming their main drawbacks. HEVs can offer significant improvements in the efficiency of the propulsion system, but they also lead to higher complexities in the design and in the control. In order to exploit all the expected advantages, a dedicated optimization of the Hybrid Operating Strategy (HOS) is required. In this framework, simulation plays a key role in identifying the optimal HOS, where the primary design targets are the fuel economy, emission reduction and improvement in the vehicle performance (including acceleration, driving range, operational flexibility and noise). With such a perspective, a simulation study was performed involving the implementation, in Matlab environment, of zero-dimensional models of a Series Hybrid Electric Vehicle (SHEV) and a Parallel Hybrid Electric Vehicle (PHEV). As far as the hybrid operating strategy is concerned, three different approaches were investigated: _ A novel Benchmark Optimizer (BO), that determines the best possible operating strategy for the selected target, mission profile and powertrain design. The single solution is characterized by a vector, in which every scalar independently defines the mechanical power of the electric machine, for the PHEV, or the engine speed, for the SHEV, at each time step of the selected driving cycle _ A real-time optimizer based on the Minimization of the Total system Losses (TLM). It involves a vector-approach, in order to select, at each time step, the power split that guarantees the minimum system losses. It requires a reduced number of calibration parameters and, therefore, is computationally fast and adequate to work in real-world applications. Based on this technique, two different methodologies concerning the engine component are considered: the Total engine losses (TLM TOT) and the Recoverable (with respect to the optimal operating point) engine losses (TLM REC) _ A real-time optimizer based on the Total Load Switch Thresholds. It switches the operating mode depending on the load and speed signals. It involves a scalar-approach and requires a reduced number of calibration parameters. It is by far the method that requires the least computational effort In all the three cases, the numerical optimizer is based on Genetic Algorithm (GA) techniques. GAs are inspired by the mechanism of natural selection, in which better individuals are likely to be the winners in a competing environment. It is a statistical approach able to solve optimization problems whose objective function is non-continuous, non-differentiable, stochastic and highly non-linear. The study analyses the optimization of the well-to-wheel CO2 emissions of a Parallel and a Series Hybrid Electric Vehicles along the New European Driving Cycle (NEDC) and the Artemis Driving Cycles. In the case of the only compression ignition engine, also NOx emissions were considered as optimization criteria along the NEDC.

Abstract:
In the last decade the hybrid propulsion has been considering as a viable alternative of chemical energy conversion stored in propellants into kinetic energy. This energy is applied in propulsive systems of manned platforms, maneuvering procedures and even in the repositioning process of micro satellites. It presents attractive features and good balance between performance and environmental impact. Paraffin based grains are the hybrid solid fuels appointed as polymeric fuel substitute. The liquid layer formed on the burning surface ensures high regression rate when driven into the flame front. Paraffin grains allow raw material recovery and reduce the risk of explosion in the presence of erosive burning. The structure of the grain and the control of the liquefying burning surface layer depend on the additives concentration, such as carbon black, which are added to the fuel matrix during the production process. In the solid propellant paraffin based grain a cylindrical center port developed during the centrifugation tends to concentrate carbon black in the outer region of the grain. The influence of carbon black distribution and hardness gradient in paraffin based grain were evaluated in this work. Despite being a well-known material, scarce data on the relation of activation energy (Ea) of paraffin is available. In this work, the kinetic parameters (activation energy and pre-exponential factor) of microcrystalline 140/1450F paraffin have been raised through Thermo Gravimetric Analysis in conjunction with the Arrhenius kinetic mechanism, according to ASTM-E1461. The analysis indicated that the microcrystalline 140/1450F paraffin presents activation energy of 242 kJ.mol-1 and pre-exponential factor from 1.42x1020 min-1 to 2.90x1025 min-1. Ignition was achieved with a 50 W pyrotechnic igniter. Firing tests with 140/1450F paraffin as solid fuel and gaseous oxygen (GOX) as oxidizer were carry on at pressure above 3.8 MPa. The study suggests that multiple thin layers grain may generate burning surfaces with hardness and carbon black concentration almost constant. In this work combustion instability presented by rocket engine was calculated applying the frequency and boundary layer delay time relationship as proposed by Karabeyoglu. The frequency instability up to was evaluated using LabVIEW data acquisition system. In hybrid propulsion the carbon black has been playing a key role in the gas production process on the burning surface, the contribution of carbon black in the combustion instability suppression of hybrid propulsion system with paraffin-based propellant was evaluated. The results confirm the potential use of paraffin base propellant grains loaded with carbon black charge in hybrid propulsion. Paraffin propellants grains doped with carbon black (CB - from 2% to 8%) were burned on the rocket engine test workbench in the Aeronautical Engineering Laboratory / ITA. In the hybrid combustion performance evaluation based on conventional methods approach, it was applied graphical means to visualize the flow path results. Through the flow profile adjustment it was identified a global regression rates values near the practical grain consumption. The model represented graphically the relationships between oxidizer mass flow rate from with injection pressure from and it is recommended as a tool to help the hybrid propulsion performance assessment.

Abstract:
The monograph provides a comprehensive systematic study of the transpositional mechanism of modalation in the Russian language, the principles and patterns of its operation. The causes, prerequisites, signs, stages (stages) and the limit of transposition of linguistic units from verbs in predicative, semi-predicative and substantive forms; adjectives in full/short form and adverbs, including in the function of predicatives; prepositional and prepositional forms of nouns and pronouns into the interparticle semantic and syntactic category of introductory modal words and expressions. Using the methodology of oppositional analysis and indexing, the indices of transposition of words and word forms are calculated, explicating in typical contexts a particular stage of modalation and the degree of correspondence of their differential features to the characteristics of nuclear representatives of the initial and final links of the intercategory transposition. Special emphasis is placed on the study of syncretic (peripheral and hybrid) structures representing, in different combinatorics and proportions, signs of interacting parts of speech and interparticle categories of predicatives and introductory modal units during modalation, as well as when modalation is combined with other types of transposition — predication, adverbialization, particularization, conjunctionalization, interjection, etc. A system of criteria is proposed, It makes it possible to differentiate functional and functional-semantic homonyms, as well as peripheral and hybrid formations that demonstrate different stages of modalation (including when combined with other transpositional processes). An inventory of units of different partial affiliation has been compiled, demonstrating varying degrees of transposition into introductory modal words and expressions, as well as sometimes into predicatives, adverbs, particles, conjunctions, prepositions, interjections. It is intended for linguists: researchers, teachers of higher education, teachers of literature and students.

Abstract:
Recently, public policies of urban regeneration have intensified and multiplied. They are being promoted with the aim to start social and economic dynamics within the local context which is subject to intervention. From the empirical analysis, we realise that such activities are mainly implemented by three subjects or by mixed coalitions (public institutions, actors of the third sector and companies). Within them, each player is moved by a multiplicity of interests and goals that go beyond their own nature – public interest, market and mutualism – and tend to redefine themselves, thus becoming hybrid forms of production of value (social, economic, cultural). By studying a number Italian and Catalan cases, this essay deals with the theory that, under specific conditions and configurations, a collaborative direction – of organization, production and design – would give life to successful procedures, even without the identification of a one-best-way. The collaboration is not simply a choice of operation, but a real production method which mobilises social resources to create hybrid solutions – between state, market and society – to complex issues that could not be faced solely with the use of the rationale of action of one among the three actors. In this framework, the systems of relations and interactions between players and shared capital become an essential condition for the success of every initiative of urban redevelopment, or failure thereof. Such initiatives are brought to life by the strategic role of individuals who foster connections as well as the dissemination of non-redundant information between social networks, and collective and individual actors which would otherwise be separated and barely able to communicate and collaborate with each other. In addition to the functions carried out by knowledge brokers, that have been extensively described in organisational studies and economic sociology, the aforementioned figures act as real social enzymes, that is to say, they handle the available information and function as catalysts of social processes of production of knowledge. Moreover, they increase the reaction speed, working on mechanisms which control the spontaneity.

Abstract:
Double Planetary Gear (PG) power-split hybrid powertrains have been used in production vehicles from Toyota and General Motors. Some of the designs use clutches to achieve multiple operating modes to improve powertrain operation flexibility and efficiency at the expense of higher complexity. In this paper, an automatic modeling and screening process is developed, which enables exhaustively search through all designs with different configurations, clutch locations and operating modes. A case study was conducted based on the configuration used in the model year 2010 Prius and Camry hybrids. It was found that by adding clutches, fuel economy can be improved significantly for plug-in hybrid (charge depletion) operations.

[14:09] Agnes Cronholm The protection of civilians (PoC) is considered a key indicator of mission success in UN peacekeeping contexts and is also a major area of focus for AU peace support operations. However, despite their ongoing partnership in several mission contexts, the AU and UN are operating with distinct strategic and operational approaches to PoC, including varying degrees of emphasis on people-centred approaches to PoC. This paper examines some of the challenges that need to be addressed by the UN and AU to ensure that PoC adopts a more people-centred approach and that it is streamlined in future hybrid and parallel operation settings.

Full text
Abstract:
Humanitarian coordination as an area of scholarly research has grown exponentially over the past decade and can be considered “a well-established and mature topic” now (Jahre and Jensen, 2021, 586).The global humanitarian coordination architecture seems to have more backing in terms of resources and support as well as knowledge and experience, than ever before. Despite this, on the ground, the humanitarian relief system continues to face challenges in the increasingly difficult operating environments whether it is protracted conflicts or other emergency situations causing mass displacement of populations (Healy and Tiller, 2014, p.4). This rapid review explores the following questions: how (if at all), has the current system adapted to these highly restricted operating environments? More specifically, is the current cluster system still relevant in such cases or can it be adapted for better use? And is there evidence to support that area-based approaches might be better suited to conduct adequate humanitarian coordination and planning? The evidence gathered in this report is based on a mixture of academic, policy, and practitioner-based literature.

Full text
Abstract:
While direct electrification appears to provide the most cost-effective route to decarbonization of commercial vehicles, uptake may be constrained by critical metal supply. Additionally, it will be many years before hydrogen power becomes decarbonized or if it can ever compete economically with direct electrification. An electric road system (ERS) could offer a highly efficient and cost-effective route to direct electrification that would greatly reduce the volume of batteries required, but pilot schemes are urgently needed to provide concrete data on operating costs for different ERS technologies. Furthermore, if plug-in hybrid electric vehicles could obtain most of their power from an ERS, liquid biofuels and “electrofuels” may prove useful for occasional off-grid range extension. To achieve extremely long-range for operation in remote locations, liquid fuels remain the only viable option. Unsettled Issues Regarding Power Options for Decarbonized Commercial Vehicles discusses the analysis required to understand the lifecycle energy use for different power options for decarbonized commercial vehicles.
