Abstract:
DC-DC converters are electronic devices used to change DC electrical power efficiently from one voltage level to another. Complex systems like an industrial printer require accurate high voltage levels to let the print head nozzles spit out the ink in the proper way, according to the pattern to be printed. Creadigit, product of System S.p.a, is a high precision printing system used in decorations for ceramic products. It is actually powered by a couple of rack mounted AC-DC converters, which offer simple powering solution at low cost. Nevertheless, the total system efficiency can be sensibly increased with the introduction of a DC-DC Step UP converter in place of the AC-DC supply. This thesis is focused on the analysis, modeling, design and implementation of a Boost converter for such application. One project goal is to provide the converter the ability to digitally adjust the output voltage according to the requirements of each printing head, thus leading to a consistent power saving of the entire system. The work structure is so arranged: first of all, it is explained the architecture of the printing system and the inkjet printing mechanism so as to understand why high voltage supplies are required. Secondly, the power amplifier system is analyzed through simulation in LTSpice environment. During these simulations, there will be an analysis of potential power savings introduced by the adoption of the adjustable DC-DC converter. It follows the Boost converter theory, necessary to understand the operation of the key element of this project. Moreover, a detailed study of the complex world of capacitors is developed. In fact, the output capacitor selection is one of the trickiest part in the design of a switching DC-DC converter. In this thesis, a short theoretical study about EMC in SMPS converters is accompanied by simulations that could anticipate the results of in-field studies. In the end, some results of a first DC-DC converter prototype will be presented.

Abstract:
Among the many renewable energy sources, solar power is becoming one of the quickest to be adopted due to continuous technological progress and reductions in cost. Today's typical photovoltaic modules that are connected together in series and parallel to form strings and sub-arrays. Various distributed photovoltaic architectures are introduced in this thesis and DC-DC converters with maximum power point tracking are also introduced. Partial power processing is a technique to allow only a fraction of the power to be processed by the DC-DC converter, thereby reducing losses and improving efficiency. A new partial power isolated DC-DC converter is proposed in this thesis. The converter features maximum power point tracking and its controller selectively engages the buck portion or the boost portion or both in response to the maximum power point tracking input signal to achieve the desired output voltage and maximum power. With series connected DC-DC converters, each DC-DC converter carries an equal string current and adjusts its output voltage proportional to the available power of the connected photovoltaic module. The proposed topology allows each photovoltaic module to operate at its own maximum power point under varying or mismatched solar irradiance conditions, yet keep the total DC string voltage constant. The proposed circuit is verified using PLECS simulation software. In comparison to the existing circuit with partial power processing method, the proposed circuit overcomes the disadvantage that the output voltage can only be greater than the input voltage. With the two metal oxide semi-conductor field effect transistors added in series with the diodes in the secondary side of the transformer, the new circuit operates at a 100kHZ switching frequency and is able to perform both step up and step down modes with a properly designed control block. As a result, the circuit can convert a voltage from a PV panel that is higher or lower than the output to a regulated DC output voltage.

Abstract:
Energy harvesting systems are becoming an increasingly popular area for research as they present themselves as a clean, renewable source of energy. There are currently some key design issues facing the development of these energy harvesting systems. In particular, these harvesters often produce relatively low voltages compared to the requirements of the intended application. For example, scientific apparatus aboard orbital satellites require relatively high voltage levels for operation (kV) but are powered from solar panels providing substantially lower output voltages (24 V). In contrast, for low power energy harvesting, such as micro scale vibration energy harvesters, a harvested voltage level of ≈0.5V is often required to power a low power sensor circuit which requires 2-5V. Voltage multiplication is commonly achieved using charge pump multiplier circuits. However, these circuits are quite limited in both the range of multiplication (per unit area) and the maximum voltage level. This work aims to take advantage of a noticeable gap in the research field and is specifically targeted towards energy harvesting application areas. This thesis presents a comprehensive analysis of novel bi-stable and resonant MEMS voltage step-up converters. The operation is based on isolating the charge of a mechanically variable capacitor and varying the gap between the electrodes by an appropriate method of actuation force. As the electrode gap varies, so does the voltage level across the electrodes. In the case of the bi-stable devices, electrostatic actuation is employed while the resonant devices rely on ambient vibration force. These have been specifically designed for integration with static and vibration energy harvesters respectively. Prototype devices were fabricated using a dicing-free Silicon-on-Insulator (SOI) process developed at the Southampton Nanofabrication Centre. For the bi-stable device, a maximum output voltage of 35.7V was measured, using a 100MΩ load resistance, from a 24V input voltage. Further improvements in the design of the MEMS variable capacitor can be made in order to increase the capacitance level of the devices while reducing the parasitic fringing capacitance. Optimisation of the MEMS device would enable the output to reach a level near the theoretical maximum limit set at 120V.

Abstract:
The energy produced by the flow of water is known as hydropower. It is an easily accessible and available source of energy in large quantity in the form of, rivers, lakes, streams and runoffs around the world. Hydropower is dependent upon hydrological cycle hence; this beneficial characteristic of hydropower makes it a renewable source of energy. Hydropower is free from poisonous emission; therefore, it is considered as a safer and pollution free source of energy. It is usually used to develop electricity from generators. These generators are connected to the hydro turbines by means of shaft. The electricity produced from hydropower is stable and steady because of its higher capacity, thus it can be a suitable source to work as base-load and used to balance the power fluctuations caused by varying loads. The hydropower can also be accommodated with different sources such as solar and wind system. This way of power sharing needs quick regulation as the deviation in the power grid changes rapidly. To fulfil this power demand with higher stability prompted to the development of modern turbines with more efficient, reliable and robust design.   To achieve the above target, it is of prime importance to improve efficiency of hydro turbine. Nevertheless, many methods are in practice for improvement for efficiency of the turbine; though one of the prime elements which influence the turbine efficiency is surface roughness. The effect of surface roughness differs for different turbine components like stay vanes, guide vanes, runner, draft tube and spiral casing.   The main purpose of this thesis is to examine the effect of surface roughness for hydro turbine step-up efficiency. It is based on reduced scale model to prototype conversion method. For this purpose, IEC_62097 has provided an excel sheet as an attachment for calculation. There has been always a need to perform model test, since performing test on the prototype itself is very accurate, and calculations too, do not yield reliable results. Therefore, the model to prototype conversion method is considered a better solution.   A sensitivity analysis is conducted on a Kaplan turbine situated at the Granfors power station located along the Skellefteå river about 30 km from the city of Skellefteå. The results obtained after applying the latest step-up expressions are described and presented. These outcomes have shown significant positive impact on the hydro turbine efficiency improvement, which are presented in graphs.   The most significant variations of step-up efficiency against surface roughness were observed in the runner part of the turbine. This specific characteristic makes it evident that more focus and test should be conducted on this part to improve efficiency.

Abstract:
En aquesta tesis, es proposarà, com a solució per al disseny d’etapes d’elevat guany en aplicacions fotovoltaiques, la connexió en cascada d’elements canònics per al processat de potència basats en el convertidor elevador boost treballant sota un control en mode lliscant. Els tres elements canònics per al processat de potència són el transformador de corrent continu (CC), el girador de CC i el Loss-Free Resistor (LFR) o resistor lliure de pèrdues. La connexió en cascada de dos convertidors elevadors s’ha realitzat mitjançant diferents enfocs: dos elements canònics idèntics, dos elements canònics diferents i també mitjançant una única superfície de lliscament per controlar els dos convertidors. Les diferents connexions s’han comparat en termes de prestacions dinàmiques, estabilitat y temps d’establiment. Es podrà veure que la connexió en cascada de dos LFR és la millor opció per les aplicacions citades en termes de prestacions dinàmiques i estabilitat. La connexió en cascada de dos LFR s’aplicarà per la implementació d’una etapa d’adaptació d’impedàncies entre un generador fotovoltaic i un bus de tensió continua de 380 V. Per fer-ho s’utilitzarà un sistema MPPT basat en un algoritme de control extremal. Es modelarà la dinàmica ideal en mode lliscant d’ordre reduït a partir del model complet commutat tenint en compte les restriccions del mode lliscant, la característica no lineal del generador fotovoltaic i la dinàmica del control MPPT. A més a més, la connexió en cascada de dos LFR s’utilitzarà per inyectar la potència provinent d’un generador PV a una xarxa de corrent altern . A continuació, es durà a terme una comparació entre la connexió en cascada de dos LFR i dos convertidors amb guany elevat: el convertidor Z-source i un convertidor basat amb inductors acoblats. Aquests convertidors s’analitzaran per tal d’identificar els avantatges i els desavantatges de cada topologia en front a la connexió en cascada de dos LFR. La comparació es farà en termes de volum, nombre de components, prestacions dinàmiques, estabilitat i rendiment. Finalment, els dos LFR connectats en cascada s’utilitzaran per dissenyar una nanoxarxa formada per n LFR connectats en paral•lel que actuaran com etapa adaptadora entre n generadors fotovoltaics i un bus de CC de 380 V. Cada generador fotovoltaic es connectarà al bus de CC utilitzant dos LFR en cascada de forma que els n sistemes tindran els seus ports de sortida connectats en paral•lel. A més a més, es connectarà una bateria al sistema a través d’un convertidor bidireccional que serà l’encarregat de regular la tensió del bus de CC de la nanoxarxa. En el marc d’aquesta tesis s’han implementat diferents prototipus experimentals per tal de validar els anàlisis teòrics i les simulacions numèriques efectuades.

Además, la conexión en cascada de dos LFR se utilizará para inyectar la potencia proporcionada por un generador PV a una red de corriente alterna. A continuación, se llevará a cabo una comparación entre la conexión en cascada de dos LFR y dos convertidores con ganancia elevada: el convertidor Z-source y un convertidor basado en inductores acoplados. Estos convertidores se analizarán para identificar las ventajas y desventajas de cada topología frente a la conexión en cascada de dos LFR.

In this thesis, cascaded boost converters based on canonical elements under Sliding Mode Control (SMC) will be used as a solution for the high gain conversion ratio in PV applications. The three basic canonical elements for power processing are the DC-transformer, the DC-gyrator and the Loss Free resistor (LFR). Two cascaded boost converters will be synthesized based on one or two canonical elements using single or double sliding surfaces respectively. Different connections will be compared in terms of dynamic performance, stability, and settling time. It will be shown that the two cascaded LFRs is the best candidate for these kinds of applications in terms of dynamic performance and stability. The two cascaded LFRs will be applied to make an impedance matching between a PV generator and a DC voltage bus of 380 V. Maximum Power Point Tracker (MPPT) that employs an extremum-seeking control algorithm will be used. The ideal reduced-order sliding-mode dynamics model will be derived from the full-order switched model taking into account the sliding constraints, the nonlinear characteristic of the PV module and the dynamics of the MPPT controller. Moreover, the two cascaded LFRs will be used to connect a PV panel and AC distribution system. A comparison with other alternative converters for high gain conversion ratio will be carried out. The Z-source converter and the high step-up converter based on coupled-inductor are selected in order to make this comparison. These converters will be analyzed in order to address the advantages and disadvantages of each topology to be compared with the two cascaded LFRs in terms of volume, number of components, dynamic performance, stability and efficiency. Then, the two cascaded LFRs system will be used to synthesize a nanogrid consisting of n output paralleled two-stage boost converters which are used to connect n PV panels to a DC voltage bus of 380 V. Each PV panel is connected to the DC bus using two-stage cascaded LFRs and the n systems are connected in parallel at the output side which is then used as an interface between the panels and the DC grid. Moreover, a storage battery will be connected to the grid as a backup for the DC bus through a bidirectional converter and also for regulating the voltage of the DC bus. The thesis includes experimental implementations for validating the theoretical analysis and the numerical simulations.

Abstract:
Aim: The first customer is important because that it’s in many cases the only objective evidence that your product or service works in real life and that someone is willing to pay for it. The first customer is your first reference.   The aim of this study is to: Investigate how 7 start-up companies in the ICT-business developed reference. Establishing recommendations on what to focus on when creating reference customers. Present complementary recommendations for start-up companies regarding important factors, besides those investigated against the theory, which have been discovered to be important when building a successful company.   Method: The method in this study is a combination of a case study and cross-sectional study with qualitative data. The questions in the interviews were predefined and complemented with open ended questions according to the answers on the pre-defined questions. The data collected, the answers, were written down, summarized and analyzed regarding whether they did or did not support the theoretical statements investigated. A theoretical statement could be supported or not supported, partially or strongly   Result & Conclusions: The access to a professional network and good social skills are most important when establishing the first reference. Business skills can be developed during the process but the recommendation is to acquire or secure them as soon as possible. How to achieve the desired states has also been concluded.   Suggestions for future research: The largest limitation is the sample size of the data. Less than 10 companies were interviewed and some of the suggested statements can’t be significantly either confirmed or deferred. The study was also limited to one round of interviews. A study, with two rounds of interviews and a larger set of companies interviewed is suggested for further research. An extended study could also cover companies that didn’t survive the IT crash of 2000 and investigate if the suggested parameters and strategies were present and deployed or implemented.       Contribution of the thesis: The investigation has verified the importance of networks, customer type (brand name) and social capital when establishing a reference. It has also showed that the skills needed to develop a business doesn’t need to be present when company is established since it can be acquired and secured during the development of the first reference. It has also contributed with a set of recommendation for entrepreneurs in general not only regarding the establishment of reference customers where the most important recommendation is to build and maintain the personal and professional networks.

In clinical trials, multiple testing procedures can be conducted to classify the new treatment with respect to each of the k standard treatments. The regular assumptions of the multiple testing procedures are normality and homogeneous variance. The main purpose of this thesis is to release the assumptions and employ nonparametric test statistic in multiple testing procedures. The numerical example based on normality and homogeneous variance shows that the proposed nonparametric testing procedures and the multiple testing procedures using T test statistic reach the same conclusions. The simulation studies indicate that the proposed nonparametric testing procedures coincide the required condition FWE≦α , and also they have higher power than the multiple T testing procedures under heterogeneous variance.

Abstract:
The review is about textbook on television and radio communication for students, teachers of faculties and departments of journalism, as well as journalists-practitioners, prepared by the author’s team edited by Vasyl Lyzanchuk. Textbok absorbed some considerations and conclusions from previous theoretical developments, which found a new meaning here, deeper argumentation, supplemented by many interesting observations that correspond to the spirit of the time, the innovations that have appeared in recent years in the media space of Ukraine. The textbook has ten sections, each of which is designed to enrich the student with knowledge of television and radio communications, teach him or her all that a media professional should know and be able to apply it in practice. The titles of the sections indicate their practical orientation: «Basic methodical measures of functioning of information radio and television genres», «How we analyze, interpret, explain facts, events, phenomena», «Features of the creation of artistic programs on radio and television» and others. All sections of the textbook are meaningfully connected and constructed in such a way as to provide students with the opportunity to gradually, step by step to deepen their theoretical and practical knowledge of television and radio communications. This is undoubtedly the merit of the authors of the edition. The student will benefit from the numerous examples of television and radio materials prepared by the students themselves. Their creative work should convince that this work can serve as a stimulus for creative work for future journalists during their years of study. In addition to professional competence, as rightly emphasized in the textbook by Professor Vasyl Lyzanchuk, “It is very important to form in students, future journalists, socio-national competence, deep understanding of the essence of freedom of speech and responsibility for the content of the spoken word and image, to develop the belief that they are active participants in the Ukrainian state-building processes, and not intermediaries or repeaters of information”. It should be noted that the educational element is present throughout the textbook starting with the first chapter, historical (author Professor Ivan Krupskyi). While studying this textbook, students should realize that from the honor of journalists, their dignity, patriotism depends on the honor, authority, bright name of Ukraine, its future; that their assertion of Ukrainian national identity is the key to further prosperity of our state.

Full text
Abstract:
Because many patients reduce exercise following outpatient cardiac rehabilitation (CR), we developed an intervention to assist with the transition and evaluated its feasibility and preliminary efficacy using a one-group pretest–posttest design. Five CR patients were enrolled ~1 month prior to CR discharge and provided an activity tracker. Each week during CR they received a summary of their physical activity and steps. Following CR discharge, participants received an individualized report that included their physical activity and step history, information on specific features of the activity tracker, and encouraging messages from former CR patients for each of the next 6 weeks. Mixed model trajectory analyses were used to test the intervention effect separately for active minutes and steps modeling three study phases: pre-intervention (day activity tracking began to CR discharge), intervention (day following CR discharge to day when final report sent), and maintenance (day following the final report to ~1 month later). Activity tracking was successfully deployed and, with weekly reports following CR, may offset the usual decline in physical activity. When weekly reports ceased, a decline in steps/day occurred. A scaled-up intervention with a more rigorous study design with sufficient sample size can evaluate this approach further.

Allegretto, Sylvia A., and Dave Graham-Squire. Monopsony in Professional Labor Markets: Hospital System Concentration and Nurse Wages. Institute for New Economic Thinking Working Paper Series, January 2023. http://dx.doi.org/10.36687/inetwp197.

Full text
Abstract:
Rolling waves of consolidation have significantly decreased the number of hospital systems in the U.S. potentially affecting industry quality, prices, efficiency, wages and more. This research concerns the growth in hospital system consolidation in local labor markets and its effect on registered nurse wages. We first use a nonparametric preprocessing data step via matching methods to define MSA-specific samples of workers analogous to nurses outside of the hospital sector. This step enables an accounting of heterogeneous MSA-specific baseline wage growth, and yields a standardized measure of nurse wage growth across MSAs used to set up a multi-site quasi-experiment. We then run a parsimonious linear model; market size matters, for every 0.1 increase in consolidation in smaller-MSAs, real hourly nurse wage growth decreased by $0.70 (p-value of 0.038). Though not the primary aim of this study, a secondary finding is that real hourly wages for nurses grew less than that of comparable workers by $4.08.

Abstract:
The work proposes a conception of setup and use of teacher’s or lecturer’s workspace using common software and hardware products. The research object is a system built by using operating system capabilities in conjunction with office suite and public cloud service, as a foundation for teacher’s digital workspace. Research is made on how to set up, scale, and operate such a system, by studying the experience of national and foreign scientists and teachers, and using our own experience in educational processes, and working with operating systems and cloud services. As a result, we got a system which is easy to set up, learn, and apply by teachers without significant experience working remote education systems, and could be used for initial learning of remote education principles. It could be used as an initial step before migrating to specialized remote education systems. In the future, the system itself could be improved by adding additional objects into the system and a higher integration level between objects and external subjects.

Ostashev, Vladimir, Michael Muhlestein, and D. Wilson. Extra-wide-angle parabolic equations in motionless and moving media. Engineer Research and Development Center (U.S.), September 2021. http://dx.doi.org/10.21079/11681/42043.

Full text
Abstract:
Wide-angle parabolic equations (WAPEs) play an important role in physics. They are derived by an expansion of a square-root pseudo-differential operator in one-way wave equations, and then solved by finite-difference techniques. In the present paper, a different approach is suggested. The starting point is an extra-wide-angle parabolic equation (EWAPE) valid for small variations of the refractive index of a medium. This equation is written in an integral form, solved by a perturbation technique, and transformed to the spectral domain. The resulting split-step spectral algorithm for the EWAPE accounts for the propagation angles up to 90° with respect to the nominal direction. This EWAPE is also generalized to large variations in the refractive index. It is shown that WAPEs known in the literature are particular cases of the two EWAPEs. This provides an alternative derivation of the WAPEs, enables a better understanding of the underlying physics and ranges of their applicability, and opens an opportunity for innovative algorithms. Sound propagation in both motionless and moving media is considered. The split-step spectral algorithm is particularly useful in the latter case since complicated partial derivatives of the sound pressure and medium velocity reduce to wave vectors (essentially, propagation angles) in the spectral domain.

Baldwin, Gretchen. Considering the Future of Gender and Peace Operations: Strategic Debates and Operational Challenges. Stockholm International Peace Research Institute, December 2022. http://dx.doi.org/10.55163/lcsv1618.

Full text
Abstract:
The women, peace and security (WPS) agenda in peace operations has had myriad successes as well as setbacks in implementation. The rise of ‘gender-sensitive’ or ‘gender-responsive’ approaches to peacekeeping signals progress in policy language, but in practice, peacekeepers can struggle to comprehensively implement gender analyses or deliver on WPS tasks. Based on a review of existing academic and policy literature, this paper identifies five strategic debates central to WPS agenda implementation: participation beyond numbers, men’s roles, defining ‘gender’, balancing gender ‘inside and outside the fence’, and non-traditional security challenges. It then identifies six key operational challenges to implementation: resourcing, accountability, recruitment barriers, scale, siloing versus mainstreaming, and securitization. With the approach of the 25th anniversary of the WPS agenda in 2025—possibly the most significant yet for the integration of gender and peace operations—stakeholders should step up efforts to ensure the sustainability of the agenda’s implementation, in line with its most progressive reading.
