The high penetration level of solar photovoltaic (SPV) generation systems imposes a major challenge to the secure operation of power systems. SPV generation systems are connected to the power grid via power converters. During a fault on the grid side; overvoltage can occur at the direct current link (DCL) due to the power imbalance between the SPV and the grid sides. Subsequently; the SPV inverter is disconnected; which reduces the grid reliability. DC-link voltage control is an important task during low voltage ride-through (LVRT) for SPV generation systems. By properly controlling the power converters; we can enhance the LVRT capability of a grid-connected SPV system according to the grid code (GC) requirements. This study proposes a novel DCL voltage control scheme for a DC–DC converter to enhance the LVRT capability of the two-stage grid-connected SPV system. The control scheme includes a “control without maximum power point tracking (MPPT)” controller; which is activated when the DCL voltage exceeds its nominal value; otherwise, the MPPT control is activated. Compared to the existing LVRT schemes the proposed method is economical as it is achieved by connecting the proposed controller to the existing MPPT controller without additional hardware or changes in the software. In this approach, although the SPV system will not operate at the maximum power point and the inverter will not face any over current challenge it can still provide reactive power support in response to a grid fault. A comprehensive simulation was carried out to verify the effectiveness of the proposed control scheme for enhancing the LVRT capability and stability margin of an interconnected SPV generation system under symmetrical and asymmetrical grid faults.

During positive pressure mechanical ventilation, percentile systolic pressure variation (%SPV) or respiratory-related arterial pressure variability (RAPV) have both been used in assessment of graded haemorrhage. We aimed to investigate whether changes in %SPV and RAPV are correlated during graded haemorrhage (by 5, 10 or 20% of the estimated blood volume) in anaesthetized positive pressure ventilated rats and to investigate the involvement of autonomic regulation. Saline vehicle or atropine produced no discernible effect on baseline %SPV or RAPV but, thereafter, %SPV and RAPV increased progressively with graded haemorrhage. Propranolol significantly decreased baseline %SPV and RAPV and changes induced in %SPV and RAPV by graded haemorrhage. Phentolamine significantly enhanced baseline %SPV and RAPV, and further enhancement of %SPV and RAPV by graded haemorrhage did not occur until 20% of the estimated blood volume was removed. RAPV was significantly correlated with %SPV in all experimental groups. We conclude that RAPV is comparable with%SPV as an indicator of graded haemorrhage and that, in anaesthetized and positive pressure ventilated rats, both are dependent on autonomic function, especially β-adrenoceptors.

Abstract One of the key reasons contributing to a reduction in the performance of a solar photovoltaic (SPV) system is the presence of partial shade on the solar panels. It is necessary to use maximum power point tracking (MPPT) in SPV systems to get around the non-linear behaviour of photovoltaic panels. This research analyses the reduction in power output of SPV systems caused by partial shading. In the latter part of the paper, the improved dynamic behaviour-based ant colony optimization MPPT approach under the effect of module-level partial shading is implemented in MATLAB®/Simulink®. Various partial shading levels were applied to SPV modules to evaluate the system performance. The proposed system follows the maximum power point with 99.9% accuracy and a response time of 2 ms. The addition of a weight coefficient accelerates the convergence of the algorithm.

Solar photovoltaic (SPV) panels that convert light energy into electrical energy through the photovoltaic effect have nonlinear internal resistance. Hence, with the variation in the intensity of light falling on the panel, the internal resistance varies. For effective utilization of the SPV panel, it is necessary to extract the maximum power from it. For maximum power extraction from SPV panels, DC-DC converter interface is used. The problem in using high frequency converter interface is the resultant high frequency ripple interaction with the SPV system. In this work, an interleaved boost converter (IBC) is considered to reduce the ripple. Our finding is that IBC fed by a SPV panel reduces this ripple to a greater extent. IBC also has a faster transient response as compared to conventional boost converters with reduced ripple contents. The main aim of this paper is to present a comparative analysis of the performance of IBC with inductors that are coupled in different ways. The results of the simulation were extrapolated with the help of MATLAB software and verified through experimentation.

AbstractA repeat of the seminal 1973 study on static positional nystagmus (PN) using more accurate recording techniques.The purpose was to further characterize PN and, using current data, introduce new clinical criteria for its identification.Static PN was recorded in ten positions with vision denied. Each position was analyzed using age, gender, presence, direction, and persistence of nystagmus while taking into account the number of beats and mean slow-phase velocity (SPV).One hundred healthy patients who were asymptomatic with no known neurological disorders were tested.No intervention was used.Analysis of variance, descriptive statistics, and confidence intervals were used to describe results.Results showed 74% of normal participants had horizontal nystagmus in at least one position. Only 7% of the observed nystagmus was persistent. The average SPV was 2°/sec. The mean number of positions in which nystagmus was observed was three. Neither age nor gender influenced the occurrence of nystagmus. Forty-three percent of the participants had vertical nystagmus in at least one position; however, the SPV was 2°/sec or less.The present study demonstrated that intermittent or persistent PN in four or fewer positions should not be considered pathological when the SPV is 4°/sec or less (n = 100). Observance of vertical nystagmus in one position should not be considered pathological if the SPV is 2°/sec or less. Suggested positions for positional testing should include seated-upright, supine, head right, head left, head-hanging, and the precaloric (30° supine) positions. Fixation when PN is observed is indicated.

This paper proposes a Solar Photovoltaic (SPV) interfaced Impedance Source Inverter (ZSI) based shunt Active Power Filter (APF) for compensation of power quality events such as current harmonics, voltage interruption and reactive power burden. The instantaneous reactive power theories with Fuzzy Logic Controller (FLC) based DC link voltage regulator is used to estimate the reference current signal and control the operation of the SPV interfaced shunt APF. Maximum Power Point Tracking (MPPT) algorithm is also employed to obtain the optimum maximum power point. The response of the SPV interfaced ZSI-shunt APF for mitigation of current harmonic distortions and reactive power compensation are investigated and compared with SPV interfaced Voltage Source Inverter (VSI) based shunt APF. The proposed SPV interfaced shunt APF employed with the FLC-based instantaneous reactive power theory control algorithm offers long lasting compensation against current-based distortions and reactive power requirements. The performance of the SPV interfaced ZSI based shunt APF has been verified by the simulation and experimental study. These results confirm the practicability of the proposed system in various load conditions with effective harmonic mitigation capability.

This Paper Presents Novel DC-DC Converter Based Closed Loop Control of BLDC Motor for SPV fed Water Pumping System Solar Photovoltaic (SPV) Array fed Water pumping System Utilizing Buck-boost DC-DC Converter in order to extract the maximum available power from Solar system. Solar energy has the greatest availability compared to other energy sources. For such solar PV systems, maximum power point tracking control is preferred for efficient operation. This concept is dealing with INC method which is one of the MPPT methods. This study deals with a buck–boost converter controlled solar photovoltaic (SPV) array fed water pumping in order to achieve the maximum efficiency of an SPV array and the soft starting of a permanent magnet brushless DC (BLDC) motor. The current sensors normally used for speed control of BLDC motor are completely eliminated. The speed of BLDC motor is controlled through the variable DC-link voltage of a voltage-source inverter (VSI). The VSI is operated by fundamental frequency switching, avoiding the losses due to high-frequency switching, in order to enhance the efficiency of the proposed system.

Solar photovoltaic (SPV) system fault diagnostics is vital in advanced supervision because it can alert users to catastrophic failure or greater risks. To provide green and clean energy using solar, it is mandatory to analyse various faults associated with photovoltaic system which can result in energy deficit and system breakdown and may lead to fire hazards which are often difficult to avoid. Hence, as an endeavour to improve the efficiency level, more study beginning with modelling of SPV system with its parameter estimation and types of SPV faults is aimed in this work.

Integration of renewable energy sources to the grid-connected system has influenced scholarly research in recent times to evolve solutions for power electronic conversion. Particularly, solar photovoltaic (SPV), being a resource available throughout the year, demands needful research to meet the demand for industrial applications. To facilitate SPV, multilevel inverters (MLIs) and cascaded H-bridge inverters (CHBIs) are proposed in the literature to meet the power requirement. However, these circuits suffer from efficiency loss, economic aspects of DC sources usage, and switching losses. Hence, in this research, a new power converter topology is projected to improve the overall efficiency of SPV systems. Further, a three-level approach involving (i) SPV Panel-Temperature Reduction (SPV-PTR) Setup, (ii) Boost Multilevel Direct Current Link Converter (BMLDCLC), and (iii) use of effective snubber modules (SM) are effectively handled to promote the industry readiness of the proposed system. From a detailed system investigation, it is seen that the proposed arrangement has minimized the power loss to ensure better quality in output. Furthermore, the software-based results and hardware setup of the planned comprehensive converter have shown promising results in terms of (i) reduced voltage stress, (ii) reduced total harmonic distortion (THD) without filter component, and (iii) reduced power loss. It is observed that the experimental setup has reported a 12.9% of excess heat removal, 5% decrease in harmonics, and 33% switch reduction than the existing MLI schemes. In addition, the proposed setup is suggested to apply for industrial purposes indicate its efficacy to be a solution in real time.

Problematiken för anskaffning av standardsystem inom en verksamhet kan bli omfattande,

särskilt ifall företaget tar förhastade beslut, och därmed blir anskaffningen en belastning

istället för tvärtom. Metodutvecklingen för anskaffningen av standardsystem är ett område

som inte är utforskat i stor utsträckning. Idag finns det en generell metod som används vid

anskaffning av standardsystem. Metoden kallas för SIV-metod (Standardsystem i

verksamheter) och har utvecklats av bl.a. Anders G. Nilsson i samband med ett projekt som

drevs inom institutet V i Stockholm i början av 1990-talet. SIV-metoden har inte utvecklats

färdigt och behöver därför prövas i fler praktiska fall. Syftet med denna uppsats är ta fram

metoden och pröva den i praktiken för att se hur pass användbar den är. Vi har arbetat med

företaget Koneo i Växjö som är ett IT - relaterat företag och har varit i behov av att

anskaffa ett standardsystem som i deras fall handlade om ett kundvårdssystem, CRM

(Customer Relationship Management).

I vår studie har vi tillämpat SIV-metoden för att se hur användbar den är i praktiken. Efter

genomgånget projekt kan vi konstatera att metoden är användbar i den mening att den ger

vägledning och tar vara på de grund delar som ingår i processen vid anskaffning av

standardsystem.

The problems that occur when obtaining or realising Standardsytem within an organisation,

can be exhaustive if the enterprise rushes to a desicion. Furthermore, this practical

application could be a burden instead of an opportunity. The method for obtaining realising

a standardsystem is an area that has not been studied to any greater extents. In the present,

the SIV-method (SIV: Standardsystem in business) is a general method used in the

relization of a standardsystem. The SIV-method has been developed by amongst others,

Anders G. Nilsson, in a project assigned by the V institute in Stockholm, Sweden. The

reason for this thesis is that the SIV-method is not considered complete and therefore we

will attempt to investigate this in a practical case. The purpose of this thesis is to test the

Siv-method in an organisations process for acquiring a standardsystem.

This research is co-operated in with the enterprise of Koneo. That is in need of a

standardsytem that concerns and operates the intergration of a Customer Relation

Managment system, CRM- system. After accomplishing our project we can establish that

SIV-method is useful, by means of that it takes into consideration main parts of the process

when obtaining a standardsystem.

The complexity of System-on-a-Chip (SoC) is continuing to increase due to the shrinking die size, increase in the number of sub-modules, power efficiency, performance, higher functionality and used protocols. This has an impact on the verification process related to the overall design process. For the verification process, there are commercial products that can be applied in order to verify and test certain Intellectual Properties (IP) but also platforms that lack these tools. This thesis focuses on the issue where a system has to be constructed that helps the verification and testing process of a data bus protocol used by the Device Under Testing (DUT). The study of the Serial Peripheral Interface (SPI) gives the examples of some issues that can be faced during applying this data bus protocol to any given system. Different kinds of testing and verifying methods are addressed in order to show what the tools can be when applying new DUT to a system or examining the data bus protocol it uses. The flow of a design process is studied by showing the iterations of a particular system that was to be created to meet the need that were introduced while examining the issues relating this subject. This flow can be said to start from ground level and end to the final iteration where the system could be created from. The functionality and structure of a Multipurpose Verification System that was created during this thesis are explained. The proofing process of this system is showed by examining the simulation and synthesis reports. The outcomes and future development ideas are discussed as well. This thesis showed that the study in hand has benefits to Nokia as the applying company and the system could be added to the company tool library after modifying it to be used as a stand-alone IP
Järjestelmäpiirien (SOC) kompleksisuus on jatkuvassa kasvussa johtuen johdinpiirien pienenemisestä, alijärjestelmien määrän kasvusta, vaatimuksista tehonkulutuksessa, suorituskyvyn kasvusta, toiminnallisuuden kasvusta ja käytettävistä protokollista. Näillä attribuuteilla on vaikutusta kokonaissuunnitteluprosessin verifiointiprosessiin. Verifiointiprosessiin on tällä hetkellä saatavilla kaupallisia sovelluksia, joita voidaan hyödyntää kolmannen osapuolen suunnitteleman systeemin testaukseen ja verifioitiin. Samalla on myös olemassa testausalustoja, joista nämä sovellukset puuttuvat. Tämä diplomityö keskittyy tilanteeseen, jossa täytyy rakentaa systeemi joka helpottaa testattavassa laitteessa (DUT) käytettävän tietoväyläprotokollan verifiointi- ja testausprosessia. Serial Peripheral Interface (SPI)-väyläprotokollan tutkimus tuo esiin esimerkkejä, joihin voidaan törmätä, kun kyseistä väyläprotokollaa käytetään missä tahansa sitä hyödyntävässä systeemissä. Diplomityössä tutkitaan erilaisia testaus- ja verifiointimetodeja, jotta voidaan osoittaa mitä erilaisia työkaluja voidaan hyödyntää, kun uusi testattava laite lisätään olemassa olevaan systeemiin tai tutkitaan tämän käyttämää väyläprotokollaa. Kokonaissuunnitteluprosessia on tutkittu esittelemällä tietyn järjestelmän iteraatiovaiheita, joka kehitettiin ratkaisemaan aiemmin tarkasteltuja, tähän aiheeseen liittyviä ongelmia. Suunnitteluprosessin voidaan katsoa alkaneen tilanteesta, jossa mitään konkreettista ei ollut vielä valmiina ja päättyvän tilanteeseen jossa järjestelmän viimeinen iteraatio voitiin alkaa konkretisoimaan. Monikäyttöisen syntetisoituvan verifiointijärjestelmän funktionaalisuus ja rakenne esitellään. Tutkimalla simulointi- ja synteesiraportteja näytetään tämän järjestelmän varmennusprosessi. Diplomityön toteutumista ja tulevaisuuden jatkokehitysideoista keskustellaan. Tämä diplomityö osoittaa, että Nokia soveltajayrityksenä pystyy hyödyntämään tämän tutkielman lopputulemia. Lisäksi työn tulokset voidaan lisätä, modifioinnin jälkeen, yrityksen komponenttikirjastoon toimimaan itsenäisenä instanssina

De flesta metoder, verktyg och arbetssätt som används vid traditionell projektledning har använts under en lång tid trots att de yttre förutsätt-ningarna har förändrats. Systemutvecklingsbranschen upplevde de traditionella metoderna att driva projekt som oerhört statiska och tröga, därför utvecklades mer lättrörliga metoder som kom att kallas agila systemutvecklingsmetoder. Fram till år 2007 fanns inte en strukturerad process för hur valet och implementeringen av en agil systemutveckl-ingsmetod bör gå till. Det finns idag några ramverk som beskriver hur val och implementering av en agil metod kan bedrivas. Inget av dessa ramverk tar dock i beaktande eller utgår ifrån en organisations strategi eller vikten av strategisk passform. Syftet med denna rapport har varit att undersöka hur en agil systemutvecklingsmetod kan väljas utifrån strategisk passform. Undersökningen har även syftat till att studerade förändringar som kan krävas i en organisations projektstyrningsmodell för att införa en agil systemutvecklingsmetod. För att besvara syftet har en fallstudie utförts på Statens tjänstepensionsverk. På SPV har en ut-värdering med TS-metoden genomförts för att bedöma olika agila systemutvecklingsmetoders strategiska passform. Med hjälp av TS-metoden har agila systemutvecklingsmetoder bedömts mot en organi-sations strategiska mål. Resultatet från utvärderingen var att de agila systemutvecklingsmetoderna DSDM och Scrum ansågs ha den bästa strategiska passformen. Då DSDM till stor del är ett ramverk är en kom-bination av dessa båda systemutvecklingsmetoder möjlig. TS-metoden har resulterat i en relativ bedömning mellan de agila systemutveckl-ingsmetoderna. Utifrån denna bedömning har de agila systemutveckl-ingsmetoderna kunnat rangordnas utifrån ett strategiskt perspektiv. Införandet av en kombination av metoderna har inneburit att arbetet kommer att utföras iterativt istället för sekventiellt och detta har inneburit att beslutspunkterna i projektstyrningsmodellen har förändrats. Även styrning efter TKQ har försvunnit.
Most of the methods, tools and approaches used in traditional project management come from the Cold War days. System development sector experienced the traditional methods of managing projects as extremely static and slow and therefore developed more agile methods, agile sys-tem development methods. By the year 2007 there was not a structured process for the selection and implementation of an agile method. There is currently some framework that describes how the selection and im-plementation of an agile method can be conducted. None of these frameworks will be considered or assume an organization strategy and the importance of strategic fit. The purpose of this report was to investi-gate how an agile software development method can be chosen based on strategic fit. The survey also aimed to study the changes that would be required in an organization's project management model in order to introduce an agile system development methodology. To answer the question, an evaluation with TS-method was performed. In the TS-method has agile software development methodologies assessed against an organization's strategic goals. The result from the evaluation was that the agile software development methods DSDM and Scrum were con-sidered to have the best strategic fit. When the DSDM largely is a framework a combination of the two agile software methods is possible. TS-method gave a relative assessment between the agile software devel-opment methods. Based on this assessment, the agile software devel-opment methods could be ranked from a strategic perspective. The in-troduction of a combination of methods has meant that the work will be performed iteratively rather than sequentially, and this has meant that the decision points in the project management model have changed. Although control with TKQ has disappeared.

This diploma thesis addresses the problem of liquid and gas simulation, it particularly deals with computer simulation of flow of viscous newtonian liquids with a free surface. A main goal of this work is to create an efficient simulation model, utilizing the benefits of current GPU parallel architecture for general-purpose computing. I chose to implement Smoothed Particle Hydrodynamics, a lagrangian particle-based method. A significant portion of this thesis consists of speed analysis of the implemented algorithm, comparison with other authors' achievements in the field and a demonstration of benefits brought by GPU involvement in the computation. As an output of the thesis I present an interactive computer program that allows for real-time simulation (and visualization) of water-like fluids.

Abstract The automotive industry has for some years considered hydraulic regeneration systems for use in hybrid vehicles; combining the concurrent use of an internal combustion engine and a hydraulic system to reduce fuel consumption and increase performance. This study describes the development of a hydraulic hybrid system using a small passenger vehicle (SPV) model and a hydraulic hybrid pump/motor (P/M) model. A model of an SPV vehicle was developed and validated using MATLAB Simulink. Simulations were performed to analyse and test the performance of the hybrid system. This study addresses the gap related to the prediction of the performance of the hydraulic hybrid system for use on an SPV. A novel control system was developed to simulate the drive cycle and predict the fuel-saving of the hydraulic hybrid system. Variables included accumulator size, hydraulic P/M displacement and accumulator pre-charge, which were adjusted to optimise the hydraulic hybrid system. The Fuel consumption of the model before the implementation of the hybrid system was calibrated with the recorded fuel consumption of the test vehicle. The hydraulic hybrid system was then developed and implemented to the SPV model along with a revised control system. The fuel-saving of a novel hydraulic hybrid control was estimated using MATLAB Simulink. A controller was developed to manage the distribution of energy between the hydraulic system and the diesel engine. The effects of the hybrid system on the brakes and the engine demand were analyzed. The results indicated a 45% reduction in diesel engine demand and a 65% decrease in brake usage throughout the drive cycle. The model of the hydraulic hybrid passenger vehicle predicted a fuel saving of approximately 17%. This study shows that the hydraulic hybrid system can potentially improve fuel consumption and optimize engine performance in passenger vehicles.
