A coupled nuclear reactor thermal energy storage system for enhanced load following operation

Nuclear power plants operate most economically at a constant power level, providing baseload electric power. In an energy grid containing a high fraction of renewable power sources, nuclear reactors may be subject to significantly variable power demands. These variable power demands can negatively impact the effective capacity factor of the reactor and result in severe economic penalties. Coupling a nuclear reactor to a large thermal energy storage block will allow the reactor to better respond to variable power demands. In the system described in this paper, a Prismatic–core Advanced High Temperature Reactor supplies constant power to a lithium chloride molten salt thermal energy storage block that provides thermal power as needed to a closed brayton cycle energy conversion system. During normal operation, the thermal energy storage block stores thermal energy during the night for use in the times of peak demand during the day. In this case, the nuclear reactor stays at a constant thermal power level. After a loss of forced circulation, the reactor reaches a shut down state in less than half an hour and the average fuel, graphite and coolant temperatures remain well within the design limits over the duration of the transient, demonstrating the inherent safety of the coupled system.
Tune-all wideband planar filters for KAT-7

A new type of wideband lters, with tunability in both the centre frequency and bandwidth, is presented in this thesis. These lters are based on perturbed ring-resonators in cascade, while varactor diodes are used for electronic tuning. The Karoo Array Telescope (KAT-7) requires a front-end lter that has the ability for ne-tuning the response after fabrication, in order to obtain the designed ltering response. Not only are tune-all characteristics required, but also wide bandwidth, at passband, high selectivity and implementation in microstrip technology. In this thesis an extensive investigation of both tunable and wideband lters is done, in order to nd a possible solution for the KAT-7 speci cations. Following this investigation, it is concluded that no suitable design approach for tune-all wideband lters, implemented in microstrip, exists in current literature. Therefore, this thesis proposes a new type of lter along with the development of a complete design procedure. Two lters are designed with this procedure to achieve the required passband from 1.2 to 1.95 GHz (i.e. a fractional bandwidth of 49%). In the rst lter design, with a network consisting of 4 cascaded ltering-sections, the centre frequency is 5% tunable and the bandwidth 17.5%. With the second lter consisting of 6 cascaded ltering-sections, higher selectivity is achieved but with lower return loss. Here the centre frequency is 8.5% tunable and the bandwidth 18.8%. The theoretical results are validated with the fabrication of both lters. This design is very unique in that it achieves wide bandwidth, is realisable in microstrip and most importantly is tunable in both the centre frequency and bandwidth. An advantage of this design procedure is that full wave simulations are minimal, due to the complete circuit models used for optimisation. ii Stellenbosch University http://scholar.sun.ac.za
Noncontact Extraction of Human Arterial Pulse with a Commercial Digital Color Video Camera

Noncontact Extraction Of Human Arterial Pulse With A Commercial Digital Color Video Camera Maria I. Davila, Ph.D. Department of Bioengineering University of Illinois at Chicago Chicago, Illinois (2012) Dissertation Chairperson: Dr. Stephen W. Porges The current study introduces and evaluates digital color video as a noncontact technology that can be applied to accurately extract human arterial pulse, respiration rate, and arterial pulse amplitude, during a variety of challenges. The first objective was to understand the physiological significance of the features of the pulse signal extracted from digital color video technology by researching the interaction of the key components in the system (subject physiology, camera, and incident light). Once the dynamic relationship among the components was understood, the second objective was to validate the derived measures against criterion signals. The third objective was to develop a reliable system capable of delivering physiologically validated signals via digital color video technology for offline and online analysis. The system was evaluated on 20 subjects during a variety of challenges under offline and online conditions. Measures of arterial pulse were derived from the novel signal with sufficient precision to quantify instantaneous heart rate (IHR), two components of heart rate variability (i.e., low frequency (LF) and respiratory sinus arrhythmia), breathing rates, and instantaneous pulse amplitude. The new noncontact measures were compared with criterion contact measures. The results show that the system is reliable to measure arterial pulse, respiration rate and pulse amplitude. A real time system capable of accurately extracting the new noncontact measures that will monitor heart rate, heart rate variability, and respiration was developed. Understanding the information obtained by the digital video camera and its relationship to physiological parameters may open research opportunities to explore applications of this new methodology in psychophysiology, medicine, and applied areas including human factors research.
Podcasting in distance learning: true pedagogical innovation or just more of the same?

This chapter explores how podcasting can be used to support and enhance the student experience, with a focus on tertiary-level distance education contexts. It begins with a review of the rationale behind the use of podcasting and digital audio for distance teaching and learning, including a consideration of the unique features and attributes of podcasting that differentiate it from older or pre-existing educational technologies. The authors then showcase a number of examples involving the use of podcasting in distance e-learning and blended learning, drawn from the exemplary practices of educators across the globe. Discussion of these exemplars centers around four major themes: increasing learner motivation and engagement; facilitating and enhancing learning outcomes; impacting on mobility and lifestyle learning; and fostering a sense of community, with the aim of contributing to the establishment of an evidence-based case about the benefits of podcasting in relation to addressing the needs of distance education students, as well as illuminating some of the problems and barriers that exist. The chapter concludes with a number of recommendations for distance educators.

Subcontracting versus health and safety: An inverse relationship

The construction industry has an unenviable reputation of being one of the worst industries in the UK in respect of health and safety (H&S) performance. Among other factors, research points to subcontracting as one of the factors influencing safety performance on construction sites. With about 80% of construction works in the UK being subcontracted, clearly it has become imperative to investigate this inverse subcontracting-H&S relationship. This situation is exacerbated by the increasing complexity of construction technologies which inevitably implies growth in specialisation, hence an increase in subcontracting. A critique of literature on H&S and subcontracting shows that this phenomenon is attributable inter alia to the lack of resources by small subcontractors to enable them invest in H&S, ambiguities about H&S responsibilities arising from complex subcontracting relationships, and the fierce level of competition for contracts among subcontractors resulting in economic survival being prioritised over H&S. Putting these factors in context, the main arguments giving justification for the need for further research into this phenomenon are indicated. The critical research questions, research aim and objectives are also highlighted, thus setting the premise for research work to expound on these factors and offer suggestions for mitigating this inverse relationship.

Different Modalities of Analgesia in Open Heart Surgeries in Mansoura University

--- Background: Opioid usage in cardiac surgery is considered to be the corner stone in management. Inadequate pain control after cardiac surgery complicates patient recovery and increases the load on healthcare services. Multimodal analgesia can be used to achieve better analgesic effect and improves patient outcome. Material and methods: A total of 90 patients undergoing cardiac surgery with median sternotomy were randomly allocated equally into three groups intraoperatively where first group received continuous infusion of high dose opioids, second group received boluses of low dose opioids and third group received multimodal non opioid analgesics including dexmedetomidine, ketamine and magnesium sulphate. All patients received the same post-operative analgesic regimen consists of morphine patient controlled analgesia (PCA). Results: Patients in multimodal non opioid group had more stable hemodynamics intra and postoperatively. Also, patients in multimodal group had lower pain scores extubation, earlier extubation, shorter ICU stay, earlier mobilization and earlier return of bowel movements compared to patients of both groups received intraoperative higher opioid doses. Conclusion: Combination of Dexmedetomidine, ketamine and magnesium for intraoperative analgesia offered an effective analgesic profile, more stable hemodynamics, faster extubation time, shorter ICU stay, earlier mobilization and earlier return of bowel movements with more sedated patients in the immediate postoperative period in patients undergoing open heart surgery. shortening (FS), artery pressure and
Energetic Consequences of Series and Parallel Springs in Lower-Extremity Powered Prostheses

We present electric energetic consequences for mechanical design trade-offs in lower-extremity powered prostheses. There are four main hardware components commonly implemented in these devices that can be tuned to achieve desired performance: motor, reduction ratio N, series spring stiffness Ks, and parallel spring stiffness Kp. The allowed joint range of motion is a fifth parameter that can also drastically change energy consumption. We apply a kinematically clamped analysis to the system equations to map the electric cost of transport (COT) for knee and ankle level-ground walking, in addition to ankle stair ascent and descent. We also utilize an optimization procedure to identify minimum energy hardware configurations. The energy map provides insight into consequences of variance from optimal parameters. Our results support the contribution of the series elastic element for improved power output. Parallel stiffness can provide up to 8% improvements in walking with minimal negative effect with varied terrain, and a varying ankle transmission ratio can similarly improve COT by 8% from level-ground to stair ascent. Limited dorsiflexion can further improve COT by 30%. These observations can provide the designer clarity to how design decisions modulate hardware performance.
Effect of structural water on the elasticity of orthopyroxene

Abstract As a major nominally anhydrous mineral (NAM) in the Earth’s upper mantle, orthopyroxene could host up to several hundred parts per million H2O in its crystal structure and transport the H2O to the deep Earth. To study the effect of structural H2O on the elasticity of orthopyroxene, we have measured the single-crystal elasticity of Mg1.991Al0. 065Si1.951O6 with 842–900 ppm H2O and 1.64 ± 0.20 wt% Al2O3 at ambient conditions using Brillouin spectroscopy. The best-fit single-crystal elastic moduli (Cijs), bulk (KS0), and shear (G0) modulus of the hydrous Al-bearing orthopyroxene were determined as: C11 = 235(2) GPa, C22 = 173(2) GPa, C33 = 222(2) GPa, C44 = 86(1) GPa, C55 = 82(1) GPa, C66 = 82(1) GPa, C12 = 75(3) GPa, C13 = 67(2) GPa, and C23 = 49(2) GPa, KS0 = 111(2) GPa, and G0 = 78(1) GPa. Systematic analysis based on the results presented in this and previous studies suggests that the incorporation of 842–900 ppm H2O would increase C13 by 12.0(7)% and decrease C23 by 8.6(8)%. The effects on C11, C22, C33, C44, C66, KS0, and VP are subtle if not negligible when considering the uncertainties. The C55, C12, G0, and VS are not affected by the presence of structural H2O. Although laboratory experiments show that Fe,Al-bearing orthopyroxenes can host up to 0.8 wt% H2O in its structure, future high-pressure-temperature elasticity measurements on orthopyroxene with higher H2O content are needed to help better quantify this effect.

Building new Knowledge Networks: A Europe–China Perspective on RaD Offshoring

This paper explores how offshoring of R&D affects innovation performance based on three recent cases of R&D transfer from Scandinavia to China. One globally leading packaging company moved R&D to China and immediately arranged innovation competitions between three selected universities in order to improve their innovation performance within distribution equipment. Two other Scandinavia originated companies - now global leaders within robotics and diabetes treatment - did on the other hand not cooperate as closely with local universities when it transferred R&D to China - and captured less innovation performance. By combining theories on ambidexterity, knowledge transfer and networking, a theoretical framework is developed to analyze the different strategies for local knowledge network interaction that are deployed by the case companies. The analysis suggests that close interaction and cross-fertilization with local knowledge networks are of eminent importance if newly established R&D offsprings are to improve overall innovation performance.

Iron-binary phase diagrams

At the official dinner of a. meeting in May 1939, I was seated next to Max Hansen. When I congratulated him on the well deserved success of his "Aufbau der Zweistoff-Legierungen," he smiled: "yes, it was a struggle with the hydra, and so it has taken me seven years," meaning that whenever he had thought to have finished the phase diagram of a particular system, new evidence would turn up like the new heads of the Greek monster. There is no need to point out the importance of assessed phase diagrams to metallurgists or even anyone concerned with the technology and applica tion of metals and alloys. The information contained therein is fundamental to considerations concerning the chemical, physical and mechanical properties of alloys. Hansen's German monograph was followed by a revised English edition in 1958 with K. Anderko and the supplements by R.P. Elliott (1965) and F.A. Shunk (1969). All those who have made use of these volumes will admit that much diligent labour has gone into this work, necessary to cope with the ever increasing number of publications and the consequent improvements.

Improving Japanese Developers Practice in Analyzing Software Features by Using Kano model and Quality Function Deployment of RAB Software Developmen

As the emerging global market is triggering and escalating great business in software market, Japanese developers are driven to seek and grow the opportunities to be the leader in the world. As the second strongest player, Japan is far behind U.S as the first player. One of the main reasons of this is coming from the slow development practice performed by Japanese developers compared to the U.S. which is more innovative and has faster time to market. The Japanese has been putting too much emphasize on quality which lies on customer requirements management of System Development Life Cycle (SDLC) that results in inefficient design which leads to inefficient time, and cost. Currently, as one of Japanese developers, PT. XYZ plans to develop RAB-software who’s the research is done in PU – NTB. Hence, customer requirements are captured and identified by using Kano Model to classify and justify the priority of requirements in accordance to the level of satisfaction. They are then translated into House of Quality of Quality Function Deployment in order to design priority-based requirements in achieving time efficiency, cost reduction, and design optimization towards SDLC process. In the end, 48% of design to be developed is able to be reduced through this research.

From motion perception to Bob Dylan.

Directionals like from New York, through the tunnel, into the dark represent a major class of spatial expressions, typically associated with locomotion (verbs). Semantically, many of their aspects are notoriously difficult to characterize, among them their characteristics (classification, typology), their relation to locatives (e. g. in New York, in the tunnel, in the dark), and their composition with verbs (especially in non-locomotion contexts). Cognitively, there is a big theoretical gap to fill between aspects of low-level motion perception and the conception of static situations in terms of non-actual (loco)motion. This paper first critically discusses Zwarts’ explicit formal account of directionals, then introduces a Cognitivist attentional semantics and finally applies the Cognitivist approach to directionals. It will be shown that attention-based conceptual representations are necessary components in directional semantics and explanatory for the mentioned aspects.
Contract session: Application of genetic technologies to the New Zealand sheep industry

Introduction The contract session, “Sheep Improvement Limited (SIL) the first 10 years”, was presented at the 2009 NZSAP conference (Newman 2009). This described the establishment and subsequent development of Sheep Improvement Ltd (SIL), and documented the range of traits recorded and the genetic improvement achieved since SIL began in 2000. Six years later, SIL continues to be the main delivery mechanism for genetic improvement in the New Zealand Sheep industry, with an expanded range of traits recorded and with many breeding values informed by results from genomic tests. These genomic tests have been developed from significant investment over several decades and are beginning to deliver on the promise they hold for genetic improvement. The International Sheep Genomics Consortium (ISCG), of which Ovita was a member, developed single-nucleotide polymorphism (SNP) genomic panels needed for the estimation of molecular breeding values (mBVs). This research has enabled Ovita, the Pastoral Greenhouse Gas Research Consortium (PGgRc) and the FarmIQ Primary Growth Partnership to develop and deliver genomic breeding values through SIL to the New Zealand sheep industry. mBVs have been ‘blended’ with the quantitative estimated breeding values (eBVs) already available through SIL, and appropriate economic models, to provide the sheep industry with the greatest suite of tools it has ever had to achieve genetic improvement. This contract documents the developments made to achieve this.
Highly Doped Nd:YAG Laser in Bounce Geometry Under Quasi-Continuous Diode Pumping

Nanosecond and picosecond laser pulses play increasing role in a variety of applications, such as microsurgery, micromachining, ranging, optical parametric amplifiers pumping, remote sensing, nonlinear optics, etc. Efficient diode pumped solid state lasers represent widely used sources of such pulses. For applications such as laser ranging and some nonlinear optical effects investigation, the extremely short pulses are not needed and pulses in the range from tens of picoseconds to units of nanoseconds at repetition rates below 1 kHz are optimal. Research and development of such laser systems is the subject of this chapter.
