AMOC and water-mass transformation in high- and low-resolution models: Climatology and variability

Water-mass transformation in the North Atlantic plays an important role in the Atlantic Meridional Overturning Circulation (AMOC) and its variability. Here we analyze subpolar North Atlantic water-mass transformation in highand low-resolution versions of the Community Earth System Model (CESM1) and investigate whether differences in resolution and climatological water-mass transformation impact low-frequency AMOC variability. We find that high-resolution simulations reproduce the water-mass transformation found in a reanalysis-forced high-resolution ocean simulation more accurately than low-resolution simulations. We also find that the low-resolution CESM1 simulations, including one forced with the same atmospheric reanalysis data, have larger biases in surface heat fluxes, sea-surface temperatures and salinities compared to the high-resolution simulations. Despite these major climatological differences, the mechanisms of low-frequency AMOC variability are similar in the highand low-resolution versions of CESM1. The Labrador Sea WMT plays a major role in driving AMOC variability, and a similar NAO-like sea-level pressure pattern leads AMOC changes. However, the high-resolution simulation shows a more pronounced atmospheric response to the AMOC variability. The consistent role of Labrador Sea WMT in low-frequency AMOC variability across highand low-resolution coupled simulations, including a simulation which accurately reproduces the WMT found in an atmospheric reanalysis-forced high-resolution ocean simulation, suggests that the mechanisms are similar in the real world.
Care-work policies: conceptualising leave within a broader framework1

The central argument of this chapter is that statutory Parental Leave policy must be conceptualised within a broader framework of care-work policies and cultural ideas over care tasks. We propose a model based on structural and cultural dimensions. The former includes leaves (Maternity, Paternity, Parental), ECEC services, the relationship or gap between leave and ECEC entitlements, occupational welfare, and family structures (e.g. proportion of children living with two parents); the latter include levels of gender inequality and intergenerational solidarity orientation. Considering these six dimensions we focus on four countries, namely Germany, Italy, Sweden and the UK, representing well-established welfare regime models. Our analysis highlights how Germany and Sweden seem more similar than might be expected in light of established welfare regime models, while Italy and the UK are in contrast somewhat similar in terms of their Parental Leave models, whilst showing many differences in relation to other social actors involved in providing welfare goods.
To Resolve The Voltage Unbalance Of The Dc Links In Different H-Bridges Based Solid State Transformer (Sst)

As the expansion of the dc distribution system and the augment of the penetration of distributed generations an intelligent transformer with the capability to actively supervise the power and allowing for the easy connection of the distribution resources is becoming essential. The solid state transformer (SST) has the features of immediate voltage regulation, voltage sag compensation, fault isolation, power factor correction, harmonic isolation and dc output. Acting very much like an energy router, each SST has bidirectional energy flow control potential allowing it to control active and reactive power flow and to handle the fault currents on both low- and high-voltage sides. Its large control bandwidth offers the plug-and-play feature for distributed resources to speedily recognize and respond to changes in the system. This paper proposes a 20-kVA cascaded H-Bridge multilevel converter-based SST to directly interface with 7.2-kV single-phase distribution voltage level. The SST consists of a cascaded multilevel ac/dc rectifier, dual active bridge (DAB) converters with high-frequency transformers. The DAB converter regulates the 400-V-low-voltage dc bus and added dc/ac inverters can be added to present a 60 Hz 120/240-V ac residential voltage
Design of the half-bridge, series resonant converter for induction cooking

The forced commutated, half-bridge, series resonant power converter is well suited for induction cooking. A detailed analysis is made of the operation of this power converter to obtain the information needed for a complete design procedure. The values of the reactive components and the voltage and current requirements for all the power components can be calculated with this procedure for a given cooking vessel (experimental measurement of parameters needed), grid voltage and maximum output power. Experimental results are presented. <<ETX>>

Understanding the Determinants of Problem-Solving Behavior in a Complex Environment

It is often argued that problem-solving behavior in a complex environment is determined as much by the features of the environment as by the goals of the problem solver. This article explores a technique to determine the extent to which measured features of a complex environment influence problem-solving behavior observed within that environment. In this study, the technique is used to determine how a complex flight deck and air traffic control environment influences the strategies used by airline pilots when controlling the flight path of a modern jetliner. Data collected aboard 16 commercial flights are used to measure selected features of the task environment. A record of pilots' problem-solving behavior is analyzed to determine to what extent behavior is adapted to the environmental features that were measured. The results suggest that the measured features of the environment account for as much as half of the variability in pilots' problemsolving behavior and provide estimates on the probable effects of each environmental feature.
Dynamic Stability of Maglev Systems

Because dynamic instability is not acceptable for any commercial maglev systems, it is important to consider this phenomenon in the development of all maglev systems. This study considers the stability of maglev systems based on experimental data, scoping calculations, and simple mathematical models. Divergence and flutter are obtained for coupled vibration of a three-degree-of-freedom maglev vehicle on a guideway consisting of double L-shaped aluminum segments attached to a rotating wheel. The theory and analysis developed in this study identifies basic stability characteristics and future research needs of maglev systems.
Benign and Malignant Breast Cancer Features Based on Region Characteristics

Breast cancer is one of the most common malignant diseases among women. Mammography is at present one of the available method for early detection of abnormalities, which is related to breast cancer; there are different lesions that are breast cancer characteristic such as masses, which can be detected through this technique. In this work, we explore the application of density slicing and region growing techniques to the problem of finding the boundary of different breast tissue regions in mammograms and extracting these regions. The goal of the segmentation algorithm is to see if density slices images and region growing algorithm could separate different densities for the different breast patterns and calculating there features. Segmentation of the mammogram into different mammographic densities is useful for risk assessment and quantitative evaluation of density changes and for extracting the cancer regions. Our proposed methodology for the segmentation of mammograms has been tested on Mini-MIAS database images. The final result is the segmentation of Region of I interest (ROI) with edge map and different features extraction for analysis where the extracted regions are saved as images and the texture features were calculated using Gray Level Co-Occurrence Matrix (GLCM) along 0^°such as contrast, correlation, homogeneity, sum variance, entropy, energy, mean values and others to differentiate between the Benign and Malignant images. It was found that the features such as contrast, correlation, smoothness, and difference variance are the optimal features to differentiate between benign and malignant regions where the other features are approximately the same. Also region growing method is very fast for extracting cancer regions. Our results are important to design artificial intelligence system to diagnostic breast cancer into benign and malignant cancer

USO DEL PROTOCOLO OVSYNCH EN VAQUILLONAS LECHERAS CON O SIN CUERPO LÚTEO FUNCIONAL AL INICIO DEL TRATAMIENTO

With the objective of compare ovarian response and pregnancy rates in dairy heifers that received two presynchronisation treatments with prostaglandines to induce presence (CLF+) or absence (CLF-) of a functional corpus luteum at the initiation of the Ovsynch protocol, 22 Holando Argentino heifers were assigned randomly to receive two injection of 750 ug of tiaprost, at days -22 and -11 (CLF+ group, n=11) or at days -14 and -3 (CLF- group, n=11). Presence or absence of a functional corpus luteum was confirmed by ultrasonography and measurement of plasma progesterone concentrations, therefore two CLF+ and one CLF-heifers were dropped from the experiment. At day 0 both groups received 8 mg of buserelin; at day 7, 750 mg of tiaprost and at day 9,8 mg of buserelin. Heifers were bred by fixed-time artificial insemination 15 hours after treatment. Percentage of animals with a ≥8 mm follicle at day 0 and its diameter were similar between gropus (P>0.05). Following first buserelin injection ovulation occurred in 94.1% and luteinization in 5.9% of these follicles (P>0.05). Percentages of animals with a functional corpus luteum at day 7 were similar between groups (100% and 90%, for CLF+ and CLF-, respectively; P>0.05) while its progesterone concentrations were greater in CLF+ (3.5 +-0.7 vs 2.2 +- 1.2 ng/ml; P 0.05). Dominant follicle diameter was greater in CLF- so much at day 7 (P=0.05) as at day 9 (P 0.05). Pregnancy rates were similar between groups (66.7% and 70%; P>0.05). In conclusion, used of two presynchronisation treatments with prostaglandines to induce presence (11 days post-second PGF2a) or absence (3 days post-second PGF2a) of a functional corpus luteum at the initiation of the Ovsynch protocol produces similar ovarian response (ovulation, luteal phase synchronisation and luteolysis), what would explain similarity between pregnancy rates obtained in both groups.
Development of a bicycle anti-lock braking system prototype / Bisikletlerde Kaymayı Önleyici Fren Sistemi Prototipi Geliştirilmesi

In order to satisfy the increasing need for security and comfort the active safety systems of the smaller vehicles like the motorbikes, scooters, e-bikes and bicycles have an intensively studied research topic over the last decade. This paper describes the development of a hydraulic type anti-lock braking system (ABS) prototype for bicycle applications. Based on vehicle dynamics of bicycles, a mechanical model has been built and a novel ABS control algorithm has been designed. This algorithm is based on a newly developed reference speed calculation method which uses the angular acceleration values of the wheels. The proper operation of the algorithm has been proved through simulations and based on the results a prototype has been built. In the prototype system the algorithm has been implemented on an external controller module which involves a Continental-developed motorbike hydraulic electronic control unit. The functionality of the prototype system has been verified on a test track in several real road surface conditions such as dry and wet asphalt, grassy ground and dirt road.

Design and fabrication of AlGaN/GaN HEMTs with high breakdown voltages

Gallium nitride based transistors will make up a large portion of the power electronics and the microwave electronics sectors in the very near future, replacing traditional materials such as silicon (Si) and gallium arsenide (GaAs). The work in this thesis focuses on AlGaN/GaN high electron mobility transistors (HEMTs) in particular, with the aim of gaining the maximum potential out of them with regards to breakdown voltage. GaN based devices are able to breakdown at higher voltages compared to Si or GaAs due to its wider band gap (3.4 eV compared to 1.1 eV and 1.4 eV respectively) and although a lot of work has been invested into these devices over the last two decades or so, their full potential has yet to be realised and new solutions are still sought to provide a complete engineering solution which will make them competitive and commercially viable. One of the main obstacles is the high electric fields generated at the drain side of the gate which have prevented these devices from reaching their theoretical breakdown fileld of around 300 V/um. In an attempt to overcome this, several approaches have been investigated in this thesis including metal insulator semiconductor HEMTs (MIS-HEMTs), `gate overlapping' HEMTs, where the gate partially overlaps the source and drain contacts and finally a device employing a Schottky source and a Schottky drain contact. The results given show that a MIS-HEMT can have a substantially larger breakdown voltage compared to a Schottky gate HEMT which is clarified through qualitative simulated electric field work and experimental work. Further, the MIS-HEMT shows a high breakdown field of about 87 V/um when a Schottky drain contact is incorporated. The gate overlapping HEMTs attempts to mitigate completely the large electric field found at the drain edge of the gate. Simulated and experimental results are given for this device concept and reveal that the large electric field peak is indeed removed, however, low breakdown voltages are still incurred due to the closeness of the gate edge to the drain contact. Finally, results are given for a device employing Schottky source and Schottky drain contacts and reveals that present theory may not completely describe the operation of this device.
Keeping older workers committed and employed through formal and informal HRD initiatives

Human resources development (HRD) initiatives are often targeted towards increasing employee organisational commitment. This specifically holds for more informal practices of learning and development, although most learning situations encompass both formal and informal elements. In this chapter a negative relationship is hypothesised between the formality level of HRD initiatives and employee commitment meaning that a higher level of formality is expected to lead to a lower level of organisational commitment. It is also hypothesised that this relationship is stronger for older workers. Although the findings do not support both hypotheses, the results are interesting. For instance, older workers having learned more formally through a new task, job or project, show significantly more continuous organisational commitment. This finding offers the opportunity to arrange new learning and development initiatives to improve older workers’ organisational commitment and prevent them from exiting the labour market early to retire. It also adds new insights to the public debate in which older workers’ knowledge development has often been narrowed to formal training.
Proposal of an open-electric-energy-network (OEEN) to realize cooperative operations of IOU and IPP

After deregulation, there are many entities, such as IOUs (investor owned utilities) IPPs, marketers, aggregators, ISO and security coordinator in power industries. This paper discusses two topics of cooperative operations among IOUs and IPPs. One is an ecological model to simulate the market power of IOU and IPP based on Lotka-Volterra competition model. We can demonstrate the share competition of IOU and LPP by using this model. The co-evolution model of electricity price among IOU and IPP is also introduced. Another is a supplementary power network which makes it possible for many types of dispersed generation plants to generate effectively and to participate in a market circumstance without disadvantages of existing power utilities. This power network is called OEEN (open electric energy network) because the network is open to the many entities with respect to the small scale transactions. Elements of OEEN system are dispersed energy storage devices, load controllers and a data communication link. In OEEN system, a transaction power is treated as an energy package wrapped with an information tag. We call this concept as an electricity-power-packet (EPP). These concepts are discussed in the paper.
Economic analysis of subsurface drip irrigation lateral spacing and installation depth for cotton

Cotton lint yield, seed mass, fiber quality parameters, gross return, and net return were compared for subsurface drip irrigation (SDI) lateral spacing and installation depth in a clay loam soil in western Texas for three seasons. Drip laterals were spaced either in alternate furrows (2 m) or beneath every planted bed (1 m), and installation depths were either 0.2 or 0.3 m beneath the soil surface. Net return was gross return minus fixed and variable costs. Fixed costs included the annual payment for financing the initial investment of SDI materials and installation (5.00% interest over 10 years), the annual land lease, and the annual depreciation of the SDI system. Variable costs were those associated with cotton production and were similar for the two drip lateral spacings. Lint yield, seed mass, and gross and net returns were significantly greater for the 1 m lateral spacing in the first two seasons, but these parameters were significantly greater for the 2 m lateral spacing in the third season. These parameters were consistently greater (either numerically or significantly) for the 0.3 m lateral depth in all seasons. Most fiber quality parameters were not significantly different, and no consistent trends were observed. Lint yields ranged from 640 to 1,635 kg ha-1, and net returns ranged from -$395 to $1,005 ha-1. The low lint yield and resulting net loss were due to a germination failure in the second season for the alternate furrow spaced laterals. Additional seasons of study are required before conclusions might be drawn concerning the most economic lateral spacing for cotton production in the Trans-Pecos region of Texas, but the 0.3 m lateral depth resulted in greater net returns than the 0.2 m lateral depth.
