Data Center Server Virtualization Solution Using Microsoft Hyper-V

Cloud Computing has helped businesses scale within minutes and take their services to their customers much faster. Virtualization is considered the core-computing layer of a cloud setup. All the problems a traditional data center environment like space, power, resilience, centralized data management, and rapid deployment of servers as per business need have been solved with the introduction of Hyper-V (a server virtualization solution from Microsoft). Now companies can deploy multiple servers and applications with just a click and they can also centrally manage the data storage. This paper focuses on the difference between VMware and Hyper virtualization platforms and building a virtualized infrastructure solution using Hyper

Reproductive studies on the short neck clam Paphia malabarica (Chemnitz) from Dharmadom Estuary, Kerala, India

Maturation and spawning of the short neck clam Paphia malabarica was studied from Dharmadom Estuary, in northern Kerala, India. The breeding season was from October to February, with peak spawning in November and December. Sexual activity commenced from March onwards and lasted till September. The peak somatic period was from February to April when more numbers of indeterminates appeared in the population. There was not much difference in the size at maturity (Lm) for females and males; Lm was estimated to be 20 mm for females and 22 mm for males. Chi-square test indicated that the sex ratio differed significantly (p<0.01) from the theoretical 1:1 ratio, only in the month of May. The abundance of mature clams showed positive correlation with salinity and negative correlation with temperature

Evidence-based service modules for a sustained home visiting program

The Centre for Community Child Health (CCCH) at the Murdoch Childrens Research Institute and the Royal Children’s Hospital has undertaken two literature reviews to inform the design of a sustained home visiting program for vulnerable families with young children; the program is now known as \u27right@home\u27. This project is being led by a collaboration between three organisations: The Australian Research Alliance for Children and Youth (ARACY), CCCH, and the University of New South Wales. The first literature review undertaken by CCCH (Sustained home visiting for vulnerable families and children: A review of effective programs (McDonald et al., 2012) (hereon in referred to as the Home visiting review of effective programs) sought to answer the question ‘what works in home visiting programs?’ The conclusion reached was that it was not possible to answer the question definitively, either because the evidence regarding the ‘components’ of home visiting programs is contradictory or contested, or the evidence is not available. As the home visiting review of effective programs focused on what was delivered (ie. the efficacy of different manualised programs), rather than how services were delivered (ie. the effect of the manner in which services were delivered and the nature of the relationships established between service providers and parents), a second literature review was undertaken: Sustained home visiting for vulnerable families and children: A literature review of effective processes and strategies (Moore et al., 2012) (hereon in referred to as the Home visiting review of effective processes and strategies). The home visiting review of effective processes and strategies identified converging evidence from a number of sources to support the idea that the process aspects of service delivery matter for outcomes – how services are provided is as important as what is provided. A number of key elements of effective service delivery processes have been repeatedly identified in the research literature and these represent the threshold features or bedrock on which all services should be based: if services are not delivered in accordance with these process features, then efforts to change people’s behaviour will be less effective (Moore et al., 2012). The evidence also indicated that the identification of goals, and of strategies to achieve these goals, needs to be done in partnership with parents. However, while the ultimate choice of strategies should be made by parents, the strategies on offer used must be evidence-based. Therefore, service providers should be able to draw on a suite of evidence-based strategies to address the range of challenges that parents face in caring for their children (Moore et al., 2012). In the light of the findings of this second literature review, it was decided that the right@home home visiting program would not involve the delivery of a manualised program. Rather, service delivery would be based on the processes of effective engagement and partnership, while the content of the program would take two forms: standard modules that are delivered to all participants, and e.g. information on the stages of child development), and evidence-based ‘service modules’ (i.e. specific strategies) that could be deployed to address issues that are of particular concern to individual parents.&nbsp; Related identifer: ISSN 2204-340

A MEMS BASED MICROWAVE PIXEL FOR UWB RADAR BASED 3-D DIAGNOSTIC IMAGING

A MEMS-based microwave Pixel has been developed for use with an Ultra-wideband (UWB) radar probe for high-resolution 3-D non-contact, non-ionizing tomographic diagnostic imaging of the thorax. In the proposed system, an UWB radar transmits a 400 ps duration pulse in the frequency range of 3.1 GHz to 5.1 GHz. The transmitted pulse penetrates through the tissues and is partially reflected at each tissue interface characterized by a complex permittivity change. A suitable microwave lens focuses the reflected wavefront on a 2-D array of MEMS-based microwave Pixels to illuminate each Pixel to a tiny 2-D section of the reflected wavefront. Each Pixel with a footprint area of 595 x 595 μm2 is designed to have 144 parallel connected microfabricated inductors, each with an inductance of 12.439 nH, and a single 150 μm×150 μm microfabricated deformable diaphragm based variable capacitor to generate a voltage which is the dielectric signature of the respective tissue section. A 2-D array of such Pixels can be used to generate a voltage map that corresponds to the dielectric property distribution of the target area. The high dielectric contrast between the healthy and diseased tissues, enable a high precision diagnostics of medical conditions in a non-invasive non-contact manner. This thesis presents the analytical design, 3-D finite element simulation results, and a fabrication process to realize the proposed microwave imaging Pixel. The proposed Pixel with total inductance of 86.329 pH and capacitance tuning range of 1.68:1, achieved a sensitivity of 4.5 aF/0.8 μA.m-1 to generate tomographic coronal imaging slices of human thorax deep upto 4.2 cm enabling a theoritical lateral resolution of 0.59 mm

Primary schools as community hubs: a review of the literature

Considerable work has been undertaken over several years to establish primary schools as community hubs in the City of Hume through the Hubs Strategy Group for the Hume Communities for Children Initiative and, more recently, the Supporting Parents Developing Children project. This work has highlighted the need for a primary school community hub toolkit. The purpose of this review is to inform the development of a resource (e.g. a toolkit) that can be used by other schools so that they can also establish themselves as community hubs. An agreed definition of schools as community hubs within the literature has not been reached. Rather, the notion of schools as community hubs seems to be understood in a variety of ways. For the purposes of this review we will draw on the definitions provided by Black (2008) and the Hubs Strategy Group for the Broadmeadows Communities for Children Initiative (2009). Black (2008) describes hubs as involving \u27collaboration between school education systems and the other sectors (community, business, local government and philanthropy) to support the learning and wellbeing of young people, especially those facing disadvantage\u27 (p. 6). These collaborations can range from sharing, co-locating or joint use of physical facilities, through to schools as the centre of a hub or precinct that offers multiple services for the whole community. In the City of Hume, the Hubs Strategy Group have conceptualised a hub as, a welcoming place for families that engages key service providers to work collaboratively. A hub can be a single location or a network of places working together to provide services, such as schools, kindergartens, maternal and child health, and other relevant agencies. Hubs facilitate connections between key services and professionals and represent a paradigm shift in the planning and practice of service provision. Services and their staff are required to rethink existing practice to move to an inclusive practices framework at a professional and community level. &nbsp

Electronic control of elastomeric microfluidic circuits with shape memory actuators

Recently, sophisticated fluidic circuits with hundreds of independent valves have been built by using multi-layer soft-lithography to mold elastomers. However, this shrinking of microfluidic circuits has not been matched by a corresponding miniaturization of the actuation and interfacing elements that control the circuits; while the fluidic circuits are small (~10–100 micron wide channels), the Medusa's head-like interface, consisting of external pneumatic solenoids and tubing or mechanical pins to control each independent valve, is larger by one to four orders of magnitude (mm to cm). Consequently, the dream of using large scale integration in microfluidics for portable, high throughput applications has been stymied. By combining multi-layer soft-lithography with shape memory alloys (SMA), we demonstrate electronically activated microfluidic components such as valves, pumps, latches and multiplexers, that are assembled on printed circuit boards (PCBs). Thus, high density, electronically controlled microfluidic chips can be integrated alongside standard opto-electronic components on a PCB. Furthermore, we introduce the idea of microfluidic states, which are combinations of valve states, and analogous to instruction sets of integrated circuit (IC) microprocessors. Microfluidic states may be represented in hardware or software, and we propose a control architecture that results in logarithmic reduction of external control lines. These developments bring us closer to building microfluidic circuits that resemble electronic ICs both physically, as well as in their abstract model

Sustained home visiting for vulnerable families and children: a review of effective processes and strategies

Parenting young children has become a more complex and stressful business, especially for those families in our community with the least resources (Grose, 2006; Hayes et al, 2010; Poole, 2004; Richardson &amp; Prior, 2005; Trask, 2010). A widening gap exists between families that function well and those that are vulnerable. The paradox of service delivery for children and families is that vulnerable families – that is, those families with the greatest needs – are also the least likely to be able to access those services (Ghate &amp; Hazel, 2002; Fram, 2003). A range of barriers exist for vulnerable and at risk families in making use of services (Carbone et al, 2004). One of the key barriers to vulnerable families accessing services is that many find it difficult to relate to the formal service system and are easily alienated by practices others find acceptable. Research regarding parents’ experiences of support services suggests that parents want services where they are simultaneously cared for and enabled in their role as parents, and to receive services characterised by empathy, competence, functionality, respect, flexibility and honesty (Attride-Stirling et al, 2001; Winkworth et al, 2009). Vulnerable parents fear a loss of autonomy in their interactions with support services and want services that are non-judgemental and that provide continuity of care (Ghate &amp; Hazel, 2002; von Bultzingslowen, 2006). In addition to the barriers faced by vulnerable and marginalised families in accessing services, the system does not work in an integrated or coherent fashion to ensure that all children and families needing support receive it. Furthermore, the vast majority of services for children and families in Australia do not have an outreach function, that is, a means of engaging these vulnerable and at risk families who are in need of support but use services inconsistently or not at all. In short, the service system was not designed to meet the needs of vulnerable families within the context of a rapidly changing social and economic climate. Therefore, many families requiring support are not receiving it. Related identifier: ISSN 2204-340
