See the solar simulator in action in this video : Sun in a box, a state-of-the-art solar simulator How does the solar simulator work? The new Varennes solar simulator addresses this need by allowing researchers to flash test commercial PV panels with areas up to three square metres. Module-scale solar simulators are a regular feature of industrial production lines in Quebec and Ontario, but few are available to the PV research community in Canada. Solar simulators can be divided into two categories depending on their illuminated area: a tabletop device illuminates an individual cell a few centimetres in size, whereas a much larger module-scale system illuminates an entire PV panel. This performance information also helps developers as they design their systems. Understanding how these products perform in a controlled environment is essential for meeting national and international standards. But for CanmetENERGY researchers and engineers, the new simulator provides the wide range of capabilities they need to continue assessing the long-term performance of PV systems under the special conditions of our Canadian climate. The Varennes lab has been measuring PV module performance since 1993. Measuring performance: the Canadian climate factor “New standards for measuring PV performance are being defined as new technologies emerge,” says Christopher Baldus-Jeursen, a research officer at CanmetENERGY in Varennes.Ī large solar panel is evaluated prior to testing. Now, researchers across the country can directly assess how the specifications provided by solar panel manufacturers compare with actual performance under controlled laboratory conditions. To help answer these questions, and more, Natural Resources Canada added a new state-of-the-art large-scale solar simulator to CanmetENERGY’s PV testing facility in Varennes, Quebec. But how well will these new systems complement the energy grid? How well do these panels really perform? What are the special requirements for our northern climate? It’s no wonder photovoltaic (PV) solar technology is quickly gaining ground in Canada as new products enter the market and ever-larger systems are being built. At the top of many lists is the need to reduce greenhouse gas emissions. Solar power is an increasingly popular form of renewable energy technology for a number of reasons. Watch a demonstration of the hybrid solar cell.By Allison De Toni, Natural Resources Canada, Ottawa, and Passy Longuet, CanmetENERGY in Varennes, Quebec The authors acknowledge funding from the National Research Foundation of Korea, the Pioneer Research Center Program and the Active Polymer Center for Pattern Integration. The efficiency of all components working together was more than 20 percent higher than the solar cell alone. With that boost, the system could operate an LED lamp and an electrochromic display. Below that, they added a pyroelectric thin film and a thermoelectric device, both of which convert heat into electricity. The researchers layered a dye-sensitized solar cell on top of a PEDOT film, which heats up in response to light. Eunkyoung Kim and colleagues turned to a clear, conductive polymer known as PEDOT to try to accomplish this. One approach is to hybridize solar cells with different materials to capture more of the sun’s energy. Scientists are working to change this using various methods. Solar cells today are getting better at converting sunlight to electricity, but commercial panels still harvest only part of the radiation they’re exposed to. They report on their device, which produces a voltage more than five times higher than other hybrid systems, in the journal ACS Nano. The films convert the light that goes unused by the solar cell into heat and then converts the heat into electricity. Scientists have developed a new hybrid, solar-energy system that harnesses the full spectrum of the sun’s radiation by pairing a photovoltaic cell with polymer films.

These included the development of the “wild,” natural-appearing English garden in contrast to the geometric vistas of the French formal garden the graveyard school of English poetry of the 1740s, with Edward Young’s and Thomas Gray’s melancholy evocations of sorrow, bereavement, death, and decay Samuel Richardson’s Pamela (1740) and other sentimental novels that exploited the reader’s capacity for tenderness and compassion the “novel of sensibility” of the 1760s, with its emphasis on emotional sensitivity and deeply felt personal responses to natural beauty and works of art the Sturm und Drang movement in Germany (1770–80), in which J.W. The new emphasis on genuine emotion can be seen in a whole range of Pre-Romantic trends. He also introduced the idea that the free expression of the creative spirit is more important than strict adherence to formal rules and traditional procedures. Rousseau introduced the cult of religious sentiment among people who had discarded religious dogma, and he inculcated the belief that moral development was fostered by experiencing powerful sympathies. He emphasized the free expression of emotion rather than polite restraint in friendship and love, repudiated aristocratic elegance and recognized the virtues of middle-class domestic life, and helped open the public’s eyes to the beauties of nature. This new emphasis partly reflected the tastes of the growing middle class, who found the refined and elegant art forms patronized by aristocratic society to be artificial and overly sophisticated the bourgeoisie favoured more realistic artistic vehicles that were more emotionally accessible.Ī major intellectual precursor of Romanticism was the French philosopher and writer Jean-Jacques Rousseau. Chief among these trends was a shift in public taste away from the grandeur, austerity, nobility, idealization, and elevated sentiments of Neoclassicism or Classicism toward simpler, more sincere, and more natural forms of expression. Pre-Romanticism, cultural movement in Europe from about the 1740s onward that preceded and presaged the artistic movement known as Romanticism ( q.v.).

They were placed in trading posts or forts to await the six- to twelve-week Middle Passage voyage between Africa and the Americas during which they were chained together, underfed, and kept in the ship's hold by the thousands. The most common means of enslaving an African was through abduction. Jamaican maroons are also from South America, Central America and Latin America of Spanish descendants who are non-Africans.Īfricans were captured in wars, as retribution for crimes committed or by abduction and marched to the coast in "coffles" with their necks yoked to each other. During the period of British rule, slaves brought into Jamaica were primarily Akan and Igbo, some of whom ran away and joined with Maroons and even took over as leaders. When the English invaded Jamaica in 1655, many of them fought with their Spanish masters, who gave them their freedom, and then fled to the mountains, resisting the English colonial administration for decades, becoming known as Maroons. The first Africans to arrive in Jamaica came in 1513 from the Iberian Peninsula. The ethnogenesis of the Black Jamaican people stemmed from the Atlantic slave trade of the 16th century, when enslaved Africans were transported as slaves to Jamaica and other parts of the Americas.

However, it's very much got its own bloody flavour. Neat, right? It follows a similar structure to Valheim, in that you've got to gather resources, power up, and take on a multitude of bosses. If you thought that was a real combo of genres, then get this: you play as a vampire. V Rising is an early access survival game with a hint of MMORPG and made by the Battlerite devs. Seriously, it's a brilliant time sink that has all the staples of a good survival game and then some. The charming PS1 aesthetic, the way you can't just stick a fire in an enclosed space and expect the smoke to magically dissipate, the bees and their happiness. You're dropped into a beautiful forest biome filled with boar and little goblin dudes, before you'll need to venture out into dark woods and plains teeming with massive ogres and horrid, overgrown mosquitoes.įor a game that's still in early access, it's not only rich in things to conquer, but the little details too. Purgatory is actually quite nice – early on, at least. To do so, you'll need to gather up resources, build yourself some nice gear, and beat a handful of big baddies scattered across the land. Valheim is a Nordic delight where you and up to ten bearded buds attempt to break out of procedurally generated purgatory. So go ahead - choose your poison.Īlternatively, if you're exhausted from prising a wolf's mouth from your neck, you might want to watch the splendid video version of this list instead. Whether that hostility takes the form of extreme weather, horrid beasts, or the accumulation of noxious waste gases in an asteroid colony, is entirely dependent on your personal tastes. But we've chosen a set which, at their very hearts, feel like they're about keeping yourself - or others - alive in the face of a hostile universe. That's obviously a pretty key concept to a lot of PC games. There are games on this list which have barely anything in common with each other, beyond the fact that the player must y'know, survive. It's worth noting that we're being pretty broad with our definition of "survival", here, as we wanted to offer something slightly different from a big list of first person wilderness games where a) you get hungry and b) stuff clips through walls all the time. It's not exhaustive, but it'll certainly give you enough fishing, crafting and wolf-avoiding to keep you busy for a good while. How, then, can you pick out the gems from this big pile of detritus? Easy we've made a list of the best survival games. More still were overlooked for high levels of jank in their early days, but have since grown into beautiful things thanks to regular updates. A good few of them were brilliant many, many more were not. For a while back in the late 2010s, you couldn't seem to move online for the sheer number of early access survival games lying around the place. You can take BART, you can take AC Transit, you can park right there and walk a few feet and you’re inside the arena.

A large percentage of project materials will be transported down the river to ease road congestion, emissions and disruption throughout the duration of the project. Using Building Information Modelling (BIM), we will test and simulate construction before works start on site for safe and efficient delivery. This unique infrastructure project, which is the largest ever undertaken by the UK water industry, is another example of the part we are playing in 21st Century engineering. Works will include design, construction, commissioning and maintenance for a two to five year period following construction completion. Working in a three-way equal joint venture alongside Morgan Sindall and BAM Nuttall, we will deliver the £416 million, seven kilometre ‘West’ section of the overall 25km Thames Tideway Tunnel.įrom Acton in West London to Wandsworth in South West London, the project will incorporate seven separate work sites along the route. It will also tackle the issue of discharges of untreated sewage that currently enter the River Thames on a regular basis. Running underneath the River Thames, the new tunnel will ensure the capital’s sewerage system is fit to support its projected population for at least the next 100 years. We are helping to construct the west section of the Thames Tideway Tunnel – London’s new ‘super sewer’.

Mongodumb normally creates a binary export of the selected contents. In this case one can opt to use some coordinated backup and restore processes that maintain the atomicity guarantees of transactions across shards such as MongoDB Cloud Manager, MongoDB Ops Manager and MongoDB Cloud Manager. Mongodump cannot be used for a sharded cluster with sharded transactions in progress especially for versions later than 4.2 due to the fact that mongodump does not maintain the atomicity guarantee of transactions across the shards. It is also possible to have partial backups based on a collection, query, changing a replica set storage engine to a standalone or syncing from production to development environment. mongodumb usage ranges from three angles:įor a complete backup and recovery strategy, mongodump is used alongside the mongorestore tool whereby the latter is used in the restoration process. It can also be downloaded as a separate tool from the MongoDB Download Center. It is used in creating binary exports of the database contents. Mongodump is a utility bundled with the MongoDB database. In this article, we will only discuss the mongodumb utility, what it entails, how to perform and recovery using this utility and lastly what merits and disadvantages is it associated with. MongoDB Management Service (MMS) which is a fully managed cloud service that provides a continuous backup for MongoDB.Įvery approach has its pros and cons dependending on the complexity of implementation, Recovery Time Objective, Recovery Point Objective and cost.Filesystem snapshots whereby data is collected from the database files and then stored in another cloud centre.mongodumb, a utility bundled with the MongoDB itself.In the end, this can provide directions towards fixing application errors that are leading to such. Besides, backups may be created to ensure a company is compliant with organizations and government regulations that may dictate the need to access critical and essential business data after any technical outage.īackups can also be used to ensure data integrity and consistency through close comparison of the previous backups with the current database data. Database backups help administrators to restore the database to its operational state along with its data logs. Backups are achieved through database replication using either database utilities or some external setups. Restoration of the operational database is only possible if there is a backup in place. Database backup for any organization should be an important undertaking for ensuring business continuity in any case of database catastrophe. |
