![]() Bilingual Early Learning & Easy Teaching BENGALIi Books for Kids BENGALIi Language Learning book.> Checkout more books from the author phonetics, the commonly used word in Bengali Help us out - We are a small business, and your brief review could really help us. The last few decades have seen a stretching and exchange of local, regional and national languages, identities, cultures, and economies worldwide as a consequence of globalisation and technology development. Significantly, the languages of the Middle East, Africa, Asia, the Netherlands, Scandinavia, Eastern Europe and Russia have been attracting increasing strategic, commercial and civic attention. Collectively referred to as ‘Languages of the Wider World’ (LWW), these languages are important given the emergence of new centres of capital and cultural accumulation in the 21st century, such as Brazil, Russia, India and China (BRICs). This volume focuses on LWW in use, and on their teaching and learning. It ranges from a highly localized focus (on learners and teachers of Community/Heritage Languages), to broader national and international foci (on policy makers and multilingualism on teachers in primary, secondary and tertiary systems). It aims to inspire researchers and practitioners to work on languages other than the ones that have been the mainstay of the field to facilitate the development of a vibrant and critical community of enquiry in Languages of the Wider World. This book was originally published as a special issue of the Language Learning Journal. Nobel Prize winner Rabindranath Tagore's (1861 - 1941) most beautiful poetry, translated into English, is almost as beautiful as in its native Bengali. Fifty selected poems from Tagore, as well as three original poems. Tagore was native to what is now Kolkota India and Bangladesh.Tagore toured widely throughout the world in an effort to bring Eastern culture to the west and vice-versa. Knald is the world’s first GPU powered solution for generating “bake quality” textures from any 2D source texture.Knald generates textures commonly used to create games, like Normal, Derivative, Displacement/Height, Ambient Occlusion, Concavity and Convexity maps.$100 for individual licence.Additionally, part of the purpose of this book is to help Asian Indian youth and others from India to become familiar with their own rich literary cultural heritage. It can also project the texture of the highpoly model into the lowpoly mesh ( complete texture transfer, even with different topologies ).It includes too an interactive 3D viewer ( with advanced shaders and realtime soft shadows. XNormal is an application to generate normal / ambient occlusion / displacement maps. Well with Algorithm Lab when you create a graphic, most of the time. Now why do I need to generate graphics why cant I just draw them or take a picture. Algorithm Lab, put simply is a procedural graphics application used for generating graphics. Texture Studio is so easy to use, a photograph can be converted to a smoothly. Texture Studio includes a set of integrated tools, all extremely useful for creating high quality seamless textures. Texture Studio is all you need to produce professional quality textures for use in games and tiled backgrounds. ![]() Quixel Suite is a bundle of tools for creating amazing materials for use in realtime applications. It supports ambient occlusion (AO) maps, bump maps, normal maps, and more. ![]() ![]() The normal map generator can also create texture coordinates.Ĭrazybump generates lighting maps from 2D textures. Simply load your low-poly working model, then load your high-poly reference model, click the "Generate Normal Map" button and watch Melody go to town. NVIDIA Melody creates high quality normal maps that make a low-poly model look like a high-poly model. PhotoSculpt Textures is a software that creates 3D models and 3D textures from just two photos of the same subject. PixPlant is a smart texturing app with the best tools to quickly transform a photo into seamless repeating textures and 3D maps.PixPlant includes a smart texturing engine and 3D map editors: save a lot of texturing time with PixPlant!.

If that name is familiar, it’s probably because Rogers just made headlines for a high-score scandal of his own. Mitchell has not verified his score in any of those alternative ways with the exception of a witness by the name of Todd Rogers. Scorekeepers like Young often do accept results performed on MAME, but they typically require independent, in-person verification or live video on a service like Twitch that shows the game and the player all at the same time. MAME’s INP recording capability enables players to rewind their mistakes, continue playing, and then stitch together a final recording that looks like one, unbroken playthrough. Given the playstyle in Billy’s videos, it’s more likely that vanilla MAME’s was abused.” “It’s possible they were recorded in one shot. “While clearly MAME, there is no way to tell exactly how these games were performed,” reads Young’s post. Young considers the evidence against Mitchell conclusive when it comes to falsifying his Donkey Kong platform, but he also suggests that cheating isn’t just possible - it’s “likely.” Now, watch how Mitchell’s footage for this 1.05-million-point run renders in the ladders and then the steel beams just like the MAME version. See how the entire level gets drawn into the game from left to right? This is how the arcade works. ![]() Score chaser Chris Gleed has one of the only direct-feed recording setups for Donkey Kong in the world. See how the ladders render in all at once and then the steel beams blink into existence after that? This is how MAME handles Donkey Kong. Here’s some GIF examples from the breakdown: MAME 0.122 to 0.126 If you slow down footage of Donkey Kong to 1 frame per second, you can see what each of those methods looks like.Arcade draws in the level with a sliding-door effect from left-to-right.MAME renders in huge chunks of a level all at once.MAME and the original Donkey Kong arcade machine, which I’ll just call “arcade,” render Donkey Kong’s visuals differently.The explanation of the evidence is a bit technical, so let me break it down as simply as I can: The primary allegation is that Mitchell played his best Donkey Kong games on the Multiple Arcade Machine Emulator (MAME) while maintaining that he was playing on original arcade hardware. You can read Young’s detailed argument against Mitchell right here. It’s important to realize that my motivations here are all about leaderboard and competitive integrity - this isn’t about Billy in particular and trying to knock him down a peg.” Billy’s status in the gaming world (good or bad) doesn’t affect that. Gaming is a hobby for me and always will be regardless of how this story pans out. “While we both play DK, we’re not direct competitors so I have nothing to gain by knocking him down the leaderboard. “I have no grudges or jealousy toward Billy,” Young told GamesBeat. Now, that portrayal is starting to seem even more accurate, as it could include dishonesty and even cheating. That movie painted Mitchell as a somewhat villainous character standing in the way of Wiebe’s heroic everyman. Mitchell and Wiebe’s battles over the Donkey Kong high score were the subject of the popular documentary film King of Kong: A Fistful of the Quarters. 47 score with his 933,900 result he played in public on an arcade machine in 2004. The professional gamer and hot-sauce magnate now has the No. 20 score with 1.062 million points, right behind his long-time rival Steve Wiebe’s 1.064 million. On Donkey Kong Forum, Mitchell previously held the No. Register today.Ī Donkey Kong fansite has removed three high scores from arcade legend Billy Mitchell after an analysis revealed he likely misled the community about playing on real arcade hardware and that he instead submitted emulator gameplay. ![]() Interested in learning what's next for the gaming industry?

Why not! How about a mage built like a glass cannon who dies if a skeleton sneezes on him but can summon immense destructive power? Do it! This can be both good and bad depending on how clever you are in terms of leveling characters, since the game leaves all the various aspects entirely up to you. While there are four set classes to choose from at the start it’s completely up to you how you develop them. Admittedly the game does revolve around you killing one particular baddy who’s got a certain demonic tendancy, such as a great love for slaughtering entire towns and such, but the Torchlight world doesn’t revolve around any grand mystical conflict. Ok I may have lied slightly about there being no big bad demons. No, amid Torchlight 2’s incredible cartoony art style is a vast world full of steampunk and fantasy influences that are present throughout. Who wants to be involved with battles between two unstoppable forces anyway? Level 100 might seem god-like but unfortunately there’s no “Destroy immortal supreme being” power to even have a hope of contesting those sorts of odds. ![]() In a slight turn away from the traditional fantasy realm of big bad demons vs almost equally big and frightful gods Torchlight 2 instead does away with all that. Is it any wonder then that Torchlight 2, brought to us by the ex-Blizzard North employees that make up Runic Games, have ridden the wave of Diablo’s launch to great success? Oh the game in itself was entertaining but it ultimately felt lacking in a few too many areas for a sequel to one of the greatest action RPGs of all time.

![]() The elements can be subdivided further by more specific properties, such as the composition of the compounds they form. ![]() The elements can also be classified into the main-group elements (or representative elements) in the columns labeled 1, 2, and 13–18 the transition metals in the columns labeled 3–12 and inner transition metals in the two rows at the bottom of the table (the top-row elements are called lanthanides and the bottom-row elements are actinides Figure 2.4.3). We can sort the elements into large classes with common properties: metals (elements that are shiny, malleable, good conductors of heat and electricity-shaded yellow) nonmetals (elements that appear dull, poor conductors of heat and electricity-shaded green) and metalloids (elements that conduct heat and electricity moderately well, and possess some properties of metals and some properties of nonmetals-shaded purple). Other elements are not shiny, malleable, or ductile, and are poor conductors of heat and electricity. For example, many elements appear shiny, are malleable (able to be deformed without breaking) and ductile (can be drawn into wires), and conduct heat and electricity well. Many elements differ dramatically in their chemical and physical properties, but some elements are similar in their behaviors. For the table to fit on a single page, parts of two of the rows, a total of 14 columns, are usually written below the main body of the table.įigure 2.4.2 Elements in the periodic table are organized according to their properties. However, IUPAC recommends that the numbers 1 through 18 be used, and these labels are more common. In the United States, the labels traditionally were Roman numerals with capital letters. Groups are labeled at the top of each column. The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups. Each box represents an element and contains its atomic number, symbol, average atomic mass, and (sometimes) name. A modern periodic table arranges the elements in increasing order of their atomic numbers and groups atoms with similar properties in the same vertical column ( Figure 2.4.2). The modern statement of this relationship, the periodic law, is as follows: the properties of the elements are periodic functions of their atomic numbers. (credit a: modification of work by Serge Lachinov credit b: modification of work by “Den fjättrade ankan”/Wikimedia Commons)īy the twentieth century, it became apparent that the periodic relationship involved atomic numbers rather than atomic masses. Although Mendeleev and Meyer had a long dispute over priority, Mendeleev’s contributions to the development of the periodic table are now more widely recognized ( Figure 2.4.1).įigure 2.4.1 (a) Dimitri Mendeleev is widely credited with creating (b) the first periodic table of the elements. The discoveries of gallium (1875) and germanium (1886) provided great support for Mendeleev’s work. But Mendeleev went one step further than Meyer: He used his table to predict the existence of elements that would have the properties similar to aluminum and silicon, but were yet unknown. Both published tables with the elements arranged according to increasing atomic mass. One such grouping includes lithium \ce also exhibit similar properties to each other, but these properties are drastically different from those of any of the elements above.ĭimitri Mendeleev in Russia (1869) and Lothar Meyer in Germany (1870) independently recognized that there was a periodic relationship among the properties of the elements known at that time. ![]()
