With NativeEnvironment, rendering a template produces a native Python type.

But even adding in a line Environment=HOME=/home/username I think this is because the HOME directory isn't being set (xscreensaver looks in ~/.xscreensaver for its configuration). It has been tightly integrated with the Xfce desktop, utilizing Xfce libraries and the Xfconf configuration backend. as peterx14 says here, many of the tutorials for setting up xscreensaver provide incorrect information.

The formula for the volume of a triangular prism is given as Volume of a triangular prismĪ triangular prism is a prism whose cross-section is a triangle. ![]() Let’s discuss the volume of different types of prisms. Where Base is the shape of a polygon that is extruded to form a prism. The volume of a Prism = Base Area × Length The general formula for the volume of a prism is given as Since we already know the formula for calculating the area of polygons, finding the volume of a prism is as easy as pie. The formula for calculating the volume of a prism depends on the cross-section or base of a prism. The volume of a prism is also measured in cubic units, i.e., cubic meters, cubic centimeters, etc. The volume of a prism is calculated by multiplying the base area and the height. To find the volume of a prism, you require the area and the height of a prism. pentagonal prism, hexagonal prism, trapezoidal prism etc. Other examples of prisms include rectangular prism. For example, a prism with a triangular cross-section is known as a triangular prism. Prisms are named after the shapes of their cross-section. By definition, a prism is a geometric solid figure with two identical ends, flat faces, and the same cross-section all along its length. In this article, you will learn how to find a prism volume by using the volume of a prism formula.īefore we get started, let’s first discuss what a prism is. The volume of a prism is the total space occupied by a prism. ![]() Volume of Prisms – Explanation & Examples Synthetic benchmarks are especially useful in the context of large instances where real data is typically unavailable in sufficient size, quantity, or variety. Network models also enable or supplement experimental campaigns as a versatile source of synthetic data with controllable independent variables. In practice, such results tend to be more relevant than worst-case analysis based on pathologic structures that are implausible in applications. Then we can derive realistic formal performance predictions using average-case analysis, smoothed complexity, et cetera. In algorithmics we may, for instance, assume that meaningful inputs are random instances of a suitable network model. Popular models are designed such that we Footnote 1 can expect certain topological properties from a randomly drawn instance: a particularly interesting goal is to reproduce the loosely defined class of complex networks which, among others, encompasses most social networks.īy expressing network models as random graphs, we inherit a rich set of tools from combinatorics, stochastics, and graph theory. These distributions are almost always parametrized (e.g., for the graph size or density) and typically follow implicitly from some randomized construction algorithm. Networks are commonly modeled by so-called random graphs and, therefore, represent probability distributions over the set of graphs . Research into and applications of these models are deeply intertwined with various fields of science. Network models are just that: a mathematical tool to describe and analyze realistic graphs. However, a formal grammar capturing the inner structure of the data expected to be processed is required to provide tailor-made solutions. They are fed by billions of interconnected sensors and computerized personal devices that produce enormous volumes of network data to be exploited.Ĭomputer science provides the means to face this big data challenge. Nowadays, modern computers offer sufficient storage and processing capacity to map out most aspects of human life and the world we inhabit. The practical importance of networks, however, only sky-rocketed with the advent of the information age. As such, humanity is seeking to understand their structures, rules, and implications for centuries (see also Sect. ![]() ![]() Networks are the very fabric that makes societies . In this chapter, we survey the results obtained for these so-called graph generators. As several SPP 1736 projects engineered practical graph algorithms, multiple sampling algorithms for various graph models were designed and implemented to supplement experimental campaigns. While there exist public network libraries with numerous datasets, the available instances do not fully satisfy the needs of experimenters, especially pertaining to size and diversity. From an algorithmics point of view, structural insights into networks can guide the engineering of tailor-made graph algorithms required to face the big data challenge.īy design, network models describe graph classes and therefore can often provide meaningful synthetic instances whose applications include experimental case studies. Network models are developed and used in various fields of science as their design and analysis can improve the understanding of the numerous complex systems we can observe on an everyday basis.

![]() The final version, probably to simplify the story. TOS: "Balance of Terror") as well as the fact that the ship isĮquipped with a cloaking device. Its name and appearance (inspired by the Romulan Bird-of-Prey from Kruge was intended to steal the ship from the Romulans, which explains The Klingon Bird-of-Prey ship type was designed by Nilo Rodis of ILMĪnd was first featured in "Star Trek III: The Search for Spock" as the After the decision to make the villains Klingons, there was then a (removed) sub-plot about the Klingons and the Romulans sharing technology that would explain their visual and technological similarity. Initially the baddies in ST:3 were going to be Romulans. ![]() The Klingon Bird-of-Prey was an updated version of the Romulan Bird-of-Prey from TOS: Balance of Terror. The shape and design of the Klingon ship were modelled on a fictional Romulan bird. George also thought that the sketched male looked somewhat like a football player so he added the twin bulks below the meshes, believing they resembled shoulder pads, and a thin, tiny, brown pipe around the command bulb, as the protective-looking pipe's appearance was similar to a footballer's chin guard. The muscular man's down-turned arms influenced the look of the ship's wings in their attack position and his large, distinctive shoulders and trapezius muscles inspired George to add the wiry meshes on the ship's aft hull. Despite being somewhat surprised by Rodis' guideline of using this sketch as an influence, George was nevertheless inspired by the appearance of the pictured man while building the original prototype model. One of the sketches that Nilo Rodis gave Bill George, to help George in constructing the first prototype studio model of the ship, featured the image of a muscleman. ![]() Ultimately, aspects of different designs were mixed to create a hybrid of the various looks. It seems like Bill George, the model designer, took inspiration from both the muscleman sketch and the physique and equipment of a football player. 4 now features the "muscleman" sketch that inspired the ship's design. Of course, both stances would have a similar look to them, so it may have been a bit of both, depending on who happened to be interviewing him at the time. So, while I could swear I remembered him talking about football players, it could have been body-builders. I had never seen Star Trek before, I didn't know there was already a bird of prey. The Klingon Bird of Prey was inspired by body builders' shape when they flex their muscles like crab. In fact, you are credited as the inventor of the distinctive look of the Klingon Bird of Prey starship. (Photos aren't the greatest, but these are the best I could find.)Īctually, I just found a snippet from an interview with the designer here:īesides Star Wars, you were also involved with Star Trek. You can see this best from a head-on view, though you probably wouldn't live long enough to tell anyone about it. I can't find a source to cite this unfortunately, but I recall watching a "behind-the-scenes" show years ago where someone (presumably the designer) mentioned that its major inspiration was a football player, with his head down/forward and padded shoulders. |
