As a precursor to analyzing data with SAS, you first extract data from Oracle and transform this data into SAS data sets. In several sectors, it is very common to store data in Oracle database system and analyze and present the data using the SAS system. ![]()

The music is what you’d expect, the usual electronica, but it all comes together as a package and actually Scintillatron 4096 is reasonably swish on the PS4. On the one hand the enemy design is very basic and the backdrops aren’t particularly impressive but the game does have a stylish, clean look to it with the transitions between the levels looking particularly good. When it comes to presentation, the game is quite a mixed bag. Not for the shooting action as such but because you know your comboing can improve and with the game’s weighty trophy list, there’s always another trophy just around the corner if you can get it. We mentioned Ikaruga in the first paragraph and mainly that’s down to the colour-based combo system on offer but Scintillatron 4096 also shares another trait with Treasure’s famed shoot ’em up and that’s the fact that the game’s base difficulty is a little at odds with the scoring system because, pretty quickly in, the game’s difficulty will lead you to start focusing on survival way more than point-gathering.īetter players than us will thrive though and we need to practise and Scintillatron 4096 is a game that is addictive enough to keep you coming back. The action feels too staid, the firepower a bit too weedy but the scoring system does work really well and makes this a much more captivating title than we first thought. As a straightforward twin-stick shooter, this wouldn’t really cut it. reward mechanics do make this more than the sum of its parts. It’s a different approach to this genre and it takes quite a few goes to get used to but when you do, the risk vs. Indeed that goes for the whole game really. Likewise, the laser (which penetrates multiple targets) is also too risky to use if you want top points as there is a good chance you’ll accidentally catch an enemy of the wrong colour if you aren’t incredibly diligent with it. Normally in a twin-stick shooter a three-way gun is a very welcome addition to your arsenal but here it’s only good for screen-clearing but won’t do your scoring any favours. The game also throws plenty of power-ups (and downs) at you and these are very much a mixed bag. Enemies in the game generally take a fair amount of damage and so you’ll really have to manage them as much as you do your combos. ![]() Also, as the levels progress you’ll have additional enemies and threats to deal with during normal play which mean you can’t just stick to combo building. Instead of spewing out as many bullets as possible, you now have to be more of a sniper (especially if you want the end of level bonuses for perfect play and finishing the level with ten seconds or more left on the clock.Ī clock? Yep, there’s a time limit on each level and if you haven’t cleared the screen, enemies will spawn in and start to hunt you down more aggressively so you can’t afford to take your time. This is where the game feels like an entirely different proposition to usual twin-stick shooter. You’ll lose your combo if you accidentally shoot the other colour and so you’ll need to be very picky with your shots if you want to trouble those leaderboards. The game has trophies requiring you to combo 50 and then 100 enemies but each of the game’s levels has around 25 enemies in there so you’ll have to stretch it out over multiple levels. A combo is built by shooting enemies of the same colour. ![]() The aim of the game here isn’t just to destroy any threats to your three lives but rather there is an emphasis here on score chasing and to do that you need to ‘combo’ your way through levels. There are no other controls to worry about and you’ve really only got eight directions of firing rather than the usual 360 degrees. ![]() You’ll be controlling the action in the usual way with movement mapped to the left stick and firing mapped to the right (or the DualShock’s face buttons but for sure don’t do that). However, this is a much more organised and considered shooter which has elements of Ikaruga in it as well as the more standard gameplay mechanics you’d expect. While the genre dates back to Robotron 2048 (which is clearly an inspiration for this game just judging by its title), it got popularised by Geometry Wars and aesthetically Scintillatron 4096 shares a few things in common with that game. Scintillatron 4096 is a twin-stick shooter from Dorset-based devs kFunction and it’s not exactly what you might expect.

Using statistics is one of the simplest methods for identifying the main keywords and key phrases within a text. In this section, we’ll review the different approaches to keyword extraction, with a focus on machine learning-based models. ![]() From simple statistical approaches that detect keywords by counting word frequency, to more advanced machine learning approaches that create even more complex models by learning from previous examples. There are different techniques you can use for automated keyword extraction. But the best thing about keyword extraction models is that they are easy to set up and implement. It also provides actionable, data-driven insights to help make better business decisions. Keyword extraction can automate workflows, like tagging incoming survey responses or responding to urgent customer queries, allowing you to save huge amounts of time. This includes emails, social media posts, chat conversations, and any other types of data that are not organized in any predefined way. Keyword extraction simplifies the task of finding relevant words and phrases within unstructured text. You can perform keyword extraction on social media posts, customer reviews, surveys, or customer support tickets in real-time, and get insights about what’s being said about your product as they happen and follow them over time. You don’t have to deal with inconsistencies, which are common in manual text analysis. Keyword extraction acts based on rules and predefined parameters. Automating this task gives you the freedom to concentrate on other parts of your job. Yes, you could read texts and identify key terms manually, but it would be extremely time-consuming. Some of the major advantages of keyword extraction include: ScalabilityĪutomated keyword extraction allows you to analyze as much data as you want. Whatever your field of business, keyword extraction tools are the key to help you automatically index data, summarize a text, or generate tag clouds with the most representative keywords. In the academic world, keyword extraction may be the key to finding relevant keywords within massive sets of data (like new articles, papers, or journals) without having to actually read the entire content. What percentage of customer reviews are saying something related to Price? How many of them are talking about UX? These insights can help you shape a data-driven business strategy by identifying what customers consider important, the aspects of your product that need to be improved, and what customers are saying about your competition, among others. And these words and phrases can provide valuable insights into topics your customers are talking about.Ĭonsidering that more than 80% of the data we generate every day is unstructured ― meaning it’s not organized in a predefined way, making it extremely difficult to analyze and process – businesses need automated keyword extraction to help them process and analyze customer data in a more efficient manner. With keyword extraction you can find the most important words and phrases in massive datasets in just seconds. For example, this online name extractor automatically pulls out names from text.Įxplore other types of keyword extraction when you sign up to MonkeyLearn for free. Other types of keyword extraction include named entity recognition, which involves extracting entities (names, location, email addresses) from text. ![]() Try out this free word cloud generator now to see how you can extract important keywords from your text. The more a word or phrase appears in the text, the larger it will be in the word cloud visualization. ![]() That way, you can easily and automatically see what your customers are mentioning most often, saving your teams hours upon hours of manual processing. Keyword extraction helps you sift through the whole set of data and obtain the words that best describe each review in just seconds. Imagine you want to analyze thousands of online reviews about your product. It’s used to find keywords from all manner of text: regular documents and business reports, social media comments, online forums and reviews, news reports, and more. Keyword extraction uses machine learning artificial intelligence (AI) with natural language processing (NLP) to break down human language so that it can be understood and analyzed by machines. It helps summarize the content of texts and recognize the main topics discussed. Keyword extraction (also known as keyword detection or keyword analysis) is a text analysis technique that automatically extracts the most used and most important words and expressions from a text. ![]() ![]() ![]() To make this statement more quantitative, consider a diffracting object at the origin that has a size a a. It is mathematically easier to consider the case of far-field or Fraunhofer diffraction, where the point of observation is far from that of the diffracting obstruction, and as a result, involves less complex mathematics than the more general case of near-field or Fresnel diffraction. The problem of calculating what a diffracted wave looks like, is the problem of determining the phase of each of the simple sources on the incoming wave front. The fourth figure, for example, shows a comparison of a double-slit pattern with a pattern formed by five slits, both sets of slits having the same spacing between the center of one slit and the next. When the diffracting object has a periodic structure, for example in a diffraction grating, the features generally become sharper.The diffraction angles are invariant under scaling that is, they depend only on the ratio of the wavelength to the size of the diffracting object.(More precisely, this is true of the sines of the angles.) In other words: the smaller the diffracting object, the wider the resulting diffraction pattern, and vice versa. The angular spacing of the features in the diffraction pattern is inversely proportional to the dimensions of the object causing the diffraction.Several qualitative observations can be made of diffraction in general: In the case of light shining through small circular holes we will have to take into account the full three-dimensional nature of the problem. For light, we can often neglect one dimension if the diffracting object extends in that direction over a distance far greater than the wavelength. For water waves, this is already the case, as water waves propagate only on the surface of the water. ![]() The simplest descriptions of diffraction are those in which the situation can be reduced to a two-dimensional problem. Usually, it is sufficient to determine these minima and maxima to explain the observed diffraction effects. If the distance to each source is an integer plus one half of a wavelength, there will be complete destructive interference. If the distance to each of the simple sources differs by an integer number of wavelengths, all the wavelets will be in phase, resulting in constructive interference. That is, at each point in space we must determine the distance to each of the simple sources on the incoming wavefront. Thus in order to determine the pattern produced by diffraction, the phase and the amplitude of each of the wavelets is calculated. Numerical approximations may be used, including the Fresnel and Fraunhofer approximations.ĭiffraction of a scalar wave passing through a 1-wavelength-wide slit Diffraction of a scalar wave passing through a 4-wavelength-wide slit General diffraction īecause diffraction is the result of addition of all waves (of given wavelength) along all unobstructed paths, the usual procedure is to consider the contribution of an infinitesimally small neighborhood around a certain path (this contribution is usually called a wavelet) and then integrate over all paths (= add all wavelets) from the source to the detector (or given point on a screen). Such treatments are applied to a wave passing through one or more slits whose width is specified as a proportion of the wavelength. ![]() ![]() For broader coverage of this topic, see Diffraction.ĭiffraction processes affecting waves are amenable to quantitative description and analysis. ![]() ![]() = 0x0303 Protocol Versionįilters packets based on the TLS record layer’s content type (e.g., handshake, alert, application data).įilters for the Server Name Indication (SNI) extension in the handshake, which is often used to indicate which hostname the client is trying to connect to, especially important for servers hosting multiple domains. you have to define it in the Capture Options.

Particles made of quarks, including protons as well as neutrons, are called hadrons. Each proton is made of two “up” quarks and a “down” quark. Protons may be tiny, but they still can be broken down into even smaller bits of matter. A single proton more, for instance, is the difference between platinum and gold. But when atoms gain or lose protons, they become wholly different elements. When that happens, they become ions of that element. And atoms of the same element can gain or lose electrons. Those different varieties of an atom are called isotopes. Atoms of the same element can have different numbers of neutrons. Oxygen, for instance, has eight protons while gold has 79. The number of protons in an atom determines what element it is. The electrons’ negative charge makes them attracted to the positive protons in the nucleus. That nucleus is surrounded by a cloud of electrons. Along with neutrons, protons form an atom’s core, or nucleus. It is one of the three types of particles that make up atoms. A proton is a particle with a positive electric charge. ![]() |
