![]() (Turns out there is!) What causes under-eye dark circles?Ĭontrary to popular belief, dark circles are not just the result of being tired. So, let’s explore the cause of under-eye circles and figure out just what they really mean-and if there’s anything we can do about them. There’s actually a bit more to dark circles than simply whether or not we’re well-rested. Though they’re commonly thought of as the result of not sleeping well enough, some people find that no matter how much sleep we get, those pesky dark circles are still there!

![]() ![]() ![]() The CPS architecture of Jay Lee 5C allows data acquisition, system administration, and control responses for the adoption of different reconfigurations. This metamodel enriches CPS models with high-granularity graph-based skill descriptions, which, in combination with the appropriate manufacturing process descriptions, allow automatic matching for production planning and further simulation and ontimization.read more read lessĪbstract: Cyber-Physical Systems (CPS) are commonly used for the development of Industry, specifically the Industry 4.0 paradigm, allowing the connection of the virtual world with the physical world and the use of information technologies. In this paper, a semantic metamodel for CPS is presented. This description should allow the entirely automatic generation of production cell models through the matching of CPS skills and product requirements. To allow automatic matching from product descriptions to specific CPSs, a new approach to CPS description is necessary. This manual step hinders the automatic production cell model generation based on the product requirements. Instead, production cell components are manually assigned to the manufacturing processes, which are required for the product. Semantic information in the skills description usually is completely absent or present only to the extent, which is not enough to match the corresponding components to the product requirements and necessary production processes. However, existing solutions for CPS description models contain mainly skills and functionalities of the component from a task-oriented perspective to achieve platform-independent code generation for the components control. The model-based systems engineering (MBSE) approach promotes increased reusability of component models and allows an automatic generation of the system of interest model and its validation through simulation, which results in a shorter design phase. Digital representation of those components through the definition of the corresponding description models starts in the early design phase of the engineering process. This paper also shows a way to simplify the evaluation for dynamic system by improving the composability and compositionality of the subsystem.read more read lessĪbstract: Digitalization slowly but steadily transforms the modern production cells by adding an IT layer to their structure, which, subsequently, leads to the use of cyber-physical systems (CPS) as production cell components. The simulation results show that the one-order feedback strategy has high reliability, scalability and stability against the complexity of decision and random failure. Further, two decentralized decision process strategies are proposed based on our framework, and we compare the reliability with the static strategy and the centralized processing strategy. We provide constraints and seven patterns for the composition of reliability and process time requirements. To simplify self-management, a self-similar recursive actor interface is proposed for decision (actor) composition. ![]() Based on the relative time solution, a formal reference framework is introduced for self-managed CPSs, which includes a compositional FSM-based actor model (subsystems of CPS), actor-based advice and runtime decomposable decisions. To guarantee the consistent observation of event orders for causal reasoning, this work first proposes a relative time-based method to improve the composability and compositionality of the timing property of events. In this paper, a formal compositional framework is proposed to systematically improve the dependability of the decision process. Such dynamic adaptation behavior introduces systemic challenges for CPS design, advice evaluation and decision process arrangement. To provide continuous and high quality services, a self-managed CPS should automatically reconstruct itself to adapt to these changes and recover from failures. Abstract: Cyber Physical Systems (CPSs) need to interact with the changeable environment under various interferences. ![]() ![]() ![]() Takara: Fight! Super Robot Lifeform Transformers 09 Prowl.IGA: Transformers Bluestreak (no face paint).e-HOBBY: Collector's Edition Streak (anime version).Takara: Fight! Super Robot Lifeform Transformers 08 Streak.Patent info, price guide, and further reading on Prowl at.This mold was retooled to create the simultaneously-released Bluestreak, and again for Smokescreen. See below for individual entries on these releases. Prowl's toy has been reissued as part of the Classic Heroes line in 1990, The Transformers Collection in 2002, and the Commemorative Series in 2003. There was also a widely available running change variant (or just factory error) that left out the black paint on his car hood. Also in 1985, the Mexican release by Hasbro licensee IGA featured an even more more startling variation: this release of the figure rendered his helmet, arms, and boots black, plus his English "POLICE" decals became a Spanish "POLICIA". Meanwhile, the Joustra version's sticker sheet, which did still feature those markings for the robot shoulders, was replaced with the standard Hasbro Transformers version for the MB release. Unlike the aforementioned early US Transformers version, the Joustra Diaclone figure already lacked both the red "R" and the "Diaclone" markings on the factory-applied stickers for the car hood and doors. This "MB" version of Prowl was in reality literally a repackaged and rebranded Diaclone figure originally intended to be released by European Takara licensee Joustra. ![]() In Europe, Prowl was released in 1985, in packaging branded not with the regular "Hasbro" logo, but rather that of newly-acquired Hasbro subsidiary Milton Bradley, which possessed the necessary facilities and infrastructure to distribute Transformers toys in continental Europe. In 1985, a heat-activated rubsign was added to the front of Prowl's hood. The Chinese 1989 release, which was produced around the same time as the European "Classic Heroes" version (see below), again featured the "Diaclone" markings, this time not only on the hood but also on the doors. This was eventually amended by a running change that dropped the "Diaclone" markings. While all releases and variants of Transformers Prowl omit the red "R", a very early production run of the "pre-rub" US release of Prowl still retained the "Diaclone" marking on the hood (but not on the doors or the shoulders!). The original Takara Diaclone release of the figure featured a red "R" inside the yellow police star, as well as the word "Diaclone", as part of the factory-applied police badge stickers that decorated the car hood and doors, as well on the stickers for the robot's shoulders that were part of the included sticker sheet. The spring-loaded firing mechanism for these launchers was disabled by Hasbro, but remained intact on the Takara release of the figure. In robot mode, he is armed with a silver-chromed hand-held acid pellet gun, and two shoulder-mounted missile launchers. He transforms into a Datsun 280ZX Turbo sports car (known in Japan as a "Fairlady Z") decorated in Japanese police car livery, though with "Highway Patrol Police" markings in English (which had already been present on the original Diaclone version). ![]() Originally a Diaclone "Police Car Fairlady Z", Prowl was one of the original assortment of Autobot Cars released in 1984. ![]() ![]() The warmer-white (3000K & 4000K) color is similar in hue to an incandescent and provides a more gentle light, which we see requested a lot for applications in the home. The standard density has 30 LEDs per meter and the high density has 60 LEDs per meter.Ĭolor Options: The 5050 SMD LEDs inside the strips are available in three different white color temperatures and RGB. There are two variations of this strip, a standard density and high density. The beginning of each strip includes a 6-Inch long 2.1mm female power plug that connects to either the dimmer or the battery holder, as described earlier. The sections of strip are 20-Inches long and flexible enough to bend and stick around curves. On the bottom side of the strip is a double-sided thermal 3M tape for easily mounting them to a surface. They are sealed in a protective clear silicone epoxy making them durable and waterproof (IP65 rated). The strips, again, require 12V dc, but lets talk about the other characteristics and features that make these the ideal choice. Now that power is solved, lets talk about… Battery powered LED light strips However, these run times are based on the LEDs operating at full power, but many of you, like me, will add the option for dimming, which means you can run the strips at a lower output and get more run time. The LEDs never completely went out, but did get dim enough after that amount of time that they wouldn’t be useful without recharging or replacing. The respective run time from 8AA Duracell batteries is 30+ and 15+ hours. ![]() The strips options, which we also will go over in more detail later, come in either standard or high density. Run Time: 8AA batteries provide lots of juice and ran these strips much longer than we expected, but because we offer two different output LED strips the run time will vary depending on which one you choose. ![]() It can be used with standard AA batteries or rechargeable batteries, and is completely enclosed with double-sided mounting tape on one side with a 6-inch long male 2.1mm power plug that can be quickly disconnected from the strips or dimmer (more on dimming options later). ![]() This battery holder measures 4.76” (L) x 2.31” (W) x 0.65” (H) and includes an on/off switch. Kit component 1: 8AA Battery Holder with Switchīattery Holder: So, we power the LED strips with AA batteries inside a 8AA Battery Holder. ![]() ![]() ![]() Caution!

The function aes() is used to specify aesthetics. To demonstrate how the function ggplot() works, we’ll draw a scatter plot. Geometry: the type of plots ( histogram, boxplot, line, density, dotplot, bar, …).Aesthetics: used to specify x and y variables, color, size, shape, ….Recall that, the concept of ggplot divides a plot into three different fundamental parts: plot = data + Aesthetics + geometry. This section describes briefly how to use the function ggplot(). The more powerful and flexible function to build plots piece by piece: ggplot().The quick and easy-to-use function: qplot().Many examples of code and graphics are provided.Īs mentioned above, there are two main functions in ggplot2 package for generating graphics: This document describes how to create and customize different types of graphs using ggplot2. ggsave(“plot.png”, width = 5, height = 5), which saves the last plot in the current working directory.last_plot(), which returns the last plot to be modified.The generated plot can be kept as a variable and then printed at any time using the function print().Īfter creating plots, two other important functions are: The ggplot() function is more flexible and robust than qplot for building a plot piece by piece.qplot() is a quick plot function which is easy to use for simple plots.Two main functions, for creating plots, are available in ggplot2 package : a qplot() and ggplot() functions. Geometry corresponds to the type of graphics ( histogram, box plot, line plot, density plot, dot plot, ….).It can also be used to control the color, the size or the shape of points, the height of bars, etc…. Aesthetics is used to indicate x and y variables.The principal components of every plot can be defined as follow: The gg in ggplot2 means Grammar of Graphics, a graphic concept which describes plots by using a “grammar”.Īccording to ggplot2 concept, a plot can be divided into different fundamental parts : Plot = data + Aesthetics + Geometry. J Physiol 589:1861-3.Ggplot2 is a powerful and a flexible R package, implemented by Hadley Wickham, for producing elegant graphics. And the good news is that the people behind Python’s Seaborn and R’s ggplot2 have done the hard work for us. Try adding individual data points and jitter to your next figures, your readers will be grateful. Jitter can easily be added to plotted data to make nice plots like this one and this one. ![]() ![]() The module contains a function called _jitter() that adds jitter to the data to be plotted (I wrote this before I knew about Seaborn!).Ĭreating pretty, informative plots is one of the hallmarks of ggplot2, a plotting system for the R statistical programming language. I have written a small Python module to generate plots for paired data and their difference. The code used to generate this figure is available here. The next two subplots show two ways to add jitter in Python with the Seaborn statistical plotting package. Because the first subplot does not include jitter, it is difficult to tell whether some data points overlap. The following figure has three subplots that all include individual data points. Jitter is simply the addition of a small amount of horizontal (or vertical) variability to the data in order to ensure all data points are visible. This can easily be solved by adding some jitter to the individual points that have the same or similar values. One problem with plotting individual data points is that they can overlap and make it difficult to see all of the data. Using jitter to help readers see your data As highlighted in our previous posts, scientists are encouraged to plot the data used to compute the summary statistics in figures (e.g., Drummond & Vowler, 2011). can be misleading and conceal the nature of the underlying data. Why is showing data important? As previously pointed out here and here, figures with means, standard deviations, standard errors, etc. Scientific figures are at their most informative when they include the individual data used to calculate summary statistics such as means and standard deviations. ![]() ![]() ![]() Adjust the leg pads so that when seated the pads rest against the top of your legs to minimize any movement, locking you in place.Set up a bar (straight bar or wide grip bar) on the cable pulley/lat pull down machine.To do a traditional lat pulldown follow these steps: To finish, you will slowly let the bar travel back to the starting position. Once the bar is just under chin level or at your chest with your elbows at your sides. To perform a lat pulldown you will get into seated position on the cable machine or lat pulldown machine then reach up to grab the bar with both hands using an overhand grip with hands slightly wider than shoulder-width apart.įrom there, you will pull down on the bar by adducting the lats while depressing the scapulae and flexing at the elbows. There are a number of lat pull down variations that employ the use of different equipment and grips but the traditional lat pulldown involves the use of a cable machine and a bar attachment. The lat pull down is a compound movement that primarily targets the lats and is considered to be a vital exercise for developing back strength and increasing overall pulling strength. We’ll also give you 10 of the best lat pulldown variations that you should add to your workout programming. By the time you finish reading, you’ll know how to do lat pulldowns, muscles worked and benefits. This post is a deep dive into the lat pulldown. Almost anytime you walk into a gym you’ll see someone doing lat pulldowns but often times the form and technique is a bit off. Lat pull downs are one of the essential compound exercises for the back as most gyms will have a dedicated machine for this exercise. The lat pulldown is one exercise that should be in everyone’s arsenal if you want a bigger, stronger back and wide lats. ![]() ![]() ![]() Declaring this to be their final battle, Skeletor incinerates He-Man's ally Moss-Man, causing an enraged He-Man to impale Skeletor upon the locking mechanism, exposing Castle Grayskull into its true form as the Hall of Wisdom.
