It was during their 3-day stay that they envisioned a new software development model. What is Agile?īefore we give you a definition, let us provide you with a bit of history.īetween February 11-13, 2001, 17 developers with different backgrounds met at the Lodge of Snowbird ski resort in the Wasatch mountains of Snowbird, Utah to vacation and discuss a common model for software development. In between each phase, there is usually a review and sign off process to ensure all goals are met before moving on to the next stage. Maintenance - post-release correct or adaptive measures to improve and update the final product, such as patch updates.Operation/Deployment - the final product or application is considered fully functional and is deployed to a live environment.Testing - the testing of the code using quality assurance engineers and a variety of software tests to root out bugs, errors, and other issues that need to be resolved.Coding/Implementation - the source code developed using the logic, requirements, specification, and processes from the earlier stages. Design - the design specification document that outlines technical design requirements such as data sources, hardware, and the programming language to be used.

Even Bob Team Epic and Hellshake Yano makes a return, which as a newcomer to the seasonal anime rut back in the day, I was in for pleasure, and got more than expected out of it. With Season 2 around, almost the entirety of Season 1 makes a return, sadly omitting the interesting Japan Mignon A-B sided French-Japanese segment with Thibault Tresca in full replacement for the Ikemen-focused B-side, which was underwhelming to say the least. Which is why it makes a perfect deal on it being a kuso anime. Also, because of its gag humor and parody, you didn't know quite what to expect being the first run-through of a show that is evidently self-aware of itself, and it doesn't care. If you've watched Pop Team Epic back in the day, it was truly absurd and a super freak of even having a brain's IQ worth to assess the anime, even in minute detail, because it is the definition of "fool me once, shame on me". So, how does Season 2 fare against its almost 5-year old prequel season? I would say it's good, but sadly (and obviously) not at the heights of what Season 1 managed to accomplish of its surrealism, absurdity, and non-sequitur natures. And that was Season 1 in a wrap back in early 2018.Īnd here we are again, with Season 2 greenlit right at the tail-end of 2021 after the TV re-broadcast of Season 1 a.k.a Pop Team Epic Repeat, adding in Jun Aoki's Space Neko Company to put more shame to both Takeshobo (the manga company that the source material is published in) and King Records (the anime producer). Not to mention that Sumire Uesaka's OP was a straight BANGER in the absurd midst of thinking that HOW would a show like this get a song that is pure master-lyrical fire. Just a recap, Bkub Okawa's gag parody manga that got translated into the anime, the manga is very rough on the heels, but the anime that was produced by Kamikaze Douga under the helm of its director Jun Aoki (which he would later go on to form his very own studio Space Neko Company), it was unlike ANYTHING that I've seen before with its metaverse of parodies and gag humor, and would easily define as a masterpiece show, just because it's a kuso a.k.a shit-posting anime. Of course, there were other notable shows that only got the attention from the audience that they serve, but if there's one unique show that I constantly would remember being that wacky outcast, it would be Pop Team Epic. As a sidenote, shows like Madhouse's Sora yori mo Tooi Basho a.k.a A Place Further Than The Universe broke the underwhelming season for its CGDCT-like adventure drama which to this day, is still one of the best masterpiece shows that I've watched in my entire life, period. Well, back in Winter 2018, there was a series like it, and based off of mangaka Bkub Okawa's 4-koma manga, that would I would like to ask you a geunine question: Do you still or even remember that Pop Team Epic was a thing back then? For context, anime back then was unlike anime today, served by the beatitudes of its long-standing genres which have come to almost define any seasonal list and stacking heaps upon heaps of mediocrity with some stand-out titles we've come to know in the new decade of the 2020s.

Similarly, the output y(t) computed by lsim is a matrix whose columns represent the signal at each system output. For instance, to simulate a system with four inputs for 201 time steps, provide u as a matrix of four columns and 201 rows, where each row u(i,:) is the vector of input values at the ith time step each column u(:,j) is the signal applied at the jth input. In other words, each column of u is the input signal applied to the corresponding system input. To use lsim, you specify u as a matrix with dimensions Nt-by- Nu, where Nu is the number of system inputs and Nt is the length of t. In a MIMO system, at each time step t, the input u(t) is a vector whose length is the number of inputs.

Thinking it must be coming from the cupboard, he pulls everything off the shelves, but cannot find the source. When he discovers that nobody is there, he returns to bed, only to hear the noise again. Owl hears a squeaky noise as he is going to bed and, thinking it must be somebody at the door, he goes to investigate. There were pictures of Pizzoli's other books on the book jacket, and now my son wants to check them all out at the library. My son also got a big kick of knowing the source of the squeek from the start, and understanding something that Owl didn't. There's just something so amusing about Owl's increasing rage at not being able to find the "squeek", and how completely irrational he gets as the night goes on. I don't even know how to describe what's funny about it. Tonight I got the chance to read it with him, and he was laughing his head off all over again. My husband and I trade off reading bedtime stories with my son, and one night when the boys were reading together I heard my son laughing hysterically about this book. When he picked this one out at the library I worried, based on the cover and simple title, that it would fall into the "babyish and not very exciting" category. My son is 5 and not reading independently yet, which means he is still solidly into picture books, but some of them are becoming a little "babyish" for him. For sorry, but I honestly do not really consider Owl's destructiveness with regard to his roof and walls as presenting a good and positive attitude (and also giving a rather problematic potential message), since in my opinion, Good Night Owl could in a worst case scenario make young children believe that one could and perhaps even should deal with encountered problems (such as Owl's squeaky noise scenario) with anger and by being willfully and openly hostile (and yes, as other reviewers have pointed out, owls generally eat mice, so it is also more than a bit strange that Owl has no issues totally tearing down his house but then seemingly makes friends with the mouse that is the cause of all of this mayhem).Ĭombined with the fact that I have also not found the accompanying illustrations all that aesthetically pleasant, as I do seem to find Greg Pizzoli's pink and pastelly colour scheme not at all to my visual tastes, while I have in no way actively despised Good Night Owl, I also have not found either Pizzoli's text or his artwork personally appealing enough for more than a two star rating. However, I was still willing to swallow and subdue my sense of disbelief, as indeed, Good Night Owl does start out engagingly and humorously enough, with Owl continuously getting out of bed to look for the source of the squeak that is preventing him from settling down (and which readers right from the onset know is a mouse) definitely making me smile, that is UNTIL Owl ends up in a fit of supreme and raw temper basically demolishing his entire house to try to get rid of his noise issue. Well first and foremost, I guess I have to admit that I do find it rather disconcerting and definitely a trifle problematic that author/illustrator Greg Pizzoli has his owl going to sleep at night instead of being up and about (since owls of course are nocturnal and therefore tend to sleep during the day). 8/10/2023 0 Comments Manhattan skyscrapersThe company plans to install carbon capture systems in five more buildings this year. It has computerized motors, fans and pumps, LED lighting and battery storage. The apartment building is trying to reduce energy in other ways, too, said Josh London, senior vice president at Glenwood Management Corp. Pipes lead to spigots outside the building, where a truck loads up with the liquefied CO 2 and takes it to a concrete manufacturer in Brooklyn. Then it's compressed and cooled to minus-10 degrees Fahrenheit (minus-23 Celsius), turning it to liquid. Credit: AP Photo/John MinchilloĬarbon dioxide and other gases flow from the boilers over a special material that separates out the carbon dioxide in a system that occupies two former parking spaces. New York is forcing buildings to clean up, and several are experimenting with capturing the carbon dioxide, cooling it into a liquid and mixing it into concrete where it turns into a mineral. "Boilers like this are installed everywhere, in schools and hospitals around the world," Asparro said.īrian Asparro, chief operating officer of CarbonQuest, points to a delivery truck on a touch screen display outlining the process from which liquid carbon dioxide is produced as a byproduct of a natural gas fired water boiler in the basement of The Grand Tier luxury apartment building, Tuesday, April 18, 2023, in New York. The carbon capture system, Asparro said, is trapping about 60% of the boilers' emissions. The other half are generated at power plants where the building buys electricity. The boilers produce roughly half the building's emissions. In the Manhattan building's basement, two 500-horsepower boilers rumble, burning natural gas and releasing carbon dioxide. It's unclear whether carbon capture will be recognized by New York City as a qualifying emissions reduction the city has not decided. "Carbon capture doesn't actually reduce emissions it seeks to put them somewhere else," said Anthony Rogers-Wright, director of environmental justice at New York Lawyers for the Public Interest. Credit: AP Photo/John MinchilloĬritics say buildings should be switched to electricity instead. New York is forcing buildings to clean up, and several are experimenting with capturing carbon dioxide, cooling it into a liquid and mixing it into concrete where it turns into a mineral. "Time is not on our side, and this type of solution can be installed quickly, cost-effectively and without a major disruption," said Brian Asparro, chief operating officer of CarbonQuest, which built the system.Ī liquid carbon dioxide pipe is labeled in a production room of The Grand Tier luxury apartment building, where the carbon byproduct of a natural gas fired water boiler is repurposed for industrial sale, Tuesday, April 18, 2023, in New York. In this case, the carbon dioxide is sold to a concrete manufacturer in Brooklyn. To comply, some property managers are installing carbon capture systems, which strip out carbon dioxide, direct it into tanks and prepare it for sale to make carbonated beverages or soap. Other cities such as Boston and Denver passed similar laws. So building owners must make dramatic cuts starting next year or face escalating fines under a new law which affects some 50,000 structures-more than half the buildings in the city. In such a vertical city, it's impossible to address climate change without tackling emissions from buildings. The goal is to stop carbon dioxide, a climate-warming gas, from entering the atmosphere. To reduce emissions, the owners have installed twisting pipes and tanks that collect carbon dioxide from the building's massive, gas-fired boilers. Yet the basement has a set of equipment seen almost nowhere else in the world. 8/10/2023 0 Comments Benchmark definition in mathA measured steady-state concentration, for instance, might merely provide information about the ratio k prod/ k deg of production and degradation rates. In such kind of settings, multiple parameter combinations can give rise to the same model response for experimentally investigated conditions. Since the evaluation of distinct experimental conditions is elaborate, the amount of available experimental data for parameter estimation is always limited. In contrast to phenomenological models which describe the empirical relationships in an abstract and simplified manner, the complexity of these so-called mechanistic models is dictated by the complexity of the investigated biological process.Įstimating the parameters of typical models in systems biology requires data that covers a broad set of experimental conditions such as multiple time points, genetic perturbations, and/or treatments. Moreover, biochemical interactions between the considered compounds are translated as rate equations into the model. To this end, molecular compounds such as proteins and spatial compartments such as cells are defined as model components. For simplicity, in the following, this task is sometimes briefly denoted as benchmarking of optimization approaches, although it always refers to the optimization for the fitting of parameters of ODE models which is also termed calibration or model calibration in the literature.Ī major characteristic of the mathematical models applied in systems biology is the intention to mirror the biological process of interest because this facilitates enhanced possibilities of interpretations and understanding. In this article, these aspects are discussed in the context of benchmarking of approaches for optimization-based fitting of mathematical models in systems biology. General guidelines have been provided recently for computational analysis of omics data, multiple alignment of protein sequences, and supervised classification methods as well as for periodic scientific benchmarking and general studies in computational biology. The importance of proper designs for benchmark studies in computational biology has been discussed in several publications. The absence of high-performing software implementations seems to be a major reason why ODE-based modeling is not yet a routinely applied computational approach for analyzing experimental data. Although parameter estimation is a central task of modeling, the lack of reliable computational approaches for fitting is still a bottleneck in systems biology. In addition, the optimization problem needs to be defined in terms of initialization, search space, termination criteria, and hyperparameters that set up and configure the numerical algorithms. Such optimization-based fitting of a model requires the selection of a generic numerical optimization approach as a core algorithm. Both approaches coincide with normally distributed measurement errors. In most cases, parameter estimation is performed by the optimization of a suitable objective function such as minimization of the sum of squared residuals for least squares estimation or maximization of the likelihood for maximum likelihood estimation. Application-specific calibration of the models is therefore required which corresponds to the estimation of these unknown parameters based on experimental data. Hence, they are represented as unknown parameters in mathematical models. Typical parameters in systems biology such as the abundances of compounds or the strengths and velocities of biochemical interactions are typically context-dependent, i.e., they vary between species, tissues, and cell types. In this article, I focus on the optimization-based fitting of these models although many aspects are general and also apply to other modeling types and approaches. In the BioModels Database, currently, 83% of all models which are uniquely assigned to a modeling approach are ODE models. Most frequently, ordinary differential equation models (ODEs) are applied because they enable a non-discretized description of the dynamics of a system and allow for quantitative evaluation of experimental data including statistical interpretations in terms of confidence and significance. Depending on the questions of interest and on the amount of available data, the type of models and the level of detail vary. A broad range of mathematical models is applied in systems biology. 8/10/2023 0 Comments Pogo pin contactsThe springs are usually made of copper alloys or spring steel. Īs common in electrical connectors, manufacturers often apply a gold plating that improves the durability and contact resistance. The plunger and barrel of pogo pins usually use brass or copper as a base material on which a thin layer of nickel is applied. For example, a ball may be added between the two components, or the plunger may have an angled or countersunk tip. Many manufacturers have created their own proprietary variations on this design, most commonly by varying the interface between the plunger and spring. In order to counter this, the plunger usually has a small tilt to ensure a continuous connection. Since a spring-loaded pin needs to have a slight gap between the plunger and barrel so that it can slide easily, momentary disconnections can happen when there is vibration or movement. Thus, a precise normal force, typically around 1 newton, is required to generate this friction. However, high friction is undesirable because it increases stress and wear on the contact springs and housings. In the design of electrical contacts, a certain amount of friction is required to hold a connector in place and retain the contact finish. The shape of the barrel retains the plunger, stopping the spring from pushing it out when the pin is not locked in place. When force is applied to the pin, the spring is compressed and the plunger moves inside the barrel. Spring-loaded pins are precision parts fabricated with a turning and spinning process which does not require a mold, thus allowing the production of smaller quantities at a lower cost.Įxploded diagram showing components of a standard pogo pinĪ basic spring-loaded pin consists of 3 main parts: a plunger, barrel, and spring. Targets may be separate components in the complete connector assembly, or in the case of printed circuit boards, simply a plated area of the board. A pogo target consists of a flat or concave metal surface, which unlike the pins, has no moving parts. Ī complete connection path requires a mating receptacle for the pin to engage, which is termed a target or land. This helical spring makes pogo pins unique, since most other types of pin mechanisms use a cantilever spring or expansion sleeve. The name pogo pin comes from the pin's resemblance to a pogo stick – the integrated helical spring in the pin applies a constant normal force against the back of the mating receptacle or contact plate, counteracting any unwanted movement which might otherwise cause an intermittent connection. They are used for their improved durability over other electrical contacts, and the resilience of their electrical connection to mechanical shock and vibration. Sectional drawing of a pogo pin, showing the plunger, barrel, and springĪ pogo pin or spring-loaded pin is a type of electrical connector mechanism that is used in many modern electronic applications and in the electronics testing industry.

Using a Desoldering Pump – A Push of a Button Does the Trickīefore you begin desoldering joints with your desoldering pump, familiarize yourself with how your pump operates. There are several variations on the market, but they all work on the same principle. Desoldering pumps are little more than spring-loaded plungers that can be activated to vacuum or suck the melted solder away from a solder joint. When you have lots of solder joints to desolder, a desoldering pump can speed up the process. If you routinely desolder parts for reuse, exploring these other options might make your projects easier and quicker. There are other options for desoldering operations that don’t depend on soldering braid or wick. Other Options for Desoldering Electronic Components Prepare the braided shielding just like the stranded wire above. Remove the length of the braided shield from the coaxial cable. If you have a length of coaxial cable laying around, a bit of the braided shielding from the coaxial cable works equally well as desoldering braid or wick. Each time you remove solder, you must trim the end of your homemade desoldering braid to remove that used solder.ĭon’t Forget About Coaxial Cable Shielding
