But some of us are college educated. “They want to portray us as all toothless, redneck tobacco chewers,” Frank Ancona Jr told The Times. In explaining his philosophy, he told the newspaper that his group is nonviolent, supports the separation of races and opposes what he called "equality propaganda." The high-profile shooting brought attention to Frank Ancona Jr., who appeared on national television, to discuss how the race protests following a white police officer's shooting of an unarmed black man had rallied KKK members.Īmong other recent activity, the group under Frank Ancona Jr.'s leadership also passed out pamphlets in several towns in Maine, the Times reported. The New York Times reported that Frank Ancona Jr.'s Ku Klux Klan faction, although not large in number, was successful in distributing pamphlets in the aftermath of the 2014 police shooting of Michael Brown in Ferguson, Missouri, that urged using "lethal force" against protesters. Jinkerson, 26, is facing first-degree murder charges and, also like Malissa Ancona, charges of abandoning a corpse and tampering with evidence. But Malissa Ancona said in court Friday that Jinkerson was not guilty of murder, only the other two crimes.įrank Ancona Jr. told the New York Times in an interview before his death that he had been a member of the Ku Klux Klan for 30 years and had founded the Traditionalist American Knights of the Klan in 2009. In addition, Ancona admitted in court to cleaning the walls of their bedroom and disposing of bloody bedding and dumping Frank Ancona Jr.’s body near Belgrade, Missouri. "I fired both shots that killed my husband,” the Post-Dispatch reported Malissa Ancona told a judge Friday. She said she was "under the influence" when she made her first statements and instead took the blame for the killing. – killed him while he was sleeping with a 9-millimeter handgun after he had asked for a divorce.īut she later changed her tune again in letters from jail, according to the Post-Dispatch. She then said that her son, Paul Jinkerson Jr. – the stepson of Frank Ancona Jr. Originally, Malissa Ancona, of Leadwood, Missouri, reported her husband missing. The Knights has had chapters in Idaho and Pennsylvania as well.įrank Ancona Jr. was killed by gun shot wounds to the head, a coroner determined, after he was found dead on a bank of the Big River near Belgrade, Missouri, about 70 miles southwest of St. The group, based in Park Hills, Missouri, had a presence last year in South Dakota and Florida, according to the Southern Poverty Law Center, which tracks hate groups. Louis Post-Dispatch reported, as well as tampering with evidence and the abandonment of a corpse.Īs part of her plea agreement with state prosecutors, she was sentenced to life in prison.Īncona, who was 51 when he died in February 2017, was imperial wizard of the Traditionalist American Knights of the Ku Klux Klan, which is believed to have only a few dozen members nationwide. Francois County Circuit Court in Farmington, Missouri, to second-degree murder in the death of Frank Ancona Jr., the St. Malissa Ancona, 46, pleaded guilty in St. Now, she says her son didn't help commit the homicide.

every 10seconds: the values of soil humidity, air humidity and temperature, and the output states of lights, vents, and part of the humidifier(the part of turning it on, don't ask me why) The setup portion of the code initializes the 16x02 LCD(screen), DHT11(air humidity and temperature sensor), the interrupts for the rotary encoder, the EEPROM(memory for values) and other stuff. Take a stopwatch, do some testing with your water pump, and remember that 1 second = 1000 miliseconds. It is named msPERdL(miliseconds/decilitre) and it tells the programme how many miliseconds it takes for the water pump to pump one decilitre. The schematic and even more so the code might evolve a bit, so don't be a stranger and check from time to time, even if you happen to build it and it works fine.įirst I will explain the variable most likely in the need of some tweeking. To do this instructable you must have some knowledge of electronics and know how to load code to an Arduino and how to power an Arduino. It can, like most arduino projects, be expanded to great heights. Going as cheap as I can and making a sistem independent of a PC were my guides through this project. The mentioned instructable looks great and a bit long, so in the spirit of diversity I will make this one as plug-and-play as I can. I was already too hooked on making it my way. The instructable is for one connection to each a water pump, light, vent, air humidifier as outputs and a soil humidity sensor, air humidity and temperature sensor, and of course the user, as inputs. It's a plan for a grow box with the focus being on the lcd(output)/rotary encoder(input) system. Home grown food, medicine, mushrooms, some incense maybe? You can try this instructable for starters.

Her father's film directing took the family to Africa, India, Spain, Switzerland, England, and the United States. Danielewski, lived in six different countries before she turned eight. Danielewski and his wife Priscilla Decatur Machold, Poe and her brother, novelist Mark Z. Early life īorn in New York City and daughter of Polish film director Tad Z. Poe joined others singing in the music video that included a video clip of John Lennon that spearheads a global campaign by UNICEF to celebrate the 25th anniversary of the Convention on the Rights of the Child. The campaign launched a world version of John Lennon's classic song "Imagine" featuring dozens of musical artists from around the world. In September 2014, Poe received the title of UNICEF Goodwill Ambassador due to her invitation by Yoko Ono to participate in a UNICEF campaign and her donated performance. In 2004, she co-founded the digital innovations agency Signature Creative Inc with John Gheur. Atlantic Records' Senior Vice President of New Media, Nikki Sleight, referred to Poe's online power and one-on-one communication with thousands attending her concerts as "unheard of and pretty phenomenal" in Sleight's 1997 interview with Web Magazine. Her web site, and the fan sites that supported her early in her career, predated modern social networking platforms and were among the first of their kind. Noteworthy was Poe's early involvement with her online community of fans. Poe spent six years with Atlantic Records and is currently on her own label, Repoezessed Music Records. Some of her early charting singles included " Angry Johnny", " Trigger Happy Jack", " Hello", and " Hey Pretty." Videos for these singles had heavy rotation on MTV. Poe first hit the modern rock charts in 1995. Many of Poe's songs have been featured in films and on television. Poe's musical style is a blend of rock, jazz, electronica, folk, and hip hop elements combined with intimate lyrical compositions. Poe (born Anne Decatur Danielewski March 23, 1968) is an American singer, songwriter, and record producer. Just click it again to return to puzzle number form.

The constructor with lots of parameters has its downside: not all the parameters are needed at all times. While this approach indeed eliminates the need for subclasses, it creates another problem. You can create a giant constructor right in the base House class with all possible parameters that control the house object. There’s another approach that doesn’t involve breeding subclasses. Any new parameter, such as the porch style, will require growing this hierarchy even more. But eventually you’ll end up with a considerable number of subclasses. The simplest solution is to extend the base House class and create a set of subclasses to cover all combinations of the parameters. But what if you want a bigger, brighter house, with a backyard and other goodies (like a heating system, plumbing, and electrical wiring)? To build a simple house, you need to construct four walls and a floor, install a door, fit a pair of windows, and build a roof. You might make the program too complex by creating a subclass for every possible configuration of an object.įor example, let’s think about how to create a House object. Or even worse: scattered all over the client code. Such initialization code is usually buried inside a monstrous constructor with lots of parameters.

It helps developers know the possible inputs and scenarios that the project should process and perform.įurthermore, you will find out the needed processes and connect them to the other UML Diagrams. The use case diagram is one of the methods that contribute to the Online Shopping Cart design and development. Then place the figured use cases included in doing the process.Īfter that, you will trace the association of the use cases to know the interactions between the user/s and the system.įinally, put the container in the plotted diagram to separate the objects’ (users and system) scope. You need to place first the users involved. You will base the flow of use cases on the evaluated information from the users. To plot the diagram you will need the users, use cases, container (scope), and their indicators (association). But, only have the useful processes and circumstances related to the shopping cart. The gathered information from the users needs to be evaluated to know the general use cases.įrom the general use cases, you will see the sub-cases that are included. You may ask the users about the typical activities done in online shopping. They will be the ones to use your project. The next step is to determine your targeted users. Step 1: Familiarize Use Case Diagram Symbolsįor beginners in the field of designing the diagram, you need first to familiarize the symbols to be used.Here’s the complete guide on how to draw a use case diagram for online shopping cart. It includes the procedures from the viewpoint of users. To help the developers and enterprises in developing the system is the importance of the UML use case diagram. Therefore, this diagram depicts the high-level functionality of a system including how the user interacts with it. This also provides a clear picture of the user and system relationships. Moreover, the diagram assists you in defining and organizing project requirements. It encapsulates the project’s functionality by incorporating use cases, actors, and their interactions. The use case diagram in software engineering shows the sample adaptive behavior of the shopping software.

Use Case Diagram for Online Shopping Cart Read our Anker Nebula Cosmos Laser 4K review The Anker Nebula Cosmos Laser 4K has plenty of competition, but if you want a projector that will regularly work in a lot of different places around your home rather than outside it, there are few options that will do it as well and as easily as this one. With built-in speakers and an included streaming stick that stashes away behind a cover, it even has the skill to power the entire entertainment setup for whatever space you bring it into. Check out the Anker Nebula Solar Portable above if you're looking for on-board battery instead. It’s easy to bring from place to place, but you’ll still need AC power to use it." Bear that in mind if you're looking for a projector to take outdoors or far from home. In the review we wrote: "Without battery power, the Anker Nebula Cosmos Laser 4K isn’t exactly portable. However, there's a big problem when it comes to the Cosmos Laser 4K's portability: there's no on-board battery. But its form factor at 26.4 x 22 x 15.5 cm and weighing 4.8kg means we had no trouble packing it up and carrying it from room to room when we were reviewing it. It's more than capable enough of being your go-to projector and staying put in your living room - it looks great, too. It’s packing in some considerable brightness, peaking out at 2,400 Lumens, which we found to be sufficiently bright for a semi-light-controlled environment during our testing, and its laser lamp makes for a high-quality image. The Anker Nebula Cosmos Laser 4K is not your average compact projector. Read our Anker Nebula Solar Portable projector review But if you want a bright and impressive picture, you'll need to upgrade to one of Anker's more high-end models, like the Anker Nebula Cosmos Laser 4K below. If you're looking for a decent projector, it's a good choice. The listed 400 lumens brightness means the Nebula Solar Portable will struggle to remain visible in bright environments, while dark scenes are difficult even in ideal viewing conditions. While the picture quality is pretty adequate for the price and form factor, during our testing, we were disappointed to find the projector was a letdown on the brightness front. The Bluetooth speaker functionality is a great addition to the Solar Portable’s feature set, effectively delivering two devices in one: a Bluetooth speaker and a projector. However, its USB-C power port means you should also be able to link up a portable power bank for multiple uses. We found the battery will last about three hours, which is decent for such a small, portable projector and should be good for getting in a film when you’re not close to a plug socket. But measuring 19.2 x 19.22 x 5.45cm and weighing only 2.38kg, it’s small enough to fit easily into a drawer, backpack, or tote bag for taking outside. It sports a sleek design and will look great on a shelf in your living room between uses. The Anker Nebula Solar Portable is a compact and stylish mini projector that we enjoyed testing because it delivers in almost every area at an affordable price. In our review of the Samsung The Freestyle projector, we wrote: "Compact, portable and with a built-in suite of apps, The Freestyle is a projector that offers everything you need in one place." All you need to do is provide a blank surface to project onto. It isn't the cheapest option on this list - look at the Anker Nebula Solar Portable below for a budget alternative - but it's the most polished and covers all of the bases. The Freestyle is easily our pick for the best portable projector you can buy now. It weighs just 0.8kg, and at 95.2 x 171.4 x 95.2mm, it's roughly the size of dog food, so you can easily pick it up and throw it in your backpack.Īdd to this its impressive (if somewhat fussy) auto-leveling functionality, excellent Full HD picture quality, and surprisingly loud built-in 360° speaker. Speaking of taking it with you, we were surprised by just how portable this projector is during our testing. It's like a Samsung TV OS that you can take with you. This Samsung projector keeps its approachability by offering built-in smart features and streaming apps. Starting with its streamlined setup process, which we found a breeze to use as it had us up and running in moments. Everything about Samsung's The Freestyle projector is geared towards ease of use.

Sweet way to Send Christmas Cookies on Holiday This Year in SurinameĬhristmas holiday season is soon going to knock the doors. It can also be written in terms of a surface integral of a scalar field, where n^ is the normal vector to the surface. We have a vector field u → defined on the surface, the surface integral of the vector field is defined as: ∫ S u → ∙ dS → If the scalar field f(r) = 1, then the surface integral just gives us the area of the surface. We compute this integral by parameterizing the surface, by actually parameterizing r. The surface integral of the scalar field will be obtained by a Riemann sum, where we break the surface into small surface elements dS. Then multiply each element dS by the average value of the scalar field f, and finally we sum over all of those surface elements. We have some surface in three-dimensions. The surface itself is a two-dimensional object. We have a scalar field f defined on the surface. The work is actually line integral of the force along the curve, it is done by the force on the mass results in the change in the kinetic energy of the mass. Work in a physicist definition is the energy transferred to an object by a force. Usually we do the integral by parameterizing the curve. It’s basically saying that you have to take the component of u → along the curve to do the line integral: ∫ c u → ∙ dr →īut this actually can be written in terms of a line integral of a scalar field, where t^ is the tangent unit vector: ∫ c (u → ∙ t^) ds At the same time we have an element of the curve dr →, pointing and along the direction of the curve. On this curve, we have a well-defined vector field u →. Most of the physical problems that we define in terms of line integrals are actually line integrals of a vector field. Curve is parameterized x = x(t), y = y(t).There are 2 method of solving this integral: Then the integral is Riemann sum: ∫ c f(r) ds To do a line integral, we break the curve into small pieces ds, you have a small element of length ds and a value of f on that element, we multiply them together, and then we sum over all of the elements on the curve C. In Figure 12.9.5 you can select between five different vector fields.We have a curve C in the x-y plane, we can represent a point on this curve then by a vector r. In this activity, you will compare the net flow of different vector fields through our sample surface. Thus, the net flow of the vector field through this surface is positive. If we define a positive flow through our surface as being consistent with the yellow vector in Figure 12.9.4, then there is more positive flow (in terms of both magnitude and area) than negative flow through the surface. If we have a parametrization of the surface, then the vector \(\vr_s \times \vr_t\) varies smoothly across our surface and gives a consistent way to describe which direction we choose as “through” the surface. In other words, we will need to pay attention to the direction in which these vectors move through our surface and not just the magnitude of the green vectors. Notice that some of the green vectors are moving through the surface in a direction opposite of others. In order to measure the amount of the vector field that moves through the plotted section of the surface, we must find the accumulation of the lengths of the green vectors in Figure 12.9.4. The decomposition of three-dimensional vector field evaluated along a surface into normal and tangent components The component that is tangent to the surface is plotted in purple. One component, plotted in green, is orthogonal to the surface. In the next figure, we have split the vector field along our surface into two components. Any portion of our vector field that flows along (or tangent) to the surface will not contribute to the amount that goes through the surface. The central question we would like to consider is “How can we measure the amount of a three dimensional vector field that flows through a particular section of a curved surface?”, so we only need to consider the amount of the vector field that flows through the surface. A three-dimensional vector field evaluated along a surface So instead, we will look at Figure 12.9.3. We don't care about the vector field away from the surface, so we really would like to just examine what the output vectors for the \((x,y,z)\) points on our surface. A three-dimensional vector field and a surface We are interested in measuring the flow of the fluid through the shaded surface portion. There is also a vector field, perhaps representing some fluid that is flowing. We have a piece of a surface, shown by using shading. In Figure 12.9.2, we illustrate the situation that we wish to study in the remainder of this section. \newcommand\) Subsection 12.9.1 The Idea of the Flux of a Vector Field through a Surface |
