![]() Here, we plot the coefficient of the pitching moment (C m) as a function of the angle of attack. This last polar is more concerned with the general stability of the airfoil. The lift over drag ratio is a common way to determine the optimum flight scenario for your UAV because it provides the highest efficiency in terms of lift and drag.įigure 4: Coefficient of lift for various airfoils in relation to the coefficient of drag. If you draw a straight line from the origin upward, then pivot it until it touches the polar, the slope is the airfoil’s theoretical maximum L/D. This is useful mostly in helping us to determine the maximum lift over drag ratio, or L/D. This one shows the coefficient of lift (C l) as a function of the coefficient of drag (C d). For example, lift will be lost more gradually on the airfoil represented by the green line than the light blue line, which drops sharply and will lose lift very quickly after beginning to stall at C l max. A gentler downward curve represents an airfoil with a more forgiving stall development. Another interesting feature is the shape of the peak. Here, the airfoil represented by the dark blue line obviously has the highest C l max (about 1.6). This is advantageous because it allows the UAV to take off with smaller lifting surfaces and increases overall aerodynamic efficiency. Some airfoils have a higher peak than others, signifying a higher maximum C l. This is represented on the polar by a peak and eventual downward curve (see Figure 3).įigure 3: Coefficient of lift for various airfoils at different angles of attack. At around 10-12 degrees, the airfoil begins to stall, meaning that large amounts of drag are beginning to occur and lift is being lost. As you increase the angle of the airfoil relative to free flow, the coefficient of lift will increase with a slope of about 2π (C l/α in radians). There is at first a linear relationship between the C l and angle of attack. The first thing you should notice is the general shape of the polar. Let’s look at the polar that plots the coefficient of lift as a function of angle of attack (α) for various airfoils. There are a few key characteristics you are looking for that will be shown on your lift and drag polars. Lift is explained in further detail in fluid mechanics. This is different than lift itself, which is simply the force acting on an aircraft perpendicular to the free stream. The coefficient of lift is a nondimensional parameter that helps us to understand the general lifting capabilities of an airfoil (see equation below). ![]() Keep in mind that with airfoils we are calculating a theoretical coefficient of lift (C l). These and a few other metrics will indicate the airfoil’s performance. One of the most important considerations when selecting an airfoil is the lift and drag characteristics. Generally, a more cambered airfoil will provide more lift with decreased aerodynamic stability. Camber is the relative distance between the chord line and camber line, measured in chords. The camber line lies exactly (vertically) between the upper and lower surfaces of the airfoil at any point. Most small UAV’s have a thickness-to-chord ratio of about 8-14%. The last two digits give the maximum thickness, which is 12% of the chord length here. In this case, there is a 4% maximum camber at 40% of the chord length from the leading edge. The first two digits describe the magnitude and placement of the camber, respectively. Let’s use the NACA 4412 airfoil as an example. Each digit describes a different parameter of the airfoil. The NACA four-digit series provides a convenient way to demonstrate some additional airfoil parameters. If you were to draw a straight line from edge to edge, this would be called the chord line and its length is the chord length (or just “chord”). The front (or forward most part) is called the leading edge, while the back (or aft most part) is called the trailing edge. This provides large amounts of lift with minimal drag. ![]() ![]() As you can see below, an airfoil typically has a thin, long profile. To start, let’s discuss the different parts of an airfoil. These and other important concepts will be discussed. Relevant requirements may relate to stability, lift and drag characteristics, and manufacturability. As such, care should be taken to choose an airfoil that properly meets the performance requirements for your mission. The airfoil will play a large role in determining its aerodynamic performance characteristics and capabilities. ![]() Airfoil selection is one of the earliest and most important decisions made when desiging your UAV. ![]()

![]() ![]() Announcing the existence of your game.In an ideal world, we would all have the time and the money to create three different trailers for three key occasions: Decide what you want to achieve, which can depend on a lot of things. This one is very important! Settle on one key message you want to convey. Your friends will probably be very critical (the honest ones at least), while your mom will probably say something like ”Oh that’s yeah very nice, sweety.” 7. Be prepared to receive negative or non-usable feedback too. You might get some feedback that makes you want to rethink some things or reorder some scenes. Us indie developers may have to rely on our trusted relatives and friend circle for this, but still, it’s always best to get some outside opinion from people that haven’t been involved in the creation process in any way. ![]() How interesting was the trailer? Did they want to keep watching? Did they understand the story? Big production houses do this too, only they can afford to test their trailers with focus groups. Show this to your team but also to your family and friends who have never played your game and ask them what they think. Make a mock-up/first draft that you can test. Here’s a couple of shots from the storyboard I’ve made as an example (note: the yellow thing is a robot puppy from our game, not a deer suffering from jaundice).Ħ. Make sure to show something very eye-catching that peaks interest as early as possible in the video! Keep in mind: you don’t have to be an artist to draw a storyboard. You have 2-3 seconds to hook the audience before they lose interest and scurry to another YouTube video. You may want to check out the videos of trailer-wizard Derek Lieu who has great advice on this! The first shots are crucial. Even if you’re only making a gameplay trailer without a plotline you should have a story arc that draws viewers in and makes them keep watching your trailer. This is very important as you will have to fit your scenes to be in sync with the music for the best possible result. Go through your list and try to imagine how each of your items would look while that song is playing. These are the things about your game that attract players and set your game apart from other games. These should also include your game’s hooks and USPs (Unique Selling Points). Make a list of the coolest looking things you want to show off in your game. ![]() ![]() ![]() ![]() As a last resort, they attempted an emergency landing in an open field about 300 yd (270 m) from where the plane eventually went down. Upon realizing that the plane had insufficient fuel, the pilots attempted to navigate to McComb Airport, about 10 mi (16 km) northeast of the eventual crash site in Amite County, Mississippi, but soon realized that the plane would not make it. The plane ran out of fuel near the end of the flight. The following day they boarded a Convair CV-240 airplane to take them to Baton Rouge, Louisiana, where they were to perform at Louisiana State University. On October 19, 1977, two days after releasing their album Street Survivors, Lynyrd Skynyrd performed at the Greenville Memorial Auditorium in Greenville, South Carolina. The tragedy abruptly halted Lynyrd Skynyrd's career until Van Zant's brother Johnny reformed the band ten years later. Lynyrd Skynyrd lead vocalist and founding member Ronnie Van Zant, guitarist and vocalist Steve Gaines, backing vocalist Cassie Gaines (Steve's older sister), assistant road manager Dean Kilpatrick, Captain Walter McCreary and First Officer William John Gray all died as a result of the crash, while twenty others survived.

The solution to these issues is usually to create a symbolic link (symlink) from the plugin's expected write location to a location in the writable filesystem ( /sites/default/files for Drupal, wp-content/uploads for WordPress). Refer to documentation on Using the Pantheon WebOps Workflow for more information on how Pantheon differentiates "code" from "files". This can result in runtime errors when the software can't write to locations in the codebase in Test and Live environments. While this is usually true of standard LAMP/LEMP stack server configuration, Pantheon and other specialized platforms do not.

Microsociologists would instead focus on such things as why individual robbers decide to commit a robbery and how they select their targets. Macrosociologists would discuss such things as why robbery rates are higher in poorer communities and whether these rates change with changes in the national economy. ![]() The different but complementary nature of these two approaches can be seen in the case of armed robbery. These sociologists examine how and why individuals interact and interpret the meanings of their interaction. Figure 1.9: Microsociologists examine the interaction of small groups of people, such as the two women conversing here. Their views taken together offer a fuller understanding of the phenomena than either approach can offer alone. Often macro- and microsociologists look at the same phenomena but do so in different ways.

Google Earth lets you take a virtual trip to anywhere in the world, with tons of photos, information, and other types of interactive displays you can explore. Google Earth, in contrast, has been a program that you download and save on your computer, though now it does have a web browser plugin functionality. The main difference between the two is that Google Maps is accessed through a Web browser and an Internet connection. This is largely due to the addition of new features to Google Maps, such as support for 3D Imagery and other features that used to only be available in Google Earth. Google Earth and Google Maps used to be very different products, but over the past few years they’ve become much more similar. ![]() ![]() ![]() The DSM -5 identifies the following conditions as comorbid: Other personality disorders, specifically, schizotypal, schizoid, narcissistic, avoidant, and borderline personality disorder. The DSM-5 indicates that a family history of Schizophrenia, or persecutory type delusional disorder are risk factors for Paranoid Personality Disorder (American Psychiatric Association, 2013). (American Psychiatric Association, 2013). PrevalenceĪccording to the DSM-5, the prevalence of Paranoid Personality Disorder is 2.3 % to 4.4 % of the US population, and is more frequently diagnosed in males. This could be a contributing factor in the development of paranoid personality. A child who exhibits abnormal behaviors and who is rejected by peers, may learn not to trust, and may become suspicious of others motives. This is an interesting note, in that it raises questions of premorbid causality. Children may act strangely, resulting in teasing (American Psychiatric Association, 2013). The DSM-5 notes that Paranoid Personality Disorder features may be apparent in childhood and adolescence. Will be jealous and suspicious without cause that intimate partners are being unfaithful.Ĭriterion B is that the above symptoms will not be during a psychotic episode in schizophrenia, bipolar disorder, or depressive disorder with psychotic features,Ī qualifier is that if the diagnostic criteria for PPD is met prior to the onset of Schizophrenia, it should be noted Paranoid Personality Disorder was premorbid (American Psychiatric Association, 2013). In the absence of objective evidence, believe their reputation or character are being assailed by others, and will retaliate in some manner andħ. The seven sub features of criterion A are:ġ.The person with PPD will believe others are using, lying to, or harming them, without apparent evidence thereof.Ģ.They will have doubts about the loyalty and trustworthiness of others,ģ.,They will not confide in others due to the belief that their confidence will be betrayed.Ĥ.They will interpret ambiguous or benign remarks as hurtful or threatening, andĦ. Symptoms of Paranoid Personality DisorderĪccording to the DSM-5, there are two primary diagnostic criterion for Paranoid Personality Disorder of which criterion A has seven sub features, four of which must be present to warrant a diagnosis of PPD:Ĭriterion A is: Global mistrust and suspicion of others motives which commences in adulthood. PPD is also not regarded as a result of trauma, as the perception of being unsafe in the world which is typical of persons with PTSD (Post -traumatic Stress Disorder) is of a different quality and etiology. ![]() Paranoid Personality Disorder is not amenable to antipsychotic medications as there are not typically gross deficits in reality testing, and the paranoid thought content and beliefs are typically-non bizarre. Persons with Paranoid Personality Disorder may develop brief psychotic reactions under stress, but by definition, a brief psychotic episode is discrete and does not endure. ![]() Paranoid Personality Disorder is a non-psychotic disorder, in that it is a discrete diagnosis involving one's dysfunctional and maladaptive personality characteristics, rather then a thought or mood disorder. They will be highly critical of others, but will respond to criticism of themselves with hostility or defensiveness. Generally they have a difficult time getting along with others People with Paranoid Personality Disorder tend to do poorly with group activities and collaborative projects. They may appear guarded and secretive, very rational, logical, and unemotional, but at times will be sarcastic, hostile, and rigid. They tend to be aloof, cold, distant, argumentative, and frequently complain. Persons with PPD are hypervigilant to physical, verbal or social attacks, and do not trust others, and therefore tend to have few if any close or intimate associates. Paranoid Personality Disorder is referred to as a Cluster A personality disorder, which involve “ odd or eccentric “ behavior patterns (Esterberg, Goulding, & Walker, 2010). ![]() PPD (Paranoid Personality Disorder) is a DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, fifth edition), diagnosis assigned to individuals who have a pervasive, persistent, and enduring mistrust of others, and a profoundly cynical view of others and the world (American Psychiatric Association, 2013).
