On the other hand, since $A,B$ being nonsingular gives us that $AB$ is nonsingular, then we also have that 2) if $AB$ is singular, then at least one of $A$ and $B$ must be singular as well. van der pol circuit SINGULAR PERTURBATIONS FOR THE FORCED VAN. Notice, by the way, that we also showed that 1) $AB$ is singular if $B$ is the one assumed singular. The Matrix form of the Van der Pol equation - MathOverflow. But now we have that $(AB)a=A(Ba)=Ab=0$, and we conclude (again) that $AB$ is singular. Now, use that $B$ is nonsingular to find $a$ such that $Ba=b$. If, on the other hand, $B$ is nonsingular, use that $A$ is singular to find $b\ne 0$ such that $Ab=0$. This technique was reinvented several times. ) This strategy is particularly advantageous if A is diagonal and D CA 1 B (the Schur complement of A) is a small matrix, since they are the only matrices requiring inversion. Furthermore, A and D CA 1 B must be nonsingular. (A must be square, so that it can be inverted. If $B$ is also singular, then for some $x\ne 0$ we have $Bx=0$, but then $(AB)x=A(Bx)=A0=0$, and we conclude that $AB$ is also singular. 1) where A, B, C and D are matrix sub-blocks of arbitrary size. That $C$ is nonsingular, on the other hand, gives us in particular that the column space of $C$ has full rank, that is, for any vector $b$ there is a vector $a$ such that $Ca=b$. In electrical engineering, modified nodal analysis or MNA is an extension of nodal analysis which not only determines the circuits node voltages but also. One approach is this: That a matrix $C$ is singular gives us in particular that its null space is non-trivial, that is, for some vector $x\ne0$ we have $Cx=0$.

You can also choose cotton or polyester curtains. They are classy, drape well, and look sophisticated, but most importantly, they keep the light out. Velvet curtains are absolutely ideal for creating a truly theater-like experience. But if, in addition to the benefits of total darkness, you want a fashion accessory, blackout curtains are a perfect choice. There are several window-covering solutions on the market, such as blinds and shades. Blocking the windows will help you create the right atmosphere for your movie time. We are not interested in installing windows, but they come in handy to ventilate the room if they are already there. Lighting is obviously crucial in a modern media room. Sarte Studio Design Idea Modern media room lighting It’s true that leather is easier to clean, and lasts longer, but it’s up to you. However, some people prefer using leather because fabrics are more prone to take on ugly smells. You can also use more subdued colors or lighter tones in furniture and textiles to highlight the decor.įabrics come in lots of colors and textures. Choosing dark gray walls, for example, and the carpet and sofas in matching colors create an inviting atmosphere for your modern media room. Colors such as gray, blue, brown, burgundy, and purple are good alternatives. Main Frameĭark colors are the best for walls and floors. Ideally, this space should not have direct communication with the outside so that the surround sound has better resonance and sunlight does not interfere with the film quality. To install your modern media room, first, you must pick a room, like an attic, the basement, or the living room. Having a media room to enjoy our favorite movies, series, concerts, or even play video games is becoming increasingly common. Home theaters and media rooms are no longer luxury items only for the rich and famous. You will find some extraordinary modern media room ideas to design the entertainment space of your dreams. So, what are the basics of decorating a modern media room?ĭo not miss any detail of this article. In fact, you may also want to use it for entertaining, gaming, or simply listening to music. Still, not everyone wants to have a media room exclusively for watching movies. When we think of a media room, we immediately think of a large screen, surround sound, and comfortable seating. The pandemic has forced us to change our lifestyle, so other options are opening up in the world of interior design, as is the case of in-home movie theaters and media rooms. Usually, when we talk about interior design, we always refer to kitchens, living rooms, dining rooms, bathrooms, and bedrooms. This room is upstairs, so we have woodent subfloors. This wouldn’t work for us downstairs because we have a concrete slab under our carpet.How to decorate the modern media room of your dreams And you know what?! It worked!! We removed the screws to see if there was any damage and because of how close the carpet fibers are you can’t even see the hole that was in the floorboard! That’s our hack! Screw it down! (Disclaimer: make sure you’re screwing into wooden sub-flooring. A while back, after trying every rug tape that ever lived, we decided to try screwing the rug into the floorboard. Especially when you have heavy furniture on top of it. The Rug we chose for this space is a large one-9×12’-and we have a HACK for you! Have you ever tried laying a rug on top of carpet? It honestly doesn’t work. I think it could also look great in a bedroom above a bed too! Did you know that Home Depot had all of this cool home décor to choose from? That bear honestly completes the space-and could really work in so many spaces. We paired those with this Wall Art (Bear Canvas) that is a whopping 54” x 54” wall hanging. The soft amber glow of the light really helps set that ambiance that we were looking for in a theater room. For the side wall, we really wanted warm, moody, modern lighting and these iron Home Decorator’s wall sconces fit that description perfectly. The CarterCopter uses X-Plane for flight training and research. Since designing an aircraft is relatively simple and the flight model can help predict performance of real-world aircraft, several aircraft companies use X-Plane in their design process. This has created an active community of users who use the simulator for a variety of purposes. Users are encouraged to design their own aircraft, and design software titled Plane Maker and Airfoil Maker are included with the program. X-Plane can model fairly complex aircraft designs, including helicopters, rockets, rotorcraft, and tilt-rotor craft.Īn Airbus A340 at Heathrow Airport, an example of one of the many 3rd party aircraft/scenery packages available for X-Plane This approach allows users to design aircraft quickly and easily, as the simulator engine immediately illustrates how an aircraft with a given design might perform in the real world. When this process is applied to each component, the simulated aircraft will fly similarly to its real-life counterpart. After that, the lift and drag of each section are calculated, and the resulting effect is applied to the whole aircraft. wing) may be made up of many sections (1 to 4 is typical), and each section is further divided into as many as 10 separate subsections. With blade element theory, a surface (e.g. Blade-element theory and other computational aerodynamic models are often used to compute aerodynamic forces in real-time or pre-compute aerodynamic forces of a new design for use in a simulator employing lookup tables. These simulators sufficiently simulate the flight characteristics of the aircraft, specifically those with known aerodynamic data, but are not useful in design work, and do not predict the performance of aircraft when the actual figures are not available.īlade element theory improves on this type of simulation, by modeling the forces and moments on an aircraft and individually evaluating the parts that constitute it. Traditionally, flight simulators emulate the real-world performance of an aircraft by using empirical data in predefined lookup tables to determine aerodynamic forces such as lift or drag, which vary with differing flight conditions. X-Plane differentiates itself from other simulators by implementing an aerodynamic model called blade element theory. Screenshot of X-Plane 12.00: Van's RV-10 at Appleton International Airport out of the box New aircraft such as the Airbus A330, Cessna Citation X, F-14, PA-18 SuperCub with tundra tires and Cirrus SR22 are included. Along with the flight model, automatic terrain generation (autogen), and water improvements, it features a new weather engine featuring volumetric clouds and windscreen rain effects. It was released as an early access version on September 6, 2022. On September 25, 2021, X-Plane 12 was announced at Flight Sim Expo 2021. Although initially available for free, only five initial locations are available without the purchase of a monthly subscription. On December 9, 2019, X-Plane Mobile Global, a major update for the mobile port, was released. In September 2020, Update 11.50 introduced support for Vulkan and Metal. The official release of X-Plane 11 took place on March 30, 2017. The company released a second public beta on December 6, 2016, which addressed some significant issues. In November 2016, Laminar Research released the public beta of their latest simulator version, X-Plane 11, to the general public. This is further enhanced by the X-Plane forums, where users can share aircraft, scenery, plugins, and the Scenery Gateway website, which allows users to share airports with other users, which can be eventually integrated into the base product. X-Plane also has a plugin architecture that allows users to create their modules, extending the software's functionality by letting users create their worlds or replicas of places on Earth. X-Plane is pre-packaged with several commercial and military aircraft and global scenery, which covers most of the Earth. A mobile version has been available for Android, iOS, and webOS since 2009 as well. In addition, Laminar Research also distributes FAA-certified versions for professional use. X-Plane is the only flight simulator suitable for Windows and macOS, with commercial desktop versions sold for macOS, Windows, and Linux. X-Plane is a flight simulation engine series developed and published by Laminar Research in 1995. The original surname of the family was Scozzese (meaning Scot/Scottish in Italian), later changed to Scorsese because of a transcription error. Both of them were of Italian descent: his paternal grandparents, Francesco Paolo and Teresa Scozzese, emigrated from Polizzi Generosa, while his maternal grandparents, Martino and Domenica Cappa, emigrated from Ciminna, both in the province of Palermo, Sicily. Charles was a clothes presser and an actor while Catherine was a seamstress and an actress. Both of Scorsese's parents, Charles Scorsese and Catherine Scorsese (born Cappa), worked in New York's Garment District. His family moved to Little Italy in Manhattan before he started school. Martin Scorsese was born on November 17, 1942, in the Flushing area of New York City's Queens borough. įrom left: Salvo Cuccia, Scorsese and Vittorio De Seta at the 2005 Tribeca Film Festival An advocate for film preservation and restoration, he founded three nonprofit organizations: The Film Foundation in 1990, the World Cinema Foundation in 2007, and the African Film Heritage Project in 2017. He is also known for several rock music documentaries including The Last Waltz (1978), No Direction Home (2005), Shine a Light (2008), and George Harrison: Living in the Material World (2011). In addition to film, Scorsese has directed episodes for some television series including the HBO series Boardwalk Empire (2011–2015), and Vinyl (2016), as well as the HBO documentary Public Speaking (2010), and the Netflix docu-series Pretend It's a City (2021). His other films include After Hours (1985), The Last Temptation of Christ (1988), The Age of Innocence (1993), Kundun (1997), Hugo (2011), and Silence (2016).

These films include Gangs of New York (2002), The Aviator (2004), The Departed (2006), Shutter Island (2010) and The Wolf of Wall Street (2013). In the following decades, Scorsese garnered critical acclaim and box office success with a series of collaborations with Leonardo DiCaprio. Scorsese won the Palme d'Or at Cannes with his 1976 psychological thriller Taxi Driver, which starred Robert De Niro, who became associated with Scorsese through eight more films including New York, New York (1977), Raging Bull (1980) The King of Comedy (1982), Goodfellas (1990), and Casino (1995). His 1973 crime film Mean Streets was a blueprint for his filmmaking styles. His trademark styles include extensive use of slow motion and freeze frames, graphic depictions of extreme violence, and liberal use of profanity. In the 1970s and 1980s decades, Scorsese's films, much influenced by his Italian-American background and upbringing in New York City, center on macho-posturing men and explore crime, machismo, nihilism, and Catholic concepts of guilt and redemption. His directorial debut, Who's That Knocking at My Door (1967), was accepted into the Chicago Film Festival. Scorsese received an MA from New York University's Steinhardt School of Culture, Education, and Human Development in 1968. Five of his films have been inducted into the National Film Registry by the Library of Congress as "culturally, historically or aesthetically significant". DeMille Award in 2010, and the BAFTA Fellowship in 2012. He has been honored with the AFI Life Achievement Award in 1997, the Film Society of Lincoln Center tribute in 1998, the Kennedy Center Honor in 2007, the Cecil B. He is the recipient of many major accolades, including an Academy Award, four BAFTA Awards, three Emmy Awards, a Grammy Award, three Golden Globe Awards, and two Directors Guild of America Awards.

Pink, bestselling author of Drive "A friendly, approachable, and compulsively readable narrative that will not only make you want to start your own happiness project but will also make you want to invite Rubin out for a cup of coffee." San Diego Union-Tribune "For those who generally loathe the self-help genre, Rubin's book is a breath of peppermint-scented air. This is the rare book that will make you both smile and think-often on the same page." Daniel H. Every mom will find gems in this book." Praise for The Happiness Project "Once you've read Gretchen Rubin's tale of a year spent searching for satisfaction, you'll want to start your own happiness project and get your friends and family to join you. But the advice, added together, is a big ball of happy. Rubin's warm, doable and sweet tips seem small when you check them off one by one. It's her latest release called Happier at Home. A new book just came out that's just as good as Gretchen Rubin's The Happiness Project. With her signature blend of memoir, science, philosophy, and experimentation, Rubin's passion for her subject jumps off the page, and reading just a few chapters of this book will inspire readers to find more happiness in their own lives. Each month, Rubin tackles a different theme as she experiments with concrete, manageable resolutions-and this time, she coaxes her family to try some resolutions, as well. How can she control the cubicle in her pocket? How might she spotlight her family's treasured possessions? And it really was time to replace that dud toaster. Here she goes deeper on factors that matter for home, such as possessions, marriage, time, and parenthood. In The Happiness Project, she worked out general theories of happiness. So, starting in September (the new January), Rubin dedicated a school year-September through May-to making her home a place of greater simplicity, comfort, and love. Also, while Rubin wanted to be happier at home, she wanted to appreciate how much happiness was there already. A place that, by making her feel safe, would free her to take risks. And what did she want from her home? A place that calmed her, and energized her. "Of all the elements of a happy life," she thought, "my home is the most important." In a flash, she decided to undertake a new happiness project, and this time, to focus on home. She felt homesick, she realized, with love for home itself. Homesick-why? She was standing right in her own kitchen. One Sunday afternoon, as she unloaded the dishwasher, Gretchen Rubin felt hit by a wave of homesickness. In the spirit of her blockbuster #1 New York Times bestseller The Happiness Project, Gretchen Rubin embarks on a new project to make home a happier place. In theory, Windows 10 hardware accelerated GPU scheduling feature passes most GPU scheduling tasks to a dedicated GPU-based scheduling processor, which should free up the CPU a little and can potentially result in a small input lag improvement. While Microsoft says users won’t see any significant changes after activating it now, some believe that the feature will eventually reduce input lag on low-end and mid-core processors.

This will help if you installed an incorrect or mismatched driver. Try to set a system restore point before installing a device driver. It is highly recommended to always use the most recent driver version available. Moreover, check with our website as often as possible in order to stay up to speed with the latest releases. That being said, download the driver, apply it on your system, and enjoy your newly updated graphics card. Therefore, get the package (extract it if necessary), run the setup, follow the on-screen instructions for a complete and successful installation, and make sure you reboot the system so that the changes take effect. When it comes to applying this release, the installation steps should be a breeze, as each manufacturer tries to make them as easy as possible so that each user can update the GPU on their own and with minimum risks (however, check to see if this download supports your graphics chipset). It can improve the overall graphics experience and performance in either games or various engineering software applications, include support for newly developed technologies, add compatibility with newer GPU chipsets, or resolve different problems that might have been encountered. While installing the graphics driver allows the system to properly recognize the chipset and the card manufacturer, updating the video driver can bring about various changes.

Anxiety disorders frequently coexist with insomnia. If at all possible, monitoring for up to 2 weeks is highly recommended because it allows for sleep abnormalities that might show marked day-to-day variability and would more likely be detected by extensive monitoring. 8,9 The log is filled out by the patient shortly after awakening in the morning (see Morin 9(p38) for an example of a sleep log). The use of a sleep log allows for an analysis of day-to-day sleep patterns, such as the time that the patient went to bed, sleep latency, and nighttime awakenings. 11īesides self-rating questionnaires that depend on memory of sleep disturbances, a sleep log or diary can confirm questionable sleep disturbances prospectively. The LSEQ consists of 10 self-rating questions that cover sleep and aberrant sleep behaviors. 10 Another widely used questionnaire is the Leeds Sleep Evaluation Questionnaire (LSEQ). The questions cover sleep quality, sleep problems, sleep medications, and so on, within the past month. The most widely used and validated questionnaire is the 19-question Pittsburg Sleep Quality Index. A number of well-validated sleep questionnaires have been widely used. Self-rating sleep questionnaires and direct clinical interviews are used to obtain a history of potential sleep disorders (eg, insomnia). 3,8,9 Thus, a carefully taken history is an important first step in the assessment of insomnia. Adding to the problem of detecting insomnia is the finding that doctors rarely inquire about insomnia in their patients. Patients rarely report their symptoms of insomnia spontaneously to their doctor. Insomnia is an underrecognized and undertreated problem. It is important to carefully assess for insomnia early in the evaluation of patients with anxiety disorders and to aggressively treat this complicating comorbidity. 4-6 In addition, insomnia as an early symptom in traumatized patients increases the risk of the development of PTSD 1 year later. For example, in patients with PTSD, insomnia is associated with an increased likelihood of suicidal behavior, depression, and substance abuse as well as nonresponsiveness to treatment. 3 Also, there is clear evidence that the presence of insomnia in anxiety disorders is associated with increased morbidity. The presence of insomnia has a deleterious effect on daytime functioning and negative effects on quality of life, including social and work relationships. 1 This is highly relevant because 58% of MDD patients have a lifetime anxiety disorder. The severity of insomnia is increased when an anxiety disorder is comorbid with a major depressive disorder (MDD). The relationship of insomnia to anxiety disorders is also influenced by comorbid major depression. For example, difficulty in falling or staying asleep is a criterion for PTSD, acute stress disorder, and generalized anxiety disorder (GAD). Just how specifically insomnia relates to and possibly affects anxiety disorders is highlighted by the fact that insomnia is one of the defining criteria in a number of the DSM-IV-TR anxiety disorders. The prevalence of comorbid insomnia in anxiety disorders is addressed and the clinical implications associated with insomnia are discussed as well as when and how to treat this important comorbidity. This review focuses on insomnia in the context of anxiety disorders. Insomnia is highly prevalent in psychiatric disorders, and it has significant implications. |
