Matrix vector multiplication matlab3/16/2024 Matlab 2018b Comparison LASTN = maxNumCompThreads(1) ĭisp()Īre there any thoughts on this? As a long-time Matlab user, that’s the Julia that seems most natural to me… but are there other things I’ve missed… preferably without completely obfuscating my code?Īssuming that I have mostly maxed out performance of Julia, I’ve looked into parallel computations. Which isn’t too shabby While not quite as fast as single-threaded Matlab 2018b, we’re on the same order of magnitude - so I chalk this up to different math libraries: R = M * V # Matrix-Matrix multiplication is equivalent to naive approach NVector = 1000 # Usually varies between 1e4 and 2e5įor i = 1:nMatrix # Iterate through the matricesįor j = 1:nVector # Iterate through the vectors NMatrix = 1000 # Usually varies between 1e4 - 1e7, sometimes as high as 1e8 Pseudocode: M(N1,N2,nMatrix) x D(N2,nVector) => R(N1,nVector,nMatrix) But for now I’m just trying to understand performant Julia on this “array of matrices” case. In Matlab I might think of this as a cell-array of matrices and a cell array of vectors. Each matrix is the same size (N1xN2) in my current form, but eventually I’d like to remove this requirement, so that each matrix-vector combination can have arbitrary size. Each matrix multiplies the same, entire list of vectors. However, best practice is to insert the explicit multiplication operator into your expressions.I have a critical portion of code that essentially involves the multiplication of many pre-computed matrices by many pre-computed vectors. Note also that implicit multiplication is interpreted based on the operands, and when it can, Maple parses these as follows: For Vector/Matrix operands this will be interpreted as the `.` (dot) non-commutative multiplication operator, while for Array operands this will be interpreted as the elementwise operator: Note that when multiplying Arrays together (not with Vectors or Matrices), the standard multiplication operator will result in the elementwise product, so the `~` is not necessary: To multiply Vectors and/or Matrices and/or Arrays together using elementwise multiplication, use the standard multiplication operator, `*` followed by the "elementwise" operator, `~`: Implicit multiplication (using a space to mean multiplication) can also be ambiguous. To multiply Matrices and/or Vectors together using the standard Linear Algebra multiplication operation, use the non-commutative multiplication operator, `.` (dot): This error results if Matrices, or a Matrix and a Vector, are multiplied using a commutative multiplication operator, `*`: If instead you want to perform elementwise multiplication, use *~. This display can be modified through the interactive Typesetting Rule Assistant. Note that in 2-D math `*` displays as a center dot: `⋅`, and typing a dot (using the period key) displays as ` (dot) for Vector/Matrix multiplicationĪn expression involving the multiplication of Vectors and/or Matrices (possibly and/or Arrays) has been constructed using the standard multiplication operator, `*`, which is ambiguous. Error, (in rtable/Product) use *~ for elementwise multiplication of Vectors or Matrices use.

7 cardinal movements of labor explained3/16/2024 The umbilical cord lies in the space between them and the lower extremities. In all cephalic presentations, the arms are usually crossed over the thorax or become parallel to the sides. The fetus becomes folded or bent upon itself in such a manner that the back becomes markedly convex the head is sharply flexed so that the chin is almost in contact with the chest the thighs are flexed over the abdomen and the legs are bent at the knees. As a rule, the fetus forms an ovoid mass that corresponds roughly to the shape of the uterine cavity. In the later months of pregnancy, the fetus assumes a characteristic posture described as attitude or habitus as shown in Figure 22-1. If the placenta is implanted in the lower uterine segment, it may distort normal intrauterine anatomy and result in a breech presentation. A peculiarity of fetal attitude, particularly extension of the vertebral column as seen in frank breeches, also may prevent the fetus from turning. One example is a septum that protrudes into the uterine cavity ( Chap. Breech presentation may result from circumstances that prevent normal version from taking place. When the fetus presents as a breech, the three general configurations are frank, complete, and footling presentations and are described in Chapter 28 ( p. The high incidence of breech presentation in hydrocephalic fetuses is in accord with this theory, as the larger fetal cephalic pole requires more room than its podalic pole. It approximates 25 percent at 28 weeks, 17 percent at 30 weeks, 11 percent at 32 weeks, and then decreases to approximately 3 percent at term. 559), the incidence of breech presentation decreases with gestational age. If presenting by the breech, the fetus often changes polarity to make use of the roomier fundus for its bulkier and more mobile podalic pole. As a result, the uterine walls are apposed more closely to the fetal parts. Subsequently, however, the ratio of amnionic fluid volume decreases relative to the increasing fetal mass. Until approximately 32 weeks, the amnionic cavity is large compared with the fetal mass, and the fetus is not crowded by the uterine walls. The cephalic pole is composed of the fetal head only. Although the fetal head at term is slightly larger than the breech, the entire podalic pole of the fetus-that is, the breech and its flexed extremities-is bulkier and more mobile than the cephalic pole. The term fetus usually presents with the vertex, most logically because the uterus is piriform or pear shaped. Note changes in fetal attitude in relation to fetal vertex as the fetal head becomes less flexed. Differences in attitude of the fetal body in (A) vertex, (B) sinciput, (C) brow, and (D) face presentations. Failure to do so can lead to dystocia, as discussed in Chapter 23 ( p. As labor progresses, sinciput and brow presentations almost always convert into vertex or face presentations by neck flexion or extension, respectively. These latter two presentations are usually transient. The fetal head may assume a position between these extremes, partially flexed in some cases, with the anterior (large) fontanel, or bregma, presenting- sinciput presentation-or partially extended in other cases, to have a brow presentation ( Fig. Much less commonly, the fetal neck may be sharply extended so that the occiput and back come in contact, and the face is foremost in the birth canal- face presentation ( Fig. The occipital fontanel is the presenting part, and this presentation is referred to as a vertex or occiput presentation. Ordinarily, the head is flexed sharply so that the chin is in contact with the thorax. Such presentations are classified according to the relationship between the head and body of the fetus ( Fig. Fetal Presentation in 68,097 Singleton Pregnancies at Parkland Hospital Table 22-1 describes the incidences of the various fetal presentations. When the fetus lies with the long axis transversely, the shoulder is the presenting part. Accordingly, in longitudinal lies, the presenting part is either the fetal head or breech, creating cephalic and breech presentations, respectively. It typically can be felt through the cervix on vaginal examination. The presenting part is that portion of the fetal body that is either foremost within the birth canal or in closest proximity to it. Predisposing factors for transverse fetal position include multiparity, placenta previa, hydramnios, and uterine anomalies ( Chap. A longitudinal lie is present in more than 99 percent of labors at term. This lie is unstable and becomes longitudinal or transverse during labor. Occasionally, the fetal and the maternal axes may cross at a 45-degree angle, forming an oblique lie. The relation of the fetal long axis to that of the mother is termed fetal lie and is either longitudinal or transverse.

Yes and no. This system is extremely flexible and powerful as it provides the ability for designers to use virtually the full range of concepts and tools generally only available to programmers. As you use UE4, you'll often find that objects defined using Blueprint are colloquially referred to as just "Blueprints."

Django georgia on my mind chords3/15/2024 In 1948, at the age of five, Harrison enrolled at Dovedale Primary School. In 1949, the family was offered a council house and moved to 25 Upton Green, Speke. The home had an outdoor toilet and its only heat came from a single coal fire. Harrison's biographer Joshua Greene wrote, "Every Sunday she tuned in to mystical sounds evoked by sitars and tablas, hoping that the exotic music would bring peace and calm to the baby in the womb." įor the first four years of his life, Harrison lived at 12 Arnold Grove, a terraced house on a cul-de-sac. When Louise was pregnant with George, she often listened to the weekly broadcast Radio India. Īccording to Boyd, Harrison's mother was particularly supportive: "All she wanted for her children is that they should be happy, and she recognised that nothing made George quite as happy as making music." Louise was an enthusiastic music fan, and she was known among friends for her loud singing voice, which at times startled visitors by rattling the Harrisons' windows. He had one sister, Louise (16 August 1931 – 29 January 2023), and two brothers, Harold (born 1934) and Peter (20 July 1940 – 1 June 2007). Harold was a bus conductor who had worked as a ship's steward on the White Star Line, and Louise was a shop assistant of Irish Catholic descent. He was the youngest of four children of Harold Hargreaves (or Hargrove) Harrison (1909–1978) and Louise (née French 1911–1970). Harrison was born at 12 Arnold Grove in Wavertree, Liverpool, on 25 February 1943. He left an estate of almost £100 million.Įarly years: 1943–1958 Harrison's place of birth and first home – 12 Arnold Grove His remains were cremated, and the ashes were scattered according to Hindu tradition in a private ceremony in the Ganges and Yamuna rivers in India. A lifelong cigarette smoker, Harrison died of numerous cancers in 2001 at the age of 58, two years after surviving a knife attack by an intruder at his home, Friar Park. In the following year he married Olivia Arias, with whom he had a son, Dhani. Harrison's first marriage to model Pattie Boyd in 1966 ended in divorce in 1977. He is a two-time Rock and Roll Hall of Fame inductee – as a member of the Beatles in 1988, and posthumously for his solo career in 2004. Rolling Stone magazine ranked him number 31 in their 2023 list of greatest guitarists of all time. A prolific recording artist, he was featured as a guest guitarist on tracks by Badfinger, Ronnie Wood, and Billy Preston, and collaborated on songs and music with Dylan, Eric Clapton, Ringo Starr, and Tom Petty. In 1988, he co-founded the platinum-selling supergroup the Traveling Wilburys. Harrison released several best-selling singles and albums as a solo performer. He co-founded HandMade Films in 1978, initially to produce the Monty Python troupe's comedy film The Life of Brian (1979). In his role as a music and film producer, Harrison produced acts signed to the Beatles' Apple record label before founding Dark Horse Records in 1974. He also organised the 1971 Concert for Bangladesh with Indian musician Ravi Shankar, a precursor to later benefit concerts such as Live Aid. After the band's break-up in 1970, Harrison released the triple album All Things Must Pass, a critically acclaimed work that produced his most successful hit single, " My Sweet Lord", and introduced his signature sound as a solo artist, the slide guitar. Having initiated the band's embrace of Transcendental Meditation in 1967, he subsequently developed an association with the Hare Krishna movement. Harrison's earliest musical influences included George Formby and Django Reinhardt subsequent influences were Carl Perkins, Chet Atkins and Chuck Berry.īy 1965, he had begun to lead the Beatles into folk rock through his interest in Bob Dylan and the Byrds, and towards Indian classical music through his use of Indian instruments, such as the sitar, which he had become acquainted with on the set of the film Help! He played sitar on numerous Beatles songs, starting with " Norwegian Wood (This Bird Has Flown)". His songs for the group include " Taxman", " Within You Without You", " While My Guitar Gently Weeps", " Here Comes the Sun" and " Something". Although the majority of the band's songs were written by John Lennon and Paul McCartney, most Beatles albums from 1965 onwards contained at least two Harrison compositions. Sometimes called "the quiet Beatle", Harrison embraced Indian culture and helped broaden the scope of popular music through his incorporation of Indian instrumentation and Hindu-aligned spirituality in the Beatles' work. George Harrison MBE (25 February 1943 – 29 November 2001) was an English musician, singer and songwriter who achieved international fame as the lead guitarist of the Beatles. Memorial pictures for loved ones3/15/2024 There are two ways to organize your stories, chronologically or by theme. Ever Loved Free Memorial Website (allows you to raise funds if you want, too).Here are some online resources for creating a memorial space in the cloud: Or consider printing a physical keepsake book filled with stories, or a memorial scrapbook with photos and notes and more. Gather all of your stories in an app or website and store them on the cloud. Write down each memory and save them all as a collection to be passed down to your children and grandchildren (as our next point suggests). It’s your family history, the story of your life and the life of your beloved. Stories are meant to be heard and treasured. These might even be stories that you have never heard before. Ask family and friends to share stories.įamily and friends are bound to know stories about your loved one. Just because they are gone, you haven’t stopped loving them. Memorializing your loved one is about expressing your heart. While all these memorial projects and tributes (which we’ll get into further down) are important, nothing is as important as continuing to acknowledge their existence by saying their name, talking about them, and sharing what they meant to you. Talking about and remembering your loved ones is a way to keep them close to you. Don’t be afraid to remember them, and talk about them. It’s a way to highlight their life – to show the world that your loved one’s life was essential and made a difference. Memorializing a loved one is to celebrate them.

There are many ways to pay tribute to your loved one. You can do a major, more intentional tribute each year on their “ death anniversary” date, or a few small projects at various times throughout the year. Pick one major project or a few smaller ones. But you can help work through the pain and the grief by memorializing your beloved. It hurts so badly to lose someone we love. Verilog binary to decimal decoder3/15/2024 Suppose the column for segment a shows the different combinations for which it is to be illuminated. In the truth table, there are 7 different output columns corresponding to each of the 7 segments. The figure below shows the truth table of a BCD to seven-segment decoder with common cathode display. As we mentioned above that for a common cathode seven-segment display, the output of decoder or segment driver must be active high in order to glow the segment. The truth table for the decoder design depends on the type of 7-segment display. Image Resource Link: Step 2: The second step involves constructing the truth table listing the 7 display input signals, decimal number and corresponding 4 digit binary numbers. For example, decimal number 1 would command a combination of b and c (refer the diagram given below). A truth table is constructed with the combination of inputs for each decimal number. A 7-segment display consists of an arrangement of LEDs in an ‘H’ form. Step 1: The first step of the design involves analysis of the common cathode 7-segment display. A common cathode 7 segment display consists of 8 pins – 7 input pins labeled from ‘a’ to ‘g’ and 8 th pin as common ground pin.īack to top 7 Segment Display Decoder Circuit Design For example few basic Boolean algebra rules to be followed are the complementary law, associative law, De-Morgan’s law etc.Ī 7 segment LED display consists of an arrangement of 8 LEDs such that either all the anodes are common or cathodes are common. To understand the design and operation of these logic circuits, one needs to have a good knowledge about Boolean algebra and logic gates. Best examples of such circuits are Encoders and Decoders, Multiplexers and De-multiplexers, Adders, Subtractors etc. The output of a combinational logic circuit depends only on the present state of the inputs and nothing else. A combinational logic circuit is a system of logic gates consisting of only outputs and inputs. It can be a simple binary to decimal decoder or a BCD to 7 segment decoder.Īnother relevant section is the combinational logic circuitry. A decoder is a combinational circuit which is used to convert a binary or BCD (Binary Coded Decimal) number to the corresponding decimal number. The first and foremost aspect of this circuit is decoder.

However to display the characters and numbers (in order to produce the decimal readout), seven-segment displays are most commonly used. Generally, LCD and LED segments provide the display output of numerical numbers and characters. Most often seven-segment displays are used to display the digits in digital watches, calculators, clocks, measuring instruments and digital counters, etc. Applications of Display Decoder Circuit.7 Segment Display Decoder Circuit Design. Happy birthday song lyrics stevie wonder3/15/2024 The movement to officially enact MLK day finally succeeded in 1983, when the bill passed the Senate 78 to 22. In the later years leading up to the bill’s adoption, Wonder committed to significant rallying for the holiday including a four-month tour to publicize the drive for MLK day concluding in a rally on the National Mall in Washington, D.C. King’s writings and be informed on the totality of his work and views. King omits much of his stances on issues including his longstanding critique of police brutality. Now lauded as one of our most significant civil rights leaders, mainstream information about Dr. government and labeled a communist because of the work he did to fight for civil rights. While our history textbooks would tell us otherwise, it’s important to remember that while he was alive, Dr. King had followed a philosophy of “action-oriented Marxism” that was not “compatible with the concepts of this country (Roberts, 1983).” There was significant opposition to the bill, in particular from Sen. Wonder wrote and later recorded “Happy Birthday” and it was included on his 1980 album, Hotter Than July. King’s birthday and support the campaign for declaring his birthday a national holiday. Eventually, Wonder wrote “Happy Birthday” to commemorate Dr. Conyers in support of a bill to declare a national holiday in King’s honor. King when he was 15 and quickly joined Rep.

Martin Luther King, Jr day, this month’s song is Stevie Wonder’s “Happy Birthday.” For as long as I can remember, I have always known the “Black Happy Birthday Song,” but it wasn’t until I was an adult that I learned how that song came to be. The lesson plans I’ll be sharing will include a variety of learning pathways that you can take back to your classroom. Don’t take my – or anyone else’s – word for it! You need to do that work. Of course, you have to do your own due diligence, too: hold yourself to the standard that you will thoroughly know the musical content that you present to learners beyond just a surface level understanding. To support you, every month, I’ll be sharing a “Song of the Month,” a piece of musical content that I have researched along with a lesson plan. It’s also true that our learners deserve better content right now it’s up to us to make that happen, we can’t wait for others to do this for us. It’s unfortunate that we don’t have more music education curriculum resources that prioritize these things. We all know the importance of thoroughly knowing the background, history, and context of the songs and musicians we teach AND music educators absolutely need more resources that prioritize diversity, cite their sources, and give proper context to repertoire. This week I’m excited to share some of that work with you! Introducing Song of the Month I am an artist and creative at heart designing lessons & learning experiences for me is a part of my artistic craft as an educator. Hey music educators! Those of you who know me already know how much I love creating curriculum materials. Template project planner excel3/15/2024 Adding more colors is possible, but that would require more Excel experience. Adding more is possible but would require you to create the new data series yourself (you can't just insert rows for more milestones like you can with the tasks).Ĭan I Add More Colors? This project timeline is set up to allow up to 6 different color choices. The template lets you show up to 4 milestones. You can edit the milestone labels and dates via the data table. In the above example you will see 3 milestones as vertical lines. Milestones: With any project timeline, you will most likely want to define at least a couple key milestones. Another common way to group tasks within a project timeline is by key organization function, such as Marketing, Design, Testing, Manufacturing, Finance, Sales, Quality Assurance, Legal, etc. However, there are other ways to use this type of timeline. The example above shows some of the steps in a product development cycle (Concept Development, System Design, Detail Design, Testing and Refining, Production, etc.), with different colors representing different phases of the cycle. You can insert and delete tasks by just inserting or deleting rows in the spreadsheet's data table. This makes it easy to identify the different phases or categories of tasks. Grouping Tasks Using Different Colors: One of the key features of this template is the ability to choose a different color for the bars in the timeline via a drop-down box in the Color column. Test typing speed online3/15/2024 Guess you Made 60 correct insertions out of 120 Total Insertions of words then result Accuracy would be (60/120)*100=50%. For Example, you made Error in 10 words in 2 Minutes time Slot so your Error Rate would be 10/2=5 Words.Īccuracy is attained by dividing the correct words by total words after that multiply the result with 100 for getting the Percentage. Suppose your GWPM speed is 20 but you made Error in 5 words so your speed will be 20-5=15 Net Word Per Minute.Įrror Rate is Deduced by Dividing Incorrect entries by Total Time(in Minutes). Net Word Per Minute is the actual Speed on Which you can Trust completely because it unlike GWPM take into Consideration the Error Rate, in other words, the number of words in which you made Error in a given time slot so, that final Speed will be the outcome of Accuracy and GWPM taken into Deliberation. For example your 100 characters or Keystrokes in a minute then your GWPM would be 100/5=20 (WPM), Gross. These formulas are considered Standard Formulas for Calculating Speed.įirst of all, count how many characters you typed in the test then divide that number by 5 whatever result you get to divide it further by total time in minutes. Any increase in your typing speed will help you have a better experience when you are using. Whether you are a good typist or not, it will help you get better. Your wpm can easily go from 15 wpm to 40 wpm. These Formulas are used to Calculate Speed of Typing Test Accurately. I believe that if you practice 5 minutes per day during a month you will greatly improve your speed. As soon as the time is over you will get your overall performance card so judge your skills accordingly. English Typing speed counting is based on a generally held method, in which five characters will be counted as a single word. During the English Typing Test, you will get your typing progress as WPM (Word Per Minute) value. In the Progress bar situated below Typing test will show real-time data such as typing speed, accuracy, Error rate etc. This English Typing Test will show you your typing speed, accuracy, error rate or incorrectly typed words. If you typed an incorrect word it will be shown in red colour and your speed will decrease accordingly so try to make fewer mistakes.
