A circular note is a document request by a bank to its foreign correspondents to pay a specified sum of money to a named person. The person in whose favour a circular note is issued is furnished with a letter containing the signature of an official of the bank and the person named called a letter of indication, which is usually referred to in the circular note, and must be produced on presentation of the note. Circular notes are generally issued against a payment of cash to the amount of the notes, but the notes need not necessarily be cashed, but may be returned to the banker in exchange for the amount for which they were originally issued. A forged signature on a circular note conveys no right, and as it is the duty of the payer to see that payment is made to the proper person, he cannot recover the amount of a forged note from the banker who issued the note.

For most of England and Wales, it marked the abolition of the old Grammar schools in the United Kingdom grammar schools and secondary modern school secondary moderns , and the Eleven Plus examination. Circular 10 65 was the initiative of recently appointed Education Secretary Anthony Crosland it is sometimes called the Crosland Circular . It reflected the Labour government s view that the existing Tripartite System of education was flawed, and had to be replaced with comprehensive schools , which had been increasing in number over the previous sixteen years. Drafting During the Circular s drafting, there was a debate in Whitehall over how strongly worded the Circular ought to be. Secondary education was not under the direct control of the DES, and all changes had to be implemented by the local authorities. Those firmly in favour of the comprehensive system believed that the Circular should convert all schools into comprehensives. Those preferring to preserve the balance of power between the DES and LEAs thought that the word should be request .

In probability and statistics , a circular distribution or polar distribution is a probability distribution of a random variable whose values are angles, usually taken to be in the range nowrap 0, 2&pi . ref name D Dodge, Y. 2006 The Oxford Dictionary of Statististical Terms , OUP. ISBN 0 19 920613 9 ref A circular distribution is often a continuous probability distribution , and hence has a probability density , but such distributions can also be discrete probability distribution discrete , in which case they are called circular lattice distributions . ref name D Circular distributions can be used even when the variables concerned are not explicitly angles the main consideration is that there is not usually any real distinction between events occurring at the lower or upper end of the range, and the division of the range could notionally be made at any point. Graphical representation If a circular distribution has a density math p phi qquad qquad 0 le phi 2 pi , , math it can be graphically represented as a closed curve math x phi ,y phi r phi cos phi, , r phi sin phi , , math where the radius math r phi , math is set equal to math r phi a b p phi , , math and where a and b are chosen on the basis of appearance. Example By computing the probability distribution of angles along a handwritten ink trace, a lobe shaped polar distribution emerges. The main direction of the lobe in the first quadrant corresponds to the slant handwriting slant of handwriting see graphonomics .

Confusing date December 2006 In software engineering , a circular dependency is a relation between two or more modules which either directly or indirectly depend on each other to function properly. Overview Circular dependencies are natural in many domain model s where certain objects of the same domain depend on each other. However, in software design circular dependencies between larger software modules are considered an anti pattern because of their negative effects. Problems of circular dependencies Circular dependencies can cause many unwanted effects in software programs. Most problematic from a software design point of view is the tight coupling of the mutually dependent modules which reduces or makes impossible the separate re use of a single module. Circular dependencies can cause a domino effect when a small local change in one module spreads into other modules and has unwanted global effects program errors, compile errors . Circular dependencies can also result in infinite recursions or other unexpected failures.

Moreover, it is usually assumed that u u v v 1 and u v 0, where dot denotes the canonical scalar product on R sup 3 sup , i.e. u and v are unit length and mutually perpendicular . The map I R sup 3 sup is called the base curve for the circular surface and the two maps u , v I R sup 3 sup are called the direction frame for the circular surface. For a fixed t sub 0 sub I the image of t sub 0 sub , is called a generating circle of the circular surface. ref S. Izumiya, K. Saji, and N.
