Doctor of Letters (D.Litt., Litt.D., Latin: Litterarum Doctor or Doctor Litterarum) also termed "Doctor of Literature" in some countries is a terminal degree in the arts, humanities and social sciences that, depending on the country, is a higher doctorate after the Doctor of Philosophy (Ph.D.) degree or equivalent to a higher doctorate, such as the Doctor of Science (Sc.D. or D.Sc.) or Doctor ...
The Doctor of Literature and Philosophy, or DLitt et Phil, is a doctoral advanced research degree offered by a number of leading universities in South Africa, such as UJ, the University of Johannesburg; and UNISA, the University of South Africa. The degree is equivalent to a PhD and is generally offered in arts, human science ( humanities ...
Google Classroom is a free blended learning platform developed by Google for educational institutions that aims to simplify creating, distributing, and grading assignments. The primary purpose of Google Classroom is to streamline the process of sharing files between teachers and students. [3] As of 2021, approximately 150 million users use ...
ln (r) is the standard natural logarithm of the real number r. Arg (z) is the principal value of the arg function; its value is restricted to (−π, π]. It can be computed using Arg (x + iy) = atan2 (y, x). Log (z) is the principal value of the complex logarithm function and has imaginary part in the range (−π, π].
Dalit History Month is an annual observance as a way of remembering important people and events in the history of the Dalits or Scheduled Castes and Scheduled Tribes. It is celebrated in April all over the world by Ambedkarites, followers of Dr. B.R. Ambedkar.
The Defense Language Institute Foreign Language Center (DLIFLC) traces its roots to the eve of United States entry into World War II, when the U.S. Army established a secret school at the Presidio of San Francisco with a budget of $2,000 to teach the Japanese language. Classes began 1 November 1941, with four instructors and 60 students in an ...
Discrete logarithm. In mathematics, for given real numbers a and b, the logarithm log b a is a number x such that bx = a. Analogously, in any group G, powers bk can be defined for all integers k, and the discrete logarithm log b a is an integer k such that bk = a. In number theory, the more commonly used term is index: we can write x = ind r a ...
In probability theory, a log-normal (or lognormal) distribution is a continuous probability distribution of a random variable whose logarithm is normally distributed. Thus, if the random variable X is log-normally distributed, then Y = ln (X) has a normal distribution. [2] [3] Equivalently, if Y has a normal distribution, then the exponential ...
