In the process of district energy system (DES) operation and dispatching, there are various uncertainties brought by strong coupling equipment fluctuation internal external surroundings, these uncertain parameters often correlated. this paper, an improved affine arithmetic-based method is proposed to solve economic dispatching problem DES with correlated uncertainties. First, optimal model cons...

This work introduces the idea of data dependent video coding for low power. Algorithms for the Discrete Cosine Transform (DCT) and its inverse are introduced which exploit statistical properties of the input data in both the space and spatial frequency domains in order to minimize the total number of arithmetic operations. Two VLSI chips have been built as a proof-of-concept of data dependent p...

Moore’s interval arithmetic always provides the same results of arithmetic operations, e.g. [1,3]+ [5,9] = [6,12]. But in real life problems, the operation result can be different, e.g. equal to [4,7]. Therefore, real problems require more advanced arithmetic. The paper presents (on example of the division) an arithmetic of intervally-precisiated values (IPV-arithmetic) and its main advantages....

The paper begins with an axiomatic definition of rounded arithmetic. The concepts of rounding and of rounded arithmetic operations are defined in an axiomatic manner fully independent of special data formats and encodings. Basic properties of floating-point and interval arithmetic can directly be derived from this abstract model. Interval operations are defined as set operations for elements of...

The demand of low power high speed circuits are in demand with the increasing universal growth in electronic system and the loss of information is not acceptable as with single loss of a bit information the energy loss is equal to kTlog2 joules/bit. Reversible logic can be of prominent interest to design low power arithmetic and data path units for digital signal processing applications, such a...

We propose a fast and simple binary arithmetic coder, STT-coder, in which arithmetic operation of dividing the probability interval can be done using a state transition table. In order to simplify the state transition table by omitting to retain the both of the bottom address of the valid interval and renormalized interval, renormalization is mostly executed together with the flush operation of...

This paper introduces the segmentation of Neisseria bacterial meningitis images. Images is an operation identifying homogeneous location in a digital image. The basic idea behind called thresholding, which be classified as single thresholding and multiple thresholding. To perform images segmentation, transformations morphological operations processes are used to segment images, well image trans...

Using an identity for effective resistances, we find a relationship between the arithmetic-geometric index and the global ciclicity index. Also, with the help of majorization, we find tight upper and lower bounds for the arithmetic-geometric index.

units (adders, ALUs, multipliers, dividers) are essential to fault-tolerant computer designs. Some researchers based early design schemes for such units on arithmetic residue codes.1 Others proposed parity prediction schemes for the same purpose.2 These schemes compute the output operand’s parity as a function of the operator’s internal carries and of the input operands’ parities. The basic dra...
