PURPOSE To report the preoperative best-corrected visual acuity (BCVA) and foveal thickness (FT) values that lead to a postoperative decimal BCVA of ≥1.0 after surgical removal of an idiopathic epiretinal membrane (ERM). METHODS This is a retrospective case series of 73 eyes that underwent surgery for removal of an idiopathic ERM. All eyes had been treated by a single surgeon using a 25-gauge...

Steganography is the art and science of hiding important information by embedding message within other file. In this paper, a new technique to hide text message in image by using what is called image steganography. By representing the ASCII code decimal value of each character, in the secret message, as a set of separated single decimal-digit, also represent each decimal pixel value in the steg...


 Este artículo analizará «Sistema decimal entre los antiguos peruanos», el ensayo de Ricardo Palma en que arguye inkas usaron sistema a partir un análisis filológico Ollantay y Comentarios reales del Inca Garcilaso la Vega. Se examinará por qué este escrito es no tradición al cotejar sus elementos constituyentes con las características tal como Gómez Martínez teoriza, incluyendo discursiv...

This note discusses the main issues in performing correctly rounded decimal-to-binary and binary-to-decimal conversions. It reviews recent work by Clinger and by Steele and White on these conversions and describes some efficiency enhancements. Computational experience with several kinds of arithmetic suggests that the average computational cost for correct rounding can be small for typical conv...

A scheme is presented and software is documented for representing as integers input decimal numbers that have been stored in a computer as double precision floating point numbers and for carrying out multiplications, additions and subtractions based on these numbers in an exact manner. The input decimal numbers must not have more than nine digits to the left of the decimal point. The decimal fr...

OBJECTIVE The purpose of this proof-of-concept study was to assess the feasibility of using a generic health measure to create coded functional status indicators and compare the characterization of a stroke population using coded functional indicators and using health-related quality-of-life summary measures alone. DESIGN Multiple raters assigned International Classification of Functioning, D...

Decimal computer arithmetic is experiencing a revived popularity, and there is quest for highperformance decimal hardware units. Successful experiences on binary computer arithmetic may find grounds in decimal arithmetic. For example, the traditional fully redundant (i.e., the result and both of the operands are represented in a redundant format) and semi-redundant (i.e., the result and only on...

This paper introduces two novel architectures for parallel decimal multipliers. Our multipliers are based on a new algorithm for decimal carry–save multioperand addition that uses a novel BCD–4221 recoding for decimal digits. It significantly improves the area and latency of the partial product reduction tree with respect to previous proposals. Decimal floating-point multiplication is important...

A numerical optical processor is described that performs operations in residue arithmetic. The position coding used to represent decimal and residue numbers allows one to describe the various conversions and operations in a correlation formulation. This description of residue arithmetic leads directly to novel residue adder and decimal/residue/decimal converter designs, which are described and ...

Parallel decimal arithmetic capability is becoming increasingly attractive with new applications of computers in a multiprogramming environment. The direct production of decimal sums offers a significant improvement in addition over methods requiring decimal correction. These techniques are illustrated in the eight-digit adder which appears in the System/360 Model 195.
