Background and Objectives: Work sampling is a useful technique to characterize how employees allocate their work time to various activities. Given the value of nurses’ time for quality health care delivery, characterization of nursing time distribution may provide useful information for optimal use of nursing staff. The purpose of the present study was to explore time allocatio...

for considering and evaluating the economic impacts of sugar beet research on the shift of sugar supply, we need to estimate the parameter of supply shift. having developed an appropriate methodology and using the results of breeding research collected from the main stations of sugar beet research acrossiranfor the period of 1982-2003, the supply shift parameter for sugar was estimated.  this p...

We study algebraic feedback shift registers (AFSRs) based on quotients of polynomial rings in several variables over a finite field. These registers are natural generalizations of linear feedback shift registers. We describe conditions under which such AFSRs produce sequences with various ideal randomness properties. We also show that there is an efficient algorithm which, given a prefix of a s...

The proposed Built-In Self-Diagnosis method (BISD) is based on the standard BIST architecture and can be integrated with recent, commercial DFT techniques, LP-TPG for in-field testing and in-field diagnostic data collection. To find maximum faults, structural diagnosis is used which does reveal the diagnostic information. A new low power test pattern generator using a linear feedback shift regi...

 Introduction: Controversies exist in publications about the association between shift work and hypertension. This study aimed to explore the relationship between shift work and the level of systolic and diastolic blood pressure as well as serum cholesterol among nurses in Kerman province, Southeast, Iran.   Materials and Methods : In this historical cohort study 100 hospital nurse...

We introduce a new kind of word-oriented linear feedback shift register called σ−LFSR which is constructed with the instructions of the modern processor and have fast software implementation. We offer an algorithm to search for good primitive σ−LFSR. In particular, we give two examples HHZ-1 and HHZ-2 and compare their efficiency and security with those of the LFSRs appearing in stream ciphers ...

Feedback with carry shift registers (FCSRs) are arithmetic analogs of linear feedback shift registers (LFSRs). In this paper we survey some of the basic properties of FCSRs. For comparison, we first review some basic facts about LFSRs. We then define FCSRs and discuss their relation to the N -adic numbers. This leads to the analysis of periodicity of FCSR sequences, their exponential representa...
