Partially balanced network designs and graph codes generation

open access: yesAIMS Mathematics, 2022
Partial balanced incomplete block designs have a wide range of applications in many areas. Such designs provide advantages over fully balanced incomplete block designs as they allow for designs with a low number of blocks and different associations. This

Block combination–based asynchronous wake-up schedule in wireless sensor networks

open access: yesInternational Journal of Distributed Sensor Networks, 2017
In wireless sensor networks, when sensor nodes are operated with different ratios of active slots, this is called asymmetric duty cycles. Furthermore, cycles with the same ratio of active slots per cycle for all nodes are called symmetric duty cycles. In

Construction of Some Circular Regular Graph Designs in Blocks of Size Four Using Cyclic Shifts

open access: yesJournal of Statistical Theory and Applications (JSTA), 2020
Circular regular graph designs play an important role in the design of experiments where most of the balanced incomplete block designs require a large number of blocks.

Comparison Between some Methods of Tackling the Lack of Experimental Units Needed for Application of Factorial Experiments [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2011
Most of the time the researcher confronts a decrease in the experimental units required when applying a certain design, this problem appears especially when conducting the factorial experiments which mostly need great numbers of experimental units, to ...

The influence of yeasts and copper sulphate addition on aroma of Viennese Rheinriesling wines

open access: yesOENO One, 2021
The influence of two yeast strains and the addition of copper sulphate on the aroma of Riesling wines was monitored. Two commercially available yeast strains, Zymaflore VL3 and X-Pure, were applied.

New Combinatorial Construction Techniques for Low-Density Parity-Check Codes and Systematic Repeat-Accumulate Codes [PDF]

open access: yes, 2012
This paper presents several new construction techniques for low-density parity-check (LDPC) and systematic repeat-accumulate (RA) codes. Based on specific classes of combinatorial designs, the improved code design focuses on high-rate structured codes ...
