Recent Advances in Aeroacoustics
Acoustics is one of the oldest examples of applied research, long before the term was even coined: witness the concept of musical scales by the ancient Greeks and the construction of musical and other sound instruments in most civilizations through the ages. Compared with sound in the strict sense of small pressure perturbations in a homogeneous, non-dissipative medium at rest, modern aeroacous...
متن کاملOn some recent advances in shape optimization
In this Note we give a short review on recent developements in shape optimization. We explain how the generic non-existence of solutions can be circumvent. Either one can impose some geometric restrictions on the class of admissible domains to get existence (we then explain how to write the usual optimality conditions), or generalized designs are allowed which leads to relaxation by homogenizat...
متن کاملSome Recent Advances in Rheumatology
Although rheumatic problems are not fatal, they are among the more frequent causes of morbidity and long term disability in the population. They range in severity from minor aches and pains affecting the joints and related structures, to serious and potentially fatal conditions. Most of the rheumatological patients have to be followed up and given treatment on a chronic basis. Accordingly, rheu...
متن کاملRecent Advances in Hemophilia Gene Therapy
Heterogeneous loss of function mutations at F8 and F9 genes causes X-linked recessive bleeding disorders, hemophilia A (HA) and hemophilia B (HB), respectively. HA is clinically indistinguishable from HB and accounts for more than 80% of hemophilia cases; the former affects 1/5000 and the latter 1/25000 male births worldwide. In Iran, it is estimated that around 4300 HA and 900 HB patients are ...
متن کاملON THE FUZZY SET THEORY AND AGGREGATION FUNCTIONS: HISTORY AND SOME RECENT ADVANCES
Several fuzzy connectives, including those proposed by Lotfi Zadeh, can be seen as linear extensions of the Boolean connectives from the scale ${0,1}$ into the scale $[0,1]$. We discuss these extensions, in particular, we focus on the dualities arising from the Boolean dualities. These dualities allow to transfer the results from some particular class of extended Boolean functions, e.g., from c...
