background and aims. maintenance of interdental soft tissue and the need for aesthetics are increasingly recognized as important criteria for implant success. the aim of this prospective clinical study was to compare the peri-implant and prosthetic conditions for single-tooth implants, placed according to the immediate (im) and the delayed (de) placement protocols at 18-month follow-up examinat...

Routability is one of the most critical metrics to evaluate the quality of standard cell placement In xed die place ment white space can be used to alleviate congestion and achieve better routability In this paper we propose a new global approach to white space allocation problem for xed die placement and an e ective algorithm to allocate white space according to congestion distribution The pro...

Traditional placement algorithms for FPGAs are normally carried out on a fixed clustering solution of a circuit. The impact of clustering on wirelength and delay of the placement solutions is not well quantified. In this paper, we present an algorithm named SCPlace that performs simultaneous clustering and placement to minimize both the total wirelength and longest path delay. We also incorpora...

The amount of hydrocarbon recovered can be considerably increased by finding optimal placement of non-conventional wells. For that purpose, the use of optimization algorithms, where the objective function is evaluated using a reservoir simulator, is needed. Furthermore, for complex reservoir geologies with high heterogeneities, the optimization problem requires algorithms able to cope with the ...

We discuss the single-input pole placement problem (SIPP) and analyze how the conditioning of the problem can be estimated and improved if the poles are allowed to vary in specific regions in the complex plane. Under certain assumptions we give formulas as well as bounds for the norm of the feedback gain and the condition number of the closed loop matrix. Via several numerical examples we demon...

Implant restorations delivered according to the Brånemark protocol have proven to be highly predictable. To shorten the length of treatment associated with the Brånemark protocol, as well as to preserve soft and hard tissues, newer protocols have focused on reducing or even eliminating the time between tooth extraction and implant placement and between implant placement and prosthetic restorati...

Indications for tympanostomy tube (TT) placement in children with chronic serous effusions and hearing loss are fairly well established. The use of TTs for children with recurrent acute otitis media (rAOM) has not been studied as extensively as for those with hearing loss from middle-ear effusions. There is a subset of children who fall outside established guidelines for either of the preceding...
