background & aims: thuracolumbar unstable fractures (t, l.u.f) are common after spine truma. posterior pedicular fixation is a technique that is use for fixation of these fractures. this study evaluates the accuracy of pedicular screw placement in t, luf with the assistance of plain radiography in operation rooms. materials & methods: this study is a case-control and analytical study. 35 patien...

discussion this segmental ridge-split procedure with gradual bone expansion provides a quicker method wherein an atrophic ridge can be predictably expanded and eliminating the need for a second surgical site. this technique also shows that immediate implantation in split ridge of mandible can be performed. introduction narrow alveolar ridges especially in posterior mandibular remains a serious ...

purpose: to determine the efficacy of primary placement of a titanium sleeve and peg on hydroxyapatite (ha) orbital implants. methods: this retrospective non-comparative interventional case series was performed on 34 patients undergoing enucleation. a standard enucleation technique with primary ha implantation was performed, in which titanium sleeve and peg were placed primarily during the init...

In the most recent heuristic methods, the high potential buses for capacitor placement are initially identified and ranked using loss sensitivity factors (LSFs) or power loss index (PLI). These factors or indices help to reduce the search space of the optimization procedure, but they may not always indicate the appropriate placement of capacitors. This paper proposes an efficient approach for t...

Autonomous object placement is a central task in many military and industrial applications. Deciding where to place an object, or placement planning, is a crucial reasoning task within object placement. Placement planning is especially challenging in 3D worlds. In previous work we developed approaches for placement planning that perform well but require manually-engineered knowledge. Consequent...

Placement is the process of determining the locations of circuit devices on a die surface. It is an important stage in the VLSI design flow, because it affects routability, performance, heat distribution, and to a less extent, power consumption of a design. Traditionally, it is applied after the logic synthesis stage and before the routing stage. Since the advent of deep submicron process techn...

Sub-resolution assist features (SRAFs) provide an absolutely essential technique for critical dimension (CD) contro1 and process window enhancement in subwavelengt h lithography. However, as focus levels change during manufacturing, CDs at a given Gilegai” pitch can fail t o achieve manufacturing tolerances required for adequate yield. Furthermore, a d o p tion of off-axis illumination (OAI) an...

Communication placement analysis is an important step in the compilation of data-parallel programs. However, to simplify the placement analysis, previous techniques ignored most machine-dependent resource constraints. This paper demonstrates the necessity of incorporating resource constraints in ensuring the correctness of the communication placement. It presents a new placement analysis techni...
