BACKGROUND The current standard for treating complete tears of the anterior cruciate ligament (ACL) is reconstruction, which requires reaming a tibial tunnel. Based on recent anatomic and biomechanical studies, this reconstruction tunnel may cause injuries to the anterior meniscal root attachments. PURPOSE/HYPOTHESIS The purpose was to determine if injuries occurred to the anteromedial (AM) a...
The textit{QIF} (Quadrant Interlocking Factorization) method of Evans and Hatzopoulos solves linear equation systems using textit{WZ} factorization. The WZ factorization can be faster than the textit{LU} factorization because, it performs the simultaneous evaluation of two columns or two rows. Here, we present a method for computing the real and integer textit{WZ} and textit{ZW} factoriz...
Ice accumulation causes great risks to aircraft, electric power lines, and wind-turbine blades. For the ice on structural surfaces, adhesion force is a crucial factor, which generally has two main sources, for exampple, electrostatic mechanical interlocking. Herein, we present that surface acoustic waves (SAWs) can be applied minimize by simultaneously reducing interlocking, generating interfac...
In a previous publication the authors proposed a continuous model for describing the mechanical behaviour of ‘Running Bond’ masonry walls. Here a different masonry structure is considered. This structure is ‘bi-atomic’ in the sense that its pattern consists in two kind of blocks with different. The homogenization by differential expansions technique is used for obtaining an equivalent Cosserat ...
The Long Island Railroad (LIRR) operates one of the busiest passenger rail networks in the US, and for over 100 years, the Jamaica terminal is essential to maintain passenger trains to and from Manhattan. Over this time, the patterns of ridership have changed dramatically and there is a new terminal stop at Grand Central Station for LIRR passengers. The “East Side Access” will provide the LIRR ...
Given a family I of intervals, two intervals in I interlock if they overlap but neither of them strictly contains the other. A set of intervals in which every two are related in the reeexive transitive closure of the interlock relation is referred to as an interlocking set. The task of determining the maximal interlocking sets of I arises in numerous applications including traac control, robot ...
A railway interlocking system (RIS) plays a vital role in the safe transportation of a railway system. It is responsible for the safe routes of trains making sure that each train movement follows the other in a proper and safe sequence. Detailed verifications and evaluations are mandatory before deploying an RIS, since it is a safety critical system (SCS). But the increasing complexity of the R...
BACKGROUND Plate osteosynthesis is the most commonly used technique for the treatment of diaphyseal forearm fractures in adults. However, application of a plate can disrupt the periosteal blood supply and necessitates skin incisions that may be unsightly, and there is a risk of refracture if the implant is removed. The purpose of this study was to assess the early results of the use of a contou...
