After evaluating the existing vessel foundation we found out that vertical dowels between pedestal and mat are NOT adequate. As the most cost effective repair we are thinking of drilling (32)~1-1/8”Ø x 90” deep holes between existing dowels and anchor bolts and setting #8 rebars with HILTI HIT HY 150 ADHESIVE (please see attached sketch). Our main concern is if drilling new holes will disturb/weaken existing anchor bolts. Your comments/suggestions would be appreciated. Thank you, iv

As the semiconductor industry races to keep pace with Mooreâ€™s Law, which regards the doubling of transistors per square inch on integrated circuits, lithography hardware systems are not always able to provide a quality image for creating circuits. Download Now
Current integrated circuit (IC) designs are complex, which can result in different voltages being located close to one another. To prevent time dependent dielectric breakdown (TTDB), it is essential to incorporate space rules within IC design. Download Now
