Imagers based on focal plane arrays (FPA) risk introducing in-band and out-of-band spurious response, or aliasing, due to undersampling. This can make high-level discrimination tasks such as recognition and identification much more difficult. To overcome this problem, three-chip color charge coupled device (CCD) cameras typically offset one CCD by 1/2 pixel with respect to the other two. Analogously, monochrome imagers including infrared can use microscan (or dither) to reduce aliasing. This...
Local School District Procedures. School districts are encouraged to develop local problem resolution procedures that allow parents to present a concern to a district representative and receive a response related to the concern. Local procedures shall not be used to delay or deny a parent's right to access other dispute resolution mechanisms.
What is the Department of Elementary and Secondary Education's Problem Resolution System? The Problem Resolution System is the Department's process for receiving, reviewing and resolving concerns from the public regarding students who allegedly are not receiving educational services, students with disabilities who allegedly are not receiving access to the general curriculum (i.e., the curriculum expected to be taught to all students), or students who allegedly are not receiving procedural protections that by law must be provided. The System is staffed by Educational Specialists who respond to questions regarding education laws, regulations, or policies and refer questions to other knowledgeable persons where necessary.
