Synthetic aperture radar provides high-resolution images of the non-moving ground scene, but fails to indicate and position moving objects. A short review of the motioninduced effects occurring in SAR images will open this lecture. Like in special airborne MTI systems, the solution to the SAR MTI problem is to use an array of antennas or subapertures and several receiving channels to cancel the...

In most digital communication systems, the information bits to be transmitted are protected against transmission errors. Typically, in the transmitter redundancy is added in a clever way by means of an encoder. In the receiver, a corresponding decoder is able to detect or to correct transmission errors by exploiting the redundancy. This technique is called channel coding. Applications of channe...

Percutaneous transluminal coronary angioplasty (PTCA) or balloon angioplasty, was performed in the United States, but the technique remained challenged by the primary problem of ''re-stenosis'', which was approximately 30% closing of the coronary artery after balloon dilatation. When first PTCA introduced by Gruentzig in 1977, it was specific directed for patients who have angina, documented is...

Introduction: Radiotherapy with heavy charged particles such as protons and carbon ions (hadron therapy) has been recognized as an advanced technique for the treatment of various cancers. For some indications such as pediatric and radio-resistant tumors, it is considered the preferred method. However, despite its remarkable benefits, development of hadron therapy centers in the...

Abstract Introduction Indication documentation is one part of the prescribing process that can aid safer practice with a positive impact on patient, prescriber, and wider healthcare team (1,2). Despite recommendations, indication prescriptions inpatient medication orders not routinely practiced. Literature describing interventions aimed at improving scarce. Aim We to provide: (1) an overview ex...
