This paper addresses Test Application Time (TAT) reduction for core-based 3D Stacked ICs (SICs). Applying traditional test scheduling methods used for non-stacked chip testing where the same test schedule is applied both at wafer test and at final test to SICs, leads to unnecessarily high TAT. This is because the final test of 3D-SICs includes the testing of all the stacked chips. A key challenge
Forestry has been one of the major industries in the Swedish economy since the middle of the nineteenth century. During the second part of the twentieth century the industry went through powerful technological changes. Traditional handicraft methods were replaced by modern high technology. As for the forestry VET this meant a strong expansion during the 1950s and 1960s followed by integration into
Moving forward, higher education will face a variety of challenges, especially in 2020/2030, due to technological development and digitalization. Digitalization in society has grown, and society fosters digital citizenship to a greater extent. Students entering higher education today have grown up with the Internet and mobile devices. Daily life, schools, and work have also become more mobile beca
Popular Abstract in Swedish Användandet av mer än en antenn för både sändare och mottagare i radiokommunikation kommer att spela en viktig roll för att uppnå den önskade dataöverföringshastigheten på upp till 1 gigabit per sekund i nästa generations kommunikationssystem. Detta eftersom tekniken, känd som multiple-input multiple-output (MIMO), ger en dataöverföringshastigheten som är proportionerliThe use of multi-antenna systems with multiple-input multiple-output (MIMO) technology will play a key role in providing high spectrum efficiency for next generation mobile communication systems. This thesis offers valuable insights on the design of compact multi-antennas for efficient MIMO communications. In the course of the thesis work, several novel six-port antenna designs have been proposed
