1. IMPACTS OF EVIDENCE ON DECISION-MAKING IN POLICE INVESTIGATION
Sammanfattning : When conducting an investigation, police officers collect evidence from various sources (e.g., humans, objects, areas). The type of evidence (i. LÄS MER
2. Eco-evolutionary processes and community patterns--- novel avenues for studying biodiversity across spatial and temporal scales
Sammanfattning : Understanding biodiversity patterns poses a persistent challenge due to the complex interconnections of ecological and evolutionary processes. The particular difficulty comes from the various processes influencing biodiversity patterns across different spatial scales. LÄS MER
3. Novel tantalate-niobate films for microwaves
Sammanfattning : Microwave materials have been widely used in a variety of applications ranging from communication devices to military satellite services, and the study of materials properties at microwave frequencies and the development of functional microwave materials have always been among the most active areas in solid-state physics, materials science, and electrical and electronic engineering. In recent years, the increasing requirements for the development of high speed, high frequency circuits and systems require complete understanding of the properties of materials function at microwave frequencies.

4. Simulation and Electrical Evaluation of 4H-SiC Junction Field Effect Transistors and Junction Barrier Schottky Diodes with Buried Grids
Sammanfattning : Silicon carbide (SiC) has higher breakdown field strength than silicon (Si), which enables thinner and more highly doped drift layers compared to Si. Consequently, the power losses can be reduced compared to Si-based power conversion systems. Moreover, SiC allows the power conversion systems to operate at high temperatures up to 250 oC. LÄS MER
