این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسله­‌مراتبی جهت پیگیری فرایند توسعه تأمین‌کنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه‌ می‌کند. ابتدا، زمینه‌های تأمین نیازمند سپس واجد شرایط هریک زمینه‌ها به کمک تصمیم‌گیری چندشاخصه بهترین-بدترین مشخص می‌گردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهره‌گیری نظرات خبرگان حوزه‌ی خرید استخراج‌شده‌اند. درنهایت، مدل ریاضی ...

A key problem in ion-solid interaction is the lack of experimental access to dynamics processes. While it clear that mechanisms and sputtering depend on kinetic potential energy (sum ionization energies) projectile, importance interplay various are unknown. Here, we have irradiated substrate-supported (Au, ${\mathrm{SiO}}_{2}$) monolayers ${\mathrm{MoS}}_{\text{2}}$ with highly charged xenon io...

Slow highly charged ions (HCIs) carry a large amount of potential energy that can be dissipated within femtoseconds upon interaction with a surface. HCI-insulator collisions result in high sputter yields and surface nanofeature creation due to strong coupling between the solid's electronic system and lattice. For HCIs interacting with Al oxide, combined experiments and theory indicate that defe...

When interacting with technical systems, users experience mental workload. Particularly in multitasking scenarios (e.g., interacting with the car navigation system while driving) it is desired to not distract the users from their primary task. For such purposes, human-machine interfaces (HCIs) are desirable which continuously monitor the users' workload and dynamically adapt the behavior of the...

In Greece, the use of information systems in the public health sector is limited (Theodorakioglou and Tsiotras 2000). The Greek National Health Service has initiated reforms towards decentralization of health care services and development of integrated HCIS at a regional level. However, a large number of these plans have not been implemented. This paper addresses an initiative of the Foundation...

Highly charged ions (HCIs) are promising candidates for the next generation of atomic clocks, owing to their tightly bound electron cloud, which significantly suppresses common environmental disturbances quantum oscillator. Here we propose and pursue an experimental strategy that, while focusing on various HCIs a single element, keeps number candidate clock transitions as large possible. Follow...

Growing use of computers in safety-critical systems increases the need for Human Computer Interfaces (HCIs) to be both smarter to detect human errors and better designed to reduce likelihood of errors. We are developing methods for determining the likelihood of operator errors which combine current theory on the psychological causes of human errors with formal methods for modelling human-comput...
