Ricci solitons (RS) have an extensive background in modern physics and are extensively used cosmology general relativity. The focus of this work is to investigate almost (RAS) on Lorentzian manifolds with a special metric connection called semi-symmetric u-connection (SSM-connection). First, we show that any quasi-Einstein manifold having SSM-connection, whose RS, Einstein manifold. A similar c...

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 ...

UNLABELLED SiGN-SSM is an open-source gene network estimation software able to run in parallel on PCs and massively parallel supercomputers. The software estimates a state space model (SSM), that is a statistical dynamic model suitable for analyzing short time and/or replicated time series gene expression profiles. SiGN-SSM implements a novel parameter constraint effective to stabilize the esti...

The first products derived over France in 2010 from the L-band brightness temperatures (Tb) measured by the SMOS (Soil Moisture and Ocean Salinity) satellite, launched in November 2009, were compared with the surface soil moisture (SSM) estimates produced by the C-band Advanced Scatterometer, ASCAT, launched in 2006 on board METOP-A. SMOS and ASCAT SSM products were compared with the simulation...

This paper describes research into utilising a Group Support System (GSS) to enable the use of the Soft Systems Methodology (SSM) in distributed situations, which prohibit face-to-face application of SSM. The design goals, issues, major decisions, and initial pilot evaluation of a prototype GSS for SSM are described. 46 subjects and 2 facilitators participated in an experimental application to ...

Participative design is an effective tool for designing organizational systems where conflicting and diverse goals of users and clients from different organizations must be reconciled. This paper presents a methodology for participative design based on Soft Systems Methodology (SSM). A brief overview of SSM is first presented. The design methodology is then presented within the SSM framework. T...

1 Sex Differences in Accompaniment and Technology Usage in a Coffee Shop Margaret Diamond, Chloe Kingery, Jessica McAbee, and Jessica Thompson, Department of Psychology Gender differences in accompaniment and technology use were observe in a coffee shop close to a college campus. Young adults (N=232) were observed to see if there was a difference in having accompaniment or sitting along. They w...

SSM is a socio-technical system methodology offering tools for analysing complex situations. This modelling approach identifies differing worldviews of the system by encouraging discussion and debate. Academic ethical studies of moral philosophy have been extensively studied but rarely attributed to system modelling. We investigate the possibility of an ethical dimension to SSM comparing it to ...
