Shape is one of the most important features in Content Based Image Retrieval (CBIR). Many shape representations and retrieval methods exists. However, most of those methods either do not well represent shape or are difficult to do normalization (making matching hard). Among them, methods based Fourier descriptors (FD) achieve both well representation and well normalization. Different shape sign...

Based on previous research on finger based representation of numbers, we investigated the relation between sequential finger tapping and numeric working memory. Subjects (N=44, all right handed) were given a sequential finger tapping (SFT) test and a forward and backward digit-span (FDS, BDS) test. SFT test measured the participants’ ability to execute simple (following the anatomical order) an...

The present study compares prosodic features of child-directed speech (CDS) and foreigner-directed speech (FDS), to examine whether FDS is a derivative of CDS as suggested in sociolinguistic studies. Twelve female speakers completed a simple referential communication task addressed to an imaginary adult, an imaginary foreigner, and an imaginary child. The results showed that, compared to the ad...

Background. A panel of experts (the 2014 Panel) convened by the American Dental Association Council on Scientific Affairs developed an evidence-based clinical practice guideline (CPG) on the use of prophylactic antibiotics in patients with prosthetic joints who are undergoing dental procedures. This CPG is intended to clarify the “Prevention of Orthopaedic Implant Infection in Patients Undergoi...

Most search engines return a lot of unwanted information. A more thorough filtering process can be performed on this information to sort out the relevant documents. A new method called Frequency Domain Scoring (FDS), which is based on the Fourier Transform is proposed. FDS performs the filtering by examining the locality of the keywords throughout the documents. This is examined and compared to...

Two dimensional fluorescence difference spectroscopy (2D FDS) detects nanoparticle interactions following surface functionalization and biomolecule loading by generating a spectral signature of the fluorescent intensity per excitation and emission wavelengths. Comparing metal oxide nanoparticles revealed a unique spectral signature per material composition. 2D FDS showed to be sensitive to chan...

در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بار‌های تولید طراحی شده است. اهداف اصلی مدل، کمینه‌سازی هزینه‌‌های کل و حداکثر استفاده از منابع به‌منظور عادلانه شرایط عدم­قطعیت کنترل پارامتر‌های غیرقطعی روش برنامه‌ریزی فازی ‌شده نتایج نشان می‌دهد افزایش نرخ عدم‌قطعیت، می­یابد. ازآنجاکه ظرفیت کارخانه‌ها ثابت است، مقدار تقاضا، هر کارخانه نیز می­ی...

We calculate the ratio fBs/fBd by following the Oakes’ method which is based on chiral symmetry breaking, but we improve his calculation by performing the calculation of the factor < 0|b̄γ5s|Bs >/< 0|b̄γ5d|Bd > in the mock meson model. In this calculation we improved the mock meson model by using the value of the parameter β which is obtained by the variational method in the relativistic quark mo...

In this paper, the use of Fire Dynamics Simulator (FDS) and its evacuation module, Evac for modelling fire and people evacuation in a road tunnel is illustrated. For given fire scenario and traffic situation in the tunnel, behaviour of individual evacuees as well as groups of evacuees is analyzed in order to demonstrate the impact of fire on people evacuation. Some specific features of the use ...

In this paper, simulation of fire in a short 2-lane road tunnel and its evacuation are described. Two traffic situations in the tunnel and their impact on people evacuation in fire conditions are analyzed. For simulation of the tunnel fire, the FDS (Fire Dynamics Simulator) system, version 5.5.3 based on advanced CFD (Computational Fluid Dynamics) fire model is used. The evacuation of people in...
