in this paper, we introduce fractional order of a planar fractional prey-predator system with a nonmonotonic functional response and anti-predator behaviour such that the adult preys can attack vulnerable predators. we analyze the existence and stability of all possibleequilibria. numerical simulations reveal that anti-predator behaviour notonly makes the coexistence of the prey and predator po...

To incorporate metabolic, bioremedial functions into the performance of buildings and to balance generative architecture's dominant focus on computational programming and digital fabrication, this text first discusses hybridizing Maturana and Varela's biological theory of autopoiesis with Andy Clark's hypothesis of extended cognition. Doing so establishes a procedural protocol to research biolo...

The paper looks at tag-based cooperation within abstract simulation models. Previous models of this kind have been shown to either have ‘programmed in’ cooperation or to be vulnerable to “strong cheaters”. Previous work by the author included a model of social specialisation and cooperation, but where only a single dominant tag-group arose at any one time and where cooperation eventually collap...

iran is located in a high-risk seismic zone of earthquakes. it has thousands of valuable historic buildings, mostly made of unreinforced masonry, which is quite vulnerable to natural hazards, especially earthquakes. the conservation and seismic upgrading of these buildings is vital for their survival. however, resources are limited and some sort of prioritization is needed in order to allocate ...

In the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. This lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. In this paper, a “service-life factor” has been defined. Applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

Touching of contaminated objects and surfaces is a well-known method of virus transmission. Once they are attached to the hands, viruses can easily get adsorbed and initiate infection. Hence, disinfection of frequently touched surfaces is of major importance to prevent virus spreading. Here we studied the antiviral activity of a glucoprotamin-containing disinfectant against influenza A virus an...

The Radio Frequency Identification (RFID) system plays an important role in authentication, security control, supply chain management, and inventory control. Due to market consideration, low-cost RFID systems have become very popular in recent years. In many applications, such as e-passport, RFID systems need security mechanisms to resist all possible attacks and security risks. However, becaus...
