bicycle riding is one of the attractions in kish island that is known as an entertainment and enjoyable sport. moreover, it is beneficial to the environmental goals and tourism industry. for this aim, the bicycle rental system is provided by nineteen bicycle stations that have been distributed all around the island by kish free zone organization; also, to spread the bike riding culture and incr...

Several interesting monitoring applications concern people entering a prescribed area, where they deposit an object in their possession, or collect an object deposited earlier. One example arises in the use of bicycle racks. We propose a novel method for associating each person who deposits an object with the person who later collects it. Our main contribution is to deal with ambiguity in the v...

Split-hom together structure is a new heavy load rack structure, and its reliability needs to be verified. Through analyzing multimodal hom-connection principle from the perspective of bionics and contact mechanics, the article puts forward three kinds of hom-connection methods and establishes the finite element model and mathematical model of the rack. Afterwards, the finite element model and ...

Automatic activity recognition is the computational process of analysing visual input and reasoning about detections to understand the performed events. In all but the simplest scenarios, an activity involves multiple interleaved events, some related and others independent. The activity in a car park or at a playground would typically include many events. This research assumes the possible even...

Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate and improve the system throughput. The free-fall-flow-rack AS/RS has emerged as a new technology for dr...

3D scanning, printing, and CAD design software are considered important tools in Industry 4.0 product development processes. Each one of them has seen widespread use a variety scientific commercial fields. This work aims to depict the added value their combined proposed workflow where customized needs be developed. More specifically, geometry an existing physical item’s defined order fabricate ...

conclusions higher age of cyclists and increasing speed of the accident opponent significantly increase the likelihood of sustaining facial fractures. the use of bicycle helmets does not significantly reduce the incidence of mid-facial fractures, while being correlated with an even increased incidence of mandibular fractures. background the effectiveness of bicycle safety helmets in preventing ...

The designer proceeds with his work by collecting and combining knowledge about the design object; in so doing, the knowledge possessed by the designer is organized and extended. In cooperative design performed by multiple persons, this organized knowledge is shared among them. This study proposes a designer support environment in which design knowledge is organized by using conceptual systems ...
