We use the concept of boundary object to analyse the technological activities. The amorphousness of leisure‐time technology – the fact that children can choose what they want it to be and what to learn –points to it being a boundary object with a very open interpretative ana masters of marketing 2016 flexibility. The driving behaviour of the driver involves multiple interactions (Björklund & Åberg, 2005) that create a specific focus in safety study. Some literature related to the behaviour of driving interacting with pedestrians was given in Chapter 2.
System level I/O operations in Node are handled by libuv which does use a background thread pool. The difference is, the main thread can fire and forget the task to a background thread and the background thread will notify the main thread when the operation is completed. Even with background thread processing, doing lots of I/O operations doesn’t scale very well.
Road segments using traffic markings to separate the vehicle lane and the adjacent bicycle lane are widely adopted on urban roads. Bicycles’ illegal lane-changing behavior is commonly observed on such road segments, resulting in severe influences of traffic efficiency and bringing hidden dangers. However, existing models disregard different categories of ILC and heterogeneities of ILC between electric bikes (e-bikes) and regular bikes (r-bikes), which has limitations in representing the realistic ILC.
Different demographic segments of the population will accept and respond to marketing in varying ways, times, and frequencies. One factor that will also impact the price of your products or services is supply and demand; how many units of your product exist and how many people actually want it? Supply can either be infinite, like a digital software product or limited and exclusive, like a Tesla car, for example. Price can connote different characteristics of products; a high price tag, in some cases, can imply luxury and exclusivity, but this is largely dependent on the brand’s reputation and promotional styles such as advertising and tone of voice. This will have a negative impact if your goods do not live up to the price paid for them, if they’re made poorly or break quickly, for example.
Borgonovo et al. suggested that smart parking systems are set to bring positive changes to different urban stakeholders, who, in one way or another, shoulder the burden of haphazardly managed parking spaces. For instance, it is believed that these systems will have a positive impact on traffic accident rates, i.e., crashes resulting from driver attention deficits as they concentrate on searching for parking spaces or rush to occupy existing ones . A decline in accidents will coincide with speed and efficiency in locating vacant spaces by drivers via smartphone apps; hence, drivers will no longer need to scramble for spaces . For instance, Sajeev et al. noted that the use of a smart system would allow managers to set parking fees commensurate to the facility’s current occupancy. Therefore, these parking systems will have both financial and logistical merits for owners, political leaders, and urban managers. The Internet of Things has come of age, and complex solutions can now be implemented seamlessly within urban governance and management frameworks and processes.
Challenges and benefits in the ITS have motivated researchers to introduce and promote the vehicular cloud computing . The VCC is a new technology, which takes advantage of the cloud computing to offer better services and improve the driving experience of VANET drivers. It aims to provide the services to the drivers, improve traffic flow, reduce traffic congestion, accident, and ensure the usage of real-time software and infrastructure with the QoS . Specifically, the VCC can be the platform for the convergence of ITS and computing and storage capabilities of the MCC. Moreover, the VCC can incorporate the features of ITS, WSN, and MCC for providing better road safety, improving driving conditions, and securing traffic management systems . The self-driving vehicles and advanced assistance application used for highly automated driving will depend on the V2X communication technology, which are empowered by fog and edge computations .
Specific elements are labelled, and section numbers given for where detailed assessment information can be found. Innovative tools and practices in polar resource management and planning show strong potential in improving society’s capacity to respond to climate change . Shipping activity during the Arctic summer increased over the past two decades in regions for which there is information, concurrent with reductions in sea ice extent . The Southern Ocean that surrounds Antarctica is the main region globally where waters at depth rise to the surface. Here, they become transformed into cold, dense waters that sink back to the deep ocean, storing significant amounts of human-produced heat and dissolved carbon for decades to centuries or longer, and helping to slow the rate of global warming in the atmosphere. Future changes in the strength of this ocean circulation can so far only be projected with limited certainty.
Every vehicle needs to be registered with CA database before it officially joins the VANET system; the vehicle can communicate with CA in two ways either directly as an offline registration or via RSU as an online registration by indirect way. Raya and Hubaux introduced a new method which utilizes the anonymous public keys to provide privacy. The main demerits are it required a large amount of storage and memory and also requires huge amount of certificate revocation list checks, since using large amount of anonymous keys. Therefore, it may be the reason for DOS attack due to large amount of computational overhead. Meanwhile, aggregating vehicles into platoons could reduce the computation burden, making it more practical to be implemented in the real world. However, the method may only generate sub-optimal strategies due to this simplification.
The capacity, density, and features are the primary differences driving platform selection. Both lead platforms have sibling platforms that may be appropriate for the core role in existing networks or networks where the full capabilities of the lead platforms are not required. The optical transceiver modules which connect the distribution layer switches to the core layer switch platforms have to interoperate with each other and have to be compatible with the fiber optic cabling between buildings. It is recommended to implement queuing on switches, where oversubscription of ports can result in transient congestion, which can cause packet loss.
