Smart grid (SG) has become a hot research topic with the development of new technologies, such as IoT, edge computing, artificial intelligence, big data, 5G, and so on. The efficiency of SG will be increased by smart embedded devices that have intelligent decision-making ability. Various types of sensors and data sources will collect data of high resolution. One of the vital challenges for IoT is to manage a large amount of data produced by sensors. Sending this massive amount of data directly to the cloud will create problems of latency, security, privacy, and high bandwidth utilization. This issue is addressed by edge computing (EC). In EC, the data are processed at the edge of the network that is near the embedded gadgets. This paper provides a comprehensive review of the smart grid systems, based on IoT and EC. The development in the rising technologies, the framework for EC-...

It is an excellent platform for addressing topics in long-term evolution and paleobiology, such as mass extinction and recovery, with experimental evolutionary approaches. We evolved model communities with ecological interdependence among community members, which were subjected to two principal types of mass extinction: a pulse extinction that killed randomly, and a selective press extinction involving an alteration of the abiotic environment to which the communities had to adapt. These treatments were applied at two different strengths, along with unperturbed control experiments. We examined how stability in the digital communities was affected from the perspectives of division of labor, relative shift in rank abundance, and genealogical connectedness of the community's component ecotypes. Mass extinction that was due to a Str...

Linguistics, has defined context as the passage, sentence or text in which the word appears that is used for ascertaining its meaning. Thus, context is dependent on the POS (Part Of Speech) where the word is used e.g. Adverb, Adjective, Pronoun, Verb and Noun. In the following study we recommend a unique way of WSD based on Context through WordNet, multimodal algorithm that is knowledge based, map-reduce and soft sense WSD.

Researchers are trying to incorporate multimodal information retrieval using machine learning, support vector machines, neural network and neuroscience etc. to provide an efficient retrieval system that fulfills user need. This paper is an overview of multimodal information retrieval, challenges in the progress of multimodal information retrieval.

The vehicle-to-vehicle communication system (V2V) is one of the solutions to decrease the accident ratios. The existing V2Vs are fixed based on single radio and are inefficient and unreliable especially in the hilly areas due to low SNR and partial coverage. Their performance is degraded in the metropolitans due to dense population and over-burdened traffic routes. Keeping above disadvantages in mind, multiradio access technologies (GSM/GPRS, CDMA, Wi-Fi) based V2V using cognitive radio framework is proposed in this paper. The method introduces an in-vehicle cognitive radio site with the capabilities of spectrum sensing, spectrum decision and spectrum mobility. Experimental results demonstrate that the proposed solution does not overburden the existing networks in affected area and vehicles remain aware of other vehicles even in low SNR by single radio technology and partial coverage areas.

Femtocells, however, use the IP Network as backhaul architecture instead of the conventional cellular network infrastructure. Thus, femtocell and WiFi infrastructure networks have a lot in common. This raises a curiosity whether femtocell technology would replace existing WiFi technology. This can be answered only by carefully analyzing the similarities and differences between the two technologies. This paper provides a technical comparison between femtocells and WiFi in terms of architecture, operation and standards.

In this study we investigate the comparative behavior of four load balancing algorithms when the number of processors is dynamically changed during the lifetime of a multistage parallel computation. The focus is on communication and data movement overheads, total parallel runtime and total resource consumption. We demonstrate the main ideas for the case of six adaptive mesh refinement (AMR) applications with different kinds of growth patterns. The results presented are for a 32 processor Intel cluster connected by Ethernet.

The main concept of the 802.11-based vehicular communications involves encountering the already deployed WLAN access points from the vehicles and using the same for communication purposes. Different works in literature have evaluated the performance of such a challenging scenario from different perspectives, however, very little has been done in modelling this unique kind of communication. In this paper, we show that the previously used models are not applicable in 802.11-based R2V scenario and give a hidden Markov model representation of the same. We evaluate the model parameters based on the data collected from the drive tests. This is a relatively new research direction that has not been rigorously explored before.
