Will you accept my Job? A New Approach Towards Predicting Human Participation in Mobile Crowdsensing
by Tanveer Ahmed, Abhishek Srivasta
Abstract: In the last decade, the exponential growth of wireless devices have paved the
way for several newand innovative mobile oriented paradigms. One such area that
has started to receive attention in literature is mobile crowdsensing. Composed
of ordinary people and their personal devices, the paradigm promises several
astonishing developments that compel us to imagine a much smarter future.
However, before we get to explore such a lucrative prospect, we need to focus our
efforts on important issues that remain unaddressed. One specific aspect that has
been repeatedly ignored in literature is the factor concerning human participation.
This is because work has primarily focused on the technical capabilities of a
mobile device, and has often neglected the issue of human participation. In
this paper, therefore, we aim to address this shortcoming. We present a novel
probabilistic approach to predict whether we can expect a response from the
crowd or not. The proposed candidate selection algorithm takes its inspiration
from statistics and handles the typical uncertainties in human behavior.Validation
of the proposed framework is done in two ways. 1)We implement a prototype and
deploy it over a cloud based Enterprise Service Bus, MuleESB. 2) We perform
numerical testing on real datasets. With this experimental testbed, we will show
the efficacy of the framework in realistic and actual deployment scenarios.

Simulation analysis of the search effectiveness on information-based firefighting
by Lin Hui
Abstract: Nowadays, fire accident is still a thorny problem due to the current firefighting still heavily relies on the experience instead of information. Saving lives from fireground is the primary task in firefighting, in which the speed of effective search largely relies on the sufficient and instant information. When insufficient information situation follows firefighter tightly, the firefighters life can be jeopardized. Equipped firefighter with the advancing information technology, such as IR, laser range-finder, camera, augmented reality and an unmanned aerial vehicle for acquiring more fireground information may be useful for firefighting task. This study focuses on using Monte Carlo simulation model to quantify the feasible alternatives and finds out the significant effect by t-test. The result showed the time in search of victim is significantly reduced as using new way of firefighting. The contribution of this paper is to disclose the value of the proposed information-based technology in support of firefighting.

Combined forecasting model of urban water consumption based on adaptive filtering and BP neural network
by Ban Fuchen, Wu Dan, Hei Yueming
Abstract: In order to solve the problem of improving the precision of urban short-term water consumption forecasting, the idea of combination forecasting is put forward. According to the water use data of a city, the time series prediction method and the explanatory prediction method are used to forecast the water use in the short term. In order to combine the advantages of the two forecasting methods, this paper proposes a combination forecasting method based on weight coefficient optimization theory. Compared with the single prediction model, the combined forecasting model has higher accuracy and stability.

Link Stable Routing with Minimal Delay Nodes for MANETS
by Jayalakshmi P, Saravanan R
Abstract: Multi-hop routing in MANETs requires good resource managing protocols. The efficient route from source to destination in the network is identified by determining the level of signal strength from intermediate hops. The link quality between the intermediate nodes is determined by calculating the signal strength level. The received signal strength is one method to estimate the medium characteristics and distance between the intermediate nodes which is one of the quality of service required by the network. The nodes with high signal strength and high bandwidth are identified as minimal delay nodes so as to determine the reliable path. The data is sent through minimal delay nodes in the shortest path from source to destination. The better link quality improves the performance metrics such as packet delivery ratio, throughput and simultaneously reduces the control message overheads, average and end-to-end delay compared to some of the existing routing protocols. The experimental study shows that the proposed routing protocol is 30% better in packet delivery ratio, throughput, reduced control message overheads, average and end-to-end delay than the existing Stable and Delay Constrained Routing protocol.
Keywords: Routing; Minimal delay nodes; Signal strength; MANET.rnrn.
A Simultaneous Evolution for Analyzing the Interactions between CO2 emissions and national income
by Cheng-Min Chuang, Chih-Chuan Yeh
Abstract: In this paper, we estimate the causal interrelationships between growth and CO2 emissions within a simultaneous equations framework and obtain identification using a novel heteroskedasticity-based method. After the removal of the bias, we find that per capita GDP and CO2 emissions are strongly interrelated. Moreover, we split our dataset into high-income, middle-upper-income and low-income countries, and the results indicate that the beneficial effect of per capita GDP on CO2 emissions in high-income panel countries is greater than that in middle-upper panel countries. However, quicker economic development induces higher pollution in low-income countries. On the other hand, the effect of CO2 emissions results in the improvement of per capita GDP for the low to middle-upper income panel but a decrease in the improvement of per capita GDP for the high-income countries.
Keywords: Economic growth; CO2 emissions; Simultaneous equations; Endogeneity bias.
Understanding Blogging Motivations in Palliative Care Using Maslows Hierarchy of Needs
by Nothando Ngwenya
Abstract: The pervasive use and potential of weblogs has increased the field of social health informatics and is becoming increasingly difficult to ignore. The prevalence of these technologies for narrative use brings about the fusion of diverse schools of thought on motivation. One proven model is that of Maslow, whose theory of needs has an intuitive appeal in understanding bloggers needs and motivations. This paper considers theoretical and practical blogging experiences for palliative care users through the theoretical lens of Maslows hierarchy of needs. Palliative care patients, carers and clinicians were interviewed about their weblogs and data qualitatively analysed. The results indicate that the experience of maintaining a weblog is therapeutic for individuals and fulfils needs hierarchically from the lowest to the highest as outlined in Maslows theory.
Keywords: Weblogs; Maslow's hierarchy of needs; CyberPsychology;End of life; Motivation; Computer Mediated Communication.
Exploring Taiwanese smartphone user intention: An integrated model of Technology Acceptance Model and Information System Successful Model
by Ching-Hsue Cheng, Chung-Hsi Chen, You-Shyang Chen, Ho-Long Guo
Abstract: The study is focused on behavioral intentions of smartphone users, and theses are based on information system success model (ISSM) and technology acceptance model. In this study, we use SEM to examine the model that includes dimensions and relevant variables. The dimensions of model include information quality, system quality, service quality, perceived ease of use, perceived usefulness, attitude and behavioral intentions. The results indicate that there are no differences between perceived usefulness and information quality, system quality, and there is also no difference between perceived ease of use and behavioral intentions. In addition to above hypotheses the other are all supported among these hypotheses. We found the most indirect variable affect the behavioral intentions is system quality. This means that system quality is the most important factor to affect smartphone system. We also found that perceived ease of use is very important for smartphone users, and if the smartphone systems are not easy to use, they would not be accepted by people.
Keywords: Smartphone; Information system success model (ISSM); Technology acceptance model (TAM); Behavioral intention (BI).
Causal relation extraction and network construction of web events
by Qichen Ma
Abstract: The explosive increase of news data on the web has created a mass of causal knowledge, which explains the causal relation between two events that effect event will occur following the occurrence of cause event. Analysis of causal knowledge has gain lots of attentions due to its widespread applications, such as question answering, event prediction, generating future scenarios, and commonsense causal reasoning. However, few work analyzes the causal knowledge in a particular domain. Therefore, we extract causal relation and build network of causal events in food domain. First, we propose a method to obtain complete cue phrases and present four common causal patterns to extract causal relations. And then we merge the same events by similarity calculation of causal events. At last, a network of causal events is constructed. Experiments on the datasets show the effectiveness of the proposed approach.
Keywords: causality knowledge; causal relation extraction; causality network.
Context-Sensitive Smart Devices Definition and a Functional Taxonomy
by Ramnath Krishnan Pallasena, Mayank Sharma, Venkataraghavan Krishnaswamy
Abstract: Smart devices are no longer fashionable artifacts but have found mainstream adoption. Smart devices help humans by being context-sensitive, run errands or execute tasks and support their daily operations. This paper defines these context-sensitive smart devices (CSSD). We review the context and context sensitivity exhibited by mobile phones and smart devices. We further discuss the functionality of these smart devices and provide a functional taxonomy classification. This functional taxonomy could act as a framework in the design and development of CSSD. We illustrate the application of the functional taxonomy in different contexts, bringing out the characteristics, challenges, and applications in each context.
Keywords: Smart devices; Context-aware systems; Context-sensitivity; Taxonomy classification.
