•Survey on the practice of big data analysis in agriculture.•Detailed review of 34 high-impact relevant research studies.•Discussion on the status and potential of big data analysis in ...agriculture.•Open problems and challenges, barriers for wider adoption and use.•Ways to overcome barriers and potential future applications in agriculture.
To tackle the increasing challenges of agricultural production, the complex agricultural ecosystems need to be better understood. This can happen by means of modern digital technologies that monitor continuously the physical environment, producing large quantities of data in an unprecedented pace. The analysis of this (big) data would enable farmers and companies to extract value from it, improving their productivity. Although big data analysis is leading to advances in various industries, it has not yet been widely applied in agriculture. The objective of this paper is to perform a review on current studies and research works in agriculture which employ the recent practice of big data analysis, in order to solve various relevant problems. Thirty-four different studies are presented, examining the problem they address, the proposed solution, tools, algorithms and data used, nature and dimensions of big data employed, scale of use as well as overall impact. Concluding, our review highlights the large opportunities of big data analysis in agriculture towards smarter farming, showing that the availability of hardware and software, techniques and methods for big data analysis, as well as the increasing openness of big data sources, shall encourage more academic research, public sector initiatives and business ventures in the agricultural sector. This practice is still at an early development stage and many barriers need to be overcome.
•Smartphone-based NIR was used to estimate salted meat composition.•Accuracy of fat and moisture estimates are acceptable for quality control purposes.•Predictive ability of smartphone-based NIR is ...similar to a benchtop spectrometer.•Random Forest Predictive models are robust at temperatures from −14 °C to 25 °C.
This research work evaluates the feasibility of a smartphone-based spectrometer (740–1070 nm) for salted minced meat composition diagnostics at industrial scale. A commercially available smartphone-based spectrometer and a benchtop NIR spectrometer (940–1700 nm) were used for acquiring 1312 spectra from meat samples stored at four different temperatures ranging from −14 °C to 25 °C. Thereafter, for each spectrometer, PLS and Random Forest regression models specific for each temperature and global models were created to predict the fat, moisture and protein contents. Fat and moisture can be estimated with the global model in a wide range of temperatures by using the smartphone-based spectrometer, which has an acceptable accuracy for quality control purposes (RPD > 7) and comparable to the accuracy of a benchtop spectrometer.
A novel spectral analysis technique of OCT images is demonstrated in this paper for classification and scatterer size estimation. It is based on SOCT autoregressive spectral estimation techniques and ...statistical analysis. Two different statistical analysis methods were applied to OCT images acquired from tissue phantoms, the first method required prior information on the sample for variance analysis of the spectral content. The second method used k-means clustering without prior information for the sample. The results are very encouraging and indicate that the spectral content of OCT signals can be used to estimate scatterer size and to classify dissimilar areas in phantoms and tissues with sensitivity and specificity of more than 90%.
In this paper we present VITAL-5G platform, a flexible 5G innovative infrastructure that can host Network Applications (NetApps) to optimize the performance and the efficiency of services in the ...Transport & Logistics (T&L) sector. It is a complete system that comprises hardware, software, and 5G connectivity components that will be implemented in three different trial sites: (i) Antwerp port, (ii) Galati port and (iii) Athens Diakinisis logistics hub. A variety of 5G-enabled NetApps from the VITAL-5G consortium partners, as well as third party experimenters, will be developed to address specific T&L industry challenges. The experimentation services offered by the VITAL-5G facility will allow the third parties to early test and experimentally validate the new features and enhanced performances enabled by the adoption of the 5G technology in their applications and services.
Purpose - The purpose of this paper is to provide a better understanding of how the internet is used as a strategic tool in electronic customer relationship management (e-CRM) in the football sector. ...In particular, the research questions this paper addresses are: How can the online environment be described? How are the customers served in this online environment? The first research question provides an overview of the online environment and the second research question describes the services offered in this online environment.Design methodology approach - The qualitative research is the appropriate approach, in order to collect the required data, as the particular research characterizes a complete and comprehensive view and understanding of a phenomenon in its entity. The research is based on the use of double case study approach combining two data collection methods, participant observation and documentation. This particular research adopts the approach of participant observation and documentation. Primary data are collected through an observation checklist, with the help of browse target web sites related to the study. In order to get additional information about the clubs' specific data, the paper used e-mails. Secondary data were collected through documents from different sources to verify the collected data. In documentation are used official publications, newspapers, journals, and brochures.Findings - The study indicates that the design of a web site needs to be viewed primarily as a business task, which is consistent with previous research, not a technical task. The web site design needs to be appropriate to the needs of the club and should focus supporting business goals. Managers need to increase web site self-problem solving functions. It helps to decrease customer's interactivity with company's representatives. The contents match with the theory mostly. They are match efficient in providing online services but they still need to provide complete shipping information. This study contributes to previous theory since it has investigated the use of the internet in customer relationship management (CRM). However, due to the lack of research concerning the e-CRM in the football sector this study needs further consideration by collecting data through interviews with CRM managers and fans. Finally, the same study can be conducted on a larger sample of web sites.Originality value - CRM and internet as strategic tools in the football sector is a new research area and not covered adequately in recent and past publications in recognized international journals.
