Combining Fog and Cloud Computing to Support Spatial Analytics in Smart Cities

Spatial data generated by an Internet of Things (IoT) network is important to assist the spatial analytics process in issues related to smart cities. In these cities, IoT devices generate spatial data constantly. Thus, data can get increasingly voluminous very fast. In this paper, we investigate the challenge of managing these data through the use of a spatial data warehouse designed over a parallel and distributed data processing framework extended with a spatial analytics system. We propose an architecture aimed to assist a smart cities manager in the decision-making process. This architecture integrates a cloud layer where these technologies are located with a fog computing layer for extracting, transforming and loading the data into the spatial data warehouse. Furthermore, we introduce a set of guidelines to aid smart cities managers to implement the proposed architecture. These guidelines describe and discuss important issues that should be faced by the managers. We validate our architecture with a case study that uses real data collected by IoT devices in a smart city. This case study encompasses the execution of three different categories of spatial queries, demonstrating the architecture's efficacy and effectiveness to support spatial analytics in the context of smart cities.
Analisis Perbedaan Perbankan Syariah Dengan Perbankan Konvensional

Islamic banking is a financial institution that has a very important role in advancing the Indonesian economy as well as responding to the community's need to use a banking system based on sharia principles. However, sometimes there are many perceptions that Islamic banking is the same as conventional banking. Islamic banking has fundamental differences with conventional banking, namely regarding legal aspects, organizational structure, financed business activities and work environment. Sharia banking operations are based on sharia principles, namely the principle of profit sharing, the principle of buying and selling and leasing by running a business through mudharabah, musyarokah, murabbahah and ijaroh contracts. While conventional banking provides services in payment traffic with the principle of setting interest for both deposit and loan products (credit) and applying various fees in the form of nominal and certain percentages.
Analysis of a linear dipole antenna system for measurement the complex dielectric permittivity

In the paper, the use of linear dipoles for measuring the dielectric characteristics of subsurface media is examined. The given approach is based on the analysis of the mutual impedance of a system consisting of two linear dipole antennas and located above a surface of a layered half-space. The mutual impedance of two antennas depending on height above the surface and dielectric characteristics is investigated for the case of a homogeneous half-space in the 400 to 2000 MHz range. A measuring technique for the permittivity variations of homogeneous media is suggested. In addition, the influence of surface imperfections (deviations of the antenna heights from their nominal value) and dependence of calibration curves on the passive reactance in the measuring antenna are estimated. The comparison of theoretical and experimental results for the case of grey field soil with a rather uniform distribution of humidity is carried out.
An Evaluation of Local Mentor Support in AE E-Teacher Educational Technology Integration Online Teacher Training Course

This study addressed a different approach to online language teacher training programs. The researchers investigated the pros and cons of having local mentor support for an online course titled Using Technology in the English Language Classroom provided by the AE E-Teacher Program. The course was offered to preservice teachers from 24 different universities across Turkey. The study collected data through a pre- and post-online survey and individual semistructured interviews. The results revealed that while local mentoring as a supplement to the main course content contributed to teacher candidates’ emotional and professional attachment to their profession by helping them relate theory to contextualized educational settings, it can still be improved by the integration of more interactive tasks that would help the attendees refer to specific practical implementation of the educational technology tools introduced in the program.
THE ROLE OF AUTOMOBILE SECTOR IN GLOBAL BUSINESS CASE OF PAKISTAN

The global automobile sector is among the driving forces of worldwide economies. Similarly in Pakistan, the automobile sector is the one of greatest industries. Although the automobile is one of the leading private sectors in Pakistan, the industry is largely protected from the external race. Over the eras, the automotive manufacturing consumes made a known run-of-the-mill presentation in rapports of continual and continuous progress. The vehicle manufacturing of Pakistan ensures not to partake a noteworthy part in the overall additional worth of the industrial segment. This study is finding out the effects of high duties, production, technology, and government policies on automobile growth in Pakistan. It will contribute to other important factors that affect the growth of the Automobile Industry worldwide and specially in Pakistan. Many studies use the Balassa index to analyse comparative global trade benefits, which have been shown (particularly in agriculture), but the selected automotive industry has novel study possibilities. This research focuses on the competitiveness of the car industry, a crucial sector because of its high added value, competitive market, growing technical demands and a high level of employment. The objective of our article is to analyse the comparative benefits indicated by Markov's transition probability and the caplan-meier survival function of the global car trade, and the duration and stability of the Balassa indices. Data sources for 1997-2016 are worldwide HS6 car shipments. The article has arrived at several findings. Initially, analysing the global vehicle trade, it was found that the USA, China, Germany and Japan were the greatest vehicle manufacturers, but in the time examined, the main exporters were Germany, Japan and Canada, collectively accounting for 40% of all goods shipped, with 71% of the top 10 nations. Second, the most traded/exported automotive product, as we analysed it, was a worldwide vehicle with just dazzling internal ignition (1500-300cm 3) (870323), representing more than 40% of the whole 1997-2016 export of vehicles. Third, the Balassa calculations reveal that in every period evaluated by the most prominent automotive exporters in the world, Spain and Japan had the largest comparative advantages. This is a descriptive correlational study and the primary purpose is to examine variables and relationships. This study is conducted in the education sector in Karachi, Pakistan with four variables to investigate the causal relationship among different variables. This study constructed a conceptual framework to illustrate a causal relationship by defining the relevant variables. It indicates the independent variable (the cause) and the dependent variable (the effect). There is a positive relationship between production and automobile growth. The effects of Duties are 0.294 on automobile growth and the effect of government policy is 0.177 on automobile growth and the effect of production is 0.152 on automobile growth and the effect of technology is 0.150.
Characterization and Measurement of System Stability

For the characterization of noise and stability of any measuring instrument a new and very practical method is introduced. It follows the principles of the "Allan variance" well estabilished for the characterization of the stability of frequency standards. The plot of the Allen variance versus integration time enables one to determine the different types of noise power spectra from the output of any instrument. In particular, the best range of the integration time for optimum use of the system can accurately be evaluated. Theoretical considerations and experimental results with components of the 3-m radiotelescope of Univ. of Cologne are presented.

Potential Bacterial Antagonists for the Control of Charcoal Rot (Macrophomina phaseolina) in Strawberry

The effect of antagonistic bacteria to control Macrophomina phaseolina was evaluated under in vitro, growth chamber, greenhouse and field conditions. A total of 177 bacteria, isolated from Athrocaulon macrostachyum rhizosphere of the Lebrija marsh, were screened for their potential against M. phaseolina (causes charcoal rot in strawberry) by dual culture assay. Of these isolates, 14 most promising strains were molecularly identified by the 16S rDNA sequencing method using the EzBioCloud database. These strains were tested for in vitro hydrolytic enzymes, HCN production, and biocontrol against M. phaseolina in strawberry plants. All the 14 strains produced, at least, one hydrolytic enzymatic activity and one of them, which belongs to Brevibacterium genus (Hvs8), showed the lowest records of disease incidence (20%) and severity (0.4). With these results, greenhouse and field trials were carried out with the Hvs8 strain, compared to non-treated control. In the greenhouse assays, Hvs8 strain increased root dry mass by 30%, over the control. In the field trials, production and fruit quality were not significantly different between Hvs8 treatment and non-treated control, but plant mortality and plant mortality associated to M. phaseolina decreased by more than 24% and 65% respectively, in Hvs8 treatment. This study suggests that Brevibacterium sp. Hvs8 strain could be a candidate for controlling charcoal rot in strawberry.
Comparative clinical efficacy of anatomic plate and Kirschner wire internal fixation in midshaft clavicle fractures: A meta-analysis

Midshaft (mid)-clavicle fractures are the most common type of clavicle fractures. The Kirschner wire (KW) and anatomic plate (AP) are two commonly used surgical treatment methods for mid-clavicle fractures, of which the use of an AP appears to be a more effective option. The present study performed a meta-analysis of a number of published studies on the treatment of mid-clavicle fractures with APs and KWs, in order to compare the advantages and disadvantages of the two treatments, so as to select a more effective treatment approach. The articles were obtained from several databases, including Cochrane Library, PubMed, Embase, CNKI, Wanfang, VIP and Chinese Biomedical Literature Database. The search period was from database establishment to June, 2021. Research was obtained by two authors who individually searched the aforementioned databases. For controversial studies, decisions were made by two authors (JZ and LW). A total of 20 studies involving 1,739 patients were included in the meta-analysis, including eight randomized controlled studies and 12 cohort trials. The results of the meta-analysis suggested that: Compared with the KW group, the AP group exhibited significant differences in incision length [standardized mean difference (SMD)=2.40; 95% confidence interval (CI), 1.93-2.86], constant function score (6 months; SMD=1.59; 95% CI, 1.29-1.89) and fracture healing time (SMD=-1.48; 95% CI, -2.09 to -0.87) (P<0.05). However, no significant differences were observed in the duration of the surgery (SMD=1.19; 95% CI, -0.19-2.57) and intraoperative blood loss (SMD=0.10; 95% CI, -3.13-3.32) (P>0.05). Compared with the KW group, significant differences were observed in post-operative efficacy (OR, 4.81; 95% CI, 3.10-7.46) and the incidence of post-operative complications (OR, 0.16; 95% CI, 0.05-0.55) in the AP group (P<0.05). On the whole, the AP and KW are two common materials for the clinical surgical treatment of mid-clavicle fractures. The present study confirmed that there was no significant difference between the two treatments as regards the duration of surgery and intraoperative blood loss; however, for post-operative shoulder joint function recovery, fracture healing state and healing time, the AP was significantly more effective than the KW. The post-operative complication rate of the AP group was significantly lower than that of the KW group. However, further prospective, large-sample randomized controlled studies are required to provide more concrete evidence for verification.
Spatiotemporal Evolution of the Online Social Network after a Natural Disaster

Social media has been a vital channel for communicating and broadcasting disaster-related information. However, the global spatiotemporal patterns of social media users’ activities, interactions, and connections after a natural disaster remain unclear. Hence, we integrated geocoding, geovisualization, and complex network methods to illustrate and analyze the online social network’s spatiotemporal evolution. Taking the super typhoon Haiyan as a case, we constructed a retweeting network and mapped this network according to the tweets’ location information. The results show that (1) the distribution of in-degree and out-degree follow power-law and retweeting networks are scale-free. (2) A local catastrophe could attract significant global interest but with strong geographical heterogeneity. The super typhoon Haiyan especially attracted attention from the United States, Europe, and Australia, in which users are more active in posting and forwarding disaster-related tweets than other regions (except the Philippines). (3) The users’ interactions and connections are also significantly different between countries and regions. Connections and interactions between the Philippines and the United States, Europe, and Australia were much closer than in other regions. Therefore, the agencies and platforms should also pay attention to other countries and regions outside the disaster area to provide more valuable information for the local people.
Optimal Design and Performance Analysis of Solar PV Integrated UPQC for Distribution Network

The increasing number of electricity consumers results in power quality problems in the distribution system. Solar photovoltaic integrated unified power quality conditioner (UPQC-PV) is a widely adopted device that can improve a distribution system's voltage and current quality. This paper presents an optimal design and performance analysis of a unified power quality conditioner integrated with a double-stage solar photovoltaic system (UPQC-PV). A technique based on sequence component detection (SCD) and unit vector template generation (UVTG) is proposed for the UPQC-PV control. Using a SCD technique, the fundamental active component of the distorted load current is estimated, which is used to generate a reference signal for shunt compensator control. The UPQC-PV consists of shunt and series compensators; the shunt compensator eliminates the harmonic currents produced by nonlinear loads and extracts the active power generated by the solar PV array. In addition, the series compensator compensates for the grid side power quality problems such as voltage sags/swells. Hence, the proposed system can simultaneously perform clean energy generation and power quality improvement. The UPQC-PV system performance is evaluated in MATLAB-Simulink software under different grid conditions.

Additionally the theoretical framework of identification types also requires further research to obtain a more objective analysis that can increase the reliability and external validity of the studies.Practical implications: By validating the type identification model, businesses are able to determine what type of loyalty program the organizations holds and what kind of actions are required in order to further develop the program.Originality/Value: Establishing an updated framework from which future managers and researchers can obtain an understanding of the different factors that has of importance for the phenomenon.
SIRT1 Promotes Osteogenic Differentiation in Human Dental Pulp Stem Cells through Counteracting the Activation of STAT3

Human dental pulp stem cells (hDPSCs), which are characterized by self-renewal capacity and the ability of multilineage differentiation, have gained increased attention in regenerative medicine recently. Histone acetylation modulator proteins (HAMPs) are a protein family that mediates the modification and identification of histone acetylation and participates in various critical cellular processes. Here, we comprehensively surveyed the expression profile of HAMPs during osteoblast differentiation of hDPSCs and found that the HDAC class III pathway was upregulated, whereas the signal transducer and activator of transcription 3 (STAT3) signaling was downregulated during osteogenesis. Further laboratory research demonstrated that Sirtuin-1 (SIRT1), a class III HDAC, was upregulated and STAT3 activation was downregulated during osteogenic differentiation. SIRT1 counteracted the activation of STAT3 to promote osteogenic differentiation of hDPSCs at 7 and 21 days in both Western blot assay and chemical staining, which highlights the promising utility of SIRT1 activators in hDPSCs-based therapies for bone augmentation strategies and provides clinical insights that may lead to the development of osteogenic agents.

Large-Scale System for Social Media Data Warehousing: The Case of Twitter-Related Drug Abuse Events Integration

Social media data become an integral part in the business data and should be integrated into the decisional process for better decision making based on information which reflects better the true situation of business in any field. However, social media data are unstructured and generated in very high frequency which exceeds the capacity of the data warehouse. In this work, we propose to extend the data warehousing process with a staging area which heart is a large scale system implementing an information extraction process using Storm and Hadoop frameworks to better manage their volume and frequency. Concerning structured information extraction, mainly events, we combine a set of techniques from NLP, linguistic rules and machine learning to succeed the task. Finally, we propose the adequate data warehouse conceptual model for events modeling and integration with enterprise data warehouse using an intermediate table called Bridge table. For application and experiments, we focus on drug abuse events extraction from Twitter data and their modeling into the Event Data Warehouse.
