The total output value of the construction industry, a pillar industry of China, is continuously growing with the expansion of the production and operation scale of Chinese construction enterprises. The extensive high-input mode has promoted the economic growth of the construction industry. Despite the fruitful and outstanding results, production inefficiency has become especially prominent. Though developing rapidly, China{\textquoteright}s construction industry possesses fewer ecological investments, accompanied by low environmental awareness and little importance to environmental protection, constantly failing to eliminate high energy consumption, high investments, and high emissions. In addition, the contradiction between the economic growth of the construction industry and the ecological environment remains evident. In this paper, the production efficiency of China{\textquoteright}s construction industry was transversely and longitudinally measured using the DEA-Malmquist index method, followed by a further analysis of the factors influencing the production efficiency of China{\textquoteright}s construction industry based on the Tobit regression model. The results show that the average production efficiency of China{\textquoteright}s construction industry is the highest in the East, moderate in the West, and lowest in the centre. The number of construction enterprises, per capita capital, industrial structure, the proportion of state-owned capitals, and GDP are significant at 1\%, 10\%, 1\%, 1\%, and 1\%, respectively. The research results can provide theoretical reference for reasonably establishing an ecological efficiency evaluation system for the construction industry to analyze the differences in environmental efficiency among different provinces and regions, further find out the key factors influencing ecological efficiency, propose the corresponding pertinent policy suggestions, and ultimately improve the ecological efficiency of China{\textquoteright}s construction industry.

Converting handwritten prescriptions into electronic format offers several advantages and is crucial for modern healthcare systems. It is essential nowadays because of some factors such as {\textendash} Legibility and Accuracy: Handwritten prescriptions can be challenging to read and interpret; accessibility and Portability: Electronic prescriptions can be easily stored; Decision Support Systems: By digitising prescriptions, healthcare systems can integrate them with electronic health records (EHRs) and utilise decision support systems. Convolutional neural networks (CNNs) are a class of deep learning algorithms that have proven effective in extracting handwritten text from various documents, including medical prescriptions. By leveraging CNNs for handwritten text extraction, healthcare systems can automate the process of digitising prescriptions, reducing manual effort and potential human errors. This enables seamless integration with electronic systems, facilitating better patient care and overall healthcare management. In this paper, we have trained the CNN model for different parameters and observed the accuracy and loss for various parameters. We got a maximum training accuracy of 89\% and a maximum testing accuracy of 70\%.

This paper presents an approach based on supervised machine learning methods to build a classifier that can identify text complexity in order to present Arabic language learners with texts suitable to their levels. The approach is based on machine learning classification methods to discriminate between the different levels of difficulty in reading and understanding a text. Several models were trained on a large corpus mined from online Arabic websites and manually annotated. The model uses both Count and TF-IDF representations and applies five machine learning algorithms; Multinomial Na{\~A}{\textasciimacron}ve Bayes, Bernoulli Na{\~A}{\textasciimacron}ve Bayes, Logistic Regression, Support Vector Machine and Random Forest, using unigrams and bigrams features. With the goal of extracting the text complexity, the problem is usually addressed by formulating the {\^a}{\texteuro}\~{}level identification{\^a}{\texteuro}{\texttrademark} as a classification task. Experimental results showed that n-gram features could be indicative of the reading level of a text and could substantially improve performance, and showed that SVM and Multinomial Na{\~A}{\textasciimacron}ve Bayes are the most accurate in predicting the complexity level. Best results were achieved using TF-IDF Vectors trained by a combination of word-based unigrams and bigrams with an overall accuracy of 87.14\% over four classes of complexity.

\ One of the challenges facing today{\textquoteright}s researchers is how to find qualitative information that meets their needs. In scientific research, the quality of information is very important for institution quality improvement and research validation. The main purpose of the paper is the proposal of a scientometric annotation approach to improve retrieval system performance and meet researchers{\^a}{\texteuro}{\texttrademark} needs. In this work, we discuss how to use scientometrics in document annotation to improve information quality. One possible solution to this problem is to automate and facilitate the selection of qualitative scientific documents by enriching the document annotation process with scientometric criterion. Our approach provided better performance for retrieval system compared to BM25 retrieval model. The best performance was supplied by the integration of document citation number and journal or conference ranking. The best improvement rate was 34.21\% in F-measure, 52.22\% in nDCG, 27.45\% in MAP and 83.33\% in P(k). An important implication of this finding is the existence of correlation between research paper quality and paper relevance.

The number of citations has been used for measuring the significance of a paper. Moreover, we have the following question: which paper is the most important if there are some papers with the same number of citations? Some measures have been introduced to answer this question: one of them is PageRank. We use the Science Citation Index Expanded from 1981 to 2015 to calculate the number of citations and the Google number in the citation network consisting of 34,666,719 papers and 591,321,826 citations. We clarify the positive linear relationship between the number of citations and the Google number, as well as extract some outliers from this positive linear relationship. These outliers are considered to be extremely prestige papers. Furthermore, we calculate the mean values of the number of citations and the Google number for all journals, construct a new measure of journal influence, and extract extremely prestige journals. This new measure has a positive and medium correlation with the impact factor, Eigenfactor score, and SCImago Journal Rank.

This paper seeks to depict online rumor retransmission using three main constructs, namely, message characteristics, user characteristics and retransmission outcomes. In particular, it teases retransmission outcomes into volume, immediacy and lifespan of rumor tweets. The dataset was drawn from 322 original Twitter messages which generated some 5,700 retweets about the rumored death of Lee Kuan Yew (LKY). Content analysis and statistical tests were conducted. The results confirm the robustness of the research model. Specifically, rumor message characteristics affect retransmission in terms of volume, immediacy and lifespan. Additionally, user characteristics are positively related to volume and immediacy. Finally, user characteristics have a moderating effect on the relationships between rumor message characteristics and retransmission outcomes. This paper illustrates the applicability of the information diffusion model on online rumor retransmission which hitherto has yet to be attempted. Moreover, it granularizes the concept of online rumor retransmission into three important outcomes, namely, volume, immediacy and lifespan. On the practical front, this paper has implications for organizations seeking to combat rumors.

\ In this workm we study the fault prediction in fuzzy discrete event systems. Fuzzy discrete event systems are proposed to deal with vagueness, impreciseness, and subjectivity in real-world problems. The verification is divided into two steps. In the first step, we give a method to construct a Diagnoser. And in the second step, based on the structure of diagnoser we give the necessary and sufficient conditions to verify the future occurrence of the fault. The newly proposed approach allows us to deal with the problem of fault prediction for both crisp DESs and FDESs. Finally, an example is provided to illustrate the efficiency of the proposed approach.

\ Diverse factors such as the development of globalisation processes and an ever-changing economic environment are encouraging companies to access external markets. Localisation, the activity that makes a certain product {\textendash}for example, a websitelinguistically and culturally appropriate for a particular country and language, is an extremely valuable tool for companies who want to pursue internationalisation strategies. In Spain, small and medium enterprises (SMEs) make up over 99\% of the country{\textquoteright}s business structure. However, the localisation of their websites is often deficient. An analysis of 70 Spanish SME corporate websites was performed with the purpose of assessing the degree and characteristics of website localisation in the SME sector in Spain. It was found out that the web presence of Spanish SMEs presents serious deficiencies and that the contents offered on their websites are often poorly localised, if at all. The information gathered enabled us to put forward a series of practical recommendations for SME corporate website localisation.

In system engineering process, descriptive system models seem to be insufficient in order to perform a system verification which fulfils various stakeholders{\textquoteright} requirements. This aspect is well handled by simulation process through the use of several simulation techniques or algorithms. As a consequence, design process efficiency is considerably reduced by the fact that both system modeling and simulation tools are often used separately. This study introduces an integration process to unify the potential provided by systems modeling languages and simulation environments, through the definition of a Domain Specific Language, namely Simulation Modeling Language, that is built on the basis ofa deep study of common constructs, semantics and modeling methodologies of several simulation environments, in addition to the specification of a model transformation between this language and a simulation environment (MATLAB/SImulink) in order to illustrate both its importance et its efficiency in our integration approach. Through the specification of its syntaxes and semantics, the defined intermediate modeling language allows modeling systems by using common constructs and modeling methodologies of simulation process in order to ensure their modeling with simulation environments\

In order to improve the effectiveness of network intrusion detection, a network intrusion detection model based on particle swarm optimization algorithm and neural network is proposed. Firstly, the feature of network intrusion detection is collected, and important features are selected by using particle swarm optimization algorithm to effectively remove the invalid feature; then BP neural network is used to build intrusion detection classifier, finally KDD 99 data is used to analyze performance of the model. The results show that the proposed model can improve accuracy of network intrusion detection, and the detection speed can meet the practical requirements of network security.

\ In developing cities such as in Jakarta, there are a lot of vehicle parking locations that still use conventional methods, which can harm drivers and also parking area owners alike, the process is slow and unsafe, making many people around feel afraid to use parking locations that are still conventional, the conventional parking lots in Jakarta is too many, sometimes also make people have no other choice but to use unsecured parking lots, theft is the main factor that is difficult to avoid, especially in developing countries like Indonesia, which are not safe, and the location of the parking lot that is very open, makes a lot of opportunities which of course can be used by thieves or irresponsible people. Not only thieves, drivers who do not want to pay for parking, are also a problem for owners of parking lots. With the problems of these users, we plan to make modular parking applications that can be installed easily and cheaply, but because our group is not so large, there are several challenges that we face, such as time and requirements that can increase later, with thus we plan to make this parking application using the Extreme Programming method, which is possible and very suitable for the problems that our group is facing. The use of Extreme Programming turned out to be very helpful, and can also produce an application that matches the existing user stories.

The objective of this study was to implement a micropayment system pilot based on an interoperability enabling platform (in this case, Smart-M3) for small businesses with restricted resources, scarce labor force, and a growing number of products and vendors. In these small and medium-sized enterprise (SME) contexts, piloting systems of this kind is usually problematic because of its immediate impact on the core business and monetary transactions that are essential for SMEs. An account-based system was considered an appropriate starting point for the micropayment system pilot. The applicability of the Smart-M3 platform was then validated by the implementation of the system. Lastly, a summative evaluation was carried out by interviewing direct stakeholders, to enrich the observations from the validation. The results of the study show that the implemented system provides small businesses with opportunities to reduce costs and more efficiently use resources, adding new devices and systems, new ways to produce services, andreal-time tracking of the sales process, as well as utilization of the data collected from the system.

In this paper, an approach of exception detection is presented for web service composition by improved Bayesian network. Firstly, the topological structure of Bayesian network is established, where the causal relationships between underlying web services are mapped to Bayesian network in service combination process. The conventional Bayesian network algorithm is improved to satisfy the demand of better conversion from nodes in web service composition to nodes in Bayesian network. Secondly, the parameter setting in Bayesian network is explored for determining the prior probability of service nodes and the conditional probability of service output node. Thirdly, the algorithm of the improved exception detection model is introduced, with the aim of locating the web services that cause exceptions in the execution of composite services.

In order to maximize the lifetime of MANETs, traffic should be sent through a shortest path that does not contain nodes with low residual energy and consumes minimum total transmission power. The above objectives cannot be satisfied simultaneously by applying the existing power aware routing algorithms. For this reason, several power-aware routing approaches have been proposed in the literature attempting to maximize the network lifetime. An interesting approach called Minimum Drain Rate (MDR) aims to predict the lifetime of nodes according to the current traffic conditions. However, it does not guarantee that the total transmission power is minimized over a chosen route. In this paper, we provide an new approach called Secure Extended Optimal Energy Drain Rate (SEOEDR) able to extend the MANET lifetime and duration of the path, and also to minimize the total transmission power consumed per packet. In our approach, the traffic is routed such that the energy consumption is balanced among the nodes in proportion to their energy reserves. We also handle the selfishness of nodes by considering the node reputation while making the routing decisions. It results in selection of routes that are simultaneously energy efficient and reliable.

On consideration of this aspect, we propose an approach to feature selection and classification of multi-source remote sensing images based on Mallat fusion and residual error in this paper. Firstly, the fusion of multi-source images can provide a fused image which is more preferable for classification. And then a featureselection scheme approach based on fused image is proposed, which is to select effective subsets of features as inputs of a classifier by taking into account the residual error associated with each land-cover class.

Traditionally, P2P primitives and mechanisms have been implemented by means of keyword-based search and matching operations. Modern P2P systems require more complex query functionalities, beyond capabilities of DBMS-inspired models and algorithms.

The ontologies imported in GraphOnto are parsed so that graphical ontology browsing and editing interfaces are automatically generated. The ontologies are used to guide the semantic multimedia annotation in a standardized manner. OWL Ontology mappings, expressed using OWL constructs, are supported and allow the definition of personalized ontologies. Personalization of the GraphOnto user interface on the application, task and user levels is provided. In addition, GraphOnto interoperates with an MPEG-7 Repository both for semantic entity reuse during multimedia content annotation and for semantic description storage.

Creation of these presentations, and interactions with them during their play-out, require an effective mechanism for handling the specifications dynamically. These specifications could result in inconsistencies, which need to be checked and resolved. Moreover, consistent presentations could become inconsistent due to interactions during the playout. Our main contribution is the design of an algorithm which aids in resolving these consistency issues dynamically and efficiently. The other salient features of our approach are a new composite spatio-temporal operator and an effective relaxation policy. We have developed a prototype which helps to study the effectiveness of the proposed approach.

In this paper, a system, RitroveRAI, addressing the general problem of enriching a multimedia news stream with semantic metadata is presented. News metadata are explicitly derived from transcribed sentences or implicitly expressed into a topical category automatically detected. The enrichment process is accomplished by aligning individual audiovisual segments with news or journal articles reachable trough the Web.
