Currently, some universities and colleges in Palestine use a traditional assessment method to evaluate their faculty members' performance each semester, while some use e-forms that are being evaluated manually. However, these processes are not flexible or accurate enough to give fair and non-prejudiced feedback. Moreover, it takes a long time to ensure the information quality of the data inputs as...
Rare colored capsule (RCC) is the capsule which is mixed in the normal product but with different color. To detect this kind of capsules online, a method based on RGB color space and using HSV color difference formula is proposed in this paper. Considering HSV color space with more balanced color-difference perception, the original RGB formatted capsule image is transformed to HSV color space for...
In an effort to generate and retain student interest in STEM fields, this work focused on providing middle school teachers with resources to engage students using hands-on activities and demonstrations directly related to the state science standards. The project involved generating a library of content for 8th grade physical science standards. The demonstrations and activities were specifically selected...
Sale of ticket, the very first stage in rail service for passengers, is critical to the management of the whole system. Based on information of the ticket office at Shijiazhuang South, a queuing simulation system is built. Three indicators, namely usage level, number of customers and queuing time, are obtained by running simulations based on different parameters during peak and off-peak periods. Therefore,...
We report here how depth of field (DOF) affects the aesthetic appeal of photographs for different content categories. 339 photographs spanning eight categories were selected from Flickr, Google+, and personal collections. First, we classified the 339 photographs into three levels of depth of field: small, medium, and large. Then, we asked participants to rate the aesthetic appeal of these photographs...
Thermodynamic calculation of isobutane dehydrogenation reaction have been finished in detail by EXCEL program. The relationships of reaction temperature in isobutane dehydrogenation with enthalpy, Gibbs free energy and chemical equilibrium constants have been obtained and the option conditions have been given. The influences of the side effects of the main reaction are estimated. The influence of...
Based on the research of traditional assessment structure and informatization, we propose a novel five-unit assessment structure. It includes data state unit, index system unit, assessment system unit, results feedback unit, management services unit. This paper describes the content of five-unit assessment structure. Compared to traditional assessment structure, the five-unit assessment structure...
Information is not only the basic element of management, but also an important prerequisite of the various management functions. In essence, sports management realizes the function of the system through coordinating the relationship between internal resources, external environment and the predetermined target with sports information. So the sports information resources development is of great importance...
Intrusion detection system (IDS) is an important component to ensure network security. In this paper we build an online Naïve Bayes classifier to discriminate normal and bad (intrusion) connections on KDD 99 dataset for network intrusion detection. The classifier starts with a small number of training examples of normal and bad classes; then, as it classifies the rest of the samples one at a time,...
Primary care research databases provide a significant resource for health services and epidemiological research. However since data are recorded primarily for clinical care their suitability for research may vary widely according to the research application or recording practices of individual general practitioners. A methodological approach for characterising data quality is required. We describe...
In underwater wireless sensor network (UWSN), node estimation poses a great challenge using conventional protocol techniques due to underwater propagation characteristics. For this reason, a cross-correlation based technique is applied to estimate the number of nodes, which is equally suitable for any environment networks. The nodes are considered as acoustic signal sources in an underwater network...
To efficiently exploit network resources operators do traffic engineering (TE), i.e., adapt the routing of traffic to the prevailing demands. TE in large IP networks typically relies on configuring static link weights and splitting traffic between the resulting shortest-paths via the Equal-Cost-MultiPath (ECMP) mechanism. Yet, despite its vast popularity, crucial operational aspects of TE via ECMP...
In this study, quality of class of final product is intended to automatically determine by setting properly distribution and number of defects on wood. Nowadays number of defects and quality of wood is determined by their distribution. The most common type of defect is called knot by reducing the resistance of a wooden part. Selection and classification of wood manually is difficult, costly and time-consuming...
With the advancement in the technology, this era of Internet has witnessed a bloom in the Social Networking sites popularity. Social Networking sites facilitate the users with features like sharing personal information, making friends, developing new relationships, giving rise to new privacy concerns, etc., allowing only reliable people in one's network. Here comes in the concept of ‘Trust’. How can...
The main purpose of workload measurement is to identify conditions for overload so that they can be avoided by design. The operators' workload peak is difficult to measure by subjective evaluation. Pupil diameter is widely used as a factor to measure workload sensitively, so it's necessary to study the relationship between the workload peak and pupil diameter measurement. Eight trials were designed...
Studies have shown that the use of verbal encouragement strategies in education is able to maximize learning. This idea is derived from traditional classroom settings where teachers use a multitude of behavioral strategies to maintain the students' level of engagement. Motivated by these educational practices, we discuss the use of a Socially Interactive Robotic Tutor (SIRT) that incorporates a variety...
This paper describes results from a two-year-old Whole-School STEM Initiative at Laing Middle School of Science and Technology in Mount Pleasant, SC. This Initiative uses engineering design and technological tools to address mandated curriculum standards in all subjects, including Fine Arts. The program's goal is to teach students to solve a wide variety of problems using appropriate tools from science,...
In this paper, integrated Energy Storage System(ESS) and Uninterruptible Power Supply(UPS) is suggested. Integrated ESS and UPS system not only improves the efficiency but also prevents the grid voltage error situation. Using this system, change of characteristic at the load makes unbalanced 3-phase voltage. The comparison shows considerable discrepancy between sensed phase voltage and actual phase...
As a popular type of parallel evolutionary algorithms, distributed evolutionary algorithms (DEAs) are widely used in a variety of fields. To get better solutions of concrete problems, a scheme of subpopulation diversity based accepting immigrant in DEAs is proposed in this paper. In migration with this scheme, an immigrant will be put into its target subpopulation only if its current diversity is...
Over past few years, there has been a huge advancement in terms of Learning Management System (LMS) and online education. Behind this growth, the major reasons are the availability of open source LMS and their ease of customization. This paper proposes some new features for these pre-existing LMS, especially Moodle, such that the same LMS could also function as College / University Management System...
