HEAT SAVING IN EVAPORATIVE CRYSTALLIZATION BY INTRODUCING A HEAT PUMP

In this work theoretical calculations had been made for suggested methods of heating mother liquor in a crystallizer for both kinds of evaporative crystallization process. These suggested designs aim to reduce and save the consumption of heat which leads to reducing operational costs for the two kinds of crystallization. It was found that in direct evaporative crystallization: when a heat pump was added to heat the medium (hot air), it had saved energy consumption range between 81 % to 93 % at different values of coefficient of performance (COP). In the second type - indirect evaporation, when a heat pump was added on line containing the mixture of vapor from crystallizer and steam from jacket outlet, this mixture becomes a heat source to the heat pump in order to preheat the inlet steam to the jacket. Calculations of this suggested design showed that the saved energy consumption was 8 % to 26 % at different COP.
Using Complex Event Processing for Modeling Semantic Requests in Real-Time Social Media Monitoring

Social media analytics has been attracting considerable attention in both research and industry due to the increasing popularity of social media usage. As a subset, social media monitoring describes the process of continuous monitoring of a subject matter in social media. From our point of view, the key requirements for such systems are i) high throughput and real-time processing of incoming data, ii) a user-friendly way to define complex situations of interests that make use of formalized background knowledge and iii) capabilities to perform actions based on gained insights instead of a pure monitoring system. In this paper, we propose a system for (pro) active, real-time social media monitoring. Firstly, we describe the conceptual architecture of our system and necessary pre-processing steps. Secondly, we introduce our concept of semantic requests that is capable to extend event pattern definitions with background knowledge. Finally, we show the usefulness of this system in two different domains: Real-time political opinion tracking and proactive establishment of relationships with consumers in order to perform a new form of real-time marketing. The main advantage of our approach is a simplified, expressive way to formulate event patterns in social media applications.
An Investigation of Sensitivity on Bagging Predictors: An Empirical Approach

As growing numbers of real world applications involve imbalanced class distribution or unequal costs for mis- classification errors in different classes, learning from imbalanced class distribution is considered to be one of the most challenging issues in data mining research. This study empirically investigates the sensitivity of bagging predictors with respect to 12 algorithms and 9 levels of class distribution on 14 imbalanced data-sets by using statistical and graphical methods to address the important issue of understanding the effect of vary- ing levels of class distribution on bagging predictors. The experimental results demonstrate that bagging NB and MLP are insensitive to various levels of imbalanced class distribution.
TWITTER SENTIMENT ANALYSIS

With the advancement of web technology and its growth, there is a huge volume of data present in the web for internet users and a lot of data is generated too. Internet has become a platform for online learning, exchanging idea s and sharing opinions. Social networking sites like Twitter, Facebook , Google+ are rapidly gaining popularity as they allow people to share and express their views about topics, have discussion with different communities, or post messages across the world. There has been lot of work in the field of sentiment analysis of twitter data. This survey focuses mainly on sentiment analysis of twitter data which is helpful to analyze the information in the tweets where opinions are highly unstructured, heterogeneous and are either positive or negative, or neutral in some cases. In this paper, we provide a survey and a comparative analyses of existing techniques for opinion mining like machine learning and lexicon-based approaches, together with evaluation metrics. Using various machine learnin g algorithms like Naive Bayes, Max Entropy, and Support Vector Machine, we provide research on twitter data streams.We have also discussed general challenges and applications of Sentiment Analysis on Twitter.

An Interactive Learning Environment For Dsp

This paper presents a new version of the Java DSP (J-DSP) education software which encompasses a comprehensive Digital Signal Processing (DSP) learning environment.The goal is to create a one stop learning environment for students that wish to gain insight into DSP concepts.It combines html and Java based technologies to create an integrated and highly interactive simulation interface.The whole idea of this integrated environment revolves around a web-based DSP quiz.The quiz has many attractive features, which provide students an opportunity to gain a thorough understating of DSP theory.Different learning tools are combined with the interactive online quiz and are also synchronized with J-DSP simulations.Every quiz is accompanied with several helping features where users can access the instructor's notes and external links that contain simulations, lecture videos, and instructional J-DSP animations.This new environment also supports multiple J-DSP simulations, running concurrently.These simulations are completely independent with one another except for the certain predefined points at which two simulations can interact with each other and share their data.Assessments of the use of this new tool are also presented here.
Consistent Rounding of Edge Weights in Graphs

Often, the edge weights of graphs are given in implicitly infinite or overly high precision (think of Euclidean lengths) which leads to both theoretical as well as practical challenges. In this paper we investigate how to round edge weights of a given graph G(V,E,w) such that the rounded weights of paths satisfy certain consistency criteria. Natural consistency criteria are, for example, preserving optimality of paths, and bounding relative change in weight after the rounding procedure. Low precision edge weights allow for more space efficient implementations, faster arithmetic operations, and in general more stable and efficient algorithms. We present an ILP based rounding approach as well as a greedy rounding heuristic. We show experimentally for large road networks and grid graphs that our new rounding approaches are significantly better than common deterministic or randomized rounding schemes.
3D Virtual Learning Environment

Virtual Learning Environment (VLE) is the learning through electronic media where teachers and students are not in the same place, but the gap is bridged by the use of technologies. The aim of this study is to develop a 3D virtual learning environment (3D VLE). The three objectives of this study are (i) to gather the requirements of 3D VLE, (ii) to design the 3D VLE, and (iii) to develop the 3D VLE. The method consists of five phases; (i) literature review, (ii) requirement gathering, (iii) design, (iv) development and (v) evaluation. The prototype is developed by using Open Simulator, SLOODLE and Moodle. Future work includes enhancement for 3D VLE such as using gesture recognition to control the avatar movement.
Saliency-Based CBIR System for Exploring Lunar Surface Imagery

Abstract Saliency-Based CBIR System for Exploring Lunar Surface ImageryRecent NASA missions like the Lunar Reconnaissance Orbiter (LRO) have produced vastarchives of surface imagery which must be analyzed to locate landmarks with distinctive visualfeatures, like craters, which provide important information about geologic history and potentialmineral resources. Content Based Image Retrieval allows large archives of images to beefficiently queried based on visual content by indexing multidimensional feature vectorsextracted from the images. Unlike images of particular objects or scenes traditionally retrievedusing CBIR, surface images are not focused on any particular landmark so they must be pre-processed to identify Regions of Interest (ROI) to be indexed for retrieval. Previous workidentified ROIs using manual annotation and expensive detection algorithms for specific types oflandmarks, such as Crater Detection Algorithms (CDA). In contrast, this work utilizes a general-purpose saliency-based landmark detection algorithm for identifying ROIs which are thenindexed for retrieval using feature vectors extracted from the ROI images. We evaluate theretrieval performance of several feature vectors and assess the saliency-based landmark detectionperformance in comparison to a comprehensive crater database created using manual annotationand a CDA. Experimental results demonstrate the advantages of the general-purpose saliency-based CBIR system for exploring lunar surface imagery.
Would You Look At That! Vision-Driven Procedural Level Design

In this paper we present a technique for procedurally generating sections of 3D level geometry using computational evolution and guided by the visibility of certain game objects or areas during play. We show that certain level design goals can be achieved in the resulting levels, such as encouraging or dissuading player sightings of certain objects or locations. We also give details of a simple study of players on the generated levels, and discuss how this might be expanded to incorporate more complex problems related to level design.

Mobile And Wireless Networks Course Development With Hands On Labs

Rapid advances in wireless networks technologies present opportunities for innovative education at undergraduate and graduate level.Wireless networks courses become increasingly popular in colleges (including community colleges) and universities.However, there is a real concern with the lack of hands-on labs based active learning in computer science, engineering and technology curriculums.Hands-on project based learning is found to be the best way of learning and teaching wireless networking technologies.These hands-on projects also provide the problem based learning (PBL).In this paper, an undergraduate computer information technology special topic course in mobile and wireless networks is presented which is developed based on many hands-on lab activities.In learning the concepts of wireless networks via hands-on labs, students get ample opportunities to understand the underlying principles and concepts of wireless networks.These hands-on labs are chosen to provide sufficient challenges to the students that prepare the engineers and technologists for the next generation solutions.The level of difficulty for this course requires the prerequisites of networking course.For each hands-on lab, each team of students carry out the lab activities in order to successfully implement the particular wireless networks solutions.The course requires the students to collaborate among them and participate in active learning based modules.This paper elaborates innovative projects that are suitable for laboratory work in computer information technology curriculum.It explores both hardware and software components that are now being used for practical exercises in wireless networks courses.This paper discusses the hands-on labs for wireless networks such as site survey, MAC (Medium Access Control) layer settings, upgrading the firmware of wireless devices, etc.In addition, this paper also illustrates the wireless security labs which discuss how to set up WPA/WPA2 (Wi-Fi Protected Access) on Cisco and Linksys wireless access points (AP).
Hydrotopia: Integrating Civil Engineering And Humanities To Teach Water Resources Engineering And Management

This paper describes a unique integration of civil engineering and philosophy disciplines to create an interdisciplinary learning experience for a multi-discipline set of students from predominantly civil engineering and disciplines in the humanities and social sciences interested in professions in water resources.The course was developed and co-taught by professors from civil engineering and philosophy at the University of Utah with the goals of (1) cultivating in the next generation of civil engineering professionals -those responsible for planning, designing, managing, and operating water resources systems -a broader sensibility about the cultural climate in which they will operate, and (2) developing in humanists, social scientists and others who will be responsible for shaping and articulating that cultural climate a more grounded understanding of the practical water problems facing society and the constraints limiting engineering and technological solutions.Our pedagogical approach was to engage the students in case study analyses and mediated discussions of historical and emerging water engineering issues and projects in the western United States.Within the context of the case studies, students were exposed to philosophical and legal concepts, hydrologic principles, water resources engineering design and management techniques, water management modeling and analysis tools, social and behavioral science theories, water law, and more.One unique aspect of the course was the use of position papers with random assignment of position that forced students to analyze and argue points from perspectives outside of their discipline and sometimes against their personal beliefs.The outcomes of the course were assessed through a written survey, informal student discussions, and end-of-course ratings and comments.The collective feedback clearly indicated the civil engineering students broadened their understanding of the local, regional, and global context of water resources engineering projects and learned to decompose problems and develop logical arguments based on a broad base of knowledge.Most interesting, the civil engineers learned to analyze engineering issues using tools and constructs rooted in philosophy, while the philosophy students gained an appreciation of the challenges faced by engineers and the constraints of modern society related to water resources engineering projects.An unexpected outcome of the course was noted by the end of the semester with the engineers arguing their position papers from humanist perspectives and vice versa -humanists basing their arguments on traditional engineering approaches, e.g., cost-benefit analysis.
Developing Reading Material for Elementary Students in Tourism Area by Inserting Local Culture

This research and development (R&amp;D) aimed at 1) developing reading material for the fifth grade students of elementary schools in tourism area, and (2) investigating the quality of the material developed. To gather the data, this study used scoring rubric, questionnaires, observation sheets, interview guide, and test. This study used the development model proposed by Sugiyono (2011) and was developed based on the characteristics of good reading material proposed by Tomlinson (1998). The results showed that (1) reading material was developed by involving some of local contents and (2) reading material had high validity and practicality and was proven to be effective. It then can be concluded that to make good quality of a reading material, the development of it should involve local content and should be based on the criteria of good material.
Extracurricular Project Enhances Student Learning: A Case Study

Recently at Western Kentucky University's mechanical engineering thermal-fluids laboratory, a student worker, the author of this paper, was given the opportunity to design, build, and test (DBT) a dust collector performance test bed.The development of this test bed was inspired by an article in Wood Magazine, which described a method for testing the performance of various portable dust collectors.The test bed developed is being used for instructional purposes in one laboratory course in the Mechanical Engineering (ME) Program.Currently, the test bed is used in the program's Engineering Experimentation and Instrumentation course as a dust collector performance experiment.In this experiment students gain experience in method of measurement, selection of instrumentation, errors in and the proper use of pressure and air flow velocity measurements, and fan selection.Moreover, the test bed is capable of being used in a variety of other applications making it possible to be used in other laboratory courses in the future.The test bed incorporates a common portable wood shop dust collector with a duct system consisting of round metal duct, plastic flexible hose, and various duct transitions.In the current experiment, air flow rates and static pressures are measured in the duct for several different duct configurations, or operating conditions.These operating conditions are then used to plot the dust collector's fan curve and compare it to the manufacturer's listed performance characteristics.This paper focuses on the DBT process of the test bed and the development of the experiment.Moreover, an assessment of the project is provided through an analysis of the following project outcomes: 1) The student worker's learning experiences during the execution of this extracurricular project inclusive of both technical and project management aspects and 2) The impact of the implementation of this extracurricular project as a course experiment in the Experimentation and Instrumentation course as part of the ME Program's curriculum sequence.
The Assessment of Earthquake Preparatory Knowledge and Activities of Lebanese Engineering Students

Abstract The Assessment of Earthquake Preparatory Knowledge and Activities of Lebanese Engineering StudentsThe uncontrollable physical and social consequences of an earthquake remain a key challengeand a horrible nightmare for every vulnerable community. Such a fact necessitates a proactiverole of engineering institutions and an active engagement of the engineering community inplanning and preparing for future earthquakes. It is well documented that even in highseismically active regions; earthquake disaster preparedness has traditionally been overlookedand ignored by the general public, local community and government organizations. Lebanon hasrepeatedly suffered from devastating earthquakes that have recently become a source of deepconcern because of their imminent threat to the safety of unprepared communities, to poorlydesigned infrastructure facilities and to the fragile national economy. The quiescence of seismicactivities along the Lebanese faulting systems during the last few centuries has misled both theLebanese public and former governments’ officials about the existing seismic hazards and hasreduced their perception and awareness for earthquake preparedness. This study investigates thepreparedness of Lebanese engineering students to future earthquake disasters. Senior studentsattending engineering colleges in Lebanon (N=378) were surveyed to assess: 1) students’awareness to earthquakes, 2) students’ preparatory knowledge and practice to earthquakes, 3) thepossible link between awareness, preparatory knowledge and practice, and 4) how engineeringinstitutions, organizations and programs have affected their current awareness and preparedness.Although the findings indicated satisfactory seismic risk awareness across the majority ofparticipants, a poor level of earthquake preparatory knowledge that has negatively affectedpreparatory practices was revealed. It was clear that engineering students were unable to connectsuch awareness with the needed preparatory knowledge and activities to reduce such risks. Also,the role of engineering institutions and organizations has insignificant influence on bothpreparatory knowledge and practicing skills of participants. This article calls for theincorporation of earthquake disaster preparatory knowledge and practice into engineeringprograms across Lebanon and for the engagement of the Lebanese engineering sector inearthquake disaster risk reduction efforts.
Developing Listening Materials for the Tenth Graders

The needs survey shows that English listening skill of the students in the tenth graders of Indonesian Islamic High School or Madrasah Aliyah is not well developed. Consequently, the listening instructional materials based on standard of content 2006 used in the classes need to be advanced. The researcher used only one try out of the product, second revision in this study was the seventh step of Borg and Gall model operational product revision. This was done based on the result of the try out, and the final product (the production of the new materials). The development used in this study consists of needs survey, developing the materials, experts and teacher's validation, revision, try out, second revision and the final product. The product is found acceptable for the tenth grade students.
Lab Experiments In Probability

The subject of probability occurs not only in courses on probability and statistics, but also in courses covering stochastic processes.The concept of using probability models to describe reallife problems seems difficult for many students to grasp.Mathematical software, such as MATLAB, provides a useful tool in performing simulations using probability models.To assist students in forming a conceptual link between the results of actual experiments and practical situations in which the outcome is predictable only in a probabilistic sense, several simple projects involving repeated trials of an experiment are used in a course in probability or random signals.MATLAB programs simulating the same experiment are assigned as part of each project.This paper describes several such experiments and the associated MATLAB simulations.Students working in groups of three or four compare their experimental results with the MATLAB simulations and to the results of other groups in the class.By comparing the actual and simulated results, students may develop some confidence in the use of computational software to simulate experiments for larger numbers of trials than they can realistically perform in practice.
