Full textAbstract:
To remotely monitor your computer over the internet, you have to install this software on the remote computer (called as server) as well as on your own computer (called as client). When connected , Software Audit System software gives you the full mouse and keyboard control over your computer and you can see the whole screen of the remote PC on your own desktop. As we know that computer networks within companies and organizations become more extensive and more complex, there is a considerable growth in the number of software programs that are installed and used on the computer systems. In order to increase the reliability and efficiency of computer Systems, it is mandatory that we clearly understand and control all the computer programs that are being used. The problem may also arise when people installing unauthorized or copied computer programs on their Desktop PC's. It is necessary that we provide auditing tools that can facilitate audit data either locally or reside on to a central network manager and it gives the information related to the installed and used computer programs

Full textAbstract:
Vehicle swept path analysis presents an essential step while working on at-grade intersection and roundabout designs. Following the intensive development of computer-aided design (CAD) software in the past two decades, numerous CAD-based computer programs for vehicle movement simulation have been developed and commercially distributed. The accuracy of these simulation programs is usually verified by conducting experimental field tests in which real movement trajectories of design vehicles, equipped with global positioning system (GPS) receivers, are recorded. This paper proposes an improved methodology for retrieving vehicle movement trajectories from collected GPS data. The proposed methodology reduces the trajectory inaccuracy resulting from pavement grading characteristics and the inability to accurately install GPS receivers in relation to streamlined vehicle body. Results of field experiments show that the reduction of positioning errors in the horizontal projection is not smaller than 50.0 mm compared with previous studies.

Full textAbstract:
Abstract Motivation Molecular docking is a computational technique for predicting how a small molecule might bind a macromolecular target. Among docking programs, AutoDock Vina is particularly popular. Like many docking programs, Vina requires users to download/install an executable file and to run that file from a command-line interface. Choosing proper configuration parameters and analyzing Vina output is also sometimes challenging. These issues are particularly problematic for students and novice researchers. Results We created Webina, a new version of Vina, to address these challenges. Webina runs Vina entirely in a web browser, so users need only visit a Webina-enabled webpage. The docking calculations take place on the user’s own computer rather than a remote server. Availability and implementation A working version of the open-source Webina app can be accessed free of charge from http://durrantlab.com/webina. Supplementary information Supplementary data are available at Bioinformatics online.

Full textAbstract:
The article deals with the problem of improving the quality of the future teacher of mathematics by means of information technologies. There are two classes of software tools of mathematical direction such as 1) systems of computer mathematics which use traditional notation and methods of writing formulas (Maple, MatLab, Maxima, etc.), these systems are particularly effective in solving various applications, primarily mathematical modeling tasks in science and technology; 2) programs of dynamic mathematics which provide the possibility of dynamic changes of the original mathematical design, the study of the set of its numerical characteristics or their relations in dynamics (GeoGebra, Cabri, Mathkit, and the like). It is established that under the programs of dynamic mathematics it is necessary to understand the means of computer visualization of mathematical knowledge, which provide dynamic operation of various mathematical objects and the possibility of operative obtaining information about their properties. The term "computer mathematical tool" is specified as a virtual mechanism or algorithm of a computer program, or the program itself, which is used to create or study mathematical objects or their components through the numerical and geometric characteristics of the objects themselves. The methodical features of the use of computer mathematical tools have been distinguished: the possibility of dynamic changes in the drawing and observation of the trajectories of individual points opens the way for organizing the experimental and creative activity of all participants in the educational process; the ability to pre-install the tools or to expand the toolkit that simplifies the process of building or limiting tools; the computer frees the teacher from a debilitating check of the construction, and so on. The results of the experiment related to the study of the influence of the programs of dynamic mathematics on the level of academic students’ achievements have been presented. The positive influence of the use of dynamic mathematics programs and the corresponding mathematical tools on the level of mathematical preparation of schoolchildren has been proved. The necessity of preparing the future teacher of mathematics for using this tool in the process of professional activity has been indicated. The requirements of the standard of pedagogical education, the needs of school maths in the main school and the distribution of computer tools within the framework of training a modern mathematics teacher have been specified.

Full textAbstract:
Background & Objective: The paper explores a new instrument of computer vision to measure three-dimension deformation with an Internet of Things (IoT) system including Raspberry Pi, digital cameras and OpenCV programs in laboratory and field testing so as to monitor the potential deformation of a structure drainage well in a landslide. Methods: A chessboard pattern is detected in the image by the camera so that pixels of chessboard cornors can be recognized by OpenCV programs. X-direction, Y-direction and Z-distance changes can be casulated by the similar triangles relationship of camera pixels. For laboratory testing, standard deviations of the measurement were approximately 0.01 cm. Results: For field testing, the study installed four sets of Raspberry Pi in a drainage well within a landslide and employed OpenCV programs to interpret pixel changes of chessboards at four levels of the draiage well. Conclusion: Overall, the instrument can be employed for triaxial deformation monitoring of the construction in the field effectively and automatically.

Full textAbstract:
<p>The Mango Suite is a set of three freely downloadable cross-platform authoring programs for flexible network-based CALL exercises. They are Adobe Air applications, so they can be used on Windows, Macintosh, or Linux computers, provided the freely-available Adobe Air has been installed on the computer. The exercises which the programs generate are all Adobe Flash based. The three programs are: (1) Mango-multi, which constructs multiple-choice exercises with an optional sound and/or image; (2) Mango-match, which is for word/phrase matching exercises, and has an added feature intended to promote memorization, whereby an item must be matched correctly not once but an optional consecutive number of times; (3) Mango-gap, which produces seamless gap filling exercises, where the gaps can be as small as desired, down to the level of individual letters, and correction feedback is similarly detailed. Sounds may also be inserted at any desired points within the text, so that it is suitable for listening or dictation exercises. Each exercise generated by any of the programs is produced in the form of a folder containing all of the necessary files for immediate upload and deployment (except that if sound files are used in a Mango-gap exercise, they must be copied to the folder manually). The html file in which the flash exercise is embedded may be edited in any way to suit the user, and an xml file controlling the appearance of the exercise itself may be edited through a wysiwyg interface in the authoring program. The programs aim to combine ease of use with features not available in other authoring programs, toprovide a useful teaching and research tool.</p>

Full textAbstract:
Automated external defibrillators (AEDs) are portable devices about the size of a laptop computer, that deliver an electrical shock to restore a cardiac arrest victim's heartbeat back to normal. The use of publicly accessible AEDs could potentially prevent 100,000 deaths per year. Many sport, recreation, and fitness programs have installed AEDs while several others are considering them. The purpose of this article is to: (1) describe the purpose and function of AEDs; (2) provide recommendations regarding AEDs from leading sport, recreation, and fitness practitioners; (3) provide information on AED trends, training, and certification; (4) identify related legal issues and concerns; (5) provide references regarding AED training and legislation; and (6) provide recommendations for those considering and/or implementing AEDs. With the recent emphasis on publicly accessible AEDs, it appears that sport, recreation, and fitness programs will begin to see more of them. Prudent professionals should stay abreast of the developments, research, and legislation regarding AEDs.

Full textAbstract:
A database server called the Database Management System (DBMS) that relates tables in a database is called the Relational Database Management System (RDBMS). DBMS/RDBMS is a computer program that provides data services for computers or other computer programs. One of the RDBMS type database server (hereinafter referred to as a database server) is MariaDB. The database server is in charge of managing and providing data, so data must always be ready, fast presented, accurate, and safe, it cannot be damaged or even lost. One way to provide this data is to install several database servers using the concept of replication in the Multiple Server Database system. Replication in a cluster server database is a method of installing several database server nodes that allow between node servers to copy each other and distribute data from one node to another database server node, which then synchronizes data between server nodes to maintain data consistency. This study looks for the most optimal number of minimal database server nodes to provide accurate, fast and safe data on the MariaDB Cluster RDBMS. From the results of the replication test from the cluster server database, it can be concluded that the number of 3 (three) node servers can be known to always synchronize and consistency of data between server nodes, so there are 3 (three) nodes of minimum database node with MariaDB RDBMS.

Full textAbstract:
Government intervention in the form of financial incentives is crucial for translating customer choice into a larger market share for solar thermal applications. The lengthy subsidy programs for solar water heaters in Taiwan have expanded the local market. On a remote island (Kinmen County), the area of solar collectors that are installed per 1000 inhabitants is 192.9 square meters. This study investigates a market-driven mechanism in terms of disposable income, household structure, building type and financial viability. The dual subsidy programs appear to have distorted the local market. The cumulative energy savings for solar water heaters that are installed is misleading because the systems are over-designed and there is a high replacement rate (or shorter service period).

Full textAbstract:
Nowadays, antivirus is one of the most popular tools used to protect computer systems. Diverse antivirus vendors are established to protect their customers against malware. However, antivirus is facing some critical problems, such as significant detection windows, vulnerability inside antivirus, and long scanning time. In this paper, we recommend a cloud-based real-time defense mechanism named Skywalker to allow users to safely utilize antivirus without the above problems. After Skywalker is installed in a host, the host does not need to install any antivirus. However, Skywalker guarantees that the host only executes programs that have been verified by a cloud-based scanner, such as VirusTotal. VirusTotal uses 56 antivirus engines to check whether a program is malware. Research shows that the more antivirus engines are used, the more accurate the result is. Because the above scan is performed right before the execution of every program, Skywalker provides 24/7 real-time protection to a system. Besides, Skywalker eliminates the need to spend a lot of time scanning all files in a host. Experimental results show that after a program has been executed once, it takes Skywalker, at most, 0.47091 s to start the program again. Meanwhile, VirusTotal provides a secure protection to client hosts.

Examines the positive and negative sides of distance education in aspects of quality of education and economic efficiency of the distance learning software that are used in the training for the selected training areas/specialties. In the course of the research conducted by the method of questioning students, it was revealed that at the current time, 69.7% of students have none of the programs they need for further direct training of their profession on their home computers. Considering the provision of students with the software they need to study basic subjects, it was found that 24.5% of students have Microsoft Office 2007 or earlier installed on their personal computers (PCs) or laptops, that is, SOFTWARE that is already considered obsolete. Thus, almost every fourth student, when performing practical, laboratory, course work using a software package for working in the office, experiences difficulties.

Thus, almost every fourth student, when performing practical, laboratory, course work using a software package for working in the office, experiences difficulties. Why the computer works even slower and with various failures and failures. Moreover, the specified percentage may also be even higher, since 8.6% of students could not answer what OS they have installed. Studying in the traditional form of training, this lack of hardware and SOFTWARE is eliminated, since in the University’s computer classes, there are PCs that support reliable operation with Windows 10 and Microsoft Office 2010 and are protected from viruses and attacks by installed and constantly updated antivirus programs. The article reveals the problems that affect the quality of students’ education when switching to distance learning. Namely, the absence or non-compliance of Hardware and SOFTWARE for students’ computers and laptops with modern requirements for Hardware and SOFTWARE for performing teachers’ tasks. The author concludes that when switching to full distance education in technical specialties, the state will lose, according to the most optimistic forecasts, from 19.8 to 69.7% of well-prepared students only because their education does not meet modern requirements.

Full textAbstract:
BioXTAS RAWis a graphical-user-interface-based free open-source Python program for reduction and analysis of small-angle X-ray solution scattering (SAXS) data. The software is designed for biological SAXS data and enables creation and plotting of one-dimensional scattering profiles from two-dimensional detector images, standard data operations such as averaging and subtraction and analysis of radius of gyration and molecular weight, and advanced analysis such as calculation of inverse Fourier transforms and envelopes. It also allows easy processing of inline size-exclusion chromatography coupled SAXS data and data deconvolution using the evolving factor analysis method. It provides an alternative to closed-source programs such asPrimusandScÅtterfor primary data analysis. Because it can calibrate, mask and integrate images it also provides an alternative to synchrotron beamline pipelines that scientists can install on their own computers and use both at home and at the beamline.

Full textAbstract:
There are many short-read aligners that can map short reads to a reference genome/sequence, and most of them can directly accept a FASTQ file as the input query file. However, the raw data usually need to be pre-processed. Few software programs specialize in pre-processing raw data generated by a variety of next-generation sequencing (NGS) technologies. Here, we present AUSPP, a Perl script-based pipeline for pre-processing and automatic mapping of NGS short reads. This pipeline encompasses quality control, adaptor trimming, collapsing of reads, structural RNA removal, length selection, read mapping, and normalized wiggle file creation. It facilitates the processing from raw data to genome mapping and is therefore a powerful tool for the steps before meta-analysis. Most importantly, since AUSPP has default processing pipeline settings for many types of NGS data, most of the time, users will simply need to provide the raw data and genome. AUSPP is portable and easy to install, and the source codes are freely available at https://github.com/highlei/AUSPP .

Abstract— Literally embedded systems are defined as equipment that computes a particular job. Embedded Linux System was also developed as a means of education, one of which is ED-255EK Embedded Education Platform, designed to be very practical and consume very low power. ED-255EK is also equipped with a PXA255 processor that is compatible with ARM version 5TE ISA, so it can be used to carry out various kinds of lab work or experiments on embedded systems. The working principle of this tool begins with the configuration of data communication between Fedora Linux and ED-255EK. When the communication goes well, it is downloaded by the ED-255EK system to a laptop or computer that has been installed with the Fedora 9.0 Linux operating system. To take advantage of the ED-255FPGA module, driver module installation is required first, after which the application program is installed. Laptops or computers that have installed the Fedora 9.0 Linux operating system will act as input and output programs making it easier to monitor each module that is being run. The module used is the ARM 1923 Robot Module and Voice Module ED4321.

COVID-19 has spread to various countries and affected many sectors, including education. New challenges arise in universities with study programs related to computer programming, which require a lot of practice. Difficulties encountered when students should setting up the environment needed to carry out programming practices. Furthermore, they should install a text editor called Integrated Development Environment (IDE) to support it. There is various online IDE that supports computer programming. However, students must have an internet connection to use it. After all, many students cannot afford to buy internet quotas to access online learning material during the COVID-19 pandemic. According to these problems, this study compares several online IDEs based on internet data usage and the necessary supporting libraries' availability. In this study, we only compared eleven online IDEs that support the Python programming language, free to access, and do not require logging in. Based on the comparative analysis, three online IDEs have most libraries supported. They are REPL.IT, CODECHEF, and IDEONE. Based on internet data usage, REPL.IT is an online IDE that requires the least transferred data. Moreover, this online IDE also has a user-friendly interface to place the left and right sides' code and output positions. It prevents the user from scrolling to see the results of the code that has been executed. The absence of advertisements also makes this online IDE a more focused appearance. Therefore, REPL.IT is highly recommended for users who have a limited internet quota, primarily to support the learning phase of computer programming during the COVID-19 pandemic.

It is obvious that ICT makes the process of teaching/learning more effective and beneficial whereas the education system starts functioning faster. The development of ICT and the process of globalization determine alteration in the education system as well as in the whole society. The implementation of new technologies in the educational process raises new possibilities for both teacher and learner, enhances educa-tion quality and makes the educational process more versatile. Hence, the object of research is the use of computer-based technologies in the process of teach-ing/learning sciences. Research is aimed at establishing the positions of 1st year students on applying com-puter-based technologies in comprehensive school learning sciences and at disclosing the frequency of us-ing these technologies in the classroom during the lessons on sciences, and also to find out some infor-mation about students` own skills in using computer technologies. Pilot research Student and Computer-Based Technologies was conducted in October – November, 2009. To collect the required data, an anonymous questionnaire was prepared. Research sample consisted of 211 respondents who were 1st year university students (freshmen). To collect the required data, an anonymous questionnaire including four main blocks was prepared. • The level of ability to use computer (in total, 30 parameters were included, for example, ability to use programs and documents, ability to operate fail search system etc.). • The methods of using computers (5 parameters were included, for example, learned during in-formatics classes; during classes in other subjects; during extracurricular activities; helped family members, friends etc.; individual learning). • The evaluation of the frequency of applying computer-based technologies during the classes of sciences (5 parameters were included, for example, the frequency of using a computer projector by the teacher; the frequency of demonstrations done by the teacher, the frequency of applying computer-based technologies by the students for the purpose of practical experimentation; the frequency of communication between students and teachers outside the classroom etc.). • Opinions on applying computer-based technologies during the classes of sciences at school. 20 closed type questions were addressed, for example, using computer-based technologies to make lessons more interesting, to increase motivation, for communication purposes etc. In the majority of cases, the students learn to use computer independently, whereas next comes help provided by friends and family members. The lessons of informatics have a higher impact on the learners from regional centres and female students. The classes on other subjects and extracurricular activities have no significant impact on increasing knowledge of work at computer. It has been established that computer-based technologies are very rarely used during the lessons of other subjects. The teachers relatively fre-quently used computer during the lessons of physics and biology, les frequently - during the classes of chemistry and physics. The teachers of sciences very rarely use computer-based technologies outside the classroom, i.e. for tutoring, giving advice, performing different tasks. The respondents think that using computer-based technologies in the classroom during the lessons of sciences has the highest impact on cog-nitive abilities (knowledge acquisition, self-sufficient studies etc.). However, they do not find important the impact of technologies on motivation for learning, practical use, communication and collaboration between students. Moreover, applying computer-based technologies in the classroom helps with concentration, pre-vents from distracting attention and does not lead to stressful situations, i.e. has no negative impact on the state of health and personal development. The level of ability to use computer (for example, ability to use programs and documents, ability to operate fail search system etc.) Computer knowledge and abilities does not depend on the duration of com-puter usage per day. The best skills are demonstrated in ability to carry out the simple functions of editing of the text, to use search systems and e-mail. The weakest skills, according to respondents, are connected with abilities to create websites, to establish and change parametres of computer programs, and also to instal new computer programs. Some differences depending on the sex of respondents are established also. For example, male students are better in ability to use complex functions of operating systems, than female students. Key words: computer-based technologies, science education, skills, science lessons.

A special place in the methods of surgical treatment of bone fractures is occupied by transosseous osteosynthesis using external fixation devices of various designs.Objective: to analyze the lower jaw exoskeleton in finite element programs.Materials and research methods. During the research, 36 human lower jaws were involved from the museum of the Department of Oper-ative Surgery and Topographic Anatomy of the Volgograd State Medical University. They were scanned in 3D. All obtained images were loaded into a virtual scene reconstruction program. Fractures of the lower jaws in the corner area were modeled, an apparatus for external fixation of the lower jaw exoskeleton was installed, and the chewing load on the lower jaw was simulated. The place of application of the force was an area on a small fragment of a repositioned 3D model of the mandibular bone corresponding to the place of attachment of the masseter muscle. The evaluation of virtual studies was carried out according to the results of the stress-strain states of the bones and apparatus, the schedule of displacements of objects and the results of the analysis of the safety factor.Research results and discussion. In the course of evaluating the virtual placement of the mini-fixator wires of the apparatus for external fixation of the lower jaw exoskeleton, it was revealed that the main load is applied to the mini-fixator wires on a large fragment and the bone in the area of the wires. For the possibility of precise positioning of the osteofixers of the external fixation device, a device for the safe installation of the spokes of the lower jaw exoskeleton was also developed.Conclusion. Thus, on the basis of computer mathematical analysis, it can be argued that the developed design of the apparatus for external fixation of the lower jaw exoskeleton works under conditions of the maxillofacial region, performs reposition and fixation of bone fragments of the lower jaw under conditions of chewing functioning of the restored fracture of the lower jaw.

Background There are lot of books that teachers use in teaching process, but books are still unable to represent difficult view and to enclose 3D features of object. To reduce this lack of information proceeding there can be used computer visualisation in the classrooms. Computer technologies can be essential tools for scientific teachers because of the extensive possibilities to show 3D representations. The teachers do not feel competent in knowledge of modern technology that is why they rarely use them in teaching process-es. Clear computer based visualization helps students to understand difficult concepts and this leads to comprehension in science education. The more concepts and laws of nature they will now the more quali-tative scientific education will be. The article is grounded on visual thinking and genetic structural model of intellect theories. According to these theories all things, if it is possible, should be visualised, because later it helps to create right mental models and perfect comprehension of objects. This research pretends to enclose computer based visualization tools and the mostly visualised objects in chemistry for the reason teachers could use them in chemistry lessons.

AbstractComputers and the Internet have created a revolution in the way astronomy can be communicated to the public. At Sydney Observatory we make full use of these recent developments. In our lecture room a variety of sophisticated computer programs can show, with the help of a projection TV system, the appearance and motion of the sky at any place, date or time. The latest HST images obtained from the Internet can be shown, as can images taken through our own Meade 16 in telescope. This recently installed computer-controlled telescope, with its accurate pointing, is an ideal instrument for a light-polluted site such as ours.

Computers have become very popular for collecting and analyzing data from toxicology studies. Software for this purpose is often written by individuals who may not be completely aware of the idiosyncrasies and peculiarities of toxicology data. This is particularly true of teratology and reproductive toxicology studies that have their own unique terminology whose definition often varies from laboratory to laboratory. Thus, it is essential that each laboratory spend some time in understanding the software that they have installed and subject it to a rigorous validation procedure to ensure that the software is doing the job that it was supposed to do and that the data are being properly collected and stored. A system of data entry and a set of procedures used to validate various programs in our laboratories are described.

The best alternative for reducing citrus production costs is mechanization. Machine vision is a reliable technology for the automatic inspection of fresh fruits and vegetables that can be adapted to harvesting machines. In these, fruits can be inspected before sending them to the packinghouse and machine vision provides important information for subsequent processing and avoids spending further resources in non-marketable fruit. The present work describes a computer vision system installed on a harvesting machine developed jointly by IVIA and a Spanish enterprise. In this machine, hand pickers directly drop the fruit as they collect it, which results in an important increase of productivity. The machine vision system is placed over rollers in order to inspect the produce, and separate those that can be directly sent to the fresh market from those that do not meet minimal quality requirements but can be used by the processing industry, based on color, size and the presence of surface damages. The system was tested under field conditions.

Full textAbstract:
Within the context of the energy crisis in the Western Cape, the Provincial Government and Eskom (the South African power utility) embarked on a retrofit campaign to install 5 million compact fluorescent lamps (CFLs) in a desperate attempt to decrease the generation deficit. There is also increased pressure for investments in new generation capacity, with all options including the Pebble Bed Modular reactor (PBMR), the Open Cycle Gas Turbines (OCGT) as well as renewable resource technologies being pro-posed. Despite all these concerted efforts it is wide-ly regarded that demand-side technologies, with education programs, subsidies and research fund-ing, have greater scope for achieving success as they tackle the root cause rather than the symptom.The light emitting diode (LED) is a new energy efficient option in the lighting sector that has in recent times been deployed extensively by the City of Cape Town’s Transport Network Operations Department. The technology promises superior attributes that include a longer lifespan and higher energy conversion efficiencies, when compared to the traditional incandescents and fluorescents. This paper details the achievements of the LED in its brief history in the local traffic and signals industry as well as its projected impact on the city traffic light department’s future energy and mainte-nance budget. It is then proposed that these mono-chromatic signal LEDs, which is fast evolving into a white LED, holds the best promise in Cape Town as well as the Western Cape’s energy future if adopted for general lighting in the domestic, commercial and industrial market.

Wider exploitation of computer integrated manufacturing (CIM) in shipbuilding is inevitable as yards seek continuing improvements in productivity and quality to sharpen competitiveness. The buzz word CIM has been used in many ways through the years. The correct interpretation may be the integration of all computer systems directly supporting the definition and production of the ship. This comprises CAD and also administrative systems such as planning and material control programs. CIM in this paper is defined as optimal utilization of CAD data and planning data in shop floor production, including feedback to the planning system and accumulation of quality data. The paper defines the state-of-the-art of CIM solutions at shipyards, and outlines a case study of one larger CIM installation. The case presented shows the structure of one installed system, and outlines the experience gained through planning, preparation and installation of the system. The case also includes cost budgets for the installation, including necessary training for planners and operators. Important organizational issues when planning the structure of CIM based production is described in the case. Terms such as Central Work Preparation and Local Work Preparation are introduced. The tasks performed in each area that add value to the CIM data files are described. At the end of the paper, the authors have outlined some future thoughts on further developments of CIM at shipyards. Important issues are, e.g., on-line production simulation systems capable of constantly updating the planning system in order to ensure the highest possible productivity and to support just in time (JIT) philosophies in all areas of the production.

Full textAbstract:
The graphical user interfaces have become one of the most important means in software marketing over the last decades. This phenomenon occurs with particular intensity in relation to simple, non-specialized software. The users of such programs and devices with installed software of that kind are guided in choosing the product by its “look & feel” impression rather than by considering its, usually deeply hidden, technical solutions (the “engine”). This is understandable especially in the context of the development of mobile technologies, which are present in an increasing number of devices for everyday use. The “look” of a computer program is the display generated when a computer runs that program. The “feel” of a computer program is its function, overall purpose and performance (the easiness of use, promptness of operation) which is partly determined by the structure of the program and the sequence of commands it contains . Thus, the look and feel incorporate two aspects of a program for the user: visual and operational.

The article examines two ways to achieve mastery of undergraduate mathematics: face-to- face and digital learning formats. The authors have developed and tested a unique interactive computer-based learning software – few local programs to practice math online, offline or to be installed into an e-course. We focus on different standard problems, such as, finding determinants, solving differential equations, integration by parts, etc. The aim of this study was to investigate what kinds of the activities lead to good learning outcomes. To date, much of the previous research has suggested that students get the benefits of e-learning and b-learning. Yet, there is a general lack of research on outcomes compares the different ways in which students gain knowledge. The results show that the interactive math simulator is one of the effective tools for developing skills to solve standard problems of higher mathematics. There are, however, some math problems to be learn traditionally, with textbook and chalkboard.

Full textAbstract:
A rapid algorithm for forward one‐dimensional modeling is based on the graphical construction of a multi‐layered apparent resistivity curve using an appropriate combination of two‐layered curves. A collection of two‐layered curves is calculated only once for fixed geoelectrical parameters and saved for future use; an arbitrary two‐layered curve within the wide range of the geoelectrical parameters is then obtained by simple interpolation. This method reduces computation time over other fast algorithms by at least one order of magnitude; in addition, it does not produce any significant computation errors in the late stage as do most other methods. A maximum relative error of about 10 to 15 percent may occur at a few points (usually two to three) in the vicinity of the intersection of the two‐layered curves. In most cases, however, this error does not affect the inversion since the relative contributions of these points to an objective function are small. The application of such a rapid forward algorithm allows one to attack the equivalence problem. For this purpose, several starting search points are randomly distributed within a feasible range in the parameter space. The inversion is then begun with the initial guesses for the parameters; several if not all of the minima of the objective function are found within the specified parameter range. To reduce ambiguity of the interpretation, all reasonable solutions are then correlated with available a priori geologic and/or geophysical information. Application of the above technique to real data shows the ability of the algorithm to detect equivalence and, thus, render the interpretation more objective. Both forward and inverse programs have been installed on a portable desktop computer (an IBM-PC compatible). The programs are easy to use and allow interpretation to be carried out in the field.

Full textAbstract:
Wind power has grown popular in past recent years due to environmental issues and the search for alternative energy sources. Thus, the viability for wind power generation projects must be studied in order to attend to the environmental concerns and still be attractive and profitable. Therefore, this article aims to perform a sensitive analysis in order to identify the variables that influence most in the viability of a wind power investment for small size companies in the Brazilian northeast. For this, a stochastic analysis of viability through Monte Carlo Simulation (MCS) will be made and afterwards, Artificial Neural Networks (ANN) models will be applied for the most relevant variables identification. Through the sensitivity, it appears that the most relevant factors in the analysis are the speed of wind, energy tariff and the investment amount. Thus, the viability of the investment is straightly tied to the region where the wind turbine is installed, and the government incentives may allow decreasing in the investment amount for wind power. Based on this, incentives programs for the production of clean energy include cheaper purchase of wind turbines, lower taxing and financing rates, can make wind power more profitable and attractive.

OBJECTIVES/SPECIFIC AIMS: To create the instrument, we employed a modified Delphi approach by conducting a thorough literature review on Leadership to help concretize the relevant constructs, and then usied these extracted constructs as a springboard for the Rockefeller Team Science Educators (TSE’s) to discuss and refine the leadership domain areas, collectively creating domain-specific survey items, and then further discussed and refining the number, grouping, and wording of the items. METHODS/STUDY POPULATION: We piloted the Leadership Survey by having all of the Rockefeller TSEs rate Clinical Scholars. Each item was answered using a six-point Likert scale where a low score indicated poor expression of the specific leadership attribute and a high score represented excellent expression of the specific leadership attribute. RESULTS/ANTICIPATED RESULTS: Means, medians, standard deviations, and ranges of each item were calculated and tabulated. A complete (Pearson) correlation matrix was computed so that the raw inter-item relationships can be observed. For each a priori Domain an equal weighted summary scale was created and tabulated for review. The internal consistency of each a priori scale was assessed by calculating Cronbach’s Alpha (α). Items with low Item to Construct coefficients were candidates for elimination or modification, and overall scales with low’s will undergo further discussion. To challenge our assumptions of the construction and integrity of each domain, we employed exploratory Principal Components Analysis (PCA), followed by orthogonally rotated Factor Analysis (FA). We also forced the PCA / FA analysis to extract the a priori dimensions that allowed us to compare if the empirical and a priori structures match. DISCUSSION/SIGNIFICANCE OF IMPACT: We are partnering with the CTSA programs at Penn and Yale to assess issues of generalizability and scalability. We are working with Vanderbilt to install survey onto REDCap for ease of dissemination. Will continue to assess psychometric properties and refine as we receive more input.

Full textAbstract:
The beginning of digital signal processing took place in the years 1950 to 1954. Using an econometric model, E. A. Robinson in 1951 came up with the method of deconvolution, which he tested on 32 seismic traces. Norbert Wiener, George Wadsworth, Paul Samuelson, and Robert Solow were his advisors. On the basis of this work, the MIT president's office in 1952 set up and sponsored the Geophysical Analysis Group (GAG) in the Department of Geology and Geophysics. GAG was made up of graduate students doing research in digital signal processing. In 1953, a consortium of oil and geophysical companies took over the sponsorship. At first, GAG used the MIT Whirlwind digital computer. In order to do the larger amount of computing required by the consortium, the Computer Service Section of Raytheon Manufacturing Company was enlisted in 1953. The Raytheon people who played key roles were Richard Clippinger, Bernard Dimsdale, and Joseph H. Levin, all of whom had worked on ENIAC, the world's first electronic digital computer. As originally built, ENIAC did not use programs stored in memory as does a modern computer; instead, the programming was done by rewiring the physical components for each new problem. In 1948, Clippinger was responsible for converting ENIAC into the world's first operational stored-program computer. ENIAC had 20 accumulators but no other random access memory (RAM). The programs were stored in the function tables, which acted as programmable read-only memory(PROM). For GAG work in 1953, Raytheon used the British Ferranti Mark 1 computer (which was the commercial version of the Manchester Mark 1 computer, for which Alan Turing played a key role). This computer was installed at the University of Toronto to help in the design of the St. Lawrence Seaway. Raytheon was plagued by frequent breakdowns of the computer but still produced several hundred seismic deconvolutions for the summer GAG meeting in 1953. The consortium was pleased with the geophysical results but was disheartened by the unreliability of the current state of digital technology. As a result, GAG was directed to find analog ways to do deconvolution. Instead, GAG found that all of the analog methods, and in particular, electric frequency filtering, could be done by digital signal processing. In fact, the digital way provided greater accuracy than the analog way. At the spring meeting in 1954, GAG proposed that all analog processing be thrown out and replaced by digital signal processing. Raytheon was at the meeting and offered to obtain or build all the elements required for digital signal processing, from input to output. The conversion to digital was not done at the time. However, that step did happen in the early 1960s, and exploration geophysics has the distinction of being the first science to experience a total digital revolution. Digital processing today provides seismic images of the interior of the Earth so startling that they compare to images of the stars made by the Hubble telescope. (In fact, the digital method of deconvolution first developed in geophysics made possible the digital correction of the lens of the Hubble telescope.)

Full textAbstract:
The complexity of Mixed-Integer Linear Programs (MILPs) increases with the number of nodes in energy system models. An increasing complexity constitutes a high computational load that can limit the scale of the energy system model. Hence, methods are sought to reduce this complexity. In this paper, we present a new 2-Level Approach to MILP energy system models that determines the system design through a combination of continuous and discrete decisions. On the first level, data reduction methods are used to determine the discrete design decisions in a simplified solution space. Those decisions are then fixed, and on the second level the full dataset is used to ex-tract the exact scaling of the chosen technologies. The performance of the new 2-Level Approach is evaluated for a case study of an urban energy system with six buildings and an island system based on a high share of renewable energy technologies. The results of the studies show a high accuracy with respect to the total annual costs, chosen system structure, installed capacities and peak load with the 2-Level Approach compared to the results of a single level optimization. The computational load is thereby reduced by more than one order of magnitude.

It is well known that the response of a rail tank car to exterior heating (e.g., fire engulfment) is significantly affected by the operating characteristics of the pressure relief valve (PRV). If the valve jams or fails in some way, it can lead to a violent vessel rupture; therefore, PRV failure modes and mechanisms must be understood. This paper investigates the studies which have been conducted in the area of PRV technology. The original focus of the paper was to conduct a literature search to find the state-of-the-art for the PRV’s which are presently installed on railway tank cars, highway tankers, and stationary LPG storage vessels. When few papers were found which had concentrated on this particular topic, the authors continued the search by considering both the nuclear power and chemical processing industries, where similar technologies are found. The results of the literature search suggest that the PRV’s currently installed on tank cars and highway tankers are based on designs more than 30 yr old. Controlled fire tests and industry’s maintenance programs suggest that PRV’s could be improved. Most experimental studies of PRV’s have concentrated on flow visualization techniques and have not considered PRV dynamic characteristics. The lack of understanding of valve dynamic characteristics has slowed the development of improved PRV dynamic computer models.
