Bu Researchers Receive Nsf Career Awards

BU Researchers Receive NSF CAREER Awards Prize supports research, education

Winners of the NSF CAREER awards are Lorena Barba (clockwise from top left), Pamela Templer, Michael Smith, Ajay Joshi, Lucy Hutyra, and Ayse Coskun. Barba and Coskun photos by Vernon Doucette. Joshi and Smith photos by Kalman Zabarsky. Templer photo by Melody Komyerov. Hutyra photo courtesy of Lucy Hutyra

The United States, China, Japan, and others are racing to build the first “exascale” computer, a super-machine able to perform as many operations in a second as 50 million laptops. Lorena Barba’s research tackles two parts of this quest: researching the necessary algorithms and software, while pondering how to educate future computer scientists about the technology.

Exascale computing will enable science to improve such things as climate modeling, predicting natural disasters, and simulating proteins essential to life. “The current worldwide race to reach exascale computing is really about maintaining growth in computer performance,” Barba told an interviewer. Noting that a 1944 computer, the Harvard Mark I, was a tortoise at three operations per second, she said ever-faster computing has become essential to society, and educating computational scientists is “crucial for success in exploiting computer performance for scientific discovery.”

CAREER awards recognize “innovative research at the frontiers of science and technology” as well as the winners’ commitment to community service, according to the NSF. That BU collected six awards amid stiff competition “testifies to the breadth and depth of research talent we have here,” says Jean Morrison, BU provost. “We’re all excited to see what these talented researchers are able to achieve through their project awards and wish them the best of luck.”

The other BU winners, besides Lorena Barba, are:

Ayse Coskun, an ENG assistant professor of electrical and computer engineering, is also researching energy efficiency in a type of computing system, so-called 3D stacked systems. “A realizable target for this project in the next decade is a significant reduction in overall energy consumption for computing infrastructure,” his project abstract says.

Lucy Hutyra, a College of Arts & Sciences assistant professor of geography and environment, researches what her abstract calls the understudied effects of urbanization on carbon dioxide emissions, a key contributor to global warming. She’ll map ecosystem changes across an urban-to-rural spectrum and historical land patterns to assess “the carbon consequences of increasing urban lands,” among other things. The research is important to develop policies for environmental protection and food and energy production as humans multiply in urban areas, says the abstract.

Ajay Joshi, an ENG assistant professor of electrical and computer engineering, is researching how to make computing more energy-efficient, in particular by improving silicon-based data-sharing systems within and between computers. The abstract to his research says that with computers’ energy gobbling growing, it’s “absolutely critical to develop energy-efficient solutions for computing systems.”

Michael Smith, an ENG assistant professor of biomedical engineering, studies multicellular cultures to learn about cell mechanics and how cells communicate. “The coordination of multicellular behavior is critical to numerous physiological processes such as morphogenesis”—the development of structural features—“and wound repair,” according to his abstract. His project also seeks to develop a one-hour lesson on cell mechanics for local high school students and a new graduate course on the topic.

Pamela Templer, a CAS assistant professor of biology, is working on the varying effects of climate change in northern American forests. “For example,” her abstract says, “soil warming in summer may increase root growth, but warming in winter may increase the frequency of freeze/thaw cycles and damage plant root systems.”

The NSF, Uncle Sam’s science-incubating agency, has a $7 billion annual budget and funds one-fifth of all federally supported research in American academia. It is the major federal grantor of research money for mathematics and computer science.

Blogging Your Way Up The Career Ladder

It’s funny how people in IT can sometimes be the last to jump onto the most obvious bandwagons.

You surely have heard of blogs, and maybe take a peek at one now and then. It is a new enough phenomenon that spell checking doesn’t even recognize the word ‘blog’. However, IT related blogs are popping up daily. If you have a teenager, they probably have one — whether you know it is another story.

But do you have one? More importantly, should you have one?

If you have built a useful, thoughtful blog history, you could be well positioned to open the door for a fruitful business relationship. If not, you may not even get in the door. You can be sure if you claim to be an expert, you had better have a blog that covers your expertise or the door will be bolted shut.

Like most new trends, the hardest part is getting motivated and figuring out where to begin. So I found Shahid Shah, CEO of Netspective, who has three IT blogs, including HealthCareGuy, where he pontificates about ancient healthcare software and how to effectively apply more modern technologies.

Shah said he got started blogging in 2003 because he found himself sending out the same email about the latest trends or simply saying, ”Hey, have you seen this article?” to his clients. Now his clients know where to go to stay current on health care IT trends, some of them using RSS to easily track his blog. Really Simple Syndication (RSS) is an XML format designed for sharing headlines and Web content. Think of it as a distributable ”What’s New” for a blog that can be easily added to your favorite Web portal, like MyYahoo.

Before you get started, decide on a topic that is near and dear to your heart. Write about what you know — what you do every day. ”Since blogs are quite informal, conversational and can be short, they are quite easy to write,” says Shah. ”I even keep a backlog of ideas that I can post anytime I don’t have something particular to write about.”

Now that you are bursting with ideas to share, you need a place to blog.

To get up and running, Shah suggests creating your own domain. You can more easily start a blog on a community site like chúng tôi but Shah cautions that it has pitfalls. ”Although you own the content copyright, a blogger site will own your links forever — you can’t move them. Whereas having your own domain name provides you with more control.”

According to Shah, it costs about $8 per month with a blog domain hosting service, such as Dreamhost. These services give you access to Web publishing software like WordPress, as well as development tools so developers can customize sites.

Ready to write and write often?

Shah steals from Nike and says ”Just do it!” but contends it’s important to do it consistently. ”I watch my traffic regularly and when I write regularly, my traffic is stable. But if I go away for a few days due to extra workload, the traffic goes down and it takes a few days to come back because the readers aren’t sure when I’ll be back.”

But should you care about your traffic? Shah thinks so.

”I think it’s terribly important to drive traffic and very important to measure it. I run my blogs for credibility and name recognition for my expertise. So, I try and measure my links to other sites and vice-versa. I keep an eye out for what others are saying about me to make sure I’m being helpful and friendly.” It is worth mentioning that Google ad-words for successful, high-traffic blogs can bring in some spending cash or even be quite lucrative.

Although Shah agrees that blogging is an excellent way to augment a resume, he stresses that bloggers must be very careful about what you write.

Stay Professional

”If you’re writing a ‘professional’ blog to help market yourself or build credibility, you need to stay very professional and not get personal with companies or products,” says Shah. This is because finding a job or engaging in business development with a company you happened to slam a year ago has obvious consequences.

Certainly, you should write thought-provoking ideas, but be careful about your tone. ”Honesty in a negative way can get you in trouble,” he adds. ”Honesty in a positive way can gain readership without getting you in trouble. Simply tell your readers the good and the bad without getting personal about a product or company.”

I asked Shah what he would do differently if he was starting a brand new blog.

”I would be even more focused,” he says. ”Try to have a point of view, espouse specific ideas, and give people a reason to come to your site for something they can’t get elsewhere. The more opinionated you are and the more focused you can be on specific industries or topics, the better and more loyal your readership will be.”

Finally, verify that your current employer or client doesn’t have restrictions about blogging publicly and be careful not to post any confidential information. Think how your manager, or worse — legal department — would react to you leaking technology flaws or security holes on a product you are developing.”

You now are ready to jump into the blogosphere, which I think is a word, but my spell checker still doesn’t know it. By showing off your smarts, using common sense, sharing links and simply writing about interesting things, your blog will open doors for you well into the future.

Coded Ui Test Automation Framework Tutorial

A typical software automation Testing requires automation tools like Selenium and QTP. Coded UI is similar to these tools and can be particularly useful for functional tests.

Coded UI Test ( CUIT) uses Visual Studio IDE to write scripts, as the recording can be done using Visual Studio.

In this Coded UI tutorial for beginners, you will learn-

What is Coded UI Test?

Coded UI Test (CUIT) is an automated test that drives applications through its user interface (UI). Hence, the name Coded UI Test (CUIT). This test involves functional testing of the UI controls. It checks the functionality of the whole application, including the user interface. It is also used to automate an existing manual test.

UI Test Architecture

Coded UI Test Features

Coded UI features include

Functional Testing

Generate code in VB/C#

Integrated with ALM story

Build, deploy & test in the lab or as part of a build

Local, remote runs, data collection

Rich Extensibility

Intent-aware recording and resilient playback

Coded UI Test (CUIT) Supported Technologies

With coded UI, an application which has UI (User Interface) can be easily tested. The application can be either window based or web based.

Coded UI supports technologies like

Window based desktop applications

Web Services (SOAP, ASPX, etc.)

Window phone applications

WPF (Windows Presentation Foundation)

Web applications (HTML, Silverlight, HTML5)

Why use coded UI for Test Automation

The reason why coded UI for test automation is preferred

Developers and Software Testers can collaborate effectively using the same tools/language.

It supports both web as well as Windows projects.

The element identification mechanism is a great feature in Coded UI. Also, it supports synchronization

The Playback Engine supports features such as ‘WaitForControlExist’ , ‘WaitForReadyLevel’, etc

With the help of ‘Tests Agents,’ automation tests can be run on remote machines

Automation teams can develop sophisticated tests, using coded UI with a layered framework

Software testers can capture exceptions and record the result effectively utilizing log4net.dll

Coded UI tool supports descriptive programming. It allows software testers to automate scenarios based on object properties

It supports AJAX controls.

How to Create Coded UI Tests (CUIT)

To create coded UI tests you can do it in following ways.

Generating from an Existing Action Recording ( converting from manual test recording)

Creating a new coded UI test from scratch

Writing code from scratch

Contents of a Coded UI Test

When you create a coded UI test, the coded UI test builder creates a Map. This includes UI under test, test methods, parameters, assertions, etc. For each test, it also creates a class file.

File Content Editable

UIMap.Designer.cs Declaration section UIMap Class Methods Properties No

UIMap.cs UIMap class (partial) Yes

CodedUITest1.cs CodeUITest1 class Methods Properties Yes

UIMap.uitest The XML map of the UI for the test. It is edited only through UI Map editor No

chúng tôi : The designer contains the code view of the UIMap. It is generated when a tester records some UI interaction or when some objects are added manually to the UIMap.

chúng tôi : Any modification or customization done to the UIMap is stored in this file. Initially, this file will be blank and can be populated later on. If modifications are directly made to the chúng tôi file, make sure it is not recorded otherwise all changes will be lost.

chúng tôi : This file contains coded UI test class, test methods, assertion invocation and method invocation. All assertion and methods are by default invoked from this file.

UIMap.uitest: It is an XML representation of the UIMap class. It includes windows, controls, properties, methods, actions and assertions. It is edited only through UI Map editor

Next in this Coded UI tutorial, we will learn how to perform Coded UI automation test.

How to Perform Coded UI Test

Coded UI has two different ways to conduct a test for your application.

Coded UI Record and Playback or

Coded UI Hand coding

You have to follow the following step to perform Coded UI testing,

Create a CodedUI test project

Add a coded UI test file

Record a sequence of actions

Verify the values in UI fields such as text boxes

View the generated test code

Add more actions and assertions

Edit the details of the test activities and the assertions

Run the test

Best Practices for Coded UI Test (CUIT)

Here are some best practices for a Coded UI test automation framework:

Use the Coded UI automation Test Builder whenever possible

Try not to modify the chúng tôi file directly. Otherwise, the changes you made to the file will be overwritten

Create your test as a sequence of recorded methods

Each recorded method should act on a single page, form or dialog box. Also, create a new test method for each new form, page or dialog box

When you create a method, instead of the default name use a meaningful method name. A meaningful name helps identify the purpose of the method

If possible, limit each recorded method to less than 10 actions. This approach makes it easier to replace a method if the UI changes.

To create assertion use CodedUI test builder. It automatically adds an assertion method to the chúng tôi file.

Re-record the test methods/ assertion methods, if the user interfaces changes or re-records the affected sections of an existing test method.

If you are directly coding with the API, use the methods and properties in the classes created in the chúng tôi file. These classes will make your work more reliable and easier, and will help you to be more productive.

Comparison of Coded UI Test Vs Selenium Vs QTP

Below is the comparison table of Coded UI Vs Selenium Vs QTP:

Selenium does not support any WPF as well as Windows applications

Visual Studio CodedUI supports the Window store application testing as well as Window Phone application testing. No other tools support this.

Test complete does support Window Application but requires a plugin to be installed.

Comparison of Coded UI Test Vs Selenium Vs QTP

Summary:

Automated tests that drive your application through its user interface (UI) are known as CodedUI tests (CUITs).

Coded UI test automation framework supports technologies like Web Services, Window phone applications, Web applications, etc.

Coded UI Testing allows developers and Software testers to collaborate effectively using the same tools/language

Contents or a file created while using CodedUI includes

What Is Sap Security? Complete Tutorial

In this SAP Security tutorial for beginners, we will learn about SAP Security basic concepts.

What is SAP Security?

SAP Security is a balancing act for protecting the SAP data and applications from unauthorized use and access. SAP offers different tools, processes and measures for security check to protect these data. SAP security helps to ensure that users can only use the functionality of SAP which is a part of their job.

SAP Systems contain very sensitive and confidential data of their clientele and businesses. Hence, there is a need for a regular audit of an SAP computer system to check its security and data integrity.

For instance, an employee in a warehouse who is responsible for creating a purchase order shall not approve a rightful purchase order or otherwise he may create and approve as many purchase order without any use.

In such scenario, the purchase order approval should be controlled by a higher authority which is a standard security feature.

Next in this SAP Security for beginners tutorial, we will learn about various Security concepts in SAP.

Security Concepts for SAP

Below are the main Security Concepts in SAP:

1. STAD Data

Transaction codes are the front door to get the access to SAP’s functionality. STAD data provide security against unauthorized transaction access. Does it keep a record of information like who accessed certain critical functionality? And when? STAD data can be used to monitor, analyze, audit and maintain the security concept.

2. SAP Cryptographic library

SAP Cryptographic Library is the default encryption product delivery by SAP. It is used for providing Secure Network Communication (SNC) between various SAP server components. For front-end components, you need to buy an SNC certified partner product.

3. Internet Transaction Server (ITS) Security

To make SAP system application available for access from a web browser, a middleware component called Internet Transaction Server (ITS) is used. The ITS architecture has many built-in security features, such as to run the Wgate and Agate on separate hosts.

4. Network Basics (SAPRouter, Firewalls and DMZ, Network Ports)

The basic security tools that SAP uses are Firewalls & DMZ, Network Ports, SAPRouter, etc. A firewall is a system of software and hardware components which define the connections that should pass back and forth between communication partners. SAP Web dispatcher and SAPRouter are examples of application level gateways that you can use for filtering SAP network traffic.

5. Web-AS Security (Load Balancing, SSL, Enterprise Portal Security)

SSL (Secure Socket Layer), is a standard security technology for establishing an encrypted link between a server and client. With SSL you can authenticate the communication partners(server & client), by determining the variables of the encryption.

With sap cyber security, both partners are authenticated. The data transferred between the server and client will be protected so any manipulation in the data will be detected. In addition to that data transferred between the client and server is also encrypted. Enterprise portal security guide can be helpful to secure the system by following their guidelines.

6. Single Sign-On

The SAP single sign-on function enables you to configure same user credentials to access multiple SAP systems. It helps to reduce administrative costs and security risk associated with maintaining multiple user credentials. It ensures confidentiality through encryption during data transmission.

7. AIS (Audit Information System)

AIS or Audit Information System is an auditing tool that you can use to analyze security aspects of your SAP system in detail. AIS is designed for business audits and systems audits. AI presents its information in the Audit InfoStructure.

Next in this SAP Security tutorial, we will learn about SAP security for mobile apps.

SAP Security for Mobile SAP Apps

SAP applications are now available on mobile with an increase in the mobile users. But this exposure is a potential threat. The biggest threat for an SAP app is the risk of an employee losing important data of customers.

The good thing about mobile SAP is that most mobile devices are enabled with remote wipe capabilities. And many of the CRM- related functions that organizations are looking to mobilize are cloud-based, which means the confidential data does not reside on the device itself.

Some of the popular mobile SAP security providers are SAP Afaria, SAP Netweaver Gateway, SAP Mobile Academy and SAP Hana cloud.

Next in this SAP Security for beginners tutorial, we will learn about best practices for SAP security.

SAP Security Best Practices Checklist

Network settings and landscape architecture assessment

OS security assessment where SAP is deployed

DBMS security assessment.

SAP NetWeaver security assessment

Internal assessment of access control

Assessment of SAP components like SAP Gateway, SAP Messenger Server, SAP Portal, SAP Router, SAP GUI

Change and transport procedure assessment

Assessment of compliance with SAP, ISACA, DSAG, OWASP standards

Summary

SAP Security is a balancing act for protecting the SAP data and applications from unauthorized use and access.

What Are Various Path Elements In Javafx?

The javafx.scene.shape package provides classes using which you can draw various 2D shapes, but these are just primitive shapes like line, circle, polygon, and ellipse, etc… Therefore, if you want to draw complex custom shapes you need to use the Path class.

The Path Class

The Path class represents the geometrical outline of a shape using this class you can draw your custom path.

To draw a custom path JavaFX provides various path elements and, all these are available as classes in the javafx.scene.shape package.

LineTo − This is class represents the path element line. It helps you to draw a straight line from the current coordinates to the specified (new) coordinates.

HlineTo − This is class represents the path element horizontal line. It helps you to draw a horizontal line form the current coordinates to the specified (new) coordinates.

VLineTo − This is class represents the path element vertical line. It helps you to draw a vertical line from the current coordinates to the specified (new) coordinates.

QuadCurveTo − This is class represents the path element quadratic curve. It helps you to draw a quadratic curve form the current coordinates to the specified (new) coordinates.

CubicCurveTo − This is class represents the path element cubic curve. It helps you to draw a cubic curve form the current coordinates to the specified (new) coordinates.

ArcTo − This is class represents the path element arc. It helps you to draw an arc from the current coordinates to the specified (new) coordinates.

MoveTo − Using this class you can move the path from the current coordinates to new coordinates.

Creating a path using the path elements

The Path class contains an observable list which holds the path elements of the current path. Therefore to draw a path −

Instantiate the required PathElement classes.

Set the properties of each path using the setter methods or, pass them as arguments to the constructor.

Instantiate the Path class.

Get the observable list object of the above-created Path using the getElements() method.

Add all the path element objects to the observable list in the desired order using add() or, addAll() methods.

Finally, add the path to the Group object.

Note − You can also pass the path elements to the constructor of the Path class.

Example

Following JavaFX example creates a path using the LineTo path element −

import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.stage.Stage; import javafx.scene.shape.LineTo; import javafx.scene.shape.MoveTo; import javafx.scene.shape.Path; public class PathElementsExample extends Application {    public void start(Stage stage) {             MoveTo moveTo = new MoveTo(208, 71);       LineTo line1 = new LineTo(421, 161);       LineTo line2 = new LineTo(226,232);       LineTo line3 = new LineTo(332,52);       LineTo line4 = new LineTo(369, 250);       LineTo line5 = new LineTo(208, 71);             Path path = new Path(moveTo, line1, line2, line3, line4, line5);       path.setFill(Color.DARKCYAN);       path.setStrokeWidth(8.0);       path.setStroke(Color.DARKSLATEGREY);             Group root = new Group(path);       Scene scene = new Scene(root, 595, 300, Color.BEIGE);       stage.setTitle("Drawing an arc through a path");       stage.setScene(scene);       stage.show();    }    public static void main(String args[]){       launch(args);    }
