The monitoring of Controller Area Network (CAN) data traffic comes usually with a hefty price tag. First, you need a CAN hardware interface to make your PC compatible to CAN. The industry offers PC interfaces in the range from under $100 up to roughly $600 depending on the form factor (PCI, ISA, USB gateways etc.).

Secondly, you need the CAN monitoring (Analyzer) software and it seems that only the sky is the limit in terms of pricing. There are high-end software packages whose prices are definitely justified for engineers, especially in the automobile industry, who are in need of all possible features to analyze and diagnose CAN messages in every detail.

However, the vast majority of engineers involved with CAN development would be satisfied with a mere monitoring tool to display and even record and replay CAN messages on the screen. esd elelectronics, Inc. (http://www.esd-electronics-usa.com) provides such a tool for their CAN hardware interfaces as integral part of their driver plus software development package and, after all, it is free of cost.

The reasoning is esd electronics, Inc. as a specialist for CAN hardware interfaces has the awareness that software is the mandatory vehicle inselling the hardware. This is in contrast to other businesses, especially those providing sophisticated CAN analyzing programs, who need hardware to sell their software.

The esd software development kit (SDK) includes a suite of tools such as:

• CANreal to display and record CAN message frames
• CANplot to display of CAN data in form of graphs
• CANrepro to replay pre-recorded CAN messages
• CANscript, a Python scripting tool
• COBview to analyze and diagnose CANopen nodes

An SAE J1939 add-on module is in preparation.

General Updates

The summer saw some significant upgrades to our alliance partner programs. The interfaces for Aspen PLUS, Aspen HYSYS and SimSci’s ProII were all updated. The release of those products are determined by the respective partners. This was not an easy undertaking.  As a results we have skipped several version numbers for the Analyzer and ESP lines of the software. The new releases will be Analyzers 3.0.10 and ESP 8.1.10.

Databank updates

It has been a while since the last update to the databanks. For the new releases of ESP and the Analyzers we have updated the database. Please review the release notes for the databanks to see what has changed.

Analyzer Updates

There will be some minor updates for Analyzer 3.0.  The next build is scheduled to be 3.0.10 due sometime in September.  We did discover that some older version 2.0 files did not open correctly in 3.0.  The issues were twofold, the first being that some new arrays introduced in later versions of 2.0 were not set up in the earlier versions. When opened in 3.0 these missing arrays caused a crash.  Second, some models are automatically rebuilt when opening the file, there were some timing issues that caused the older 2.0 files to crash when opening in 3.0. This was all corrected for the upcoming build.

Occasionally the Analyzers corrupted a file when it saved. We found the cause and have added protections to prevent this from happening. We also found some solver problems that will be addressed under the ESP section below.

Please check the release notes for all the updates for this version of the Analyzers.

ESP Updates

ESP is getting some minor updates. We found a problem with rebuilding model definition files (MDL) from existing MOD files. The automatic re-builder did not honor the existing thermodynamic framework.  The new MDL file was always defaulted to the Aqueous Framework.  This was corrected for build 8.1.10 (note, we are skipping builds 8.1.7, 8.1.8 and 8.1.9 to keep pace with the OLI Anlyzers whose current build is 3.0.8)

A bug was detected that in MSE 2nd liquid cases the initializer occasionally would consider a single phase a a pure phase and not calculate an equilibrium condition. This was corrected

Problems were found in the API-8 code for pseudocomponents and assays. Certain names did not work properly.

The extended thermodynamic property reports for Gibb’s Free Energy and Entropy have been written to separate files for ESP. The column headings for Entropy were misleading which has now been cleared up.

MSE: Major issue was detected with ions in the 2nd liquid phase. They were not properly accounted for in the mass balance. This could lead to numerical instability when the ion concentrations were large. This was corrected.

MSE Bubble point prediction calculations for 2nd liquid phase cases were improved.

Please check the release notes for all the updates to ESP 8.1.10

CSP

CSP is been largely superseded by the Corrosion Analyzer but some of the code is still shared.

Stability diagrams had lost the ability to display the natural pH of the solution. This feature was restored

Stability diagrams for MSE required a small amount of H2O to be present in the calculation to calculate the PH of the solution. We now add 1.0E-12 * total stream amount (in moles)

DynaChem

DynaChem, a program that was almost lost to antiquity, has seen a major round of updates in the recent months.  A problem with vectored input was discovered. Vectored input field are allowed on many operations to schedule events. This did not properly work for valves when scheduling a valve to close. The time of the closed valve event was not recorded which made the plot routine skip points. This was updated to work properly

A problem was found in PIPE units.  Adiabatic calculations were still performed even if discharge temperatures were specified. This caused unexpected temperatures. This was corrected.

We upgraded the numbering system in DynaChem.  Previously you could only have numbers up to 99 for any unit, node, valve, control loop, etc. Now the number has been increased to 999,999. Internally the numbers are remapped to the original set of numbers.

Training

I have added some extensive training and help documentation to the OLI Support website. Here is a brief list of what has been updated:

1. How to import data from Excel in to the Extreme Value Statistics (EVS) program.
2. OLI Security Issues
   • Security Test Program
   • Serial Numbers
   • Hardlock devices
   • Invalid Keys
   • Missing drivers
   • Static Security Provider Errors
   • Registry Settings
   • Install and use Network Security
3. Getting Started with Aspen PLUS and OLI
4. Getting Started with OLI Studio 3.0
   • Units Manager
5. Getting Started with ESP 8.1

As you can see I have made a good start but there is much more to do.

Slow updates

I have been slow in posting some updates. I was on a mini vacation to attend a wedding in Lansing, Michigan and then underwent some minor surgery. It was all planned and I am doing much better. I will post more frequently now that I am back to work.

Regards,

Jim Berthold

Clinical hematology analyzer analysis is one of the oldest and most important sectors of clinical laboratory analysis. The hematology instrument and reagent market is centered around a group of instruments called hematology analyzers. The term clinical hematology analyzer usually refers to an automated instrument for determining the presence, number and type of cellular elements in easily collected body fluids, such as blood. However, it is not necessarily limited to these determinations. The hematology analysis always includes determination of non-cellular parameters in blood, such as hemoglobin and hematocrit. Other closely related areas of clinical interest are coagulation and flow cytometry. In fact, traditional specialization barriers, such as microbiology, hematology, blood banking, immunology and even anatomical pathology are rapidly fading both operationally and instrumentally. But for the sake of defining the subject to a reasonable size, the more traditional scope of clinical hematology analyzer will be the focus of this examination. The purpose of this Publications report is to describe the specific segments of the global clinical hematology analyzer instrumentation and reagent marketplace. The review covers those segments that are highly active in terms of innovation and growth. Specifically, this study examines the markets for small-lab, as well as highly-automated large-lab, platforms and accessory equipment, such as reagents, supplies and add-on equipment from original equipment manufacturers.

Botnet traffic bounds back 90% within 48 hours of ISP shutdown

Cutwail is one of the largest botnets running today, producing 15% – 20% of all spam, including malicious sites, phishing sites and fake antivirus sites. With most of its operations running from Latvian ISP, Real Host, the ISP was shut down by upstream providers. During a 48 hour time period spam dropped by 38% and cutwail’s botnet activity dropped by 90%. After the 48 hour period, cutwail’s activity was at nearly the pre ISP-shutdown levels. After the November 2008 shutdown of McColo Web Hosting it took several weeks for botnet activity to reach its previous levels of activity.

Message from Hackers: Enjoy The Summer Break Because Winter Attacks Will Be Harsh

According to a poll taken at last month’s Defcon17 less than 25% of hackers are malicious. Of those 81% are more active during the winter months with 56% saying Christmas is the optimal time and 25% saying New Years Eve is the most optimal day for hacking. 52% say weekday nights are when most of their hacking is done. Over 30% hack during business hours while only 15% hack on the weekends.

MS phishing filter blacklists everything

All sites ending with “.uk.com” have been blocked by Microsoft’s SmartScreen Filter. The filter is built into IE7 and IE8. It is unclear why such blockage occurred other than human error. This points to the scenario that filtering, no matter how good is not an exact science.

PCI Council Releases Recommendations For Preventing Card-Skimming Attacks

Credit card skimming is becoming the a popular way for credit and debit card account numbers to be stolen by cybercriminals. Devices are rigged to obtain the data, whether the rigging occurs after installation or before the device leaves the manufacturer. If credit cards were cryptographic devices, the threat would disappear.

China Forecasts Spread of Chinese Domain Names

CNNIC, the official registry for China’s ccTLD, .CN, announced that it is moving ahead with the deployment of .CN using both simplified and complex Chinese characters. Government organizations are already moving forward with the acquisition of the localized TLDs. Some are already in use within China, however most advertising within China utilizes the traditional Latin/ASCII character set for their URLs. People and organizations who already have a .CN name will automatically receive the localized version in both simplified and complex Chinese. Not only will this prevent legal issues over name ownership, it will also prevent phishing using such names because one who owns a simplified Chinese version does not need to worry about a phisher using the same name with the complex Chinese version. At ICANN’s October conference China hopes to push ICANN to an agreement on IDNs so the simplified and complex versions of Chinese second and top level domains can migrate to DNS.

As of the end of June China had more than 338 million Internet users; the largest of any country.

Obama’s FCC to enforce ‘net neutrality’

FCC chairman, Genachowski said that net neutrality will be supported and attempts to violate its tenets will be sought. It is the intent of the Obama administration to ensure the Internet is free of increased user fees due to heavy traffic and slow downloads. To assist in this endeavor a member of Congress has introduced a bill aimed at enforcing net neutrality legislation that guards against discriminatory practices by network operators. This is going on at the time Comcast is in a legal battle with the FCC whereby Comcast is challenging the FCC’s authority for penalizing Comcast for limiting web traffic to its consumers.

Dutch ISP builds dike around ‘Net, throttle non-HTTP traffic

Even as ISPs in countries such as Canada and throughout Europe throttle specific protocols at certain times of the day, a Dutch ISP is making their throttling efforts easy to understand. ALL non-HTTP traffic will be throttled back to 1/3rd the bandwidth speed, every day from noon to midnight. The thinking is websites are fine, however VoIP, P2P and FTP shall have second priority as the Web is not and shall not become a rich media delivery service.

Notorious hacker Analyzer pleads guilty on credit card scam

Known for breaking into NASA’s systems Ehud Tenenbaum, known as “Analyzer”, has pleaded guilty to US authorities for credit card fraud that cost US banks as much as $10 million.

What would normally carry a 25 year prison sentence will most likely be reduced due to his cooperation with authorities.

Click here for more information.

Ehud Tenenbaum, the Israeli hacker known as ‘The Analyzer’, has entered a guilty plea to a charge of bank card fraud in a US court.
Tenenbaum was detained in Canada in an investigation relating to a Canadian card fraud case before being extradited to the US to face further charges. The US charges pertained to hacking attacks on banks and card processing companies which purportedly netted some US$10 million for Tenenbaum and his accomplices (though it is currently unclear how the US authorities arrived at this figure).
US prosecutors alleged in their affidavit that Tenenbaum, 29, was at the centre of a global ‘PIN cashout’ conspiracy wherein teams of ‘cashers’ in numerous countries would burn stolen bank details to blank cards and withdraw cash from ATMs, sending a cut back to Tenenbaum. However, in what is almost certain to be a plea-bargain arrangement, Tenenbaum has pleaded guilty to a single count of access-device fraud, with other charges apparently dropped.
The US authorities have likely been keen to get their hands on Tenenbaum after he broke into Pentagon and NASA computers back in 1998 and escaped with probation and a fine from an Israeli court rather than facing prosecution in the US.

Okay, after my last post about whether I should get back to rebuilding my netflow collector, Styx….. I finally made a decision.  I’m going to push on.

The main reason is because there really isn’t anything out there to give you the data you want.  Yes, there are some really great products out there, but you are limited to the graphs and data exports that the programming company *want* you to see.

Styx is different.  Yes, it will have the same kind of graphs, but puts you back in the driver’s seat.  The way I see it….. if you are saavy enough to know that you need netflow data, then you are competent enough to know what data you want to see.

Styx has an OLAP engine that will allow you to drill-down to see the data you need.  You can do all the “data-mining” you want.  Of course, I’m still building it, so it’s more like a fantasy than real life… but it IS in progress:  http://styx.javaforge.com

It’s built on SQL, so you can use your favorite reporting package.  Of course, on high-traffic networks, you could be analyzing millions of records, so to be efficient is a major challenge.  But, one that I’m willing to overcome.

Thanks to everyone for your comments on my previous post, as well as, the many emails I received.  I appreciate your feedback, advice, and confidence in me.

Once this package is available to use, I would love to have your help in letting me know what’s most important to you.

Until then, I will continue coding……. java-style!!

Cheers!

While working on the Density overall re-design I was working extensively on the audio engine as well but just for one single reason: The one thing I was missing in the original design was to have some more “responsive” gain riding possibilities but without the usual tradeoff of introducing more distortion or compromising the transparency. And (unsurprisingly) that turned out to be not that easy.

Developers friend: the oscilloscope

Fortunately, there are a couple of gadgets in the audio developers toolbox which can tremendously help in getting the things right or to avoid (time consuming) audio listening tests in the early development stage. The oscilloscope e.g. is a good tool to investigate a certain attack and release curve behaviour or to perform tests with automatic leveling circuits just to name the two. This is mostly performed on periodic input signals like raw basic waveforms. While re-designing the audio core of Density I did a lot of experiments with that and even checked some weird and funny approaches to compression which had lead to some interesting insights here and there while working towards the final circuit.

A CPU cycle measurement tool

At the end of the day not everything which looks promising in the oscillator actually does sound necessarily good or, in other cases, the computational costs of that algorithm is simply way off. The latter one can easily checked with CPU cycle sort of tools which provides instant feedback on how many CPU cycles a certain algorithm actually consumes or which performance optimzation gains more speed. I’ve used such tools and methods quiet a lot during the technical design of the mkII version and that way I was able to introduce some new algorithms with higher precision and resolution but at lower computational costs (compared to the original design). In general this is better already been finished during the design phase opposed to upon the end of development where this can cause more impact (overall redesign or so) and therefore potentially can waste a lot of development time. Further Assembler code tuning on the other side is better be done to the end of development for the sake of programmers efficiency.

A pure second order harmonic in the analyzer

Christian Buddes audio plug-in analyzer is another excellent tool when you already have managed to get your algorithms compiled into a VST dll-file. It’s really usefull on judging frequency or harmonic spectrum issues like intermodulation distortion or the compressors transfer curve and things alike. However, it cannot see all things and sometimes even weird stuff or nothing is showing up though it normally should do so. This can be the case when e.g. measured algorithms just work on or behind transients, on mid/side encoded signals or just works differently along the entire frequency spectrum. In the plot above everything is ok and it shows an algorithms effect where just a pure second order harmonic is produced (oversampled). In DensitymkII the compression algorithm itself is capable of generating a pleasant second order harmonic during the compression duty cycle. This replaces the “phat” mode of the previous Density version and is inherently active.

10kHz sinus signal pre and post compressor

If the developed plug-in now properly loads into a host, another common technique for measuring the dynamic behaviour of such an audio plug-in is to load the compiled plug-in into it so someone can apply special test signals on it. Continous sinus based signals at different frequencies (e.g. 3kHz, 10kHz or even rather low frequencies for measuring bass response) at different levels over time are typically used. The outcoming overall curves are then compared to the original test signals or to some reference curves of other devices or so. This was a lifesaver during the beta test stage of DensitymkII where some subtle discontinuities in the release curve were spotted (caused by a malfunctioning program dependency) and so it could be finally tracked down. The way program dependency in the mkII is actually implemented now is a major part of the unobtrusive compression action and it offers both now: strict peak compression and relaxed and punchy sound.

An audio wave player

Normally, one would increase the number of audio listening tests along the progress of development over time and therefore switch over to separate testbeds to do so. In the development framework I’m currently using, one is able to just load audio files into a wave player and to hear it passing through that algorithm which is currently under developement. Thanks to instant re-compile there is no real lag when re-triggering audio and so you can hear and judge the code changes instantaneously during development – what a time saver!

Many thanks to the Synthmaker community and Christian B. for providing all those usefull tools!

OLI Analyzer 3.0.7 is launched

Well we actually went several weeks without an upgrade to the the OLI Analyzers. We did find some unusual bugs.  The release notes for the Analyzers explain in more detail what we found. In brief

• When the Gibb’s energy calculation was enabled, the program crashed. We found a mis-alignment of an array that was fixed
• Network installations got confused when entering the name or IP address of the server. An erroneous error message was displayed. This was cleaned up.
• The ability edit the toolbar and add custom buttons was re-enabled. Somehow we managed to turn it off.
• Users could enter assay and pseudo-component names with special characters such as the plus “+” sign. This caused the internal model generator all kinds of problems. The code was updated to prevent special characters from being entered. Only the characters A-Z (both upper and lower case), 0 – 9 and the underscore “_” are allowed.
• Somehow we removed most of the plot variables for the mix calculations. We have added them back to the plot program.
• Pass-Through models (models created in ESP or the Chemistry Wizard) failed if they were created with later versions of ESP (8.0 or later) This was because of a change in date format in the DBS file. This was corrected
• The cancel button now works to stop a calculation
• We added a feature to the tree-view. If you right-click on an icon you can change the view to names instead of icons. This reduces the real estate consumed and makes for a more compact view. This also works for the object library.
• The plot option dialog allowed you to display more than 5 dominant species but the internal code limited it to 5. This check has been expanded to allow you to truly display the desired number of dominant species.
• The assay distillation column headings were incorrect. They now read the correct value for the type of assay data being used.
• Occasionally a stability diagram crashed with the error message “Insufficient Virtual Memory.” This was caused by an error in the Fortran code. The code was updated to reduce the amount of memory being consumed.
• The database continues to grow. New redox subsystems are present and the code was updated to allow them to be displayed.
• We added a feature to save the layout of the definition grid. Some users always need to see a particular part of the grid (Additional Stream Parameters for example). Right-clicking the grid allows you to save the layout.
• The new HTML format reports in surveys did not allow you to cut and paste the data into a new object such as Microsoft Word. We have enabled this feature once again.
• The units manager was updated to allow English unit sets for custom units.
• The solver was updated for odd cases where the 2nd liquid phase was enabled but it did not form. This gave inconsistent results in some cases.

How is pH calculated in a model that does not have any hydrogen ions?

This is a question that is asked frequently. So much that I have written a guide that explains the hydronium ion conversion for standard pH calculations using the OLI software. This is for those users who need to make sure that OLI is on the up-and-up.  Here is a direct link to the document on the OLI support website.
