Net Sniffing

It’s been a while since, I got a chance to make a post. One of the primary reasons that we had to shift focus was on intrusion detection. What was really shocking was attempts by government agencies to sniff on our VPN systems. Real time intrusion detection systems helped us log every attempt into our local systems. I was personally perplexed by knowing that the US Navy wishes to talk to our VPN network. Here is an extract:

13:44:55.968501 IP (tos 0x20, ttl 51, id 30982, offset 0, flags [none], proto UDP (17), length 170)
    ************** > ***.local.53687: [udp sum ok] 34105 q: PTR? 1/3/0 PTR tock.usno.navy.mil. ns: 41.5.192.in-addr.arpa. NS charon.nofs.navy.mil., 41.5.192.in-addr.arpa. NS psyche.usno.navy.mil., 41.5.192.in-addr.arpa. NS charon.usno.navy.mil. (142)

While I was in US, such attempts into personal systems were often made. Our systems have more than 100MB of logs from such systems. I think this goes on with every immigrant in the US. These attempts are troubling considering the email services etc. Secure and safe communication is essential and foremost for any business to succeed.

This took most of our time. We have to dedicate more time securing our systems. Mostly in the US privacy violation has become a way of life. For new immigrants, the competition in business is more stringent in terms of succeeding. Often people who are already settled have better connections and resources to the local network. The problem is with, this information about company’s email communication etc. being passed on to other competitors.

Cloud Stack for Spatial Data at Equinox Logic

Equinox Logic is coming up with its own spatial cloud stack based on open source for providing large amount of spatial data solutions to its clients. We have updated nearly 30 linux based virtual machines in order to serve our data on the web. The cluster would significantly enhance our capabilities in serving the data across several clients and reduce dependancies as well as restrictions with the current servers.
Our team already utilizes these capabilities in order to edit the data over the intranet. Equinox Logic is unveiling the capabilities of the open stack. Results of our environmental and climate change and transportation modeling are already being published over the intranet. The amount of Spatial data related to environmental, climate change or transportation modeling is quite significant. The key is to manage this data wisely, in order to provide faster and better solutions to our clients.

Spatial Analysis- Highest Temperature variation across India

Part of the problem to understanding the climate change input factors, temperature variation across India was analyzed by Equinox Logic Pvt. Ltd. Our consultants had a chance to explore, the places with the highest temperature variation in terms of the minimum and the maximum seasonal temperature variation that was experienced for each city over the past 100 years.

Temperature differences across India in the past century till 200

Highest Seasonal Temperature variation for 24 cities across India in the past 100 years. Part of climate change modeling. Integration into environmental models.

We are presenting herewith the temperature variation across India for 24 cities. Under natural conditions even some cities across India, have experienced extreme, temperature variation. Man-made factors have contributed to this variation as well. Our consultants have studied the emission pattern changes for GHG’s across cities in India. Part of preparing the environmental model for cities, was also to collect, analyze, interpret pattern changes and investigate as per the quantitative variations.

Part of preparing the environmental model special attention is being given to how accurate the data is. Our consultants are also in the process of integrating with the existing environmental models. We shall throw more light as we delve into refining the model further.

Rainfall and Minimum Temperature Distribution Across India

Equinox Logic Pvt. Ltd. has been investigating into the climate change occurrences across India. Part of the process of development of the climate change modeling was to analyze the changes in the rainfall pattern as well as the lowest temperatures that have occurred.
One of the major tasks was to arrange the data in required format to visualize spatially.climate change temperature analysis When we considered temperature change, we mean the relative monthly temperature change. For. eg: if the temperature for January in 1901 was 24.0 degrees celcius , which is compared against, the temperature occurence in January of a particular year. Interestingly we are presenting only 24 cities across India in this blog with regards to the temperature and the rainfall distribution for the past 100 years.
Similar analysis was done, on the rainfall distribution patterns across India for the past 100 years until 2000. Why are we not considering data after 2000? There is another component which was analyzed and should be considered. In order to have consistency, it was important to adhere to this format.
With regards to the temperature distribution, interesting changes were observed, for several states and cities across India. Each city was analyzed for several components towards the climate change model.

Rainfall Distribution

The highest rainfall distribution(green gradients) for the 24 cities is also presented herewith. Rainfall data for several cities was observed, several changes were noticed as well. Below Equinox Logic presents with a figure, for the highest rainfall that occured during the past 100 years. The lowest occurence pattern for the past 100 years was also analyzed.
The inventory data for emissions across India, was also analysed. Based on several components and dimension of data collected and their interactions with the atmosphere, we are close to refining our mathematical model. We do not wish to disclose the methodologies, until the filing of a patent. We are in the process of refining our algorithms  in order to develop a more comprehensive model.

Spatial Analysis- Maximum Temperature Across India

I had been involved in understanding the spatial climatic changes that have occurred over the past century over India. The problem however, is the availability of the data. It is hard to find data in some parts of India. For eg: the data for the maximum temperature changes that have occurred over the past century, helps in understanding the distribution changes with regards to the environmental and the climatic changes from several contributing factors.


While most of the data, helps in modeling studies, I wish to make the model more accurate instead of relying just on the correlation factors. Several dimensions of data has been gathered so far. At present, Equinox Logic has approximately, 4 GB of data analysed across India.
Spatial databases such as Oracle, and PostGIS have helped us tremendously in performing the analysis. Most of the SVG files generated from our analyis have been around 70MB. One can very well understand, how much spatial information, has been accounted in.
Most of the climatic models also rely on the weather patterns. But, with several man-made factors contributing, the number of dimensions keep on increasing. It does not help just collecting the historical data.
The need for a mathematical model is such that, it should very well take these factors into account, but should not rely heavily on the statistical correlation. Associating merely on statistical factors might work but, is certainly not a true representation of the environmental interactions for the study.
Well, we had collected the maximum temperature data from numerous cities across India. A spatial representation of the maximum temperatures across India was prepared. Part of the problem with this was that, the data was in various formats, the structure of the data was not consistent. This meant transforming the data into required formats in order to visualize spatially. The figure is representation for maximum temperature in the past 100 years till 2000 for about 24 cities across India.
