Check out some of the things I've worked on.

• Tool for searching the US patent database

  Using d3 I developed an interactive way to explore the US patent database as a demo request for a client on Upwork. The tool allowed users to filter and group by multiple criteria, and follow the bubble chart to find the information they seek.

  

• Managing Java Dependencies for Mendix Modules

  In a blog post on Mendix I write about how to overcome the main issue when developing modules: dependency management. Using Gradle I show how one can deal with transitive dependencies & duplicate jars.

  

• Electric vehicles assisting the power system during transients

  Using the V2G concept which allows plug-in electric vehicles to feed power back to the grid we improve stability when the system is subjected to large disturbances. Verified through simulations using real data.

  

• Sentiment analysis on forum posts in Macedonian

  Classify posts as having a positive, negative or neutral sentiment on a topic. Users maintain a positive attitude when discussing food and shopping, but become grumpy when the focus shifts to the economy and global affairs.

  

• Interactive visualization of child obesity rates in Macedonia

  Obesity rates in different regions are presented using a color-coded interactive map. Percentage of kids who are overweight/obese are also divided by gender, ethnicity and regional development; or year 2010|2013.

  

• Biology inspired cooperation in wireless networks

  Applied biological mechanism such as network reciprocity to encourage cooperative behaviour in wireless networks. The result was reduced energy consumption for the group as a whole but also for individual nodes.

  

• An interactive dashboard with custom sized and placed widgets

  Building on top of a previous dashboard solution I allowed for widgets of different sizes. Users can drag around and reorder their widgets so that their favorite widget are in the spotlight. Preferences are automatically saved.

  

• Decentralized vehicle-to-grid for improved steady-state stability of power grids

  Local frequency measurements are all the information required to control a fleet of plug-in electric vehicles. Using a simple control function we increase system stability and robustness with respect to small disturbances.

  

• Traffic infrastructure: planned underground speedway analysis

  Applied tools from network science to foresee the effects of building a new speedway in Skopje. Average travel times are reduced and some current congestion sites disperse, but new ones are formed.

  

• Bridging Online and Offline Social Networks: Multiplex Analysis

  We study student friendships in real life and on Facebook, which come in two flavours: weak and strong. Based on this different types of network ties we define and analyse a multiplex network with 4 layers.

  

• Just-in time Macedonian thesaurus and dictionary: for Word, Writer and PDF

  A web service that provides definitions and translations for Macedonian words, and integrates information from Wikipedia on important places, people and more. Ready as a plug-in for MS Word, soon for Writer and PDF.

  

• Analysing the temporal aspects of twitter networks

  We looked at how twitter networks evolve over time by monitoring network metrics such as average distance, clustering, degree distr. etc. The network undergoes constant changes to keep in pace with current trends.

  

• County Scholar: Visualizing census data

  As per request from Tim Kubal I developed a soltuions using Highcharts that allows users to explore data from the US census. Users can select from different indicators; use different chart types: bar,line and area, and filter the data by county, state or whole nation.

  

• Building hierarchies from flat tag clouds: important navigation aids

  We examine how agglomerative clustering can help organize information on content-rich websites. Using only tag-cloud data we group related tags and/or tag-clusters, independently of the actual content.

  

• Optimal sensor placement for pollutant detection in water networks

  Showed how algorithms for sensor placement can be sped up by considering only a fraction of pollution scenarios. Demonstrated that network topology and centrality measures greatly influence node observational value.

  

• Collection of digital resources in the Macedonian language

  Developed a web application that allows fast customized searches using wildcards, bigrams or trigrams and lexicological meaning. Search implemented in lucene supported by regex matches for finding example usage.

  

• Control architecture for power systems with plug-in electric vehicles

  Design based on three-tier SoC: core operators, vehicle aggregators, individual car owners. Dedicated ethernet network with MPLS for low lag and reliability (tiers 1-2), supported by wi-fi (tiers 2-3).

  

• Predicting your followers based on your tweets with machine learning

  In order to get the predictions right we integrate both network data (followers) and text data (tweets). Looked at activity patterns, hashtag usage, tweet content, retweet frequency and how they influence befriending.

  

• Promoting cooperation in selfish mobile wireless nodes

  Using simple strategies borrowed from game theory, like tit-for-tat we showed that cooperative behaviour can emerge even from selfish decisions. Cooperation leads to both global and local energy efficiency.

  

• Mood swings in opinions mined from micro-blogs

  Investigate how public opinion about a subject changes with time, based on twitter data analysis. Found strong correlation between national basketball team wins-loses and twitter discussion thread.

  

• Real-time tag recommendation
  Case study: Stack Overflow

  We build a two-level classifier. First level uses PCT (Clus) to choose good tag-clusters. Second level uses binary relevance (MULAN) with SVMs to give actual tag predictions within the clusters. Run-time < 100ms.
