• Designed a user friendly and robust website for a fish farm in Rwanda according to their need through communications with them.
• Customer question posting board, Google map and a contact form were implemented to improve the communication
between customers and the farm. Multiple user flows were applied: visitors and administrators.
• A search engine using MySQL, responsive navigation bars, photo sliders were used to provide a responsive website.

• Developed a personal online image album using PHP, HTML, CSS, JavaScript and JQuery.
• Supported features: search forms, image details lookup, login functionality(Add a login form (username and password) to allow users to use the site as an admin. A user must be logged in as an admin in order to add a new photo or album), edit an existing photo or album, and delete an existing form or album.edit and delete albums, edit and delete images.
• Contains: a photo slider, a back-to-top buttom.

• Supported Features: new account creation, user authentication, online player invitation, colored discs dropping, player moves validation by server, AJAX, JSON and database concurrency control technologies.
• Implemented by PHP, CodeIgniter, HTML, CSS, JavaScript and JQuery.

• Developed StockAccount and BankAccount to manage the customer account information
• In Stock Account, implemented functions: checking the stock price from a random file and the current portfolio, buying and selling shares and viewing transaction history
• In Bank Account, implemented functions: viewing account balance and history, depositing and withdrawing money

• Performed PageRank computation on a web graph (685230 nodes and 7600595 edges) on AWS Elastic MapReduce.
• Optimized by using blocked matrix multiplication which reduced passes needed from more than 20 to 6.
• Conducted comparison between METIS partitioned graph (nicely partitioned) and random partitioned graph for cross-block PageRank update. Achieved a relative residual error below 0.1%.

• Performed k-means clustering algorithm in Ubuntu involving 186,000 points.
• Implemented by creating initial centroids either randomly or by loading them from a file.

• Maintained scalable B+ tree index for efficient data processing with functions search, insertion and deletion.
• Implemented index/leaf node overflow with node splitting and underflow with node merging and redistribution.
• Evaluated searching performance between B+ tree and array among 10,000 (key, value) pairs.

• Implemented Logistic Regression and Naive Bayes algorithms for spam classification with accuracy 99%
• Applied gradient descent algorithm for optimization

Aerobic granules were considered to be a special case of biofilm composing of self-immobilized cells. During the last 20 years, intensive research in the field of biological wastewater treatment and other applications demonstrated that biofilms were often more efficient for water purification than suspended activated sludge.

Aerobic granules were considered to be a special case of biofilm composing of self-immobilized cells. During the last 20 years, intensive research in the field of biological wastewater treatment and other applications demonstrated that biofilms were often more efficient for water purification than suspended activated sludge. To date, the application of aerobic granular sludge was regarded as one of the promising biotechnologies in wastewater treatment. Because of the unique granule attributes, the aerobic granulation technology was recently developed for treating high strength wastewater containing organics, nitrogen, phosphorus, toxic substances and xenobiotics. However, there is little research did on how cultivation with one aromatic compound influences the biodegradation of compounds similar to that. Since our four compounds’ (phenol, hydroquinone, catechol and resorcinol) degradation path ways share some common elements, this project aimed to verify that cultivating acetate-fed granules with phenol can improve the removal of three dihydroxybenzenes. In this research, acetate-fed granules were cultivated with phenol. Samples from degradation experiments with dihydroxylbenzenes were analyzed and quantified with high-performance liquid chromatography coupled to a UV detector (HPLC-UV). Current result shows the degradation of catechol and resorcinol obviously improved by phenol-cultivation. Show less

• Delivered multiple parcels with their own destinations using multiple trucks simultaneously on random maps.
• Developed efficient package delivery system by implementing graph searching using Dijkstra’s algorithm.
• Optimized delivery cost by taking shortest distance, parcel’s colors, truck’s colors into account and through secured competition with synchronization.

Investigating and analysis of the viability to replace existing cloud cover sensors from expensive TEPT4400 phototransistors to the comparable/cheaper alternative LI-COR200 pyranometer. Data collection performed with Cambellsci Datalogger and analyzed using Matlab calibration.
