RECENT PROJECTS

Website Access Log Analysis Module:

Configure cron daemons to run a shell to routinely collect the changes of the access.log via flume and store on the HDFS renamed by the formatted date string. After cleaning it with a formatting MapReduce program, use HIVE to generate the required data (for simplicity, only aggregate rows according IP address instead of session id or specific cookies) and store back to relation db via sqoob for back-end’s further use. Web-based Supply-Chain System:

A web-based struts2+spring+hibernate supply-chain system to manage import, export and exchange goods of a warehouse with respect to roles departments and users. Use jQuery-plugins to encapsulate the front-end interface and codes. Basic DAO CRUD is abstract out of the regular DAO. And the whole project is divided into independent modules according to the service logic.

Web-based Linkedin-Like project built with S2SH frameworks: A web-based struts2+spring+hibernate Linked-in Imitation system, provides user registering with university, skills, companies and languages selection, searching relating users, collecting users’ location(HTML 5 features) data and showing their connections on Google Map.

Several kernel modification tasks for the purposes of understanding the mechanism of Linux kernel: Several kernel modification tasks covering booting, memory addressing & management, exception gates handling and file system management.

Web-based E-store Project of MVC architecture built with PHP: Imitate MVC architecture via PHP and implement all basic features of an on-line store. EDUCATION

Data Analysis using WEKA

Tools: MatlabR2015b, weka3-6-13, Maven

First use Matlab to initial anaylyse the data and have a big picture of the specific pattern needed to mine. Then format and clean the required data, and use apache-commons-csv to output the required csv file. 10-fold the cleaned formatted data.

Then with 9 of the 10-folded data use WEKA to generate the ADTree(Decision tree) and statistic probabilities to support Naive Bayes prediction. And use the rest one of the 10-folded data to test and verify the data. Repeat it for 10 times to verify the modules created reach the requirement, which is cross-validation. https://web.njit.edu/~wl256/download/cs634/li_wentao_finalproj.pdf AprioriAlg Module

Network Analysis via WireShark

Tools: WireShark

This objective of this project is an intensive study of interconnected networks and the corresponding protocols that make interconnected architectures function as a single unified communication system. It covers a wide variety of topics including a brief overview of OSI and TCP/IP architectures, Internet History and Evolution, Underlying Network Technologies (Ethernet, FDDI, Frame Relay, ATM, etc.), IP addresses, Subnetting and Classless Inter-Domain Routing (CIDR), ARP and RARP, IP over ATM and ATMARP, IP protocol, ICMP, Virtual Private Networks (VPNs), IP version 6, Routing, Multicasting, UDP, TCP and TCP Congestion Control, Client Server Model of Interaction, Domain Name System, BOOTP, DHCP, various Application Protocols such as ftp, tftp, telnet, http, smtp, snmp. Upon successful completion of the course, students will have gained a deep understanding of: i) the Internet Architecture, ii) the network and transport protocols that support its operation, iii) the architectural design of the software implementation of some of these protocols, iv) various application protocols that use the Internet infrastructure to provide useful services to end users, v) how to study and analyze the behavior and operation of protocols using a packet analyzer. https://web.njit.edu/~wl256/download/cs656/project.tar.gz PL/SQL Programming tasks

Environment: Oracle 11g, Hadoop-2.0 HBASE0.96.2

Tools: Webstorm11, SqlDeveloper4.1.2, AquaDataStudio-15 Several tasks covering: PL/SQL as "normal" language PL/SQL accessing tables Using AQUA for Oracle programming Object-Oriented Modeling Inserting etc. in PL/SQL Object-Oriented DBs Triggers in PL/SQL Object-Relational DBs Objects in SQL HTML and JavaScript Intro to XML Database Security XML in Oracle SQL Querying XML Distributed Databases PSP Programming Introduction to UNIX/LINUX use (brief) Web databases No-SQL databases Intro to HBase Indexing and Performance Tuning https://web.njit.edu/~wl256/download/cs632/Binder_hws_wl256.pdf Huffman Encoder & Decoder

Environment: Scientific Linux release 6.7 (Carbon) Tools: Eclipse - c/c++

Implement Huffman Coding . The implementation work not only on text files (e.g. .txt, .c, .java etc) but also on binary files (e.g. .pdf, .jpg, mpeg, and other executables). Argument filename in the command-line below is an arbitrary file-name. It can be the name of this PDF file p1610s15.pdf, or its text (LaTeX) source p1610s15.tex or some image file image1.jpg or some movie file such as 01aug25 flare.mpg or something else. The suffix

(sometimes called the extension) of filename is what follows the dot (sometimes we include the dot as part of the suffix). Thus for image1.jpg, the suffix is jpg or .jpg; other suffixes above are pdf, tex, mpg. Thus Huffman coding

(encoding or decoding) of a 2MB file should not take more than 2 minutes in Java, C, or C++ on an AFS machine. The implementation has its own Heap/PriorityQueue. https://web.njit.edu/~wl256/download/cs610/pp_5692_complete.tar.gz C/S online CHATROOM
