4-(4-Chlorophenyl)-7,7-dimethyl-7,8-dihydro-4H-1-benzopyran-2,5(3H,6H)-dione
Hao Shi
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536809051320
Abstract: The title compound, C17H17ClO3, has been synthesized by the reaction of p-chlorobenzaldehyde, isopropylidene malonate and 5,5-dimethylcyclohexane-1,3-dione with triethylbenzylammonium chloride in water as a green solvent. The six membered pyranone ring of the hexahydrocoumarin system has a screw-boat conformation while the dimethylcyclohexenone system has a distorted envelope conformation. The dihedral angle between the least-squares planes of the coumarin ring system and the benzene ring is 85.64 (9)°.
Ethyl (1R,4S,5R,9S,10R,13S)-5,9,13-trimethyl-14-methylene-14-oxotetracyclo[11.2.1.01,10.04,9]hexadecane-5-carboxylate

Abstract: The title compound, C22H34O3, was synthesized from isosteviol. The asymmetric unit contains of two independent molecules with the same absolute configurations. In both the molecules, the three six-membered rings adopt chair conformations, the stereochemistry of the A/B and B/C ring junctions are trans, and the five-membered ring D adopts an envelope conformation.
9-(2,4-Dichlorophenyl)-3,3,6,6-tetramethyl-3,4,5,6-tetrahydro-9H-xanthene-1,8(2H,7H)-dione
Hao Shi
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810046702
Abstract: The title compound, C23H24Cl2O3, was synthesized by reaction of 2,4-dichlorobenzaldehyde and 5,5-dimethylcyclohexane-1,3-dione in ethylene glycol. The central ring of the xanthene moiety is almost planar (with an r.m.s. deviation of 0.0268 from the least-squares plane) while the two outer rings, in a cis arrangement, display envelope conformations. The ring of the 2,4-dichlorophenyl substituent is nearly perpendicular [85.89 (4)°] to the xanthene ring system.
4-(4-Methoxyphenyl)-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydrochromene-2,5-dione

Acta Crystallographica Section E , 2009, DOI: 10.1107/s160053680904971x
Abstract: The title compound, C18H20O4, was synthesized by the reaction of 4-methoxybenzaldehyde, 2,2-dimethyl-1,3-dioxane-4,6-dione and 5,5-dimethylcyclohexane-1,3-dione with triethylbenzylammonium chloride in water as a green solvent. In the molecule of the title compound, the six-membered pyranone ring of the hexahydrocoumarin system has a screw-boat conformation while that of the dimethylcyclohexenone system has a distorted envelope conformation. The CMe2 portion of this ring is disordered over two positions with refined occupancies of 0.721 (7) and 0.279 (7).
Developing E-Learning Materials for Software Development Course
Hao Shi
International Journal of Managing Information Technology (IJMIT) , 2010,
Abstract: Software Development is a core second-year course currently offered to undergraduate students atVictoria University at its five local and international campuses. The project aims to redesign the existingcourse curriculum to support student-centred teaching and learning. It is intended to provide a learningcontext in which learners can reflect on new material, discuss their tentative understandings with others,actively search for new information, develop skills in communication and collaboration, and buildconceptual connections to their existing knowledge base. The key feature of the cross-campus curriculuminnovation is the use of Blackboard, short for Blackboard Learning System, to assist in course contentorganization and online delivery. A well-defined and integrated case study is used throughout the courseto provide realistic practical experience of software development. It allows students to take control oftheir own learning while at the same time providing support to those students who have particularlearning difficulties. In this paper, the developed curriculum and the learning outcome are described. Thee-Learning material and various Blackboard tools used for teaching and learning activities arepresented. Finally, conclusion is drawn from classroom experience.
An Interactive Zoo Guide: A Case Study of Collaborative Learning
Hao Shi
International Journal of Multimedia & Its Applications , 2010,
Abstract: Real Industry Projects and team work can have a great impact on student learning but providing theseactivities requires significant commitment from academics. It requires several years planningimplementing to create a collaborative learning environment that mimics the real world ICT (Informationand Communication Technology) industry workplace. In this project, staff from all the three faculties,namely the Faculty of Health, Engineering and Science, Faculty of Arts, Education and HumanDevelopment, and Faculty of Business and Law in higher education work together to establish a detailedproject management plan and to develop the unit guidelines for participating students. The proposedproject brings together students from business, multimedia and computer science degrees studying theirthree project-based units within each faculty to work on a relatively large IT project with our industrypartner, Melbourne Zoo. This paper presents one multimedia software project accomplished by one of themulti-discipline student project teams. The project was called ‘Interactive ZooOz Guide’ and developedon a GPS-enabled PDA device in 2007. The developed program allows its users to navigate through theZoo via an interactive map and provides multimedia information of animals on hotspots at the ‘Big Cats’section of the Zoo so that it enriches user experience at the Zoo. A recent development in zoo applicationsis also reviewed. This paper is also intended to encourage academia to break boundaries to enhancestudents’ learning beyond classroom.

Abstract: The title compound, C20H24O5, isolated from Rabdosia var. lophanthoides Hara, is built up from six fused rings. Cyclohexane ring A adopts a chair conformation, ring B exists in a screw-boat conformation and ring C adopts a boat conformation; the three five-membered rings D, E and F adopt envelope conformations.
Building a Portable Computer Lab with Bootable USB Hard Drives Using Virtualisation
Hao Shi
International Journal of Computer Science & Information Technology , 2012,
Abstract: Centralization of services is a global trend in universities worldwide. IT services in a university become asolo department to provide common IT support for the entire university community such as staff, studentsand visitors. Special services required for Computer Science and Information Technology courses are quiteoften not part of IT service agreements. The shared common computer labs are tightly controlled by ITservices and could not be used to deliver some specialised course such as Microsoft Active DirectoryConfiguration and Management. A dedicated computer lab is no longer a viable option to provide apractical solution with three-year University leased computers. The challenge in providing a long-termsolution heavily relies on the individual academic staffs who deliver such courses. There is an urgent needto find a new long-term working solution for this problem. After numerous search and research in findingan optimal solution, a portable computer lab using virtualisation is proposed. Instead of using a desktopcomputer in a common lab, each student enrolled in the course such as Microsoft Active Directory isallocated a customised USB hard dive. The USB drive contains a bootable Windows 7 Operating System aswell as six Windows Servers operated under Microsoft Windows Virtual PC. This not only allows thestudents to use a common computer lab but also enable them to totally control their learning with flexibilitywhich was not achievable in the past. This paper aims to share the knowledge as well as tricks and tipsgained through the process and to provide step by step instructions for building the customised USB harddive. It is expected that the concept of a ‘portable’ computer lab using virtualisation will provide insightinto delivery of IT courses in the future.
