Report on home automation systems (HAS) for Dragon Vale
-------------------------------------------------

-------------------------------------------------
Introduction
-------------------------------------------------
Regarding our new residential property development project, DragonVale. We would like to propose the installation od home automation systems (HAS) to attract more home buyers and a brand will be popular all around Hong Kong. This report aims to discuss the research conducted to identify a suitable the best home automation system, draw conclusions from it and make recommendations on the way forward.
-------------------------------------------------

-------------------------------------------------
Methodology
-------------------------------------------------
Basic functions of home automation systems, namely Wireless Remote Control were extracted from Engineering World Magazine. In order to find out more information regarding the home electronic devices, door access controller and intrusion detector of the system, the Consumer Report 2015 published by Hong Kong Consumers Association was studied and relevant information was analyzed. The official quotations of the systems provided by our designated supplier, were also obtained for comparison.
-------------------------------------------------

-------------------------------------------------
Findings
-------------------------------------------------
In terms of operation of the system, CFL is significantly more economical as it is only $15,000 per system, whereas the LED costs $25,000, which exceeds our budget of $20,000. However, when comparing the lifespans of LED and CFL light bulbs, which are 12 years and 4 years respectively, LED bulbs can last much longer than CFL’s. It is also worth noting that CFL bulbs’ lifespan is one year shorter than our requirement.
-------------------------------------------------

-------------------------------------------------
Regarding power consumption, LED is more energy-efficient than CFL because it consumes fewer watts per unit of light output. As for the installation requirements, CFL can fit easily into many different light fixtures as the light bulbs come in a variety of shapes. However, special fixtures need to be installed for LED as constant voltage has to be maintained to prevent system failure.
-------------------------------------------------

-------------------------------------------------
Conclusion
-------------------------------------------------
After comparing the two lighting systems, the following conclusions can be drawn: * -------------------------------------------------
Neither system corresponds exactly to our requirements. * -------------------------------------------------
If we choose CFL, we can enjoy savings on cost and flexibility in light fixture settings. Yet, expenses on electricity will be higher and the issue of shorter lifespan will need to be addressed. * -------------------------------------------------
If we opt for LED, the initial cost will be much higher and special installation arrangements will be needed. However, this system should be longer-lasting and save more energy.
-------------------------------------------------

-------------------------------------------------
Recommendations
-------------------------------------------------
Two alternative recommendations are given below: 1. -------------------------------------------------
To address the issue of shorter lifespan of CFL, it is suggested that the company purchase extra bulbs in case replacement is needed before the end of the renovation cycle. 2. -------------------------------------------------
If we decide to install LED, it is suggested that savings in electricity bills and a longer renovation cycle of 5 years or more may be used to compensate for the additional installation costs.

...Name: Radhika K Section: i Reg No: 1221055 CONSEQUENCES OF DEMAND AND SUPPLY MISMATCH IN THE ENTERTAINMENT INDUSTRY Introduction: The entertainment industry is in the race to embrace corporates, and the production houses today are vying with each other to reach out to the global markets. With increasing incomes of the common man and broad room for expansion, industry representatives and analysts say that the film and entertainment sector has remarkable potential for growth. Movie production tycoons are aiming to develop content and partnerships to conquer both domestic and international audiences. Demand and Supply The Indian film industry produces roughly twice the number of movies as the American film industry, and sells 2.5 times the number of box office tickets as the U.S market. However, the Indian film industry box office revenues have been under the scanner; in 2008 Indian films earned only USD 1.6 billion compared to Hollywood's USD 9.7 billion, though ticket prices in India are less expensive than those in the U.S. or Europe. Factors affecting the mismatch: This scene is attributed to screen penetration and consumer spending still being considerably less as compared to the global scene. India is still a very price-conscious market. Also, cinema business is a tertiary demand and is the last in the chain of decision-making from a consumer’s perspective. However, demand for luxury goods, cinema tickets are said...
