Design requirements of an efficient solar thermal collector Incorporated Into excellent hot water systems: Detailed analysis of the irradiative and convective heat transfers Introduction: With the increasing problems associated with the fossil fuel related energy production, exploration and efficient utilization of renewable energy Is the key to have a sustainable energy future.Solar energy Is the main source of a clean and renewable energy, and collecting solar power as thermal energy Is becoming increasingly important especially at this time when there is increasing emphasis on enable energy and the cost of conventional power generation is increasing. Currently, solar thermal panels are becoming more and more popular because they can be placed on many buildings and common places, collecting and converting solar energy Into thermal energy, and supplying thermal energy through hot water systems.However, how to make solar energy collection and utilization more efficient is still a maj or problem. Literature Review: The solar thermal collector is the device that absorbs the incoming solar radiation, inverts it Into heat, and transfers this heat into fluid flowing through the collector. Thus, solar thermal collectors are special kind of heat exchangers that transform solar radiation energy to Internal energy of the transport medium. In recent years, many researches have been aimed to investigate and enhance the thermal efficiency of different kind of solar thermal collectors.Fernando-Garcia et al. Reviewed the parabolic-trough collectors and their Incorporation Into practical applications such as electricity generation and domestic hot water and space heating. Doughier et al. [2] researched the performance optimization of a solar water heater flat plate collector. Giuliani et al. Optimized solar water heating system through water replenishment. In addition, Caner et al. [4] used artificial neural network as a new method to conduct the thermal performance analysis s o as to obtain a more accurate result.Nonetheless, many questions remain unanswered. For example, incorporate an efficient solar thermal collector into existing hot water systems? What analyses should we do in order to design an efficient solar thermal collector? What approaches may we use for such analyses? Proposed Research: The Computational Fluid Dynamics (CUFF) has been applied to many practical engineering problems including CUFF modeling to analyses energy efficiency involving heat transfer, convection, thermal radiation and energy storage.CUFF related research projects being conducted by He's group across a broad selection of topics. For example, they reported that in the air conditioning industry chilled water storage systems are one form of cool thermal storage technology that can be used to time haft the electrical load of the system from the peak day periods to off peak night time periods[5]. Therefore, CUFF simulation and modeling should significantly help us finding an swers to the above questions and contributing to the improvement of the efficiency of solar energy collection, storage and utilization.As a senior student majoring in Thermal Energy and Power Engineering, I have a solid knowledge background on Heat Transfer, Thermodynamics, Fluid Mechanics, and CUFF. I have also had real world internships such that during my internship at XX, I acquired an amount of knowledge on the research of the solar water heater in buildings. In addition, the project XX that I am currently doing enables me to use CUFF well, and helps me understand the overall concept and process of how to conduct a research. Furthermore, I have communicated with XX, and has agreed to help me and guide me in my research project.The main objective of this proposed research is to evaluate the design requirements of an efficient solar thermal collector supported by detailed analysis of the irradiative and convective heat transfers. Detailed analyses of the irradiative and convectiv e heat transfers will be conducted, and the design requirements of an efficient solar thermal collector will be evaluated. With the results obtained through detailed analyses and evaluations, the research will aim to design, construct and test the requirements of efficient solar thermal collectors that are incorporated into existing hot water systems. Proposal Hotel International and the Roaring Dragon Hotel alma Student Sullivan university MGM 510 Executive Summary This proposal provides a roadman toward Improving communications between the Hotel International (HI), a global hotelier, and the management control of the Roaring Dragon Hotel (3RD), one of the original three-star hotels in southwest China and a state owned enterprise (Grainier, 2008).Failure to recognize cultural norms and the relationship between employees, customers, and contractors will result in dramatic failure of modernization and an effective business plan (Grainier, 2008). Introduction: Management Control Takeover The management control takeover of the Roaring Dragon Hotel (3RD). One of the original three-star hotels in southwest China had a direct impact on the hotel's employees, its popularity among current customers, and generating profit. 3RD is a state owned enterprise located in southwest China by Hotel International (HI), a global hotelier (Grainier, 2008).McNa lly (2011) observed, â€Å"Over the past thirty years China has witnessed a gradual transition towards a capitalist political economy with an emphasis on capital accumulation, market competition, and International economic Integration† (p. 1). Background: Deployment of corporate Governance and Global Marketing The provincial government was concerned that the hotel would not meet their potential and needed modernization. The current general manager, Titan Went, focused more on the security of its employees and not the hotel's profit margin.The state negotiated new management hoping to drive increased revenue (Grainier, 2008). Currently, the 3RD had a great reputation. â€Å"Since the early sass it had enjoyed a long, colorful history and reputation as the region's premium guesthouse† (Grainier, p. 1). Problem: Organizational culture There was a deep division separating the organization cultures of RED and HI. The HI business strategy and environment went against the cur rent guan-based or Influence-based organizational culture. Guan Is the Chinese word describing Chinese business.The culture at 3RD promoted social business relations, drinking and eating etiquette, exchanging gifts and donations for favors. RED employees have a strong psychological need associated with receiving and giving â€Å"perks† that is tied their self-identification. These interpersonal relationships with each other and customers are relatable to both partnerships and friendships (Yuan & Allele, 2007). In addition, 3RD employees were excited to work for the hotel because it showed they had achieved status based on the strength of their social connections.3RD was not as worried about the hotel's decline in popularity, revenue, or in delivering quality service standards. 3RD also had a long nepotistic history tied to the Guiana culture (Grainier, 2008). HI considered the networks of influence irrelevant and changed non-productive behaviors. New performance standards wer e enacted and employees unwilling to meet these new standards were fired. HI also began processing scheduled redundancy program. Once a place considered as secure employment, became uncertain and untrustworthy.This caused a deep division separating organizational cultures between RED and HI (Grainier, 2008). Another concern was the lose of important contracts. Nu If Travel was unsatisfied with the new pricing structures and canceled all future tours. This caused a reduction in revenue and also made competition look more favorable for unhappy employees. The conditions at 3RD continued to deteriorated with the loss of industry contacts and Guiana connections (Grainier, 2008).Opportunities: Satisfied Employees & Success HI has the business strategy to promote efficiency in the hotel's domestic management style and processes, thereby increasing income and popularity if they recognize the risk of alienating the current organizational culture. A healthy balance should be addressing all th e concerns from both parties (Grainier, 2008). Robertson wrote, â€Å"people form personal intentions to achieve a variety of desired outcomes, and are satisfied with their Job to the extent that they perceive these goals will be successfully attained† (2009).By improving communications, HI has the opportunity to promote efficiency and improve processes at 3RD with the help of the employees. Recommendation: Open Communications HI should give special consideration to address changes in culture and conditions within 3RD with open communications between HI management, 3RD employees, contractors, and the public (Grainier, 2008). Addressing concerns and anticipating current customers' needs and expectations will help the â€Å"gradual transition towards a capitalist political economy with an emphasis on capital accumulation, market competition, and international economic integration† (McNally, p. ). Communicate hanged, train new employees, inform contractors, and especially listen to your customers and the public (Grainier, 2008). Want, D (1999) asserted, â€Å"Guiana practices have played an important role in China's capitalist transition, making them an indispensable element of any conceptualization of Chinese capitalism† (as cited in McNally, p. 7). Friendship, trust, honesty, influences offer a more direct and open communication style. By nurturing relationships already established and identifying critical industry contacts, HI can positively establish themselves in the China market (McNally, 2011) (Grainier, 2008). Proposal They published their products in faceable and customer can order through sending message or phonically or else vaults the store. Is hassle for the customer to go their store especially if their house Is far from the store. It is not convenient to the customer to talk in phone to ask about the products and also it makes hassle to the owner to explain the product one by one. Imagine how many customer will call in one day to ask about the product so it's really makes hassle. The company need computerizing system in order to manage their time and also customer can read/view the product so they don't need to make a call to ask the owner to explain the product one by one.It also a big benefits to the store to Increase he sales. Through Online Ordering System it can minimize the time for the customer and the owner. Let organized and meet the needs of customers more efficiency and reliable. Customer can order anytime they want. Statement of the Problem The problem was lacking of online websi te system. The Barbara Pearl has no specific software that help customer In ordering through online _ The Barbara Pearl manage their business manually especially in taking customers order. More hassle to the customer to order especially if they are far from the store.Objectives of the Study To Increase speed of service, sales volume and customers satisfaction To enable customers to know the all beauty products of Barbara Pearl before ordering To increase level of accuracy To be able to stand out from competitors by automating daily operations which will give the beauty product providers the opportunity to increase sales To reduce time wasting by eliminating long queues To develop orders for faster and reliable transaction and process Significance of the Study This project is designed to provide an easy access of customers in getting their orders.The researchers will create an online Ordering system for Barbara Pearl Cosmetics that will help the company to increase more customers and make the procedure of ordering much easier. Scope and limitation of the Study Cosmetics since they are still using a manual system in their transactions, payments and even in generating reports. As for the Members, the system will provide an area wherein they can view and manage their orders. They can also request for tracking status provided that they purchased an item. Unlike the members, the guest can only browse the website but no transactions can be held unless they would register. Proposal This document is a proposal for the â€Å"Online Notice Board System† as a major project for my partial fulfillment of the course of Bachelors in Information Technology. The system will be a client-server model and also web-based to facilitate easy access to all clients regard less of where they are and also of the machines they are using. I will also try to integrate the system from the computer desktop program into a mobile application app such as Android and Windows mobile.A motherboard is a wooden or even metal boards where people can leave public assuages, e. G advertise things to buy or sell, events or even memos. My aim in this project is to ease and make information dissemination much easier in a paperless institution such as Await Tablet University College. I intend to focus on Await Tablet University College whereby the software will major be used for Administration purposes. It is intended to support the existing method by which notices and memos are posted in the U niversity environment. Many University and institutions, particularly UTC rely on the wooden motherboard hanging on a wall to display announcement, I. At the library, outside each hostel, at the department offices and also at the administration offices. Many students and staffs face the following problems: 1 . Struggle to check a sing notice board e. G Exam results 2. Destroyed memos and lot of information lost leaving many students uninformed 3. Unregulated display of information (any person can develop a memo and display on the notice board) This project looks at the above problems and try to come up with a solution.Develop a software with a client and server side so as to develop the digital notice board DON) program that will be installed in various computers that a re connected within the Local Area Network of the university compound so as to help spread the information displayed in the notice board faster. 1 . Check the current form of displaying information 2. Develop the Onl ine Notice Board for UTC 3. Test the program with real data. Has UTC implemented the system in its environment? Will UTC adopt the system being developed? How the system will be implemented. Feedback from students and staffs of UTC
