I. Introduction
Here is a project using the printer port of a PC, for control application using software and some interface hardware. The interface circuit along with the given software can be used with the printer port of any PC for controlling up to eight equipments. The interface circuit is drawn for only two device, being controlled by D0 and D1 bit at pin 2 and pin 3 of the 25-pin parallel port. Identical circuits for the remaining data bits D2 through D7 (available at pins 4 through 9) have to be similarly wired. The use of opto-coupler ensures complete isolation of the PC from the relay driver circuitry. Lots of ways to control the hardware can be implemented using software. In C/C++ one can use the out port b (portno, value) function where portno is the parallel port address (usually 378hexfor LPT1) and 'value' is the data that is to be sent to the port. For a value=0 all the outputs (D0-D7) are off. For value=1 D0 is ON, value=2 D1 is ON, value=4, D2 is ON and so on. e.g. If value=29(decimal) = 00011101(binary) ->D0, D2, D3, D4 are ON and the rest are OFF.

II. Background of the Study
In the fast growing world today, it is necessary to control the home from remote locations. Every home is different, and just like you have to instruct your maid in the operation of your home, you have to instruct your PC in your personal preferences. A home automation system is a means that allow users to control electric appliances of varying kind. Home automation is also known as domotics, a contraction of the words “domestic robotics”. When home automation principles are applied to buildings not falling in the “home” category, building automation system is a commonly used term.
Parallel port is a simple and inexpensive tool for building computer controlled devices and projects. The simplicity and ease of programming makes parallel port popular in electronics

...The Research Process Writers usually treat the research task as a sequential process involving several clearly defined steps. No one claims that research requires completion of each step before going to the next. Recycling, circumventing, and skipping occur. Some steps are begun out of sequence, some are carried out simultaneously, and some may be omitted. Despite these variations, the idea of a sequence is useful for developing a project and for keeping the project orderly as it unfolds. Exhibit 3–1 models the sequence of the research process. We refer to it often as we discuss each step in subsequent chapters. Our discussion of the questions that guide project planning and data gathering is incorporated into the model (see the elements within the pyramid in Exhibit 3–1 and compare them with Exhibit 3–2). Exhibit 3–1 also organizes this chapter and introduces the remainder of the book. The research process begins much as the vignette suggests. A management dilemma triggers the need for a decision. For MindWriter, a growing number of complaints about postpurchase service started the process. In other situations, a controversy arises, a major commitment of resources is called for, or conditions in the environment signal the need for a decision. For MindWriter, the critical event could have been the introduction by a competitor of new technology that would revolutionize the processing speed of laptops. Such events cause managers to reconsider their purposes or...

Microsoft Company has basic research sites in Redmond, Washington, Tokoyo, Japan etc.at these research sites work on fundamental problems that underlie the design of future products. For example a group at Redmond is working natural language recognition soft wares, while another works on artificial intelligence. These research centres don’t produce new products rather they produce the technology that is used to enhance existing products or help new products. The product are produced by dedicates product groups. Customization of the products to match the needs of local markets is sometimes carried out at local subsidiaries.

...Myresearch About 30 million other animals. Animal experimentation by scientists can be cruel and unjust, but at the same time it can provide long term benefits for humanity. Animals used in research and experiments have been going on for 2,000 years and keep is going strong. It is a widely debated about topic all over the world. Some say it is inhuman while others say it's for the good of human kind. There are many different reasons why people perform experiments and why others total disagree with it. Each year 20 million animals are produce and breed for the only purpose but to be tested on. Fifty-three thousands of animals are used each year in medical and veterinary schools. The rest is used in basic research. The demand for animals in the United States is 50 million mice, 20 million rats, and aThis includes 200,000 cats and 450,000 dogs. The world uses about 200-250 million animals per year. The problem with working with animals is that they cannot communicate their feelings and reactions. Other people say that they can communicate and react to humans just a well as one person to another. Some of the animals the research's use are not domesticated which makes them extremely hard to control and handle. The experiments that go on behind closed doors are some of the most horrific things a human could think of too torture somebody or something. Animals in labs are literally used as models and are poked at and cut open like nothing is happening. When drug are tested on animals...

...Research Research is a systematic inquiry to describe, explain, predict and control the observed phenomenon. Research involves inductive and deductive methods (Babbie, 1998). Inductive methods analyze the observed phenomenon and identify the general principles, structures, or processes underlying the phenomenon observed; deductive methods verify the hypothesized principles through observations. The purposes are different: one is to develop explanations, and the other is to test the validity of the explanations. One thing that we have to pay attention to research is that the heart of the research is not on statistics, but the thinking behind the research. How we really want to find out, how we build arguments about ideas and concepts, and what evidence that we can support to persuade people to accept our arguments. Gall, Borg and Gall (1996) proposed four types of knowledge that research contributed to education as follows: 1. Description: Results of research can describe natural or social phenomenon, such as its form, structure, activity, change over time, relationship to other phenomena. The descriptive function of research relies on instrumentation for measurement and observations. The descriptive research results in our understanding of what happened. It sometimes produces statistical information about aspects of education. 2. Prediction: Prediction research is intended to predict a phenomenon that will occur at time Y from information at an earlier time X. In educational...

...STEP 1etasblish the need for research We have to consider if it is a real need for doing a research? Research takes time and costs money. If the information is already available, decisions must be made now, we cant afford research and costs outweigh the value of the research, then the research is not needed. Step 2 define the problem or topic State your topic as a question. This is the most important step. Identify the main concepts or keywords in your question. Problem maybe either specific or general. Step 3 establish research objective Research objectives, when achieved, provide the Information necessary to solve the problem identified in Step 2. Research objectives state what the researchers must do. Crystallize the research problems and translate them into research objective. At this point, we will pin down the research question. Step 4 determine research design The research design is a plan or framework for conducting the study and collecting data. It is defined as the specific methods and procedures you use to acquire the information you need. based on the research objectives, we will determine the most appropriate research design: qualitative and/ or quantitative. • Exploratory Research: collecting information in an unstructured and informal manner. • Descriptive Research refers to a set of methods and procedures describing marketing variables. • Causal Research (experiments): allows isolation of causes and...

...Research Article Research is important to every business because of the information it provides. There is a basic process to researching information and that process begins by deciding what information needs to be researched. The next step is to develop a hypothesis, which describes what the research paper is about and what the researcher’s opinion is regarding the topic. The research article chosen for this paper is titled, “The Anchor Contraction Effect in International Marketing Research.” The hypothesis for this paper is, “This raises the issue of whether providing responses on rating scales in a person’s native versus second language exerts a systematic influence on the responses obtained.” Simply explained, the hypothesis of this paper is to determine whether research questions should be in a person’s native language rather than expecting them to respond to questions in a language in which they might not be fluent. The hypothesis of this paper was accepted based on the research data gathered by the research team. This hypothesis was supported by nine studies using a variety of research methods. The research methods provided data that demonstrated the level of inaccuracy based on questions being asked in a language that was not the respondent’s native language. The research data provided insight into the probability of more accurate results when the respondent was asked questions in a manner that related well with their culture. There are several implications...

...ACE8001: What do we mean by Research? & Can we hope to do genuine Social Science Research (David Harvey)  What do we mean by research? What might characterise good research practice? There is no point in us trying to re-invent the wheel - other and probably more capable people than us have wrestled with this problem before us, and it makes good sense and is good practice to learn what they have discovered.  In other words - we need to explore more reliable and effective methods and systems for the pursuit of research than we have been doing so far. What is research? Dictionary Definitions of Research: * "The act of searching closely or carefully for or after a specified thing or person" * "An investigation directed to discovery of some fact by careful study of a subject" * "A course of scientific enquiry" (where scientific = "producing demonstrative knowledge") Howard and Sharp (HS) define research as:  "seeking through methodical processes to add to bodies of knowledge by the discovery or elucidation of non-trivial facts, insights and improved understanding of situations, processes and mechanisms".  [Howard, K. and Sharp, J.A. The Management of a student research project, Gower, 1983 - a useful and practical “how to do it” guide] Two other, more recent guides are: Denscombe, Martyn, 2002, Ground rules for good research: a 10 point guide for social research,  Open University Press.

...solve analytic models or whatever, but they often fail to demonstrate that they have thoroughly thought about their papers—in other words, when you push them about the implicit and explicit assumptions and implications of their research models, it appears that they haven’t really given these matters much thought at all.[1] Too often they fall back on saying that they are doing what they are doing because that is the way it is done in the prior literature, which is more of an excuse than a answer. (Of course, once a researcher reaches a certain age, they all feel that youngsters aren’t as good as they were in the good old days!) Therefore, in this class we shall go beyond simply studying research in managerial accounting. For many of you, this is your first introduction to accounting research and to PhD level class. Hence, in these classes we shall also learn how to solve business problems systematically and to understand what it means to have thoroughly “thought through” a paper. We begin not with academic research, but with some real world cases, because we should never forget that ours is an applied research field: accounting research is a means towards the end of understanding business and is not an end in itself, in the way pure science research is. Developing a systematic procedure for solving a real world business problem is the starting point for developing a...

...manger know about research when the job entails managing people, products, events, environments, and the like? Answer: Research simply means a search for facts – answers to questions and solutions to problems. It is a purposive investigation. It is an organized inquiry. It seeks to find explanations to unexplained phenomenon to clarify the doubtful facts and to correct the misconceived facts. Research is the organized and systematic inquiry or investigation which provides information for solving a problem or finding answers to a complex issue. Research in business: Often, organization members want to know everything about their products, services, programs, etc. Your research plans depend on what information you need to collect in order to make major decisions about a product, service, program, etc. Research provides the needed information that guides managers to make informed decisions to successfully deal with problems. The more focused you are about your resources, products, events and environments what you want to gain by your research, the more effective and efficient you can be in your research, the shorter the time it will take you and ultimately the less it will cost you. Manager’s role in research programs of a company: Managing people is only a fraction of a manager's responsibility - they have to manage the operations of the department, and often have responsibilities towards the profitability of the organization. Knowledge of research can be very helpful...

...goal of the research process is to produce new knowledge or deepen understanding of a topic or issue. This process takes three main forms (although, as previously discussed, the boundaries between them may be obscure): * Exploratory research, which helps identify and define a problem or question. * Constructive research, which tests theories and proposes solutions to a problem or question. * Empirical research, which tests the feasibility of a solution using empirical evidence. There are two ways to conduct research: Primary research Using primary sources, i.e., original documents and data. Secondary research Using secondary sources, i.e., a synthesis of, interpretation of, or discussions about primary sources. There are two major research designs: qualitative research and quantitative research. Researchers choose one of these two tracks according to the nature of the research problem they want to observe and the research questions they aim to answer: Qualitative research Understanding of human behavior and the reasons that govern such behavior. Asking a broad question and collecting word-type data that is analyzed searching for themes. This type of research looks to describe a population without attempting to quantifiably measure variables or look to potential relationships between variables. It is viewed as more restrictive in testing hypotheses because it can be expensive and time consuming, and typically limited to a single set of research subjects. Qualitative...

...Volume 3, number 2 What is critical appraisal? Sponsored by an educational grant from AVENTIS Pharma Alison Hill BSC FFPHM FRCP Director, and Claire Spittlehouse BSc Business Manager, Critical Appraisal Skills Programme, Institute of Health Sciences, Oxford q Critical appraisal is the process of systematically examining research evidence to assess its validity, results and relevance before using it to inform a decision. q Critical appraisal is an essential part of evidence-based clinical practice that includes the process of systematically finding, appraising and acting on evidence of effectiveness. q Critical appraisal allows us to make sense of research evidence and thus begins to close the gap between research and practice. q Randomised controlled trials can minimise bias and use the most appropriate design for studying the effectiveness of a specific intervention or treatment. q Systematic reviews are particularly useful because they usually contain an explicit statement of the objectives, materials and methods, and should be conducted according to explicit and reproducible methodology. q Randomised controlled trials and systematic reviews are not automatically of good quality and should be appraised critically. www.evidence-based-medicine.co.uk Prescribing information is on page 8 1 What is critical appraisal What is critical appraisal?

...How To Formulate Research Problem? Posted in Research Methodology | Email This Post Email This Post Formulating the research problem and hypothesis acts as a major step or phase in the research methodology. In research, the foremost step that comes into play is that of defining the research problem and it becomes almost a necessity to have the basic knowledge and understanding of most of its elements as this would help a lot in making a correct decision. The research problem can be said to be complete only if it is able to specify about the unit of analysis, time and space boundaries, features that are under study, specific environmental conditions that are present in addition to prerequisite of the research process. Research Process Research process is very commonly referred to as the planning process. One important point to be kept in mind here is to understand that the main aim of the research process is that of improving the knowledge of the human beings. The research process consists of the following stages – 1. The Primary stage :– This stage includes – a. Observation – The first step in the research process is that of the observation, research work starts with the observation which can be either unaided visual observation or guided and controlled observation.It can be said that an observation leads to research, the results obtained from research result in final observations which can play a crucial part in carrying out further research.
