Passive components are components with the inability to amplify or increase voltages, signals or currents but with the potential to reduce the voltage, currents and wave. Although a passive component, resistors are essential in any electric circuit.
Resistors are the readily used electric components present in the market. Though common, their role vary depending on the circuitry with the main reason for use is to provide resistance to current, at times used to regulate resistance such as the use of variable resistance. They are necessary for the creation of several appliances. The oldest types of resistor are the carbon resistor.
Carbon resistors are the common, and the oldest type of resistors by composition type resistor. They are readily available, cheap and used in general purpose circuits. The resistor is composed of a mixture of finely ground carbon dust or graphite and a non conducting ceramic powder to bind it together. It is the oldest design. The resistance value is determined by the amount of carbon inserted in the filler. The resistors in this order do not have close tolerance compared to carbon or metal film types. Typical tolerances of the resistors are +/- 10% or20%. The advantage of the resistor type is the ability to work in high voltage pulses compared to all the other types of resistors (Wilson and Williams, 2011).
The manufacturing procedure of the resistor is similar to metal film resistor. The change being, the tolerance of carbon film resistor is higher at +/-5%. Small resistors from this category are reasonable and often sold in batches.
The resistor in this category is a combination of small rods of ceramics coated with metal or metal oxides such as nickel alloy or Tin oxide. The resistance value is obtained from the thickness of the coating layer. The greater the coating covering the lower the resistance value and vice versa. The metal film resistors come in a variety and with a wide range of

The textile and clothing (T & C) industry in the face of tremendous challenges faces an uncertain future due to the changes in the import policy in the United States. In the past, developing countries had to restrict their exports due to quantitative restrictions forced by stringent bilaterally negotiated quotas. This is now being waived. From 2005 onwards imports from World Trade Organisation (WTO) member countries will no longer be restricted by quotas...
... Sweatshop”and others who favor sweatshop labor argue that it provides a means of employment for the weaker section of the population which helps the lower income population to lead a better livelihood. In addition, such companies provide employment for women, and that would in turn help them to become more independent and self-supportive. While sweatshop labor does provide a means of employment for the people, the mental and physical turmoil endured by the employees is much more than the benefits gained. In addition, the manufacturing of fake goods by itself is illegal as it is a deliberate infringement of the intellectual property rights of companies that produce the original goods. Hence, stricter policies and judicial changes should...

There are four tips for optimizing distribution channels; involvement of high level management, asking the right questions, performing an inventory optimization study and making sure there is adequate labor (Kotler & Lee, 2007).
Involvement of high level management Most organizations, do not involve the shareholders and other directors in the policy making process. They are only involvement in the final output. For effective optimization of distribution channels, all the key stake holders should be involved from the time the company is drafting its distribution strategy (Kotler & Lee, 2007).
Asking the right questions A good distribution channel, should look at all the key sections of an o...

The experiment was set up so as to determine whether and how different is the voltage and current in a parallel and a series circuit. The aim was achieved by setting up a parallel circuit and a series circuit using the same voltage sources, then taking measurements of the current and voltage in the two circuits. It was established that indeed there is a difference in the characteristics of a voltage and series circuit in regard to current and voltage of the circuits. Current is constant in a series circuit while voltage is constant in a parallel circuit (ANWAR, HALL... Report The...
...BUSINESS OPTIMIZATION VIA IOT + Submitted The Internet of Things is a where animals, people or objects are presented with distinctive identifiers as well as the aptitude to transmit information automatically over a system without necessitating human to computer or human-to-human contact (BESSIS 2013, 48). In other words, these objects have implanted expertise to cooperate with inner state or external surroundings. Seemingly, when objects are in a position to sense as well as correspond, it changes where and how assessments are formulated as well as who creates them.

... Affiliation: Portfolio Optimization Asset Allocation A variation of different assets will provide the investor with a variability of return in the investor’s portfolio and reduce the risk. In order to achieve portfolio optimization the investor has to allocate the portfolio in different asset classes. The most beneficial way to allocate the assets is to let a global touch permeate the portfolio. Look at different national markets in order to find independency, hence reduce the risk (Litterman, 2003).
In order to attain optimization at a national level it is of great importance to look at different type of sectors and industries, this is supported by Litterman (2003). ). The investor treats the national market as a global...

(Peelen, 2005:3). The most sweeping definition of CRM was given by Regis McKenna, who recognizes that CRM targets the building of an infrastructure which may be used to develop long-term customer-supplier relationship, which is the integration of customers in the company’s design, development, manufacturing and sales processes. (Peelen, 2005: 5). CRM consists of sophisticated software and analytical tools that integrate customer information from all of those sources, analyse it in depth, and apply the results to build stronger customer...
Intangible Specialization And Product-Mix Optimization
intangible specialization (is)
Intangible specialization is the concept comprising of relationship between path dependence, set of routines (i.e. intangible capital accumulation), and level of uncertainty in competition among automobile manufacturers (Maeilli, 2005, p.249). The term (IS) is associated broadly with planning, designing, and ethics of business under new set of rules and procedures. New set of routines are appreciated in business environment but they are usually unstable and uncertain.
Intangible capital encompasses “identifiable non-monetary assets that cannot be seen, touched or physically measured, which are created through time and/or effort...
... in the area of operation of the company.
Intangible specialization may be advantageous or a limitation to the company. This is mainly dependent on the strategies that the company formulates while factoring in the strengths and weaknesses due to its intangible specialization in a certain area of operation. One of the main benefits of intangible specialization is that it may help a company overcome different financial difficulties if efficient strategies are put in place to enable it to have output-mix optimization in the area where it has intangible specialization.

Yet the concept of globalization has undergone radical changes in the past century. Now it stands for something more than just the diffusion and osmosis of the economic, social, and political theories, practices, and technologies. Now every country is as much part of globalization as globalization has become a part of every country. Globalization is as much a universal phenomenon as it is an internal phenomenon. It is not only the exchange of knowledge or adoption of better technologies. The meaning of globalization is not only limited to the idea of modernization or imitating a certain culture or practice. Globalization in itself has become a culture in its own rights and it has managed to bring the world closer. Now events ha...
Resistors are very essential in electronics. They are the most generally used electronic component. The main function of resistors is to resist or block electrons movement. A part from resisting electrons flow, resistors do also divide voltage in a circuit. Several types of resistors and manufacturing techniques do exist. Resistors are manufactured in different forms. Their formation range from small surface mount chip to huge wire wound power resistors. The way resistors are formed depends a lot with the work they are supposed to do. This paper therefore seeks to evaluate various studies done on current types of resistors and the techniques used when being manufactured.
