Project Report on Bridging the Gap between the Channel Partners and the Company: an empirical study of Grameenphone Ltd.
(East West University, 4/25/2009) Wahed, Abdul
Grameenphone Ltd. Has stepped into its 12th year of operation, on March 26, 2009. It is the leading telecommunications service provider in the country with more than 20 million subscribers as of December 2008. Grameenphone has been recognized for building a quality network with the widest coverage across the country while offering innovative products and services and committed after sales service. GP knows that in near future, the sell will sluggish down due to overall economic downfall and all the activities; mainly customer retention will occur through effective and efficient after sales service. And for that, GP always wants to give their priority to this sector. All the activities of Grameenphone Ltd. is based on this motto. As mobile operators sell services to customers, the quality is measured by the after sales service and product availability. If the product is not easily available, on the other hands, if the distribution channel is not strong enough, the switching cost is higher for any company. The raison d'ctre of this study is measure whether the distribution of product supply that is the "money transfer" facility which keeps any cell phone operator alive, is adequate or not as far as Grameenphone Ltd. is concerned.
Solid State Lighting, A solution for Power Crisis in Bangladesh
(IEEE, 2016-10-28) Zaman, K. M. Ahsan-uz; Ullah, Kafi Mohammad; Milon, Md. Shaidul Kabir; Sayam, A S M; Wahed, Abdul
Electricity is the most usable form of energy. For a developing country like Bangladesh, electricity plays an important factor. Due to increasing population and rapid industrial growth, the country lags behind than its rising demand of electric power supply. Power generation in Bangladesh is mostly dependent on natural gas, coal and fossil fuel which are also responsible for carbon emission. Alternative measures should be taken to resolve this power crisis. If the present power consumption can be reduced using smart energy efficient appliances then it would be possible to meet up the demand of the consumers with the present production capacity. Lighting is responsible for a gentle amount of energy consumption over the year. In this paper we discussed about using smart technologies like Solid State Lighting in terms of reducing energy consumption on lighting sector. Light emitting diode (LED) based solid state lighting technology have potential to exceed the efficiency of conventional lamp based lighting systems. LED offers better quality in lighting, have much longer lifespan and comparatively better on durability with only drawback of initial high pricing. In terms of much longer lifespan, this initial cost is not much accountable. This paper represents the features and efficiency of solid state lighting as well as comparison among conventional lighting and LEDs.
