    Having scandalous unethical research practices in the mid and late 20th century, study protocols of biomedical research reviewed by the Ethics Committee (EC) has become the accepted international standard. The Declaration of Helsinki uniformly requires that all biomedical research involving human participants, including research on identifiable human material or data, should be approved by the EC. Today, concerns over the quality of the EC functions worldwide. There are research globally in this regard but no data are available from Bangladesh. Hence, we conducted a questionnaire based pilot study on knowledge and attitude of EC members on bioethics and structure & function of EC in Bangladesh

    A Dual-Rate Model Predictive Controller for Fieldbus Based Distributed Control Systems

    In modern Distributed Control Systems (DCS), an industrial computer network protocol known as fieldbus is used in chemical, petro-chemical and other process industries for real-time communication between digital controllers, sensors, actuators and other smart devices. In a closed-loop digital control system, data is transferred from sensor to controller and controller to actuator cyclically in a timely but discontinuous fashion at a specific rate known as sampling-rate or macrocycle through fieldbus. According to the current trend of fieldbus technology, in most industrial control systems, the sampling-rate or macrocycle is fixed at the time of system configuration. This fixed sampling-rate makes it impossible to use a multi-rate controller that can automatically switch between multiple sampling-rates at run time to gain some advantages, such as network bandwidth conservation, energy conservation and reduction of mechanical wear in actuators. This thesis is concerned about design and implementation of a dual-rate controller which automatically switches between the two sampling-rates depending on system’s dynamic state. To be more precise, the controller uses faster sampling-rate when the process goes through transient states and slower sampling-rate when the process is at steady-state operation. The controller is based on a Model Predictive Control (MPC) algorithm and a Kalman filter based observer. This thesis starts with theoretical development of the dual-rate controller design. Subsequently, the developed controller is implemented on a Siemens PCS 7 system for controlling a physical process. The investigation has concluded that this control strategy can indeed lead to conservation of network bandwidth, energy savings in field devices and reduction of wear in mechanical actuators in fieldbus based distributed control systems

    “Electronic Banking” refers to the systems that enable bank customers’ access to accounts and general information on bank products and services through a personal computer (PC) or other intellectual devices. Internet facilities have been introduced in Bangladesh in June 1996 beginning a new era of automated banking and commerce. E-banking is the cornerstone and waves of the future banking services and security. Now most of the banks in Bangladesh are providing a number of E-Banking services and playing a pivotal role. E- Banking services is one of the great initiatives to bestow a part of modern world. It provides gigantic benefits to consumers in terms of case and cost of transactions, either through internet, telephone, mobile or other electronic delivery channels. For many consumers, electronic banking means 24-hours access to cash through an Automated Teller Machine (ATM) or Direct Deposit of paychecks into checking or savings accounts. But in present time E-Banking involves numerous types of transactions. E-Banking offences are earlier occurred in   Bangladesh. For the expansion and safeguard of transaction in country, here exist different types of laws. Laws look after the consumer's rights and liability with banking safety. Laws have been enacted in this field for interest of consumer and bank to ensure their function, duty and rights as so as liabilities. For personal and governmental safety there exist some rules and regulation and also those have some loopholes. This paper represents the painstaking scenario of e-banking services, offences and how laws cop and formulate a better e-banking environment in Bangladesh and tried to simplify future problems and ultimate possibilities to drawbacks them from E-Banking. Key words: e-banking offences, e-banking laws, e-banking in Bangladesh, Banglades
