Concrete works in most of the construction projects can be broken down into three main items; Formwork, Steel work, and concreting, No doubt, concrete works account for a large portion of construction projects budgets. As stated by Awad S. Hanna (1999), formwork material and labor can account for 40 to 60 percent of the cost of concrete works; however this percentage can vary slightly from country to another. That is why it is important to select an appropriate formwork system for a project; otherwise the project cost will be affected negatively. Formwork systems can be classified by their function into …

A Novel Versatile Cmos Operational Floating Current Conveyor Amplifier, Nermine Maher Edward
Theses and Dissertations
Nowadays, current mode devices are used as active elements at the circuits that work at high frequencies. A novel integrated CMOS based the operational floating current conveyor (OFCC) is proposed. OFCC is a five port general purpose analog building block which combines all the features of different current mode devices such as the second generation current conveyor (CCII), the current feedback operational amplifier (CFA), and the operational floating conveyor (OFC). The OFFC is modeled and simulated using UMC 130nm technology kit in Cadence and the supply voltage of the proposed OFCC is 1.2V. Non-inverting voltage amplifier, current mode instrumentation amplifier …
