ACTIVITY DIAGRAMS IN UML Activity Diagrams WHAT IS AN ACTIVITY DIAGRAM? Activity diagrams consist of activities‚ states and transitions between activities and states. Activity diagrams combine ideas from event diagrams‚ Petri nets and state modeling techniques An activity diagram is a special case of state charts in which most or all states are activity states and most or all transitions are triggered by the completion of activities in the source state. What is an Activity Diagram? The

Yesterday I saw the news about the lab-grown burger. It immediately created a mix of feelings. It’s definitely an important mark for science but it doesn’t seem to be the solution for the increasingly consumption of meat. Having that said‚ today’s post is going to be a little different than usual. World’s population is rising significantly‚ and it’s expected to be around 9 billion by 2050. It not only brings problems like space but also food shortage onward with scarcity of natural resources

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but

Dependencies and Network Diagram The network diagram is a schematic representation showing the sequence and relationship/ dependency of the tasks along with their duration. All the tasks‚ except the first and the last‚ are linked with at least one predecessor and successor to have a proper sequence of work. This logical dependency between the tasks will determine afterwards the duration of the project. There are four types of dependencies which define the relation between pair tasks Finish-to-start

Dated: 12-04-2013 STEPS INVOLVED IN THE SELECTION FLOW METER There are well over 20 different types of flow meters‚ even if we lump the various positive-displacement flow meters together as one type. Unless the process engineer knows the pros and cons of each type‚ it can be a daunting task to properly select one. Here are just some of the factors to consider before selecting a flow meter: • Its size and measuring range of the flow meter • Chemical compatibility • Process accuracy requirements•

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax
